Global Tracking and Quantification of Oil and Gas Methane Emissions from Recurrent Imagery.

Methane (CH) emission estimates from top-down studies over oil and gas basins have revealed systematic underestimation of CH emissions in current national inventories. Sparse but extremely large amounts of CH from oil and gas production activities have been detected across the globe, resulting in a significant increase of the overall oil and gas contribution. However, attribution to specific facilities remains a major challenge unless high-spatial-resolution images provide sufficient granularity within the oil and gas basin.

[Seasonal outbreak of enteroviral meningitis during summer 2005: experience of a French pediatric unit].

Objective: To describe the clinical and biological characteristics of children presenting with enteroviral (EV) meningitis in a French paediatric unit during summer 2005.

Methods: Retrospective study of children with EV meningitis from May to September 2005, diagnosed by PCR and/or viral culture in cerebrospinal fluid (CSF), serum or throat.

Results: We reported 99 cases of EV meningitis (96 confirmed and 3 probable).

[Pseudomonas aeruginosa and cystic fibrosis: non-antibiotic strategy].

The Pseudomonas aeruginosa bronchopulmonary infection is, when chronical, a poor prognosis factor for cystic fibrosis children. The higher life expectancy is partly linked to the progresses of the antipseudomonal antibiotherapy: treatment modulated to the stage of infection; possible use of nebulized and oral (ciprofloxacin) antibiotics. But the antipseudomonal strategy does not limit to the antibiotherapy.

[Acute infectious diarrhea].

Acute infectious diarrhea has various causes: bacterial diarrhea with invasive or toxigenic mechanisms, especially frequent in hot regions and in travelers; viral diarrheas, frequent and cosmopolitan in children but also adults; and parasitic diarrhea, less frequent, and generally in subtropical areas. The major concerns involve the risk of complications, essentially dehydration and malnutrition, especially in vulnerable patients: young children, the elderly, and patients with immunosuppression, for whom rehydration is urgent. Diagnosis of diarrhea requires clinical assessment and history: underlying illnesses, severity of symptoms, presence and extent of dehydration and other clinical symptoms, travel history, known outbreaks, and pathogenic mechanism (invasive or toxigenic).
