To examine the universal validity of results in preceding reports on hepatitis B antigen among inhabitants of Yachiho village, 4015 farmers in Nagano were investigated. Hepatitis B antigen were detected for 24 persons with single radial immunodiffusion method. The incidence of 0.6 per cent with the insensitive method was compatible with 1.3 per cent in the village with immune adherence hemagglutination method. The prefecture was devided into four areas. The areas where hepatitis B antigen was prevalent persons with elevated transaminase value were frequent.

Laparoscopic gastrectomy has been widely accepted especially in patients with early-stage gastric cancer. However, the safety and oncologic validity of laparoscopic gastrectomy for advanced gastric cancer are still being debated. Since the late 90s', we have been engaged in developing a stable and robust methodology of laparoscopic radical gastrectomy for advanced gastric cancer, and have established laparoscopic distinctive technique for suprapancreatic lymph node dissection, namely the outermost layer-oriented medial approach. In this article, We present the development history of this method, and current status and future perspectives of laparoscopic gastrectomy for advanced gastric cancer based on our experience and a review of the literature.

Many of the students belonging to the School of Health and Social Services will be responsible for health education in the future, and it is important that they have an understanding of the importance of Kampo medicine and the ability to give appropriate guidance in the field. But their educational goals need discussing. We conducted lectures on Kampo medicine with medical school students towards this end, and conducted before and after questionnaire surveys to gauge their effect. Students with a desirable degree of awareness toward Kampo medicine in Japanese society increased from 58.0 ± 15.4% to 88.5 ± 10.2%, and students judging Kampo as either useful or extremely useful rose from 58.4% to 95.9%. It is our hope that, with the raised awareness from these lectures as a base, these students will go on to engage in suitable medical educational activities in the future.

The preparation for influenza pandemic has become very important. However, no standardized educational package against pandemics has been established to date. We developed a simulation–based education drill for Japanese medical students based on the package developed by U.S. medical school. The drill was adapted to 201 medical students, and was evaluated by self–administered questionnaires.
1)More than 90% of the students indicated that the use of this drill is appropriate to experience a simulated pandemic situation, and to learn skills and attitudes such as teamwork and communication.
2)Up to 65% of the students answered they learned a "very clear image" for the "Importance of working as a team with other professionals".
3)The results suggest that this simulation–based education drill make the students aware not only of the need for the preparation for pandemic but also the importance of team–based approach.

BACKGROUND: Dexmedetomidine is a highly selective central α₂-agonist used as a sedative in pediatric intensive care unit (PICU). However, little is known about the relationship between dexmedetomidine dose and its plasma concentration during long-term infusion. We have previously demonstrated that the sedative plasma dexmedetomidine concentration is moderately correlated with the administered dose in adults (r = 0.653, P = 0.001). We hypothesized that there would be a similar relationship between the sedative dexmedetomidine concentration and administered dose in infants. METHODS: All patients admitted to the PICU at Nagoya City University Hospital, Japan, between November 2012 and March 2013 were eligible for inclusion in the study. Plasma dexmedetomidine concentration was measured by ultra-performance liquid chromatography coupled with tandem mass spectrometry. RESULTS: We measured the plasma dexmedetomidine concentration in 203 samples from 45 patients. Of these, 96 samples collected from 27 patients < 2 years old were included in this study. All patients received dexmedetomidine at 0.12–1.40 µg/kg/h. The median administration duration was 87.6 hours (range: 6–540 hours). Plasma dexmedetomidine concentration ranged from 0.07 to 3.17 ng/ml. Plasma dexmedetomidine concentration was not correlated with the administered dose (r = 0.273, P = 0.007). The approximate linear equation was y = 0.690x + 0.423. CONCLUSIONS: In infants, plasma dexmedetomidine concentration did not exhibit any correlation with administered dose, which is not a reliable means of obtaining optimal plasma concentration.

In this report, we describe a case involving a 34-year-old woman who showed good treatment outcomes with long-term stability after multidisciplinary treatment for unilateral cleft lip and palate (CLP), maxillary hypoplasia, severe maxillary arch constriction, severe occlusal collapse, and gingival recession. A comprehensive treatment approach was developed with maximum consideration of strong scar constriction and gingival recession; it included minimum maxillary arch expansion, maxillary advancement by distraction osteogenesis using an internal distraction device, and mandibular setback using sagittal split ramus osteotomy. Her post-treatment records demonstrated a balanced facial profile and occlusion with improved facial symmetry. The patient's profile was dramatically improved, with reduced upper lip retrusion and lower lip protrusion as a result of the maxillary advancement and mandibular setback, respectively. Although gingival recession showed a slight increase, tooth mobility was within the normal physiological range. No tooth hyperesthesia was observed after treatment. There was negligible osseous relapse, and the occlusion remained stable after 5 years of post-treatment retention. Our findings suggest that such multidisciplinary approaches for the treatment of CLP with gingival recession and occlusal collapse help in improving occlusion and facial esthetics without the need for prostheses such as dental implants or bridges; in addition, the results show long-term post-treatment stability.

Objective: The aim of this study is to elaborate on the nutritional intervention in a multimodal intervention (the NEXTAC-ONE program) for the elderly with advanced cancer and to evaluate its tolerability Methods: We prospectively recruited patients aged ≥70 years scheduled to receive first-line chemotherapy for advanced pancreatic or non-small-cell lung cancer. Three nutritional intervention were planned in 8-week study period. The nutritional counseling consists of standard nutritional advice, evaluation and support for nutrition impact symptom, and evaluation and support for eating-related distress and food environment problems. We also provide the oral nutritional supplements rich in Branched Chain Amino Acids (BCAA). Results: 29 patients (96%) of a total of 30 study registrants participated in all three nutrition interventions. Median proportion of days in which patients recorded a nutritional diary was 90%. Median consumption of supplements was 99 %. There was no adverse event associated with nutritional intervention. Conclusions: Our nutritional intervention program showed an excellent compliance in the elderly with advanced cancer patients, and our data indicated a potential protective effect on nutritional deterioration.
