Histological Inflammation in the Endoscopically Uninflamed Mucosa is Associated With Worse Outcomes in Limited Ulcerative Colitis.

Background: The Montreal classification categorizes patients with ulcerative colitis (UC) based on their macroscopic disease extent. Independent of endoscopic extent, biopsies through all colonic segments should be retrieved during index colonoscopy. However, the prognostic value of histological inflammation at diagnosis in the inflamed and uninflamed regions of the colon has never been assessed.

DFNB1-associated deafness in Portuguese cochlear implant users: prevalence and impact on oral outcome.

Objectives: Hearing loss is a condition that interferes with the development of the child at a cognitive and language level. Therefore, early diagnosis of deafness is important for (re)habilitation, namely through the use of cochlear implant (CI). The present study aimed at screening CI Portuguese individuals for the presence of mutations in the genes GJB2 and GJB6 (DFNB1 locus), and searching a possible correlation between the genotype and the oral habilitation outcome following implantation.
