Clinical and Anthropological Analyses of a Case From 19th Century South Africa With a Confluence of Uncommon Cranial Pathological Conditions.

This study combines clinical and anthropological analyses to investigate the complex cranial pathology of a South African individual from the 19th century. The cranium was examined macroscopically and radiographically. Conducting a standard differential diagnosis was challenging given the complexity and uncommon nature of the pathology and required drawing on relatively sparse paleopathological and clinical case reports. Multiple conditions were identified including biparietal thinning, basilar invagination, platybasia, and complicated chronic frontal sinusitis, where the intracranial extension of sinus infection may likely have contributed to the individual's death. The authors urge for awareness of these uncommon conditions, as their presence can easily be overlooked or confound skeletal assessments. This clinical study contributes to the authors' understanding of uncommon and poorly described paleopathological diseases and will help to better facilitate their diagnosis in future research. It represents one of the first studies describing such an unusual cooccurrence of uncommon pathologies in an archeological individual.

A macroscopic assessment of porosity and new bone formation on the inferior pars basilaris: Normal growth or an indicator of scurvy?

OBJECTIVES: This research aims to determine the aetiology of porosity and subperiosteal new bone formation on the inferior surface of the pars basilaris. MATERIALS: A total of 199 non-adult individuals aged 36 weeks gestation to 3.5 years, from a total of 12 archaeological sites throughout the UK, including Iron Age (n=43), Roman (n=12), and post-medieval (n=145) sites, with a preserved pars basilaris. METHODS: The pars basilaris was divided into six segments, with porosity (micro and macro) and subperiosteal new bone formation recorded on the inferior surface in scorbutic and non-scorbutic individuals. Scurvy was diagnosed using criteria from the palaeopathological literature that was developed using a biological approach. RESULTS: There was no statistically significant difference in microporosity between scorbutic and non-scorbutic individuals in four out of the six segments analysed. There was a significant negative correlation between age and microporosity in non-scorbutic and scorbutic individuals. A significant difference in subperiosteal new bone formation was observed between scorbutic and non-scorbutic individuals. CONCLUSIONS: Microporosity on the inferior pars basilaris should not be considered among the suite of lesions included in the macroscopic assessment of scurvy in non-adult skeletal remains (less than 3.5 years). SIGNIFICANCE: This study highlights the risk of over diagnosing scurvy in past populations. LIMITATIONS: It is difficult to distinguish between physiological (normal) and pathological (abnormal) bone changes in the skeleton of individuals less than one year of age. SUGGESTIONS FOR FURTHER RESEARCH: Future research should focus on the analysis of individuals over 3.5 years of age.

A historical and palaeopathological perspective on cancer.

Cancer is often wrongly considered to be a modern disease in many popular medical venues. Cancers have been known to humanity since ancient times. In fact, its antiquity can be identified through the application of palaeopathological methodologies. The present perspective demonstrates by means of a historical and palaeopathological analysis how oncological manifestations were present long before the emergence of anatomically modern humans and addresses the epidemiological transition from ancient times to the contemporary world. The final section of the article examines breast cancer and its identification in ancient human remains.

Diets, stress, and disease in the Etruscan society: Isotope analysis and infantile skeletal palaeopathology from Pontecagnano (Campania, southern Italy, 730-580 BCE).

Susceptibility to morbidity and mortality is increased in early life, yet proactive measures, such as breastfeeding and weaning practices, can be taken through specific investments from parents and wider society. The extent to which such biosocialcultural investment was achieved within 1st millennium BCE Etruscan society, of whom little written sources are available, is unkown. This research investigates life histories in non-adults and adults from Pontecagnano (southern Italy, 730-580 BCE) in order to track cross-sectional and longitudinal breastfeeding and weaning patterns and to characterize the diet more broadly. Stable carbon and nitrogen isotope analysis of incrementally-sampled deciduous and permanent dentine (n = 15), bulk bone collagen (n = 38), and tooth enamel bioapatite (n = 21) reveal the diet was largely based on C3 staple crops with marginal contributions of animal protein. Millet was found to play a role for maternal diet and trajectories of breastfeeding and feeding for some infants and children at the site. The combination of multiple isotope systems and tissues demonstrates exclusive breastfeeding was pursued until 0.6 years, followed by progressive introduction of proteanocius supplementary foods during weaning that lasted between approximately 0.7 and 2.6 years. The combination of biochemical data with macroscopic skeletal lesions of infantile metabolic diseases and physiological stress markers showed high δ15Ndentine in the months prior to death consistent with the isotopic pattern of opposing covariance.

Chronic Maxillary Sinusitis: A comparison of osteological and CT methods of diagnosis.

OBJECTIVE: To assess the differences between endoscopic and radiological methods of analysis for diagnosing chronic maxillary sinusitis (CMS) in archaeological skeletal remains. MATERIALS: 32 crania from a Dutch post-medieval rural population. METHODS: We assessed the presence of bone changes indicative of CMS (i.e., bone growth and bone resorption) both endoscopically and through computed tomography (CT), and then compared results. RESULTS: We observed moderate agreement between bone growth scores obtained through endoscopy and CT, and fair agreement when assessing bone resorption. CONCLUSIONS: CMS prevalence rates observed through CT may be comparable to rates assessed endoscopically, although caution is needed when making direct comparisons. SIGNIFICANCE: This is the first study comparing data obtained through endoscopy and radiological methods in the study of CMS, informing paleopathologists about potential biases in data comparison. LIMITATIONS: Our small sample size likely impacted results. SUGGESTIONS FOR FURTHER RESEARCH: Further research is advised to fully explore the comparability of endoscopic and radiological method of analysis in the study of sinusitis. DATA AVAILABILITY: The datasets generated and analyzed during the current study are available upon request.

Two cases of smallpox from 1540 CE circum-contact (early colonial) Northern Coastal Peru.

OBJECTIVE: This project seeks to create a differential diagnosis for lesions found on the skeletal remains of two children as a means to explore the presence of viral disease in 16th- century Peru. MATERIALS: Extremely well-preserved human remains of two children who died between the ages of 1-2 years old, recovered from the circum-contact (∼1540 CE) cemetery in Huanchaco, Peru. METHODS: Macroscopic and radiographic analysis. RESULTS: Both individuals present with cortical thickening, symmetrical destructive lesions, metaphyseal expansion, perforations, exposure of the medullary cavity, resorption of metaphyseal ends and necrosis of the long bones, and deposited reactive new bone. These features are consistent with osteomyelitis variolosa and bacterial osteomyelitis. CONCLUSIONS: Three features of Individuals IG-124 and IG-493 suggest a highly consistent diagnosis of osteomyelitis variolosa: multiple skeletal lesions, the historical context of the area, and the high mortality rate of non-adults in the circum-contact cemetery. SIGNIFICANCE: Although viral infections are ubiquitous and well documented historically, their etiologies are often difficult to determine in archaeological populations. Orthopoxvirus variola (smallpox) is one of the many viruses whose archaeological impact is still under explored in skeletal remains. LIMITATIONS: The absence of smallpox in other children from the Huanchaco cemetery creates difficulty in ascertaining true prevalence rates or information on potential outbreaks. SUGGESTIONS FOR FURTHER RESEARCH: Further research analyzing aDNA from calculus and/or residues using a DIP-GC-MS method might create a better understanding of how smallpox spread through the region.

Protozoan parasites of birds from the Tremembé formation (Oligocene of the Taubaté Basin), São Paulo, Brazil.

OBJECTIVE: To analyze the presence of protozoan parasites in bird coprolites from the Tremembé Formation (Oligocene of the Taubaté Basin). MATERIALS: Twenty avian coprolites embedded in pyrobituminous shale matrices. METHODS: Samples were rehydrated and subjected to spontaneous sedimentation. RESULTS: Paleoparasitological analyses revealed oocysts compatible with the Eimeriidae family (Apicomplexa) and one single Archamoebae (Amoebozoa) cyst. CONCLUSIONS: The present work increases the amount of information about the spread of infections throughout the Cenozoic Era and reveals that the Brazilian paleoavifauna played an important role in the Apicomplexa and Amoebozoa life cycles. SIGNIFICANCE: This is the first record of protozoans in avian coprolites from the Oligocene of Brazil. These findings can help in the interpretation of phylogenies of coccidian parasites of modern birds, as certain taxonomic characters observed in the Oligocene Protozoa characterize monophyletic groups in current molecular phylogenetic analyses. LIMITATIONS: None of the oocysts were sporulated; therefore, it is not possible to identify the morphotypes to genus or species. SUGGESTIONS FOR FURTHER RESEARCH: Our results create new perspectives related to biogeographic studies of the parasitic groups described and may improve the understanding of the temporal amplitude of parasitic evolutionary relationships between Protozoans and birds.

Fate and preservation of the late pleistocene cave bears from Niedzwiedzia Cave in Poland, through taphonomy, pathology, and geochemistry.

This comprehensive study examines fossil remains from Niedzwiedzia Cave in the Eastern Sudetes, offering detailed insights into the palaeobiology and adversities encountered by the Pleistocene cave bear Ursus spelaeus ingressus. Emphasising habitual cave use for hibernation and a primarily herbivorous diet, the findings attribute mortality to resource scarcity during hibernation and habitat fragmentation amid climate shifts. Taphonomic analysis indicates that the cave was extensively used by successive generations of bears, virtually unexposed to the impact of predators. The study also reveals that alkaline conditions developed in the cave during the post-depositional taphonomic processes. Mortality patterns, notably among juveniles, imply dwindling resources, indicative of environmental instability. Skeletal examination reveals a high incidence of forelimb fractures, indicating risks during activities like digging or confrontations. Palaeopathological evidence unveils vulnerabilities to tuberculosis, abscesses, rickets, and injuries, elucidating mobility challenges. The cave's silts exhibit a high zinc concentration, potentially derived from successive bear generations consuming zinc-rich plants. This study illuminates the lives of late cave bears, elucidating unique environmental hurdles faced near their species' end.

Periodontitis and alveolar resorption in human skeletal remains: The relationship between quantitative alveolar bone loss, occlusal wear, antemortem tooth loss, dental calculus and age at death in a low socioeconomic status, modern forensic human collection from Yucatan.

OBJECTIVE: This paper assesses the relationship between the distance between the cemento-enamel junction and alveolar crest and risk factors commonly associated with periodontitis. MATERIALS: Eighty individuals between 28 and 92 years old with known biological sex and age were analyzed from a 20th century forensic human collection from Merida, Yucatan (Mexico). METHODS: Macroscopic assessment, along with metric analysis, was employed using a probe. RESULTS: Ante-mortem tooth loss was positively correlated with the distance between the cemento-enamel junction and alveolar crest, as was the presence of root calculus in females. CONCLUSIONS: Cemento-enamel junction to alveolar crest distance is not a reliable indicator of periodontitis since it is not directly related to periodontitis-causing infectious pathogens, and since ante-mortem tooth loss can affect root exposure. SIGNIFICANCE: This study demonstrates that a purely quantitative approach to diagnosing periodontitis in archaeological and forensic human remains can be misleading. LIMITATIONS: The skeletal collection is only representative of the low socioeconomic class of Merida, and its female cohort is underrepresented. In addition, because the Xoclan collection is modern, limitations (particularly with respect to tooth wear) of the applicability of these interpretations to older archaeological remains exist. SUGGESTION FOR FURTHER RESEARCH: A combination of quantitative and qualitative characteristics of alveolar bone is needed to reliably diagnose periodontitis in skeletal populations.

Evidence of non-adult vitamin C deficiency in three early medieval sites in the Jaun/Podjuna Valley, Carinthia, Austria.

OBJECTIVE: This study aims to determine and discuss the prevalence of non-adult scurvy cases from the early medieval Jaun/Podjuna Valley in southern Austria. MATERIALS: 86 non-adult individuals were assessed from three early medieval sites. METHODS: Morphological characteristics associated with suggestive and probable scurvy were observed macroscopically and under 20-40x magnification. RESULTS: A significant relationship between the prevalence of scurvy and age group was observed. Perinates (46%, 6/13) and children (27.5%, 8/28) showed a high prevalence of skeletal features indicating a diagnosis of scurvy, while no cases of scurvy were observed in adolescents and adults. CONCLUSIONS: In this Alpine region, scurvy occurred frequently in infants and children. Seasonal fluctuations of diet are discussed as factors triggering scurvy. SIGNIFICANCE: This study sheds new light on the prevalence of scurvy in the Alpine region and how the region developed after the fall of the Roman Noricum. It also models ways in which multiple lines of evidence can contribute to the diagnostic process. LIMITATIONS: Poor preservation posed a challenge to identifying probable cases of scurvy. Likewise, non-adult remains are difficult to diagnose due to their developing nature and it is not always possible to distinguish between normal bone growth and pathological growth. SUGGESTIONS FOR FURTHER RESEARCH: Future applications of biomolecular studies will help illustrate changes in diet that may have contributed to vitamin deficiencies.

Calcified uterine leiomyoma from an 18th-century nunnery in North Italy.

OBJECTIVE: To develop a differential diagnosis of a mass retrieved alongside skeletal remains in the crypt of the church of Santissima Annunziata of Valenza (Province of Alessandria, Northern Italy). MATERIAL: A calcified mass measuring 40 × 39 mm and 17.62 × 16.3817.62 × 16.38 mm. METHOD: The analysis utilized macroscopic assessment and histologic examination (including histochemical and immunohistochemical analyses). RESULTS: Morphological traits include an irregular and spongy external surface. Holes of different sizes lead toward the inner part of the object. A section of the mass shows an "intertwined bundle" pattern, confirmed by microscopic examination. CONCLUSIONS: Differential diagnosis determined the mass to be consistent with calcified leiomyoma. SIGNIFICANCE: Identifying uterine leiomyoma adds to the paucity of paleopathological literature on the condition and to calcified tumors more broadly. It also allows for an important discussion of women's gynecological health in the past and potentially among nulliparous women. LIMITATIONS: Neither histochemical staining nor immunohistochemical analysis demonstrated the certain muscular nature of the specimens due to the rehydration and decalcification processes, for which there are no gold standards. SUGGESTIONS FOR FURTHER RESEARCH: Calcified masses are common in the clinical literature but remain rare in paleopathological literature. Careful excavation and improved recognition of apparently calcified masses are necessary to improve recognition, diagnosis, and interpretation.

Perspectives on anemia: Factors confounding understanding of past occurrence.

OBJECTIVE: This paper reviews factors confounding the understanding of the past occurrence of anemia. Using the evidence gathered, a framework is presented of ways forward to enable greater confidence in diagnosing acquired anemia in paleopathology, facilitating insights into longer-term perspectives on this globally relevant condition. RESULTS: To date, porotic lesions have been central to paleopathological investigations of anemia. The fact that porotic bone lesions are omnipresent and have multiple causes but are likely to have a relatively low, age-related frequency in individuals with anemia, a condition that will have been common in past communities, is confounding. METHODS: Establishing frameworks that move away from porotic lesions is proposed to facilitate higher levels of more accurate anemia diagnoses in paleopathology. SIGNIFICANCE: Acceptance of the fundamental principle that anemia may be better considered as a condition requiring metric evaluation of bone structures, supplemented by careful consideration of lesions, will advance understanding of acquired anemia in past communities. Such an approach would provide a clear basis for further consideration of congenital conditions causing anemia, such as sickle-cell disease and thalassemia. LIMITATIONS: This paper simply opens the conversation on the better diagnosis of anemia in paleopathology; it starts the iterative process of achieving some consensus and progress on diagnosing anemia in paleopathology. SUGGESTIONS FOR FURTHER RESEARCH: Engagement with ideas presented, sharing data and development of metric parameters will assist in identifying the effects of marrow hyperplasia on bone, enabling more robust work on the important topic of anemia.

Porotic hyperostosis and cribra orbitalia in samples from the Late Hillfort Period sites at Detkovice - Za zahradama (district Prostejov) and Vídenská street (district Brno), Czech Republic.

Porotic hyperostosis and cribra orbitalia are pathological changes occurring on the human skull. These changes were observed and evaluated on skeletal remains from Detkovice - Za zahradama and Vídenská Street in Brno; both sites are dated back to the 10th to 12th centuries AD. A total of 605 subjects were assessed for age, sex, and the above-stated pathologies using standard methods. The influence of age and sex on the occurrence of these pathologies was examined statistically. Results indicated that at the site of Detkovice - Za zahradama, porotic hyperostosis, and cribra orbitalia do not depend on sex or age. However, at Vídenská Street in Brno, these pathologies do not depend on sex, but they depend on age so a higher incidence of pathologies in juveniles is observed. Differences between both sites could be caused by different numbers of evaluated individuals or different state of preservation of skeletal remains. The aetiology of the origin of these pathologies could not be determined by the methodology used here, but with the prevailing lower age of pathological subjects, a lack of nutrition with consequent absence of iron and developing anaemia might be the cause. Based on our statistical data, we can observe that the pathologies we studied occur more frequently in children older than newborns and younger infants. This may indicate that these studied pathologies arise only during the lifetime of the individual and do not have a prenatal occurrence.

Is the promontory a promising site to diagnose otitis media in paleopathology? A search for evidence.

OBJECTIVE: The promontory of the middle ear was recently suggested to be an appropriate site for diagnosing otitis media (OM) in archaeological bones by endoscopic inspection. The present study scrutinized the underlying assumption that a bulgy, irregular promontorial surface represents a pathological condition. MATERIALS: We compared an allegedly healthy individual and an allegedly diseased individual in skeletal remains of two human individuals from the early Medieval period in Germany. METHODS: The specimens were studied using microscopic analyses of thin ground sections. RESULTS: The osseous architecture of the three-layered promontorial wall was the same in both specimens. Both the contour of the resorption front of the middle layer and the thickness of the overlying outer periosteal layer showed some variation, resulting in an either smooth or a bulgy promontorial surface, while signs of resorptive or proliferative changes at the periosteal surface were missing in both cases. CONCLUSIONS: Our results suggest that an irregular promontorial surface represents normal variation in the development of the otic capsule rather than a pathological condition. We therefore conclude that the promontory is not an appropriate site for diagnosing OM in archaeological bone. SIGNIFICANCE: The study contributes to evidence-based diagnoses in paleo-otological studies. Our assumption is in line with clinical and experimental findings indicating that the otic capsule is protected against bone remodeling. LIMITATIONS: Only two specimens were studied. SUGGESTIONS FOR FURTHER RESEARCH: SEM-studies to detect more subtle changes to the promontorial surface.

The paleopathology and paleoepidemiology of Upper paleolithic tuberculosis: Review of evidence and hypotheses.

Molecular phylogeny work has shown that tuberculosis is ancient human-adapted infection predating the Neolithic period. They also show that the Upper Paleolithic is a key period of emergence of the MTB complex strains, contemporary with the exit of modern man from Africa. Despite the richness of Upper Paleolithic sites in Eurasia and the relative abundance of human remains, the only proven case of Paleolithic tuberculosis has been described so far date from the Azilian, a culture of the European Final Paleolithic, which is more recent than the ancient Neolithic sites of the Near East, area that currently hold the record for the oldest paleopathological evidence of tuberculosis. The purpose of this review is to present evidence for the existence of tuberculosis in the Paleolithic and to list hypotheses explaining the weak demonstrative contribution of paleopathology for pre-Neolithic periods.

Probable cases of tuberculosis in Early Medieval pastoralists of Eastern Europe.

Two anthropological collections of the 8-9th century AD from the forest-steppe area of the southern Eastern Europe has been the subject of analysis of the osteo-articular alterations concerning tuberculosis related lesions. According to archaeological data, the Mayaki and Dmitrievka groups are from the territory of Khazar Khaganate, which is well-known by historical data. It was a traditional population with settled pastoral farming. There were studied 292 adult human remains by macroscopic morphological and radiological methods. The completeness of the skeletons could have been better due to the intentional selection of their parts for the museum funds, so there were limitations for the differential diagnosis of TB by morphological criteria. In general, 31 individuals (20 men, 11 women) were marked as possible candidates with skeletal TB. The number of skeletons with possible specific infections from the two series is comparable, but according to sex distribution, there are some significant differences. If in the Dmitrievka group, there was approximately the same distribution of the number of cases of possible infected men and women; in the Mayaki group then there was a significant difference in the prevalence of the male sample. Various reasons can explain the observed differences. Firstly, we cannot rule out an error in the diagnosis of tuberculosis only by morphological methods since the preservation of the skeletons leaves much to be desired. Secondly, as it is known, only a few percent of tuberculosis patients show skeletal alterations, so the direct quantitative comparison cannot be adequate in paleopathological studies. The ambiguity of morphological criteria, particularly for destructive lesions of bone other than vertebrae, does not allow asserting that all identified cases result from TB. However, the results of differential diagnosis can underline that at least half of the skeletons have skeletal alterations most likely related to TB. The final analysis of the remains by aDNA methods will permit more certain confirmation of the diagnosis.

"Tuberculosis on the spot" - Discussion of a probable sternal tuberculosis from a late medieval cemetery from Hungary.

Investigations of non-adult remains are particularly suitable for finding epidemic periods in past populations. This study presents a probable unique example of osseous manifestation of tuberculosis on a child's skeletal remains from medieval Hungary. Between 2009 and 2011 the Field Service for Cultural Heritage excavated the exceptional cemetery of Perkáta - Nyúli-dulo in Hungary, with around 5000+ graves. The analysed skeleton (SNR 948) was located in the medieval (10-16th century) part of the cemetery. Besides the standard macroscopic pathological observation, we also performed radiographic analysis. The remains of the child (13-14 year-old) showed numerous skeletal lesions: the ribs have proliferative lesions (dense nodules) on the visceral surface of the shaft, lytic lesions with rounded edges occurred on the thoracic and lumbar vertebral bodies, and on the facies auricularis of the left ilium we can see pitting and new bone formation. What makes this pathological case exceptional is the significant change in the manubrium. It shows extensive osteolytic lesions, probably due to tuberculous osteomyelitis, which is a unique phenomenon in an archaeological context. This rare type of extra-spinal tuberculous osteomyelitis appears in less than 1% of cases with skeletal TB, and even less in case of children, according to modern medical literature. Although some cases of slight lesions on the manubrium have been described from an archaeological context, no such cases showing advanced lesions have been published so far. In the future, biomolecular analyses should be conducted as well, in order to confirm the presence of TB in this individual.

More than one millennium (2nd-16th century CE) of the White Plague in the Carpathian Basin - New cases, expanding knowledge.

The causative agent of tuberculosis is still a widespread pathogen, which caused the death of ca. 1.6 million people globally in 2021. The paleopathological study of human remains revealed the antiquity of the disease and its continuous presence throughout the history of humankind. The Carpathian Basin has always been a biocultural melting pot, since it has seen several migrations over the centuries, and served as a location of admixture and interaction for numerous populations of different cultures. Thus, this geographical territory is ideal for the examination of the coevolutionary processes of hosts and their pathogens. We aimed to reveal the spatial and temporal distribution of tuberculosis cases excavated inside the borders of Hungary between the 2nd and 16th centuries CE. We established a comprehensive database by collecting 114 already published cases and introducing 39 new cases. The involved cases include those that have been confirmed by different molecular methods, as well as possible infections that were identified based on the presence of macromorphological and radiological alterations. The progress of future molecular and paleopathological studies can be facilitated by our dataset, as it presents spatial and temporal information concerning the spread of the disease in the Carpathian Basin, as well as the biological profile and detailed paleopathological description of lesions illustrated by photo- and radiographs.

Re-examination of the Subalyuk Neanderthal remains uncovers signs of probable TB infection (Subalyuk Cave, Hungary).

In 1932, skeletal remains of two Neanderthal individuals, a young adult female and a 3-4-year-old child, were discovered in Subalyuk Cave in Northern Hungary [1,2]. Results of the anthropological examination were published some years after this important discovery. Methodological progress encouraged re-examination of the material during the last few years. Radiocarbon dating revealed a chronological age of 39,732-39,076 cal. BP for the adult female and 36,117-35,387 cal. BP for the child [3]. Morphological paleopathological studies of these Neanderthal remains uncovered distinct evidence of skeletal infections. Alterations of the adult individual's sacrum suggest probable early-stage sacroiliitis, while several vertebral bodies indicate superficial osseous remodelling of infectious origin. Traces of pathological lesions were observed on the endocranial surface of the child's skull, reflecting a reaction of meningeal tissues, a consequence of a probable TB-related meningeal infectious process. Results of recent paleomicrobiological examinations - lipid biomarker and aDNA studies - support the morphological diagnosis of probable TB infections [4].
