[Bilateral acute retinal necrosis syndrome associated with meningoencephalitis caused by herpes simplex virus 2. A case report].

Introduction: Acute retinal necrosis syndrome (ARN syndrome) is a rare viral disease with a poor prognosis in most cases. It is characterized by substantial ocular inflammation with progressive retinal necrosis, occlusive vasculitis and sometimes extraocular features.

Case Report: We report the case of a 62-year-old woman who was referred for a suspicion of a stroke.

[Activity and epidemiology in an ophthalmological emergency center].

Purpose: To investigate the numbers and characteristics of patients with ophthalmological emergencies presenting at a general hospital.

Methods: Retrospective analysis of ophthalmological emergencies over 11 years included comparison with demographic changes and, over the last 2 years, analysis of the patients treated (age, sex, and pathology, according to 23 preselected pathologies). Ophthalmological examinations were done by a senior ophthalmologist.

[Carbohydrate-deficient glycoprotein syndrome and progression in electrophysiological results].

Purpose: To document the progression of clinical and electrophysiological abnormalities in an infant with carbohydrate-deficient glycoprotein syndrome type Ia (CDGS Ia) over a period of 5 years.

Patient And Methods: A 12-month-old male underwent clinical ophthalmic and electrophysiological examination at the age of 1, 2, and 6 years. Neurological examination, magnetic resonance imaging of the brain and a genetic study were also undertaken.

Primary trigeminal afferents to the vestibular nuclei in the rat: existence of a collateral projection to the vestibulo-cerebellum.

Projections from the mesencephalic trigeminal nucleus to the vestibular nuclei were analyzed using retrograde and anterograde tracing methods. The results show that neurons in the caudal part of the trigeminal mesencephalic nucleus project mainly to the medial, inferior and lateral vestibular nuclei and moderately to the peripheral part of the superior vestibular nucleus. Using the double-labeling technique we demonstrate that individual neurons of the mesencephalic nucleus send collaterals to the vestibular nuclei and the vestibulo-cerebellum.
