[Wheezing in infants].
The wheeze are a common symptom in nursing, especially when suffer infections of the respiratory tract. They are common in 75 to 85% of the children, who have wheezes during some stage of their development between 2 to 5 years old. They can be related to smoking motherly during the pregnancy, exposition to the smoke of the tobacco to the subsequent stage to the birth, exposition to environmental and certain factor infections veers them. The wheezes in patient with atopy maybe they are related to a IgE two standard deviations up above of what is normal and persist as asthma in late stages. The wheeze is an affection syndromatic therefore it is obligatory to seek the factor unfetter you to arrive to a definitive diagnosis.

[Determination of immediate hypersensitivity to pollen in allergic patients in the Federal District].
AIMS: The immediate hypersensibility immediate mediated by IgE represents the damage mechanism type 1 according to the original classification of Gell & Coombs. MATERIAL AND METHOD: Observational study, descriptive, transverse in the one which were checked the files of 1250 patient of the Allergy Service of the Hospital Infantil de Mexico Federico Gomez with diagnostic of rhinitis allergic; asthma; asthma and rhinitis allergic. RESULTS: 1250 patient studied 468 were of the feminine sex (37.44%) and 782 (62.58%) of the masculine with a mean age in either case of 7.9 +/- 3.5 SD. With respect to result of cutaneous test 154 (12.32%) were negative and 1096 (87.68%) were positive to one or more antigens. CONCLUSIONS: The obtained results indicate the importance of accomplishing greater number of studies that relate not only the percentages of positive in the determination of immediate hypersensitive, but also to the frequency of pollens in the means to the one which is unfolded the patient, together with the stages of pollination throughout the Mexican Republic, in pediatric population as well as in adult, to effect cutaneous tests selects according to the zone and to stablish a specific treatment and adapted for each patient.
Asthma↗
[Procedure for bronchodynamic tests with inhaled allergens].
The asthma is one of the most frequent chronic illnesses in the children. It is characterized by hyperreactivity from the air roads to inspecific stimuli (metacholin and histamin) and specific (allergens). The broncodynamics tests determines the broncolability asthmatic boy's and they help to settle down the I diagnose functional. They should be carried out with antigenic extracts of high quality, lyophilized watery and standardized; you can use an open or closed circuit and a dosimeter, the initial dose of the allergen it is lower than with the one that the positive cutaneous reactivity was obtained, carrying out successive increments until the VEF-1 descend 15% or more. The patient's security is fundamental, they should be carried out for specialized personnel.

[Effect of heating on FEV-1 in children with asthma challenged with exercise].
AIMS: The exercise-induced bronchoespasm, also called asthma for exercise, it corresponds to a frequent clinical entity that commonly accompanies the asthmatic patient. Their frequency is of around the 80 to 90% for the patients with asthma; it is presented among 40 to 50% of the children with allergic rhinitis, in the athletes 14% and in the population's 12% in general. OBJECTIVE: To determine the effectiveness of a heating routine like preventive agent of the exercise-induced bronchoespasm. METHOD: 30 patients were included of between 10 and 16 years of age, asthmatic and with exercise-induced bronchoespasm by diagnosed by means of challenge test to the exercise. All the patients carried out an exercise routine with duration of 20 minutes during which movements of elasticity, calisthenics and light activity were made directed to the exercise to develop, taking as objective parameter 60% of the frequency heart submax. Did all the patients carry out challenge at once, again to the exercise, in which a band numberless was used, with speeds that were increased progressively from 1 to 8 km/h and with inclination of 0? 10 0. The spirometrics registrations was made before the challenge and at the 2, 5, 10, 15, 20, 25, 30 and 60 minutes after the same one. RESULTS: The average of the patient's age was of 12.8 +/- 2 years with size of 157 +/- 10 cm. CONCLUSION: The heating in children with broncoespasmo induced by exercise acts as a protective agent against the decrement of the VEF-1. Although the heating can be a good control method in the asthmatic patient, it is necessary to keep in mind that not all the patients have a benefit of this protection. This can only be used in patient with programmed physical activity, since in the preschoolers it is not possible to implant a heating routine for the characteristics characteristic of their activity.
