    Notes: SUMMARY  Contracture of jaw-closing muscles is one of the causes of limitations of jaw opening. In contracture patients who have no history of trauma or infection, it is not easy to distinguish contracture from temporomandibular joint (TMJ) closed lock (TCL). The purpose of this study was to clarify whether there is any difference between electromyographic (EMG) activities of jaw muscles during jaw opening in patients with TCL and patients with masseter muscle contracture (MMC). The MMC-patient group consisted of one male and 11 females with no history of trauma or infection. The TCL-patient group consisted of one male and 11 females. Ten of the MMC patients showed certain types of EMG activities in masseter muscles (and eight in temporal muscles) during jaw opening. However, particular EMG activities were not observed in most of the TCL patients. The integral values in masseter muscles and in temporal muscles at the maximum opening position were significantly higher in the MMC-patient group than those in the TCL-patient group. These findings demonstrate that the EMG pattern of MMC patients without a history of trauma or infection is different from that of TCL patients. Therefore, EMG analysis of jaw-closing muscles during jaw opening is expected to be useful for differential diagnosis between MMC and TCL.

    Notes: Aim: Various treatments for hypertrophic and keloid scars have been attempted including electron beam irradiation, local triamcinolone injection, oral tranilast administration, use of silicone sheets, and compression therapy using splints. Among them, we have been attempting silicone cushion patching on hypertrophic scar. Methods: Twenty cases (10 males, 10 females) with hypertrophic scar were treated with silicone cushion. Scar surfaces were kept in contact with silicone cushion for as long periods of time as possible every day. Results were assessed in scores using objective findings (redness, bulging, induration) and subjective symptoms (itching, spontaneous pain, tenderness). Results: As for objective findings, redness remained unchanged in one case, but bulging and induration were found improved in all cases. As for subjective symptoms, itching and tenderness were found improved in all cases and clinical course considered proving usefulness of the treatment was obtained. Conclusions: Silicone cushions have highly viscous silicone oil enclosed in the silicone pack designed to generate negative charge electrostatic fields. Generation of adequate and sustaining electrostatic fields is important for useful clinical effect to exhibit on hypertrophic scar recession. Generation of negative charge electrostatic fields was confirmed on potential determination data with an electrostatic field meter as well.

    Notes: Rabeprazole sodium is a proton pump inhibitor.〈section xml:id="abs1-2"〉〈title type="main"〉Aim:To evaluate the efficacy and safety of 1-week triple therapy with rabeprazole, amoxycillin and clarithromycin for the eradication of Helicobacter pylori.〈section xml:id="abs1-3"〉〈title type="main"〉Methods:A total of 100 subjects with H. pylori were randomly divided into two groups of 1-week triple therapy with rabeprazole 10 mg b.d., amoxycillin 750 mg b.d. and either clarithromycin 200 mg b.d. (RAC400, n=50) or clarithromycin 400 mg b.d. (RAC800, n=50). Endoscopic examination with four biopsies (two specimens from the antrum and two from the gastric body) was performed. The status of H. pylori infection was determined using culture and histology (Giemsa stain) of the biopsy specimens. Sensitivity to clarithromycin was determined using the E-test: MIC 〉 8 g/mL was considered to be resistant, whereas MIC 〈 2 g/mL was considered to be sensitive. Cure was defined as no evidence of H. pylori infection 1 month after completion of treatment.〈section xml:id="abs1-4"〉〈title type="main"〉Results:There were no significant differences in the clinical characteristics of the two groups. Eradication rates (intention-to-treat and per protocol, respectively) were: RAC400: 86% (95% CI: 76–95%) and 89% (95% CI: 80–97%); RAC800: 94% (95% CI: 87–100%) and 97% (95% CI: 94–100%). There was no significant difference between the eradication rates of either regimen. Three subjects with failed eradication in the RAC400 group were all infected with a clarithromycin-resistant strain before beginning the therapy. Haemorrhagic colitis was the only severe adverse event, which was observed in one patient in the RAC800 group.〈section xml:id="abs1-5"〉〈title type="main"〉Conclusion:One-week triple therapy with rabeprazole, amoxycillin and low-dose clarithromycin is effective for the eradication of H. pylori infection.

    Notes: Helicobacter pylori infection is a major cause of the progress of gastric glandular atrophy, a high-risk background factor in the development of gastric cancer. Regression of gastric atrophy is critical to prevention of cancer by H. pylori eradication treatment. However, it is controversial whether gastric atrophy regresses after H. pylori eradication.〈section xml:id="abs1-2"〉〈title type="main"〉Aim:To determine the most sensitive and appropriate biopsy site for evaluation of regression of atrophy after treatment.〈section xml:id="abs1-3"〉〈title type="main"〉Subjects and methods:Thirty-eight patients who showed regression of gastric atrophy in histology after treatment were investigated. Four biopsy specimens from the lesser and greater curvatures in the antrum and corpus were evaluated before and after treatment according to the Updated Sydney System.〈section xml:id="abs1-4"〉〈title type="main"〉Results:Regression of atrophy after treatment was seen in 30 of 38 biopsy specimens from the lesser curvature of the corpus (79%), and this site was most sensitive. Odds ratio of this site to the others was 8.28. Regression of atrophy in this site was observed at 12.2 months in the younger patients and 15.9 months in the elder patients.〈section xml:id="abs1-5"〉〈title type="main"〉Conclusion:Biopsy sampling from the lesser curvature of the corpus is the most sensitive and appropriate for evaluation of regression of gastric atrophy after H. pylori eradication treatment.
