[Prognostic value of serum homocysteine levels in elderly hospitalized patients].

Background And Objectives: Increased serum homocysteine levels are related to vascular disease and increased mortality. The decrease of homocysteine is also associated with a worse prognosis in patients on hemodialysis; however, this relationship has not been well studied in other patients. Our goal is to study the prognosis of increased and decreased serum homocysteine levels in elderly patients admitted to a general internal medicine unit.

[Vascular risk factors and retinal occlusive disease].

Background And Objective: The aim of the present study is to define the risk factors associated with different retinal occlusive diseases, such as retinal venous thrombosis, arterial emboli and ischaemic anterior optic neuritis. Patients with any of these entities entered the study.

Patients And Method: A cross-sectional study on 284 consecutive subjects, aged 25-93, who were initially attended at the ophthalmology unit and then sent to the internal medicine unit.
