Extraosseous Ewing sarcoma in the fossa jugular: A rare case report.

Background: Extraosseous Ewing sarcoma (EES) is a rare case that accounts for 20% of Ewing sarcoma cases. EES is the second most prevalent pediatric malignancy after peripheral primitive neuroectodermal tumors. EES mostly arise from soft tissue and extra-skeletal.

Correlation between blood urea nitrogen level and cochlear outer hair cell function in non-dialysis chronic kidney disease patients.

Background: Hearing loss due to impaired cochlear function, which results from increased blood urea nitrogen (BUN) level, is one of the important clinical problems in chronic kidney disease (CKD) patients with uremia. This study aims to determine correlation between blood urea nitrogen (BUN) levels and cochlear Outer Hair Cell (OHC) dysfunction in non-dialysis stage 3-5 CKD patients so that the BUN levels may also be used to determine the presence of cochlear OHC dysfunction.

Design And Methods: An observational analytic study with a cross sectional design and consecutive sampling.
