消化器内科外来におけるhospital anxiety and depression scale(HAD尺度)日本語版の信頼性と妥当性の検討

Abstract: This study examined the validity of the Japanese version of the hospital anxiety and depression scale (HAD) in a gastro-intestinal outpatient clinic. One hundred and twenty-three men and 142 women consulting a gastro-intestinal outpatient clinic at a primary care hospital in Kyoto during 1995 were surveyed. Item-remainder correlation and internal consistency were examined for reliability. Concurrent validities were examined using the stait-trait anxiety inventory (STAI) and Zung's self-rating depression scale (SDS). The prevalence of psychiatric disorder in this population ranged from 27% to 39%. Cronbach's coefficients were greater than 0.8 for the anxiety subscale and more than 0.7 for the depression subscale. Spearman's correlation of the anxiety subscale scores and the STAI were r = 0.678 for men, and r = 0.717 for women. The correlation of depression subscale scores and SDS were r = 0.457 for men, and r = 0.565 for women. It is suggested that the use of the HAD to general hospital outpatients clinic would facilitate detecting emotional disorders in outpatients.

Discovery of Novel Splice Forms and Functional Analysis of Cancer-Specific Alternative Splicing in Human Expressed Sequences

Abstract: We report here a genome-wide analysis of alternative splicing in 2 million human expressed sequence tags (ESTs), to identify splice forms that are up-regulated in tumors relative to normal tissues. We found strong evidence (P < 0.01) of cancer-specific splice variants in 316 human genes. In total, 78% of the cancer-specific splice forms we detected are confirmed by human-curated mRNA sequences, indicating that our results are not due to random mis-splicing in tumors; 73% of the genes showed the same cancer-specific splicing changes in tissue-matched tumor versus normal datasets, indicating that the vast majority of these changes are associated with tumorigenesis, not tissue specificity. We have confirmed our EST results in an independent set of experimental data provided by human-curated mRNAs (P-value 10(-5.7)). Moreover, the majority of the genes we detected have functions associated with cancer (P-value 0.0007), suggesting that their altered splicing may play a functional role in cancer. Analysis of the types of cancer-specific splicing shifts suggests that many of these shifts act by disrupting a tumor suppressor function. Sur prisingly, our data show that for a large number (190 in this study) of cancer-associated genes cloned originally from tumors, there exists a previously uncharacterized splice form of the gene that appears to be predominant in normal tissue.

[Per-oral endoscopic myotomy (POEM) for esophageal achalasia].

Abstract: BACKGROUND Peroral endoscopic myotomy (POEM) was developed by our group to provide a less invasive permanent treatment for esophageal achalasia. PATIENTS AND METHODS POEM was performed in 17 consecutive patients with achalasia (10 men, 7 women; mean age 41.4 years). A long submucosal tunnel was created (mean length 12.4 cm), followed by endoscopic myotomy of circular muscle bundles of a mean total length of 8.1 cm (6.1 cm in distal esophagus and 2.0 cm in cardia). Smooth passage of an endoscope through the gastroesophageal junction was confirmed at the end of the procedure. RESULTS In all cases POEM significantly reduced the dysphagia symptom score (from mean 10 to 1.3; P = 0.0003) and the resting lower esophageal sphincter (LES) pressure (from mean 52.4 mmHg to 19.9 mmHg; P = 0.0001). No serious complications related to POEM were encountered. During follow-up (mean 5 months), additional treatment or medication was necessary in only one patient (case 17) who developed reflux esophagitis (Los Angeles classification B); this was well controlled with regular intake of protein pump inhibitors (PPIs). CONCLUSIONS The short-term outcome of POEM for achalasia was excellent; further studies on long-term efficacy and on comparison of POEM with other interventional therapies are awaited.
