Background: Autologous facial fat grafting has gained popularity in recent years and is considered to be safe. This paper presents the case of a patient who died due to massive cerebral microfat embolism after facial fat grafting.

Objectives: The aim of this study was to raise awareness and provide more evidence on the prevention and treatment of this potentially lethal complication of facial fat grafting.

Post-mortem evaluation of drowning with whole body CT.

Purpose: The aim of this study is to investigate the value of whole body computed tomography (WB-CT) in bodies recovered from water by analysis of the imaging findings after drowning.

Methods: The bodies of 41 drowning victims and 9 persons who died from mechanical asphyxia by hanging underwent post-mortem whole body computed tomography.

Results And Conclusions: Excessive fluid in the paranasal sinuses (98%), nasal pharynx (98%), oropharynx (95%), trachea (83%), ground glass opacities in the lung (89%), pleural fluid (71%), pericardial fluid (59%), esophageal fluid (81%), stomach fluid and distension (71%), duodenal (34%) and jejunal distension (31%) were the most frequent drowning related imaging findings which significantly differed from the group of mechanical asphyxia by hanging.

Mice in ecstasy: advanced animal models in the study of MDMA.

The party drug 3,4-methylenedioxymethamphetamine -better known as MDMA or ecstasy- has numerous effects on the human body, characterized by a rush of energy, euphoria and empathy. However, also a multitude of toxic/neurotoxic effects have been ascribed to MDMA, based upon case reports and studies in animals. Given the intrinsic difficulties associated with controlled studies in human beings, most of our insights into the biology of MDMA have been gained through animal studies.

Post-mortem (re)distribution of 3,4-methylenedioxymethamphetamine (MDMA, "ecstasy"): human and animal data.

In this paper, the distribution and redistribution of the amphetamine derivative, 3,4-methylenedioxymethamphetamine (MDMA, ecstasy) is brought into focus. Animal experimental data were compared with internationally reported MDMA-related human fatalities: in general, these turned out to be parallel with each other. Due to its inherent properties (e.

Evaluation of the agonal stress: can immunohistochemical detection of ubiquitin in the locus coeruleus be useful?

The determination of the survival time after a crime as well as the concomitant physical and mental load of the victim is an important task for the forensic pathologist. The heat shock protein, ubiquitin, exerts an essential role in the cellular response to stress. We aimed to investigate the usefulness of the ubiquitin expression in the locus coeruleus as a marker for the evaluation of agonal stress.

Determination of antidepressants in human postmortem blood, brain tissue, and hair using gas chromatography-mass spectrometry.

A gas chromatographic-mass spectrometric (GC-MS) method in positive ion chemical ionization mode in combination with a solid phase extraction was optimized for new-generation antidepressants and their metabolites in postmortem blood, brain tissue, and hair. Twelve antidepressants and their active metabolites (i.e.

Hospital bed related fatalities: a review.

All medico-legal cases of unexpected death during hospitalisation or accommodation in rest or nursing homes, which were investigated at the Department of Forensic Medicine during a 30-year-period, have been reviewed. In the majority of cases, the fatal outcome was bedrail or restraint related, but falls out of bed or from a patient hoist lift can also trigger a death. As expected, the manner of death was mainly accidental.

Aconitine involvement in an unusual homicide case.

We describe a homicide complicated by an aconitine poisoning, which was initially thought to be a strangulation case. Routine toxicological analyses demonstrated only a small amount of alcohol in the blood and the urine. The case could not be clarified until 5 years after the event.

Postmortem distribution of 3,4-methylenedioxy-N,N-dimethyl-amphetamine (MDDM or MDDA) in a fatal MDMA overdose.

In this manuscript, a newly identified compound, 3,4-methylenedioxy-N,N-dimethylamphetamine (MDDM or also called MDDA), was quantified. The substance was identified in the biological specimens of a 31-year-old man who died following a massive 3,4-methylenedioxymethamphetamine (MDMA) overdose. In addition, the postmortem distribution of the identified substance in various body fluids and tissues was evaluated.

Amphetamines as potential inducers of fatalities: a review in the district of Ghent from 1976-2004.

Abuse of amphetamine (AMP) and its derivatives, such as 3,4-methylenedioxymethamphetamine (MDMA, 'Ecstasy'), 3,4-methylenedioxyethylamphetamine (MDEA, MDE), and 3,4-methylenedioxyamphetamine (MDA) is an important public issue. Fatalities following ingestion of these substances are not infrequent in current forensic practice. The aim of this study was twofold.

Drowning: still a difficult autopsy diagnosis.

Investigation of bodies recovered out of water comprises an important proportion of the medico-legal requests. However, the key question whether the victim died due to "true" drowning can frequently not easily be solved. In addition, the diagnosis of hydrocution is even more difficult.

Interpretation of a 3,4-methylenedioxymethamphetamine (MDMA) blood level: discussion by means of a distribution study in two fatalities.

The amphetamine derivative 3,4-methylenedioxymethamphetamine (MDMA, "Ecstasy" is a currently used or abused designer drug and fatalities are frequently encountered in forensic practice. However, the question remains open whether an MDMA blood level can be toxic or even potentially lethal. In order to provide insight in the interpretation of a detected MDMA concentration, the distribution of MDMA and its metabolite 3,4-methylenedioxyamphetamine (MDA) in various body fluids and tissues was studied and discussed in two different fatalities.

Tissue distribution of trichloroethylene in a case of accidental acute intoxication by inhalation.

This article describes the toxicological findings in a fatality due to an accidental inhalation of trichloroethylene which took place during wall coating of a poorly ventilated well using trichloroethylene. The man was wearing protective clothing and a mouthmask with adsorbent. He was found dead on the floor of the well 5h after descending.

Immunohistochemical demonstration of the amphetamine derivatives 3,4-methylenedioxymethamphetamine (MDMA) and 3,4-methylenedioxyamphetamine (MDA) in human post-mortem brain tissues and the pituitary gland.

Abuse of amphetamine derivatives such as 3,4-methylenedioxymethamphetamine (MDMA) and 3,4-methylenedioxyamphetamine (MDA) is an important issue in current forensic practice and fatalities are not infrequent. Therefore, we investigated an immunohistochemical method to detect the amphetamine analogues MDMA and MDA in human tissues. For the staining procedure, the Catalysed Signal Amplification (CSA) method using peroxidase (HRP) provided by Dako and specific monoclonal antibodies were used.

Post-mortem redistribution of 3,4-methylenedioxymethamphetamine (MDMA, "ecstasy") in the rabbit. Part II: post-mortem infusion in trachea or stomach.

Drug concentrations in autopsy samples can also be influenced by post-mortem gastric diffusion when the stomach contains a substantial amount of the drug or by diffusion from the trachea when agonal aspiration or post-mortem regurgitation of vomit occurs. This was studied in a rabbit animal model in which MDMA solutions were infused post mortem either in the trachea or in the stomach. At 24, 48 or 72 h post mortem, samples including cardiac blood, vitreous humour, urine, bile, gastric content and several tissues were taken for toxicological analysis.

Post-mortem redistribution of 3,4-methylenedioxymethamphetamine (MDMA, "ecstasy") in the rabbit. Part I: experimental approach after in vivo intravenous infusion.

Post-mortem redistribution is known to influence blood and tissue levels of various drugs. An animal model was used in an attempt to elucidate this problem for the amphetamine analogue, 3,4-methylenedioxymethamphetamine (MDMA). Rabbits received 1 mg/kg MDMA intravenously (iv) and were killed 2 h later in order to simulate the state of complete distribution in the body.

An inherited metabolic disorder presenting as ethylene glycol intoxication in a young adult.

Despite the abundance of reports emerging in the literature on metabolic disorders, some disorders remain undiagnosed or misdiagnosed, not only in clinical pathology but also in forensic pathology. The authors report a patient who had recurrent episodes characterized by nausea, vomiting, and signs of dehydration necessitating admission to the hospital. At each admission, he was found to have lactic acidosis.

Distribution study of 3,4-methylenedioxymethamphetamine and 3,4-methylenedioxyamphetamine in a fatal overdose.

In this study, regional tissue distributions of the amphetamine analogue 3,4-methylenedioxymethamphetamine (MDMA, "ecstasy") and its metabolite 3,4-methylenedioxyamphetamine (MDA) in a fatal overdose are presented. Quantitation of MDMA and MDA levels occurred in blood samples taken centrally (right and left heart and main adjacent great vessels) and peripherally (subclavian and femoral blood). In addition, MDMA and MDA concentrations were determined in cardiac and iliopsoas muscle, both lungs, liver, both kidneys, spleen, the four brain lobes, cerebellum and brainstem, and adipose tissue.
