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.

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.     

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.     

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.

实验性脑挫伤后caspase—1表达的研究

目的阐明不同程度及不同时间脑挫伤后caspase-1表达的变化。方法应用免疫组织化学染色、Western-blotting和RT-PCR方法对48例实验性脑挫伤大鼠的脑组织进行了检验,同时以3例非脑挫伤和3例假手术的脑组织做对照。结果脑挫伤后1h caspase-1即有表达,24-48h达高峰,挫伤后两周caspase-1阳性细胞仍维持较高水平。阳性细胞多集中于挫伤区及周围带皮质和脑实质内海马区,不同程度脑挫伤各组之间阳性细胞面积存在差异;损伤组caspase-1酶原裂解增加;损伤组caspase-1mRNA表达量明显高于对照组;不同程度脑挫伤组之间于各个时间段caspase-1mRNA表达未见差异。 结论 Caspase-1表达增加,可辅助诊断1h-14d的脑挫伤,并可根据caspase-1阳性细胞面积的变化来确定脑挫伤程度,同时对判断挫伤时间方面也有一定的价值。caspase-1参与脑挫伤后的神经细胞凋亡。

Forensic medical assessment of acute blood loss in combination with craniocerebral trauma and alcohol intoxication

Forensic medical findings have been analysed retrospectively for 242 deceased of acute blood loss: 186 (76.8%) corpses were male and 56 (23.2%) corpses were female. It was found that in acute blood loss (ABL) duration of the terminal period (TP) depended on its combination with craniocerebral trauma (CCT) or alcohol intoxication (AI). A short TP (several minutes) was observed in ABL patients with CCT (39.6%), a long-term TP--in ABL associated with AI (20-60 min, 40.4% cases; several hours, 56.3%; over 24 hours, 54.5%). Slow TP occurred primarily in mild AI (TP for several hours 55.6%, over 24 hours--83.3% cases). In severe AI the number of cases with a short TP exceeded the number of cases with a long TP (over 24 hours) by 53.7%.

Age-specific peculiarities of manifestations of a craniocerebral injury in children and adolescents with a combined blunt trauma

This study was designed to estimate the frequency of head injuries and selected manifestations of craniocerebral traumas in children and adolescents with a fatal combined blunt trauma. It is included 289 cases of death from a combined blunt trauma (101 original observations and data of 188 archival documents). The victims were categorized into 3 age groups. One group was comprised of cases from 0 to 3 years of life, group 2 included children aged from 4 to 11 years, and group 3 those at the age from 12 to 18 years. The age was shown to significantly influence both the frequency of head injuries and their severity. The maximum values of the two variables were recorded in the youngest age group. The frequency of head injuries and the number of selected manifestations of the craniocerebral trauma decreased with age.
