Differences in clinical outcomes and resource utilization in pediatric traumatic brain injury between countries of different sociodemographic indices.

OBJECTIVE: The burden of traumatic brain injury (TBI) is disproportionately high in low- and middle-income countries (LMICs). This study aimed to compare clinical outcomes and healthcare utilization for children with moderate to severe TBIs between LMICs and non-LMICs in Asia and Latin America. METHODS: The authors performed an observational multicenter study from January 2014 to February 2023 among children with moderate to severe TBIs admitted to participating pediatric intensive care units (PICUs) in the Pediatric Acute and Critical Care Medicine Asian Network (PACCMAN) and Red Colaborativa Pediátrica de Latinoamérica (LARed Network). They classified sites according to their 2019 sociodemographic index (SDI). Low, low-middle, and middle SDI sites were considered LMICs, while high-middle and high SDI sites were considered non-LMICs. The authors documented patient demographics and TBI management. Accounting for death, they recorded 14-day PICU-free and 28-day hospital-free days, with fewer free days indicating poorer outcome. The authors compared children who died and those who had poor functional outcomes (defined as Pediatric Cerebral Performance Category [PCPC] level of moderate disability, severe disability, or vegetative state or coma) between LMICs and non-LMICs and performed a multivariable logistic regression analysis for predicting poor functional outcomes. RESULTS: In total, 771 children with TBIs were analyzed. Mortality was comparable between LMICs and non-LMICs (9.6% vs 12.9%, p = 0.146). Children with TBIs from LMICs were more likely to have a poor PCPC outcome (31.0% vs 21.3%, p = 0.004) and had fewer ICU-free days (median [IQR] 6 [0-10] days vs 8 [0-11] days, p = 0.004) and hospital-free days (median [IQR] 9 [0-18] days vs 13 [0-20] days, p = 0.007). Poor functional outcomes were associated with LMIC status (adjusted OR [aOR] 1.53, 95% CI 1.04-2.26), a lower Glasgow Coma Scale score (aOR 0.83, 95% CI 0.78-0.88), and the presence of multiple trauma (aOR 1.49, 95% CI 1.01-2.19). Children with TBIs in LMICs required greater resource utilization in the form of early intubation and mechanical ventilation (81.6% vs 73.2%, p = 0.006), use of hyperosmolar therapy (77.7% vs 63.6%, p < 0.001), and use of antiepileptic drugs (73.9% vs 53.1%, p < 0.001). CONCLUSIONS: Within Asia and Latin America, children with TBIs in LMICs were more likely to have poor functional outcomes and required greater resource utilization. Further research should focus on investigating causal factors and developing targeted interventions to mitigate these disparities.

Cerebral X-linked Adrenoleukodystrophy Presenting As Enlarging Cavum Vergae Cyst: A Case Report.

The cavum vergae cyst (CVC) is an uncommon brain malformation. Most patients with CVC are asymptomatic and do not require neurosurgical intervention. Separately, cerebral X-linked adrenoleukodystrophy (X-ALD) is one of the phenotypes of a genetic peroxisomal disorder that is seldom managed by neurosurgeons. We report an unusual case of cerebral X-ALD presenting as an enlarging CVC in a child, and discuss its nuances in corroboration with the literature. A previously well six-year-old male presented with confusion and fever. Urgent neuroimaging demonstrated a large CVC with resultant hydrocephalus. Of note, there were symmetrical areas of signal changes in the periventricular white matter bilaterally involving the corpus callosum, thalami, cerebral peduncles, midbrain, and pons in his MRI. Further investigations performed as part of his medical workup reported high plasma concentrations of very long-chain fatty acids (VLCFA). Put together, a diagnosis of cerebral X-ALD was confirmed. Initially, an external ventricular drain was inserted directly into the CVC under stereotaxy to decompress it. Subsequently, endoscopic fenestration of the CVC was performed as the definitive treatment. He recovered uneventfully from the neurosurgical interventions and proceeded for the treatment of his cerebral X-ALD. To our knowledge, this is the first report of cerebral X-ALD presenting as a CVC in a patient. This case adds to the limited literature for both rare conditions and highlights the importance of a multidisciplinary approach to management.
