1) We compiled lists of accredited training hospitals for postgraduate education from the matching program list and of hospitals that employ board-certified specialists in emergency medicine.We then evaluated the number of training hospitals that employ board-certified specialists.
2) There are 1072 accredited hospitals for postgraduate education. However, only 546 (50.8%) of these hospitals employ board-certified specialists in emergency medicine.
3) Accredited training hospitals with emergency-medicine specialists are prevalent in Okinawa, Tokushima, and Kagawa prefectures.However, the prevalence of these hospitals is surprisingly low in metropolitan areas.

Qualitative research has gained greater attention in medical research, but it might seem to be unscientific because qualitative and quantitative research methods are grounded in different paradigm.
In this article, we introduce three major qualitative research methods frequently used in studies of patient-doctor communications: 1) in-depth interviews; 2) focus group interviews and, 3) semi-structured interviews.
Each qualitative research method has different or common advantages and disadvantages, and which methods should be used depends on the study objectives. Qualitative research and quantitative research are complementary: while quantitative research explains the prevalence or variation of an issue, qualitative research explains the reasons or processes of that prevalence or variation. Combination of the two methods enables the gathering of more comprehensive and explanatory results.

A 76-years-old woman was admitted with a left ventricular tumor that was accidentally found by a transthoracic echocardiogram. The tumor was located in the papillary muscle near the apex, had an irregular surface, and was well mobile. The urgent operation was planned because the tumor might have caused of embolism. A cardiopulmonary bypass was established with distal ascending aortic cannulation and bicaval venous cannulations. The resection of the tumor was performed by a transaortic approach. Pathological examination confirmed the tumor as primary papillary fibroelastoma. During the operation, a thoracoscope was used to assist the resection of the tumor. It was useful for a good visualization in the left ventricle. In this case report we describe a rare case of primary papillary fibroelastoma in the left ventricle and a technique of resection using a transaortic approach with an assistance of a thoracoscope.

In the medical interview portion of the objective structured clinical examination (OSCE), we usually use both detailed checklists and a global rating scale to evaluate a student's performance. In the present study we investigated a problem with the detailed checklists.
1) The quality of the assessment of information-gathering capability was investigated in a station for the medical interview in a pharmaceutical OSCE.
2)A video review revealed a 7% error in the detailed checklist assessment at the OSCE station.
3) Following the interview in this study, the students wrote down the information they had gathered. These results differed by 15.6% from those of the detailed checklist assessment at the OSCE station.
4) In the present style of OSCE, the detailed checklist assessment at the OSCE station is problematic. The style in which the students write down the gathered information after the interview might be re-considered.

We began gastric mass survey at our hospital in May, 1980. During 3 years and 8 months since then, (May, 1980-December, 1983) we performed screening examinations to 16, 341 people by indirect radiography, and checked 2, 824 cases (17.3%) for thorough examination. Among these cases, 2, 083 (73.8%) received endoscopic examination actually, and 55 cases of gastric cancer were discovered. The discovery rate of gastric cancer was 0.336 per cent.
35 cases of these 55 gastric cancer were operated in the surgical department of our hospital. 34 cases were resected (rate of resection was 97.1%) and 33 cases were resected curatively (rate of curative resection was 94.3%). These results were better than that of gastric cancer cases from out-patient clinic of the same period. The results of cases from out-patient clinic of our hospital were: total number of cases 321, resected cases 254 (79.1%), curative resection 189 cases (58.9%), respectively.

During the eleven years from January 1978 to December 1988, we experienced 1, 287 cases of gastric cancer, hospitalized in the surgical department of Tsuchiura Kyodo Hospital which is located in the southern agricultural district of Ibaraki Prefecture.
Among these 1, 287 cases, 1, 233 patients were operated on. Gastric resection was performed in 1, 059 cases including 337 cases of total gastrectomy with the resection rate of 85.9 percent (1, 059/1, 233). In 863 cases, resection gave histologically satisfactory results, and our curative resection rate was 70.0 percent (863/1, 233). Direct mortality rate was 2.35% in all operated cases and 1.32% in resected cases.
The five-year survival rate over the period from 1978 to 1983 was 57.7% in all resected cases and 69.3% in curatively resected cases.
Annual follow up observation showed increases in resection rate, curative resection rate, and five-year survival rate. However, there were no remarkable changes in the rate of total gastrectomy, rate of combined resection of other organs, and degree of lymph nodes dissection.
The main factor contributing to the improvement in the results of surgical treatment of gastric cancer was the increase in the detection rate of cancer in relatively early stages, through gastric mass survey or total check-up in the asymptomatic stage.
