Study of ancient disease (paleopathology) is a powerful tool for understanding lifestyle and population dynamics, as well as the history of disease in antiquity. The major premise of paleopathology is that diagnoses of conditions of living animals…
The etiology of arthritis in Hyaenidae has been a subject of conjecture. While osteoarthritis has been considered, the observation of an erosive arthritis prompted a systematic survey of museum specimens to define its nature and frequency.…
Assessment of laboratory values is an important function of nursing practice. Rheumatologic laboratory assessment, in particular, can be complex because few findings are actually pathognomonic. This article provides a perspective on an interpretive…
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…
Calcium pyrophosphate deposition disease (CPPD), a form of crystalline arthritis, has a unique distribution in the Early to Middle Archaic Periods (3000 to 8000 years before the present) of North America, contrasting with the generalized geographic…
Shared characteristics and concurrent occurrence of rheumatoid arthritis (RA) and spondyloarthropathy in contemporary populations have compromised development of clear diagnostic criteria for distinguishing them. Although modern populations contain…
The osseous appearance, skeletal distribution, and distinguishing features of calcium pyrophosphate deposition disease (CPPD) were delineated in a population of 2906 contemporary defleshed skeletons. The limitations of routine x-ray and clinical…
Sixty skeletons of Callithrix jacchus were examined to identify spondy-loarthropathy. Erosive disease in Callithrix was confirmed as spondy-loarthropathy on the basis of diagnostic sacroiliac erosions, syndesmophyte formation, and the nature and…
Several types of pathological bony overgrowth are known from various dinosaur taxa but, except for stress fractures, are rarely reported from appendicular elements. Herein we describe pathological manual and pedal phalanges of a camarasaurid sauropod…
Two unusual bumps occur on the internal surface of a rib of the marine reptile Prognathodon saturator from the Upper Cretaceous (Maastrichtian) of Maastricht, The Netherlands. These bumps are interpreted as stress fractures, possibly related to…
Assigning responsibility for the origins of treponemal disease has been complicated because of the (diagnostic) impreciseness of the historical written record and the inability to microbiologically distinguish among the treponematoses. Bedouin…
Examination of preserved skin from a duckbill dinosaur revealed disruption of the normal scale pattern and replacement by granulation tissue. Wrinkles radiating outward from the scar document wound contraction similar to that seen in modern injuries.…
Objectives: This study was performed to complement studies on spondyloarthropathy in rhesus macaques by quantifying and characterizing another major form of arthritis and contrasting it with osteoarthritis. Methods: Skeletons of 269 macaques of known…
Shark bite marks on mosasaur bones abound in the fossil record. Here we review examples from Kansas (USA) and the Maastrichtian type area (SE Netherlands, NE Belgium), and discuss whether they represent scavenging and/or predation. Some bite marks…
