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.

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.

Reconstructive cranial surgery for invasive and non-responsive mucormycosis.

The incidence of mucormycosis showed a sharp rise during the COVID-19 pandemic in vulnerable populations like people with diabetes. Here, we report a case of mucormycosis of the frontal and ethmoid sinuses in a man in his mid-50s with a background of diabetes mellitus and COVID-19 infection requiring steroids and oxygen support. The infection had remained persistent despite initial debridement by functional endoscopic sinus surgery of the anterior frontal sinus wall and re-exploration, followed by debridement using the brow incision.
