To evaluate the educational effects of a lung-sound auscultation simulator, “Mr. Lung”, we compared outcomes of fifth-year medical students in 2001 and 2002. From June 2001 through March 2002, we used “Mr. Lung” for small-group teaching for 100 fifth-year medical students. The following year, we opened our laboratory so that the fifth-year students could study with “Mr. Lung” by themselves for 1 month. “Mr. Lung” was then used for objective structured clinical examinations in May 2002. From June 2002 through April 2003, we used “Mr. Lung” again for small-group teaching for 91 fifth-year students. The class consisted of 90 minutes' training for the auscultation of lung sounds. At the beginning of class, auscultation tests were performed in which the students listened through their stethoscopes to 3 examples of abnormal lung sounds on “Mr. Lung” and answered questions about the location and quality of the sounds. The percentages of correct answers in 2001 and 2002, respectively, were 36.9% and 35.4% for differences between bilateral lung sounds, 52.5% and 55.8% for coarse crackles, 34.1% and 58.3%(p<0.05) for fine crackles, 69.2% and 70.8% for wheezes, 62.1% and 90.7%(p<0.01) for rhonchi, and 22.2% and 32.6% for stridor. In conclusion, 1 month's self-study with “Mr. Lung” to prepare for the objective structured clinical examinations improves auscultation skills.

The main pathogenic mechanism of diabetes consists of an increase in insulin resistance and a decrease in insulin secretion from pancreatic β-cells. The number of diabetic patients has been increasing dramatically worldwide, especially in Asian people whose capacity for insulin secretion is inherently lower than that of other ethnic populations. Causally, changes of environmental factors in addition to intrinsic genetic factors have been considered to have an influence on the increased prevalence of diabetes. Particular focus has been placed on “gene-environment interactions” in the development of a reduced pancreatic β-cell mass, as well as type 1 and type 2 diabetes mellitus. Changes in the intrauterine environment, such as intrauterine growth restriction, contribute to alterations of gene expression in pancreatic β-cells, ultimately resulting in the development of pancreatic β-cell failure and diabetes. As a molecular mechanism underlying the effect of the intrauterine environment, epigenetic modifications have been widely investigated. The association of diabetes susceptibility genes or dietary habits with gene-environment interactions has been reported. In this review, we provide an overview of the role of gene-environment interactions in pancreatic β-cell failure as revealed by previous reports and data from experiments.

OBJECTIVE: The pharmacological effects of generic (GE) donepezil are the same as Aricept, its brand-name counterpart. However, little is known as to whether these two drugs provide the same quality of life (QOL). The study subjects were patients with Alzheimer's disease who were taking donepezil hydrochloride tablets, and were selected by visiting either the local pharmacies or the patients' homes. We chose the brand-name drug Aricept and its GE form donepezil to investigate, from a long-term caregiver's perspective, the influence of both drugs on the patients' QOL. METHODS: An EuroQol-5 Dimension (EQ-5D) was used to assess the QOL of patients with Alzheimer's disease, before and after various Aricept and/or donepezil regimens. Patients were divided into four groups: first time users of Aricept (n=43), first time users of GE donepezil (n=45), users refilling previous prescriptions of Aricept (n=51), and users switching from Aricept to GE donepezil (n=51). RESULTS: The average change in the EQ-5D utility indices rose significantly in the patients starting a new regimen of Aricept and its GE drug. The patients continuing an existing regimen of Aricept showed no significant differences, even after Aricept was switched to a GE drug. CONCLUSION: The QOL of patients starting a new regimen of Aricept and its GE drug improved. The QOL was maintained upon switching to the GE drug form.

PURPOSE: To analyze unusual events and focus discussion on pulmonary metastasis in particular after low-dose-rate brachytherapy (LDR-BT) for prostate cancer (PCa). MATERIALS AND METHODS: A total of 616 consecutive patients who had undergone LDR-BT for clinically localized PCa at Jikei University Hospital between October 2003 and April 2010 were enrolled in this study. Follow-up information was summarized, and patterns of biochemical recurrence and clinical outcome were investigated. RESULTS: Disease risk was stratified as low-risk in 231 patients, intermediate-risk in 365, and high-risk in 20, respectively. Of these patients, 269 (43.7%) had received hormonal therapy (HT) in combination with LDR-BT, and 80 (13.0%) had received external beam radiotherapy (EBRT). Average dosimetric parameter values with and without EBRT were 95.3% and 94.2% for V100, 132.8 Gy and 164.2 Gy for D90, and 180.6 Gy2 and 173.7 Gy2 for the biologically effective dose. Biochemical recurrence was noted in 14 patients (6.1%) in the low-risk group, 25 patients (6.8%) in the intermediate-risk group, and 6 patients (30.0%) in the high-risk group, respectively. In these cases of biochemical recurrence, 9 (64.3%), 13 (52.0%), and 4 patients (66.7%) in each respective risk group showed signs of clinical recurrence. Five patients (19.2%) with clinical recurrence developed pulmonary metastases, of which 4 were isolated lesions. All tumors responded favorably to subsequent HT. CONCLUSIONS: LDR-BT for biologically aggressive PCa may be linked to possible pulmonary metastasis owing to tumor dissemination during seed implantation. This information is important in planning adequate treatment for these patients.

Objective: Soon after two massive earthquakes in Kumamoto, Japan, on April 14 and 16, 2016, the Shirakawasuigen pharmacy located in the Minamiaso village received prescriptions for disaster medications. Since prescriptions for disaster medications are typically used at temporary emergency shelters, pharmacies usually do not receive requests for them. On checking the content of these prescriptions, we found numerous prescription errors and queries. This study aimed to assess issues with dispensing medications after disasters.Methods: We reviewed all disaster medication prescriptions received by the pharmacy from April 20 to May 28, 2016 and the medication histories of these patients. We confirmed each patient’s data and medical and medication histories. Furthermore, we classified disaster prescription errors and queries into five categories according to their content and summed them in each category.Results: We obtained patients’ medical and medication histories from 100 (77.5%) of the 129 prescriptions received. Of the 129 prescriptions, a total of 158 prescription errors and queries pertaining to 96 (74.4%) prescriptions were confirmed: 88 (55.7%) for unclear medication usage and dosages, 22 (13.9%) for incorrect medication names, 34 (21.5%) for pharmaceutical queries, 8 (5.1%) for exceeding fixed prescription days (within seven days), and 6 (3.8%) for other issues.Conclusion: Nearly 80% of the prescriptions for disaster medications had prescription errors and queries. Therefore, we evaluated that the prescription’s format and entry method can be improved. Furthermore, to ensure a smooth drug supply and to reduce prescription entry deficiencies and formal prescription queries, pharmacists need to effectively manage disaster prescriptions.
