BackgroundFood allergy is a public health problem that has increased in the last decade. Despite the increasing rates in children, quality data on the burden of these diseases is lacking particularly in developing countries. Honduras has no studies in pediatric patients.ObjectivesThe objective of this research was to identify the most common sensitization patterns to food through epicutaneous skin testing and food allergy rates in children and their correlation with common allergic diseases in a group of patients from Hospital of Pediatrics Maria.MethodsCross-sectional retrospective, descriptive study in which records and database of all allergic patients in the immunology outpatient clinic from Hospital of Pediatrics Maria were reviewed between the periods of January 2015 through June 2016.ResultsA total of 365 children were analyzed, the age of participants were in the range from 1 to 18 years, with an average of 9.8 years. Sensitization to food allergens were found in 23, and 58.3% were poly-sensitized. The most common food allergens that patients were sensitized to: milk 9.0%, eggs 6.9%, peanut 4.9% and pork meat 4.4%. Food allergy was confirmed via oral food challenged in 9.3% of the patients. The most frequent food allergies found were: cow’s milk allergy 6%, hen’s egg allergy 5.2% and wheat allergy 1.9%.ConclusionsMilk and egg were the most common a food allergens found in the population studied. Most of the patients were found to be poly-sensitized. The frequent food allergies confirmed via oral food challenge were cow’s milk allergy, hen’s egg allergy and wheat allergy.

Marine sediments contamination by fission product 137 Cs-137m Ba is a fact since the period 1945-65, when plus than two thousand atomic explosion tests were performed mainly in the southern seas, earth region with minor population density. However, marine flows have produced dissemination of this radioactive pair through the sea bottom all over the world, at different levels, because the sea movement and natural decaying of radioactive pair: parent 137 Cs (t 1/2 = 30.17 years) and daughter 137m Ba (t 1/2 = 2.55 minutes). Radioactive detection of these contaminants, compared as percentage with that of natural 40 K (t 1/2 = 1.28 × 10 9 years, 0.0118% of elementary K) leads to radiation contamination factor (RCF), as one possible unit to measure the radioactive contamination intensity in different regions, as well to determine if there is some other possible source of this contaminant, for example water cooling from power nuclear reactors when it is discharged at sea. However, radioactive detection always implies an unavoidable statistical variation, which makes more difficult to appreciate the changes as function of time and region. But at beginning of this century, mass spectrometry has got impressive advances, which makes it much more precise and sensible than radioactive detection [1]. This paper attempts to measure with other units the radioactive contamination: 137 Cs atoms number per gram of sample, instead radioactivity, which could be more direct and with minor standard deviation that radioactive detection, solving at same time the isobars separation: 137 Cs versus 137m Ba plus elementary 137 Ba (11.23% of Ba element).

Objetivo: determinar las propiedades psicométricas de un instrumento de CV (CQoLC) y evaluar la calidad de vida (CV) de los cuidadores primarios (CPI) de pacientes con cáncer. Material y método: estudio tres fases: (1) evaluación de CV en CPI con un instrumento validado para población general y de pacientes que requieren atención médica (InCaViSa); (2) adaptación y piloteo del CQoLC y; (3) evaluación de confiabilidad, validez y normas del CQoLC. Se incluyeron 317 CPI de pacientes con diferentes diagnósticos oncológicos. Se realizaron análisis descriptivos de la CV reportada por los CPI. Para piloteo del instrumento se estimó el porcentaje de CPI que tuvieron dificultades para comprender algún reactivo. En la fase de validación se realizó un análisis factorial por ejes principales y la estructura propuesta se sometió a un análisis factorial confirmatorio (AFC). La confiabilidad se obtuvo a través del Alfa de Cronbach y el coeficiente Omega de McDonald’s. Finalmente, se estimaron los parámetros para calificación del CQoLC. Resultados: los CPI obtuvieron puntajes de “baja” a “muy baja” CV en la mayoría de las subescalas del InCaViSa. El CQoLC no mostró dificultades para su comprensión y se obtuvo una versión de nueve reactivos, distribuidos en cuatro indicadores, que explican el 45,62% de la varianza con adecuado ajuste en el AFC y adecuados índices de confiabilidad (Alfas de Cronbach de 0,496 a 0,866 y coeficiente Omega de McDonald’s = 0,868). Conclusiones: la CV de los CPI de pacientes con cáncer se encuentra afectada importantemente. El CQoLC es un instrumento especializado, que demostró ser adecuado como herramienta de cribado en las mediciones de auto-reporte.
