Pulmonary Langerhans cell histiocytosis is a rare interstitial lung disease. It's morbidity is estimated at 4-5 person per million. The multiformity--from benignity to severe--brings difficulties during the process of diagnosis. The authors describe a case of 48-year-old woman with a benign pulmonary lung histiocytosis. It is underlined the diagnostic quality of high resolution tomography and b...

Since 2004, the satellite-borne Ozone Mapping Instrument (OMI) has observed sulphur dioxide (SO2) plumes during both quiescence and effusive eruptive activity at Soufrière Hills Volcano, Montserrat. On average, OMI detected a SO2 plume 4-6 times more frequently during effusive periods than during quiescence in the 2008-2010 period. The increased ability of OMI to detect SO2 during eruptive peri...

Pre-eruptive intracoronal resorption is a lesion often located within the dentin, adjacent to the dentin-enamel junction, in the occlusal aspect of the crown. As the lesions resemble caries, they are often referred as "pre-eruptive caries." The purpose of this case report was to describe the diagnosis and treatment of a permanent molar with pre-eruptive intracoronal resorption and to elaborate ...

Studies have shown that the variability of precipitation depends primarily of climatic factors, wind, temperature, and atmospheric pressure, however in the past twenty years the continuous eruptive process of volcano Tungurahua has been a natural factor that contributed to the variability of precipitations in short term and to the extension of the watershed of Ambato River. To incorporate the e...

Bartonellosis, or Carrion's Disease, is an endemic and reemerging disease in Peru and Ecuador. Carrion's Disease constitutes a health problem in Peru because its epidemiology has been changing, and it is affecting new areas between the highland and the jungle. During the latest outbreaks, and previously in endemic areas, the pediatric population has been the most commonly affected. In the pedia...

Severe skin involvement complicated a case of sinus histiocytosis with massive lymphadenopathy in a young Malay girl. The clinical and histological features of this rare manifestation are described.

We present the case of a 10-year-old girl with a six months history of disseminated asymptomatic, brown pigmented macules on the trunk and proximal parts of the extremities. The clinical picture, histological findings, and the course of disease were similar to those of idiopathic eruptive macular pigmentation. The cutaneous lesions gradually disappeared over the next two years without any treat...

Grande Ronde Basalt (GRB) lavas represent the most voluminous eruptive pulse of the Columbia River-Snake River-Yellowstone hotspot volcanism. With an estimated eruptive volume of 150,000 km, GRB lavas form at least 66% of the total volume of the Columbia River Basalt Group. New Ar/Ar dates for GRB lavas reveal they were emplaced within a maximum period of 0.42 ±0.18 My. A well-documented strati...
