Background: Aural or auricular hematoma is an important and prevalent surgical condition in small animals practice, and commonly reported in companion pets. The condition is characterized by blood accumulation between the pinnae's dermal surface and the underlying perichondrium. In farm animals, most cases present surgical treatment with drainage of serosanguineous fluid from acute cases with clinical evolution ranging from 1 to 5 days. Therefore, the present work reports the clinical features, surgical treatment and outcome of aural hematomas in 3 small ruminants with a chronic evolution (7 to 20 days), detailing the post-surgical complications, such as wound infection and recurrence, and final cosmetic appearance of the pinnae. Cases: Upon physical examination, all animals were alert and presenting a good body condition score. Clinical alteration was restricted to a bilateral (Case 1) or unilateral (Cases 2 & 3) painless, and fluid-filled swelling, presenting doughy consistency masses within the fluid during pinna manipulation. The fluid-filled swellings were located on the concave (Case 1 - left ear & Case 2) and convex (Case 1 - right ear & Case 3) surface of the pinna. No primary pruritic disorders of the pinna were detected, and a diagnosis of traumatic aural hematoma was proposed. Due to the chronicity of the cases, surgical approach was advisable. The small ruminants underwent general anesthesia, and a linear incision over the skin overlying the hematoma was performed (Cases 1 & 2). After removal of blood and fibrin clots, the cavity was flushed and captonated size 0 nylon mattress sutures were performed on either side of the incision, in order to obliterate the dead space. Due to recurrence after 14 days, Case 2 was submitted to a modified surgical approach using a S-shaped incision combined to multiple drainage holes (MDH) using a disposable 6 mm biopsy punch. The same approach has performed in Case 3. Then, size 0 nylon mattress sutures followed by a tight protective pressure and absorbent bandage combined with an Elizabethan collar was applied. Postoperatively, Case 1 presented surgical site infection and the antibiotic was changed after bacterial culture and antibiogram results. Hospital discharge varied from 14 to 19 days' post-surgery. All animals presented some degree of ear retraction and a linear or S-shaped scar on the affected ear, but final cosmetic appearance was satisfactory to all owners. Discussion: Aural or auricular hematomas are a frequent disorder in dogs and cats clinical practice. In sheep, the few reported cases have been associated with pruritic disorders of the pinna, such as ticks infestation and sarcoptic mange. Whilst in goats, traumatic injuries, such as ear tagging and trauma from others goats, are considered the main cause, especially in breeds with pendulous ear. In our cases with chronic evolution (> 7 days), the most important clinical feature was the presence of doughy consistency masses within the fluid, suggesting matured blood and fibrin clots. A linear incision with captonated size 0 nylon mattress sutures was associated to post-surgical complications, such as wound infection and aural hematoma recurrence. Therefore, a S-shaped incision associated to creation of MDH, in order to achieve better drainage, was the chosen approach in the second surgery (Case 2) and on the subsequent patient (Case 3). To the best of our knowledge, this is the first report using the MDH approach in farm animals, that appears to be an effective treatment for chronic aural hematomas in small ruminants.

Background: Expanding chronic hematoma is a relatively common postoperative complication in humans, not in dogs, nevertheless, is important understand this condition because it may affect the animal's health. A hematoma could be formed within hours and usually stabilizes spontaneously with the reabsorption of its content. However, occasionally the hematoma slowly expands, becomes encapsulated and forms a mass, causing a chronic expanding hematoma. Possibly skin and adipose tissue are displaced secondary to trauma, causing the formation of blood-filled cysts surrounded by a fibrous capsule. The aim of this document is to present the first report of a postsurgical chronic expanding hematoma in dog. Case: A case of chronic expanding hematoma secondary to excision of recurrent myxoma in a bitch was described. Physical examination showed a hard, firm, non-mobile mass enclosed within the deep muscular layers. This mass was between the sternum and the cranial abdomen, similar to previous lesions excised by another veterinarian. Fine needle aspiration indicated the presence of blood. Radiology demonstrated that the bone-cartilage tissue was not involved. Due to the size of the mass, a skin stretching pre-suturing technique using self-adhesive tape was applied around the mass 48 h before surgery. The mass was removed with wide excision margins and portions of the affected muscles, but a large wound with great tension was created; consequently, a parallel to the wound incision and the thoraco-lumbar vertebrae was made. Six months after surgery, the animal presented recurrence of the same lesion, which was also removed. The bleeding times were within the normal range, but the animal was diagnosed with hyperadrenocorticism. After both surgeries histopathological exam revealed a hematoma, that had thrombosis and granulation tissue with fibrosis and severe panniculitis, in addition of multifocal, chronic, moderate lymphohistiocytic myositis; all these changes were compatible with a chronic expanding hematoma. Discussion: Chronic expanding hematoma is a mass that grows slowly secondary to hemorrhage and does not exhibit elements of malignancy. However, it can occasionally be confused for a soft-tissue neoplasm. It has been reported frequently in humans but not in small animals. The first case was reported in 2002: 5 puppies with a cervical hematoma classified as a chronic expanding hematoma was described. In addition, 3 cases were reported: 1 cat with perirenal chronic expanding hematoma; 1 bitch with intra-abdominal presentation, and 1 cat with this pathology on the right pelvic limb after an intramuscular injection. The etiology of chronic expansive hematoma is unidentified in dogs, nevertheless, it is stipulated that is not an inflammatory process as previously assumed, but rather a neoplastic process. As in other cases, it was difficult to determine the origin of the chronic expanding hematoma. The coagulation times and platelets count were within ranges. Similarly, it is very complicated to relate hyperadrenocorticism with chronic expanding hematoma because dogs with Cushing's disease generally present hypercoagulopathies. Myxomas are associated with endocrinopathies in humans and dogs, therefore, hyperadrenocorticism is possibly related with this neoplasia. Myxomas have an expansive growth pattern, contrasting with myxosarcomas, which are infiltrating; Although in the present case the skin mass appeared to be invasive, both macroscopical and histopathological appearance of it corresponded to a well-shaped capsule compatible with chronic expanding hematoma. In summary, to the best of our knowledge, this is the first report of a post-surgical chronic expanding hematoma in a dog.

Acute kidney injury (AKI) is a frequent complication of snakebite envenomation, which is still little known in sub-Saharan Africa. This study aims to describe the clinical, biological and ultrasonographic aspects of AKI following severe snakebite envenomation managed in the intensive care unit. Method: A prospective observational survey was performed in Benin over a period of 18 months. All patients suffering severe snakebite envenomation (SBE) were included. The diagnosis of AKI was made using the KDIGO criteria. Kidney ultrasound exam was performed in all patients to assess internal bleeding and morphological and structural abnormalities of the kidneys. Results: Fifty-one cases of severe SBE were included. All patients presented inflammatory syndrome and showed abnormal WBCT whereas bleeding was found in 46 of them (90%). The median time to hospital presentation was three days. The majority of patients were male (M/F sex ratio = 1.55) and the median age was 26. Sixteen patients (31%) showed AKI according to the KDIGO criteria. Severe AKI (KDIGO stage 2 and 3) was observed in three patients, including one stage 2 and two stage 3. Kidney ultrasound revealed three cases of kidney capsular hematoma (6%), two cases of kidney hypertrophy (3%), three cases of kidney injury (4%), two stage 1 KDIGO and one stage 2 KDIGO. Only one patient benefited from hemodialysis. All patients showing AKI recovered without sequels. The median duration of hospital stays was four days. Seven patients died (14%) including four among the 16 AKI patients. Antivenom has been administered to 41 patients (80%). The comparison between patients without and with AKI did not show any significant difference except gender (p = 10-2). Conclusion: AKI is a common complication of severe snakebite envenomation. Resulting from inflammatory and hemorrhagic disorders, AKI may prove to be a short-term life-threatening factor.(AU)

Background: The equine paranasal sinus have a complex anatomy and large compartiments. For this reason, deseasesthat affect these structures may develop for long periods before the animal show any clinical signs, making it difficult tostablish a definitive diagnosis and institute an adequate treatment. Usually, maxillary hematomas reports come from progression of ethmoidal hematomas, and the descriptions of primary maxillary hematomas are rare. This study aims to reportthe clinical features, diagnosis and treatment of a case of a maxillary hematoma not associated with ethmoidal turbinates.Case: An 8-year-old male horse, Mangalarga Paulista, was referred to the Centro de Apoio ao Ensino e Pesquisa FMVZUSP with history of nasal bleeding for over a year. The animal presented deformity on the right side of the face, with significant volume increase on the maxillary bone region and dull sound at percussion, in addition to great painfull sensibilitywhen palpated. The right nare had no airflow, suggesting complete obstruction of the right nasal cavity. In order to betterevaluate, endoscopic and radiographic exams were performed. At the radiographic exam, in ventrodorsal projection, itwas observed an increase of volume and radiopacity, occupying the right antimer of the nasal cavity, with left nasal septum deviation. In the right dorsoventral oblique projection, it was observed the filling of the rostral and caudal maxillarysinus with the content radiopacity as previously described. At endoscopy exam of the right nasal cavity, it was observeda rounded greenish structure on the middle meatus The diagnosis of maxillary paranasal sinus cist was suggested andsurgical removal, through maxillary sinusotomy was recommended.

In Africa, snakebite envenomations are frequently complicated by life-threatening hemorrhagic syndromes. The authors of the present study conducted a prospective analysis at the University Hospital of Parakou (north of Benin) for seven months (January 1 to July 31, 2014) to assess the contribution of ultrasonography to the diagnosis of internal bleedings and management of envenomation. Methods An ultrasound examination was performed in all patients with clinical envenomation regardless of its severity. The study involved 32 patients admitted to the ICU of the University Hospital of Parakou. Results The average age was 27 ± 13.9 years. The main signs of severity were: prolongation of clotting time (88 %), severe anemia (41 %), clinical hemorrhage (47 %), and shock (19 %). The ultrasound imaging showed internal hemorrhage in 18 patients (56 %). There were hematomas (22 %), hemoperitoneum (13 %) or a combination of both (22 %). The occurrence of internal bleeding and hemoperitoneum were mainly related to the delay of hospital presentation (p = 0.007) and the existence of external bleeding (p = 0.04). Thirty patients (94 %) received antivenom. Case fatality rate was 3.1 %. Conclusion Ultrasonography may help in diagnosing internal bleeding, even in patients that did not show external hemorrhages, and evaluating its importance. As a consequence, the management of snakebite victims may be significantly improved.

O hematoma auricular ou oto-hematoma é um acúmulo de sangue dentro das camadas de cartilagem do pavilhão auricular e é frequentemente observado nos cães e raramente nos gatos. A causa dos oto-hematomas ainda não é bem compreendida, no entanto, em muitos casos, parece que a agitação da cabeça ou coçadura das orelhas causada por dor ou irritação associadas com otite externa (geralmente otite bacteriana em cães e otite parasitária por Otodectes cynotis em gatos) são os responsáveis. O objetivo terapêutico para o hematoma auricular consiste na identificação da origem da irritação, drenagem do hematoma, manutenção da aposição dos tecidos, redução da deposição de fibrina e impedimento da recidiva. O caso relatado é de um felino, Siamês, fêmea, 16 anos de idade, 4 kg de peso. A queixa do proprietário era prurido intenso nos ouvidos e aumento de volume no pavilhão auricular direito. No exame clínico foi diagnosticado hematoma auricular direito e observado presença de secreção otológica bilateralmente de coloração escura, aspecto seco e com grande quantidade de ácaros (visualizados macroscopicamente). Foi prescrito para o tratamento da otocaríase diazinon solução otológica e selamectina. O paciente foi encaminhado para cirurgia para a correção do oto-hematoma, apresentando bom resultado. Conclui-se que o procedimento cirúrgico foi adequado

Aural hematoma is a blood accumulation within the cartilage layers of the ear pinna. It is frequently observed in dogs and rarely in cats. The exact cause of aural hematoma is still poorly understood, however, in many cases, the reason seems to be the head shaking or ear scratching,from pain or irritation associated with external otitis (usually bacterial otitis in dogs and parasitary otitis for Otodectes cynotis in cats) are responsible. The therapy objective for aural hematoma consists on identification of the main reason of the irritation, the draining of hematoma, the maintaining of the tissue supply, the reduction the fibrin storage and to avoid recurrence of the hematoma. The reported case is about a 16-year-old female siamese cat, weighing 4 kg. The owner’s complaint was severe itching in both ears and an increase in volume on right aural pinna. Aural hematoma on right ear, presence of dry and dark secretion and a lot of mites in both ears (seen macroscopically), were diagnosticated on clinical examination. The prescripted treatment for ear infestation was diazinon aural solution and selamectine. The patient was taken to surgery to correct the aural hematoma. The result was really good, so the surgical procedure was appropriated.

A placentação e o desenvolvimento das membranas fetais na espécie canina atualmente são estudados de forma extensiva, já que o conhecimento da morfologia da placenta possibilita reconhecer corretamente alterações patológicas e sua possível correlação com a viabilidade neonatal. O presente estudo tem como objetivo a caracterização morfológica e imunohistoquímica de placentas de cadelas provenientes de eutocia e distocia. Para o desenvolvimento deste experimento foram coletadas 80 placentas, de acordo com o tipo de parto as placentas foram divididas em três grupos experimentais, GN (n=40) placentas obtidas de parto normal, GC (n=28) placentas obtidas de cesariana e GAUP (n=12) placentas obtidas de cadelas em atonia uterina primária. Fragmentos 1cm x 1cm foram seccionados da região próxima ao cordão umbilical e armazenados em formol tamponado 10% durante 48 horas, a seguir, foram transferidos para álcool 70%, no qual permaneceram até o processamento para o estudo histopatológico e imunohistoquímico. Foram reconhecidas áreas de hemorragia, necrose, inflamação e calcificação nas placentas dos três grupos estudados. A hemorragia no parênquima placentário foi identificada em todos os grupos experimentais, não apresentando diferença significativa. A necrose evidenciada junto a face materna foi uma constante nos grupos avaliados, entretanto foram observados na região lamelar focos e áreas de necrose no GC e GAUP, porém estes achados não foram estatisticamente relevantes quanto a comparação ao GN. A inflamação foi raramente observada no GN, esteve pouco presente no GC e predominou nas amostras placentárias do GAUP. Os focos de calcificação identificados foram mais notórios no GC e GAUP. Nos grupos estudados foram observadas alterações discretas quanto a integridade histológica dos hematomas marginais. Nas placentas GN a imunomarcação para vimentina mostrou-se intensa e homogênea em toda zona lamelar, fato não ocorrido nas placentas GC e GAUP, que apresentaram a imunomarcação caracterizada pela variação da intensidade. Para citoqueratina não houve diferença na análise da imunomarcação dos três grupos experimentais. A expressão de RP nas placentas GN e GC foi intensa, já GAUP demonstrou expressão fraca ou ausência de expressão. Nas condições em que este trabalho foi realizado utilizando a técnica de imunohistoquímica, não foi possível a detecção de RE¿ nas placentas dos três grupos experimentais Conclui-se que as alterações morfológicas encontradas nas placentas provenientes de eutocia e distocia, embora nunca antes mencionadas em literatura, podem ser consideradas como achados fisiológicos para a placenta da espécie em estudo. A expressão de receptores para progesterona em placentas provenientes de atonia uterina é fraca ou ausente quando comparada a intensa expressão encontrada nas placentas provenientes de parto normal e cesárea. Placentas caninas a termo podem não expressar receptores para estrógeno ¿

Placentation and the development of fetal membranes in dogs are currently studied extensively, since the knowledge of morphology of the placenta enables properly recognize pathological changes and its correlation with neonatal viability. We aimed to characterize morphologically and immunohistochemically placentas of bitches from eutocia and dystocia. For that 80 placentas were collected and classified according to the type of delivery into three experimental groups,GN (n = 40) placentas obtained from normal delivery, GC (n = 28) placentas obtained from cesarean section and GAUP (n = 12) placentas obtained from bitches with uterine atony. 1cm x 1cm pieces were cut from the region near the umbilical cord and stored in 10% buffered formalin for 48 hours following, were transferred to 70% alcohol, which remained until processing for histopathological and immunohistochemical study. In this research, areas of hemorrhage, necrosis, inflammation and calcification were observed in the placentas in all three groups. Hemorrhagic areas were identified in the placental parenchyma in all groups, without significant difference. The evident necrosis in the placenta maternal face was constant in the groups, we observe areas and spots of necrosis in the lamellar region in GC and GAUP, but those findings were not statistically significant when compared to GN. Inflammation was rarely observed in the GN and it was observed in a few samples in the GC, however it was predominant in samples from GAUP. Calcification spots were observed in GC and GAUP. In the studied groups, discrete alterations were observed when histological integrity of marginal hematomas was evaluated. In GN the immunostaining for vimentin proved to be intense and homogeneous throughout lamellar zone, however this was not observed in GC and GAUP, which presented immunostaining characterized by variation of intensity. For cytokeratin there was no difference between experimental groups. The RP expression in GN and GC was intense, but GAUP samples had weak or absent expression. In the conditions in which this work was carried out using the immunohistochemical technique, we could not detect RE¿ in placentas in all three experimental groups. We conclude that most of morphological changes observed in placentas from bitches in eutociaor dystocia, although never before mentioned in literature, can be considered as physiological findings. The expression of progesterone receptors in placentas from bitches in uterine atony is weak or absent when compared to the intense expression found in placentas from normal and cesarean delivery. Estrogen ¿ receptors expression wasn¿t observed in this study

O transporte de animais para o abate é considerada a etapa mais crítica dentro do manejo de pré-abate. Vários são os motivos que influenciam nos efeitos do transporte rodoviário de bovinos de corte e no bem-estar animal e na qualidade de carcaça. O objetivo deste estudo foi descrever os efeitos do transporte rodoviário no bem-estar e na qualidade da carcaça de bovinos de corte destinados ao abate. Foram realizadas avaliações em duas plantas frigoríficas, com 1.038 desembarques, 185 motoristas avaliados e com um total de 19.635 carcaças. Analisando-se os principais efeitos relacionados à caracterização do transporte rodoviário de bovinos em alguns indicadores de bem-estar animal estão relacionados as características das viagens (condição de conservação do veículo, condições das estradas, distância, espaçamento), do condutor (curso na área de bem-estar animal, idade, tempo de experiência em condução de bovinos) e dos animais (raça e sexo). Considerou como variáveis dependentes as frequências de animais deitados, de quedas no desembarque e de hematomas nas carcaças. Os resultados indicaram que todas as variáveis dependentes apresentaram algum efeito sobre o número de hematomas nas carcaças, a porcentagem de animais deitados durante a viagem e a porcentagem de quedas sofridas no desembarque. Destaca-se os efeitos da distância percorrida pelo veículo de transporte, o espaço linear do compartimento de carga por animal e o tempo de experiência e capacitação dos condutores como importantes fontes de variação. Além dessas, o modelo do veículo utilizado para o transporte dos animais, também se mostrou uma forte variável, embora não tenha sido como variável independente nos modelos, devido ao fato da definição do modelo a ser usado no transporte não ser aleatória, dificultando comparações...

Animal transportation is considered the most critical step in preslaughter beef cattle management. The aim of this study was to characterize the road transport of beef cattle and to analyses its impact on cattle welfare and carcass quality. The study was carried out in two slaughterhouses, by assessing the circumstances of 1,038 unloading procedures, interviewing 185 truck drivers and analyzing 19,635 carcasses. The following independent variables were recorded: 1.) vehicle (type and load compartment conditions), 2) road (distance traveled and road conditions), 3.) driver (age, years of experience in cattle transport and attendance to training courses), 4.) animal (breed and gender) and 5.) space available per animal in the load compartment. The dependent variables analyzed were 1.) frequency of animals lying down in the load compartment, 2.) number of falls at unloading and 3.) number of bruises on the carcasses. The results indicated that all dependent variables had some effect on the number of bruises on carcasses and percentages of animals lying down during the trip and of falls at unloading. The distance traveled, the space per animal in the load compartment and the drivers? experience and attendance to capacitation courses were determined to be the most important sources of variation. In addition, the vehicle model, also showed a strong effect on the dependent variables, although the type of vehicle was not included as independent variable, due to the fact of the model definition used for cattle transport was not by random. We conclude that to assure good animal welfare standards during transport and to achieve better carcass quality it is necessary to improve the transport conditions and this can be achieved by using vehicles that offer less risk to the animals, training the truck drivers, and opting for short-distances
