Seronegative acute encephalitis following COVID-19 vaccines: a case series of an overlooked diagnosis with literature review.

Purpose: Autoimmune encephalitis is a neurological emergency of new-onset altered mental status, caused by an exaggerated immune-mediated response that targets the central nervous system. Autoimmune encephalitis has become an emerging differential diagnosis, when a classical infection cannot explain neurological symptoms. Displaying overlapping clinical presentations, ranging from the insidious onset of cognitive deficiency to more severe forms of encephalopathy with refractory seizures, autoimmune encephalitis can be challenging for clinicians.

External validations of the ABCD2 score in prediction of stroke risk after transient ischemic attack. A Tunisian hospital-based cohort study.

Background And Purpose: Identification of patients with high risk of stroke after transient ischemic attack (TIA) could be helpful to optimize stroke prevention. We aimed to externally validate the ABCD2 score for the prediction of stroke after TIA in a Tunisian population.

Methods: We conducted a retrospective observational study of consecutive patients admitted for TIA in four university hospitals in Tunisia.

Catatonia in patients with dementia: a case report.

Catatonia occurring as part of a clinical picture of dementia has been reported with almost all types of dementia. It remains under-diagnosed in older adults and those with dementia. We review a case of a young patient admitted in our psychiatric department for catatonia and after efficient treatment with Lorazepam, assessment revealed a dementia.

Psychiatric disorders in the acoustic neuroma: about a case.

Neurofibromatosis type 2 (NF2) is a rare autosomal dominant disorder characterized by formation of central nervous system tumors. They are associated to significant morbidity due to multiple problems such as hearing loss that can lead to many psychiatric disorders.

Primary Hyperparathyroidism and Hyperthyroidism in a Patient with Myotonic Dystrophy: A Case Report and Review of the Literature.

Various endocrine manifestations are commonly described in myotonic dystrophy (MD), including primary hypogonadism, diabetes mellitus, and thyroid and parathyroid dysfunction. We describe a 46-year-old woman with a family history of MD with her son. She was diagnosed with cardiac arrhythmia and required the implantation of a pacemaker.

Seizures and movement disorders induced by hyperglycemia without ketosis in elderly.

Background: Non-ketotic hyperglycemia (NKHG) may increase the probability of seizures and movement disorders.

Methods: We describe a series of 14 elders admitted for seizures and movement disorders linked to NKHG.

Results: Twelve patients developed motor seizures and two others movement disorders.

Facial cellulitis revealing choreo-acanthocytosis: a case report.

We report a 62 year-old-man with facial cellulitis revealing choreo-acanthocytosis (ChAc). He showed chorea that started 20 years ago. The orofacial dyskinisia with tongue and cheek biting resulted in facial cellulitis.

Cerebral Aneurysms: A Rare Feature of Behçet's Disease-A Case Report and Review of the Literature.

Behçet's disease (BD) is a multisystem vascular inflammatory disease with several clinical manifestations. Intracranial aneurysms are an extremely rare but nevertheless severe complication of BD. We report a case of a 44-year-old man.

48XXYY Syndrome in an Adult with Type 2 Diabetes Mellitus, Unilateral Renal Aplasia, and Pigmentary Retinitis.

A 45-year-old male was referred for diabetes mellitus. Clinical examination found a family history of multiple precocious deaths, strong consanguinity, personal history of seizures during childhood, small testicles, small penis, sparse body hair, long arms and legs, dysmorphic features, mental retardation, dysarthria, tremor, and mild gait ataxia. Investigations found pigmentary retinitis, metabolic syndrome, unilateral renal aplasia, and hypergonadotropic hypogonadism, and ruled out mitochondrial cytopathy and leucodystrophy.

Maternally inherited Leigh syndrome: T8993G mutation in a Tunisian family.

Leigh syndrome is a genetically heterogeneous, neurodegenerative disorder that predominantly affects children and leads to death within months or years. Mutations causing this disease have been found in both mitochondrial and nuclear DNA. The present report describes a Tunisian family with a maternally inherited Leigh syndrome harboring the mitochondrial T8993G mutation in the ATPase 6 gene.
