Pediatric brain tumors are most common cancers in childhood and among the leading causes of death in children. Chemotherapy has been used as adjuvant (i.e. after) or neoadjuvant (i.e. before) therapy to surgery and radiotherapy for the management of pediatric brain tumors for more than four decades and gained more attention in the recent two decades. Although chemotherapy has demonstrated its effectiveness in the management of some pediatric brain tumors, failure or inactiveness of chemotherapy is commonly met in the clinics and clinical trials. Some of these failures might be attributed to the blood-brain barrier (BBB), limiting the penetration of systemically administered chemotherapeutics into pediatric brain tumors. Therefore, various strategies have been developed and used to address this issue. Herein, we review different methods reported in the literature to circumvent the BBB for enhancing the present of chemotherapeutics in the brain to treat pediatric brain tumors.

Clinical features, treatment modalities, and survival rates of pediatric central nervous system tumors: A retrospective analysis from a single center (2000-2020).

Pediatric central nervous system (CNS) tumors represent 20-25% of childhood malignancies, with 35-40 new cases annually in Slovakia. Despite treatment advances, high mortality and poor quality of life in a lot of cases persist. This study assesses the clinical features, treatment modalities, and survival rates of pediatric CNS tumor patients in the single largest center in Slovakia.

Differentiating benign enlargement of subarachnoid spaces (BESS) from low-attenuation subdural collections on CT imaging of infants can be challenging. This distinction is crucial in infants, as subdural collections may raise the concern for abusive head trauma (AHT). To evaluate the utilization of the displaced cortical vein sign on CT as a predictor of pathological subdural collections confirmed by MRI and to assess the reproducibility of this finding among radiologists with different levels of clinical experience.

The diagnosis of abusive head trauma (AbHT) in children is a challenging one that needs to be differentiated from natural disease and accidental head injury (AcHT). There is increasing evidence from the Neuroradiology field showing spinal cord injury in children subject to AbHT, which has, so far, been poorly investigated pathologically. In this study we retrospectively reviewed the forensic records of 110 paediatric head injury cases over an eight-year-period.

Purpose: To describe the clinical characteristics of glaucoma-related adverse events (GRAE) after pediatric cataract surgery. More importantly, to identify the factors associated with the time of GRAE onset and the preferred anti-glaucomatous surgical procedure for this disease.
Methods: Hospitalized medical records of patients who developed GRAE, which include glaucoma and glaucoma suspect, after pediatric cataract surgery (surgical age ≤ 14 years) between 1994 and 2021 were retrospectively reviewed.
Edaravone Mitigates Hippocampal Neuronal Death and Cognitive Dysfunction by Upregulating BDNF Expression in Neonatal Hypoxic-Ischemic Rats.

Neonatal hypoxic-ischemic encephalopathy (HIE) is a severe neurological injury during infancy, often resulting in long-term cognitive deficits. This study aimed to investigate the neuroprotective effects of Edaravone (EDA), a free radical scavenger, and elucidate the potential role of brain-derived neurotrophic factor (BDNF) in mediating these effects in neonatal HIE rats. Using the Rice-Vannucci model, HIE was induced in neonatal rats, followed by immediate administration of EDA after the hypoxic-ischemic insult.
