As electrical stimulation of the rectum has been shown to result in reflex internal sphincter inhibition mediated by intrinsic nerves, we aimed to evaluate the integrity of these nerves in the rectum of diabetic patients. Anal canal pressure, recto-anal inhibitory reflex (RAIR) and continence were evaluated in 30 diabetic patients (male:female 13:17, median age 57 years, range 37-70) and these data were compared with similar data obtained from 22 age- and sex-matched healthy controls (male:female 9:13, median age 51 years, range 19-65 years). Median duration of diabetes was 8 years (range 3-30). Twelve (40%) of the 30 diabetics had impaired continence for gas (n = 12) and liquid faeces (n = 3). None of the controls had incontinence. Median maximum resting anal canal pressure (MRP) was: patients 30 mmHg (range 20-75 mmHg) versus controls 40 mmHg (range 20-105 mmHg, P = 0.61). Median maximum squeeze pressure (MSP) was 65 mmHg (range 30-150 mmHg) in patients versus 84mmHg (range 35-230 mm Hg) in controls (P = 0.59). Median threshold rectal mucosal electrosensation (RMES-T) was 27mA (5-40 mA) in patients versus 13 mA (5-28 mA) in controls (P = 0.03). Maximum tolerable rectal mucosal electrosensation was 40 mA (20-60) in patients versus 20 mA (10-30), in controls (P = 0.042, all comparisons using the Wilcoxon rank test). Recto-anal inhibitory reflex was present in eight, abnormal in five (one incontinent) and absent in 17 (11 incontinent) diabetics, while it was present in 18 and abnormal in four controls (test of proportion, P = 0.031). Blood glucose in diabetics on the day of the procedure was 98 mg/dL (70-165 mg/dL). Rectal mucosal electrosensitivity and RAIR were impaired in significantly more patients with diabetes than controls, implying impairment of intrinsic neuronal function. The recto-anal inhibitory reflex was either impaired or absent in all diabetic patients with incontinence.

Pressure ulcers remain a common medical problem in nursing homes, despite the development of clinical guidelines for prevention and treatment. Prevention involves low technology but vigilant care. If the disease progresses, infections can develop, and surgery may be necessary to prevent death. This article examines pressure ulcer correlates in a representative sample of 15,121 nursing home residents in 1994 in the state of Ohio. The prevalence of pressure ulcers was 12%, 8% for Stage 2 or greater. The study found that many nursing home residents remain at great risk of developing pressure ulcers. Important risk factors included a history of cured pressure ulcers, new admission and readmissions, dependencies in activities of daily living, weight loss and dehydration, diabetes, edema, and incontinence. After controlling for clinical factors, residents in rural facilities were less likely to have a pressure ulcer. These findings suggest that the quality of pressure ulcer care in nursing homes could improve.

Diabetes mellitus is very common in older persons. Changes in exercise habits, body habitus, leptin, amylin, tumor necrosis factor alpha, and nitric oxide all play a role in the pathogenesis of age-related insulin resistance. In older persons elevated glucose levels not only produce retinopathy, neuropathy, and nephropathy but also decrease quality of life, pain tolerance, cognition, and functional status and increase injurious falls, nocturia, incontinence, pressure ulcers, and orthostatic hypotension. The availability of multiple new therapies has enhanced the ability of physicians to improve glycemic control in older persons without unacceptable levels of hypoglycemia. Caregivers play an important role in the management of older diabetics. Depression increases mortality rate and hospital admissions in older diabetics. In many nursing homes the quality of diabetic care is marginal. A new causative theory of the metabolic syndrome involving cytokines and nitric oxide-the NO cytokine theory-is proposed.

During the period from July 1995 to June 1996 we performed transurethral resection of the prostate (TURP) on 824 patients with benign prostatic hyperplasia (BPH). Among them, 13 were dementia patients between 74 and 96 years old; they presented with urinary hesitancy in 6, retention in 4, frequency in 2 and incontinence in 1 patient. Past history included stroke in 7, hypertension in 6, pulmonary tuberculosis in 4, diabetes in 3, asthma in 2, angina pectoris in 1, Parkinson's disease in 1, pneumonia in 1, and hepatitis in 1. Careful preoperative examination revealed that they were proper candidates for TURP. They underwent TURP under spinal anesthesia. The mean operative time was 34 min, ranging from 20 to 60 min. The adenoma resected weighed 24 g on the average, ranging from 7.5 to 48 g. During surgery, although hypotension was noted in 2 patients, there was no serious morbidity. Their mental condition was well controlled with ketamine and diazepam during and after surgery. Postoperative complications included acute myocardial infarction in 1, multiple gastric ulcer in 1, and decubitus in 1. None died within 3 months after TURP, 3 died there after, and 10 patients were alive at the mean follow-up period of 26 months. Six patients reported good urination, 3 reported some improvement in urination after surgery, although requiring intermittent catheterization and 1 developed mild incontinence. In conclusion, TURP appears to provide some benefit in selected patients with dementia and should not be considered to be a contraindication for such patients.

Problems related to the urogenital tract are common in elderly women. Control of micturition is often impeded and questionnaire-based studies have reported a prevalence of poor control of micturition in about 30% of postmenopausal women. In an ongoing cohort comprising women born between 1935 and 1945, an interim analysis was performed in 1800 women based on an interview and questionnaire. The prevalence of urinary incontinence was found to be 33%, which is in accordance with previous reports. The main difference between the interview and the questionnaire was that the interview could take into account intensity as well as intermittence of symptoms. There were no differences between premenopausal women and postmenopausal women using or not using hormone replacement therapy. In agreement with earlier studies, we found poorer control of micturition in parous women. A higher percentage of incontinence was also found in women who had lost more than 5 kg in body weight during the preceding 5 years. In addition, women with a family history of diabetes were more prone to complaints of incontinence. Of the 155 women who had a family history of diabetes, 66 were incontinent (p < 0.01). It was also found that women who were incontinent were more often on regular surveillance for various diseases, using more medications regularly and had been hospitalized during the last 5 years more often than women who were continent. There were no differences in smoking habits. The present results imply that urinary incontinence in women is of a complicated origin and that the hormonal situation plays a minor role for this socially handicapping symptom.

The underlying risk factors, presenting features, and outcome of 22 children with sacral agenesis and associated neuropathic bladder were studied retrospectively. The age of children at presentation was bimodally distributed, with peaks below 1 year and between 4 and 5 years of age. Ten patients presented after 1 year. The oldest was diagnosed at 12 years of age. In 12 children there was maternal diabetes, orthopaedic anomalies in 14, skin defects in 11, and anorectal/tracheooesophageal anomalies in three. Most children had persistent dribbling of urine on presentation associated with frequency, urgency, recurrent urinary tract infections, failure to respond to medication, and/or constipation. Twenty-one children had abnormal neurology in the lower limbs. Videourodynamics showed neuropathic vesicourethral dysfunction in all children and vesicoureteric reflux in 10. Nineteen had a history of urinary tract infections. Seven had renal scarring, with renal impairment in three at presentation. Clean intermittent catheterization was recommended for 20 of the children. Bladder or bowel surgery has been carried out in seven and neurosurgery performed in two. Twenty of the 22 children underwent operative procedures. Ten operations were performed before sacral agenesis was diagnosed. Over a third of the children have required psychological support. The combination of urinary symptomatology and any of the above risk factors should give rise to a high level of suspicion and low threshold to perform investigations to exclude sacral agenesis. All these children have abnormal bladder and urethral function which not only causes incontinence but puts the kidneys at risk. Early detection allows effective multidisciplinary input specifically aimed at continence, preservation of renal function, and adequate psychological support.

Spinal epidural abscess (SEA) was first described in the medical literature in 1761 and represents a severe, generally pyogenic infection of the epidural space requiring emergent neurosurgical intervention to avoid permanent neurologic deficits. Spinal epidural abscess comprises 0.2 to 2 cases per 10,000 hospital admissions. This review intends to offer detailed evaluation and a comprehensive meta-analysis of the international literature on SEA between 1954 and 1997, especially of patients who developed it following anesthetic procedures in the spinal canal. In this period, 915 cases of SEA were published. This review is the most comprehensive literature analysis on SEA to date. Most cases of SEA occur in patients aged 30 to 60 years, but the youngest patient was only 10 days old and the oldest was 87. The ratio of men to women was 1:0.56. The most common risk factor was diabetes mellitus, followed by trauma, intravenous drug abuse, and alcoholism. Epidural anesthesia or analgesia had been performed in 5.5% of the patients with SEA. Skin abscesses and furuncles were the most common source of infection. Of the patients, 71% had back pain as the initial symptom and 66% had fever. The second stage of radicular irritation is followed by the third stage, with beginning neurological deficit including muscle weakness and sphincter incontinence as well as sensory deficits. Paralysis (the fourth stage) affected only 34% of the patients. The average leukocyte count was 15,700/microl (range 1,500-42,000/microl), and the average erythrocyte sedimentation rate was 77 mm in the first hour (range 2-50 mm). Spinal epidural abscess is primarily a bacterial infection, and the gram-positive Staphylococcus aureus is its most common causative agent. This is true also for patients who develop SEA following spinal anesthetics. Magnetic resonance imaging (MRI) displays the greatest diagnostic accuracy and is the method of first choice in the diagnostic process. Myelography, commonly used previously to diagnose SEA, is no longer recommended. Lumbar puncture to determine cerebrospinal fluid protein concentrations is not needed for diagnosis and entails the risk of spreading bacteria into the subarachnoid space with consequent meningitis; therefore, it should not be performed. The therapeutic method of choice is laminectomy combined with antibiotics. Conservative treatment alone is justifiable only for specific indications. Laminotomy is a therapeutic alternative for children. The mortality of SEA dropped from 34% in the period of 1954-1960 to 15% in 1991-1997. At the beginning of the twentieth century, almost all patients with SEA died. Parallel to improvements in the mortality rate, today more patients experience complete recovery from SEA. The prognosis of patients who develop SEA following epidural anesthesia or analgesia is not better than that of patients with noniatrogenic SEA, and the mortality rate is also comparable. The essential problem of SEA lies in the necessity of early diagnosis, because only timely treatment is able to avoid or reduce permanent neurologic deficits. The problem with spinal epidural abscesses is not treatment, but early diagnosis - before massive neurological symptoms occur" (Strohecker and Grobovschek 1986).

Despite improvements in the supportive care of immunosuppressed patients controversy still surrounds the surgical management and outcome of anorectal sepsis in these patients. We reviewed 83 immunocompromised patients with diagnosis of perianal sepsis from 1995 to 1997. Sixty-six patients (80%) were followed for a mean of 15 months. Mean age was 44 years and 76 per cent were males. Twenty-eight per cent were HIV+, 34 per cent had inflammatory bowel disease on steroids, 20 per cent had malignancies, and 18 per cent had diabetes. Twenty-eight per cent had anal fistula, 2 per cent had perianal abscess, and 40 per cent had both. Primary sites of fistula were: transsphincteric (38%), intersphincteric (33%), superficial (20%), and suprasphincteric (3%), and multiple tracks (6%). Horseshoeing was present in 14 per cent of cases. The most commonly practiced surgical procedures were primary fistulotomy (n = 23) and fistulotomy plus drainage (n = 28). Seven patients underwent fistulotomy and ostomy and eight patients were treated with fistulectomy plus drainage. Most wounds (91%) healed within 8 weeks. Incontinence (6%) and recurrence (7%) were the most commonly observed complications. These results are similar to those seen in the general population. Perianal sepsis can be safely managed in immunocompromised patients, with high rates of healing and low complication rates. An aggressive sphincter-preserving approach in the management of these patients may be undertaken.

The aim of this case-control study was to identify etiologic factors predictive for the development of severe pelvic organ prolapse. Three hundred and sixty-eight controls from a database describing pelvic organ support in the general population were identified as having known good pelvic organ support. Eighty-seven cases were identified from a urogynecology clinic with severe pelvic organ prolapse. The risk of severe prolapse was modeled using stepwise multiple logistic regression analysis. Additional analyses using chi2 and two-sample t-tests were conducted to determine differences in means for individual variables. Variables examined included age, gravidity, parity, number of vaginal deliveries, weight of largest infant delivered vaginally, menopause status, race, body mass index prior to pelvic surgery, and medical illnesses. The following four variables were selected in the regression analysis as predicting severe prolapse: age, weight of largest vaginal delivery, hysterectomy and previous prolapse surgery. Other variables that demonstrated statistically significant differences between groups by chi2 and two-sample t-tests were gravidity, parity, number of vaginal deliveries, menopausal status, race, history of incontinence surgery and the presence of hypertension. Variables that did not demonstrate any significant differences were body mass index, the presence of chronic obstructive pulmonous disease and diabetes mellitus. Advancing age, increasing weight of infants delivered vaginally, a history of hysterectomy and a history of previous prolapse surgery were found to be the strongest etiologic predictors of severe pelvic organ prolapse in our population.

Metformin is an effective and commonly administered drug for controlling plasma glucose concentrations in patients with type 2 diabetes mellitus. Gastrointestinal adverse effects such as abdominal pain, nausea, dyspepsia, anorexia, and diarrhea are common and widely accepted when occurring at the start of metformin therapy. Diarrhea occurring long after the dosage titration period is much less well recognized. Our patient began to experience nausea, abdominal cramping, and explosive watery diarrhea that occasionally caused incontinence after several years of stable metformin therapy A trial of metformin discontinuation resolved all gastrointestinal symptoms. A review of the literature revealed two reports that suggest diarrhea occurring long after the start of metformin therapy is relatively common, based on surveys of patients with diabetes. Metformin-induced diarrhea is differentiated from diabetic diarrhea, which is clinically similar, except diabetic diarrhea is rare in patients with type 2 diabetes. Patients with type 2 diabetes who are taking metformin and experience diarrhea deserve a drug-free interval before undergoing expensive and uncomfortable diagnostic tests, even when the dosage has been stable over a long period.
