Serum ferritin as a component of the insulin resistance syndrome.

Objective: In epidemiological studies, serum ferritin was the second-strongest determinant of blood glucose (after BMI) in regression models and the third-strongest determinant of serum insulin (after BMI and age). Its concentration also correlated positively with plasma triglycerides and apolipoprotein B concentrations, and negatively with HDL2 cholesterol. We hypothesized that serum ferritin could be a marker of insulin resistance.

[Clinical, radiologic, ophthalmologic, and endocrine studies in the primary empty sella turcica syndrome (author's transl)].

The clinical, radiologic, ophthalmologic, and endocrine features of nine patients with the syndrome of primary empty sella turcica are described. Pneumoencephalography was diagnostic in the eight patients in whom it was performed, while the remaining case was diagnosed by computerized axial tomography. In two patients alterations of the visual fields were found, while another had a hypertensive eye fundus.
