    The state of radiofrequency ablation for the treatment of hepatocellular carcinoma in Japan's Chugoku-Shikoku district was assessed by a questionnaire completed by 18 participating hospitals. Inclusion criteria of the therapy and the methods of evaluating ablated areas were similar among the 18 hospitals. However, large differences were observed in some questionnaires, in matters such as ablation protocols. These factors may need to be standardized.

    PURPOSE: Circumscribed choroidal hemangioma is an uncommon, benign vascular tumor that typically appears in the posterior pole of the eye. Visual acuity loss typically results from its exudation, followed by serous retinal detachment. The purpose of the study was to evaluate the efficacy and the safety of external beam irradiation in treating circumscribed choroidal hemangioma. METHODS: We treated 4 eyes of 4 patients with circumscribed choroidal hemangioma with external beam irradiation at Okayama University Hospital from 2002 to 2009. A total absorbed dose of 20 Gy (beam energy, 4, 10 MV) was applied to each of the 4 patients. Each patient received a single 2-Gy daily fraction for five consecutive days in a week, for two consecutive weeks. RESULTS: In all cases, the retinal detachment showed complete resolution within 8 to 48 days after treatment. A decrease in tumor thickness was observed in all cases except one in which the follow-up period was rather short (3.7 months). The visual acuity improved in all 4 eyes. No eyes showed deterioration of visual acuity. During follow-up periods of 3.7 months to 58.5 months, there were no signs of radiation-induced cataract, retinopathy or optic neuropathy.

    To evaluate the usefulness of the waterless hand washing method for surgical anti-sepsis, we conducted a microbial sampling study, comparing it to a conventional surgical scrub method. A total of 18 operating-room nurses were undertaking the following three-hand washing protocols : scrubbing with blushes using 4w/v% chlorhexidine gluconate (CHG) and also rubbing with CHG, followed by application of a 0.2w/v% CHG with ethanol (HS) preparation. (conventional method); rubbing with CHG and application of HS (two-stage surgical scrub method; TSS); rubbing with anti-septic soap and application of HS (waterless method; WL). Microbial sampling was conducted after hand washing using the glove juice method. No statistically significant differences in bacterial numbers were found among these three methods. The number of bacterially positive subjects was significantly higher in the conventional method than the TSS method. These results indicate that there are adverse effects of blush-scrubbing, as the detected bacteria were related to normal skin flora. As such, the WL method for hand anti-sepsis appears to be equivalent to the conventional surgical scrubbing method in terms of microbial detection. The WL method should therefore be introduced as a standard hand anti-sepsis method at the time of surgery because it is cost-effective as well as time-efficient.

    A 77-year-old woman was admitted to our hospital due to abdominal pain and body weight loss. A palpable mass the size of an infant's head was tender on palpation and identified as an epigastric lesion. Colonoscopic examination revealed stenosis of the transverse colon, although no intraluminal growth of the tumor was found. The histologic findings of the biopsy material were poorly differentiated and/or undifferentiated cells. Abdominal CT scan showed an irregular-shaped tumor with a diameter of 10cm invading the stomach and jejunum. We performed an operation under a diagnosis of extramurally growing cancer or malignant lymphoma of the colon. Partial resection of the transverse colon was done by distal gastrectomy and partial resection of the jejunum. Histologic examination of the operative specimens revealed moderately differentiated adenocarcinoma of the transverse colon, prominently proliferating into the surrounding tissues. The finding of a long stenotic lesion and extramural compression by colonography are characteristic of this tumor, based on a review of 43 literature reports in Japan.
