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

Necropsy protocols of the "Laboratório Regional de Diagnóstico" of "Faculdade de Veterinária" of the "Universidade Federal de Pelotas" were reviewed, ranging the period from 2000 to 2018. Three hundred eighty one necropsies, 25 refrigerated and/or formaline fixed organs, and seven biopsies were received, representing 413 samples. Most of these materials were sent by the "Núcleo de Reabilitação da Fauna Silvestre" of "Universidade Federal de Pelotas" (NURFS-CETAS-UFPel) and were from municipalities within the range area of LRD-UFPel influence. Of the 413 cases 55 (13.31%) corresponded to metabolic/nutritional diseases; 50 (12.10%) to trauma; 35 (8.47%) to bacterial diseases/toxi-infections; 30 (7.26%) to parasitic diseases; 28 (6.77%) to fungal diseases; four (0.97%) to viral diseases and 17 (4.11%) to other diseases. Cases where it was not possible to determine the etiology, were in severe autolysis or were inconclusive totaled 194 (46.97%). Metabolic/nutritional diseases and traumatic injuries were the main cause of death in wild birds', being Passeriformes the most affected order.(AU)

RESUMO

Direct road mortality and the barrier effect of roads are typically identified as one of the greatest threats to wildlife. In addition, collisions with large mammals are also a threat to human safety and represent an economic cost to society. We documented and explored the effects of animal-vehicle crashes on human safety in São Paulo State, Brazil. We estimated the costs of these crashes to society, and we summarized the legal perspectives. On average, the Military Highway Police of São Paulo reported 2,611 animal-vehicle crashes per year (3.3% of total crashes), and 18.5% of these resulted in human injuries or fatalities. The total annual cost to society was estimated at R$ 56,550,642 (US $ 25,144,794). The average cost for an animal-vehicle crash, regardless of whether human injuries and fatalities occurred, was R$ 21,656 (US $ 9,629). The Brazilian legal system overwhelmingly (91.7% of the cases) holds the road administrator liable for animal-vehicle collisions, both with wild and domestic species. On average, road administrators spent R$ 2,463,380 (US $ 1,005,051) per year compensating victims. The logical conclusion is that the Brazilian legal system expects road administrators to keep animals, both wild and domestic species, off the road. We suggest an improved coordination between the laws that relate to animal-vehicle collisions and human safety, and the process for environmental licenses that focusses on reducing collisions with wildlife and providing habitat connectivity. In addition, we suggest better management practices, raising awareness and social change with regard to abandoned domesticated animals including horses, cattle, and dogs. This should ultimately result in a road system with improved human safety, reduced unnatural mortality for both domestic and wild animal species, safe crossing opportunities for wildlife, and reduced monetary costs to society.

RESUMO

Primary gallbladder neoplasms occur infrequently in domestic animals and rarely in wild animals. This article describes a case of gallbladder adenoma in a mongoose ( Mungos mungo ) in captivity. Grossly, the gallbladder was moderately distended with a smooth capsular surface. Necropsy showed an irregular, soft, whitish nodule 0.8cm in diameter. Microscopic examination of the nodule showed proliferation of epithelial cells, which projected from the mucosa and formed papillary projections supported by a sparse fibrovascular stroma. Neoplastic cells were well differentiated with mild anisocytosis and anisokaryosis. Based on these histopathological findings, adenoma of the gallbladder was diagnosed.(AU)

Neoplasmas primárias de vesícula biliar são incomumente descritas em animais domésticos e, raramente, afetam animais silvestres. Este trabalho tem por objetivo descrever um caso de adenoma de vesícula biliar em mangusto ( Mungos mungo ) mantido em cativeiro. Macroscopicamente, a vesícula biliar estava moderadamente distendida, com superfície lisa e, em seu interior, havia um nódulo esbranquiçado, irregular, macio, de 0,8cm de diâmetro. Microscopicamente, havia proliferação neoplásica, epitelial, bem diferenciada, com projeções papilares da mucosa contendo células cilíndricas. Observou-se anisocitose e anisocariose leve. Com base nos achados histopatológicos, foi firmado o diagnóstico de adenoma de vesícula biliar.(AU)

RESUMO

Background: The Crab-eating raccoon (Procyon cancrivorus) is a nocturnal mammal and lives in savannah, but loss of their natural habitat makes increase cases of traffic accidents on the roads. A growing number of wildlife are treated in veterinary hospitals, but we have some limitation about the correct interpretation of the diagnostic test, specially because, even the tests were not described. Myelography is a radiographic technique indicated for compressive lesions of the spinal cord that are not seen on plain radiographs. The present report aims to describe, for the first time, a lumbar myelogram performed in a paraplegic crab-eating raccoon after it suffer a traffic trauma. Case: A free living adult, 8-kg, female raccoon was presenting acute paraplegia and swelling in the region of the left humerus was referred at veterinary hospital. The patient was alert and aggressive, good body score and no signs of active bleeding. The animal temper did not allow approaching it; therefore, physical and neurological examinations were not feasible. The raccoon was tranquilized (1.6 mL of nilperidol® intramuscular), anesthetized (propofol, dose-effect intravenous) and tracheal intubation to provide oxygen and the patient was monitored continuously, followed by referred for radiology service. The simple radiograph showed a complete transverse fracture in the humerus and compression [...](AU)

RESUMO

Animais selvagens chegam rotineiramente aos hospitais veterinários com feridas por trauma ou queimadura. Por serem de difícil manipulação, necessitam de contenções químicas para executar simples curativos, prejudicando desta forma o tratamento. A maioria dos protocolos para feridas exige que curativos sejam feitos pelo menos duas vezes ao dia. Na busca por tratamentos alternativos com menos frequência de curativos e consequentemente menos contenções, a biocelulose bacteriana (Acetobacter xylinum) foi utilizada em três diferentes apresentações:biocelulose seca, biocelulose úmida e biocelulose seca com própolis. Nesse trabalho são relatados os resultados do uso deste método em quatro animais: dois tamanduás-bandeira (Myrmecophaga trydactyla), um bugio preto (Aloutta caraya) e uma arara canindé (Ara ararauna). Nestes quatro animais foi possível reduzir a frequência de curativos e contenções, e a cicatrização ocorreu em períodosatisfatório. Os animais permitiram a presença da membrana, e não tentaramremovê-la. Foi observado também que as feridas se mantiveram úmidas e semcontaminação aparente, com intensa neovascularização e granulação. Na maioria dos casos, a biocelulose somente se desprendeu quando a ferida estavapraticamente reepitelizada. Dessa maneira a membrana representa uma nova alternativa no tratamento de feridas cutâneas em animais selvagens .

Wild animals routinely arrive at veterinarian hospitals with burn ortrauma wounds. Because these animals are difficult to handle, they require chemical restraints even for simple dressings, damaging the treatment. Most protocols for wound require that dressings are put up at least twice a day. In search for alternative treatments with less frequent dressing and consequently less restraints, bacterial biocellulose (Acetobacter xylinum) was used and tested in the following three presentations: dry biocellulose, wet biocelulose and dry biocellulose with propolis. In this paper it is reported the results of the use of this method in four animals: two giant anteater (Myrmecophaga trydactyla) a black owler monkey (Aloutta caraya) and ablue and yellow macaw (Ara ararauna). In these four animals it was possible toreduce the frequency of dressings and restraints, and the healing occurred in asatisfactory period. The animals permit the biocellulose on the skin and don't scratch the spot during the healing period. It was also observed that the wounds were kept moist and without apparent bacterial contamination, with intense neovascularization and granulation. In most cases the biocellulose only came off when the wound was practically reepithelized. So these material represent a new alternative for the treatment of cutaneous injury .

RESUMO

Contexto: O manuscrito descreve o ataque não provocado de um jacaré-do-Pantanal a um pescador. Ataques porjacarés são pouco relatados e a espécie do Pantanal raramente causa acidentes.Descrição do caso: A vítima foi mordida na mão direita quando limpava peixes nas margens do rio Paraguai, por umjacaré de cerca de 1,5 m que saiu debaixo da vegetação aquática. O paciente apresentou dor, secreção purulenta e febree procurou auxílio médico, apresentando ferimentos perfurocontusos e perfurocortantes e fratura-arrancamento nosegundo metacarpiano direito. Após cinco dias de internação, houve significativa regressão do processo inflamatório,quando obteve alta hospitalar para posterior acompanhamento ambulatorial.Discussão: Os acidentes por jacarés podem ser muito graves, devido à dentição e à potência das mandíbulas dessesrépteis. Embora algumas espécies amazônicas possam predar seres humanos, o jacaré-do-Pantanal não causa mortes,mas mesmo espécimes de pequeno tamanho podem causar lesões graves e infecção secundária importante, comoobservado no caso.Conclusões: Devido ao potencial traumático e capacidade de inoculação de micro-organismos, as mordidas de jacarésdevem ser encaradas como ferimentos de alto risco pelas equipes de saúde.
