Analysis of risk factors for radiation-induced oral mucositis for nasopharyngeal carcinoma and prognostic value of EGF and STREM-1.

Background: This study analyzed the risk factors of radiation-induced oral mucositis (RIOM) for nasopharyngeal carcinoma (NPC) and the correlation between epidermal growth factor (EGF), soluble myeloid cell expression trigger receptor-1 (sTREM-1), and disease severity.

Methods: A total of 124 patients with NPC who received radiotherapy from March 2013 to November 2016 were enrolled and divided into the study group (n=68) and the control group (n=56) regarding the presence of RIOM. The risk factors of RIOM were evaluated by multivariate logistic regression.

Treatment of congenital middle ear cholesteatoma in children using endoscopic and microscopic ear surgeries: a case series.

Introduction: Surgical removal is widely employed in children with congenital middle ear cholesteatoma (CMEC). Here, we report the surgical outcomes of CMEC removal via endoscopic ear surgery (EES) and microscopic ear surgery (MES) in children.

Methods: Children with CMEC who underwent preoperative medical history inquiry, hearing test, endoscopic evaluation, and radiology imaging before receiving EES or MES were included.
