Intervertebral chondrocalcinosis: an exercise in differential diagnosis in palaeopathology

Intervertebral chondrocalcinosis (calcification of intervertebral discs and associated structures) may arise from a variety of causes. This work presents a discussion of intervertebral chondrocalcinosis and the identification of its most probable cause in skeletal remains, using as a case study a skeleton of an elderly male from medieval Ipswich, UK. The skeleton is examined using gross observation and radiography, and the intervertebral calcifications are subject to chemical analysis. In addition to intervertebral chondrocalcinosis (which has resulted in ankylosis of lumbo‐sacral segments), lesions identified include chondrocalcinosis at some synovial joints, various soft tissue calcified bodies, and severe osteoarthritis particularly at the gleno‐humeral joints. Interpretation of the results of the chemical analysis of the calcified deposits is complicated by diagenesis, but they are most consistent with apatite and/or whitlockite. Arriving at a most probable cause of the lesions in this case is difficult, but it is tentatively suggested that ochronosis may be the best diagnostic option.

Clay‐shoveler's fracture: an uncommon diagnosis in palaeopathology

An archaeological case of clay‐shoveler's fracture was observed in an adult male exhumed from a Roman necropolis dated to the 1st–3rd century AD and located in the city of Barcelona, Spain. Clay‐shoveler's fracture is a breakage of a lower cervical or upper thoracic spinous process as a result of mechanical stress. Different mechanisms have been related to this injury, generally in labour‐related contexts. This paper reviews the literature concerning this uncommon finding, focusing especially on its mechanism and on activity‐related lesions. Copyright © 2006 John Wiley & Sons, Ltd.     

Microscopical findings associated with the diagnosis of osteoporosis in palaeopathology

This paper presents some preliminary results on microscopical identification of microfractures in human skeletal remains which may be associated with osteoporosis. A technique is described for the examination of cancellous bone and applied to a number of vertebrae and one radius. All the material used is Romano-British or English medieval. However, microscopical screening for osteoporosis could form a useful part of comparative studies on historically or geographically different populations. The archaeological significance of osteoporosis in terms of skeletal ageing and nutritional status is discussed.     

中葡有关澳门主权交涉内幕——从1862年条约换文到1887年条约谈判

澳门主权问题的提出主要是在中国鸦片战争失利以后。1862年条约是葡人居澳以来中葡两国签订的第一个条约。由于葡萄牙代表在议约中采取了欺诈手段,清政府未予批准。自1864年换约失败至1887年条约谈判之前的20余年时间里,葡萄牙为了以订立条约的形式达到“合法”占据澳门的目的,曾经串通列强及其驻京公使,多次与清政府进行交涉。     

On problems of differential diagnosis in palaeopathology,as illustrated by a case from prehistoric Indiana

Because palaeopathology has to call on a limited range of evidence, compared with modern clinical diagnosis, it is important that a differential diagnosis should be broad‐based. A prehistoric case from Indiana is discussed in relation to this statement. Copyright © 2009 John Wiley & Sons, Ltd.     

Rates for the job. Measures of disease frequency in palaeopathology

Measures of disease frequency are discussed and their use in palaeopathology illustrated with examples, both hypothetical and real. It is shown that prevalence rates are the appropriate rates to use when calculating the frequency of diseases in skeletal populations. The extent to which prevalence rates accurately reflect those in the living population from which the skeletons were derived is also considered and it is suggested that they are a reasonable approximation for diseases that do not shorten life span, but not for those that do. Finally, suggestions are made for dealing with missing data.     

Tracing the ‘chemyn de Portyngale’: English service and servicemen in fourteenth-century Portugal

Three Anglo-Portuguese campaigns took English servicemen into Portugal in the 1380s. Two were largely guided by Plantagenet interests, in 1381–2 and 1386–7, respectively under the earl of Cambridge and the duke of Lancaster. The other, which began in 1384 under the regent João of Avis (later João I), involved entirely volunteer English forces. While the Lancastrian-led expeditions were largely political and military failures, servicemen recruited by the Portuguese in England achieved greater success, including victory at the Battle of Aljubarrota. This article compares these expeditions for the first time. It looks at their political, diplomatic, military, social and economic contexts, exploring motivations for English service in Portugal in particular, from that of the common soldier to that of the governments. By looking at the itineraries in Portugal of English soldiers, their presence is mapped and their continuance debated. The Anglo-Portuguese examples demonstrate how foreign military intervention and mercenary activity might be a driving force in social and economic relations between regions of Europe during the Hundred Years War.     

Using ancient DNA analysis in palaeopathology: a critical analysis of published papers,with recommendations for future work

Despite an observable increase in the number of studies using ancient DNA analysis to diagnose disease in human remains, there remain issues to be addressed about the quality of the resulting publications. This paper describes the qualitative analysis of published papers that describe the detection of pathogenic DNA in human skeletal and mummified remains from archaeological sites. Its ultimate goal is to provide an overview of the main problematic issues in relationship to standards developed in molecular biology and to make recommendations for future work. Sixty‐five papers published between 1993 and 2006 were surveyed and the quality of each was assessed using 15 criteria. Interesting results emerged. Of particular note was the high number of papers that did not acknowledge the use of even basic contamination control (90%) or procedures to validate results independently (85%). This study illustrates that attention to contamination control and authentication of results is needed in future research, if confidence in aDNA analysis in palaeopathology is to be increased. Additionally, methods of analysis must be described in published papers to ensure transparency in processes utilised to generate the data. Copyright © 2008 John Wiley & Sons, Ltd.     

Trace elements in palaeopathology: Quantitative analysis of a case of hypertrophic osteoarthropathy by instrumental neutron activation analysis

Instrumental neutron activation analysis (INAA) of the bones of a 6th century case (AD ) of hypertrophic osteoarthropathy (HOA) showed high levels of Zn, Mn and K in the periosteal new bone. The concentration of Zn in the periosteal new bone appeared to be biogenetic in origin and connected with active mineralization processes in the abnormal bone tissue. Manganese and potassium concentrations were, at least partly, related to diagenetic processes.     

The Power and Limits of Cultural Myths in Portugal's Search for a Post-Imperial Role

The central role in Portuguese political culture of the identification of Portugal as a colonizing power legitimized a massive mobilization and violent response to the perceived existential threat of decolonization in the shape of prolonged wars in its main African colonies (1961–1974). If, however, this cultural myth of a Greater Portugal overseas was so powerful, how was decolonization eventually possible? The accumulated human and economic cost of facing three simultaneous, protracted anti-colonial insurgencies eroded this overseas creed and made Catholic and Marxist strands of anti-colonialism increasingly attractive to younger, more internationally connected, Portuguese elites. What also happened, however, this article will argue, was a refashioning of the powerful cultural myth of a special connection between Portugal and tropical Africa. A colonial myth was turned into a post-colonial myth legitimizing decolonization as a mutual and fraternal liberation from the same oppressive regime without a loss of strong ‘natural’ cultural bonds. More widely, the article aims to show that we cannot ignore the importance of cultural factors in international history. Our approach in this article is pluralist and this means that while arguing strongly for taking culture seriously and focusing on it, it does consider other, including more material, dimensions of power.     

Zooarchaeological evidence for Moslem and Christian improvements of sheep and cattle in Portugal

This study of osteometric variation of sheep and cattle remains from archaeological sites in southern Portugal—the part that was once ruled by the Moslems—reveals an increase in size of the sheep in Moslem times and a subsequent increase of the cattle following the Christian conquest. It is assumed that a size increase reflects improvement. Sheep size increase is easy to understand given the Moslem fondness for mutton. The later size increase of the cattle is less easy to understand but could reflect a dietary switch from mutton to beef as well as the need for bovine power.     

Destruction of microstructure in archaeological bone: a case study from Portugal

Sampling of archaeological human bone may not be justified, contrary to former high expectations regarding adult age assessment based on histomorphometry. The alterations in buried bone as a result of bacterial action are readily visible in the scanning electron microscope (SEM). An understanding of the chemical and structural changes to cortical bone requires work at the level of a few microns. This paper reports on problems encountered during analyses of samples of human bone from Mesolithic (ca. 8000 calbp) shell midden sites at Muge in central Portugal, and the methods used to try and overcome these problems. We believe we have shown that these Mesolithic bones are partly comprised of bacterially reprecipitated mineral, which has had collagen removed, with consequent obliteration of bone microstructure. We conclude that microbial destruction of the structure of archaeological bone can be a serious impediment to analysis of the characteristics of the population represented by those skeletal remains.

Non‐osseous calcaneonavicular coalition in the Portuguese prehistoric population: report of two cases

This paper reports articular surface defects detected in three foot bones. These were exhumed from Portuguese collective burial places, Hipogeu de São Paulo II (artificial cave, Almada) and Necrópole da Serra da Roupa (shelter, Columbeira) dated to the Late Neolithic and Chalcolithic periods. Other aetiologies were presented, but non‐osseous calcaneonavicular coalition proved to be the most probable explanation for the unusual morphology detected in two calcanei and one navicular bone.

Vicarious passions: the private life of Hollywood stars in 1950s Portuguese magazines

ABSTRACT

Life in Hollywood in the 1950s seemed completely at odds with the moral foundations of authoritarian Portugal. By looking at the coverage of the lives of Hollywood stars in Portuguese magazines, however, it is possible to imagine how a conservative society could be exposed to changing values. Readers became acquainted with the period’s most famous cases of divorce. Divorce was at first seen as unacceptable, but the continuous news on the lives of famous people produced a strange impact on the Portuguese public sphere: the end of marriage became familiar and even acceptable in some circumstances. The article disentangles this paradox, by treating magazines as a mediated social actor. The foreign origin of the news may have led readers to assume that divorce was a distant phenomenon. Simultaneously, the social circulation of magazines permeated the everyday with subversive ideas. Magazines thus constitute a decisive source for exploring how North American cultural forms work through the fabric of foreign societies. Imagining the impact of Hollywood in Portugal through the mediation of magazines allows us to identify forms of social change evolving in an apparently uneventful decade, and to grasp the contribution of feelings and attitudes in historical transformation.     

Keeping to oneself: Hospitality and the magical hoard in the Balga of Jordan

ABSTRACT

Anthropologists have given copious attention to problems of exchange, of giving and receiving. Yet problems of taking, unequal accumulation, secret storage, predation, and refusal to share are no less central to social life. This is certainly the case among Jordanian Bedouin, whose notions of hospitality are a complex blend of reciprocity, protection, and coercive extraction. The families of dominant tribal shaykhs are often known for their ability to take, to store away wealth, and to protect hoards of found and inherited treasure, both magical and mundane. By reading the oral historical traditions of the Balga tribes against familiar Maussian ideas and the models of parasitism suggested by Michel Serres, I argue that hospitality, as Bedouin know it, is constructed in ways that resist the romanticism that besets anthropological portraits of ‘pre-capitalist' and ‘premodern' gift economies.     

State‐of–the–art imaging in palaeopathology: the value of multislice computed tomography in visualizing doubtful cranial lesions

Non‐invasive imaging techniques are of great value in palaeopathology. Computed tomography (CT) is widely established to visualize changes in human remains that occurred both pre and post mortem. Since 1999 an advanced form of helical CT—so called Multislice‐CT (MSCT)—has become available for clinical purposes. We now present for the first time three historic cranial lesions of doubtful aetiology visualized by MSCT. Both original images and virtual reconstructions of the specimens are of high quality. In combination with peri‐lesional bone density measurements these images allow an improved assessment of aetiology. The cases presented are diagnosed by MSCT as being of intra vitam nature in two individuals and of post mortem character in one case. Time consuming post‐processing analysis and the still small number of scanners presently available may limit application of this new technique. Nevertheless, based on our preliminary results, we strongly recommend non‐invasive evaluation by MSCT to be used for non‐clinical purposes such as palaeopathological research.

Coupling Hydrotoponymy and GIS Cartography: A Case Study of Hydrohistorical Issues in Urban Groundwater Systems,Porto, NW Portugal

The aim of this multidisciplinary study is to retrospectively examine hydrohistorical issues, namely hydrogeographic, hydrotoponymical and hydrogeological features, in order to assess the evolution of the Porto urban groundwater system (NW Portugal). To achieve these goals, the comparison of two main field inventories in a large urban region was performed by (i) historical mapping of sources and groundwater data from scientific reports spanning the late 17th century to the early 20th; and (ii) hydrogeologic and hydrotoponymical field inventory performed under current conditions. These field inventories permitted the location of springs, dug wells, fountains, public washing places and underground water galleries, which collected groundwater to supply the population of Porto until the early 20th century. This study also allowed the development of a hydrotoponymical classification for urban areas and a field hydrotoponymical inventory data sheet. This research integrated several techniques based on historical hydrogeography, hydrogeology and urban geosciences. The results of the field inventories were combined into both a database and a Geographical Information System (GIS) platform. This unified methodology allowed a cross‐check and analysis of several levels of information, namely hydrotoponymy, hydroclimatology, hydrogeology, structural geology and geomorphology. This perspective led to an assessment of the evolution of the quality of water resources in large urban areas over time. In addition, the role of hydrotoponymical features is presented in order to support the hydrogeological conceptual model for large urbanised areas.     

Pre-Columbian jadeitite artifacts from the Golden Rock Site,St. Eustatius,Lesser Antilles,with special reference to jadeitite artifacts from Elliot's,Antigua: implications for potential source regions and long-distance exchange networks in the Greater Caribbean

A detailed electron microscopy analysis of jadeitite celts from the Early Ceramic Age Golden Rock settlement on the small volcanic island of St Eustatius, Lesser Antilles, is presented in an effort to identify the source region(s) of these jadeitite axes and evaluate the extent of trade networks in the Caribbean during pre-Columbian times through which those tools (or source rocks) circulated. Habitation at the site occurred between ca. AD 230–890, and the jadeitite tools most likely date between cal. AD 600 and 825/890. We argue that in provenancing jadeitite emphasis should be placed on the identification of the entire mineral assemblage (including the accessory minerals) and textures, given the complex geological histories and processes that form this quasi-monomineralic rock. Indeed, the mineral assemblages and the characteristics of the individual minerals within the studied jadeitite samples are far from homogenous, suggesting either the source has a high degree of internal variation or there are multiple sources. We have identified three jadeitite groups among the analyzed samples on the basis of mineralogical assemblages: Group 1 consists of samples bearing phlogopite (plus phengite and epidote but without lawsonite or quartz); Group 2 contains lawsonite (plus phengite and quartz but without phlogopite and epidote); and Group 3 is defined by containing hematite. Importantly, we have not identified glaucophane in the analyzed materials. The comparison of these artifact data with those of jadeitites from the four potential known source regions of Caribbean jade, i.e., Guatemala (North and South Motagua Fault mélanges), Cuba (Sierra del Convento mélange) and Dominican Republic (Río San Juan complex) allows us to conclude that both the North and South Motagua Valley mélanges are the most likely sources for artifact groups 2 and 3, and perhaps also for group 1. This identification supports earlier hypotheses on the existence of pan-regional exchange networks, tying the northern Antilles with the Isthmo-Colombian region (Colombia, Panama and Costa Rica) during the Ceramic Age of the Caribbean.     

Traditional pig herding practices in southwest Iberia: Questions of scale and zooarchaeological implications

Archaeological interpretations are interwoven with analogical reasoning. This paper presents a large volume of ethnographic data on traditional pig husbandry in modern Iberia and discusses their zooarchaeological importance. Europe-based ethnoarchaeological studies on traditional pig husbandry (e.g., in Sardinia/Corsica and Greece) have only recently made their appearance and have been proved environmentally and geographically more relevant than similar studies carried out in Asia. This paper presents archaeologically relevant data on a great variety of themes such as pig morphology, adaptation in and exploitation of environment, herd size and composition, the relations between wild and domestic populations, castration, breeding, genetic diversity, slaughtering practices, age-at-death, home range, control and movements, diet, weight, agricultural damage and products. The results show that traditional systems of animal husbandry do survive in Europe and their study widens and improves our interpretative framework. This Iberian-based study showed that domestic pig morphology is the combined result of the breeder’s selection and the pig’s adaptation to a given environment and husbandry system. Moreover, scale is a crucial factor significantly affecting all other aspects of a husbandry system.
