Superficial white onychomycosis is characterized by opaque, friable, whitish superficial spots on the nail plate. We examined an affected halux nail of a 20-year-old male patient with scanning electron microscopy. The mycological examination isolated Trichophyton mentagrophytes. Abundant hyphae with the formation of arthrospores were found on the nail's surface, forming small fungal colonies. T...

We describe the case of an intrabronchial aspirated foreign body that caused a persistent right lower lobe infiltrate. A first fibreoptic bronchoscopy demonstrated a mass with tumour-like appearance in the right bronchus intermedias, but the bronchial biopsies and the cytological smears of the bronchial aspirate failed to reveal any malignancy. During a control fibreoptic bronchoscopy, we found...

Rhinosporidiosis caused by Rhinosporidium seeberii, a protistal microorganism, is endemic in several parts of India. Infection involves mucous membranes of the nose and paranasal sinuses and usually manifests as vascular friable polyps. A few cases of rhinosporidoisis have been reported from Delhi, in patients who were migrants from other states. The present case constitutes the first report of...

Résumé : Nous étudions l’asymptotique des fonctions sommatoires restreintes aux entiers friables de suites complexes en utilisant la méthode du cercle et des estimations précises sur les sommes d’exponentielles sur les friables. Les méthodes développées nous permettent d’obtenir une estimation du cardinal des couples de y-friables dont la somme est encore y-friable et, sous des hypothèses usuel...

Mt. Meru is Tanzania's second highest mountain and the ninth highest in Africa. The distribution and abundance of small mammals on this massif are poorly known. Here we document the distribution of shrews and rodents along an elevational gradient on the southeastern versant of Mt. Meru. Five sites were sampled with elevational center points of 1950, 2300, 2650, 3000, and 3600 m, using a systema...

It is proposed that many summit basins along the Aleutian Arc form from the clockwise rotation of blocks of the arc massif. Summit basins are arc-parallel grabens or half-grabens formed within the arc massif and are commonly located near or along the axis of late Cenozoic volcanism. Geomorphically, the Aleutian Arc appears to consist of contiguous rhombic blocks of varying size, tens to hundred...

Distinct competent layers are observed in the slopes of eastern Coprates Chasma, part of the Valles Marineris system on Mars. Our observations indicate that the stratigraphy of Coprates Chasma consists of alternating thin strong layers and thicker sequences of relatively weak layers. The strong, competent layers maintain steeper slopes and play a major role in controlling the overall shape and ...

L'œdème vulvaire massif est rare pendant la grossesse, mais requiert une attention particulière car il peut se greffer de complications maternelles et fœtales. Il peut être associé à plusieurs pathologies spécifiques ou non spécifiques à la grossesse dont le diagnostic fait appel obligatoirement à un interrogatoire et un examen clinique minutieux, puis à un bilan biologique standard. Le traitem...

The Madagascar-endemic microhylid genus Rhombophryne consists of a range of partly or completely fossorial frog species. They lead a poorly known, secretive lifestyle, and may be more diverse than previously thought. We describe a new species from the high altitude forests of the Sorata massif in north Madagascar with unusual characteristics for this genus; R. longicrus sp. n. has long, slender...

Patiente âgée de 21 ans adressée pour des abcès dentaires récidivants et victime depuis l'âge de six ans de multiples fractures des os des 4 membres. Elle a 2 frères ayant fait chacun des fractures osseuses multiples. Elle avait un retard staturo-pondéral et des déformations des os des membres inférieurs (A). Son morphotype se caractérisait par un aspect triangulaire au visage. L'examen de la b...
