ABSTRACT
Diabetes insipidus (DI) is a condition with heterogeneous clinical symptoms characterized by polyuria (urine output >4 mL/kg/hr) and polydipsia (water intake >2 L/m (2)/d). In children, acquired nephrogenic DI (NDI) is more common than central DI (CDI). Diagnosis is based on the presence of high plasma osmolality and low urinary osmolality with significant water diuresis. A water deprivation test with vasopressin challenge, though has limitations, is done to differentiate NDI from CDI and diagnose their incomplete forms. Neonates and young infants are better managed with hydration therapy alone. Older children with CDI are treated with desmopressin (1-deamino-8-D-arginine vasopressin, dDAVP). Its oral form is safe, highly effective and has dosing flexibility. We report a case of an 8-year-old male patient with CDI with severe bilateral non-obstructive hydronephrosis and megaureter. Dramatic clinical and radiological responses to dDAVP treatment were achieved and therapy reduced urine volume and led to marked radiological improvement in hydronephrosis.
ABSTRACT
OBJECTIVE: To determine the relationship between erectile dysfunction and metabolic syndrome (MetS) in patients with benign prostatic hyperplasia (BPH) and lower urinary tract symptoms (LUTS). MATERIAL AND METHODS: Seventy-eight patients who were admitted to our outpatient clinic because of BPH-related LUTS over 40 years of age were included in the study. Patients with LUTS and erectile dysfunction (ED) were evaluated by International Prostate Symptom Score (IPSS) and International Index of Erectile Function-5 (IIEF-5) forms. The National Cholesterol Education Program Adult Treatment Panel III criteria was used for the diagnosis of MetS. LUTS were classified as mild, moderate, and severe according to IPSS and ED was classified as mild- moderate, moderate, and severe according to the IIEF-5. For the evaluation of data, descriptive statistical methods (mean, standard deviation, median, frequency, ratio, minimum, and maximum) and also for the comparison of the variables with non-normal distribution in 3 or more than 3 groups Student's t test, Mann-Whitney U, ANOVA, chi-square, Fisher Exact tests, and Pearson correlation analysis were used. P<0.05 was accepted as the level of statistical significance. RESULTS: Mean age of the patients included in the study was 61.83±9.15. In 34.6% of the patients with MetS, 70.5% of the patients with ED and 37.2% of the patients with severe LUTS were determined. There were no significant differences between the mean age of patients with and without metabolic syndrome (p>0.05). There was a positive correlation with age and severity of LUTS but this relationship was not found to be statistically significant (p>0.05). Mean age of the patients with ED was significantly higher than those without (p<0.001). A statistically significant relationship was not observed between the mean IPSS scores and the severity of LUTS with Mets. However, we observed a weakly positive correlation between triglyceride levels and IPSS. Mean IIEF-5 scores of the patients with MetS were significantly lower than those of the patients without MetS. Severity of ED in the patients with MetS was significantly higher than patients without MetS. The percentage of ED in patients with severe LUTS was found to be statistically higher than other patients with mild, and moderate LUTS. In addition, we found a low degree of negative correlation between IPSS and IIEF-5 scores. CONCLUSION: In patients with LUTS as a consequence of BPH, when severity of symptoms increases, frequency of MetS increases proportionally and severe ED is observed much more frequently.
ABSTRACT
PURPOSE: Although many virulence factors have been defined for Helicobacter pylori (HP), vacuolating cytotoxin A (VacA) is known to be associated with apoptosis, the cag pathogenicity island protein (Cag-PAI), and growth factors. Both apoptosis and growth factors are thought to be related to the etiology of benign prostatic hyperplasia (BPH). Additionally, the relation between atherosclerosis-BPH and atherosclerosis-HP has also been reported in a limited number of studies. The aim of this pioneering study was to investigate the presence of HP in BPH patients who had undergone transurethral resection of prostate (TURP) and to discuss the potential pathophysiologic effects of HP on BPH. MATERIALS AND METHODS: A total of 113 cases who underwent TURP due to infravesical obstruction due to BPH were included in the study. Preoperatively, parameters including, age, height, body weight, body mass index (BMI), prostate specific antigen (PSA), prostate volume (PVo), maximum urinary flow rate (Qmax), fasting plasma insulin, and International Prostate Symptom Score (IPSS)values were evaluated. The presence of HP was investigated in the prostate specimens with real-time polymerase chain reaction (RT-PCR) method. Postoperatively, histopathological evidence of chronic prostatitis (hCP) was also analyzed. RESULTS: HP was detected in 1.8% (n = 2) of the participants. Additionally, hCP was observed in 58.4% (n = 66) of the 113 patients. The demographic and clinical parameters confirmed the presence of BPH disease. CONCLUSION: Although BPH is a common disease, its physiologic etiology mechanisms are not clear. Based on our pilot study, despite its gastric location, we believe that HP should be considered in cases with clinical BPH because HP induces apoptosis and alterations in the equilibrium between apoptosis and local growth factors in addition to its recently demonstrated extragastric effects mediated via the atherosclerotic pathway. Although our uncontrolled pioneer study was not designed to investigate the pathophysiologic mechanism, the isolation of HP from prostatic adenoma suggests the need for further well-designed studies on this topic.
