[Analysis of Clinical-Scientific Research on Diabetes Mellitus in Chile: A 13-Year Study].

Introduction: Chile has one of the highest prevalences of Diabetes Mellitus (DM) in Latin America. Therefore, it is relevant to conduct a scientific analysis to identify national scientific productivity in this field objectively and determine if the research efforts are directed toward clinical priorities.

Materials And Methods: A systematic review of research conducted on DM in Chile was designed.

[Antineutrophil cytoplasmic antibody (ANCA)-positive vasculitis associated to the use of propylthiouracil. Report of four cases].

Antineutrophil cytoplasmic antibody (ANCA)-positive vasculitis is an uncommon complication of the use of propylthiouracil. When it occurs, it affects multiple organs as any systemic vasculitis. We report three females and one male, aged 30, 40, 43 and 41 years respectively, that after a lapse of 12 to 28 months of propylthiouracil use, presented clinical signs of vasculitis.

[Fetal growth restriction and insulin resistance. New findings and review of the literature].

There is a strong association between low birth weight and insulin resistance. The thrifty phenotype hypothesis, which postulates fetal programming for adaptation to an adverse intrauterine environment, resulting in a lower insulin sensitivity in utero, is one of the hypothesis to explain this association. Later in life, syndrome X may develop, featuring hypertension, dyslipidemia, central obesity and type 2 diabetes, associated to an excessive food intake.
