Forensic medical characteristics of the injuries inflicted by home-made arbalest

The classification of arbalests as a representative of the class of missiles is presented. Basic design characteristics of such weapon, wounds and damage to cotton targets from shot distances 1, 3, 5, 10 and 15 m are described.     

Forensic medical characteristics of the injuries inflicted by modern sport bow

Modern bows are classified as representatives of darts. Construction characteristics of bows and arrows, damage to experimental cotton targets from shooting distance of 1-15 m are described.     

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.     

Forensic medical aspects of injuries inflicted with self-defense capsaicin aerosols

Toxicological and forensic medical characteristics of capsaicinoids are presented. Capsaicinoids represent a mixture of three basic compounds with similar structure: capsaicine, dihydrocapsaicine, and nordihydrocapsaicine, all of which are the primary components of red pepper extract (Oleoresin Capsicum). The advantages of this group of irritants in comparison with synthetic irritants are discussed. Probable routes of administration of the extract with regard to its hazard for the organism are considered. Results of experimental studies on nonbiological phantoms and volunteers are presented.     

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.     

A complex study of damages inflicted by traumatic shots from the unstem gun PB-4

Possibilities of a complex study of the damage to the body and clothes caused by shots from non-lethal arms (unstem gun PB-4 from a complex Osa) are illustrated by real expert tasks from forensic medical practice. A combination of experimental shots with emission spectral analysis of the objects of the study and targets is validated for determination of the patron characteristics and composition as well as shooting diastance.     

Forensic medical diagnostics of the extent of the thigh skin injury inflicted by motor vehicles of different weight

The authors report the results of an experimental study designed to characterize microstructural changes in the thigh skin caused by the impacts simulating the car wheel loads of different intensity. It was shown that histological methods can be used to discriminate between the intensities of traumatic loading on biological tissues.     

Forensic medical aspects of bone tissue injuries and pathology

This paper reports the results of a number of investigations into forensic medical aspects of bone tissue injuries and pathology that may be of value, both theoretical and practical, for the further studies in this field. The data obtained shed light on the influence of bone porosity on the mechanism of fractures and processes of reparation in the bone tissue. Moreover, they can be used for the purpose of forensic medical expertise.     

Forensic-medical aspects of injuries inflicted by nonlethal arms

Special literature (surgical, forensic-medical and criminalistic) is reviewed on classification, mechanisms of a harmful action and characteristics of injuries inflicted by non-lethal arms. Some details of such arms construction and damaging action are given.     

Characteristic of injuries inflicted by a blank gunshot

The analysis of the data published in the special literature indicates that forensic-medical aspects of the injuries inflicted by blank shots fired from a variety of small-arms weapons remain poorly known or virtually unexplored. Despite considerable variability of such injuries, their forensic-medical examination should include three basic components, viz. the proof of the absence of the injurious action of the shot, differential diagnostics of the consequences of injuries attributable to each traumatic factor of the shot, and experimental simulation of the damages to the human body and the clothes taking into account concrete models of the weapons and the blank cartridge.     

Classification of bone injuries inflicted by the teeth of the carnivorous animals

The morphological characteristics of a variety of bone injuries inflicted by the teeth of the carnivorous animals are presented. The results of their analysis provided a basis for the morphological classification of such traumas taking into consideration the current views of the mechanisms underlying the process of their formation.     

Forensic medical assessment of injuries to the human body and clothes caused by a crossbow arrow

Analysis of the data published in the special literature revealed the lack of information for the objective comprehensive forensic medical evaluation of injuries to the human body and clothes caused by the arrows from different models of crossbows. Morphological characteristics of injuries were shown to strongly depend on the design features of the arrows. This fact can be used to differentiate between injuries inflicted by crossbow arrows and other types of missile weapons.     

Classification of skin injuries inflicted by the teeth of the carnivorous animals

The current approaches to the classification of skin injuries inflicted by the teeth of the carnivores on the human body are discussed. The new morphological classification is proposed taking into consideration the current views of the mechanisms underlying the formation of tooth marks on the integumental tissues of the victims of attacks by carnivorous animals. Morphological characteristics of skin injuries are briefly described in the framework of the new classification.     

About classification of injuries inflicted on humans by carnivorous animals

The biological classification of living species is shown to be inapplicable for the purposes of forensic medical examination. A list of the families of carnivorous animals that may be of forensic medical significance is presented. Their working classification is proposed taking into account the size and behaviour of the animals as well as their body parts and organs with which they may inflict injuries to man in various situations. The main types of wounds caused by carnivores are considered.     

Forensic medical expert evaluation of gunshot injuries of brain skull

Forensic medical experts are offered a set of morphological signs which help identify the gunshot origin of a skull injury, identify which of the injuries is the inlet and which is the outlet, specify the direction of the shot and succession of formation of injuries in cases with several shots. The author suggests evaluating a gunshot wound in the head with due consideration for the mechanisms of its formation. From a complex of signs of a gunshot injury to the brain skull he singles out the tissue defect with a conical channel and the edge of bone defect, additional injury to the external compact plate near the inlet, and type, number, and location of the radial and concentric cracks. Analysis of the morphology of the above listed signs of gunshot injuries to the skull notable extends the potentialities of forensic medical expert evaluation in cases with gunshot injuries.
