200 years have gone by since the autonomic disturbance in diabetes mellitus has been described for the first time ever. There is a great deal of information on the close relationship between somatic and visceral symptoms in diabetic polyneuropathy (PNP), so that there should be talked about only of one form of manifestations within the meaning of a distal symmetric somatovisceral PNP. The longer fibres such as the vagal fibres of the viscus, sympathetic fibres of the eye are affected at first and more intensively in the autonomic region same as in the sensory and motor region. Due to the fact that for reasons of fragmentary knowledge pathogenetically substantiated classification of the autonomic disturbances in diabetic PNP is not at hand, such a classification is being made from organotopic and phenomenologic aspects. Frequently, afferent denervation of an organ results in enhancing the effects of an autonomic innervation dysfunction, as for instance in unnoticed hypoglycaemia, in order to modify the symptoms, as for instance in rectal incontinence with unnoticed defecation, or rather to let new symptoms appear, for instance loss of testicular pain. In recent years, appropriate methods of examinations were tested for the clinical routine, permitting to give evidence of autonomic dysfunctions before clinical manifestation. It is still unclear to what extent such subclinical abnormalities are reversible with a more favourable regulation of the metabolic process, for instance with the aid of continuous subcutaneous insulin injections. An impressive symptom of innervation dysfunctions of the cardiovascular system is orthostatic hypertension that may, in exceptional cases, even lead to confinement to bed. The most important pathogenic factor seems to be vascular denervation. A pronounced tachycardia at rest, frequently found in diabetics, is the result of the failure of the vagal autonomic system, and, after additional destruction of the sympathetic fibres, it adjusts itself to a lower level that cannot be changed by reflex mechanisms. Cardialgia absent in the case of myocardial ischemia is a factor of an increased mortality of long-term diabetics. The correlation between vascular denervation and arteriosclerosis or mediasclerosis, respectively, is being under discussion. Denervation on the gastrointestinal tract has an effect on the motility and excretory functions. The innvervation dysfunctions lead to sialadenosis by changing the composition of saliva. In most cases esophageal dysfunction is not perceived by the patient.(ABSTRACT TRUNCATED AT 400 WORDS)

Many patients find polyethylene glycol-based preparations (PEG) difficult to take because of the large volume of fluid they are required to consume. One hundred and sixteen predominantly elderly patients were randomized to receive either sodium phosphate (n = 61) or PEG (n = 55) bowel preparations before colonoscopy. Patients with a history of symptomatic ischaemic heart disease or cerebrovascular disease in the preceding 6 months, severe liver disease or heart failure, or serum creatinine above 200 micrograms/L were excluded from the study. Each patient filled in a questionnaire about the bowel preparation prior to the procedure. The colonoscopists, who were not aware which preparation had been used, were asked to complete a questionnaire about the quality of the bowel preparation after the procedure. The patients found the sodium phosphate preparation slightly more tolerable than PEG. Side effects were slightly more common with sodium phosphate. Neither difference was statistically significant. However, 91% of patients who had previously had PEG found sodium phosphate easier to take. Approximately 25% of patients in each group experienced at least one episode of incontinence. The colonoscopists found no difference in the overall quality of the bowel preparation. The amount of fluid in the colon was greater in patients prepared with PEG. As expected, patients taking sodium phosphate developed hyperphosphataemia (mean phosphate level before colonoscopy 1.56 mmol/L, normal 0.8 -1.3). They also had a lower mean serum potassium level (3.8 mmol/L) than the PEG group (4.2 mmol/L). However, there were no clinically significant consequences. Sodium phosphate was a safe and effective bowel preparation for colonoscopy in this carefully selected group of patients. It was preferred by patients who had previously had PEG. Many elderly patients were found to develop faecal incontinence, irrespective of the type of bowel preparation used.

Diabetic autonomic neuropathy (DAN) is a serious and common complication of diabetes. Despite its relationship to an increased risk of cardiovascular mortality and its association with multiple symptoms and impairments, the significance of DAN has not been fully appreciated. The reported prevalence of DAN varies widely depending on the cohort studied and the methods of assessment. In randomly selected cohorts of asymptomatic individuals with diabetes, approximately 20% had abnormal cardiovascular autonomic function. DAN frequently coexists with other peripheral neuropathies and other diabetic complications, but DAN may be isolated, frequently preceding the detection of other complications. Major clinical manifestations of DAN include resting tachycardia, exercise intolerance, orthostatic hypotension, constipation, gastroparesis, erectile dysfunction, sudomotor dysfunction, impaired neurovascular function, "brittle diabetes," and hypoglycemic autonomic failure. DAN may affect many organ systems throughout the body (e.g., gastrointestinal [GI], genitourinary, and cardiovascular). GI disturbances (e.g., esophageal enteropathy, gastroparesis, constipation, diarrhea, and fecal incontinence) are common, and any section of the GI tract may be affected. Gastroparesis should be suspected in individuals with erratic glucose control. Upper-GI symptoms should lead to consideration of all possible causes, including autonomic dysfunction. Whereas a radiographic gastric emptying study can definitively establish the diagnosis of gastroparesis, a reasonable approach is to exclude autonomic dysfunction and other known causes of these upper-GI symptoms. Constipation is the most common lower-GI symptom but can alternate with episodes of diarrhea. Diagnostic approaches should rule out autonomic dysfunction and the well-known causes such as neoplasia. Occasionally, anorectal manometry and other specialized tests typically performed by the gastroenterologist may be helpful. DAN is also associated with genitourinary tract disturbances including bladder and/or sexual dysfunction. Evaluation of bladder dysfunction should be performed for individuals with diabetes who have recurrent urinary tract infections, pyelonephritis, incontinence, or a palpable bladder. Specialized assessment of bladder dysfunction will typically be performed by a urologist. In men, DAN may cause loss of penile erection and/or retrograde ejaculation. A complete workup for erectile dysfunction in men should include history (medical and sexual); psychological evaluation; hormone levels; measurement of nocturnal penile tumescence; tests to assess penile, pelvic, and spinal nerve function; cardiovascular autonomic function tests; and measurement of penile and brachial blood pressure. Neurovascular dysfunction resulting from DAN contributes to a wide spectrum of clinical disorders including erectile dysfunction, loss of skin integrity, and abnormal vascular reflexes. Disruption of microvascular skin blood flow and sudomotor function may be among the earliest manifestations of DAN and lead to dry skin, loss of sweating, and the development of fissures and cracks that allow microorganisms to enter. These changes ultimately contribute to the development of ulcers, gangrene, and limb loss. Various aspects of neurovascular function can be evaluated with specialized tests, but generally these have not been well standardized and have limited clinical utility. Cardiovascular autonomic neuropathy (CAN) is the most studied and clinically important form of DAN. Meta-analyses of published data demonstrate that reduced cardiovascular autonomic function as measured by heart rate variability (HRV) is strongly (i.e., relative risk is doubled) associated with an increased risk of silent myocardial ischemia and mortality. The determination of the presence of CAN is usually based on a battery of autonomic function tests rather than just on one test. Proceedings from a consensus conference in 1992 recommended that three tests (R-R variation, Valsalva maneuver, and postural blood pressure testing)or longitudinal testing of the cardiovascular autonomic system. Other forms of autonomic neuropathy can be evaluated with specialized tests, but these are less standardized and less available than commonly used tests of cardiovascular autonomic function, which quantify loss of HRV. Interpretability of serial HRV testing requires accurate, precise, and reproducible procedures that use established physiological maneuvers. The battery of three recommended tests for assessing CAN is readily performed in the average clinic, hospital, or diagnostic center with the use of available technology. Measurement of HRV at the time of diagnosis of type 2 diabetes and within 5 years after diagnosis of type 1 diabetes (unless an individual has symptoms suggestive of autonomic dysfunction earlier) serves to establish a baseline, with which 1-year interval tests can be compared. Regular HRV testing provides early detection and thereby promotes timely diagnostic and therapeutic interventions. HRV testing may also facilitate differential diagnosis and the attribution of symptoms (e.g., erectile dysfunction, dyspepsia, and dizziness) to autonomic dysfunction. Finally, knowledge of early autonomic dysfunction can encourage patient and physician to improve metabolic control and to use therapies such as ACE inhibitors and beta-blockers, proven to be effective for patients with CAN.

Although the expected mean age of women increased significantly in the 20th century, the time of menopause has not changed (age of 50-51 years). Women's life span in Hungary is 77.2 years, which means, that one third of their lives is lived in menopause. Aging and the consequent lack of estrogen means a more and more serious problem on social level as well. In Hungary there are approximately 1.8 million women above the age of 50. Only an insignificant part of them is treated, which is about 5%, compared to other European countries, where this ratio is between 5 and 25%. Menopause-related symptoms can be divided into the following groups: vasomotor symptoms (sweating, hot flashes, palpitation), decreased psychic and physical functions (fatigue, depression, panic disease, cognitive problems, decreased libido), cardiovascular diseases (ischaemic heart disease), endometrial atrophy, bone and articular alterations (osteoporosis) and urogenital symptoms (vaginal dryness, incontinence, cystitis). The most frequent symptom is hot flashes, which is characteristic of more than 60% of women in menopause. Osteoporosis after the cardiovascular diseases is the second most serious problem on public health level. Approximately 9% of the Hungarian population suffers from osteoporotic problems, which concretely means 600.000 women and 300.000 men. The most frequent fractures are the hip and vertebral fractures. In 1999, 15.100 hip and 51.000 peripheric fractures occurred in Hungary. The above mentioned symptoms, even separately, may decrease the quality of life, therefore their treatment and the knowledge of all of the therapeutic possibilities are essential.

Congenital coronary anomalies are uncommon and are usually diagnosed incidentally during coronary angiogram or autopsy. Isolated coronary artery anomalies and the anomalous origin of left main stem (LMS) from the proximal portion of the right coronary artery or from the right sinus of valsalva are extremely rare. A 68 years old woman with atypical chest pains was referred for risk assessment for the general anaesthesia. A stress exercise treadmill test and myocardial perfusion scan revealed evidence of mild myocardial ischemia. Her coronary angiography revealed her left coronary artery to have a single origin with the right coronary artery. There were no flowlimiting lesions. A CT aortography confirmed a retro-aortic course of the left coronary artery. She successfully underwent multiple surgical procedures under general anaesthesia including total abdominal hysterectomy, Burch colposuspension (twice) for stress incontinence, intravesical botox injection for urge incontinence and haemorrhoidectomy for recurrent rectal mucosal prolapse. Various anaesthetic agents including halothane, thiopentone, suxamethonium, pancuronium, enflurane, fentanyl, propofol and isoflurane were used without any adverse clinical consequences. She remained well on 48 months follow-up.

Objective Macrovascular diseases and urgency incontinence are common among Japanese patients with type 2 diabetes mellitus. However, little evidence exists regarding the association between stroke and urgency incontinence among patients with type 2 diabetes mellitus. We examined the associations between macrovascular complications and urgency incontinence among Japanese patients with type 2 diabetes mellitus. Methods The study subjects were 818 Japanese patients with type 2 diabetes mellitus. Urgency incontinence was defined as present when a subject answered "once a week or more" to the question: "Within one week, how often do you leak urine because you cannot defer the sudden desire to urinate?" We adjusted our analyses for sex, age, body mass index, duration of type 2 diabetes, current smoking, current drinking, hypertension, dyslipidemia, glycated hemoglobin, diabetic nephropathy, diabetic retinopathy, and diabetic peripheral neuropathy. Results The prevalence of urgency incontinence was 9.2%. Stroke was independently positively associated with urgency incontinence, with an adjusted odds ratio of 2.34 (95% confidence interval: 1.03-4.95). The associations between ischemic heart disease or peripheral artery disease and the prevalence of urgency incontinence were not significant. Conclusion In Japanese patients with type 2 diabetes mellitus, stroke, but not ischemic heart diseases or peripheral artery disease, was independently positively associated with urgency incontinence.
