[Effect of 2 pesticides indoors on the respiratory function of a Mexican population].

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.

[Sensitivity and specificity of a questionnaire about respiratory symptoms similar to asthma].

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.

[Measurement of sIgA in patients with chronic stable bronchitis].

As we know secretory IgA of respiratory system has a very important role in defense mechanism. We studied 100 human beings, 50 healthy persons and 50 chronic bronchitis patients. Lavage nasal samples were tacked from healthy persons and sputum samples from chronic bronchitis patients. The laboratory test was nefelometry laser. Samples were analyzed was 1 student. Our results showed light increased of IgA in chronic bronchitis patients not significative. We concluded that this light increased is secondary to continuous stimulus of bronchial mucous as a part of defense mechanism.

[Comparative study of secretory IgA].

OBJECTIVE: The aim of this study was measure and compare Secretory IgA levels in the respiratory tract. DESIGN: Cross-sectional study. SETTING: Neumology Department of General Hospital. La Raza Medical Center Mexico. MATERIAL AND METHOD: There were 35 volunteers. Samples of sputum, washings nasopharyngeal and bronchial was obtained from thirty five patients with COPD. Measurement of SIgA levels was performed by nephelometric technique. Results is reported as ratio of SIgA concentration/Total proteins concentration named SIgA relative concentration. Correlation index was obtained of three type of samples. RESULTS: The SIgA values of sputum, washings nasopharyngeal and bronchial was similar similar +/- 0.011, 0.064 +/- 0.007 and 0.082 +/- 0.017 respectively). Multiple correlation was r = 0.508 (p < 0.01).
