Computer analysis of erythrocyte catalase activity in diagnosis of mild brain trauma and concussion

A complex investigation of catalase activity in erythrocytes was conducted basing on the results of computer quantitative morphometry of histochemical examination of blood samples from persons with mild craniocerebral trauma. It was found that erythrocytic catalase activity correlates with severity of brain trauma. A novel technique of objective histochemical diagnosis of trauma is described. It provides objective grounds for expert conclusions. Differential features of erythrocytic shape were defined in a small series of micropreparations vs the rest blood samples.     

Forensic medical diagnostics of nitrate and nitrite intoxication

Nitrates and nitrites, accumulating in toxic concentrations in soil, plants, water and foodstuffs, can cause lethal intoxication. The method of isolation, identification and quantitation has been elaborated for their diagnosis. It is based on the isolation of water and subsequent chromogenic test plus photoelectrocolorimetry.     

Personal identification by complex study of characteristics of the teeth and dentition structures

A multimodality dental examination was made and anatomomorphological features of teeth and tooth sequences were studied in 200 policemen using clinical examination, morphological investigation of plaster jaw models, analysis of x-rays and statistics, intraoral videocamera pictures, computer processing. The scheme of creation of dental data bank applicable in personal identification is offered.     

Assessment of unfavorable outcomes of dental care provoked by the patient

Some causes of ineffective dental care because of the patient's negligence were analyzed. In 16 cases the patients ignored recommendations of the dentist and missed visits to the doctor. As a result, the patients developed complications leading to esthetic dissatisfaction, prolonged treatment, repeated prosthetic management.     

Criteria of personal identification by the hyoid bone

We studied 16 sizes of the hyoid bone (HB) from 158 corpses of known gender, Russians, who had died at the age over 15 years by the K. Miller et al program (1998) and 205 back projection electroroentgenograms of the neck of patients of the traumatological hospital in the town of Kirov. HB skeletization was made by the enzymatic drug enzyme. SPSS package and multidimentional statistics (regression and discriminant analyses) were used for data processing. It was established that HB is an informative object of forensic medical personal identification allowing determination of the body length and gender as well as anatomical, x-ray and osteometric individual features. Precision of human body length diagnosis by HB is 6.71-7.26 cm. Therefore, this method should be used in combination with the diagnosis by long tubular bones. Diagnosis of human gender by osteometric signs of HB based on one-dimentional discriminant analysis is feasible in 80-85%, based on canonical discriminant analysis--in 91.1% cases. The method of anatomic, osteometric and roentgenological assessment of HB individuality can be used in personal identification by intravital x-ray of cervical organs and in traumatic defects of HB. The methods may be applied in forensic medical practice in expert examination of body fragments or isolated bone fragments.     

Evidence of Atrocities or Atrocious Use of Evidence: The Controversial Use of Atrocity Film at Nuremberg

This article focuses upon the utilisation of film evidence in criminal proceedings. It describes and evaluates the historical deployment of this type of material at War Crimes Trials, with particular emphasis upon the International Military Tribunal established at Nuremberg, in 1945, in the wake of the Second World War. During this Trial, the prosecution placed reliance upon the film, Nazi Concentration Camps, depicting with graphic realism the horrific barbarism of the Nazi regime. However, this was only made possible by the implementation of innovatory evidential procedures, effectively circumventing the hearsay rule. A comparison is drawn between this, and the current position in England and Wales, following the recent relaxation of the traditional embargo upon hearsay evidence. However, film evidence of the type adduced at Nuremberg may be more prejudicial than probative and should such circumstances arise, the interests of justice may not truly be served.
