Vitamin D deficiency and insulin resistance in obese African-American adolescents.

Objective: The study aim determined if low 25-hydroxy vitamin D levels correlated with low levels of adiponectin and insulin resistance in African American adolescents with body mass index > or = 85th %.

Patients And Methods: Fasting blood levels of adiponectin, 25-hydroxy vitamin D, insulin, glucose, lipid, leptin and glycosylated hemoglobin were measured in a total of 34 (19 study and 15 control) African American adolescents between the ages of 10 and 20 years. Nutritional vitamin D intake and body composition measurements were assessed.

Interrelationship between thyroid nodularity and TSH level.

Background: The pathophysiological role of thyroid-stimulating hormone (TSH) in the development of goiter is controversial. The aim of this study was to examine the relationship between thyroid nodularity and serum TSH levels in clinically and biochemically euthyroid patients with non-endemic multinodular goiter.

Methods: We surveyed 44 of our endocrine clinic patients with multinodular goiter.
