[Pseudobulbar affect in stroke patients in Argentina].

Background: Pseudobulbar affect is defined by involuntary or exaggerated episodes of laughter or crying, subsequent to a specific disease. After-stroke pseudobulbar affect is reported in 11%-34% of patients. In our population is underdiagnosed.

Cerebral venous thrombosis in Argentina: clinical presentation, predisposing factors, outcomes and literature review.

Background: Cerebral venous thrombosis (CVT) is a rare medical condition that primarily affects young adults. The clinical spectrum is broad and its recognition remains a challenge for clinicians. Limited information is available on CVT in Argentina.

Everything you always wanted to know about sex and Neurology: neurological disability and sexuality.

Objective: Chronic neurological disorders generate disabilities affecting multiple aspects of life, including sexuality.

Objective: To describe the presence of sexual dysfunction and comorbidities in a population with chronic neurological disorders. To analyze the relationship between disability and sexual dysfunction.

Activated protein C resistance in patients with arterial ischemic stroke.

Background: Activated C protein resistance (APC-R) has recently been reported to be a common cause of thrombophilia; it may be acquired or caused by a genetic defect (factor V Leiden mutation). It is clear that there is an association between APC-R and venous thrombosis. It has been suggested that there is a possible relationship of APC-R with arterial ischemic stroke (IS), but case-control studies have not given enough clues for considering APC-R as a main risk factor.

Southern Buenos Aires stroke project.

Background: Ethnic differences and vascular risk factors are the major determinants of stroke subtypes. Nevertheless, specific data from undeveloped countries is difficult to obtain. Natives from South America may have a higher frequency of penetrating small vessel disease and hemorrhagic stroke.

Multiple simultaneous intracerebral hemorrhages: clinical features and outcome.

Background: The simultaneous occurrence of intracerebral hemorrhages in different arterial territories is an uncommon clinical event. Its predisposing factors and pathophysiological mechanisms are not clearly defined.

Objective: To analyze the frequency, risk factors, clinical features, neuroimaging findings, and outcome of multiple simultaneous intracerebral hemorrhages (SIHs).

[Fluctuation in bilateral thalamic infarction: diffusion study using magnetic resonance].

Introduction: Bilateral paramedian thalamic infarcts are uncommon. The most frequent clinical manifestations are acute impairment of consciousness, oculomotor abnormalities and cognitive disturbances. A fluctuating course has not been previously reported.

Differences in stroke subtypes among natives and caucasians in Boston and Buenos Aires.

Background And Purpose: Several issues regarding ethnic-cultural factors, sex-related variation, and risk factors for stroke have been described in the literature. However, there have been no prospective studies comparing ethnic differences and stroke subtypes between populations from South America and North America. It has been suggested that natives from Buenos Aires, Argentina, may have higher frequency of hemorrhagic strokes and penetrating artery disease than North American subjects.

[Cerebral embolism of cardiac origin].

We reviewed 538 charts of patients hospitalized with acute ischemic strokes between 1983 and 1991. The inclusion criteria for cardioembolism were: 1) sudden onset and maximal neurological focal deficit from the beginning, 2) brain CT showing an ischemic infarct, hemorrhagic infarct, or multiple infarcts, 3) cardioembolic sources demonstrated by echocardiography or heart catheterization, and 4) absence of stenotic-occlusive cerebrovascular disease. Sixty-nine patients (12.
