Disease knowledge, perceived risk, and health behavior engagement among adolescents and adults with congenital heart disease.

Objective: Survivors of congenital heart disease (CHD) are at risk for life-threatening complications as they age. This study aimed to examine the association of knowledge of future health risks, perceived risk, and health behaviors among adolescents and adults with CHD.

Methods: CHD survivors (N = 200, ages 15-39; 23% simple, 44% moderate, 33% complex lesions) completed measures of risk knowledge accuracy and perceived risk for developing complications, and reported physical activity and saturated fat intake.

Iron, genes, and viruses: the porphyria cutanea tarda triple threat.

Porphyria cutanea tarda (PCT) is a vesiculobulIous disorder often associated with estrogens, hepatitis C virus (HCV), alcoholism, hereditary hemochromatosis (HH), and human immunodeficiency virus. Hepcidin, a peptide hormone produced by the liver, has been associated with iron metabolism in 3 common precipitating factors for PCT: HCV, HH, and alcohol consumption. We present the case of a patient with erosions and noninflammatory bullae on his hands and forearms who received a diagnosis of PCT.

Thyroid function and autoantibody status among women who spontaneously deliver under 35 weeks of gestation.

Objective: Recent studies report an association between maternal thyroid auto-antibodies and preterm birth. None have made the important distinction between spontaneous and iatrogenic preterm birth. We investigated the association between spontaneous preterm birth before 35-week gestation and both thyroid function and auto-antibody status.
