[Asthma mortality trends in Mexico].

The objective of this cross-sectional study was to estimate mortality and morbidity from asthma in Mexico by federative entity (state) of residence, age, and sex during the period between 1960 and 1988. Statistics published by the National Institute of Statistics, Geography, and Information Science were reviewed, as were vital statistics and information from other sources. Data were selected on mortality, hospital admissions, and outpatient visits, as well as population by federative entity, age, and sex. Mortality and morbidity rates were adjusted for age using the direct method. From 1960 to 1987, mortality decreased for both sexes. The groups with the highest asthma mortality were those under 4 years of age and those over 50. From 1960 to the present, the state with the highest mortality was Tlaxcala. Hospitalizations increased from 10 to 140 per 100,000 population for the country as a whole. When both outpatient visits and hospitalizations were considered, the morbidity rates rose from 180 to 203.4 per 100,000 between 1960 and 1970. In 1970, hospital morbidity was higher among males than females. From 1960 up to the 1990s, the highest rates of hospitalization and outpatient visits were registered among those under 4 and those over 60. The states with the highest asthma hospitalization rates were Morelos, Baja California Sur, Nuevo León, Durango, and Tamaulipas. It is concluded that asthma mortality in Mexico is showing a downward trend, while morbidity is increasing considerably, especially among adolescents.

[Clinical and spirometric correlation with home allergens and with pollutants].

INTRODUCTION: Environmental contamination causes an increase in respiratory symptoms, especially in patients with asthma. The severity of allergic asthma in children is associated with the presence of intradomicilliary aeroallergens and intramural contaminants. OBJECTIVE: Correlation to clinical abnormalities, spyrometryand skin test with the intradomiciliary pollution. MATERIALS AND METHODS: Children who participated ranged in age from 6 to 15 years, attended public schools, and were classified as healthy and asthmatic. A questionnaire was applied to them, as well as a clinical history, spirometry, skin tests, and an environmental study at home. RESULTS: Fifty-seven children were studied, of 10 years of age (+/- 3). Group 1 (23 healthy children): Positive skin tests, dust 66.6%, cockroaches 66.6%, mites 33.3%, cat 33.3%, dog 4.3%. Principal clinical symptoms were cough 91.3%, wheezing 78.3%, respiratory difficulty 39.1% with a morning predominance of 78.3%. Spirometry showed an obstructive pattern in 30.5%. Group 2 (34 asthmatic children): Positive skin tests, mites 52.1%, dust 47.8%, cockroach 21.7%, cat 21.7%, dog 4.3%, passive exposure to tobacco smoke 79.5%. Principal clinical symptoms were cough 91.3%, respiratory 82.3%, wheezing 79.4%, predominantly at night 70.5%. Spirometry showed obstructive pattern in 67.7%. CONCLUSIONS: Children with asthma present great contact and sensitivity for intradomicilliary allergens such as mites in household dust, proteins from cat, dog, and cockroach feces, in addition to greater frequency of passive smoking. It is important to point out that these factors can be modifiable at low cost, thus presenting the conditions for a better quality of life for the patient and diminishing costs of medical attention.

[Results of an educational program for adults with asthma].

BACKGROUND: Asthma is a world health problem. Education of asthmatic patient has been proposed as a choice for diminishing mortality due to asthma. OBJECTIVE: To demonstrate that educational programs for asthmatic patients help to reduce disease's severity, crises and hospitalizations number and encourage a bigger therapeutic compliance. MATERIAL AND METHODS: 80 asthmatic patients were divided into two groups; first one received educational curse and second one does not. All patients received treatment according to international guides, including monthly consultation, flow-meter, and symptoms day book; an initial and final evaluation was made about disease's knowledge. Course consisted of a workshop including crisis management, use of inhaled medication, flow-metry and relaxation techniques. RESULTS: We studied 76 patients, with a mean age of 34 years; 36 were assigned to group 1 and 40 to group 2. Initial assessment of both groups was of 7.8, while final evaluation of groups 1 and 2 was of 9.3 and 8.4, respectively. Group 1 had lesser number of hospitalizations than group 2 (p-0.005), lesser number of emergency consultations (p-0.005) and a higher overall improvement than group 2, in which only 8 patients got well. A third part of the group 1 abandoned treatment, while patients that abandoned treatment in group 2 accounted for 79% (p < 0.0005). CONCLUSIONS: Educational programs for asthmatic adult patients diminish severity of disease, number of crises and hospitalizations, and also increase therapeutic compliance.

[The use of the International Guidelines for the Diagnosis and Treatment of Asthma (GINA) in clinical practice among family physicians].

OBJECTIVE: To evaluate the degree of knowledge of family physicians related to the International Guidelines for the Diagnosis and Treatment (GINA) of Asthmatic Patients. MATERIAL AND METHOD: We invited the family physicians from some clinics of Mexico City. A questionnaire was applied to 50 doctors who accepted to participate in the study; they had a 46 year-old age average and a proportion 1:1 between genders. The analysis was carried out with the test r of Pearson. RESULTS: The correlation between general knowledge of asthma and knowledge of GINA was r = 0.022; between the general knowledge of asthma and the specialty of family medicine was r = -0.117; and that among the knowledge on International Guides of Asthma and the specialty of family medicine was r = 0.33. CONCLUSIONS: A scarce knowledge exists on the guides proposed by GINA.

[Descriptive study of morbidity and mortality due to asthma at a Health Sector institution].

The objective of this study was to determine the morbidity and mortality rate due to asthma from a Health Institution, which represents the majority of working population. Asthma data were obtained from the National Institute of Informatical, Geography and Statistics (INEGI), Mexican Health Secretary (SS) and Mexican Social Security Institute (IMSS). The underlying cause of death hospitalization or visit were obtained. Asthma was coded according to the International Classification of Disease (ninth revision). Asthma death rate was adjusted by age using direct method. In the IMSS, asthma death rate increased from 3.24/200,000 in 1980 to 12.76/100,000 in 1990. The asthma letality increased from 0.34 in 1980 to 1.23 in 1990. The average length of hospital stay was 3.96 days in 1990; there was noy significant differences by sex the most affected groups were children under 4 years of age and persons older than 65 years of age. In conclusion, from 1980 to 1990, the morbidity and mortality rate due to asthma in IMSS increased. It suggests that future health policy efforts should be focused to reduce the morbidity, mainly in high risk groups.

[Electroretinography in non-insulin dependent diabetic patients].

The objective of this study was to determine the amplitude and temporal changes of flash electroretinogram, in nondependent insulin diabetic patients without diabetic retinopathy. Electroretinograms (Cadwell Quantum 84, Colliere) were obtained in thirty two healthy people and thirty two non-dependent insulin diabetic patients. We found decreasing time of a and b waves, in 26 diabetic patients, which suggests early retinal changes. There were no significant changes in amplitude and oscillatory potentials. The abnormalities on waves a and b were present 6.6 years after an set of diabetes; however, a relationship was not found between electroretinogram changes and duration of diabetes. In conclusion, there are decreasing times in the electroretinogram of non-dependent insulin diabetic patients before funduscopic changes are evident. Suggesting that electroretinogram may be useful to know and to follow-up early funduscopic changes in diabetic patients.

[Exposure to pollutants and allergens in the asthmatic child compared with the healthy child].

To assess the frequency of exposure to allergens and indoor pollutants of school age asthmatic children at the time of their first visit to the specialist, we studied 14 cases with the diagnosis of asthma according to international criteria, and 21 healthy controls. The parents of the children filed a questionnaire asking about socio-economic level, family history of asthma, exposure to allergens or indoor pollutants, and clinical severity of the disease. Questionnaires with less than 80% of the responses were excluded from analysis. Asthmatic patients had higher frequency of exposure to tobacco smoke (42.8% vs 38%), moisture in the home walls (42.9% vs 19%), and to dust reservoirs (71.4% vs 52.4%). A high proportion of the asthmatic patients did not apply adequate environmental control measures. Education for the patients and their primary care physicians must be increased, to reduce the morbidity of the diseases.
