Skeletal and Surgical Evidence for Acute Osteomyelitis in Non‐Adult Individuals

Osteomyelitis is a non‐specific infection of the bone and bone marrow. In the past acute osteomyelitis (AO) led to high mortality especially in non‐adults. Nevertheless, its diagnosis in archaeological populations is rare. Documented individuals with known cause of death offer a unique opportunity to study this condition. This article aims to describe the bone lesions in non‐adults diagnosed with AO at the Coimbra University Hospital (CUH) and now belonging to the Coimbra Identified Skeletal Collection (CISC). Moreover, mortality rates and demographic profiles for individuals aged ≤18 years old and diagnosed with AO in the CUH, between 1923 and 1929, were also determined. The 5 (1%) non‐adults in the CISC with AO listed as cause of death were selected for this study, and their bones were analysed macroscopically and radiologically. The skeletal remains of one individual revealed a small area of new bone formation in the shaft of the left femur. Radiography of this bone showed a radio‐opaque area in the diaphysis. The other four individuals show evidence of surgical treatment, responsible for many cases of disability in the past. In the 7‐year period under analysis, 122 juveniles were diagnosed with osteomyelitis and admitted for surgery at the CUH, 43 (35.2%) of which were diagnosed with AO. Sixty‐five per cent of the cases of AO occurred between the ages of 8 and 15 years, with boys twice as frequently affected as girls, and lower limb bones were involved in 91% of AO cases. AO was responsible for 76.9% of the deaths. This study of pre‐antibiotic non‐adults may help to recognize skeletal signs of AO and their surgical treatment in unidentified skeletal remains.

Analysis of sexual dimorphism of craniofacial traits using geometric morphometric techniques

This work deals with the assessment of cranial sexual dimorphism in human skeletal samples applying geometric morphometric techniques. The purpose of this research is to apply such techniques to quantitatively describe in craniofacial traits the degree and pattern of shape and size sexual dimorphism. Likewise, we evaluate the precision and accuracy of semilandmark‐based techniques for sex estimation. We employ a sample of 125 adult skulls of known sex from the Coimbra collection. A set of coordinate points was selected to describe glabella, mastoid, frontal and zygomatic processes. The results of intra‐class correlation coefficient (ICC) show excellent intra‐ and inter‐observer agreement (ICC > 0.96) in the location of the coordinates of points employed. The principal component analysis (PCA) performed on shape variables shows a large superposition of both sexes, suggesting a relatively low degree of dimorphism in shape. As a consequence, the average percentages of correct sex estimations based on these variables were of 60.12 and 68.90%, obtained by discriminant analysis with leave‐one‐out cross validation and k‐means clustering respectively. Conversely, when centroid size is included in PCA, females and males exhibit large separation along the first component. The highest values of correct assignment (77.86 and 72.15%) were found using shape–size variables with discriminant and k‐means clustering analysis, indicating that the traits analysed display marked sex differences related to the larger size and more robust features of males. Finally, the advantages of geometric morphometric techniques are discussed. Copyright © 2009 John Wiley & Sons, Ltd.     

The Meul Index: A non‐destructive method for estimating the cortical index in skeletal samples

The study of osteoporosis in past populations provides insight into the history and evolution of this condition. The Cortical Index is a relative measure of cortical bone often used for identifying individuals with age‐related bone loss associated with osteoporosis. Current methods of measuring the Cortical Index involve radiography or cutting actual sections of long bones at the mid‐shaft. We propose a new index, the Meul Index as means for estimating the Cortical Index without the use of radiography. Based on a preliminary study of 13 individuals consisting of 9 males, 3 females and one unknown sex, ranging in age from young to older adult, the Meul Index is highly correlated with the Cortical Index (r = 0.903). The proposed Meul Index provides a non‐destructive and inexpensive means for studying age‐related bone loss in prehistoric and historic populations represented by skeletal samples. Our research builds on the recent publication of Silva, A.M., Crubezy, E. and Cunha, E. 2008. Bone weight: new reference values based on a modern Portuguese identified skeletal collection. Int. J. Osteoarchaeol. DOI: 10.1002/oa.998. Copyright © 2009 John Wiley & Sons, Ltd.     

Sexually dimorphic sea urchins: identifying the sexes in Pentechinus mirabilis

The sexes of most sea urchin species are externally indistinguishable from one another. Where gross sexual dimorphism does exist, it is invariably associated with nonplanktotrophy. In the most extreme examples, female morphology has become modified to create depressions on the test where offspring may be sheltered throughout development. Since a number of the features used for taxonomic classification are lost on fossilization, it can be difficult to recognize fossil individuals as the dimorphic males and females of the same species. In addition, diagnoses of dimorphic taxa commonly concentrate on the striking female traits, hindering identification of the simpler male form. Here, we present an approach based on morphology and crystallographic determination of developmental mode that allows the recognition of the males of marsupiate echinoid taxa. Males of the brooding temnopleurid Pentechinus mirabilis from the Oligocene of Victoria, Australia are described for the first time.     

Universal methodology for developing univariate sample-specific sex determination methods: an example using the epicondylar breadth of the humerus

In this paper we present a new methodology for developing sample-specific metric sex determination methods using unidentified individuals that can be applied to archaeological samples. This methodology does not require the assessment of sex of a large sample from pelvic morphological features as a first step in developing the method and instead is developed from a sample of individuals with sex unknown. The procedure involves using the overall mean of a measurement collected from the sample of unknowns as the discriminant criteria for determining the sex of the individuals in that same sample. Experiments with various sample sizes and sex ratios using distal humerus measurements from the Coimbra Collection (Portugal) suggest that allocation accuracies of 83–96% can be expected when the sample used to develop the method is greater than 40 individuals and the sex ratio is less than 1.5:1. The utility of the methodology is explored using the Lisbon Collection (Portugal) and an archaeological sample from Belleville (Canada) is tested as an example. The Lisbon Collection data indicate that joint measurements of long bones will provide the highest allocation accuracies. The results from the Belleville sample confirm that humerus joint measurements consistently provide the highest allocation accuracies (88–100%) even when the sex ratio in the sample used to develop the method is estimated at 1.9:1.     

Intimate Consumption and New Sexual Subjects Among the Sambia of Papua New Guinea

This article examines the transformation of sexual meanings, attitudes, norms, and practices surrounding depletion and pollution across decades (1974–2010) among the Sambia of Papua New Guinea. In the premodern village, all sexual intercourse, whether with boy‐initiates or women, was ritualized and ultimately controlled by the men's secret society. Intimate consumption refers traditionally to a symbolic complex of beliefs, concepts, emotions, and ritual experiences involving sexuality, bodily health, social relationships, and gendered politics. But it also covers sexual anxieties corresponding to the transfer and loss of bodily fluids via the perceived depletion and pollution of self and body. For adult men, the sense of intimate consumption requires repeated substance replenishment and purification. Intimate consumption made oral and vaginal sex highly rule‐bound, taboo laden, and intensely regulated in terms of the meaning, scope, duration, and intended goals of sexual exchange. Pacification, colonization, out‐migration, Seventh Day Adventist (SDA) Christianity, and primary schooling in the Sambia Valley over a period of decades instigated social transformations that challenged and wore down this system of sexual regulation. Thus, the transition from ritual to non‐ritual practices, i.e., more individualistic sexual relationships, highlight narratives of change in the Sambia sexuality. With the demise of ritual initiation in the 1980s and 1990s, and the appearance of HIV and SikAids in the Sambia Valley, explicit ritual sexual techniques were no longer socialized. Modernity (in the sense of a set of policies, attitudes, and rules introduced through institutions such as the government community school) and SDA church sociality influenced both the pace and form of this sexual transformation. Among the greatest changes was the expansion of female agency and sexual autonomy, and personal decision‐making vis‐à‐vis especially marriage and also romance, courtship, and sex. Notably, oral sex, once universal and mandatory, largely disappeared from Sambia intimate relations. Today, spousal intimacy reveals a different set of more ‘modern’ meanings and behaviors compared to two generations ago, e.g., more mutualistic and companionate. Intimate consumption remains a worry for certain Sambia young men and women today however, influenced in part by the rise of the HIV pandemic, mobility, and the absence of normative narratives of sexuality in villages and town settlements. This creates public spaces wherein new sexual subjects have emerged in the villages and urban settlements within the Sambia Valley and in settlements throughout PNG.     

OXYGEN AND CARBON ISOTOPE ANALYSIS OF HUMAN DENTAL ENAMEL FROM THE CARIBBEAN: IMPLICATIONS FOR INVESTIGATING INDIVIDUAL ORIGINS

This study explores the potential of carbon and oxygen isotope data from human enamel carbonate (n = 50) to contribute to mobility studies in the Caribbean. Most oxygen and carbon isotope results display limited variation, with substantial overlap between islands. However, a few individuals from El Chorro de Maíta, Cuba possess relatively low δ¹⁸O and high δ¹³C. Two of these individuals were previously identified as possible non‐Antillean immigrants on the basis of strontium isotopes, and bioarchaeological and mortuary evidence. The carbon and oxygen isotope results provide additional evidence supporting the proposed non‐local origins of these individuals and contribute to explorations of their potential natal origins.     

Non‐specific indicators of stress and their association with age at death in Medieval York: Using stature and vertebral neural canal size to examine the effects of stress occurring during different periods of development

Selective mortality can occur towards individuals who survive episodes of physiological stress, such as disease and malnutrition, during development. The skeletal elements affected depend on the timing of these stressful episodes. Studying multiple non‐specific indicators of stress can show which periods of development were affected and whether certain periods can be linked with selective mortality. To examine this method a preliminary study of 61 adult individuals from the Medieval population of Fishergate House, York was undertaken to examine small vertebral neural canal size and reduced adult stature. Previous studies have shown that selective mortality occurs towards individuals who display these non‐specific indicators of stress. Statistical analysis showed that small transverse neural canal diameter was significantly associated with early adult mortality for males and females and there was evidence of selective mortality towards females with reduced stature. This suggests that individuals who died in early adulthood experienced health insults during late childhood which stunted VNC growth but males in particular were not significantly affected by health insults after this age as they achieved a normal adult stature. Therefore it appears that health insults which occurred during late childhood had a greater influence on adult health in the Fishergate House population. This method could be expanded to provide more detailed information by using a greater variety of non‐specific indicators of stress which will allow more specific periods of development to be investigated.

Interpreting diachronic osteological variation at the medieval necropolis of the Sant Pere Churches (Terrassa,Spain)

The purpose of this study is to analyse the diachronic variation in the skeletal sample exhumed from the medieval necropolis of Sant Pere Churches, interpreting the results using the archaeological and historical evidence. The Sant Pere Churches are a monumental Romanic complex located in Terrassa (Spain) and built over the earlier Episcopal Cathedral of Egara from the Visigoth period. Egara has traditionally been considered the precursor of the current city of Terrassa; however this name disappeared from historical documentary sources after the period of Muslim incursions into Hispania (8th century). An archaeological excavation undertaken recently at the Sant Pere Churches provided us with the opportunity to study the population that was interred in this complex during that epoch. In total, the skeletal remains of 208 individuals were examined. In order to analyse the diachronic variation, the sample was divided into two periods, that of the Cathedral of Egara (4th–8th centuries; N = 128) and that of the Parish Churches of Terrassa (9th–13th centuries; N = 80). Both periods of the complex exhibited a similar skeletal age distribution, including under‐representation of non‐adult individuals. Nevertheless, a bias towards males in terms of sex distribution, sex differences in the mortality level and greater sexual dimorphism were observed in the population interred at the Cathedral of Egara. Moreover, analysis of the prevalence of skeletal disorders also provided evidence of higher differences between sexes for the period of the Episcopal Cathedral of Egara, the female population exhibiting the lower prevalence. Additionally, diachronic variation in both postcranial and dental disease patterns was observed, suggesting different activity patterns and food consumption between the periods. Overall, the results suggested that diachronic osteological variation observed in the Sant Pere Churches skeletal sample was most probably linked with the changes in the role of the complex following the Muslim incursion of the 8th century.

New Statistical Approaches to Intra‐individual Isotopic Analysis and Modelling of Birth Seasonality in Studies of Herd Animals

This paper introduces improved methods for statistically assessing birth seasonality and intra‐annual variation in δ¹⁸O from faunal tooth enamel. The first method estimates input parameters for use with a previously developed parametric approach by C. Tornero et al. The second method uses a non‐parametric clustering procedure to group individuals with similar time‐series data and estimate birth seasonality. This method was successful in analysing data from a modern sample with known season of birth, as well as two heterogeneous archaeological data sets. Modelling indicates that the non‐parametric approach estimates birth seasonality more successfully than the parametric method when less of the tooth row is preserved. The new approach offers a high level of statistical rigour and flexibility in dealing with the time‐series data produced through intra‐individual sampling in isotopic analysis.     

Several Infra‐cranial Non‐metric Variations in a Single Neolithic individual: A Common Genetic Underlying Predisposition?

Non‐metric variations have been the subject of anatomical and anthropological studies for more than a century. In this study, we present an individual from Sion (Canton of Valais, Southern Switzerland) dated from the Middle Neolithic who shows evidence for four non‐metric variations. This young adult male presents an os acromiale, spondylolysis, a bipartite patella, and bilateral calcaneus secundarius. These non‐metric variations have a low frequency in most populations (less than 10%), and for each of them the origin is usually considered to be genetic, environmental, or a combination of both. This case is of interest for understanding the potential genetic origin of these non‐metric variations as well as for demonstrating their usefulness in bioarcheological analysis.

Pathogenesis of apical periodontal cysts: guidelines for diagnosis in palaeopathology

Apical periodontal cysts are benign lesions developing in relation to the apices of non‐vital teeth due to inflammatory response from the infective pulp. These are epithelium‐lined bony cavities containing fluid. Despite being widely reported in medical/dental literature, this common condition is poorly diagnosed and documented in the archaeological literature. We aim to clarify the correct terminology, demonstrate bony manifestations at different stages of pathogenesis of chronic periapical dental lesions into granuloma and apical periodontal cysts, and to describe diagnostic criteria which would provide practical guidelines for the diagnosis of these conditions. Three identified skulls from the International Exchange Collection, housed in the Anthropological Museum at the University of Coimbra, are used to identify the progression of this condition from a small periapical granuloma to a large apical periodontal cyst with expansion of alveolar and facial bones. The pathogenesis of this condition is described, together with its surgical management in the early 20^th century in Portugal, which is the period in which these individuals lived. Confusion resulting from the different terminologies can be avoided if the term periapical granuloma is used to define apical bony lesions smaller than 3 mm at their maximum intra‐bony diameter, and the term apical periodontal cysts for the larger lesions. We recommend that these terminologies and parameters be used as a standard in future studies. This will make inter‐observer and inter‐population comparisons more accurate.

Sex identification from the auricular surface of the adult human ilium

The sacro-iliac joint has largely been excluded in studies of sex identification from the adult human skeleton. Yet this is a joint involved in the transmission of body weight and as such would be expected to exhibit sexual dimorphism. In addition, the auricular surface of the ilium tends to persist even in fragmented remains by virtue of its close proximity to the acetabulo-cristal buttress. The aim of this investigation was to assess the accuracy with which sex could be predicted from dimensions of the auricular surface of the ilium. Significant sex differences were found in the size and shape of the auricular surface. However, these differences were of insufficient magnitude to permit discrimination between the sexes with any acceptable degree of accuracy. Therefore, the auricular surface of the ilium is not recommended for the purpose of sex identification.     

Rural Rickets: Vitamin D Deficiency in a Post‐Medieval Farming Community from the Netherlands

Rickets is caused by vitamin D deficiency as a result of limited exposure to sunlight and inadequate diet. In the 19^th century, rickets was endemic in most northern European cities. In post‐Medieval Netherlands, rickets is documented in low frequencies in a few urban samples, but has not been studied in contemporaneous rural populations. Beemster is a rural farming community in the Netherlands that was established in the 17^th century upon drained land, with the Middenbeemster cemetery in use until 1866 AD. Ninety‐five individuals from the ages of 32 weeks in utero to 15 years were examined for rickets in order to understand factors that can cause vitamin D deficiency in rural, non‐industrialized populations. To identify rickets in the Beemster sample, ten features were scored, with bending deformities of the lower limb and one other feature, or at least three non‐bending features, having to be present in order for diagnosis. Nine individuals (9.5%) had evidence of rickets—a high prevalence, especially for a rural community where ample sunlight was available. The two and three year old Beemster infants were most heavily affected with an age‐specific prevalence of 30.4%. Two three‐month‐old infants also had rickets. Some of the affected may have developed rickets secondarily, as a result of a different illness, but cultural practices including prolonged swaddling, occlusive clothing, and keeping the young indoors, are suggested to have contributed to this high rickets prevalence. Dietary variables including poor weaning foods and common episodes of malnutrition may have also contributed to vitamin D deficiency. This study demonstrates the value of careful analysis of pathological conditions in subadults and highlights that rickets was not only a disease of cities, but affected populations that would appear to have been at low risk, because of maladaptive cultural practices.

Directional bilateral asymmetry in human sacral morphology

Directional bilateral asymmetries in human gross skeletal morphology are largely attributable to differential mechanical loading from handedness during endochondral bone growth. While much has been done in the way of identifying directional asymmetries of the upper limb in relation to handedness, comparatively little research has focused on asymmetry in the lower body. The present paper analyses asymmetry in the human sacrum in a sample of 238 modern individuals. Measurements of right and left sides of the lateral and posterior breadths of the alae and the maximum height of the auricular surface were used. Asymmetry was calculated as: [(left side − right side) ÷ right side] * 100. Directional asymmetry was identified using a one‐sample t‐test against a hypothesized mean of zero. Significant directional asymmetry (P < 0.05) was found in all three dimensions. The pattern of asymmetry is consistent with models describing the influence of right‐handedness on the lower body, which predicts that left side dimensions will be larger.

Isotopic Evidence for Marine Consumption and Mobility in the Atacama Desert (Quillagua,Northern Chile)

Archaeological research in the Atacama Desert has recovered evidence of considerable cultural variability. This variability seems to have increased during the Late Intermediate Period (AD 950–1400). The oasis of Quillagua, located at the margins of the Loa River in northern Chile, between the Andes and the coast (70 km from the Pacific Ocean), has shown important evidence regarding this cultural diversity. The variety in the archaeological evidence found at Quillagua has been interpreted as the result of two different cultural influences at the oasis: the Pica‐Tarapacá who occupied the coastal and inland regions to the north of Quillagua and the Atacama who occupied the oasis and fertile areas southeast of Quillagua. Here, we present the results of stable carbon, nitrogen and oxygen isotope analyses of 23 individuals recovered from the Cementerio Oriente in Quillagua, in order to test whether the observed cultural variability is also reflected in diet and mobility patterns. Results from carbon and nitrogen isotope measurements indicate the importance of marine protein, as well as a contribution of maize in the diet of some individuals. Four individuals show low δ¹⁸O values, suggesting a possible highland or non‐local origin, whereas values for the remaining individuals are consistent with lowland populations. Together, the results support the idea that the Quillagua oasis represented an important site of interaction between the Tarapacá and Atacama cultures, with close contacts with the coast but also with the presence of individuals from the highlands.

Multiple Injury and Health in Past Societies: An Analysis of Concepts and Approaches,and Insights from a Multi‐Period Study

Earlier clinical and bioarchaeological studies found that injury recidivists were most likely to be young adult males. Since then, the clinical meaning of the injury recidivist has expanded to include all individuals with multiple injuries, and other aspects of health have been considered. Our study sought to apply these advances to paleopathology and place multiple injuries in a wider context by investigating: the age and sex distribution of those with single and multiple fractures, and if people with multiple injuries had poorer general health. The sample of 213 males and 190 females (≥18 years old) from six populations in England, Siberia, and Sudan ranged in date from the 3rd century BC to the mid‐19th century AD. Health variables included cribra orbitalia, porotic hyperostosis, periostitis, Schmorl's nodes, enamel hypoplasias, dental caries, and periodontitis. Ante‐mortem injuries were: fractures (0/1/≥2), myositis ossificans, dental trauma, and sharp‐force injuries. The data were analysed using chi‐square and hierarchical loglinear analyses (P = 0.05). No significant three‐way association between age, sex, and injury was found. There was no difference between the sexes when individuals with single versus multiple injuries were compared. There were significant differences in the age‐distribution of people with 0 and 1/≥2 fractures. Males and those 26–35 years old were most likely to have fractures and multiple injuries. Porotic hyperostosis was significantly associated with fractures. There was no significant relationship between general poor health and multiple injuries.

Marriage,Sex, and the Church of Scotland: Exploring Non‐Conformity Amongst the Lower Orders

The history of marriage amongst the Scottish lower orders in the eighteenth century has largely been a story of sexual discipline by the Kirk (Church of Scotland). As much of this history has been produced through kirk session records — the arm of the church that monitored sexual morality and marital conformity — this is often construed as a story of contest between the church and a resistant lower orders, trying to negotiate alternative forms of family life. Using kirk session and secular court records and popular literature, this article explores how religious belief shaped sexual and marital behaviour, particularly non‐conformity, during this period. It examines the Kirk's interpretation of chastity and marriage, how these ideas filtered into popular culture and were used by the lower orders to negotiate their own sexual and marital behaviour and relationship to the Church. It argues that the Kirk's varying attitude to marital and sexual non‐conformity meant that marital non‐conformity was less significant than sexual sin in the popular and religious imagination.     

Stature estimation in a central Patagonian prehispanic population: development of new models considering specific body proportions

Stature estimation of individuals from extinct human populations is a classic topic in anthropology. The estimations, using regression formulae generated from different reference samples, display different results. This fact is related to inter‐populational differences in body proportions, which is a phenotypic trait mainly correlated with climatic parameters. The aim of this paper is to address the problem of stature estimation of an archaeological skeletal sample from Patagonia – a region for which there are no specific models available – using different methods and considering differences in body proportions between reference and target populations. The sample used in this analysis is composed of 35 Late Holocene adults of both sexes recovered in central Patagonia (Argentina). The stature of each individual was first reconstructed using the anatomical method [Fully G. 1956 . Une nouvelle me´thode de de´termination de la taille. Annales Medicine Legale 35 : 266–273], which has no assumptions on body proportions. The results were compared with estimations based on 32 different regression formulae [Trotter M, Gleser G. 1958. A re‐evaluation of estimation of stature based on measurements taken during life and the long bones after death. American Journal of Physical Anthropology 16 : 79–124. 10.1002/ajpa.1330160106] and three femur/stature ratios [Feldesman MR, Fountain RL. 1996. Race specificity and the femur/stature ratio. American Journal of Physical Anthropology 100 : 207–224. 10.1002/(SICI)1096‐8644(199606)]. The average reconstructed stature was 160.8 cm for females (95% confidence band = 155.6–166.2 cm), and 170.5 cm for males (95% confidence band = 168.8–172.2 cm). Most of the comparisons of the regression formulae and femur/stature ratios showed significant differences, which are explained by differences in body proportions between the Patagonian sample and the ones chosen as reference. Finally, a set of new equations was developed using simple regression techniques. It is suggested that whenever possible, population‐specific formulae should be used in archaeological studies. In any other situation, the choice of a reference population should be made by taking into account its geographic (latitudinal) provenance. Copyright © 2009 John Wiley & Sons, Ltd.
