A Probable Case of Acute Childhood Leukemia: Skeletal Involvement,Differential Diagnosis,and the Bioarchaeology of Cancer in South America

Cancer involves a complex spectrum of disease conditions. However, cancer has received relatively limited attention in paleopathology and bioarchaeology as it is infrequently encountered in the skeletal record, and its differential diagnosis in dry bone remains challenging. Of all neoplastic disorders, one of the most infrequently described forms in ancient skeletons is leukemia, or the myeloproliferative neoplasms of the reticuloendothelial system affecting bone marrow and blood. This case study describes and interprets a suite of lytic and proliferative lesions in the skeletal remains of an Early/Middle Colonial‐era child (ca. A.D. 1533–1620) excavated at the ruins of Eten, southwestern Lambayeque Valley Complex (north coast of Peru). A secondary burial contained the incomplete postcranial remains of a 5–6 year‐old child whose bones were characterized by abnormal porous loci in the right clavicle, scapulae, long bones of the upper limb, ribs, and thoracic and lumbar vertebrae. Additionally, fine areas of new bone formation were present on the clavicle and ribs. Multiple pathological conditions were evaluated in a differential diagnosis, including taphonomic changes and various bone resorbing and forming disorders. The lesions are most consistent with acute childhood leukemia and represent the first of its kind described in Andean South America. The identification of this condition helps focus research questions involving the bioarchaeology of cancer in the Andes, especially regarding the significance of neoplastic disorders in relation to the broader reconstruction of past human health in Peru.

Wissenschaftliche Photographie als visuelle Kultur. Die Erforschung und Dokumentation von Spektren

This paper discusses facets of 19th‐century scientific photography as a visual culture. The example of spectral research and documentation is particularly well suited, because prismatically diffracted light from the sun or from luminous gases was one of the most frequently examined phenomena of that century. The results were significant not only for physics but also for analytical chemistry and astrophysics. The spectrum also served as an ideal test object for checking the effectiveness of a wide array of photochemically sensitizable surfaces to the various color regions. Scientific photography became the most important experimental technique in the infrared and ultraviolet. H. A. Rowland's spectrum charts are discussed as an example of the transition from comprehensiveness in documentation to fetishism. The discussion of the Lippmann process, one of the first methods of color photography, addresses the associated training of the eye. Issues of authenticity and the much averred ?mechanical objectivity”? are raised with regard to retouching. The overriding theme of visual science cultures leads furthermore to unanticipated interdependencies with other scientific fields, such as geography, and draws the importance of practitioners into the foreground.
