Background: Human papillomavirus (HPV) is a crucial prognostic factor in oropharyngeal cancer (OPC). p16 is a surrogate marker for diagnosing HPV+ OPC, however it is not direct evidence of HPV existence.
Objective: The purpose of our study was to evaluate an HPV DNA test-Cobas HPV assay-in diagnosing HPV+ OPC through neck lymph node aspiration.
Objectives: In early-stage oral squamous cell carcinoma (OSCC) patients, whether the margin-to-depth-of-invasion ratio (MDR) can assist in stratifying the prognosis remains unclear.
Methods: Patients diagnosed with early stage OSCC at National Taiwan University Hospital between January 2007 and December 2021 were reviewed. Patients with margin > 1 mm were classified into two groups: MDR < 0.
Article Synopsis
- The study focused on oral squamous cell carcinoma (OSCC) patients with single-node metastasis (Ns) and how the presence of extranodal extension (ENE) affects their survival outcomes.
- Among 311 reviewed patients, those with ENE had worse survival rates than those without, but larger lymph nodes (LN >3 cm) significantly increased the likelihood of having ENE.
- Postoperative radiotherapy (PORT) was found to improve regional control in both Ns patient groups, and after accounting for ENE status, the survival chances became more aligned between N category and N/N category patients.
Evolution of pediatric vertigo/dizziness during the past two decades.

Background: Increasing life expectancy and declining birth rate are two key drivers of population aging globally, resulting in a falling population.
Objective: This study investigated the evolution of pediatric patients with vertigo/dizziness during the past two decades.
Methods: From 2001 to 2010, a total of 17,123 new patients with vertigo/dizziness visited our neurotological clinic.
The development of visible-light-driven polymeric g-C₃N₄ is in response to an emerging demand for the photocatalytic dye degradation and reduction of hexavalent chromium ions. We report the synthesis of g-C₃N₄ from urea treated with various solvents such as methanol, ethanol, and ethylene glycol. The samples were characterized and the Williamson⁻Hall method was applied to investigate the lattice strain of the samples.

- Solar-driven photocatalysis using graphitic carbon nitride (g-C N ) is a promising method for hydrogen generation, breaking down organic pollutants, and reducing carbon dioxide, but bulk g-C N has limitations like low surface area and fast charge recombination that hinder its efficiency.
- The development of 3D porous hydrogels from g-C N through nanostructural engineering offers a cost-effective way to enhance its photocatalytic performance by improving adsorption, stability, and charge transfer.
- This minireview discusses recent advancements in g-C N -based hydrogels for water splitting and dye degradation, exploring synthesis methods and future challenges in their application as efficient photocatalysts.
