Diagnóstico precoce de acetonemia subclínica em vacas holandesas por mensuração de corpos cetônicos / Early diagnosis of subclinical acetonemia in holstein cows by measuring ketone bodies / Diagnóstico precoz de acetonemia subclínica en vacas holstein mediante la medición de cuerpos cetónicos

O trabalho foi realizado em uma fazenda de exploração leiteira em Castrolanda, no município de Castro ­ PR. O sistema de manejo é free-stall, com 220 vacas da raça Holandesa com RHA305 de 6.740 litros. Foram coletadas amostras de sangue de 18 vacas de pré-parto, 4 dias antes da data prevista para o parto; e nos dias 4, 7 e 12 pós-parto, mediante punção venosa coccígea, utilizando-se SnapTest digital Ketovet®, constituindo 72 amostras, no período de fevereiro a maio de 2020. Em 4 vacas o BHB do sangue total apresentou-se acima do limite para cetose subclínica no quarto dia após o parto e 17 apresentaram-se acima do limite no sétimo dia, declinando em seguida, principalmente devido às intervenções clínicas. As médias e desvios-padrão foram: D - 4: 0,89 ± 0,257061; D 4: 1,05 ± 0,283279; D 7: 1,81 ± 0,456131; e D 12: 1,19 ± 0,437762. O benefício do monitoramento de BHB foi a imediata intervenção clínica, evitando-se a severidade por instalação de quadro clínico e as enfermidades concomitantes.(AU)

Tridimensional models and radiographic study of dorsal laminectomy and thoracolumbar hemilaminectomy in dogs

Purpose: To create three-dimensional anatomical models of the thoracic and lumbar portions of the canine spine that reproduce the vertebral surgical approaches of dorsal laminectomy and hemilaminectomy, and to perform the respective radiographic evaluations of each approach. Methods: In a digital archive of the canine spine, digitally replicate the dorsal laminectomy and hemilaminectomy in the thoracic and lumbar portions and, then, make tridimensional prints of the vertebral models and obtain radiographs in three dorsoventral, ventrodorsal and laterolateral projections. Results: The anatomical models of the surgical spinal canal accesses of the thoracic and lumbar portions showed great fidelity to the natural bones. The created accesses have the proper shape, location and size, and their radiographic images showed similar radiodensities. Conclusions: The replicas of the dorsal laminectomy and hemilaminectomy developed in the anatomical models in the thoracic and lumbar portions are able to represent the technical recommendations of the specialized literature, as well as their respective radiographic images, which have certain radiological properties that allow to make a deep radiological study. Therefore, the models are useful for neurosurgical training.

Relato de caso: tratamento de ferida perfurante no dígito de equino / Case report: treatment of a perforating wound in the equine digit / Caso clínico: tratamiento de una herida perforante en el dedo equino

Apesar dos avanços na medicina equina, certas condições de claudicação ainda representam um desafio significativo para os clínicos veterinários, especialmente quando se trata de afecções distais, como feridas perfurantes no casco do equino. Essas lesões podem afetar estruturas vitais, incluindo a articulação interfalângica distal, o osso navicular, a bolsa do osso navicular, o tendão flexor digital profundo, a bainha sinovial e a terceira falange. O presente estudo tem como objetivo esclarecer que um diagnóstico mais rápido e preciso das estruturas afetadas e do grau de lesões resultantes leva a um tratamento mais eficaz. Além disso, foi demonstrado que o tratamento convencional com antibióticos e anti-inflamatórios não esteroides sistêmicos -AINEs,em combinação com terapias alternativas, como campo magnético pulsado, laser classe III e Ozonioterapia, apresentou um efeito sinérgico com resultados excelentes.(AU)

Despite advances in equine medicine, certain claudication conditions still pose a significant challenge to veterinary clinicians, especially when it comes to distal affections such as puncture wounds on the equine hoof. These injuries can affect vital structures, including the distal interphalangeal joint, navicular bone, navicular bone pouch, deep digital flexor tendon, synovial sheath, and third phalanx. The present study aims to clarify that a more rapid and accurate diagnosis of the affected structures and the resulting degree of injury leads to more effective treatment. Furthermore, it was shown that conventional treatment with antibiotics and systemic non-steroidal anti-inflammatory drugs -NSAIDs, in combination with alternative therapies, such as pulsed magnetic field, class III laser and ozone therapy, presented a synergistic effect with excellent results.(AU)

El presente estudio pretende aclarar que un diagnóstico más rápido y preciso de las estructuras afectadas y del grado de lesión resultante conduce a un tratamiento más eficaz. Además, se demostró que el tratamiento convencional con antibióticos y antiinflamatorios no esteroideos sistémicos -AINE, en combinación con terapias alternativas, como el campo magnético pulsado, el láser de clase III y la ozonoterapia, presentaban un efecto sinérgico con excelentes resultados.(AU)

Experimental model of nephropathy associated with diabetes mellitus in mice

Purpose: Nontransmissible chronic diseases, such as diabetes mellitus (DM) and nephropathy, affect a significant portion of the population, often treated due to injuries that require healing and regeneration. To create an experimental model of associated comorbidities, for healing and regeneration studies, protocols for induction of nephropathy by ischemia and reperfusion (I/R) and induction of DM by injection of streptozotocin (STZ) were associated. Methods: Sixty-four mice (Mus musculus), female, adult, Swiss strain, weighing approximately 20 g, were divided into four groups: G1: control (n = 24), G2: nephropathy group (N) (n = 7), G3, DM (n = 9), and G4: N+DM (n = 24). Arteriovenous stenosis (I/R) of the left kidney was performed as the first protocol. The animals received a hyperlipidemic diet for 7 days after the injection of STZ (150 mg/kg, via i.p.) and an aqueous glucose solution (10%) for 24 h. The animals in the G3 and G4 groups were observed for 14 days before receiving the diet and STZ. The evolution of nephropathy was observed using a urine test strip and the DM, through the analysis of blood glucose with a reagent strip on a digital monitor. Results: The ischemic induction protocols of nephropathy and DM with STZ, associated, were sustainable, low-cost, and without deaths. There were alterations compatible with initial renal alterations, in the first 14 days, such as increased urinary density, pH alteration, presence of glucose, proteins and leukocytes, when compared to the control group. DM was confirmed by the presence of hyperglycemia 7 days after induction and its evolution after 14 days. The animals in the G4 group showed constant weight loss when compared to the other groups. It was possible to observe morphological alterations in the kidneys submitted to I/R, regarding coloration, during surgery and after the end of the observation period, in the volume and size of the left kidney, when compared to the contralateral kidney. Conclusion: It was possible to induce nephropathy and DM associated in the same animal, in a simple way, confirmed with rapid tests, without losses, providing a basis for future studies.

Occurrence of foot diseases in cattle attended at the Clínica de Bovinos de Garanhuns: Epidemiological, clinical, therapeutic and economic aspects / Ocorrência de afecções podais em bovinos atendidos pela Clínica de Bovinos de Garanhuns: aspectos epidemiológicos, clínicos, terapêuticos e econômicos

The objective was to study the occurrence of foot disorders in cattle treated at the Clínica de Bovinos de Garanhuns, campus of the Universidade Federal Rural de Pernambuco from 1999 to 2021. A retrospective study of the medical records was carried out, with a total of 334 cases, in which 613 lesions were diagnosed. A frequency distribution, with simple mean and standard deviation was performed to evaluate the data. Interdigital dermatitis was more frequent in 12.4% (76/613), double sole in 9.79% (60/613), chronic laminitis in 8.81% (54/613), sole ulcer in 7.83% (48 /613), and interdigital hyperplasia in 7.24% (45/613). Laminitis and its consequences accounted for 45% of the total injuries identified, followed by 36% of injuries of secondary or uncertain cause, and 19% from infectious diseases. The distribution of lesions between the limbs was 68% in the pelvic and 32% in the thoracic limbs. Females, raised in a semi-intensive system, Holstein, with a body score of III, and large size were more affected. Lameness was present in 78% (260/334), while 10% (33/334) did not present lameness. The case fatality and recovery rates were 9% (31/334) and 73% (243/334), respectively. In total, 51% of cases occurred in the rainy season and 49% in the dry season. The main cities of origin were Bom Conselho 22.75% (76/334), Garanhuns 18.86% (63/334), and Brejão 12.57% (42/334). The estimated cost of treatment was US$ 150.13/case. Diseases are probably directly linked to management failure on the property due to the nature of the diagnosed diseases, in addition to the significant cost of the treatment of these animals, with the need for prophylactic measures in order to avoid the economic losses associated with foot diseases.

Objetivou-se estudar a ocorrência das afecções podais em bovinos atendidos na Clínica de Bovinos de Garanhuns, Campus da Universidade Federal Rural de Pernambuco, no intervalo de 1999 a 2021. Realizou-se estudo retrospectivo dos prontuários, com total 334 casos, dos quais foram diagnosticadas 613 lesões digitais. Foi realizada a distribuição de frequência, média simples e desvio padrão para avaliação dos dados. A dermatite interdigital foi a mais frequente, sendo observada em 12,4% (76/613) dos casos, seguida por sola dupla 9,79% (60/613), laminite crônica 8,81% (54/613), úlcera de sola 7,83% (48/613) e a hiperplasia interdigital 7,24% (45/613). A laminite e suas consequências representaram 45% do total de lesões identificadas, acompanhadas por 36% das injúrias de causa secundárias ou incertas e de doenças infecciosas com 19%. A distribuição das lesões entre os membros foi de 68% nos pélvicos e 32% nos torácicos. As fêmeas criadas em sistema semi-intensivo, holandesas, com escore corporal III e porte grande eram mais acometidas. A claudicação estava presente em 78% dos animais, enquanto 10% não claudicavam. As taxas de letalidade e recuperação foram de 9% (31/334) e 73 % (243/334), respectivamente. No período chuvoso foram 51% dos casos e 49% na época seca. Os principais municípios de origem foram Bom Conselho 22,75% (76/334), Garanhuns 18, 86% (63/334) e Brejão 12,57% (42/334). O custo estimado com tratamento foi de US$ 150,13/caso. Provavelmente falhas de manejo nas propriedades foram importantes fatores de risco para as doenças. Sugere-se a implementação de medidas profiláticas para evitar as perdas econômicas associadas às enfermidades podais.

Dermatitis seborreica en tapir albino (Tapirus terrestris) / Seborrheic dermatitis in albino lowland tapir (Tapirus terrestris) / DERMATITE SEBORREICA EM ANTA ALBINA (Tapirus terrestris)

El albinismo es una anomalía genética recesiva en la que la produccíon de la melanina está reducida o ausente, lo que interfiere com la  pigmentación de la piel, pelaje y los ojos de los individuos.

Albinism is a recessive genetic disorder in which melanin prodution is reduced or absent, interfering with pigmentation of the skin, hair and eyes of individuals. It is considered to be of rare natural occurrence, mainly in wild animals. Albino individuals are highly susceptible to skin damage caused by the sun, once cumulative exposure to ultraviolet (UV) rays can be harmful. This report discusses the occurrence of dry seborrhea in an albino lowland tapir (Tapirus terrestris), kept under human care. Dry seborrhea is a chronic skin disease in which there is a failure in the keratinization of the epidermis, forming excessive scales and altering the oiliness of the skin and hair. The clinical treatment instituted was based on topical application of a moisturizing dermatological spray solution and on changes made to the enclosure in order to reduce the incidence of sunlight on the individual. The result was satisfactory and had as na aid a portable digital microscope that was used periodically until the recovery of the animal.

Chronic progressive lymphoedema in a Friesian horse: clinical aspects and diagnostic approach - case report / [Linfedema progressivo crônico em um cavalo Friesian: aspectos clínicos e abordagem diagnóstica - relato de caso]

Chronic Progressive Lymphoedema (CPL) is a disabling disease of draft horses that affects lymphatic system function typically in the distal limbs. Deformities of distal limbs, especially of the pastern, with fibrosis and skin nodular lesions are consequences of disease progression. A 15-year-old Friesian stallion presented for evaluation with history of forelimb enlargement and nodule formations distal to the carpus for four years. Simple radiographs showed soft tissue nodular lesions and venous contrasted radiography showed intense enlargement of II common digital palmar vein of both forelimbs. Tissue culture tests revealed Streptococcus equi and Proteus mirabilis isolation and skin scraping test identified Chorioptes bovis mites. Histological examination revealed perivasculitis and lymph vessels distention. History, clinical and histological findings, and complementary exams suggested CPL diagnosis. We were unable to find previously published cases describing this disease in Brazil, where the increasing number of draft horses requires attention to this problem. The correct and early diagnosis substantially delays disease progression. Therefore, we highlight the need for nationwide propagation of these data to ensure better diagnosis and early treatment of future CPL cases.

O linfedema crônico progressivo (LCP) é uma enfermidade incapacitante de cavalos de tração que afeta o sistema linfático e se manifesta especialmente na região distal dos membros. A progressão da doença resulta em deformações na região distal dos membros, especialmente na quartela, com fibrose e lesões nodulares na pele. Foi atendido um garanhão da raça Friesian, de 15 anos de idade, com histórico de aumento de volume, nodulações e deformações na região distal dos membros torácicos, com início há aproximadamente quatro anos. Ao exame radiográfico simples, foram identificadas nodulações na pele e no subcutâneo e, ao exame venoso contrastado, identificou-se marcante dilatação II veia digital palmar comum em ambos os membros torácicos. Foi isolado Streptococcus equi e Proteus mirabilis ao cultivo tecidual e identificou-se sarna do tipo corióptica ao raspado de pele. No exame histopatológico, foram identificadas perivasculite e dilatação de vasos linfáticos. Os achados clínicos, histórico, de raça do animal e os exames complementares direcionaram o diagnóstico para o LCP. A pesquisa da literatura nacional não revelou descrições clínicas dessa enfermidade, mas, devido ao aumento do número de animais de tração no país nos últimos anos, a descrição dessa enfermidade se torna importante. O diagnóstico correto e precoce é necessário para retardar a progressão da doença. Nesse sentido, ressalta-se a relevância da divulgação nacional desses achados, a fim de contribuir para o diagnóstico precoce e permitir o retardo da evolução da doença.

Morphometry and skeletopy of kidneys and renal vessels in "ring-tailed coati" (Nasua nasua) / Morfometria e esqueletopia dos rins e vasos renais no "quati de cauda anelada" (Nasua nasua)

Nasua nasua is a carnivore belonging to the family Procyonidae and is widely distributed throughout South America. The details of its anatomy are fundamental to the application of antomy and understanding of its natural history. This study aimed to measure the average length, width, thickness, and volume of the kidneys; the average length of the renal artery and vein, and to describe the renal and vessel skeletopy in Nasua nasua. For this purpose, 32 kidneys and renal vessels of 16 cadaveric specimens (eight male and eight female) were dissected and measured using a digital caliper. Pearson's correlation coefficients were calculated between the rostrum-sacral length and the renal and vessel variables. The kidneys had a "bean-shaped" aspect with smooth surfaces and were unipapilate. On average, the N. nasua kidneys measured 30 × 16 × 13 mm, with no significant difference between the sexes. The average right renal artery (1.74 ± 0.67 cm) was longer than the left (1.26 ± 0.43 cm), and the right renal vein (1.22 ± 0.34 cm) was shorter than the left renal vein (1.82 ± 0.46 cm) (p < 0.05). One male animal (6.8%) presented with a double right renal vein as an anatomical variation. Both the right and left kidney cranial poles prevailed at the level of the L2 vertebra, assuming a practically symmetrical position. There was a positive and moderate to high correlation between rostrum-sacral length and renal dimensions and renal vessel lengths. The present data may be useful for interpreting the diagnosis of nephropathies that affect renal dimensions in this species and may contribute to the comparative anatomy of carnivorans.(AU)

Nasua nasua é um carnívoro da família Procyonidae amplamente distribuído pela América do Sul. Detalhes de sua anatomia são fundamentais para a anatomia aplicada e o entendimento de sua história natural. Objetivou-se determinar a média do comprimento, largura, espessura e volume elipsoide dos rins, a média do comprimento das artérias e veias renais e revelar a esqueletopia dos rins e vasos renais em N. nasua. Para este propósito, 32 rins e os vasos renais de 16 espécimes cadavéricos (oito machos e oito fêmeas) foram dissecados e mensurados com um paquímetro digital. Os coeficientes de correlação linear de Pearson foram calculados entre o comprimento rostro-sacral e as variáveis dos rins e seus vasos. Os rins apresentaram formato de "feijão" e superfícies lisas e são unipapilados. Na média, os rins de N. nasua mediram 30x16x13 mm, sem diferença significativa entre antímeros ou sexos. O comprimento médio da artéria renal direita (1,74 ± 0,67 cm) foi maior que o da esquerda (1,26 ± 0,43 cm); o comprimento da veia renal direita (1,22 ± 0,34 cm) foi menor que o da esquerda (1,82 ± 0,46 cm) (p < 0,05). Em um macho (6,8%), foi identificada uma veia renal direita dupla como variação anatômica. Os polos craniais dos rins direito e esquerdo prevaleceram ao nível da vértebra L2, assumindo praticamente uma posição simétrica. Houve uma correlação positiva, moderada a elevada, entre o comprimento rostro-sacral com as dimensões renais e com o comprimento dos vasos renais. Os dados do presente estudo poderão vir a ser aplicados na interpretação do diagnóstico de nefropatias que cursam com alterações nas dimensões renais bem como contribuir no campo da anatomia comparada de carnívoros.(AU)

Amputation of the front medial digit of a Holstein cow - successful parturition and milk production

Background: Diseases of the bovine digit and hoof remain major problems in dairy farming and the beef cow industry. Severe claudication accompanying swelling and pain at the lesion is often observed in deep digital sepsis, septic arthritis, severe sole ulcers, and chronic interdigital phlegmon. In addition, digital amputation is often performed in cases of white line disease or severe trauma, such as bone fractures. There are few reports of amputation of the medial digit of the bovine front hoof. In this case, amputation of the medial digit of the front leg of a pregnant cow was performed; its hospitalization and return to productivity is reported. Case: The bovine was a 9-year-old Holstein cow in the 6th month of pregnancy, weighing 671 kg. Upon admission, the cow could not bear weight on its right front leg, and swelling and a purulent discharge were observed in the coronary area of the medial digit. X-ray examination results indicated a periosteal reaction centered on the 3rd phalanx of the medial digit of its right front leg hoof and slight periosteal reactions at the adaxial sides of the middle and proximal phalanges, strongly suggestive of septic arthritis caused by infection. According to the X-ray examination results, no abnormalities of the lateral digit of the front right hoof were observed; thus, it was estimated that the post-amputation hoof would be able to bear weight. Therefore, a decision was made to perform immediate amputation of the medial digit of the right front leg hoof to reduce pain for improved delivery of the offspring and improved milk production during the lactation period, rather than allowing the lesion progress until the dry period or the expected date of delivery. According to the X-ray examination results, amputation of the 1st phalanx alone was expected to suffice for removal of the cause of the pain; thus, a decision was made to perform amputation at the edge adjacent to the 2nd phalanx. The right front medial digit was prepared for aseptic surgery, and infiltration anesthesia was performed. An incision was made with a surgical knife at the interdigit of the right front limb. A wire saw was inserted into the site to cut the 2nd phalanx in the anti-axial direction down to the skin to resect the lesion. White viscous pus was discharged at the resection site; therefore, the wound was lavaged with tap water and packed with povidone iodine-impregnated gauze. The wound was also covered with a diaper and dressed with non-elastic and elastic bandages. The dressing was changed daily to aid wound healing. No problems were observed in the standing-up motion or other relevant movements immediately after the surgery. Granulation tissue formed rapidly, approximately 2 weeks after the surgery, and the lesion dried gradually. Approximately one month after the surgery, the subject exhibited little difficulty in both standing up and walking. The subject successfully delivered its 7th offspring at the farm on postoperative day 93. Discussion: The animal of this study was a 9-year-old, pregnant cow, and although amputation of the front medial digit is a relatively rare procedure, the cow was able to deliver and return to production, owing to sufficient postoperative treatment and care. The case also demonstrated the advantage of X-ray examination in bovine hoof diseases for accurate diagnosis, precise operation, and prognostic assessment.

Eficácia dos tratamentos da pododermatite em aves

A pododermatite é uma inflamação podal que evolui para uma infecção por bactérias e fungos e acomete aves em ambiente cativo. O objetivo do tratamento da pododermatite é diminuir a inflamação/infecção, diminuir a pressão sobre o membro e remover o fator predisponente. Foram selecionados sete artigos. As terapias obtiveram regressão das lesões podais, porém nenhum artigo demonstrou a eficácia dos tratamentos, com embasamento científico, devido ao número restrito de animais utilizados. Portanto, para a determinação da eficácia dos tratamentos da pododermatite em aves seria necessária a realização de estudos clínicos randomizados e controlados. (AU)

Gaining body temperature in horses: mercury, digital and infrared thermometer in different locations / Aferição da temperatura corporal em equinos: avaliações de diferentes métodos e locais

The physical examination has several stages, one of which is the measurement of body temperature, when it exceeds the physiological values is indicative of some disease or hyperthermia, for this in veterinary medicine the mercury or digital thermometer is commonly used. The objective of this work is to compare if there is a difference between the mercury thermometer and the infrared thermometer or digital thermometer, as well as to identify if there is a difference between the measurement locations with the infrared thermometer and the mercury column thermometer and digital thermometer. Infrared temperature was evaluated in three places: oral mucosa, pinna and anal or vaginal mucosa (females), then a digital thermometer, followed by mercury, which was used as a reference standard. There was a statistical difference between the mercury thermometer and the infrared thermometer, when measured on the anal or vaginal mucosa and on the oral mucosa. The infrared thermometer, in the ear, and the digital thermometer did not differ from the mercury thermometer, demonstrating that these present similar values during the temperature measurement. The infrared thermometer proved to be little invasive and fast when compared to the others. However, some limitations were observed in the measurement of body temperature with the infrared thermometer measured in the ear.(AU)

O exame físico tem várias etapas, uma delas é a aferição da temperatura corporal, quando ultrapassa os valores fisio-lógicos é indicativo de alguma enfermidade ou hipertermia, para isso na medicina veterinária é comumente utilizado o termô-metro de mercúrio ou o digital. O objetivo desse trabalho é comparar se existe diferença entre o termômetro de mercúrio e o termômetro infravermelho ou termômetro digital, bem como identificar se existe diferença entre os locais de aferição com o termômetro infravermelho e o termômetro de coluna de mercúrio e termômetro digital. Realizava-se a avaliação da tempera-tura com o infravermelho, em três lugares: mucosa oral, pavilhão auricular e mucosa anal ou vaginal (fêmeas), depois termô-metro digital, seguido pelo de mercúrio que foi utilizado como padrão de referência. Observou-se diferença estatística entre o termômetro de mercúrio e o termômetro infravermelho, quando aferido na mucosa anal ou vaginal e na mucosa bucal. Já o termômetro infravermelho, no pavilhão auricular, e o digital não diferiram do termômetro de mercúrio, demonstrando que estes apresentam valores semelhantes durante a aferição de temperatura. O termômetro infravermelho se demonstrou pouco invasivo e rápido quando comparados aos demais. Entretanto foram observadas algumas limitações da mensuração da tempe-ratura corporal com o termômetro infravermelho aferido no pavilhão auricular. Conclui-se que o termômetro infravermelho, utilizado no pavilhão auricular, e o termômetro digital se equivalem ao termômetro de mercúrio e podem ser utilizados em equinos, porém ainda é preciso mais estudos sobre esse tema.(AU)

Outcome of a ceratohyiodectomy in a criollo mare with temporohyoid osteoarthropathy

Background: Temporohyoid osteoarthropathy (THO) is a progressive disease that causes acute onset of peripheral vestibular signs with or without facial paralysis. Ankylosis of temporhyoid joint occurs which predispose to fractures of theinvolved bones and consequently causes the commonly neurological signs observed. Clinical signs vary depending on thestage of the disease and the nerves affected. Surgical treatment is advised to improve survival rates in which the ceratohyoidectomy is currently known as the most advantageous. The aim of the present study is to report a case and outcome ofa ceratohyoidectomy procedure in a Criollo mare presenting THO of the right temporohyoid joint.Case: A 17-year-old Criollo mare was referred to the Equine Clinical Hospital of the Federal University of Pelotas witha 5-day history of facial paralysis on the right side, head tilt and difficulty to chew and swallow. Auricular, palpebraland labial ptosis along with deviation of the lip and nostril to the left were observed. A corneal ulcer was also identifiedin the right eye. Complementary imaging exams (endoscopy of the guttural pouches and radiography of the head) wereperformed and showed thickening of the right stylohyoid bone confirming a diagnosis of THO. Anti-inflammatory andantibiotic therapy were administered and the corneal ulcer was treated with topical antibiotics and autologous serum. Dueto rapid deterioration of clinical signs, the mare was referred to surgery. A ceratohyoidectomty procedure was performedunder general anesthesia. In this procedure, the ceratohyoid bone was disarticulated from the ceratohyoid-basihyoid jointand removed. During the procedure, a branch of the linguofacial vein was accidentally incised causing hemorrhage, thebranch was identified and successfully ligated. Recovery was uneventful. Supportive treatment with anti-inflammatory andantibiotics was continued after surgery and ...

Linfoma intravascular canino - aspectos clínicos, patológicos e imunohistoquímicos / Intravascular lymphoma in canine - clinical, pathological and immunohistochemical aspects

Background: Intravascular lymphoma (IL) is a rare disease characterized by presence of neoplastic lymphocytes in thelumen of blood vessels. Any tissue can be affected; however, the most frequently compromised areas of the body are theskin and the central nervous system (CNS). The clinical signs and macroscopic alterations caused by IL are nonspecific andare usually secondary to a continuous proliferative disorder, which leads to occlusion of the blood vessels with consequentthrombosis, hemorrhage and infarction. The objective of this work is to report a case of IL in a dog.Case: An 8-year-old male Rottweiler dog was referred to the Veterinary Hospital of the Federal University of Paraná witha history of cerebellar ataxia that had not improved after treatment. At the neurological examination, cerebellar ataxia anddeficit of nasal reflex were detected. A complete blood count showed presence of slight anemia (4.8 million red bloodcells/mm3; normal ranges= 5.5-8.5 million/mm3) and thrombocytopenia (176.000/mm3; normal ranges= 250.000-500.000/mm3). Biochemical tests revealed a small increase in alanine aminotransferase (42 IU/L; normal ranges= 14-38 IU/L) and aslight decrease in alkaline phosphatase (49 IU/L; normal ranges= 90-170 IU/L). The cerebrospinal fluid (CSF) exhibited anincreased protein concentration (147.3 mg/dL; normal ranges= 18-44 mg/dL) and pleocytosis (8 cells/µL; normal ranges=up to 5 cells/µL). No alterations were observed at radiographic and ultrasonographic exams. A clinical treatment was prescribed; however, in view of the worsening of the clinical signs, euthanasia was performed, and the body was submittedto a Laboratory of Pathology. At necropsy, moderate multifocal ulcers were observed in the oral cavity and ventral side ofthe tongue; moderately infarcted areas were detected in the spleen. Additional alterations such as fatty liver degeneration...

Ultrasonographic detection of interstitial nephritis in a canine fetus

Background: A detailed ultrasound examination of the fetal urinary tract as part of prenatal care is important to detect possibleabnormalities. Early diagnosis can prevent more serious damage such as loss of kidney function. Interstitial nephritis cancompromise renal functionality. Also, acute interstitial nephritis is a frequent cause of acute kidney injury and can becomechronic if not treated. Besides, a renal biopsy can help in the diagnosis and at the staging of the disease. Therefore, thisreport aims to describe the ultrasonographic findings of the renal tissues in a canine fetus affected by interstitial nephritis.Case: Gestational ultrasound evaluations were performed in a female Pug, at the 25th, 45th, and 58th gestational days.Ultrasound examination was performed with a 9.0 MHz linear transducer and a high-resolution digital transducer with afrequency standardized at 17.0 MHz. During the first evaluation, embryonic vesicles were detected and were compatible withthe gestational period. At 45 days of gestation, some abnormalities were observed in the kidneys of one of the fetuses, suchas increased cortical echogenicity, cortical thickening, loss of corticomedullary ratio (1:1), renal pelvis and ureter dilatationby echogenic content. Biparietal and abdominal diameters were also lower than that from the other fetuses, which did notshow abnormalities, being compatible with the estimated gestational age. However, the heart rate was similar among allfetuses. On the 58th day, we observed in the underdeveloped fetus that both kidneys still presented the abnormalities seenpreviously, in addition to the presence of a cystic structure in the right kidney, in the cranial...
