Pediatric hemispheric cerebellar low-grade gliomas: clinical approach, diagnosis, and management challenges-experience at a tertiary care children's hospital.

PURPOSE: This study aims to provide an exhaustive analysis of pediatric low-grade gliomas (pLGGs) in the cerebellar hemispheres, focusing on incidence, clinical characteristics, surgical outcomes, and prognosis. It seeks to enhance understanding and management of pLGGs in the pediatric population. METHODS: We conducted an observational, descriptive, retrospective, and cross-sectional study at a pediatric hospital, reviewing medical records of 30 patients with cerebellar hemispheric pLGGs treated from December 2014 to January 2023. Data collection included demographics, clinical presentation, imaging findings, surgical approach, postoperative complications, histopathological diagnosis, hydrocephalus management, and follow-up. Molecular markers and adjuvant therapies were also analyzed. RESULTS: The cohort predominantly presented with cerebellar symptoms, with 60% showing hydrocephalus at diagnosis. MRI with gadolinium was crucial for diagnosis. Surgical focus was on achieving gross total resection (GTR), accomplished in 70% of cases. Postsurgical hydrocephalus was less common, and cerebellar mutism was not reported. While a complete molecular analysis was not performed in all cases, available data suggest significant influence of molecular markers on prognosis and therapeutic options of pLGGs. CONCLUSIONS: This study highlights the unique clinical and molecular characteristics of cerebellar hemispheric pLGGs in children. The lower incidence of postoperative hydrocephalus and absence of cerebellar mutism are notable findings. Emphasizing a multidisciplinary approach, our findings contribute to a deeper understanding of pediatric pLGGs, underscoring the need for personalized treatment strategies and vigilant follow-up.

Abusive head trauma, protocols, and legal concerns in a South American Country.

The abusive head trauma (AHT) is a form of child abuse and is a frequent entity all over de world. It is particularly unique among medical diagnoses because of the legal implications imposed by the diagnosis. Therefore, it has been the subject of much legal controversy over the decades. Knowledge of the clinical signs and imaging findings of abusive head trauma is vitally important for early diagnosis. An oriented anamnesis, as well as a complete physical examination and obtaining adequate images of the central nervous system, play a significant role in confirming the presumptive diagnosis. The interdisciplinary approach (pediatricians, neurosurgeons, neuroradiologists, social workers, and other specialists) is the key in the management of these patients. The purpose of this article is to familiarize the pediatric neurosurgeon with some of the more common medicolegal issues surrounding AHT as well as to discuss legal commitments and ethical obligations of the neurosurgeon in Argentina (South America) based on 2 clinical cases.
