Smoking cessation or reduction leads to fewer wound-related and cardiovascular complications, with a significant decrease in hospital stay duration.
A prospective population study found that HIV-1-positive women are 16 times more likely to develop vulvovaginal or perianal lesions than HIV-1-negative women. The study suggests that HIV-1-positive women should have a thorough inspection of the vulva and perianal region during gynaecological examination.
