Temporomandibular arthrosis, which is accompanied by pain in the jaw joint and surrounding tissue, as well as clicking and disorder of jaw opening or movement, is common in dentistry field. However current treatment often does not result in improvement. We carried out acupuncture treatment for temporomandibular arthrosis without organic disorders including psychogenic ones. 12 patients (one male and 11jfemales) referred from the department of dentistry and oral surgery of our hospital underwent acupuncture treatment once or twice a week. In each treatment, electro-acupuncture was performed for fifteen minutes through chinese needles applied to Fuchi, Eifu, Anmin, Kensei, Taiyo, Gekan, Kyosha, Ten-yo, Kensei and Gokoku. Remarkable results were obtaied in 4 of these cases, effective in 2 cases, rather-effective in 3, and non-effectiveI in 3 cases, a 75% effectivectiveness ratio.

Massive rotator cuff tears (RCTs) are complicated by muscle atrophy, fibrosis, and intramuscular fatty degeneration, which are associated with postoperative tendon-to-bone healing failure and poor clinical outcomes. We evaluated muscle and enthesis changes in large tears with or without suprascapular nerve (SN) injury in a rat model. Methods: Sixty-two adult Sprague-Dawley rats were divided into SN injury (+) and SN injury (–) groups (n=31 each), comprising tendon (supraspinatus [SSP]/infraspinatus [ISP]) and nerve resection and tendon resection only cases, respectively. Muscle weight measurement, histological evaluation, and biomechanical testing were performed 4, 8, and 12 weeks postoperatively. Ultrastructural analysis with block face imaging was performed 8 weeks postoperatively. Results: SSP/ISP muscles in the SN injury (+) group appeared atrophic, with increased fatty tissue and decreased muscle weight, compared to those in the control and SN injury (–) groups. Immunoreactivity was only positive in the SN injury (+) group. Myofibril arrangement irregularity and mitochondrial swelling severity, along with number of fatty cells, were higher in the SN injury (+) group than in the SN injury (–) group. The bone-tendon junction enthesis was firm in the SN injury (–) group; this was atrophic and thinner in the SN injury (+) group, with decreased cell density and immature fibrocartilage. Mechanically, the tendon–bone insertion was significantly weaker in the SN injury (+) group than in the control and SN injury (+) groups. Conclusions: In clinical settings, SN injury may cause severe fatty changes and inhibition of postoperative tendon healing in large RCTs. Level of evidence: Basic research, controlled laboratory study

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 and Aims：Sarcopenia is associated with autologous hematopoietic stem cell transplantation (auto-HSCT) -related outcomes in patients with malignant lymphoma (ML). The aims of this study were to investigate changes in skeletal muscle mass after auto-HSCT and risk profiles for sarcopenia after HSCT.Methods：We enrolled 25 patients with refractory ML (age, 57 years [20-69 years]；female/male, 11/14；body mass index, 21.7 kg/m2 [18.9-29.6 kg/m2]). Skeletal muscle mass was evaluated using the psoas muscle index (PMI) measured on computed tomography before and after auto-HSCT. In addition, visceral fat area (VFA) was also measured. Independent factors and profiles associated with a decrease in PMI were evaluated using multivariate and decision-tree analyses, respectively.Results：The PMI was significantly decreased after auto-HSCT (p＝0.0288). A logistic regression analysis revealed that the decreases in PMI and VFA were related. According to the decision-tree analysis, the PMI measured prior to auto-HSCT was selected as the initial branch. Of the patients with a PMI of＜3.74 cm2/m2, 84％ showed a decrease in PMI. Of the patients with a PMI of ≥3.74 cm2/m2, the VFA measured prior to auto-HSCT was the second branch. All the patients with a VFA of ≥115.0 cm2 had decreased PMI.Conclusions：We demonstrated that skeletal muscle mass decreased after auto-HSCT in the patients with ML. The patients with either a PMI of＜3.74 cm2/m2 or a VFA of ≥105.0 cm2 before auto-HSCT were at risk of decreased skeletal muscle mass.
