1) 34, 9 and 57% of the 5th year medical students participating in clinical clerkship training program agreed on the need for selecting palliative therapy, death with dignity, and euthanasia, respectively, in response to a terminal stage of malignancy.
2) 60% of medical students supported the organ transplant legislations, but only 23% actually carried an organ donor card. 26% of the surveyed students supported the Japan Society of Obstetrics and Gynecology's attitude towards preimplantation diagnosis.
3) It was pointed out that they had better educated about bioethics.

We evaluated the association between respiratory symptoms and hydration volume during last 1 week of life in terminal cancer patients using retrospective study. The subjects were 138 terminally patients with malignancies. Patients were classified into two groups: the low hydration group (group L, n=85) who received 1,000 ml or less of artificial hydration per day in 1 week before death and high hydration group (group H, n=53) who received over 1,000 ml per day. We compared appearance of dyspnea and bronchial secretion on group L with group H. 64.1% of group H had dyspnea, and 52.8% had bronchial secretion. These fractions are significantly higher than group L (32.9%, 15.3%). In the results of multiple regression analysis, lung involvement (odds ratio: 3.55), hydration over 1,000 ml per day (3.54), and administration of opioid (0.40) were significantly related dyspnea. Lung involvement (7.29), hydration over 1,000 ml per day (4.43), and oral intake (0.31) were significantly related bronchial secretion. Our results provide preliminary evidence that excessive artificial hydration therapies influence the respiratory symptoms in terminal cancer patients. 1,000 ml of hydration may be used as a rough indication in terminal stage.

An 84-year-old man, who had been given a diagnosis of advanced aortoventricular block 2 years previously, underwent implantation of a pacemaker (PM) through the left subclavian vein. However, 7 months later a skin ulcer developed at the implantation site, but without any evidence of bacterial infection. Therefore, a PTFE-covered PM battery was reimplanted at the same site. Three months later, the skin ulcer recurred and he received a third implantation in the right side. However, another skin ulcer with infection developed in the right side. He was then transferred to our hospital for another PM reimplantation. We covered the battery and the entire lead with PTFE, then placed the PM lead directly into the cardiac muscle, and implanted the PM battery below the rectal muscle under general anesthesia. A patch test 4 months later revealed a positive reaction to nickel and silicon. Finally, we diagnosed pacemaker dermatitis. The patient has remained free of skin ulcers for over 1 year.

Background/Aims: Although certain allergic diseases have been reported to be associated with the prevalence of functional dyspepsia (FD) and irritable bowel syndrome (IBS), it is unclear whether the presence of multiple allergic diseases further increases the prevalence of FD and IBS.The aim of this study is to determine this issue in young people. Methods: A cohort of 8923 Japanese university students was enrolled and diagnoses of FD and IBS were confirmed using Rome III criteria.Allergic disorders diagnosed at medical institutions were obtained by means of a self-administered questionnaire. Results: The prevalence of FD, IBS, and their overlap was found to be 1.9%, 6.5%, and 1.1%, respectively. Pollen allergy was independently positively correlated with FD, IBS, and overlap of FD and IBS. Allergic rhinitis was positively linked to IBS. Drug allergy was positively associated with FD. The presence of multiple allergic diseases was positively correlated with FD and IBS (FD: adjusted OR for 2 allergic diseases: 1.95 [95% CI, 1.24-2.98], P for trend = 0.003; and IBS: adjusted OR for 1 allergic disease: 1.40 [95% CI, 1.15-1.69], 2 allergic diseases 1.47 [95% CI, 1.12-1.91], and 3 or more allergic diseases: 2.22 [95% CI, 1.45-3.28], P for trend = 0.001). Additionally, the concomitant existence of multiple allergic diseases was also demonstrated to have a trend that correlated with the overlap of FD and IBS (P for trend = 0.018). Conclusion Allergic disease multimorbidity is positively correlated with the prevalence of FD and IBS in a young population.

Endoscopic submucosal dissection (ESD) is the standard treatment method for esophageal, gastric, and colorectal cancers. However, it has not been standardized for duodenal lesions because of its high complication rates. Recently, minimally invasive and simple methods such as cold snare polypectomy and underwater endoscopic mucosal resection have been utilized more for superficial nonampullary duodenal epithelial tumors (SNADETs). Although the rate of complications associated with duodenal ESD has been gradually decreasing because of technical advancements, performing ESD for all SNADETs is unnecessary. As such, the appropriate treatment plan for SNADETs should be chosen according to the lesion type, patient condition, and endoscopist’s skill.

Background/Aims: Functional dyspepsia (FD) may be a common digestive disease worldwide and reduces the quality of life of patients. However, only a few studies have investigated the association between eating behavior and FD. The purpose of this cross-sectional study is to examine the association between eating behavior and prevalence of FD in a young Japanese cohort. Methods: In this study, we enrolled 8923 Japanese university students. FD is diagnosed based on the Rome III criteria. Eating habits and frequency of meals were investigated using a self-administered questionnaire. Results: The FD subjects had a younger mean age, a lower body mass index, and a lower proportion of men compared to the non-FD subjects.An independent positive association between skipping breakfast and/or lunch and FD was found (adjusted ORs were 1.60 [95% CI, 1.10-2.32] for breakfast and 2.52 [95% CI, 1.04-5.18] for lunch). Skipping dinner, extra meals (snacks) or midnight snacks was not associated with FD. The prevalence of FD in subjects eating 1, 2, and 3 meals per day was 4.8%, 2.2%, and 1.7%, respectively. The frequency of meals was independently inversely associated with prevalence of FD (adjusted ORs were 1 per day: 2.72 [95% CI, 1.19-5.42], and 2 per day: 1.69 [95% CI, 1.16-2.43], P for trend = 0.001). Conclusions In the young Japanese people, the frequency of meals may be independently inversely associated with prevalence of FD. In particular, skipping breakfast and/or lunch was associated with the prevalence of FD.

Background/Aims: Evidence regarding the association between body mass index (BMI) and functional dyspepsia (FD) in the Asian population is limited.Further, no study has evaluated this issue in young people in Asian and Western populations. Thus, we aim to investigate this issueamong young Japanese people. Methods: The study subjects comprised of 8923 Japanese university students. BMI was divided into 4 categories (quartiles) on the basis of thestudy subjects’ distribution (lowest, low, moderate, and high [reference]). The definition of lean, normal, overweight, and obesewas BMI < 18.5 kg/m2 , 18.5 ≤ BMI < 25 kg/m2 (reference), 25 kg/m2 ≤ BMI < 30 kg/m2 , and 30 kg/m2 ≤ BMI, respectively. The definition of FD was based on the Rome III criteria. Results: The prevalence of FD was 1.9% in this cohort. The lowest BMI was independently associated with FD after adjustment (adjusted odds ratio [OR], 2.88; 95% confidence interval [CI], 1.46-3.67); P for trend = 0.001). The lowest BMI was independently associated with FD in women but not in men (OR, 2.94; 95% CI, 1.59-5.77; P for trend = 0.001). Leanness was independently associated with FD in total and in women but not in men (total: adjusted OR, 2.01; 95% CI, 1.40-2.86) and women (OR, 2.19; 95% CI, 1.35-3.45). However,interaction analysis showed no significant difference for sex. Conclusions Among young Japanese people, BMI may be independently inversely associated with FD. Leanness may be an independent associated factor for FD in the young Japanese women.

STUDY DESIGN: A cross-sectional study. PURPOSE: To clarify the prevalence of chronic nonspecific low back pain (CNSLBP) and its associated factors among middle-aged and elderly Japanese individuals using data from a musculoskeletal examination conducted in general Japanese populations. OVERVIEW OF LITERATURE: Most studies evaluating low back pain-associated factors have been conducted in Western countries, but they have not always evaluated CNSLBP. METHODS: We obtained data on 213 subjects aged >50 years who responded to a survey regarding age, gender, body mass index, lifestyle-related diseases (diabetes mellitus, hypertension, and hyperlipidemia), glucocorticoid use, smoking and alcohol-drinking habits, labor intensity, and chronic low back pain (CLBP) and underwent screening for lumbar spinal stenosis, evaluation for quality of life (QOL), and evaluation for specific spinal pathology via thoracolumbar spine X-rays. We investigated the prevalence of CNSLBP and association between CNSLBP and measured variables. RESULTS: The prevalence of CNSLBP and chronic specific low back pain (CSLBP) was 15.4% and 9.3%, respectively. Among the subjects with CLBP, 62.2% had CNSLBP. In age-adjusted logistic models, smoking habits (p=0.049, odds ratio [OR]=2.594), low back pain (p < 0.001, OR=0.974), lumbar function (p=0.001, OR=0.967), and social function (p=0.023, OR=0.976) in the Japanese Orthopaedic Association Back Pain Evaluation Questionnaire (JOABPEQ) were significantly associated with CNSLBP, whereas EQ-5D utility score (p=0.024, OR=0.068), low back pain (p=0.007, OR=0.981), lumbar function (p=0.001, OR=0.963), walking ability (p=0.001, OR=0.968), and social function (p=0.002, OR=0.966) in JOABPEQ were significantly associated with CSLBP. CONCLUSIONS: CNSLBP among middle-aged and elderly individuals was associated with smoking habits and decreased QOL; however, CSLBP was considered to be more multilaterally associated decreased QOL.

STUDY DESIGN: Cross-sectional study. PURPOSE: The purpose of this study was to evaluate the correlation between pelvic tilt (PT) and the sacro-femoral-pubic (SFP) angle, which is easier to identify than PT, in middle-aged and elderly Asian subjects from the general population. OVERVIEW OF LITERATURE: Measuring PT is important in the diagnosis and treatment of adult spinal deformity. However, identifying femoral heads, which are necessary to determine PT, using sagittal radiographs is often difficult. METHODS: Standing coronal and sagittal pelvic radiographs of individuals aged more than 50 years were taken during a local medical examination. The subjects were divided into female, male, and total groups at the time of evaluation. Linear regression analysis was performed to investigate the relationship between PT and the SFP angle, which were obtained from the X-rays. RESULTS: The present study included 291 subjects. There were no statistically significant differences between the left and right SFP angles, and there was gender difference regarding the SFP angle. However, a gender difference was observed regarding PT. The correlation between PT and the SFP angle was substantiated in each group. Pearson's correlation coefficients between PT and the SFP angle in the total, female, and male groups were 0.696, 0.853, and 0.619, respectively. In the linear regression analysis, PT was calculated as follows: PT=60.1−0.77×(SFP angle) in the total group, PT=62.8−0.80×(SFP angle) in the female group, and PT=51.5−0.64×(SFP angle) in the male group. CONCLUSIONS: A significant correlation between PT and the SFP angle was observed in middle-aged and elderly Asian subjects from the general population.
