Cervical lordosis in asymptomatic individuals: a meta-analysis.

Background: Cervical lordosis has important clinical and surgical implications. Cervical spine curvature is reported with considerable variability in individual studies. The aim of this study was to examine the existence and extent of cervical lordosis in asymptomatic individuals and to evaluate its relationship with age and gender.

Molecular analysis in combination with iodine staining may contribute to the risk prediction of esophageal squamous cell carcinoma.

Purpose: Mucosal iodine staining has improved the detection of precancerous lesions of the esophagus. However, this method is unable to exactly evaluate the risk status of the lesions. In the present study, we conducted a molecular analysis combining the iodine staining in esophageal squamous cell carcinomas (ESCC) and different premalignant lesions of the esophagus in order to improve the early diagnosis of ESCC.

A novel region of deletion on 13q33-q34 in esophageal squamous cell carcinoma.

Chromosome 13 presents frequent allelic loss in esophageal squamous cell carcinomas (ESCC). However, no ESCC suppressor gene has been identified from this chromosome. To define common deletion regions that possibly contain the ESCC suppressor gene(s), we performed a mapping of allelic loss in 50 esophageal squamous cell carcinomas using a panel of 25 microsatellite markers on chromosome 13q21-qter, which has rarely been studied for allelic loss.
