We report a case of leiomyosarcoma of the renal vein, which is a rare tumor with no more than 30 cases found in the published English language literature. This case demonstrates encasement of the renal artery by the tumor mass, a previously unreported manifestation. The present study could be useful in considering this rare tumor in the differential diagnosis of renal hilar tumors. 相似文献

Summary: Matrix metalloproteinases (MP) are important candidates for the degradation of extracellular matrix, but the role of MP in the diseased kidney remains poorly understood. to examine the significance of urinary MP, we first investigated the characteristics of MP in normal rat urine and renal cortex, and then evaluated the urinary MP activity in anti-thymocyte induced glomerulonephritis (Thy.1 GN). Metalloproteinase activity was measured as the EDTA-inhibitable degradation of [3 H] gelatin. the enzyme was purified from urine and the renal cortex homogenate in normal Wistar rats by using several chromatographic and gel filtration methods. Both materials contained the identical molecular weight (Mr 126 kDa by gel permeation method) of gelatin-degrading enzymes, the activity of which was inhibited by metal chelating agents and reactivated by ZnC12 but not by other proteinase inhibitors. Thy.1 GN was induced by intravenous injection of rabbit anti-thymocyte serum into rats, and daily urine was collected at sequential time points. Urinary MP activity was markedly reduced soon after the serum injection, and returned to the control level in 9 weeks. Conversely, urinary MP-inhibitor activity (Mr 30 kDa), determined as inhibiting activity against MP derived from renal cortex, showed serial changes strikingly reflected as urinary MP activity. These findings suggested that rat urine contained the MP which seemed to be derived from the renal cortex, and the urinary MP activity was decreased in Thy.1 GN model, probably due to the presence of MP-inhibitor. As urinary MP is likely to reflect intra-renal MP, the evaluation of urinary MP may be useful to search metabolic alteration of extracellular matrix in the diseased kidney. 相似文献

Abstract Mini Mental State Examination (MMSE), Brief Psychiatric Rating Scale (BPRS) and subscales of the BPRS were performed on 73 elderly inpatients (mean age: 67.9 years; standard deviation: 7.2; range: 60–89) diagnosed with DSM-III-R chronic schizophrenia. Forty of the subjects were men and 33 were women. A significant negative correlation was observed between MMSE and the age, factor negative, factor depressive, and total score of BPRS. We believe, however, that it is relatively sufficient to screen for demented illness of schizophrenics using MMSE when considering the age and the psychiatric symptoms (especially negative or depressive symptoms). Forty-eight (66%) of the 73 patients were categorized as 'demented' by MMSE. These results suggest that the aged inpatients with schizophrenia in a hospital showed certain kinds of cognitive deficits (including senile dementia) more frequently than the general population. 相似文献

This study investigated the prevalence and clinical significanceof anti-ribosomal P protein (anti-P) antibodies in patientswith systemic sclerosis (SSc). Serum samples from 150 patientswith SSc were examined by indirect immunofluorescence, ELISAand immunoblotting. Anti-P antibodies were detected in four(3%) patients with SSc. Three of the four patients showed SSc/SLE(systemic lupus erythematosus) overlap syndrome, but psychiatricdisorders were not observed in these patients. By longitudinalimmunoblotting analysis one patient, who was initially diagnosedwith SSc, later developed anti-P antibodies along with clinicalmanifestations of SLE. Our data suggest that anti-P antibodiesare uncommon in SSc and that the presence of anti-P antibodiesin patients with SSc indicates an overlap with SLE.

We describe a practical technique of superior turbinectomy followed by posterior ethmoidectomy as a less invasive procedure for two-surgeon technique on endoscopic endonasal transsphenoidal surgery. After identification of the superior turbinate and the sphenoid ostium, the inferior third portion of the superior turbinate was coagulated and resected. This partial superior turbinectomy procedure exposed the posterior ethmoidal sinus. Resection of the bony walls between the sphenoid and posterior ethmoid sinuses provided more lateral and superior exposure of the sphenoid sinus. This technique was performed in 56 patients with midline skull base lesions, including 49 pituitary adenomas and 7 other lesions. Meticulous manipulation of instruments was performed in all cases without surgical complications such as permanent hyposmia/anosmia or nasal bleeding. Our findings suggested that the partial superior turbinectomy followed by retrograde posterior ethmoidectomy is a simple and safe technique providing a sufficient surgical corridor for two-surgeon technique to approaching midline skull base regions, mainly involving pituitary adenomas. 相似文献

We describe three cases with acute middle cerebral artery (MCA) occlusion. From the pre-operative MRI, including three-dimensional turbo spin-echo sequences using T1WI and T2WI, we assessed both thrombus configuration and arterial anatomy at the MCA bifurcations. For efficient endovascular thrombectomy, we identified the applied MCA segment 2 (M2) branch, in which the main thrombus was buried. Sufficient recanalization after a single pass was achieved and the patients made a marked recovery. Although mechanical thrombectomy for M2 occlusion has not been of proven benefit, the endovascular procedure based on three-dimensional turbo spin-echo imaging is useful for more complete thrombus removal at MCA bifurcations. 相似文献

The object of this study was to determine the frequency and characteristics of altered paraumbilical vein in the hepatic parenchyma, developed from portal hypertension, using computed tomography (CT). Two hundred and ninety-two patients who presented with portal hypertension from 1986 to 1996 were studied retrospectively. The pathway of the dilated para-umbilical vein was demonstrated by contrast-enhanced CT. Thirty-one (11%) patients had a dilated para-umbilical vein arising from the left portal vein into the falciform ligament. In 24 (77%) of these patients, the para-umbilical vein followed the expected route, passing through the fissure of ligamentum teres hepatis. The remaining seven patients (23%) displayed the unusual pathway, with the vein arising from the left branch of the portal vein and passing into the hepatic parenchyma. In these seven patients, four had one collateral vein, and three patients had two collateral veins in the liver parenchyma. The dilated para-umbilical vein frequently passes through the hepatic parenchyma in patients with portal hypertension. 相似文献

We evaluated the clinical significance of measurement of urinary neopterin levels in primary immunodeficiencies and persistent infections exclusively at afebrile or asymptomatic periods. Despite the examinations at afebrile or asymptomatic periods, urinary neopterin levels were elevated in some patients with primary immunodeficiencies and in patients with persistent infections of human immunodeficiency virus (HIV) or Epstein-Barr virus (EBV). Therefore, urinary neopterin measurement at afebrile periods will be useful as one of the screening tests in the detection of such disorders among children with occasional episodes of infections. 相似文献

This study reports an unusual case of acute leukemia which was diagnosed as hemophilia A on initial admission for leukemia. A 3 year old boy was admitted to Kagoshima University Hospital with anemia. He was diagnosed as acute lymphoblastic leukemia. At the same time he was revealed to have severe hemophilia A− without any previous episodes of severe bleeding tendency or family history of this disease. The laboratory investigation showed his mother to be a carrier of hemophilia A. Although there are many cases of hemophilia which have developed malignant tumors, most of them were caused by association with human immunodeficiency virus (HIV) infection. Only five cases with coexistence of leukemia and hemophilia without HIV infection have been reported and the present case is the first one in Japan. At this stage, hemophiliacs are not necessarily regarded to be a population at risk for the development of leukemia. Furthermore, no particular subtype of leukemia was characterized among these patients in the literature. 相似文献
