“…The lack of detail in these studies’ descriptions make it difficult however to confirm the similarity in the fracture pattern. Moskała et al included an image of a ‘circular’ fracture in their study of PMCT in motorcyclists which shares the features in our cases; it is not further described, except to note that these types of fractures can be difficult to see on traditional autopsy [ 3 ]. A review of basal skull fractures in relation to helmet-use also described several fractures with features similar to our cases [ 13 ].…”

StreszczenieCel pracy: Problematyka zgonów osób z wnętrza samochodu w wyniku wypadków komunikacyjnych stanowi istotną grupę zagadnień w medycynie sądowej. Opiniowanie w tym zakresie obejmuje przede wszystkim określenie przyczyny zgonu oraz udział medyka sądowego w procesie rekonstrukcji przebiegu zdarzenia drogowego poprzez określenie mechanizmu powstania obrażeń ciała. Zakres opinii, jej dokładność i szczegółowość w dużym stopniu zależą od zakresu sądowo-lekarskiego badania pośmiertnego. W tym kontekście istotne są techniki zwiększające możliwości standardowej sekcji zwłok. W pracy przedstawiono wyniki pośmiertnego badania tomografią komputerową (post mortem computed tomography -PMCT) ofiar wypadków drogowych z wnętrza samochodu (kierowca, pasażer), które zestawiono z wynikami standardowej sekcji zwłok, określając zakres, w jakim badanie PMCT zwiększa w sposób istotny możliwości badania pośmiertnego. Materiał i metody: Analizie poddano 118 przypadków ofiar z wnętrza samochodu (kierowcy i pasażerowie), badanych w latach 2012-2014. Sekcja zwłok w każdym przypadku poprzedzona była badaniem PMCT przy użyciu aparatu Somatom Emotion 16 (Siemens AG, Niemcy). Wyniki: Wyniki badań zaprezentowano w formie tabelarycznej. Wnioski: Pośmiertne badanie tomografią komputerową w przypadku ofiar wypadków komunikacyjnych (kierowca -pasażer) ma istotne znaczenie dla zwiększenia szczegółowości wyników, zwłaszcza w zakresie obrażeń kostnych i przestrzeni gazowych.Słowa kluczowe: wypadki drogowe, medycyna sądowa, pośmiertna tomografia komputerowa. AbstractAim of the study: Deaths of in-vehicle victims (drivers and passengers) of road accidents represent a significant group of issues addressed by forensic medicine. Expressing opinions in this regard involves first of all the determination of the cause of death and the forensic pathologist's participation in the process of road accident reconstruction through defining the mechanism of bodily harm. The scope of the opinion as well as its accuracy and degree of detail largely depend on the scope of forensic autopsy. In this context, techniques that broaden the capabilities of standard autopsy are of particular importance.

“…Currently, transitional necropsy is considered as a gold standard and PMCT as an adjuvant method for investigation of the cause of death in both humans and animal. However, PMCT has been previously recognized as superior to the gold standard, in the detection of micro fractures and gas in the body cavities or vascular system [4]. Traditional methods to calculate sensitivity is these cases result in values greater than one, which is not a reasonable way to compare the two approaches.…”

This work proposes a novel approach to estimate the sensitivity of post-mortem computed tomography (PMCT) with respect to traditional necropsy (gold standard). Using concepts of Bayes theorem and the opinion of 57 veterinarians of how a relevant finding (RF) on PMCT or at necropsy can be a determinant in the animal's death, the general sensitivity was estimated. Such sensitivity can be interpreted as the probability to identify a specific RF in a necropsied animal. In the study, we included 18 animals that were subjected to traditional necropsy and underwent PMCT, which provided 48 different findings; all were assumed as a potential cause of death. This study aimed to understand the probability of death, given that a necropsied animal presented a specific RF. To estimate all contributions of the 48 RF, we designed a simple survey based on the Delphi method. In this survey, we invited veterinarians to evaluate the 48 NF and to assign a grade in a Likert scale from 0 to 10 for each of the RFs. In this scale, 0 (zero) indicates that the NF does not contribute to the animal's death, and 10 (ten) indicates that this NFdoes totally contributes to the animal's death. Therefore, each veterinarian, according to their own professional experience, assigns a grade describing how important each necroscopic finding is to the animal's death. Our results demonstrated that the problem of sensitivity analysis in the absence of a gold standard could be circumvented by the method proposed here.
