Sinonasal undifferentiated carcinomas (SNUCs), being an aggressive malignancy with dismal survival outcome, have given limited consideration regarding management of regional failures. A total of 12 studies, published between 1999 and 2019, met inclusion criteria. We performed a meta-analysis assessing regional (neck) relapse after elective neck treatment compared to observation in clinically node negative (N0) necks. Clinical data of 255 patients were used for meta-analysis. Among them, 83.4% of patients presented with T4 tumors and 14.1% had positive neck nodes. Elective neck treatment was applied in 49.5% of analyzed patients. Regional relapses occurred in 3.7% of patients who have undergone elective neck treatment compared to 26.4% in patients who had not. Elective neck treatment significantly reduced the risk of regional recurrence (odds ratio 0.20; 95% confidence interval 0.08-0.49; P = .0004). The meta-analysis indicates that elective neck treatment could significantly reduce the risk of regional failures in patients with SNUCs.

Cervicothoracic Emphysema After Nasotracheal Intubation Attempt: A Life-Threatening Complication-A Case Report.
A A Pract
January 2025
From the Departments of Anesthesiology.
Nasotracheal intubation is a commonly used technique in elective oral and pharyngeal surgeries. This case report details an incident involving a young adult patient in which an attempt at nasotracheal intubation resulted in a life-threatening cervicofacial and thoracic emphysema. Although complications associated with nasotracheal intubation are rare, their potential severity necessitates a comprehensive preprocedural discussion and risk assessment with the surgical team to confirm its appropriate indication for each individual patient.

Purpose: The main objective of this study was to assess the impact of a composite quality improvement intervention on mode of birth in nullipara term singleton vertex (NTSVs).
Material And Methods: This was an ambidirectional study following the implementation of the intervention to reduce cesarean section rate in NSTV by comparing two birth cohorts, pre-composite quality improvement intervention cohort (January 2013-December 2015) and post-composite quality improvement intervention cohort (January 2018-December 2020).
Results: In the studied periods, there was a total of 7713 NTSV births.
