[Objective]The present study investigated the relationship between subjective symptoms of katakori (shoulder stiffness) and shoulder hardness which was examined both with clinical palpation and a mechanical device, as well as the correlation between these two measurements.
[Methods]Subjects were enrolled to the study if they had a stiff shoulder on the day of the visit (katakori group, n = 60) or if they had no experience of katakori in their lifetime (non-katakori group, n = 10). The intensity of the katakori was evaluated with a visual analogue scale (VAS). Shoulder hardness was evaluated at acupoint Jianjing (GB21) and at the point where the subject felt the most intensive symptom by both palpation of experienced acupuncturists who were unaware of the allocation and a hardness meter. The method of acupuncture treatment was decided by acupuncturists who were not an evaluator of the hardness.
[Results and Discussion]There was no significant relationship in the hardness measured with the device and palpation between the katakori group and non-katakori group. Also, the intensity of katakori (VAS) and the changes after treatment showed no significant correlation with the hardness and its changes. These results support the validity of our clinical experience that patients who complain of severe shoulder stiffness do not always have a hard shoulder.

The purpose of this study was to evaluate the association between subjective usefulness of pedometer and step count, exercise adherence, and the possibility of a pedometer helping exercise adherence.
The subjects were 106 community-dwelling citizens (mean age±SD, 66±5) who were put on an individual exercise program in addition to walking. The targeted step count was 8000 steps/day. Every subject wore a pedometer that registers 7 days of physical activity.
The rate of adherence was 98.1%, and about 73% of subjects answered that using a pedometer is useful for physical activity. There was no difference in exercise habit at baseline between subjects answering useful or not useful.
Only in the case of females, was step count and prevalence of targeted 8000 steps significantly higher in the group who felt a pedometer was useful than in the group who didn't feel it useful. However, in the group of males who felt the usefulness of a pedometer, step count significantly increased during the 3 months. In addition, the females who reached their targeted step count performed better in the 10 m hurdle walk and 6 min walk than those who could not reach the targeted step count.
The awareness of self-health wellness, without the anxiety of physical fitness and adherence to exercise was higher in the subjects who felt a pedometer was useful than in the subjects who didn't.
The subjects who felt a pedometer was useful achieved their targeted number of steps and increased walking ability and tended to adhere better to physical activity.
It is suggested that a pedometer motivates adherence to physical activity and is useful for helping exercise adherence in the future. However, we need a randomized control trial for determining the relationship between exercise adherence and using a pedometer.

BACKGROUND: Both endoscopic ultrasound-guided celiac plexus neurolysis (EUS-CPN) and tumor ablation using ethanol are very common procedures, and the utility of these therapies has already been reported in prominent journals. However, their effectiveness appears temporary and insufficient, especially EUS-CPN. We therefore have to consider new reagents for improving the results. The present study examined the best concentration of ethanol and povidone iodine mixed with atelocollagen for more effective therapies. METHODS: The effects of the new reagents were confirmed in three live pigs. At first, we injected three kinds of reagents (including indigo carmine) in three separate areas of para-aortic tissue under EUS guidance in one pig. At more than 4 hours after injection, we checked ethanol injection sites after dissection. In next study, we performed EUS-guided injection of a total of six kinds of reagents (two kinds of ethanol, three kinds of povidone iodine, and control atelocollagen) into the livers of two living pigs. After 2 weeks, we examined tissue damage to the liver in the two pigs. RESULTS: The 75% ethanol (absolute ethanol 3.75 mL + 1% atelocollagen 1.25 mL + a very small amount of indigo carmine) was seen like blue gel, and still remained in the para-aortic tissue. Brownish areas of povidone iodine mixed with 3% atelocollagen exhibited clear, regular borders with greatly reduced infiltration into surrounding tissue compared to others. CONCLUSION: We concluded that 75% ethanol mixed with 1% atelocollagen appears optimal for EUS-CPN. Povidone iodine mixed with 3% atelocollagen may be suitable for small tumor ablation therapy.

Background and Aims: The gastrointestinal motility effects by carbonated water have not yet been sufficiently investigated. The aim of this study was to determine whether single pre-prandial carbonated water administration might have an effect on the rate of liquid gastric emptying using the 13C-acetic acid breath test. Methods: Eight healthy volunteers (F/M; 3/5) participated in this randomized, 3-way crossover study. The subjects fasted overnight and were randomly assigned to receive 200mL of carbonated water before ingestion of the liquid test meal (200 kcal per 200 mL, containing 100 mg 13C acetate) or 200mL of carbonated water before the test meal or the test meal alone. Under all conditions, breath samples were collected for 150 min following the meal. Liquid gastric emptying was estimated by the values of the following parameters: T1/2, Tlag, the gastric emptying coefficient (GEC) and the regression-estimated constants (β and κ), calculated using the 13CO2 breath excretion curve using the conventional formulae. The parameters between the 3 test conditions were compared statistically. Results: Carbonated water significantly decreased k and beta, but T1/2, Tlag and GEC remained unchanged. Conclusions: The present study revealed that carbonated water has dual effects on liquid emptying: an initial acceleration with a subsequent deceleration in asymptomatic volunteers.
