Clinical Profile and Outcome of Pediatric Demyelinating Disorders in Calabar, Nigeria: A Case Series.

BACKGROUND: Demyelinating disorders of the central nervous system (CNS) are rare disorders characterized by inflammation and the selective destruction of CNS myelin. The incidence of this disorder is increasing in developed countries. Nigerian studies on the pediatric population on the subject are very scarce. AIMS: The aim of the study was to document the epidemiology, clinical profile, and impact of late presentation on the treatment outcome of demyelinating diseases of the CNS in pediatric patients. METHODS: The retrospective review of patients aged 1-15 years admitted in a tertiary hospital from January 2018 to December 2022 with various symptoms suggestive of demyelinating CNS disorders. The diagnosis was clinically and radiologically confirmed. Information retrieved from the case notes included patients' demographics, clinical symptoms and signs, number of days with symptoms to presentation in the hospital, results of the magnetic resonance imaging (MRI), treatment, and treatment outcomes. Data were entered in Excel sheet and results were presented in tables and percentages. RESULTS: The incidence of demyelinating disorders over the period was 0.013% (10 out of 769 patients admitted over the period). Acute demyelinating encephalomyelitis (ADEM) was the most common disorder seen in the study population (60%, n = 6), followed by transverse myelitis and two (20%) had optic neuritis (ON). Most of the patients with ADEM were in the 1-5-year age group. The female-to-male ratio was 2.3:1. Paraplegia, visual impairment, and ataxia were the most common clinical presentations in the study population. One of the patients met the criteria for the diagnosis of multiple sclerosis during follow-up. Human immunodeficiency virus (HIV) was identified as the cause of demyelination in one case. Most of the patients improved with steroids. CONCLUSION: ADEM was the most common clinical phenotype seen in this study. Patients with ADEM and ON had a better prognosis than transverse myelitis. Late presentation was also identified as a poor prognostic factor. Follow-up of cases is very important to monitor disease progression to multiple sclerosis.

Seizure-related death in children with epilepsy

Children with epilepsy have a significantly higher rate of death than the general population. The cause of premature death among epileptics is contributed by the underlying cause, coexisting neurologic compromise and the epilepsy itself. Mortality directly related to seizures in paediatric epilepsy is the subject of this review. Seizure-related deaths in epileptics arise from status epilepticus, aspiration pneumonia, as well as sudden and unexpected death in epilepsy (SUDEP). Epilepsy per se enhances the risks of accidents and suicide. Children with epilepsy who are otherwise neurologically intact and with normal neuroimaging findings have an exceedingly low risk of seizure-related death. Poor compliance to antiepileptic drugs (AED) , poor ly co nt rol led (intractable and refractory) seizures, impaired cognition, structural/ metabolic aetiology and antiepileptic drug polypharmacy tend to carry poor prognosis. Therefore, parents need to be appropriately advised about the risk of seizurerelated premature death. Early identification, compliance with AED prescription, and treatment of comorbid conditions can reduce mortality risk and improve health outcomes in children with epilepsy. Children with intractable types of epilepsy may benefit from medical marijuana and neurosurgery

The burden of inpatient neurologic disease in a tropical African hospital.

BACKGROUND: Neurologic disorders represent a major burden of disease globally and the spectrum ranges from noncommunicable disorders like stroke and neurodegenerative disorders to central nervous system infections. OBJECTIVE: The purpose of the study is to assess the burden of neurological diseases in a tropical environment. METHODS: A one year retrospective survey of neurological diseases seen at the University of Calabar Teaching Hospital, Nigeria, was evaluated using patients' medical record. RESULTS: Neurological diseases constituted 24.2% of all medical conditions seen over a one year period. Stroke was found to be the commonest cause of admissions accounting for 42.1% of the cases followed by peripheral neuropathy (13.8%) and meningoencephalitis (7.2%). The immediate case fatality rate was 33.6%. Fifty two percent were discharged home with various levels of recovery while 12.5% left against medical advice. About 2% were referred to other tertiary health institutions. CONCLUSION: The pattern of neurologic diseases in the local medical wards was not remarkably different from those observed in Nigeria and elsewhere. Stroke remains the most frequent cause of neurologic admissions and mortality in this region is same as observed elsewhere.

Stray dog trade fuelled by dog meat consumption as a risk factor for rabies infection in Calabar, southern Nigeria.

BACKGROUND: Rabies is a preventable zoonosis with the highest case fatality of any disease in the world. In the developing world, it is transmitted mainly by dog bites. In parts of southern Nigeria, dog meat is a delicacy. OBJECTIVE: To highlight trade in stray dogs as a major risk factor for rabies in animals and humans in south-south Nigeria. METHOD: Patients admitted into the University of Calabar Teaching Hospital (UCTH) with a diagnosis of rabies between July and October 2012 were analysed for risk factors, post exposure prophylaxis (PEP), health seeking behaviour and outcome. Focused group interview were also conducted among traders/handlers of stray dogs. RESULTS: Ten cases of rabies in subjects aged 3 to 52 years were recorded in these five months period. Eight of the cases were male and apparently got infected directly or indirectly through the trade in stray dogs for human consumption. None had proper PEP and all patients died. CONCLUSION: Stray dog trade, fuelled by eating of dog meat, is a risk factor for human and animal rabies in Calabar, southern Nigeria. Culling of stray dogs, control of stray dogs' trade and public enlightenment on PEP is recommended.

The role of radiotherapy and chemotherapy in the treatment of primary adult high grade gliomas: assessment of patients for these treatment approaches and the common immediate side effects.

Gliomas are the commonest primary brain tumours in adults. They are usually classified and graded according to the criteria by the World Health Organisation. High-grade gliomas are the most malignant primary brain tumours. Conventional therapies include surgery, radiotherapy, and chemotherapy. The tumours often demonstrate high levels of resistance to these conventional therapies, and in spite of treatment advances the prognosis remains poor.
