Risk factors in wound infection following urologic operations: a prospective study.

A total of 134 urologic operations were studied prospectively for postoperative wound infection, the methodology involving direct intraoperative swab taking. Patients' variables were (mean +/- SD): age 32.4 +/- 20.7 years, Quetelet index 27.4 +/- 8, duration of operation 98 +/- 34 minutes, and male:female ratio 9.3:1. Of the 131 intraoperative swabs 28 (21%) were positive, 97% of the organisms being aerobic; 16% of the patients were nasal carriers of S. aureus. The overall wound infection rate was 9%, and it prolonged hospital stay by six days average. Significant risk factors (and their magnitude) were: age over 60 years (x 2.2), prolonged preoperative hospital stay (x 15), and wound contamination (x 4.3 and x 14.3 for classes 3 and 4 wounds respectively). Neither diabetes mellitus, obesity, nor surgeon's rank was contributory. We conclude that, although the 9% rate of postoperative wound infection was acceptable, appropriate prophylactic antibiotics may reduce it further, and, from our data, we would recommend an aminoglycoside (e.g. Amikacin) and Ampicillin combined.

Physicians' knowledge, attitude and practice towards erectile dysfunction in Saudi Arabia.

We aimed to test the knowledge, attitude and practice (KAP) of physicians towards erectile dysfunction in the Eastern province of Saudi Arabia. At a scientific meeting about erectile dysfunction, 159 physicians from both government and private sectors answered a 34-item questionnaire in private. The mean total KAP score for the group was below the expected standard of 60%. Male physicians scored significantly higher than females. Urologists scored the highest, followed by andrologists. Surprisingly, physicians with higher qualifications scored lower than those with intermediate qualifications and even less than general practitioners. Those who had practised for > or = 10 years scored better than those with < 10 years practice. The role of cardiologists in the diagnosis and management of erectile dysfunction is discussed.

Management of an unusually high postpubertal presentation of cryptorchidism.

A high proportion (43%) of postpubertal presentation of cryptorchid testes was found in 114 patients with undescended testes (UDT). Bilateral presentation of UDT was observed in 25% of patients. Orchiopexy was performed on 75% of postpubertal cases, the determinant factor for choice of operation being cosmetic and psychological. Follow-up results appear to be promising in this environment with very low incidence of testicular cancer.

Fracture of the penis: surgical management.

Fracture of the penis is a rare injury, only 135 patients having been reported by 1985. Our recent experience with six patients who underwent emergency surgery, has been documented. The results of treatment were excellent with complete recovery of function. The study recommends operative management as the treatment of choice.

Effect of ambrein, a major constituent of ambergris, on masculine sexual behavior in rats.

The effect of ambrein, a major constituent of ambergris, was studied on the sexual behavior of male rats. The rats were administered ambrein in doses of 100 and 300 mg/kg body weight. Male sexual activities were assessed by recording the erectile responses (penile erection) and homosexual mountings in the absence of female. The copulatory studies were carried out by caging males with receptive females brought into estrus with subcutaneous injections of estradiol benzoate and progesterone. The copulatory pattern of treated male rats (mountings, intromissions, ejaculations and refractory period), the pendiculations (yawns/stretches) and orientation activities towards females, the environment and themselves, were recorded. Ambrein produced recurrent episodes of penile erection, a dose-dependent, vigorous and repetitive increase in intromissions and an increased anogenital investigatory behavior, identifying the drug used in the present study as a sexual stimulant. It is conceivable from the present results that the ambrein-modified masculine sexual behavior in male rats supports the folk use of this drug as an aphrodisiac.
