Hereditary hemorrhagic telangiectasia (HHT) is an autosomal dominant vascular dysplasia characterized by bleeding telangiectasias and arteriovenous malformations (AVMs) in the brain, lungs, liver, and gastrointestinal tract. In childhood, its manifestations are often subtle or absent, making it difficult to recognize. The lack of evidence in pediatrics, especially in Latin America, favors underdiagnosis and limits the timely management of its complications. This study describes the epidemiological, clinical, genetic, and therapeutic characteristics of pediatric patients with HHT at a referral center. Population and methods. Retrospective, descriptive study of pediatric patients evaluated between 2010 and 2022 in the HHT Unit of a referral center. Epidemiological, clinical, genetic, and therapeutic data were collected from the institutional registry. Results. A total of 158 patients were included, mainly from Buenos Aires and surrounding areas; nearly 70% consulted due to a family history of the disease. The average age at the first consultation was 9 years, with 52% of participants being female. HHT was confirmed in 80 patients using Curaçao criteria and/or genetic testing, with a positivity rate of 50%. Mutations were identified in ACVRL1 (56%), ENG (40%), and MADH4 (2.7%). Epistaxis was the most common symptom (92%), with an average onset at age 7. Pulmonary (13%), central nervous system (11%), hepatic (8%), and digestive (2%) AVMs were detected. Conclusion.

Population and methods. An observational, cross-sectional, prospective study in patients with sepsis hospitalized in PICUs in Argentina from September 15, 2021, to December 15, 2021. Results. A total of 3230 patients were admitted to 55 PICUs. We included 428 patients who had 476 events. The median age was 17 months (4.2-74.2). The prevalence was 14.7%, and the 28-day mortality rate was 16.5%; 36.7% of patients did not receive antibiotics within the first hour. Receiving more than 60 mL/kg of fluids in the first 60 minutes showed a negative trend in mortality.

The clinical characteristics and prevalence remained unchanged, whereas the administration of fluids and the use of vasoactive drugs changed, and mortality rates decreased significantly. Conclusions. Sepsis is an event of high prevalence and mortality in Argentina.

Skeletal dysplasias are rare genetic disorders that affect bone and cartilage development, with a prevalence of 3.2 cases per 10,000 newborns in South America.

This study aims to determine the prevalence of low birth weight, short body length, and body disproportion at birth in patients with a molecular diagnosis of achondroplasia (ACH), hypochondroplasia (HCH), SHOX gene alterations (SHOX), and familial hypophosphatemic rickets (FHR).
