Direct comparisons Beclomethasone compared with fluticasone The only head-to-head evidence in children and adolescents with perennial allergic rhinitis comes from a meta-analysis of combined data from a smaller (N=120) 12-week head-to- head trial comparing fluticasone 100 mcg once or twice daily with beclomethasone 200 mcg twice daily and a larger (N=415) 4-week placebo-controlled trial, which compared fluticasone 80 100 mcg or 200 mcg once daily with placebo. There is no specific data reported for the comparator study, only the statement that fluticasone was as effective as beclomethasone in increasing the median percent of symptom-free days for all symptoms. Indirect comparisons: Placebo-controlled trials Since there was only 1 head-to-head comparison study involving children or adolescents that met review criteria, we looked at the available evidence from 10 placebo-controlled trials 81-90 (Evidence Tables 7 and 8; Table 13). Due to the heterogeneity of this evidence, no indirect comparisons of efficacy in children were possible. A recent Cochrane review of placebo-controlled trials that included 3 older studies (Hill, Neuman, and Sarsfield; see Table 13 below) concluded that beclomethasone and flunisolide were 91 likely more effective than placebo based on the very limited evidence available. No trials in children of the 2 new drugs included in this update (ciclesonide and fluticasone furoate) were identified. One published abstract of a 12-week placebo-controlled trial of fluticasone furoate in children aged 2 to 11 years was identified through the dossier provided by the drug’s manufacturer. The limited results presented suggest that the 55µg dose is significantly better than placebo at reducing the nasal symptoms associated with perennial 92 allergic rhinitis based on reflective TNSS. Placebo-controlled trials in children/adolescents with perennial allergic rhinitis Interventions Mean age Study (Total daily dose) Age range Sample size Duration % female Outcome Results 13. Direct comparisons There were no head-to-head efficacy trials that compared any nasal corticosteroids in adults with perennial non-allergic rhinitis that met the inclusion criteria of this review. Indirect comparisons in placebo-controlled trials We found 2 placebo-controlled studies of patients with non-allergic rhinitis that were not indirectly comparable due to heterogeneous efficacy outcome reporting (Evidence Tables 9 and 10). The first study of fluticasone reported efficacy for use in non-allergic rhinitis and the second 93, 94 study of mometasone revealed mixed results in this population. A pooled analysis from 3 randomized, double-blind, double-dummy, placebo-controlled trials examining fluticasone aqueous 200 mcg and 400 mcg compared with placebo in 983 patients with non-allergic rhinitis (NARES) and without eosinophilia (non-NARES) reported 93 clinical improvement of symptoms in the total population. Both doses of active drug showed significant improvement in total nasal symptom score (100-point visual analog scale for individual symptoms, maximum possible 300) after 4 weeks compared to placebo, -84, -85, and - 64 for the lower dose, higher dose, and placebo respectively, P<0. Differences for the individual subgroups, non-NARES and NARES, also favored active drugs, but did not report significance. The fair quality multicenter, randomized, double-blind, placebo-controlled trial investigating mometasone 200 mcg found mixed results for the efficacy in 329 adult patients 94 with non-allergic rhinitis. The patient-rated improvement was numerically greater for mometasone than placebo, 56% compared with 49%; however this difference was not significant. The secondary efficacy variable of investigator-rated improvement was significantly greater for mometasone compared to placebo, 60% compared with 48% (P=0. Efficacy was reported as improvement rate, which was defined as reduction of at least 1 point in overall symptom score, comprising 4 individual symptoms on a 4-point scale for a maximum total of 12 points. The study also reported no significant difference in quality of life, but did not report methods or specific results. Based on the results of 2 unpublished studies provided by the drug’s manufacturer, fluticasone furoate was not significantly better than placebo at improving daily reflective TNSS 95, 96 in patients with non-allergic rhinitis triggered by changes in weather or temperature. Likewise, there was no significant difference in response to therapy between fluticasone furoate and placebo in either study. Full, published results of these studies were not identified through literature searches. Children No efficacy trials of nasal corticosteroids in children with perennial non-allergic rhinitis were identified. NCS Page 32 of 71 Final Report Update 1 Drug Effectiveness Review Project Key Question 2. For adults and children with seasonal or perennial (allergic and non-allergic) rhinitis, do nasal corticosteroids differ in safety or adverse events? Direct comparisons Head-to-head trials served as the primary source of evidence for comparisons between nasal corticosteroids in incidence and severity of the more common adverse effects associated with shorter-term usage. No head-to-head trial was of sufficient duration to measure comparative risk of cataract development or worsening of glaucoma. Rates of withdrawals due to adverse events, headache, throat soreness, epistaxis, and nasal irritation were generally similar between nasal corticosteroids in head-to-head trials of adults/adolescents with either seasonal or perennial 12-21, 23-27, 29, 50-54, 56-59, 94, 97-100 rhinitis (Appendix E). One exception is that the old formulation of flunisolide 200 or 300 mcg was associated with significantly higher rates of nasal burning/stinging than beclomethasone AQ 168 or 336 mcg (30% compared with 33% compared 26 with 10% compared with 10%; P<0. It is not yet clear how the new formulation of flunisolide 200 mcg ranks relative to other nasal corticosteroids with regard to nasal irritation effects. To-date, nasal burning/stinging rates associated with the new formulation of flunisolide have only been directly compared to the discontinued form of beclomethasone (20% compared with 2.

A wide variety of topics are addressed in this chapter, including fertility, gonadal failure, erectile dysfunction, and menstrual issues in SCD. Etiologies of impaired male fertility are multifactorial and include hypogonadism, erectile dysfunction, sperm abnormalities, and complica- tions of medical therapies. Much less is known about the prevalence and etiology of infertility in women with SCD. Other reproductive issues in women included in this review are pain and the menstrual cycle, contraception, and preconception counseling. Finally, long-term therapies for SCD and their impact on fertility are presented. Transfu- sional iron overload and gonadal failure are addressed, followed by options for fertility preservation after stem cell transplantation. Focus is placed on hydroxyurea therapy given its benefits and increasing use in SCD. The impact of this agent on spermatogenesis, azoospermia, and the developing fetus is discussed.

The absolute change was not reported and again the data were reported to be skewed purchase lamisil 250mg on-line. A study of solifenacin 5 mg or 10 mg once daily and immediate-release tolterodine 2 mg twice daily demonstrated that both doses of solifenacin and tolterodine produced significantly 50 lower mean frequency of micturition than placebo cheap lamisil 250mg. Solifenacin at both doses order lamisil 250 mg otc, but not tolterodine, resulted in statistically significant improvements in urge and number of incontinence episodes per 24 hours and episodes of urgency. Only solifenacin 10 mg was better than tolterodine for reducing frequency of micturition. Patients administered solifenacin had significantly decreased urgency, incontinence, urge 28 incontinence, and pad usage. However, the study did not demonstrate statistically significant between-treatment differences in the primary endpoint, frequency of micturition, or in nocturia episodes, thus solifenacin was non-inferior to extended-release tolterodine for these measures. Data for both doses of solifenacin were combined for analysis of outcomes. A post hoc analysis of only solifenacin 5 mg and extended-release tolterodine 4 mg in the initial 4 weeks of the STAR trial showed a significantly greater mean reduction in number of 106 incontinence episodes per 24 hours for solifenacin (–1. A head-to-head trial used a crossover design to compare darifenacin (15 mg or 30 mg once daily) with immediate-release oxybutynin (5 mg 3 times daily). Darifenacin (both doses) and oxybutynin were significantly better than placebo for reducing the number of incontinence episodes per day and reducing the frequency of micturition, but no significant difference in 105 efficacy was found between the drugs. Symptoms and overall assessment of benefit Short-acting compared with long-acting drugs One study comparing immediate-release oxybutynin with extended-release tolterodine in 36 Japanese and Korean women assessed subjective outcome measures. Patients were asked to Overactive bladder Page 27 of 73 Final Report Update 4 Drug Effectiveness Review Project assess their perception of bladder condition (on a 6-point scale), urinary urgency (on a 3-point scale), overall treatment benefit (on a 3-point scale), and quality of life (measured by the King’s Health Questionnaire) at baseline and 12 weeks. There was no difference between the groups based on the change in the patients’ perception of bladder condition (improved, extended-release tolterodine 72% compared with immediate-release oxybutynin 73%; the deterioration rate for both treatments was 5% and was 8% for placebo). The patients’ assessment of urinary urgency was also similar between the groups (improved ability to hold urine, extended-release tolterodine 49% compared with immediate-release oxybutynin 57%). The treatment benefit was rated “much” by 42% on extended-release tolterodine compared with 53% on oxybutynin. Although both treatments showed a difference in quality of life compared with placebo, no significant differences between treatments were found in any domain of the quality-of-life assessment. Perception of Bladder Condition is a validated 6-point categorical scale used by patients. A decrease in score signifies improvement in perceived bladder condition. While the difference between drugs was statistically significant (P=0. The post hoc analysis of solifenacin 5 mg and tolterodine 4 mg in only the initial 4 weeks of the STAR trial found a significantly greater mean reduction in pad use for solifenacin (–1. The remaining efficacy outcomes included frequency of micturition, incontinence, and nocturia and showed no significant difference between the 2 drugs at 12 weeks. The head-to-head trial that compared darifenacin (15 mg or 30 mg once daily) with immediate-release oxybutynin (5 mg 3 times daily) found no significant difference in reductions 105 of mean severity of urgency episodes between the drugs. For adult patients with urinary urge incontinence/overactive bladder, do anticholinergic incontinence drugs differ in safety or adverse events? Long-term studies No long-term head-to-head studies assessed adverse events associated with tolterodine, 34 darifenacin, solifenacin, or flavoxate. We found 1 head-to-head study comparing adverse events for trospium and oxybutynin over an average of 54 weeks (mean follow-up). This study compared trospium 20 mg twice daily with oxybutynin immediate-release 5 mg twice daily. Significant differences were found favoring trospium for adverse events taken as a whole, adverse events having probable or possible connection with trial medications, and for dryness of the mouth. Subjective appraisal of tolerability also favored trospium at 26 and 52 weeks. Overall rates of adverse events were high in both groups (65% for trospium and 77% for oxybutynin). We found 3 studies of prescription claims data that evaluated the discontinuation rate of 108-110 new prescriptions for tolterodine or oxybutynin (see Evidence Table 8). One study evaluated the proportion of patients discontinuing treatment (not refilling prescription) in a 6- 108 month period in 1998. Thirty-two percent of patients who were prescribed tolterodine, Overactive bladder Page 28 of 73 Final Report Update 4 Drug Effectiveness Review Project compared with 22% on oxybutynin, were still refilling their prescriptions at 6 months (P<0. The mean time to discontinuation was 59 days for tolterodine and 45 days for oxybutynin; 55% on tolterodine never refilled the original prescription compared with 68% on oxybutynin.

RECTO-VAGINAL FISTULA A recto-vaginal fistula is only produced in the most prolonged episodes of obstruction and so is usually associated with a bad vesico-vaginal fistula and neurological damage. Isolated recto-vaginal fistulae due to obstructed labor are extremely rare but may be caused by sexual violence in war situations or in underage marriage. Anal sphincter tears usually occur in isolation unrelated to obstructed labor and should not be classified as a recto-vaginal fistula unless there is sig- (h) nificant extension into the rectum. Incompletely repaired sphincter tears are another source of low recto-vaginal fistulae. Classification is largely des- criptive, based on the distance from the anal verge and the amount of scar. When scar is prominent the rectal lumen can be considerably narrowed. In extreme cases the rectum is completely stenosed and all the feces enter the top of the vagina. Surgery is demanding and except for the lowest and most mobile should be referred to fistula experts. It has been tradition in some quarters to con- sider doing a colostomy for the bad cases before referring the patients. This does not make life any easier for the patient and experienced surgeons can repair the majority of rectal fistulae transvaginally without any preliminary colostomy. A more likely (i) scenario is that a well-meaning surgeon does a colostomy but the patient never finds a surgeon who can repair her fistula (Figure 22a). When colostomies are inexpertly done a colostomy pro- lapse may develop to add to her misery. The only person who should consider performing a colos- tomy is the surgeon who is going to repair her fistula. The principles in repairing a recto-vaginal fistula are the same as for a vesico-vaginal fistula – good exposure, flap splitting of vagina from rectum, followed by closure of the rectum in two layers (Figure 22). Most surgeons will repair the bladder and rectal fistula at the same time although for really bad cases Figure 21 (cont) (g) The rectum is closed with a the recto-vaginal fistula may be repaired alone as continuous suture down to the anal verge previously the first stage.
