* Non-genital wart therapies such as cryotherapy, fluorouracil and pulsed dye lasers are ineffective, says a new study. Only those that use salicylic acid have evidence of efficacy. Since all wart cures can cause irritation and toxic side-effects, doctors suggest that patients not bothered by their wart may be better off letting it clear on its own (BMJ, 2002; 325: 461-4).
* Women are more prone to oxidative damage than men. Say the researchers, their findings suggest that women may need a higher intake of antioxidants like vitamin C, and fresh fruit and vegetables, than men to stay healthy (Am J Epidemiol, 2002; 156: 274-85).
* Chest pain is a tell-tale sign of a heart attack, but it's not the only one. In a recent five-year study, nearly half the patients had 'atypical' symptoms such as shortness of breath, cardiac arrest, dizziness, weakness or fainting, abdominal pain and other symptoms (Ann Emerg Med, 2002; 40: 180-6).
