Brain calcification in a case of acute lymphoblastic leukaemia

Cortical calcifications, seen on X-ray in the brain of a child suffering from leukaemia, were submitted to morphological and chemical analysis. The morphology was studied by a combination of low temperature ashing and microscanning. The calcification principally affected axons and capillary walls and consisted of spherules amalgamated into hollow cylinders. The results of chemical analysis of the calcified material were compared to those obtained in a case of Fahr's disease. The mineral composition and structure of both types of calcification were similar, but the Mn concentration was higher in the case of Fahr's disease. X-ray diffraction showed that the calcification consisted of amorphous calcium phosphate and acid calcium orthophosphate, most probably precursors of hydroxyapatite. © 1975.SCOPUS: ar.jinfo:eu-repo/semantics/publishe

Criteria for age estimation in living individuals

This paper presents updated recommendations of the Study Group on Forensic Age Diagnostics for age estimations in living individuals in criminal proceedings. In order to increase the diagnostic accuracy and to improve the identification of age-relevant developmental disorders, a physical examination, an X-ray examination of the left hand, as well as a dental examination including the determination of the dental status and an X-ray of the dentition should be performed in each case. If the skeletal development of the hand is completed, an additional radiological examination of the clavicles should be carried out. Minimum requirements for reference studies are defined and recommendable studies are listed. Instructions for the examination and the preparation of expert reports are presented. The committee of the study group organizes annual proficiency tests for quality assurance
