An 8 year old girl with acute disseminated encephalomyelitis (ADEM) is described. Elevated serum antibody titers suggested recent Mycoplasma pneumoniae infection. T2-weighted image of magnetic resonance imaging (MRI) disclosed multiple lesions of high signal intensity in bilateral basal ganglia and thalami as well as in the white matter. Postcontrast T1-weighted image revealed an enhanced lesion in the deep white matter. She showed rapid clinical improvement in response to corticosteroid therapy. The lesions had disappeared completely on MRI performed 10 weeks after the onset. ADEM is believed to be a demyelinating disorder of probable autoimmune etiology. MRI findings in this case may support the hypothesis that the primary pathological event is vascular injury and demyelination occurs only as a secondary phenomenon. 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

BACKGROUND: Retroperitoneal lymph node dissection (RPLND) following induction chemotherapy has been considered a critical component in the comprehensive management of advanced non-seminomatous germ cell tumors (NSGCT). The objectives of the present study were to review the clinical outcome of patients who underwent RPLND and to evaluate the probability of necrosis alone, based on some readily available clinical data for these patients. METHODS: Forty-seven consecutive patients with NSGCT were treated with first-line chemotherapy at our institution between January 1993 and September 2002. Twenty-four of these patients, who underwent RPLND with normal values of tumor markers after induction chemotherapy, were included in the study. The cause-specific survival rate was calculated using the Kaplan-Meier method. Various predictive factors for the histology were analyzed using multivariate analysis. RESULTS: The pathological findings at resection were necrosis alone in 62.5% of cases, teratoma in 25.0%, and viable cancer in 12.5%. The cause-specific 3-year survival rate of patients who underwent complete and incomplete resection was 100% and 50.0%, respectively. Among several clinical factors, prechemotherapy tumor size less than 50 mm was found to be an independent predictor of necrosis alone (hazard ratio = 4.45, P= 0.04). CONCLUSION: Metastatic tumor size before chemotherapy appears to be one of the most important factors for the prediction of necrosis alone in the resected specimens of RPLND. The prognosis of patients might be influenced by the degree to which resection has been completed. 相似文献

Effects of glycyrrhizin on immune-mediated cytotoxicity 总被引:10,自引:0,他引:10
MASAHIDE YOSHIKAWA YUJI MATSUI HIROSHI KAWAMOTO NORIE UMEMOTO KAZUMI OKU MASAKI KOIZUMI JUNICHI YAMAO SHIGEKI KURIYAMA HIROSHI NAKANO NOBUMICHI HOZUMI SHIGEAKI ISHIZAKA HIROSHI FUKUI 《Journal of gastroenterology and hepatology》1997,12(3):243-248
Intravenous administration of glycyrrhizin is known to decrease elevated plasma transaminase levels in patients with chronic viral hepatitis, in which immune-mediated cytotoxicity by cytotoxic T lymphocytes and tumour necrosis factor (TNF)-α is considered to play an important pathogenic role. However, the immunological interpretation of the transaminase-lowering action of glycyrrhizin is not known. Studies were performed to elucidate this action immunologically by assessing the effects of glycyrrhizin on immune-mediated cytotoxicity using an antigen-specific murine CD4+ T hybridoma line, which exhibits cytotoxicity against antigen-presenting cells after stimulation with specific antigen, and a murine TNF-α-sensitive fibroblast line. Glycyrrhizin inhibited the cytotoxic activity of the T cells against antigen-presenting cells and also suppressed TNF-α-induced cytotoxicity in the TNF-α-sensitive cell line in vitro. These results suggest that the decrease of elevated transaminase levels by glycyrrhizin in patients with chronic viral hepatitis is mediated in part by inhibition of immune-mediated cytotoxicity against hepatocytes. 相似文献

We report the case of a female patient with bilateral metachronous adrenocortical cancer who survived long-term after adrenalectomy. In 1991, the patient underwent left adrenalectomy to remove a huge adrenal mass (10 x 9 cm) displaying no hormonal abnormality. Histological diagnosis was adrenocortical cancer. A right adrenal mass (7 x 6 cm) was found 4 years after left adrenalectomy. Right adrenalectomy was performed, and histological diagnosis was again adrenocortical cancer. The patient remains alive with no evidence of disease 8 years after last surgery. 相似文献

Abstract: Thirteen patients, who had recurrent esophageal varices after esophageal transection or esophagoproximal gastrectomy were treated by endoscopic injection sclerotherapy. Four patients successfully underwent emergency sclerotherapy to control active variceal hemorrhaging. Three of these patients and the remaining nine patients (including six rebleeding patients who were conservatively treated) underwent elective sclerotherapy. None of the patients had variceal rebleeding in the follow-up study with sclerotherapies. Only one patient with recurrent varices did not undergo any additional sclerotherapy following emergency treatment. In this study, no deaths occured nor any major complications. Minor complications such as low grade fever and chest pain were observed, but they were transient and disappeared within 2 or 3 days without specific treatments. It is concluded that endoscopic injection sclerotherapy is considered to be the most effective procedure for recurrent varice following surgery. 相似文献

Three patients who had undergone implantation of a rate modulated, afrial sensitive RS4 pacemaker, with a single orthogonal lead underwent replacement of a depleted unit with a DDD pulse generator, reusing the original lead with an adapter that allowed conversion of the bipolar atrial electrode into unipolar configuration. The mean atrial electrogram amplitude was 1,8 mV and no significant atrial sensing defects were found during Holler monitoring. As the RS4 pulse generator is no longer available, continued VDD pacing is possible by replacing it with a DDD pulse generator using the previously implanted single lead system. 相似文献

A 31-year-old, previously normotensive healthy man developed right flank pain and was admitted to a medical service. Right renal infarction was suspected by enhanced abdominal computed tomography (CT) and arteriography. Fourteen days after the onset, he was transferred to the Oita University Hospital, Oita, Japan. Renal angiography revealed an isolated renal artery dissection causing renal atrophy due to main stem narrowing of the right renal artery. Renogram and renal scintigram with (99m)Tc-diethylene triamine pentaacetic acid revealed a remarkable decline in the glomerular filtration rate and almost no uptake in the right kidney. Four months later, in spite of our belief that functional recovery could not be expected, intravenous pyelography and enhanced abdominal CT scans revealed a functioning right kidney that had spontaneously recovered from the renal artery dissection through conservative management. 相似文献
