    Osteoporosis, the most common metabolic skeletal disease, is characterized by decreased bone mass and deteriorated bone quality, leading to increased fracture risk. With the aging of the population, osteoporotic fracture is an important public health issue. Organisms are constantly exposed to various stressful stimuli that affect physiological processes. Recent studies showed that chronic psychological stress is a risk factor for osteoporosis by various signaling pathways. The purpose of this article is to review the recent progress of the association between chronic psychological stress and osteoporosis. Increasing evidence confirms the physiological importance of the central nervous system, especially the hypothalamus, in the regulation of bone metabolism. Both animal and human studies indicate that chronic psychological stress induces a decrease of bone mass and deterioration of bone quality by influencing the hypothalamic-pituitary-adrenocortical (HPA) axis, sympathetic nervous system, and other endocrine, immune factors. Active mastication, proven to be an effective stress-coping behavior, can attenuate stress-induced neuroendocrine responses and ameliorate stress-induced bone loss. Therefore, active mastication may represent a useful approach in preventing and/or treating chronic stress-associated osteoporosis. We also discuss several potential mechanisms involved in the interaction between chronic stress, mastication and osteoporosis. Chronic stress activates the HPA axis and sympathetic nervous system, suppresses the secretion of gonadal hormone and growth hormone, and increases inflammatory cytokines, eventually leading to bone loss by inhibiting bone formation and stimulating bone resorption.

    1-Bromopropane (1-BP) is used in degreasing solvents and spray adhesives. The adverse effects of 1-BP have been reported in human cases and adult animal models, and its developmental toxicity has also been reported, but its effects on developmental neurotoxicity have not been investigated in detail. We evaluated the effects in rat pups of prenatal exposure to 1-BP on behaviors such as scratching and wet dog shakes (WDS), which were induced by injection of kainate (KA). Pregnant Wistar rats were exposed to vaporized 1-BP with 700 ppm from gestation day 1 to day 20 (6 h/day). KA at doses of 0.1, 0.5, and 2.0 mg/kg were intraperitoneally injected into a control group and a 1-BP-exposed group of pups on postnatal day 14. There was no significant difference in scratching between the control and the prenatally 1-BP-exposed groups, while suppression of the occurrence ratio of WDS was observed at the low dose of 0.1 mg/kg of KA in the prenatally 1-BP-exposed pups. Our results suggest that prenatal exposure to 1-BP affects neurobehavioral responses in the juvenile period.

    When crises such as natural disasters or industrial accidents occur in workplaces, not only the workers who are injured, but also those who engage in emergency or recovery work may be exposed to various health hazards. We developed a manual to enable occupational health (OH) experts to prevent health hazards. The manual includes detailed explanations of the characteristics and necessary actions for each need in the list of “OH Needs During Crisis Management” developed after an analysis of eight cases in our previous research. We changed the endings of explanatory sentences so that users could learn how often each need occurred in these eight cases. We evaluated the validity of the manual using two processes: 1) Providing the manual to OH physicians during an industrial accident; 2) Asking crisis management experts to review the manual. We made improvements based on their feedback and completed the manual. The manual includes explanations about 99 OH needs, and users can learn how and what to do for each need during various crisis cases. Because additional OH needs may occur in other crises, it is necessary to collect information about new cases and to improve the comprehensiveness of the manual continuously. It is critical that this crisis management manual be available when a crisis occurs. We need to inform potential users of the manual through various media, as well as by posting it on our website.

    In this paper we consider the significance and mission of medical humanities in medical education from the following six viewpoints: (1) misunderstanding of the medical humanities; (2) its historical development; (3) the criteria for the ideal physician; (4) the contents of current Medical Humanities education; (5) the basic philosophy; and (6) its relation to medical professionalism. Medical humanities consists of the three academic components of bioethics, clinical ethics and medical anthropology, and it is a philosophy and an art which penetrate to the fundamental essence of medicine. The purpose of medical humanities is to develop one’s own humanity and spirituality through medical practice and contemplation by empathizing with patientsʼ illness narratives through spiritual self-awakening and by understanding the mutual healing powers of human relations by way of the realization of primordial life. The basic philosophy is “the coincidence of contraries”. The ultimate mission of medical humanities is to cultivate physicians to educate themselves and have a life-long philosophy of devotion to understanding, through experience, the coincidence of contraries.

    Helicobacter cinaedi is typically isolated from immunocompromised patients. Some reports of infection caused by H.cinaedi have been found in recent years. We experienced three cases of H.cinaedi bacteremia in one year and ten months in our hospital, although the detection of H.cinaedi in blood cultures is extremely rare. In case 1, a 77-year-old female had been treated with a steroid and immunosuppressive agent for interstitial pneumonia. In cases 2 and 3, two 71-year-old men had been treated with chemotherapy for lung cancer. Although the identification of the bacteria could not be performed by the culture method in the three cases, H.cinaedi bacteremia was diagnosed by a 16S rRNA gene sequencing analysis in case 1, and by nested PCR in cases 2 and 3. H.cinaedi bacteremia often tends to recur and also requires prolonged antimicrobial therapy. We believe that gene analysis is useful in the identification of H.cinaedi.

    Neovascular glaucoma is a serious complication associated with retinal ischemic changes, which increase the production of vascular endothelial growth factor. Vascular endothelial growth factor has been implicated as a key molecule in the development of newly formed vessels and neovascular glaucoma. Intravitreal injection of bevacizumab, a full-length humanized anti-vascular endothelial growth factor monoclonal antibody, leads to a dramatic regression of the new iris and iridocorneal angle vessels on slitlamp examination. However, anterior segment angiography reveals that bevacizumab does not cause a regression of the neovascular vessels themselves but reduces vascular permeability while newly formed vessels are still present in the iris and iridocorneal angle. This review focuses on the pathology and diagnosis of neovascula glaucoma and the effect of intravitreal bevacizumab on the iris and iridocorneal angle neovascularization.

    The Department of Nursing of the university revised its curriculum for students admitted in 2012 or later, including the introduction of integrated subjects. With the aim of improving the practical clinical skills of students and integrating knowledge, skills, and techniques, the following integrated subjects: Objective Structured Clinical Examination (OSCE) I held in the first term of the third-year (15 hours as one credit), and OSCE II held in the second term of the fourth year (30 hours as one credit), were adopted, and simulation-based education was introduced. In this report, we summarized our experience of a simulation education system for nursing students in the year 2014 aiming to improve studentsʼ skill of wheelchair transfer of a patient with left hemiplegia and patientʼs living environment. Many positive responses, such as usefulness in future nursing training, were obtained upon the introduction of the simulation education system. Issues to be addressed in the future, including lack of sufficient time to practice and availability of rooms, were also noticed.

    We gathered seven specialists from various fields who are interested in worker injury prevention programs, based on cases of patients who had suffered refractory injuries requiring hand surgery because of industrial accidents. The patients were asked to write their thoughts and ideas on the theme, “Measures that must be implemented to prevent arm injuries.” The content obtained was classified into different categories, using the KJ method, and was scripted to sort out the items. As a result, the following eleven points were identified as measures to prevent serious hand surgery-related injuries: 1. Purchase safe machinery, 2. Create a list of machines that require caution, 3. Enclose a machine’s various rotating parts, 4. Carry out periodic maintenance work on the machines, 5. Indicate dangerous areas by putting up signs that attract attention, 6. Illuminate the rotating parts more brightly and avoid placing objects around them, 7. Systematically carry out safety education that creates a strong impact, 8. Encourage workers to look after their own health, 9. Announce policies on health and safety, 10. Re-examine the operational procedures, and 11. Be prepared in case an accident occurs. A perspective based on the results of this research is deemed important in creating a workplace improvement manual in the future.
