An 18 year old girl with typical clinical features of Williams syndrome suddenly died of intracerebral hemorrhage due to moyamoya disease. Autopsy revealed vascular abnormalities, such as supravalvular aortic stenosis (SAS) and an abnormal complicated cerebrovascular network in the cerebral arteries. The arterial wall of the SAS lesion consisted of thickened medial tissue showing elastic disorganization with prominence of the smooth muscle cells. The narrowed vessels of the circle of Willis showed intimal thickening with an extremely wavy internal elastic lamina and marked thinning of the media. To our knowledge, this is the first report of moyamoya disease associated with Williams syndrome. 相似文献

We examined sera from 10 patients with hemolytic uremic syndrome (HUS) and 51 controls, with and without diarrhea, for antibodies to Escherichia coli lipopolysaccharides (LPS) O157, O111 and O26 using the indirect hemagglutination (IHA) assay. A significant rise (to a titer of ≥ 2560) in IHA antibody to O157 LPS was detected in eight of the 10 HUS patients, to O111 in two patients, one of whom showed concomitantly an antibody rise to O157, but to O26 in no patients. The IHA titers fell rapidly after the acute phase of the illness. Of the control sera 15 (29.4%) non-specifically agglutinated uncoated sheep red blood cells (SRBC) at a titer of ≥80, six (3.9%) at ≥320 and the maximum was 640. In spite of the relatively low level of non-specific agglutination the IHA appeared to be a useful screening method to identify verotoxin-producing E. coli infections at the early stage of HUS because the titers were clearly higher than non-specific agglutination and the assay is easy to perform and gives results quickly. Artificial carriers are being considered for use in place of SRBC to diminish the non-specific hemagglutination. 相似文献

Background: Acute inferior myocardial infarction (MI) often induces transient sinus bradycardia through vagal enhancement, known as Bezold-Jarisch reflex, which is explained by preferential distribution of vagal nerve in the inferior wall. We examined vagal activity in relation to the occurrence of residual ischemia in patients with old inferior MI and assessed its diagnostic usefulness.
Methods: Exercise myocardial scintigraphy was performed in 15 patients with old inferior MI, 19 angina pectoris (AP) patients with inferior ischemia but no MI, and 32 control subjects who had no evidence of cardiac disease. We analyzed the connection of residual ischemia in old MI with ST-segment response to exercise and with vagal activity as determined by coefficient of component variance of high frequency (CCVHF ).
Results: Exercise-induced percentage change in CCVHF was higher in patients with old MI and residual ischemia (18.8 ± 13.5%) and AP (5.5 ± 9.7%) than old MI but no residual ischemia (–24.1 ± 4.9%) or control (–22.8 ± 4.5%, P = 0.006). Percentage change in CCVHF > –5% had a good diagnostic value for the detection of residual ischemia in patients with old inferior MI with sensitivity of 83%, specificity of 89%, accuracy of 87%, and positive likelihood ratio of 7.50, which was higher than that of ST-segment depression (67%, 50%, 56%, and 1.33).
Conclusions: Vagal enhancement was associated with residual ischemia in old inferior MI as well as inferior AP. Measurement of CCVHF is useful in improving the diagnostic reliability of exercise electrocardiography in patients with old inferior MI. 相似文献

Alcohol dementia and alcohol delirium in aged alcoholics 总被引:1,自引:0,他引:1
HIROO KASAHARA MD AKIHIDE KARASAWA MD TAKAYOSHI ARIYASU MD TATSUYA THUKAHARA MD JOUJI SATOU MD SADANOBU USHIJIMA MD 《Psychiatry and clinical neurosciences》1996,50(3):115-124
Abstract In the present study, 126 alcoholics aged 60 years or older were compared with 104 alcoholics aged 35–45 years. No dementia was found in the younger group, whereas 62.7% of the aged patients had dementia; the dementia being irreversible in 32.9% of such patients. Cases of so-called alcohol dementia excluding organic brain diseases accounted for 42.1%. The percentage of aged alcoholics having dementia increased with age, being far beyond the frequency of senile dementia in the general aged. Among various physical complications, hepatic injury and myocardiopathy were more frequent in the aged alcoholics than in general aged people, suggesting that hypertension, myocardiopathy and hepatic injury underlie the manifestation of dementia. There was no case of dementia attributable to the direct effect of alcohol distinctly exceeding the effects of various physical factors. Problem behaviors characteristic of the aged group included 'being soaked in drink' and being inebriated, showing no correlation with the presence or absence of dementia. There was no significant difference in frequency of delirium between the aged group and the younger group. However, in aged alcoholics delirium tended to continue for a longer period during abstinence and was more likely to occur even during non-abstinence. A similar trend was found in aged alcoholics with dementia compared with those without dementia. 相似文献

BACKGROUND: Cryoablation is a treatment option for some patients with small exophytic lesions of the kidney. The purpose of this study is to determine the feasibility, safety, and intermediate-term treatment outcome of percutaneous cryoablation of renal cell carcinoma guided by horizontal open magnetic resonance imaging (MRI). METHODS: We prospectively used cryoablation to treat 13 patients with radiographically confirmed enhancing small, solid renal tumors (< or =4.8 cm). An argon gas-based cryoablation system was used. One to four cryoprobes with 2 or 3-mm diameters were placed percutaneously into the tumor under local anaesthesia and MRI guidance. Ice ball dimensions were monitored by 2-D MR images. Double freeze-thaw cycles were conducted throughout the procedure. After successful cryoablation, patients were followed on a regular basis to evaluate the treatment's clinical outcome. RESULTS: Median follow up from time of procedure is 35 months (range, 28-42). In all cases the entire procedure was accomplished without significant morbidity or complications. A mild retroperitoneal hematoma, which subsided spontaneously, was noted in one patient. Follow-up dynamic computed tomography (CT) at 3 months after operation confirmed the absence of enhancement in resolved tumor masses for 11 of 13 cases. None of these 11 patients had clinical evidence of recurrent disease at last follow up. The remaining two patients had lesions with some enhanced areas. Subsequent partial nephrectomy histologically confirmed the presence of vital tumor in, respectively, the center and the periphery of the residual masses. One of these patients developed multiple lung and ipsilateral adrenal metastases 13 months after surgical resection. CONCLUSIONS: Percutaneous cryoablation of small renal cell carcinomas under horizontal open MRI guidance appears to be safe and feasible. An intermediate-term follow up continues to demonstrate efficacy in most patients; however, a few patients experience incomplete ablation with risk of treatment failure. The ideal candidates for this procedure still need to be determined in longer follow up with diligent observation. 相似文献

The loss of haemolytic activity in sera during storage at low temperature (the cold activation of complement) was observed in 136 of 184 (74%) patients with chronic liver disease associated with hepatitis C virus (HCV) infection. This was more frequent than observed in the three of 40 (8%) patients with chronic hepatitis B (P < 0.001) or none in 43 normal controls (P < 0.001). Of 103 patients with chronic hepatitis C who had completed a full course of recombinant interferon-α2a therapy (total dose: 516×106U), 40 responded completely and 21 responded partially, as judged by the normalization or decrease of alanine aminotransferase levels 6 months after the completion of therapy; 42 patients did not respond at all. The cold activation of complement persisted in five (13%) complete responders, less often than in 33 (79%) non-responders (P < 0.001). At the completion of interferon therapy, the cold activation of complement persisted in 12 of 54 patients despite the normalization of alanine aminotransferase. Spontaneous exacerbation of hepatitis occurred in seven of 12 (58%) patients with cold activation, which was more frequent than in the four of 42 patients (10%) without it (P < 0.01). The cold activation of complement disappeared along with the loss of HCV-RNA in five of six responders during the 6 month period after the completion of interferon therapy, while both cold activation and HCV-RNA persisted in all eight non-responders. These results indicate that the cold activation of complement may be useful as a marker of HCV viraemia for monitoring the response to interferon in patients with HCV infection. 相似文献
