OBJECTIVES: To investigate the tolerability of tolterodine extended release (ER) in older subjects with overactive bladder (OAB). METHODS: This was a retrospective analysis of pooled data from five large, randomised, double-blind, placebo-controlled trials. Subjects with OAB symptoms, including urinary frequency and urgency (and nocturia in two studies) with or without urgency urinary incontinence, received qd treatment with tolterodine ER (4 mg) or placebo for 8-12 weeks. Data were stratified post hoc by age group:< 65 (n = 2531), 65-74 (n = 1059) and > or = 75 years (n = 573). Tolerability was assessed by evaluating the occurrence of adverse events (AEs). AE occurrences from each study were mapped to the MedDRA coding dictionary of preferred terms. RESULTS: Discontinuation rates were slightly higher among subjects > or = 75 years of age vs. those < 65 years of age; however, this was observed in subjects treated with placebo as well as tolterodine ER. Overall, there were no significant differences in the occurrence of dry mouth, headache, constipation, nausea, urinary tract infection, blurred vision, dry eye, dizziness and micturition disorder in older (65-74 or > or = 75 years) vs. younger (< 65 years) subjects treated with tolterodine ER relative to placebo (treatment x age; all p > 0.1). Dry mouth was the only AE consistently associated with tolterodine ER treatment (< 65 years, 17%; 65-74 years, 16%;> or = 75 years, 15%). The occurrence of all other AEs was < or = 5% in most age and treatment cohorts. Most AEs were mild or moderate in all age and treatment cohorts. CONCLUSION: The nature and frequency of AEs associated with tolterodine ER treatment were similar across age groups in subjects with OAB, suggesting that tolterodine ER was not associated with an increased risk of AEs in older vs. younger subjects and, thus, is a suitable first-line pharmacotherapy treatment for OAB in this population.

To study sexual activity, the prevalence of sexual dysfunction and related help-seeking behaviors among mature adults in the United States of America, a telephone survey was conducted in 2001-2002. A total of 1491 individuals (742 men/749 women) aged 40-80 years completed the survey. Overall, 79.4% of men and 69.3% of women had engaged in sexual intercourse during the 12 months preceding the interview. Early ejaculation (26.2%) and erectile difficulties (22.5%) were the most common male sexual problems. A lack of sexual interest (33.2%) and lubrication difficulties (21.5%) were the most common female sexual problems. Less than 25% of men and women with a sexual problem had sought help for their sexual problem(s) from a health professional. Many men and women in the United States report continued sexual interest and activity into middle age and beyond. Although a number of sexual problems are highly prevalent, few people seek medical help.International Journal of Impotence Research advance online publication, 26 February 2009; doi:10.1038/ijir.2009.7.

Background: The Global Study of Sexual Attitudes and Behaviours was a survey of 27 500 men and women in 29 countries. Here we report the sexual activity, the prevalence of sexual difficulties and related help-seeking behaviour among participants in Australia. Methods: A telephone survey was conducted in Australia in 2001-2002, with interviews based on a standardised questionnaire. A total of 1500 individuals (750 men and 750 women) aged 40 to 80 years completed the survey. The questionnaire covered demographic information, overall health, and sexual behaviours, attitudes and beliefs. Results: Overall, 83% of men and 74% of women had engaged in sexual intercourse during the 12 months preceding the interview, and 38% of all men and 29% of all women engaged in sexual intercourse more than once a week. Early ejaculation (23%), erectile difficulties (21%) and a lack of sexual interest (18%) were the most common male sexual difficulties. The most frequently reported female sexual difficulties were: lack of sexual interest (33%), lubrication difficulties (26%) and an inability to reach orgasm (25%). Older age was a significant predictor of male erectile difficulties and of lubrication difficulties in women. Only a minority of men and women had sought help for their sexual difficulty(ies) from a health professional. Conclusions: Many middle-aged and older adults in Australia report continued sexual interest and sexual activity. Several sexual difficulties are highly prevalent in this population, but those experiencing these difficulties rarely seek medical help. This may be because they do not perceive such difficulties as serious or sufficiently upsetting.

PURPOSE: The relationship between lower urinary tract symptoms and depressive symptoms was assessed using data from the Male Attitudes Regarding Sexual Health study. MATERIALS AND METHODS: Lower urinary tract symptoms, depressive symptoms and erectile dysfunction were assessed using International Prostate Symptom Score, Center for Epidemiologic Studies Depression Scale and a validated question from the Massachusetts Male Aging Study. Sociodemographic, clinical and other data were also collected. Odds ratios and 95% CIs were determined using weighted multivariate logistic regression stratified by race/ethnicity and age. RESULTS: Of 3,291 randomly selected men 2,173 completed the interview. Overall odds of lower urinary tract symptoms were increased in men who reported depressive symptoms (OR 2.68, 95% CI 1.60-4.47, p <0.01), erectile dysfunction (OR 1.73, 95% CI 1.11-2.71, p <0.05) and unhappiness/dissatisfaction on the International Prostate Symptom Score quality of life item (OR 10.72, 95% CI 5.56-20.69, p <0.01), and those 60 to 69 years old (OR 1.99, 95% CI 1.14-3.46, p <0.05) and 70 years or older (OR 1.91, 95% CI 1.06-3.43, p <0.05). Increased odds of lower urinary tract symptoms were associated with depressive symptoms for white (OR 2.60, 95% CI 1.39-4.85, p <0.01) and Hispanic men (OR 4.14, 95% CI 1.15-14.95, p <0.05). Odds of depressive symptoms were increased in men reporting lower urinary tract symptoms (OR 2.64, 95% CI 1.57-4.43, p <0.001), especially Hispanic men 50 to 59 years old (OR 133.17, 95% CI 18.40-963.87, p <0.01) and black men older than 60 years (OR 21.61, 95% CI 3.04-153.55, p <0.01), as well as men 40 to 49 years old expressing unhappiness/dissatisfaction on the International Prostate Symptom Score quality of life item (OR 6.80, 95% CI 1.77-26.16, p <0.01), and Hispanic (OR 10.76, 95% CI 3.88-29.80, p <0.01) and black men reporting erectile dysfunction (OR 4.77, 95% CI 1.15-19.78, p <0.05), but not white men reporting erectile dysfunction (OR 1.05, 95% CI 0.48-2.28, p <0.91). CONCLUSIONS: Lower urinary tract symptoms and depressive symptoms are strongly associated, and exhibit reciprocal relationships. Erectile dysfunction increases the odds of both disorders.

AIMS: Relationships were evaluated between treatment-related improvements in overactive bladder (OAB) symptoms as recorded in bladder diaries and patient-reported symptom bother, bladder-related problems and health-related quality of life (HRQL). METHODS: A post hoc analysis was performed on data from patients with OAB (n = 863) enrolled in a 12-week open-label trial of tolterodine extended release (ER) in a primary care setting. At baseline and week 12, patients recorded every micturition, urgency episode and urgency urinary incontinence episode in 3-day bladder diaries. Patients also completed the Overactive Bladder Questionnaire (OAB-q) and Patient Perception of Bladder Condition (PPBC). Relationships between week 12 changes in bladder diary variables and OAB-q and PPBC scores were evaluated using Spearman correlations. RESULTS: By week 12, tolterodine ER-related improvements in all bladder diary variables were significantly correlated with improvements on the PPBC (r = 0.26-0.36; p < 0.001), OAB-q Symptom Bother scale (r = 0.30-0.51; p < 0.001), and all OAB-q HRQL domains (r =-0.24 to -0.42; p < 0.001), although the correlations were generally small to moderate in size. Improvements on the PPBC were also significantly correlated with improvements on the OAB-q Symptom Bother scale (r = 0.63; p < 0.001) and all HRQL domains (r =-0.40 to -0.59; p < 0.001). CONCLUSIONS: Tolterodine ER-related improvements in OAB symptoms (assessed by diary variables) and patients' perceptions of the changes in symptom bother, bladder-related problems and HRQL (assessed by PPBC and OAB-q) were significantly correlated. The OAB-q and the PPBC provide a relevant and important patient perspective for OAB treatment evaluation.

PURPOSE: Several studies have shown that men with lower urinary tract symptoms are more likely to experience erectile dysfunction. All except 1 of these studies were cross-sectional, limiting inferences about whether lower urinary tract symptoms precipitate erectile dysfunction. MATERIALS AND METHODS: The association between lower urinary tract symptoms and incident erectile dysfunction was examined prospectively in the Health Professionals Follow-Up Study. Lower urinary tract symptoms were assessed biennially by the American Urological Association symptom index, which captures symptoms of frequency, urgency and force of urinary stream. Severe lower urinary tract symptoms was defined as a symptom score of 20 points or greater and no lower urinary tract symptoms was defined as a score of 7 points or less in men not treated for lower urinary tract symptoms. In 2000 the men were asked to rate erectile function for several periods. Erectile dysfunction was defined as poor or very poor function, or erectile dysfunction medication use, while no erectile dysfunction was defined as very good or good function and no erectile dysfunction medication use. We estimated the RR using Poisson regression, adjusting for age and other potentially confounding factors. RESULTS: We observed 3,953 incident erectile dysfunction cases among 17,086 men. Men with severe lower urinary tract symptoms in 1994 or earlier had a statistically significant 40% higher risk of erectile dysfunction subsequently than men without lower urinary tract symptoms. The risk of erectile dysfunction increased with increasing lower urinary tract symptom severity (p trend <0.0001). The positive association between lower urinary tract symptoms and erectile dysfunction was stronger in younger than in older men (p interaction = 0.03). CONCLUSIONS: This study provides evidence that men with lower urinary tract symptoms are more likely to have erectile dysfunction subsequently.

OBJECTIVES To study sexual activity, the prevalence of sexual dysfunction, and related help-seeking behaviour patterns among middle-aged and older people in the UK and Europe. SUBJECTS AND METHODS A telephone survey was conducted using a structured questionnaire covering demographics, health, relationships, and sexual behaviour, attitudes and beliefs. In the UK, 1500 individuals completed the survey. RESULTS Overall, 69% of men and 56% of women reported having sexual intercourse during the past year. The most common male sexual problems, i.e. early ejaculation (20%) and erectile dysfunction (18%), were more common in the UK than in other European regions. The most common female sexual problems, i.e. a lack of sexual interest (34%) and a lack of pleasure in sex (25%), were also more common in the UK than in other European regions. Only 26% of men and 17% of women had discussed their sexual problem(s) with a doctor. CONCLUSION Many people in the UK maintain sexual interest and activity into middle age and beyond. Although they experience sexual problems, few seek medical help. This might be because they do not perceive such problems as serious or sufficiently upsetting, and/or are not aware of available treatments.

Aim: To assess the incidence of serious cardiovascular disease (CVD) events [i.e. myocardial infarction (MI) and stroke] and all-cause mortality in men with erectile dysfunction (ED) who received prescriptions for sildenafil. Methods: The International Men's Health Study (IMHS) was a prospective, observational cohort study of patients with ED and a new or existing prescription for sildenafil. Baseline and follow-up questionnaires provided information on demographics, CVD risk factors and ED. Postevent questionnaires were mailed to patients following possible nonfatal CVD events to collect information related to exposure to sildenafil/ED treatments before the event. Results: Thirty-five CVD events were reported in 30 patients in the analysis set (n = 3813). The incidence of all-cause mortality, MI and stroke was 0.4, 0.6 and 0.1 per 100 patient-years of observation respectively. Among the six men who reported using sildenafil in the month before a nonfatal CVD event, two reported use in the 24 h before the event. Conclusion: The results of the IMHS support previous reports that ED and CVD are often comorbid and share risk factors.

Erectile dysfunction is common among individuals with Parkinson's disease, but it is unknown whether it precedes the onset of the classic features of Parkinson's disease. To address this question, the authors examined whether erectile dysfunction was associated with Parkinson's disease risk in the Health Professionals Follow-up Study. Analyses included 32,616 men free of Parkinson's disease at baseline in 1986 who in 2000 completed a retrospective questionnaire with questions on erectile dysfunction in different time periods. Relative risks were computed using Cox proportional hazards models adjusting for age, smoking, caffeine intake, history of diabetes, and other covariates. Among men who reported their erectile function before 1986, 200 were diagnosed with Parkinson's disease during 1986-2002. Men with erectile dysfunction before 1986 were 3.8 times more likely to develop Parkinson's disease during the follow-up than were those with very good erectile function (relative risk = 3.8, 95% confidence interval: 2.4, 6.0; p < 0.0001). Multivariate-adjusted relative risks of Parkinson's disease were 2.7, 3.7, and 4.0 (95% confidence interval: 1.4, 11.1; p = 0.008) for participants with first onset of erectile dysfunction (before 1986) at 60 or more, 50-59, and less than 50 years of age, respectively, relative to those without erectile dysfunction. In conclusion, in this retrospective analysis in a large cohort of men, the authors observed that erectile dysfunction was associated with a higher risk of developing Parkinson's disease.

Aims: Lower urinary tract symptoms (LUTS) are categorised as storage (urgency, frequency, nocturia and incontinence), voiding (sensation of incomplete emptying, hesitancy, weak stream and straining) or mixed symptoms. Methods: In this US population-based study, we investigated the prevalence of male LUTS and the relative frequency of the LUTS subtypes, and we evaluated associations between LUTS and age, race/ethnicity and erectile dysfunction (ED). The Male Attitudes Regarding Sexual Health study included a nationally representative sample of non-Hispanic black, non-Hispanic white and Hispanic men aged >/= 40 years. Participants completed a questionnaire including items on ED and the International Prostate Symptom Score (IPSS). The prevalence and subtypes of LUTS were investigated post hoc by age, race/ethnicity and the presence of ED. Results: The overall prevalence rates of storage (13%) and mixed (9%) symptoms were higher than that of voiding symptoms (6%). The prevalence of storage symptoms was similar across age groups, whereas voiding and mixed symptoms increased with age. Among men with IPSS >/= 8, the rates of storage (29%) and mixed (38%) symptoms were also higher than voiding symptoms (23%). Distributions of the LUTS subtypes were comparable among black, white and Hispanic respondents with IPSS >/= 8. The overall prevalence rate of ED (40%) increased with age among those with IPSS >/= 8. Isolated storage symptoms were more than twice as common as isolated voiding symptoms among US men >/= 40 years of age. Conclusion: Careful attention to individual symptoms may help distinguish storage LUTS from voiding LUTS, a distinction that has important implications for treatment.
