Standards for psychosocial care in pediatric cancer: adapted proposal for Latin American and Caribbean countries.

Objective: To highlight the objectives, achievements, challenges, and next steps for the World Health Organization's Global Initiative for Childhood Cancer (GICC) framework, a project designed to improve psychosocial care (PSC) in pediatric cancer centers across Latin America and the Caribbean (LAC).

Methods: The project was launched in Peru, the first GICC focal country, in November 2020. The diagnosis phase included a survey and a semistructured interview with health professionals to assess PSC practices in institutions, and a needs assessment survey for caregivers.

Posterior Mediastinal Mass: An Uncommon Presentation of a Branchial Cleft Cyst.

Branchial cleft anomalies are a heterogeneous group of congenital disorders that theoretically emerge due to incomplete obliteration of the branchial apparatus, components of the six main pairs of pharyngeal arches, during embryonic development. They can result in a cyst, a sinus, or a fistula. For a congenital lateral neck mass, they represent the most common diagnosis in pediatric neck pathology.

Molecular characterization of colorectal cancer patients.

Introduction: Colorectal cancer has a high incidence in the world population. Different molecular pathways, such as chromosomal instability, microsatellite instability, and epigenetics are involved in its development. Objective: To perform molecular characterization in 44 individuals with sporadic colorectal cancer.

[Newborn with syphilitic pemphigus in pandemic's time].

Congenital syphilis is the infection by Treponema pallidum of the newborn, due to mother-to-child transmission of spirochaetes during pregnancy. It remains as a major cause of preventable fetal and neonatal morbidity and mortality if the mother is not opportunely treated. This highlights the importance of an adequate prenatal control, early screening for maternal infection and timely treatment.

Estrogens and human papilloma virus oncogenes regulate human ether-à-go-go-1 potassium channel expression.

Ether-à-go-go-1 (Eag1) potassium channels are potential tools for detection and therapy of numerous cancers. Here, we show human Eag1 (hEag1) regulation by cancer-associated factors. We studied hEag1 gene expression and its regulation by estradiol, antiestrogens, and human papillomavirus (HPV) oncogenes (E6/E7).
