Register-based incidence of multiple sclerosis in Brittany (north-western France), 2000-2001.

Objectives: To report on multiple sclerosis (MS) incidence in Brittany, north-western France.

Materials & Methods: From 2000, we set up a population-based register for patients presenting a putative incident MS (PIMS), that is first symptoms compatible with MS onset. We used 3 medical sources of case ascertainment (neurologists, CSF, regional MS-Clinic).

Absorption cross-sections of atmospheric constituents: NO2, O2, and H2O.

Absorption spectroscopy, which is widely used for concentration measurements of tropospheric and stratospheric compounds, requires precise values of the absorption cross-sections of the measured species. NO(2), O(2) and its collision-induced absorption spectrum, and H(2)O absorption cross-sections have been measured at temperature and pressure conditions prevailing in the Earth's atmosphere. Corrections to the generally accepted analysis procedures used to resolve the convolution problem are also proposed.

[Dorsal medulla oblongata stroke after a wasp sting].

Introduction: Although wasp stings can cause local reactions such as pain, flare, edema, swelling and severe reactions, including anaphylaxis; neurological vascular complications are rare.

Case Report: We report a case of a 36-year-old male who developed focal neurological symptoms after a wasp sting. The brain MRI showed an infarct in the left dorsal medulla.

Effects of nicardipine and clonidine on cognitive functions and electroencephalography in hypertensive patients.

The aim of this study was to investigate the cognitive and electroencephalography (EEG) short-term effects of a calcium antagonist, nicardipine, compared to placebo and clonidine (which, having known sedative effects, acted as a negative control) for 15 days in elderly hypertensive patients with memory complaints. Nicardipine and clonidine were compared with placebo in a double-blind, randomized, three-way cross-over controlled study after a 2-week placebo run-in period. This was a phase II clinical study carried out on out-patients in a single research centre.
