Prevalence and risk factors for female sexual dysfunction in women attending a medical clinic in south India

BACKGROUND Reports from India on the prevalence and determinants of female sexual dysfunction (FSD) are scant. AIMS To determine the prevalence and risk factors for FSD. SETTINGS AND DESIGN A cross-sectional survey in a medical outpatient clinic of a tertiary care hospital. MATERIALS AND METHODS We administered a Tamil version of the Female Sexual Function Index (FSFI) to 149 married women. We evaluated putative risk factors for FSD. We elicited participants attributions for their sexual difficulties. STATISTICAL ANALYSIS We estimated the prevalence of possible FSD and sexual difficulties from published FSFI total and domain cut-off scores. We used logistic regression to identify risk factors for possible FSD. RESULTS FSFI total scores suggested FSD in two-thirds of the 149 women (73.2%; 95% confidence intervals [CI] 65.5% to 79.6%). FSFI domain scores suggested difficulties with desire in 77.2%; arousal in 91.3%; lubrication in 96.6%; orgasm in 86.6%, satisfaction in 81.2%, and pain in 64.4%. Age above 40 years (odds ratios [OR] 11.7; 95% CI 3.4 to 40.1) and fewer years of education (OR 1.2; 95% CI 1.0 to 1.3) were identified by logistic regression as contributory. Women attributed FSD to physical illness in participant or partner, relationship problems, and cultural taboos but none had sought professional help. CONCLUSIONS Sexual problems suggestive of dysfunction, as suggested by FSFI total and domain scores, are highly prevalent in the clinic setting, particularly among women above 40 and those less educated, but confirmation using locally validated cut-off scores of the FSFI is needed.

Contrast induced nephropathy in urology.

Intravenous contrast agents have a distinct role in urological imaging: to study precise anatomical delineation, vascularity, and to assess the function of the renal unit. Contrast induced nephropathy (CIN) is a known adverse effect of intravenous contrast administration. The literature on incidence, pathophysiology, clinical features, and current preventive strategies available for CIN relevant to urologists was reviewed. A search of the PubMed database was done using the keywords nephropathy and media, prevention and control or prevention Contrast media (explode), all adverse effects, and kidney diseases (explode). An online search of the EMBASE database for the time ranging from 1977 to February 2009 was performed using the keywords ionic contrast medium, adverse drug reaction, major or controlled clinical study, human, nephrotoxicity, and kidney disease. Current publications and data most relevant to urologists were examined. CIN was the third most common cause of hospital-acquired renal failure. The incidence is less common with intravenous contrast administration as compared with intra-arterial administration. The pathogenesis of contrast mediated nephropathy is due to a combination of toxic injury to renal tubules and medullary ischemic injury mediated by reactive oxygen species. CIN most commonly manifests as a nonoliguric and asymptomatic transient decline in renal function. Patients who developed CIN were found to have increased mortality, longer hospital stay, and complicated clinical course. An overview of risk factors and risk prediction score for prognostication of CIN are elaborated. Preventive strategies including choice of contrast agents, maximum tolerated dose, role of hydration, hydration regime, etc. are discussed. The role of N- acetyl cysteine, Theophylline, Fenoldapam, Endothelin receptor antagonists, iloprost, atrial natriuretic peptide, and newer therapies such as targeted renal therapy (TRT) are discussed. A working algorithm based on current evidence is proposed. No current treatment can reverse or ameliorate CIN once it occurs, but prophylaxis is possible.

Effect of hypospadias on sexual function and reproduction.

Hypospadias is a highly prevalent congenital anomaly. The impact of the defect and operative interventions on sexual and reproductive function has been addressed by few publications. It is essential to know the possible outcomes of intervention for appropriate counseling, operative planning, and follow-up. English articles indexed in Pubmed dealing with the long-term sexual and reproductive outcome following hypospadias repair from 1965 to 2007 were reviewed. To our knowledge, there was no prospective trial comparing the impact of various techniques on sexual outcome. There is considerable discordance in literature regarding the effects on sexual function. A few publications report patient and partner dissatisfaction with the appearance of genitalia. Sexual dissatisfaction is often attributed to penile size. Ejaculatory disturbances range between 6 and 37% of operated individuals. There is no convincing evidence for impaired fertility. The long-term follow-up is essential to identify problems and to address them appropriately. Literature documenting the outcome of specific operative procedures and analysis based on severity of hypospadias will be informative. The long-term follow-up of the newer techniques which are more commonly used are awaited.

Hidden penile fracture: An unusual presentation and review of literature

Penile fractures, a not so uncommon urological emergency, mostly present with a characteristic history and physical examination. Here, we present an atypical case where even in the absence of physical findings, a characteristic history led us to penile exploration and timely repair, highlighting the importance of careful history-taking in these cases.
