Development and validation of a questionnaire to evaluate satisfaction of the patient with diabetes at the primary care level.

Aims: To develop and validate a new instrument to measure satisfaction with integral care (doctor-nurse) of the patient with type 2 diabetes mellitus, considering expectations-experiences together for the primary level of care.

Methods: The instrument was constructed with questions regarding integral care to measure the satisfaction of the diabetes patient and was classified into four domains. The validity of the content was done through a panel of experts, apparent validity through a focus group, the validity of the construct through analysis of the main components and confirmatory factorial analysis, instrument reliability with internal consistency, determined by Cronbach alpha and temporal stability (test-retest).

Human leukocyte antigen-associated susceptibility to pulmonary tuberculosis: molecular analysis of class II alleles by DNA amplification and oligonucleotide hybridization in Mexican patients.

Background: Pulmonary tuberculosis (PTB) develops by a complex combination of environmental factors with genetic susceptibility. In this context, an association between human leukocyte antigens (HLAs) and tuberculosis has been examined in several populations, but results have been controversial.

Design And Measurements: A prospective evaluation of class II HLA genotypes was completed by the polymerase chain reaction (PCR) sequence-specific primer technique and PCR sequence-specific oligonucleotide hybridization in a Mexican population.

[Intra-domiciliary low volume spraying of malathion and deltamethrin for controlling Anopheles sp].

The effectiveness of low volume (LV) house-spraying of deltamethrin 0.027 per cent and malathion 20 per cent in the control of Anopheles sp was evaluated in two villages of Tabasco, México during the last semester of 1987. Two spray rounds were carried out at three-month intervals, using Fontan R-12 back-pack-space sprayers.

Determinants and predictors of dengue infection in Mexico.

A national serosurvey was conducted in Mexico from March to October 1986 to identify predictors of dengue transmission and target areas at high risk of severe annual epidemics. A total of 3,408 households in 70 localities with populations less than 50,000 were randomly sampled, and serology was obtained from one subject under age 25 years in each household. When comparing exposure and infection frequencies across the 70 communities, the authors found that median temperature during the rainy season was the strongest predictor of dengue infection, with an adjusted fourfold risk in the comparison of 30 degrees C with 17 degrees C.
