Abstract:
Objective: To know recommendations on breastfeeding by Mexican pedia-tricians. Methods: Cross-sectional, descriptive study conducted through a survey of Mexican pediatricians. Results: Two hundred and fifty-four pedi-atricians (range 27 to 72 years) were surveyed. Most of them worked in public hospital or private practice or both. Among them 94.5% recom-mended newborn early contact with mother and 54.3% rooming. Exclusive breastfeeding was suggested by 89.8%, out of them 51.9% for 6 months. Breastfeeding on demand was counseled by 88.2% and 84.6% without fixed schedules. Pacifier use was rejected by 86.6%. 51.2% used iron supplements and 59.5% used other vitamins. Stopping breastfeeding in special situations was suggested by 87.4%; of them, 86.6% in case of infection with AIDS; 74.4% if the mother used drugs; 74.4% by infection with hepatitis B virus; 49.6% in case of mastitis; 17.3% in newborns with jaundice; and 18.5% in other situations. Finally, 93.3% of pediatricians surveyed reported interest in breastfeeding; 54.7% obtained information in medical journals; 54.7% through medical courses, and 31.9% in books. 58.3% of respondents oriented on breastfeeding according to WHO recommendations; 31.5% did so regularly and 10.2% did not. Conclusions: Pediatricians play a major role in breastfeeding promotion, but their formation is scarce and they are not prepared to counsel patients. Governments of developing countries should promote breastfeeding to ensure the health and proper development of infants.

Abstract: Se utilizó una combinación de índices univariados, análisis gráficos y técnicas multivariadas para analizar cualitativa y cuantitativamente la composición taxonómica, estructura comunitaria y patrón de distribución espacial del ictioplancton en la región costera del Pacífico colombiano (zona de influencia de la Corriente de Colombia), considerando simultáneamente el grado de relación con los factores ambientales de temperatura, salinidad y clorofila-a durante la fase terminal del período cálido ENOS 2006-2007. En total se colectaron 543 larvas de peces, pertenecientes a 87 especies de 37 familias, destacándose por su abundancia la familia Myctophidae (26%) y Bregmacerotidae (17%). La variabilidad espacial de la abundancia y de las variables abióticas analizadas sugieren una alta homogeneidad biótica (ictioplancton) y abiótica en la zona de estudio. Sin embargo, al comparar los resultados obtenidos durante esta investigación con trabajos previos, se estableció que El Ni o 2006-2007 afectó drásticamente la estructura y abundancia del ictioplancton en la zona costera del Pacífico colombiano, confirmando además que la Corriente Colombia es el principal agente modulador de la distribución espacial de ictioplancton en esta región. In this research a combination of univariate index, descriptive analysis and multivariate techniques were carried out in order to describe the icthyoplankton taxonomic composition, community structure, spatial pattern of distribution in the coastal region of Colombia Pacific (Influence zone of the Colombian Current), considering simultaneously the grade with the environmental factors temperature, salinity and chlorophyll-a during the terminal phase of ENSO 2006-2007. 543 fish larvae were collected, belonging to 87 species of 37 families. The most abundant families were Myctophidae (26%) and Bregmacerotidae (17%). The spatial distribution of icthyoplankton and abiotic parameter demonstrate a high biotic and abiotic homogeneity in the study zone.

Abstract: Objetivo. Determinar la incidencia de bacteriemia relacionada con catéter y neumonía asociada a ventilador en ni os hospitalizados. Material y métodos. Estudio prospectivo. En el servicio de Pediatría del Hospital General Regional (HGR) No 1 del Instituto Mexicano del Seguro Social (IMSS), de Durango, México, durante 18 meses, de enero de 1999 a junio del 2000, se implementó un sistema de vigilancia epidemiológica activa para identificar episodios de neumonía y bacteriemia nosocomial de acuerdo a las definiciones operacionales de la Norma Oficial Mexicana (NOM). A los pacientes hospitalizados que por su patología requirieron de ventilación mecánica o de catéter intravenoso central se les hizo seguimiento desde el primer día de exposición hasta la detección del episodio de infección o su retiro. Se efectuaron hemocultivos y cultivos de aspirado traqueal. Se calcularon tasas de incidencia para la neumonía asociada a ventilador y de bacteriemia/sepsis por 1 000 días de exposición con sus respectivos intervalos de confianza al 95%. También se presenta la tasa mensual de la infección por días de exposición por medio de gráficas de control estadístico. Resultados. Se identificaron 47 episodios de bacteriemia/sepsis relacionada con catéter y 44 de neumonía asociada a ventilador. La tasa de incidencia de neumonía fue de 28 eventos por 1 000 días de exposición a ventilador y la de bacteriemia/sepsis fue de 26 eventos por 1 000 días de exposición a catéter intravenoso central. Los microrganismos gram positivos (61.11%) predominaron sobre los gram negativos (38.88%). Conclusiones. Este estudio documentó tasas de neumonía y bacteriemia en ni os, sustancialmente más elevadas que en otros informes, lo que hace necesario establecer lineamientos para la prevención de infecciones en ni os con catéteres intravasculares y sobre los cuidados que requieren los ni os sometidos a ventilación mecánica.

Abstract:

The diagnosis delay in new cases of HIV infection is a frequent fact. Our objective was to detect and analyse the lost opportunities and describe the characteristics of these patients. Method: The search was done by a revision of personal histories of new diagnosis of HIV infection from 1st January to 31st December 2011 in the database of VACH. We selected those that had consulted a doctor in the previous year in the Emergency area, Primary Care and Specialised Consultations in the database of the histories of the Public Health Service. We called low attendance if they came 1 - 3 times and high if over 3. We grouped patients into those that fulfilled criteria of diagnosis delay by count of CD4s. We called no diagnosis delay to those that had count of CD4 over 350, diagnosis delay under 350 and advanced disease under 200. Results: There were 107 new cases. The global percentage of DD was 61.7% of cases. From these, 45.38% fulfilled criteria of AD. It was possible to find information about the existence of previous sanitary attendance in 59 patients. From these 58% were diagnosed with delay, fulfilling criteria of AD in 27%. The predominant means of infection was sexual. 35 patients attended a healthcare level, 19 two and 5 three. 47.5% consulted over 3 times. They requested a total of 274 consultations. Discussion: The diagnosis delay is a reality. It took our attention that from 59 patients having requested previous medical assistance 58% were diagnosed with delay and 27% fulfilled criteria of AD. We found that almost half of them had been attended in 4 and up to 14 times, in some occasions with suggestive symptoms of HIV infection. Facing this discovery we think that some interventions should be undertaken to get an early diagnosis and the control of the outbreak.
