Objective

The first case of Legg-Calvé-Perthes disease (LCPD) in Greece is presented. LCPD, a rare disease, is discussed using the Digital Atlas of Ancient Rare Diseases (DAARD), which tests the benefits of the database for diagnosing and contextualizing the new case with 42 archaeological cases of LCPD recorded in the DAARD.

Materials

A 30–40-year-old, probable male individual was found at the archaeological site of Olympia, Greece, dating to 500–700 CE.

Methods

Biological sex, age-at-death and pathological changes were investigated using macroscopic and osteometric methods. The DAARD provided the typical characteristics of LCPD.

Results

Pathological changes in both hip joints without any other related changes in the skeleton corresponded to the skeletal features of LCPD. The DAARD produced 42 cases of LCPD, most of which from Europe, with a preference for male sex and unilateral involvement of the hip joint.

Conclusions

The DAARD aids in diagnosing rare diseases and interpreting new cases in the context of already known studies.

Significance

This study shows that the DAARD has the potential to help researchers move beyond the level of single case studies and create a broader picture of the history of rare diseases.

Limitations

This paper focuses on the benefits of the DAARD in relation to LCPD but not all rare diseases have been included in the database.

Suggestions for further research

More rare diseases from archaeological contexts should be added to the DAARD to create a base for the interpretation of their history and expand our understanding of rare diseases in the past.

目的：介绍希腊首例莱格-卡尔维-珀特氏病（LCPD）病例。我们利用古代罕见疾病数字图谱（DAARD）对 LCPD 这种罕见疾病进行了讨论，并通过 DAARD 中记录的 42 例 LCPD 考古病例，检验了该数据库在诊断新病例和确定病例背景方面的优势：材料：在希腊奥林匹亚考古遗址中发现了一个 30-40 岁的疑似男性个体，年代为公元 500-700 年：方法：采用宏观和骨计量学方法对生物性别、死亡年龄和病理变化进行了研究。DAARD 提供了 LCPD 的典型特征：结果：两个髋关节的病理变化与 LCPD 的骨骼特征相符，但骨骼中没有任何其他相关变化。DAARD产生了42例LCPD病例，其中大部分来自欧洲，男性居多，单侧髋关节受累：结论：DAARD 有助于诊断罕见疾病，并在已知研究的背景下解释新病例：本研究表明，DAARD 有可能帮助研究人员超越单个病例研究的水平，为罕见病的历史绘制更广阔的图景：局限性：本文重点介绍了 DAARD 在 LCPD 方面的优势，但并非所有罕见疾病都已纳入数据库：进一步研究的建议：应将更多考古学背景下的罕见疾病添加到 DAARD 中，为解释这些疾病的历史奠定基础，并扩大我们对过去罕见疾病的了解。

Objective

To provide an evidence-based resource for paleopathologists to consider multiple skeletal indicators of pathology associated with early tooth loss in children to aid in diagnosis.

Materials

Three databases (Cochrane Library, MedLine, and Scopus) were used for a review.

Methods

According to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) criteria, a systematic review guideline, 85 articles were selected.

Results

A total of 189 children had a syndrome or disease associated with early tooth loss. Our review, based on 25 diseases, lists the bone and dental lesions observable in archeological remains.

Conclusions

Based on a review of the literature, a synthesis of 25 diseases and syndromes that may be associated with premature loss of permanent or deciduous teeth in children was developed for paleopathologists. It highlights the importance of a thorough dental examination by paleopathologists to further assess past health conditions.

Significance

This paper provides an extensive resource addressing early tooth loss in childhood to assist researchers with differential diagnosis.

Limitations

The articles included in this review are case reports based on living populations.

Suggestions for further research

Further studies into diseases and their association with early tooth loss would complement this work, as would utilizing the differential diagnoses on archeological individuals to clarify its value and limitations.

Objectives

The objective of this study was to analyse an individual whose remains are characterised by early deciduous tooth loss and multi-focal lesions on the post-cranial skeleton.

Materials

Skeletal remains of an immature individual buried between 1770 and 1849 in London.

Methods

The remains were examined by visual macroscopic inspection, supplemented by radiographic examination of the mandible and maxillae. A differential diagnosis with possible conditions, frequent in this archaeological context, was conducted. A comprehensive examination of dental lesions was performed to investigate the aetiologies of deciduous tooth loss.

Results

The individual exhibited a mosaic of skeletal and dental pathological changes, including premature loss of deciduous dentition, premature eruption of permanent teeth generalised bone loss in both the mandible and maxilla; osteomyelitis of the left radius; osteolytic lesion on the body of the second lumbar vertebra, and marked expansions of the rib shafts due to sub-periosteal new bone formation.

Conclusion

A differential diagnosis considered indicates that the pathological changes of the individual were most likely associated with a comorbidity involving hypophosphatasia and tuberculosis.

Significance

We present in this study several oral signs that could alert paleopathologists and bioarcheologists to systematically consider the potential of a condition that is rarely encountered in archaeological contexts.

Limitations

Due to poor preservation, this study was confined to the analysis of a partial maxilla and mandible, a left radius shaft and the axial skeleton (rib heads and vertebrae) of the individual.

Suggestions for further research

Further radiographic, histological and genetic analyses would confirm the diagnosis.

材料1770 年至 1849 年间埋葬在伦敦的一个未成年个体的骨骼遗骸。方法对遗骸进行了肉眼宏观检查，并辅以下颌骨和上颌骨的放射检查。对在这种考古背景下经常出现的可能情况进行了鉴别诊断。对牙齿病变进行了全面检查，以研究乳牙脱落的病因。结果该个体表现出一系列骨骼和牙齿病变，包括乳牙过早脱落、恒牙过早萌出、下颌骨和上颌骨普遍骨质流失、左桡骨骨髓炎、第二腰椎体溶骨性病变以及骨膜下新骨形成导致的肋骨轴明显膨胀。结论鉴别诊断表明，该患者的病理变化很可能与低磷酸盐血症和结核病的合并症有关。意义我们在这项研究中发现了一些口腔迹象，这些迹象可以提醒古病理学家和生物考古学家系统地考虑一种在考古环境中很少遇到的疾病的可能性。

Objective

This case study evaluates a focal osteolytic lesion in the right sulcus sinus transversi of an isolated os occipitale.

Materials

The os occipitale is from a juvenile from the Cueva de Sangre at the Classic Period (250−900 CE) site of Dos Pilas, Guatemala

Methods

The lesion was examined macroscopically, microscopically, and radiographically.

Results

The oval lesion has a well-circumscribed margin, endocranial origin, and involves cortical destruction of the inner and outer tables. Subperiosteal bone reaction around the lesion is present on the ectocranial surface. Skeletal evidence of increased vascularity, diploë expansion, and perimortem fracture near the lesion are not observed.

Conclusions

The lesion appears to reflect a response to the presence of an expansile process that has caused pressure erosion. The anatomical location of the lesion and the endocranial origin suggest a probable vascular anomaly, such as a vascular malformation.

Significance

This case study represents one of the few bioarchaeological evaluations of probable vascular anomaly in a juvenile. As such, it expands our knowledge about vascular anomalies in the past and provides a comparative and core reference for guiding future paleopathological investigations on cranial osteolytic lesions.

Limitations

The skeletal assemblage is commingled and fragmentary preventing the assessment of the distribution of lesions across the skeleton.

Suggestions for future research

Further scrutiny of bioarchaeological collections is needed to better understand the distribution of vascular anomalies in the past.

材料该枕骨来自危地马拉多斯皮拉斯古典时期（公元 250-900 年）遗址的桑格雷洞穴。方法对该病变进行了宏观、显微和放射学检查。结果椭圆形病变的边缘呈环形，起源于颅内，涉及内、外台的皮质破坏。病变周围的骨膜下骨反应出现在颅外表面。病变附近没有观察到血管增多、二叶扩张和死前骨折的骨骼证据。病变的解剖位置和颅内起源表明可能存在血管异常，如血管畸形。因此，它扩展了我们对过去血管畸形的认识，并为指导今后对颅骨溶骨性病变的古病理学调查提供了比较和核心参考。

Which types of bony changes in the maxillary sinus indicate chronic sinusitis? 上颌窦中哪种类型的骨质变化表明患有慢性鼻窦炎？

Objectives

To determine which types of bone lesion (spicules, lobules, porous bone) in the maxillary sinus indicate sinusitis

Methods

Subadjacent dental disease is a cause of maxillary sinusitis; if a lesion type indicates sinusitis it should be more common above diseased posterior maxillary teeth than a lesion type that is not indicative of sinusitis. The study sample is a British Mediaeval human skeletal collection.

Results

Porous bone lesions (chiefly new bone deposits) in maxillary sinuses are associated with subadjacent dental disease; spicules/lobules of bone in the sinus are not.

Conclusions

The results support the idea that porous lesions indicate sinusitis but the spicules/lobules may not. Spicules, lobules and porous lesions within the maxillary sinus should be analysed separately in biocultural studies; it would be prudent to regard only the porous lesions as indicative of sinusitis.

Significance

Maxillary sinusitis is commonly used as a health indicator in palaeopathology, and spicular deposits are generally the most common type of alterations. By assuming that they are indicative of sinusitis we may have been greatly overestimating the prevalence of bony sinusitis in the past.

Limitations

These conclusions are provisional. Further work on larger, more diverse samples, together with more detailed anatomical studies on lesion location and structure is ongoing.

目的确定上颌窦中哪些类型的骨质病变（骨刺、骨小叶、多孔骨）预示着上颌窦炎方法上颌窦炎的病因之一是邻近牙齿疾病；如果一种病变类型预示着上颌窦炎，那么这种病变类型在患病的上颌后牙上方应该比不预示上颌窦炎的病变类型更常见。研究样本是英国中世纪的人类骨骼。结果上颌窦中的多孔骨病变（主要是新骨沉积）与下邻牙疾病有关；而窦中的骨刺/骨小叶则与之无关。在生物文化研究中，应分别分析上颌窦内的骨刺、小叶和多孔性病变；谨慎的做法是仅将多孔性病变视为上颌窦炎的标志。假定这些沉积物是鼻窦炎的标志，我们可能大大高估了过去骨性鼻窦炎的发病率。我们正在对更大规模、更多样化的样本进行进一步研究，并对病变位置和结构进行更详细的解剖学研究。

Objective

This study explores the interplay between age-at-death, sex and occupation and the presence, location and severity of Schmorl’s nodes.

Materials

Vertebral columns of 327 individuals, 180 (55.1%) males and 147 (44.9%) females, with age-at-death between 20 and 65 years old, with known occupation.

Methods

Schmorl’s nodes were recorded as present/absent and by location and severity.

Results

In this sample, 58.7% (192/327) of individuals were affected by Schmorl’s nodes, 75.6% (136/180) were males and 38.1% (56/147) were females, with statistically significant differences (p=0.000). Schmorl’s nodes were most commonly found on the T7-L2 (77.1% of all Schmorl’s nodes) vertebrae and at the center (73.4%) of the vertebral body surface. Age and occupational categories did not correlate with prevalence, quantity or severity.

Conclusions

Males appear more prone to develop Schmorl's nodes than females. In this study, the prevalence of Schmorl’s nodes does not increase with age, nor with the type of occupation held by males.

Significance

This study rejects the purported associations between prevalence of Schmorl’s nodes and age and physical stress.

Limitations

It is unknown whether individuals had the same occupation throughout their lives or for how long they performed it. Additionally, it is impossible to access when the individual developed the Schmorl’s node.

Evaluate the onset of Schmorl’s nodes in individuals under 20 and explore possible links between vertebral morphology and the occurrence of Schmorl’s nodes.

本研究探讨了死亡年龄、性别和职业与 Schmorl 结节的存在、位置和严重程度之间的相互作用。材料 327 名死亡年龄在 20 岁至 65 岁之间、已知职业的人的椎体，其中男性 180 人（55.1%），女性 147 人（44.9%）。结果在该样本中，58.7%（192/327）的人受到 Schmorl 节的影响，其中 75.6%（136/180）为男性，38.1%（56/147）为女性，差异有统计学意义（P=0.000）。Schmorl's结节最常见于T7-L2（占所有Schmorl's结节的77.1%）椎体和椎体表面中心（73.4%）。年龄和职业类别与发病率、数量或严重程度无关。在这项研究中，Schmorl's结节的患病率并不随年龄的增长而增加，也不随男性从事的职业类型而增加。对进一步研究的建议评估 20 岁以下人群中 Schmorl 节的发病情况，并探索脊椎形态与 Schmorl 节发生之间的可能联系。

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.

目的本研究旨在确定基底面下表面多孔和骨膜下新骨形成的病因。方法将基底动脉旁分为六个部分，记录坏血病和非坏血病患者基底动脉旁下表面的孔隙率（微孔和大孔）和骨膜下新骨形成情况。结果在所分析的六个切面中，有四个切面的微孔率在统计学上没有显著差异。非秃顶者和秃顶者的年龄与微孔之间存在明显的负相关。结论在对非成人骨骼遗骸（小于 3.5 年）进行坏血病宏观评估时，不应将基底动脉下旁的微孔视为一系列病变。意义本研究强调了在过去的人群中过度诊断坏血病的风险。局限性很难区分一岁以下个体骨骼中的生理性（正常）和病理性（异常）骨骼变化。

Objective

To analyze the overall frequency and inter-tooth patterns of caries in three populations from ancient cemeteries located along the western border of the Central Iranian Plateau as a means to explore whether the populations of Iran had greater access to fermentable sugars after the establishment of the great empires.

Materials

Dental collections from Kafarved-Varzaneh (Early Bronze Age, MNI=66), Estark-Joshaqan (Iron Age, MNI=57), Tappeh Poustchi (Timurid and Safavid Period, MNI=34), together with comparative data from NE Syria.

Methods

Frequencies of dental caries per tooth categories, location and size of carious lesions are analyzed using Smith’s Mean Measure of Divergence, Correspondence Analysis, χ² and Kruskal-Wallis tests.

Results

There are minimal differences in overall frequencies of carious lesions at Iranian sites, regardless of the chronology, but notable differences at Syrian sites. The inter-tooth pattern at the Iron Age cemetery in Estark appears distinctly different than the other Iranian sites and the comparative samples from Syria.

Conclusions

Divergent subsistence strategies may be linked with different inter-tooth patterns since people buried at Estark were mobile herders, while the other cemeteries were used by settled farmers.

Significance

This comprehensive research on dental caries in three chronologically diverse populations in Iran sheds light on the association between dental caries and subsistence strategies, and introduces the Smith’s Mean Measure of Divergence to explore inter-tooth carious patterns, which may prove useful to other researchers seeking to understand the relationships between subsistence, diet, and the presence of carious lesions.

Limitations

The studied sample size is relatively small and therefore its temporal/regional distribution produces low-resolution results.

Suggestions for further research

More systematic research on the patterns of dental caries is necessary to produce more fine-grained reconstructions of diet and subsistence in Iran and around the globe.

目的分析伊朗中部高原西部边境古代墓地中三个人群龋齿的总体频率和齿间模式，以此探讨伊朗人群在大帝国建立后是否有更多机会获得发酵糖。材料来自 Kafarved-Varzaneh（青铜时代早期，MNI=66）、Estark-Joshaqan（铁器时代，MNI=57）、Tappeh Poustchi（帖木儿和萨非时期，MNI=34）的牙科藏品，以及来自叙利亚东北部的对比数据。方法使用史密斯平均差测量法、对应分析法、χ2 和 Kruskal-Wallis 检验法分析每种牙齿类别的龋齿频率、龋坏位置和大小。结论不同的生存策略可能与不同的牙间模式有关，因为埋葬在埃斯塔克的人是流动的牧民，而其他墓地则是定居的农民。意义这项对伊朗三个年代不同人群龋齿情况的综合研究揭示了龋齿与生存策略之间的关联，并引入了史密斯平均差测量法来探讨牙齿间的龋坏模式，这可能对其他研究人员了解生存、饮食和龋病之间的关系很有帮助。对进一步研究的建议有必要对龋齿模式进行更系统的研究，以便对伊朗和全球的饮食和生计进行更精细的重建。

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.

目的分析特雷门贝地层（陶巴特盆地渐新世）鸟类桡骨岩中的原生动物寄生虫。方法将样本重新水化并进行自发沉积。结果淡色寄生虫学分析发现了与埃米里科（Apicomplexa）兼容的卵囊和一个阿米巴虫（Amoezoa）囊蚴。结论本研究工作增加了有关感染在整个新生代传播的信息量，并揭示了巴西古鸟类在喙螨科和变形虫的生命周期中发挥了重要作用。这些发现有助于解释现代鸟类球虫寄生虫的系统发育，因为在目前的分子系统发育分析中，在渐新世原生动物中观察到的某些分类特征具有单系群的特征。对进一步研究的建议我们的研究结果为所述寄生虫类群的生物地理学研究提供了新的视角，并可加深对原生动物与鸟类之间寄生虫进化关系的时间幅度的理解。
