Expansion of selection criteria for patients with hepatocellular carcinoma in living donor liver transplantation.

In the present study, the results of living donor liver transplantation (LDLT) for 125 hepatocellular carcinoma (HCC) patients were analyzed to determine optimal criteria exceeding the Milan criteria (MC) but still with predictably good outcomes. On the basis of pretransplant imaging studies, 70 patients met the MC, and 55 patients did not. Patients who exceeded the MC but presented with 相似文献   

Results of low- and high-dose-rate interstitial brachytherapy for T3 mobile tongue cancer.

PURPOSE: To evaluate the treatment results of low-dose-rate (LDR) and high-dose-rate (HDR) interstitial brachytherapy (ISBT) for T3 mobile tongue cancer. MATERIAL AND METHODS: Between 1974 and 1992, 61 patients with T3 mobile tongue cancer were treated with LDR ISBT using (192)Ir hairpins with or without single pins. In addition, between 1991 and 1999, 14 patients were treated with HDR ISBT. For nine patients treated with ISBT alone, the total dose was 59-94 Gy (median 72 Gy) within one week in LDR ISBT and 60 Gy/10 fractions/5 days in HDR ISBT. For 66 patients treated with a combination therapy of external beam radiotherapy (EBRT) and ISBT, the total dose was 12.5-60 Gy (median 30 Gy) of EBRT and 50-112 Gy (median 68 Gy) within 1 week in LDR ISBT or 32-60 Gy (median 48 Gy)/8-10 fractions/5-7 days in HDR ISBT. RESULTS: The 2- and 3-year local control rates of all patients were both 68%. The 2- and 3-year local control rates of patients treated with LDR ISBT were both 67%, and those with HDR ISBT were both 71%. The local control rate of patients treated with HDR ISBT was similar to those with LDR ISBT. CONCLUSIONS: ISBT for T3 mobile tongue cancer is effective and acceptable. The treatment result of HDR ISBT is almost similar to that of LDR ISBT for T3 mobile tongue cancer.     

Bilateral symmetric tonic posturing suggesting propagation to the supplementary motor area in a patient with precuneate cortical dysplasia.

We report a patient manifesting seizures with bilateral symmetric tonic posturing, which were markedly reduced after resection of the left precuneus. A 16-year-old man had sudden onset, complex partial seizures with bilateral symmetric tonic posturing since the age of eight years. Magnetic resonance fluid-attenuated inversion-recovery imaging revealed a hyperintense lesion in left precuneus. In almost all focal seizures recorded during an invasive EEG evaluation, ictal onset was detected from the inferomesial aspect of the lesion, but fast paroxysmal discharges from the ipsilateral supplementary motor area (SMA) were observed just before the clinical onset. After surgical excision of the EEG onset zone, including the lesion, seizure frequency was markedly (> 95%) reduced. By the 20th month after surgery, there were only brief nocturnal seizures involving slight elevation of both shoulders and slight abduction of both arms, with preservation of consciousness occurring once every few days. Invasive EEG findings and surgical outcome suggested that the epileptic activity originating from the epileptogenic zone may have propagated to the symptomatogenic zone including mainly the ipsilateral SMA. In summary, we report an interesting case of bilateral symmetric tonic posturing suggesting propagation to the SMA. MRI and invasive EEG confirmed the epileptogenic focus as a precuneate cortical dysplasia lesion.[Published with video sequences].     

Computerized tomography observation of a calcifying cystic odontogenic tumor with an odontoma: case report.

The calcifying cystic odontogenic tumor is a rare benign odontogenic lesion. This report documents a case of this lesion associated with odontoma arising from the anterior maxilla in a 14-year-old boy. The diagnosis was confirmed based on computerized tomography findings, which clearly depicted the internal structures obscured in conventional images.     

Eosinophilic gastroenteritis in the esophagus, stomach, and small intestine in a patient with a choking feeling in the esophagus]

A 75-year-old man was admitted to our hospital with the chief complaint of a choking feeling around the esophagus. Laboratory examinations revealed eosinophilia, and high levels of serum immunoglobulin (Ig) E. A computed tomography scan (CT) showed wall thickening of the esophagus and terminal ileum, and ascites around the liver. An endoscopic examination revealed mild mucosal edema in the esophagus, stomach, and small intestine. Biopsy specimens showed diffuse eosinophilic infiltration in the mucosa. We therefore diagnosed eosinophilic gastroenteritis. Oral prednisolone relieved clinical conditions and the CT image improved. This case was considered valuable, because there have been few reports of eosinophilic esophagitis in Japan.     

The Japanese experience with metabolic imaging in the clinical setting

Conclusions  Reduced utilization of fatty acids at rest often is observed in severely ischemic myocardium and possibly postischemic myocardium despite normal perfusion at rest. The role of metabolic imaging in identifying postischemic insult as ischemic memory imaging has been the focus of recent investigations. A number of reports from Japan show quite acceptable diagnostic accuracy of BMIPP imaging for detecting coronary patients without prior MI. In addition, recent data indicate that BMIPP imaging has prognostic value when applied in patients with documented or suspected coronary disease. The major advantage of BMIPP imaging is to demonstrate ischemic myocardium as an area of altered metabolism at rest. Thus this study is of clinical importance for elderly patients or for patients not suitable for a stress study. Furthermore, this radiopharmaceutical tracer may hold promise in demonstrating early alteration of energy metabolism in a variety of myocardial disorders.     

Risk of gallstones following gastrectomy in Japanese men

The risk of gallstones developing after gastrectomy in middle-aged Japanese men was investigated in a study of 2,738 men aged between 48 and 56 years who underwent both gallbladder ultrasonography (US) and a barium study of the upper digestive tract. It was revealed that 61 men had gallstones, 37 had had their gallbladder removed previously, and 55 had a history of gastrectomy. The prevalence of gallstones was 3.5 times higher in the men who had previously undergone gastrectomy (7.7%) than in those who had not (2.2%) (P=0.03). Moreover, gallstones tended to be more prevalent in those who had undergone Billroth II gastrectomy (12.5%) compared with those who had undergone Billroth I gastrectomy (5.6%); however, the difference was not significant. These results indicate that gastrectomy using either Billroth I or Billroth II reconstruction predisposes to gallstone formation. Nevertheless, it was estimated that prior gastrectomy was responsible for no more than 5% of gallstones in the study population.     

Chemo-endocrine therapy in patients with stage D2 prostate cancer

There have only been a few studies of chemo-endocrine therapy compared with endocrine therapy alone in newly diagnosed prostate cancer patients. We assessed the effects of these two therapies by comparing long-term survival rates. One hundred and twenty-nine patients were entered in this study between November 1977 and March 1992. Seventy-seven patients were treated with endocrine therapy alone. Other 52 patients received chemo-endocrine therapy, which included orchiectomy and/or diethylstilbestrol diphosphate (DES-DP) plus Cisplatin, with or without other cytotoxic agents. All patients had bone metastasis at the beginning of the study. There was a significant difference in survival between patients who received endocrine therapy and chemo-endocrine therapy (P = 0.0078). That is, survival rate was superior for the chemoendocrine therapy patients throughout the entire follow-up period. These data suggest that early chemo-endocrine therapy containing Cisplatin, with or without maintenance chemotherapy, is a potentially effective treatment for newly diagnosed metastatic prostate cancer and is worth further investigation via a randomized trial.     

Early gastric cancer manifested as brain metastasis: Report of a case

A case of early gastric cancer, limited to submucosal layer, which was manifested as cerebral metastasis is presented herein. A 47-year-old man was admitted to Nagaoka Chuo General Hospital with convulsions and a disturbance in consciousness, where a computed tomography (CT) scan revealed a cerebral tumor in the left temporal lobe. The resected tumor was identified as a metastatic adenocarcinoma. Further investigation revealed gastric cancer involving the posterior wall of the cardia. At laparotomy, multiple and small metastases of the liver and a jejunal metastasis were found, and a palliative total gastrectomy was performed. The surgical specimen revealed a protruding, poorly differentiated medullary adenocarcinoma, with invasion of the submucosal layer. The patient died 4 months after undergoing the laparotomy. This case report is presented to make clinicians aware of the possibility that early gastric cancers may present as brain metastasis.     

A Comparison of Two Simple Measures to Evaluate the Health Status of Asthmatics: The Asthma Bother Profile and the Airways Questionnaire 20

Simple and concise measures for health status are desirable in clinical practice. The Asthma Bother Profile (ABP), which consists of 23 items, has been developed to assess how much asthma bothers patients. The Airways Questionnaire 20 (AQ20) is a simple instrument which consists of 20 items. The purpose of this study was to investigate how the ABP and AQ20 evaluate the health status of patients with asthma. A total of 166 patients with chronic asthma (age: 48 ± 16 yr, 77 males) completed pulmonary function testing, measurement of airway hyperresponsiveness, dyspnea rating, assessments of their anxiety and depression (HADS; Hospital Anxiety and Depression Scale), and assessments of their health status. The health status was assessed using the ABP, AQ20, the short-form 36 health survey questionnaire (SF-36), the Living With Asthma Questionnaire (LWAQ) and the Asthma Quality of Life Questionnaire (AQLQ). The Japanese version of the ABP included only 15 'bother' items out of the original 23 items due to cultural differences. The scores on the ABP were widely distributed, whereas the scores on the AQ20 were skewed towards the milder end of the scale. The ABP had a strong correlation with the Avoidance and Distress constructs on the LWAQ, and Anxiety and Depression on the HADS (Rs = 0.56 ∼ 0.79), and its strongest correlation with the General Health (Rs = - 0.64) scale among the 8 subscales on the SF-36. The AQ20 had a less significant correlation with the LWAQ, AQLQ, and SF-36 than the ABP. The ABP and AQ20 were short and simple to complete, and both measures could easily be used in clinical practice. The ABP can evaluate patients more specifically with respect to distress and bother than the AQ20.
