Hypervisor memory acquisition for ARM
2021
Abstract Cyber forensics use memory acquisition in advanced forensics and malware analysis. We propose a hypervisor based memory acquisition tool. Our implementation extends the volatility memory forensics framework by reducing the processor's consumption, solves the in-coherency problem in the memory snapshots and mitigates the pressure of the acquisition on the network and the disk. We provide benchmarks and evaluation.
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…
Unsolved questions and preferred solution about living will
2018
Abstract Background Ethical problems about end-of-life medicine include a variety of issues approached in different ways by physicians and, more recently, special emphasis to this kind of ethical issues and possible answers has done by Italian National Ethical Committee in the issue named “Deep and continuous palliative sedation in the imminence of Death” (January, 2016). The debate is very critical in Intensive Care Units and Cancer Wards, where health care professionals face-off with terminally-ill patients is an outright routine; the Authors investigated their medical knowledge and ethical perception about patient critical and terminal condition to discuss the most relevant conclusions. …
The medico-legal implications in medical malpractice claims during Covid-19 pandemic: Increase or trend reversal?
2020
The Covid-19 pandemic caused a marked increase in admissions to intensive care units. The critically ill patients’ condition from the infection resulted in their deaths. The healthcare facilities have got into trouble because of the pandemic. In fact, they had to create additional beds in a very short time and to protect health workers with personal protective equipment. Healthcare professionals fear that there will be an increase in complaints and medico-legal malpractice claims and hence they have urged politicians to discuss this. The Italian Parliament recently debated the topic of medical liability and passed the Decree-Law no. 18 of 17 March 2020 (DL – so called Cura Italia) by which…
A Pilot Study of Group Administered Metacognitive Training (MCT) for Schizophrenia Patients in a High-Security Forensic Setting: Subjective Training …
2015
Metacognitive group training (MCT) for psychosis has showed promising effects on positive symptoms of schizophrenia, even in forensic settings. Its effect on health-related quality of life (HRQOL) or patient perspective of it has not been studied before in violent inpatients. This pilot study investigated the patient perspective of the MCT, assessed the intervention’s effects on HRQOL compared with the control group, and compared the patients’ HRQOL with that of the general population. Twenty male violent inpatients with schizophrenia participated and were randomized to the eight-session MCT or to treatment as usual. The participants’ HRQOL was assessed at baseline, at posttreatment, and 3 …
Sensitive Screening of New Psychoactive Substances in Serum Using Liquid Chromatography-Quadrupole Time-of-Flight Mass Spectrometry.
2021
Abstract Analysis of new psychoactive substances (NPS) still poses a challenge for many institutions due to the number of available substances and the constantly changing drug market. Both new and well-known substances keep appearing and disappearing on the market, making it hard to adapt analytical methods in a timely manner. In this study we developed a qualitative screening approach for serum samples by means of liquid chromatography--quadrupole time-of-flight mass spectrometry. Samples were measured in data-dependent auto tandem mass spectrometry mode and identified by fragment spectra comparison, retention time and accurate mass. Approximately 500 NPS, including 195 synthetic cannabino…
Primary omental tumor with ultrastructural features of cellular schwannoma and absence of S-100 antigen reactivity.
1989
Summary We report a primary well-delimited, large mesenchymal omental neoplasm which appeared in a 58 year old man without neurofibromatous traces. The histological and ultrastructural features were consistent with a Schwann cell origin. However, repeated immunohistochemical reactions failed to demonstrate protein S-100 antigen reactivity in the neoplasic cells, the latter only expressing vimentin. The differential diagnosis with hemangiopericytoma is proposed.
Ultrastructure of vascular neoplasms
1982
Summary The vascular tumors are morphologically recognized by their ability to configurate complete or atypical angiomatous structures. Based on our personal experience of 42 cases of benign and malignant angiomatous tumors, we discussed several aspects of their histogenesis and its morphology when studied with transmission and scanning electron microscopy. Therefore, a survey of the normal histology was developed based not only on normal adult histological structures but also on reparative tissues, as in chronic inflammatory reactions of the gingival mucosa, regenerative tissue of wounds and in chronic osteomyelitis. Supported by morphological arguments, we postulate the existence of sever…
Extracranial metastasizing solitary fibrous tumors (SFT) of meninges: Histopathological features of a case with long-term follow-up
2012
Extrapleural solitary fibrous tumors are uncommon mesenchymal neoplasms frequently observed in middle-aged adults and are classified, according to the WHO classification of soft tissue tumors, as part of the hemangiopericytoma tumor group. However, these two entities remain separated in the WHO classification of tumors of the central nervous system. In fact, meningeal solitary fibrous tumors are believed to be benign lesion and only in a minority of cases local relapses have been described, although detailed survival clinical studies on solitary fibrous tumors of meninges are rare. In contrast to hemangiopericytoma, which frequently shows distant extracranial metastases, such an event is ex…
Chemistry in Crime Investigation: Sodium Percarbonate Effects on Bloodstains Detection
2011
Chemistry plays a leading role in crime investigation. In the study of bloodstains, chemical reactions provide the means for the detection. All these procedures have been thoroughly studied. However, recently, a new source of error has been found: washing stains with "active oxygen" detergents abrogates presumptive and human hemoglobin tests for bloodstains (although visible). The aim of this investigation was to evaluate the ability of pure sodium percarbonate-main component of detergents-to abrogate presumptive and human hemoglobin tests. Then, a solution to this problem could be found. The results demonstrate that pure sodium percarbonate-itself-is able to abrogate all tests, as well as …
