Efficacy, tolerability and safety of darifenacin, an M(3) selective receptor antagonist: an investigation of warning time in patients with OAB.

This double-blind, randomised placebo-controlled, multicentre study evaluated the efficacy, tolerability and safety of 12 weeks' treatment with controlled release darifenacin 15 mg once daily (qd), in 445 patients with overactive bladder (OAB). The primary endpoint was warning time (time from first sensation of urgency to voiding), and secondary endpoints included urge incontinence episodes and volume voided. Darifenacin treatment resulted in numerical increases in warning time, but these were not significant compared with placebo -- highlighting difficulties in assessing this parameter. Significant improvements were seen with darifenacin vs. placebo in urge incontinence episodes/week, volume voided and quality of life (QoL). Darifenacin was associated with increases in urgency-free time (UFT; time between any void to the next urgency event) vs. placebo. Treatment was well tolerated; the most commonly reported adverse events were the typical antimuscarinic effects of dry mouth and constipation, both infrequently leading to discontinuation. This study demonstrated the difficulty in measuring warning time, due in part to its subjective nature; the authors believe further investigation is warranted to allow urgency to be better defined. Further investigation of UFT is required to determine its role in evaluating urgency. The study confirmed that darifenacin 15 mg qd is an effective and well-tolerated treatment for OAB, which improves QoL.

The gonadotropin-releasing hormone antagonist abarelix depot versus luteinizing hormone releasing hormone agonists leuprolide or goserelin: initial results of endocrinological and biochemical efficacies in patients with prostate cancer.

PURPOSE: We contrasted the endocrinological and biochemical efficacies of abarelix depot, a pure gonadotropin-releasing hormone antagonist, with a prospective concurrent control cohort receiving luteinizing hormone releasing hormone (LH-RH) agonists with or without antiandrogen for treatment of patients with prostate cancer receiving initial hormonal therapy. MATERIALS AND METHODS: In this phase 2 open label study 242 patients with prostate cancer requiring initial hormonal treatment received abarelix depot (209) or LH-RH agonists (33) with or without antiandrogen. A total of 100 mg. abarelix depot was delivered intramuscularly every 28 days with an additional injection on day 15. LH-RH agonists with or without antiandrogen were administered according to the depot formulation used. Endocrine efficacy was measured by the absence of testosterone surge and rapidity of castration onset. The rate of prostate specific antigen decrease was assessed. RESULTS: No patient treated with abarelix depot had testosterone surge during week 1 compared with 82% of those treated with LH-RH agonists. The concomitant administration of antiandrogen had no effect. During the first week of drug administration, in 75% of patients treated with abarelix depot and in 0% of those treated with LH-RH agonist medical castration was achieved. Prostate specific antigen decrease was faster, with no flare or surge in patients treated with abarelix depot. Abarelix depot was well tolerated. CONCLUSIONS: Abarelix depot represents a new class of hormonal therapy, gonadotropin releasing hormone antagonists, that has rapid medical castration and avoids the testosterone surge characteristic of LH-RH agonists.

Serum prostate-specific antigen and prostate volume predict long-term changes in symptoms and flow rate: results of a four-year, randomized trial comparing finasteride versus placebo. PLESS Study Group.

OBJECTIVES: To determine whether baseline prostate-specific antigen (PSA), in addition to prostate volume, is associated with long-term changes in symptoms and urinary flow rate. METHODS: Three thousand forty men with benign prostatic hyperplasia enrolled in the PLESS trial were randomly assigned to finasteride 5 mg or placebo for 4 years. Symptoms and flow rate were assessed every 4 months, and data were analyzed by dividing the patients into three groups by baseline PSA tertiles (0 to 1.3, 1.4 to 3.2, and 3.3 ng/mL or greater) and baseline prostate volume tertiles (14 to 41, 42 to 57, and 58 to 1 50 mL). RESULTS: After the initial placebo effect, a slow deterioration in symptoms over time was observed in the placebo-treated men with a baseline PSA 1.4 ng/mL or greater. However, placebo-treated men in the lowest PSA tertile (less than 1.4 ng/mL) had sustained symptomatic improvement that was not seen in placebo-treated men in the higher tertiles (P<0.001). In all finasteride-treated groups, there was initial improvement followed by maintenance or continued symptom improvement over time (approximately 3 to 3.5 points by the end of 4 years). The differences in symptom score improvement between placebo and finasteride were marginal for men with baseline PSA levels less than 1.4 ng/mL (P = 0.128) but were highly significant for men with PSA levels 1.4 ng/mL or greater (P<0.001). Urinary flow rate results were similar to those observed for symptoms. Analysis of symptom and flow rate data by prostate volume tertiles in a 10% subset of men yielded similar results, namely a deterioration of symptoms and flow rate in the two higher tertiles treated with placebo (greater than 41 mL) and a sustained improvement in all three groups of finasteride-treated patients. CONCLUSIONS: Baseline PSA and prostate volume are good predictors of long-term symptomatic and flow rate changes. Baseline PSA levels of 1.4 ng/mL or greater and enlarged prostate glands predict the best long-term response to finasteride compared with placebo.

Group psychoeducation of relatives of schizophrenic patients: two-year experiences.

In order to assess the feasibility and acceptability of group psychosocial education for the relatives of schizophrenics in the community, a 2-year project was carried out in two cities: Jinan and Shanghai, China. The completed sample included 682 cases in the experimental group and 366 cases in the control group. The experimental group received group psychotherapy including 14 lectures and five group discussions with conventional services, and the control group had conventional services only. The annual relapse rate in the experimental group was much lower than that in the control group (17.6 and 23.2%, P < 0.01) and the rate of regular work in the experimental group was higher than that in the control group (37.5 and 30.0%, P < 0.05). At the end of the second year, the relatives in the experimental group had less care burden, better mental and physical health status and more knowledge of caring for schizophrenics than those in the control group. This approach was well accepted by both mental health workers and relatives of schizophrenics and the rate of drop-out was 18.4% only during the 2-year period.

Recent developments in the care, treatment, and rehabilitation of the chronic mentally ill in Greece.

The chronic mentally ill in Greece are primarily cared for in large public mental hospitals or by their families because of the absence of community-based alternatives and the centralization of existing services in Athens and Thessaloniki. However, in the last decade new legislation to improve the lives of the chronically ill has been passed, additional day care facilities have been opened, and the development of decentralized mental health services has been scheduled by the National Health System. A case report illustrates the care provided at Greece's first community mental health center, established in 1979 in Athens.
