Purpose: The purpose of this study was to determine whether the impact on the body during landing in dancers is less than in non-dancers by using accelerometers and motion analyzer.Method: Eleven ballet dancers and 11 non-dancers participated in this study. Each subject was instructed to perform 3 types of landing from a height of 30cm: landing, silent landing and raise up landing. Markers were put on the iliac crest, greater trochanter, knee joint, lateral malleolus. The peak vertical and horizontal accelerations of the lumbar, peak vertical acceleration of the greater trochanter and the peak flexion angles of the hip and knee joints were measured after the trials.Result: In the raise up landing, the peak vertical acceleration of the lumbar region in dancers was less than that in non-dancers (p < 0.01), and the peak knee-flexion angle in dancers was greater than that in non-dancers (p < 0.01). There were no differences between the peak hipflexion angles of dancers and non-dancers.Conclusion: The impact on the lumbar during raise up landing was less in dancers. In raise up landing, the trunk tends to be fixed when the dancer stands upright. Moreover, dancers attenuated the shock to the lumbar region by increasing the knee-flexion angle to a greater extent than the non-dancers did. This result may indicate the importance of the knee joint flexion in attenuating the shock during landing and show that dancers excel in using their knees flexibly.

Purpose: We report a case in which oral sodium valproate through a percutaneous endoscopic gastrostomy (PEG) tube for palliative decompression drainage in inoperable ileus achieved an effective drug concentration and ameliorated delirium and extrapyramidal side effects. Case Report: The patient was a male in his seventies who suffered from bladder cancer. He underwent PEG because of paralytic ileus with cancerous peritonitis. He had been receiving continuous intravenous infusion of haloperidol for the management of delirium, but needed to discontinue treatment with this agent due to tremor, an extrapyramidal side effect of haloperidol. Oral sodium valproate was therefore administered through the PEG tube for palliative decompression drainage. Plasma valproate concentrations showed effective levels, and his irritability was relieved. A good combination of sodium valproate and quetiapine fumarate allowed successful reduction of and eventual withdrawal from haloperidol, and tremor then improved. Conclusion: We often encounter difficulty with symptom control for patients who cannot use oral medications. When medication by other routes is difficult, this case suggests that sodium valproate through a PEG tube for palliative decompression drainage may be useful as a last resort for improving delirium.

The purpose of this study was to examine the association of muscle mass and muscle strength with mobility limitation and history of falls in community-dwelling older adults. This cross-sectional study included 420 older adults (207 men, 213 women, 73.7 ± 5.2 years). The participants were classified to following four groups according to their appendicular skeletal muscle mass index (AMI) which was evaluated by bioelectric impedance analysis for skeletal muscle mass in the arms and legs and appendicular skeletal muscle strength Z-score (ASZ) which was calculated from hand-grip strength for upper extremity and peak reaction force during sit-to-stand movement for lower extremity: 1) Low AMI and Low ASZ, 2) Low AMI alone, 3) Low ASZ alone, and 4) Normal. Mobility limitation and history of falls were assessed as a self-reported questionnaire. We used a poisson regression analysis with an adjustment for age, body mass index, knee pain, and back pain. The prevalence of mobility limitation was significantly higher at Low AMI and Low ASZ (relative risk, RR = 5.09, 95% confidence interval, CI 2.08–12.46) and Low ASZ alone (RR = 4.79, 95% CI 2.01–11.39) in men and Low AMI and Low ASZ (RR = 1.70, 95% CI 1.01–2.88) in women than Normal. History of falls was significantly associated with Low ASZ alone (RR = 2.00, 95% CI 1.02–3.91) just in men. These results suggest that low muscle strength per weight rather than low muscle mass per height is an important risk factor to increase mobility limitation in both genders and falls in men.

Object: A multicenter survey was conducted to investigate the status of use of supplements and related problems in patients with diabetes mellitus.
Methods: A questionnaire was mailed to institutions where members of the Drug Information Section, Tokyo Hospital Pharmacists Association, worked, and hospitalized patients with diabetes mellitus were surveyed with a questionnaire.
Results: The response rate of the questionnaire was 85%, and 22 patients reported taking supplements.  The most common motivation to purchase supplements was a recommendation from an acquaintance, followed by a recommendation from a family member and TV. Only 9.1% of the patients consulted healthcare professionals when purchasing supplements.  The patients who did not follow the dosage and administration instructions and those who were not aware of precautions regarding proper use accounted for 31.8% and 63.6%, respectively.  The proportion of patients who did not inform their physicians about the use of supplements was 65.2%, and 4.5% reported some health damage (rash).
Conclusion: Our results revealed that supplements were used without careful consideration and were not administered properly, suggesting that scientific evaluation of efficacy and safety was warranted in future studies.  It is important for pharmacists to actively collect information on patient use of supplements and share the information within the medical team.

Objective: Gait speed is regulated by varying gait parameters depending on the diverse contexts of the environment. People with Parkinson’s disease (PwPD) have difficulty adapting to gait control in their environment; however, the relationships between gait speed and spatiotemporal parameters in free-living environments have not been clarified. This study aimed to compare gait parameters according to gait speed in clinics and free-living environments. Methods: PwPD were assessed at the clinic and in a free-living environment using an accelerometer on the lower back. By fitting a bimodal Gaussian model to the gait speed distribution, gait speed was divided into lower and higher speeds. We compared the spatiotemporal gait parameters using a 2 × 2 (environment [clinic/free-living] × speed [lower/higher]) repeated-measures analysis of variance. Associations between Parkinson’s disease symptoms and gait parameters were evaluated using Bayesian Pearson’s correlation coefficients. Results: In the 41 PwPD included in this study, spatiotemporal gait parameters were significantly worse in free-living environments than in clinics and at lower speeds than at higher speeds. The fit of the walking speed distribution to the bimodal Gaussian model (adjustability of gait speed) in free-living environments was related to spatiotemporal gait parameters, severity of Parkinson’s disease, number of falls, and quality of life. Conclusion The findings suggest that gait control, which involves adjusting gait speed according to context, differs between clinics and free-living environments in PwPD. Gait assessments for PwPD in both clinical and free-living environments should interpret gait impairments in a complementary manner.

　　Hyperbaric oxygen (HBO) therapy for acute carbon monoxide (CO) poisoning is performed after oxygen therapy and breathing therapy. The usefulness of HBO therapy in emergency treatment has been reported. In this study, we examined the effectiveness of HBO for CO poisoning that was performed at our hospital over the past 5 years. Subjects were 23 patients who had HBO therapy for CO poisoning in the period January 2008-November 2013. The male to female ratio of the cases was 14:9 and the mean age was 54.6±20.8 years. The cause was suicide in 39.1% of cases and accident in 60.9%. The mean number of treatments was 5.4±6.8. The atmosphere absolute was 2ATA:2.8ATA=12:11. The ratio of direct conveyance of the patient to our hospital to indirect conveyance of the patient from another hospital was 15:8. The effectiveness of HBO therapy at the time of discharge was 73.9%. However, delayed neuropsychiatric sequelae (DNS) was detected in 3 of the 23 cases of CO poisoning. No correlations were found between elapsed time after CO inhalation and various blood parameters. However, time to start of therapy is important for DNS, and our results suggest that early treatment at a hospital with a hyperbaric chamber is necessary.

BACKGROUND/AIMS: It is often difficult to manage acute cholecystitis after metal stent (MS) placement in unresectable malignant biliary strictures. The aim of this study was to evaluate the feasibility of endoscopic ultrasonography-guided gallbladder drainage (EUS-GBD) for acute cholecystitis. METHODS: The clinical outcomes of 10 patients who underwent EUS-GBD for acute cholecystitis after MS placement between January 2011 and August 2018 were retrospectively evaluated. The procedural outcomes of percutaneous transhepatic gallbladder drainage (PTGBD) with tube placement (n=11 cases) and aspiration (PTGBA) (n=27 cases) during the study period were evaluated as a reference. RESULTS: The technical success and clinical effectiveness rates of EUS-GBD were 90% (9/10) and 89% (8/9), respectively. Severe bile leakage that required surgical treatment occurred in one case. Acute cholecystitis recurred after stent dislocation in 38% (3/8) of the cases. Both PTGBD and PTGBA were technically successful in all cases without severe adverse events and clinically effective in 91% and 63% of the cases, respectively. CONCLUSIONS: EUS-GBD after MS placement was a feasible option for treating acute cholecystitis. However, it was a rescue technique following the established percutaneous intervention in the current setting because of the immature technical methodology, including dedicated devices, which need further development.
