Infrared spectroscopy of the dry residue of liquor crystallograms in various diseases

The article presents the results of an examination of the dry residue of liquor crystallograms (DRLC) using infrared spectroscopy technique. 36 spectrograms were studied. Elements of similarity and difference were revealed in the spectrograms of organic substance (antifreeze, sodium cyclamate and fatty tissue), of DRLC of the crystal-forming matter CuCl(2)x2H(2)0, of DRLC of a live person and cadaveric liquor (with no brain injury in respective case histories), of DRLC of liquor of live persons with a brain injury, of DRLC of liquor of persons who died of a brain injury and of persons who died of other causes.     

Forensic medical evaluation of harm severity inflicted to one's health by slight craniocerebral injuries in the remote period

A pressing problem is discussed: forensic medical evaluation of harm inflicted to health by slight craniocerebral injuries. Analysis of 2150 expert forensic medical and medico-social conclusions revealed serious organization and methodological errors in evaluation of harm inflicted to health by slight craniocerebral injuries. Approaches to improving the quality of such forensic medical expert evaluations are outlined.     

Crystallographic analysis of liquor for diagnosis and life-time evaluation of craniocerebral injury

Liquor specimens were examined by crystallography in 136 patients with craniocerebral injuries of different severity, hospitalized at the neuroinjury department of Kaliningrad Emergency Hospital and in 12 normal subjects in 1997-1998. The crystallograms were evaluated by a sum of signs, as a result of which specific patterns of colony growth in health and craniocerebral injury of different severity were obtained.     

Evaluation of disorders in the liquor circulation in craniocerebral trauma

The modern methods of complex examinations of the brain in craniocerebral trauma are addressed and the possibilities of the topographic-and-anatomic substantiation in the forensic-medical (expert) evaluation of traumatic lesions of liquor-circulation structural elements are elucidated in the paper. Morphometry data characterizing the dislocation manifestations are presented with respect to the dislocation intensity and severity.     

Expert evaluation of medical documentation data in estimating the severity of injuries

Analysis of false expert conclusions related to unjustified clinical diagnosis is given. Failure of critical attitude of medicolegal experts to X-ray and neurologic symptomatology data in posttraumatic period is stressed.     

Frequency and severity of injuries in correlation with the height of fall

The main aim of this study was to examine the correlation between the height of fall and the frequency, extensiveness, and type of injuries of certain body regions and organs. The specific objective was to determine characteristic injuries of the analyzed body regions in relation to the certain height of fall. The study included 660 cases of fatal falls from height (469 males and 191 females). Results support the hypothesis that the frequency and extent of the injured body regions and organs are related to the fall height. Head injuries are characteristic of the falls from heights up to 7 m and beyond 30 m. Brain injuries in high falls from heights beyond 30 m show an absence of contre coup contusions and macroscopically evident intracranial bleeding. The extensiveness of chest injuries is significantly statistically associated with fall height. In cases of high falls, the frequency of abdominal injuries is not significantly statistically related to the height of fall. Liver injuries are the most common abdominal injury and the critical height of fall at which the liver injury occurs is 15 m. Injuries of liver and spleen are concomitant in high falls from heights beyond 24 m, irrespective of the manner of impact. The height of fall over 15 m appears to be a reasonable boundary height beyond which the injuries of two or three body regions are generally associated.     

有限元方法在法医学颅脑损伤分析中的应用

有限元方法(finite element method,FEM)是一种与现代计算机技术相联系的计算应力分析方法,已逐渐被应用于生物力学领域仿真人体结构力学功能研究,尤其是在颅脑损伤研究中最为广泛和深入。本文综述了现有头部有限元模型的特点、材料属性的赋值以及颅脑损伤有限元模型在钝力击打、高坠、交通事故等鉴定中的应用情况,探讨FEM建模在法医学颅脑损伤预测中的优劣势及其应用价值。     

Difficulties in forensic medical evaluation of some forms of craniocerebral injury

Conclusions of 41 repeated expert evaluations of craniocerebral injuries within the framework of criminal and civil cases investigation are analyzed. Some aspects of clinical and forensic medical diagnosis of lethal and nonlethal injuries to the head, evaluation of the quality of medical care, and qualification of the severity of harm to health are discussed. Causes of typical expert errors and approaches to their prevention are shown.     

Peculiar approaches to the estimation of the severity of harm to health in children with non-fatal injuries

The medico-legal estimation of non-fatal injuries in the children and adolescents is presented. The data obtained have been used to develop and substantiate the algorithm of forensic medical expertise of such injuries. Scientifically sound criteria have been proposed to be used for the purpose of expert estimation of the severity of harm to health associated with non-fatal injuries taking into consideration their clinical manifestations. The procedures of forensic medical expertise for the estimation of the harm to health have been analysed with special reference to non-fatal injuries in children and adolescents. Main attention was given to the accompanying strategic, organizational, and methodological errors. The approaches to their prevention and correction are described.     

Diagnostic imaging in cases of suspected child abuse--focus craniocerebral trauma divergent guidelines and resulting problems

For the clinical diagnosis of non-accidental craniocerebral trauma in children there are different recommendations and guidelines, which are not completely consistent. Depending on the examiner, the focus may be on therapeutic relevance, minimization of the exposure to radiation or potential conclusions as to the course of events. Under certain circumstances it may be difficult for the responsible institution to deal with all three perspectives, as is shown by the presented case. From the authors' point of view it would be desirable to work out a common guideline taking into account paediatric radiological and medicolegal aspects.

Forensic medical evaluation of head injuries inflicted by blows with blunt objects

A statistical evaluation of injuries of head tissues inflicted by blows with human body parts and with blunt hard objects of communal use was carried out. Characteristic morphometrical and topographical features of injuries and factors essential for their severity are defined.     

The forensic evaluation of dental injuries in Istanbul, Turkey

When a person is wounded in Turkey, he first attends hospital for treatment. The hospital is responsible for a report describing his injuries and their treatment and prognosis. The patient is then scanned by a specialist in forensic medicine who provides a final official report. In that report the lesions, the prognosis (including whether the injuries are life threatening or not) and the projected days away from daily activity are shown. In this study 18,317 cases which were examined in the second and the third Specialization Board of the Council of Forensic Medicine during 1996 were analyzed. Among them 112 cases were dental injuries. Dental injuries are reviewed according to their sex, causation, detail of injury, and they are compared to other studies.
