This study identifies several patient and physician factors associated with treatment preference and related outcomes in patients being treated for AK.

To determine the most frequently diagnosed conditions among rural and non-rural children age 5 to 9 and assess for environmental influences, data from the National Ambulatory Medical Care Survey (1996-2001) were used to examine frequencies of diagnoses in children age 5 to 9. Separately, we examined rural and non-rural outpatient physician visits in weighted multivariate logistic regression models. Overall, the most frequent diagnosis was routine health check, followed by several acute conditions. When analyzed separately, non-rural children were significantly more likely to visit a physician for routine health check (P = 0.002), asthma (P = 0.005), and acute upper respiratory infection (P = 0.037). Rural counterparts were significantly more likely to be seen for attention deficit disorder (P = 0.000), otitis media (P = 0.017), chronic rhinitis (P = 0.017) and influenza (P = 0.037). Children age 5 to 9 are healthy overall. When illness occurs, it is usually acute. Rural and non-rural, young, school-aged children exhibit many similarities in healthcare utilization, but differences occur. Most surprising is the difference in the diagnosis frequency of attention deficit disorder.

There is a race-related differential in the treatment of pigmentary skin disorders, with non-white patients having a probability of receiving more care for these conditions in US outpatient settings. This lends support to our hypothesis that darker pigmentation in non-white populations is the driver of a differential in the utilization of pigmentation-related skin visits.

DM is associated with significantly increased cutaneous blood flow, even at sites where no erythema is evident. This suggests significant involvement of the skin vasculature in this disease process.
