Advancing the understanding of treponemal disease in the past and present.

Syphilis was perceived to be a new disease in Europe in the late 15th century, igniting a debate about its origin that continues today in anthropological, historical, and medical circles. We move beyond this age-old debate using an interdisciplinary approach that tackles broader questions to advance the understanding of treponemal infection (syphilis, yaws, bejel, and pinta). How did the causative organism(s) and humans co-evolve? How did the related diseases caused by Treponema pallidum emerge in different parts of the world and affect people across both time and space? How are T. pallidum subspecies related to the treponeme causing pinta? The current state of scholarship in specific areas is reviewed with recommendations made to stimulate future work. Understanding treponemal biology, genetic relationships, epidemiology, and clinical manifestations is crucial for vaccine development today and for investigating the distribution of infection in both modern and past populations. Paleopathologists must improve diagnostic criteria and use a standard approach for recording skeletal lesions on archaeological human remains. Adequate contextualization of cultural and environmental conditions is necessary, including site dating and justification for any corrections made for marine or freshwater reservoir effects. Biogeochemical analyses may assess aquatic contributions to diet, physiological changes arising from treponemal disease and its treatments (e.g., mercury), or residential mobility of those affected. Shifting the focus from point of origin to investigating who is affected (e.g., by age/sex or socioeconomic status) and disease distribution (e.g., coastal/ inland, rural/urban) will advance our understanding of the treponemal disease and its impact on people through time.

Changes in health with the rise of industry.

Since the publication of the Christ Church Spitalfields crypt, London, in 1993, archaeologists and paleopathologists have increasingly recognized the importance of post-medieval burial assemblages. Increasingly paleopathologists have explored the impact industrialization and urbanization had on disease. This virtual special issue focuses upon a global examination of the transition to industry commencing in the mid-18th century. The objectives are to identify commonalities and disparities in general health during the development of industry within a global context, and to examine, and in some cases challenge, long-held assumptions about health during this period of dramatic social change. It gathers together papers from international scholars in order to examine patterns in health experience throughout the transition to industry. The individual papers address this transition in terms of the unique chronological, political, economic, and social parameters of their specific region. This introduction identifies long held assumptions about the impact the industrial revolution had on health and outlines the specific environmental and social conditions of industry that influenced human disease.

The dark satanic mills: Evaluating patterns of health in England during the industrial revolution.

OBJECTIVE: this research seeks to investigate the impact the industrial revolution had on the population of England. MATERIALS: Pre-existing skeletal data from 1154 pre-Industrial (1066-1700 CE) and 4157 industrial (1700-1905) skeletons from 21 cemeteries (N = 5411). METHODS: Context number, sex, age-at-death, stature and presence/absence of selected pathological conditions were collated. The data were compared using chi square, Kolmogorov-Smirnov, t-tests and logistic regression (α = 0.01). RESULTS: There was a statistically significant increase in cribra orbitalia, periosteal reactions, rib lesions, fractures, rickets, osteoporosis, osteoarthritis, enamel hypoplasia, dental caries and periapical lesions in the industrial period. Osteomyelitis decreased from the pre-industrial to industrial period. CONCLUSION: Our results confirm the industrial revolution had a significant negative impact on human health, however the prevalence of TB, treponemal disease, maxillary sinusitis, osteomalacia, scurvy, gout and DISH did not change, suggesting these diseases were not impacted by the change in environmental conditions. SIGNIFICANCE: This is the largest study of health in the industrial revolution that includes non-adults and adults and considers age-at-death alongside disease status to date. This data supports the hypothesis that the rise of industry was associated with a significant decline in general health, but not an increase in all pathological conditions.

Two probable cases of treponemal disease of Medieval date from England.

Two British Medieval skeletons are described. Paleopathological examination suggests that treponemal disease was present in each case. Radiocarbon dating indicates that one is firmly pre-Columbian, and the other of likely pre-Columbian date. The implications for our understanding of the history and geographic spread of the treponemal diseases, particularly venereal syphilis, are discussed.
