Evidence of probable scurvy in subadults from archeological sites in North America.

The authors surveyed subadult human skeletons from Native American archeological sites in the United States for evidence of skeletal lesions associated with scurvy. Geographic regions surveyed include the Midatlantic area, the Southeast (Florida), the Southwest, and the Plains. The prevalence of probable subadult scurvy ranged from zero in the Plains samples to 38% in a small sample from Florida. These data indicate the likelihood that scurvy was a significant childhood disease in many Native American groups. Reasons for variation in prevalence remain speculative but include regional and seasonal variation in food types and abundance, cultural patterns of storage and utilization, periodic food shortages, and the relative importance of corn in the diet. These factors are part of a nutritional complex that is related to disease prevalence which can be studied through evidence seen in archeological human remains.

Brief communication: neurotraumatological aspects of head injuries resulting from sharp and blunt force in the early medieval period of southwestern Germany.

Approximately 10% (33 of 304) of the predominantly male skulls from the 6th through 8th centuries in southwestern Germany exhibit cranial fractures derived from blunt or sharp force trauma. No evidence of fracture healing characterizes 24% (n = 8) of these individuals. All nonhealed fractures were caused by sharp force, and four of these wounds cross the sagittal sinus. The lengths of these straight-edged wounds, produced exclusively by sword blows, measure around 8.0 cm for fatal, and about 5.0 cm for nonfatal wounds. Seventy-six percent (n = 25) of these skulls exhibit some healing, which indicates that these injuries did not lead to immediate death. In this group are all depressed fractures resulting from blunt force blows. Two thirds of the 45 cranial injuries noted on these 33 skulls are located on the left side of these individuals, with a concentration in the frontoparietal region. Bony indications of wound infection occur in four cases (12%). Three crania exhibit circular trepanations in association with fractures. These phenomena are discussed in the context of modern neurotraumatological knowledge.

Cribra orbitalia in the aborigines of Hawaii and Australia.

Cranii of 53 Hawaiian aboriginal infants and children, and 45 from Austrailian aboriginal children were inspected. Cribra orbitalia was present in 22.8% of the former and 26.6% of the latter; osteoporotic pitting (symmetrical osteoporosis; porotic hyperostosis) was also present in the latter. The frequency compares favorably with that found in pre-Columbian North American Pueblo Indians, 24.7%. It is associated with a widespread skeletal involvement suggestive of an active bone marrow. The findings support the concept that cribra orbitalia is related to symmetrical osteoporosis and that it may be associated with a blood disorder.

Cranial dysraphism mistaken for trephination.

Attention is called to a disputed diagnosis of trephination reported for a perforated skull of a prehistoric New England Indian. The perforation, surrounded by a saucer-like depression, is located exactly in the midline just in front of bregma. The finding of a similar lesion in a prehistoric Indian skull from the North Coast of Peru--where, as in New England, good evidence of the practice of trephination is lacking--provides support for a more reasonable diagnosis for both cases: congenital cranial dysraphism, specifically encephalocele. Information about dysraphic states from modern clinical experience is summarized.

Histological analysis of undecalcified thin sections of archeological bone.

Archeological bone often lends itself to histological analysis. Sections from bone samples approximately one thousand years old may show as much structural preservation as those only a few hundred years old; hence, it appears that the degree of preservation is not necessarily affected by time. Enough structure may be preserved to permit the diagnosis of metabolic disorders of bone which might go undetected by other methods. This type of analysis can be utilized to accept or reject individual remains suspected of being pathological on the basis of other less precise diagnostic techniques.

The etiology and porotic hyperostosis among the prehistoric and historic Anasazi Indians of Southwestern United States.

Porotic hyperostosis was studied in 539 crania from maize-growing prehistoric and historic groups who occupied two dissimilar ecological zones of the Plateau country of Arizona and New Mexico--canyon bottoms and sage plain. Defined as abnormal localized sieve-like structural changes involving the hematopoietic areas of the cranium, it was found in 185 (34.3%) of these skulls. More frequent in children than in adults, it shows significant frequency differences between both children and adults of the two ecological zones. The two ecological zones differ in the availability of iron in the diet; the canyon inhabitants depended heavily on maize (which interferes with iron absorption) while the sage plain people consumed more iron-rich animal products. We hypothesize that an increased dependence on maize produced more iron deficiency anemia and resulted in more porotic hyperostosis. Maize is known to have permitted a food surplus which in turn allowed for increased Southwestern population growth in marginal areas like the canyon bottoms. Heavy dependency on a single food type with consequent hematologic problems may have been an important reason for the subsequent abandonment of the Anasazi region.

The association between Harris lines and enamel hypoplasia in prehistoric California Indians.

Hypoplastic defects of tooth enamel and Harris lines in the long bones have been heralded as potentially useful indicators of health conditions in prehistoric populations. Both result from temporary cessation of growth processes due to similar types of disease, malnutrition, or other metabolic insult. An association test for the first six years of life was conducted on a large series of prehistoric California Indians, using femora and canines from young adults. No significant association was found. This is ascribable to differences in etiology and stability.
