Violence in the Early Bronze Age. Diagnosis of skull lesions using anthropological, taphonomic and scanning electron microscopy techniques.

In this paper we present the study of a skull belonging to a young male from the Italian Bronze Age showing three perimortem injuries on the frontal and parietal bones; the peculiarity of the frontal injury is represented by its singular shape, which may be indicative of the weapon that caused the lesion. The aim of the present study is to examine the traumatic evidence in relation to possible etiological factors, in order to attempt to establish if the lesion occurred peri or post-mortem, and to evaluate if these traumatic injuries could be interpreted as an evidence of interpersonal violence, by combining anthropological, taphonomic and ESEM investigations. The combination of multidisciplinary methods of study can provide important new insights into inter-personal violence.

Diaphyseal cross-sectional geometry of the metatarsal bones in the Jomon population.

OBJECTIVES: This study aimed to investigate differences in the diaphyseal cross-sectional geometry (CSG) of the metatarsal bones (MTs) between two populations with different habitual activities: the Jomon hunter-gatherers and modern Japanese people. MATERIALS AND METHODS: We evaluated the first through fifth MTs of 117 skeleton samples: 59 (33 men and 26 women) were obtained from Late and Final Jomon period archeological sites and 58 (31 men and 27 women) were from modern Japanese people. CSG properties were calculated at the mid-shaft of the MTs and the relative values of the polar section modulus (Zp ) of each second-to-fifth MTs to first MTs were calculated. These variables were compared according to population and sex. RESULTS: Many of the CSG properties of MTs, except first MTs, were higher in the Jomon population than in the modern Japanese population for both sexes. Additionally, the relative values of the Zp of the MTs were higher in Jomon men and women than in modern Japanese men and women. Moreover, the Jomon population had sex-based differences in the ratio of the shape of third MTs and fourth MTs and the relative MTs value. Jomon women had elliptical third MTs and fourth MTs, and the relative Zp values of the third-to-fifth MTs to first MTs were higher in Jomon women than in Jomon men. DISCUSSION: Our result suggests that the habitual activity of the Jomon population placed heavy loads on the forefoot. This finding possibly relates to mediolateral forefoot loading that appears to be related to traversing uneven terrain.

A brief history of tuberculosis in the Czech Lands.

Tuberculosis currently remains a serious medical problem, therefore increased attention is being paid to this disease. Paleopathological studies focused on the monitoring of morbid changes in skeletal remains of historical populations facilitate a detailed study of the development of this disease. They provide direct evidence of the existence of tuberculosis and its past forms. In addition to literary and iconographic sources, the present study is focused on recording the findings of bone tuberculosis in historical osteological sets from the Czech Lands and is the starting point for their detailed review. Approximately 76 cases of bone tuberculosis from the Czech Lands have been published and more or less reliably documented from 20 archeological sites dated back from the Eneolithic to the modern period.

Bone mineral density of skeletal remains: Discordant results between chemical analysis and DXA method.

Dual-energy X-ray absorptiometry (DXA) scanning is a gold standard for bone mineral density measurement and diagnosis of primary and secondary osteoporosis in living persons. DXA is becoming widespread when analysing archaeological material, and is considered to provide an accurate diagnosis of osteoporosis in skeletal samples. The aim of this study was to explain the differences in results between bone mineral density (obtained with DXA) and chemical determination of calcium and phosphorus concentrations in skeletal remains. We examined bone mineral density (BMD) and mineral content of femoral bone samples exhumed from mass graves of the Second World War. BMD was determined by Hologic QDR 4500 C (S/N 48034) Bone Densitometer. Concentrations of calcium and phosphorus were determined with AAS (Atomic absorption spectroscopy) and UV/VIS (Ultraviolet-visible) spectroscopy. The results obtained in this study do not support the hypothesis according to which BMD measured by DXA scan has positive correlation with chemically determined concentrations of calcium and phosphorus in bones, especially in acidic soils where there was significant impact of diagenesis observed.

Timing of maxillofacial-oral injuries in an individual of the ancient city of Herculaneum (79 AD, Naples, Italy): a case report.

BACKGROUND: This study is based on the skeletal remains of an adult female from the ancient city of Herculaneum (Naples, Italy), who was a victim of the eruption of the nearby Vesuvius Volcano on 24-25 August, AD 79. RESULTS AND DISCUSSION: Examination of the maxillofacial region revealed evidence of unilateral condylar fracture and dislocation, as well as traumatic dental injuries. The injuries observed might have been the consequence of a direct blow to the mental region that was transmitted in a direction that raised the mandible, causing an indirect fracture in the right condylar neck when the condylar head collided directly with the temporal glenoid fossa. This indirect impact also resulted in partial fracture of three dental crowns due to the violent impact of the arches between them, and the sharp impact together of the upper and lower teeth. It is suggested that these injuries were sustained due to an accidental fall when the individual was between 7 and 15 years old, which is supported by the morphology, location and extension of the injuries, and the characterization of the impact. CONCLUSION: These results are an illustration of how dental anthropology and forensic approaches can be applied with great benefit to archaeological skeletal remains.
