CT checklist and scoring system for the assessment of soft tissue preservation in human mummies: application to catacomb mummies from Palermo, Sicily.

In this study we applied the recently developed "Checklist and Scoring System for the Assessment of Soft Tissue Preservation in Human Mummies" to catacomb mummies from Palermo, Sicily. Data from twenty-three full-body computed tomography (CT) examinations were available. These consisted of seventeen adults and six children dating from the late 18th to the late 19th centuries AD. Seventeen of these mummies were anthropogenically mummified, and six spontaneously. Based on the checklist and scoring system, soft tissue preservation varied between both mummification groups, among mummies with the same type of mummification, and within individual mummies at different anatomical locations. Checkpoints of the main category "A. Soft Tissues of Head and Musculoskeletal System" were clearly more frequent than checkpoints of the main category "B. Organs and Organ Systems". Among the anthropogenic mummies, intra-arterial filling achieved the highest preservation status of organs and organ systems. Despite the small sample size, the statistical evaluation showed significant differences between mummification types, with the highest soft tissue preservation found in anthropogenic mummies. Application of the "Checklist" allowed a standardized assessment and documentation of the soft tissue preservation of these mummies. The "Scoring System" facilitated a comparison among mummification groups and mummies by means of numeric values.

"Modeling ancient Egyptian embalming": radiological assessment of experimentally mummified human tissue by CT and MRI.

OBJECTIVE: To assess changes in different tissues during the process of artificial mummification by natron using computed tomography (CT) and magnetic resonance imaging (MRI), and to translate the results to image interpretation in paleoradiological studies of ancient mummies. MATERIALS AND METHODS: A human lower limb (LL) was amputated from a female donor 24 h post-mortem and mummified by artificial natron (54 % NaCl, 16 % Na2SO4, 18 % Na2CO3 12 % NaHCO3) in ancient Egyptian style. The LL was kept in a fume hood at 16-25 °C and 30-75 % relative humidity. CT and MRI were performed at specific intervals with quantitative evaluation of Hounsfield units (HU) and signal intensities (SI). RESULTS: Evaluated tissues showed different HU and SI changes during the experimental mummification. All tissues revealed an overall but varying increase of HU in CT examinations. All tissues except for the compact bone revealed an overall but varying decrease of SI in the IR and T2-weighted sequences of the MRI. Typical findings included a distinct increase of HU in the cutis at the end of the study and a temporary increase of SI in the IR and T2-weighted sequences in all muscle groups. CONCLUSIONS: Radiological findings showed a regular, controlled and effective dehydration by the applied natron without detectable putrefaction. Evaluated tissues revealed different radiological changes during the experiment, which altogether led to preservation of the tissues without radiologically identifiable destruction. The cutis revealed radiological signs of direct interaction with the natron in the form of covering and possibly permeation.

Historical sources about diseases, death and embalming regarding the family of Jean Antoine Michel Agar, Minister of Finance of Gioacchino Murat.

Among the mummies preserved in the Basilica of San Domenico Maggiore in Naples, there are the bodies of the wife and three children of Jean Antoine Michel Agar, Minister of Finance of Naple's Kingdom during the Monarchy of Joachim Murat (1808-1815). Between 1983 and 1987 paleopathological analyses were performed; in particular, X-ray examination allowed investigation of the health status of the Agar family members and reconstruction of the embalming processes used to preserve the bodies. In addition, an analysis of the historical and archival documents was carried out, to formulate hypotheses about the causes of death, demonstrating how these sources could become important instruments to obtain diagnoses and pathological histories.

[Neurological paleopathology in the pre-Columbian cultures of the coast and the Andean plateau (I). Artificial cranial deformation]. / Paleopatologia neurologica en las culturas precolombinas de la costa y altiplano andino (I). Deformaciones craneales intencionales.

AIMS: The aim of this work was to study the cranial trepanations and deformations carried out by the ancient Paraca, Huari, Tiahuanaco and Inca cultures. To do so, we conducted a field study involving visits to archaeological remains and anthropological museums on the Andean plateau and the Peruvian coast. DEVELOPMENT: Cranial deformation was more common in the Andean regions and was performed by putting little pieces of wood or compressive bandages on newborn infants' heads in order to modify the growth axis of the cranial cavity. Cranial deformations were performed for aesthetic and magic religious reasons, but were also used as a means of ethnic or social identification, as a symbol of nobility or to distinguish the ruling classes. The immediate consequence of such deformation was the modification of the normal process by which the cranial sutures close. There is a significant correlation between the presence of posterior and lateral wormian bones, according to the degree of artificial deformation. The persistence of metopic suture and exostosis of the outer ear canal have been found in 5% of the skulls belonging to pre Columbine mummies. Other paleopathological findings include cranial fractures (7%), porotic hyperostosis (25% of children's skulls), spina bifida occulta, signs of spinal disk arthrosis and Pott's disease. CONCLUSIONS: Artificial cranial deformation was a very widespread practice in the Andean regions in pre Columbine times.
