Comparative Study[Mother-infant rooming-in and beginning of breast feeding in a tertiary care hospital].
To establish a mother-baby's rooming-in program (RI) in a hospital that provides a tertiary level of care. ⋯ It is possible to establish RI and initiate breast feeding in a tertiary care hospital, even in mothers with cesarean section.

Comparative Study[Study of the validity and reproducibility of passive ozone monitors].
The aim of this study was to evaluate the validity and reproducibility between ozone measurements obtained with passive ozone monitors and those registered with a continuous ozone monitor, to determine the applicability of passive monitors in epidemiological research. The study was carried out during November and December 1992. Indoor and outdoor classroom air ozone concentrations were analyzed using 28 passive monitors and using a continuous monitor. ⋯ Also, the correlation between the measurements obtained with two different passive monitors exposed concurrently was very high (r = 0.97, p < 0.001), indicating a good reproducibility in the measurements of the passive monitors. The relative error between the concentrations measured by the passive monitors and those from the continuous monitor tended to decrease with increasing ozone concentrations. The results suggest that passive monitors should be used to determine cumulative exposure of ozone exceeding 100 ppb, corresponding to an exposure period greater than five days, if used to analyze indoor air.

Comparative Study[The coverage of health institutions in the state of Mexico. A comparative analysis of the insured and uninsured populations].
In this paper we report on a survey aimed at comparing utilization patterns and institutional coverage of health services between insured and non-insured populations. Our results show that under fixed socioeconomic characteristics, and for the same health problems, the non-insured group had a utilization rate 1.5 times smaller than that corresponding to the insured. ⋯ On the other hand, private services utilization was 1.7 times higher for the non-insured population. These results point to the need for alternative and more equitable health care models in Mexico.

Few diseases have unique clinical findings sufficient to identify them. Dengue fever is not one of them, being necessary the clinical and laboratory support to confirm its diagnosis. Since dengue virus was first isolated, there has been a worldwide effort to develop cheaper and more accurate serologic diagnostic tests. ⋯ In addition to the wide circulation of serotypes 1, 2 and 4 for over a decade in the Americas, the presence of Den-3 was detected again in 1994 since its last appearance in 1963 and 1977. Given the high rates of vectorial infestation and the presence of a susceptible population, the probability of circulation of this serotype in our continent is high. The present work defines the wide range of diagnostic methods available today, their advantages and disadvantages, and their importance in the epidemiological surveillance of dengue fever in Mexico.
