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

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 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

Ureteral obstruction due to retroperitoneal fibrosis secondary to a solitary internal iliac aneurysm

We report a case of ureteral obstruction due to retroperitoneal fibrosis secondary to a solitary left internal iliac aneurysm. It has been reported that as a cause of ureteral obstruction, an internal iliac aneurysm without aortic and/or common iliac aneurysms is very rare. In the present case, magnetic resonance imaging was a useful modality to diagnose retroperitoneal fibrosis secondary to an internal iliac aneurysm as a direct cause of ureteral obstruction. 相似文献

Summary. The ratio of serum pregnancy-specific β1 -glycoprotein (SP1) to the β-subunit of human chorionic gonadotrophin (β-hCG) before and after chemotherapy was measured in 12 patients with metastatic choriocarcinoma. The ratios before chemotherapy ranged between 0. 03 and 0. 75, with a mean value of 0. 34 (SD 0. 21). The ratio increased to over 1. 0 (1. 05–53. 3) after one or two courses of chemotherapy in seven of the 12 patients. These women achieved complete remission. In the other five patients who died of the disease due to drug resistance of the tumour, the ratio after chemotherapy was low (0. 04–0. 74) and tended to decline. These data suggest that the serum SPl/β-hCG ratio can be used to predict the prognosis of patients with choriocarcinoma. 相似文献

The effects of nonanal, trans-2-nonenal and 4-hydroxy-2,3-trans-nonenal on the formation of thromboxane B2 (TXB2), 12-hydroxy-5,8,10-heptadecatrienoic acid (HHT) and 12-hydroxy-5,8,10,14-eicosatetraenoic acid (12-HETE) from exogenous arachidonic acid in washed rabbit platelets were examined. Nonanal and trans-2-nonenal at concentrations ranging from 0.25 to 2 μm inhibited TXB2, HHT and 12-HETE formation, reducing the amounts of these three arachidonic acid metabolites by 50% at nonanal and trans-2-nonenal concentrations of approximately 0.25 μm. The inhibition of TXB2, HHT and 12-HETE formation induced by 4-hydroxy-2,3-trans-nonenal (50% inhibition by 4-hydroxy-2,3-trans-nonenal at a concentration of approximately 100 μm) was 400 times weaker than that induced by nonanal and trans-2-nonenal. These results suggest that nonanal and trans-2-nonenal can be modulators of platelet arachidonic acid metabolism by affecting the activity of cyclooxygenase and 12-lipoxygenase. 相似文献

Although biocompatibility of biodegradable stents is controversial, stents made of high molecular weight poly- l -lactic acid (PLLA) are thought to be the most promising. We investigated the biocompatibility of PLLA stents histologically and angiographically in porcine coronary arteries. The Igaki-Tamai stent is made of PLLA monofilaments (molecular mass 183 kD) with a zigzag helical coil design. Fourteen PLLA stents in 6 pigs and 9 Palmaz-Schatz half stents in 9 pigs were implanted in 15 normocholesterolemic pigs. Stents were mounted on a delivery catheter, and were implanted percutaneously into coronary arteries. Coronary angiography was performed before and immediately after stenting, at 2 and 6 weeks in five PLLA pigs and nine Palmaz-Schatz pigs. Histological studies were performed in PLLA pigs: 2 pigs at 2 weeks, 3 pigs at 6 weeks, and 1 pig at 16 weeks with hematoxylin-eosin and elastica van Giesons stains. All PLLA stents were successfully delivered. No stent thrombosis was detected in either group. There were no significant differences in minimal lumen diameter (MLD) or percent diameter stenosis between the PLLA and Palmaz-Schatz stent groups immediately after implantation, or at 2 or 6 weeks after implantation. Histological studies at 2, 6, and 16 weeks revealed no inflammation and minimal neointimal coverage on the PLLA stent struts. The PLLA stent maintained its structure for up to 16 weeks. These results suggest sufficient biocompatibility and strength of PLLA biodegradable stents in porcine coronary arteries. Clinical trial is now underway to validate the safety and usefulness of PLLA stents in humans. 相似文献

HARUO SENO MD MASAHIRO SHIBATA MD AKIHIKO FUJIMOTO MD KAORU KOGA MD HIROSHI KANNO MD HIROSHI ISHINO MD 《Psychiatry and clinical neurosciences》1998,52(6):567-570
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
