We report an analysis of the genomic diversity of isolates of Burkholderia pseudomallei, the cause of melioidosis, recovered in Colombia from routine surveillance during 2016-2017. B. pseudomallei appears genetically diverse, suggesting it is well established and has spread across the region.

A proliferating pilar tumor is a rare skin neoplasm that arises from the outer root sheath of a hair follicle. Presentation varies widely, as the tumor can be benign or malignant and has a high probability of recurring after excision. We report our experience managing 3 proliferating pilar tumors with different clinical presentations and pathology findings at Hospital de San José, Bogota, Colombia., (Copyright © 2019 AEDV.

Introduction: The complementary feeding (CF) comprises a period in the life of the infant that starts with the introduction of foods other than breast-milk. It is determined by social and environmental factors which facilitate or limit the appropriate initiation of this practice, directly affecting the nutri tional and health status of children., Objective: To identify barriers and facilities for the follow-up of nutritional recommendations regarding the early start of CF in children between 0 and 24 months of age belonging to a comprehensive early childhood care program., Materials and Methods: Phenome nological, longitudinal, qualitative study in which 43 in-depth interviews and 11 focus-groups were carried out. Predefined categories were the context of the mother, representations and experiences of gestation, meanings and experiences of breastfeeding (BF), and CF. The analysis included the rela tionships between the units of meaning and predefined and emerging categories., Results: The CF is a social practice which is the result of medical and popular knowledge mixture, however, the degree of influence that the latter has on mothers is higher due to the degree of support that they have from their close circle, especially from mothers, grandmothers, and women of the family. The lack of con ceptual and practical knowledge about exclusive breastfeeding (EBF) and CF prevents mothers from carrying out good practices. Most of them do not know clearly what is involved in the EBF, resulting in an early start of CF, or do not have objective criteria to assess their milk production. Despite having received specific training, CF started early in most cases, a fact in which close family influence was decisive., Conclusions: The CF experience is strongly influenced by sociocultural aspects not only of the mother but of her immediate circle, and the recommendations they received from health pro fessionals are not enough to change their practices. Therefore, it is necessary to improve CF support interventions.

Introduction: Vulnerability can be defined as a lack of material and immaterial resources, which prevents the use of opportunities that may advance one’s self-interest. The presence of these welfare resources prevents reductions in the quality of life. Objective: The objective of this study was to build an index of vulnerability using characteristics of the physical, human, social and functional capital of adults in three cities of Colombia in the year 2016 and to determine the factors that contribute most to vulnerability. Materials and methods: We conducted a transversal study with primary information sources applying 1,514 surveys among people aged 60 years and over in Medellín, Barranquilla, and Pasto. For the construction of the vulnerability index, we used factor analysis with varimax rotation and the principal component method. Results: The conditions that lead to a person’s vulnerability were related mainly to human capital (quality of life, mental health and habits). The other types of capital that contributed to vulnerability were physical capital (occupation), social capital (accompaniment), and functional capital (functional independence). The highest vulnerability was registered among the residents of Pasto. The factors associated with vulnerability were the city of residence, the sex, the educational level and the role of the person in the home. Conclusion: In 58.55% of elderly people vulnerability was explained by the use of time, the functional independence and the subjective well-being. These findings contribute to the improvement of the quality of life, mainly those related to maintaining functional independence as long as possible, being occupied, improving mental health, and avoiding the risks of depression, anxiety, cognitive deterioration and deleterious habits.

Objective: To determine genetic relatedness of clone Colombia(5) ST289 with invasive Streptococcus pneumoniae serotype 5 isolates recovered in nine Latin American countries., Methods: Forty-four invasive S. pneumoniae serotype 5 isolates recovered from children under 5 years of age in Bolivia, Chile, Dominican Republic, Ecuador, Nicaragua, Panama, Paraguay, Peru, and Venezuela were studied. Pulsed-field gel electrophoresis patterns of DNA treated with SmaI restriction enzyme were classified using Tenover's criteria and analyzed with the Fingerprinting II program to determine their genetic relatedness with the Colombian clone., Results: All isolates had a genetic similarity of 78.5% or more with the Colombian clone. Thirteen electrophoretic subtypes derived of pattern A were identified, and five of them (A5, A6, A8, A13, A27) comprised 61.4% of the isolates., Conclusions: Clone Colombia(5) ST289 is disseminated in Latin America. This is important because S. pneumoniae serotype 5 frequently causes invasive disease in the region and is associated with trimethoprim-sulfamethoxazole resistance.
