Design and realization of a multi-coil array for B field control in a compact 1.5T head-only MRI scanner.

Purpose: To design and implement a multi-coil (MC) array for B field generation for image encoding and simultaneous advanced shimming in a novel 1.5T head-only MRI scanner.

Methods: A 31-channel MC array was designed following the unique constraints of this scanner design: The vertically oriented magnet is very short, stopping shortly above the shoulders of a sitting subject, and includes a window for the subject to see through.

Tibial developmental field defect in valproic acid embryopathy: Report on three cases.

Prenatal exposure to valproic acid (VA) is associated with an increased risk of congenital malformations, especially limb defects like radial ray defects. Tibial developmental field defect in VA embryopathy remains exceptional. We report on three patients presenting with tibial hypo/aplasia associated with either femoral bifurcation or radial ray defect following prenatal exposure to VA.

[Subgaleal hematoma in 2 neonates].

Subgaleal hematoma in the newborn infant is rare, occurs early, and often bears serious consequences. We report on 2 subacute cases of bruising of the scalp that occurred following the use of a suction cup. Emergency treatment consisted of a transfusion of packed red blood cells and fresh frozen plasma.

Mother-to-child transmission of Chikungunya virus infection.

Background: In 2005-2006 Reunion Island experienced a massive outbreak of chikungunya, a mosquito-borne alphavirus infection. During this epidemic, early neonatal cases were observed with a highly probable mother-to-child transmission.

Methods: A retrospective descriptive study was conducted in 5 neonatal medicine departments.
