RESUMO
INTRODUCTION: Questionnaires are an epidemiological instrument to detect patients with asthma. MATERIALS AND METHODS: Worldwide standardized questionnaires were selected, taking the most important points for making the diagnosis of asthma. A questionnaire was applied to outpatients who attend to pulmonary disease service. The answers were compared with a "gold standard" proposed, consisted in clinical screening and pulmonary function tests. STATISTICAL ANALYSIS: Kappa coefficient, sensitivity, specificity and predictive values were obtained, with intervals of confidence of 95%. RESULTS: The questionnaires were applied to 120 patients, 70.83% women, the answering percentage was 99%. Mean age was 32 years with a range of 24-40. In 62.5% patients there was already a previous diagnosis of asthma. Positive Familial history was present in 65.83, cough in 85%, dyspnea in 80.83%, sneezes in 53.33% and wheezes in 77.5%. The was of kappa coefficient for previous medical diagnosis 0.96%, followed by positive familial history, wheezes and cough in 0.90%. The greatest specificity was for wheezes, dyspnea and previous medical diagnosis. The greatest specificity for previous medical diagnosis was wheezes and sneezes. CONCLUSIONS: The use of questionnaires for respiratory symptoms similar to asthma can be an option to detect groups of high risk.

INTRODUCTION: The utilisation of pesticides in the large cities has been increased. Exist few studies that determine the damage in the respiratory appliance. OBJECTIVE: Determined on a healthy population of Mexico City with two known products used for the control of the insecticides in household, with the main objective to determine the clinical and functional manifestations that its use implies. MATERIAL AND METHODS: They were included 70 sound volunteers with residence in the City of Mexico that lived in apartments with 100 square meters of construction, tobacco negative and without previous antecedents of cardiovascular disease, without acute infectious process. They were split into 2 groups one that inhaled pesticides for combustion and the group b in electric form, In them I accomplished study espirometric to the beginning and during 3 exposed hours. The analysis by T Student. RESULTS: In group A was observed a meaningful difference of 0.01 in the first hour and of p < 0.028 in the second and third hours, with collateral effects as irritation eyes (74%) disnea (57%) cough (43%) and headaches (28%). Group B with a small difference of the VEF-1 in the first hour p < 0.03 and without differences on the following hours. We haven't observed secondary effects according to this group. The analysis en both group we have only differences in the first hours with p < 0.004. CONCLUSION: The exposition to pesticides our group for combustion produces a lot of clinical and functional alterations than the electric pesticides.
