[Brain abscess and Osler-Weber-Rendu syndrome: Do not forget to look for pulmonary arteriovenous malformations].

Introduction: Osler-Rendu-Weber syndrome or hereditary hemorrhagic telangiectasia affects between 1/5000 and 1/8000 people. It is characterized by presence of recurrent epistaxis, mucocutaneous telangiectasia and visceral arteriovenous malformations. It is a genetic disease with autosomal dominant transmission inducing an endothelial cells hyper-proliferation.

Estimation of optic nerve sheath diameter on an initial brain computed tomography scan can contribute prognostic information in traumatic brain injury patients.

Introduction: The aim of this study was to evaluate the prognostic value of optic nerve sheath diameter (ONSD) measured on the initial brain computed tomography (CT) scan for intensive care unit (ICU) mortality in severe traumatic brain injury (TBI) patients.

Methods: A prospective observational study of all severe TBI patients admitted to a neurosurgical ICU (over a 10-month period). Demographic and clinical data and brain CT scan results were recorded.

[Postoperative herpetic meningoencephalitis after lumbar surgery: a case report].

We report a case of a patient with an herpetic meningoencephalitis complicating lumbar surgery. A combination of factors like a postoperative sepsis, an abnormal MRI, and a positive viral PCR and culture made the diagnosis. A prolonged acyclovir treatment was employed with satisfactory results.
