Serum free triiodothyronine (T3) to free thyroxine (T4) ratio in treated central hypothyroidism compared with primary hypothyroidism and euthyroidism.

Unlabelled: The standard treatment of hypothyroidism (central and primary) consists of thyroxine (T4) administration alone. However, the normal thyroid gland produces a small proportion of triiodothyronine (T3) directly into the circulation.

Aim: We aimed to study the free T3 to free T4 ratio in treated central hypothyroidism compared with euthyroidism and treated primary hypothyroidism.

[Coronary risk assessment in subjects with type 2 diabetes mellitus. General population-based scores or specific scores?].

Coronary risk in patients with type 2 diabetes mellitus can be calculated using population-based scores or diabetes-specific scores. Our objective was to compare the results with both scores in a group of patients with type 2 diabetes and no history of cardiovascular disease. We analyzed the results for 101 patients aged 40 to 65 years with type 2 diabetes and no prior cardiovascular disease.
