The clinical spectrum of retroperitoneal hematoma in anticoagulated patients.

Bleeding into the retroperitoneal space is a serious complication of anticoagulation. The incidence may be on the rise due to the increasing number of patients prescribed anticoagulants for atrial fibrillation and other disorders. The clinical manifestations vary from leg paresis to abdominal pain or a catastrophic shock.

[Risk factors and stroke among patients of different ages].

Objective: To determine the frequency of cardiovascular risk factors in patients of different ages with ischemic cerebrovascular accident.Patients and methods. Descriptive, retrospective study of 1,077 patients with stroke or transient ischemic attack.

Atrial fibrillation as a risk factor for stroke recurrence.

Background: Although atrial fibrillation is a well-known risk factor for ischemic stroke, the extent to which it increases the risk of stroke recurrence, particularly in elderly patients, is less certain.

Methods: We performed a retrospective cohort study of 915 patients aged 50 to 94 years who were admitted with an ischemic stroke. The rates of recurrent strokes and recurrent severe strokes were estimated with the Kaplan-Meier method.

[Abscess of the psoas muscle. Description of a series of 23 cases].

Background: Abscess of the psoas muscle (PA) is an infrequent disease of difficult diagnosis. During the last decade, the number of cases has increased because of the raising use of radiology tecniques: ecography, computerized tomography and magnetic resonance nuclear.

Methods: The presentation and management of psoas abscess was studied retrospectively in 23 patients from 1992 2000.
