L'exception sportive : champions noirs et culture coloniale (1900-1939)

4e de couv.: Comment la France a-t-elle été colonisée par son Empire ? En traitant du fait national tel qu'il a été modelé par l'idéologie coloniale, ce livre renverse les perspectives. Pour légitimer leurs lointaines conquêtes, la monarchie, l'empire et la république ont conçu, organisé, relayé auprès des Français une culture coloniale. Le cinéma et le théâtre, le sport et l'école, la littérature et la presse, les arts, la publicité, la chanson, sans oublier l'armée, les comités coloniaux, les expositions se sont chargés de diffuser quêtes scientifiques, fascinations exotiques, fiertés patriotiques ainsi qu'intérêts économiques et politiques. A l'heure où la France éprouve la difficulté de rassembler dans un destin commun des mémoires divisées, ce sont les grandes lignes de ce "passé qui ne passe pas" et les méandres d'une utopie coloniale que ce recueil retrace, de la première abolition de l'esclavage aux présents débats sur la "repentance". Une somme.

Nonanesthesiologist-administered propofol sedation: from the exception to standard practice. Sedation and monitoring trends over 20 years.

The practice of sedation, including monitoring practice for digestive endoscopy, continues to evolve throughout the world. In many countries, including Switzerland, there is a trend towards increased utilization of sedation during both routine and advanced endoscopic procedures. Sedation improves patient satisfaction with endoscopy and also improves the quality of the examination. In addition, a trend can be observed towards an increasing use of propofol as the preferred sedative drug. Here we review the latest published data from surveys describing sedation and monitoring practice in different countries and compare them with our own data from successive nationwide surveys among Swiss gastroenterologists over a period of 20 years. This development between these socioeconomically very similar Western industrialized countries, however, shows some unique and surprising differences. In Germany and Switzerland, propofol use has become increasingly widespread, in Switzerland even to the extent that during the last few years propofol has overtaken benzodiazepine sedation, with an absolute majority of Swiss gastroenterologists using it without the assistance of an anesthesiologist. In addition, the change in Switzerland reflects a successful generalization of nonanesthesiologist-administered propofol (NAAP) sedation from the hospital setting to private practice.

Artérite á cellules géantes et vitesse de sédimentation normale: plus qu'une exception [Giant cell arteritis and normal sedimentation rate: more than an exception!]

BACKGROUND: Giant cell arteritis (GCA) is a systemic segmental vasculitis of unknown etiology, typically affecting elderly patients. Elevated erythrocyte-sedimentation rate (ESR) is usually found in such patients. PATIENTS AND METHODS: One hundred and twenty three patients underwent temporal artery biopsy in our institution between 1977 and 1995. Among them, 66 (53.7%) biopsies were positive (i.e. histologic findings were very suggestive of GCA). The clinical charts from all patients with positive biopsies were retrieved and 47 were eligible for our study (inadequate data in 19 cases). RESULTS: Seven of the 47 patients with positive biopsies (15%) had a normal ESR and 70% (33/47 cases) had neuro-ophthalmic complications including anterior ischemic optic neuropathy, central retinal artery occlusion, choroidal ischemia and extraocular muscle and/or cranial nerve palsy (III, IV, VI). No differences were found between the groups with normal or elevated ESR as 87.5% (6/7 cases) of the group with normal ESR exhibited neuro-ophthalmic complications. CONCLUSIONS: ESR was normal in 15% of our GCA patients and these patients had the same frequency of neuro-ophthalmic complications as the GCA patients with elevated ESR. Thus, our study does not support the previous concept that patients with higher ESR are more at risk for neuro-ophthalmic complications. GCA with normal ESR is not rare and such patients should be investigated with other blood studies (C-reactive protein) and with fluorescein angiography.

Les traitements de l'ostéoporose (à l'exception de la substitution hormonale et de ses dérivés) [Treatment of osteoporosis (with the exception of hormone replacement and its derivates]

Calcium and vitamin D supplementation are warranted for the treatment of osteoporosis, when other specific drugs are used. Vitamin D supplementation is necessary when the plasma level of 25-hydroxy-vitamin D is below 30 nmol/l (12 pg/l) in order to avoid any increase of the plasma parathyroid hormone level. Bisphosphonates are the most widely drugs used. Recent advances will provide patients with a more convenient therapeutically equivalent alternative: the once-weekly oral dosing regimen and probably the possibility to give infusions at intervals of up to one year. Parathyroid hormone administered subcutaneously daily produced a dramatic increase of trabecular and cortical bone mineral density, and an important decrease of vertebral and nonvertebral fracture risk. Strontium is a new original drug, which stimulates bone formation, and inhibits bone resorption. It significantly improves trabecular and cortical bone mass. Calcitonin not only prevents the recurrence of vertebral fractures, but possibly could decrease hip fractures risk. Hydrochlorothiazide preserves the bone mineral density, and decreases nonvertebral fracture risk, as showed in epidemiological studies. Large clinical trials with statins therapy in appropriate populations are required to find out whether these drugs have any role in preventing fractures.
