The palaeopathology of industry, a perspective from Britain.

OBJECTIVES: This article considers the position of palaeopathology of ca. 1750AD onward within the subdiscipline of Industrial Archaeology, and reflects upon the relationship between skeletal palaeopathology and textual sources on disease prevalences. METHODS: It draws upon the author's experience in engaging with threat-led archaeology. It synthesises key elements of palaeopathological literature, emphasising contributions to the IJPP VSI 'Changes in Health with the Rise of Industry', and also the broader literature regarding Industrial Archaeology. RESULTS: Industrial Archaeology has seen a recent refocus to include not only a concentration upon technological aspects of industry but also increased emphasis the social context of industrialisation. This movement toward a placement of people as well as machines centre stage has resulted in an environment conducive for paleopathology to make a greater impact upon studies of the period. CONCLUSIONS: Palaeopathologists need to ensure that their biocultural work is orientated toward research goals of broader relevance if the impact of their work is to be maximised. We cannot directly align prevalence data generated from skeletal and and written sources; roles played by these two sources of evidence will depend, inter alia, upon the problems being investigated. SIGNIFICANCE: The success of 'Industrial Palaeopathology' will be measured by the extent to which human remains studies move toward centre stage within the broader discipline of Industrial Archaeology. LIMITATIONS: Multiple perspectives on disciplinary development are possible. Academic traditions, relationships between university- and threat led-sectors, and the opportunities and challenges engendered by working with human remains, differ in different countries.

A content analysis by bibliometry of the first ten years of the International Journal of Paleopathology.

OBJECTIVES: The aim is to provide an overview of the nature of the content of palaeopathology articles in the International Journal of Paleopathology during the first ten years of publication (2011-2020), and to compare these results with those from other similar journals. METHODS: The method used is bibliometry of International Journal of Paleopathology plus nine other periodicals publishing in the field of osteoarchaeology / palaeopathology. In these ten journals, 2513 publications in human osteology are reviewed of which 1032 are devoted specifically or substantially to palaeopathology. RESULTS: International Journal of Paleopathology has attracted a large number of palaeopathology publications, but this has not been at the expense of extant journals. Its appearance appears to have coincided with an expansion of the discipline, and it may also act as a focus for publication for articles that would not previously have found a venue. Its output is distinctive from other journals assessed, with greater emphasis on review articles (including those focusing on method and theory in palaeopathology) and, especially, on case reports. SIGNIFICANCE: International Journal of Paleopathology acts as a focal point for publications from diverse areas of the field. The connection with the Paleopathology Association provides a conduit by which outcomes of debates within the profession concerning future priorities for the field (e.g. development of method and theory; the status of the case report within the discipline) can be reflected in journal policy. LIMITATIONS: Palaeopathology and other osteoarchaeology articles are published in venues other than those analysed in the current work.

A dual process model for paleopathological diagnosis.

OBJECTIVES: This paper aims to provide an explicit theoretical model for the cognitive processes involved in paleopathological diagnosis. METHODS: The approach adopted is a dual process model (DPM). DPMs recognize that cognition is a result of both Type 1 (intuitive) and Type 2 (analytical) processes. DPMs have been influential for understanding decision-making in a range of fields, including diagnosis in clinical medicine. Analogies are drawn between diagnosis in a clinical and a paleopathological setting. RESULTS: In clinical medicine, both Type 1 and Type 2 processes play a part in diagnosis. In paleopathology the role of Type 1 processes has been unacknowledged. However, like clinical diagnosis, paleopathological diagnosis is inherently a result of a combination of both Type 1 and Type 2 processes. A model is presented by which Type 1 processes can be explicitly incorporated into a scientific approach to diagnosis from skeletal remains, and in which diagnosis is formalized as a process of hypothesis testing. SIGNIFICANCE: Accurately modelling our diagnostic processes allows us to understand the biases and limitations in our work and potentially helps us to improve our procedures, including how we impart diagnostic skills in pedagogical settings. LIMITATIONS: This work provides a theoretical model for paleopathological diagnosis. However, such models are by their nature dynamic and developing rather than static entities; it is hoped that this work stimulates further debate and discussion in this important area.

Age-related cortical bone loss in women from a 3rd-4th century AD population from England.

Age-dependent cortical bone loss in adult females from a skeletal assemblage from 3rd-4th century AD England was studied using metacarpal radiogrammetry. Results showed reduced peak cortical bone thickness compared with modern subjects, and the magnitude of cortical bone loss in older females compared with their younger counterparts was greater than that documented for a modern reference population. An elevated prevalence of fractures classically associated with osteoporosis was also observed in the over-50-year cohort. The severity of osteoporosis in this group is difficult to explain in terms of extraneous factors relating to 3rd-4th century lifestyles. Given the important genetic component in osteoporosis, the results may indicate some inherent susceptibility in this particular population to the disease, and ways in which this possibility might be further explored are suggested.

Paleopathological study of hallux valgus.

Hallux valgus is the abnormal lateral deviation of the great toe. The principal cause is biomechanical, specifically the habitual use of footwear which constricts the toes. In this study, descriptions of the anatomical changes of hallux valgus from published cadaveric and clinical studies were used to generate criteria for identifying the condition in ancient skeletal remains. The value of systematic scoring of hallux valgus in paleopathology is illustrated using two British skeletal series, one dating from the earlier and one from the later Medieval period. It was found that hallux valgus was restricted to later Medieval burials. This appears consistent with archaeological and historical evidence for a rise in popularity, during the late Medieval period (at least among the richer social classes), of narrow, pointed shoes which would have constricted the toes.

Osteoporosis in earlier human populations.

Skeletons excavated from archeological sites form a rich resource for research into ancient disease. This article takes the form of a brief review of some of the work that has been conducted on osteoporosis in past populations using collections of ancient skeletons. It is clear from this work that osteoporosis has a long history in humankind.
