A comprehensive review article by Stephen S. Hecht summarizes the biochemistry, biology, and carcinogenicity of tobacco-specific nitrosamines, linking them to lung cancer formation. The article highlights the importance of understanding these compounds for developing effective chemoprevention strategies and targeted prevention methods.
A study challenges the widely accepted pediatric practice of prescribing a 10-day course of antibiotics for uncomplicated ear infections, suggesting that five days of short-acting oral antibiotics are equally effective.
