Few studies have examined medical students' perceptions of community medicine and specialty choice through comparison between students of quotas related to community medicine and regular admission. We conducted a questionnaire survey on students' desire for future work places, types of health facility/hospital, medical specialization, and community medicine involving year 1 to year 5 students in Gifu University School of Medicine (n=335, selective admission: regular admission=81:254) . This study demonstrated that the selected students for community medicine (years 1 to 5) preferred to work at a core/small-sized hospital in a rural area and tended to choose the specialties that were characterized by primary care, such as pediatrics. Moreover, they had positive perceptions of community medicine. Further follow-up study needs to be undertaken in order to explore how students are actually engaging in community medicine after graduation.

Background : The effects of rehabilitation on hemodialysis patients are unknown. We assessed the effects and investigated the association between rehabilitation treatment effects and all-cause mortality. Methods : This prospective cohort study included 120 patients on maintenance hemodialysis. ADL was assessed using the Functional Independence Measure (FIM) score (total points, 126), which comprises 13 motor items (total points, 91) and five cognitive items (total points, 35). A survival curve was constructed using the Kaplan-Meier analysis and stratified into an increase or no-increase of the FIM score. Multivariable logistic regression analysis was used to determine factors associated with the effects of rehabilitation. Discriminative sensitivity of FIM cognitive items for an increase in total FIM was estimated using the area under the receiver operating characteristic (AuROC) curve. Results : The average total FIM score increased from 64.2±3.6 to 75.8±3.0, and the increase in FIM motor and cognitive items was 11.0±1.3 and 0.5±0.6, respectively. The cumulative survival rate within 2.5 years was significantly higher in the FIM increase group than that in the FIM no-increase group. FIM cognitive items and anemia were significantly associated with rehabilitation effects, and AuROC showed that a cutoff of 34 points in cognitive FIM had moderate discriminative sensitivity for a total FIM increase (AuC, 0.719 ; p<0.0008). Conclusions : Rehabilitating hemodialysis patients improved their FIM score (particularly the motor items), and a higher FIM score resulted in a better prognosis. The effectiveness of rehabilitation depends on maintaining a perfect FIM cognitive score.

Vertebral fractures occur with only slight trauma in patients with diffuse idiopathic skeletal hyperostosis (DISH). However, a lumbar vertebra fracture, due to an intraoperative body position has not been previously reported. An 87-year-old woman with kyphosis sustained a left trochanteric fracture of her femur. The patient was placed in a supine position during the operation. Postoperatively, the patient experienced severe right thigh pain. Magnetic resonance imaging revealed an L4 vertebral fracture. Computed tomography revealed ankylosis from the upper thoracic spine to the sacrum. While in a supine position under general anesthesia, the contact of the patient's lower back with operating table likely created a fulcrum at her lumbosacral spine acting as a long lever arm, bearing the mass of her upper body. We performed L1-S2 posterior stabilization. DISH patients with kyphosis placed in a supine position have an increased risk for lumbar vertebral fracture.

In this study, we aim to compare the criteria for sensitizers among national organizations in various countries and international organizations, and to specify whether each Pollutant Release and Transfer Register (PRTR)-designated chemical substance is a sensitizer by each organization. The definition of sensitizing chemicals and the designation of respective sensitizers according to the PRTR law, Japan Society for Occupational Health (JSOH), American Conference of Governmental Industrial Hygienists (ACGIH), European Union (EU), and Deutsche Forschungsgemeinshaft (DFG) were studied. Of the 435 PRTR-designated chemical substances, 15 are listed as sensitizers according to the PRTR law, 16 as sensitizers of the airway and 21 as sensitizers of the skin by JSOH, 12 as sensitizers (no discrimination) by ACGIH, 19 (airway) and 85 (skin) by EU, and 15 (airway) and 43 (skin) by DFG. Only 9 substances were designated as sensitizers by all these organizations. The variation in the designation of sensitizers is accounted for by the differences in the classification criteria and grouping of chemical substances. JSOH limits the definition of sensitizers to substances that induce allergic reactions in humans and uses only human data. Other organizations utilize not only human evidence but also appropriate animal tests. In addition, EU designates an isocyanate as a sensitizer except those for which there is evidence showing that they do not cause respiratory sensitivity. The worldwide enforcement of the globally harmonized system (GHS) of classification and labeling of chemicals could promote not only the consistent designation of sensitizers among national and international organizations, but also the development of testing guidelines and classification criteria for mixtures.

Wide-awake local anesthesia has many advantages. We describe a new method to use wide-awake local anesthesia with more flexibility. A 32-year-old man with a severe right-hand contracture after an iatrogenic tourniquet accident during an anterolateral thigh flap for a partial hand amputation underwent contracture release using external fixation after proximal row carpectomy and subsequent tenolysis. We performed most of the tenolysis procedure under general anesthesia and the final stage with an intraoperative assessment of active finger movement and dissection under local anesthesia. He regained his grip strength 2.5 years post-injury. General anesthesia is useful to treat a surgical site with extensive hard scars, whereas local anesthesia is useful for adjusting tension in an awake patient. The indication for wide-awake surgery is yet to be established; our method of combining general and local anesthesia in the tenolysis procedure illustrates the possibilities in expanding this method.

A 2-month-old male infant was transferred to our hospital for suspected cardiomyopathy because he had livedo reticularis and peripheral coldness. An electrocardiogram showed ischemic change and an echocardiogram showed a dilated, poorly functioning left ventricle. Therefore, we performed urgent cardiac catheterization. The coronary artery was not visualized by aortography, but the single coronary artery arising from the pulmonary artery was depicted by pulmonary angiography. Therefore, we performed emergent surgery. The whole coronary arteries traveled directly inferiorly from the left side of the pulmonary trunk. A patent ductus arteriosus (PDA) was closed at the operation. We established cardiopulmonary bypass using two arterial cannulae through both ascending aortas and pulmonary trunk to maintain coronary blood flow. Direct implantation is difficult because the coronary ostium is far from the ascending aorta. Therefore, we chose to perform the Takeuchi procedure using an intrapulmonary artery tunnel. The patient's postoperative course was good, and he was discharged on postoperative day 22. A case of an anomalous origin of a single coronary artery from the pulmonary artery without any other heart disease is extremely rare. Management of cardiopulmonary bypass and myocardial protection in this abnormality is discussed.
