Four patients developed penile erection when regional anaesthesia was induced with spinal block. In another patient, penile erection developed during fentanyl-induced general anaesthesia. Injection of metaraminol into corpus cavernosum successfully achieved detumescence in all these patients. The dose of metaraminol ranged from 10 to 25 micrograms, much less than that required for the treatment...

How Common Is It? Kinsey et al reported the results of a survey conducted on 15,781 men. The survey suggested that the prevalence of ED was less than 1% in men under age 30, 6.7% in men between the ages of 45 to 55, and 25% in men above 65 years.3 The Massachusetts Male Aging Study (MMAS) was a cross-sectional community-based randomsample survey in men aged 40 to 70. The study was conducted bet...

(b) All masonry walls over eight feet in height shall be adequately braced to preve...

In the penis, nitric oxide (NO) can be formed by both neuronal NO synthase and endothelial NOS (eNOS). eNOS is activated by viscous drag/shear stress in blood vessels to produce NO continuously, a process mediated by the phosphatidylinositol 3-kinase (PI3kinase)/Akt pathway. Here we show that PI3-kinase/Akt physiologically mediates erection. Both electrical stimulation of the cavernous nerve an...
