Guillain-Barré syndrome in ulcerative colitis and SARS-CoV-2 infection: a case report and literature review.

Guillain-Barré syndrome (GBS) occurrence is rare during inflammatory bowel disease (IBD) and SARS-CoV-2 infection. Its association with thrombotic vascular events, which are common during these two entities, is extremely rare. We report an exceptional association of GBS and cerebral venous thrombosis in a 28-year-old woman with active ulcerative colitis and no previous history of SARS-CoV-2 vaccination.

Vitamin D receptor gene BsmI (rs1544410) polymorphism: role in multiple sclerosis and genotype-phenotype correlations.

Background: Multiple sclerosis (MS) has a complex pathophysiology which depends on many endogenous and exogenous factors. Vitamin D involvement has been largely studied in MS. The large distribution of the vitamin D receptor (VDR) in different immune cells is suggestive of an immunomodulatory role.

Cognitive impairment in multiple sclerosis: Utility of electroencephalography.

Objective: to evaluate associations between neurocognitive impairment and electroencephalography (EEG) data in Multiple Sclerosis (MS).

Methods: patients aged between 18 and 65 years, diagnosed with MS accordingly to the McDonald 2017 criteria and who were in remission for at least one month were included. Cognitive functions were evaluated by validated neuropsychological tests for Tunisian population.

COVID-19 Infection and Recurrent Stroke in Young Patients With Protein S Deficiency: A Case Report.

Introduction: Protein S deficiency and coronavirus disease 2019 (COVID-19) are rare etiologies of ischemic stroke. We describe a case of an ischemic stroke revealing severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in a patient with a history of protein S deficiency and cerebral imaging suggestive of vasculitis.

Case Report: A 52-year-old woman, with history of protein S deficiency, was admitted for right hemiparesis and aphasia that happened 6 hours before her consultation.

Knowledge and attitudes toward epilepsy among teachers in Tunisia.

Background: The importance of school teachers' knowledge of and attitudes toward epilepsy and its contribution in improving the links between the Education and Health fields, is well recognized and appreciated. In order to clarify the amount of misconceptions about epilepsy among Tunisian teachers, we conducted a web-based survey. The main objectives of our study were, first, to determine the knowledge about and attitudes toward epilepsy, and second, to specify factors associated with a better understanding of this disease.

Utility of EEG on attention deficit-hyperactivity disorder (ADHD).

Objective: The aim of our study was to analyze electrophysiological findings in patient with Attention Deficit Hyperactivity Disorder (ADHD) by electroencephalography (EEG) recording, estimate the prevalence of epilepsy in ADHD population and assess its clinical characteristics.

Methods: We conducted a retrospective and analytic study that concerned children with ADHD, followed for at least two-years in the Tunisian National Center for School and University Medicine (NCSUM). All patients recruited underwent at the diagnosis of ADHD, neurological examination and EEG recording in the department of Neurology of Charles Nicolle Hospital.

Epileptic seizures and occupational exposure to solvents: a cases series.

Introduction: Organic solvents (OS) are substances with well-known nervous system tropism. Long-term exposure can cause several neurological and neuropsychic manifestations (mainly toxic encephalopathy). A potential causal relation between epileptic seizures and exposure to OS remains controversial.

The Adaptation and Validation of an Arabic Version of the Cornell Scale for Depression in Dementia (A-CSDD).

Background: Depression is a major disorder that can be ttriggering, exacerbating, or co-occurring with dementia symptoms. Its assessment is paramount to achieve diagnostic, prognostic, and therapeutic decisions. The Cornell Scale for Depression in Dementia (CSDD) is purposely designed to address clinically this issue.

[Pott's disease of the upper cervical spine (three cases and literature review)].

Background: Sub-occipital Pott's disease is rare, but dangerous.

Aim: To recall diagnostic aspects and spatially the neuroradiological ones of sub-occipital Pott's disease.

Methods: We describe three patients with sub-occipital Pott's disease followed in our department from 2002 to 2007.

[Xeroderma pigmentosum. Cutaneous, ocular, and neurologic abnormalities in 49 Tunisian cases].

This is a retrospective study about 49 cases of xeroderma pigmentosum (XP). The goal was to determine the clinical features of XP in Tunisia. Our study revealed the predominance of a moderate form.

[Mesial temporal lobe epilepsy. Nine case reports].

Introduction: Mesiotemporal epilepsy (MTLE) is a clinical syndrome characterised by the association of a history of febrile seizures, a homogenous clinical presentation of seizures, temporal interictal and ictal EEG recordings and an underlying pathology that is mesial sclerosis. MTLE is the most common type of medically intractable partial epilepsy with a drug-resistance in 90% of cases.

Object: The aim of this study is to describe the clinical, EEG and MRI findings of 9 patients with MTLE attending the outpatient clinic of Charles Nicolle Hospital.

[School failure and epilepsy: a case-control study].

School difficulties and educational inadequacy usually correlate with the child's epilepsy. The target of our study is to discover the most precocious possible the epilepsy and to prevent educational failure in the population of children from 6 to 15 years old. We have carried out a retrospective study on 162 children of an educational age.

[Cerebral venous thrombosis and Behcet's disease].

Behcet's disease is a chronic relapsing multisystem disorder of unknown etiology. Neurological complications are frequent, occurring in 10 to 49% of cases. We report 4 cases with Behcet's disease (3 females and 1 male) who had symptomatic intracranial hypertension due to cerebral venous sinus thrombosis within a mean delay of 2 years.
