Morphological features of hemorrhages in the soft tissues of intercostal spaces in rib fractures
Abstract
BACKGROUND: Practical observations show peculiarities of hemorrhages in rib fractures: immature cellular forms are often found in the cellular infiltrate. In nonobvious conditions and when it is crucial to determine the duration, such a polymorphic cellular infiltrate can be mistakenly considered as the result of a post-traumatic inflammatory reaction, affecting the assessment of the duration of the injury.
AIM: To study the composition of the cellular infiltrate in hemorrhages in rib fractures, taking into account their morphological features in cases of various causes of death at different periods after injury.
MATERIALS AND METHODS: A retrospective analysis of cases and an analysis of personal observations of deaths of individuals of different age and sex groups with different causes of death, but with anamnestic data of chest injuries, and of cases of isolated chest injury, aimed at forensic histological examination, were performed. The study sample was divided into main study groups according to established time intervals based on anamnestic data of brief circumstances of the case indicated in the referral documents (“those who died at the scene,” “chest injuries as a result of resuscitation measures,” “victims who lived up to 6 hours,” “victims who lived up to 12 hours,” and “victims who lived up to 24 hours”). The forensic (histological) examinations of deceased individuals with fractured pelvic bones and fractured skull bones and examinations of those with hemorrhages in soft tissues with stab wounds of the chest were compared. Additionally, the comparison sample included deaths of people of both sexes, and different age groups and with various causes of death in different periods after injury. From this sample, subgroups similar to those in the main study were formed for comparison.
RESULTS: Analysis showed that in most victims who died at the scene of the incident, immature cellular forms were found in hemorrhages in the soft tissues of the intercostal space, which gradually decreased over time. Morphological study and analysis of hemorrhages into soft tissues showed no immature cellular forms in traumatic hemorrhages of other locations in all comparison groups.
CONCLUSION: Notably, immature cellular forms in the polymorphic cellular infiltrate and hemorrhages in soft tissues from the intercostal space are not a reactive post-traumatic process and cannot be used to estimate the time and duration (survivability) of the injury. Moreover, the preservation of immature cellular forms in the hemorrhage area has been found to change over time with their gradual decrease by 12 hours.
Characteristics and dynamics of autolytic microscopic changes in myocardial structures after hanging
Abstract
BACKGROUND: Establishing the duration of death is a main challenge in forensic medical examinations of the corpses of persons who died from various external influences. This problem has recently attracted the attention of several researchers in the field of forensic medicine worldwide, whose efforts have been focused on finding new approaches to solving this complex problem. However, to date, methods that allow establishing duration of death more accurately remains to be developed.
AIM: To identify the dynamics of autolytic changes in myocardial structures at different times after death from hanging, making it possible to establish duration of death.
MATERIALS AND METHODS: The histological structure of the myocardium from 132 corpses of persons who died of mechanical asphyxia by hanging was studied. The corpses were of 112 men and 20 women aged 18–61 years. The postmortem period ranged from 6–14 to 72–76 hours, with most deaths occurring at 6–8 hours (9.8%), 9–10 hours (9.1%), 11–12 hours (8.3%), and 13–16 hours (7.6%). Cases with other postmortem periods ranged from 6.8% to 3.8%. In the Zeravshan Valley in Uzbekistan, which includes the main territory of the republic, the hot season usually lasts 3.6 months, from May 27 to September 14, with a maximum average daily temperature of 28°C–32°C. The hottest month of the year in the region is July, with an average temperature of 42°C–45°C. The cold season lasts 3.5 months on average, from November 25 to March 4, with a minimum average daily temperature of 8°C–11°C. Based on this, they were divided into the following subgroups: those who died in conditions of relatively low ambient temperatures (–7... + 14°C; n=63), those who died in conditions of average temperatures (7°С–20°С; n=46), and those who died in conditions of high temperatures (not lower than 25°С–30°С; n=23). In addition to the external temperature, other factors were considered, such as humidity, pressure, wind speed, etc., information on which was obtained through the official website of the Uzhydromet center (https://ru.weatherspark.com).
RESULTS: Under high air temperature conditions, autolytic changes in cardiomyocytes appeared 9–10 hours after death from hanging; by 25–28 hours, an increase in the area of cell cytolysis was observed. Under average ambient temperature conditions, similar changes in cardiomyocytes were noted after 11–12 hours, and by 25–28 hours, cardiomyocyte shrinkage was determined. Under low temperature conditions, similar conditions were found at 13–14 and 25–28 hours. Pronounced destructive changes in vascular structures in high temperature conditions occurred within 19–20 hours after death. The perivascular space greatly expands during the postmortem period, and in average temperature conditions, such states are observed by 21–22 hours and after 23–24 hours in low temperature conditions. In high temperature conditions, autolysis in the vessels developed 11–12 hours after death from hanging. Furthermore, in average temperature conditions, these changes were observed after 13–14 hours and after 15–16 hours in low temperature conditions. Consequently, autolytic changes in the structures of blood vessels and intravascular contents of the myocardium develop at different times in the postmortem period, depending on the temperature conditions of the external environment.
CONCLUSION: Considering the results of the assessment of the degree of development of cadaveric phenomena and those of supravital reactions, the data provided can be used in forensic practice in establishing the age of death after hanging, depending on the temperature conditions of the dry arid zone.
Digitalization in forensic medicine
Abstract
BACKGROUND: A decree of the President of Russia defines the introduction of digital technologies as a national goal for the breakthrough development of the country. The development of digital technologies in forensic medicine ensures the success of individual expert tasks and demonstrates the possibility of digital transformation in forensic activity.
AIM: To examine the attitude of forensic experts toward digital transformation in their professional activity.
MATERIALS AND METHODS: A survey was developed for 77 forensic experts from the Bureau of Forensic Examination of the Republic of Bashkortostan and Voronezh, Kirov, and Samara regions. A questionnaire survey containing six questions with three answer options each was developed in accordance with the purpose and objectives of the study.
The methods of variation statistics, analysis, synthesis, and comparison were used.
RESULTS: This study investigated the level of experts’ understanding of the goals of digital transformation in medicine, assessed the experts’ perception of the process of digital transformation in forensic medicine, analyzed the experts’ awareness of the application of digital technologies in expert practice, determined the attitude of experts toward the digital transformation in forensic medicine, and evaluated the respondents’ opinion on the possible impact of digital technologies on the objectivity of the results of expert studies. The viewpoints of forensic practitioners on the relevance and importance of digital transformation in forensic activity were obtained. The recommendations for optimization of digital transformation in forensic medical activity were generated.
CONCLUSION: Forensic experts show a low level of interest on the issue of digital transformation in forensic activity. In the present case, experts have highlighted the relevance of digital transformation for their professional activity and cognitive importance of digital technologies for expert knowledge.
Forensic characterization of signs of exposure to damaging factors of an explosion
Abstract
BACKGROUND: The use of explosives of different configurations in a confined space affects the surrounding objects, including the civilian population. The effects of explosion in the considered conditions of explosive trauma correspond to those typical for explosive damage, which were considered in the forensic characterization of damaging factors of explosions in the explosive event under study. The injuries sustained from the impact of the damaging factors of explosions are characterized by different manifestations and corresponding sequence. This can be noted in the degree of impact of the damaging factors of explosions on the damaged object and thus contribute to the determination of the center of the explosion.
AIM: To determine the extent of the impact of damaging factors of explosions on the damaged object by morphological signs of explosive damage in the investigated circumstances of the explosion.
MATERIALS AND METHODS: Archival materials of forensic medical examinations of fatal cases of explosive trauma of mass character in conditions of confined space were studied.
RESULTS: The complex effect of damaging factors of explosions on the damaged objects has been found to cause almost instantaneous explosive damage on clothing and surface and internal injuries in the victims of the studied event. The morphological manifestations of such injuries are of a complex, multiple, combined nature. All injuries were classified considering their distribution into groups characterizing the degree of violation of morphological structures of the organism. Thus, in the general structure of all injuries according to the degree of occurrence of their signs, the following were noted: wounds and soft tissue defects (822; 23.6%), fractures (820; 23.5%), hemorrhages (820; 23.5%), bleeding (820; 23.5%), hemorrhages (805; 23.1%), skin abrasions (279; 7.9%), dislocations (215; 6.2%), organ ruptures (76; 2.2%), mechanical clothing injuries (382; 10.9%), and thermal clothing injuries (91; 2.6%).
CONCLUSION: The presented data show the morphological diversity and severity of explosive damage in the studied event, which to some extent can be considered when reconstructing the circumstances of the explosion.
Comparative characteristic of clothing and human body simulator gunshot damage after firing with 12-gauge cartridges loaded with expanding and non-expanding slug
Abstract
BACKGROUND: The study of gunshot damage after firing with 12-gauge cartridges loaded with expanding slugs is interesting, because it has been undescribed in the modern forensic literature.
AIM: To study clothing and the human body simulator experimental gunshot damage after firing with 12-gauge cartridges loaded with expanding and non-expanding slugs.
MATERIALS AND METHODS: Visual and metric methods were used. The process of slug penetration to target was recorded with a high-speed Phantom VEO video camera 710S, with a Zeiss Milvus 1.4/35 lens. Video shooting at a frequency of 24,000 frames per second was conducted.
RESULTS: Clothing and the human body simulators experimental gunshot injuries after firing with 12-gauge cartridges loaded with expanding and non-expanding slugs was analyzed. The main differences of the gunshot damage morphological features were determined by slug terminal ballistics.
CONCLUSION: The experimental study results can be used for forensic identification of structurally similar slugs of 12-gaude cartridges UNO 35 and UNO 35E by the morphological features of the biological tissues and clothing gunshot damage.
Thanatogenesis and forensic assessment of severe acute methadone poisoning
Abstract
BACKGROUND: Modern scientific data show that only 1.1% die from methadone poisoning in medical institutions. Currently available forensic medical data about this nosology were produced from samples obtained from corpses of individuals who has not undergone any previous therapeutic and diagnostic procedure. The dynamics and role of metabolic disorders in the thanatogenesis of acute methadone poisoning and the forensic assessment of such cases have not been widely studied in forensic medicine.
AIM: To perform a forensic medical assessment of fatal cases of acute methadone poisoning in patients admitted to a multidisciplinary hospital and establish the role of metabolic disorders in the occurrence of death.
MATERIALS AND METHODS: A single-center, retrospective, sample, cohort study was conducted. Medical records and data from forensic medical reports were examined. All included observations with a positive determination of methadone were confirmed in the framework of lifetime chemical and toxicological studies and during postmortem forensic chemical studies of the biological environment of corpses. For the final interpretation of the results and evaluation of their statistical significance, the Pearson’s Chi-square (χ2) criterion was used.
RESULTS: A comparative analysis of clinical and forensic data from most cases revealed consistent causes of death established in vivo and posthumously. Moreover, the leading pathological process that led to death was a combination of pulmonary and cerebral edema. The variability in the causes of death in some cases was due to the background pathology determined by thanatogenesis. The life expectancy of patients was determined by the effectiveness of intensive therapy (ventilator, infusion therapy, vasopressor, inotropic support, correction of metabolic disorders) and characterized by background pathologies and duration of hospital stay.
CONCLUSION: A number of main and related conclusions of practical forensic and clinical interest were drawn from obtained data. Notably, in all cases, the fatal outcome of methadone poisoning was associated with metabolic disorders and severe hypoxia. Moreover, the use of antidote therapy with naloxone and wait-and-see techniques without respiratory support in the treatment of such patients is unreasonable.
Reconstructing legal protection for the medical profession in the face of medical disputes during the COVID-19 pandemic from the dignified justice perspective
Abstract
BACKGROUND: Healthcare involves various stakeholders, including hospitals, healthcare professionals, such as doctors, nurses, and others, as well as patients. The direct relationship typically occurs between doctors and patients. In carrying out their duties, doctors always adhere to standard operating procedures, medical records, and informed consent. The COVID-19 pandemic in Indonesia has led to a surge in the number of COVID-19 patients requiring treatment by doctors. On the one hand, doctors and other healthcare professionals face numerous challenges in providing healthcare services, potentially failing to ensure legal certainty for them.
AIM: This study aimed to reconstruct legal protection for the medical profession in medical disputes during the COVID-19 pandemic from a Dignified Justice perspective.
MATERIALS AND METHODS: This research is a legal study based on the Dignified Justice Theory to understand the concept of legal protection for healthcare professionals, particularly doctors, during the COVID-19 pandemic. The research methodology includes a legislative, conceptual, and case approach.
RESULTS: The research results are subsequently analyzed. Based on the research, it is evident that legal protection is derived from regulations related to recognition, protection of rights, and other relevant legal provisions. Legal protection for the medical profession during the COVID-19 pandemic is also framed within the framework of Pancasila, integrated with the Dignified Justice Theory.
CONCLUSION: Legal protection for doctors in the COVID-19 rapid response task force is evident because healthcare professionals have received legal protection through supervision and guidance provided by local governments and their employing institutions in handling COVID-19.
Immaturity of connective tissue as a cause of damage to the dural mining in newborns with extremely low body weight
Abstract
BACKGROUND: Рrematurity is the leading factor of nervous system damage during childbirth. This article presents an analysis of cases of birth injuries in newborns with extremely low body weight, with a study of the structural features of the dura mater and comparison of the results with those of full-term newborns.
AIM: To identify the distinctive features of the structure of the dura mater in newborns with extremely low birth weight and full-term newborns and establish the association between the structural features and its damage during childbirth.
MATERIALS AND METHODS: A retrospective sampling study was conducted. The main group included newborns with extremely low body weight, and the comparison group consisted of full-term newborns with an established fact of birth trauma. The dura mater was studied from the region of the tentorium velum, falx, and sinus drainage; they were compared with the counting of type I collagen fibers using light and polarization microscopy and morphometry.
RESULTS: In extremely low birth weight newborns, severe intradural hemorrhages were found in the dura mater, indicating its overextension due to the configuration of the head. The dura mater includes loose connective tissue, consisting of short type III collagen fibers. In the comparison group, the severity of subarachnoid hemorrhages in the projection of the sutures corresponded to the severity of damage to the septal parts of the dura mater. The dura mater consists of dense fibrous connective tissue and predominantly type I collagen. Morphometry revealed anisotropy in polarized light in <2%–5% of fiber collagens in the main group and >30–50% of fiber collagens in the comparison group. Statistically significant indicators were identified (p <0.001).
CONCLUSIONS: The structural features of newborns with extremely low body weight indicate the morphofunctional immaturity of the connective tissue of the dura mater, which affects its strength characteristics and leads to damage during any type of birth. Consequently, this injury is an injury to a painfully altered organ and therefore does not qualify for the severity of harm to health.
Systematic reviews
Association between forensic DNA and odontology in human identification during mass disaster: a systematic review
Abstract
BACKGROUND: According to the literature, forensic odontology is one of the most effective and affordable scientific techniques for identifying victims of mass disasters. This research methodically reviews the role and function of forensic odontologists in several global mass disasters. Forensic DNA in odontology is associated with the importance of its application in the identification of humans of mass disasters. As the crime rate continues to rise, the field of forensic medicine has evolved significantly. Forensic dentists play a pivotal role in various areas of crime scene investigations, thereby helping solve innumerable mysteries.
AIM: The study aimed to increase the body of knowledge for future research on forensic odontology by conducting a systematic review search to investigate possible forensic DNA in odontology associated with the importance of its application in the identification of humans of mass disasters.
MATERIALS AND METHODS: Six databases, including Google Scholar, PubMed, Scopus, Embase, Web of Science, and ScienceDirect, were analyzed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) quality scale. The literature search, conducted until February 2024, informed important research choices.
RESULTS: A total of 16 (100%) studies related to forensic DNA of mass disasters were identified. Of these, only seven (43.75%) articles related to dental DNA were included in this review. Of the 4,808 articles obtained, 138 duplicates or irrelevant articles were eliminated. Following a full-text review, seven studies were selected based on eligibility criteria. The highest percentage of victims was identified using dental DNA. In a few studies, some samples were insufficient for complete DNA profiling due to factors such as the method of DNA extraction.
CONCLUSION: Forensic odontology has played a significant role in the identification of victims of several mass disasters around the world. Although teeth are an excellent source of DNA for humans, future studies with larger sample sizes, appropriate control groups, and standardized techniques of DNA extraction need to be conducted.

Genetic problems of DNA portrait as part of DNA phenotyping: A review
Abstract
Forensic DNA databases are beneficial for investigating crimes and allow identifying a person using biological traces, provided that information about him/her is already available in the form of a short tandem repeat profile. The same is true for unidentified corpses. When such information is missing from the database, DNA phenotyping can be used. A person’s appearance can be reconstructed based on his DNA, which is already a finding application in forensic practice. Considerable progress is achieved when the hair and eye color, skin pigmentation, and some other features are established. However, the main interest is in the human face. However, developments in this area are limited. The main issue is that multiple genes are responsible for facial features, including a pleiotropic effect. The emergence of such a method such as genome-wide association study made it possible to analyze many gene loci at once for the presence of single-nucleotide substitutions associated with certain genes involved in the formation of a person’s face. However, sequencing of two genomes (or exomes) of each person inherited from the father and mother with phased haplotype assembly of their sequences can be more informative. With this approach, the accurate selection of objects in the form of a large number of twins and their closest relatives is critical, because twins may carry the same nucleotide substitutions, which largely determine their external similarity. Another cohort should be families in which children are very similar to their parents. In this case, it is crucial to conduct triosequencing with phased assembly of their diploid genomes (exomes). Genetic information obtained in this way, which is processed using machine learning and artificial intelligence, allow us to “reach” the necessary genes, increasing the reliability of such DNA portraits.
Forensic medical examination of feces in traces on material evidence: A review
Abstract
This article provides a review of studies on forensic medical examination of feces in traces on material evidence. This issue has long attracted the attention of researchers owing to the need to identify feces in traces on material evidence during the investigation of criminal acts, including sexual assault cases. Review of literature sources has shown that the existing methods of fecal detection include the study of the morphological, enzyme, pigment, and bacteriological compositions of feces. As the methods of laboratory diagnostics improved, the methods of fecal identification also improved from microscopic to high-tech molecular genetic methods. However, despite the advantages, each of the existing methods have their limitations.
Thus, an integrated approach for fecal identification should be developed to identify its micro-traces, study putrefactive objects, differentiate feces from other biological fluids of the human body and animal feces, and perform a comparative study of feces in traces and fecal samples of persons involved to establish their common origin.

Comprehensive forensic medical examination of defects in the provision of orthopedic dental care: A case report
Abstract
In recent years, the number of complications associated with orthopedic dental treatment has increased, which can lead to serious pathologies and conflict situations and negatively affect the quality of life of patients, which entails the professional responsibility of medical workers. A crucial piece of evidence when considering and investigating civil cases to hold medical workers accountable for providing improper medical care (services) in the field of orthopedic dentistry is the conclusion of commission (complex) forensic medical examinations.
During the forensic medical examination of patients’ claims against dental institutions and dentists, issues regarding their organization and production remains to be determined and studied. Scientifically based objective criteria for evaluating professional errors and defects in dental care have not been developed, and effective methods for analyzing therapeutic and diagnostic processes are not used in forensic medical practice, which makes it challenging to comprehensively analyze a specific clinical situation.
This article provides detailed information on the clinical condition of existing teeth and fixed and removable dentures, characteristics of their position in the oral cavity, defects in fixation, and stabilization of dentures. A comprehensive analysis of the possible use of existing removable and nonremovable dental structures for full-fledged chewing function and their aesthetic condition was performed. Significant errors and limitations in the planning, manufacture, and fixation of removable and nonremovable dentures were identified. A comprehensive assessment and recommendations for forensic medical examination in a civil case are provided.
Organizational and legal problems of recognizing an event as an insured event and paying the insured amount to employees of the forensic medical examination bureau as a result of infection with a new coronavirus infection
Abstract
The World Health Organization has repeatedly documented the need to protect healthcare workers, and the outbreak of the novel COVID-19 infection has demonstrated the importance of staff in healthcare organizations during emergencies.
Owing to their professional duties, employees of the forensic medical examination bureau conduct autopsies of the dead, collect biological material for research, and examine victims, accused individuals, and other persons in accordance with the directions and decisions of law enforcement agencies. During work, it is not always possible to determine whether the personnel of a medical organization had contact with infected persons or materials. In this regard, many countries, including Russia, have prepared additional measures, such as additional payments, to protect healthcare personnel. Norms have been developed and implemented to ensure payments in case of infection of employees of medical organizations. This issue is critical in the event of the death of an employee, because of the fact that the family of the deceased may not receive payments if the connection between the death of the employee and his professional activity is not established.
To illustrate the point, this article presents a case of a claim for a lump sum from the wife of a forensic medical expert who, shortly before his death, in the course of his official duties, had examined the corpse of a woman who had died of chronic heart failure exacerbated by a severe viral infection in the emergency room of a central district hospital. The regional department of the Social Insurance Fund of the Russian Federation, the Centre for Occupational Pathology, and the forensic medical examination bureau did not consider the outcome of the expert’s illness as occupational. However, the court, having studied the case materials in the context of the current legislative framework, declared the conclusion of the medical commissions invalid and established that the medical worker’s death was caused by infection with a new coronavirus infection (COVID-19) in the performance of his labor duties.
Some features of forensic medical assessment of punch-cut skin injuries caused by a tourist knife
Abstract
Injuries from tourist and hunting knives are rare in forensic practice. The design of the blades of tourist and hunting knives have a significant impact on the morphological picture of stab wounds, which can cause difficulties to experts in resolving some issues.
At the time of the forensic examination of the corpse, the expert established that the man at home had been stabbed twice in the chest and stomach with one knife. Medical and forensic study showed that the wound on the chest was caused by a flat piercing-cutting instrument such as a knife, the blade of which in its mark-forming parts had a tip, one cutting blade, and a U-shaped butt in cross-section with clearly defined ribs, and the wound on the stomach was caused by a flat piercing-cutting weapon, the blade of which in its mark-forming parts had a tip and two cutting blades. Thus, the wounds were caused by different knives. However, after the investigator provided the probable instrument of injury (a tourist knife), it became clear that both injuries may have been caused by the same object.
The present case shows that in the absence of information about the traumatic stabbing and cutting object and use of only the data of forensic medical examination of the corpse and results of medical and forensic examination of the morphology of skin wounds, erroneous judgments are possible. Therefore, caution should be exercised when considering the possibility of wounding by one or more knives.

“The doctors guide to the correct examination of dead human bodies...” by I.V. Buyalsky (1824): the first original Russian guide to forensic medical examination
Abstract
The year 2024 marks the 235th anniversary of the birth of Ilya Vasilyevich Buyalsky, an outstanding Russian surgeon, anatomist, and forensic physician and Honored Professor of the Imperial Medical and Surgical Academy and academician of the Imperial Academy of Arts. Another anniversary date of this year is associated with Buyalsky’s name: exactly 200 years ago, “The doctors guide to the correct examination of dead human bodies for finding the cause of death, especially in forensic cases,” which was the first original domestic manual on forensic medical examination, was published in the Military Medical Journal. This article comprehensively examined the history of the creation of this work, its main points, and its significance for subsequent generations of Russian forensic medical experts.
The article provides information about the activities of Buyalsky in the field of forensic medical examination. An analysis of his work “The doctors guide to the correct examination of dead human bodies...” is presented.
The present study shows that Buyalsky was one of the founders of forensic thanatology in our country, and the main provisions of “The doctors guide to the correct examination of dead human bodies...” remain relevant to date.

Initial stage of personal identification by dental status in Russia and tools proposed by G.I. Vilga
Abstract
The year 2023 marked the 120th year of the first domestic, scientifically based work on forensic dentistry conducted in Russia. This work was Vilga’s dissertation for the degree of Doctor of Medicine “On teeth in forensic medicine.” The publication of this work indicated the start of the century of forensic dentistry in Russia. Vilga provided the main directions for the future development of forensic dentistry: personal identification, dental injuries, and improper provision of dental care.
Forensic medical identification of a person involves obtaining objective information about the characteristics and biological properties of an unidentified object and comparing them with materials displaying similar characteristics of the wanted person. The theoretical basis for forensic medical identification of a person is forensic medicine and anthropology. In world practice, identification studies to establish an individual’s identity are based on the examination of odontological status, as a source of significant information for establishing the age, sex, and race of a person, identifying individual characteristics and establishing identity. Forensic dentistry is one of the new branches of forensic medicine. It has its own specific features and requires knowledge that goes beyond the scope of forensic education.
This article provides information on the initial stage of personal identification and use of tools required to solve this problem.
At present, many provisions of the doctoral dissertation of Vilga “On teeth in forensic medicine” remain relevant. Thus, the formation of personal identification by dental status in Russia is directly related to the work of Vilga.
