Subacute sclerosing panencephalitis (SSPE) is a rare, slowly progressing but invariably fatal disease that is related to a prior measles virus infection and most commonly affects paediatric patients. Magnetic resonance (MR) imaging is the modality of choice for determining such changes in white matter. SSPE typically demonstrates bilateral but asymmetric periventricular and subcortical white matter involvement. We herein report a rare case of unilateral white matter involvement in a 13-year-old boy with SSPE that closely simulated Rasmussen’s encephalitis. To the best of our knowledge, this is the first report of an atypical presentation on MR imaging in which SSPE was a rare cause of unilateral brain parenchymal involvement in a patient with intractable seizures. 相似文献

Background: Complete resection of a retroperitoneal sarcoma often requires removal of adjacent organs. In this study we evaluated the
role of nephrectomy during operation for retroperitoneal sarcoma.
Methods: Between July 1982 and July 1995, 75 of the 371 (20%) patients who underwent resection of retroperitoneal sarcoma at MSKCC
underwent concommitant nephrectomy. Data concerning the reasons for nephrectomy, degree of sarcomatous renal involvement,
and survival were retrospectively analyzed.
Results: Fifty-four patients (72%) underwent nephrectomy during the initial resection, and 21 (28%) during a resection of a recurrent
or persistent tumor. The most common reason for nephrectomy was total encasement by sarcoma (n=40; 53%), followed by dense
adherence of the tumor to the kidney (n=21; 28%), and the direct invasion of the kidney by tumor (n=2; 3%). Pathology demonstrated
an absence of kidney invasion in the majority of cases (55 of 75; 73%). Renal capsular invasion was present in 11 of 75 (15%),
renal parenchymal invasion in 7 of 75 (9%), and renal vein invasion in 2 of 75 (3%) of cases. There were no significant differences
in survival based on degree of sarcoma involvement of the kidney, tumor grade, or whether the resection was for primary or
recurrent disease. The 53 patients who underwent a complete gross resection of all tumor had a significantly improved long-term
survival compared to the 20 patients who did not (50% versus 20% DFS at 5 years, respectively; p<0.001).
Conclusions: Decisions for concomitant nephrectomy during resection of retroperitoneal sarcoma should be based on whether this maneuver
will provide a complete resection of all gross tumor, in which case the long-term disease-free survival of 50% is comparable
to the reported 5-year survival of all patients with retroperitoneal sarcoma who are completely resected.

Twenty five subjects acclimatised to heat artificially were exposed to "basic effective temperatures" (BET) of 25.0 degrees, 29.6 degrees, 32.2 degrees, 33.3 degrees and 35.0 degrees C BET under conditions of both humid and dry heat. The object of the investigation was to ascertain the nature of effects of varying degrees of heat stress on mental alertness, associative learning, reasoning ability and dual-performance efficiency. A further aim was to determine the temperature levels at which impairment of psychological functions was severe enough to be of practical concern. The duration of each exposure was four hours, during which subjects performed physical exercise followed by rest every 30 min. It was found that all the psychological functions tested were adversely affected under extreme heat, and that a significant drop in various psychological functions was seen at effective temperatures of 32.2 degrees C and 33.3 degrees C in hot-humid and hot-dry conditions respectively. It is concluded that at the same effective temperatures the magnitude of the overall effect on psychological functions under humid conditions is relatively greater than that under dry conditions. 相似文献

This report describes a 35 year old male who presented with seizures after consuming 4-5 bottles of “ALL-OUT” a commercial composition of pyrethroid used as insecticides. Our case report supports authors reporting an association of pyrethroid poisoning with status epilepticus. 相似文献

The antibiotic vancomycin has been available since the 1950s but has been used more commonly since the early 1980s because of the widespread appearance of methicillin-resistant Staphylococcus aureus. Infectious Diseases Society of America guidelines recommend achieving vancomycin trough levels of 10 to 20 μg/mL. Usage of vancomycin in high dosages especially ≥4 g/d has led to an increase in the incidence of vancomycin-induced nephrotoxicity, particularly in patients with chronic kidney disease (CKD). This review focuses on the impact of vancomycin-induced nephrotoxicity in patients with CKD. Patients with CKD are at increased risk of developing acute kidney injury and subsequently requiring renal replacement therapy. There is substantial need for vancomycin pharmacokinetic studies to be performed in the population with CKD to develop an optimum vancomycin nomogram in these patients. At present, tight monitoring of vancomycin trough levels in the population with CKD is recommended to help prevent acute kidney injury and its associated high morbidity, mortality and health care costs. 相似文献

OBJECTIVES: Preliminary trials reflected the low prevalence of diabetes in Raica community consuming camel milk habitually. Our objective was to describe the prevalence and clinical factors associated with impaired fasting glucose (IFG), impaired glucose tolerance (IGT) and diabetes (DM) among adults (>or=20 years) in large population group. DESIGN: Population based, cross sectional study METHODS: 2099 participants from different villages of north-west Rajasthan were selected using stratified sampling of a representative Raica and non-Raica Community, consuming or not consuming camel milk. Demographic, clinical, anthropometric parameters were obtained and oral glucose tolerance tests were performed in all individuals to diagnose IFG, IGT and DM. Associations were investigated using multivariate logistic regression using SPSS Version 10.0. RESULTS: In the present study, the prevalence of diabetes in Raica community consuming camel milk (RCCM, n=501) was 0%; Raica community not consuming camel milk (RCNCM, n=554) was 0.7%; non-Raica community consuming milk (NRCCM, n=515) was 0.4% and non-Raica community not consuming camel milk (NRCNCM, n=529) was 5.5%. Stepwise logistic regression analysis showed that consumption of camel milk was statistically highly significant as protective factor for diabetes. Multiple logistic regression analysis revealed that camel milk consumption and community factor were associated with decreased prevalence of diabetes. CONCLUSION: Camel milk consumption and lifestyle have definite influence on prevalence of diabetes. Hence, adopting such life pattern may play protective role in preventing diabetes to some extent. 相似文献
