BACKGROUND The risk of stroke and the long-term prognosis of recurrent strokes in young patients with patent foramen ovale (PFO) are not well known. For this reason, the treatment of these patients remains empirical. An alternative treatment to prolonged antithrombotic therapy may be surgical closure of the PFO. METHODS Thirty patients (20 men and 10(More)
OBJECTIVE To evaluate the effects of maximizing the oxygen delivery on morbidity and mortality in patients >60 yrs of age and/or with chronic diseases of vital organs who underwent major elective surgery. DESIGN Prospective, randomized, controlled trial. SETTING A 24-bed general intensive care unit of a teaching hospital. PATIENTS Thirty-seven(More)
BACKGROUND Hypertension is the major risk factor for stroke associated with small-artery disease and large-artery disease, but the factors behind the development of a particular stroke subtype in individual patients are not known. METHODS We determined risk factors potentially predictive of stroke subtype in 822 of 2760 patients consecutively admitted to(More)
Inhibitors of platelet aggregation are in use for prevention of cerebrovascular insults (CVI). Aspirin at a dose of 250 +/- 100 mg/day is the most common regimen for patients at an elevated risk for vascular complications. Aspirin and ticlopidine (500 mg/day) are the best drugs for secondary prevention of arterio-arterial cerebrovascular incidents. Efficacy(More)
Cerebrovascular disease is the 3rd leading cause of death and an important cause of hospital admission and long-term disability in most industrialized populations. Many studies have shown that brain infarct is the most frequent form of cerebrovascular disease (83%). Brain infarct is a heterogeneous entity with several etiologies (mainly large-artery(More)
In this prospective study, multiplex polymerase chain reaction (PCR) was used to identify genes encoding virulence factors (ica, atlE and mecA) in Coagulase-negative Staphylococcus (CNS) isolates from the ocular microbiota of patients undergoing cataract surgery and to investigate possible changes in the CNS profile due to antibiotic prophylaxis.

INTRODUCTION Toxoplasmosis is a worldwide disease; it can cause decreased vision or even blindness. The route of transmission in humans may vary according to the habits of the region; probably the ingestion of raw or undercooked meat is the main source of infection.
