Rosacea: a common, yet commonly overlooked, condition.
Rosacea is a common, but often overlooked, skin condition of uncertain etiology that can lead to significant facial disfigurement, ocular complications, and severe emotional distress. The progression of rosacea is variable; however, typical stages include: (1) facial flushing, (2) erythema and/or edema and ocular symptoms, (3) papules and pustules, and (4) rhinophyma. A history of exacerbation by sun exposure, stress, cold weather, hot beverages, alcohol consumption, or certain foods helps determine the diagnosis; the first line of treatment is avoidance of these triggering or exacerbating factors. Most patients respond well to long-term topical antibiotic treatment. Oral or topical retinoid therapy may also be effective. Laser treatment is an option for progressive telangiectasis or rhinophyma. Family physicians should be able to identify and effectively treat the majority of patients with rosacea. Consultation with subspecialists may be required for the management of rhinophyma, ocular complications, or severe disease. (Am Fam Physician 2002;66:442.)
Patients' understanding and use of snack food package nutrition labels.
PURPOSE: Little information exists on how patients in medical practice use food package nutrition labels. We theorized that patients in a general medical practice might not make the distinction between serving size and total package nutrition information, and this might lead to obesity. METHODS: Ninety patients between ages of 18 and 65 attending the St. Francis/University of Tennessee Family Practice Center were interviewed to determine whether they could calculate the total calories in sample snack food packages that contained more than one serving. RESULTS: Ninety percent of our patient sample correctly identified the number of calories per individual serving, but only 37% were able to recognize that the sample packages contained multiple servings. Confusion between calories per serving size and total calories per package was correlated with lower educational levels (P =.011) and with the presence of cardiovascular heart disease in our patient sample. CONCLUSIONS: Our patients tended to think of a multiple serving package as one serving. They underestimated and under-reported caloric intake from snack food sources. We conclude that snack food labels as actually used by patients do not lead to informed dietary choices. These findings could impact our understanding and management of the obesity epidemic in the United States.
