Craniometric Analysis of Thalassemic Individuals From Neolithic Northern Vietnam (4000–3500 bp )
Thalassemia is an inherited blood disorder affecting hemoglobin synthesis that is common in the Mediterranean, Middle East, Indian subcontinent, and Southeast Asia. Skeletal evidence for the disease has been identified in Mainland Southeast Asia as early as 7000 years ago. Thalassemia results in hyperactive marrow expansion, increasing the brittleness of bone and leading to poorer preservation in the archaeological record. Thus, the disease is li…
Skeletal Dysplasia During the Bronze Age in Northeast Thailand (3000–2500 BP)
This study examines a case of skeletal dysplasia in an adult male (B290) from the Bronze Age at the site of Ban Non Wat, Northeast Thailand. Skeletal dysplasia, a group of genetic disorders affecting bone and cartilage growth, presents diagnostic challenges due to overlapping clinical features. B290 exhibited rhizomelia, humeral varus deformity, coxa vara, and block thoracic vertebra. A thorough differential diagnosis comparing 56 skeletal dyspla…
Nutritional Deficiency Contributing to Physical Impairment of an Individual in the Metal Period Philippines (~2000–1800 bp )
Scurvy is being increasingly identified in deep antiquity in the tropics of the Asia‐Pacific region. We report a case of scurvy in a young adult male from Metal Period (~2000–1800 bp ) northern Philippines who lived with previously identified at least partial immobility due to left hip ankylosis that likely formed in adulthood. Our follow up paleopathological examination of the complete skeleton identified symmetrical and discrete new bone and/or…
Dental Stigmata and Skeletal Lesions of Congenital Treponematosis in Early Agricultural Vietnam (4000–3500 bp )
Prior research has documented treponematosis at a single site in Mainland Southeast Asia from northern Vietnam dated to the early agricultural transition (~4000–3500 bp ). To date, no other cases in Southeast Asia's prehistory have been identified. Here, we present evidence for congenital treponematosis in three non‐adults from two different sites in north and south Neolithic Vietnam (4000–3200 bp ) who present with dental and/or skeletal evidenc…
Hypomineralization disorder in tropical Southeast Asia during the agricultural revolution
This paper presents evidence for hypomineralization disorders (rickets and osteomalacia) in non-adults at Man Bac, a Neolithic site from northern Vietnam dated to 4000-3500BP, contributing to the well-described disease burden at the site that includes scurvy, treponemal disease, thalassemia, and malaria. Forty-four non-adults (<20 years of age-at-death) were assessed for macroscopic and radiographic evidence for hypomineralization disorders. Diff…
Nutritional deficiency and ecological stress in the Middle to Final western Jōmon
Despite significant research, the direct and indirect causes of a population decline in the eponymous foragers of the Late Jōmon period (c. 4500-2300 BP) in Japan remains undetermined. Here, the authors examine the impact of nutritional stress, using scurvy as a case study, on Middle and a Late/Final Jōmon populations. While an increase in the prevalence of scurvy between the time periods is apparent, no associated change in age at death was obse…
The role of dietary calcium in the etiology of childhood rickets in the past and the present
For more than two centuries, lack of sunlight has been understood to cause vitamin D deficiency and documented as a primary cause of rickets. As such, evidence of rickets in the archeological record has been used as a proxy for vitamin D status in past individuals and populations. In the last decade, a clinical global consensus has emerged wherein it is recognized that dietary calcium deficiency also plays a role in the manifestation of rickets a…

Pott’s Disease in a Liao Dynasty (Tenth to Twelfth Century A.D.) Adult from Mongolia
We describe a case of Pott’s disease from the Liao Dynasty of the Khitan Empire (947–1125 A.D.) in Mongolia.A young adult male (AT-840) from the site of Ulaan Kherem, a fortified settlement in Central Mongolia, was assessed for evidence of skeletal pathology. Radiographs were taken of lytic lesions of the thorax to assist with diagnosing the etiology. A differential diagnosis was completed using standard and new threshold criteria. AT-840 present…
Paleoepidemiological Considerations of Mobility and Population Interaction in the Spread of Infectious Diseases in the Prehistoric Past
The processes of human mobility have been well demonstrated to influence the spread of infectious disease globally in the present and the past. However, to date, paleoepidemiological research has focused more on factors of residential mobility and population density as drivers for epidemiological shifts in prehistoric infectious disease patterns. A strong body of epidemiological literature exists for the dynamics of infectious disease spread thro…

Thalassemia major in a 49-year-old Thai female
ObjectiveWe present a clinically diagnosed case of beta thalassemia major in a deceased 49-year-old Thai female for comparison with paleopathological cases and consideration of age-related changes of anemic skeletal lesions.MethodsDry bone and radiographic descriptions of pathological changes are provided and compared to clinically documented features of thalassemia.ResultsThe limb bones in this case exhibit extreme "ballooning" (widening), corti…
Two Probable Cases of Infection with Treponema pallidum during the Neolithic Period in Northern Vietnam (ca. 2000–1500 B.C.)
Skeletal evidence of two probable cases of treponematosis, caused by infection with the bacterium Treponema pallidum, from the northern Vietnamese early Neolithic site of Man Bac (1906–1523 cal B.C.) is described. The presence of nodes of subperiosteal new bone directly associated with superficial focal cavitations in a young adult male and a seven-year- old child are strongly diagnostic for treponemal disease. Climatic and epidemiological contex…

A New Application of the Bioarchaeology of Care Approach
A case of disability in the Metal Period of the Philippines, likely requiring healthcare from others, is presented to explore aspects of group dynamics in this period of antiquity. B243, a middle-aged man excavated from the Napa site in the central Philippines, suffered severe trauma to the right leg resulting in considerable restrictions to mobility and self-maintenance of survival-related behaviours such as food provision and hygiene. It is lik…
