Analysis of cribra orbitalia in the earliest inhabitants of medieval VilniusThe purpose of this work is to present an analysis of cribra orbitalia (CO) from the population of a medieval cemetery in Vilnius, Lithuania, dated between the end of the 13th to the beginning of the 15th centuries. The sample consisted of 208 individuals with sufficiently preserved orbits: 82 subadults and 122 adults. CO was correlated with sex, age-at-death, and three skeletal indicators of biological health: linear enamel hypoplasia, periostitis, and adult femur length as a proxy value for stature. Siler's and Gompertz-Makeham's parametric models of mortality as well as χ2 statistics were used to evaluate these relationships. Almost one-third of all analyzed individuals had signs of CO, including approximately 60% of the subadults. There was a very strong relationship between the age-at-death and incidence of CO, i.e., individuals with the lesion were dying much younger. The frequency of CO among the sexes was not statistically significant. On the other hand, CO had a negative effect only on adult males, i.e., males who had the lesion died at a younger age. Furthermore, CO and linear enamel hypoplasia were positively related for subadults, whereas no significant relationships were found among adults of corresponding sex. Incidence of periostitis and adult stature were not related to CO.

Skeletal Material

Abstract Anthropological examinations were performed on skeletal material from four barrow necropolises located in the Yampil Region (Ukraine) and dated to the Eneolithic, Bronze Age and Iron Age. The purpose of the examinations was the determination of sex and age at death of individuals, reconstruction of their stature and assessment of their status of health. The examinations covered 61 individuals: 17 children and 44 adults. Their health status was assessed using four common indicators: linear enamel hypoplasia, cribra orbitalia, porotic hyperostosis and dental caries.

Long Term Impact

Paleopathological and paleoparasitological studies seek evidences to understand health and disease in past populations. These two approaches are often used independently despite the obvious importance of its complementary. This paper aims to explore the possible relation between a common indicator of childhood stress and infection by intestinal parasites. Thirty adult individuals from the Islamic necropolis of Santarém (9th-12th cent. AD) were macroscopically examined for linear enamel hypoplasia. Sediment from the pelvis and skull of each skeleton were observed under the optical microscope in search of helminth eggs. Hypoplasic defects were identified in 46.67% of the individuals, mostly on canines and incisors. Eggs from Ascaris lumbricoides and Trichuris trichiura were identified respectively in 4 and 2 individuals. The Fisher’s exact test was performed to analyze whether the individuals with evidences of stress in early childhood were more prone to helminth infections or death at younger ages. Although these variables were shown to be independent, this exploratory study highlights the contribution of combining paleopathological and paleoparasitological methods to address the long-term impact of the physiological stress exposure in early life on the immune system. Furthermore, variety of factors that could have influenced these results are discussed and interpreted in a biocultural perspective.

Abstract Linear enamel hypoplasia (LEH) is treated as a nonspecific indicator of stress, but even so, many authors consider it the most reliable tool stress in anthropological research. Its analysis allows the reconstruction of health related to the socio-economic status of the group. This study documents and interprets patterns of LEH in Żerniki Górne (Poland), a settlement which was functional in the Late Neolithic and the Early Bronze Age. We examined two successive cultures: the Corded Ware Culture (CWC; 3200-2300BC) and the Trzciniec Culture (TC; 1500-1300BC). In total, there were 1486 permanent teeth (124 adult individuals). The frequency of LEH in the examined cultures shows a small rising trend. In these series from Żernik Górne, males showed a higher occurrence of LEH (16.5%) than females (13.4%). The earliest LEH appeared at similar ages at about 2.0/2.2 years and the last LEH occurred at about 4.2 years of age in both cultures. However, it is worth noting that periods associated with physiological stress were more common but not very long (four months on average) in the CWC. Longer stress periods (nine months on average) were associated with the TC.

Linear Enamel Hypoplasia

Inspired by previous finds of filed, likely ornamental grooves on upper incisors of Swedish and Danish male Vikings, a Viking sample from Denmark (ca. AD 800–1050) was studied (M=69, F=45, 90=?). We found evidence of modifications that could be distinguished from normal wear and linear enamel hypoplasia. In 24 individuals single or multiple filed horizontal grooves occurred on labial surfaces of the central upper incisors and some lateral incisors (22/159 or 13.8 percent). All grooves were inconspicuous and shallow, and other unrelated worn labial facets were found. This occurrence is unlike the grooves in male Swedish Vikings. The variation observed, as well as experiments with iron files and whetstones, leads us to suggest that the Danish Viking grooves could be made intentionally but more often developed as a result of task activities.

Incremental Lines

Linear enamel hypoplasia (LEH) produces abnormal incremental lines or depressions in teeth enamel caused by a deficiency in the growth of calcified tissue. The depth and width of the LEH events can indicate the severity and duration of a stressful life event. LEH can be used to investigate developmental stress, as it will occur when the individual is unable to cope with environmental stressors during development, such as food shortage, pathological challenge or other stressful events. The LEH technique has been used by zoo-archaeologists to obtain information on early domestication and husbandry practices in ancient populations of pigs, where high levels of LEH have been found to correspond to birth and weaning. The objective of this work was to investigate if LEH was present in modern pigs and whether it could be used as a welfare indicator.
