Osteochondroma in a skeleton from an 11th century Croatian cemetery.

We present a case of a well-preserved bone tumor in a skeleton from a Croatian skeletal series dated to the 11th century AD. The tumor is located on the anterior side of the neck of the right femur. The gross morphology of the tumor - a round, lumpy, cauliflower-like appearance with a fairly smooth external surface - is consistent with osteochondroma. The diagnosis is supported by x-ray and CAT-scan findings, which show thickened trabeculae and an internal structure of cancellous bone interspersed with areas of dense compact bone. Comparison with x-rays from a patient surgically treated in 1999 for an osteochondroma with the same localization shows that the characteristics of the tumor have remained unchanged from the 11th century.

[Molecular genetic analysis for taxonomic determination of fossil skull fragments of Warendorf-Neuwarendorf].

The isolation and examination DNA segments from prehistoric and fossil bone samples has become one of the biggest challenges in anthropology within the past years. By using specially developed and/or adapted genetic methods, it is possible under laboratory conditions to amplify portions of DNA from bone remains in states of good preservation by the polymerase chain reaction (PCR). DNA sequence data can provide far more specific answers to palaeanthropological questions than one would expect solely by morphologic comparison. Here we introduce an alternative approach for the classification of total ancient DNA by means of Southern hybridisation techniques.

Use of the hand bones roentgenographs in the prediction of age in nine human populations.

The major aim of this study was to develop an accurate method of age prediction for a wide range of ages, based on the roentgenographic assessment of the hand bones, for use in paleoanthropology and forensic medicine. The roentgenographs of the hand bones were assessed in 5756 individuals, 2683 males and 3073 females, aged 17-93 and 17-89, respectively, belonging to 9 ethnic groups from the former USSR, Israel, and Sinai peninsula (Egypt). For each roentgenogram an equidistant osteographic score (OSS) including the descriptive criteria of bone age, such as (1) osteophytes or nodes of Heberden in the periarticular regions and at sites of tendon attachment, (2) manifestations of osteoporosis, (3) signs of sclerosis, and (4) non-traumatic articular deformities, was estimated. Regression analysis, that included linear, non-linear, logistic, and stochastic models, was used to evaluate the relationships between age and OSS. This relationship was best described by a logistic regression function. Results of the logistic regression analysis clearly indicate that OSS is a strong predictor of an individual's age, with r2 values ranging from 0.671 to 0.901 (p < 0.001). Our standard errors of estimate were ranging from +/- 4.2 to +/- 7.3 years, comparing favorably with most known methods of bone age assessment. This study provides an efficient method of age prediction, which allows to extend the upper limit of prediction to the age of 70 years with acceptable accuracy.

Anthropological and palaeopathological analysis of the human remains from three "Tombs of the Nobles" of the necropolis of Thebes-west, upper Egypt.

During several recent excavation campaigns at the necropolis of Sheikh-Abd-el-Gurna, Thebes-West, Upper Egypt, we investigated the human remains of three "Tombs of the Nobles" totalling at least 273 individuals. The investigation covered the human material (skeletons and mummy residues) from the tombs TT-84, TT-85 and TT-95. These tombs had been built in the New Kingdom (approx. 1500-1000 B.C.) and used until the Late period (up to 330 BC). All samples were analyzed macroscopically, isolated findings were further investigated by endoscopic and radiological techniques. The at least 273 individuals covered an age range from newborns to senile individuals with a main age of death between 20 and 40 years of age. The rate of infants and subadults was at 20.2% of all individuals and there was a slight male predominance comprising 54.5% of the adults. In this population a fairly high rate of pathological lesions was seen. Thus, dental conditions generally were poor with a high degree of dental abrasion, an also high rate of carious dental lesions (affecting between 13.8% and 27.7% of the yaws) and consequently a significant number of dental abscesses (mean 15.9%). Residues of trauma were observed in a considerable number of individuals ranging between 12.3% and 22.6% depending on the burial place (mean 15.8%). Inflammatory bone reactions (except the dental abscesses) were present to variable extent, in some locations ranging up to 6.8% of the cases (mean 5.1%). In addition, we noted several cases showing cribra orbitalia (mean 29.2%) and porotic hyperostosis (15.4% of cases), mild to severe osteopenia (7.5%) and in several cases subperiosteal new bone formation suggestive of chronic vitamin D-deficiency ("scurvy") (9.5%). The data support the notion of a significant impairment of living conditions in a high number of individuals. The rates of osteoarthrotic joint alterations were considerably variable depending on the burial places (between 1.9% and 18.5%) providing insight into the physical activities of subpopulations in different locations of the burial places. Similarly, the rate of spondylosis showed also variable extent ranging between 12% and 66.1% of vertebral bodies. In general, our analysis provides evidences that the living conditions in the ancient Egyptian population of one of the main necropoles of Thebes analyzed in this study were quite poor. This is somewhat in contrast to the usually assumed high standard of living of the socially higher population of the capital of ancient Egypt.

Biochemical and palaeopathological investigations on weaning and infant mortality in the early Middle Ages.

Weaning age of the children of the early medieval population at Wenigumstadt (Ldkr. Aschaffenburg, southern Germany, 500-700 AD) was estimated by stable nitrogen isotope analysis of bone collagen. The onset of weaning was by one year of age, when solid vegetal food subsequently replaced breast milk. In total, the change from mother's milk to solid adult food took about three years, the infants being fully weaned at this age. While the growing infant was sufficiently supported in utero and during the first months of life, the weanling's diet was insufficient for further growth and development. Starting with about 18 months of age, more and more symptoms of malnutrition are detectable on the skeletal remains, and the peak of both morbidity and mortality is reached at four years of age. Especially unspecific stress markers like Harris' lines and enamel hypoplasia clearly indicate the infants' risk of falling ill or die between three and four years of age. Malnutrition weakens the immune response, therefore the majority of inflammations detectable on the skeleton are found among the inadequately nourished children. The assumption that weaning is responsible for pathological skeletal lesions and early death in history is thus supported by archaeometry.

[A 2500 year-old patient. Nosological study of a statue of the Nok culture, Nigeria].

The authors describe a terra cotta statue of the Nok culture (Nigeria) dating from between 450 and 50 B. C. Amongst thousands of the same origin, this statue is the only one representing a pathological state of cirrhosis, aetiology of which may be viral, parasitological or iatrogenic. Although no precise diagnosis can be made, this statue pays tribute to the power of observation of the artist who conceived it.

Morphological and biomechanical analysis of a skeleton from Roman imperial necropolis of Casalecchio di Reno (Bologna, Italy, II-III c. A. D.). A possible case of crutch use.

A Roman skeleton (T.130) from the roman necropolis of Casalecchio di Reno has been studied in order to understand if the hypothesis of crutch use, suggested by the severe articular degeneration at the hip joint that caused evident reduction of his locomotory possibilities, could be supported by the morphological alterations of other bones and joints. The pathological changes and muscular development of the upper limbs and shoulder girdle bones suggest that these parts were submitted to a great mechanical stress. The observations are consistent with the hypothesis of crutch use that would have involved a new weight-bearing function of the upper limbs in order to help locomotion, even though it is difficult to assess the number and type of the crutches. The comparison with other possible cases of crutch use reported in literature gives an additional support to the interpretation of the findings.

Dentistry in ancient mesopotamia.

Sumer, an empire in ancient Mesopotamia (southern Iraq), is well known as the cradle of our modern civilization and the home of biblical Abraham. An analysis of skeletal remains from cemeteries at the ancient cities of Ur and Kish (circa 2000 B.C.), show a genetically homogeneous, diseased, and short-lived population. These ancient Mesopotamians suffered severe dental attrition (95 percent), periodontal disease (42 percent), and caries (2 percent). Many oral congenital and neoplastic lesions were noted. During this period, the "local dentists" knew only a few modern dental techniques. Skeletal (dental) evidence indicates that the population suffered from chronic malnutrition. Malnutrition was probably caused by famine, which is substantiated in historic cuneiform and biblical writings, geologic strata samples, and analysis of skeletal and forensic dental pathology. These people had modern dentition but relatively poor dental health. The population's lack of malocclusions, caries, and TMJ problems appear to be due to flat plane occlusion.

Valsequillo biostratigraphy. IV: Proboscidean ecospecies in Paleoindian sites.

Five proboscidean species have been found in Paleoindian sites from North to South America: two open-country adaptations, Mammuthus columbi and Cuvieronius tarijensis, two woodland and riparian forms, Mammut americanum and Mammuthus jeffersonii, and one tropical savanna species, Haplomastodon chimborazi. Their value in biostratigraphy and as ecological index fossils is discussed with particular emphasis on the Central Mexican Paleoindian sites.

Disease in the neolithic population of the Lengyel culture (4300-4000 B.C.) from the Kujawy region in north-central Poland.

In this paper the skeletal sample from Osłonki near Włocławek (Kujawy region) is analysed. It is dated back to 4300-4000 B.C. The material consists of skeletal remains of 92 individuals (being one of the largest samples from the neolithic period in Poland). Skeletons were examined for the presence of congenital malformation, traumatic and degenerative changes, diseases of the masticatory system, and cribra orbitalia. Some interesting results have been achieved by comparing the incidences of diseases regarding sex groups: pathological alterations were observed with greater frequency in male than female skeletons.

Diet and age-at-death determinations from molar attrition. A review related to the low countries.

To elucidate the impact of diet on age-at-death determinations based on molar attrition a comparison was made between the established rate of attrition in three populations; a pre-mediaeval (British), a late mediaeval (Dutch) and a 17-18th century (Dutch) (western European). It appeared that the rate decreased dramatically during the overall time span and that this change was probably diet related and owing to the coarseness of foodstuffs. This result strongly indicated that molar age-attrition tables should only be used for age-at-death determinations if their application is restricted to a particular cultural period and diet.

[Paleobiology in the population of Herculaneum (79 A.D].

The anthropologic examination of the human skeletal remains recovered on the ancient beach of Herculaneum provides a unique opportunity for gaining paleobiological data on a Roman population. The eruption caught the people on the ancient beach as they were trying to escape; the volcanic surges and pyroclastic flows had different effects on them depending upon where they were on the beach. Those caught in the open suffered immediate dehydratation, with cranial explosion and complete burning of bones, whereas those trapped in the boat sheds suffered slower dehydration. Histological analysis of the bone remains reveals an exposure to temperatures of 350-400 degrees C; the slower dehydratation of those in the sheds resulted in the preservation of some soft tissues, which are exceptional findings.
