Variability in addictive and carcinogenic potential of smokeless tobacco products marketed in Mumbai, India: a surveillance study.

Background: India has the highest incidence worldwide of smokeless tobacco (SLT)-associated oral cancer, accounting for nearly 70% of all SLT users globally. Nicotine and tobacco-specific -nitrosamines (TSNA) play critical roles in the addictive and carcinogenic potential, respectively, of SLT products. Our group has previously reported substantial variability in nicotine and TSNA levels across a small SLT product sample in India, calling for systematic surveillance.

Using Low-cost Videoscopes to Obtain Accurate Video "Oral Selfies" as Screening for HPV-associated Oropharyngeal Cancer: A New Screening Technology?

Human papillomavirus (HPV)-related oropharyngeal cancers associated with sexual contact are increasing, with high rates in men who have sex with men. HPV-related cancers have the advantage of being frequently detectable through oropharyngeal visual examination and having much higher survival rates than classic oropharyngeal cancers. It has been demonstrated that gay and bisexual men can take smartphone oropharyngeal "selfies" of sufficient quality for screening.

Fibula Free Flap Reconstruction of Cervical Spine Defects: A Multi-Institutional Study.

Introduction: Cervical spine defects result in spinal instability, putting the spinal cord and vertebral arteries at risk of damage and possibly devastating neurological injuries. The fibula free flap can span the spinal defects for stability. There is a paucity of literature on this technique.

Esophageal perforation after anterior cervical spine surgery.

Objective: To report our updated experience in the management of esophageal perforation resulting from anterior cervical spine surgery, and to compare two wound management approaches.

Methods: This is a retrospective review of patients managed for esophageal perforations resulting from anterior cervical spine surgery (2007-2020).
