Wild Boar Attacks

Common Peroneal Nerve Injury Caused by a Wild Boar Attack

Wild boar-inflicted nerve injuries have been very rarely reported in the literature. A 62-year-old man was attacked by a wild boar in eastern Turkey and brought to the emergency department. He had 5 lacerations on the lower extremities and 2 on the posterior thoracic region. In addition to soft tissue lacerations, he sustained a complete laceration of the left common peroneal nerve with a foot drop. The common peroneal nerve was repaired primarily the day after the attack. The patient was discharged after a short hospital stay without any immediate complications; however, at the 10-mo follow-up, he still had a left foot drop.

Penetrating Head Injury Resulting From Wild Boar Attack in Republic of Korea: A Case Report

Few cases of injuries caused by wild boars have been reported in the literature. Here, we present the case of a 64-year-old male patient who was attacked by a wild boar. The patient had a laceration to the right forehead and a penetrating wound in the area before the right auricle. Computed tomography scan revealed traumatic subarachnoid hemorrhage, subdural hemorrhage, right temporal lobe contusion hemorrhage, pneumocephalus, right zygomatic arch and temporal bone fracture, and right coronal process fracture of the mandible. Prophylactically, 2,000 mg of ceftriaxone and 400 mg of moxifloxacin were intravenously administered every 24 hours. An emergency craniectomy was performed because the skull fracture was an open fracture and control of the increased intracranial pressure was necessary. Inactivated Rabies Virus Vaccine was also administered postoperatively. We concluded that, unlike typical wounds from other traumatic causes, the risk of wound infection is higher. In order to reduce morbidity and mortality due to wild boar attacks, rapid stabilization of the patient's vital signs, prevention of infection with appropriate antibiotics, and surgical intervention at the appropriate time and method are necessary.

Spot the odd one out: do snake pictures capture macaques' attention more than other predators?

Detecting and identifying predators quickly is key to survival. According to the Snake Detection Theory (SDT), snakes have been a substantive threat to primates for millions of years, so that dedicated visual skills were tuned to detect snakes in early primates. Past experiments confronted the SDT by measuring how fast primate subjects detected snake pictures among non-dangerous distractors (e.g., flowers), but did not include pictures of primates' other predators, such as carnivorans, raptors, and crocodilians. Here, we examined the detection abilities of N = 19 Tonkean macaques (Macaca tonkeana) and N = 6 rhesus macaques (Macaca mulatta) to spot different predators. By implementing an oddity task protocol, we recorded success rates and reaction times to locate a deviant picture among four pictures over more than 400,000 test trials. Pictures depicted a predator, a non-predator animal, or a simple geometric shape. The first task consisted of detecting a deviant picture among identical distractor pictures (discrimination) and the second task was designed to evaluate detection abilities of a deviant picture among different distractor pictures (categorization). The macaques detected pictures of geometric shapes better and faster than pictures of animals, and were better and faster at discriminating than categorizing. The macaques did not detect snakes better or faster than other animal categories. Overall, these results suggest that pictures of snakes do not capture visual attention more than other predators, questioning previous findings in favor of the SDT.

Expected and Unexpected Risks for Canoe Travel in Flood Conditions

Flood conditions present dangers for canoe camping, with the highest risk for injury or death related to water submersion of paddlers. Other hazards can exist at high water stages as well. This essay discusses preparation for risks associated with canoe travel during record flood conditions in Alabama's Mobile-Tensaw River Delta. It examines the unique aspects of paddling through submerged forests, route detours necessitated by flooding, potential encounters with dangerous wildlife, and the case of a stinging ant attack on a paddler who unexpectedly comes in contact with a displaced ant colony.

Penetrating Anorectal Injury Caused by a Wild Boar Attack: A Case Report

Wild boar attacks have rarely been reported in the medical literature. This is the case of an 83-year-old male farmer who was assaulted from behind by an injured adult wild boar. He presented with hemorrhagic shock after sustaining injuries to the right profunda femoris artery and right sciatic nerve as well as significant soft-tissue injuries, bilateral iliac wing fractures, an open pneumothorax, and an anorectal injury. The anorectal injury was treated with fecal diversion but was complicated by soft-tissue infection in the surrounding dead space. The patient needed multiple operations, including removal of the distal rectum and creation of a permanent colostomy. In this report, we highlighted the characteristics of anorectal trauma caused by a wild boar attack. We conclude that penetrating anorectal injuries caused by this type of attack can be associated with extensive soft-tissue damage despite externally appearing to be simple puncture wounds. Anorectal combat injuries have demonstrated similar extensive surrounding soft-tissue injuries and propensity for infection; therefore, this case supports adopting a similar treatment strategy, that of serial and radical debridement, to treat certain wild boar injuries.

Bite Wounds Caused by a Wild Boar: A Case Report

A 74-year-old man was attacked by a wild boar while on his way home from his farm in the daytime in winter 2017 on the rural Izu peninsula. He did not provoke the boar; however, hunters were hunting animals in the mountains near the farm around the same time. The boar bit his left leg, and the man fell to the ground. The boar continued biting the man's left leg, and the man delivered a few kicks to the boar's face with his right leg. The boar then bit his right foot and ran away. The man was taken to a hospital, and a physical examination revealed 3 bite wounds on his left leg and right foot. The wounds were irrigated with sterilized saline and closed with sutures under local anesthesia. He received antibiotics and a tetanus toxoid booster. The next day, his wounds were found to be infected, and pus was drained from them. After these treatments, his wounds healed successfully. Animal bite wounds are frequently contaminated. Accordingly, in addition to early proper wound treatment, close observation of the wound is required for both the early detection of any signs of infection and early medical intervention, including appropriate drainage of pus and irrigation as necessary.

Potential effects of incorporating fertility control into typical culling regimes in wild pig populations

Effective management of widespread invasive species such as wild pigs (Sus scrofa) is limited by resources available to devote to the effort. Better insight of the effectiveness of different management strategies on population dynamics is important for guiding decisions of resource allocation over space and time. Using a dynamic population model, we quantified effects of culling intensities and time between culling events on population dynamics of wild pigs in the USA using empirical culling patterns and data-based demographic parameters. In simulated populations closed to immigration, substantial population declines (50-100%) occurred within 4 years when 20-60% of the population was culled annually, but when immigration from surrounding areas occurred, there was a maximum of 50% reduction, even with the maximum culling intensity of 60%. Incorporating hypothetical levels of fertility control with realistic culling intensities was most effective in reducing populations when they were closed to immigration and when intrinsic population growth rate was too high (> = 1.78) to be controlled by culling alone. However, substantial benefits from fertility control used in conjunction with culling may only occur over a narrow range of net population growth rates (i.e., where net is the result of intrinsic growth rates and culling) that varies depending on intrinsic population growth rate. The management implications are that the decision to use fertility control in conjunction with culling should rely on concurrent consideration of achievable culling intensity, underlying demographic parameters, and costs of culling and fertility control. The addition of fertility control reduced abundance substantially more than culling alone, however the effects of fertility control were weaker than in populations without immigration. Because these populations were not being reduced substantially by culling alone, fertility control could be an especially helpful enhancement to culling for reducing abundance to target levels in areas where immigration can't be prevented.

A Case of Recto-Vesico-Cutaneous Fistula Following Perineal Injury by Wild Boar

It is very uncommon for a boar to become aggressive in nature against human unless they are cornered. A wild boar attacked a 24-year-old male from behind in perineal region. At presentation, he had continuous dribbling of urine and fecal matter from perineal wound. On CT-scan, a well defined tract delineated by contrast was seen between postero-lateral aspect of bladder and anterior wall of rectum, and there was contrast extravasation through perineal wound. After resuscitation, fistula was repaired through abdominal approach, and perineal wound was debrided. Emergency physician should be aware of such cases as increasing deforestation and shifting of humans to sub-urban area, have resulted in increased incidences of wild boar attack. Prompt stabilization of patient, treatment of infection with proper antibiotics, prevention of tetanus and rabies infection and emergency surgical interventions are necessary to reduce morbidity and mortality from such trauma.

Fatal tusk injuries from a wild boar attack

Injuries caused by wild boar attacks are rare. The pattern of the tusk injuries by wild boar is rarely been mentioned in literature. Such injuries can be termed "tusk injuries". Herein, we discuss the pattern of a wild boar tusk wound following an attack on a 65-year-old man who sustained fatal injuries as a result.

Case report: Pig attack with successful postexposure prophylaxis management

The domesticated pig or boar is ubiquitous to agriculture around the world and is an important food product in most countries. The males that are able to grow tusks that can approach 5 in are the primary contributor to morbidity and mortality from boar attacks. Literature surrounding domesticated boar attacks is sparse. There are no published cases of domesticated boar attacks that describe successful bacterial postexposure prophylaxis. We present a case report of an attack on an adult female by a domesticated boar.

Swordfish bill injury involving abdomen and vertebral column: case report and review

Background

Penetrating injuries of the abdomen and spinal canal that involve organic material of animal origin are extremely rare and derive from domestic and wild animal attacks or fish attacks.

Case presentation

In this case report we present the unique, as far as the literature is concerned, unprovoked woman's injury to the abdomen by a swordfish. There are only four cases of swordfish attacks on humans in the literature - one resulted to thoracic trauma, two to head trauma and one to knee trauma, one of which was fatal - none of which were unprovoked. Three victims were professional or amateur fishermen whereas in the last reported case the victim was a bather as in our case. Our case is the only case where organic debris of animal's origin remained in the spinal canal after penetrating trauma.

Conclusions

Although much has been written about the management of penetrating abdominal and spinal cord trauma, controversy remains about the optimal management. Moreover, there is little experience in the management of patients with such spinal injuries, due to the fact that such cases are extremely rare. In this report we focus on the patient's treatment with regard to abdominal and spinal trauma and present a review of the literature.
