Background: Primary pulmonary neoplasia is rare in domestic cats, with fewer than 1% of all tumors diagnosed in thisspecies. Primary lung tumors have a high percentage of metastases, observed in up to 75% of cases in cats. The lung-digitsyndrome is characterized by primary pulmonary neoplasms with metastases to the extremities of the limbs, mainly distalphalanges, possibly involving several digits and more than one limb. This report describes a case of pulmonary carcinomametastasis in a cat digit.Case: A 16-year-old neutered female cat was showing increased volume of the fourth digit was examined at the Universityof Caxias do Sul veterinary clinic. The animal also showed signs of progressive weight loss, apathy and limping on theright thoracic limb. After clinical evaluation, the animal was sent for radiographic examination of the right metacarpal/phalangeal region and the thorax. A radiopaque structure was observed with discreet central regions of radiolucency,measuring approximately 3 cm in height, 3.4 cm in length and 2.4 cm in depth in the left caudal lung, suggesting neoplasiaor pulmonary abscess. Digit image revealed osteolysis of the right and middle distal phalanx measuring 2 cm in height, 3cm in breadth and 1 cm in length. In view of these radiographic changes, we performed fine needle aspiration cytology ofthe digit and a nodule in the region of the skeletal musculature of the right thoracic limb. Cytological evaluation revealedcells had cilia on their surface (compatible with respiratory epithelium). The cytologic findings of the fine-needle biopsywere suggestive of carcinoma. After stabilization, the digit was amputated. The material was sent to the laboratory of theFederal University of Pelotas for histopathological examination...

The goal of this study was to describe the normal values of corneal endothelial cell density and hexagonality in healthy rabbits eyes using contact specular microscopy. Both eyes of 18 rabbits, males and females, of different ages were evaluated. The eyes were divided into three groups of 12 each according to the age range of the animals: G1 (6 months old), G2 (12 months old), and G3 (48 months old). Parameters studied included mean endothelial cell density and hexagonality. For Group I, the mean cell density was 2307 cells per mm2. For GII, the mean cell density was 1895 cells per mm2. For G III, the mean cell density was 1818 cells per mm2. Cell density decreased significantly with aging (P 0.001) among the three groups. Pleomorphism in the rabbits of GI was 74.33±10.08. In the rabbits of GII it was 71.83±11.38. In the rabbits of GIII it was 64.02±28.80. Significant differences (P 0.001) were evident between GI and GIII and GII and GIII but not between Groups I and II. The results showed a decrease in number of cells and hexagonality with aging. Corneal endothelium of rabbits suffers changes due to advancing age both in terms of cell density and morphology.
Objetivou-se avaliar a densidade celular e a hexagonalidade do endotélio da cَrnea de coelhos saudلveis usando um microscَpio especular de contato. Os dois olhos de 18 coelhos, machos ou fêmeas, de diferentes idades foram avaliados. Os olhos foram separados em três grupos de 12 olhos cada em funçمo da idade: G1 (6 meses de idade), G2 (12 meses de idade) e G3 (48 meses de idade). Os parâmetros estudados incluيram a densidade celular e a hexagonalidade. Para o Grupo I, a densidade celular média foi de 2307 células por mm2. Para GII, a densidade celular média foi de 1895 células por mm2. Para G III, a densidade celular média foi de 1818 células por mm2. A densidade celular diminuiu significativamente com o envelhecimento (P 0,001) entre os três grupos. O pleomorfismo nos coelhos de GI foi de 74,33±10,08. Nos coelhos do GII foi 71,83±11,38. Nos coelhos de GIII foi de 64,02±28,80. Diferenças significativas (P 0,001) foram evidentes entre GI e GIII e GII e GIII, mas nمo entre os Grupos I e II. Os resultados revelaram diminuiçمo da densidade celular e da hexagonalidade com o avanço da idade. O endotélio da cَrnea de coelhos sofre alteraçُes devido ao avanço da idade tanto na densidade celular e quanto na morfologia.

The aim was to investigate the ultrastructural changes in the corneal endothelium of pigs induced by intracameral 0.05% brilliant blue. Twenty swine corneas were separated into two groups, the right eye bulbs (control group) and the left eye bulbs (experimental group) of the same animal. All the eye bulbs were evaluated with specular microscopy. The cornea of the right eye bulbs was excised and in the left eye bulbs 0.2ml of 0.05% brilliant blue vital dye (OPTH-blue±) was injected into the anterior chamber, where it remained for one minute. Then the anterior chamber was cleaned with a balanced salt solution injection and the cornea was excised too. All the corneas were evaluated by scanning electron microscopy to evaluate the changes on the endothelium caused by the brilliant blue dye. There were no significant differences between the right corneal endothelium cells and the left corneal endothelium cells with scanning electron microscopy after intracameral use of 0.05% brilliant blue dye. The 0.05% brilliant blue dye concentration did not cause deleterious effects for the swine corneal endothelium after intracameral use and can be a choice for safe staining of the anterior capsule of the lens in cataract surgery.(AU)

Inicialmente todos os bulbos oculares foram avaliados por microscopia especular. As córneas dos bulbos oculares do grupo controle foram excisadas, enquanto nos bulbos oculares do grupo experimental foram injetados 0,2ml do corante vital azul brilhante 0,05% na câmara anterior e mantido por um minuto. Após esse período a câmara anterior foi lavada com solução salina balanceada e as córneas foram excisadas. Todas as córneas excisadas foram avaliadas por microscopia eletrônica de varredura para verificar a ocorrência possíveis alterações no endotélio corneano causadas pelo corante. Não foram observadas diferenças ultraestruturais durante a avaliação endotelial por microscopia eletrônica de varredura das córneas do grupo controle e experimental após a aplicação do azul brilhante 0,05% na câmara anterior. O corante azul brilhante na concentração 0,05% não causou danos endoteliais após seu uso intracameral em suínos e pode ser uma alternativa segura para a coloração da cápsula anterior da lente na cirurgia de catarata.(AU)

This study evaluated the cervical and transdiaphragmatic thoracoscopic approaches regarding their implementation, intrathoracic evaluation and application of a chest tube, using the treatment of pneumothorax as an experimental model. After injection of 20ml kg-1 of air per hemithorax, thoracoscopy was made by transdiaphragmatic paraxiphoid or cervical positions. After cavity examination, a thoracic drain was inserted using the surgical site to drain the pneumothorax. The cardiorespiratory function and arterial blood gas were measured during time of evaluation. The cavity examination allowed visualizing the aspect and function of intrathoracic structures. There were no significant differences between the two approaches when comparing the measurements made in each period evaluated. Both enabled intracavitary exploration and application of thoracic drain. Cervical access shows viability, but resulted in the death of two patients, and it not recommended as a substitute for the latter in the insertion of thoracic drains in dogs.(AU)
Este estudo avaliou os acessos toracoscópicos cervical e paraxifóide em relação à sua aplicação, avaliação intratorácica e colocação de dreno torácico, utilizando o tratamento de pneumotórax como modelo experimental. Após a injeção de 20ml kg-1 de ar por hemitórax, a toracoscopia foi realizada pelas técnicas cervical ou paraxifóide transdiafragmática. Após a exploração da cavidade, foi inserido um dreno torácico utilizando o acesso cirúrgico para drenar o pneumotórax. A função cardiorrespiratória e a gasometria arterial foram aferidas durante o tempo de avaliação. A exploração da cavidade permitiu visualização do aspecto e função das estruturas intratorácicas. Não houve diferenças significativas entre os dois acessos quanto aos dados aferidos em cada período de avaliação. Ambos permitiram exploração intracavitária e aplicação do dreno torácico. O acesso cervical demonstra viabilidade, porém resultou na morte de dois pacientes, e não é recomendado como substituta à paraxifóide transdiafragmática para a aplicação de drenos torácicos em cães.(AU)

Cases: 1- An eleven-month-old bitch was admitted at the HV-UPF nine days after OVH performed elsewhere, with omentum evisceration due to suture dehiscence. During emergency surgery both ovaries were found surrounded by nylon tie-raps and fi brous tissue adherence. Peritonitis signs were recognizable. Bilateral ovariectomy with nylon 2-0 was performed and the remaining uterus was removed. 2- A five-years-old bitch was referred to the HV-UPF ten days after OVH performed elsewhere, with apathy and suture dehiscence. Free liquid was identified around the bladder and kidneys using the ultrasound exam. Intense hemorrhage from uterine vessels was found during celiotomy. A nylon tie-rap was found loose on the abdominal cavity and another couple were found at both ovaries surrounded by fibrous tissue adherence. Bilateral ovariectomy with nylon 2-0 was performed and a blood transfusion was necessary. 3- A three-years-old bitch was admitted at the HCV-UFRGS six days after OVH performed at another institution, presenting suture dehiscence and evisceration. During emergency surgery, bladder, intestine and musculature necrosis due to the contact with sharp edged nylon tie-raps (prior placed as hemostatic devices), intense fibrous tissue adherence and peritonitis were identified. 4- A two-years-old bitch was referred to the HCV-UFRGS one year after OVH performed elsewhere, with a four-month p
Background: Routine neutering of bitches is typically carried out by ovariohysterectomy (OVH) in Veterinary Medicine, seen by many as a simple procedure.

It has been described the use of non-surgical polyamide tie-raps as a hemostatic closure method by some authors but there are few papers describing the consequenses of such use. The aim of this study is to report four cases of surgical complications associated with nylon tie-raps use on OVHs on bitches referred to the Veterinary Teaching Hospitals of the Federal University of Rio Grande do Sul (HCV-UFRGS) and Passo Fundo University (HV-UPF), both at the State of Rio Grande do Sul.Cases: 1- An eleven-month-old bitch was admitted at the HV-UPF nine days after OVH performed elsewhere, with omentum evisceration due to suture dehiscence.

Abdominal communication was suspected and therefore the patient was submitted to exploratory celiotomy. During surgery intense fibrous tissue adherence were found on both mesovarium. Stump granuloma and a sinus tract were also identified in the right side. Sharped nylon tie-raps were found among the fibrous tissue and were then replaced by non-absorbable suture. Discussion: OVH complications such as suture dehiscence, evisceration, peritonitis and loosen tie-raps, all seen on cases 1, 2 and 3 are usual when there is trans-operatory contamination and can probably be associated with technique failure, as described by other authors. Self-trauma must be avoided throughout the use of Elizabethan collar, but this recommendation was not followed by the patients' owners on any of the cases even though it had been prescribed by the veterinarian. Fibrous tissue and granulomas were found on all cases due to the tie-raps, what brings the question about its real effects to the animal organism. All the patients had satisfiable recovery after the emergency surgeries. There is urgent need of scientific investigations about the grave consequences of the inadequate use of poliamide tie-raps before assigning it as a hemostatic material.

Introdução: Proptose ocular signifi ca o deslocamento do globo ocular cranial às pálpebras e frequentemente encarcerado por elas. As causas para essa condição são diversas, como: trauma contuso na região da cabeça, acidentes automobilísticos, mordeduras e quedas. A espécie mais acometida por essa emergência oftálmica é a canina. O tratamento envolve o reposicionamento do globo ocular e a tarsorrafi a temporária. A enucleação pode ser necessária caso o dano ocular seja severo. Objetivou-se, valendo-se de estudo retrospectivo, avaliar o perfi l racial, a faixa etária e o sexo dos cães com proptose ocular atendidos no Hospital de Clínicas Veterinárias da Universidade Federal do Rio Grande do Sul.Materiais, Métodos e Resultados: Para a realização do presente estudo foram pesquisadas as fi chas de atendimento referentes à proptose ocular atendidas no Hospital de Clínicas Veterinárias da Universidade Federal do Rio Grande do Sul. No período de março de 2005 até abril de 2012, foram atendidos 79 cães acometidos por proptose ocular. Assim, classifi caram- -se os pacientes conforme a raça, a faixa etária e o sexo. A partir dos dados coletados, observou-se em relação à raça que os caninos sem raça defi nida (58,2%), Pinscher (10,1%), Poodle (8,8%), Pug (3,8%) e Shih Tzu (3,8%) foram os mais acometidos pela proptose ocular.

Introdução: O glaucoma é uma doença grave associada a diversos fatores como o aumento da pressão interna do bulbo do olho, a perda das células ganglionares da retina, perda de axônios do nervo óptico e escavação da cabeça do nervo óptico. Trata-se de uma emergência oftálmica, sendo uma das principais causas de cegueira nos cães. Objetivou-se conhecer quais as raças mais frequentemente acometidas pelo glaucoma, a fi m de auxiliar no direcionamento do diagnóstico.Materiais, Métodos e Resultados: Foi realizado o levantamento das fi chas de atendimento oftálmico dos casos de cães com glaucoma no período de setembro de 2007 a abril de 2012 junto ao Hospital de Clínicas Veterinárias da Universidade Federal do Rio Grande do Sul. Durante o estudo os animais foram separados por raça para que se obtivesse o percentual das raças com maior incidência. No período mencionado foram atendidos 83 casos de cães com glaucoma, sendo que as raças mais frequentemente acometidas foram os cães sem raça defi nida (28,92%), Poodle (24,1%), Pinscher (9,96%), Basset Hound (6,02%) e Cocker (4,81%).Discussão: O glaucoma é frequentemente diagnosticado em cães, sendo geralmente ocasionado pela obstrução ou diminuição da drenagem do humor aquoso. A manutenção da pressão intraocular dentro dos padrões normais depende do equilíbrio entre a taxa de produção e de fi ltração do humor aquoso. Admite-se o aumento da

In this study the authors compared two different procedures of ovariosalpingohysterectomy (OSH) in dogs. For that, 18 dogs were randomly assigned into 2 different groups: group I (GI) in which the OSH was performed by celiotomy and group II (GII) in which it was a video-assisted procedure using two portals positioned in the umbilical and pre pubic regions, under dorsal recumbence position. In both groups the method of hemostasis was the Ligasure atlas®. The authors did not observe significant differences between both methods for the surgical time or complications during and after the surgical procedure and blood loss. It was concluded that OSH using video-assisted surgery with two portals and the conventional technique, both using Ligasure atlas® are safe, fast and effective to be used in dogs.

O presente estudo objetivou desenvolver um protocolo de anestesia intravenosa total para a realização de ovariosalpingohisterectomia laparoscópica em cadelas. Foram utilizadas oito fêmeas submetidas a ovariosalpingohisterectomia videolaparoscópica de forma padronizada. A medicação pré-anestésica a foi realizada com acepromazina e a indução com propofol. Na manutenção utilizou-se propofol por infusão contínua associado à anestesia epidural com lidocaína. Como parâmetros avaliaram-se a FC, FR, temperatura retal, TPC, SpO2, PAM, PVC e gasometria arterial. Todos animais apresentaram diminuição da FC, FR, temperatura corporal, hipotensão e acidose respiratória não compensada durante o período anestésico. Dois animais apresentaram complicações anestésicas que culminaram com o óbito. Com os resultados obtidos, não recomenda-se o emprego desta metodologia para cirurgias laparoscópicas sem a utilização de ventilação controlada(AU)
The aim of study was the development of a total intravenous anesthesia protocol for the pattern laparoscopic ovariohysterectomy in eight bitches. Acepromazine and propofol was use on premedication and induction respectively. In the maintenance continuous infusion of propofol associated to epidural lidocaine 2% was employed. Parameters as heart rate (HR), respiratory rate (RR), rectal temperature, capillary perfusion time (CPT), SpO2, mean arterial pressure (MAP), mean venous pressure (MVP) and arterial gasometry was evaluated it. All animals had reduction of the HR, RR, temperature, hypotension and acidosis not compensated during the anesthesia. Two animals had complications and death. The protocol employed in this study is not recommended without the use of controlled ventilation(AU)

O presente estudo objetivou desenvolver um protocolo de anestesia intravenosa total para a realização de ovariosalpingohisterectomia laparoscópica em cadelas. Foram utilizadas oito fêmeas submetidas a ovariosalpingohisterectomia videolaparoscópica de forma padronizada. A medicação pré-anestésica a foi realizada com acepromazina e a indução com propofol. Na manutenção utilizou-se propofol por infusão contínua associado à anestesia epidural com lidocaína. Como parâmetros avaliaram-se a FC, FR, temperatura retal, TPC, SpO2, PAM, PVC e gasometria arterial. Todos animais apresentaram diminuição da FC, FR, temperatura corporal, hipotensão e acidose respiratória não compensada durante o período anestésico. Dois animais apresentaram complicações anestésicas que culminaram com o óbito.

Introdução: O glaucoma é uma doença grave associada a diversos fatores como o aumento da pressão interna do bulbo do olho, a perda das células ganglionares da retina, perda de axônios do nervo óptico e escavação da cabeça do nervo óptico. Trata-se de uma emergência oftálmica, sendo uma das principais causas de cegueira nos cães. Objetivou-se conhecer quais as raças mais frequentemente acometidas pelo glaucoma, a fi m de auxiliar no direcionamento do diagnóstico.Materiais, Métodos e Resultados: Foi realizado o levantamento das fi chas de atendimento oftálmico dos casos de cães com glaucoma no período de setembro de 2007 a abril de 2012 junto ao Hospital de Clínicas Veterinárias da Universidade Federal do Rio Grande do Sul. Durante o estudo os animais foram separados por raça para que se obtivesse o percentual das raças com maior incidência. No período mencionado foram atendidos 83 casos de cães com glaucoma, sendo que as raças mais frequentemente acometidas foram os cães sem raça defi nida (28,92%), Poodle (24,1%), Pinscher (9,96%), Basset Hound (6,02%) e Cocker (4,81%).Discussão: O glaucoma é frequentemente diagnosticado em cães, sendo geralmente ocasionado pela obstrução ou diminuição da drenagem do humor aquoso. A manutenção da pressão intraocular dentro dos padrões normais depende do equilíbrio entre a taxa de produção e de fi ltração do humor aquoso. Admite-se o aumento da

Cases: 1- An eleven-month-old bitch was admitted at the HV-UPF nine days after OVH performed elsewhere, with omentum evisceration due to suture dehiscence. During emergency surgery both ovaries were found surrounded by nylon tie-raps and fi brous tissue adherence. Peritonitis signs were recognizable. Bilateral ovariectomy with nylon 2-0 was performed and the remaining uterus was removed. 2- A five-years-old bitch was referred to the HV-UPF ten days after OVH performed elsewhere, with apathy and suture dehiscence. Free liquid was identified around the bladder and kidneys using the ultrasound exam. Intense hemorrhage from uterine vessels was found during celiotomy. A nylon tie-rap was found loose on the abdominal cavity and another couple were found at both ovaries surrounded by fibrous tissue adherence. Bilateral ovariectomy with nylon 2-0 was performed and a blood transfusion was necessary. 3- A three-years-old bitch was admitted at the HCV-UFRGS six days after OVH performed at another institution, presenting suture dehiscence and evisceration. During emergency surgery, bladder, intestine and musculature necrosis due to the contact with sharp edged nylon tie-raps (prior placed as hemostatic devices), intense fibrous tissue adherence and peritonitis were identified. 4- A two-years-old bitch was referred to the HCV-UFRGS one year after OVH performed elsewhere, with a four-month p
Background: Routine neutering of bitches is typically carried out by ovariohysterectomy (OVH) in Veterinary Medicine, seen by many as a simple procedure. During the conventional approach the points of attachment of the uterus and ovaries are double ligated with absorbable or non-absorbable sutures or even with titanium clamps. It has been described the use of non-surgical polyamide tie-raps as a hemostatic closure method by some authors but there are few papers describing the consequenses of such use. The aim of this study is to report four cases of surgical complications associated with nylon tie-raps use on OVHs on bitches referred to the Veterinary Teaching Hospitals of the Federal University of Rio Grande do Sul (HCV-UFRGS) and Passo Fundo University (HV-UPF), both at the State of Rio Grande do Sul.Cases: 1- An eleven-month-old bitch was admitted at the HV-UPF nine days after OVH performed elsewhere, with omentum evisceration due to suture dehiscence.

Introdução: Proptose ocular signifi ca o deslocamento do globo ocular cranial às pálpebras e frequentemente encarcerado por elas. As causas para essa condição são diversas, como: trauma contuso na região da cabeça, acidentes automobilísticos, mordeduras e quedas. A espécie mais acometida por essa emergência oftálmica é a canina. O tratamento envolve o reposicionamento do globo ocular e a tarsorrafi a temporária. A enucleação pode ser necessária caso o dano ocular seja severo. Objetivou-se, valendo-se de estudo retrospectivo, avaliar o perfi l racial, a faixa etária e o sexo dos cães com proptose ocular atendidos no Hospital de Clínicas Veterinárias da Universidade Federal do Rio Grande do Sul.Materiais, Métodos e Resultados: Para a realização do presente estudo foram pesquisadas as fi chas de atendimento referentes à proptose ocular atendidas no Hospital de Clínicas Veterinárias da Universidade Federal do Rio Grande do Sul. No período de março de 2005 até abril de 2012, foram atendidos 79 cães acometidos por proptose ocular. Assim, classifi caram- -se os pacientes conforme a raça, a faixa etária e o sexo. A partir dos dados coletados, observou-se em relação à raça que os caninos sem raça defi nida (58,2%), Pinscher (10,1%), Poodle (8,8%), Pug (3,8%) e Shih Tzu (3,8%) foram os mais acometidos pela proptose ocular. Em relação às faixas etárias, verifi cou-se 35,5% dos pacientes c
