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)
Hyperostosis frontalis interna (HFI) is manifested by the accretion of bone on the inner table of the frontal bone. Despite the vast literature on HFI, ambiguity exists as to its etiology, osteogenesis, demography, and history. This stimulated the present broad-scale study of HFI which included the evaluation of 1,706 early 20th century skulls (1,007 males(More)
This study was conducted to determine whether individual bony lesions are specific for recognizing multiple myeloma and thereby distinguish it from metastatic cancer and leukemia. The lytic skeletal lesions of multiple myeloma are characterized by sharply defined, spheroid lesions. They have smooth borders and effaced/erased trabeculae. Unique spheroid(More)
The ubiquitous nature of spinal ligamentous calcification in the paleontologic record provides additional support for the suggestion that DISH is a protective phenomenon rather than a musculoskeletal disease, and perhaps represents a normal variant. Clinical assessment of contemporary DISH suggests a protective mechanical effect, paradoxically associated(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)
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)
Spondyloarthropathy was observed in 25 (2.8%) of 895 preserved canid museum specimens and was catalogued by species. The associated skeletal alterations in canids are indistinguishable grossly and physiologically from those in humans with spondyloarthropathy of the reactive type. Rate of affliction was independent of captive or wild-caught status or gender.(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)
