[Multiple exposure to pesticides and impacts on health: a cross-section study of 102 rural workers, Nova Friburgo, Rio de Janeiro State, Brazil].

A cross section study was carried out in a farming community from Nova Friburgo, Rio de Janeiro state, Brazil, to examine epidemiological, clinical and laboratory aspects of multiple exposure to pesticides in a representative sample of 102 small farmers. Both males and females were submitted to an extensive protocol which included an occupation questionnaire, biological sample collection for toxicology analysis and clinical - general and neurological - evaluation. The toxicology test results showed light to moderate episodes of acute intoxication by organophosphorates either described by the farmers or observed during clinical examination.

[Interictal brain SPECT in patients with medically refractory temporal lobe epilepsy].

The objective of this study was to evaluate the utility of interictal brain SPECT in localizing the epileptogenic focus in a population of patients of Epilepsy Clinic of Hospital Universitário Clementino Fraga Filho (HUCFF/UFRJ), with medically refractory temporal lobe epilepsy (TLE) and normal computed tomography (CT) scans, studying the correlation between SPECT, electroencephalogram (EEG) and, in 11 cases, brain magnetic resonance imaging (MRI), and to compare the results to the other six literature series. Twelve (52.2%) patients presented abnormal SPECT.
