[Diagnostic criteria of death cause from low temperature in air and water established by traditional expert examination methods]. / Diagnosticheskie kriterii prichiny smerti ot deistviya nizkoi temperatury na vozdukhe i v vode, ustanavlivaemye s pomoshch'yu traditsionnykh metodov ekspertnogo issledovaniya.

Death from general hypothermia is one of the leading causes in the structure of violent death in the Russian Federation. OBJECTIVE: To clarify and supplement the complex of differential diagnostic macro- and microscopic signs of a fatal acute general cold trauma received when person is in the air and water. MATERIAL AND METHODS: The conclusions of forensic medical experts on the bodies of people who died from hypothermia in the air and in water (by 150 observations) were analyzed. Methods of descriptive statistics, calculation of the frequency ratio of signs' occurrence were used. RESULTS: The article provides quantitative assessment of occurrence (detection) rate of diagnostically significant signs established with the help of traditional methods of expert examination. A new classification of diagnostic death signs from hypothermia taking into account their differential diagnostic significance and reflecting the conditions of a person's stay in the air and water in the pre-mortem and post-mortem periods, as well as terminal period mechanisms is proposed. CONCLUSION: The established complexes of signs provide an objective basis for determining death cause in non-obvious conditions when cold exposure is expected to be one of the most damaging factors.

[Causal links in forensic medicine in cases of acute enteric infections]. / Prichinno-sledstvennye svyazi v sudebnoi meditsine v sluchayakh ostrykh kishechnykh infektsii.

One of the main tasks in expertise of living persons is to determine the harm caused to human health. According to the regulations, only harm to human health caused by an injury and causally related with it is taken into account in the forensic examination of a living person. The establishment of a causal link allows to assess correctly the harm severity caused to human health. In this respect, the study of the effect of biological damaging factor on human body (cause) and the result of this interaction (effect) is a new step in modern science. The article presents the analysis of data from the reports of the Russian Reference Center on monitoring of enteric infection agents for 2016-2021; the results of examinations of subjects who suffered from acute enteric infections for 2018-2019 to study causal links in forensic medicine in cases of acute intestinal infections.

[Challenges of expert assessment of injury to health in the case of iatrogenic mastectomy due to erroneous histological verification of an oncological condition]. / Problemy ekspertnoi otsenki vreda zdorov'yu v sluchae yatrogennogo udaleniya molochnykh zhelez vsledstvie oshibochnoi gistologicheskoi verifikatsii onkologicheskoi patologii.

A case of commission forensic medical examination in the St. Petersburg Bureau of Forensic Science of a civil case due to an unfavorable treatment outcome is presented. Patient T., 45 years old; due to erroneous histological verification of oncological pathology, she had both breasts removed and received antitumor treatment. It has been shown that defects in histological diagnosis can lead to errors by clinicians and become the subject of lawsuits by patients accusing healthcare professionals of adverse treatment outcomes. It is emphasized that the current legislation lacks medical criteria and an algorithm for assessing the severity of injury to health in women with one or both breasts removed.

[Current view on stab/cut injuries]. / Sovremennoe sostoyanie voprosa koloto-rezanykh povrezhdenii.

Currently, mechanical trauma is the most significant cause of violent death. The injuries caused by sharp objects rank high in the structure of mechanical trauma. The study objective is to review domestic and foreign literature on the study of stab/cut injuries, identify the main issues and consider new promising diagnostic methods. The stab/cut wound morphology is widely described in the available literature, but little attention has been paid to their study of late postmortem changes. This issue requires consideration since putrefactive corpses (hidden by placing the corpse in water, burying it in the ground, etc.) are often the object of forensic medical examination. New methods for assessing stab/cut injuries are also considered: computed tomography, multilayer computed tomography, scanning electron microscopy, and energy dispersive x-ray spectroscopy. Each of the diagnostic methods has its undeniable advantages and prospects for widespread use in expert practice, but they cannot completely replace the main methods and are intended only to supplement them.
