Acne is a multifactorial disease of the pilosebaceous unit in the skin. Four contributing pathogenic factors need to be elucidated and include excess sebum production, follicular hyperkeratinization, colonization of the pilosebaceous unit by Propionibacterium acnes.
Rosacea is relatively common, typically occurring in individuals of Northern European and Celtic origin between 30 and 50 years of age. It is more common in women, but may be more severe in men. Currently there is no cure available for rosacea, but it can be controlled with topical and oral drug therapy.
Chronic palmoplantar pustular psoriasis is a disabling condition characterized by recurrent crops of sterile pustules on a background of erythema, fissuring and scaling. Genetic and environmental factors have been implicated in its etiology.
Oral contraceptives (OCs) can reduce acne by lowering the production of adrenal and ovarian androgens, by inhibiting 5- alpha-reductase, which in turn, reduces the levels of dihydrotestosterone, and by stimulating sex hormone binding globulin (SHBG), thus reducing the levels of free testosterone.
Treatment objectives and pharmacoeconomic considerations are important when developing guidelines that are effective and rational. Canadian Acne Treatment Guidelines were last published in 1995. New guidelines were recently developed to incorporate therapeutic advances and data from more recent studies.
Antibiotic prophylaxis aims to prevent wound infections and provide adequate antibiotic cover for patients with prostheses or at risk for endocarditis. Most recommendations are based spread of risk factors may not accurately predict the risks for patients. A case for prophylaxis is made.
Benzoyl peroxide 5% plus erythromycin 3% (Benzamycin. gel, Dermik) will be evaluated. Although it is not known how effective it is compared with benzoyl peroxide and erythromycin prescribed separately, Benzamycin® is simpler to use and likely to improve patient compliance.
