RESUMEN
This review delves into the forensic utility of the sternum in creating a biological profile, focusing on sex, stature, and age estimation. Emphasizing the sternum's significance in challenging scenarios, the study supports the combined length of the manubrium and sternal body as a crucial indicator in sex and stature estimation. However, it highlights the need for caution in applying findings across diverse populations and questions the reliability of Hyrtl's law. Age estimation, primarily based on morphological changes and ossification ages, is explored, with one study showing promise but requiring further validation. While acknowledging the sternum's advantages, the review underscores potential limitations and the absence of specific studies on ancestry estimation, leaving this aspect open for future research. In conclusion, the review provides a comprehensive overview of the sternum's forensic applications, urging continued research to enhance accuracy and applicability.

This review article highlights the crucial role of organ weights and dimensions as key indicators in forensic diagnosis. Organ weight changes serve as valuable markers for pathological conditions, aiding forensic doctors in interpreting autopsy findings. The review emphasizes the importance of precision in establish- ing organ reference values, considering factors like population-specific norms and correlations with body parameters. Furthermore, it explores the impact of obesity on organ weights, emphasizing the need for updated databases that accurately reflect diverse populations. The article underscores the inadequacy of relying on outdated sources and advocates for creating a comprehensive and updated database of organ weights and dimensions for the local population, essential for accurate forensic interpretations.

Power hammers are mechanised forging devices that constitute a pivotal part of steel manufacturing. Power hammer-associated injuries are a rare occurrence. We report a noteworthy case of a 52-year-old man who sustained a high-energy penetrating injury while working with a power (counterblow) hammer. The man used a sizable disc-shaped metallic object to dislodge the forging wedged in the machine by applying the force of the striking ram on it. On impact, the object ejected and struck the man in the right lateral portion of the chest. The autopsy disclosed extensive damage to the thoracic and abdominal organs. The cause of death was opined to be exsanguination due to penetrating trauma of the heart and transection of the descending aorta. The investigation confirmed a breach of safety regulations. To the best of our knowledge, this is the first power (counterblow) hammer-related fatality in medico-legal literature.

A complex suicide defines a combination of multiple suicidal methods the victim successively or concurrently carries out. We present a case of a 72-year old man found dead on the railtrack, seemingly committing simple train-related suicide. Flobert revolver - a small caliber handgun was found nearby. Herein, we emphasize the significance of a thorough external examination, stress the fact that victim can act after low-energy projectile trauma and match our case to a similar complex suicide.

The muzzle imprint mark characteristically associated with contact or near contact entrance gunshot wounds exemplifies one of the most informative external findings in forensic medical practice. The presence of the muzzle imprint mark on the body's surface proves ballistic trauma, point of entry, and range of fire. Moreover, its appearance and configuration may indicate the type of the involved weapon and the way the firearm had been positioned and held at the time of discharge. In this paper, we present the contact shot wound pattern of an 83-year-old man who committed suicide with a Frommer Stop 12â¯M autoloading pistol of caliber 7.65â¯mm Browning. Initially, the muzzle imprint mark configuration in relation to the entrance gunshot defect in the victim's right temple indicated an unusual application or orientation of the pistol's barrel during discharge, thus, strongly suggesting a non-suicidal act. However, a critical confrontation of postmortem findings along with the results of ballistic expertise provided a clear explanation, which comprised the remarkable construction and unique muzzle design of the used handgun.

We describe the case of a 36-year-old male who presented to hospital with acute respiratory distress, and hemoptysis after intravenously injecting 20 milliliters of pure gasoline. Despite maximum supportive care he died without a definitive diagnosis 4 hours after presentation to the hospital. Postmortem examination confirmed diffuse pulmonary hemorrhage as a cause of death. Our case highlights the key clinical, and pathological features of this very rare poisoning with a volatile substance and reminds clinicians to consider it as a potential cause of hemoptysis and pulmonary hemorrhage.

Autoerotic deaths refer to fatalities occurring during individual, solitary sexual activity, in which some device, situation, or act is used to gain or boost the sexual arousal of the subject. Anorectal autoeroticism is an autoerotic paraphilic activity that pertains to the self-insertion of various objects into the anal canal and rectal cavity to gain or heighten the subject's sexual drive. Although most foreign bodies inserted into the rectum do not cause significant injury, the introduction of some objects into the rectum might have unpredictable and even fatal effects. In this paper, we describe an intriguing autoerotic case of a 35-year-old male who sustained an explosive rectal trauma as a result of the unanticipated bursting of an expandable rubber pipe stopper that he inserted into his rectum and hyperinflated via an air blow gun connected through a pressure pipe to a centralized air-distribution system. The man sustained a circular abruption of the rectum with partial avulsion of the abdominal wall, associated with bleeding into the abdominal cavity and chest wall, and died before admission to the hospital. A police investigation revealed that the victim was a regular contributor to several web forums dedicated to unusual sexual activities. This case raises awareness of the broadening spectrum of methods and experiments associated with autoerotic behavior. We also reviewed the literature pertaining to this topic and outlined some of the characteristics of atypical autoerotic deaths. Although certain autoerotic methods are relatively common, other unusual autoerotic techniques may present novel challenges within the medicolegal field.

Autoerotic death is a rare but recurring phenomenon in forensic medicine. This article presents two cases of unusual autoerotic death with signs of autoerotic asphyxia. Although the first case appeared to be asphyxia, the autopsy confirmed natural cause of death during solitary sexual activity of 69-year-old man found with exposed and bandaged genitals. The other case was asphyxiation utilizing a plastic bag and multiple panties wrapped around the head of 18-year-old man disguised in women´s dress.

Geocaching is a high-tech treasure-hunt game that uses GPS-enabled devices or smartphone apps to find cleverly hidden treasures marked by GPS coordinates that are shared online. Like any other outdoor activity, geocaching is associated with risks of falls, environmental injuries, asphyxia and natural events. Despite the apparent risk of serious injury and potential death, no relevant reports aiming to identify the characteristics of geocaching-related deaths have appeared in the medical literature to date. We report a case of an experienced geocacher who was found suspended from a bridge pillar with his climbing ropes and helmet straps twisted across his face and neck; he had apparently attempted to rappel from a 30-m-high railway bridge to find a geocache. A recording of the rappelling sequence from the camera found on the chest strap assisted in reconstructing what had actually happened. An autopsy confirmed that the cause of death was asphyxiation due to hanging, with the occlusion of the external airways and positional asphyxia serving as contributory factors. The salient features of this unusual case are discussed, and several forensic issues of geocaching are highlighted.

Multiple sclerosis, currently incurable and potentially profoundly disabling demyelinating central nervous system disease, is associated with higher occurrence of suicide as affected individuals are prone to major depression and psychosis. Despite progressively incapacitating neurologic impairment, well-staffed institutions, and limited repertoire of methods of suicide, which prevents patients from purposefully ending their lives, suicide-determined patients typically commit suicide resulting from a medication overdose, sharp force traumata, self-neglect, or deliberate starvation. Here we describe a successful suicide committed by a 39-year-old wheelchair-bound, institutionalized, quadriparetic male patient with a diagnosis of multiple sclerosis with secondary progressive clinical course who utilized his motorized wheelchair to terminate his life. He tied a rope between his neck and wall bars and then propelled the wheelchair forwardly. The acceleration of the wheelchair resulted in ligature self-strangulation. This case report, with a review of the literature, is noteworthy for the rareness of the wheelchair-related fatality combined with an unusual, if not entirely unseen, suicidal mechanism in severely disabled adult.

The concept of spontaneous combustion has huge appeal as an historical fiction but it has no scientific background. However, in some deaths involving fire, a body can burn away virtually completely with minimal thermal destruction to the neighboring environment. We report an extraordinary case of the self-immolation of an elderly woman who set herself on fire with suicidal intentions. The unusual appearance and location of the body closely resembled the phenomenon of so-called spontaneous human combustion because the upper parts of the body were almost totally destroyed by fire, while the legs and surrounding structures remained almost untouched by flames. The results of all investigations proved that the woman set fire to her body using a box of matches and accelerants (concentrated ethanol and a solid firelighter). Near-total combustion of her body subsequently occurred during the postmortem period. The development of alleged spontaneous human combustion requires the following: ignition (external heat source), fuel (molten human fat), a wick (e.g. charred and porous clothing, bedding, or ground), time, and an optimal microclimate for gradual burning.

Laryngohyoid fractures in hanging victims are one of the most studied and paradoxically contradictory topics in forensic pathology. According to literary sources, the incidence of laryngohyoid fractures in hanging varies significantly, from 0% to 100%. To verify the diagnostic significance of these injuries in hanging, we prospectively and consecutively analyzed the occurrence of laryngohyoid fractures in a group of 178 suicidal hanging victims (M/F=150/28, aged 14-94years, mean age=50, complete suspension=111 cases, partial suspension=67 cases) in relation to selected variables (age, sex, weight, the completeness of body suspension, and ligature knot location). Altogether, we identified the following types of laryngohyoid fractures in 129 of 178 cases (72.5%): isolated fracture(s) to the thyroid cartilage in 60 cases (33.7%), combined thyrohyoid fractures in 41 cases (23.0%), isolated fracture(s) to the hyoid bone in 28 cases (15.7%), and no fractures to the cricoid cartilage or the cervical vertebrae. The highest frequency of laryngohyoid fractures was found in lateral hangings (right lateral: 26/34, 76.5%; left lateral: 31/37, 83.8%), whereas the lowest rate was found in anterior hangings (4/11, 36.4%). In lateral hangings, fractures more often occurred contralaterally to the suspension point. Statistical analysis revealed significant associations of the occurrence of laryngohyoid fractures with the age of the victim (p=0.028), with the position of the ligature knot on the neck (p=0.019) and with the age-corrected weight of the victim (p=0.026). In addition, we performed a systematic updated review and critical appraisal of relevant literary sources to report the incidence, fracture patterns, and contributing variables of laryngohyoid injuries in hanging. Both the results of our study and the provided literary synthesis show that if evaluated properly, laryngohyoid fractures in hanging may diagnostically offer far more than just evidence that injury to the neck occurred and may also present research opportunities regarding several issues that should be further analyzed and explained.

Massive progress in developing even more precise imaging modalities influenced all medical branches including the forensic medicine. In forensic anthropology, an inevitable part of forensic medicine itself, the use of all imaging modalities becomes even more important. Despite of acquiring more accurate informations about the deceased, all of them can be used in the process of identification and/or age estimation. X - ray imaging is most commonly used in detecting foreign bodies or various pathological changes of the deceased. Computed tomography, on the other hand, can be very helpful in the process of identification, whereas outcomes of this examination can be used for virtual reconstruction of living objects. Magnetic resonance imaging offers new opportunities in detecting cardiovascular pathological processes or develompental anomalies. Ultrasonography provides promising results in age estimation of living subjects without excessive doses of radiation. Processing the latest information sources available, authors introduce the application examples of X - ray imaging, computed tomography, magnetic resonance imaging and ultrasonography in everyday forensic medicine routine, with particular focusing on forensic anthropology.

Strangulation of the heart appears to be an exceedingly rare mechanical phenomenon that can develop with epicardial pacing wires in individuals undergoing somatic growth. Over the passage of time, owing to size mismatch between a fixed wire length and dynamically growing heart, the epicardial wire may embed around the heart resulting in the progressive over-pressurizing of involved cardiac structures. Depending on the location of the peak constriction pressures, cardiac strangulation may damagingly affect coronary circulation, heart valves function, or physiologic filling of the heart chambers, with risk of myocardial ischemia, decreased cardiac output, acute cardiac failure, ventricular arrhythmias and death. We report a case of a 29-year-old male with sudden cardiac death owing to cardiac strangulation with epicardial pacing wire that had been retained in place almost 30â¯years. At autopsy, an enlarged and abnormally contoured heart was found to be strangulated by an epicardial pacing wire; histopathologic examination confirmed hypertrophy of the myocardial fibers, myofiber disarrangement, and replacement-type fibrolipomatosis. In addition, this article consolidates the available literature on cardiac strangulation by an epicardial wire and highlight relevant clinical and medico-legal features for the forensic professionals.

Vomiting and aspiration of gastric contents into the airways and lungs is a common and well-known clinicopathological entity. This phenomenon might also occur in underwater diving, where it can lead to life-threatening or fatal situations. This article presents two incidents involving diving-related vomiting with associated aspiration of gastric contents. One case, a 39-year-old commercial diver using a full-face diving mask, was fatal and the other was a 33-year-old, female recreational scuba diver in whom underwater vomiting was complicated by pulmonary aspiration of a solid foreign body (a peanut) into the right lower lobe bronchus. The peanut was successfully removed and, following bronchoscopic pulmonary lavage, the patient made an uneventful recovery. The causes and consequences of nausea and vomiting within the underwater environment are discussed and possible interpretative problems are highlighted.
