RESUMEN
BACKGROUND: Traumatic brain injury (TBI) and stroke have devastating consequences and are major global public health issues. For patients that require a cerebral decompression after suffering a TBI or stroke, a decompressive craniectomy (DC) is the most commonly performed operation. However, retrospective non-randomized studies suggest that a decompressive craniotomy (DCO; also known as hinge or floating craniotomy), where a bone flap is replaced but not rigidly fixed, has comparable outcomes to DC. The primary aim of this project was to understand the current extent of usage of DC and DCO for TBI and stroke worldwide. METHOD: A questionnaire was designed and disseminated globally via emailing lists and social media to practicing neurosurgeons between June and November 2019. RESULTS: We received 208 responses from 60 countries [40 low- and middle-income countries (LMICs)]. DC is used more frequently than DCO, however, about one-quarter of respondents are using a DCO in more than 25% of their patients. The three top indications for a DCO were an acute subdural hematoma (ASDH) and a GCS of 9-12, ASDH with contusions and a GCS of 3-8, and ASDH with contusions and a GCS of 9-12. There were 8 DCO techniques used with the majority (60/125) loosely tying sutures to the bone flap. The majority (82%) stated that they were interested in collaborating on a randomized trial of DCO vs. DC. CONCLUSION: Our results show that DCO is a procedure carried out for TBI and stroke, especially in LMICs, and most commonly for an ASDH. The majority of the respondents were interested in collaborating on a is a future randomized trial.

OBJECTIVES: To assess the frequency, interventions, and outcomes of children presenting with traumatic brain injury or infectious encephalopathy in low-resource settings. DESIGN: Prospective study. SETTING: Four hospitals in Sub-Saharan Africa. PATIENTS: Children age 1 day to 17 years old evaluated at the hospital with traumatic brain injury or infectious encephalopathy. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: We evaluated the frequency and outcomes of children presenting consecutively over 4 weeks to any hospital department with traumatic brain injury or infectious encephalopathy. Pediatric Cerebral Performance Category score was assessed pre morbidity and at hospital discharge. Overall, 130 children were studied (58 [45%] had traumatic brain injury) from hospitals in Ethiopia (n = 51), Kenya (n = 50), Rwanda (n = 20), and Ghana (n = 7). Forty-six percent had no prehospital care, and 64% required interhospital transport over 18 km (1-521 km). On comparing traumatic brain injury with infectious encephalopathy, there was no difference in presentation with altered mental state (80% vs 82%), but a greater proportion of traumatic brain injury cases had loss of consciousness (80% vs 53%; p = 0.004). Traumatic brain injury patients were older (median [range], 120 mo [6-204 mo] vs 13 mo [0.3-204 mo]), p value of less than 0.001, and more likely male (73% vs 51%), p value of less than 0.01. In 78% of infectious encephalopathy cases, cause was unknown. More infectious encephalopathy cases had a seizure (69% vs 12%; p < 0.001). In regard to outcome, infectious encephalopathy versus traumatic brain injury: hospital lengths of stay were longer for infectious encephalopathy (8 d [2-30 d] vs 4 d [1-36 d]; p = 0.003), discharge rate to home, or for inpatient rehabilitation, or death differed between infectious encephalopathy (85%, 1%, and 13%) and traumatic brain injury (79%, 12%, and 1%), respectively, p value equals to 0.044. There was no difference in the proportion of children surviving with normal or mild disability (73% traumatic brain injury vs 79% infectious encephalopathy; p = 0.526). CONCLUSIONS: The epidemiology and outcomes of pediatric traumatic brain injury and infectious encephalopathy varied by center and disease. To improve outcomes of these conditions in low-resource setting, focus should be on neurocritical care protocols for pre-hospital, hospital, and rehabilitative care.

Background: Glomus jugulare tumors (GJTs) are rare intra-cranial tumors. Commonly, these lesions present with cranial nerve palsies, headaches, and hydrocephalus. Rarely, GJTs present with spontaneous subarachnoid hemorrhage. However, there has never been a report of diffuse subarachnoid hemorrhage following ventriculoperitoneal shunt insertion in a patient who developed hydrocephalus secondary to any brain tumor in general or glomus jugulare tumors in particular. Observation: The authors presented an extremely rare complication of diffuse subarachnoid hemorrhage following the insertion of a ventriculoperitoneal shunt (VPS) in a 61-year-old female patient who was diagnosed to have both clinical and radiologic features of acute obstructive hydrocephalus secondary to a highly vascular huge glomus jugulare tumor. Conclusion: Subarachnoid hemorrhage following ventriculoperitoneal shunt insertion for hydrocephalus caused by a mass lesion is an extremely rare complication. Preoperative CT angiography should be strongly considered to look for the associated vascular malformations in extremely vascularized mass lesions. Given the not ubiquitous availability of all therapeutic options for GJTs, especially in low and middle income settings contributes for the poor outcome of GJTs and it fosters a global neurosurgery agenda.
RESUMEN
BACKGROUND: To date, only a few cases of sellar and suprasellar glioblastomas have been reported even though high-grade glioma constitutes the most common adult brain tumor, commonly arising in the cerebral hemispheres. It arises de novo from astrocytes within the optic nerve, optic chiasm, or optic tracts and is quite challenging to diagnose and treat. To the authors' knowledge, there are 72 cases (including this one) of optic glioma malignancies in the medical literature, 30 corresponding to glioblastomas. OBSERVATIONS: The authors present the diagnostic considerations and challenges, management strategies, and clinical course of a very large sellar-suprasellar glioblastoma in a 19-year-female who had never received radiation therapy or prior surgery. LESSONS: Sellar-suprasellar glioblastomas, although extremely rare, are known to occur and pose challenges in their diagnosis and preoperative treatment planning. The presence of diffusion restriction on diffusion-weighted magnetic resonance imaging in a mass lesion that has ring and nodular postcontrast enhancement in addition to absent calcification on computed tomography should be alert to the possibility of a high-grade mass. This is extremely important for preoperative patient counseling and planning for the multimodal treatments, because sellar-suprasellar glioblastomas carry a poorer prognosis than the common benign mass lesions in the region.
RESUMEN
INTRODUCTION: Increased intracranial pressure is usually measured with invasive methods that are not practical in resource-limited countries. However, bedside ultrasound, a non-invasive method, measures the optic nerve sheath diameter and could be a safe and accurate alternative to measure intracranial pressure, even in children. CASE REPORT: We report a case of a 15-year old patient who presented with severe headache, projectile vomiting, and neck pain for two months. The bedside ultrasound showed a 10 mm optic nerve sheath diameter and a Computed Tomography scan of her brain revealed obstructive hydrocephalus secondary to a mass in the fourth ventricle. After intervening, we were able to monitor the decrease in her optic nerve sheath diameter with ultrasound. CONCLUSION: Performing invasive procedures continues to be a challenge in the resource limited setting. However, bedside ultrasound can be a useful tool in emergency centres for early detection and monitoring of intracranial pressure.
INTRODUCTION: L'hypertension intracrânienne (HTIC) est généralement mesurée au moyen de méthodes invasives qui ne s'avèrent pas pratiques dans des pays caractérisés par des ressources limitées. Cependant, l'échographie au chevet des patients, une méthode non invasive, mesure le diamètre de la gaine du nerf optique (DGNO) et pourrait constituer une alternative sûre et précise pour mesurer l'HTIC, même chez les enfants. ÉTUDE DE CAS: Nous avons étudié le cas d'une patiente de 15 ans qui s'était présentée souffrant de violents maux de tête, de vomissements en jets et de douleurs au cou depuis deux mois. L'échographie au chevet de la patiente a révélé un DGNO de 10 mm et la tomodensitométrie du cerveau a révélé une hydrocéphalie obstructive associée à une masse dans le quatrième ventricule. Après intervention, nous avons pu surveiller la réduction de son DGNO à l'aide de l'échographie. DISCUSSION/CONCLUSION: La réalisation de procédures invasives reste un défi dans les contextes caractérisés par des ressources limitées. Cependant, l'échographie au chevet du patient peut être un outil utile dans les services d'urgence pour permettre la détection précoce et le suivi de l'HTIC.
