ABSTRACT
The aim of this study was to evaluate the impact of risk factors of erectile dysfunction (ED) after transurethral resection of the prostate (TURP) in men with lower urinary tract symptoms caused by bladder outlet obstruction secondary to benign prostatic hyperplasia. The study was conducted prospectively on 178 consecutive patients (normal IIEF-5 before surgery, ≥ 22) who underwent TURP. Patients were assessed before surgery and at 12 months. At 12 months, the IIEF-5 score significantly decreased from24 to 18 (p<0.0001). No statistical associations were found between hypertension, diabetes, dyslipidemia and capsular perforation and the development of ED after TURP. Operating time, duration of catheterization, and BMI did not determine a significant decrease of the IIEF-5 score after TURP. On univariable and multivariable linear regression analysis, age was the only risk factor associated with newly-reported ED 12 months after TURP (p<0.0001). On univariable andmultivariable logistic regression analysis, patients older than 65 yr had an higher risk of developing ED after TURP (p<0.0001) and they developed a lower IIEF-5 score (p<0.0001) at followup when compared with those ≤ 65 yr. These results suggest that age of patients represents an independent risk factor of ED at 12 months follow-up after TURP.

The study of G6Pase and GK activities in human liver (needle biopsies) in overnight fasted obese NIDDM patients has shown that, while G6Pase was unchanged, GK was higher (+ 55%, P less than 0.05) than in control subjects. Consequently, the G6Pase/GK ratio (which roughly reflects hepatic glucose production) was significantly reduced (-36%) in the obese diabetic group, due to more GK activity (glucose uptake). This contrasts with the activity in IDDM and nonobese NIDDM patients (where the G6Pase/GK ratio is elevated and normal, respectively) and would suggest that in the obese diabetic subjects, hepatic glucose production is not a major factor contributing to the maintenance of hyperglycemia in the overnight fasting state (leaving peripheral insulin resistance as the major cause of hyperglycemia).

Two patients had the initial complaint of fluctuating paraparesis, which was most evident at menstruation. One patient had a semimonthly fluctuating deficit. Spinal cord compression and ischemia, secondary to the vascular mass, were considered the most likely mechanisms. Blood levels of estrogen and progesterone during the menstrual cycle may have had a contributory effect. Fluctuating spinal cord deficits associated with a consistent portion of the menstrual cycle should alert the physician to the possibility of an arteriovenous malformation of the spinal cord.
