The prognostic factors were retrospectively analyzed in 30 patients aged 70 years or over with supratentorial malignant gliomas treated by surgery in our hospital. The histological diagnosis was confirmed as grade 3 in 13 patients and grade 4 in 17. Seventeen patients received adjuvant radiation therapy. Only 10 patients underwent chemotherapy. Survival time was analyzed with the Kaplan-Meier method. Prognostic factors were obtained from the Cox proportional hazards model. Univariate analysis showed preoperative Karnofsky performance status (KPS) score of 70 or greater and radiation therapy were significantly associated with longer survival. However, multivariate analysis revealed that preoperative KPS score of 70 or greater was the only independent prognostic factor and radiation therapy lost its significance due to selection bias. Neurological deterioration and medical complications occurred in six and seven patients, respectively. Performance status rather than histological grade is the key prognostic factor in elderly patients with supratentorial malignant gliomas. Patients with good preoperative KPS score should be aggressively treated with extensive resection and radiotherapy. 相似文献

We report an extremely rare tumor presenting with rhabdoid features in the left temporoparietal lobe near the trigone in an
18-year-old Japanese man. This tumor mainly consisted of medium to large round cells that proliferated diffusely and incoherently
with a scant extracellular matrix. These tumor cells had an eccentric nucleus and an eosinophilic cytoplasm containing inclusion
bodies and bundles of intermediate filaments. The nuclei of these cells were vesicular with prominent nucleoli. This tumor
had an area appearing to be diffuse astrocytoma peripherally and lacked a primitive neuroectodermal tumor component, a mesenchymal
component, and epithelial differentiation. INI expression, which is not observed in atypical teratoid/ rhabdoid tumor (AT/RT),
was found in this tumor. From these findings, we concluded that this tumor was not AT/RT but an astrocytic tumor with rhabdoid
features. We also concluded that the tumor cells exhibiting rhabdoid features had secondarily arisen from the peripheral area
presenting an appearance of diffuse astrocytoma. 相似文献

Using computed tomography (CT), measurements of whole liver volume have been used for the assessment of pre-operative functional reserve in cirrhotics. However, measurements of hepatocyte volume, which exclude stromal fibrous tissue, are considered to more directly reflect hepatic functional reserve. We investigated the relationship between total hepatocyte volume and each of the parameters of conventional liver function. Indocyanine green (ICG) tests and blood analyses for the assessment of liver function were performed prior to surgery in cirrhotic patients with liver tumours. Pre-operative liver volume was determined by integrating images of each liver area obtained by CT. Liver area was measured by an image processing program that traced the profile of the liver image while excluding the tumorous area. Sections of normal tissue stained by the haematoxylin-eosin method, were obtained from the resected liver. Using these sections, a hepatocyte area: whole tissue area ratio was calculated using the image processing program, by tracing the profiles of the hepatocyte nodules. The total volume of hepatocytes was then calculated by multiplying the liver volume by this ratio. The hepatocyte volume per unit bodyweight was significantly correlated with ICG tests and with many other parameters of normal liver function. However, the liver volume per unit bodyweight was correlated only with the plasma ICG disappearance rate and with the blood platelet count. These observations suggest that the functional reserve of the cirrhotic liver is assessed more precisely by hepatocyte volume than by liver volume. 相似文献

A case of a persistent sciatic artery in a 68-year-old farmer, showing symptoms of acute arterial occlusive lesion of the
right lower limb is presented. The persistent sciatic artery was joined to the internal iliac artery proximally and to, the
popliteal artery distally. The anomalous artery was occluded by atheromatous thrombi. The superficial femoral artery was hypoplastic
and terminated in the descending genicular artery at the midthigh level. A successful bypass was performed between the common
femoral artery and proximal popliteal artery utilizing a woven teflon graft. 相似文献

A 63-year-old Japanese man had phaeohyphomycosis that occurred as a solitary subcutaneous nodule on the dorsal aspect of his left hand. In the nodule there were foci of mixed granulomatous and suppurative infiltrations circumscribed by thick fibrous tissue reaction. The foci contained short septate hyphae and occasionally small rounded aggregates of irregularly branched septate hyphae, both of which were nonpigmented or rarely weakly pale brown. Fungal culture from the nodule was positive for a dematiaceous mold. The mycologic features of the mold were typical of Phialophora repens. The infection was successfully treated by excision of the nodule. This is the second reported case of infection due to P. repens. 相似文献

Objective: The objective of this study was to determine the effects of a continuous infusion of low-dose hANP on the lungs during cardiac surgery in patients under cardiopulmonary bypass (CPB).Methods: We analyzed 30 consecutive cases of cardiac surgery performed at our hospital from 2007–2008. The patients were divided into a group that received hANP (hANP group) or a group that received saline and no hANP (N-hANP group). We measured various parameters before and after surgery using a PiCCO monitor.Result: There were no differences in the preoperative characteristics between the groups, although urine volume during the operation was significantly greater in the hANP group. After surgery, there were no significant differences between the groups in cardiac output index (CI), global enddiastolic volume index (GEDVI), intrathoracic blood volume index (ITBI), pulmonary blood volume index (PBI), extravascular lung water index (ELWI) and pulmonary vascular permeability index (PVPI), total protein, and creatine. In contrast, interleukin-6 (IL-6) and renin were significantly lower, and albumin was significantly higher in the hANP group.Conclusion: We found that low-dose hANP during open cardiac surgery inhibited the secretion and plasma activity of IL-6 and renin. Although there were no differences in lung circulatory parameters such as the amount of fluid in the pulmonary blood vessels between the two groups, we believe that the strong diuretic effect of hANP reduced third-space fluid retention caused by CPB. 相似文献
