ABSTRACT
We report a case of staphyloccocal scalded skin syndrome due to an oxacillin-susceptible Staphylococcus aureus in an 81-year-old woman. The patient was admitted to the emergency room with arthritis of the left shoulder, ten days after an intra-articular injection of corticosteroids. The shoulder's puncture showed a purulent liquid and gram positive cocci in cluster suggesting the presence of Staphylococcus sp. on the Gram-stain. The culture confirmed the identification of an oxacillin-susceptible Staphylococcus aureus. Before administration of any dose of oxacillin, blisters appeared on the skin, that quickly ruptured, particulary in areas of friction. The exfoliated areas were extensive and resolution of all the lesions was reached after 3 weeks. The skin biopsy showed superficial epidermolysis confirming the diagnosis. Staphyloccocal scalded skin syndrome is usually described in neonates and young children, often in outbreaks. Few cases have been reported in adults, most often associated with severe underlying diseases. The mortality rate is low in children but can reach almost 60% in adults. The most important diagnosis to exclude is Lyell's syndrome which can be done by the skin biopsy.

Fluorine was determined in the iliac crest bones of patients and in ribs collected from post-mortem investigations by particle-induced gamma-ray emission based on the 19F(p,p'gamma)19F reaction, using 2.0/2.5 MeV protons. The results indicate that for 68% of the human samples the F concentration is in the range 500-1999 microg g(-1). For comparison purposes fluorine was also determined in some animal bones; in some animal tissues lateral profiles of fluorine were measured.

Oxygen at trace level in calcium fluoride was determined by instrumental deuteron activation analysis based on the 16O(d,n)17F reaction. The irradiations were performed with 2.5 MeV deuterons for 60 s at currents ranging from 300 to 500 nA. The results obtained for powders and single crystals were compared.
ABSTRACT
Coral has been used for the last ten years as bone substitution in the body because of its mechanic and osteoconductor properties. Our primary studies have shown, for the first time, the quantitative behaviour of the atomic components.
