Forensic medicine experts are well aware of blunt abdominal trauma, which often lead to death because of serious internal organ injury with severe blood loss. Sometimes careful examination of such cases may reveal some other underlying conditions, such as an existing disease that had contributed to the death or life-threatening complications. Our article presents a rare case of spontaneous hepatic rupture and intraperitoneal hemorrhage in a 32-year-old primigravida and her 29-week fetus, which was a result of hemolysis, elevated liver enzymes, and low platelet count syndrome. The said syndrome is a life-threatening obstetric complication usually considered to be a variant or complication of pre-eclampsia, which is characterized by hemolysis with microangiopathy, elevated liver enzymes, and low platelet count.
Cel pracy: Celem pracy jest ocena przydatności ciała szklistego oka (vitreous humour-VH) w oznaczaniu alkoholemii u zmarłych. W pracy przedstawiono korelację pomiędzy zawartością alkoholu etylowego w ciele szklistym a stężeniem alkoholu etylowego we krwi żylnej (femoral blood-FB). Materiał i metody: Materiał do badań stanowiły próbki krwi i ciała szklistego oka pobrane od 62 osób zmarłych w latach 2012-2016, których sekcje przeprowadzono w Zakładzie Medycyny Sądowej Uniwersytetu Medycznego w Białymstoku. Do badania zawartości alkoholu wykorzystano metodę chromatografii gazowej (GC). Uzyskane wyniki poddano analizie statystycznej przy użyciu programu MF Excel oraz Statistica 12.5, a następnie przedstawiono w formie opisowej oraz rycin i wykresów. Wyniki: Analiza statystyczna nie wykazała istotnych różnic pomiędzy stężeniem etanolu w VH i w FB. Korelacja Spear mana pomiędzy stężeniem etanolu w badanych materiałach wyniosła r = 0,96, p < 0,01. Wnioski: Przeprowadzone badania nie wykazały statystycznie istotnych różnic pomiędzy stężeniem alkoholu w VH i FB. Pozwala to przyjąć, że w przypadkach, gdy nie ma możliwości pobrania do badań toksykologicznych krwi żylnej, ciało szkliste oka może być stosowane jako wiarygodny materiał alternatywny.
The alternative light source (ALS) is a helpful technique for the detection of biological traces at a crime scene, which allows preservation of the material without destroying it. The aim of this study was to differentiate the human blood from a group of simulated bloodstains, which included: red borscht, raspberry juice, cherry liqueur, cranberry juice, tomato bruschetta, tomato paste, raspberry jam, rust, red spray, red wine and tomato ketchup. Stains, made of different types of material, were illuminated with the ALS emitted by the Mini-CrimeScope 400 (SPEX Forensics) with yellow, dark yellow, orange and red filters. The results of the analysis were presented as a description and also documented in photographs. The usage of light sources without color cut-off filters does not allow us to differentiate unequivocally real bloodstains from the trace evidence imitating or resembling bloodstains. The usage of different color cut-off filters (especially red filter) allowed us to exclude simulated bloodstains made of food and alcohol by using CSS light and light with a wavelength of 535 nm, 515 nm, 455 nm, 415 nm and 300-400 nm. Due to the different optical properties of blood and substances containing vegetable ingredients, forensic experts can differentiate human blood from simulated bloodstains by using the ALS in a non-destructive and quick way already at the crime scene. The ALS may be an example of a method which can replace more commonly used chemical-based screening tests.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
