The impact of climate on the vector behaviour of the worldwide dog tick Rhipicephalus sanguineus is a cause of concern. This tick is a vector for life-threatening organisms including Rickettsia rickettsii, the agent of Rocky Mountain spotted fever, R. conorii, the agent of Mediterranean spotted fever, and the ubiquitous emerging pathogen R. massiliae.

BACKGROUND Neuromyelitis optica (NMO) is an inflammatory disease associated with optic neuritis and myelitis. Recently, several studies showed that optical coherence tomography (OCT) could be an interesting method for the evaluation of disease severity; however, to date there are no studies with a longitudinal follow-up of visual function in NMO. The aim of(More)
INTRODUCTION Multiple sclerosis is a common disabling progressive neurological disorder. Axonal loss is thought to be a likely cause of persistent disability after a multiple sclerosis relapse. Retinal nerve fiber layer (RNFL) imaging by optical coherence tomography (OCT) seems to be a non-invasive way of detecting optical axonal loss following optic(More)
BACKGROUND Neuromyelitis optica (NMO) is an inflammatory disease with combined features of optic neuritis and myelitis. This pathologic entity may induce severe disability, including visual loss and paraplegia. Other than clinical follow-up, there is no marker for severity of the disease. OBJECTIVES To evaluate the use of optical coherence tomography(More)
PURPOSE To analyze clinical and paraclinical characteristics of recurrent isolated optic neuropathy. PATIENTS and method: In three university hospitals (Montpellier, Nimes, and Strasbourg), between October 2005 and September 2006, the charts of patients with corticosensitive recurrent isolated optic neuropathy and normal cerebral magnetic resonance(More)
INTRODUCTION Mild ophthalmoparesis can be seen in oculopharyngeal muscular dystrophy (OPMD). METHODS Orthoptic analysis included assessment of phoria/tropia, eye excursion, saccades, pursuit, stereoacuity, and Hess-Lancaster screen test. Video-oculography included fixation, horizontal and vertical saccades, and pursuit. RESULTS Orthoptic abnormalities(More)
A 72-year-old patient presented with a left-sided Wallenberg syndrome, including thermoalgic anesthesia associated with severe itching leading to ulcerations in the left trigeminal area (Fig. 1). Few cases of so-called ‘‘neurotrophic’’ ulcerations in the trigeminal area (sometimes with corneal involvement) following lateral medullary infarction have been(More)
