Homicide with post mortem dismemberment of the victim with previous amputation of right lower limb: Case report and review of the literature.

The dismemberment of a corpse is comparatively rare in forensic medicine and usually performed with different types of sharp tools. The victim is always the victim of a homicide. Dismemberment usually occurs where the killing took place without prior planning by the perpetrator.

Determination of Propofol by GC/MS and Fast GC/MS-TOF in Two Cases of Poisoning.

Two cases of suspected acute and lethal intoxication caused by propofol were delivered by the judicial authority to the Department of Sciences for Health Promotion and Mother-Child Care in Palermo, Sicily. In the first case a female nurse was found in a hotel room, where she lived with her mother; four 10 mg/mL vials and two 20 mg/mL vials of propofol were found near the decedent along with syringes and needles. In the second case a male nurse was found in the operating room of a hospital, along with a used syringe.

A possible biomarker for methadone related deaths.

Unlabelled: Methadone (MTH) concentrations in those dying of MTH toxicity totally overlap concentrations where the presence of MTH is only an incidental finding, making it very difficult to make distinctions in actual cases. A biomarker, be it anatomical or biochemical for MTH toxicity is badly needed, particularly if that markers were known to disrupt effective ventilation. Because the brainstem houses the regulatory centers for cardiorespiratory-control enters, it would seem to be the most likely anatomical site to seek abnormalities in cardiorespiratory control.

Behavioural and pharmacological characterization of a novel cannabinomimetic adamantane-derived indole, APICA, and considerations on the possible misuse as a psychotropic spice abuse, in C57bl/6J mice.

The novel adamantane derivative APICA (N-(adamantan-1-yl)-1-pentyl-1H-indole-3-carboxamide) was recently identified as a cannabinomimetic indole of abuse. Despite its novel structure, APICA recalls cannabinomimetic indoles, such as representative member JWH-018. In present study, the effects of APICA (1-3mg/kg, i.

Role of virtopsy in the post-mortem diagnosis of drowning.

Purpose: Due to admitted limits of autopsy-based studies in the diagnosis of drowning, virtopsy is considered the new imaging horizon in these post-mortem studies. The aim of our study was to evaluate the role of virtopsy performed through computed tomography (CT) in the forensic diagnosis of drowning.

Materials And Methods: We retrospectively examined the CT data of four cadavers recovered from sea water and suspected to have died by drowning.

Unexpected variation of the codeine/morphine ratio following fatal heroin overdose.

Postmortem samples from 14 cases of suspected heroin overdose were subjected to a preliminary systematic toxicological analysis in order to highlight the presence of unknown exogenous compounds (e.g., drugs of abuse, alcohol) that may have played a role in the mechanism of death.

Legal aspects of sexually transmitted diseases: abuse, partner notification and prosecution.

Sexually transmitted diseases (STDs), with special emphasis to HIV infection, involve legal and ethical issues regarding informed consent to submit to a diagnostic, observance of professional secrecy in regard to partner(s) and community; legal troubles of particular difficulties are related to STD involving minors; lastly, physicians must be able to recognize the state of so called medical necessity. Knowledge and awareness of these related obligations are crucial to STD in medical practice; it is also important to allow for proper protection of victims of suspected sexual abuse under observation of healthcare. With regard to this aspect should be emphasized that violence against women and minors is a worldwide problem that has not yet been sufficiently acknowledged.

Detection of gamma-hydroxybutyrate in hair: validation of GC-MS and LC-MS/MS methods and application to a real case.

A gas chromatography-mass spectrometry (GC-MS) and a liquid chromatography tandem mass spectrometry (LC-MS/MS) method were validated for quantifying endogenous and exogenous hair concentrations of gamma-hydroxybutyrate (GHB). The GC-MS method is based on overnight extraction of 25 mg hair in NaOH at 56 °C, liquid/liquid extraction in ethylacetate and trimethylsylil derivatization; analysis is by electron ionization and single ion monitoring of three ions. The LC-MS/MS method entails a rapid digestion of 25 mg hair with NaOH at 75 °C for 40 min, liquid/liquid extraction in ethylacetate and reconstitution of the extract in the LC mobile phase; negative ion electrospray ionization and multiple reaction monitoring (MRM) analysis are employed for the LC-MS/MS detection.

Development and validation of a reliable method for studying the distribution pattern for opiates metabolites in brain.

Brain distribution pattern of "street" heroin metabolites (morphine and codeine) was investigated in two fatalities due to "acute narcotism". A suitable sample pretreatment prior to solid-phase-extraction was developed to achieve a good recovery of the analytes and to eliminate the interfering species. After derivatization with MSTFA, samples were analyzed by GC/MS.

A fatal case of a paint thinner ingestion: comparison between toxicological and histological findings.

Toluene and xylene are aromatic hydrocarbons commonly used as an industrial solvent for the manufacturing of pharmaceuticals, paints, and chemicals. The Occupational Safety and Health Administration has determined that toluene levels of 2000 parts per million (ppm) are considered dangerous to life and health. Several studies have examined the absorption of toluene and xylene following inhalation and oral ingestion in humans.

Lethal rupture of post-traumatic aneurysm of the vertebral artery case report.

Traumatic aneurysms or dissections of the vertebral artery have been reported in patients who have suffered minor craniofacial injuries in traffic accidents. A case is reported of ruptured traumatic vertebral artery aneurysm due to closed head injury without without penetrating injuries or skull fractures. The macroscopic and histological findings relevant to the vertebral wall were compatible with post-traumatic aneurysm; the rupture of the wall was assumed to be caused by sepsis and local infiltration of inflammatory cells.

Sudden death in adolescence caused by cardiac haemangioma.

Primary tumors of the heart in infants and children are rare. The types of heart tumors in pediatric age groups are generally different from those in adults. Cardiac myxoma is by far the most common tumor in adults, but in infants and adolescents the prevalent tumor of the heart is rhabdomyoma.

[Informed consent for HIV diagnostic tests: what to do in case of minors].

AIDS is a clinical picture related to Human Immunodeficiency Virus (HIV) infection. In the last 20 years this infection has spread progressively, with approximately 2.4 million children under 15 years old now infected.

Cervical necrotizing fasciitis and descending necrotizing mediastinitis in a patient affected by neglected peritonsillar abscess: a case of medical negligence.

We report a case of fatal cervical necrotizing fasciitis (CNF) and descending necrotizing mediastinitis (DNM) due to primary peritonsillar abscess in 60-year-old male patient with no history or evidence of immunocompromising disorders. The patient was treated with antibiotic and corticosteroid drugs but he developed mediastinitis and septic shock and died of multiple organ failure six days later from recovery in hospital. After a clinical, diagnostic and therapeutical consideration of the cervical necrotizing fasciitis and some related risks of a delayed diagnosis and treatment, the authors analysed the clinical history of the patient and of the medical conduct pointing out professional malpractice chargeable to doctors.

Post-traumatic lethal carotid-cavernous fistula.

The authors report about an unexpected death by traumatic lesion of the internal carotid artery in a 30-year-old man who had fallen two metres. The man suffered a fracture of the left maxillary sinus and a fracture of the right orbit with bilateral haemorrhage of the maxillary sinus. Surgical treatment was performed with favorable outcome.

Oral necrotizing microvasculitis in a patient affected by Kawasaki disease.

Kawasaki disease (KD) was first described in 1967 by Kawasaki, who defined it as "mucocutaneous lymph node syndrome". KD is an acute systemic vasculitis, which mainly involves medium calibre arteries; its origin is unknown, and it is observed in children under the age of 5, especially in their third year. The principal presentations of KD include fever, bilateral nonexudative conjunctivitis, erythema of the lips and oral mucosa, changes in the extremities, rash, and cervical lymphadenopathy.

Transmural coronary inflammation triggers simultaneous multivessel rupture of unstable plaques.

The authors describe a case of sudden cardiac death caused by the simultaneous multivessel rupture of unstable atherosclerotic plaques, triggered by a transmural inflammatory process (coronaritis). Male subject, 44 years old, apparently in good health until 1 hour before death, when he complained of worsening dyspnea. At autopsy, it was found that the heart weighed 486 g.

Typical homicide ritual of the Italian Mafia (incaprettamento).

Certain methods of homicide used by the Italian Mafia are intended to have an admonitory significance. One such method is the so-called "incaprettamento." This study analyzes 18 cases of homicidal ligature strangulation in which the body was found in this typical position.

Evaluation of pulmonary perfusion following an acute heroin overdose in dogs.

This research was designed to analyze the effects of heroin overdose on pulmonary perfusion in dogs. In view of this pulmonary perfusion by radionuclide method, arterial blood pressure by the femoral artery, mean right ventricular pressure and pulmonary wedge pressure by Swang-Ganz catheter were detected in 7 medium sized healthy dogs. In addition PaO2, SaO2, PaCO2 and blood pH were also determined by current methods.

[Anomalous origin of the right coronary from the left sinus of Valsalva. A possible cause of juvenile sudden death].

Anomalous origin of the right coronary artery from the left sinus of Valsalva is a rare congenital anomaly classified as a "minor" anomaly of no clinical importance. Recently, manifestations of myocardial ischemia (angina pectoris, myocardial infarction, nonfatal ventricular fibrillation, sudden death) have been described in patients with this anomaly in the absence of atherosclerosis or other. Sudden death occurs frequently in symptomatic patients and rarely in asymptomatic patients (sudden unexpected death).

Effect of heroin and morphine on cardiac performance in isolated and perfused rabbit heart: evaluation of cardiac haemodynamics, myocardial enzyme activity and ultrastructure features.

In the present study the effects of heroin and morphine administration on cardiac function, myocardial enzyme activity and cardiac ultrastructure features have been evaluated in isolated and perfused rabbit hearts. In 24 male rabbits the hearts were excised and immediately perfused in a retrograde non recirculating Langendorff apparatus. Successively, heroin 1 x 10(-5) or 1 x 10(-4) M or morphine at 1 x 10(-4) M were individually administered in 18 rabbits for 45 min.

[Right ventricular dysplasia and sudden death in young people].

In this study two autoptic cases of right ventricular dysplasia, observed in young and asymptomatic subjects who died suddenly are reported. In these patients, the "primary" myocardial atrophy involved the right ventricle, the right atrium and the conduction system: the sinoatrial node and the internodal pathways (in both cases) and the hisian bifurcation (only in the second case). The primary ventricular dysplasia was always associated with "secondary" transmural hyperplasia of the sub-epicardial fat tissue except for the anterior wall of the pulmonary infundibulum.
