Article Synopsis
  • The study aimed to assess medical students' views on the transition to pass/fail scoring for the USMLE Step 1 exam and its impact on anxiety, especially regarding applications to competitive specialties.
  • A survey was conducted among Penn State College of Medicine students, revealing that while most (73.2%) supported the pass/fail system, anxiety about Step 2 scores increased, particularly among those applying to competitive specialties.
  • The results indicated a notable difference in perceived matching chances for competitive versus non-competitive specialties, with significant implications for how students view key components of residency applications, such as letters of recommendation.

Article Synopsis
  • - The study aims to assess tobacco usage documentation, including electronic nicotine delivery systems (ENDS), among otolaryngology patients to help reduce head and neck cancer incidence and improve recovery outcomes.
  • - Analyzing data from over 2,100 adult patients, the research found that 56.7% were never smokers, 28.9% were former smokers, and 14.4% were current smokers, with a significant majority of current users relying on cigarettes.
  • - Results highlight that certain demographics, such as males, unmarried individuals, uninsured patients, and those with head and neck cancers, showed higher rates of tobacco use, suggesting a need for better documentation and intervention strategies in clinical settings.

Background: Differences in treatment outcomes between community or academic centers are incompletely understood.

Methods: Retrospective review of head and neck cancer patients between 2010 and 2020 in a rural health region. Kaplan-Meier curves and log-rank tests were used to evaluate survival outcomes, along with bivariate and multivariable Cox proportional hazards models.

Objective: The purpose of this study is to evaluate the postoperative urinary complications and the optimal timing of foley catheter removal in patients who underwent free flap reconstructive surgery for head and neck pathology.

Methods: A retrospective case-control study of head and neck patients who underwent free flap reconstructive surgery at a single institution between January 2009 and December 2021 was conducted. Patient risk factors for postoperative urinary retention (POUR) were analyzed.

Background: Several studies have demonstrated varying rates of efficacy, reliability, and sensitivity of sentinel lymph node biopsy (SLNB) in identifying occult nodal disease for early stage oral cavity squamous cell carcinoma (OCSCC) depending on the radionuclide agent utilized. No head-to-head comparison of cost or clinical outcomes of SLNB when utilizing [Tc]tilmanocept versus [Tc]sulfur colloid has been performed. The goal of this study was to develop a decision model to compare the cost-effectiveness of [Tc]tilmanocept versus [Tc]sulfur colloid in early stage OCSCC.

Article Synopsis
  • The American Head and Neck Society (AHNS) developed a position statement with treatment recommendations for using PD-1 inhibitors in advanced cutaneous squamous cell carcinoma (cSCC) and identified areas needing more research.
  • A literature search was conducted using various databases to create evidence-based statements, which were then evaluated for consensus among AHNS members using Delphi methodology.
  • The final consensus included 26 statements, highlighting knowledge gaps like the effects of immunosuppression on cSCC treatment and the use of PD-1 inhibitors in immunosuppressed patients.*

The immunosuppressed (IS) population encompasses a diverse cohort of patients to include iatrogenically immunocompromised organ transplant recipients as well as patients with chronic lymphoid malignancies, human immunodeficiency virus/acquired immunodeficiency syndrome, and autoimmune disorders. Cutaneous cancers in this high-risk patient group are clinically distinct from the general immunocompetent population, showing aggressive behavior with associated poor outcomes. This article reviews the pathogenesis, epidemiology, incidence, prognosis, and special considerations required in managing cutaneous cancers in the IS patient population.

Objectives: To evaluate the incidence of histopathologic diagnostic discrepancy for patients referred to our institution, identify pathologies susceptible to diagnostic error, and assess the impact on survival of histopathologic diagnostic discrepancies.

Methods: Three hundred ninety-seven patients with sinonasal cancers were identified, and discordance between the outside pathologic report and MD Anderson Cancer Center pathologic report was assessed. Overall survival and disease-specific survival were analyzed using Kaplan-Meier and log rank methods.

The coronavirus disease-2019 (COVID-19) pandemic has rapidly spread across the world, placing unprecedented strain on the health care system. Health care resources including hospital beds, ICUs, as well as personal protective equipment are becoming increasingly rationed and scare commodities. In this environment, the laryngectomee (patient having previously undergone a total laryngectomy) continues to represent a unique patient with unique needs.

Background: The 8th edition of the American Joint Committee on Cancer's (AJCC) staging system for oral cavity cancer incorporates pathological features. We aimed to assess whether these changes results in better risk stratification of patients with early oral tongue squamous cell carcinoma (OTSCC).

Methods: Overall survival (OS) and disease-specific survival (DSS) of 244 patients were calculated using the Kaplan-Meier method.

Cavernous sinus thrombosis is a rare but well-documented complication of sinus disease, propagated by intracranial spread of infection via valveless veins of the midface, with facial cellulitis as an uncommon source of infection. We present a case of significant intracranial thromboses secondary to nasal dorsal abscess after trauma that was successfully treated with bedside drainage of the abscess in addition to broad-spectrum antibiotics, anticoagulation, and steroids, and remains asymptomatic with seven months follow-up.
