A suspected case of hunting accident. Case report

Nowadays, the use of molecular biology in forensics has made it possible to identify human victim and sometimes even the circumstances under which the death occurred through. In our case, a corpse of a 50-years old man with a gunshot wound was found in the woods. The suspected murderer declared that it had been a hunting accident while he shot a wild boar. During the autopsy, a bullet (Borra-bullet Gualandi, 32 gr) was found in the abdomen of the victim. The authors investigated the presence of boar and victim blood both on the bullet, in order to substantiate the thesis of the hunting accident. Laboratory investigations underscored the presence of human cellular material on the bullet, which corresponds to profile of the victim and human and porcine ribosomal DNA. Through this investigation, the authors showed that it was a hunting accident, because the bullet passed through the body of the boar before hitting the victim

SUDDEN UNEXPLAINED JUVENILE DEATH AND THE ROLE OF MEDICOLEGAL INVESTIGATION: UPDATE ON MOLECULAR AUTOPSY

In the past few years, contributions of molecular biology assays to the investigation of sudden juvenile death have permitted to clarify some of the pathogenetic aspects of sud-den arrhythmic death, opening the way to preventive action on victims’ relatives. We reviewed literature on the genetics of sudden juvenile death, and on molecular biol-ogy assays performed on autoptic samples. Biological investigation permits the detection of genetic mutations underlying the suscep-tibility to sudden cardiac death of individuals with rare inherited forms of arrhythmia (Long QT Syndrome, Brugada Syndrome, Lev’s disease etc.) through the analysis of criti-cal sequences codifying for ion channel subunits (HERG, KvLQT1, MinK, Mirp1, SCN5A, KCNQ1, KCNH2, KCNE1, KCNE2).The main objective of post-mortem investigation in sudden juvenile death is the detection of treatable monogenic inherited disorders, in order to prevent further deaths among the relatives of the deceased patient

Il consenso informato per l'effettuazione del test per la diagnosi di infezione da HIV: Come comportarsi in caso di minori

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. The HIV antibody test is generally used to reveal the infection. In most European countries the test is voluntary; in Italy, implementation of the test is now regulated by Law 135/90. Art. 5 of the law states that the test is voluntary while informed consent is obligatory. However, nothing is stated concerning the child's consent. By contrast, other Italian laws (e.g., Law 194/78, Law 194/96 and DPR 309/90) establish that the physician should only accept the wishes of minors after first appraising the maturity of the child and his/her age. Physicians must inform the minor about testing risks, about the meaning of its result, and about the most important aspects of sexual education.. They may then decide to inform the parents if they feel that the child would be unable to take future decisions in the event of a positive HIV antibody test

SUSPECTED CHILD ABUSE: UNUSUAL DEATH IN WESTERN COUNTRY. SUICIDE OR HOMICIDE?

This case report describes a particular case of carbonized corpse, found in his burnt-out car in an isolated Palermo’s west suburban zone. The goal of this case report is to describe the shame and the social stigma related with suspicious of pedophilia and how it led a man to suicide by fire, considering that is an unusual way to die in western countrie

Death of a 23-year-old man from cardiac conduction system injury through a blunt chest impact after a car accident.

Cardiac contusion, usually caused by blunt chest trauma, has been recognized with increased frequency over the past decades. Traffic accidents are the most frequent causes of cardiac contusion resulting from a direct blow to the chest. Myocardial contusion is difficult to diagnose; the clinical presentation varies greatly, ranging from a lack of symptoms to cardiogenic shock and arrhythmia. Although death is rare, cardiac contusion can be fatal. The Authors report a case of death due to a cardiac conduction system injury from a blunt chest impact following a car accident. The autopsy showed no external signs of thoracic trauma, no evident rib or sternum fractures. A small subendocardial hemorrhage was found in the region of the atrioventricular node. Histological examination revealed an injury of the atrioventricular node and His' bundle. The cause of the death was attributed to the arrhythmia induced by contusion of the cardiac conduction system

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. Within KD, oral mucositis ? represented by diffuse mucous membrane erythema, lip and tongue reddening and lingual papillae hypertrophy with subsequent development of strawberry tongue ? can occur both in the acute stage of the disease (0-9 days), and in the convalescence stage (>25 days) as a consequence of the pharmacological treatment. KD vascular lesions are defined as systemic vasculitis instead of systemic arteritis. This study analyzed the anatomical-pathological substrata of oral mucositis in a baby affected by Kawasaki disease and suddenly deceased for cardiac tamponade caused by coronary aneurysm rupture (sudden cardiac death of a mechanical type)

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. Each patient underwent a full-body post-mortem CT scan, and then a traditional autopsy. Conclusion: To date, there are no autopsy findings pathognomonic of drowning. This study proves that virtopsy is a useful tool in the diagnosis of drowning in that it allows us to understand if the victim was alive or dead when he entered the water and if the cause of death was drowning. Results: All the cadavers showed fluid in the airways and patchy ground-glass opacities in the lung. Only one patient had no fluid in the digestive tract; this patient had a left parietal bone fracture with a large gap and other multiple bone fractures (nose, clavicle, first rib and patella). One of the three patients who had fluid in the digestive tract had no fluid in the paranasal sinuses. This latter patient showed cerebral oedema with subarachnoid and intraventricular haemorrhage, multiple bone fractures (orbital floor, ribs, sacrum and acetabular edge) and air in the heart, in the aorta and in bowel loops. © 2014, Italian Society of Medical Radiology
