Proton-Based Radiation Therapy for Skull Base Chondrosarcomas in Children and Adolescents: 40-Year Experience From the Massachusetts General Hospital.

Purpose: The literature on skull base chondrosarcoma (CHS) is scarce. We report outcomes for pediatric and young patients ≤22 years with base of skull CHSs treated with proton-based radiation therapy (PBRT).

Methods And Materials: We retrospectively reviewed all patients treated with PBRT between 1981 and 2023.

Clinical approach for managing patients with unexpected CDH1 mutations: A case report.

Background: Hereditary diffuse gastric cancer (HDGC) (OMIM# 137215) is an autosomal dominant cancer syndrome associated with CDH1 (OMIM# 192090) mutations. Prophylactic total gastrectomy (PTG) is the most recommended preventive treatment when a pathogenic mutation is found. However, the increasing use of genetic testing has led to the identification of incidental CDH1 mutations in individuals without a family history of gastric cancer.

Prescribing practices of inhaled corticosteroids for premature infants in the neonatal intensive care unit.

Objective: Despite limited safety and efficacy data, inhaled corticosteroids (ICS) are prescribed to premature infants in the neonatal intensive care unit (NICU). We examined contemporary use and risk factors for ICS use in the NICU.

Study Design: Infants <33 weeks gestational age and <1500 gm birth weight discharged from Pediatrix Medical Group NICUs between 2010 and 2020 were included.

What is the actual relationship between neutrophil extracellular traps and COVID-19 severity? A longitudinal study.

Background: Neutrophil extracellular traps (NETs) have repeatedly been related to COVID-19 severity and mortality. However, there is no consensus on their quantification, and there are scarce data on their evolution during the disease. We studied circulating NET markers in patients with COVID-19 throughout their hospitalization.

The c.386A>C p.(Asn129Thr) variant in SMAD4 is likely to be pathogenic, causing Juvenile Polyposis Syndrome. A case report of a mosaic variant.

Background: Juvenile Polyposis Syndrome (JPS) is a rare autosomal dominant hereditary disorder characterized by the development of multiple hamartomatous gastrointestinal polyps. Here, we present a case of JPS with a mosaic variant in SMAD4.

Methods: Exome sequencing TRIO analysis, using germline DNA from the biological mother and father along with the index case (IC).
