    ABSTRACT: Adequate adherence to anti-retroviral therapy is required to achieve viral suppression and desirable treatment outcomes among HIV patients. The aim of this study was to examine the associations between adherence and severity of substance use as well as adherence and severity of depressive symptoms among Iranian HIV patients. In a prospective study, HIV patients with current substance use were assessed for adherence level via self report and pill count methods, severity of depressive symptoms (Beck Depression Inventory-II) and substance use (Addiction Severity Index) during a three months follow up after initiating anti-retroviral therapy. The adherence level, severity of depressive symptoms and substance use were assessed one month, two months and three months after initiation of anti-retroviral therapy. Addiction Severity Index (ASI) composite scores were calculated for each domain and the associations between ASI domains and adherence as well as severity of depressive symptoms and adherence were assessed. Twenty six HIV patients with current substance use disorder completed the study. At the end of the first month, adherence to therapy via pill count and self-report were 80%±31.9% and 85.12%±32%, respectively. At the end of the second month, adherence to therapy via pill count and self report were 87%±32% and 93.94%±23% respectively. At the end of the third month, the measured adherence via pill count and self report were 85%±33.7% and 90.1%±25.7% respectively. Adherence was higher among married patients and those who used reminder systems. Composite scores of the medical status and psychiatric status were related to higher adherence after first month. Substance use was inversely associated with adherence at the second follow up (r=-0.4, p=0.04). Also, severity of depressive symptoms was not related to adherence level. The repeated measurement analysis showed a significant decrease in psychiatric status domain of the ASI composite score after three months of initiating therapy (p=0.02). Preventive measures should aim treatment of substance use among HIV patients in order to increase adherence level. Also, conducting psychological evaluations is necessary considering the high prevalence of depression among Iranian HIV patients.ewer therapeutic agents like fosfomycin will add on to therapeutics for UTI's.

    ABSTRACT: Osteoprotegerin plays a critical role in the pathogenesis of atherosclerosis. Elevated osteoprotegerin concentrations have been reported in microvascular complications of diabetes. Patients with diabetes are at increased risk of macrovascular complications, particularly peripheral artery disease (PAD). To investigate the association between osteoprotegerin concentration and PAD in diabetes. In a cross-sectional setting, patients with type 2 diabetes for>5 years and no apparent diabetic foot ulcer were recruited. Patients underwent colour Doppler ultrasonography of lower limbs and were designated PAD+ if arterial narrowing was detected. Ankle-brachial index (ABI) was measured. Serum osteoprotegerin concentrations were determined. Ninety-eight patients (47 PAD+, 51 PAD-) were recruited. Osteoprotegerin concentrations (median [interquartile range]) were significantly higher in PAD+ versus PAD- patients (0.80 [0.50-1.95] ng/mL vs 0.30 [0.25-0.40] ng/mL; P<0.001). In logistic regression, log-osteoprotegerin was a predictor of PAD in univariate and multivariable analyses. In the final multivariable model, adjusting for age, sex, body mass index, smoking, hypertension, glycaemic control, lipid profile, renal function and C-reactive protein, one standard deviation increase in log-osteoprotegerin was associated with a more than twofold increase in the risk of having PAD (odds ratio 2.26, 95% confidence interval 1.50-3.40). In PAD+ patients, osteoprotegerin was a significant predictor of disease severity, determined by ABI and percentage of vessel occlusion in univariate and multivariable models. Osteoprotegerin concentrations are increased in patients with diabetes and PAD. Osteoprotegerin is an independent predictor of the presence and severity of PAD in diabetic patients.

    ABSTRACT: Obesity and its associated morbidities pose a major health hazard to the public. Despite a multiplex of available diet and exercise programs for losing and maintaining weight, over the past years, interest in the use of complementary and alternative medicine (CAM) for obesity treatment has greatly increased. We searched PubMed, Google scholar and the Cochrane databases for systemic reviews, review articles, meta-analysis and randomized clinical trials up to December 2013. In this review, the efficacy and safety of the more commonly used CAM methods for the treatment of obesity, namely herbal supplements, acupuncture, and non-invasive body-contouring, are briefly discussed. The evidence supporting the effectiveness and safety of these methods is either lacking or point to a negligible clinical benefit, barely surpassing that of the placebo. Furthermore, several limitations are observed in the available scientific literature. These shortcomings include, without being limited to, uncontrolled trial designs, non-random allocation of subjects to treatment arms, small number of patients enrolled, short durations of follow-up, and ambiguous clinical and laboratory endpoints. Further investigations are necessary to accurately determine the efficacy, safety, standard dosage/procedure, and potential side effects of the various CAM methods currently in use.

    ABSTRACT: The constellation of metabolic abnormalities seen in the metabolic syndrome (MetS) has been linked to atherosclerosis and adverse cardiovascular outcomes due to heightened inflammation. Accumulating evidence suggests that peripheral 5-Hydroxyindole-3-Acetic Acid (5-HIAA), the derivative end-product of serotonin, might be involved in the pathogenesis of obesity, and abnormal lipid and glucose metabolism. We examined the association between serum 5-HIAA concentrations and MetS and also highly sensitive C-reactive protein (hsCRP). In a cross-sectional setting, 180 healthy adults (110 males and 70 females) were included. Anthropometric indices and blood pressure were measured and laboratory parameters including fasting concentrations of 5-HIAA were determined. The associations between 5-HIAA and individual components of MetS, as well as MetS as a single entity, were investigated with bivariate correlation and logistic regression. Eighty-nine individuals (49.4%) were diagnosed with MetS. Significant correlations between 5-HIAA concentrations and age (r=0.184), waist circumference (r=0.415), HDL cholesterol (r=-0.148), systolic blood pressure (r=0.374), diastolic blood pressure (r=0.355), homeostasis model assessment of insulin resistance (r=0.201), and hsCRP (r=0.453) were found (p<0.05 in all tests). In logistic regression, 5-HIAA was significantly associated with four components of MetS including central obesity, raised triglycerides, raised blood pressure, and raised fasting plasma glucose (p<0.05). Moreover, 5-HIAA was a predictor of MetS as a single entity, and the relationship persisted after adjusting for hsCRP (OR=4.41, 95% CI: 2.58-7.67, p<0.001). Elevated concentrations of 5-HIAA are seen in individuals with MetS. Increased 5-HIAA is also associated with hsCRP, a marker of chronic low grade inflammation underlying MetS.

    ABSTRACT: Purpose: To present a new approach for management of cutaneous vesicostomy (CV) prolapse, with special emphasis on normal appearing vesicostomy may be malfunctioning. To introduce the application of temporary stoma-free drainage as a diagnostic and therapeutic tool. Materials and methods: From December 2000 to September 2006, 66 children (61 males and 5 females) with CV were studied. The mean age at vesicostomy was 7 months (range 1-30), and the main underlying disease was posterior urethral valves (in 45 children, 68%). Indications for CV included significant hydroureteronephrosis (HUN) and recurrent urinary tract infection. Patients were followed up for complications and were treated based on our institutional approach. All patients with persistent upper tract dilatation and micturition per urethra underwent temporary bladder (via stoma) free drainage. Patients with stomal stenosis were managed either by a revision surgery or by simple dilatation and intermittent catheterization. Purse string suturing was applied in mucosal prolapses as the first choice. Results: The complications were observed in 21 patients (31%), including twelve stomal stenosis, nine severe mucosal prolapses, and two recurrent urinary infections. HUN and significant voiding per urethra persisted following initial CV in 19 out of 66 patients (29%), eleven of which having normal appearing CVs. Seventeen of these patients were managed by temporary stoma-free drainage (accompanied by purse string suturing in mucosal prolapse), and two patients with severe stenosis underwent surgical revision. Temporary stoma-free drainage improved HUN in 94% of patients (16 of 17). Conclusions: Voiding per urethra is an indicator of CV malfunction, and temporary stoma-free drainage can be a diagnostic and therapeutic option in such children. A seemingly open CV may still be malfunctioning, and ureterovesical or intravesical obstructions should be considered if HUN does not improve following temporary stoma-free drainage.

    ABSTRACT: Complete urethral duplication is a rare congenital genitourinary anomaly with various symptoms. Since anatomical place of urethra greatly varies between cases, surgical management of the patients is personalized according to the type of the duplication and requires a careful workup before planning for any intervention. In this case report, a 4-year-old boy with finding of complete proximal hypospadiac urethral duplication is presented with double-stream voiding. He was passing a normal stream of urine through the hypospadiac tract, while a thin stream came out from the normal meatal site. Examination revealed a hypoplastic orthotopic urethra with an accessory penoscrotal hypospadiac urethra. The patient was successfully managed with hydrodistension technique which was used to resolve the stricture of hypoplastic dorsal urethra followed by end-to-end anastomosis to penoscrotal hypospadias. This approach gives an insight that the technique could be possibly considered as a simple alternative to avoid proximal hypospadias repair which is comparatively a challenging surgical task.

    ABSTRACT: To report the results of endoscopic correction of vesicoureteral reflux (VUR) with concomitant injection of pure calcium hydroxyapatite (CaHA) and autologous blood. Records of patients who underwent endoscopic correction of VUR using concomitant injection of CaHA and autologous blood from 2008 through 2010 were retrospectively reviewed. Data regarding patients' demographics, preoperative VUR grades, febrile urinary tract infections, complications of procedure, postoperative VUR grades and cure rates were collected. Voiding cystourethrography was performed 3 months postoperatively. Total number of 23 children (9 girls and 14 boys) with 40 refluxing ureters were included. The mean age of children was 1.9 ± 0.97 (SD) years. Reflux grades were II to IV in 14, 11 and 15 renal refluxing units (RRUs), respectively. The mean follow-up period was 44 months. VUR was successfully treated in 87.5 % of RRUs after three injections. Significant statistical difference was found between VUR grades before and after the first, second and third injections (p < 0.001, p = 0.001 and p = 0.011, respectively). Moreover, there was a significant difference between primary reflux grade and treatment success (p = 0.031). Febrile UTI was resolved in 85 % of patients (17 of 20 patients with febrile UTI) after endoscopic treatment which shows significant improvement (p < 0.001). The procedure was uneventful in all patients, and no obstruction was reported during the follow-up period. Concomitant injection of pure CaHA without any additives (hyaluronic acid, etc.) and autologous blood can be an effective, repeatable and cost-benefit approach for the management of children suffering VUR with a success rate of 87.5 % after three injections.

    ABSTRACT: To investigate the feasibility of biodegradable plate and screws for the tension-free internal fixation of the symphysis pubis in patients with bladder exstrophy, with a particular emphasis on pelvic bone changes as seen on 3-dimensional computed tomography. A total of 11 children with bladder exstrophy underwent surgical repair with biodegradable plate and screw fixation (mean age 4.13 years). Of the 11 patients, 6 had a history of failed bladder closures and pelvic osteotomies, 1 had failed bladder closure, and 4 had no such history. All 11 children underwent single-stage classic bladder closure. Subsequently, the symphysis pubis was fixed by placing a biodegradable miniplate and screws. The patients remained in leg bandages for 2 weeks. The follow-up period was 6-50 months (average 30.1). Three-dimensional pelvic bone computed tomography was performed initially and at 6 months postoperatively. All 11 children had an uneventful postoperative period, except for a superficial infection at the site of the suprapubic tube in 1 patient. The mean hospital stay was 13.4 days. The plate remained in situ, and no further surgery was needed to remove it. Pelvic 3-dimensional computed tomography revealed a 35.48 ± 1.50 mm, 20.06 ± 1.97 mm, and 10.73° ± 0.84° decrease in pubic diastasis, intertriradiate distance, and iliac wing angle at 6 months postoperatively, respectively. Significant improvement was seen in the patients' urinary continence and gait compared with the preoperative values. At the final follow-up visit, 6 patients were socially dry. Internal fixation of the pubic arch using biodegradable plates as a biocompatible alternative to current metal fixation system offers intriguing potential for early exstrophy management. This adds a layer of security to the pubic closure, in addition to the current surgical armamentarium for bladder exstrophy.
