In order to assess the prevalence of erectile dysfunction (ED), and its association with chronic diseases and impact upon sexual activity and satisfaction during sexual intercourse, a reproductive survey was conducted among 1002 Taiwanese men aged over 40 y. The information collected comprised age, gender, level of education, history of chronic diseases, and self-reported data pertaining to erectile function, sexual activity, and sexual satisfaction during sexual intercourse. The prevalence of ED amongst study subjects was 17.7%, and the frequency increased with age. A history of chronic diseases were significantly associated with ED (Po0.05). A reduced incidence of sexual activity and a decreased level of satisfaction during sexual intercourse were observed among subjects suffering from ED as compared to those not suffering such a condition. In conclusion, based upon the results of a community-based survey the prevalence of ED among Taiwanese men aged 40 y or more was 17.7% and it increased with age. It was also found that ED was associated with various chronic diseases and that it exerted a negative impact upon sexual activity and the level of satisfaction associated with its conduct.
Anterior cervical plate is a convenient and popular implant employed after corpectomy and bone grafting for traumatic or degenerative cervical spine disease. Although short-segment anterior cervical surgery may adequately be managed with anterior plate fixation alone, multilevel anterior cervical constructs exhibit a relatively high complication rate warranting a simultaneous posterior fusion. We report two patients undergoing two-level anterior corpectomy/fusion with a fixed anterior plate alone and exhibiting plate fracture in conjunction with pseudoarthrosis. The instrument failure was mainly attributed to pseudoarthrosis. However, improper contouring of the plate causing microstructural damage might create a weak point and contributed to this unusual hardware failure.
We present our experience with colour duplex sonography (Acuson 128) in the assessment of 83 impotent men. Cavernosal artery measurements were taken before and after the intracorporeal injection of papaverine. The peak velocities following papaverine injection correlated well with the degree of clinical response. Percentage diameter change corresponded with some groups of clinical erection grade, although it was not as good a discriminator as peak velocity. Twelve patients with 24 cavernosal arteries were also examined using pharmacological selective arteriography. Correlation between duplex sonography and arteriography showed an accuracy of 87.5%, specificity of 100.0% and sensitivity of 82.4%. All patients with a clinically good response following papaverine injection had peak bilateral cavernosal artery velocities greater than or equal to 25 cm/s. Amongst the remaining suboptimal responders, 18 also had this finding. Fifteen of these underwent pharmacological cavernosography and 14 exhibited venous leakage. Duplex sonography is a valuable and non-invasive tool in the assessment of impotence and can provide valuable information in deciding the course of further evaluation and treatment. The procedure was always completed more quickly with the guidance of colour Doppler.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
