One hundred and seven cases of sudden death in bathtubs, bath-death, were reviewed from the records of inquest by the Naruko Office of Miyagi Prefectural Police from 1984 to 1997. Eighty-four cases were of visitors staying at hot-spring hotels and 33 cases were of local residents. The number of cases of local residents increased by 1.8 times in the latter 7 years as compared with that of the first 7 years of the period investigated, probably because of aging of the population. The annual number of bath-death cases among visitors varied on a large cycle of over 10 years, seemingly in correlation with business conditions because it showed a strong correlation with the official discount rate. The average mortality rate of visitors was much higher than that of residents in the best business conditions and lowered to the same level as that of residents in the worst business conditions. One reason for such changes in mortality rate may be that while a majority of trips in the best business conditions were for pleasure, sometimes accompanying fatigue and stress of aged members including 85% or more of male, as business conditions became worse, the purposes of trips changed into recuperation and sightseeing. The number of bath-death cases among visitors increased every April and December, probably because of social customs such as new fiscal year parties, year-end parties, and so on. Bath-death cases occurred more frequently among those over 70 years, and were seen more at midnight, in winter, after drinking, at a bath temperature over 40 degree centigrade, and for a large temperature difference between the room and bath. Sixty-six percent of the bath-death cases were caused by cardiovascular diseases; 23%, by cerebrovascular events; and 11%, by other accidents.

Background: Necrotizing fasciitis is a rare but severe condition associated with high mortality. We encountered a patient with severe and rapidly progressing necrotizing fasciitis. Patient: A 40-year-old male was hit by a tractor and received a wide laceration wound spanning the length of his posterior thigh. Soon after the accident, the wound was washed and debridement was performed. Two days postoperatively, we observed septic changes in the wound and diagnosed this condition as necrotizing fasciitis. Consequently, the patient's leg was amputated at the thigh. The patient, however, developed toxic shock syndrome after the amputation. Endotoxin adsorption using a polymyxin B-immobilized fiber column was performed for 2 days. Finally, a hip joint amputation was performed after 11 days, following which the patient's general condition gradually improved. Discussion: Treatment for necrotizing fasciitis should be initiated promptly. Early debridement is associated with a significant decrease in mortality. In severe conditions, endotoxin and cytokine removal by blood purification is one of the most effective treatments. Although group A streptococci are widely known as "flesh-eating bacteria," we should also consider a wide variety of pathogenic organisms to be the probable cause of severe necrotizing fasciitis. Conclusion: Management of necrotizing fasciitis requires careful investigation as well as an aggressive therapeutic approach, which may include urgent surgical intervention. In addition to surgery, endotoxin adsorption therapy should be considered.

BACKGROUND/AIMS: The aim of this study was to examine the convenience of the quality of life and utility evaluation survey technology (QUEST) questionnaire and the frequency scale for the symptoms of gastroesophageal reflux disease (FSSG) questionnaire as self-assessment diagnostic instrument. METHODS: This was a two-way crossover study conducted over 6 weeks from September 2010 to November 2010. The subjects were 60 consecutive patients admitted to the Hiratsuka city hospital with a gastrointestinal condition, regardless of the coexistence of heartburn. They were assigned to fill in both the QUEST and FSSG questionnaires in random order. We analyzed the time taken to complete the questionnaires, whether subjects asked any questions as they filled in the questionnaire, and the questionnaire scores. RESULTS: Comparison of the QUEST and the FSSG revealed significant differences in the completion time (196.5 vs. 97.5 seconds, respectively; P < 0.0001) and in whether subjects asked any questions (37 vs. 15 subjects, respectively; P < 0.0001). Completion time in QUEST scores of > or = 4 was lower than < 4 (170.5 vs. 214.0 seconds, respectively; P = 0.022), and the QUEST score was significantly higher without questions than with question (3 vs. 1 points, respectively; P = 0.025). CONCLUSIONS: This study revealed that the FSSG questionnaire may be easier for Japanese subjects to complete than the QUEST questionnaire.

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: 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: 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.
