First Report on Medical Treatment and Outcome of Burnt Cattle. Vet Sci 2023; 10:vetsci10030187. [PMID: 36977226 PMCID: PMC10058702 DOI: 10.3390/vetsci10030187] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2023] [Revised: 02/17/2023] [Accepted: 02/23/2023] [Indexed: 03/05/2023] Open
Abstract
The management of livestock affected by fire often comes down to two options: euthanasia or slaughtering. However, the therapeutic approach can be attempted for high-value cattle. The aim of a primary assessment is to identify signs of smoke inhalation injuries, cardiovascular impairment and shock and to determine the severity and extent of burn injuries. Full-thickness burns covering 40% or more of the body are highly unfavorable prognostic factors and are usually fatal. Moreover, it can take several days for the burns to appear in their full extent, leaving the prognosis uncertain. In this case report, the clinical findings, treatment and outcome of two burnt Holstein heifers are described. Daily wound care required cleaning, the removal of eschars and the application of topical antibacterial agents for seven months in order to discharge one heifer. The topical use of honey with a solution of povidone–iodine proved to be affordable and successful, with no residue risks. The other heifer was more severely wounded, and despite the administration of fluid therapy, pain management, anti-oxidants and anti-microbials, after initial stabilization, the animal’s condition worsened, leading to euthanasia. This confirms that the treatment of burnt cattle is possible but challenging due to the late onset of multi-organ failure.

Abstract
Wildfires are common occurrences worldwide that can destroy vast forest areas and kill numerous animals in a few hours. Climate change, rising global temperatures, precipitation, the introduction of exotic species of plants (e.g., eucalyptus), intensive agriculture, and deforestation have increased the number of fires and their intensity and destructive power. Nearly 4% of the global land surface (30–46 million/km2) is burned annually. There are many studies regarding the impact of wildfires on ecosystems, flora, domestic animals, and humans. Even though wildfires are a common and recurrent problem around the world, most of the time, they are a neglected issue, especially regarding wildlife. The information available is scarce and dispersed across several bibliographical references, and the veterinarian teams, most of the time, need to be trained to act in these situations. In this brief review, we describe different species’ behavior during a wildfire, the effects on the ecosystem, and the socioeconomic impact on the region. From a veterinarian’s perspective, we list the major injuries that are expected to be observed and how to proceed. In conclusion, we discuss better prevention and response measures in a wildfire scenario. This information can be used by veterinarians and all the entities involved in the prevention and combat of wildfires, and the general public has an important role in these situations.

Abstract
OBJECTIVE To establish a baseline reference and create a user-friendly chart for normal body surface area (BSA) in the adult domestic cat similar to the "Rule of Nines" chart. DESIGN Prospective cadaveric study. SETTING University Teaching Hospital. ANIMALS Seven adult domestic short-haired feline cadavers of normal body condition (4-6/9) and body weight. INTERVENTION Individual whole-body computed tomography (CT) scan was performed on all cats. Images were analyzed with 3-dimensional technology to measure the BSA. A chart was created, illustrating the individual surface area of each body part. MEASUREMENTS AND MAIN RESULTS Obtained measurements of the cats are different from surface areas of people and dogs. Percentage of total BSA for cats was as follows: head 13%, neck 5%, thorax 20%, abdomen 15%, pelvis and tail 9%, front legs 7% each, and pelvic legs 12% each. CONCLUSION The distribution of BSA between body parts is different in cats compared to dogs and people. A species-specific chart was created to assure a more accurate estimation of BSA in cats.

The Australian 2019/2020 Black Summer Bushfires: Analysis of the Pathology, Treatment Strategies and Decision Making About Burnt Livestock. Front Vet Sci 2022; 9:790556. [PMID: 35242835 PMCID: PMC8886614 DOI: 10.3389/fvets.2022.790556] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2021] [Accepted: 01/17/2022] [Indexed: 12/03/2022] Open
Abstract
In 2019/2020, Australia experienced a severe bushfire event, with many tens of thousands of livestock killed or euthanized. Little systematic research has occurred to understand livestock bushfire injuries, risk factors for injury, or how to make decisions about management of bushfire-injured livestock. Addressing this research gap is important as there is an increasing bushfire incidence globally. This paper presents qualitative research findings about bushfire-injured and killed livestock in the south-east of Australia after the 2019/2020 Australian bushfires. We describe observed pathology, treatments used, and risk factors for injury, then use thematic analysis to understand decision making about managing fire-injured livestock. Livestock injured by the fires showed pathology predominantly associated with the common integument (feet, hooves and skin) and signs of acute respiratory damage. It could take several days for the full extent of burns to become apparent, leaving prognostic doubt. Treatment strategies included immediate euthanasia, salvage slaughter, retention for later culling, treatment and recovery on farm, hospitalization and intensive treatment, or no intervention. Risk factors reported for livestock injury included lack of warnings about an impending fire, the type and amount of vegetation around livestock and the weather conditions on the day the fire reached livestock. Moving stock to an area with little vegetation before fire arrived was seen as protective. Decision making regarding injured livestock appeared influenced by three main themes: (1) observations on the severity of pathology, clinical signs and level of prognostic doubt, (2) pre-existing beliefs about animal welfare (responsibility to minimize unnecessary suffering) and (3) assumptions about the future. The management of livestock was largely appropriate due to the rapid provision of veterinary expertise. However, it is likely that some injured livestock were euthanized due to conservative veterinary advice driven by a lack of opportunity to re-assess stock, with impacts on farmers. In future, resourcing regular revisits of injured livestock to manage risks of gradual progression of burn pathology may facilitate more accurate prognostic assessment, provided injured animals can receive appropriate pain relief. In addition, a more comprehensive burns classification system linked to prognosis that can be rapidly applied in the field may assist assessments.

Abstract
CASE DESCRIPTION A 3-year-old 27-kg female spayed American Bulldog with severe burn injuries caused by a gasoline can explosion was evaluated. CLINICAL FINDINGS The dog had extensive partial- and full-thickness burns with 50% of total body surface area affected. The burns involved the dorsum extending from the tail to approximately the 10th thoracic vertebra, left pelvic limb (involving 360° burns from the hip region to the tarsus), inguinal area bilaterally, right medial aspect of the thigh, and entire perineal region. Additional burns affected the margins of the pinnae and periocular regions, with severe corneal involvement bilaterally. TREATMENT AND OUTCOME The dog was hospitalized in the hospital's intensive care unit for 78 days. Case management involved provision of aggressive multimodal analgesia, systemic support, and a combination of novel debridement and reconstructive techniques. Debridement was facilitated by traditional surgical techniques in combination with maggot treatment. Reconstructive surgeries involved 6 staged procedures along with the use of novel treatments including applications of widespread acellular fish (cod) skin graft and autologous skin cell suspension. CLINICAL RELEVANCE The outcome for the dog of the present report highlighted the successful use of maggot treatment and applications of acellular cod skin and autologous skin cell suspension along with aggressive systemic management and long-term multimodal analgesia with debridement and wound reconstruction for management of severe burn injuries encompassing 50% of an animal's total body surface area.

Abstract
OBJECTIVE To create a chart for estimating body surface area (BSA) for use in canine burn victims, similar to the human Rule of Nines. DESIGN Prospective study, from 2016 to 2017. SETTING University teaching hospital. ANIMALS Nine adult, medium-sized, mesocephalic dogs (5 females, 4 males). INTERVENTIONS Sedated dogs and fresh cadavers underwent full-body computed tomography (CT) scans. A 3-dimensional technique was used to calculate the surface area of specific body parts, as well as the surface area of the whole body. With the obtained measurements, a BSA chart was created. MEASUREMENTS AND MAIN RESULTS Estimates for percent of total BSA obtained with CT images were as follows: head and abdomen 14%, respectively, neck and each of the thoracic limbs 9%, thorax 18%, pelvic limbs 11% each, and pelvis including the tail 5%. The most considerable differences between dogs and people in respect to the Rule of Nines chart were noticed in the head, the pelvic limbs, as well as in the groin region in people as compared with the pelvic/tail area in dogs. The surface areas of the front legs and thorax were the only body parts that corresponded with that of human body surfaces. CONCLUSIONS A chart for estimating canine body surface was created. Given the diversity of dog breeds, sizes, and body conformation, our results cannot be generalized to all dogs. Studies of more diverse populations are warranted.

Abstract
Simple Summary Wildfires are increasing in frequency and severity across the Western United States. Efforts to understand the health impacts on humans are widespread and expanding; however, very little is known about the impact of wildfires and smoke exposure on livestock. This work presents the results of a survey of cattle, sheep, and goat producers in California, Oregon, and Nevada, on their experiences during the 2020 wildfire season. While few direct impacts of fires were reported among the 70 responses, 26% of respondents reported they had to evacuate livestock and 19% reported pasture losses. Indirect losses from smoke exposure, including pneumonia and reproductive losses were reported more broadly. This preliminary work highlights the need to better understand impacts of wildfires on livestock and how policy changes can help support the livestock production industry through these crises. Abstract Wildfires are increasing in frequency and severity across the Western United States. However, there is limited information available on the impacts these fires are having on the livelihood of livestock producers and their animals. This work presents the results of a survey evaluating the direct and indirect impacts of the 2020 wildfire season on beef cattle, dairy cattle, sheep, and goat, producers in California, Oregon, and Nevada. Seventy completed surveys were collected between May and July 2021. While dairy producers reported no direct impacts from the fires, beef, sheep, and goat producers were impacted by evacuations and pasture lost to fires. Only beef producers reported losses due to burns and burn-associated deaths or euthanasia. Dairy, beef, sheep, and goat producers observed reduced conception, poor weight gain, and drops in milk production. All but dairy producers also observed pneumonia. Lower birthweights, increased abortion rates, and unexplained deaths were reported in beef cattle, sheep, and goats. This work documents the wide-ranging impacts of wildfires on livestock producers and highlights the need for additional work defining the health impacts of fire and smoke exposure in livestock, as well as the policy changes needed to support producers experiencing direct and indirect losses.

Abstract
Thermal burns are a major cause of death and suffering around the globe. They can cause debilitating, life-altering injuries as well as lead to significant psychological and financial consequences. Several research works have been conducted in attempt to find a wound healing therapy that is successful. At present, hydrogels have been widely used in cutting-edge research for this purpose because they have suitable properties. This study aimed to see how therapy with chitosan-polyethylene glycol (Ch-Peg) based hydrogels affected the healing of burn wounds in rats. With the concern of public health, xanthan gum (X), boric acid (B), gelatin (Ge), polyethylene glycol (Peg), chitosan (Ch), glutaraldehyde (G), and HPLC-grade water were prepared using X : Ge : G, X : Ge : Peg : G, X : Ge : Ch : G, X : Ge : Peg : Ch : G, X : Ge : B : Ch : G, X : Ge : B : Peg : G, and X : Ge : B : Peg : Ch : G. The produced composite hydrogels were examined for swelling ability, biodegradability, rheological characteristics, and porosity. The 3D structure of the hydrogel was revealed by scanning electron microscopy (SEM). After that, the structural characterization technique named Fourier-transform infrared spectroscopy (FTIR) was used to describe the composites (SEM). Lastly, in a rat skin wound model, the efficacy of the produced hydrogels was studied. Swelling ability, biodegradability, rheological properties, and porosity were all demonstrated in composite hydrogels that contained over 90% water. Hydrogels with good polymeric networks and porosity were observed using SEM. The existence of bound water and free, intra- and intermolecule hydrogen-linked OH and NH in the hydrogels was confirmed using FTIR. In a secondary burned rat model, all hydrogels showed significant wound healing effectiveness when compared to controls. When compared to other composite hydrogels, wounds treated with X : Ge : Peg : Ch : G, X : Ge : B : Peg : G, and X : Ge : B : Peg : Ch:G recovered faster after 28 days. In conclusion, this research suggests that X : Ge : Peg : Ch : G, X : Ge : B : Peg : G, and X : Ge : B : Peg : Ch : G could be used to treat skin injuries in the clinic.

Abstract
As a result of many years of research, the intricate cellular mechanisms of burn injury are slowly becoming clear. Yet, knowledge of these cellular mechanisms and a multitude of resulting studies have often failed to translate into improved clinical treatment for burn injuries. Perhaps the most valuable information to date is the years of clinical experience and observations in the management and treatment of patients, which has contributed to a gradual improvement in reported outcomes of mortality. This review provides a discussion of the cellular mechanisms and pathways involved in burn injury, resultant systemic effects on organ systems, current management and treatment, and potential therapies that we may see implemented in the future.

Abstract
OBJECTIVE To review the evaluation and treatment of patients suffering from severe burn injury (SBI), burn shock, and smoke inhalation injury. Potential complications and prognosis associated with SBI are also discussed. DIAGNOSIS Diagnosis of burn injury and burn shock is based on patient history and clinical presentation. Superficial burn wounds may not be readily apparent for the first 48 h whereas more severe wounds will be evident at presentation. Patients are diagnosed with local or SBI by estimating total body surface area involved using the 'Rule of Nines' or the Lund-Browder chart adapted from the human literature. THERAPY Patients suffering from SBI require immediate and aggressive fluid therapy. Burn wounds require prompt cooling to prevent progressive tissue damage. Due to significant pain associated with burn wounds and therapeutic procedures, multimodal analgesia is recommended. Daily wound management including hydrotherapy, topical medications, and early wound excision and grafting is necessary with SBI. COMPLICATIONS There are numerous complications associated with SBI. The most common complications include infections, hypothermia, intra-abdominal hypertension, and abdominal compartment syndrome. PROGNOSIS The prognosis of SBI in domestic animals is unknown. Based on information derived from human literature, patients with SBI and concomitant smoke inhalation likely have a worse prognosis than those with SBI or smoke inhalation alone.
