Knowledge of Legal Terminology and Court Proceedings in Adults with Developmental Disabilities

This research compared 40 adults with mild developmental disabilities (DD) and 40 nondelayed adults (ND) in terms of knowledge of legal terms and court proceedings. For all of the 34 terms studied, with the exception of police officer there were significant differences between the DD and ND groups with respect to degree of conceptual understanding of terms. Results indicate that all but 6 terms assessed (adjourn, allegation, crown attorney, defendant, prosecute, and court reporter) were well-defined by 85% or more of ND participants. In contrast, only 8 of the terms (police officer, lawyer, jail, court, lie, truth, judge, and witness) were reasonably conceptually understood by at least 75% of DD participants. Reported familiarity with terms in DD participants is not a reliable indicator of actual familiarity with terms. Results are discussed with respect to the need for education of DD individuals and legal professionals to support participation and fair treatment of DD individuals in legal situations.     

Evaluation of the severity of harm to health by gastrointestinal injury caused by blunt trauma

A total of 226 forensic medical conclusions in traumas of the gastrointestinal tract with blunt objects, 111 of these with lethal outcomes, are analyzed. The types of injuries, clinical course, medical care, complications, flaws in medical care and their consequences, and pathomorphology of the injury were analyzed. Criteria of harm inflicted to health are determined and a table of qualifying signs is suggested for cases with blunt injuries of the gastrointestinal system, with consideration for the type of injury.     

Determination of heavy metals in some human organs, tissue, and fluids under normal conditions

A table has been created, presenting normal levels of heavy metals (Hg, Cd, Cr, Cu, Fe, Mn, Pb, Ni, Zn, Sn, Tl, Ag) in human biological media. In contrast to other handbooks, the authors use the normal values derived on the basis of their own investigations at the spectral laboratory of Bureau of Forensic Medical Expert Evaluations, Public Health Committee of Moscow and published reports. Comparative analysis was carried out for each element in human organs, tissues, and urine, which will facilitate expert work. Every laboratory engaged in expert evaluations and analysis in cases with suspected poisoning with heavy metal salts is to have reference values of these elements' concentrations in human organs and tissues obtained in this very laboratory on available equipment with consideration for specific features of its biogeochemical region.     

Hypophyseal damage in persons with cerebrocranial injuries and who died in the hospital

The pituitary was examined in patients with craniocerebral injuries who died in hospital in various periods after treatment. Control group consisted of victims died at the site of accident. The results indicate the significance of examining the pituitary in craniocerebral injuries for the diagnosis of thanatogenesis, particularly in patients died in hospital. Causes of traumatic changes in the organ were determined, highly incident in the practice of forensic medical experts: directly during injury, as a result of skull bone fractures; during development of dislocation syndrome and in disorders of blood and lymph circulation in the brain matter; resultant from augmenting traumatic edema of the brain.     

Forensic-medical diagnosis of heart damage from blunt trauma

A total of 277 forensic expert medical conclusions on cases with closed heart injury are analyzed. The morphology and mechanisms of formation of heart injuries in various traumas are discussed.     

Posttraumatic thrombosis of the middle cerebral artery

Posttraumatic cerebral infarction resulting from carotid or cerebral artery occlusion is rare. Traumatic dissection of the carotid artery is the most frequent cause of infarction, whereas posttraumatic thrombosis of the cerebral artery is very rare. The authors describe a case of posttraumatic thrombosis of the left middle cerebral artery. Early in the morning, a 16-year-old boy was found unconscious in the parking lot of a supermarket. He had received fist blows and kicks to the head, face, body, back, and hip during the night. Computed tomography 10 hours after the violence revealed a gross cerebral infarction in the area of the left middle cerebral artery. He died 9 days after the violence. The autopsy revealed a thrombosis in the left middle cerebral artery. Microscopically, granulation tissue in the intima and a rupture of the internal elastic lamina were observed near the beginning of the artery. It was concluded that the blows to the head and face caused a partial rupture in the arterial wall, leading to thrombosis and cerebral infarction.     

Piperazine-like compounds: a new group of designer drugs-of-abuse on the European market

1-Aryl-piperazine compounds are, depending on their substituents, selective for certain serotonin receptors and together with their easy availability and their so-called legal status, this group of psychoactive compounds are potential designer drugs-of-abuse. Internet in that respect is an important source of information and distribution facilities. Because this development may have consequences for the interpretation of future clinical and forensic toxicological case studies, some analytical aspects of 1-benzyl-piperazine (BZP), 1-[4-methoxyphenyl]-piperazine (pMeOPP) and 1-[3-trifluoromethylphenyl]-piperazine (TFMPP) were studied. BZP was not detected by the AxSYM FPIA technology designed to determine amphetamine-like compounds, but had showed some cross reactivity with EMIT d.a.u.. The cross reactivities at 300 and 12,000ng/ml (RS)-amphetamine equivalents were 0.4 and 1.3%, respectively. Although BZP was not identified directly by the REMEDi HS Drug Profiling System, it can be detected by this HPLC/UV scanning system. Using GC/NPD without derivatisation, BZP, pMeOPP and TFMPP can be analysed for and applying GC/MS without or with acetylation or trifluoroacetylation, these compounds can be identified unambiguously. The usefulness of GC/NPD and GC/MS in this respect was demonstrated by the quantitative and qualitative analysis of the content of a capsule with the synthetic stimulant A2, which proved to contain 86.4mg of BZP.
