Background: Hearing loss significantly affects children's lives; however, the health-related quality of life (QoL) of children with this disability is not well measured. We sought to develop a reliable and valid measure of health-related QoL in children with hearing loss.
Methods: We constructed a conceptual framework to assess the QoL of children with hearing loss based on the Pediatric Quality of Life Inventory™ Version 4.
Objective: To introduce the WHO 2000 diagnostic criteria of biopsy of colorectal intraepithelial neoplasia and carcinoma and to enhance diagnostic accuracy and avoid overdiagnosis and underdiagnosis.
Method: The postoperative pathological examination and preoperative biopsy in 56 patients diagnosed as colorectal intraepithelial neoplasia and carcinoma before operation from January 2001 to October 2005 were compared retrospectively.
Results: Among the 56 cases, 16 patients were diagnosed by preoperative biopsy as carcinoma in situ, intramucosal carcinoma and adenocarcinoma, but according to the new standard, of them 14 cases should be revised to be higher grade colorectal intraepithelial neoplasia.
