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

We report on a case of coexistence of replacement lipomatosis with xanthogranulomatous pyelonephritis (XGP) in the same kidney associated with staghorn calculi. A 63-year-old man was admitted to hospital complaining of a right abdominal mass. Computed tomography (CT) showed renal parenchymal atrophy with extremely increased perirenal fat. Right nephrectomy was performed. Postoperative diagnosis was renal replacement lipomatosis with XGP. Renal replacement lipomatosis and XGP have several similarities in terms of clinical background and CT findings. Sometimes it is difficult to differentiate them from malignant diseases. It is extremely rare that both conditions coexist in the same kidney. To our knowledge, only one such case has been reported. 相似文献

We report on two cases of women with locally advanced squamous cell carcinoma of the urethra. Patient 1 also displayed regional lymph node metastasis. Treatment comprised combined radiotherapy to 60 Gy and chemotherapy with 5-fluorouracil and cisplatin. Complete response was obtained in both patients, including the inguinal lymph nodes of Patient 1. Patient 1 experienced recurrent inguinal lymph node metastasis on the contralateral side at 42 months after initial treatment, and the same treatment was performed followed by surgical excision. Both patients remain alive with no evidence of disease, at 12 months after recurrence in Patient 1, and at 27 months after treatment in Patient 2. 相似文献

BACKGROUND: Local force distribution supporting the bodyweight of infants with Down syndrome (DS) appears to be different from that of healthy controls. The purpose of the present study was to establish methods to assess this force distribution and to allow therapeutic evaluation of neurological development in DS infants prior to walking. METHODS: Contact pressure distribution patterns in supine and prone positions were measured by photoelastic methods and were compared between DS infants and healthy controls. The DS group included eight subjects, seven with regular trisomy 21, and one with a Robertson translocation. The controls consisted of 14 neonates, four 4-month-old infants and eight 7-month-old infants. RESULTS: In both groups, head loading ratio decreased as age advanced but the decrement was less in the test group than in the control group. When the bodyweight loading ratios were measured in two different lying positions, that is, prone and supine, the ratios for prone generally tended to be smaller than those for supine in the controls. This kind of difference between prone and supine was not seen in the DS group. The bodyweight is somewhat sustained with limbs and the limbs loading ratios in the DS group were always significantly lower than in the controls. CONCLUSION: Coordinated development of weight-supporting limbs seems to be poor in the DS group. 相似文献

The aim of the present study was to clarify whether bile acids influence chemiluminescence (CL) in the liver in vivo. Hepatic CL was determined on the surface of the liver of anaesthetized rats by using a photon counter. In normal rats, hepatic CL was significantly decreased 30 min after enteral administration of chenodeoxycholic acid (CDCA) or deoxycholic acid (DCA), but returned to its initial level 3 h later, after part of the CDCA administered was metabolized. Ursodeoxycholic acid (UDCA) and cholic acid had no effect on CL. In contrast, hepatic CL was markedly increased 30 min after CDCA or DCA administration in rats given either buthionine sulphoximine (BSO), an inhibitor of γ-glutamylcysteine synthetase, or diethyldithiocarbamate (DDC), an inhibitor of both superoxide dismutase and glutathione peroxidase. Chenodeoxycholic acid further increased the CL of BSO- or DDC-treated rats during inhalation of oxygen via a tracheal cannula. Coadministration of UDCA eliminated the effects of CDCA on the hepatic CL of normal and BSO- or DDC-treated rats with or without oxygen inhalation. We conclude that cytotoxic bile acids, such as CDCA, increase CL in the antioxidants-depleted or oxidative-stressed liver in vivc, but that UDCA prevents CDCA from developing CL. 相似文献

Background. The microvasculature plays an important role in the pathogenesis of psoriatic skin lesions. Our purpose was to try to define a psoriatic pattern in the nailfold capillary, to clarify the relationship between nailfold capillary microscopic changes and nail involvement and to note the general clinical features of psoriasis. Methods. Image analysis of nailfold capillaries was performed in 62 patients with psoriasis. The capillary pattern was defined statistically comparing it with that of 51 healthy volunteers. We attempted to differentiate the psoriatic pattern from normal controls with “canonical discriminant analysis.” Results. Forty-nine of 62 patients with psoriasis could be differentiated from normal controls by our definition of psoriatic pattern that was significantly correlated with periungual psoriatic plaque, nail pitting, onycholysis, and the extent of the involved area. Conclusions. Our data suggest that nailfold capillary changes reflect microvascular changes of psoriasis and that the nailfold capillary pattern is a useful tool in evaluating nail involvement and the severity of psoriasis. 相似文献

Abstract The prognosis of 174 patients with cirrhosis during the 1980s (1981–89) was analysed. The estimated survival rates were 87.3% in 3 years and 68.5% in 5 years. During the follow-up period, 58 patients died: 20 of hepatocellular carcinoma (37.7%); 11 of hepatic failure (20.8%); eight of gastrointestinal bleeding (15.1%); and 14 of other causes (26.4%). Multivariate analysis revealed that serum albumin, indocyanine green retention rate at 15 min and white blood cell count were significantly associated with prognosis. The results were also compared to our previous study covering the 1970s (1971–80). The estimated survival rate was significantly improved compared to that during the 1970s (54.3% in 5 years, P < 0.001). In the 1980s, hepatic failure mortality significantly decreased ( P < 0.01), and non-liver-related mortality significantly increased ( P < 0.05). In summary, the prognosis of cirrhosis has improved in recent years, and changes of death cause and prognostic factors were observed. It was concluded that to evaluate the severity and prognosis of cirrhosis, new indices and appropriate classification were necessary. 相似文献

The objective of this study was to determine whether paracetamol (acetaminophen) affects the outcome of children with fever due to bacterial infectious disease. A total of 208 outpatients aged 6 months to 15 years with pyrexia due to bacterial infection who had been examined at the Fujimoto Children's Hospital from March 1992 to May 1992. The number of antipyretic doses of paracetamol (10 mg/kg) a day received within 3 days of illness in the patients with acute fever (≥ = 38°C) was investigated. In this study, the patients were divided into two groups: (i) the pneumonia group, which consisted of 101 patients who were subsequently diagnosed as having pneumonia during their illness and (ii) the control group, which consisted of 107 patients who were subsequently diagnosed as having illness with fever that did not progress to pneumonia. The mean number of daily doses was significantly higher for the pneumonia group (2.52 ± 0.80) than for the control group (1.37 ± 0.72, P < 0.001). There was no significant difference between the pneumonia group and the control group in body temperature during acute fever (38.7 ± 0.65 vs 38.8 ± 0.54°C). The data suggest that frequent administration of antipyretics to children with infectious disease may lead to a worsening of their illness. 相似文献

We describe the present view of performing diagnostic endoscopic ultrasonography guided fine needle aspiration biopsy (EUS‐FNAB). In the pancreatic diseases, our application of EUS‐FNAB for pancreatic disease has been as follows: as to the operable cases, EUS‐FNAB should not be performed through any pathway penetrating the duodenum and the stomach. EUS‐FNAB is contraindicated in cystic diseases. As to the cases diagnosed as inoperable with various imaging modalities, EUS‐FNAB should be performed to obtain the pathological evidence. In gastrointestinal disorders, all intramural diseases are appropriate indications for this procedure. Even if the target lesion is in the far oral part of the large intestine, we perform EUS‐FNAB by the special method described in this paper. Lymphadenopathy for appropriate cases is one of the best cases in which to perform EUS‐FNAB. Mediastinal lymph node metastasis influences the treatment plan of lung cancer; the application of this treatment is increasing in our institute. 相似文献
