Animal-related injuries in a resource-limited setting: experiences from a Tertiary health institution in northwestern Tanzania

Patterns of horse and camel- related injuries: A descriptive analysis from a national trauma registry (2007-2021)

BACKGROUND

The large animal-related injuries are emerging major trauma but remain underestimated public health problem worldwide. We aimed to determine the incidence, clinical characteristics, mechanisms and patterns of horse and camel-related injuries (HCRIs) in a Middle Eastern country.

METHODS

A retrospective analysis of all patients who were hospitalized due to HCRIs was conducted. Data included patient's demographics, mechanism of injury, anatomical location and severity of injury, and hospital outcomes.

RESULTS

Between November 2007 and December 2021, there were 273 hospitalized patients with HCRIs representing1.3 % of the total trauma admissions. Of these, 145 (53.1 %) and 128 (46.9 %) were horse (HRI) and camel-related injuries (CRI) respectively. The most common presenting age group of the cohort was 20-29 years and 88 % were males. Patients with HRIs were younger (27.5 ± 11 years) than CRIs (34 ± 13.5 years). Injuries to the extremities were the most common (62 % vs. 40 %), followed by the head injury (25.5 % vs. 31 %) among the HRIs and CRIs, respectively. The most common mechanism of injury was falling off followed by getting kicked by the HCRIs. Major trauma (ISS ≥12) was found in 23 % of HRIs (47.5 %) and CRIs (52.5 %). Only 5 % of patients had shock index >0.90 on admission; two thirds were due to CRIs. There were four fatalities (1.5 %), all attributed to traumatic brain injury, of which three were due to HRIs and one due to CRIs.

CONCLUSION

This study reveals that HCRIs predominantly affect young adult males and may involve serious injuries, exhibit distinct injury patterns, however, it is associated with low mortality. Preventive measures need to be revisited.

Camel-Related Facial Injuries: A Seven-Year Retrospective Study

Facial injuries caused by camels can be associated with adverse long-term effects on patients' quality of life. We aimed to investigate camel-related facial injuries in Al-Ain City, UAE, focusing on their incidence, types, mechanisms, anatomical distribution, and outcomes, to enhance preventive measures. We retrospectively collected data from all patients who were admitted to our hospital with camel-related facial injuries from January 2014 through January 2021. Thirty-six patients were included; all were males, with a mean (range) age of 31 (14-66) years, 29 (80.5%) were camel caregivers. The most common mechanisms of injury were falling while riding a camel and camel kicks. The head was the most commonly injured region in 52.7%. Twenty-three (63.8%) patients had facial bone fractures. The middle third of the face accounted for 71.4% of the bony fractures. The most performed surgical procedures in our patients were soft tissue laceration repair and open reduction with internal fixation of fractures (ORIF). Camel-related facial injuries affect young adult male camel caregivers working on camel farms. Orbital and maxillary bone fractures are the most predominant fractures requiring operative management. Legislation for compulsory helmet usage may reduce the incidence of these injuries and their serious consequences.

The nature and consequences of camel-related injuries: A scoping review with special reference to Arab Middle Eastern countries

Animal-related injuries are a substantial but under-reported, emerging public health problem contributing considerably to worldwide morbidity and death. Understanding the behavior of big animals may help in injury prevention. Camels are large long-neck ungulates of the genus Camelus that have been domesticated for millennia as a mode of transportation, race, and food source. Camel-related injuries are not well studied when compared with other animals' injuries. Camels can occasionally be very hostile to humans, inflicting serious injuries. These injuries can be caused by camel bites, falls from their backs, kicks, or collisions with motor vehicles. The relative magnitude of each mechanism has never been extensively studied in the literature. Furthermore, the incidence of camel-related injuries is not well reported worldwide. Camels remain a potential cause of serious injuries and a public health problem for some countries in the Middle East. There are gaps in the incidence, risk factors and mechanism, distribution of camel-related injuries. We aimed to summarize the data and draw conclusions pertaining not just to the most common mechanism of injury but to demographics, incidence, severity, and appropriate methods of prevention of camel-related injuries. This scoping review findings will help for better understanding of the nature and consequences of camel-related injuries, and to improve the existing preventive and management strategies.

Pattern of injuries due to wild animal attack among patients presenting to the emergency department: A retrospective observational study

PURPOSE

The human-wildlife conflicts (HWCs) causing nuisances and injuries are becoming a growing public health concern over recent years worldwide. We aimed to study the demographic profile, mode of injury, pattern of injury, and outcome of wild animal attack victims presented to the emergency department.

METHODS

This retrospective cross-sectional study was conducted in the emergency department of a tertiary-care hospital in Eastern India. Data were retrieved from the medical records from May 2017 to May 2021. Patients of all ages and genders attacked by wild animals and secondary injuries were included in this study. Patients with incomplete data, injuries due to the attack of stray and domestic animals and trauma due to other causes were excluded. Demographic profile, mode of injury, the pattern of injury, injury severity score (ISS), radiological pattern, and outcome were recorded. Statistical analysis with R (version 3.6.1.) was conducted.

RESULTS

A total of 411 wild animal attack victims were studied, of which 374 (90.9%) were snakebite injuries and 37 (9.1%) were wild mammalian (WM) attack injuries. The mean age of WM attack victims was 46 years, and the male-to-female ratio was 4:1. Elephant attack injury (40.5%) was the most common WM attack injury reported. Most WM attacks (43.2%) occurred between 4:00 a.m. to 8:00 a.m. The median ISS was 18.5 (13-28), where 54.2% of patients had polytrauma (ISS>15). Elephant attack was associated with a higher ISS, but the difference was not significant compared to other animal types (p = 0.2). Blunt trauma was common pattern of injury in the elephant attack injury cases. Lacerations and soft tissue injuries were common patterns in other animal attacks. Among snakebites, neurotoxic was the most common type (55.4%), and lower extremity was the most common site involved.

CONCLUSION

The young male population is the major victim of HWCs; and elephant is the most common animal involved. There is a need to design scientifically sound preventive strategies for HWCs and to strengthen the preparedness in health establishments to manage victims effectively.

Characteristics and outcomes following motorized and non-motorized vehicular trauma in a resource-limited setting

INTRODUCTION

Despite the ubiquity of motorized vehicular transport, non-motorized transportation continues to be common in sub-Saharan Africa.

METHODS

We performed a retrospective analysis of trauma patients presenting to Kamuzu Central Hospital in Malawi from February 2008 to May 2018. Demographic and clinical variables including injury characteristics and outcomes were collected. We performed bivariate and multivariate logistic regression to determine predictors of mortality following non-motorized vehicular trauma.

RESULTS

This study included 36,412 patients involved in vehicular road injuries. Patients in the non-motorized group had a preponderance of men (84% versus 73%, p<0.01). The proportion of patients with Glasgow Coma Scale > 8 was slightly higher in the non-motorized group (99% versus 98%, p<0.01), though injury severity did not differ significantly between the two groups. A higher proportion in the motorized group had the most severe injury of contusions and abrasions (56% versus 50%, p<0.01). In contrast, the non-motorized group had a higher proportion of orthopedic injuries (24% versus 16%, p<0.01). The crude mortality rate was 4.51% and 2.15% in the motorized and non-motorized groups, respectively. After controlling for demographic factors and injury severity, the incidence rate ratio of mortality did not differ significantly between motorized and non-motorized trauma groups (IRR 0.91, p=0.35).

CONCLUSIONS

Non-motorized vehicular trauma remains a significant proportion of morbidity and mortality resulting from road traffic injuries. The injury severity and incidence rate ratio of mortality did not differ between motorized and non-motorized trauma groups. Health care providers should not underestimate the severity of injuries from non-motorized trauma.

Characteristic and outcomes of human and animal bites in Malawi

INTRODUCTION

Bites are an important contributor to traumatic injury worldwide. In low- and middle-income countries, data regarding bite injuries outside of rabies is limited. Therefore, we sought to describe the injury characteristics and outcomes of bites in Lilongwe, Malawi, and determine risk factors for animals and human bites.

METHODS

We performed a retrospective analysis of the Kamuzu Central Hospital trauma registry from 2008-2018. We performed Bivariate analyses comparing bite to non-bite trauma and human to animal bites. Multivariable Poisson regression modeling then estimated risk factors for bites.

RESULTS

A total of 124,394 patients were captured by the registry, of which 3,680 (3%) had a bite injury mechanism. Human bites accounted for 14.5% of bite injuries, and animals represented the remaining 85.5%. In rare cases, animal bite victims had serious complications, such as amputation (n = 6, 0.2%), orthopedic procedures (n = 5, 0.2%), and death (n = 7, 0.2%). Risk factors for an animal bite included being on a farm, field, or lake and being at home, whereas risk factors for a human bite included alcohol use and being at home.

CONCLUSION

Animal bite injuries in Malawi can confer a risk of serious complications, such as amputation and, in rare cases, death. Alcohol-associated, in-home interpersonal violence is a significant risk factor for human bite injuries. Further studies are needed to identify risk factors for complications and mortality.

Ox cart accidents as a cause of spinal cord injury in Tanzania

STUDY DESIGN

Prospective Study.

OBJECTIVES

To describe a unique site-specific injury mechanism for spinal cord injury: incidents involving ox-carts.

SETTING

Main referral hospital for North-eastern Tanzania.

METHODS

A prospective cohort study on Spinal Cord Injury (SCI) in a tertiary referral center in North-eastern Tanzania was examined for accidents related to the use of ox-carts, a major means of transport in a rugged rural area where the economy is largely based on agricultural practices.

RESULTS

Five out of a total of 163 individuals admitted with SCI were injured in incidents directly related to the use of ox-carts. On admission each of the five individuals had different neurological level and corresponding injury severity as follows; C4 (American Spinal Injury Association Impairment Scale) AIS A), C5 (AIS D), C7 (AIS C), T1 (AIS C) and L1 (AIS D). Two out of the five patients developed secondary complications during their hospital stay.

CONCLUSION

The nature of these injuries highlights the influence of one's environment and social circumstances on the risk of sustaining a SCI. Such cases also serve to illustrate the need for tailored prevention, rehabilitation, and reintegration into society.

Case series of hyena bite injuries and their surgical management in a resource-limited setup: 1-year experience

Animal bites are a significant cause of morbidity and mortality and pose a major public health problem worldwide. Children are reportedly the most common victims of animal bites. Bites may be limited to superficial tissues or lead to extensive disfiguring injuries, fractures, infections and rarely result in death. Recently, human injuries caused by non-domesticated animals are increasingly common as ecosystems change and humans encroach on previously wild land. Wild animals like hyenas have been reported to prey on humans and cattle in parts of Africa. Discussed here are four children out of 11 patients that presented with hyena bites-the children had severe bites to the face and head with extensive soft tissue loss, fractures and concomitant severe infections that led to high mortality, indicating the necessity for advanced intensive care and multidisciplinary treatment needed in such situations.

Incidence of Animal-Bite Injuries Registered in Public Hospitals of Post-Conflict Swat District, Pakistan in 2014

The Swat district, a conflict-hit territory due to Taliban militancy, had a damaged local health infrastructure. Animal-bite injuries leading to rabies is one of the major health concerns in developing countries, especially within conflict zones. The current prospective epidemiological study was conducted to estimate the cumulative incidence of animal-bite injuries, to summarize characteristics of bite victims and biting animals, and to collect information about post-exposure prophylaxis (PEP) practices in Swat district, Pakistan, during 2014. A questionnaire was designed to collect data about the sociodemography of the patients, bite incident situation (provoked or unprovoked), injury pattern, animal type, PEP, and vaccination. Descriptive analyses were conducted using bar graphs, frequency tables, and chi-square tests were used to determine associations. The cumulative incidence of animal-bite injuries was 39 per 100,000 people during the study period (May-August 2014). The majority of incidents were reported from rural regions (77.7%) and were males (76.6%) younger than 10 years (37.3%). Dogs were the most frequent biting animal (86.8%) followed by rats (4.7%). About 77.7% patients washed their wound before arrival at hospital. After an eclipse phase of 10 days, 44 (10.1%) animals developed sign of rabies. The current study has highlighted a topic of interest for health, education, veterinary, and local government policy makers regarding prevention of animal bites, benefits of PEP, vaccination of human and domestic animals, control of stray dogs, and eradication of rabies in developing countries with damaged healthcare structures.

Bear attack pattern and behavior in the Himalayan region: A study from a tertiary care center

BACKGROUND

Reports of injuries caused by bear attacks are scarce in the Himalayan region of India, such as Uttarakhand, which is surrounded by hills and thick forests. We retrospectively studied 18 patients attacked by Himalayan black and sloth bears to understand the pattern of the attacks and their management.

MATERIALS AND METHODS

Patients attacked by bears between January 2018 to December 2019 were retrospectively studied.

RESULTS

Most of the patients were of low socioeconomic status. The incidence was highest between June and December. The attacks mostly caused soft tissue injuries. There were also fractures of facial bones noted in some cases, but there was no mortality. The best outcomes were found in those cases that were managed with generous tissue preservation, rather than aggressive debridement. We could also follow the bear attack pattern. Himalayan black bears and sloth bears were found to be involved in the attacks.

CONCLUSION

Injuries due to bear attacks mainly affect the face and neck. Although there were no cases of mortality in this study, facial disfigurement had a long-lasting impact on survivors. Tissue preservation and early reconstruction had the best outcomes.

Diversity of Spectrum and Management of Animal-Inflicted Injuries in the Pediatric Age Group: A Prospective Study from a Pediatric Surgery Department Catering Primarily to the Rural Population

Introduction:

Animal-inflicted injuries continue to be a major health problem worldwide. In developing countries, the outcome of such injuries, especially in children may be poor.

Aim:

The study aimed to evaluate the diversity of spectrum and management of animal-inflicted injuries in the pediatric age group.

Materials and Methods:

This was a prospective study on animal-inflicted injuries in children between 1 to 15 years of age over a period of 12 months. Data on various parameters such as age and sex, animal species involved, provoked/unprovoked, mechanism of injury, time of injury, prehospital care, injury-arrival interval, pattern and type of injury, trauma score, body region injured, treatment given and complications were collected and analyzed.

Results:

Fifty-two children with animal-inflicted injuries were included, constituting <1% of all trauma cases seen during the study period (male:female = 2:1). The mean age of the cohort was 9.65 years. Domestic animals were responsible in 41 children (78.84%) and wild animals in 11 children (21.16%). Dog bite was the most common (57.69%). Penetrating injury was observed in 40 (76.9%) and blunt injury was observed in 12 (23.1%). The musculoskeletal system was the most common organ-system injured affecting 36 children (69.23%). Thirty-five children (67.3%) after minor treatment were discharged. Seventeen children (32.7%) required admission. Thirty-four children (65.38%) underwent surgical procedures. Wound debridement was the most common procedure performed. Wound infection was observed in 20 children (38.46%) and was significantly higher (P < 0.01) in delayed presenters. The length of hospital stay for the admitted children ranged from 3 to 28 days.

Conclusion:

Animal-inflicted injuries are rare in children and have a wide spectrum of presentation. Severe injuries require extensive resuscitation and expert surgical care. Mild injuries can be managed conservatively with the use of proper dressings, antibiotics, and analgesics.

Delayed death after hyena bite in a 3-year-old Tanzanian boy: the unique reality of neurosurgery in a resource-limited setting

A 3-year-old boy presented after a hyena bite to the skull in Tanzania. A large degloving wound with herniating cerebrum was seen in the right parietotemporal region. A CT scan confirmed a large 8-cm skull defect. The patient was taken for irrigation and debridement, but due to significant tissue loss, the skin could not be closed. CSF leaked from the wound, and two additional operations for attempted closure were undertaken but failed. The plastic surgery team was consulted, but no closure was done because of the procedure's complexity, lack of resources, and cost. CSF diversion could not be performed due to no available lumbar catheter or external ventricular drain. Meningitis developed, leading to severe hyponatremia and death. The current case highlights both the unique mechanism of a hyena bite requiring neurosurgical intervention and the realities of practicing neurosurgery in a low-resource setting.

Animal-related injuries and fatalities: evidence from a large-scale population-based cross-sectional survey in rural Bangladesh

OBJECTIVE

This study determines the magnitude and pattern of animal-related injury mortalities and morbidities in rural Bangladesh.

DESIGN AND SETTING

A cross-sectional survey was conducted in 51 Unions of 7 subdistricts of Bangladesh from June 2013 to September 2013.

PARTICIPANTS

A total of approximately 1.17 million individuals across all age and gender profiles were included in the survey. The participants had to be residents of the seven subdistricts and have provided consent to participate in the study.

PRIMARY AND SECONDARY OUTCOME MEASURES

Animal-related injury characteristics and demographic information was collected in the study. Frequency, proportion and 95% CIs of variables such as type of animal, type of animal attack, activity of the person prior to attack and the seasonality of the injury were reported. Data was then statistically analysed for associations between injury and sociodemographic characteristics.

RESULTS

The incidence rate of fatal and non-fatal animal-related injuries across all ages were 0.7 (95% CI 0.4 to 1.4) and 1635.3 (95% CI 1612.0 to 1658.0) per 100 000 populations, respectively. Non-fatal animal-related injury rates were highest among adults 18 years and older (1820.6 per 100 000 population (1777.2 to 1865.1)), and in males across all age groups. The most common animal injury was wasp/hornet/bee sting (49%), followed by cow/buffalo (25%), dog bite (9%) and snake bites (9%).

CONCLUSIONS

Animal-related injuries are an important public health issue in rural Bangladesh. The incidence of animal-related morbidities was found high in the study area. Males, school-going and productive age groups were at high risk. Immediate attention should be given to prevent these events.

A review of upper limb injuries in bear maul victims: Consistent pattern and inverse relation in severity with facial and scalp injuries

PURPOSE

Bear maul injuries are the most common wild animal inflicted injuries in India. More than 300 bear maul injuries report to our hospital per year.

METHODS

Twenty-one consecutive patients over a period of 1 year reported to our department for orthopaedic management of bear maul injuries. All the patients were referred either from peripheral hospitals or from other surgical departments of our hospital.

RESULTS

All the patients had facial/scalp injuries of variable severity. In all the patients the severity of limb and facial trauma was inversely proportional to each other. Pattern of upper limb trauma in most of the patients was similar. Fifteen patients had either fractures of distal humerus or mid shaft/proximal forearm bone fracture. Two had distal forearm bone fracture, 2 had carpal/metacarpal fractures and 1 had clavicle fracture. Only 1 had lower limb fracture. Thirteen out of 21 patients had associated neurovascular injury of the involved limb. The characteristic feature was extensive soft tissue involvement of the affected limb.

CONCLUSION

Upper limb injuries in bear maul patients usually have similar pattern. The severity of upper limb and facial/scalp trauma is inversely proportional to each other. Multistage orthopaedic surgeries are needed for such complex limb injuries.

Traumatic brain injury due to bull assault in a girl: a case report

ABSTRACT

Traumatic brain injury is a common condition in the emergency services, affecting the pediatric and adult population significantly. Patterns of head injury as well as management principles in children are important differences compared to adults. Traumatic brain injury by bull rush is usually seen in adults but has not been described in children-report a pediatric cranial trauma present bull rush, which to our knowledge is the first report in the literature of this nature.
