TL;DR: The results suggest that altitude confers allometric growth changes which are acquired during development while shape changes may be under genetic control, suggesting other concomitants confounding the effects of hypoxia in Andean South America.
Abstract: In 1972 a multidisciplinary study sought to assess the health status of the indigenous peoples of the Department of Arica in northern Chile, the Aymara, and to relate disease, morphological, physiological and biochemical variation, to the wide changes in altitude of the region. Presented here are the morphological changes which accompany age, altitude and ethnicity amoung 1047 children and adults, permanent residents of the coast, sierra and altiplano. At comparable ages, high-altitude residents were shorter, lighter and leaner but with more expansive and rounder chests than sea-level controls. None of these effects was systematically related to ethnicity (Spanish-Aymara surname), although when stature was held constant, children with greater Aymara ancestry had largest chest circumferences and longer bones. These results suggest that (1) altitude confers allometric growth changes (expensive growth of the chest and diminished growth of the structures less related to oxygen transport); and (2) size changes associated with altitude are acquired during development while shape changes may be under genetic control. Altitude appears to account for less of the variation in growth in this relatively homogeneous Chilean sample than has been reported for other Andean samples, suggesting other concomitants confounding the effects of hypoxia in Andean South America.

TL;DR: The authors present datos de valor demografico de empadronamientos ineditos de tributarios that van desde 1752 a 1804, a pesar de sus irregularidades, se busca una explicación en el patron de poblamiento o en sus caracteristicas culturales, utilizando las fuentes senaladas e informacion adicional contemporanea or posterior a estas visitsitas.
Abstract: Se presentan y discuten datos de valor demografico de algunos empadronamientos ineditos de tributarios que van desde 1752 a 1804. A pesar de sus irregularidades, se busca una explicacion en el patron de poblamiento o en sus caracteristicas culturales, utilizando las fuentes senaladas e informacion adicional contemporanea o posterior a estas visitas. Se encuentran claras referencias de que la poblacion atacamena muestra durante varios siglos patrones tanto de trashumancia como de control simultaneo de recursos apartados, estrategia que Murra ha llamado “verticalidad”. Su presencia en Atacama relativiza los datos demograficos en cuestion, no pudiendose determinar con precision que poblacion que se consideraba a si misma atacamena vivia en esa provincia colonial y cuanta vivia fuera de ella.

TL;DR: Two cases of gallbladder disease found in Chilean mummies are presented and the cholesterol gallstones in these cases produced in one individual a localized peritonitis and in the other a probable duct obstruction.
Abstract: Two cases of gallbladder disease found in Chilean mummies are presented. The cholesterol gallstones in these cases produced in one individual a localized peritonitis and in the other a probable duct obstruction. No cases of this disease have been seen in Peruvian mummies while in Chile it seems quite common, suggesting some environmental factor in the etiology.

TL;DR: This is the second case of a diaphragmatic hernia from 200 autopsies of mummies of Atacamena Indians found in northern Chile noted in an individual who died in the third century A.D. as a result of strangulation of two loops of the jejunum that entered the thoracic cavity.
Abstract: This is the second case of a diaphragmatic herniafrom 200 autopsies of mummies of Atacamena Indians found in northern Chile. This case is noted in an individual who died in the third century A.D. as a result of strangulation of two loops of the jejunum that entered the thoracic cavity. The herniation was probably congenital in nature.
