Clinical Trial
[Frequency of allergens in immediate, late, and dual allergic skin response at the National Institute of Pediatrics].
We studied 126 children with allergic illness in Instituto Nacional de Pediatria. We applied cutaneous test to determine the early, late and dual response. ⋯ Approximately the third part of the children studied presented late cutaneous response (dual response more isolated late response). It is important to make the evaluation of the late response in patients with allergy disease for a good etiologic diagnosis.

Randomized Controlled Trial Comparative Study Clinical Trial
[Premedication for the prevention of adverse reactions to ionic iodized contrast media. Comparative study].
A study comparing two pretreatment protocols to prevent adverse reactions to iodinated radiocontrast media (IRCM) was performed in 45 adults patients. They followed inclusion and exclusion criteria. Pretreatment protocol A was within 12 hours before using the IRCM and pretreatment protocol B was for 72 hours before. ⋯ Excellent results were found in 63.6% and good results were found in 36.4% for protocol A. Excellent results were found in 78.2% and good results were found in 21.8% for protocol B. However, no statistically differences were detected for both protocols (p = 0.451).

Abnormalities in exchange and tendency to acidosis and hypoxemia are present in acute asthma. Oxygen arterial saturation (pulse oximetry) is a simple and useful method to evaluate oxygenation conditions. Pulse oximetry and spirometry before and after albuterol nebulization (150 mcg/kg/dose) were performed in 35 subjects. 7 to 14 years, with acute asthma, 68% were mild and the rest moderate. ⋯ Spirometry before nebulization showed FEV1 20% predictive values in 18 children and increased in 10 of them. Seven were hospitalized because of worse symptoms. 4 of them showed metabolic acidosis by the presence of lactate. We conclude that pulse oximetry is a useful and simple method for an objective evaluation of acute asthma and its complications, but it is not predictive for a therapeutic decision.
