A systematic review of comparative studies of CO and erbium:YAG lasers in resurfacing facial rhytides (wrinkles).

Background: Laser resurfacing is used to minimize wrinkles, solar scars and sequelae of acne.

Objective: Purpose of the systematic review was to compare resurfacing outcomes of CO laser and erbium: yttrium aluminium garnet (erb:YAG) laser therapies.

Lovastatin lowers the risk of breast cancer: a population-based study using logistic regression with a random effects model.

Background: Laboratory studies have demonstrated statin-induced apoptosis of cancer cells, including breast cancer cells, and evidence is accumulating on the mechanism of statin-induced apoptosis. However, despite numerous epidemiological studies, no consensus has been reached regarding the relationship between statin use and breast cancer risk.

Methods: This retrospective case-control study enrolled 4332 breast cancer patients and 21,660 age-matched controls registered in the National Health Insurance program of Taiwan, which covers approximately 99% of the population.
