To differentiate acute purulent tonsillitis from infectious mononucleosis, divide the total number of lymphocytes by the WBC count. If the ratio is >0.35, the diagnosis is mono.

Women face extra antibiotic risks

Should women of childbearing age who require antibiotics be advised that such medications may decrease the effectiveness of oral contraceptives (OCs) and therefore, they should abstain or use a backup method? Also, am I correct to assume that a negative beta human chorionic gonadotropin (β-hCG) test is advised prior to starting isotretinoin (which is teratogenic)?—Dean…
