The third most frequent agent of perinatal bacterial meningitis is Listeria monocytogenes , in Hungary, its occurrence is, however, uncommon. This raises the possibility of diagnostical mistakes. A connatal listeriosis case validated microbiologically referred to in this report calls attention to Listeria, as a rare but relevant pathogen of neonatal infections. If clinical background suggests infection, the pathogenic role of L. monocytogenes should be taken in consideration. The etiological significance of the agent has to be verified by a competent clinical microbiology laboratory, since maternal listeriosis should be treated and the serious connatal manifestations should be prevented. Epidemiology of perinatal infection by L. monocytogenes , and its diagnostic tools especially the use of selective media are discussed.

Abstract

In recent years, post mortem multi-slice computed tomography (MSCT) is increasingly applied for forensic and pathologic examination. However, classical dissection remains dominant in everyday practice. Lack of quantifiable data on the coronary system has become a disadvantageous attribute of traditional autopsy. Therefore, post mortem MSCT angiography was performed in 80 ex corpo hearts with the aim of improving the accuracy and quantitative documentation of pathologic and forensic diagnoses of coronary artery disease (CAD). Hearts were perfused by introducing a new oily or synthetic resin, or using both contrast materials successively. Then the perfused organs were processed for imaging. Detailed angiographic analysis enabled us to localize, map and quantify coronary calcifications, stenoses, and to characterize the types of atherosclerotic plaques. Significant early or late complications of widely used percutaneous coronary interventions (PCI) and coronary bypass surgery (CABS) could be revealed using CT analysis. Furthermore, by using our oily contrast material and CT imaging, we could identify and visualize the clinically important small caliber nodal arteries (diameter 0.4–2.0 mm). The present work suggests that post mortem CT angiography and post-processing of the data may improve the quality of pathologic and forensic diagnosis. Our collection of coronary casts including digital data are available for further analysis.
