Microvascular complications and risk factors in patients with type 2 diabetes.

Aim: To conduct a prospective study in patients with type 2 diabetes mellitus (T2DM) with no microvascular complications, analyzing the association between various baseline risk factors and development of microvascular complications at follow-up.

Methods: A prospective, observational study in 376 patients with T2DM enrolled in 2004. The clinical end-point was urinary albumin excretion (UAE) > 30mg/24h and/or presence of retinopathy at follow-up in 2007.

Long-term outcome in 215 children and adolescents with papillary thyroid cancer treated during 1940 through 2008.

Background: Controversy exists regarding the aggressiveness of initial therapy in childhood papillary thyroid cancer (PTC). Few studies with long-term outcome exist and second primary malignancies have rarely been analyzed.

Methods: We studied 215 PTC patients younger than 21 years old managed during 1940 through 2008.

Papillary thyroid microcarcinoma: a study of 900 cases observed in a 60-year period.

Methods: Nine hundred PTM patients had initial treatment at Mayo Clinic during 1945-2004. Mean follow-up was 17.
