Erection quality scale: initial scale development and validation.

OBJECTIVES: The Erection Quality Scale (EQS) is a new, self-report measure for assessing the quality of penile erections. It is intended to complement existing diagnostic and outcome measures (eg, International Index of Erectile Function, Sexual Encounter Profile) in both clinical practice and outcomes research in erectile dysfunction (ED). METHODS: The initial phases of development and psychometric validation of the EQS are described. Specifically, qualitative research in patients and healthy men was used to generate relevant constructs. On the basis of the findings from these phases, and recommendations from an expert panel, seven constructs were selected for inclusion. Multiple items with different formats were drafted to measure each of the key constructs. An iterative process of cognitive testing, item revision, and item reduction was used to identify the 15 most appropriate items and their optimal response scales. This version of the scale was tested in a 200-subject discriminant validity study designed to gather data for a psychometric evaluation. Participants were classified into ED-untreated, ED-treated, and healthy control groups to evaluate the discriminant validity of the measure in men with different levels of erectile function. RESULTS: The study results supported a robust single-factor structure, indicating that the EQS provides an overall index of erection quality. An intraclass correlation coefficient of 0.85 denotes adequate test-retest reliability. Furthermore, the EQS correlated well with existing measures and differentiated patients from the three ED classifications, a preliminary indication of discriminant validity. CONCLUSIONS: The findings presented provide evidence of the scale's potential utility for measuring erection quality in future studies.

The effects of sleep loss and fatigue on resident-physicians: a multi-institutional, mixed-method study.

PURPOSE: To identify and model the effects of sleep loss and fatigue on resident-physicians' professional lives and personal well-being. METHOD: In 2001-02, 149 residents at five U.S. academic health centers and from six specialties (obstetrics-gynecology, emergency medicine, family medicine, internal medicine, pediatrics, surgery) were recruited for the study. Residents were all in good standing in their programs. In a mixed-methods design, focus groups consisted of an average of seven (range, three to 14) individuals in the same year of training and residency program, for a total of 60 interns and 89 senior residents. Trained moderators conducted focus groups using a standardized, semistructured discussion guide. Participants also completed a 30-item quantitative questionnaire assessing sleepiness and workplace sleep attitudes that included the Epworth Sleepiness Scale (ESS). RESULTS: Residents described multiple adverse effects of sleep loss and fatigue on learning and cognition; job performance, including professionalism and task performance; and personal life, including personal well-being and relationships with spouse or significant other and family. Only 16% of the sample scored within the "normal" range on the ESS; 84% scored in the range for which clinical intervention is indicated. Sleepiness was consistent across institution, specialty, years of training, age, gender, marital status, and having children. CONCLUSIONS: More residents perceived that sleep loss and fatigue had major impact on their personal lives during residency, leaving many personal and social activities and meaningful personal pleasures deferred or postponed. Sleep loss and fatigue also had major impact on residents' abilities to perform their work. This finding further substantiates the growing concern about the potential impact on professional development. These observations should be taken into account in developing new training guidelines and educational interventions for housestaff.

[Lower urinary tract symptoms and male sexual dysfunction: the multinational survey of the aging.male (MSAM-7)].

OBJECTIVES: Lower urinary tract symptoms (LUTS), which are often caused by benign prostatic hypertrophy (BPH), and sexual dysfunction are common in older men, with an overall prevalence of > 50% in men aged > 50 years. Men with LUTS have been reported to experience sexual dysfunction, including ejaculatory loss, painful ejaculation, and erectile dysfunction. This study was conducted to investigate the relationship between LUTS and sexual problems in aging men. METHODS: A large-scale, multinational survey was conducted in the US and six European countries to systematically investigate the relationship between LUTS and sexual dysfunction in older men. Detailed questionnaires were mailed to a national representative sample of men aged 50 to 80 years in each country. Selection was made on the basis of age, occupation, geographie region, and population density. LUTS and sexual function were assessed by validated symptom scales, including the International Prostate Symptom Score, the Danish Prostatic Symptom Score, and the International Index of Erectile Function. Subjects also completed a health and demographics questionnaire. RESULTS: A total of 34,800 surveys were mailed out, 14,254 were completed and returned, and 12,815 were deemed evaluable and included in the analysis. Results were consistent from one country to another. Although 90% of the men had LUTS, only 19% had sought medical help for urinary problems and only 11% were medically treated. Sexual activity was reported by 83% of the sample, with 71% reporting at least one episode of sexual activity during the previous 4 weeks. Sexual disorders and their bothersomeness were strongly related to both age and severity of LUTS. The relationship between sexual problems and LUTS is independent of comorbidities such as diabetes, hypertension, cardiac disease, and hypercholesterolemeia. CONCLUSIONS: Sexual activity is common in a majority of men over age 50 and is an important component of overall quality of life. The presence and severity of LUTS are independent risk factors for sexual dysfunction in older men. These results highlight the clinical importance of evaluating LUTS in patients with sexual dysfunction, and the need to consider sexual issues in the management of patients with benign prostatic hypertrophy.

Sleep, fatigue, and medical training: setting an agenda for optimal learning and patient care.

The difficult issues surrounding discussions of sleep, fatigue, and medical education stem from an ironic biologic truth: physicians share a common physiology with their patients, a physiology that includes an absolute need for sleep and endogenous circadian rhythms governing alertness and performance. We cannot ignore the fact that patients become ill and require medical care at all times of the day and night, but we also cannot escape the fact that providing such care requires that medical professionals, including medical trainees, be awake and functioning at times that are in conflict with their endogenous sleep and circadian physiology. Finally, we cannot avoid the reality that medical education requires long hours in a constrained number of years. Solutions to the problem of sleep and fatigue in medical education will require the active involvement of numerous parties, ranging from trainees themselves to training program directors, hospital administrators, sleep and circadian scientists, and government funding and regulatory agencies. Each of these parties can be informed by previous laboratory and field studies in a variety of operational settings. including medical environments. Education regarding the known effects of sleep. circadian rhythms, and sleep deprivation can help to elevate the general level of discourse and point to potential solutions. Empiric research addressing the effects of sleep loss on patient safety, education outcomes, and resident health is urgently needed: equally important are the development and assessment of innovative countermeasures to maximize performance and learning. Addressing the economic realities of any changes in resident work hours is an essential component of any discussion of these issues. Finally, work-hour regulations may serve as one component of improved sleep and circadian health for medical trainees. but they should not be seen as substitutes for more original solutions that rely less on enforcement and more on collaboration. By working together to address the problems of sleep and fatigue in its own trainees, the medical field can provide a valuable legacy to patients and to future generations of healthcare providers--a legacy or optimal medical education, healthy doctors, and healthy patients.

Efficacy of tadalafil for the treatment of erectile dysfunction at 24 and 36 hours after dosing: a randomized controlled trial.

OBJECTIVES: To examine the therapeutic effects of tadalafil on erectile dysfunction (ED) at 24 and 36 hours after dosing. METHODS: A multicenter, randomized, double-blind, placebo-controlled, parallel-group study of 348 men (mean age 57 years) with ED was conducted in Europe and the United States. Patients were stratified by baseline severity of ED using the Erectile Function domain score of the International Index of Erectile Function and then randomly allocated within the severity group to receive tadalafil 20 mg (n = 175) or placebo (n = 173). Subsequently, participants were randomly assigned to two 4-week treatment intervals, during which they were requested to attempt sexual intercourse approximately 24 or 36 hours after tadalafil or placebo dosing. The primary outcome measure was the proportion of successful sexual intercourse attempts (completed to ejaculation) according to patient self-report using the Sexual Encounter Profile diary. RESULTS: Of the 348 patients, 327 (94%) completed the trial (163 of 175 in the tadalafil group and 164 of 173 in the placebo group). Thirty-six hours after tadalafil dosing, 59.2% of intercourse attempts were successful versus 28.3% in the placebo group (P <0.001). The proportion of successful intercourse attempts at approximately 24 hours after treatment was also significantly greater with tadalafil (52.9%) than with placebo (29.1%; P <0.001). Tadalafil was well tolerated. The incidences of four treatment-emergent adverse events were significantly greater in the tadalafil group than in the placebo group (all P <0.05): headache, flushing, dyspepsia, and myalgia. CONCLUSIONS: Tadalafil 20 mg is an effective and well-tolerated treatment for ED that has a period of responsiveness of up to 36 hours.

Erectile dysfunction in the cardiac patient: how common and should we treat?

PURPOSE: Risk factors for erectile dysfunction (ED) (hypertension, diabetes, smoking, lipid abnormality) are also risk factors for coronary artery disease. However, most cardiologists do not routinely ask about ED and patients often are reluctant or embarrassed to discuss it. We determined how common ED was in a group of patients with chronic stable coronary artery disease. MATERIALS AND METHODS: We administered the validated Sexual Health Inventory for Men (SHIM) 5-item questionnaire, based on the International Index of Erectile Function questionnaire, to 76 men with chronic stable coronary artery disease during routine outpatient cardiology visits. Most of these men had not previously discussed ED with their cardiologist. RESULTS: The mean patient age was 64 years (range 40 to 82). The questionnaire took about 5 minutes to complete. Of the patients 47% were on beta blockers, 92% statins, 28% diuretics. SHIM score was 21 or less in 53 men (70%), which is indicative of ED. Of the patients 75% had some difficulty achieving erections (question 2) and 67% had some difficulty maintaining an erection after penetration (question 3). The questionnaire reflected successful sildenafil treatment in 4 patients (SHIM scores 23 to 25). If these 4 men are included as having had ED then 57 of 76 (75%) had ED or recent history of ED. CONCLUSIONS: ED is extremely common in men with chronic coronary artery disease (affecting approximately 75%) yet most cardiologists do not ask about it. The SHIM is a useful, quick and inexpensive tool for discussion and diagnosis of ED in this population. Although it is well established that cardiovascular risk factors are associated with erectile dysfunction, once it is present there is mixed information on whether treating the risk factors will treat the ED. Problems appear to be that lifestyle modification in midlife may simply be too late to effect a change, and some antihypertensive and lipid lowering drugs may actually exacerbate ED. Oral therapy for ED, namely the PDE5 inhibitors, is effective and safe in most cardiac and hypertensive patients. Organic nitrates such as nitroglycerin remain a contraindication to the concomitant use of these drugs. Guidelines for treatment of ED in the cardiac patient issued by the American College of Cardiology/American Heart Association and Princeton Guidelines may be useful in the approach to the cardiac patient with ED.

Sleep loss and fatigue in residency training: a reappraisal.

Reduced sleep time is commonplace for many interns and residents. Recent studies, however, suggest that sleep loss and fatigue result in significant neurobehavioral impairments in healthy young adults. We reviewed studies addressing the effects of sleep loss on cognition, performance, and health in surgical and nonsurgical residents. We describe the effectiveness of countermeasures for sleepiness, including recent work-hour restrictions. A more complete understanding of the issues of sleep loss during residency training can inform innovative strategies to minimize the effects of sleepiness and fatigue on patient care and resident safety.

Female androgen insufficiency: the Princeton consensus statement on definition, classification, and assessment.

OBJECTIVE: To evaluate the evidence for and against androgen insufficiency as a cause of sexual and other health-related problems in women and to make recommendations regarding definition, diagnosis, and assessment of androgen deficiency states in women. DESIGN: Evaluation of peer-review literature and consensus conference of international experts. SETTING: Multinational conference in the United States. PATIENT(S): Premenopausal and postmenopausal women with androgen deficiency. INTERVENTION(S): Evaluation of peer-review literature and development of consensus panel guidelines. RESULT(S): The term "female androgen insufficiency" was defined as consisting of a pattern of clinical symptoms in the presence of decreased bioavailable T and normal estrogen status. Currently available assays were found to be lacking in sensitivity and reliability at the lower ranges, and the need for an equilibrium dialysis measure was strongly emphasized. Causes of androgen insufficiency in women were classified as ovarian, adrenal, hypothalamic-pituitary, drug-related, and idiopathic. A simplified management algorithm and clinical guidelines were proposed to assist clinicians in diagnosis and assessment. Androgen replacement is currently available in several forms, although none has been approved for treatment of sexual dysfunction or other common symptoms of female androgen insufficiency. Potential risks associated with treatment were identified, and the need for informed consent and careful monitoring was noted. Finally, the panel identified key goals and priorities for future research. CONCLUSION(S): A new definition of androgen insufficiency in women has been proposed along with consensus-based guidelines for clinical assessment and diagnosis. A simplified management algorithm for women with low androgen in the presence of clinical symptoms and normal estrogen status has also been proposed.

Depression, antidepressant therapies, and erectile dysfunction: clinical trials of sildenafil citrate (Viagra) in treated and untreated patients with depression.

Erectile dysfunction (ED) and depression are highly prevalent conditions and frequently occur concomitantly in predisposed individuals. Men with ED and depression are also likely to have other comorbid conditions, including diabetes, hypertension, and heart disease. Because ED is also a common adverse effect of some medications for these conditions, patients are frequently noncompliant with treatment. Sildenafil citrate (Viagra) is effective in treating ED of a broad range of etiologies, suggesting that it may be equally beneficial in patients with ED that is associated with depressive symptoms and in those with ED resulting from serotonergic reuptake inhibitor (SRI) antidepressant treatment. We review the results of 3 randomized, placebo-controlled trials and a retrospective analysis of data pooled from 10 clinical trials that examine the efficacy of sildenafil in treating ED associated with depression and as an adverse effect of SRI treatment. The results suggest that sildenafil is efficacious as a first-line treatment for ED in men with untreated minor depression, in men with ED that is refractory to successful SRI treatment of depression, and in those whose depression was successfully treated but who developed ED as a consequence of SRI treatment. Given the complex interrelations among ED, depression, and other comorbid conditions, the key to proper management is a comprehensive evaluation, including sexual function, and an accurate differential diagnosis.

Health care clinicians in sexual health medicine: focus on erectile dysfunction.

A consensus guidelines model was developed for managing erectile dysfunction (ED) by urology nurses and other health care clinicians. The model emphasizes identification of ED in all males older than 40, education and counseling as keys to intervention, and inclusion of partners whenever possible. These guidelines are intended to provide a comprehensive care model for ED patients and their partners, which would be optimally cost effective and clinically relevant. If successful, this new model will allow quality sexual health care to be provided to increasing numbers of patients and their partners.

The Female Sexual Distress Scale (FSDS): initial validation of a standardized scale for assessment of sexually related personal distress in women.

Recent consensus-based characterizations of female sexual dysfunction have emphasized personal distress as an essential component of their definition. To assist researchers and clinicians, we developed a new scale, the Female Sexual Distress Scale, to measure sexually related personal distress in women. In this article, we describe the initial stages in the development and validation of this instrument. Three studies involving a total of approximately 500 women were performed to evaluate the reliability and validity of the scale in different samples of sexually functional and dysfunctional women. Results indicated a unidimensional factor structure in both the original 20-item version and in a "polished" 12-item version. We observed a high degree of internal consistency and test-retest reliability in both versions across all three studies. Additionally, the scale showed a high degree of discriminative ability to distinguish between sexually dysfunctional and functional women in each of the studies. One study also showed a strong sensitivity to treatment response. Finally, we observed moderate positive correlations with other conceptually related nonsexual measures of distress, supporting the construct validity of the scale. Overall, these findings provide solid support for the FSDS as a valid and reliable measure for assessing sexually related personal distress in women.
