Validation of the self-administered Danish Prostatic Symptom Score (DAN-PSS-1) system for use in benign prostatic hyperplasia.

OBJECTIVE: To validate the Danish Prostatic Symptom Score (DAN-PSS-1), a self-administered quality-of-life questionnaire comprising 12 questions related to voiding problems and the perceived bother of each individual symptom. METHODS: Using published results from several comparisons of other symptom scoring systems with DAN-PSS-1, the test-retest reliability, internal consistency, construct and content validity, and responsiveness of the DAN-PSS-1 system were assessed. RESULTS: The system was internally consistent (Cronbach's alpha = 0.73), the median test-retest reliability of answers to each question was 83.5% (range 0-99.7%) and the questionnaire was well understood by the patients. The DAN-PSS-1 system demonstrated a high degree of construct validity, correlating with the extensively used Madsen-Iversen score system (Spearman's correlation coefficient, rs = 0.51) and with the patients' answers to questions about how bothersome their symptoms were (rs = 0.71). The DAN-PSS-1 system discriminated clearly between patients with benign prostatic hyperplasia (BPH) and control subjects (an area under the receiver operating characteristic curve of 0.94). Finally, the DAN-PSS-1 was sensitive to changes following intervention, with scores decreasing from a median of 20 to zero 4 months after patients underwent transurethral prostatectomy and from a median of 11.5 to 7.5 (65%) after patients had received 4 months treatment with an alpha-blocker. CONCLUSIONS: The DAN-PSS-1 system is reliable, valid and responsive, and therefore can be recommended for assessing the severity of symptoms among patients presenting with lower urinary tract complaints suggestive of BPH and in the follow-up after intervention.

Clinical pharmacology of the lower urinary tract. New aspects.

Neurohistochemical, electron-microscopic, pharmacological and urodynamic investigations have over the past 10 years led to a new concept of the innervation and function of the lower urinary tract. A survey is given of the peripheral innervation, transmitters and receptor functions in the parasympathetic, sympathetic, somatic and sensory innervation of the lower urinary tract. Based on this, rational principles of pharmacological treatment are outlined in the management of the most common dysfunctions of detrusor function and the urethral closure mechanism. Furthermore, a survey is given of dysfunctions of the lower urinary tract which may arise inadvertently during pharmacotherapy of disorders of other organ systems.

Peroperative penicillins, bacteremia, and pelvic inflammatory disease in association with induced first-trimester abortion.

In a clinical, controlled trial including 474 women, 250 were randomised to prophylactic treatment with penicillin/pivampicillin and 224 to placebo treatment. Cervical, uterine, and blood cultures were obtained at abortion. In the treatment group, 13 percent developed bacteremia versus 14 percent in the placebo group. The distribution of species cultured from the cervix and uterus was not significantly different from that of the species recovered in the blood. A previous report found that women with a history of pelvic inflammatory disease (PID) carried a higher risk of contracting postabortal genital infection. However, the frequency of bacteremia in these women was not significantly different from the frequency in women without previous PID (p greater than 0.3). In women with and without postabortal infection, no significant differences were observed between the frequencies of bacteremia, either in the antibiotic group (p greater than 0.9) or in the placebo group (p greater than 0.7), suggesting that the release of bacteria into the blood stream from the instrumented tissues is without pathogenetic importance in postabortal infection.

Effect of cimetidine on upper gastrointestinal bleeding after renal transplantation: a prospective study.

In 97 consecutive patients undergoing renal transplantation the incidence of upper gastrointestinal bleeding was registered over 180 days after allocation to treatment with either cimetidine or placebo. Bleeding episodes occurred in 12 patients, 11 of whom were receiving placebo and only one cimetidine (p less than 0.01). All bleeding episodes occurred during the first month after allotransplantation. Treatment with cimetidine did not lead to an increased incidence of rejection of the allograft. It is concluded that cimetidine is effective and safe in protecting against upper gastrointestinal bleeding after renal transplantation.

Dysfunction of the bladder neck: a urodynamic study.

Urodynamic investigations were performed in 9 males, suffering from dysfunction of the bladder neck (detrusor bladder neck dyssynergia). The parameters of micturition were compared with the values in normal males and in patients with prostatic obstruction. By introducing a new factor, the maximum opening time, we found a characteristic pattern in dysfunction of the bladder neck, making selection of patients for endoscopic incision of the bladder neck possible. The maximum and mean flow rates increased significantly in 5 patients treated with incision of the bladder neck. The diagnostic value of voiding cystourethrography and urodynamic investigation is discussed.
