Item Enzyme-linked immunosorbent assay of phenolic glycolipid-I in patients with Hansen's disease(Colombia Medica, 2010-09-07) Moreno, Luis Hernando; Alzate, AlbertoIntroduction: Hansen’s disease or leprosy is a contagious-infection entity produced by the Hansen bacillus or Mycobacterium leprae. The phenolic glycolipid is a special trisaccharide found in the bacillus cell wall and proved to be specific and immunogenic species during M. leprae. Objective: To determine the presence of the Hansen bacillus enzyme-linked immunoassay (ELISA) method glycolipid phenolic I in a group of patients in Dermatology Consultation at the Valle del Cauca Health Services; these patients were classified as cures or under watch according to criteria established by the World Health Organization (WHO). Methodology: From the data base of the Dermatology Consultation at the Valle del Cauca Health Services, we studied 159 patients with Hansen’s disease who were tested with the enzyme-linked immunoassay (ELISA) with the phenolic glycolipid I to cross reference information and observe if they were or were not positive to this test. A positive ELISA indicates the bacillus is still present in the patient. Results: As an important fact, we found that of 78 patients cured, when bearing in mind the monitoring period, 9 were positive for the ELISA. When this period was discarded, 81 sick individuals were classified as cured according to WHO criteria but the same 9 continued positive for ELISA. Conclusion: It may be concluded that in spite of meeting WHO criteria, these patients still show presence of the bacillus and the monitoring period is not required as a criterion to discharge a patient. We recommend adding to WHO criteria a negative ELISA, to obtain additional information that helps to certify that a patient is or is not cured.Item Vacunal cover in children 12 to 47 months old of social and economic 1 and 2 layers in the urban zone of Cali, year 2002(Colombia Medica, 2008) Rojas, Jorge H.; Zapata, Helmer; Alzate, Alberto; Rodríguez, ÁlvaroObjective: To estimate prevalence of complete vaccination sketch in children of ages of 12 to 47 months old in strata 1 and 2 into urbane zone of Cali in the year of 2002 according to biologics and the categories of socio-demographic variables of the family, the mother and child. Methods: The research corresponded to a cross section survey. The sample size used in the estimation process was 4452 children, drawn from conglomerates combined with strata by means of probabilistic sampling. The information was analyzed with Epi-Info version 6.04, with the Csample module for complex samples analysis. Results: The vaccination coverage with complete sketch for the first year was 65.8 (62.1-69.5), with significative differences for one and two strata (x2=42.4, p< 0.05). In the group of 12 to 47 months the belower coverages according to biologic were for anti-Haemphilus influenzae type B and anti-hepatitis B 71.8% (68.6-75) and 92.2% (90.1-94.3) respectively. Statistical association was found (test x2, p< 0.05) in comparing vaccination coverages with mother’s age, mother’s schooling, mother’s working time, family income and type of health system affiliation. Conclusions: The vaccination coverages in the studied population for some biologics were below, bearing in mind that the rule established by Colombian Ministry of Social Protection is to keep coverages into a minimum of 95%.
