Videotape feedback reportedly improves communication skills in students learning to conduct medical interviews. We carried out a study of videotape feedback in the undergraduate training program of the department of neuropsychiatry. To evaluate the interviews, we used objective structured clinical examinations and feedback from interviewed patients. The students showed several shortcomings, such as passive investigation into symptoms, past history, family history and explanatory models; poorly expressed empathy; unclear summation; poor explanation about what interviewees should do after the interview; and infrequent use of specific probes and silence skills. Feedback from patients was more favorable than that from instructors. Because our program asking psychiatric patients to participate as interviewees seems to have both advantages and disadvantages, using simulated patients would be helpful for examining the validity of our program.

The changes of hemodynamics during bathing in patients with heart diseases were studied by invasive methods using a Swan-Ganz catheter and UCG. As a population, we have used 37 peatients with heart disease, ages 20 to 76 (average age 52.9). There were 26 cases of myocardial infarction, 5 cases of valvular disease, 5 cases of cardiomyo pathy, and 1 case of VSD. Bathing was done with tap water in a Hubbard tank, for 10 minutes at 40°C and for 5 minutes at 43°C in a supine position. Arterial pressure, heart rate, pulmonary arterial pressure, pulmonary wedge pressure, right atrial pressure, cardiac output, stroke volume and stroke work index were increased during bathing and decreased after bathing. Systemic vascular resistance and pulmonary arteriolar resistance were decreased during bathing. Their changes were marked with a bath of 40 to 43°C. These findings suggest that preload may be increased during bathing, and preload and afterload reduced after bathing. Hydrostatic pressure, autonomic nervous reflexes or endocrine system were thought of as possible reasons for the increase in pulmonary arterial pressure. Because pulmonary arterial pressure, pulmonary wedge pressure and right atrial pressure increased during bathing even though systemic vascular resistance and pulmonary arteriolar resistance decreased, increase in venous return was thought of as the biggest possibility. And because the patients with low cardiac function could not control the extent of increase in venous return, pulmonary arterial pressure increased markedly in patients with low cardiac function. The patients with myocardial infarction were classifed into a group showing elevation of pulmonary arterial pressure (PAP) and a group showing no elevation of PAP. The group showing elevation of PAP, compared with that without PAP elevation, included many cases of severe myocardial infarction deter-mined by Forrester's classification, Killip's classification and Peel's prognostic index at admission to hospital. Among these patients showing PAP elevation, there were more cases having low physical work capacity and low ejection fraction at discharge from hospital than among the patients without PAP elevation.

To investigate the effectiveness of Maobushisaishin-to (traditional Japanese herbal medicine; Tsumura TJ-127) in treating the common cold, a clinical comparison between Maobushisaishin-to and a general common cold drug was conducted using the sealed envelope method. The study involved 83 patients in the TJ-127 group and 88 patients in the general cold drug group. No differences in age, gender or the period from the onset of the disease to the beginning of treatment were observed between the two groups.
The results indicated greater than moderate improvement in 81.9% of the TJ-127 group, compared with 60.3% of the compound cold drug group (p<0.01). Further analysis of symptom diaries kept by the patients indicated that TJ-127 provided more rapid relief for symptoms such as fever, feeling feverish, coughing and phlegm than did the general cold drug. No side effects were observed for the TJ-127. These results suggest that TJ-127 is effective in the treatment of the common cold.

BACKGROUND/AIMS: The administration of liquid nutrients to patients is often accompanied by complications such as gastroesophageal reflux. To prevent gastroesophageal reflux, high-viscosity liquid meals are used widely, however, it still remains controversial whether high-viscosity liquid meals have any effect on the rate of gastric emptying. The present study was conducted with the aim of determining whether high-viscosity liquid meals had any effect on the rate of gastric emptying and mosapride might accelerate the rate of gastric emptying of high-viscosity liquid meals. METHODS: Six healthy male volunteers underwent 3 tests at intervals of > 1 week. After fasting for > 8 hours, each subject received one of three test meals (liquid meal only, high-viscosity liquid meal [liquid meal plus pectin] only, or high-viscosity liquid meal 30 minutes after intake of mosapride). A 13C-acetic acid breath test was performed, which monitored the rate of gastric emptying for 4 hours. Using the Oridion Research Software (beta version), breath test parameters were calculated. The study parameters were examined for all the 3 test conditions and compared using the Freidman test. RESULTS: Gastric emptying was significantly delayed following intake of a high-viscosity liquid meal alone as compared with a liquid meal alone; however, intake of mosapride prior to a high-viscosity liquid meal was associated with a significantly accelerated rate of gastric emptying as compared with a high-viscosity liquid meal alone. CONCLUSIONS: This study showed that high-viscosity liquid meals delayed gastric emptying: however, mosapride recovered the delayed rate of gastric emptying by high-viscosity liquid meals.

BACKGROUND/AIMS: The gastrointestinal motility effects of endogenous incretin hormones enhanced by dipeptidyl peptidase-IV (DPP-IV) inhibitors have not yet been sufficiently investigated. The aim of this study was to determine whether single pre-prandial sitagliptin, the DPP-IV inhibitor, administration might have an effect on the rate of liquid gastric emptying using the 13C-acetic acid breath test. METHODS: Ten healthy male volunteers participated in this randomized, two-way crossover study. The subjects fasted for overnight and were randomly assigned to receive 50 mg sitagliptin 2 hours before ingestion of the liquid test meal (200 kcal per 200 mL, containing 100 mg 13C-acetate) or the test meal alone. Under both conditions, breath samples were collected for 150 minutes following the meal. Liquid gastric emptying was estimated by the values of the following parameters: the time required for 50% emptying of the labeled meal (T1/2), the analog to the scintigraphy lag time for 10% emptying of the labeled meal (Tlag), the gastric emptying coefficient and the regression-estimated constants (beta and kappa), calculated by using the 13CO2 breath excretion curve using the conventional formulae. The parameters between the 2 test conditions were compared statistically. RESULTS: No significant differences in the calculated parameters, including T1/2, Tlag, gastric emptying coefficient or beta and kappa, were observed between the 2 test conditions. CONCLUSIONS: The present study revealed that single-dose sitagliptin intake had no significant influence on the rate of liquid gastric emptying in asymptomatic volunteers.

BACKGROUND/AIMS: The effects of Histamine-2 receptor antagonists and proton pump inhibitors on the gastrointestinal motility have not yet been sufficiently investigated. The aim of this study was to determine the effects of intravenous bolus administration of famotidine and omeprazole on the rate of gastric emptying using the continuous 13C breath test (BreathID system, Exalenz Bioscience Ltd, Israel). METHODS: Twelve healthy male volunteers participated in this randomized, 3-way crossover study. After fasting overnight, the subjects were randomly assigned to receive 20 mg of famotidine, 20 mg of omeprazole or 20 mL of saline alone by intravenous bolus injection before a test meal (200 kcal per 200 mL, containing 100 mg of 13C-acetate). Gastric emptying was monitored for 4 hours after the ingestion of test meal by the 13C-acetic acid breath test performed using the BreathID system. RESULTS: No significant differences in the calculated parameters, namely, the T1/2, Tlag, GEC, beta and kappa, were observed among the 3 test conditions. CONCLUSIONS: The study revealed that intravenous administration of gastric acid suppressant drugs had no significant influence on the rate of gastric emptying in comparison with that of saline alone as a placebo. Our results indicating the absence of any effect of either famotidine or omeprazole on accelerating the rate of gastric emptying suggest that both medications can be administered safely to patients suffering from hemorrhagic peptic ulcers who need to be kept nil by mouth from the viewpoint of possible acceleration of gastrointestinal motility in the clinical setting.

BACKGROUND/AIMS: There are few reports on the correlation between chewing gum and the gastrointestinal functions. But previous report showed use of chewing gum to be an effective method for controlling gastrointestinal symptoms. The aim of this study was to determine the correlation between chewing gum and gastric emptying using the continuous real time 13C breath test (BreathID system). METHODS: Ten healthy male volunteers participated in this randomized, 2-way crossover study. The subjects fasted overnight and were randomly assigned to chewing gum (Xylish, 2-3/1 tablet) for an hour following intake of a test meal (200 kcal/200 mL) or intake of the test meal alone. Gastric emptying was monitored for 4 hours after administration of the test meal by the 13C-acetic acid breath test performed continually using the BreathID system. RESULTS: No significant differences in the calculated parameters, namely, T1/2 (median, 111.82 vs 109.26 minutes; P = 0.575), Tlag (median, 53.28 vs 56.53 minutes; P = 0.333), gastric emptying coefficient (median, 3.58 vs 3.65; P = 0.285), regression-estimated constant beta (median, 1.85 vs 1.80; P = 0.575) and regression-estimated constant kappa (median, 0.61 vs 0.62; P = 0.959) were observed between the test meal alone group and the test meal and chewing gum group. CONCLUSIONS: This study showed that chewing gum had no effect on the rate of gastric emptying. Therefore, since chewing gum did not enhance the speed of gastric emptying, it may ameliorate gastrointestinal symptoms through other mechanisms, such as saliva and autonomic nervous system.

The Common Achievement Tests for medical students consists of Computer Based Testing (CBT) conducted before clinical training, and Objective Structured Clinical Examination (OSCE) conducted before and after clinical training. Since the publicization of the Common Achievement Tests for medical students before clinical training in 2023, the Committee for Reasonable Accommodation has been established within the Common Achievement Tests Organization (CATO), where reasonable accommodations for each exam are being considered. Reasonable accommodations begin with an assessment based on requests from candidates and proceed through constructive dialogue between candidates and universities. Additionally, recordings of practical training sessions are provided to facilitate objective assessments, enabling the provision of reasonable accommodations tailored to candidates’ participation in clinical training and internships, thereby ensuring smooth examination processes.
