A Metabolomic Signature of Ischemic Stroke Showing Acute Oxidative and Energetic Stress.

Metabolomics is a powerful data-driven tool for in-depth biological phenotyping that could help identify the specific metabolic profile of cryptogenic strokes, for which no precise cause has been identified. We performed a targeted quantitative metabolomics study in West African patients who had recently suffered an ischemic stroke, which was either cryptogenic ( = 40) or had a clearly identified cause ( = 39), compared to a healthy control group ( = 40). Four hundred fifty-six metabolites were accurately measured.

Surveillance of Viral Encephalitis in the Context of COVID-19: A One-Year Observational Study among Hospitalized Patients in Dakar, Senegal.

The burden of encephalitis and its associated viral etiology is poorly described in Africa. Moreover, neurological manifestations of COVID-19 are increasingly reported in many countries, but less so in Africa. Our prospective study aimed to characterize the main viral etiologies of patients hospitalized for encephalitis in two hospitals in Dakar.

Tolosa-Hunt Syndrome: A Painful Ophthalmoplegia.

Tolosa-Hunt syndrome is a painful ophthalmoplegia characterized by recurrent unilateral orbital pain, ipsilateral oculomotor paralysis, and a rapid response to steroids. Our report describes a 37-year-old young woman who presented with right ptosis, ipsilateral ophthalmoplegia, and painful headache with no other neurological deficits in which all biological and neuroimaging investigations were normal. Complete recovery within one week of corticosteroid therapy was observed.

Are Sub-Saharan epileptic people less photosensitive? A Senegalese study of photoparoxysmal response in a reference epilepsy centre.

The photoparoxysmal response (PPR) is defined as the occurrence of generalized spike, spike-wave or polyspike-wave discharges consistently elicited by intermittent photic stimulation (IPS). PPR is not well studied in Sub-Saharan African people. We prospectively studied the epidemiological, clinical, and EEG characteristics of PPR among consecutive patients recorded at the clinical neurophysiology unit of Fann University Hospital (Dakar, Senegal).

Conceptual framework for establishing the African Stroke Organization.

Africa is the world's most genetically diverse, second largest, and second most populous continent, with over one billion people distributed across 54 countries. With a 23% lifetime risk of stroke, Africa has some of the highest rates of stroke worldwide and many occur in the prime of life with huge economic losses and grave implications for the individual, family, and the society in terms of mental capital, productivity, and socioeconomic progress. Tackling the escalating burden of stroke in Africa requires prioritized, multipronged, and inter-sectoral strategies tailored to the unique African epidemiological, cultural, socioeconomic, and lifestyle landscape.

Neuromyelitis optica spectrum disorders (NMO-SD) in a Sub-Saharan Africa country: A preliminary study of sixteen Senegalese cases.

Background: Neuromyelitis optica (NMO) is an autoimmune disease of the central nervous system. In Sub-Saharan Africa, publications are rare and deal with isolated cases. Our goal was to analyze the characteristics of NMO spectrum disorders in a Senegalese cohort compiled in Dakar.

Metastatic Spinal Cord Compression Secondary to Liver Cancer.

Metastatic spinal cord compression (MSCC) is a medical emergency that requires rapid diagnosis and treatment to reduce pain, to preserve neurological functioning, and to prolong survival. The diagnosis of liver cancer is often neglected in the differential diagnosis of MSCC. Treatment is usually palliative and evolution is often fatal.

Post-ivermectin encephalopathy in Senegal: a case report.

Ivermectin is an ant parasitic drug used for combating onchocerciasis and lymphatic filariasis. It works by inhibiting the function of neurons and muscles, thus causing paralysis of microfilariae. Side effects of this drug have been reported including post-ivermectin encephalopathy requiring emergency care in hospital.

[Lipid and glucose profile in patients with ischemic cerebrovascular accidents in Dakar].

Cerebrovascular accident (CVA) is defined as the rapid development of localized or global clinical signs of neurological dysfunction with no apparent cause other than that of vascular origin. A variety of risk factors have been identified and associated with the occurrence of Ischemic CVA, including glucose and lipid metabolism disturbances. We conducted a retrospective study at the Clinic of Neurology, Fann.

Polymyositis anti-SRP antibodies and pregnancy about 2 cases.

Anti-SRP myopathy represents 4 to 6% of all the inflammatory myopathies. It has been described since the 80s and its influence on pregnancy and vice versa has been highlighted recently. We report two cases of anti-SRP myopathy associated with pregnancy.

[Epidemiological and socio-economic support patients living with epilepsy in Dakar, Senegal].

Background: Epilepsy remains a major public health problem especially in developing countries where access to new therapies remains limited.

Objective: The aim of this work was to study the socio-demographic profile of patients living with epilepsy in Dakar and supported.

Methods: We conducted a cross-sectional study over a period of eight months from November 2009 to June 2010 at Fann University Hospital and Health Center Pikine through research on adherence.

Addressing the treatment gap and societal impact of epilepsy in Rwanda--Results of a survey conducted in 2005 and subsequent actions.

This study, supported by the Rwandan Ministry of Health and the World Health Organization, was conducted in 2005 to determine the prevalence of epilepsy and its sociocultural perception in Rwanda, as well as epilepsy-related knowledge and practices of health-care professionals (HCPs). A cross-sectional, nationally representative survey was conducted throughout Rwanda by trained investigators. Participants were recruited by random cluster sampling based on the organization of administrative units in the country.

Cerebral neurocysticercosis mimicking or comorbid with episodic migraine?

Background: Neurocysticercosis is a major cause of neurological symptoms in developing countries. We report a case of cerebral neurocysticercosis presenting as episodic migraine without aura, with clinico-radiological correlations and discuss the possible causal influence of neurocysticercosis on the pathomechanisms of migraine.

Case Presentation: We report a 24 year-old male consulting for a one year history of recurrent headaches.

NeuroAIDS in Africa.

In July 2009, the Center for Mental Health Research on AIDS at the National Institute of Mental Health organized and supported the meeting "NeuroAIDS in Africa." This meeting was held in Cape Town, South Africa, and was affiliated with the 5th IAS Conference on HIV Pathogenesis, Treatment and Prevention. Presentations began with an overview of the epidemiology of HIV in sub-Saharan Africa, the molecular epidemiology of HIV, HIV-associated neurocognitive disorders (HANDs), and HAND treatment.

The global campaign against epilepsy in Africa.

One of the leading brain disorders in developing countries is represented by epilepsy. It is estimated that 80% of people suffering from epilepsy around the world, reside in developing world such as Africa. Many perinatal and postnatal causes are brain-stressers in people suffering from malnutrition and low economical conditions.
