Prognostic Factors in Head and Neck Cancer: A Retrospective Cohort Study of 3052 Patients in Brazil.

Objective: Evaluate the sociodemographic, clinical, and lifestyle characteristics at head and neck squamous cell carcinoma (HNSCC) diagnosis and their impact on overall survival (OS) across different anatomical sites.

Materials And Methods: A retrospective cohort study (2011-2021) at Instituto do Câncer do Estado de São Paulo, involving 3052 HNSCC patients. Survival analyses utilized the Kaplan-Meier method and Cox proportional hazard ratios with 95% confidence intervals, incorporating significant variables from univariate analysis.

Evaluation of the Participation of Brazilian Women in Research in Oral Pathology and Oral Medicine.

Background: Despite recent advancements, women still encounter significant challenges in various fields, including dentistry. However, the increasing interest in female participation in science acknowledges its fundamental role in the advancement of knowledge. This study aims to assess indicators of women's involvement in Brazilian research in the areas of Oral Pathology and Oral Medicine.

Deep Convolutional Neural Network for Accurate Classification of Myofibroblastic Lesions on Patch-Based Images.

Objective: This study aimed to implement and evaluate a Deep Convolutional Neural Network for classifying myofibroblastic lesions into benign and malignant categories based on patch-based images.

Methods: A Residual Neural Network (ResNet50) model, pre-trained with weights from ImageNet, was fine-tuned to classify a cohort of 20 patients (11 benign and 9 malignant cases). Following annotation of tumor regions, the whole-slide images (WSIs) were fragmented into smaller patches (224 × 224 pixels).

Development and Evaluation of a Convolutional Neural Network for Microscopic Diagnosis Between Pleomorphic Adenoma and Carcinoma Ex-Pleomorphic Adenoma.

Aims: To develop a model capable of distinguishing carcinoma ex-pleomorphic adenoma from pleomorphic adenoma using a convolutional neural network architecture.

Methods And Results: A cohort of 83 Brazilian patients, divided into carcinoma ex-pleomorphic adenoma (n = 42) and pleomorphic adenoma (n = 41), was used for training a convolutional neural network. The whole-slide images were annotated and fragmented into 743 869 (carcinoma ex-pleomorphic adenomas) and 211 714 (pleomorphic adenomas) patches, measuring 224 × 224 pixels.

Head and Neck Cancer in Pan-American Notable People: An International Survey.

The study of notable people as advocates for raising cancer awareness began in the latter decades of the 20th century. This research aimed to identify Pan-American notable people with head and neck cancer (HNC) and to explore senior health professionals' perspectives on communicating stories of notable patients with HNC to promote prevention. A cross-sectional survey was conducted using an online questionnaire designed in REDCap and administered to 32 senior health professionals with long-standing academic and clinical backgrounds in HNC.

Underexplored Areas of Photobiomodulation in Oral Oncology: An Expert Analysis.

This study aimed to review the current body of literature on underexplored areas of photobiomodulation (PBM) for preventing and/or treating oral adverse events. Recent studies suggest that PBM may offer potential benefits in managing cancer-related toxicities other than oral mucositis. Nevertheless, further research to establish conclusive evidence is still missing.

Mapping oral medicine (stomatology) and oral and maxillofacial pathology international organizations: a scoping review of global data and historical analysis.

Objectives: To describe the historical evolution and dissemination of the Oral Medicine and Oral and Maxillofacial Pathology international societies and associations across the globe, and to provide insights into their significant contributions toward oral health promotion.

Study Design: This review was conducted in accordance with the JBI Scoping Review Methodology Group guidance. The reporting followed the Preferred Reporting Items for Systematic Reviews extension for Scoping Reviews (PRISMA-ScR).

Local anesthesia nerve block for managing burning mouth syndrome: a scoping review.

Objective: To assess the clinical scenarios in which nerve blocks are employed in the context of burning mouth syndrome (BMS).

Study Design: This scoping review followed the PRISMA-ScR. A protocol was generated on Open Science Framework.

Oral leukoplakia and erythroplakia in young patients: a southern Brazilian multicenter study.

The objective of the present study was to investigate the frequency of oral leukoplakia and oral erythroplakia among young patients from three Brazilian reference centers in Oral and Maxillofacial Pathology. A retrospective study was carried out from 2011 to 2021 on 861 patients diagnosed with oral leukoplakia and oral erythroplakia. Demographic and clinicopathological data were evaluated.

Conspiracy of Silence in Head and Neck Cancer Diagnosis: A Scoping Review.

Cancer disclosure represents a complex healthcare dynamic. Physicians or caregivers may be prompted to withhold diagnosis information from patients. This study aims to comprehensively map and synthesize available evidence about diagnosis nondisclosure regarding head and neck cancer (HNC) patients.
