What We Do - Our Projects
Global Neurosurgery Research Lab
Our current research work includes measuring neurosurgical capacity, burden of neurosurgical conditions, and identifying gaps in neurosurgical care delivery.
Research Projects
International Neuro-Oncology Consortium Project
Central Nervous System (CNS) tumors are the number one cause of death in children. The burden of CNS tumors has been estimated to be nearly four times greater in low middle income countries (LMIC). However, the true burden of these tumors and scope of resources for management of these tumors is not well-reported. This multiphase research project is led by Dr Michael Dewan and Dr Josie Haizel-Cobbina.
- Phase I (completed): The team conducted a cross sectional epidemiological survey to collect and analyze data on hospital-level burden, treatment outcome, and follow-up paradigm of pediatric CNS tumor cases from 7 pediatric neurosurgical oncology centers in Sub-Saharan Africa
- Phase II (completed): A self-administered questionnaire was completed by neurosurgeons at the 7 centers providing data on national neurosurgical workforce and hospital diagnostic and treatment capacity for CNS tumors
- Phase III (ongoing): A qualitative study led by Dr Lakshmi Suryateja Gangavarapu to understand the landscape of obstacles to care for pediatric patients with CNS tumors at Komfo Anokye Teaching Hospital (KATH), Ghana. The investigation will be conducted through semi-structured interviews with caregivers of pediatric patients with a history of CNS tumors, healthcare providers at KATH, health institutional leaders, and religious leaders.

Disseminated Pediatric Low Grade Glioma Consortium
Disseminated pediatric low grade gliomas (dPLGGs) have been observed to exhibit distinct biologic behavior with some tumors appearing as upfront disseminated cystic solid tumors throughout the brain and spine, large single tumor with dissemination in the membrane surrounding the brain and spinal cord or start as a single tumor which later disseminates to other parts of the brain and spine. This study aims to characterize the genetic alterations found in dPLGGs in view of these three clinically important subgroups using next generation genomic technologies and correlate this with the clinical features and outcome of the disease. Identification of drivers of metastasis/dissemination will allow early identification of these aggressive tumors, facilitate risk stratification of newly diagnosed PLGGs and management of the disease.
This study funded by Pediatric Brain Tumor Foundation is led by Dr Michael Dewan in collaboration with The Hospital for Sick Children, Toronto, Canada.
Pediatric Hydrocephalus and Neural Tube Defect Management in Ghana
Epidemiological studies and clinical follow-up studies on pediatric hydrocephalus and neural tube defects are largely absent in most LMICs. These studies are important in estimating the disease burden and evaluating treatment outcomes, and follow-up for children with these conditions. Study findings will also help guide the implementation of interventions aimed at reducing the incidence of cases and improving outcomes.
This study led by Dr Josie Haizel-Cobbina will be the first determine the epidemiology and treatment outcome of pediatric hydrocephalus and neural tube defect in the middle belt of Ghana.
Establishing Neurotrauma Registry in LMICs
There is a disproportionate burden of traumatic brain and spine injuries (TBI & TSI) in low-and middle-income (LMICs) with higher morbidity and mortality compared to high income countries (HICs). To bridge the gap in the delivery of care to TBI and TSI patients in LMICs, it is important to be able to collect and analyze relevant epidemiologic data to better understand the burden of disease, mechanism of injuries, and develop neurosurgical infrastructure to properly assess and treat these patients. The data will also guide the implementation of policy interventions and programs aimed at neurotrauma prevention. Using Ghana as a model LMIC, this project seeks to establish a neurotrauma registry at a major neurosurgical referral center in Kumasi-Ghana to help determine the epidemiology and treatment outcomes of TBI and TSI patients. This project is led by Dr Josie Haizel-Cobbina in collaboration with Dr Nancy Abu-Bonsrah.
