Metaphyseal fibrous defects in juveniles from medieval Norwich

Two juvenile skeletons excavated from medieval Norwich each have a well‐defined cystic cavitation. One involves the distal femur and the other the proximal tibia. The dry bone and radiographic appearance, as well as the location and age of the individuals, support a diagnosis of metaphyseal cortical defects. Although well‐known in clinical practice, especially in children, this appears to be the first published evidence for the condition in British archaeological material. No other anomalies were detected on the two skeletons. However, the occurrence of two cases in the same cemetery raises the possibility of a genetic influence in the condition.

Stafne's defects in two mandibles from archaeological sites in Croatia

Salivary gland inclusions in the mandible are relatively uncommon in recent as well as archaeological populations. This condition is well known to oral surgeons, but less so to anthropologists, osteologists and skeletal biologists. At present a limited number of reports pertaining to this condition in ancient populations are available in anthropological and palaeopathological literature, although scattered reports of cases in recent populations are found in dental journals. This paper analyses the prevalence of Stafne's bone defect in a large composite Croatian archaeological series (n = 4250 mandibles), and reports on two cases in which computerised tomography was performed, in order to draw the attention of anthropologists, osteologists and skeletal biologists to this condition when faced with differential diagnosis of odontogenic lesions, cysts and neoplasms in the area of the angle of the mandible.

Lingual cortical mandibular defects (Stafne's defect): an anthropological approach based on prehistoric skeletons from the Canary Islands

While posterior lingual mandibular depressions (Stafne's defect) are often discussed in clinical reports, they are rarely the subject of anthropological research. This situation is paradoxical since osteologists and skeletal biologists are in a position to enhance understanding of the trait's aetiology by systematically recording the trait in recent and prehistoric skeletal collections. This report reviews anthropological studies of cortical defects of the mandible, recommends a protocol for recording observations in trait variation, and presents new data for the prevalence of Stafne's defect—lingual cortical defects of the mandibular corpus. Among the Guanches of Tenerife in the Canary Islands (Spain), the prevalence of lingual cortical defects is 3.32% (15/452), males are more frequently affected than females, and there is a tendency for individuals with antemortem tooth loss to display larger lesions than individuals without antemortem loss of teeth. Defects of the left side are somewhat more variable in position than defects located on the right. In comparative perspective, prevalence of lingual cortical defects among the Guanches is high, given the overall 1.07% prevalence reported for archaeological series (Finnegan & Marcsik,1980), but is similar to figures reported for the Avar period sample from Hungary 3.73%. Prospects for the use of lingual cortical defects as non‐metric traits of value in population distance studies remain uncertain since variation in trait expression may have a high environmental component. However, if human osteologists routinely include observations of lingual mandibular cortical defects in their analysis of skeletal collections, the data required to elucidate factors responsible for the trait's cultural, ecological, temporal and geographical patterning will more rapidly become established.

明中叶以来史学考据的兴起及其成就与缺失

由于明朝官方所修国史失实,私家修史存在比较严重的曲笔、讳饰等现象,因此明中叶以来史学考据应运而生。首开史学考信风气之先的是王世贞,其代表作《史乘考误》是明代首部对当代史史料进行考证的著作。其后焦竑、朱国桢、张燧、朱明镐、谈迁、钱谦益等人在考史方面都取得了不小的成绩,同时也存在着一定的缺失。     

Polydactyly in the prehistoric American Southwest

General surveys of skeletal collections from Arizona for evidence of trauma and pathology led to the identification of polydactyly in two subadults. Polydactyly is a congenital condition characterised by the presence of extra digits on the hands or feet. Both affected subadults exhibit a sixth digit in the form of a branching fifth metatarsal. One of the affected individuals is an infant from the Tapia del Cerrito site exhibiting Y‐shaped fifth metatarsals indicative of postaxial type A polydactyly. The second individual is a juvenile from the Nuvakwewtaqa (Chavez Pass Ruin) site exhibiting a left fifth metatarsal with a lateral branch, also diagnosed as postaxial type A polydactyly. These two cases appear to be the first examples of polydactyly from archaeological contexts identified among subadults, and bring the total number of known cases from the American Southwest to six. Discovery of so many examples of this relatively rare condition amongst the Puebloan people of the Southwest adds to the evidence that, rather than simply being an artistic motif, rock art depictions featuring hands and feet with six digits were probably inspired by observation of the condition amongst living people. Furthermore, burial treatment of the Tapia del Cerrito infant suggests that polydactyly may have conferred a special status on the bearer. Copyright © 2006 John Wiley & Sons, Ltd.

A bipartite patella in a juvenile from a medieval context

One hundred and thirty six well‐preserved medieval skeletons were excavated in advance of re‐development in Norwich. The right patella of a 13–15 year old skeleton (SK 65) displays a ‘fracture line’ running through the supero‐lateral pole. This represents the fusion of a secondary ossification centre, a condition known as bipartite patella. It should not be confused with other anatomical variants or with pathological processes.

Stafne's Defects in a Sample of Adult Thai Mandibles in the Khon Kaen University Osteology Collection,Thailand

Examination of 311 adult dry‐bone mandibles from Thailand revealed 8 examples of Stafne's defects in the region of the submandibular salivary gland. This study revealed that some radiographic studies may under report the actual frequency of shallow or early‐stage Stafne's defects that lack sclerotic rims.     

Study of stafne's defects in Late Neolithic,Late Roman,Medieval and Modern skeletal samples from Portugal

Lingual mandibular cortical defects (Stafne's defects) are relatively uncommon in recent as well as past populations, but while this condition is often discussed in clinical reports, they are rarely the subject of anthropological research. In this paper, the prevalence of Stafne's bone defects in skeletal samples from Late Neolithic, Late Roman, Medieval and Modern Portugal is investigated (N = 704 complete mandibles and 111 incomplete mandibles). The aims of this paper are threefold: (1) to present and analyse for the first time in Portuguese osteological record prevalence data on Stafne's bone defect, (2) to analyse variations in defect prevalence between skeletal samples from a wide temporal array and (3) to verify if more tenuous lesions in which resorption of the lingual cortex was not yet extensive had the classic radiographic appearance described by Stafne in order to validate the hypothesis that lesions are present clinically in many more cases than published figures indicate. In all cases, differential diagnosis against other conditions that mimic Stafne's defects, namely odontogenic lesions, cysts and neoplasms, was done. In all samples, the evidence of Stafne's defect occurred in 12 individuals (1.7%), and males (2.84%) were more frequently affected than females (0.61%). When incomplete mandibles were considered, only one left fragment (0.90%) exhibited Stafne's defect. Accurate identification of all examples of Stafne's bone defects in antiquity is thought to represent an important contribution to elucidate which factors may be responsible for this trait's cultural, ecological, temporal and geographical patterning.

Possible Evidence for Homicide in an Egyptian Mummy Head

In the present paper we describe the macroscopic, radiological and histological findings for the head of an adult male Egyptian mummy, who presented with a round to oval defect of the left occipitotemporal bone covered by an almost intact layer of soft tissue and skin. The osseous defect showed infundibular widening into the cranial cavity, such as is seen in cases of depressed fracture due to a massive external force applied by a rather blunt weapon. In addition, the slightly increased thickness of the skull bone indicates that even higher mechanical force was necessary to punch out the defect than in other skulls. Because we assume that the defect occurred intravitally, the unusual constellation of this defect provides some evidence that it had occurred during a violent attack, possibly presenting the palaeopathological remnants of a case of homicide.
