Leprosy: The age-old companion of humans - Re-evaluation and comparative analysis of Avar-period cases with Hansen's disease from the Danube-Tisza Interfluve, Hungary.

In recent years, our knowledge of leprosy in the past has substantially been enriched. Nonetheless, much still remains to be discovered, especially in regions and periods from where no written sources are available. To fill in some research gaps, we provide the comparative analysis of eight Avar-period leprosy cases from the Danube-Tisza Interfluve (Hungary). In every case, to reconstruct the biological consequences of leprosy, the detected bony changes were linked with palaeopathological and modern medical information. To reconstruct the social consequences of being affected by leprosy, conceptualisation of the examined individuals' treatment in death was conducted. In every case, the disease resulted in deformation and disfigurement of the involved anatomical areas (rhinomaxillary region, feet, and/or hands) with difficulties in conducting certain physical activities. These would have been disadvantageous for the examined individuals and limited or changed their possibilities to participate in social situations. The most severe cases would have required continuous support from others to survive. Our findings indicate that, despite their very visible disease and associated debility, the examined communities did not segregate leprosy sufferers but provided and cared for them, and maintained a strong enough social network that made their survival possible even after becoming incapable of self-sufficiency.

Lumbosacral tuberculosis, a rare manifestation of Pott's disease - How identified human skeletons from the pre-antibiotic era can be used as reference cases to establish a palaeopathological diagnosis of tuberculosis.

The macromorphological examination of identified human osteological collections from the pre-antibiotic era (e.g., Terry Collection) can provide invaluable information about the skeletal manifestations of tuberculosis (TB) in individuals who did not receive pharmaceutical therapy. With analysis of such collections, new diagnostic criteria for TB can be recognised which can be used in palaeopathological interpretation. The aim of our paper is to provide a reference and aid for the identification of TB in past populations by demonstrating and discussing in detail the vertebral alterations indicative of one of its rare skeletal manifestations, lumbosacral TB. These changes were detected in two individuals from the Terry Collection (Terry No. 760 and Terry No. 1093). These two case studies furnish palaeopathologists with a stronger basis for diagnosing lumbosacral TB in skeletons which exhibit similar vertebral lesions from osteoarchaeological series. To illustrate this, an archaeological case from Hungary (KK146) is also presented, displaying vertebral alterations resembling that of the two cases from the Terry Collection. Through the demonstrated case studies, we can derive a better insight into the disease experience of people who lived in the past and suffered from TB.
