Two cases of a cavernous angioma with an encapsulated intracerebral hematoma are presented. In both instances, computed tomography scan showed a ringlike appearance with a nodular lesion. Cerebral angiograms of the two cases, however, were normal. The preoperative diagnosis for both cases was a brain neoplasm. The diagnostic problems that this type of vascular malformation presents and its role in the development of the encapsulated hematoma are discussed. 相似文献

Intracholecystic papillary neoplasms are newly defined precancerous lesions. According to Classification of the World Health Organization, they have four histological morphologies, which are biliary, gastric, intestinal, and oncocytic. This study evaluated 17 patients with resected intracholecystic papillary neoplasms in terms of histological, immunohistochemical, and copy number variation (CNV). The histological subtypes included 5 cases of low-grade (5 gastric) and 12 cases of high-grade (6 gastric and 6 biliary) neoplasms. Most cases showed high expression of MUC1, MUC5AC, and CK7, moderate expression of MUC6 and Ki-67, and low expression of CK20, MUC2, and CDX2. The CNV profile identified gain of 7q in 12%, and loss of 1p (18%), 5q (29%), 9p (35%), 12p (17%), 17p (24%), and 19p (18%). No CNVs were observed in low-grade neoplasms, whereas high-grade ones had increasing abnormalities. β-catenin was often expressed in the nucleus of neoplasms with gastric morphology, suggesting the involvement of the Wnt/β-catenin pathway. However, it was not expressed among those with biliary morphology, which instead exhibited high p53 expression. Neoplasms with biliary morphology showed more CNV changes (9p, 17p, 19p losses). Distinct immunological and CNV patterns were seen in both morphologies, suggesting differences in their pathogenesis. More CNVs accumulated with tumor progression. 相似文献

Both postprandial hyperlipidemia and hyperinsulinemia have been thought to play an important role in the development of atherosclerosis, and to be a potent risk factor for cardiovascular event. To examine effects of glycemic state on postprandial hyperlipidemia and hyperinsulinemia in patients with coronary artery disease (CAD), a total of 112 consecutive male patients with angiographically confirmed CAD were loaded with a high-fat and high-glucose test meal. CAD patients were divided into three groups as “non-diabetic”, “prediabetic”, and “diabetic” CAD groups. The serum triglyceride (TG) and remnant-like particle cholesterol (RLP-C) levels at the 6th hour in diabetic CAD group showed significantly higher than non-diabetic CAD group, and the incremental area under the curves (iAUCs) of these levels in diabetic CAD group were significantly greater than non-diabetic CAD group (TG, P = 0.0194; RLP-C, P = 0.0219). There were no significant differences in the iAUCs of TG or RLP-C between prediabetic and non-diabetic CAD group. The AUCs of plasma insulin levels or insulin resistance index (IRI): (AUCs of insulin) × (AUCs of glucose) as the insulin resistance marker were greater in diabetic CAD group than non-diabetic CAD group (insulin, P = 0.0373; IRI, P = 0.0228). The AUCs of serum TG or RLP-C levels showed a correlation with the AUCs of plasma insulin (AUC-TG, r = 0.5437, P < 0.0001; AUC-RLP-C, r = 0.6847, P < 0.0001), and they correlated well with the insulin resistance index (AUC-TG, r = 0.7724, P < 0.0001; AUC-RLP-C, r = 0.7645, P < 0.0001). We found that the insulin resistance showed a close relationship with postprandial hyperlipidemia in CAD patients. Diabetic, but not prediabetic state, may be a risk for postprandial impaired lipid metabolism in CAD patients. 相似文献

As most portal vein occlusion in hilar bile duct carcinoma is caused by tumor invasion to the portal vein, other mechanisms of its occlusion are very rare. We report the case of a 69-year-old man who underwent surgical resection for an advanced hilar bile duct carcinoma associated with unusual portal vein occlusion. Preoperative diagnosis was advanced hilar bile duct carcinoma with liver abscess and right portal vein occlusion due to tumor invasion. Extended right hepatectomy combined with resection of caudate lobe was performed. Intraoperatively, tumor invasion to the portal vein was not evident and resected margin of the right portal vein showed thrombosis and no evidence of malignancy histologically. To our knowledge, this is the first reported case of a patient with a combination of portal vein thrombosis and liver abscess in hilar bile duct carcinoma. Although portal vein occlusion due to thrombosis is an unusual complication in hilar bile duct carcinoma, the presence of liver abscess may be a useful diagnostic implication of this occlusion. 相似文献

We analyzed the disease-specific outcomes of adult ALL treated with cord blood transplantation (CBT) after myeloablative conditioning. Between October 2000 and November 2007, 27 adult patients with ALL were treated with unrelated CBT. All patients received four fractionated 12 Gy TBI and chemotherapy as myeloablative conditioning. The median age was 36 years, the median weight was 57 kg and the median number of nucleated cells was 2.47 x 10(7)/kg. All patients received a single and HLA-mismatched cord blood unit. The cumulative incidence of neutrophil recovery at day 30 and platelet recovery at day 200 was 92.6 and 92.3%, respectively. With a median follow-up of 47 months, the probability of EFS at 5 years was 57.2%. The 5-year cumulative incidence of TRM and relapse was 3.7 and 27.4%, respectively. These results suggest that unrelated CBT after myeloablative conditioning could be safely and effectively used for adult patients with ALL. 相似文献

Increasing recipient age is a well-known risk factor for graft-versus-host disease (GVHD) and treatment-related mortality
(TRM) and has a negative impact on allogeneic hematopoietic stem cell transplantation. Since the incidence of severe GVHD
after cord blood transplantation (CBT) is lower than that after transplants using bone marrow or mobilized peripheral blood
grafts from adult cells, we should expect better outcomes from CBT in older patients. To evaluate the feasibility and efficacy
of myeloablative unrelated CBT in patients aged between 50 and 55 years, we performed a retrospective comparison of 100 patients
with acute leukemia who received cord blood grafts at our institution. Nineteen older patients (median age, 52; range, 50–55)
and 81 younger patients (median, 36; range, 16–49) received a myeloablative conditioning regimen including 12 Gy of total
body irradiation and chemotherapy. GVHD prophylaxis included cyclosporine with (n = 96) or without (n = 4) methotrexate. There were no significant differences in the incidences of grades II to IV acute GVHD, extensive-type
chronic GVHD, TRM, and the probability of overall and disease-free survival between these groups. These results suggest that,
in patients with acute leukemia, myeloablative CBT might be as safe and effective in patients aged between 50 and 55 years
as in younger patients. 相似文献

We report herein a case of spindle cell type hepatocellular carcinoma responding to hepatic intra-arterial infusion chemotherapy. A 50-year-old woman was hospitalized for right epigastralgia. A computed tomography scan demonstrated cloudy liver tumor with a diameter of 12 cm in S5 and S8. Surgery was performed based on the diagnosis of liver tumor. However, because the tumor was also present in the left lobe, we did only a biopsy for a part of tumor. From the pathological findings, this was diagnosed as a spindle cell type hepatocellular carcinoma. After the operation, hepatic intra-arterial injection therapy of continuous infusion with 5-FU was conducted for two weeks. A small reduction in the tumor was seen with computed tomography after the completion of two courses. 相似文献

This study proposes that the mechanism of traumatic posterior dislocation of the hip (TPDH) is a brake pedal injury rather than a dashboard injury. A total of 168 cases of TPDH were treated during the past 10 years. Clinical records of 48 patients, who were drivers and suffered from a head-on collision accident, were examined. The right hip was involved in 45 cases. A total of 31 cases were not accompanied by knee injuries. In 11 cases with foot or ankle injuries and right hip dislocation, 10 had right foot or ankle injuries. If the mechanism of TPDH was a dashboard injury, the left hip would be involved more frequently and there would be more knee injuries. Our hypothesis about the mechanism is that, in a head-on collision, the driver presses desperately on the brake pedal with his right hip slightly flexed, adducted and internally rotated. 相似文献

PURPOSE: We report here our experience of brachytherapy using I-125 seeds for localized prostate cancer in 100 patients. MATERIALS AND METHODS: We carried out brachytherapy with I-125 seed permanent implants in 100 patients with localized prostate cancer between September 2003 and October 2004. Preplanning dosimetry was done using transrectal ultrasonic images obtained three or four weeks prior to treatment. Using transrectal ultrasound, we inserted I-125 seeds in the prostate through needles according to the preplanning diagram. We then examined the results on prostate CT performed one month later. RESULTS: It was necessary to describe transrectal ultrasonic image such as preplanning. There were several cases in which the source arrangement of the schedule was corrected immediately before the operation. In the examination after one month, the numerical value at the start of treatment initially was not satisfactory, but we eventually obtained a result that could to be evaluated. CONCLUSION: We carried out permanent implant brachytherapy for localized prostate cancer using I-125 seeds and reported our experience. 相似文献
