    Notes: Abstract. Background: The purpose of this study was to assess the diagnostic value of endoscopic ultrasound (EUS) and intraductal ultrasound (IDUS) in the detection of small pancreatic tumors. Methods: EUS was performed in 166 patients with verified pancreatic disease. IDUS was performed in 46 patients. A microprobe was introduced into the main pancreatic duct through the papilla of Vater using the duodenoscope. Results: EUS was valuable in the detection of small pancreatic tumors. Ductal adenocarcinomas smaller than 1 cm were demonstrated as a hypoechoic mass with a central irregular hyperechoic area. EUS and IDUS were useful in the characterization of intraductal paillary tumors (ductectatic mucinous tumors). EUS demonstrated nodular excrescences, and IDUS depicted papillary proliferation of the duct epithelium, which are characteristic of carcinomas and adenomas but not of hyperplasia. Internal architecture of cystic neoplasms was clearly depicted by EUS, and differentiation of serous and mucinous tumors was readily achieved. A tumor as small as a 5-mm islet cell was demonstrated on EUS because islet cell tumors are very hypoechoic. Conclusion: EUS and IDUS are relatively noninvasive procedures and are useful in the detection of small tumors and differentiation of pancreatic diseases.

    Notes: Ten cases of gynecologic malignancies, including three endometrial, two ovarian and four cervical carcinomas, were studied for the expression of a 185 kDa protein (ErbB-2), coded by a proto-oncogene, c-erbB-2, in primary lesions as well as in metastatic lesions. Positive immunoreactivity was observed in all primary adenocarcinomas but not from squamous cell carcinomas. Many adenocarcinoma cells in distant metastatic sites or in tertiary lymph nodes were strongly stained for ErbB-2. These metastatic cells also showed an expression of proliferating cell nuclear antigen (PCNA). Detection of ErbB-2 mRNA by a reverse-transcription polymerase chain reaction showed that the transcription occurred exclusively in adenocarcinomas. To our knowledge, this is the first report demonstrating ErbB-2 expression in distant metastatic lesions of gynecologic cancers.

    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.

    Notes: To evaluate the efficacy and safety of two 1-week low-dose triple-therapy drug regimens involving antisecretory drugs for Helicobacter pylori infection, 99␣patients with H. pylori infection were treated with either lansoprazole or ranitidine used together with clarithromycin and metronidazole.〈section xml:id="abs1-2"〉〈title type="main"〉Methods:The drug combination and administration periods in the proton pump inhibitor group were lansoprazole 30 mg o.m., clarithromycin 200 mg b.d. and metronidazole 250 mg b.d., all given for 7 days (LCM group). The ranitidine group received ranitidine 150 mg b.d., clarithromycin 200 mg b.d. and metronidazole 250 mg b.d. also for 7 days (RCM group). The presence or absence of H. pylori was determined from gastric biopsy specimens taken from both the antrum and the body, by smear, culture and tissue section (Giemsa stain). Cure was defined as failure to find evidence of H. pylori infection 4 weeks after antimicrobial therapy had ended.〈section xml:id="abs1-3"〉〈title type="main"〉Results:The cure of H. pylori infection was 88% in the LCM group (44 of 50; 95% confidence interval (CI) = 79–97%) and 92% in the RCM group (45 of 49; 95% CI = 84–99%). The incidence of adverse events was 16% and 18% for the two groups, respectively.〈section xml:id="abs1-4"〉〈title type="main"〉Conclusions:No significant differences in cure rate and safety profiles were noted between the two regimens, suggesting that moderate acid inhibition using an H2-blocker is sufficient to achieve optimal H. pylori eradication.

    Notes: Abstract  We report on an HTLV-I carrier showing clonal proliferation of γδ-T lymphocytes associated with chronic neutropenia and rheumatoid arthritis (RA). A 75-year-old Japanese woman had a 20-year history of RA and was found to have neutropenia and lymphocytosis by routine examinations. Her white cell count was 5,800/μl with 89% lymphocytes. The proliferating γδ-lymphocytes did not show the typical morphology of large granular lymphocytes (LGL) and were positive for CD3, TCRδ1, and HLA-DR but negative for CD4, CD8, and δTCS1. Clonally rearranged TCRγ-chain (Jγ) and TCRβ-chain (Cβ1) genes were detected by Southern blot analysis. Clonality of these proliferating γδ-T cells was confirmed by CDR3 size analysis for the TCRδ-chain. Anti-HTLV-I antibody was positive and the pX region of HTLV-I proviral DNA was detected by PCR analysis, but clonal integration of HTLV-I proviral DNA was not detected by Southern blotting analysis. The patient's clinical course has been stable, except for infrequent infectious episodes. The association of HTLV-I/II infection with T-LGL leukemia has been reported by several groups, although most cases exhibit TCRαβ+ type T cells. Analysis of the junctional sequence of TCR on T-LGL leukemia cells may clarify the role of HTLV-I/II infection in clonal T-cell proliferation.

    Notes: Abstract A new adhesion process of glass to metal was developed based on the redox reaction without oxidation of the metal surface. PbO-based glasses were strongly adhered to nickel metal at low temperature (400–500 °C) in a low-oxygen atmosphere (〈 0.1 p.p.m.). The interfaces between glasses and metal were analysed by SEM-EDS. It was found that the reaction layer and lead metal were formed by the redox reaction at the interface. In the case of the adhesion of PbO-based glasses containing CuO to nickel, the main reduced product in the glass was Cu2O, and lead was not detected. The redox reaction was simulated by a thermodynamic equilibrium theory; the results agreed with the analysis by SEM-EDS.

    Notes: Abstract Using a pulsed muon beam, we have investigated the microscopic μ+ behavior in solid H2 and D2 down to 0.6 K by the μ+SR method. From the studies of μ+ spin relaxation phenomena in solid para‐ H2 and ortho‐ D2, we have found that μ+ forms three distinct microscopic states; H2μ+( D2μ+)(20\sim25\%), muonium (15\sim20\%) and μ+(\sim60\%). In H2μ+, the μ+ spin is depolarized in solid para‐ H2 and a local magnetic field Bloc=1\sim2 G is deduced from LF‐μ+SR measurements. The magnitude of Bloc is inconsistent with the magnetic dipolar field (\sim25 G) expected from the magnetic moments of two protons in the H2μ+ molecule and suggests that the H2μ+ molecule might be in the rotationally excited state. From LF‐μ+SR measurements, muonium and μ+ have been found to diffuse in solid o‐ D_2. The diffusion rate of muonium is two order of magnitude larger than that of μ+.
