Objective To investigate the relationship between heart rate variability (HRV) and prostaglandin E2 (PGE2) in patients with renal insufficiencies.Methods HRV blood and 24-hour urine prostagladin E2 (PGE2) detection were detected in the following 4 groups of people: group A was a control group comprised of 20 normal individuals; group B had 20 patients with renal disease but exhibiting normal renal function; group C contained 20 patients with renal disease and compensatory renal function; group D had 20 patients demonstrating renal insufficiencies. The indices standard deviation of all NN intervals (SDNN), index of standard deviation of the averages of NN intervals (SDANN), mean of the standard deviation of all NN intervals performed on all 5-minute segments of the entire recording (SDNNindex), square root of the mean of the sum of the squares of differences between adjacent NN intervals (rMSSD) and NN50 count divided by the total number of all NN intervals (PNN50) were used to evaluate HRV, blood and 24 相似文献

Moderate (greater than 20 units) and high (greater than 80 units) IgG anticardiolipin antibody (aCL) titres are strongly predictive for recurrent thrombosis and early myocardial infarction in non-diabetic subjects. We have tested the hypothesis that the excess risk of myocardial infarction in diabetic subjects relates to the presence of aCL by measuring the frequency and titre of aCL in two groups of diabetic subjects and in 2500 healthy controls. One non-diabetic subject (0.04%) had low (5-20 units) IgG aCL titres. Seven out of 126 diabetics without cardiovascular disease (5.6%) and 9 out of 79 diabetics who were either myocardial infarction survivors or who had angiographically-proven coronary artery disease (11.4%) had low aCL titres (P less than 0.01 for comparison of either diabetic group with controls, and P less than 0.1 for comparison between diabetic groups). One subject in each diabetic group, but no non-diabetics, had moderate IgM aCL titres. No subjects had high aCL titres. Diabetics have an increased frequency of low aCL titres which may relate to macrovascular disease. Macrovascular disease in diabetics is not associated with moderate or high aCL titres. 相似文献

In a clinic population of 509 type 1 diabetic patients aged 16-45 years, 5.5% had received treatment for thyroid disorders (20 hypothyroid, three males; eight thyrotoxicosis, four males), and Addison's disease was present in four patients (0.8%, one male). In all patients, type 1 diabetes preceded the diagnosis of the other autoimmune disorder. The clinical presentation of hypothyroidism was usually insidious with few symptoms, although an increased frequency of hypoglycaemic symptoms and/or raised serum cholesterol levels often prompted thyroid function testing. In contrast, the patients with thyrotoxicosis had florid symptoms, weight loss (mean 8.12 kg), palpable goitres, increasing insulin requirements, and low cholesterol levels. Six patients did not achieve remission or had recurrent thyrotoxicosis after oral antithyroid treatment and required 131I or thyroid surgery. A family history of autoimmune disease was present in 25% of patients with thyroid disorders (seven thyrotoxic and one hypothyroid) and in three of the four patients with Addison's disease. In this population of young adult type 1 diabetic patients, appropriate tests for thyroid dysfunction and Addison's disease should be carried out if there is clinical suspicion and/or unexplained changes in diabetic metabolic control or serum cholesterol. Careful follow-up of patients with a family history of these conditions is recommended. 相似文献

Nineteen patients with Cushing's disease were treated with low dose external pituitary irradiation (20 Gy (2000 rad) in eight fractions over 10 days). While awaiting the effects of pituitary irradiation all patients were treated with metyrapone. Seven patients had a complete remission of their disease within six to 12 months of irradiation. They did not require any further treatment and were followed up for a mean of three and a half (range one to eight) years. Another patient had a complete remission after a second course of pituitary irradiation. A further two patients showed a significant biochemical improvement after irradiation, although they were not rendered eucorticoid. There were no complications after this dose of irradiation. These results compare favourably with those reported after pituitary irradiation at conventional doses (40-50 Gy (4000-5000 rad) over four or five weeks) but were not associated with any complications. It is therefore recommended that low dose external pituitary irradiation be used as definitive first line treatment for Cushing's disease. 相似文献

OBJECTIVE--Determining the microbial cause of cellulitis is often difficult. In this study, a novel two-needle lavage technique was used to culture Borrelia burgdorferi from the skin of suspected erythema migrans lesions. DESIGN--The yield of lavage cultures for B burgdorferi was compared with that of a 2-mm skin biopsy sample. SETTING--A Lyme disease diagnostic center located in an area in which Lyme disease is epidemic. PATIENTS--Forty-five patients with suspected erythema migrans who had not been treated with antimicrobial agents. INTERVENTION--Cutaneous lavage of the advancing edge of a suspected primary erythema migrans lesion was done for all 45 participants, 33 of whom also had a skin biopsy of the same lesion at an identical (14) or an adjacent (19) site. MAIN OUTCOME MEASURES--Growth of B burgdorferi in in vitro culture. RESULTS--Lavage fluid cultures grew B burgdorferi in 13 (29%) of the 45 cases (95% confidence interval [CI], 16% to 44%). Among the 33 cases in which both lavage and skin biopsy cultures were done, the yield of lavage culture was less than that of biopsy culture (P less than .09, 12/33 vs 20/33). If contaminated cultures are excluded, this difference is significant (P less than .05, 12/30 vs 20/27). CONCLUSION--Cutaneous lavage is a new diagnostic technique for recovery of B burgdorferi from erythema migrans lesions that has potential applicability to other types of cutaneous infections. 相似文献

Seventy one patients with alcoholic liver disease and an equal number with non-alcoholic liver disease were interviewed using the schedule for affective disorders and schizophrenia. Forty seven (66%) of the group with alcoholic liver disease had or had had psychiatric illnesses compared with 23 (32%) of the control group (p less than 0.001). Affective disorder, particularly major depression, neurotic disorders, and antisocial personality, were all more common among the patients with alcoholic liver disease than the controls. No patient had schizophrenia or other forms of psychosis. Among the patients with alcoholic liver disease 11 men (24%) and 14 women (54%) had an affective or a neurotic disorder that had antedated their heavy drinking, and 30 (77%) of those who had had such a problem at any time had symptoms at the time of interview. Abstinence from alcohol is essential for patients with severe alcoholic liver disease. In view of the high prevalence of psychiatric disorders in these patients psychiatric assessment is important to increase the patients' likelihood of complying with such advice. 相似文献

A survey of UK patients receiving the drug diazoxide, revealed 40 patients with insulinoma on this treatment. Mean age (+/- SD) was 67 +/- 18 years, and 74% were female. Duration of treatment was 7 +/- 6 years (range 1-22). Most (55%) patients were treated with diazoxide because of tumour non-localisation (including failed previous surgery). Metastatic disease (20%) and poor surgical risk (10%) were other indications. Side-effects (notably fluid retention and hirsutism) were common (47%) but not troublesome. Treatment was highly effective--59% were symptom free and 38% had only occasional symptoms. Only one patient had frequent hypoglycaemia despite treatment. We conclude that diazoxide is effective in the management of insulinoma. Side-effects are common but not problematic. Treatment should be considered for all patients not cured by surgery, or unsuitable for surgical treatment. 相似文献

Mortality from coronary heart disease has declined by approximately 50% in Australia over the past 20 years and now accounts for approximately 25% of all deaths. Most of the decline in mortality from all causes in each State of Australia over the period 1972-1988 is due to the decline in mortality from coronary heart disease. In Tasmania, the rate of decline in mortality from all causes is significantly less in both sexes (P less than 0.01) than in the mainland States, and the discrepancy is due to a lesser decline in mortality from coronary heart disease (P less than 0.01). Trends in deaths related to hypertension show no differences between Tasmania and the other States, which suggests that the discrepancy with coronary heart disease is due to factors other than the prevalence and/or treatment of hypertension. Analysis of trends data on cigarette smoking prevalence, and cross-sectional data on plasma cholesterol levels and diet, shows that Tasmanian differences in food intake (including fat and cholesterol), in plasma cholesterol levels and (to a lesser extent) in cigarette smoking are consistent with, but are unlikely to explain completely, the slower rate of decline in mortality from coronary heart disease. 相似文献

The aim of this retrospective study is to assess the value of routine ultrasonography in the detection of renal abnormalities.
Twenty-nine pregnancies (one set of twins) with suspected renal abnormalities (i.e. renal cystic spaces, oligohydramnios or
hyperechoic kidneys) were delivered over a two year /period (1.8.1987-31-7-1989) in a unit where 90% of pregnancies (6,562)
were scanned routinely at 18–20 weeks gestation or later, if booking for confinement was delayed. In pregnancies with suspected
anomalies prenatal ultrasound was performed monthly until 28 weeks and fortnightly until delivery. Non survivors [5] had histological
or postmortem examination. Liveborn infants [25] had renal ultrasonography in the neonatal period and paediatric follow-up
if abnormal. Sixteen (53%) of the 30 cases (one set of twins) suspected of renal abnormalities by routine prenatal ultrasonography
had renal anomalies confirmed postnatally. Five women were non survivors, all of which had associated anomalies. In the eleven
survivors the diagnoses were pelviureteric junction obstruction [6], renal dysplasia [2], vesicoureteric reflux [2] and suspected
ureterocoele [1]. Fourteen infants with pelvicalyceal dilatation had normal postnatal renal ultrasound.
Although abnormal prenatal renal ultrasound is a useful indicator of postnatal disease and aids decisions on the management
of pregnancy, further large collaborative studies with extended paediatric follow-up are required to assess the significance
of pelvicalyceal dilatation. 相似文献

Serial concomitant paired sera (S) and CSF were taken from eight patients with biopsy-proved herpes simplex virus encephalitis (HSVE). These specimen pairs were compared with 28 others from patients with various neurologic conditions. Before and after reduction with 2-mercaptoethanol, a ratio of S/CSF antibody titers of less than or equal to 20 with either the passive hemagglutinating (PHA) or immune adherence hemagglutinating (IAHA) antibody tests occurred in every patient with HSVE. Diagnostic S/CSF ratios were noted in three patients before biopsy of the brain and in four patients by the tenth day of neurologic disease. Among control subjects, a ratio of S/CSF titers greater than 20 was observed in all but four patients. Each of the latter patients had neurologic diagnoses easily distinguishable from HSVE. The PHA or IAHA S/CSF ratio offers a rapid, reliable method for the diagnosis of HSVE (P less than .001). 相似文献

The Medical Association of Georgia's Impaired Physicians Program. Review of the first 1000 physicians: analysis of specialty 总被引:5,自引:0,他引:5
Risk factors for the disease of chemical dependence, or addiction to alcohol and/or drugs, for physicians have not been clearly defined. Yet chemical dependence is believed to be a leading occupational hazard for physicians. This study compares the specialties of a population of physicians assessed for the presence of impairment (study group, N = 1000) with the distribution of specialties for all US physicians. Only 21 of the total were found to be free of impairment from chemical dependence or psychiatric disease, while 920 physicians (92.0%) had a primary diagnosis of chemical dependence, and 59 (5.9%) had a major psychiatric illness. Anesthesia and family and general practice were found to be overrepresented in the population under study, as compared with all US physicians. There were significant differences between the study group and all US physicians with respect to age, sex, and practice activity status. The authors urge these apparent high-risk specialties, as well as the medical profession itself, to develop control or prevention strategies that will reduce risk for chemical dependence through education, early identification, intervention, and treatment of those individuals with the disease. 相似文献

Forty-one patients with Langerhans Cell Histiocytosis (LCH) were treated over a thirty-one year period in our institution. These children were classified according to the number of systems involved: twenty-two had unisystem disease while nineteen had multisystem disease. A histological diagnosis was reached in 82 % of cases, the remainder being diagnosed on both radiological and clinical grounds. 68 % of those with multisystem disease had a rash at diagnosis whilst 64% had a persistent ear discharge. The diagnosis was established accidentally in 25% of those with unisystem disease. The mortality rate was 21 % and was confined to those who were under two years of age at diagnosis, all of whom had multisystem disease. Morbidity was 20% and was restricted to patients with multisystem disease. Only one patient died within the last 10 years; there were no therapy related deaths. Treatment related morbidity was seen in only three children. In keeping with other series, our review has identified the following adverse prognostic factors a) age under 2 years at presentation, b) multisystem disease and c) major organ dysfunction. In view of the natural history of the disease, it is suggested that chemotherapy only be used in those patients who have major organ dysfunction or progressive disease and that radiotherapy is rarely indicated. 相似文献

THE faecal flora of patients with Crohn’s disease differs from that of healthy subjects in that it contains higher concentrations of anaerobic Gram-negative rods and Gram-positive coccoid rods of the genera Peptostreptococcus, Eubacterium and Coprococcus. As part of an international study of agglutinins to these bacteria we submitted sera from 20 patients with Crohn’s disease, 19 with ulcerative colitis and 20 control subjects. These sera were tested in Rotterdam by personnel who had no prior knowledge of the diagnosis and were scored positive or negative for Crohn’s disease according to the strength of agglutination. In patients with Crohn’s disease the sera was strongly positive in 65% of cases. The test was positive in 26% of patients with ulcerative colitis, while all the control sera were negative for agglutinins. Our data compared favourably with that of the international survey. On the basis of these results the agglutinin test is put forward as a useful aid in discriminating between the two principal inflammatory bowel diseases and the significance and limitations of the test are discussed. 相似文献

In the past 5 1/2 years, 71 patients with diverticulitis were operated on--20.8% of all cases of diverticulitis admitted to the Bronx Municipal Hospital Center. Operative mortality was 22%, primarily because of delayed diagnosis, inadequate surgery, and a high incidence of associated disease. Only 20% of patients operated on had a previous history of diverticular disease. Hemorrhage was the indication for surgery in 16 cases; in this situation, a subtotal colectomy in one stage is the operation of choice. Perforation was the indication in 47 cases, eight of these being acute and with free air under the diaphragm. In cases with peritoneal contamination, a two-stage procedure (removing the diseased portion of colon at stage one) is advocated. Colostomy without drainage, or closure of a free perforation, is condemned. 相似文献
