Effects of ketamine, midazolam and methadone, combined with local anesthesia, in cats undergoing orchiectomy / Efeitos da cetamina, midazolam e metadona, associados à anestesia local, em gatos submetidos à orquiectomia

Different anesthetic combinations are used for orchiectomy in cats. This study aimed to evaluate the anesthetic and cardiopulmonary effects on the physiological variables of ketamine (10 mg/kg), midazolam (0.2 mg/kg) and methadone (0.3 mg/kg), combined with local anesthesia, in cats undergoing orchiectomy (n = 19 cats). The time for lateral recumbency, degree of sedation, muscle relaxation and nociception were recorded preoperatively. The propofol rescue dose was recorded. The time to head up and quality of recovery were evaluated postoperatively. The time for lateral recumbency was 5 ± 2 minu-tes. Fifteen minutes after the administration of the ketamine-midazolam-methadone combination, a greater sedative effect, muscle relaxation and less response to noxious stimulation were observed. Propofol was administered to twelve cats under local anesthesia, at a total dose of 1.5 ± 0.8 mg/kg. Surgery was started 28 ± 5 minutes after the administration of ketamine--midazolam-methadone combination. There were no differences in the physiological variables evaluated over the other evalu-ation times (p > 0.05). The recovery quality scores were adequate, and the time to head up was 51 ± 10 minutes. Under the conditions of this study, the ketamine-midazolam-methadone combination did not allow local anesthesia for orchiectomy. Many cats required propofol rescue prior to surgery. This combination promoted minimal changes in physiological variables and prolonged anesthetic recovery.(AU)

Diferentes combinações anestésicas são usadas para orquiectomia em gatos. O objetivo deste estudo foi avaliar o efeito anestésico e as alterações promovidas nas variáveis fisiológicas pela cetamina (10 mg/kg), midazolam (0.2 mg/kg) e metadona (0.3 mg/kg), combinados com anestesia local, em gatos submetidos à orquiectomia (n = 19 gatos). O tempo para adoção do decúbito lateral, grau de sedação, relaxamento muscular e nocicepção foram registrados no pré-operatório. A dose de resgate de propofol foi registrada. O tempo para o gato erguer a cabeça e a qualidade da recuperação foram avaliados no pós-operatório. O tempo para adoção do decúbito lateral foi de 5 ± 2 minutos. Quinze minutos após a administração da associação cetamina-midazolam-metadona, observou-se maior efeito sedativo e relaxamento muscular, e menor resposta à estimulação nociva. O propofol foi administrado em doze gatos para realização de anestesia local, utilizando a dose total de 1.5 ± 0.8 mg/kg. A cirurgia foi iniciada 28 ± 5 minutos após a administração de cetamina-midazolam-metadona. Não houve diferença nas variáveis fisiológicas avaliadas em relação aos demais tempos de avaliação (p > 0.05). Os escores de qualidade de recuperação foram adequados e o tempo para o gato erguer a cabeça foi de 51 ± 10 minutos. Nas condições deste estudo, cetamina-midazolam-metadona não permitiu a realização da anestesia local para orquiectomia. Muitos gatos precisaram de resgate com propofol antes de iniciar a cirurgia. Essa associação promoveu alterações mínimas nas variáveis fisiológicas e longa recuperação anestésica.(AU)

Estabilização de ombro em um gato ­ Relato de caso / Shoulder estabilization in a cat ­ Case report

A estabilidade da articulação do ombro é garantida por ligamentos, cápsula articular, tendões e músculos, contudo traumas podem causar falência dos mecanismos estabilizadores, com consequente luxação ou instabilidade articular. Objetivou-se relatar o caso de instabilidade medial e lateral de ombro direito em felino sem raça definida, atendido com queixa de claudicação aguda de membro torácico secundária a trauma por confronto com outro animal. Inicialmente foi realizado tratamento clínico por meio de imobilização articular. Contudo, devido ao insucesso da técnica, procedeu-se para o tratamento cirúrgico de estabilização articular com prótese ligamentar sintética. No pós-operatório imediato, evidenciou-se ausência de crepitações e instabilidade articular. Após oito dias da cirurgia, o paciente apresentou retorno total às funções de apoio do membro e sem sinais de dor ou redução de movimentos. Concluiu-se que, embora de reduzida ocorrência, a instabilidade de origem traumática do ombro configura-se como um diferencial para claudicação aguda de membro torácico e que o tratamento cirúrgico pode ser necessário, mostrando-se eficiente na resolução de tais casos com o acesso e técnica de estabilização propostos.

The stability of the shoulder joint is granted by ligaments, joint capsule, tendons and muscles. However, traumatic injuries can cause failure of the stabilization mechanisms, which leads to articular luxation or instability. The aim of the paper is to report a case of medial and lateral right shoulder joint instability in a mixed-breed cat, presenting acute forelimb lameness after a fight trauma with another cat. Initially, it was recommended a conservative treatment through articular immobilization. However, the technique was unsuccessful, and the surgery treatment was performed, to stabilize the joint with synthetic ligament prosthetic. In the postoperative period, no crepitation or instability were identified. After eight days of surgery, the patient returned totally to the normal function of the forelimb, without movement restriction or pain. It was concluded that, although rare, the traumatic shoulder joint instability is a differential diagnosis for acute forelimb lameness and the surgical treatment can be necessary, showing a good result in the resolution of these injuries with the surgical approach and stabilization method proposed.

Acquired skin fragility syndrome in a juvenile cat following a routine ovariohysterectomy

Background: Acquired skin fragility syndrome (ASFS) is a rare condition, which is characterized by spontaneous fragility of the skin and an absence of hyperextensibility. Even though the real pathogenesis of ASFS remains unknown that isreported generally with some iatrogenic causes and severe diseases. Thus, based on the clinical findings this is the firstreport of describes the case and treatment of feline acquired skin fragility syndrome following a routine ovariohysterectomy.Case: An 8-month-old domestic shorthair female cat was brought to the Siirt University Animal Health Application andResearch Center for ovariohysterectomy operation. Before the operation physical examination of the animal revealed bodytemperature, heart rate, respiratory rate, the color of mucosas, and lymph nodes were determined normally. Besides, thereis no hematological and biochemical problem detected. The cat had no previous history of several infections or systemicdisease. A routine ovariohysterectomy procedure was applied under general anesthesia and the cat was discharged onthe same day. Three days after that a spontaneously developed cutaneous laceration below the left scapular region wasdetermined by the cat owner. During the clinical examination, it was determined that the cat was sensitive to touch againstthe left scapular area. Multiple spontaneous skin tear was revealed over the left scapular region while shaving for betterinspection but did not obtain any problem with incision line. To identify the underlying cause of skin tearing, hematological and biochemical tests were done but the animal’s results were found within the normal references. Also, rapid bloodtests were performed for feline leukemia virus and immunodeficiency virus, and none of them were positive. Additionally,the skin was not hyperextensible.

Mandibulectomia em felino com osteomielite fibrosante bacteriana / Mandibulectomy in feline with bacterial fibrosing osteomyelitis

Background: Fibrosing osteomyelitis is a chronic inflammatory process caused by infectious agents that lead to the destructionand replacement of bone tissue by fibroblasts. The diagnosis is based especially on histopathological and bacterial culture. Incases where extensive and irreversible injuries are observed, surgical treatment may be indicated. The objective of this work isto report the clinical, radiographic, histopathological, and microbiological aspects of a cat presenting fibrosing osteomyelitis.Case: A 10-year-old male feline, no defined breed, weighing 3.9 kg was referred to one Private Veterinary Clinic of Fortaleza,CE, Brazil with a history of left mandibular enlargement, presenting dysphagia, sialorrhea, an increase in firm consistencyalong of the left mandibular body, temporomandibular arthralgia and decreased joint motion range. On cranium radiograph,signs of proliferative osteopathy of irregular contours were observed in the branch and body of the left mandible and extending to the rostral region of the right mandible, suggesting a neoplastic process. After anesthesia, for better assessment ofthe oral cavity, a sample was collected by incisional biopsy, however, the histopathological result was nonspecific. In viewof the inconclusive condition, it was decided to perform left hemimandibulectomy combined with right partial mandibulectomy. Tissue samples were obtained and sent for microbiological and histopathological analyses. The last test revealedan inflammatory reaction consisting of neutrophils and plasma cells, associated with a large amount of fibrous connectivetissue, multifocal bacterial aggregates, necrosis and bone resorption. Based on the findings, the diagnosis of chronic bacterial osteomyelitis was concluded. The microbiological culture demonstrated the growth of the bacterium Pseudomonasaeruginosa, with sensitivity to cefovecin, which was administered to the treatment in....

Reparo de ruptura crônica do ligamento patelar em um felino / Repair of chronic patelar ligament rupture in a cat

Relata-se o caso de uma felina, sem raça definida, de oito meses de idade e 3,6 kg, com queixa de impotência funcional completa do membro pélvico esquerdo após trauma. A paciente apresentava aumento de volume em região do joelho, dor à palpação e instabilidade patelar. O diagnóstico de ruptura do ligamento patelar foi realizado com base nos resultados do exame ortopédico, juntamente com exame radiográfico e ultrassonográfico do joelho. O método utilizado para reparo da lesão foi a sutura em oito com fio de tetrafluorcabono associado à sutura interrompida simples para aproximação das bordas do ligamento. Durante a reavaliação de trinta dias pós-operatório, a paciente já apresentava melhora significativa, com atividade funcional completa do membro e ausência de dor.

We report the case of an eight-month-old, 3.6 kg, crossbred feline, complaining of complete functional impotence of the left pelvic limb after trauma. The patient presented swelling in the knee region, pain on palpation and patellar instability. The diagnosis of patellar ligament rupture was based on the results of the orthopedic examination, together with radiographic and ultrasound examinations of the knee. The method used to repair the lesion was eight-point suture with tetrafluorocabono thread associated with simple interrupted suture for approximation of the ligament edges. During the thirty-day postoperative reassessment, the patient already presented significant improvement, with complete functional activity of the limb. and absence of pain.

Mammary fibroepithelial hyperplasia in a male cat

Background: Feline mammary hyperplasia (FMH) is a benign disease that commonly affects young females, once it iscaused by the exaggerated stimulation of endogenous or exogenous progestogen. FMH leads to acute edema and inflammation of the mammary glands and frequently evolve to ulcerations, secondary infections, and systemic clinical signs.Even though it is rare in male cats, progesterone therapy or an unknown endogenous source of hormone can cause thedisease. This report aims to describe a case of FMH in a male feline with no history of hormonal treatment and treatedwith radical surgical resection.Case: A 7-month-old intact male domestic shorthair cat was presented due to acute onset of generalized mammary tumorswhich had progressed for 18 days. Tumors size had 5 cm large in diameter, symmetric, bilateral, and affected all mammaryglands. The tissue was firm, hyperemic, and ulcerated. FMH was initially suspected but with a differential diagnosis formammary adenocarcinoma. Except for pain on tumor palpation, there was no other clinical abnormality. Survey thoracicradiographs and abdominal ultrasound did not find signs of metastasis or hermaphroditism. Fine-needle aspirate biopsy andfurther cytological examination were inconclusive. Surgical resection through a single-stage bilateral total mastectomy andreconstruction using a left flank fold flap was elected. There were no intraoperative complications and the cat recoveredwell, with good healing and no clinical signs 21 days after the surgery. Histological examination of the mammary glandsconfirmed the diagnosis of FMH due to the non-neoplastic characteristics and tissue’s benign biological behavior. Elevenmonths after diagnosis, the cat was asymptomatic.Discussion: The FMH frequently affects young females and is associated with gestational periods, the end of the estrouscycle, and, most commonly, hormonal therapy with synthetic progesterone. Male cats are rarely affected with or...

Eversão da cartilagem da terceira pálpebra em um gato / Eversion of the third eyelid cartilage in a cat

Background: Eversion of the cartilage of the third eyelid is a rare congenital disease in cats. It is caused by the anterioreversion of the cartilage edge of the third eyelid. Clinical signs may be associated with secondary keratoconjunctivitis,third eyelid gland protrusion, and ocular surface irritation. The diagnosis is made by ophthalmic examination, and treatment consists of surgical resection of the everted cartilage portion. The goal of the present study was to report a case ofeversion of third eyelid cartilage in a cat, given that it is an unusual abnormality in this animal species, and an importantdifferential diagnosis to be considered in the disorders of the third eyelid.Case: A 6-year-old neutered female Persian cat was presented with a presumptive diagnosis of protrusion of the thirdeyelid gland, history of ocular irritation, and epiphora in the left eye. The disorder had been intermittently present sincethe animal was 1-year-old, with spontaneous disappearance after approximately 15 days. The owner related the reappearance of the disorder to stressful situations, with no previous history of trauma or other ocular alteration. During theophthalmic examination, suspended solute was observed through biomiscroscopic examination in both eyes, as well asan increase in volume of the third eyelid in the left eye, without other changes. A thorough examination, under generalanesthesia, indicated the protruding volume of the cartilage of the everted third eyelid. The third eyelid was pleated inits upper portion, demonstrating that the cartilage of the third eyelid was folded instead of following the curvature of theocular surface. Under general anesthesia, the cartilage was partially removed through two parallel incisions on the bulbarconjunctival surface, divulsioning 5 mm in length in the vertical portion of the cartilage in a ‘T’ shape, and separating the...

Castração pré-púbere e suas consequências: revisão de literatura / Early neutering and its consequences: literature review

A cirurgia de castração é uma das técnicas cirúrgicas mais realizadas na rotina veterinária e a idade ideal para a sua execução ainda é contraditória entre os médicos-veterinários, uma vez que são escassos os estudos sobre este tema relacionados a alguns fatores, como raça e espécie. A castração é tida como método de contracepção, controle de zoonoses e método preventivo e terapêutico de algumas enfermidades como as afecções do sistema reprodutor. A castração pré-púbere é amplamente aplicada em diversos países, porém certas consequências desta prática, como o aumento do risco de aparecimento de algumas enfermidades como afecções urogenitais, obesidade, diabetes mellitus, afecções musculoesqueléticas e neoplasmas têm sido levantadas. Assim sendo, esta revisão de literatura pretende abordar a castração pré-púbere e suas consequências com o objetivo de contribuir para a tomada de decisão dos profissionais veterinários e de contribuir para a realização de estudos futuros.

Castration surgery is one of the most commonly performed surgical techniques in the veterinary routine, and the optimal age for its execution is still contradictory among veterinarians. Castration is considered a method of contraception, control of zoonoses and a preventive and therapeutic method for some diseases such as diseases of the reproductive tract. Early neutering is widely applied in several countries, but certain consequences of this practice, such as the increased risk of some diseases such as urogenital disorders, obesity, diabetes mellitus, musculoskeletal disorders and neoplasms must be considered. Therefore, this paper is a review of early neutering of dogs and cats and its consequences, in order to contribute to the decision-making of veterinary professionals, and collaborating with future studies.

Resolução cirúrgica de pólipo inflamatório em ouvido médio de felino através da técnica de avulsão e tração por abordagem lateral: relato de caso / Surgical resolution of feline middle ear inflammatory polyp by lateral approach traction and avulsion technique: case report

O objetivo desse trabalho foi descrever um caso de pólipo inflamatório em ouvido médio de um felino e sua resolução cirúrgica através da avulsão e tração da massa após abordagem lateral. Um felino, fêmea, de 2 anos de idade, foi atendido no Hospital Veterinário Professor Sylvio Barbosa Cardoso, apresentando prurido intenso, dor e secreção fétida em região auricular. Pelo exame físico foi possível observar um nódulo em região de ouvido médio esquerdo. Associado a isso, o animal apresentava "headtilt" (inclinação da cabeça para o lado afetado). Foram solicitados exames hematológicos, radiografia de crânio e citologia da massa. O animal foi encaminhado para cirurgia de extirpação da massa. Foi feita uma incisão na pele sob o canal auditivo vertical palpável. A cartilagem foi liberada até o nível da junção entre as cartilagens auricular e anular. Com o auxílio de um fórceps, o pólipo foi agarrado e delicadamente girado até ser completamente extirpado de sua origem. A cartilagem e o subcutâneo foram fechados com material de sutura monofilamentar 4-0 e a pele foi fechada em um padrão de sutura subdérmica usando o mesmo material. A peça foi encaminhada para exame histopatológico, pelo qual confirmou-se a suspeita de pólipo inflamatório, através da observação de epitélio colunar ciliado. Utilizando a técnica cirúrgica TALA (avulsão e tração após abordagem lateral) foi possível obter melhora do quadro clínico do animal referido, rápida recuperação pós-cirúrgica e sem nenhuma complicação decorrente da técnica. Essa técnica, portanto, se mostrou satisfatória, melhorando significativamente a qualidade de vida do animal.

The aim of this study was to describe a case of inflammatory polyp in the middle ear of a cat and its surgical resolution through avulsion and mass traction after lateral approach. A female feline, two year old, was admitted at the Hospital Veterinário Professor Sylvio Barbosa Cardoso, presenting intense itching, pain and fetid discharge in the ear region. Physical examination revealed a nodule in the left middle ear region. Associated with this, the animal presented head tilt (inclination of the head to the affected side). Hematological examinations, skull radiography and mass cytology were requested. The animal was referred for polyp removal surgery. A skin incision was made under the palpable vertical ear canal. The cartilage was released to the level of the junction between the auricular and annular cartilages. With the help of a forceps, the polyp was grasped and gently rotated until completely removed from its origin. The cartilage and subcutaneous tissue were closed with 4-0 monofilament suture material and the skin was closed in a subdermal suture pattern using the same material. The piece was referred for histopathological examination, which confirmed the suspicion of inflammatory polyp by observing ciliated columnar epithelium. Using the TALA surgical technique (avulsion and traction after lateral approach) it was possible to obtain improvement of the clinical 3 picture of the referred animal, rapid postoperative recovery and without any complications resulting from the technique. This technique therefore proves satisfying, significantly improving the quality of life of the animal.

Use of a morcellized fragment of bone as a bone graft in a femoral fracture repair / Uso de fragmento ósseo morcelizado como enxerto ósseo no reparo de fratura femoral

As one of the most frequent reasons for presentation at the orthopedic services in veterinary practice, long bone fractures need bone continuity for consolidation to take place. This case report has demonstrates the use of a morcellized fragment of bone as a bone graft in a femoral fracture with major bone loss. A mixed-breed adult cat with a segmental femoral fracture with a large longitudinal fissure in the central bone fragment was submitted to an interlocking nail osteosynthesis. During the procedure a fracture occurred along the fissure resulting in two bone fragments with significant bone loss. Fragments were morcellized and applied over the defect to act as a bone graft. By the 15th day after the surgery, the cat had a normal gait and showed no pain response, and bone consolidation occurred after 7 months. Once harvesting of humeral, femoral and tibial bone grafts can be frustrating in cats, resulting in just small amounts of bone, the morcellation of the central fragments was vital to provide sufficient graft to cover the big defect in the femoral shaft. The authors suggest that autologous fresh morcellized cortical bone fragments can be an adjunct to the treatment of comminuted fractures in cats, as an alternative to more traditional repairs of comminuted fracture.

Fraturas de ossos longos necessitam de continuidade óssea para que a consolidação ocorra. Este relato de caso tem como objetivo demonstrar o uso de um fragmento ósseo morcelizado com a função de enxerto ósseo em uma fratura de fêmur com presença de uma grande falha óssea entre os fragmentos. Um gato adulto, sem raça definida, com uma fratura múltipla em fêmur com presença de uma fissura longitudinal no fragmento central foi submetido à osteossíntese com uso de haste bloqueada. Durante o processo, ocorreu uma fragmentação a partir da fissura, o que resultou na presença de dois fragmentos ósseos com uma grande porção de perda óssea entre os dois. Os fragmentos ósseos restantes do fragmento central foram morcelizados e aplicados no defeito para atuar com enxerto ósseo. Quinze dias após a cirurgia o paciente apresentou apoio normal e ausência de dor, e consolidação óssea ocorreu em 7 meses pós operatórios. Uma vez que a coleta de enxerto nos gatos resulta em pouca quantidade de osso, a morcelização do fragmento central foi vital para promover enxerto suficiente para cobrir o defeito ósseo. Os autores sugerem que o uso de enxerto cortical autólogo fresco morcelizado pode ser um adjuvante no tratamento de fraturas cominutivas em gatos, como um tratamento alternativo à terapia convencional.

Flap bipedicular no tratamento de lesão cutânea traumática em membro torácico de gato: relato de caso / Bipedicular flap in the treatment of traumatic skin injury in cat thoracic member: case report

O objetivo do presente estudo é relatar a construção de um retalho direto de bolsa bipediculada com fixação apendicular à região torácica para o tratamento de lesões extensas no membro torácico direito de um gato. Foi tratado no Hospital Veterinário Unicesumar Maringá - Paraná, um felino de 1 ano de idade, apresentando lesão no membro torácico, após história de briga com outro animal da mesma espécie. Ao exame físico, apresentava fístula e edema no membro torácico direito. O paciente foi anestesiado e foi realizado o desbridamento das áreas desvitalizadas. Como terapia inicial, a lesão foi tratada como ferida aberta, até a formação de tecido de granulação, para posterior correção do defeito empregando retalho bipediculado em bolsa direta, com fixação temporária do membro à parede torácica. Após duas semanas, o membro foi desimplantado e os pontos foram removidos 21 dias após a aplicação do retalho. O uso do retalho permitiu completa cicatrização da ferida, sem ocorrência de hematomas, necrose ou deiscência de sutura. Conclui-se que a utilização do retalho bipedicular é aplicável ao tratamento de feridas traumáticas em membro torácico de felinos.

The aim of the present study is to report the construction of a direct bipedicled pouch flap with appendicular fixation to the thoracic region for the treatment of extensive lesions in the right thoracic limb of a cat. He was treated on Hospital Veterinário Unicesumar Maringá - Paraná, a 1-year-old feline, presenting injury to the thoracic limb after a history of fighting with another animal of the same species. On physical examination, he presented fistula and edema in the right thoracic limb. The patient was anesthetized and debridement of the devitalized areas was performed. As an initial therapy, the lesion was treated as an open wound until granulation tissue was formed for subsequent correction of the defect using a direct pouch bipedicled flap, with temporary fixation of the limb to the chest wall. After two weeks, the limb was unimplanted and the stitches were removed 21 days after flap application. The use of the flap allowed complete wound healing without bruising, necrosis or suture dehiscence. It is concluded that the use of bipedicular flap is applicable to the treatment of traumatic wounds in feline thoracic limb.

The aim of this study was to describe a case of inflammatory polyp in the middle ear of a cat and its surgical resolution through avulsion and mass traction after lateral approach. A female feline, two year old, was admitted at the Hospital Veterinário Professor Sylvio Barbosa Cardoso, presenting intense itching, pain and fetid discharge in the ear region. Physical examination revealed a nodule in the left middle ear region. Associated with this, the animal presented head tilt (inclination of the head to the affected side). Hematological examinations, skull radiography and mass cytology were requested. The animal was referred for polyp removal surgery. A skin incision was made under the palpable vertical ear canal. The cartilage was released to the level of the junction between the auricular and annular cartilages. With the help of a forceps, the polyp was grasped and gently rotated until completely removed from its origin. The cartilage and subcutaneous tissue were closed with 4-0 monofilament suture material and the skin was closed in a subdermal suture pattern using the same material. The piece was referred for histopathological examination, which confirmed the suspicion of inflammatory polyp by observing ciliated columnar epithelium. Using the TALA surgical technique (avulsion and traction after lateral approach) it was possible to obtain improvement of the clinical 3 picture of the referred animal, rapid postoperative recovery and without any complications resulting from the technique. This technique therefore proves satisfying, significantly improving the quality of life of the animal(AU)

Resolução cirúrgica de pólipo inflamatório em ouvido médio de felino através da técnica de avulsão e tração por abordagem lateral: relato de caso / Surgical resolution of feline middle ear inflammatory polyp by lateral approach traction and avulsion technique: case report

O objetivo desse trabalho foi descrever um caso de pólipo inflamatório em ouvido médio de um felino e sua resolução cirúrgica através da avulsão e tração da massa após abordagem lateral. Um felino, fêmea, de 2 anos de idade, foi atendido no Hospital Veterinário Professor Sylvio Barbosa Cardoso, apresentando prurido intenso, dor e secreção fétida em região auricular. Pelo exame físico foi possível observar um nódulo em região de ouvido médio esquerdo. Associado a isso, o animal apresentava “headtilt” (inclinação da cabeça para o lado afetado). Foram solicitados exames hematológicos, radiografia de crânio e citologia da massa. O animal foi encaminhado para cirurgia de extirpação da massa. Foi feita uma incisão na pele sob o canal auditivo vertical palpável. A cartilagem foi liberada até o nível da junção entre as cartilagens auricular e anular. Com o auxílio de um fórceps, o pólipo foi agarrado e delicadamente girado até ser completamente extirpado de sua origem. A cartilagem e o subcutâneo foram fechados com material de sutura monofilamentar 4-0 e a pele foi fechada em um padrão de sutura subdérmica usando o mesmo material. A peça foi encaminhada para exame histopatológico, pelo qual confirmou-se a suspeita de pólipo inflamatório, através da observação de epitélio colunar ciliado. Utilizando a técnica cirúrgica TALA (avulsão e tração após abordagem lateral) foi possível obter melhora do quadro clínico do animal referido, rápida recuperação pós-cirúrgica e sem nenhuma complicação decorrente da técnica.

Trabecular trichoblastoma in a domestic cat (Felis catus domesticus, Linnaeus 1758) / Tricoblastoma trabecular em gato doméstico (Felis catus domesticus, Linnaeus 1758)

Trichoblastoma is characterized as a benign cutaneous neoplasm that originates in the trichoblastic epithelium of the hair bulb. The present report describes the case of a 4-year-old cross breed neutered male cat that had a history of a slow, freely movable, ulcerated, slow growing, solitary cutaneous nodule located on the left scapular region. Histopathological evaluation showed neoplastic cells arranged in cohesive nests or palisades with eosinophilic and scant cytoplasm. Based on the microscopic findings, a diagnosis of trabecular trichoblastoma was made. The treatment of choice consisted of total surgical excision of the mass with safe surgical margins. Tumor recurrence was not observed.(AU)

O Tricoblastoma se caracteriza como uma neoplasia benigna cutânea que tem origem no epitélio tricoblástico do bulbo piloso. O presente relato descreve o caso de felino macho, sem raça definida (SRD), com histórico de nódulo solitário de crescimento lento, não aderido e ulcerado, localizado na região escapular esquerda. A histopatologia evidenciou células neoplásicas organizadas em ninhos coesos, em paliçadas com citoplasma eosinofílico e escasso, os achados foram compatíveis com a descrição de tricoblastoma trabecular. O tratamento de eleição consistiu na exérese cirúrgica total da massa com ampla margem de segurança e recidivas não foram observadas.(AU)

Caracterização clínica e histopatológica de bulbos oculares de cães e gatos (2005-2015) / Clinical and histopathologic characterization of ocular bulbs in dogs and cats (2005-2015)

Objetivou-se realizar a caracterização clínica e histopatológica de bulbos oculares de cães e gatos, removidos cirurgicamente por indicação clínica, no período entre 2005-2015. Foram realizados 101 procedimentos de remoção do bulbo ocular, 93 enucleações (92%) e 8 exenterações (8%). Os procedimentos foram realizados em 80 cães, (79% dos casos) e em 21 gatos (21% dos casos). Os cães submetidos à intervenção cirúrgica apresentavam perfurações oculares (n=31, 39%), glaucoma (n=19, 24%), protrusão ocular (n=13, 16%), diagnósticos sugestivos de neoplasia (n=10, 12,5%) e outros (n=3, 2,97%). Dentre os gatos os diagnósticos clínicos compreenderam perfuração ocular (n=9, 49%), glaucoma (n=3, 14,2%), microftalmia (n=3, 14,2%), sugestivo de neoplasia (n=2, 9,5%), protrusão ocular (n=2, 9,5%) e outros (n=2, 9,5%). Vinte e sete amostras de bulbos oculares foram submetidas para avaliação histopatológica, sendo 23 provenientes de cães e quatro de gatos. Dentre as amostras de origem canina, sete exibiram achados histopatológicos compatíveis com glaucoma, sete perfurações oculares, seis neoplasias intraoculares, duas panoftalmites e um quadro de Phthisis bulbi. Nos bulbos oculares de gatos foram diagnosticadas duas neoplasias intraoculares, uma microftalmia e uma perfuração ocular. Constatou-se que o glaucoma secundário, as neoplasias e as perfurações oculares estão entre as principais causas de enucleação em cães, e associadas a alterações primárias como a ceratoconjuntivite seca e as uveítes. Estas afecções, diferentemente das neoplasias, podem ter êxito terapêutico mediante diagnóstico e tratamento precoces, prevenindo a cegueira e a remoção do bulbo ocular.(AU)

This study aimed to carry out the clinical and histopathologic characterization of ocular bulbs from dogs and cats, surgical removed as clinical indication between 2005-2015. Hundred-one procedures were performed, 93 enucleations (92%) and 8 exenterantions (8%). The procedures were performed on 80 dogs (79% of cases) and 21 cats (21% of cases). The dogs underwent to surgery had ocular perfuration (n=31, 39%), glaucoma (n=19, 24%), ocular protrusion (n=13, 16%), diagnosis suggestive of neoplasia (n=10, 12, 5%) and other (n=3, 2.97%). Among the clinical diagnosis cats comprise ocular perforation (n=9, 49%), glaucoma (n=3, 14.2%), microphthalmia (n=3, 14.2%), suggestive of neoplasia (n=2, 9.5%), ocular protrusion (n=2, 9.5%) and other (n=2, 9.5%). Twenty-seven samples of ocular bulbs were sent for histopathologic evaluation in Veterinary Pathology Laboratory, being 23 from dogs and four cats. Among the samples of dogs, seven exhibited histopathologic findings compatible with glaucoma, seven ocular perforations, six had intraocular neoplasias, two panoftalmites and condition of Phthisis bulbi. The ocular bulbs of cats received the diagnosis of two intraocular neoplasias, one microphthalmia and ocular perforation. It was found that the secondary glaucoma and ocular perforations are among the leading causes of enucleation in dogs, and associated with primary disorders such as keratoconjunctivitis sicca and uveitis. These disorders, unlike neoplasia, may have therapeutic success through early diagnosis and treatment, preventing blindness and removal of the eyeball.(AU)
