Urinary tract infections in hospital pediatrics: many previous antibiotherapy and antibiotics resistance, including fluoroquinolones.

Objective: We studied antibiotic resistance in pediatric UTIs and we evaluated the impact of antibiotic exposure in the previous 12 months, very little French data being available for this population.

Methods: We conducted a multicenter prospective study including children consulting for, or admitted in 2 hospitals. Prior antibiotic exposure was documented from their health record.

[Benefit of seasonal use of a rapid diagnosis of influenza virus in a paediatric emergency unit].

Influenza virus infections are current in viral infections of childhood. The quick test is now available and we want to assess its clinical and economical benefit through an unicentric study and during two seasons of influenza pandemic. An hospitalization avoided due to a quick test is equivalent to 20 to 30 general practitioner fixes fees.

[Neurosurgical embryology. Part 8: Post-natal angiogenesis and remodeling].

Post-natal angiogenesis (microvascular proliferation) and remodeling (modifications of diameter and wall thickness) occur in various physiological circumstances including adaptation to exercise or wound healing. The formation of a new vessel is submitted to the combinative action of growth factors. New endothelial cells migrate, proliferate, differentiate and attract pericytes and future smooth muscle cells to create the new vessel.

Adaptive common carotid arteries remodeling after unilateral internal carotid artery occlusion in adult patients.

Objective: This study was undertaken in human adults to examine modifications in common carotid internal diameter (ID), intima-media thickness (IMT), cross-sectional area (CSA) and wall shear stress (WSS) occurring both on the ipsilateral side of an internal carotid artery (ICA) occlusion and on the non-occluded contralateral side.

Methods: Seventeen patients with unilateral ICA occlusion had repeated echo-Doppler examinations during 1 year and were compared to 12 volunteers with control non-occluded common carotid arteries (CCA).

Results: The cause of ICA occlusion was atherosclerosis in nine patients, dissection in five, and undetermined in three.
