Recently, allogeneic bone marrow transplantation (allo-BMT) has been established for the treatment of hematological disorders. Fifteen patients had recieved allo-BMT at Tsuchiura Kyodo General Hospital as of April 1999. In this paper, we analyzedthe results and the problems of allo-BMT at our institution. The mean age of patients was 29.2years. Seven patients had AML, 5 ALL, 1 CML, 1 non-Hodgkin's lymphoma and one had severe aplastic anemia. Bone marrow donors were all HLA-identical siblings. Most of the patients were conditioned with a combination of busulfan or totalbody irradiation, cyclophosphamide and etoposide. To prevent GVHD, cyclosporine A and methotrexate were mainly used. Patients with acute GVHD were 4 and patients with chronic GVHD were only two. Three grade I patients with acute GVHD and all with chronic GVHD did not require therapy. In spite of small numbers of transfused cells, no cases of transplant rejection were found. All these engrafted patients achieved a WBC≥1×103μl after a median of 19.5days and a Plt≥5×104/μEl after a median of 38.1days. Five of the 14 engrafted patient relapsed in a median of 6.7months and all died in a median of 9.6months. Eight are alive in complete remission for 0.2 to 39.4 months (median 21.7months). For the improvement of the disease-free survival rate after allo-BMT, the prevention of relapse and prophylaxis of GVHD and infection are important. At our institution, especially the former is important. The conditioning regimens were stronger than usual but acute and chronic GVHD was very mild, therefore GVL would be weak. If prophylaxis of GVHD is weaken and mild GVHD ans GVL occur frequently, relapse will be prevented and better results will be obtained.

We reviewed 632 cases which had undergone ultrasonograpy for thyroid disorders.(1) The sonographic examination found nodular lesions in 157 cases (including 52 solid tumor cases) and diffuse enlargement in 38 cases. No abnormalities were found in the remaining437 cases.(2) Further examination revealed that the cases of nodular lesions included 7 thyroid cancer cases (6 papillary carcinomas and 1 follicular carcinoma), 2 cases of hyperthyroidism, and 3 cases of hypothyroidism.(3) Diffuse enlargement cases included 5 cases of overactive thyroid (1 subacute thyroiditis and 5 Graves' diseases), 2 cases of underactive thyroid (chronic thyroiditis). Assays for antithyroid autoantibodies showed positive results even in the 31 cases of normal thyroid function.(4) Four in 7 cases diagnosed as thyroid cancer and 5 in 12 cases diagnosed as thyroid dysfunction (4 of 5 cases were elderly people 60 years of age or over) were screened by ultrasonography.
We concluded that ultrasonography is a valuable diagnostic procedure for early detection of not only thyroid malignancies but also disordered thyroid function. Abdominal sonography is often used for screening. The use of ultrasound for the thyroid gland is recommended as a standard procedure in the regular health screening program.

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.

The results of pulmonary function tests (PFTs) given to those inhabitants in the western part of Kanagawa Prefecture who visited our hospital for medical examinations between April 1991 and March 1992 were studied comparatively, with their occupation, age, sex, environmental factors and smoking habits taken into account. For this purpose, the subjects totaling 1, 322 were classified into three groups-those who live in the hilly area, those who live in the suburban area and those who live in the coastal area. In the present study, the results of the four PFT items-FVC, FEV 1.0%, FVC and FEV 1.0%-were checked. Careful examination brought into relief the startling fact that many aged people, non-farmers and nonsmokers in the suburban subject group have impaired pulmonary function. It is said that because of the Tokyo-Nagoya expressway and many other motorways, the air in the suburban area is fouled up with exhaust gas to a greater extent than in the other two areas. Although our finding alone could not identify the cause of impaired pulmonary function definitely, air pollution was thought to be a culprit. Further investigation should be made into the living conditions of the examinees. Moreover, environmental monitoring and data analysis have to be carried out in the future.

We describe a case of Inose-type hepatic encephalopathy due to congenital gastro-renal shunt that was effectively treated with balloon-occluded retrograde transvenous obliteration (B-RTO). An 80-year-old woman repeatedly experienced syncope. Her plasma concentration of NH3 was elevated to 2363 level and syncope attacks improved after the gastro-renal shunt was closed by B-RTO. Although a congenital gastro-renal shunt is usually treated by surgical ligation, B-RTO is can be effective and less invasive treatment for such cases.

Purpose:
Twenty five years have passed since the first national survey on erectile dysfunction (ED) in Japan. The Japanese Society for Sexual Medicine conducted a nationwide survey on the actual status of sexual function targeting men over 20 years old in Japan using validated questionnaires commonly used in clinical practice.
Materials and Methods:
Japanese men aged 20 to 79 years participated in our online epidemiological study on sexual dysfunction. Erectile status was assessed by direct questioning and specific questionnaires. Risk factors and frequencies of sexual intercourse, masturbation, nocturnal erections, and feeling sexual desire were assessed. The prevalence of these risk factors was compared between men with and without ED. Prevalence and frequencies were calculated for each 5-year age group. Main outcomes were the prevalence and number of patients with ED and simultaneous evaluation of age-related variations.
Results:
Direct questioning of the men revealed that 13.0% felt troubled by ED. Although 81.0% of them had at least some ED symptoms based on a Sexual Health Inventory For Men score of ≤21, the prevalence of men with ED by Erection Hardness Score (EHS), the most appropriate questionnaire for Japanese with low sexual activity, was 30.9%, indicating that 14,012,596 men have ED. Most risk factors were related with ED, whereas frequencies of sexual intercourse, masturbation, nocturnal erections, and feeling sexual desire were affected by aging. However, the low frequency of these factors in the young generation was surprising.
Conclusions
The EHS-based assessment revealed a prevalence of ED of 30.9%, which affected approximately 14 million men, and that the sexual desire, erection stiffness, orgasms, and satisfaction were lower than expected in young Japanese men, especially those aged 20 to 24 years, although those factors tended to worsen with aging. We believe that these findings actually reveal the current sexual status of men in Japan.
