Isolation of type 5 capsular polysaccharide from Staphylococcus aureus.

Clinical surveys have indicated the predominance of type 5 and type 8 capsular polysaccharides among clinical isolates of Staphylococcus aureus. The type 5 capsular polysaccharide was extracted from three clinical isolates of S. aureus grown on solid media, and purified by ion exchange chromatography and gel filtration. Chemical analysis showed that the type 5 capsular polysaccharide is composed of N-acetylfucosamine and N-acetylhexosaminuronic acid. Immunodiffusion and 13C nuclear magnetic resonance experiments showed that the type 5 capsular polysaccharide is both immunologically and chemically distinct from the type 8 capsular polysaccharide and the teichoic acid of S. aureus.

Adductor and psoas release for subluxation of the hip in children with spastic cerebral palsy.

Forty-four hips in 22 children between the ages of 2.0 and 6.0 years (mean, 4.0 years) with cerebral palsy were followed-up prospectively for a minimum of 5 years. Of the 44 hips studied preoperatively, 20 were radiologically normal, 24 were subluxed, and one was dislocated. Five years postoperatively, 39 hips were normal, five were subluxed, and none was dislocated. None of the 27 hips that were normal preoperatively either subluxed or dislocated during the study period. Nineteen of the subluxed hips became normal, and five remained subluxed. Adductor and psoas releases prevent hip subluxation and provide a measure of protection to the opposite hip.

Imported viral haemorrhagic fever with a potential for person-to-person transmission: review and recommendations for initial management of a suspected case in Belgium.

Viral haemorrhagic fevers are caused by a wide range of viruses. There are 4 types of viruses well known to spread from person to person and able to cause nosocomial outbreaks with a high case fatality rate: an arenavirus (Lassa fever and more exceptionally the Junin and Machupo virus), a bunyavirus (Crimean-Congo haemorrhagic fever) and the Filoviridae (Ebola and Marburg viruses). So far there have been only a limited number of imported cases of viral haemorrhagic fever in industrialized countries. In recent years an increasing number of outbreaks of filovirus infections have occurred in Africa and in 2000 5 cases of Lassa fever were brought from Sierra Leone to Europe. Therefore European physicians should consider the possibility of a viral haemorrhagic fever in an acutely ill patient just returning from Africa or South-America with fever for which there is no obvious cause. Such patients should be questioned for risk factors for viral haemorrhagic fever. Using universal precautions for handling blood and body fluids and barrier nursing techniques there is little risk that if a patient with viral haemorrhagic fever arrives in Belgium there will be secondary cases.

Thoracic lordosis in idiopathic scoliosis.

Lordosis, a significant aspect of thoracic scoliosis, is difficult to assess with routine clinical radiographs. Computerized analysis of 138 sets of standardized anteroposterior and lateral radiographs served to elicit the three-dimensional structure of scoliosis. Spinal curvatures in the usual anatomic planes and in the sagittal and frontal planes of the apical vertebrae were measured. Lordosis was present in 35% of curves greater than or equal to 40 degrees and in 50% of curves greater than 49 degrees. Lordosis may be a contraindication for brace treatment.

Modifications of collagens in the course of inflammatory tracheal stenoses.

A comparison was made between the biochemical and histological properties of collagens contained in samples of normal tracheas obtained at autopsy or of stenosed tracheas obtained during surgery. The amounts of total collagen solubilized by pepsin was increased seven times in the pathological samples, and the proportion of cartilage type II collagen decreased by about one half, being replaced by type I collagen, whose ratio was increased five times. Microscopic studies confirmed that cartilage underwent a degenerative process and was progressively infiltrated by fibrils of interstitial collagen.
