A rare case of extraperitoneal gastrointestinal stromal tumor arising from kidney.

Mesenchymal tumors of the gastrointestinal tract which arise from the interstitial cells of Cajal and express C-Kit protein or CD117 on immunohistochemistry are known as gastrointestinal stromal tumors (GISTs). Extraperitoneal GISTs (EGISTs) are rare tumors arising from the mesentery, omentum, or retroperitoneum. We report a case of a 52-year-old male who presented with a huge abdominal lump arising from the right renal capsule that was found to be EGIST on histopathological examination and immunohistochemistry.

Tadalafil improves erectile dysfunction and quality of life in men with cirrhosis: a randomized double blind placebo controlled trial.

BACKGROUND AND AIMS: Patients with cirrhosis have high prevalence of erectile dysfunction (ED). The aim of this study was to study the efficacy and safety of tadalafil for ED in patients with cirrhosis. METHODS: 140 cirrhotic males with ED were randomized into tadalafil 10 mg daily (n = 70) or placebo (n = 70) for 12 weeks. ED was diagnosed if erectile function (EF) domain score was < 25 in International Index of Erectile Function (IIEF) questionnaire. The erectile function domain consists of six questions concerning erection frequency, erection firmness, frequency of partner penetration, frequency of maintaining erection after penetration, ability to maintain erection to completion of intercourse and confidence in achieving and maintaining erection. Primary outcome was proportion of patients having an increase in > 5 points in EF domain of the IIEF. Generalized Anxiety Disorder 7 (GAD-7) questionnaire was used for screening and severity measuring of GAD. The presence of depression was screened using the Patient Health Questionnaire (PHQ-9) and the assessment of health related quality of life was done using the Short Form (36) Health Survey. RESULTS: At the end of 12 weeks, more patients in tadalafil group achieved > 5 points increase in the EF domain of the IIEF when compared with the placebo group [44(62.9%) vs. 21(30%), p < 0.001]. At the end of 12 weeks, patients receiving tadalafil had significantly more change in scores on the erectile function domain, orgasmic function domain, intercourse satisfaction domain, overall satisfaction domain, erection vaginal penetration rates and successful intercourse; significantly more decline in the GAD-7 and PHQ-9 scores; significantly more improvement in scores of five of the eight domains of SF-36 (general health perception, vitality score, social functioning, role emotional and mental health) and the mental component summary rates when compared with placebo. The development of side effects and the changes in HVPG were not significantly different between the two groups. CONCLUSIONS: Tadalafil therapy may enhance erectile function, improve anxiety, depression and quality of life; and is well tolerated by men with cirrhosis (CTP score < 10) and ED. However, further larger and long-term studies are needed to confirm these results and look for rarer side effects of using tadalafil in patients with cirrhosis.

Erectile Dysfunction in Cirrhosis: Its Prevalence and Risk Factors.

Background: Erectile dysfunction (ED) is common in men with cirrhosis. The aim of this study was to assess the prevalence of ED and the factors associated with ED in men with cirrhosis. Methods: 400 men with cirrhosis [Child-Turcotte-Pugh (CTP) class A, 44.0%; CTP class B, 41.0%; and CTP class C, 15.0%] having high Karnofsky performance score, and living in a stable monogamous relationship with a female partner were included in the study. International Index of Erectile Function (IIEF) questionnaire, and Short-Form (36) Health Survey (SF-36) were used to assess erectile function and the health-related quality of life (HRQOL), respectively. Results: ED was found in 289 (72.3%) patients. Patients with ED reported significantly lower SF-36 scores across all the eight domains of SF-36 (i.e., physical functioning score, role physical score, bodily pain score, general health perception score, vitality score, social functioning score, role emotional score, and mental health score); physical component summary score, and mental physical component summary score, compared with those without ED. On multivariate analysis, factors associated with ED were older age, longer duration of cirrhosis, CTP-C (vs. CTP-A), higher hepatic venous pressure gradient (HVPG), presence of generalized anxiety disorder (GAD), presence of major depression, and lower appendicular skeletal muscle index measured by dual-energy X-ray absorptiometry (DEXA ASMI). Conclusion: ED is common in men with cirrhosis, and men with ED have poor HRQOL compared with those without ED. Older age, longer duration of cirrhosis, CTP-C (vs. CTP-A), higher HVPG, presence of GAD, presence of major depression, and lower DEXA ASMI are associated with ED.
