Stimulant laxatives are commonly used, but questions remain about the development of neuronal degeneration with prolonged usage. Data regarding laxative use for this condition have failed to show a significantly better response than placebo. Currently there is only one available prokinetic agent, tegaserod, approved for the treatment of constipation that improves colonic transit. They have not been shown to have greater efficacy when compared with placebo, and their role in the treatment of dyssynergic defecation remains uncertain. Specific treatment for this condition tends to focus on biofeedback because of studies indicating that this is an acquired behavioral disorder of defecation. Modalities such as diaphragmatic muscle training, simulated defecation, and manometric or electromyography-guided anal sphincter and pelvic muscle relaxation have been employed independently or combined with other techniques. These techniques have yielded symp to matic improvement in approximately 60% to 80% of patients. Many patients with dyssynergic defecation also have abnormal rectal sensation, so rectal sensory conditioning may provide additional benefit (33,49,169,170). Others have tried botulinum to xin injections to paralyze the puborectalis and anal sphincter muscle. Small case series have shown modest early improvement, but the results do not appear to be long lasting (171,172). A recent randomized trial of 48 participants comparing botulinum to xin to biofeedback retraining found better initial improvement with the botulinum to xin (70% vs. Pessary for Treatment of Pelvic Organ Prolapse Pessaries of various shapes and sizes have been used for centuries to treat pelvic organ prolapse (174). They are a safe alternative to surgery, with the most common complications being increased vaginal discharge and erosion or ulceration of the vaginal wall. Although pessaries represent a common therapeutic modality, there are limited data regarding fitting and management (175). Even less is known about which type of pessary is better for enteroceles and rec to celes, although the site of prolapse does not appear to affect the ability to retain a pessary (176). Some of the space-occupying pessaries, such as the Gellhorn and cube, use a suction mechanism to maintain vaginal retention, whereas others, like the donut, do not. In theory, space occupying pessaries and those that exert forces against the posterior wall and vaginal apex (donut, inverted Gehrung) should aid in treatment of rec to celes and enteroceles. However, there are few data regarding the efficacy of pessaries for relieving symp to ms of disordered defecation. The only randomized crossover trial comparing different types of pessaries (ring and Gelhorn) found improvement in quality-of-life measures with each pessary that did not differ.

Although low pressures are preferred in the dialysate side of the system 195 ( to promote ultrafiltration), increasing the dialysate pressure could reduce the filtration rate in desired circumstances Blood priming Blood priming refers to filling the circuit volume with blood prior to its connection to the patient circulation. It is particularly needed when the circuit volume exceeds 10-15% of the estimated blood volume of the child. Heparin is given continuously at a rate of 10-20 units/kg/h after a bolus of 20-30 units/kg. Sodium citrate is delivered to the initial part of the circuit providing a local anticoagulation effect. Citrate is converted to bicarbonate in the liver which could cause metabolic alkalosis. Be careful in patients with hepatic insufficiency because citrate overload could cause metabolic acidosis. Conversion of lactate to bicarbonate in the liver limits the use of lactate based solutions in 196 patients with associated liver impairment. Furthermore, due to its vasodila to r properties and non-physiologic pH, lactate could cause hypotension and worsen acidosis due to accumulation of lactate. The lack of urea and other non-desired metabolic byproducts in the dialysate solution creates a concentration gradient by which these solutes are cleared from the blood. High concentrations of urea, potassium and phosphorus in blood of patients with renal failure are easily eliminated through the membrane both by convection (ultrafiltrate) and diffusion (low or physiologic concentrations in the dialysate solution). Bicarbonate-based fluid is preferred over lactate-based due to the risk of metabolic acidosis leading to cardiac dysfunction, vasodilatation, and hypotension. Albumin can be added to the dialysate fluid to help eliminate protein bound drugs. Circuit flow rate Blood flow (Qb) should be started below the goal rate and advanced to maximum rate over 30 min. Flow rates vary from to 10-12 mL/kg/min in neonates and 2-4 mL/kg/min in older children and adolescents. Low arterial pressures may be due to hypotension, kinks in the tubing system, catheter malfunction or stenosis of the arterial inflow. Venous hypertension may be due to clotting of the dialyzer/membrane, kinks in the tubing system or stenosis of the venous outflow. Neonates and children up to 6 kg usually require 7 Fr, 6 to 15 kg require 8 Fr, 15 to 30 kg require 9 Fr and >30 kg 10 Fr catheters. Determinations of daily urea clearance are derived by the following formula: Daily to tal Kt/Vurea = peri to neal Kt/Vurea + renal Kt/Vurea Where: K=clearance of urea, t=time (min), V=volume of distribution Adequate dialysis is a term employed to describe the effects of a dialysis dose by returning the patient with renal failure to almost physiologic parameters of kidney function and keeping him/her asymp to matic. Optimal dialysis is used to describe the reduction in morbidity and/or mortality with a determined dose of dialysis keeping in mind the financial burden or excessive workload if the dose is increased. Proteinuria (more specifically albuminuria), which is determined by the ratio of the concentration of albumin to creatinine in spot urine. Protein content in urine varies at different times of the day and proteinuria has been reported as high as in 10% of normal children but only less than 1% of these have persistent proteinuria.

These disorders are generally among the most easily diagnosed and treatable causes of infertility. Tubal and peri to neal fac to rs account for 30% to 40% of cases of female infertility. Cervical fac to r is estimated to be a cause of infertility in no more than 5% of infertile couples. Uterine pathologies constitute the etiologic fac to r in infertility in as many as 15% of couples seeking treatment and are diagnosed in as many as 50% of infertile patients. Multiple gestation, especially higher-order multiple gestation, is a serious complication of infertility treatment and has tremendous medical, psychological, social, and financial implications and complications. Fortunately, recent studies have not shown an increased risk for breast, uterine, or ovarian cancer secondary to medications used for superovulation in the treatment of infertility. Infertility is defined as 1 year of unprotected intercourse without pregnancy (1). This condition may be further classified as primary infertility, in which no previous pregnancies have occurred, and secondary infertility, in which a prior pregnancy, although not necessarily a live birth, has occurred. About 90% of couples should conceive within 12 months of unprotected intercourse (2). Subfertility refers to couples who conceive after 12 months of attempted impregnation (2). Fecundability refers to the probability of pregnancy per cycle, which is considered to be at 20% in fertile couples (1). Fecundity refers to the probability of achieving a live birth in a single cycle and, by definition, has a value lower than fecundability. Epidemiology Twenty-one percent of couples in the United States are expected to experience infertility in their lifetimes, with a current prevalence of 7. The diagnosis of impaired fecundity has been rising, reaching 15% in 2002 and largely resulting from the trend to ward delayed childbearing in developed countries (3). In Europe, ovula to ry dysfunction accounts for 21% to 32%, male fac to r 19% to 57%, tubal fac to r 14% to 26%, unexplained 8% to 30%, endometriosis 4% to 6%, and combined male and female fac to rs 34. The odds of infertility increase with female age and in general among patients who have not graduated from college (14). The high cost of infertility treatment is a barrier for many in the United States where insurance typically does not cover these services (15). Language and other cultural barriers affect access for many minority groups (15,16). The women most likely to obtain specialized treatment are 30 years of age or older, white, married, and of relatively high socioeconomic status (7).

The team will subsequently develop interventions that can affect one or several of the key drivers and lead to successful change to achieve the aim. Interventions to be tested should be specifically defined including how to measure compliance and what outcome to measure to determine success. Providing feedback to the involved staff will raise awareness about the intervention and lead to 491 self-driven motivation for improvement. Understanding reasons for non-compliance may identify barriers to implementation that need to be addressed or parts of the pro to col that may need to be adjusted. Simple checklists completed at the bedside can be used to collect data on intervention compliance [37]. This is typically achieved by providing continuous feedback to improve compliance with the intervention and either adjusting the intervention or adding a new intervention if maximum compliance with the initial intervention has been obtained. Successful adoption and maintenance of an intervention in to practice will establish new baseline levels or rates for the measured outcome.
