The oldest fossil hippopotamus (Hippopotamus laloumena) of Madagascar (Belobaka, Mahajanga Province)

International audienceThe Upper Pleistocene site Belobaka XVII (about 20,000 years) has yielded some Hippopotami remains included in a very hard breccia. Among this material two lower premolars, a juvenile calcaneus, two juvenile metatarsals and a first abaxial phalange have been cleaned and can be studied. They belong to Hippopotamus laloumena Faure and Guerin, 1990, allowed us to know for the first time the P/2 and P/3 of that species and confirm its validity. Belobaka is then the third Malagasyan site where H. laloumena has been found, and the first which yielded Pleistocene hippopotami remain

Aramon (Gard). La nécropole du Ier siècle avant notre ère

During excavations in 1975 the necropolis of Le Paradis at Aramon could be only partially explored ; nevertheless the twelve groups of graves now available form a milestone of primary importance for the funerary archaeology of southern Gaul. A cremation tomb from the first half of the first century A.D. excavated north of Aramon is described at the same time. The tombs of Le Paradis are dated from the second quarter of the Ist century B. C. to the first quarter of the Ist century A.D. and are here analysed in detail, concerning both the funeral practices (progressive appearance of burnt bones taken from the pyre, development of categories of grave offerings) and the chrono-cultural aspect : function of the different objects placed in the grave, criteria for their choice and social implications. Considered to be the mirror image of the agglomeration situated on the neighbouring hill-top and no doubt stretching to the foot of the massif, on the site of the mediaeval and modern towns, the necropolis of Aramon provides the first clues about of the romanization of this Rhône valley community in the course of the Ist century B.C.Fouillée en 1975, la nécropole du Paradis à Aramon n'a pu être explorée que partiellement ; les douze ensembles sépulcraux disponibles aujourd'hui constituent néanmoins un jalon de première importance pour l'archéologie funéraire de la Gaule méridionale. Une tombe à incinération de la première moitié du Ier s. de notre ère fouillée au nord d'Aramon est également décrite par la même occasion. Datées du deuxième quart du Ier s. av. J.-C. au premier quart du Ier s. de notre ère, les tombes du Paradis font ici l'objet d'une analyse détaillée, tant du point de vue des pratiques funéraires (apparition progressive d'un dépôt d'os brûlés prélevé sur le bûcher, évolution des classes de mobilier d'offrande) que sous l'aspect chrono-culturel : fonction des différents objets déposés dans la sépulture , critères de choix et implications sociales . Considérée comme un miroir de l'agglomération qui occupait la hauteur voisine et s'étendait sans doute au pied du massif, à l'emplacement de la ville médiévale et moderne, la nécropole d'Aramon apporte les premiers éléments d'appréciation sur la romanisation de cette communauté rhodanienne dans le courant du Ier s. avant notre ère.Genty Pierre-Yves, Feugère Michel, Gardeisen Armelle, Janin Thierry, Richard Jean-Claude.

Automatic recognition system of aquatic organisms by classical and fluorescence microscopy

International audienceBlooming of algae and more generally phytoplankton in water ponds or marine environments can lead to hyper eutrophication and lethal consequences on other organisms. The selective recognition of invading species is investigated by automatic recognition algorithms of optical and fluorescence imaging. On one hand, morphological characteristics of algae of microscopic imaging are treated. The image processing lead to the identification the genus of aquatic organisms and compared to a morphologic data base. On the other hand, fluorescence images allow an automatic recognition based on multispectral data that identify locally the ratio of different photosynthetic pigments and gives a unique finger print of algae. It is shown that the combination of both methods are useful in the recognition of aquatic organisms

Duration of adrenal inhibition following a single dose of etomidate in critically ill patients.

International audienceOBJECTIVE: To determine the incidence and duration of adrenal inhibition induced by a single dose of etomidate in critically ill patients. DESIGN: Prospective, observational cohort study. SETTING: Three intensive care units in a university hospital. PATIENTS: Forty critically ill patients without sepsis who received a single dose of etomidate for facilitating endotracheal intubation. MEASUREMENTS AND MAIN RESULTS: Serial serum cortisol and 11beta-deoxycortisol samples were taken at baseline and 60 min after corticotropin stimulation test (250 microg 1-24 ACTH) at 12, 24, 48, and 72 h after etomidate administration. Etomidate-related adrenal inhibition was defined by the combination of a rise in cortisol less than 250 nmol/l (9 microg/dl) after ACTH stimulation and an excessive accumulation of serum 11beta-deoxycortisol concentrations at baseline. At 12 h after etomidate administration, 32/40 (80%) patients fulfilled the diagnosis criteria for etomidate-related adrenal insufficiency. This incidence was significantly lower at 48 h (9%) and 72 h (7%). The cortisol to 11beta-deoxycortisol ratio (F/S ratio), reflecting the intensity of the 11beta-hydroxylase enzyme blockade, improved significantly over time. CONCLUSIONS: A single bolus infusion of etomidate resulted in wide adrenal inhibition in critically ill patients. However, this alteration was reversible by 48 h following the drug administration. The empirical use of steroid supplementation for 48 h following a single dose of etomidate in ICU patients without septic shock should thus be considered. Concomitant serum cortisol and 11beta-deoxycortisol dosages are needed to provide evidence for adrenal insufficiency induced by etomidate in critically ill patients

Diagnostic accuracy of ultrasonography in the acute assessment of common thoracic lesions after trauma.: Ultrasonography in thoracic trauma

International audienceBACKGROUND: The accuracy of combined clinical examination (CE) and chest radiography (CXR) (CE + CXR) vs thoracic ultrasonography in the acute assessment of pneumothorax, hemothorax, and lung contusion in chest trauma patients is unknown. METHODS: We conducted a prospective, observational cohort study involving 119 adult patients admitted to the ED with thoracic trauma. Each patient, secured onto a vacuum mattress, underwent a subsequent thoracic CT scan after first receiving CE, CXR, and thoracic ultrasonography. The diagnostic performance of each method was also evaluated in a subgroup of 35 patients with hemodynamic and/or respiratory instability. RESULTS: Of the 237 lung fields included in the study, we observed 53 pneumothoraces, 35 hemothoraces, and 147 lung contusions, according to either thoracic CT scan or thoracic decompression if placed before the CT scan. The diagnostic performance of ultrasonography was higher than that of CE + CXR, as shown by their respective areas under the receiver operating characteristic curves (AUC-ROC): mean 0.75 (95% CI, 0.67-0.83) vs 0.62 (0.54-0.70) in pneumothorax cases and 0.73 (0.67-0.80) vs 0.66 (0.61-0.72) for lung contusions, respectively (all P < .05). In addition, the diagnostic performance of ultrasonography to detect pneumothorax was enhanced in the most severely injured patients: 0.86 (0.73-0.98) vs 0.70 (0.61-0.80) with CE + CXR. No difference between modalities was found for hemothorax. CONCLUSIONS: Thoracic ultrasonography as a bedside diagnostic modality is a better diagnostic test than CE and CXR in comparison with CT scanning when evaluating supine chest trauma patients in the emergency setting, particularly for diagnosing pneumothoraces and lung contusions
