X-ray absorption holography.

The transmission of monochromatic x rays through a CoO single crystal was measured for different orientations of the sample. The small variations in the linear absorption coefficient were considered as a hologram and the real-space image of the local atomic environment was successfully reconstructed. The holographic signal constituted about 1% of the detected intensity. Besides other benefits, the use of the absorption holography can increase the signal-to-background ratio by more than 1 order compared with the fluorescence holography.

[Psychosocial dwarfism].

A 4 year old girl with psychosocial dwarfism showed hepatomegaly, abdominal distension and behavioral disturbances. Laboratory tests revealed a reversible elevation of serum liver enzymes and a reversible partial growth hormone deficiency. The child's family was characterised by severe social problems and all signs of a depriving and child abusing environment. All pathologic findings were reversed by removing the child from her depriving family background. This case demonstrates that psychosocial dwarfism represents an aspect of child abuse (battered child syndrome).
