Sympathetic nervous system activation, antivenin administration and cardiovascular manifestations of scorpion envenomation.

Unlabelled: We performed two-dimensional echocardiograms and determined plasma norepinephrine levels on admission and at 24h after hospitalization, in 16 children with scorpion envenomation. All patients came from areas where scorpions have been identified as Tityus zulianus and received antivenin at the site of the accident or upon admission. Based on the presence or absence of cardiovascular manifestations, patients were divided into two groups.

[Effect of budesonide on bone density and metabolism in asthmatic children].

Objective: To assess the effect of inhaled budesonide on the mineral density, content and bone metabolism in children with asthma.

Material And Methods: From September 1996 to July 1997, a cross-sectional study was conducted in 38 prepubertal children aged 6 to 11 years, selected from the pediatric chest outpatient clinic of the Instituto Autónomo Hospital Universitario de Los Andes, Mérida, Venezuela. Three study groups were assembled: 9 asthmatic children treated with inhaled budesonide (300 micrograms/day) for over 6 months (Group A); 14 asthmatic children not treated with inhaled corticosteroids (Group B); and 15 non-asthmatic children (Group C).
