Computed tomography (CT) virtual autopsy and classical autopsy discrepancies: radiologist's error or a demonstration of post-mortem multi-detector computed tomography (MDCT) limitation?

Modern imaging technologies, such as computed tomography (CT) techniques, represent a great challenge in forensic pathology. The field of forensics has experienced a rapid increase in the use of these new techniques to support investigations on critical cases, as indicated by the implementation of CT scanning by different forensic institutions worldwide. Advances in CT imaging techniques over the past few decades have finally led some authors to propose that virtual autopsy, a radiological method applied to post-mortem analysis, is a reliable alternative to traditional autopsy, at least in certain cases. The authors investigate the occurrence and the causes of errors and mistakes in diagnostic imaging applied to virtual autopsy. A case of suicide by a gunshot wound was submitted to full-body CT scanning before autopsy. We compared the first examination of sectional images with the autopsy findings and found a preliminary misdiagnosis in detecting a peritoneal lesion by gunshot wound that was due to radiologist's error. Then we discuss a new emerging issue related to the risk of diagnostic failure in virtual autopsy due to radiologist's error that is similar to what occurs in clinical radiology practice.

Cicero, Tullia, and Marcus: Gender-Specific Concerns for Family Tradition?

A fair number of Cicero's letters reveal his concern for his daughter Tullia and his son Marcus. Recent scholarship has read these letters as evidence for a ‘natural’ emotional attachment of a father to his children, in reaction to Philippe Ariès's opposite claim. This chapter considers whether Cicero's letters can be analysed only as expressions of paternal affection. The fact that the pater familias Cicero occupies a political position simultaneously in his nuclear family, his domus, and the Senate, results in a concern for his prestige within the social field of the aristocracy. And this concern is necessarily conferred upon his support of the education and the social and political career of his children. The chapter traces the gender-specific differences between Cicero's treatment of Tullia and Marcus, shows the social construction of parental affection, and contributes to a further understanding of the different functions of daughters and sons in the social force field of family memory.

Contiguous ∼16 Mb 1p36 deletion: Dominant features of classical distal 1p36 monosomy with haplo-lethality

Monosomy 1p36 results from heterozygous deletions of the terminal short chromosome 1 arm, the most common terminal deletion in humans. The microdeletion is split in two usually non-overlapping and clinically distinct classical distal and proximal 1p36 monosomy syndromes. Using comparative genome hybridization, MLPA and qPCR we identified the largest contiguous ∼16 Mb terminal 1p36 deletion reported to date. It covers both distal and proximal regions, causes a neonatally lethal variant with virtually exclusive features of distal 1p36 monosomy, highlighting the key importance of the gene-rich distal region for the "compound" 1p36 phenotype and a threshold deletion-size effect for haplo-lethality.
