Erectile dysfunction (ED) has been defined by the National Institutes of Health Consensus Conference in 1993 as the inability to achieve and/or maintain an erection adequate for penetration and completion of satisfactory intercourse.1 Erectile dysfunction, the preferred term, is more accurate and less pejorative than impotence.An estimated 20-30 million American men are affected with ED of varying degrees of severity. The Massachusetts Male Aging Study published in 1994 reviewed 1,211 men between the ages of 40 and 70; 52% reported ED with 9.6% having mild, 22.2% moderate, and 17.2% complete or severe ED.2 The National Health and Social Life Survey, authored by Laumann et al.,3 reviewed a population of men and women between the ages of 18 and 59. Of note, female sexual dysfunction exceeded male sexual dysfunction, with 43% of women complaining of sexual function problems. Interestingly, except for lubrication, this seemed to decrease with age in women. On the other hand, 31% of the men complained of sexual problems that increased with age.Erectile dysfunction is an age-dependent problem. Approximately 2% of men are affected at 40 years of age and about 25% or more at 65 years of age.4 However, ED is not an inevitable result of aging. Rather, as a man matures it is most likely that he will experience more of the neurovascular insults resulting in ED.The development of an erection and satisfactory sexual function is a complex process. As suggested by Melman et al.,5 "Erection is truly at least a sensory-motor-neuro-hormonal-vascular-psycho-social-cultural-interpersonal event." There are two main classifications of ED, psychogenic and organic. Current thinking suggests that up to 80% of ED is primarily of organic etiology. Yet, there is always a psychogenic factor.6 Erectile dysfunction may signal serious underlying and potential life-threatening diseases, such as diabetes, hypertension, cardiovascular disease, peripheral vascular disease, and other neurologic and endocrine disorders. Therefore, questions regarding sexual function should be part of routine medical evaluation.

In 169 patients visiting our department complaining of sexual dysfunction, the medical history was taken using a semistructured interview. A clinical investigation and a hormone analysis were added. The age of patients, hormone values, and items of the interview were collected into a common database. The items were categorized as either dichotomous (yes/no) or ordinal. Statistical analysis was performed using regression analysis with the aim to generate hypotheses of relations. An increase of FSH levels and a decrease of testosterone levels with age occurred. None of the relations of hormone levels or diseases to symptoms of sexual dysfunction produced odds ratios (OR) statistically significant different from 1. However, the risk of having a reduced libido and reduced morning erections was lower in psychoneurological diseases, the risk of reduced arousal and libido was lower in men with diabetes mellitus, but the risk of reduced morning erections was higher in these men. The testosterone levels were not associated with the risk of having reduced penile rigidity, duration of erection, arousal and sexual libido, reduced morning erections and the ability to masturbate. Smoking was not associated with reduced arousal, libido and morning erections. However, a significant increase of testosterone levels with number of cigarettes used was observed. We conclude that sexual dysfunction in patients visiting an andrological department for diagnosis and treatment is mostly not associated to any single evaluable factor.

Correlation interrelations between indices for SMF (sexual formula male proper) were studied together with values for testosterone in blood serum and testosterone-estradiol relations in 63 male subjects presenting with sexual problems of various genesis. No correlation was established between blood serum testosterone levels or testosterone-estradiol relations as well as between SMF indices characterizing the state of libido and erection both in cases of psychogenic sexual dysfunction and in those precipitated by prepubertal hypogonadism, insulin-dependent diabetes mellitus, and chronic prostatitis. It is only in those cases of the above-mentioned dysfunction related to chronic prostatitis that there exists a positive correlation between testosterone-estradiol ratio and SMF index characterizing ejaculation.

Although Black end-stage renal disease (ESRD) patients on dialysis report better functioning and well-being than do White patients, little is known about the association of race with disease symptoms and treatment side effects. Interviews were conducted with 183 older Black and 125 older White in-center hemodialysis (HD) patients in Georgia. Patients were identified in a stratified (by race and sex) random sample of patients aged 60+ years selected from the ESRD Network census of all patients in that age category. Self-assessed disease symptoms and/or side effects of treatment, disability days, and health satisfaction were measured. Data were analyzed via logistic or linear regression, controlling for the effects of patients' gender, age, months on dialysis, primary diagnosis of diabetes, cardiovascular co-morbidity, HD treatment time, and usual interdialytic weight gain. Older Whites, compared to older Blacks, were at increased risk for reporting nausea, sexual dysfunction, recent bed disability days, fatigue, greater HD recovery time, and health dissatisfaction. The relation of these complaints to dialysis adequacy and patients' nutritional status merits continued study.

This article presents and evaluates the symptoms, presentation, diagnosis, and treatment of men with interstitial cystitis (IC). A retrospective chart review and an interview of all men in our practice diagnosed with IC since 1990 was performed. The patients' presenting symptoms, physical findings, clinical evaluation, and responses to therapy were reviewed. A total of 52 men were identified during the study who met the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) criteria for diagnosis of IC. The most common referral diagnosis was prostatitis with the most common predominant symptoms being suprapubic pain with urinary frequency and dysuria. A significant number of male patients also developed sexual dysfunction. All patients met the NIDDK criteria for a diagnosis of IC. Multiple therapies were used for the treatment of these patients over the study period. Five patients were initially treated with dimethyl sulfoxide (DMSO) as a sole agent; however, all intravesically treated patients eventually failed this form of therapy. A total of 37 of 52 patients were treated with multidrug oral therapy. Findings showed that 80% of patients achieved >75% improvement in their symptomology at 6 months of follow-up with a durable response at 1 year. IC in men is probably underdiagnosed and is most commonly misdiagnosed as prostatitis. The patient's presentation is analogous to that in the female population allowing for gender differences. The patients responded well to multidrug oral therapy.

The incidence of diabetes mellitus is increasing at an alarming rate, and diabetic men already make up a quarter of the men in our own specific medically-oriented population of erectile dysfunction. The incidence of sexual dysfunction in men with diabetes approaches 50%, and this is only slightly lower in diabetic women. Hypertension is a frequent risk co-factor, being seen between 40% and 60% of diabetics in the literature. Obesity and hyperlipidemia are other frequent co-factors. Interestingly, these risk factors are the same as those for coronary artery disease. The final common pathway for most of these factors is endothelial cell dysfunction.

Diabetes Mellitus frankly increases the prevalence of sexual problems in men, mainly in the form of erectile dysfunctions. Its effects on sexual function of the diabetic women have been less objectively studied, due to cultural reasons and methodological difficulties. The different phases of the sexual cycle, as well as their physiological control, are similar in human males and females. Several studies suggest an increased prevalence of sexual problems also in diabetic females. Their rate seems similar to that of the males. An increased prevalence of Female Sexual Arousal Disorder has been found in 6 studies of 6 comparing diabetic to non diabetic females. Its main symptom was a deficient vaginal lubrication, making sexual intercourse unpleasant. This disorder is the female equivalent to erectile dysfunction. It probably results from similar mechanisms, involving damages in the vascular and autonomic nervous systems, as well as alteration in the nitric oxide production and efficacy. The prevalence of Hypoactive Sexual Desire Disorder was also increased in most studies (5 of 8, significantly in 3). This could result from the increased prevalence of depression in diabetic females. The Dyspareunia's prevalence was not significantly increased (0 of 6 studies). Available figures are not consistent as regards the orgasmic disorders (prevalence increased in only 4 of 8 studies). No significant correlation of female sexual dysfunction with diabetes duration, balance, or complications has been found. Conversely some significant correlations with depression or poor acceptance of diabetes have been found, supporting a causative role of psychological factors. Although still limited the therapeutic options should not be neglected. Merely prescribing a water soluble lubricating gel may greatly improve the sexual life of couples. Doctors should talk themselves about sexual function with their female diabetic patients. Most of these are too much embarrassed to ask themselves their doctor, although their sexual problems may seriously interfere with their quality of life and that of their partner.

Diabetes Mellitus (DM) is considered to play a principle role in the etiopathogenesis of sexual dysfunction both in men and women. The aim of this study is to evaluate sexual function in Type II diabetic women. A total of 72 young diabetic women (mean age: 38.8 years) with no other systemic diseases and 60 age-matched healthy women were enrolled in our study. We sought from them a detailed medical and sexual history and used the Index of Female Sexual function (IFSF) questionnaire (Kaplan et al., 1999). The mean IFSF score of diabetic women was 29.3 +/- 6.4 and was 37.7 +/- 3.5 in normal cases (p < 0.05). Lack of libido was the most common symptom in diabetics and was observed in 77% of the women. Diminished clitoral sensation was observed in 62.5% of the women, 37.5% complained of vaginal dryness and 41.6% had vaginal discomfort. Orgasmic dysfunction was found in 49% of the women. The incidence of all these related symptoms were significantly higher when compared to controls. We concluded that significant percentage of diabetic women that we observed experience sexual dysfunction of varying degrees that diminishes their quality of life.

In order to evaluate the erectile function in male renal failure patients treated with hemodialysis (HD), we investigated the International Index of Erectile Function (IIEF) in patients and healthy controls. The subjects were 174 male patients treated with HD, of whom 43 had diabetes mellitus (DM) and the remaining 131 patients did not have DM. The controls were 1133 healthy males. We evaluated the prevalence of erectile dysfunction (ED) using the erectile function (EF) score, which is one of the five domains of the IIEF, in each age group (upto 39 y old, 40-49 y old, 50-59 y old, 60-69 y old). The severity of ED was classified into five categories using EF in each age group. The univariate logistic regression analysis and multiple variate analysis of IIEF in HD patients were performed. The prevalence of ED in HD patients was significantly higher than that in the controls in each age group. The severity of ED in HD patients was also significantly higher than that in the controls in each age group. In the logistic regression analysis and multiple variate analysis of IIEF in HD patients, DM and age were significant risk factors on sexual dysfunction. ED was more prevalent in male renal failure patients treated with HD than in the controls. In the patient group, ED was more prevalent in older DM patients.

Issues to consider when evaluating maintenance drug therapy for patients with schizophrenia are discussed; these include potential adverse effects of antipsychotic therapy, such as weight gain, diabetes mellitus, extrapyramidal symptoms, sexual dysfunction, cognitive dysfunction, and cardiac effects, as well as quality of life. Patients with schizophrenia are more likely to be overweight than the general population. Olanzapine and clozapine have been associated with the greatest weight gain of the newer antipsychotics. While patients with schizophrenia are at increased risk of developing diabetes mellitus independent of antipsychotic therapy, diabetes may be more prevalent in patients taking the newer agents. Acute extrapyramidal symptoms occur in 75-90% of patients receiving first-generation antipsychotics like thioridazine and haloperidol. The probability of tardive dyskinesia (TD) occurring with second- and third-generation agents is less than 1% per year, compared with about 5% per year for the traditional antipsychotics. When patients are switched from a traditional antipsychotic to clozapine or olanzapine, TDs usually abate somewhat. Thioridazine causes a pronounced prolongation of the QTc interval, which can lead to ventricular arrhythmias. The slight increase in QTc interval caused by ziprasidone most likely will not be a problem in healthy individuals. Newer antipsychotics are associated with improved neurocognitive functioning and most cause less prolactin elevation, compared with traditional agents. The newer antipsychotic agents are not devoid of adverse effects, but those that do occur can be managed. Once issues related to adherence are resolved, rehabilitation of patients with schizophrenia will be a high priority.
