Enfrentamiento de la ingesta de cuerpo extraño en un Hospital Regional del sur de Chile / Management of foreign body ingestion at a Regional Hospital in southern Chile

Introducción: La ingesta de cuerpos extraños (ICE) es frecuente en pediatría y puede llevar a complicaciones. Nuestro objetivo es revisar la experiencia de nuestro centro en el manejo de estos pacientes y proponer un protocolo de tratamiento. Material y Método: Estudio transversal retrospectivo, observacional y descriptivo, en el cual se revisaron los informes endoscópicos y fichas de pacientes con diagnóstico de ICE manejados por la Unidad de Endoscopia Pediátrica del Hospital Clínico Regional de Concepción entre enero de 2013 y junio de 2017 (53 meses), totalizando 40 casos. El registro y análisis de los datos se realizó con Microsoft® Excel 2016® para MacOS®. Resultados: El promedio de edad fue de 3,96 ± 3,24 años. La moda estadística fue de 2 años. A todos los pacientes se les realizó una endoscopia digestiva alta. El CE más frecuente fue la moneda (61,9%). En 6 casos (14,2%) fue una pila de botón. La retención de CE fue en tercio proximal del esófago (30,9%), el cuerpo gástrico (26,2%) y el tercio distal del esófago (14,2%), extrayéndose principalmente con pinza de cuerpo extraño (90,4%). El 57,5% evidenció alguna lesión relacionada a la ubicación del CE, siendo la más grave la producida por pila de botón. Conclusión: La ICE en niños es una entidad potencialmente peligrosa, por lo que se hace necesario disponer de una unidad de endoscopia pediátrica y protocolos de manejo para evitar complicaciones, sobre todo con objetos de alto riesgo.

Introduction: Foreign body ingestion (FBI) is common in pediatrics and can lead to complications. The aim of the present study is to review the experience of our center in the management of these patients and to propose a treatment protocol. Material and Method: Retrospective, observational and descriptive cross-sectional study, in which the endoscopic reports and records of patients diagnosed with IFB managed by the Pediatric Endoscopy Unit of the Regional Clinical Hospital of Concepción between January 2013 and June 2017 (53 months) were reviewed, with a total of 40 cases. Data recording and analysis was performed with Microsoft® Excel 2016® for MacOS®. Results: The average age was 3,96 ± 3,24 years. The statistical fashion was 2 years. All patients underwent a upper gastrointestinal endoscopy. The most frequent FB was the coin (61,9%). In 6 opportunities (14,2%) was a button batery. FB retention was in the proximal third of the esophagus (30,9%), the gastric body (26,2%) and the distal third of the esophagus (14,2%), being extracted mainly with foreign body clamp (90,4%). The 57,5% showed some injury related to the location of the FB, being the most serious the produced by button batery. Conclusion: FBI in children is a potentially dangerous entity, so it becomes necessary to have a pediatric endoscopy unit and treatment protocols to avoid complications, especially with high-risk objects.

Relative cost-effectiveness of using an extensively hydrolyzed casein formula containing the probiotic Lactobacillus rhamnosus GG in managing infants with cow's milk allergy in Spain.

OBJECTIVE: To estimate the cost-effectiveness of using an extensively hydrolyzed casein formula containing the probiotic Lactobacillus rhamnosus GG (eHCF + LGG; Nutramigen LGG) as a first-line management for cow's milk allergy compared with eHCF alone, and amino acid formulae in Spain, from the perspective of the Spanish National Health Service (SNS). METHODS: Decision modeling was used to estimate the probability of immunoglobulin E (IgE)-mediated and non-IgE-mediated allergic infants developing tolerance to cow's milk by 18 months. The models also estimated the SNS cost (at 2012/2013 prices) of managing infants over 18 months after starting a formula as well as the relative cost-effectiveness of each of the formulae. RESULTS: The probability of developing tolerance to cow's milk by 18 months was higher among infants with either IgE-mediated or non-IgE-mediated allergy who were fed eHCF + LGG compared with those fed one of the other formulae. The total health care cost of initially feeding infants with eHCF + LGG was less than that of feeding infants with one of the other formulae. Hence, eHCF + LGG affords the greatest value for money to the SNS for managing both IgE-mediated and non-IgE-mediated cow's milk allergy. CONCLUSION: Using eHCF + LGG instead of eHCF alone or amino acid formulae for first-line management of newly-diagnosed infants with cow's milk allergy affords a cost-effective use of publicly funded resources because it improves outcome for less cost. A randomized controlled study showing faster tolerance development in children receiving a probiotic-containing formula is required before this conclusion can be confirmed.
