Macrophage-Specific Lipid-Based Nanoparticles Improve Cardiac Magnetic Resonance Detection and Characterization of Human Atherosclerosis

2009

ObjectivesWe sought to determine whether gadolinium (Gd)-containing lipid-based nanoparticles (NPs) targeting the macrophage scavenger receptor-B (CD36) improve cardiac magnetic resonance (CMR) detection and characterization of human atherosclerosis.BackgroundGd-containing lipid-based NPs targeting macrophages have improved MR detection of murine atherosclerosis.MethodsGadolinium-containing untargeted NPs, anti-CD36 NPs, and nonspecific Fc-NPs were created. Macrophages were incubated with fluorescent targeted and nontargeted NPs to determine uptake via confocal microscopy and inductively coupled plasma mass spectroscopy (ICP-MS) quantified Gd uptake. Human aortic specimens were harvested at…

Severe neonatal onset of glycogenosis type IV: Clinical and laboratory findings leading to diagnosis in two siblings

2005

Glycogenosis type IV is an autosomal recessive disease, exceptionally diagnosed at birth: only very few reports of the fatal perinatal neuromuscular form have been described. We report on two sibling male newborns who died at 10 and 4 weeks of age with clinical signs of a systemic storage disease. Prenatal history included polyhydramnios, reduced fetal movements and fetal hydrops, and Caesarean section was performed at 36 weeks of gestational age because of fetal distress. At birth, both babies showed severe hypotonia, hyporeflexia and no spontaneous breathing activity. They never showed active movements, sucking and swallowing and were respirator-dependent until death. A muscle biopsy reve…

Pitfalls on Postmortem Imaging: The Need of Blending Conventional and Virtual Autopsy on Burnt-Charred Body

2019

Joining forensic traditional autopsy and CT-MR postmortem virtual approach may assist forensic experts in adequate reconstruction of cause, manner, and way of death, significantly to find evidence of found wound/fracture and relative interpretation. Evaluation of criminal burning is often a difficult challenge in the view of misinterpretation of wound/fracture victims and usually poor case history of this criminal offense. In this scenario, a strong collaboration between imaging and classical forensic techniques is helpful.

Pharmacogenetics and Forensic Toxicology: A New Step towards a Multidisciplinary Approach

2021

Pharmacogenetics analyzes the individual behavior of DNA genes after the administration of a drug. Pharmacogenetic research has been implemented in recent years thanks to the improvement in genome sequencing techniques and molecular genetics. In addition to medical purposes, pharmacogenetics can constitute an important tool for clarifying the interpretation of toxicological data in post-mortem examinations, sometimes crucial for determining the cause and modality of death. The purpose of this systematic literature review is not only to raise awareness among the forensic community concerning pharmacogenetics, but also to provide a workflow for forensic toxicologists to follow in cases of unk…

Changes to legal forensic inspections in Sicily during Covid-19

2020

Our institute, in collaboration with the Public Prosecutor’s Office, arranges for cadaveric inspections during a judicial inspection, jointly with the police. With the advent of the Covid-19 pandemic, operating methods have changed. Specifically, we now discuss the cases individually before attending to guarantee the health of operators and citizens

Preventable fatal injury during rally race: a multidisciplinary approach

2020

Abstract Introduction The motor vehicle crash (MVC) constitutes an important challenge for forensic pathology in order to identify the manner and cause of death. Our study focuses on a fatal accident during a rally race corresponding to MVC sub-category. Materials and method Postmortem computed tomography (PMCT) was performed before the conventional autopsy. Autoptic and PMCT data were compared. Data collection allowed analyzing biomechanical dynamics of the incident and post-traumatic injuries through qualitative-statistics and solicitation quantitative indices. Results Photo and circumstantial evidence analysis showed a wrong installation of double shoulder belt system of head and neck su…

2017

Abstract Background The burden of cardiovascular diseases (CVDs) remains unclear in many regions of the world. Objectives The GBD (Global Burden of Disease) 2015 study integrated data on disease incidence, prevalence, and mortality to produce consistent, up-to-date estimates for cardiovascular burden. Methods CVD mortality was estimated from vital registration and verbal autopsy data. CVD prevalence was estimated using modeling software and data from health surveys, prospective cohorts, health system administrative data, and registries. Years lived with disability (YLD) were estimated by multiplying prevalence by disability weights. Years of life lost (YLL) were estimated by multiplying age…

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

2014

Abstract 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 sub-endoc…

Progressive calcifications of lung and liver in neonatal herpes simplex virus infection

1991

We report a female neonate who developed severe septicemia presenting with pneumonia and hepatitis due to an infection with herpes simplex virus type II. In spite of antiviral as well as intensive care therapy, three weeks after admission, extensive hepatic calcification was demonstrable on abdominal radiograph, a sign of severe cellular necrosis. In contrast the pulmonary infiltration recovered completely. The clinical follow up was completed by ultrasound and radiography. The infant died at the age of two months secondary to severe postnecrotic hepatic failure. At autopsy, histological evaluation confirmed the former diagnostic and technical findings; in addition, pulmonary calcifications…

Early calcification patterns of the iliac arteries and their relation to the arterial structure

1972

Gross calcifications of the common iliac and internal iliac arteries represent a common finding in newborn children and infants. In both arteries, the calcific deposits regularly appear in certain areas of the arterial luminal surface only, whereas the other parts of the arterial wall remain free of gross lesions even in cases with a pronounced calcification. In the common iliac artery, the lateral wall of the vessel and the adjacent sectors of the anterior and posterior wall represent the predilection site of calcific deposits. In the internal iliac artery, the gross calcifications have been regularly demonstrated in the dorso-medial wall. The predominant localisation of the calcification …
