Relationship between Kyphosis and Barrett's Esophagus in Japanese Patients.
Summary of "Relationship between Kyphosis and Barrett's Esophagus in Japanese Patients."
Background Kyphosis is a risk factor for the presence of hiatal hernia, which is a strong predictor of Barrett's esophagus. However, the association between kyphosis and Barrett's esophagus has not yet been clarified. To investigate this relationship, the Cobb angle, a marker of kyphosis, was measured in patients with and without Barrett's esophagus. Methods From January 2006 to December 2010, 26 patients with long-segment Barrett's esophagus (LSBE) were retrospectively enrolled. As the comparative groups, 100 consecutive patients with short-segment Barrett's esophagus (SSBE) and 100 consecutive control patients without Barrett's esophagus were also enrolled in this study. Cobb angles were measured on lateral chest radiographs, and kyphosis was defined as a Cobb angle of greater than 50°. Kyphosis, along with other patient characteristics, were evaluated as possible predictors for SSBE and LSBE. Results The mean Cobb angles in the non-BE, SSBE, and LSBE groups were 31.6° (95% CIs, 29.3°-33.9°), 34.8° (32.1°-37.4°) and 49.4° (44.9°-53.9°), respectively. Statistically significant differences were found between the LSBE and the other 2 groups (p<0.001). The mean Cobb angles were 33.3°±12.4° and 37.0°±14.1°, respectively in patients without and with hiatal hernia (p=0.039). Predictors for Barrett's esophagus of any length were erosive esophagitis and hiatal hernia. Kyphosis had the highest odds ratio for the presence of LSBE (OR, 1.50; 95% CI, 1.05-1.94; p=0.033). Other predictors were hiatal hernia and the absence of Helicobacter pylori infection. Conclusion Kyphosis is a risk factor for the presence of LSBE in Japanese patients.

Medical and Biotech [MESH] Definitions
A condition with damage to the lining of the lower ESOPHAGUS resulting from chronic acid reflux (ESOPHAGITIS, REFLUX). Through the process of metaplasia, the squamous cells are replaced by a columnar epithelium with cells resembling those of the INTESTINE or the salmon-pink mucosa of the STOMACH. Barrett's columnar epithelium is a marker for severe reflux and precursor to ADENOCARCINOMA of the esophagus.
A species of FLAVIVIRUS, one of the Japanese encephalitis virus group (ENCEPHALITIS VIRUSES, JAPANESE), found in Australia and New Guinea. It causes a fulminating viremia resembling Japanese encephalitis (ENCEPHALITIS, JAPANESE).
A species of FLAVIVIRUS, one of the Japanese encephalitis virus group (ENCEPHALITIS VIRUSES, JAPANESE), which is the etiological agent of Japanese encephalitis found in Asia, southeast Asia, and the Indian subcontinent.
Vaccines or candidate vaccines used to prevent infection with Japanese B encephalitis virus (ENCEPHALITIS VIRUS, JAPANESE).
A subgroup of the genus FLAVIVIRUS which comprises a number of viral species that are the etiologic agents of human encephalitis in many different geographical regions. These include Japanese encephalitis virus (ENCEPHALITIS VIRUS, JAPANESE), St. Louis encephalitis virus (ENCEPHALITIS VIRUS, ST.
