RESUMO

Background: Ozone therapy (OT) is a type of treatment that uses ozone gas, which has high oxidizing power. OT has been utilized for various diseases and to accelerate the wound healing process and reduce inflammation. Additionally, OT is a low-cost treatment recommended for patients that can be easily restrained. There are several methods of ozone administration, including topical use through bagging, cupping, or rectal insufflation, in addition to ozonated autohemotherapy. Based on the benefits of OT and the scarcity of reports describing its effects on white-eared opossums (Didelphis albiventris), we report on the use of ozone in the treatment of a severe facial wound in a white-eared opossum. Case: An adult female white-eared opossum weighing 1.6 kg was rescued from a fire. The patient was pregnant, dehydrated, hypothermic and had an extensive burn wound in the facial region. Due to the stress of captivity and its aggressive behavior, the animal needed to be chemically restrained with dexmedetomidine and butorphanol. Following sedation, the cephalic vein was catheterized and intravenous fluid therapy with ringer lactate was started to treat dehydration. Next, enrofloxacin, meloxicam, and tramadol hydrochloride were administered. Body rewarming was performed with thermal bags. The microbial load of the wound was reduced with chlorhexidine degerming solution followed by washing with saline solution. A thin layer of silver sulfadiazine cream was applied to the wound area. Over the following days the patient was treated with OT using the cupping technique combined with ozonated sunflower oil. After the first applications there was an improvement in the appearance of the wound, which initially had a purulent aspect. After 20 days of treatment the wound showed good granulation and there were no signs of infection, and at 45 days of treatment it was completely healed. The patient was then released with her baby. Discussion: Ozone therapy was included in the patient's treatment plan to enhance the tissue repair process in order to reintroduce the animal to the wild in the shortest possible time. The strategy was successful in improving healing and reducing tissue inflammation and infection. Ozone is known to cause the inactivation of microorganisms as a result of the oxidation of phospholipids and lipoproteins present in the cell membrane of bacteria and to interrupt viral replication. Ozone helps in the perfusion of injured tissues, contributing to the entry of humoral components, which control inflammation. Moreover, ozone contributes to increase supply of oxygen and nutrients to tissues and to stimulate increased production of fibrinogen and formation of granulation tissue. Ozone increases the enzymatic antioxidant response, while also playing a role in immunoregulation. Ozone can be used in several ways and via various methods with potential routes including intravenous, urethral, intramuscular, subcutaneous, or intra-articular, in addition to rectal and intramammary insufflation. Immunomodulatory, anti-inflammatory, analgesic, and antiseptic effects can be achieved with different doses and concentrations, which enables its application in different types of pathologies. Because of the aggressive behavior of the animal, in the current case we opted for the cupping technique combined with ozonated oil, both techniques which can be administered easily with only physical restraint of the patient. Cupping allows for the provision of a higher concentration of ozone gas locally whereas the ozonated oil maintains the effect of the gas for slightly longer, enhancing its effect and promoting tissue repair. The present report showed that OT is an effective alternative for the treatment of burn wounds in opossums, without causing adverse effects to the patient or her baby.

RESUMO

Background: Bite injuries are commonly found in small animal clinics, especially in male dogs, due to their habits of fighting and territorial disputes. In general, the lesions are treated with the use of compresses and bandages, however, it is extremely important to carefully evaluate the site, in order to carry out the appropriate treatment. In cases of tissue loss, an increasingly used practice is reconstructive surgery, which launches alternatives for treatment through flaps and skin grafts, promoting healing and satisfactory aesthetic repair. This report describes the case of a dog with a facial bite, treated with reconstructive surgery. Case: A 5-year-old male mixed-breed dog, with a body mass of 5 kg, was treated and submitted to a physical examination, due to the owner's complaint that he had been attacked by another dog, causing a bite on the face. On physical examination, the animal showed normal vital parameters, except for mild hyperthermia due to rectal temperature (39.5°C). On the face, it was possible to observe a lacerative lesion in the temporomandibular and masseteric regions, with loss of skin and muscle, in addition to having an aspect of infection and necrosis. To describe the hematological profile, a blood count was performed, showing no changes. In the biochemical tests, the present alteration was a slight increase in Alkaline Phosphatase (393.8 IU/L). Surgical treatment was indicated through facial reconstruction with a skin graft. After performing the antisepsis, the lesion was debrided, the edges were regularized and the injured tissue was curetted. For reconstruction of the defect, we used a flap obtained through a perpendicular incision at the base of the ear, in a caudal direction, and this flap was pulled and transposed over the wound. Flap synthesis was performed with 3-0 nylon thread. After surgery, a compressive bandage was performed, which was removed after 24 h. It was indicated to avoid exertion in the area and to return in 10 days for the evaluation of the surgery and removal of the stitches. Discussion: Traumatic injuries in animals are being increasingly reported, with male and non-neutered dogs being the most prevalent patients. This report is in line with other studies, with the patient's profile being a male dog, with an average age, in line with the literature. In general, in certain types of wounds, the affected animals can develop sepsis and even progress to death, however, in this case the patient did not show changes in vital parameters and in hematological tests. Reconstructive surgeries are performed with the aim of correcting skin defects and knowledge of the available techniques is important. It is also necessary to carry out a good planning, in order to avoid complications in the trans and postoperative period. In the present case, we chose to use a flap obtained through an incision perpendicular to the base of the ear, transposing it over the wound, in addition to relieving tissue tension through skin divulsion, increasing its elastic potential. The use of bandages is considered extremely important for the success of the surgical procedure, as it provides an efficient barrier against infections, trauma and adhesions. However, we emphasize the need to use ointments, gauzes and bandages concomitantly, in order to have the desired success in the postoperative period. In addition to proper surgical techniques, pain management and infection control are important for patient recovery. It is important to use non-steroidal anti-inflammatory drugs and opioids to obtain analgesia, in addition to antibiotic therapy before and after surgery. The reported case demonstrated that lesions in dogs with skin loss can be reconstructed using skin flaps, with an excellent recovery and good prognosis, as was the case with the patient in this report.

RESUMO

Background: Reconstructive surgery is an important area of veterinary surgery because it allows the reconstruction of large cutaneous defects in areas where a primary approach is not possible. Axial patterns flaps are composed by one direct cutaneous artery and vein, leading to a better blood supply with a good survival outcome. The angularis oris axial pattern buccal flap was introduced for correction of facial defects, but its versatility is not really explored in the existing literature. This article reports the use and complications of the angularis oris axial pattern buccal flap in six dogs, to treat defects in mandibular, temporal or labial regions. Cases: Five mixed breed dogs and one Labrador, with age between 4 and 9-year-old were submitted for surgery and the angularis oris axial pattern buccal flap was used to close the different defects. Causes of defect included a lesion caused by myiasis in three of the dogs, and tumoral removal in the other three, where two were mast cell tumors and one a keratinizing basal cell carcinoma. The regions affected included rostral mandible with oral mucosa, intermandibular region, temporal region and upper lip. Before flap confection the tissue was cleaned, resected and prepared properly, according to each cause of lesion. The flap was made with two parallel incisions, which center was usually the labial commissure, with the dorsal limits at the ventral aspect of the zygomatic arch, and the ventral incision on the ventral aspect of the mandibular ramus. Caudal extension was based on the length needed for surgical closure, but stained between the vertical auditory canal or up to atlas wing. Suture size and pattern depend the region and patient size. Patients were observed closely for any complication in the surgical site. From the six dogs presented here, five got some complications in the surgical site, including: lymphedema (2), suture dehiscence (4) and hematoma (1); however...(AU)

RESUMO

O termo cirurgia reconstrutiva, refere-se à utilização de técnicas de reconstrução tecidual, como flaps, enxertos, na correção de defeitos de pele traumáticos, quando o fechamento primário não é possível devido ao excesso de tensão. São várias as técnicas de cirurgia reconstrutiva, com enxertos e retalhos cutâneos, ou somente a utilização de suturas para alívio de tensão ou incisões de relaxamento. Os enxertos podem ser realizados em forma de malha, lâminas, enxertos punção ou por pinçamento, em tiras ou enxertos de coxins. Já os retalhos podem ser de padrão axial, sendo o mais eficiente, o avanço, transposição e rotacionais. Independente da técnica utilizada, alguns cuidados no pré-operatório são necessários para garantir o sucesso do procedimento, como por exemplo, a utilização da técnica cirúrgica meticulosa e a traumática, com bom planejamento, evitando complicações como excesso de tensão, hematomas, infecção do retalho e comprometimento circulatório. Objetivo deste trabalho foi descrever o relato de um cão atropelado com traumatismo na face em lábio superior esquerdo onde foi necessário fazer uma cirurgia de reconstrução tecidual. Foi atendido em caráter de urgência no serviço do SAMU ANIMAL um cão SRD, aproximadamente 4 anos, fêmea apresentando como queixa principal uma extensa ferida em lábio superior esquerdo. O animal foi encaminhado para o DPBEA de Campinas (departamento de proteção e bem-estar animal) onde foi atendido por médicos veterinários e foi feita a cirurgia de reconstrução tecidual.

RESUMO

Background: Several factors influence the survival and performance of piglets during lactation. Birth weight appears as one of the most important factors affecting the survival of piglets, mainly during the first week after birth. There is also a positive correlation between birth weight and weaning weight. In addition to the birth weight, the presence of oral, umbilical or limb lesions can compromise the performance of suckling piglets, affecting their weaning weight. Although limb lesions are common among suckling piglets, there is little information associating these lesions with piglet performance. The aim of this study was to evaluate the influence of birth weight as well as of oral, umbilical or limb lesions on mortality and performance of piglets at 7, 14 and 21 days of age. Materials, Methods & Results: The study was performed in a pig farm located in Rio Grande do Sul State, Brazil. A total of 2004 piglets were evaluated for the presence of oral (at the first day of life), umbilical and limb lesions (at the end of first and second weeks of life). Piglets were weighed at birth and at 7, 14 and 21 of age. Overall, birth and weaning weights were respectively 1546 ± 8.2 g and 5837 ± 32.0 g (means ± SEM). Mortality rate from birth to weaning was 4.7% and 79.0% of deaths occurred during the first week of life. Piglets with birth weight until 1200g showed pre-weaning mortality higher (P < 0.05) than heavier piglets (13.0% - 47/362 vs 2.9% - 48/1642). The occurrence of oral lesions at the first day of life did not affect the survival of piglets until weaning. Birth weight was positively correlated with weaning weight (r = 0.515; P < 0.001). The difference between lighter (> 600 g - 900 g) and heavier piglets (> 2100 g) was 1477 g at birth and 3229 g at weaning. Occurrence of oral or umbilical lesions did not compromise the piglet performance. The presence of limb lesions affected negatively the weaning weight (P < 0.05), mainly when lesions were present in the second week of life. Body weight at 21 d of age was higher (P < 0.05) in piglets without lesions (5957 ± 30.4 g) than in piglets with lesions at the second week (5417 ± 125.9 g) or in those with lesions at both first and second weeks of life (5218 ± 104.2 g). Discussion: The mortality rate of 4.7% observed during lactation is lower than that observed in other reports. The occurrence of a low mortality rate in this study may refl ect the continuing presence of employees in facilities and intensive care provided to the piglets at farrowing and during the suckling period. In agreement with other studies, lighter piglets presented higher pre-weaning mortality than heavier piglets, and 70.5% of deaths occurred in piglets weighing between 600 g and 1500 g. Birth weight was also shown to be a determinant factor for weight gain until weaning, confirming the results of previous studies. Piglets with a low body weight at birth have low body energy reserves and a reduced ability to maintain their body temperature. These aspects result in a lower colostrum and milk intake, a reduction of passive immunity and undernourishment, resulting in a lower survival and pre-weaning performance. It has been shown that most of limb lesions may cause only discomfort to piglets, but can also act as a gateway to infectious pathogens which result in relevant lesions. The reduction of body weight observed in piglets which had limb lesions during the second week of life may be associated with the fact that from this week onwards there is an increase in daily weight gain of piglets, then limiting their potential body weight gain if lesions are present during this phase.
