Resumen: La calprotectina fecal es un biomarcador del estado inflamatorio intestinal, que podría ser útil en pediatría como una prueba no invasiva para la diferenciación de trastornos gastrointestinales orgánicos y funcionales. Objetivo. El objetivo de este estudio fue describir los niveles de calprotectina fecal en niños con trastornos gastrointestinales en Colombia.

Background Recently, hoarseness affecting the supraglottic structure has been reported in Kawasaki disease (KD). The objective of this study was to characterize the frequency of hoarseness in acute KD patients in Latin America.

Conclusions Hoarseness was found to be prevalent as a presenting sign of acute KD in younger children. Anemia may indicate the presence of active inflammation.

Introduction: Colombia and Latin America in general show low rates of Exclusive Breast Feeding (EBF), which are far from the goal of 50% EBF by 2025 proposed by the World Health Organization (WHO) (1). Home-Based Breastfeeding Support Programs (HBSP) are a strategy created to strengthen adoption and adherence to EBF during the first 6 months, with the ultimate goal of providing the benefits of this practice and of preventing complications related to its absence (2).

Abstract Children with cancer are at high risk for poor outcomes, and health care providers are often unfamiliar with best practices in infection care and prevention (IC&P) in this small and fragile population. Graduates of training courses in IC&P in immunocompromised hosts identified a need for a community that would enable members to share health care experiences, provide resources for continuing medical education, and foster collaborative research and quality improvement opportunities.

Introduction: Acute bacterial meningitis (ABM) is a public health problem. The disease has reemerged after the introduction of pneumococcal conjugate vaccines (PCVs) due to an increase in serotypes that are not covered. The objective was to determine the changes in the disease incidence before and after the introduction of the 10-valent vaccine (PCV10) in Colombia.

"Background: The SARS-CoV-2 outbreak in 2020 evolved into a global pandemic, and COVID-19 vaccines became rapidly available, including for pediatric patients. However, questions emerged that challenged vaccine acceptance and use. We aimed to answer these questions and give recommendations applicable for use in pediatric patients with cancer by healthcare professionals and the public.

"Abstract: Mucormycosis is a disease caused by opportunistic fungi of the order Mucorales that generally affects immunocompromised patients or those with underlying disease. It has a high mortality rate and is the third most common invasive fungal infection.

"Background: Pneumococcal conjugate vaccines (PCVs) have decreased pneumonia in children. Colombia introduced mass vaccination with PCV10 in 2012.

"Background Perry disease (or Perry syndrome) is an autosomal dominant neurodegenerative disorder characterized by parkinsonism, neuropsychiatric symptoms, central hypoventilation, weight loss and distinct TDP-43 pathology. It is caused by mutations of the DCTN1 gene encoding an essential component of axonal transport. The objectives were to provide the current state of knowledge on clinical, pathological and genetic aspects of Perry disease, as well as practical suggestions for the management of the disease.
