Prognostic Effectiveness of PD-L1 Tumoral Expression in Oral Cavity Squamous Cell Carcinoma.

PD-L1 is a glycoprotein present on antigen-presenting cells and malignant cells and activates the PD-L1 receptor on cells surfaces, leading to T-cell anergy and death. The objective of this study was to assess PD-L1 tumoral expression in 50 patients with oral squamous cell carcinoma, define its prognostic value, and investigate its association with 2-year overall survival, locoregional recurrence, distant metastasis, and a number of other clinicopathological parameters. In a 24-month prospective observational study, involving 50 oral cavity squamous cell carcinoma patients, PD-L1 tumoral expression was evaluated using semiquantitative immunohistochemistry analysis by an experienced pathologist.

Alcohol-Containing Mouthwash and the Risk of Oral Cancer: Exploring the Association.

Oral cavity and larynx cancers are generally associated with tobacco consumption, alcohol abuse or both. Mouthwashes are liquid antiseptic solutions that decrease the microbial load in the oral cavity. Alcohol is often used in mouthwashes for its antiseptic functions and as a carrier for some active ingredients, including menthol or thymol, helping them penetrate the plaque.

Misconducts in research and methods to uphold research integrity.

Research misconduct refers to deliberate or accidental manipulation or misrepresentation of research data, findings, or processes. It can take many forms, such as fabricating data, plagiarism, or failing to disclose conflicts of interest. Data falsification is a serious problem in the field of medical research, as it can lead to the promotion of false or misleading information.

Endoscopic Sellar Defect Reconstruction with Avascular Modified Gasket Seal Technique for Sellar Tumors.

Watertight repair of the skull base defect is necessary during endonasal skull base surgery to avoid postoperative CSF leak (poCSFl) and consequent intracranial complications. Various techniques have been described for reconstructing sphenoid-sellar defects with varying success rates. We have described the immediate and long-term outcomes following the reconstruction of sphenoid-sellar defects with our technique.

Lower Rates of Hypocalcemia Following Near-Infrared Autofluorescence Use in Thyroidectomy: A Meta-Analysis of RCTs.

Background: Iatrogenic injury of the parathyroid glands is the most frequent complication after total thyroidectomy.

Objective: To determine the effectiveness of near-infrared autofluorescence (NIRAF) in reducing postoperative hypocalcemia following total thyroidectomy.

Methods: PubMed, Scopus, and Google Scholar databases were searched.

NLP AI Models for Optimizing Medical Research: Demystifying the Concerns.

Natural language processing (NLP) AI models have gained popularity in research; however, ethical considerations are necessary to avoid potential negative consequences. This paper identifies and explores the key areas of ethical concern for researchers using NLP AI models, such as bias in training data and algorithms, plagiarism, data privacy, accuracy of generated content, prompt and content generation, and training data quality. To mitigate bias, researchers should use diverse training data and regularly evaluate models for potential biases.

Standardizing the Head and Neck Cancer Treatment and Research.

Head and neck cancer requires a multidisciplinary approach, with standardized care being essential for consistent, high-quality treatment. Standardization involves evidence-based guidelines and protocols, and collaboration is necessary for research and improving outcomes. However, collaboration can be challenging due to various barriers.

Emergency Tracheostomy in Locally Advanced Anaplastic Thyroid Cancer.

Over 30% of cases may present with acute airway obstruction due to anaplastic thyroid cancer (ATC). In such situations, performing an emergency tracheostomy may be mandatory to save the life. A retrospective, single-centre study at our centre was conducted between 1 January 2021 to 31 December 2022.

Observational Learning in Surgical Skill Development.

Observation plays a key role in the development of surgical skills, as it allows trainees to learn from experts and improve their performance through trial-and-error practice. This process, known as motor learning, involves the creation of new neural pathways that enable precise control of surgical instruments through hand movements. In recent years, there has been a shift towards minimally invasive surgery, which requires surgeons to continually learn new motor skills to control specialized instrumentation.

Survival Outcomes in T3 Laryngeal Cancers: Primary Total Laryngectomy vs. Concurrent Chemoradiation or Radiation Therapy-A Meta-Analysis.

Background: The management of cT3 laryngeal cancers remains controversial, with studies recommending surgical or non-surgical approaches. Despite the many papers that have been published on the subject, there is a lack of studies showing which treatment has better results in terms of survival.

Objective: To determine the difference in survival outcomes following total laryngectomy (TL), concurrent chemoradiation (CRT) or radiation therapy (RT) alone in T3 laryngeal cancers.

Adenoid Morphology and Other Prognostic Factors for Otitis Media with Effusion in School Children.

Introduction: This study aimed to compare the children having enlarged adenoids with and without otitis media with effusion (OME) concerning clinical features like mouth breathing, snoring, recurrent episodes of cold, hearing impairment and specific morphology of adenoid. Further, the flora of adenoid tissue and middle ear fluid were also compared.

Methods: One hundred and twenty children having clinical features suggestive of enlarged adenoids with [Group A (n = 60)] or without [Group B (n = 60)] OME were included in this cross-sectional study.
