Background: Intracranial subdural empyema (SDE) is a seemingly uncommon life-threatening ailment with varying presentations and outcomes. A variety of risk factors have been associated with predisposition to intracranial SDEs; however, they may be cryptogenic. There is an increased predilection for intracranial SDE in children and teenagers with paranasal sinusitis or middle ear infections.

Unlabelled: Vascular injuries lead to haemorrhagic shock and distal limb ischaemia, especially with an arterial injury. This life-threatening state mandates urgent evaluation and intervention to save life and limbs. The treatment aims to restore blood flow and replace lost blood within the golden hours, stabilising cardiovascular haemodynamics and averting irreversible ischaemic damage.

Background: Brain abscess in children is a neurosurgical emergency with potentially catastrophic outcome despite the advances made in neuroimaging techniques and antibiotic therapy. Symptoms are nonspecific and may vary with the child's age, location, size, numbers and stage of abscess, and the primary source of infection. Treatment is usually with broad-spectrum antibiotics in combination and surgical evacuation in most cases or antibiotics alone in selected cases with clear-cut indications.

Background: Myelomeningocele is associated with hydrocephalus in 35% to 90% of cases. Hydrocephalus is usually treated with insertion of ventriculoperitoneal shunt; however, there is growing evidence that endoscopic third ventriculostomy (ETV) with choroid plexus cauterization (CPC) is an alternative.

Objective: To compare the success rate and morbidity of ETV with CPC and ventriculoperitoneal shunt (VPS) as the primary treatment of hydrocephalus in patients with myelomeningocele.

Introduction: Informed consent is a basic ethical requirement in situations involving sharing of patients' data. It supports and upholds the ethical principle of respect for persons and individual autonomy. For Buruli ulcer (BU) patients, associated stigma renders them vulnerable, hence the need for emphasis on additional protection by ensuring obtaining informed consent before third party use of their data.

Subdural empyema (SDE), a common neurosurgical emergency in the developing countries, accounts for 15%-20% of localised paediatric intracranial infections. In regions where modern diagnostic tools are scarce and inaccessible, detection of SDE may be delayed with subsequent poor outcome. Percutaneous subdural aspiration in patients with open anterior fontanel may be the only surgical option in resource-poor regions of the world.

Complex craniofacial defects often create a reconstructive challenge in our region. We highlight two cases that demonstrate this problem and highlight the role of microvascular free flaps in covering these defects. The evolution of head and neck reconstruction as well as the peculiarities of these types of reconstruction in our environment are discussed.

Background: Diagnosis of antithrombin III (ATIII) deficiency as a common cause of thrombophilia is primarily based on the determination of antithrombin levels in plasma using a functional activity assay or an immunological assay, but local reference interval is lacking.

Aims: The aim of the present study was to determine pattern of antithrombin activity and local reference intervals for ATIII among Nigerians.

Subjects And Methods: A cross-sectional study was carried out among healthy blood donors at the Lagos University Teaching Hospital in Nigeria between the age range 18 and 65 years.

Object: Although shunts have been the mainstay in treating hydrocephalus over the past 5 decades, the use of endoscopic techniques in addressing this disorder in children offers both the neurosurgeon and the patient a unique opportunity to avoid shunting and its attendant complications. The combination of endoscopic third ventriculostomy (ETV) with choroid plexus cauterization (CPC) remains uncommon in most centers despite its potential promise. The authors sought to investigate the efficacy of combining ETV and CPC (ETV+CPC) in treating childhood hydrocephalus in Nigeria.

Background: This study explored the outcome of children with patent anterior fontanelles who were treated with trans-fontanelle ultrasound scan (TFUSS), which is more affordable and available than CT scan and MRI in the diagnosis of childhood intracranial pathologies and treatment of subdural empyema, in developing countries.

Patients And Methods: Seventeen infants with post-meningitic subdural empyema, diagnosed using trans-fontanelle ultrasound alone and treated with subdural tapping over a 31-months period, were studied.

Results: Eleven patients presented with grades II and III Bannister and William grading for level of consciousness in intracranial subdural empyema.

In the adult population, glioblastoma multiforme is one of the most common primary brain tumors encountered. Unfortunately, this highly malignant tumor represents over 50% of all types of primary central nervous system gliomas. The vast majority of GBMs develops quite rapidly without clinical, radiological, or morphologic evidence of a less malignant precursor lesion (primary or de novo GBMs), as compared to secondary GBMs that develop slowly by progression from diffuse low-grade astrocytomas.

Malignant gliomas such as glioblastoma multiforme (GBM) present some of the greatest challenges in the management of cancer patients worldwide, despite notable recent achievements in oncology. Even with aggressive surgical resections using state-of-the-art preoperative and intraoperative neuroimaging, along with recent advances in radiotherapy and chemotherapy, the prognosis for GBM patients remains dismal: median survival after diagnosis is about 14 months. Established good prognostic factors are limited, but include young age, high Karnofsky Performance Status (KPS), high mini-mental status examination score, O6-methylguanine methyltransferase promoter methylation, and resection of > 98% of the tumor.
