Massive obesity is associated with serious co-morbidities. After failure of extensive conservative measures, surgical procedures have developed as the only successful method for sustained weight loss. Criteria for operation are: presence of serious diseases associated with morbid obesity; greater than 45 kg above ideal weight or body mass index greater than 40 kg/m2 for usually greater than 5 years; failure of sustained weight loss on extensive conservative regimens; commitment to lifelong follow-up; and acceptable operative risk. Angina pectoris itself is not a contraindication to these operations. Patients who do not quite meet the weight criteria may still be candidates for an obesity operation in certain instances, e.g., debilitating musculoskeletal pains in weight-bearing joints, diabetes, significant hypertension, reflux esophagitis, urinary stress incontinence. Although current operations result in lasting weight loss of greater than 50% of excess weight in the majority of patients, the surgical candidate must understand and accept the principles of the procedures, the potential for serious complications, the dietary necessities, and occasional failures.

A 65-year-old woman started taking enalapril 2.5 mg daily for hypertension. Twelve days later she complained of a persistent, dry cough. Due to the coughing and a preexisting cystocele, she developed stress incontinence and a marked decline in her functional status. The coughing and incontinence resolved with the discontinuation of enalapril. During a subsequent hospitalization the patient received captopril 6.25 mg twice daily for congestive heart failure. Within 24 hours the dry cough recurred. It resolved with the discontinuation of the drug. Cough is a symptom that is generally not recognized as a drug side effect. However, increasing numbers of case reports document angiotensin-converting enzyme inhibitor-induced cough. Although the actual frequency and mechanism are currently unknown, the dry cough typically begins early in the course of therapy. It may be specific to this pharmacologic class rather than to one individual agent. Age and sex may be contributing factors. While cough has been considered a minor side effect, unnecessary hospitalizations and inappropriate treatments may easily result. Even minor adverse reactions may have an impact on a patient's quality of life.

A clinical study was undertaken to assess gynecologic-obstetric changes in morbidly obese women who lost greater than or equal to 50% of their excess weight with bariatric surgery. The 138 females (109 of reproductive age), age 35 +/- 9 SD yr, weighed 124 +/- 23 kg before surgery and 79 +/- 13 kg after weight loss had stabilized. Menstrual irregularities were present in 40.4% of premenopausal patients preoperatively; after massive weight loss, cycles were abnormal in 4.6% (p less than 0.001). Infertility problems were present preoperatively in 29.3% Of these, nine tried to conceive after weight loss and were successful. During past pregnancies, medical complications were frequent (hypertension 26.7%, pre-eclampsia 12.8%, diabetes 7.0%, and deep vein thrombosis 7.0%). After weight-loss stabilization, these obstetric complications did not occur. Incidence of urinary stress incontinence decreased from 61.2% to 11.6% (p less than 0.001). Gynecologic-obstetric changes tended to normalize after loss of massive body weight.

Applying the basic principles, therapy guides to our hypothetical cases can be constructed. The 60 year old man with postoperative abdominal perineal resection with hypertension and parkinsonism may well need a transurethral resection of the prostate; however, other options include decreasing his anticholinergic-type medications, such as antiparkinsonism medications, changing his hypertensive therapy from beta blockers such as propranolol and metoprolol to alpha blockers such as methyldopa and prazosin. Bethanacol would seldom be helpful alone, but with an alpha blocker could help if not contraindicated by the presence of vascular disease. The second example, a 45 year old woman with stress incontinence, may be assisted with improved storage by an anticholinergic agent, an alpha enhancer, a mucosal enhancer, and if pertinent, switching hypertensive therapy from an alpha blocker to a beta blocker. The last example, a T10 paraplegic with a spastic, hyperreflexic bladder, can have improved storage with anticholinergics, decreased sphincter tone with alpha blockers, as well as decreased sphincter tone with alpha blockers, as well as decreased spasms through suppression of hyperactive spinal cord activity with baclofen.

Genital prolapse is associated to a greater concurrence of repeat urinary infections, stress urinary incontinence, arterial hypertension and obstructive uropathy with a higher or lower degree of renal impairment. Incidence of uropathy in the genital prolapse setting ranges between 4 and 13%. This paper presents a female patient with renal insufficiency secondary to bilateral obstructive uropathy caused by a concomitant genital prolapse. A brief revision is made of the pathophysiological, diagnostic and therapeutic aspects in the literature. The need to perform both prone and standing urographic studies is emphasized; also a study of the renal function should be performed in these patients in order to establish the appropriate treatment and avoid major complications and renal function impairment.

The authors retrospectively evaluated 1,773 climacteric outpatients in order to establish: (a) criteria able to distinguish different conditions in the transitional phase before menopause (advanced fertile age and premenopause) and (b) premenopause-related changes during the transition from one to the other of several clinical and laboratory parameters. Results showed an increase in gonadotropin plasma levels, a decrease in estrogen plasma levels and a greater frequency of women complaining of hot flushes in premenopause compared to advanced fertile age, as an expression of the progressive decline of ovarian function. Premenopause-related changes were a decrease in thyroid function and an increase in the body mass index, the beginning of bone loss, an increase in glucose, total cholesterol and triglyceride serum levels and a greater frequency of women complaining of hypertension and urinary stress incontinence. An increase in total proteins, uric acid and aminotransferase serum levels was also noted.

There have been occasional reports of female stress incontinence related to prazosin therapy for hypertension. This drug is now rarely used but recently longer acting alpha-adrenoceptor blocking drugs have been introduced. We have, therefore, investigated the prevalence of urinary incontinence in all our female patients who were receiving alpha-adrenoceptor blockers in comparison with women, matched for age and parity who were receiving other drugs. We identified a total of 49 women taking alpha-adrenoceptor blocking drugs (prazosin 4, terazosin 5, doxazosin 40) among current patients who were attending our hypertension clinic. Twenty of these (40.8%) reported some urinary incontinence whereas in the control patients, only 8 (16.3%) had this symptom (P = < 0.02, relative risk 2.5, 95% CI 1.22-5.13). alpha-Adrenoceptor blockers were withdrawn in 18 of the 20 patients with incontinence and in 13, their symptoms abated. Our results suggest that there is a significantly higher prevalence of urinary incontinence in women taking alpha-adrenoceptor antagonists with reversibility on withdrawal of these drugs. As both female urinary incontinence, hypertension and the use of alpha-adrenoceptor blocking drugs are common, this distressing side effect should be borne in mind so that gynaecological or urological treatment may be avoided in some women.

Women's healthcare issues have become increasingly important. Specific healthcare issues, including management of high blood pressure, obesity, and menopause have been on the forefront for years. Today, urinary incontinence in women of all ages is seen as a major healthcare concern. The impetus for this increased awareness began in 1988 at the National Institutes of Health Consensus Conference on Adult Urinary Incontinence, which was followed by the publication of the Guideline for Adult Urinary Incontinence by the Agency for Health Care Policy and Research in 1992. Since that time, there has been an increased focus on the problem of urinary incontinence. Many hope that more women will seek professional guidance for the evaluation and management of urinary incontinence as a result of this increased awareness. Healthcare professionals need to be current on the various options available for the management of urinary incontinence, particularly stress urinary incontinence, as it commonly affects women.

The subdivision of alpha adrenoceptors into the alpha 1 and alpha 2 classes was the impetus for the design of the selective alpha 1-adrenoceptor antagonists, which remain useful antihypertensives. alpha 2-Adrenoceptor agonists also have application as antihypertensive drugs, based on their ability to reduce sympathetic outflow. Likewise, subdivision of the beta adrenoceptors has lead to the development of selective beta 1-adrenoceptor antagonists as antihypertensive and selective beta 2 agonists as bronchodilators. In the past decade, both the alpha 1 and alpha 2 adrenoceptors have been further subdivided, each into three subclasses. In addition, there is strong functional evidence to suggest the presence of additional adrenoceptor subtypes, such as the "alpha 1L" adrenoceptor and "beta 4" adrenoceptor. alpha 1A (or alpha 1L)-Adrenoceptor antagonists have been evaluated for benign prostatic hyperplasia (BPH), and selective alpha 1A agonists for stress incontinence. Gene knockout experiments in mice suggest an important role for the alpha 1B adrenoceptor in the control of vascular tone. Hence, selective alpha 1B antagonists may offer a new approach toward hypertension. Although targeting of specific adrenoceptors can be used to optimize the therapeutic profile of a drug, there are also cases where blockade of multiple adrenoceptors is desirable, as with the alpha/beta-adrenoceptor antagonist carvedilol in congestive heart failure. It is possible that combination of affinities for selected adrenoceptor subtypes within a single molecule may be desirable for certain applications.

The pharmacological effect of amezinium on the urethra and bladder of rabbits was investigated. Amezinium produced concentration-dependent contractions in isolated urethral strips. The maximum response was approximately 30% of that caused by norepinephrine (NE). The concentration-response curve of NE was shifted to the left by amezinium. Moreover, amezinium enhanced the relaxative effect of NE on carbachol-induced contractions in isolated bladder strips. In anesthetized rabbits, amezinium significantly increased the intraurethral pressure (IUP) but produced only slight increases in mean blood pressure (MBP). Pre-treatment with amezinium ehhanced NE-induced increases in IUP index and MBP. The enhancing effect on the IUP index lasted much longer than that on MBP. In a stress incontinence model amezinium significantly inhibited the incontinence after an i.v. infusion of a low dose of NE. This effect was antagonized by pre-treatment with prazosin. These results suggest that amezinium may produce an excellent effect for stress incontinence, especially mixed, without severe adverse events such as sudden hypertension.
