Actinobaculum was isolated from urine only after prolonged incubation in 5% CO(2) after discrepancy between urine Gram stain and initial culture results was observed. Additional patients were diagnosed using this method. The prevalence of Actinobaculum species in urinary tract infections is underestimated since it is not isolated by routine urine culture procedures.
OBJECTIVE: To assess the long-term safety and tolerability of tadalafil for patients with erectile dysfunction (ED). PATIENTS AND METHODS: This was a multicentre, open-label, 24-month extension trial involving 1173 men with ED. The mean age was 57 (range 23-83) years and 74.8% of patients were taking concomitant medications for comorbid conditions, including diabetes mellitus in 30.5% of men and hypertension in 29.5%. These patients had participated in 1 of 5 previous 8-week or 12-week randomised, double-blind, placebo-controlled tadalafil studies. In the present trial, the starting 10mg dose of tadalafil could be increased to 20mg if the patient could not achieve satisfactory intercourse or reduced to 5mg for an adverse event that was persistent, intolerable and judged by the investigator to be related to tadalafil. RESULTS: Four hundred ninety-three (42.0%) men completed 24 months of treatment. In addition, a further 234 (19.9%) completed 18 months of treatment due to a sponsor decision to reduce the study duration. The total tadalafil exposure was 1676.0 patient-years. Tadalafil was safe and well tolerated. Headache (15.8%), dyspepsia (11.8%), nasopharyngitis (11.4%), and back pain (8.2%) were the most common treatment-emergent adverse events. The rate of discontinuations due to adverse events for this 18-24-month study was 6.3% and the rate for any individual event was <1%. Serious adverse events occurred in 8.6% of patients. No consistent pattern of serious adverse events assessed as causally associated with tadalafil administration was observed. None of the four deaths that occurred during the study was assessed as tadalafil related. There were no clinically significant laboratory or electrocardiographic findings or changes in vital signs in mean baseline-to-endpoint analysis attributable to tadalafil. Tadalafil administration was not causally associated with drug-induced hepatotoxicity, neutropenia, thrombocytopenia, or renal dysfunction. CONCLUSION: Tadalafil at doses of 5, 10, or 20mg taken as needed up to once daily for 18 to 24 months was safe and well tolerated. These findings support the long-term use of tadalafil in the clinical management of erectile dysfunction.
OBJECTIVE: To assess the efficacy and safety of sildenafil citrate (Viagra, Pfizer Inc., USA) in a double-blind, placebo-controlled, dose-escalation study over a period of 26 weeks in men with erectile dysfunction of a broad spectrum of aetiology. PATIENTS AND METHODS: In all, 315 patients from five countries were randomized to receive treatment with placebo (156 men) or sildenafil (159 men). Significant concomitant medical conditions were hypertension (20%), a history of pelvic surgery (19%), diabetes mellitus (15%), and ischaemic heart disease (10%). Patients randomized to treatment received a starting dose of 25 mg of sildenafil or matching placebo, which could be increased to 50 mg and then to 100 mg of sildenafil, based on efficacy and tolerability. Assessments of efficacy comprised the 15-item International Index of Erectile Function (IIEF), including question three (ability to achieve an erection) and question four (ability to maintain an erection), a partner questionnaire, an overall efficacy question, and event-log data. RESULTS: After 12 weeks of treatment, 26%, 32% and 42% of patients were taking 25, 50 and 100 mg of sildenafil, respectively. A similar distribution of doses was reported after 26 weeks of treatment. Treatment with sildenafil significantly improved the patients' abilities to achieve and maintain an erection compared with treatment with placebo (P < 0.001). Scores for four of the five sexual function domains of the IIEF (erectile function, orgasmic function, intercourse satisfaction and overall satisfaction) also improved significantly (P < 0.001). There was a significant improvement in the mean score for the erectile function domain, regardless of the aetiology of erectile dysfunction (P < 0.001). After 12 weeks and 26 weeks of treatment, 82% and 79% of patients receiving sildenafil reported improved erections, compared with 24% and 23% of patients receiving placebo, respectively (P < 0.001). Treatment-related adverse events were mild to moderate and occurred in 27% of patients receiving sildenafil, compared with 8% of patients receiving placebo. CONCLUSION: Sildenafil is an effective and well-tolerated treatment for men with erectile dysfunction of a broad spectrum of aetiology.
Many women will spend one third of their lifetime after menopause. A growing number of options are available for the treatment of menopausal symptoms like vasomotor instability and vaginal atrophy, as well as the long-term health risks such as cardiovascular disease and osteoporosis that are associated with menopause. Currently, hormone replacement therapy (estrogen with or without progestin) is the primary treatment for the symptoms and long-term risks associated with menopause. However, recent evidence calls into question the protective effect of estrogen on cardiovascular disease risk. The association of risk for breast cancer with estrogen replacement therapy also has not been fully clarified. In addition, many women cannot or choose not to take hormones. For treatment of osteoporosis and heart disease, pharmacologic choices include antiresorptive agents such as bisphosphonates and calcitonin, and estrogens or selective estrogen receptor modulators such as raloxifene. In addition, complementary options that include vitamins, herbal treatments, exercise and other lifestyle adaptations are gaining increased interest. The growing number of choices and questions in this area emphasizes the need to individualize a treatment plan for each woman to meet her specific needs.

Long-term efficacy and safety of Alprostadil-Alfadex (EDEX/VIRIDAL) in intracavernous self-injection therapy for chronical erectile failure was investigated in a four year running multicenter European trial. Of the 16,886 protocolled injections 93% (15,713) resulted in rigid erections followed by successful sexual intercourse. Reported side effects by patients were prolonged erections > 6 h only occurring during the first year in 1.2% (2 out of 162), painful erections in 29% (47 out of 162) during the first year and decreasing to 12.1% by year 4, hematomas, neither requiring therapeutic measures nor impeding sexual performance in 33.3% (54 out of 162) in year 1 with a decrease to 12.1% by year 4, fibrotic penile alterations such as nodules, plaques or deviations in 11.7% (19 out of 162) with spontaneous healing in 48% (9 out of 19). Of the 162 patients involved in this trial 54 completed the 4 y. Of the 54 completers 91.4% considered the tolerability good or very good and were satisfied or very satisfied with self-injection therapy with Alprostadil-Alfadex. The respective rates of the female partners were 51.7% very satisfied and 39.7% satisfied. These data of the world-wide longest running prospective trial with a vasoactive drug in self-injection therapy provided impressive proof that Alprostadil-Alfadex represents a very effective and safe treatment for erectile dysfunction of both psychogenic and organogenic origin.
