Impact of posterior septectomy on olfaction in endoscopic endonasal transsphenoidal surgery.

Background: Endoscopic endonasal transsphenoidal surgery is widely used to resect pituitary adenomas, yet its impact on olfactory function after resection of the posterosuperior nasal septum remains a concern. To optimize surgical techniques to preserve olfactory function, it is essential to understand the relationship between the extent of septal resection and olfactory outcomes.

Methods: This retrospective study analyzed 295 patients who underwent pituitary adenoma surgery.

Sinonasal Complications of Combined Transseptal-Transnasal and Bilateral Transnasal Approaches for Endoscopic Endonasal Transsphenoidal Pituitary Surgery.

Background: The endoscopic combined transseptal-transnasal technique for pituitary adenoma excision is notable for enhanced postoperative functional outcomes. Our study compared the incidence of anterior nasal septal perforation and the resulting sinonasal complications between this method and the bilateral transnasal approach.

Methods: Using a retrospective cohort from a pre-eminent tertiary referral center, we analyzed 141 cases of endoscopic endonasal transsphenoidal surgery performed between March 2018 and May 2023.

The Relationship between Seropositive Rheumatoid Arthritis and Congestive Heart Failure: A Nationwide Longitudinal Cohort Study in Korea.

The aim of this nationwide longitudinal cohort study is to determine the risk of congestive heart failure (CHF) associated with a seropositive rheumatoid arthritis (RA) population in Korea. In this study, National Health Insurance Service-Health Screening Cohort (NHIS-HEALS) data from 2002 to 2003 were used. The cohort was followed up with for 12 years until December of 2015.

A rare case of esophageal mucoepidermoid carcinoma successfully treated via endoscopic submucosal dissection.

Esophageal mucoepidermoid carcinoma (EMEC) is a special subtype of esophageal malignancy, accounting for less than 1% of all cases of primary esophageal carcinoma. Pathologically, it consists of a mixture of adenocarcinoma and squamous cell carcinoma with mucin-secreting cells. Special staining for mucicarmine helps to diagnose EMEC.

Clinicopathological analysis of non-functioning pituitary adenomas (PAs) according to the 2022 WHO classification.

Purpose: For asymptomatic non-functioning pituitary adenomas (NFPAs), conservative approaches such as observation are preferred. However, some NFPAs exhibit poor prognoses. Thus, the purpose of this study was to investigate clinicopathological characteristics of tumors for identifying those with unfavorable prognoses.
