Fatal brown bear (Ursus arctos) attack: case report and literature review

Bear incidents are widely publicized, though serious incidents rarely occur. We describe here a case of human death caused by brown bear (Ursus arctos) feet. The brown bear is the biggest carnivore of Greece, reaching up to 200-300 kg weight.This is the first documented fatality involving a brown bear in Greece in which the victim died as a direct traumatic result of the attack.     

The Forensic Pathology of Fatal Attacks by the Large Mammals Inhabiting the Nordic Wilderness—A Literature Review

Fatalities due to animal attacks are rare in forensic medical work but have been known to pose problems due to their potential to mimic homicide. This review summarizes reported cases of fatal attacks by large mammals that inhabit the Nordic wilderness, namely brown bear, moose, wild boar, and wolf, and attempts to elucidate injury patterns that can guide the forensic pathologist to identifying the species and modus operandi of the attacker. A tendency toward a species‐specific injury pattern was observed. Injuries by bear and especially wolf are dominated by biting whereas moose and wild boar do not seem to bite their victims. The bear uses its paws, both for hitting, resulting in crush injury and fractures, and clawing with resulting excoriations and possible penetrating injuries. Crush injuries and fractures appear, on the other hand, to be minimal or absent in attacks by wolf and wild boar.     

Fatal Eurasian Brown Bear Attacks—Two Swedish Fatalities in Modern Times

Fatal bear attacks on humans are uncommon with only one reported case in Sweden since 1902. The bear population is, however, growing and the frequency of confrontations is likely to increase. Case I-A 40-year-old hunter and his dog were found dead near a bear's den. Autopsy showed that a large portion of the face, facial skeleton, and anterior portion of the brain was missing. Autopsy of the bear showed two nonfatal gunshot wounds. Case II-A 61-year-old man and his dog were found dead outside a hunting lodge. Autopsy revealed numerous wounds, including partial evisceration of the intestines. The victim's blood ethanol concentration was 0.27%. These cases confirm the presence of risk factors identified by the Scandinavian Brown Bear Research Project, that is, provocation by a dog, encountering an injured bear, and appearing close to its den. An additional possible factor in case II was ethanol intoxication.

Basic instinct in a feline.

Reported cases in Europe of large felines attacking humans are rare. Recently, in France, a man was attacked in an animal park by a tigress he had raised. He received fatal cervical wounds. This case of death by bites and lacerations, together with others in the recent international literature, underline the hereditary ferocity of such felines and the way in which they prefer to inflict lesions to the neck.     

Human bites and the risk of human immunodeficiency virus transmission.

The risk of human immunodeficiency virus (HIV) transmission following a bite injury is important to many groups of people. The first are those who are likely to be bitten as an occupational risk, such as police officers and institutional staff. Another group are represented by the victims and perpetrators of crimes involving biting, both in attack and defense situations. The possibility of these bites transmitting a potentially fatal disease is of interest to the physicians who treat such patients and the legal system which may have to deal with the repercussions of such a transmission. Bite injuries represent 1% of all emergency department admissions in the United States, and human bites are the third most common following those of dogs and cats. The worldwide epidemic of HIV and acquired immunodeficiency syndrome (AIDS) continues, with >5 million new cases last year and affecting 1 in 100 sexually active adults. A review of the literature concerning human bites, HIV and AIDS, HIV in saliva, and case examples was performed to examine the current opinion regarding the transmission of HIV via this route. A bite from an HIV-seropositive individual that breaks the skin or is associated with a previous injury carries a risk of infection for the bitten individual.     

An Unusual Case of Predation: Dog Pack or Cougar Attack?

Injuries produced by animals are capable of leaving severe patterns and in some cases may result in the death of the attacked individual. Law enforcement authorities may come to erroneous conclusions about the source of the bites based on their awareness of animals present and similarities of the injuries to the untrained eye, with dreadful consequences. Expertise of a carnivore biologist and an odontologist that indentifies the particularities of bite marks may be useful for identifying the attacking species. We present the investigation of a fatal dog pack attack involving a 43‐year‐old man in Bell Ville (Argentina) where the evidence provided by a forensic dentist and a biologist was categorical for establishing the animal species involved. Because of the unusual characteristics of the wounds and the initial hypothesis made by local authorities of a cougar attack, habits and specific patterns of both dog pack and cougar predation on humans are discussed.

Alligator attacks in southwest Florida

The American alligator inhabits bodies of fresh water in Florida and other southeastern states. Although attacks on pets are frequent, alligator attacks on humans are relatively rare because of the animal's natural fear of man. Because of the rarity of attacks on humans, the pathologic findings and pathophysiology of death in such cases have not been well characterized in the literature. We report three cases of fatal alligator attacks that occurred in southwest Florida, each with different pathologic findings and mechanisms of death. Although the cause of death in each case was attributed to the alligator attack, the mechanisms of death differed and included exsanguination because of amputation of an extremity, overwhelming sepsis, and drowning. These cases illustrate the varied pathophysiologies associated with deaths due to alligator attacks on humans and the features that distinguish alligator bites from those of other aquatic predators.     

Fatal and near-fatal animal bite injuries

Fatal and near-fatal maulings of humans by pit bulls have recently become a topic of major public concern, resulting in the passage of laws in some jurisdictions that make the owner of a pit bull criminally liable for manslaughter if his or her pet causes a human death. The authors recently investigated two cases in which children were fatally injured by pet dogs. In the first case, a 17-day-old girl suffered fatal abdominal injuries when attacked by a pregnant Siberian husky. A 2-year-old girl expired from neck wounds inflicted by a pit bull or a rottweiler or both. Because no expert would testify as to which dog caused the fatal injury, the owner of the animals was not charged under a statute which specified criminality only if a pit bull caused the fatal injury. We also examined a 12-year-old boy who attempted to pet a circus tiger; the animal grabbed his arm with its claws and bit off the arm at the shoulder. The arm could not be reattached, but the child survived. These cases and the differentiation of animal bites from other injuries will be presented.     

Death due to attack from chow dog.

It is estimated that between one and four million persons per year are bitten by dogs in the United States. While most injuries associated with the bites are minor, serious sequelae, and even death, may occur. Most victims of fatal dog attacks are children < 1 year of age or elderly women. The most frequent cause of death is hemorrhage and shock from major vessel damage. A case is reported in which an elderly woman was attacked by her pet Chow dog. The victim received multiple superficial abrasions, contusions, and lacerations from the dog attack. A large perforation of the right external pudendal vein and three perforations of the left superficial femoral vein resulted in exsanguination and death. Fractures of the left 2nd through 4th ribs with underlying pulmonary contusion were also found.

注册会计师职务侵权的民事责任问题一直是西方国家学界探讨的难点与重点,因为每一起针对注册会计师的诉讼,往往都演化为整个职业的一种危机.而责任承担是其中的一个重要问题.会计师内部责任理论不能充分体现民事责任制度的惩罚与教育功能,应当予以摈弃,会计师应当也可能单独成为过失侵害第三人民事权利的独立责任主体.     

A case of a fatal Himalayan black bear attack in the zoo

We present a case of a 22-year-old male, who was found inside the cage of Himalayan black bears in the Belgrade Zoo. The victim attended the Belgrade Beer festival the previous night, drinking a lot of beer and acting aggressively. A medico-legal autopsy was performed at the Institute of Forensic Medicine in Belgrade. Autopsy findings showed numerous excoriations all over the body surrounded by bruises, as well as spindle-shaped, oval, and partly irregular wounds of variable size, large defects of skin and subcutaneous soft tissue, fractures of the thyroid and cricoid cartilage, and fracture of ribs. Postmortem toxicological analysis revealed the presence of ethanol in vitreous humor and urine and 11-nor Δ9 tetrahydrocannabinolic acid found in the urine. We discussed similar cases from the available literature in different regions of the world. In conclusion, we pointed out that the presented case does not follow the general pattern of Himalayan bear attacks.     

Implications of trombiculid mite bites: report of a case and submission of evidence in a murder trial

Bites of Trombiculid mites implicated a suspect during a homicide investigation. Clinical documentation of the bites, correlation with entomological studies, and submission of evidence at trial are reported. Insects that have a discrete geographic distribution and leave bites of a characteristic nature may have important forensic science implications.     

Bite motivation of sharks reflected by the wound structure on humans

Bite wounds on humans have rarely been comparatively analyzed, and the behavior leading to such bites is virtually unknown. Nevertheless, the behavior of a shark is reflected in the bite structure and should be an essential part of shark-accident analysis. This paper compares 3 nonfatal accidents on humans, caused by bull sharks, Carcharhinus leucas, that occurred within a 12-month period in the same area of the Bahamas. Examination focused on wound analysis and accident reconstruction to determine the most likely bite motivation of the sharks. Two sharks targeted the left calf areas of the victims; another one bit the back area of a person. Although both calf bites had a very similar appearance, examination concluded that one of them showed the same triggering behavior as for the shark who inflicted the very different-looking back bite. Those 2 bites were competitive, whereas the other calf bite was initially of exploratory nature, turning into a stress-related bite.     

Biomechanical Factors in Human Dermal Bitemarks in a Cadaver Model*

Abstract: In bitemark analysis, the forensic odontologist must consider how the biomechanical properties of the skin contribute to distortion of the bitemark. In addition, one must consider how the bitemark can be distorted by postural movement of the victim after the bite has occurred. A fundamental review of the architecture and biomechanical properties of the dermis is described and evaluated through bites made on cadavers. In order to assess distortion, 23 bites from a single characterized dentition were made on un‐embalmed cadaver skin. Bite indentations were photographed. Following various body manipulations they were re‐photographed in different positions. Hollow volume overlays of the biting dentition were constructed, and metric analysis of the dentition and all bitemarks was completed. The overall intercanine, mesial to distal, and angle of rotation distortion was calculated. Of the 23 bites made, none were measurably identical, and in some cases, dramatic distortion was noted.     

A suggested classification of bite marks in foodstuffs in forensic dental analysis

Bite marks have been reported in flesh, foodstuffs and inanimate objects. Those in foodstuffs occur widely in cases of larceny but also occur in serious crimes such as murder.Evaluation of distinctive characteristics in food bites differs from the corresponding assessment of flesh bite marks in that the assessment is made on the impression made by the labial aspect of the teeth and not on the biting edge, because the teeth penetrate the bitten foods to different depths.The terminology used to describe food bite marks is very varied and a classification of food bites has been formulated in an effort to bring a degree of uniformity to the analysis of such marks.     

Anatomical location of bitemarks and associated findings in 101 cases from the United States

The purpose of this paper is to update and confirm previous studies that examined the anatomical location of human bitemarks. This information is useful to forensic odontologists and pathologists, physicians, and coroners who must be familiar with the most likely locations of bitemarks. The data are also useful for those involved in bitemark research. Using the legal database "Lexis," 101 bitemark cases were identified from the United States Courts of Appeal. Cases were included in the study if they provided details concerning the bitemark, such as anatomical location, number of injuries, and information concerning the victim. Information on 148 bites was collated. These data are presented in tabular and graphical form to allow comparisons between males and females, victims and perpetrators, adults and children, and the crime types associated with human bites.     

Two consecutive fatal cases of acute myocardial infarction caused by free floating thrombus in the ascending aorta and review of literature

Free floating thrombus in the ascending aorta is an uncommon source of acute myocardial infarction. We report on two cases of young women who died of acute myocardial infarction caused by a free floating thrombus in the sinus of Valsalva obstructing the coronary arteries' ostia. The first case reports on a 30-year-old pregnant woman who anamnestically had episodes with short loss of consciousness and weakness. The second case presents a 37-year-old woman suffering from multiple sclerosis with no previous history of thrombotic events. The review of literature revealed a predominance of women (eight females and three males). Interestingly, the coronary arteries bear no preference concerning the right (RCA) or left coronary artery (LCA) being more often occluded by a free floating thrombus. Especially, younger women (mean age 45.5 years, range 30-59 years) with no history of cardiac symptoms and without atherosclerotic changes seem to be predispositioned. The hypothesis that thrombus formation in cases without plaque disruption may depend on an endothelial erosion which seems to be more common in younger women and promoted by a hyperthrombogenic state is supported by our two cases. A comprehensive literature search revealed, that these are the first two reports on a free floating thrombus being the cause of fatal acute myocardial infarction in a pregnant woman, respectively, a woman suffering from multiple sclerosis.     

Inquiry into the Scientific Basis for Bitemark Profiling and Arbitrary Distortion Compensation

Abstract: Prediction of dental characteristics from a bitemark (bitemark profiling) and arbitrary photographic distortion compensation are two practices proposed in bitemark analysis. Recent research on the effect of inherent skin tension properties in bitemark analysis suggests that these practices are subject to review. A biting apparatus was used to create 66 bitemarks in human cadaver skin. The bitemarks were photographed, sized 1:1, and evaluated with Adobe Photoshop^®. Metric/angular measurements and hollow volume dental overlays were employed. Distortion produced was calculated and assessed. Results showed distortional ranges were nonuniform both between bites, as well as within each bite. Thus, enlarging/decreasing the photograph uniformly would not correct the distortion that resulted. With regard to bitemark profiling, 38% of the bites created patterns that could be misleading if profiled. Features were present/absent that were inconsistent with the biter’s dentition. Conclusions indicate bitemark profiling and arbitrary distortion compensation may be inadvisable.
