Systematic review of the toxicological and radiological features of body packing.

Body packing is the term used for the intracorporeal concealment of illicit drugs, mainly cocaine, heroin, methamphetamine, and cannabinoids. These drugs are produced in the form of packages and are swallowed or placed in various anatomical cavities and body orifices. Basing on these two ways of transportation a distinction between body stuffers and body pushers can be made, with the former described as drug users or street dealers who usually carry small amounts of drugs and the latter as professional drug couriers who carry greater amounts of drugs. A review of the literature regarding body packing is presented, with the aim to highlight the toxicological and radiological features related to this illegal practice. Raising awareness about the encountered mean body levels of the drugs and the typical imaging signs of the incorporated packages could be useful for clinicians and forensic pathologists to (a) identify possible unrecognized cases of body packing and (b) prevent the serious health consequences and deaths frequently occurring after the packages’ leakage or rupture or the packages’ mass obstructing the gastrointestinal lumen.

Drug-related deaths with evidences of body packing: Two case reports and medico-legal issues

Body packing is a general term used to indicate the internal transportation of drug packages, mainly cocaine, heroin, amphetamines, and methamphetamine, within the gastrointestinal tract. We described two cases of accidental drug intoxication, observed over the last year period, with evidence of intracorporeal drug concealment. The first case concerned a body packer transporting 69 drug packages of heroin adulterated with piracetam. The second body packer transported 16 drug packages of cocaine adulterated with levamisole. For both cases, forensic examination and toxicological analysis of drug packages and biological samples were carried out. Authors also wants to highlight the main medico-legal issues that commonly arise in cases of suspected or ascertained body packers.

Intrauterine fetal decapitation after a high-speed car crash.

Motor vehicle collisions are an important cause of blunt abdominal trauma in pregnant woman. Among the possible outcomes of blunt abdominal trauma, placental abruption, direct fetal trauma, and rupture of the gravid uterus are described. An interesting case of complete fetal decapitation with uterine rupture due to a high-velocity motor vehicle collision is described. The external examination of the fetus showed a disconnection between the cervical vertebrae C3 and C4. The autopsy examination showed hematic infiltration of the epicranic soft tissues, an overlap of the parietal bones, and a subarachnoid hemorrhage in the posterior part of interparietal area. Histological analysis was carried out showing a lack of epithelium and hemorrhages in the subcutaneous tissue, a hematic infiltration between the muscular fibers of the neck and between the collagen and deep muscular fibers of the tracheal wall. Specimens collected from the placenta and from the uterus showed a hematic infiltration with hypotrophy of the placental villi, fibrosis of the mesenchymal villi with ischemic phenomena of the membrane. The convergence of circumstantial data, autopsy results, and histological data led us to conclude that the neck lesion was vital and the cause of death was attributed to the motor vehicle collision.

Variability in findings of anogenital injury in consensual and non- consensual fisting intercourse: A systematic review

Fisting is an uncommon and potentially dangerous sexual practice. This is usually a homosexual activity, but can also be a heterosexual or an autoerotic practice. A systematic review of the forensic literature yielded 14 published studies from 8 countries between 1968 and 2016 that met the inclusion/exclusion criteria, illustrating that external anogenital (anal and/or genital) trauma due to fisting is observed in 22.2% and 88.8% (reported consensual and non-consensual intercourse, respectively) of the subjects, while internal injuries are observed in the totality of the patients. Establishing the reliability of the conclusions of these studies is difficult due to a lack of uniformity in methodology used to detect and define injuries. Taking this limit into account, the aim of this article is to give a description of the external and internal injuries subsequent to reported consensual and non-consensual fisting practice, and try to find a relation between this sexual practice, the morphology of the injuries, the correlation with the use of drugs, and the relationship with assailant, where possible. The findings reported in this paper could be useful, especially when concerns of sexual assault arise.

Fetal age determination through biparietal diameter: a simple method of cranial reconstruction using multipurpose silicone.

In forensic medicine, gestational age of fetal remains is a crucial information in several contests, but the classic methods are inadequate when early gestational age needs to be assessed. In the authors experience, the measurement of the biparietal diameter provides more accurate information for this purpose. The status of the fetal head is therefore critical. This work describes an easy technique that allows to reconstruct the cranial volume of the fetus using multipurpose silicone given both the flexibility of the fetal head structure and the inorganic nature of the silicone itself. In conclusion, the determination of the biparietal diameter achieved through the above‐described technique permitted a more accurate estimation of the dating of pregnancy in judicial cases where the fetal remains were incomplete and disrupted.

Weapon identification using antemortem CT with 3D reconstruction, is it always possible? - A report in a case of facial blunt and sharp injuries using an ashtray

An interesting case of homicide involving the use of a heavy glass ashtray is described. The victim, a 81-years-old woman, has survived for few days and died in hospital. The external examination of the victim showed extensive blunt and sharp facial injuries and defense injuries on both the hands. The autopsy examination showed numerous tears on the face, as well as multiple fractures of the facial bones. Computer tomography scan, with 3D reconstruction, performed in hospital before death, was used to identify the weapon used for the crime. In recent years new diagnostics tools such as computer tomography has been widely used, especially in cases involving sharp and blunt forces. Computer tomography has proven to be very valuable in analyzing fractures of the cranial teca for forensic purpose, in particular antemortem computer tomography with 3D reconstruction is becoming an important tool in the process of weapon identification, thanks to the possibility to identify and make comparison between the shape of the object used to commit the crime, the injury and the objects found during the investigations. No previous reports on the use of this technique, for the weapon identification process, in cases of isolated facial fractures were described. We report a case in which, despite the correct use of this technique, it was not possible for the forensic pathologist to identify the weapon used to commit the crime. Authors wants to highlight the limits encountered in the use of computer tomography with 3D reconstruction as a tool for weapon identification when facial fractures occurred.

Accidental death involving professional fireworks.

An interesting case of accidental death involving the explosion of professional fireworks in an apartment is described. The examination of the scene permitted to study several effects of the explosion on walls, ceiling, furniture and especially on a balcony where the victim was found. The external examination of the victim showed extensive thermal injuries, degloving injuries and extensive shrapnel wounds. The autopsy examination showed subarachnoid haemorrhage localized to the cerebellum, haemorrhage in the soft tissues of the neck and chest and fracture of one clavicle. Almost the entire surface of lungs showed blunt injuries and the liver showed tearing of parenchyma and multiple cavities. Histological analysis were carried out showing thickening of alveolar septae, enlargement of alveolar spaces and alveolar ruptures in lung sections while numerous, round, empty spaces were detected in the parenchyma of the liver. The examination of the scene and of the fragments found showed that at least eight pyrotechnical charges exploded on the balcony, in close proximity of the threshold with the living room of the apartment. According to the chemical findings, the charges were typical for professional use and were filled with a mixture of potassium perchlorate and aluminium. A conservative calculation results in more than 1.5 kg total mass of pyrotechnic composition exploding very close to the victim.

Time since death in a case of simultaneous demise due to a single gunshot: an issue concerning the use of Henssge’s nomogram

We report a case of a double homicide in which the victims, a man and his daughter, were simultaneously killed by a single gunshot. The temperature-based nomogram method for estimation of the time since death was used to ascertain the reliability of the method in a case of simultaneous demise, where the exact time of death was obtained from the analysis of security cameras.In the case presented, the victims differed for a great number of parameters (e.g., atmospheric conditions, thermal insulation of lower trunk, and, above all, body weight), except for the time of death, that was simultaneous. The correct application of the method permitted us to conclude that the estimated time since death was fully consistent with the circumstantial data obtained by the analysis of security cameras.No previous papers reporting the use of the nomogram method in a case of ascertained simultaneously death exists in literature; issues concerning the use of the nomogram method have been presented as well.

Fourth-Degree Perineal Laceration in Nonconsenual Fisting: A Case Report, Brief Review of the Literature, and Medicolegal Issues

Abstract We present the case of an 18-year-old girl who was sexually assaulted with transanal forearm penetration resulting in a fourth-degree perineal laceration. Fisting is an uncommon sexual practice consisting in the penetration of the vagina, anus, or both of them with fingers, hand (fist) or forearm. Perineal lacerations are a relatively common finding in both consensual and nonconsensual fisting victims. Even though cases of fisting with first-, second-, and third-degree lacerations have been reported in literature, only one previous case of fourth-degree perineal laceration has been described in a woman, who died after anal fisting. The clinical and morphological findings related to this sexual practice have been presented. No previous reports concerning nonfatal cases of fourth-degree perineal laceration, due to anal fisting, exists in literature. We report a case in which the forensic evaluation and the identification of the sexual assault were delayed because of both the atypical and uncommon pattern of injury and the unconsciousness of the patient. The information gathered thanks to this article would support forensic pathologists and sexual assault forensic examiners in recognizing doubtful cases, and this is particularly important when the suspect of sexual assault arise.

Mephedrone and Mephedrone-Based Cocktails: Market, Analysis, Mechanisms of Action, and Toxicity

Abstract In recent years mephedrone (4-methylmethcathinone) has gained popularity over other classified recreational drugs of abuse due to its low price and availability on the Internet. Because of its unwanted toxic and possibly lethal effects it is currently a matter of concern to public health worldwide. The significant qualitative and quantitative variation in content of the purportedly mephedrone-containing products on the market as well as the tendency to assume mephedrone combined with other drugs is challenging in terms of analytical identification in both street and biological samples. Furthermore, the many possible mephedrone-based combinations limit the possibilities of narrowing the clinical presentation of mephedrone intoxication, hence impairing the effectiveness of medical intervention. For these reasons awareness on the matter of mephedrone recreational use is necessary among clinicians and forensic scientists and, at least, the most common compounds derived from the combination of mephedrone and other substances should be included in toxicology screening procedures.
