Serum copper, zinc and selenium levels in Tunisian patients with Parkinson's disease.

Background: Parkinson's disease (PD) is a progressive neurodegenerative disorder. The etiology of this disease is still not fully clear, but free radicals have been proposed to cause neuronal injury. Metals play a key role in the intracellular oxidative balance.

[Tuberous sclerosis and intracranial aneurysms: a rare association].

Introduction: Tuberous sclerosis is an autosomal dominant inherited phakomatosis. It is associated with a wide variety of central nervous system abnormalities, but intracranial aneurysms are rare.

Case Report: We report a 34-year-old patient fulfilling the diagnostic criteria of tuberous sclerosis in association with intracranial aneurysm.

[Multiple cranial nerve involvement: consider the diagnosis of cephalic tetanus. A case report and review of the literature].

Introduction: Cephalic tetanus is the most serious form of localized tetanus. It associates trismus with impairment of one or more cranial nerves. It was a rare condition, whose diagnosis can raise several problems.

A clinical and magnetic resonance spectroscopy study of a brain tumor in a patient with segmental neurofibromatosis.

Introduction: Segmental neurofibromatosis 1 (segmental NF-1) is a rare genodermatosis caused by somatic mutations in the NF-1 gene. It consists of localized characteristic skin lesions. A serial study using magnetic resonance imaging (MRI) and magnetic resonance spectroscopy (MRS) of a brain tumor in a 16-year-old patient with segmental NF-1 is reported.
