In order to assess the presence of tuberculosis in Pleistocene bison and the origin of tuberculosis in North America, 2 separate DNA extractions were performed by 2 separate laboratories on samples from the metacarpal of an extinct long-horned bison that was radiocarbon dated at 17,870+/-230 years before present and that had pathological changes suggestive(More)
The present study addresses the specificity of lytic osseous impact for distinguishing among metastatic cancer, tuberculosis, and fungal disease. Osseous impact is used in this manuscript as a convention to describe the macroscopic appearance of defleshed bones affected by the disease. Osseous changes in the skeleton of a 47-year-old black male, diagnosed(More)
Diploic veins (Canales diploicae), which were identified in dogs by Dupuytren more than 200 years ago (Hecker [1845] Die anatomische Verhaltnisse und Krankheiten der Venae diploicae und Vasa emissaria. Erfahrungen und Abhandlungen im Gebiete der Chirurgie und Augenheilkunde. Erlangen), have remained inadequately understood and scantily referenced in the(More)
Uncertainties as to the nature and implications of osteoarthritis and calcium pyrophosphate deposition disease (CPPD) in primates were subject to critical review through examination of 153 prosimians and 1,250 Old World non-prosimian primates. Osteoarthritis, calcium pyrophosphate deposition disease, and infectious arthritis/osteomyelitis were relatively(More)
Characterization of the nature and skeletal distribution of gout was accomplished in a Chamoru (Chamorros) population with predilection to the disease. Uniform excavation by the gouty diathesis produces a punched-out appearance to these predominantly monarticular lesions. The lesion is distinct from that seen in rheumatoid arthritis, spondyloarthropathy, or(More)
STUDY DESIGN Thoracolumbar facet and interfacet linear dimensions were measured and analyzed. OBJECTIVE To characterize and analyze the thoracolumbar facet and interfacet size and shape in relation to gender, ethnic group, and age and to detect the extent of normal facet tropism along the thoracolumbar spine. SUMMARY OF BACKGROUND DATA Knowledge on(More)
OBJECTIVE To determine the relationship of what has been called pre-Columbian Old World rheumatoid arthritis (RA) to the RA identified in pre-Columbian North America. METHODS All published claims of pre-Columbian Old World RA were reviewed against the established North American standard for its recognition in archeologic sites. Those characteristics(More)
Erosive changes and syndesmophyte formation, characteristics of spondyloarthropathy, were present in 79/2906 skeletons in the Todd Collection. Holistic assessment of this defined population allowed it to be distinguished from rheumatoid and other erosive forms of arthritis. Characterization of the nature and distribution of osseous alterations in a(More)
