Family drug courts increase parental success in treatment, decrease the time children spend in foster care, and increase family reunification rates. Nevertheless, evidence suggests many parents in dependency proceedings have open criminal cases or are at risk for engaging in criminal activity (Kissick et al. Cost savings from reduced use of foster care were estimated to be approximately $10,000 per child in one study in Maine (Zeller et al. The studies estimated net cost benefits to local communities ranging from approximately $5,000 to $13,000 per family (Burrus et al. The child welfare system realized the greatest cost savings as a result of reduced use of foster care. Community corrections reaped the second greatest savings as a result of parents spending less time on probation or in jail. Notably, the treatment system was the only agency that did not reap net cost benefits. Retain high-need parents or guardians in treatment for at least 15 months (Green et al. Deliver individual counseling to parents or guardians on a weekly basis for at least the first phase of the program (Worcel et al. Administer evidence-based family counseling interventions that are documented in treatment manuals. Schedule frequent status hearings and ensure the judge speaks directly to participants in court, treats them with respect and dignity, and expresses support and optimism for their recovery (Lloyd, M. Provide parenting classes that teach participants effective child caretaking, supervision, and disciplinary skills (Carey et al. Provide specialized services for families affected by methamphetamine, including neuropsychological testing and individualized educational plans Family drug courts produced net economic benefits for local communities of approximately $5,000 to $13,000 per family. Ensure staff members receive annual training on addiction neuroscience, evidence-based family interventions, and specialized services for abused, neglected, and traumatized children (Lloyd, M. Juvenile Drug Courts More than 250,000 teens are arrested each year in the United States for drug- or alcohol-related infractions (Puzzanchera, 2013). Between one-half and three-quarters of juvenile arrestees use illicit drugs or alcohol, and over one-quarter meet diagnostic criteria for a moderate-to-severe substance use disorder (Abram et al. Between 50% and 70% of juveniles in detention have a co-occurring psychiatric disorder (Colins et al. Recidivism rates in the juvenile justice system commonly exceed 70% (Mulder et al. Unfortunately, most dispositions in the juvenile justice system have produced outcomes ranging from harmful to modestly beneficial. Meta-analyses reveal that traditional juvenile justice case processing, juvenile detention, and "scared straight" programs increase recidivism by 6% to 8% (Aos et al. Programs that provide treatment or social services in lieu of punishment can reduce juvenile recidivism by approximately 7% to 10%, which statisticians characterize as a small effect (Aos et al. However, one meta-analysis focusing exclusively on randomized experiments found no effects of treatment-diversion programs for juveniles (Schwalbe et al. In addition to receiving treatment, participants appear regularly before a judge for status reviews, undergo frequent drug and alcohol testing, and receive escalating incentives for achievements and sanctions for infractions (Butts & Roman, 2004). Early meta-analyses reported an average reduction in recidivism of less than 5%, which was only marginally statistically significant (Aos et al. More recent meta-analyses have reported an average reduction in recidivism of approximately 8%, which although statistically significant, is still small in magnitude (Mitchell et al. More than three-quarters of juvenile drug courts were deficient or needed improvement in applying evidence-based practices. Providing unnecessary services to low-risk or lowneed teens-or worse, mixing them in treatment groups with high-risk peers-is strongly associated with negative outcomes, including increased recidivism, substance misuse, and school dropout (DeMatteo et al. Research in adult drug courts reveals that programs are approximately twice as effective at reducing crime and 50% more cost-effective when they serve high-risk, high-need individuals (Marlowe, 2012c). Deliver incentives, assign parent peer mentors, or administer other family-engagement techniques to enhance parent or guardian attendance at court hearings and family counseling sessions (Drabble et al. Teach parents or guardians effective ways to monitor youth behavior, deliver effective reinforcement and discipline, and provide consistent emotional support (Alarid et al. Reduce youth associations with substance-using and delinquent peers (Schaeffer et al. Conduct status hearings in front of a judge as opposed to a community panel (Cook et al. Perform frequent (at least weekly) drug and alcohol testing for high-risk youths (Korchmaros et al. Administer sanctions of moderate severity for willful program infractions (Korchmaros et al. Avoid costly and ineffective reliance on jail or detention sanctions, especially as a response to positive drug tests (Carey et al. Ensure staff members receive annual training on adolescent development and evidence-based practices for substance-involved youths in the juvenile justice system (Linden et al. Approximately 60% to 80% of justice-involved veterans had a substance use disorder prior to incarceration, 25% to 40% were suffering from a mental health disorder, and 23% were homeless at some point in the year preceding their arrest (Blodgett et al. Approximately 25% of incarcerated veterans report having been under the influence of drugs or alcohol at the time of their offense (Bureau of Justice Statistics, 2007). Similarly, a pre/post evaluation of the Rochester (New York) Veterans Court reported a 59% reduction in arrests after participants entered the program (Commaroto et al. Although this evaluation did include a comparison group, the results may be unreliable because persons who refuse to enter treatment often have worse prognoses to begin with than those who accept treatment, such as lower motivation for change, more severe symptoms, or less supportive social networks (Heck, 2006; Marlowe, 2010a; Peters, 1996). In addition to treatment, participants appear regularly in court for status reviews before a judge, undergo frequent drug and alcohol testing, and receive steadily escalating incentives for achievements and sanctions for infractions (Clark et al. Successful graduates may have their criminal charges dropped or reduced, or in post-sentencing programs can avoid incarceration or receive a substantially reduced term of probation (Smee et al. Traumatic exposure during combat, difficulty reintegrating into civil society after discharge, and the unique socialization processes of military culture may require veteran-specific services to be delivered in separate court-based programs by fellow veterans who are familiar with combat and military lifestyle (Ahlin & Douds, 2015; Bryan & Morrow, 2011; Clifford et al. These targeting criteria may be important from a policy or fiscal perspective, but their relevance to treatment planning and outcomes is as yet uncertain. As previously discussed, decades of research in drug courts (and mental health courts) indicates programs are most effective and costeffective when they match services to the risk and need profiles of their participants (Marlowe, 2012c). Provide housing assistance for veterans who are homeless or have unstable living arrangements (Elbogen et al. Implement evidence-based interventions to help participants cope with daily stressors and reintegrate into civilian life (Blevins et al. Educate family members and significant others about warning signs and methods for dealing with medical and mental health symptoms commonly experienced by combat veterans. Participants receive mental health treatment and intensive clinical case management. Comparable studies are lacking for co-occurring disorders courts, which serve persons suffering from both a severe and persistent mental illness and substance use disorder. Studies are needed to camaraderie for participants, and ensure they attend treatment services and prosocial events. This practice borrows heavily from the peer-support specialist model, which is used most commonly with teens and persons with severe substance use disorders. However, little research is available to indicate how peer-support programs should (and should not) be structured and implemented. Mental Health Courts Approximately 15% to 20% of persons on probation or parole (Feucht & Gfroerer, 2011) and in jail or prison (Fazel & Danesh, 2002) suffer from a serious mental health disorder. Individuals with mental illness fail disproportionately on probation and parole (Skeem et al. Specifically, outcomes are better when participants receive services matched to their levels of risk and need, and when they are not mixed in treatment groups with higher risk or higher need peers (Rojas & Peters, 2015; Skeem et al. In one study, participants who were prescribed psychiatric medication were seven times more likely to graduate successfully from drug court than participants with mental health symptoms who did not receive psychiatric medication (Gray & Saum, 2005). Mental health courts have a moderate effect in reducing recidivism, and the effects last at least two years. Cost-Effectiveness of Mental Health Courts Cost-effectiveness analyses have produced mixed findings. These findings do not, however, suggest persons with these characteristics should be treated in 29 Painting the Current Picture: A National Report on Drug Courts and Other Problem-Solving Courts in the United States Participants are matched to indicated treatment services based on standardized mental health and substance use disorder assessments. Participants receive weekly written reminders about their treatment schedule, homework assignments, and other requirements in the program. Drug and alcohol testing is performed randomly at least once per week, usually more often, including on weekends and holidays. Incentives and sanctions are delivered rapidly and reliably during frequent status hearings. Compliant participants are acknowledged in court through an "honor roll," and noncompliant participants are required to observe court sessions from the jury box or front row of the courtroom. Incentives for achievements are provided liberally, including tangible rewards. Continuing care is emphasized through mentor programs, alumni groups, or extension of the last phase of the program for participants who are reticent about graduation. Community Courts Community courts primarily address "quality of life" crimes, such as vagrancy, petty theft, turnstile jumping, vandalism, loitering, and prostitution. The programs are often situated in circumscribed neighborhoods or boroughs of a city or municipality and emphasize restorative justice interventions such as community service in lieu of traditional criminal justice sanctions. Many community courts offer treatment and social services at or near the courthouse and work closely with volunteer community boards or local police to supervise participants and encourage them to give back to their community as compensation for the harm or inconvenience they may have caused (Lee, 2000). Effectiveness of Community Courts Studies indicate community courts are significantly more likely than traditional criminal courts to link participants with needed treatment and social services, impose alternative sanctions such as community service in lieu of incarceration, and ensure adequate compliance with community service and other court-imposed obligations (Hakuta et al. They are also less likely to impose negligible sentences on participants, such as time served in pretrial detention, which typically have little effect on recidivism and may promote a "revolving door" of repetitive arrests and dispositions (Sviridoff et al. Finally, researchers consistently find that participants in community courts perceive significantly higher levels of procedural fairness and satisfaction with the court system than matched defendants undergoing traditional adjudication, and perceptions of procedural fairness are correlated with better long-term outcomes (Frazer, 2006; Lee et al. Community courts are more likely to link participants with needed treatment and social services, impose alternative sanctions such as community service, and ensure compliance with court-imposed obligations. Studies have reported mixed results concerning the impact of community courts on criminal recidivism. Similarly, a study in San Francisco reported a significant pre/post reduction in rearrest rates in a community court catchment area after the program opened, after accounting for a wide range of potentially confounding factors (Kilmer & Sussell, 2014). Importantly, however, the magnitudes of the effects on recidivism differed substantially between programs. Rearrest rates were 42% to 60% lower for community court participants in the District of Columbia, 14% lower for community court participants in Melbourne, 9% to 10% lower in San Francisco, and only 4 percentage points lower in Brooklyn. On the disappointing side, several studies of community courts reported no significant effects on recidivism. A study of prostitution cases in the Midtown (New York City) Community Court found no difference in rearrest rates for community court participants compared to matched cases from an adjacent precinct, although it did find lower overall neighborhood arrest rates for prostitution offenses after the court opened (Sviridoff et al. Given the wide range of recidivism outcomes, it is premature to conclude whether community courts are effective at reducing rearrest or reconviction rates. Target Population for Community Courts No effort has been made to identify the appropriate target population for community courts. Because these programs typically handle low-level nuisance or summary offenses, participants may, on average, have lower levels of risk or need than other programs targeting more serious felony and misdemeanor cases. Moreover, community courts may have insufficient leverage over some participants to keep them engaged in treatment if the alternative sentence for their crimes is likely to be negligible in length or severity. Community courts may need to target more serious cases presenting with higher levels of risk and need to achieve effective and costefficient results. One study of a community court in Vancouver, Canada, specifically targeted high-risk participants presenting with complex treatment and social service needs (Somers et al. Interventions included the provision of wraparound services by a multidisciplinary outreach team. Results revealed significantly fewer new convictions for community court participants compared to matched individuals undergoing traditional adjudication. Because lowrisk and low-need individuals were not included in the analyses, it is not possible to determine whether comparable results can be achieved for persons with less complex service needs. Studies are needed that assess risk and need levels of community court participants and examine the impact of risk and need on participant outcomes. Best Practices in Community Courts Few efforts have been made to identify best practices in community courts. Perhaps because many participants face negligible alternative sentences if they fail to complete community court, some programs have required relatively minimal levels of treatment and case management services. For example, participants in a community court in Brooklyn, New York, typically received only 5 days of treatment and social services, and rarely received more than 30 days of treatment (Lee et al. Not surprising, 31 Painting the Current Picture: A National Report on Drug Courts and Other Problem-Solving Courts in the United States this minimal dosage of treatment was determined to have had no impact on outcomes. In contrast, as already mentioned, assertive case management using outreach workers was found to significantly improve outcomes for high-risk participants in a community court in Canada (Somers et al. This finding suggests community courts may be more effective if they target intensive clinical case management services to high-risk and high-need participants. Considerably more research is needed to identify other best practices that can improve outcomes in community courts. When the survey was launched, respondents received an email notification that included the survey link, confidential login information, and instructions on how to complete the survey. Reminder emails were sent periodically over a period of five weeks to encourage prompt and accurate completion of the survey. Survey respondents were instructed to answer questions whenever possible based on statewide or territorial data. For jurisdictions that did not 2 Data for Hawaii was reported only for the Big Island. Research Summary More research has been published on drug courts and other problem-solving courts than virtually all other criminal justice programs combined. Not content to stop there, researchers are unpacking the "black box" of these programs and discovering how they work, why they work, and for whom they are best suited. Implementation studies are now needed to ensure these programs serve their appropriate target populations and apply best practices to achieve optimum results. Other drug courts and problem-solving courts are still in the process of examining effectiveness and cost-effectiveness. Other programs, such as domestic violence courts, reentry courts, co-occurring disorders courts, and prostitution courts, have not been studied sufficiently to assess effectiveness. More work lies ahead to measure the effects of these programs and determine how they should be structured and implemented to achieve the best outcomes. Efforts are ongoing to improve the performance of drug courts and other problem-solving courts, and in so doing improve the functioning of the justice system, protect public safety, and save thousands of lives. Participants in the military Target population for veterans treatment courts Veterans tracks in drug courts or mental health courts Drug courts closed Reasons for closing drug courts Service gaps in drug courts Dispositional models of adult drug courts Offense levels in adult drug courts Outcomes for felons vs. Number of Drug Courts by Year in the United States Year 1989 1990 1991 1992 1993 1994 1995 1996 1997 No. Response rates for some items are substantially below 98% because not all jurisdictions collected relevant information in a reliable manner. Moderate response rates (between 70% and 85%; green font in the table) may not be nationally representative. Some items were not applicable for all jurisdictions; therefore, those jurisdictions were not included when calculating the response rate for these items. At the end of 2014, there were 62 co-occurring disorders courts in the United States. As of December 31, 2014, there were 3,057 drug courts in the United States, representing a 24% increase in five years. In contrast, juvenile drug courts, family drug courts, reentry drug courts, and campus drug courts experienced slight to moderate decreases in numbers. Jurisdictions are considered to have expanded drug courts substantially if they opened at least 20 new drug courts in five years and grew proportionately by at least 35%. By this definition, over one-quarter of states and territories (n = 14, 26%) expanded drug courts substantially. Jurisdictions Drug Court Snapshot Numbers and Models of Drug Courts As of December 31, 2014, there were 3,057 drug courts in the United States, representing a 24% increase over the previous five years (Tables 3 and 4 and Figure 2). Adult drug courts were by far the most prevalent model, accounting for just over one-half of all drug courts. Number of Drug Courts by Year in the United States 3,500 3,000 2,500 2,000 1,500 1,000 500 0 1989 1994 1999 2004 2009 2014 Table 4. Three states (California, Kentucky, and New York) reported having at least 10 fewer drug courts in 2014 than in 2009. Regional patterns in drug court expansion or contraction are not readily apparent (Figure 3). Jurisdictions that substantially increased drug courts by more than 20 programs are variously located in Southern (Alabama, Arkansas, Georgia, Texas), Northern (Michigan, Minnesota, Wisconsin), Eastern (Pennsylvania, Ohio), Midwestern (Illinois, Indiana), Western (Washington), Southeastern (West Virginia), and Rocky Mountain (Colorado) states. The three states that reported at least 10 fewer drug courts are located on the west coast (California) and east coast (New York) and in the southeast (Kentucky). Of all the drug court models, by far the largest proportional growth since 2009 was seen in veterans treatment courts. An additional 78 drug courts or mental health courts had specialized tracks for military veterans or active-duty military personnel.

Dark colored or bloody urine is frequently not noticed by patients because the abnormal color is only visible when the urine is collected in a cup. The abnormal color is not noticeable in a urine stream unless the urine color is very dark. Screening urinalysis may often identify persistent microhematuria which eventually resolves months later. Glomerulonephritis may also be related to hepatitis B and C as well as syphilis infections. One way to sort out the etiology of the glomerulonephritis is to look at the complement level and whether evidence of systemic or renal disease is present. In a patient with normal serum complement level and evidence of systemic disease consider polyarteritis nodosum, Wegener vasculitis, Henoch-Schonlein purpura and hypersensitivity vasculitis. Vasodilators such as calcium channel blockers are also used to manage hypertension. Indications for hospitalization include: an uncertain diagnosis, significant hypertension, anticipated poor follow-up, cardiovascular or cerebrovascular compromise, etc. Parents must notify the physician when the blood pressure exceeds the parameters given by the physician. The presence of red cell casts on urinalysis almost always indicates the presence of glomerulonephritis. An uncertain diagnosis, significant hypertension, anticipated poor follow-up, cardiovascular or cerebrovascular compromise, etc. His eyes are non-injected, his conjunctiva are not edematous and his throat is not red. Abdomen is soft, non-tender, non-distended and without masses or shifting dullness. Nephrotic syndrome describes the collection of clinical and laboratory findings secondary to glomerular dysfunction, resulting in proteinuria. The diagnostic criteria are marked proteinuria, generalized edema, hypoalbuminemia, and hyperlipidemia (with hypercholesterolemia). The proteinuria in nephrotic syndrome is severe, exceeding 50 mg of excreted protein for every kilogram of body weight over 24 hours. Primary nephrotic syndrome refers to diseases limited to the kidney, whereas secondary nephrotic syndrome indicates systemic diseases that include kidney involvement. In healthy children (less than 18 years of age), the annual incidence of nephrotic syndrome is 2-7 new cases per 100,000. The prevalence is approximately 16 cases per 100,000 children, making nephrotic syndrome one of the most frequent reasons for referral to a pediatric nephrologist. Also, the most common type of nephrotic syndrome is recurrent to some degree, so cases will often manifest repeatedly over time. In early childhood, males outnumber females about 2:1 for new cases of nephrotic syndrome. Primary nephrotic syndrome is more common in children less than six years of age, while secondary nephrotic syndrome predominates for patients older than six. The disease inheritance is usually sporadic, although there is a congenital form of nephrotic syndrome, called Finnish type congenital nephrosis, which is inherited in an autosomal recessive manner. This abnormality has been mapped to a defect in the nephrin gene on chromosome 19q13. The main pathogenic abnormality in nephrotic syndrome is an increase in glomerular capillary wall permeability, resulting in pronounced proteinuria. The normal glomerular wall is remarkably selective for retaining protein in the serum. Once this selectivity is lost, the excretion of large amounts of protein will follow. This increase in permeability is related to the loss of negatively charged glycoproteins within the capillary wall that usually repel negatively charged proteins. The predominant protein lost is albumin, although immunoglobulins are also excreted. A simplification of the predominant theory is that after the plasma albumin concentration drops, secondary to protein excretion, the plasma oncotic pressure drops. With the decrease in oncotic pressure, fluid moves from the intravascular space to the interstitial space causing edema. The liver has a very large capacity to synthesize protein, so the persistent hypoalbuminemia is likely not due entirely to increased losses. Reduction of the intravascular volume results in activation of the renin-angiotensin-aldosterone system. There are likely other factors involved in the formation of edema, because some patients with nephrotic syndrome have normal or increased intravascular volume. The hyperlipidemia in nephrotic syndrome is characterized by elevated triglycerides and cholesterol and is possibly secondary to two factors. The hypoproteinemia is thought to stimulate protein synthesis in the liver, including the overproduction of lipoproteins. Also lipid catabolism is decreased due to lower levels of lipoprotein lipase, the main enzyme involved in lipoprotein breakdown. More than 90% of children with primary nephrotic syndrome have idiopathic nephrotic syndrome and this will be the focus of this chapter. The etiology of this condition remains largely unknown, but some have postulated an immunologic mechanism. Supporting evidence for this theory include the characteristic response to corticosteroids and cytotoxic agents, an observed increased incidence of concurrent allergic conditions, and spontaneous remissions with natural measles infections (known to induce suppression of cell-mediated immunity). Evidence against an immunologic etiology is a failure to identify immune reactants or inflammation in kidney biopsies. There are three morphological patterns of idiopathic nephrotic syndrome, with minimal change disease (also called "nil disease") making up 80-85% of the cases. In this condition, the glomeruli appear normal or have a minimal increase in the mesangial cells or matrix. As well as being the most common form of primary nephrotic syndrome, minimal change disease also has the mildest clinical course. The rest of this chapter will focus on this disease entity after briefly describing the other forms of primary nephrotic syndrome as well as secondary nephrotic syndrome. The less commonly seen types of primary idiopathic nephrotic syndrome are focal segmental glomerular sclerosis, membranous glomerulonephritis and membranoproliferative glomerulonephritis. Focal segmental glomerular sclerosis is found in about 7-15% of patients with nephrotic syndrome, making it the second most common primary renal lesion. It tends to have a more severe clinical course with persistent proteinuria, progressive decline in glomerular filtration rate and hypertension that can be unresponsive to therapy. Renal failure occurs, with dialysis or transplant being the only treatment options. Unfortunately, the recurrence rate of focal segmental glomerular sclerosis can be as high as 40% after renal transplant. Membranoproliferative glomerulonephritis accounts for roughly 7% of primary idiopathic nephrotic syndrome. The clinical course is variable with only a small percentage of patients going into remission. Membranous glomerulopathy is rare in the pediatric age group, but becomes more common into adolescence and adulthood. The clinical course is variable, but the overall prognosis is good, with spontaneous remission of proteinuria occurring in 50-60% of cases. These include multisystemic diseases such as systemic lupus erythematosus and Henoch-Schonlein purpura, malignancies such as Hodgkin disease or leukemia, drug or toxin exposures such as mercury, gold, penicillamine or bee sting, and infectious etiologies such as Epstein-Barr virus, cytomegalovirus and tuberculosis. Page - 447 Children with idiopathic nephrotic syndrome secondary to minimal change disease usually present with edema. Clinically apparent edema usually is not seen until albumin levels drop below 2 g/dL. Over the course of a day, the edema often distributes from the eyes to more dependent areas. After time, the edema becomes more pronounced, generalizes and there can be weight gain. Patients or parents may notice tighter fit of clothes, belts and shoes and scrotal or labial edema often occurs. As the edema accumulates, pleural effusions, ascites and decreased urine output may develop. Anorexia, abdominal pain and diarrhea may be seen, possibly secondary to the formation of ascites. The hallmark of nephrotic syndrome is severe proteinuria, most reliably diagnosed using a 24-hour urine collection. Spot urinalysis is also informative and reveals +3 to +4 proteinuria (300 to 1000 mg/dL), with a specific gravity usually greater than 1. Because of the hypoalbuminemia, hypocalcemia is often seen, with calcium levels less than 9. Hyponatremia and hyperkalemia can be seen, with hyperkalemia developing in patients who are oliguric. Renal biopsy is not necessary for the child with newly diagnosed nephrotic syndrome and the initial treatment will be the same, regardless of the cause. If the response is good and renal function is normal, the diagnosis of minimal change disease may be presumed. If relapses respond to corticosteroids and there is no proteinuria during disease free periods, this diagnosis is strengthened. Biopsy is generally obtained in cases where there is poor or no response to corticosteroids, the patient is less than 1 year old (high likelihood of congenital nephrotic syndrome) or over 10 years old, secondary nephrotic syndrome is suspected, there is corticosteroid toxicity, or the use of a cytotoxic agent is being considered. Patients with low serum complement levels or hypertension on presentation may require biopsy since these conditions are not characteristic of minimal change disease and may indicate other renal lesions. The treatment of primary idiopathic nephrotic syndrome of childhood is corticosteroid therapy and supportive care. Many patients may be treated on an outpatient basis, although the newly diagnosed patient is sometimes admitted for diagnostic and educational purposes. Edema is managed with sodium restriction (the "no added salt diet") and diuretics such as hydrochlorothiazide. If hypokalemia develops, an oral potassium supplement or spironolactone may be added. Aggressive use of loop diuretics may be harmful since most patients initially presenting with nephrosis are hypovolemic. Patients need to monitor their weight closely and consume adequate amounts of protein. Conditions that require immediate attention and hospitalization are severe scrotal edema, dehydration (more than 10% dehydrated), respiratory compromise due to pulmonary edema or pleural effusions, and peritonitis or suspected bacterial infection. Despite their edematous appearance, most patients have decreased intravascular volumes. Therapy is aimed at the restoration of intravascular volume and preventing volume overload. Intravenous fluids are used, sometimes with the infusion of albumin to increase the serum oncotic pressure. The albumin must be given slowly, over 8-12 hours, to prevent fluid overload from rapid intravascular volume expansion. There is some debate over the use of albumin, since the effect seems to be transient and it is presumably excreted rapidly (1). Once the intravascular volume is restored, diuretic therapy is used to mobilize the fluid and prevent volume overload. Paracentesis is performed if there is respiratory compromise secondary to severe ascites. Antibiotic therapy to cover for the most common pathogens should be started if there is evidence of bacterial infection (discussed below). Minimal change disease is characteristically responsive to corticosteroid therapy and once the diagnosis is confirmed with laboratory testing, steroid therapy should be started. Prednisone is initiated with a dose of 60 mg/sq-meter/day or 2 mg/kg/day divided in 2-3 doses. Regardless, the corticosteroids are continued and then tapered over the course of 3-6 months. In patients with minimal change nephrotic syndrome, approximately 98% will eventually have satisfactory therapeutic responses. This disease is one of frequent relapse, with two thirds of patients having a single relapse and roughly one third experiencing repeated relapses over many years. Most patients with steroid-responsive nephrotic syndrome will continue to have relapses until they are in their late teens. With repeated relapses or severe steroid toxicity (growth retardation, elevated blood pressure), cytotoxic agents such as cyclophosphamide are added to a lower corticosteroid dose. This agent has been shown to prevent relapses and to increase the duration of remission. Chlorambucil and less commonly cyclosporine have also been used for remission induction. The most common complications of nephrotic syndrome are bacterial infection and thromboembolism. There are also complications secondary to medications such as the gastric irritation and insulin resistance seen with corticosteroids or the hemorrhagic cystitis, sterility and leukopenia seen with cyclophosphamide. The tendency to develop infections, especially "primary peritonitis" (a type of pneumococcal sepsis), is thought to be due to IgG excretion, decreased complement function, and diminished splanchnic blood flow. The organisms causing peritonitis are most commonly Streptococcus pneumoniae and Escherichia coli. Peritonitis should always be considered in a patient who has nephrotic syndrome and abdominal pain or fever. Antibiotics such as ampicillin or vancomycin with a third generation cephalosporin or an aminoglycoside would provide good empiric coverage. Other infections such as sepsis, cellulitis, pneumonia and urinary tract infection are also seen. The signs of infection may be masked if the patient is currently on corticosteroid therapy. Any child with nephrotic syndrome and a fever must be thought of as having an infection until proven otherwise, since they are at high risk for sepsis, similar to splenectomy patients. Venous thrombosis is most common, especially in the renal vein, pulmonary artery, and deep vessels of the extremities. In patients with refractory nephrosis, low dose anticoagulants are sometimes used. The prognosis for children with minimal change nephrotic syndrome is good, with most patients ultimately becoming disease free and living a normal life. Mortality is approximately 2% with the majority of deaths being secondary to complications such as peritonitis or thromboembolic disease. True/False: A renal biopsy is necessary to confirm the diagnosis of primary idiopathic nephrotic syndrome. Minimal change disease or "nil disease" accounts for 80-85% of cases of primary idiopathic nephrotic syndrome in childhood. Infection, especially peritonitis and thrombosis account for the majority to nephrotic syndrome mortality. The decision to perform a renal biopsy is usually deferred until the initial course of corticosteroid is initiated, unless there are specific risk factors such as age below one or above 10, hypertension on presentation or decreased complement on presentation. Nephrotic syndrome in a child less than 1 year old may indicate congenital nephrotic syndrome and renal biopsy is often performed. Shirakawa A one month old female is brought to her pediatrician with a chief complaint of an abdominal mass. Her mother noticed the mass earlier in the week and immediately made an appointment to see the pediatrician. The mother also notes that the infant has been frequently wetting her diapers, although there is no history of fever, vomiting or diarrhea. Her physical exam is unremarkable except for a nontender 7 cm by 8 cm left-sided abdominal mass. A renal ultrasound is ordered and reveals bilateral enlargement of her kidneys with diffuse echogenicity and microcysts. The infant is diagnosed with autosomal-recessive polycystic kidney disease and a possible urinary tract infection. Her renal function is sufficient, but it is anticipated that it will worsen as she grows. Cystic kidneys in children and adolescents present in various forms and can range from a single cyst to multiple bilateral cysts. In this chapter, a few of the more common disease conditions will be discussed: multicystic dysplastic kidneys, autosomal recessive polycystic kidney disease and autosomal dominant polycystic kidney disease. Other cystic kidney diseases that will not be discussed include nephronophthisis (a common genetic cause of chronic renal insufficiency in children which presents with polyuria and polydipsia, anemia and growth retardation), medullary cystic disease (autosomal dominant disease in which young adults develop renal failure), medullary sponge kidney (dilated intrapapillary collecting ducts and multiple small cysts that usually presents in adulthood), glomerulocystic kidney disease (seen in a variety of inherited syndromes), simple renal cysts (incidental findings that generally do not impair renal function), multilocular cysts (unilateral benign tumor), acquired cystic kidney disease (occurs in patients with renal failure), and syndromes with cystic kidneys (such as tuberous sclerosis, Meckel syndrome, and von Hippel-Lindau disease). The classic type contains multiple cysts of various size, with an abnormal renal shape and an atretic proximal ureter. The hydronephrotic type is rarer and consists of peripheral cysts that communicate with a large central cyst with a dilated pelvis and calyces (1). The most recent studies estimate that the incidence is 1 in 2400 livebirths, and it is more common in males (1,2). The disease usually occurs unilaterally, but can be seen bilaterally in as many as 20% of cases (2). The first proposes that abnormal induction of the metanephric blastema leads to dysplasia of the renal parenchyma that is non-uniform, resulting in cysts that increase in size and eventually compress normal renal tissue (1). In unilateral cases, there is a compensatory hypertrophy in the contralateral kidney.

Those who have had stem cell transplants require immunization erectile dysfunction hypertension drugs cheap sildalist 120mg with amex, usually beginning three to six months after transplantation erectile dysfunction at 18 generic sildalist 120mg amex. Screening for Second Cancers Second and higher order primary cancers often occur several years popular erectile dysfunction drugs order sildalist 120 mg amex, even decades erectile dysfunction doctor new jersey discount sildalist 120mg with mastercard, after treatment for the primary cancer erectile dysfunction fact sheet purchase 120mg sildalist with mastercard. There is little question that younger cancer survivors should undergo screening for second cancers erectile dysfunction foods to eat generic 120mg sildalist mastercard, but there is not necessarily a consensus regarding screening for second primaries when the cancer survivor is an older adult erectile dysfunction drugs that cause sildalist 120 mg otc. The concern is that older patients may not tolerate treatment as well as younger individuals erectile dysfunction 22 order sildalist 120 mg fast delivery. Age should not be the only criteria on which to make screening decisions; performance status can be more important than age in determining if a particular individual is a candidate for treatment if a second primary is found. It is important for patient and provider to thoroughly discuss all concerns and to periodically revisit the issues. Patients who have recently completed difficult treatment regimens may initially decide that they will never undergo such treatment again, but may feel differently when faced with a new cancer. It is often difficult to tease out which of these are caused by cancer treatments versus genetic, environmental, and other factors that may have led to the development of the initial malignancy. Family history may suggest the presence hereditary predisposition to certain cancers, as can age at diagnosis. Patients whose cancers occur at younger ages than usual or whose families contain cancer clusters should be referred for genetic counseling and testing. The presence of a mutation is often important in guiding screening and risk reduction for siblings or children of cancer survivors. The risk of cancer recurrence is higher in the first few years after treatment, whereas second primaries may not manifest themselves for many years. Screening for recurrence is considered part of surveillance, whereas screening for new primaries is considered secondary screening. Based on information from National Comprehensive Cancer Network, 2013a; National Comprehensive Cancer Network, 2013d; National Comprehensive Cancer Network, 2013e; National Comprehensive Cancer Network, 2013j. Certain treatment modalities increase the risk of secondary primary cancers in cancer survivors. Anthracyclines/Herceptin the anthracyclines can cause cardiac toxicity because of oxidative stress of the myocardial cells, which will induce apoptosis (Arozal et al. This can lead to congestive heart failure, arrhythmias, and left ventricular dysfunction. Because of the cardiotoxic effects of these agents, they have a maximum cumulative dose. If the cumulative dose exceeds above the maximum dose established for each agent the probability of developing cardiac dysfunction increases greatly. Therefore if at all possible, these agents should be avoided or careful monitoring of cardiac function must occur during administration. Other agents not in the anthracycline family can increase the risk of cardiac dysfunction so other agents with cardiotoxicities should be avoided. If cardiac toxicities do occur with anthracycline therapy, Copyright 2014 by the Oncology Nursing Society. Finally, side effects may not present immediately during exposure to the agents but may occur years after therapy has completed. Trastuzumab-related cardiac dysfunction is different from chemotherapy-induced cardiac dysfunction in that it does not generally cause death and is reversible once the drug is stopped. If cardiac dysfunction does occur with the administration of trastuzumab, once the agent is discontinued cardiac function will usually recover to normal, and the agent can often be restarted (Carver et al. Studies are also looking at the use of biomarkers such as brain neutriarectic peptides, and troponins that may indicate myocyte damage earlier (Horacek et al. Bleomycin Bleomycin has been known to cause pulmonary toxicity and Raynaud phenomenon. Injury of the alveolar capillary barrier, neutrophil accumulation, and induction of pro-inflammatory cytokines in turn causes pulmonary fibrosis. Because of the risk of pulmonary fibrosis, the maximum lifetime dose is 400 units. If patients who have received bleomycin must undergo surgical procedures with administration of anesthesia, the use of high-dose oxygen therapy must be limited to reduce the risk of postoperative ventilation failure. High levels of oxygen are used during scuba diving, so this activity should also be limited or avoided (Zaniboni, Prabhu, & Audisio, 2005). There have been some case reports of gangrenous digits after the administration of bleomycin (Chaudhary & Haldas, 2003). Renal toxicities are associated with the platinum-based agents especially cisplatin. Cisplatin is turned into a much more potent toxin, which in turn causes cell apoptosis, inflammation, and necrosis. To ensure that long-standing renal insufficiency does not occur, careful monitoring of renal function and electrolytes and administration of diuretics and fluids are imperative during treatment. However, patients may still develop long-term renal insufficiency despite these measures. Optimization of renal function, avoidance of nephrotoxic agents, and strict management of comorbidities that can contribute to renal insufficiency, such as hypertension and diabetes, are necessary (Polovich, Whitford, & Olsen, 2014). Immunomodulators the uses of lenalidomide and thalidomide have been associated with an increased risk of developing secondary malignancies such as lymphomas and acute myeloid leukemia. Ongoing studies are continuing to look into this phenomenon (Ormerod, Fausel, Abonour, & Kiel, 2011). In most cases if the drug is stopped or dose reduced, the neuropathies will resolve without any other intervention. Current studies are ongoing looking at the use of glutamine and glutathione in peripheral neuropathy treatment. Safety modifications to reduce falls due to decreased proprioception and deep tendon reflexes should be employed (Polovich, Whitford, & Olsen, 2014). Vinca Alkaloids Mixed sensory and motor neuropathies are often dose limiting and may continue to worsen even after agent discontinuation. Constipation, mega colon, and paralytic ileus have occurred due to the autonomic neuropathy (Polovich, Whitford, & Olsen, 2014). Alkylating Agents these agents are known to cause gonadal dysfunction, which can affect both hormones and fertility. This may be due to the rapid proliferation of urothelial cells observed in hyperplastic urothelium caused by Copyright 2014 by the Oncology Nursing Society. The lowest dose of the agent should be used, and those patients who have received more than 20 grams of cyclophosphamide should undergo routine urinalysis every three to six months to screen for microhematuria (Vlaovic & Jewett, 1999). It has also been associated with the development of acute leukemia in patients treated with cyclophosphamide for lymphomas (Ng, La Casce, & Travis, 2011). Rituximab One study showed an increase risk for myelodysplasia or acute leukemia with the addition of rituximab to high sequential therapy for lymphoma patients. Bone Marrow Transplant Patient who have received allogeneic bone marrow transplants are at risk for secondary malignancies along with graft versus host disease. The most common is nonmelanoma skin cancers and squamous cell cancer of the buccal cavity. Management of Long-Term Side Effects Thyroid Screening Patients who have undergone radiation therapy to the neck for lymphoma, head and neck malignancies, or radioactive iodine will need to have lifelong monitoring for thyroid dysfunction. Cognitive Impairment Cognitive impairment is commonly referred to by many patients, survivors, and providers as "chemobrain. It can have a profound impact on the quality of life after treatment has been completed. Some studies have tested the use of psychostimulants but have failed to show benefit (Raffa, 2011). Other studies have looked at the use of cognitive training, but these have been small samples and lacked a comparison group. More randomized controlled studies are needed to examine at effect evidence based interventions. Neurologic Impairment Chronic peripheral neuropathies can have a profound impact on quality of life. The use medications such as topical lidocaine, neuroleptics and opiate may be necessary for adequate pain control. These patients will most likely benefit from a pain management or neurology consult. Patients are also at risk for falls and injury due to proprioception and temperature changes. Referral to physical therapy may be beneficial (Polovich, Whitford, & Olsen, 2014). Ocular and Auditory For patients who have been treated with busulfan, long-term steroids, cranial radiation, or tamoxifen should undergo annual eye examinations to screen for cataracts. Cisplatin, high-dose carboplatin or ear irradiation, may also have a long-term effect on hearing. If hearing loss occurs after treatment with cisplatin, the patient should undergo and audiology evaluation (Polovich, Whitford, & Olsen, 2014). Oral Cavity Patients who experience dry mouth after radiation therapy have a risk of dental caries due to lack of saliva. Measures to help promote saliva production such as prescribing pilocarpine can be initiated. To reduce the development of dental caries, biannual dental examinations should be completed and fluoride treatments should be initiated (Polovich, Whitford, & Olsen, 2014). Cardiovascular All patients who have received cardiotoxic agents should undergo serial echocardiograms every year to assess function. If patients have received cardiotoxic agents and continue to experience cardiac issue, they should be referred to cardiology work up. All patients who have received cardiotoxic agents should undergo routine laboratory studies to assess lipid profile. They also should be monitored for hypertension and signs of congestive heart failure. If patients have hypertension or dyslipidemia, they should be managed appropriate with health behavior modification such as diet and exercise. If patients experience signs and symptoms of congestive heart failure, immediate referral to a cardiologist is warranted. Patient who have also undergone radiation to the neck are at risk of developing carotid stenosis. Currently, patients should undergo carotid artery ultrasounds every two to three years or if symptoms warrant evaluation. Pulmonary Patients who have received pulmonary toxic agents should have pulmonary function test routinely and for any new pulmonary symptoms. If there are changes in pulmonary status, Copyright 2014 by the Oncology Nursing Society. For those patients who have undergone treatment with bleomycin, it is prudent that their oxygen exposure is limited so that ventilation failure does not occur (Zaniboni et al. Patients should also undergo vaccines to prevent pneumococcal infection as needed and an annual influenza vaccination. Genitourinary Patients who received cyclophosphamide will need to undergo annual urinalysis to screen for hematuria. If microscopic hematuria is detected ultrasound of kidneys, urine culture and spot urine calcium/creatinine should be ordered. If these come back negative, the patient many need to undergo further urologic evaluation with urine cytology or cystoscopy (Vlaovic & Jewett, 1999). Reproductive and Gonadal Function All sexually active patients are advised to use some form of birth control during treatment. Women may not only become infertile from treatment but may also experience premature menopause. Because of estrogen deficiency, early menopause can place women at risk for osteoporosis, atherosclerosis, hot flashes, and mood swings (Polovich, Whitford, & Olsen, 2014). These women should undergo bone densitometry evaluation and be treated based on these results. Focus should also be on reducing the risk of cardiovascular disease, including screening for hypertension, diabetes, and dyslipidemia along with treatment of abnormalities. The use of hormone replacement and use of herbal therapies for treatment of postmenopausal symptoms should be avoided (Polovich, Whitford, & Olsen, 2014). If a woman must undergo treatment, is of childbearing years, and still would like to have children, several fertility-preserving methods are being investigated. Methods of cryopreservation of ovarian tissue and oocytes are currently being studied. Unfortunately, this is not feasible because the procedure requires at least two to five weeks of ovarian stimulation and oocyte collection, which would delay treatment. Ovarian stimulation is also not recommended in women who have hormone dependent tumors (Ribeiro-Campos & Japur de Sa Rosa-e-Silva, 2011). Men who are undergoing chemotherapy and are still hoping to have children have the option to sperm bank. This option should be offered to all males receiving chemotherapy or undergoing a surgical procedure that could affect fertility or sexual function (Ng et al. The patient may have presenting symptoms, new findings on radiologic examinations, or abnormal laboratory values. The referral back to the oncologist should be done in a timely fashion, and the patient should also be notified of the reason for the referral. Additional Work-Up Before the Referral Additional evaluation will also depend on the presentation of the potential recurrence. If the patient presents with specific symptoms, radiology examinations and laboratory studies may be warranted. However, once again the specific testing will be based upon the original cancer diagnosis. The radiology examination would most likely be looking for a cause of the symptom. This would help identify a recurrence, possible side effect of treatment, or new underlying condition. Symptoms Suspicious for Recurrence Back Pain Back pain could be a sign of cord compression or a tumor on the spine. The patient should also be assessed for bowel and bladder incontinence or retention as this may also indicate a cord compression. However, the cancer survivor evaluated to identify if recurrence has occurred or if this is a side effect or previous treatment. The work up will be based upon location, type, frequency, duration, onset, character, aggravating factors, and relieving factors. Radiology examinations may also be necessary, depending on the location and suspicion for a malignancy. Abdominal Pain or Fullness this symptom would be more suspicious in patients that have either had gastrointestinal, genitourinary, or gynecologic malignancies. A patient may be eating the same caloric intake but still losing weight or may have early satiety or reduced appetite. Shortness of Breath Dyspnea could be an indication recurrence, metastasis, or side effect of previous treatment. A pulmonary function test may also be helpful in patients who have received bleomycin to rule out pulmonary toxicity from chemotherapy. Bleeding A complete blood count should be done to assess hemoglobin, hematocrit, and platelet count. The location of the bleed will help determine the type of radiologic testing that should be completed. For those patients who have a history of a leukemia or lymphoma this could be an indication of thrombocytopenia due to marrow involvement. It also could be due to a high prothrombin time, partial thromboplastin time, or international normalized ratio due to liver dysfunction or liver metastasis. Skin Changes Skin changes may be indicative of late side effects of treatment such as radiation or chemotherapy. Patients who have had skin cancer and present with a new lesion that is irregular in shape, changed, is larger than 6 mm, or has irregular borders, or lesions that will not heal, bleed, or evolve over time should be referred to an oncologist or dermatologist. With the continued advancement in cancer treatments, the number of cancer survivors continues to grow (American Cancer Society, 2013). Cancer survivorship is a journey that flexes between different phases and transitions. After active cancer treatment ends cancer survivors return to their Primary Care Physician or Nurse Practitioner for routine care and follow-up. As a result of the unpredictable nature of cancer, the majority of cancer survivors battle with the fear of cancer recurrence (Gorman, 2006). These include disease-related issues, such as site, stage, treatment, and rehabilitation. Holland (2003) also stated that personality, coping skills, belief system, culture, and support from others play a key role in the ability to adjust to their situation. Even with continued education and support from the healthcare team, cancer survivors and their families expect to immediately transition from active treatment to surveillance and follow-up. Although their treatments have ended, their mental and spiritual outlook may still be focused on dealing with the aftermath of their cancer diagnosis. Oftentimes, cancer survivors will experience similar emotions and stress related to the completion of treatment as they did when they were first diagnosed. Cancer survivors may battle the fear of cancer recurrence or finally be able to deal with emotions they buried so they could be mentally strong enough to complete treatment. As their active treatment ends, survivors may experience a form of separation anxiety resulting from decreased interactions with their medical team (Boyle, 2006). Survivors may have concerns that they will have questions about their condition and no one will assist them; oftentimes, this can increase their fear of recurrence (Boyle, 2006).

The most common worrisome organisms include Campylobacter erectile dysfunction keywords generic sildalist 120mg with mastercard, Salmonella diabetic erectile dysfunction icd 9 code sildalist 120 mg on-line, Shigella erectile dysfunction treatment new jersey cheap sildalist 120 mg on line, and enterotoxigenic E coli erectile dysfunction treatment cream safe 120 mg sildalist, but other routine pathogenic bacteria and protozoans can be acquired from contaminated food and standing water sources prostaglandin injections erectile dysfunction 120 mg sildalist fast delivery. The first 4 are routinely included in culture screens for enteric pathogens (the rest are not) low cost erectile dysfunction drugs buy discount sildalist 120 mg. Shigella also warrants antibiotic therapy if found erectile dysfunction 9 code order 120mg sildalist free shipping, and while treatment of Salmonella may raise the risk of producing a chronic carrier state erectile dysfunction treatment boots 120 mg sildalist sale, since most carriers arise from colonization of the gallbladder, cautious treatment with an agent concentrated in bile (such as trimethoprim/sulfamethoxazole) if the organism is sensitive may be warranted in the patient with ongoing or severe symptoms. The one organism whose treatment with antibiotics or antispasmodics is to be avoided is enterotoxigenic E. Use of these agents can produce enough enterotoxin release as to trigger Hemolytic Uremic Syndrome. Antibiotics should be held until the offending bacteria is positively identified, and even over the counter antispasmodic agents are to be avoided. Epstein-Barr virus can cause lymphoproliferative disease with chronic low-grade blood Page - 365 loss and more of a protein losing enteropathy picture. Typhlitis also occurs in the patient recovering from neutropenia as the new granulocytes are preferentially directed toward the inflamed cecum. The latter instance is indicative of stricture at the anastomotic site and recurrence of functional obstruction. As a stasis phenomenon it can also be seen in those with ileorectal pouches and other anastomosis, and while it can cause bleeding, it usually presents with explosive, foul diarrhea. Other processes that can cause moderate bleeding volumes, usually as part of a broader clinical picture include general obstructive processes such as intussusception, volvulus, and other mechanical issues that can cause focal bowel ischemia. They usually present with other signs of obstruction, typically with an acute onset of crampy abdominal pain that cycles every 10 to 60 minutes as the major migrating motor complex passes through the obstructed segment. Waiting for the passage of currant jelly stool (bloody stool) before considering intussusception in the differential diagnosis is to be discouraged since this is a late finding. In fact, the possibility of intussusception should be considered when any type of blood in the stool is encountered. In patients presenting similar to the above, but with lesser signs of obstruction, consideration should be given to vasculitis, far more commonly due to anaphylactoid (or Henoch-Schonlein) purpura than to Systemic Lupus Erythematosus. The typical presentation is dominated by crampy pain with a usually minor bleeding component. Treatment with corticosteroids is discouraged until these entities and lymphoma or leukemia are more definitively ruled out. Poor weight gain and especially linear growth can be noted as much as 6 months before onset of cramping and bleeding, though there are hyper-acute variants of ulcerative colitis. In ulcerative colitis, the blood and stool texture are inversely related, with both mucusy diarrhea and bleeding being indicators of inflammation. And finally, among the (relatively) common causes of colonic bleeding, polyps are to be considered whenever there is a report of painless bleeding of apparently moderate volume. Solitary juvenile polyps are the most common, and typically do not become large enough to cause bleeding before the end of the second year. As hamartomas, they are extremely vascular but have no sensory tissue and bear essentially no neoplastic risk as long as they are indeed solitary. The familial polyposis syndromes produce diffuse adenomatous polyposis, resulting in studding of the mucosa with often nearly confluent polyps, all of roughly the same size. It remains to be seen if this significantly reduces the longterm neoplastic risk, but it seems to permit a reduction from the every-other-year colonoscopy surveillance often undertaken in the second decade. The diagnosis of polyps (single or multiple) starts with the history of painless bright red bleeding, generally without anemia despite a protracted history, and no anal fissure on inspection. Digital rectal examination is usually diagnostic as most solitary polyps arise within the last 2 inches of the rectum, and the familial adenomatous polyposis syndromes result in many small polyps within reach. Therapy for isolated polyps is endoscopic removal and for multiple polyps is endoscopic sampling to establish a diagnosis. Waiting for a polyp to autoinfarct will not permit specific identification as to type, and the presence of more than 3 polyps, even with a "juvenile" type histology, is still associated with a higher risk of eventual colon cancer. Recent advances in genetic screening in the diagnosis and management planning of the familial adenomatous polyposis syndromes in pediatrics was recently discussed in detail in reference #6. Even with hemorrhage, patients rarely become significantly Page - 366 volume depleted on an acute basis and in most instances there is enough time to perform appropriate testing, including culture, in a sequential manner. Many times, the workup of the crampy patient with modest bleeding in loose mucusy stools involves a quick survey of inflammatory markers and a 2 to 3 day wait for the culture results from the rectal swab. A rectal swab has a superior yield over culture of stool material because the center of the lumen. On the other hand, finding a solitary polyp on initial examination permits a relaxed scheduling on a more elective basis both for the physician and the family. Rectal examination finds a single 1 cm pedunculated polyp 2 cm from the anal verge. Colonoscopy is scheduled, as the prep for even proctoscopy for polypectomy requires stringent removal of all stool to prevent a short-circuit current and an unintended burn, and a search is to be made for further polyps. The gastroenterologist reports no others are seen and the polyp in question has been easily removed by an electrocautery snare. You are called to the nursery where you are shown a burp cloth with loose clots of regurgitated blood. The newborn in question is sleeping quietly, with completely normal vital signs and no sign of tenderness or other bleeding when examined. At a two month well baby visit, his parents bring in a diaper double-bagged because of the foul odor. The stool is tarry and tests positive for occult blood, but the child appears particularly robust, having gone from a birth weight of 7 pounds 1 ounce to his current weight of 12 pounds 10 ounces. He is somewhat fussy and demanding of feedings, and his mother complains of getting no rest as she has to feed him hourly. Recently, her left breast has become quite sore and there is intense pain when he nipples. On examination, the infant is colicky, but there is no abdominal tenderness and his vital signs are also within normal limits with no adjunct signs of intravascular volume depletion. A 14 year old female has yet to show secondary sexual development which you have always attributed to excessive involvement with the school track team. A 3 year old boy presents to the emergency department passing bright red blood per anus. He is diaphoretic and tachycardic (120 supine, 140 upright) and complains of generalized abdominal pain. You are unable to localize tenderness but are comfortable that there is no rebound tenderness and he is not at risk of perforation. By the time you have given enough crystalloid to replete his blood volume, his hemoglobin has dropped to 7 grams. Since his summer physical 2 months ago had included a hemoglobin of 12, you realize he has indeed lost a substantial portion of his blood volume over a short period of time. He is admitted to the hospital, where over the next two days as you wait for the stool culture results. He requires 250 cc transfusions daily to maintain his hemoglobin and you realize that the brisk bleeding continues.

Take the loose clots and suspend them in a minimal amount of tap water (you need a visibly pink supernatant composed of free hemoglobin, hence the tap water to lyse the cells). Centrifuge the cells and to 5 cc of pink supernatant add 1 cc of 1% sodium hydroxide. Read in two minutes: adult hemoglobin turns yellow or brown, fetal hemoglobin remains pink. This infant has no sign that the bleeding originates with him, as bleeding sufficient to produce melena should leave him quite shocky. The history gives every sign that he has induced a mastitis (and nipple bleeding) in his mother, and she is able to compensate for the several ounces of blood loss that produced the melanotic stool. You counsel her on proper feeding and handling techniques to keep the infant satisfied without having to overfeed, and have his mother avoid feeding on the affected side until the inflammation subsides. He shows no sign of acute intravascular volume depletion, but looks a little pale and turns out to be mildly anemic, indicating a longer standing problem. There is evidence of bleeding in an area bathed in acid, but it is not the stomach (or the duodenum). This finds a hot spot in the lower mid-abdomen which the technician assures you is not tracer in the bladder. If this occurs and the transit time is relatively slow, bleeding in this area can present as melena. The acid level in the stomach is low (possibly due to antacids and H2 blockers) and/or the bowel transit time is very rapid. Also, the bleeding may originate from the duodenum which does not expose the blood to acid if the pylorus is tight or the level of stomach acid is low. The history has all the hallmarks of inflammatory bowel disease, but still the common things are more common. The physical examination shows no weight loss (but little net gain over the year), and she has a mild temperature elevation (100. You are puzzled until the stool culture results return 2 days later, positive for Campylobacter. You call to discuss the results and find her new puppy had been ill the week before (dogs can both harbor and become ill from this organism), and the poor race performance actually arose because she was getting fed up with her coach (her father) and had been wanting to quit. Since she is still out of school with the cramping and diarrhea, you start her on erythromycin, offer to act as a go-between on the issue of changing sports, and annotate her chart to remind yourself to monitor for other signs of depression in the future. With this you joyfully cancel the colonoscopy as being unnecessary, and chalk up the experience as a reminder that rapid transit times and the low acid production of early childhood can sometimes prevent the blood from encountering enough acid to turn to acid hematin or melena. Indeed, the higher the volume lost, the more acid is needed and the less likely the reaction. Unfortunately, as the finding was a therapeutic surprise, you are unprepared to address the ulcer in any invasive manner (sclerotherapy, heater probe, etc. Preparations are made to return with the proper equipment the next day if he continues bleeding, only to find the bleeding stops with the procedure (and the drop in splanchnic pressures encountered under anesthesia), the current measures are more than sufficient, and no further transfusions are required. The patient makes a rapid and full recovery, with no recurrence in over 5 years (based on actual personal experience). Further questioning finds that she has had similar episodes in the past few years, but none as severe as the current episode. There are mildly hyperactive bowel sounds with diffuse vague abdominal pain without any point tenderness. Rectal exam demonstrates non-specific discomfort without masses or severe tenderness. The two diseases are prevalent in North America, northwestern Europe, and in the United Kingdom. This is in comparison to the decreased rates in Southern Europe, South Africa, and Australia. Caucasians, especially Ashkenazi Jewish, have a greater risk than other ethnicities. Viruses and Mycobacterium paratuberculosis are some of the organisms that have been studied. There are multiple studies attempting to isolate the gene(s) involved in this disease that are beyond the scope of this chapter. The big picture is that multiple events have an additive effect that results in an abnormal mucosal immune response, which leads to intestinal inflammation. Weight loss, poor weight gain, anorexia, and delayed growth occur in 40% of cases. This growth abnormality may present as short stature and/or delay in sexual maturation. Mild disease is defined as less than 6 stools per day, no fever, no anemia, and no hypoalbuminemia. Moderate disease is described as more than 6 stools per day, fever, anemia, and hypoalbuminemia. Severe disease exhibits high fever, abdominal tenderness, distention, tachycardia, leukocytosis, hemorrhage, severe anemia, and more than eight stools per day. Rare complications that may arise include toxic megacolon and intestinal perforation. The diagnosis is based on clinical presentation, radiologic findings, endoscopy with mucosal biopsy, and exclusion of other causes. Since corticosteroids will likely be used for treatment, stool cultures are done to rule out infectious causes. Colonoscopy is superior to evaluate the large bowel because of its increased sensitivity and biopsy capability for histologic assessment. Further studies may show specific nutritional deficiencies including iron deficiency, hypoalbuminemia, and elevated transaminases. Its low sensitivity and specificity have kept these studies from replacing definitive radiologic and endoscopic studies. Care must be taken to rule out bacterial causes of diarrhea prior to starting systemic corticosteroid therapy. Metronidazole is used for both active disease, as well as prevention of recurrence. Azathioprine and 6mercaptopurine are immunomodulating drugs which are used to reduce inflammation of the intestines, so that the corticosteroid doses can be reduced. Surgical resection is indicated when there are intractable symptoms despite medical therapy, intestinal complications, intraabdominal abscesses, bowel-bladder fistula, perforation, and/or hemorrhage. In some patients, elective colectomy is performed to reduce or eliminate the risk of colon cancer. As listed above, growth impairment may occur either secondary to the illness or to therapy. Most patients undergo resection of the affected segment within 20 years, which decreases the overall incidence of carcinoma. Ulcerative colitis is also divided into 3 categories, which include mild, moderate and severe disease. One large study noted 70% of children entering remission by three months despite their initial severity level. The greater the severity of the disease, the greater was the likelihood of undergoing a colectomy. Nine percent and 25% those with moderate to severe disease underwent colectomy by 1 and 5 years, respectively. Since there is such a high risk, regular colonoscopic surveillance is recommended, which identifies colorectal cancer at a potentially curable stage 65% of the time. However, these biannual examinations that start at 7-10 years of disease were not found to be cost effective. Genetics versus the environment in inflammatory bowel disease: results of a British twin study. Further history reveals a past history of anemia, anorexia, and minor abdominal pain. Her mother also questions whether the symptoms could be related to a recent move from their home state of Minnesota. Because of her small size and amenorrhea, a bone age reveals a 3 year delay and suggests osteopenia. Her reticulocyte count is low and her iron studies indicate the presence of iron deficiency. A lactose breath hydrogen test showed an elevation in hydrogen of 40 ppm, suggesting carbohydrate malabsorption. Biopsies from the duodenal and proximal jejunal area reveal severe villus atrophy consisting of a flat mucosa with deep crypts and no evidence of Giardia lamblia. She responds dramatically and upon follow-up is now reporting an increased appetite and improved mood. She has also noticed a resurgence in her growth and has reported menarche that started about a month ago. Gluten-sensitive enteropathy, also known as sprue, celiac sprue and celiac disease, is one of the many causes of malabsorption. Malabsorption is a clinical term for the entire spectrum of conditions occurring during digestion and absorption of ingested nutrients by the gastrointestinal tract. Perturbations in the digestion and absorption of food nutrients can occur either in the luminal phase, the mucosal phase, or the transport phase of the ingested food. Classifying the many entities of malabsorption in this manner makes it easier to understand their exact mechanisms. Causes of malabsorption can be explained by the way the disease process interferes with the normal digestive and absorptive mechanisms. Malabsorption encompasses conditions that go from a single nutrient malabsorption. Celiac disease is manifested variably by malabsorption to different types of nutrients. While presenting symptoms such as diarrhea and weight loss are common, the specific cause of malabsorption should be established using physiological evaluations. The treatment of the underlying disease is often dependent on the establishment of definitive cause for the malabsorption. Were it not for the logical steps followed by the clinician, the quite dramatic resolution of symptoms brought about by denying the patient food devoid of gluten would not have happened if the exact etiology was missed. As emphasized before, the causes of malabsorption can be best appreciated if they are classified into the specific phase of digestion and absorption that is disturbed. The luminal phase is where dietary fats, proteins, and carbohydrates are hydrolyzed and stabilized by digestive enzymes and bile.

A peak flow meter can consistently record airflow readings compared against normal values for sex and age erectile dysfunction medications injection discount sildalist 120 mg overnight delivery. Signs of "silent asthma" (when no wheezing is heard) include: persistent cough at night impotence fonctionnelle cheap sildalist 120 mg amex, cough with exercise erectile dysfunction doctor in philadelphia buy sildalist 120 mg overnight delivery, cough with laughter erectile dysfunction injections youtube sildalist 120 mg fast delivery, cough when consuming cold foods or drinks erectile dysfunction doctor in nj sildalist 120mg, prolonged cough following or accompanying a cold erectile dysfunction young adults discount 120 mg sildalist mastercard, feeling of "tight chest" or difficulty breathing erectile dysfunction viagra dosage sildalist 120 mg on line. Full pulmonary function testing is desirable; however psychological erectile dysfunction drugs 120 mg sildalist otc, the equipment is expensive compared to an inexpensive peak flow meter. The ultimate objective measurement for asthma is by body plethysmography (body box), which can measure the end expiratory residual lung volume as well as resistance to airflow. For those patients unable to perform peak flow measurements, clinical history is all you may have to base your conclusions. This includes a major group of younger asthmatics from infancy to 4 or 5 years old. Many children in this age group are unable to reliably perform peak flow measurements. The identification of the role of allergic diseases in asthma relies heavily on patient history. Physicians trained to respond to record what they feel, see, and hear may have a problem forming conclusions based on history alone. Soft signs indicating that asthma is out of control include: frequent overt wheezing episodes, increasing frequency of using rescue medications. Good communication and availability to answer questions and concerns are basic to the partnership. Part of your efforts as the treating physician should be focused on getting the patient to respond in a logical manner to cope with changes in his/her clinical state. This is based on the patient understanding the principles of: triggers and aggravators, bronchodilation, inflammation, airway hyper-reactivity and healing. Patients must also understand mucous mobilization and signs and symptoms of asthma out of control which may lead to an acute asthma attack. For example, should the peak flow fall or cough increase, the patient is instructed to upgrade their medications according to a prearranged plan. As the acuteness of the situation resolves, the patient is advised to downgrade their medications back to their maintenance program. Should there be an unanticipated episode of wheezing, immediate activation of the action plan and consultation with the physician for additional treatment schemes is the next step. Obviously, recurrent wheezing episodes, even if reversed easily might indicate the presence of an unstable condition requiring an Page - 298 adjustment in the basic asthma management plan. Higher severity levels warrant greater use of corticosteroids and prophylactic medications such as leukotriene inhibitors and inhaled corticosteroids. Step 2 (mild persistent): Day symptoms greater than two times per week, but less than once per day or night symptoms greater than nights per month. Step 3 (moderate persistent): Day symptoms occur daily or night symptoms occur more than once per week. The use of peak flow in the above classification is not required in children 5 years and under. Peak flow data is useful but not required for classification in older age groups, but most children in this age range are capable of performing peak flows. The major goal is to allow the child to express and achieve his or her maximum natural potential by not allowing the asthma to control him or her. Along the way, it is crucial to cradle the impressionable self image so that the child does not have a negative view of himself or herself. The very impressionable years are from about 3 to 10 years of age, when children form their life-long mental image of themselves. Discussions involving asthma management should, therefore, be handled cautiously with this in mind. Bronchodilators In 1896 Solis-Cohen published, "The use of adrenal substances in the treatment of asthma" (adrenalin or epinephrine is a fast and potent bronchodilator). Epinephrine (most commonly administered subcutaneously, but it could be inhaled as well) was the first line of treatment for acute asthma from the 1950s through the 1970s and early 1980s. Ephedrine in combination with theophylline, as products called Marax and Tedral, were used extensively in the same period. Interestingly, the ancient Chinese boiled the ephedra root in strong tea for their concoction to treat asthma. Although methylxanthines such as theophylline are effective bronchodilators, they have been largely replaced by beta-2 agents. Adding theophylline does not appear to acutely benefit most patients who are receiving high therapeutic doses of albuterol. This change in therapeutic approach from methylxanthines to beta-2 agents did not further our understanding of the true pathophysiology of asthma, as bronchodilation was the only target of treatment. In general, inhaled medications have a faster onset, greater potency and less side effects. Anti-Inflammatory Drugs Based on the biphasic mechanism, an anti-inflammatory drug. For asthma of a chronic nature, such as allergic asthma to house dust, a daily regimen of a long acting bronchodilator coupled with a steroid by inhalation would be effective. They have an array of impressive and undesirable side-effects, which cause hesitation in their use by physicians as well as patients. As in the use of any medication or therapeutic agent, the employment of steroids is subject to weighing the desired effects against the undesirable effects (benefit vs. If the positive effects of using steroids have an overwhelming advantage over not using the drug, then it is justified to be used on a regular basis. Many patients require more medications during the fall/winter/spring, and fewer medications during the summer. Occasional bursts of systemic corticosteroids have no significant long term side effects, but chronic or long term use of systemic steroids have major side effects (refer to the chapter on corticosteroids). They have less potent anti-inflammatory properties, but they have minimal side effects. Prevent recurrent exacerbations of asthma and minimize the need for emergency department visits or hospitalizations. Alternatively, a cromolyn medication or a leukotriene receptor antagonist may be used. Step 3 (moderate persistent) recommends a low dose inhaled corticosteroid plus a long acting beta-2 agonist (salmeterol or formoterol). Step 4 (severe persistent) recommends a high dose inhaled corticosteroid, plus a long acting beta-2 agonist. In addition to the above chronic (long-term) recommendations, acute exacerbations are treated with quick relief (or rescue) medications, which is most commonly prn albuterol and optional short bursts of systemic corticosteroids. Systemic corticosteroids are usually given for 4 to 5 days and then discontinued if the patient improves. Systemic corticosteroids administered for longer than 7 days require a gradual taper of the medication. If the patient is on inhaled corticosteroids, these should be resumed once systemic corticosteroids are stopped or tapered. Some physicians continue inhaled corticosteroids during systemic corticosteroid bursts to avoid the confusion caused by modifying their chronic medications. All patients should have a written asthma management plan that describes their chronic medications and a plan for the initiation of a rescue plan based on their symptoms and peak flow (if age >5 years). More detailed plans can include recommendations to step up or step down their chronic medications as their chronic symptoms worsen or improve. Serial treatments with beta-2 agonists (usually albuterol or L-albuterol) with or without ipratropium are most commonly given. Inhaled beta-2 agonists can be given continuously for severely ill patients, or serially based on severity. Parenteral corticosteroids do not have an onset time advantage over oral corticosteroids; however, very ill children have a higher likelihood of vomiting oral prednisolone. The decision to start systemic corticosteroids is based on their response to beta-2 agonists and their previous history which indicates their severity level. Those who do not respond well to beta-2 agonists should be started on systemic corticosteroids because, poor response indicates the presence of significant bronchial Page - 300 inflammation Those who have required systemic corticosteroids in the past or who have other markers of more severe asthma should also be started on systemic corticosteroids. Characteristics of good asthma control in children include: no coughing, no shortness of breath or rapid breathing, no wheezing or chest tightness, no waking up at night because of asthma symptoms, normal activities including play, sports, and exercise, no episodes of asthma that require a doctor visit, emergency room visit, or urgent care, no absences from school or activities, no missed time from work for the parent or caregiver, normal or near normal lung function, and a healthy self image. Unfortunately, the death rate from asthma is not yielding to the introduction of many excellent and powerful treatments. This condition remains a challenge to the medical care team at all levels from physicians, nurses, emergency technicians, and respiratory therapists to psychiatrists and social workers. Family, school personnel, coaches, club leaders, and after hours activity supervisors, are all involved in delivering care to the asthmatic. Risk factors for death from asthma include: Past history of sudden severe exacerbations. Acute signs of severe asthma and potential impending respiratory failure, warranting admission to an intensive care unit include: 1) Oxygen saturation less than 100% despite the administration of supplemental oxygen. The treatment of severe status asthmaticus bordering on respiratory failure is controversial. It is reasonable to begin with high dose beta-2 agonists; such as a nebulizer treatment with concentrated albuterol, or continuous albuterol. In severe patients, aeration is poor, so inhaling albuterol by itself is usually insufficient. Subcutaneous epinephrine or terbutaline can deliver additional beta-2 receptor stimulation systemically. Such patients should be treated aggressively from the onset to prevent respiratory failure. If the patient fails to improve and respiratory failure ensues, positive pressure ventilation should be directed at maintaining oxygenation above 90% saturation if possible. Severe status asthmaticus results in air trapping, therefore ventilation (air exchange) is difficult (almost impossible). This strategy is known as "permissive hypercapnia" because hypercapnia is not as deadly as hypoxemia. Permissive hypercapnia is more likely to avoid a pneumothorax and thus, oxygenation is preserved, improving the overall outcome. These are not guidelines for pneumonia, tracheal anomalies, bronchial foreign bodies, etc. Environmental measures to reduce asthma severity focuses on elimination of household smoking and the reduction of exposure to dust mite and cockroach microantigens in the environment. Wrapping mattresses with plastic casings, conversion of carpeted floors to tile floors, replacing drapes with blinds, and selecting home furnishings which avoid antigen accumulation, may result in improvement. Allergy testing and subsequent immunotherapy to desensitize a patient may be beneficial in some asthmatics. It is basically a chronic condition with biphasic components which both result in airflow obstruction by different means. The treatment should take into account the various triggering factors, occupation, age, psychosocial, and economic factors. Describe clinical findings signifying the severity of an acute asthma exacerbation. Discuss the approach to an asthmatic in relationship to formulating an acute asthma treatment plan. What questions do you ask, what physical findings do you look for, and what laboratory parameters are measured Describe various triggering factors and mechanisms by which they might exert their action. Describe the immunologic chain of events that ultimately leads to bronchospasm and inflammation. Discuss the pros and cons of corticosteroid use in children and compare them with use in adults. How would you convince parents of asthmatics to use medications when their children are not openly symptomatic Asthma is best thought of as a chronic inflammatory condition consisting of obstruction of the airways of the lung caused by spasms of the smooth muscle surrounding the airways which, in some cases, can be easily reversed by beta adrenergic bronchodilators. In other cases, corticosteroids may be necessary to reverse the airway obstruction by reducing the inflammatory changes responsible for the airway narrowing. Medications are divided into groups directed towards relaxing bronchial smooth muscles (relievers) and reversing the inflammation (controllers). The first is used to describe the degree of severity of the acute asthmatic episode. These would include rate and effort of respirations, ability to move air through a peak flow meter or spirometer, and oxygen and carbon dioxide concentration in the arterial blood. Day symptoms, night coughing episodes, peak flow, coughing with exercise, prolonged coughing after upper respiratory infections, and coughing with drinking ice-cold beverages help to categorize the severity of asthma. Wheezing may be heard but if the attack is very severe there may be no wheezing at all (due to poor air exchange). Evidence of respiratory distress (retractions, tachypnea) indicates increasing severity until respiratory failure occurs (at which point, the patient may tire and exhibit seemingly less respiratory distress). For mild cases, cough may be present at any phase of an asthmatic episode and may be the only sign that bronchospasm is occurring. A peak flow meter reading before and after a challenge of inhaled bronchodilator may reveal an increase in the airflow indicating the presence of bronchospasm. Preventive use of medications can be very useful such as preemptive use of medication with first sign of a cold. Use of the peak flow meter can serve as an objective means of adjusting medications. If cough and wheezing occur often and there are signs/symptoms of chronic asthma, a maintenance plan of daily medication should be initiated. This estimation can serve to guide you in the type and dosage of anti-inflammatory medications to use. A contingency plan of what medications to use during an acute episode can be helpful and may help to avoid an unnecessary emergency visit to the hospital. Regular monitoring with peak flow meter readings can help to determine if the treatment is helping to return the lungs to normal function. A "rescue" plan using short acting bronchodilators with optional systemic corticosteroids may be needed for breakthrough wheezing. Allergen exposure is mediated through IgE with resultant immediate and late phase reactions. A variety of mediators are released and cause a cascade of immunologic events culminating in tissue edema, increased mucous production, and sloughing of the epithelial layer of the inner lining of the airways. This affects the free and easy movement of air to the alveoli, which affects air exchange and causes atelectasis as the smaller air ways are completely plugged by the thickened mucous. Triggering mast cells cause release of mediators, which can cause immediate effects on the lung tissue and smooth muscles. Other mediators are formed and released later and serve primarily to attract inflammatory cells. Other mediators recruit epithelial cells and transform then into participants of the reaction causing them to release more mediators (biologic amplification). It is now well established that the use of inhaled steroids has significantly less effect on growth than systemic corticosteroids. The length of steroid use (inhaled or systemic), may have some effect on growth but its effect is temporary and in many studies final growth of asthmatics is generally no different than in non asthmatics. Chronic inflammatory suppression (long term use of inhaled corticosteroids) improves the long term outcome of asthma. You need to educate and persuade the parents that your recommendations are in the best interest of their child and that it is based on considering the risks against the benefits. This is ideally done without making the parents feel guilty or intimidated by the potential for fatal outcomes. For persistent asthmatics, they should be convinced that this is a chronic disease and long term medications will be required. He was the product of a 21 year old Gravida 2 Para 1, Ab 0 mother and was born at 41 weeks of gestational age. Soon after birth, he developed respiratory distress and was admitted to the neonatal intensive care unit where he was mechanically ventilated for 1 day and discharged after 5 days. He was initially breast-fed, but due to frequent vomiting and loose bowel movements, he was changed to formula feeding. At the age of 5 months he was hospitalized for respiratory distress and was diagnosed as having asthma. He continued to have loose, large, greasy, foul-smelling stools and failure to thrive. Family history: Mother (age 21), racially mixed Japanese, Chinese, English and Irish. Deep throat culture after coughing induced by respiratory therapy using a suction trap collection unit (specimen treated by laboratory as a sputum culture): Klebsiella pneumoniae. Cystic fibrosis mutation analysis (genetic testing): Positive for one copy of Delta F508 and one copy of R1066C. A series of events that took place during the very hot summer of 1938 in New York City led to the recognition of a new disease, cystic fibrosis. Dorothea Anderson (1) noted that a number of children presented to Columbia Hospital with severe dehydration, but without diarrhea or vomiting. The chloride values for patients with cystic fibrosis were elevated and a clear separation from normal volumes was found to exist. Similar elevations for sodium as well as potassium exist but there is greater overlap with the normal population. Historically, obtaining a sweat test involved bundling the child to induce sweating. Sometimes children were even placed near furnaces to make them sweat more profusely.
