Mephedrone is a β-ketoamphetamine belonging to the family of synthetic cathinones, an emerging class of designer drugs known for their hallucinogenic and psychostimulant properties as well as for their abuse potential. The aim of this review was to examine the emerging scientific literature on the possible mephedrone-induced neurotoxicity, yet not well defined due to the limited number of experimental studies, mainly carried on animal models. Relevant scientific articles were identified from international literature databases (Medline, Scopus, etc.) using the keywords: “Mephedrone”, “4-MMC,” “neurotoxicity,” “neuropharmacology”, “patents”, “monoamine transporters” and “neurochemical effects”. Of the 498 sources initially found, only 36 papers were suitable for the review. Neurotoxic effect of mephedrone on 5-HT and DA systems remains controversial. Although some studies in animal models reported no damage to DA nerve endings in the striatum and no significant changes in brain monoamine levels, some others suggested a rapid reduction in 5-HT and DA transporter function. Persistent serotonergic deficits were observed after binge like treatment in a warm environment and in both serotonergic and dopaminergic nerve endings at high ambient temperature. Oxidative stress cytotoxicity and an increase in frontal cortex lipid peroxidation were also reported. In vitro cytotoxic properties were also observed, suggesting that mephedrone may act as a reductant agent and can also determine changes in mitochondrial respiration. However, due to the differences in the design of the experiments, including temperature and animal model used, the results are difficult to compare. Further studies on toxicology and pharmacology of mephedrone are therefore necessary to establish an appropriate treatment for substance abuse and eventual consequences for public health.
Based on our findings, we propose that the Italian system might benefit from assertively adopting some concepts from the U.S. system. In particular, we consider the role of the law and Italian medicolegal experts as key facilitators for the integration of patient safety and risk management units within Italian healthcare facilities.
Photogrammetry is a technique that uses two-dimensional photographs taken from different angles and positions to determine three-dimensional coordinates and distances. Becoming familiar with the photography technique for photogrammetry purposes is the first step to obtaining high-quality results. Ten human cadavers were studied to develop this protocol. Appropriate equipment settings, measurements, and suitable ambient conditions were determined. Finally, the protocol was tested on one cadaver wherein a full postmortem examination was conducted, allowing accurate 3D modeling and measurements of the human body. This straightforward, step-by-step workflow will help users become familiar with this technique. A thorough description of the necessary steps is reported, including equipment, environment requirements, body placement, how to take photographs, and the minimum suggested number of photographs. Numerous graphics show the protocol's main steps to help users understand and reproduce the entire process. Photogrammetry allows the permanent recording and storage of photographic evidence of conditions that existed at the time of autopsy and accurate measurements of the body. The 3D model can have a powerful effect in court, where the findings can be accurately depicted without elicitation of strong emotion that may influence the judge or jurors. The primary disadvantage of photogrammetry for forensic pathology is its time-consuming nature. However, the widespread use of the photogrammetry technique in postmortem rooms would allow in-depth testing to detect and fix potential pitfalls, making this technique more reproducible and verifiable, increasing its admissibility in courts.
On 23 May 2013, the Italian health minister decided to endorse a law regarding controversial stem cell-based therapies in 32 young terminally ill patients, shocking many scientists. According to the international scientific community, these therapies could be dangerous because they were not rigorously tested in humans. This decision was made after many days of media and judiciary pressure. Several lawsuits regarding stem cell-based therapies were brought before the judiciary districts of different Italian regions. We analyzed the Italian legal context regarding the field of pharmaceutical and medical devices, including the European Union trend. A national database - commonly used to manage legal materials for professional or educational purposes or both - was used to find relevant legal cases involving stem cell-based therapies. Stem cell-based therapies endorsed by the new Italian law have been the subject of an important discussion not only in the scientific community but also in various courts. We found several legal actions filed by parents in order to make stem cells available to their young children, who had serious neurodegenerative diseases. The majority of the analyzed legal disputes were settled in favor of the applicants, whereas only two decisions (Courts of Justice of Rome and Florence) rejected the complaint because of the absence of sufficient scientific data regarding stem cell-based therapies. The present Italian situation is influencing the destiny of future young patients and strongly impacting public and institutional opinion. It is a practical example of the complexity of the decision of not providing unapproved scientific stem cell-based therapies when medicine does not have any other alternative therapies.
An 18-year-old female patient arrived at the emergency department complaining of abdominal pain and fullness after a heavy meal. Physical examination revealed she was filthy and cover in feces, and she experienced severe abdominal distension. She died in ED and a diagnostic autopsy examination was requested. At external examination, the pathologist observed a significant dilation of the anal sphincter and suspected sexual assault, thus alerting the Judicial Authority who assigned the case to our department for a forensic autopsy. During the autopsy, we observed anal orifice expansion without signs of violence; food was found in the pleural cavity. The stomach was hyper-distended and perforated at three different points as well as the diaphragm. The patient was suffering from anorexia nervosa with episodes of overeating followed by manual voiding of her feces from the anal cavity (thus explaining the anal dilatation). The forensic pathologists closed the case as an accidental death.
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.
