Kaposi's sarcoma in an Eskimo

An Eskimo who had been treated for a nasopharyngeal carcinoma was subsequently found to have a rapidly progressive form of Kaposi''s sarcoma confirmed at biopsy. No objective response was obtained by irradiation treatment of isolated nodules. However, vinblastine sulfate arrested the progression of the disease. Because this neoplasm is most prevalent in tropical climates its presentation in an Eskimo is believed sufficiently unusual to warrant this report.     

Canadian Eskimo permanent tooth emergence timing

To identify the times of emergence of the permanent teeth of Canadian Eskimos (Inuit), 368 children and adolescents were examined. The presence or absence of all permanent teeth except the third molars was recorded and these data subjected to probit analysis. Female emergence times were advanced over males. Generally, the Inuit of both sexes showed statistically significant earlier emergence times than Montreal children, except for the incisors. The present results do not support hypotheses indicating that premature extraction of the deciduous teeth advances the emergence of their succedaneous counterparts. There is some indication the controls of deciduous tooth emergence continue to play some part in emergence of the permanent dentition, especially the first permanent teeth that emerge.     

Cerumen types in two Eskimo communities

Data on cerumen types were collected from two separate samples of Alaskan Eskimos. The observed frequency of the recessive dry allele further documents the existence of a genetic cline for earwax types in this region and world populations.     

Frontal sinus size in Eskimo populations

The frontal sinuses of 143 Eskimo skulls from two sites in the Hudson Bay region of Canada were examined radiographically. No between-site or sex differences were noted in the size of the sinuses. On average, the sinuses are small and often bilaterally absent. The Canadian samples have smaller sinuses than reported for Alaskan Eskimos or American Indian groups.     

The Aboriginal Eskimo Diet in Modern Perspective

The aboriginal diet of the Arctic Eskimo, which consisted mainly of land and sea mammals and fish, is analyzed with respect to its capacity to provide the nutrients now regarded as essential for nutritional health. It is concluded that, despite its remarkably restricted composition, the native diet is capable of furnishing all the essential nutritional elements when prepared and consumed according to traditional customs. However, its low carbohydrate and high protein content necessitated major metabolic adaptations in energy and nitrogen metabolism. Erosion of the traditional diet culture and life style has been accompanied by a decline in nutritional status. [Eskimo, diet, nutrition]     

Probable malignancy in a Sadlermiut Eskimo mandible

The mandible of a Sadlermiut Eskimo woman, age at death 28 to 30 years, displays numerous well-formed foramina concentrated bilaterally around the mental foramina. Differential diagnosis identifies this lesion with highest probability as a metastatic cancerous lesion; of less likelihood are sarcoma, hyperparathyroidism, hemangioma, and osteomyelitis. The specimen deserves attention because identification of malignancy in paleopathological material is uncommon and difficult, and because malignancies in aboriginal Eskimo populations are reputed to have been rare or absent.
