Streptozotocin-induced diabetes mellitus causes diuresis, increases in bladder mass and changes in micturition. Temporal changes in micturition and bladder mass after induction of diabetes with streptozotocin were monitored and correlated with DNA synthesis and 3H-thymidine incorporation. There were increases in water consumption, urine excretion, urinary frequency, and mean and maximal micturition volume within 1 day after induction of diabetes. These parameters reached maximal values within 6 to 11 days and were maintained at 30 and 60 days. Bladder mass was significantly elevated by 7 days and did not increase further with increasing duration of diabetes. DNA concentration was decreased in bladders from 4, 7 and 14 day diabetics. 3H-thymidine incorporation into DNA increased within 2 days after induction of diabetes, reached maximal values at 4 to 7 days and declined to control values by 14 days. Autoradiography showed intense labelling of the urothelium one day after induction of diabetes, with labelling remaining high up to day 7. Connective tissue and smooth muscle labelling were slower to develop. Labelling of smooth muscle was transient, appearing only on days 4 and 7. The time course of the events was consistent with the hypothesis that bladder distension or increasing micturition volume stimulates thymidine incorporation into DNA, resulting in an increase in bladder mass.

17 cases of patients with diabetes mellitus who had urinary frequency symptom for which anti-cholinergic agents proved ineffective were given Sarpogrelate Hydrochloride (Anplag), a selective 5-HT 2 receptor antagonist. Efficacy was judged using IPSS and QOL scores after 2 weeks medications, these showed that all cases had improved their urinary frequency during the days as well as the night. This was especially true for the QOL score. One time urinary volume markedly increased, but there was no statistical significance after medication in maximum flow rate and residual urine. At the same time, a separate group of 14 mainly BPH cases did not improve entirely. It is believed that reaction in the detrusor muscle with hyperreflexia of diabetes mellitus patients can reach 5-HT, and its reaction is believed to reach via the 5-HT 2 receptor. This paper is a first clinical report of making use of 5-HT 2 antagonist as hyperactive detrusor on diabetes mellitus patients.

A retrospective study was performed to determine the proportion of dogs with hyperadrenocorticism or diabetes mellitus or both that had urinary tract infection (UTI) and to describe clinical and laboratory findings. Dogs with these endocrine disorders were included if results of quantitative urine culture were available and dogs were not receiving antimicrobials. Dogs with positive urine cultures were considered to have UTI and dogs with negative urine cultures were used as controls. Information including history, clinical signs, physical examination findings, and results of laboratory tests and urine culture was extracted from all records. Findings in dogs with UTI were compared with control dogs. There were 101 dogs with hyperadrenocorticism or diabetes mellitus or both that met inclusion criteria; 42 (41.6%) had UTI and 59 (58.4%) did not. UTI was present in 46% of dogs with hyperadrenocorticism, 37% of dogs with diabetes mellitus, and 50% of dogs with both endocrine disorders. There was no association between endocrine group and occurrence of UTI. Escherichia coli was the most common bacteria isolated, and cultures from 29 dogs (69%) showed growth of this organism. Of dogs with UTI, <5% had stranguria, pollakiuria, or discolored urine, whereas 60% had pyuria and 69% had bacteriuria. We conclude that UTIs are common in dogs with hyperadrenocorticism, diabetes mellitus, or both diseases. Clinical signs of UTI, however, are uncommon and results of urinalysis may be normal. Therefore, it is appropriate to recommend urine culture as part of the evaluation of dogs with these endocrine disorders.

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.

Very few epidemiologic studies of interstitial cystitis (IC) have been published over the past 5 years. One population-based study focused only on women and suggested that the prevalence of the IC symptom complex in the United States is much higher than previously reported. Future epidemiologic studies of IC must overcome major obstacles to obtain more accurate population-based estimates. The National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) criteria used to assist in identifying patients with IC have proven to be cumbersome and too restrictive. Other obstacles include (1) the relative infrequency of the condition; (2) the long duration between development of symptoms and diagnosis; and (3) the perception that the disorder occurs predominantly in white women. Evidence suggests men with the IC symptom complex are often misdiagnosed by physicians and identified as having chronic prostatitis (also called the chronic pelvic pain syndrome) or benign prostatic hyperplasia. Children who present with the IC symptom complex are often thought to have voiding dysfunction. We propose that the more inclusive, less restrictive term chronic pelvic pain of the bladder (CPPB) be used in future epidemiologic studies of persons with the characteristic IC symptoms of urinary frequency, urgency, and pain. Early studies of chronic pelvic pain in general suggest that it is most common in women, of unknown etiology, and, in many patients, is associated with urinary bladder symptoms. It is necessary to develop case definitions for CPPB to accurately identify those patients with symptoms currently identified as IC.

Interstitial cystitis (IC) is a chronic condition characterized by a constellation of symptoms such as urinary frequency, nocturia, urinary urgency, suprapubic pressure, and bladder and pelvic pain. Since its original description, the etiology of the disorder has remained unknown despite intense investigations. The International Cystitis Association (ICA) and the National Institutes of Arthritis, Diabetes, Digestive and Kidney Diseases (NIDDK) have been instrumental in supporting the United States Interstitial Database (ICDB) and foster research to study the disorder. The NIDDK developed criteria to ensure that all groups of patients treated would be relatively comparable. However, many patients who would be clinically considered to have IC do not fulfill all the NIDDK criteria. Many clinical criteria for the diagnosis of IC, such as the presence of glomerulations and the intravesical potassium chloride test, are being challenged. The epidemiology of the disorder is not well established, but there are an estimated 700,000 cases of IC in the United States. Numerous pathophysiologic mechanisms have been proposed, but none have been proven. There is no representative animal model of IC. Both the oral and intravesical treatments of IC are noncurative, and few are based on a plausible mechanism or scientific evidence. Surgical treatment should be considered with extreme caution; it is the last therapeutic option because failure rate can be substantial.

Drugs acting on beta(1)- and beta(2)-adrenergic receptors are widely used for the clinical management of a large number of cardiovascular and respiratory pathologies. In the last decade, the discovery of the third subtype of beta receptors, the beta(3)-adrenoceptor, gave a further pharmacological target for the development of new selective drugs. Initially, a potential therapeutic use of beta(3)-selective agents seemed to be restricted to agonists, for the treatment of metabolic diseases, such as obesity, non-insulin-dependent diabetes, urinary frequency and incontinence. More recently, some interesting theories about a negative role played by the cardio-depressant activity of myocardial beta(3)-adrenoceptors in heart failure, seemed to justify a clinical use of beta(3)-antagonists in the last phases of this cardiac disease. Following the indications deriving from previous experimental work, the beta-antagonist properties of newly-synthesised (R,S)-(E)-oximeethers of 2,3-dihydro-1,8-naphthyridine and of 2,3-dihydrothiopyrano[2,3-b]pyridine were evaluated, in order to identify some useful structure-activity relationships, which might account for selectivity towards the three beta-subtypes and, in particular, the beta(3)-adrenoceptor. Among the various observations regarding possible structure-activity relationships, able to explain the pharmacodynamic patterns of the synthesised compounds on the three subtypes of beta-adrenoceptors, the most significant data derived from the evaluation of the beta(3)-blocking properties of some oximeethers of 1,8-naphthyridine derivatives. In these molecules, although the presence of the large substituents in position 7, such as 4-chloro-phenoxy- or 4-t-butyl-phenoxy groups determined a dramatic decline in both the beta(1)- and beta(2)-activities, this structural characteristic had a modest influence on the beta(3)-affinity, which was only slightly lower. Hence, this last structural requirement of oximeethers of 1,8-naphthyridine derivatives seems to represent a useful expedient to induce an appreciable selectivity towards the beta(3)-receptor, through a markedly negative effect on the beta(1)- and beta(2)-activities rather than an increase in the beta(3)-affinity.

The purpose of this study was to analyze the transrectal ultrasound (US), or TRUS, and color Doppler ultrasonography (CDU) findings and therapeutic strategies with TRUS-guided procedures in 13 patients with prostatic abscess. Over a period of 6 years, 18 prostatic abscesses were diagnosed in 13 patients (mean age: 59 years). Diagnostic workup included TRUS, analysis of midstream urine, and analysis and culture of abscess fluid for leukocytes and pathogens. These patients were treated either conservatively (for abscess cavities < 1 cm in diameter), or by aspiration or draining procedures (cavities > or = 1 cm). The transrectal CDU findings were correlated to the treatment effects. The predisposing factors were also reviewed. In the 13 patients, the most common clinical symptom and sign were urinary frequency (77%) and pus cell in the midstream urine (92%). Predisposing factors were found in 11 men, with diabetes in 5 of them. In 10 patients, the definitive preinterventional diagnosis was based on the TRUS findings. TRUS with probe palpation demonstrated tiny floating echogenic speckles in the abscess cavity in 4 patients. CDU demonstrated increased color-flow signals at the margin and surrounding tissue of the abscess pockets. Abscesses with poorly defined boundaries had more prominent surrounding color-flow signals and achieved, with relative difficulty, a satisfactory aspiration procedure. Aspiration was done for all 11 abscesses between 1 and 3 cm. A total of 4 larger abscesses (> 3.0 cm) were treated with aspiration or drainage using a 5-French pigtail catheter. No surgical drainage was performed. Transrectal CDU may help in the evaluation of maturity of an abscess pocket. US-guided aspiration with an 18-gauge needle or drainage with a 5-French pigtail catheter significantly shortened the hospital stay.

Interstitial cystitis is a chronic, heterogeneous syndrome that is characterized by the classic symptoms of bladder pain, nycturia, and pollakiuria. Population studies have shown an increase in prevalence and incidence. Different hypotheses exist about the etiology and pathogenesis. Epithelial dysfunction and neuro-urothelial interaction are the most frequently used causal models. Utilization of the official diagnosis criteria of the NIDDK (National Institute of Diabetes, Digestive and Kidney Disease) should be flexible and individual in order not to overlook early forms of IC. Since there is no pathognomonic marker, diagnosis of IC is a combination of typical patient history and exclusion of differential diagnoses. Cystoscopy and biopsies are not specific; however, they can provide useful information on extent and aid in treatment choice. The effectiveness of conservative therapy has been increased by using electromotive drug administration (EMDA) in instillation therapy.

The University of Kentucky Center for Rural Health original research note, "Kentucky Homeplace Defeat Diabetes Screening Test: An Analysis of Rural Kentucky's Challenge to Overcome the Growing Diabetes Epidemic," provides the results of a yearlong diabetes risk survey that included more than 3,000 participants in rural Kentucky. It is well known that diabetes poses serious health threats across our country. For various reasons, that is especially true in Kentucky, with rural Kentucky having the highest prevalence for the disease. From September 2002 through August 2003, lay health workers with the nationally recognized Kentucky Homeplace program distributed and processed 3,092 diabetes self-test surveys to their clients across five regions of the state to get a better picture of the diabetes epidemic. The screening test was developed as an educational and public awareness tool by the Defeat Diabetes Foundation Inc, a nonprofit organization based in Madeira Beach, FL. It was distributed to various health agencies across the country. Each survey contained 16 questions, ranging from determining participants' urinary frequency and family medical history to their age and weight. Zero, five, or 10 points were allotted depending on respondents' degree of incidence for each question. A score of 0-15 points suggested a low risk for having diabetes, 20-25 points suggested that a respondent was at medium risk and should be tested for the disease, and a score of 30 points or higher suggested that he/she was at very high risk and "should seek (a) medical evaluation right away." Several months of analysis of the data collected indicated that 74.6% of the Kentucky Homeplace clients who participated in the survey were at moderate to significant risk of having or developing diabetes, a much higher rate than the approximately 50% of Kentucky adults in the general population that previous studies indicated were at risk. While findings from the survey of more than 3,000 Kentucky Homeplace clients cannot be generalized to Kentucky's population as a whole, they further confirm other evidence indicating that diabetes will continue to be one of the most serious health threats facing the state's rural populations. The research note further offered some recommendations for curbing rural Kentucky's diabetes epidemic, including increasing the number of certified diabetes educators serving rural Kentucky, expanding lay health worker programs within the rural portions of the Commonwealth, and studying the method and effectiveness of diabetes education between physicians and patients.
