RESUMO
PURPOSE: Malignant chest wall tumors are rare in pediatrics. They require multimodal oncological treatment and local surgical control. Resections are extensive; therefore, thoracoplasty should be planned to protect intrathoracic organs, prevent herniation, future deformities, preserve ventilatory dynamics, and enable radiotherapy. METHODS: We present a case series of children with malignant chest wall tumors and our surgical experience with thoracoplasty using absorbable rib substitutes (BioBridge®), after local surgical control. BioBridge® is a copolymer made of a polylactide acid blend (70% L-lactic acid y 30% DL-lactide). RESULTS: In 2 years, we had three patients with malignant chest wall tumors. Resection margins were negative, without recurrence at follow-up. We achieved good cosmetic and functional results, and no postoperative complications. CONCLUSION: Alternative reconstruction techniques such as absorbable rib substitutes provide protection, guarantee a flexible chest wall, and do not interfere with adjuvant radiotherapy. Currently, there are no management protocols in thoracoplasty. This option represents an excellent alternative for patients with chest wall tumors. Knowledge of different approaches and reconstructive principles is essential to offer children the best onco-surgical option.

BACKGROUND: COVID-19 pandemic has led to changes in the presentation and treatment of surgical pathologies. Therefore, we aim to describe the influence of the COVID-19 pandemic on the clinical presentation and management of acute appendicitis (AAp) and its surgical outcomes. STUDY DESIGN: A multicenter cohort study with prospectively collected databases. Three high-volume centers were included and all patients over 18 years of age who underwent appendectomy for AAp were included. Multiple logistic regression and multinomial logistic regression were performed, and odds ratio, relative risk, and B-coefficient were reported when appropriate, statistical significance was reached with p-values < 0.05. RESULTS: 1.468 patients were included (709 in the pre-pandemic group and 759 in the COVID-19 group). Female patients constituted 51.84%. Mean age was 38.13 ± 16.96 years. Mean Alvarado's score was 7.01 ± 1.59 points. Open surgical approach was preferred in 90.12%. Conversion rate of 1.29%. Mortality rate was 0.75%. There was an increase of perforated and localized peritonitis (p 0.01) in the COVID-19 group. Presence of any postoperative complication (p 0.00), requirement of right colectomy and ileostomy (p 0.00), and mortality (p 0.04) were higher in the COVID-19 group. Patients in the pre-pandemic group have a lesser risk of mortality (OR 0.14, p 0.02, 95% CI 0.02-0.81) and a lesser relative risk of having complicated appendicitis (RR 0.68, p 0.00, 95% CI 0.54-0.86). CONCLUSION: Complicated appendicitis was an unexpected consequence of the COVID-19 pandemic, due to surgical consultation delay, increased rates of morbidity, associated procedures, and mortality, influencing the clinical course and surgical outcomes of patients with AAp.

Introducción: La sangre de cordón umbilical (SCU) ha sido reconocida como una fuente de células madre hematopoyéticas. Múltiples estudios han sido realizados con el propósito de determinar variables maternas y neonatales que afecten el volumen, el recuento total de células nucleadas y de células CD34+. El presente estudio correlaciona variables maternas y neonatales con el recuento total de células nucleadas y de CD34+ medidas en μL (microlitro). Materiales y Métodos: Estudio correlacional en el que se analizaron 50 muestras de sangre de cordón umbilical de gestantes atendidas en dos IPS, una de Bogotá y otra de Ubaté, (Cundinamarca), durante un período de 7 meses del año 2013. La selección de estas muestras fue basada en un muestreo no probabilístico. Se calculó el coeficiente de correlación de Pearson con su respectiva significancia estadística entre las variables cuantitativas de la madre y del neonato, y el volumen, el recuento de células CD34+ y el recuento total de células nucleadas por μL. Resultados: Se encontró correlación positiva entre la longitud del cordón y el recuento total de células nucleadas. Así mismo entre el volumen inicial de la muestra y el recuento total de células nucleadas y el recuento de células CD34+ en μL y en mL (mililitro). Discusión: Múltiples estudios se han desarrollado entorno a la búsqueda de variables maternas y neonatales que afectan la calidad de la muestra. En Colombia no se habían descrito las correlaciones encontradas en el presente estudio. Es por ello, que el desarrollo de nuevos estudios con diseños analíticos será enriquecedor.
Background: The cord blood has been recognized as a source of hematopoietic stem. Multiple studies have been conducted in order to determine maternal and neonatal variables that affect the volume, total nucleated cell count and CD34+ cells. This study correlated maternal and neonatal variables with the total nucleated cell count and CD34+ cells measured by μL. Materials and methods: Correlational study in which 50 samples of umbilical cord blood were analyzed of pregnant women at two health institutions, one at Bogotá and the other one at Ubaté, Cundinamarca, for a period of seven months of 2013. The selection of these samples was based on a non-probability sample. The Pearson correlation coefficient was calculated with their respective statistical significance between quantitative variables of mother and newborn, and the volume, the count of CD34+ cells and the total nucleated cell count measured by μL. Results: Positive correlation between the length of the umbilical cord and the total nucleated cell count was found. Similarly, correlation between total nucleated cell count with the initial volume and count of CD34+ cells in μL and mL was found. Discussion: Several studies have been conducted around to look maternal and neonatal variables that affect the sample quality, however, the Colombian literature has not described the correlation found in this study, so it requires the development of new research with designs of analytical studies to establish associations between the variables described.
Introdução: O sangue do cordão umbilical (SCU) tem sido reconhecido como uma fonte de células-tronco hematopoiéticas. Vários estudos têm sido realizados com a finalidade de determinar as variáveis maternas e neonatais que afetam o volume e a contagem total de células nucleadas e células CD34+. O presente estudo correlaciona as variáveis maternas e neonatais com a contagem total das células nucleadas e células CD34+ medidas em μL (microlitro). Materiais e métodos: Estudo correlacional no que 50 amostras de sangue do cordão umbilical de mulheres grávidas atendidas em dois IPs foram analisadas, uma em Bogota e outra em Ubaté (Cundinamarca), durante um período de 7 meses do ano 2013. A seleção destas amostras foi baseada em uma amostragem não probabilística. O coeficiente de correlação de Pearson foi calculado com a respectiva significância estatística entre variáveis quantitativas da mãe e do recém-nascido, assim como o volume, a contagem de células CD34 + e contagem total de células nucleadas por μL. Resultados: Correlação positiva foi encontrada entre o comprimento do cordão e a contagem total de células nucleadas. Também entre o volume da amostra inicial e contagem total de células nucleadas e contagem de células CD34+ em μL e em mL (mililitro). Discussão: Vários estudos têm sido desenvolvidos em torno da busca de variáveis maternas e neonatais que afetam a qualidade da amostra. Na Colômbia não tinham sido descritas as correlações encontradas no presente estudo. É por esta razão que será gratificante o desenvolvimento de novos estudos com desenhos analíticos.
