Diarrhea in cats infected with Cystoisospora spp. - evaluation of the neutrophil-to-lymphocyte ratio and monocyte-to-lymphocyte ratio

Background: Cystoisospora spp. is considered a potential pathogen to cause diarrhoea in cats, and the disease occurs clinically, especially in young, weak and immunocompromised cats. The present study aimed to evaluate the clinical utility and diagnostic roles of neutrophil-to-lymphocyte ratio (NLR) and monocyte-to-lymphocyte (MLR) ratios in diarrheal cats infected with Cystoisospora spp. Materials, Methods & Results: Twenty-five cats with diarrhea due to infection caused by Cystoisospora spp. and 15 healthy cats were included in this study. The anamnesis, clinical and laboratory findings of all cats were recorded. A clinical severity score was generated for diarrheal cats, which included activity, appetite, presence of vomit, and faecal consistency. Also, cats infected with Cystoisospora spp. were classified as systemic inflammatory response syndrome (SIRS) positive (+) and SIRS (-) group according to the presence of at least 3 of the SIRS criteria. The Cystoisospora spp. oocysts were diagnosed by direct smear and simple faecal flotation. Cats found positive for other parasitic and protozoal agents by faeces examination were excluded from the study. Complete blood counts (CBC) were performed with an automated blood cell counter for all cats. Blood smears were prepared (with May-Grunwald Giemsa) from samples, and the CBC results were confirmed microscopically (obj.100x). White blood cell (WBC), neutrophil, lymphocyte and monocyte counts were recorded directly from the CBC. The neutrophil-to-lymphocyte ratio was calculated as the ratio of the absolute neutrophil count to the absolute lymphocyte count. The monocyte-to-lymphocyte was calculated as the absolute monocyte count ratio to the absolute lymphocyte count. White blood cell (P = 0.015), neutrophil (P = 0.001), monocyte (P = 0.033), NLR (P = 0.000) and MLR (P = 0.042) of diarrheal cats infected with Cystoisospora spp. were significantly higher than in the healthy group. There was no significant difference between groups in the lymphocyte counts (P > 0.05). SIRS (+) group had statistically significantly higher WBC (P = 0.014), neutrophil counts (P = 0.000), NLR (P = 0.000) and MLR (P = 0.037) than the healthy group. Also, neutrophil counts and NLR of the SIRS (+) group were statistically significantly higher than the SIRS (-) group (P = 0.032; P = 0.001, respectively). However, there was no significant difference SIRS (+), SIRS (-), and healthy groups regarding lymphocyte and monocyte counts (P > 0.05). The clinical severity of the disease positively correlated with NLR and MLR. Also, the best cut-off value of NLR to predict SIRS was > 1.67, with 92.86% sensitivity and 84.62% specificity. MLR was not a useful predictor for SIRS. Discussion: NLR and MLR are parameters derived from complete blood count. In recent years, they have been used in human and veterinary medicine as a biomarker in the diagnosis, prognosis and treatment follow-up of various diseases and provide valuable information about inflammation. In cats, there are limited studies on NLR, and to our knowledge, there are no studies on MLR. The current study suggests that NLR and MLR may be used to determine the severity of the inflammatory condition in diarrheal cats infected with Cystoisospora spp., and NLR is a useful marker for predicting SIRS status in these cats. In addition, this study also will contribute to larger-scale studies in the future.

Analgesia perioperatória de gatas submetidas a ovariohisterectomia eletiva - uso preemptivo de carprofeno ou grapiprant / Perioperative analgesia in cats undergoing elective ovariohysterectomy - preemptive use of carprofen or grapiprant

Background: The nonsteroidal anti-inflammatory drugs (NSAIDs) exert their analgesic effect through peripheral inhibition of prostaglandin synthesis and a variety of other peripheral and central mechanisms. However, NSAIDs are associated with some adverse effects, mainly related to the gastrointestinal, renal, and hepatic systems, highlighting the need for research to develop safer drugs. Therefore, the aim of this study was to evaluate the efficacy of preoperative oral administration of carprofen or grapiprant in female cats submitted to elective ovariohysterectomy on the quality of perioperative analgesia and the need for hypnotic and analgesic drugs. Materials, Methods & Results: Thirty-three adult female cats were selected, without defined breed and healthy based on physical examination, routine laboratory analyses (complete blood count, total protein, Heinz body investigation and serum quantification of alanine transaminase [ALT], aspartate transaminase [AST], gamma glutamyl transpeptidase [GGT], alkaline phosphatase [ALP], urea, frutosamine, and glucose) and negative tests for feline immunodeficiency virus (FIV) and feline leukemia virus (FeLV). After 3 days of adaptation, they were submitted to ovariohysterectomy by celiotomy and randomly allocated into 2 groups according to the preoperative drug used: GCAR [carprofen - 4 mg/kg, VO, 2 h before surgery; n = 11] and GGRA (grapiprant - 2 mg/kg IV, 2 h before surgery; n = 21]. The cats were pre-medicated with acepromazine 0.05 mg/ kg IV and later submitted to general anesthesia with propofol intravenously. Anesthesia was maintained with isoflurane in 100% oxygen. After anesthetic induction, a continuous infusion of remifentanil at a rate of 10 µg/kg/h was initiated. During the transanesthetic period, the parameters of heart rate; respiratory rate; systolic, mean, and diastolic arterial pressure using the oscillometric method; electrocardiogram; rectal temperature; partial pressure of CO2 at the end of expiration: and partial saturation of O2 in hemoglobin were continuously monitored. The evaluation of nociception was based on the changes in the aforementioned physiological parameters. The rate of remifentanil used did not change over time with the use of carprofen. However, animals that received grapiprant required a lower remifentanil dose at 20, 25, and 30 min during the procedure. The female cats that received carprofen showed an increase in mean heart rate at 30 min compared to that at 20 and 25 min. In the Grapiprant group, the heart rate at 35 min was higher only than that observed at 25 min. Discussion: The remifentanil rate did not differ between the groups, even between the times for GCAR. However, the remifentanil rate was lower from 20 min of the procedure for GGRA. This decrease may be related to a decrease in the need for anesthetics and analgesics by decreasing temperature, which causes decreases in metabolism and surgical stimulation. The increase in systolic, mean, diastolic, and heart rate arterial pressure parameters observed in both treatments after 15 min of anesthesia is related to the nociceptive stimulus resulting from traction and ligation of the ovarian pedicles and maneuvers for exteriorization of the uterus. These are considered the moments of greater surgical stimulus during ovariohysterectomy, evidenced by the greater release of cortisol and increase in physiological parameters. The results of this study show that the administration of carprofen or grapiprant was clinically similar when used preemptively for perioperative analgesia in cats submitted to elective ovariohysterectomy.

Pyometra in queens - changes in haemato-biochemical parameters

Background: Pyometra is a bacterial and hormone-induced reproductive disease that occurs in the post-estrus luteal phase in intact queens. Pyometra is more common in the diestrus period due to the high progesterone concentration (in queens that mated, spontaneously ovulated, or were induced to ovulate). However, it can also be seen due to the use of exogenous hormones such as progesterone for the suppression of estrus. More research is needed in cases of pyometra in queens, as well as in bitches. Because, considering that the pathogenesis and characteristics of feline pyometra is similar to bitches, studies on pyometra-affected bitches are taken as reference in studies and applications on queens. From this point of view, the aims of this study were to reveal the changes in complete blood count, blood gas, and serum biochemistry parameters in feline pyometra cases and to determine the correlation between the mentioned parameters. Materials, Methods & Results: In the study, a total of 25 female cats of different breeds were used, between the ages of 6 months and 7 years, 15 were diagnosed with pyometra, and 10 healthy. Anamnesis, clinical findings, and ultrasonographic examinations were used in the diagnosis of pyometra. Abdominal ultrasonography was performed on queens brought to the clinic with complaints such as anorexia, polydipsia, polyuria, abdominal tension, and fever. The control group (n =10) consisted of queens that were introduced to the clinic and were reproductively healthy. Before any treatment in queens with pyometra and the control group, 1 mL blood samples were taken from v. cephalica to evaluate complete blood count, blood gases and serum biochemistry parameters. In complete WBC, Lym, Mon, Gra, RBC, Hb, HCT, MCV, MCH and PLT parameters and, blood gas parameters such as pH, pCO2 , pO2 , sO2 , Na, K, Cl, lactate, glucose, HCO3 , and BE were also evaluated in taken blood samples. Biochemical parameters BUN, creatinine, ALT, AST, ALP, amylase, T.BIL, D.BIL, P, CHOL, TG, LDH, TP, CPK, ALP, Ca, GGT were measured in serum samples. After examination and laboratory analysis, ovariohysterectomy was performed on queens as a treatment. Granulocyte, WBC, HCT and MCH levels of the pyometra group were higher (P < 0.05) and Lym levels were lower (P < 0.05) compared to the control group. According to these results, pH, HCO3 , and BE were lower (P < 0.05) in queens with pyometra than those in the control group, while Na and lactate parameters were higher (P < 0.05). According to the results of biochemical analysis, it was determined that BUN, creatinine levels, GGT, and LDH enzyme activities were found to be higher in the pyometra group compared to the control group, while the Ca level was found to be low (P < 0.05). A positive correlation was observed between BUN and creatinine and LDH, WBC, granulocyte, HCT, and lactate, and a negative correlation between lymphocytes, pH, and BE in the correlation analysis performed on queens with pyometra and control group. However, a positive correlation was observed between creatinine and LDH and HCT, and a negative correlation between lymphocyte, pH and BE. Discussion: There is not enough information about pyometra in queens. As a result, it was determined that there were significant changes in complete blood count, blood gases and serum biochemical parameters in queens with pyometra in this study. These changes were generally thought to be related to dehydration and sepsis or endotoxemia. In addition, it was evaluated that prerenal azotemia occurring in pyometra affected queens may cause renal dysfunction. For this reason, it is thought that the results obtained in the presented study may contribute to the diagnosis, treatment, and prognosis of pyometra cases in queens.

Tratamento de tromboembolismo e preparo para implantação de prótese osteointegrada com oxigenioterapia hiperbárica em uma gata / Treatment of tromboembolism and preparation for an osseointegrated prothesis fixation with hyperbaric oxygen therapy in a kitten

Background: Ischemic neuromyopathy is the most common reason for amputation in cats. In veterinary medicine, the use of prosthetic limbs is not widespread; therefore, in most cases total limb amputation is indicated. However, hyperbaric oxygen therapy (HBOT) is an alternative with several benefits for the treatment of vascular disorders with reperfusion, ischemia, and infection. Therefore, this study aimed to report the positive effects of HBOT on the treatment of ischemic neuromyopathy secondary to arterial thromboembolism on the patient's clinical improvement, and on the preparation of the patient for insertion of an osseointegrated prosthesis. Case: A 6-month-old mixed-breed kitten returned for treatment after undergoing surgery seven days earlier for reduction of traumatic diaphragmatic hernia, during which it suffered a cardiorespiratory arrest. The patient presented with acute pelvic limb paralysis with 24-h evolution, absent femoral pulse, plantar cushions and dorsal part of the limbs cold and pale. After supportive therapy and diagnosis of aortic thromboembolism by arterial Doppler, the patient started adjunctive treatment with HBOT from the first day of hospitalization. Sessions took place in an exclusive hyperbaric chamber for animals and lasted 60 min at a pressure of 2.5 absolute atmospheres and 100% oxygen, initially every 12 h. However, during the first 5 days of hospitalization, the distal region of both pelvic limbs began to show tissue devitalization and edema, and hematologic parameters showed changes on the 7th day. The right pelvic limb (RPL) showed more involvement of superficial tissues, extending to the tarsometatarsal joint region. After 8 days of hospitalization, the devitalized tissue was debrided. The RPL had an extensive devitalized area with exposed bone in the phalanges and necrosis in the pads. The left pelvic limb (LPL) suffered minor complications, with involvement of the phalangeal region. After 12 days, with HBOT every 48 h, exuberant granulation tissue was observed. After 17 days, the patient was discharged, and HBOT sessions were performed weekly. Gangrene of the midfoot and lack of proprioception were observed in RPL, while LPL showed bone divulsion of the 1st, 3rd, and 4th phalanges. Because of the poor prognosis for limb viability, the RPL was partially amputated, and a self-threaded intraosseous prosthesis was inserted. Discussion: The cardiorespiratory arrest that occurred during the surgical procedure to reduce the diaphragmatic hernia without thromboprophylaxis may have contributed to the peripheral ischemia. HBOT was proposed for the adjuvant treatment of ischemic injury because it is especially indicated for cases of ischemia-reperfusion injury. The main hematological parameters were evaluated at an average interval of 7 days. While the platelet count and hematocrit increased, the leukocytosis decreased. This demonstrates the benefit of oxygen therapy in the reported patient. The use of HBOT in orthopedic injuries is known to result mainly in stimulation of osteoblasts, promoting osseointegration of the prosthesis. We conclude that the adjuvant treatment with HBOT helped to preserve a large segment of both pelvic limbs, prevent the progression of necrosis, and provide a healthy bed for fixation of an osseointegrated prosthesis in the RPL, resulting in clinical improvement of the patient.

Hipertensão situacional em cães dóceis adultos / Situational hypertension in docile adult dogs

A hipertensão arterial sistêmica (HAS) é uma enfermidade silenciosa que pode afetar gatos e cães. Embora bastante descrita em felinos, a "Síndrome do Jaleco Branco", ou hipertensão situacional, é pouco relatada em cães. Assim, este trabalho tem como objetivo mostrar a importância do estresse na aferição da pressão arterial de cães adultos. O estudo foi realizado com 46 cães de ambos os sexos, dóceis, adultos, e aparentemente saudáveis. Após anamnese, exame físico, ambientação e manejo amigável dos animais, mensurou-se a pressão arterial sistólica (PAS) pelo método Doppler no membro torácico. Foram feitas várias aferições para obtenção de média aritmética. Animais com até 160mmHg de PAS, na primeira aferição, foram considerados normotensos (36 cães, correspondente a 78,26%). Para os que tiveram PAS maior ou igual a 160mmHg (dez cães, equivalente a 21,74%), realizou-se um segundo momento de aferição, após 15 a 30 minutos, com os animais em repouso. Assim, seis desses cães apresentaram PAS entre 154mmHg e 200mmHg, sendo, então, um considerado pré-hipertenso e cinco hipertensos, e outros quatro considerados normotensos. Para o animal com pré-hipertensão e para os hipertensos, realizaram-se exames complementares, pelos quais quatro cães foram diagnosticados com doença renal crônica e dois com dislipidemia familiar dos Schnauzers. Dessa forma, pode-se concluir que, dos 46 cães avaliados, 36 apresentaram-se normotensos (78,26%), um pré-hipertenso (2,17%), cinco hipertensos (10,87%) e quatro com hipertensão situacional (8,7%). Portanto, para cães em ambiente hospitalar, é importante realizar um manejo amigável e, quando necessário, mais de um momento de aferição de PAS para evitar diagnósticos errôneos de HAS.

Systemic arterial hypertension (SAH) is a silent disease that can affect cats and dogs. Although well described in felines, "white coat syndrome", or situational hypertension, is little reported in dogs. Thus, this paper aims to show the importance of stress in the measurement of blood pressure from adult dogs. The study was conducted with 46 dogs of both sexes, docile, adults, apparently healthy. After anamnesis, physical examination, ambiance, and friendly management of animals, systolic blood pressure (SBP) was measured by the doppler method in the thoracic limb. Several measurements were made to obtain an arithmetic average. Animals up to 160mmHg of SBP, in the first measurement, were considered normotensive (36 dogs, corresponding to 78.26%). For those with SBP higher than or equal to 160mmHg (10 dogs, equivalent to 21.74%), a second measurement was performed after 15 to 30 minutes, with the animals at rest. Therefore, six of these dogs presented SBP between 154mmHg and 200mmHg (one considered prehypertense and five hypertensives) and four normotensives. For the animal with prehypertension and the hypertensives, complementary examinations were performed, in which four dogs were diagnosed with chronic kidney disease and two with family dyslipidemia of the Schnauzers. Thus, it can be concluded that among the 46 dogs evaluated, there were 36 normotenses (78.26%), a one prehypertense (2.17%), five hypertensives (10.87%), and four with situational hypertension (8.7%). Therefore, regarding dogs in a hospital environment, it is important to perform friendly management and, when necessary, more than one moment of SBP measurement to avoid erroneous diagnoses of SAH.

Nutraceticals for dissolving nephrolites in cats

Background: Nephrolithiasis is a condition frequently observed in felines, with or without concomitant chronic kidneydisease, constituting the major cause of ureteral obstruction and causing progressive damage to the renal parenchyma. About90% of nephrolites are composed of calcium oxalate, which cannot dissolve, and its incidence has increased substantiallyin recent years, along with its recurrence. There are functional foods known as nutraceuticals provides health benefits suchas renoprotection. Due to these benefits and the high prevalence of nephrolithiasis in feline species, the present study aimedto evaluate the efficacy of the association of some nutraceuticals in the dissolution of nephrolites.Materials, Methods & Results: The included cats had an ultrasound diagnosis of nephrolithiasis that, on clinical examination, showed: (i) the absence of previous or concomitant treatment for urinary infections and/or vesical and renal lithiasis;(ii) absence of genitourinary clinical manifestations; (iii) absence of obstructive processes; and (iv) absence of concomitantureterolithiasis. We separated 51 cats with nephrolithiasis into 2 groups: control (n = 12) and study (n = 39). The controlgroup received a placebo and the study group, nutraceuticals (magnesium chelate, resveratrol, vitamin K2, docosahexaenoicacid, and eicosapentaenoic acid). Laboratory tests (blood and urine) and abdominal imaging (ultrasound) were performedat day 0 and 30 days after enrollment. Monitoring the therapeutic efficacy in both groups was performed on day 30 for theCG and on days 30, 60, and 90 for the EG. The CG cats, after this step, were referred to surgery or to the EG, with priorauthorization from their tutors. The diameter of nephrolites was significantly different before and after treatment, indicating a reduction in nephroliths over time. During the use of the nutraceutical formulation by the EG and use of placebo...

Human rabies post-exposure prophylaxis: a review of the treatment of accidents involving domestic cats / Profilaxia pós-exposição da raiva humana: uma revisão dos tratamentos envolvendo gatos domésticos

Rabies is an anthropozoonosis that presents approximately 100% lethality and expensive preventive assistance. Many human post-exposure anti-rabies treatments indicated for people at risk of exposure to rabies virus, usually due to some aggression by a mammalian animal, are instituted annually. This study aimed to evaluate the initial care of post-exposure prophylaxis of human rabies in Belo Horizonte between 2007 and 2016, involving accidents with domestic cats. It was found 71.1% agreement between the treatments instituted by health services and the protocol of the Ministry of Health. Treatments classified as insufficient totaled 18.3% and excessive, 10.6%. The animals were healthy in 68% and observable in 68.4% of the cases. Treatments involving the use of anti-rabies vaccine totaled 87.7%. The most frequent treatment adopted by the health services was observing the animals associated with the human anti-rabies vaccination in 56.7% of the cases. Imperfections in the filling of the notifications must be revised to enable improvements for future analyses. As for human prophylactic anti-rabies care, forming a multidisciplinary health team including veterinarians would be well on the way to improving the service offered.(AU)

A raiva é uma antropozoonose que apresenta aproximadamente 100% de letalidade e alto custo na assistência pre-ventiva. É instituído anualmente, um elevado número de tratamento antirrábico humano pós-exposição, o qual é indicado para pessoas que se encontram sob risco de exposição ao vírus rábico, geralmente devido a alguma agressão por animal mamí-fero. Este trabalho teve como objetivo avaliar o atendimento inicial da profilaxia pós-exposição da raiva humana, em Belo Horizonte, entre os anos de 2007 a 2016, envolvendo acidentes com gatos domésticos. Encontrou-se 71,1% de concordân-cia entre os tratamentos instituídos pelos serviços de saúde e o protocolo do Ministério da Saúde. Tratamentos classificados como insuficientes totalizaram 18,3% e excessivos 10,6%. Os animais eram sadios em 68% e observáveis em 68,4% dos casos. Tratamentos que envolviam o uso de vacina antirrábica totalizaram 87,7%. O tratamento adotado pelos serviços de saúde com maior frequência foi a observação do animal associada à vacinação antirrábica humana em 56,7% dos casos. É necessário que imperfeições no preenchimento das notificações sejam revistas de forma a possibilitar melhorias para análises futuras. Quanto ao atendimento antirrábico profilático humano, a formação de uma equipe multidisciplinar de saúde com inclusão de médi-cos veterinários seria uma forma de aprimorar o serviço oferecido.(AU)

Avaliação histopatológica das principais lesões testiculares em gatos adultos submetidos à orquiectomia eletiva / Histopathological evaluation of the main testicular lesions in adult cats submitted to elective orchiectomy

O estudo das lesões testiculares em felinos é essencial no diagnóstico das doenças reprodutivas, uma vez que as gônadas podem apresentar alterações importantes, mesmo quando macroscopicamente normais. Assim, este trabalho foi desenvolvido com o objetivo de avaliar as principais lesões testiculares em gatos adultos submetidos à orquiectomia eletiva, determinando as lesões de maior frequência. Para isso, foram utilizados 25 gatos machos, adultos, com idade entre um e dois anos. Todos os animais eram provenientes do Programa de Controle Populacional de Animais de Estimação Pelo Método de Esterilização Cirúrgica, do Hospital Veterinário da Universidade Federal de Uberlândia (HOVET-UFU). Após a orquiectomia, os testículos foram coletados e enviados ao Setor de Patologia Animal do HOVET-UFU, onde foram separados dos seus respectivos epidídimos. Foram obtidas as dimensões de comprimento, altura, largura, peso e volume de cada testículo. Esses foram então fixados em formalina 10%, por 24 horas, e clivados nas regiões cranial, média e caudal. Os fragmentos foram submetidos ao processamento para inclusão em parafina e coloração em hematoxilina e eosina. Mesmo sem alterações macroscópicas significativas, a maioria dos gatos avaliados no estudo exibiu alguma lesão testicular, sendo a degeneração testicular e a fibrose intersticial as mais comuns. Desta forma, destaca-se a importância da histopatologia no diagnóstico de alterações testiculares em animais considerados saudáveis.

The study of testicular lesions in felines is essential in the diagnosis of reproductive diseases, since, the gonads can present important alterations, even when they are macroscopically normal. Thus, the present work aimed to evaluate the main testicular injuries in adult cats submitted to elective orchiectomy, determining the most frequent ones. For this, 25 adult male cats, aged between one and two years, were used. All animals came from the Pet Population Control Program through the Surgical Sterilization Method of the Veterinary Hospital of the Federal University of Uberlândia (HOVET-UFU). After the orchiectomy, the testicles were collected and sent to the Animal Pathology Sector of HOVET-UFU, where they were separated from their respective epididymis. The dimensions of length, height, width, weight, and volume of each testicle were obtained. These were then fixed in 10% formalin for 24 hours, and cleaved in the cranial, middle, and caudal regions. The fragments were submitted to processing for inclusion in paraffin and staining by hematoxylin and eosin. Even without significant macroscopic changes, most cats evaluated in the present study showed some testicular damage, with testicular degeneration and interstitial fibrosis being the most common. Therefore, the importance of histopathology in the diagnosis of testicular alterations in animals considered healthy is highlighted.

Enriquecimento ambiental para gatos em ambiente de internação / Environmental enrichment for inpatient cats / Enriquecimiento ambiental para gatos hospitalizados

Muitas patologias podem acometer felinos, que corriqueiramente determina a necessidade de atendimento veterinário. O ambiente no qual o gato está inserido adquire extrema importância, sendo que na maioria das clínicas e hospitais veterinários em que estes animais são mantidos em internação há condições aquém das ideais. O enriquecimento ambiental, constitui uma ferramenta que busca melhorar a qualidade de vida do animal, possibilitando assim a antecipação da recuperação e consequentemente melhores prognósticos ao animal. Para minimizar um possível nível de estresse que o ambiente de internação pode determinar ao animal, foi realizado um estudo experimental na Clínica Veterinária da Unigran em Dourados - MS, no qual 3 gatos saudáveis (2 machos e 1 fêmea) com idade aproximada de três anos foram mantidos em ambiente de internação para se realizar estudo comportamental dos mesmos por meio de gravações em vídeos e posterior análise utilizando-se etograma. Os vídeos eram efetuados em dois momentos, sendo no primeiro a baia de internação sem enriquecimento ambiental, enquanto no segundo eram introduzidos ítens (caixa de areia, cama e brinquedos) como enriquecimento. O enriquecimento ambiental ajudou de forma moderada alguns animais, na diminuição do tempo despendidos de alguns de seus comportamentos compreendidos na forma de estresse bem como observou-se que os animais de uma maneira geral no momento em que se realizava o manejo de enriquecimento ambiental possuiam maior interação com o ser humano e desta maneira pode-se recomendar o uso de formas que possam tornar o ambiente mais próximo ao encontrado no domicílio do felino.(AU)

Many pathologies can affect felines, which routinely determines the need for veterinary care. The environment in which the cat is inserted is extremely important, and in most veterinary clinics and hospitals where these animals are kept in hospital, there are less than ideal conditions. Environmental enrichment is a tool that seeks to improve the quality of life of the animal, thus enabling the anticipation of recovery and consequently better prognosis for the animal. In order to minimize a possible level of stress that the hospital environment can determine to the animal, an experimental study was carried out at the Unigran Veterinary Clinic in Dourados - MS, in which 3 healthy cats (2 males and 1 female) with an approximate age of three years they were kept in an inpatient environment to conduct a behavioral study of them through video recordings and subsequent analysis using ethogram. The videos were made in two moments, the first being the hospitalization cubicle without environmental enrichment, while the second was introducing items (sandbox, bed and toys) as enrichment. Environmental enrichment helped moderately some animals, in reducing the time spent on some of their behaviors included in the form of stress, as well as it was observed that animals in general at the time when the management of environmental enrichment was carried out had greater interaction with the human being and in this way it can be recommended the use of ways that can make the environment closer to that found in the feline's home.(AU)

Muchas patologías pueden afectar a los felinos, lo que determina de forma rutinaria la necesidad de atención veterinaria. El entorno en el que se inserta el gato es extremadamente importante, y en la mayoría de las clínicas veterinarias y hospitales donde estos animales se mantienen en el hospital, las condiciones no son ideales. El enriquecimiento ambiental es una herramienta que busca mejorar la calidad de vida del animal, posibilitando así la anticipación de la recuperación y consecuentemente un mejor pronóstico para el animal. Con el fin de minimizar un posible nivel de estrés que el entorno hospitalario puede determinar al animal, se realizó un estudio experimental en la Clínica Veterinaria Unigran en Dourados - MS, en el que 3 gatos sanos (2 machos y 1 hembra) con un aproximado Los tres años de edad fueron mantenidos en un ambiente de internación para realizar un estudio de comportamiento de los mismos mediante grabaciones de video y posterior análisis mediante etograma. Los videos se realizaron en dos momentos, el primero fue el cubículo de hospitalización sin enriquecimiento ambiental, mientras que el segundo fue introduciendo elementos (arenero, cama y juguetes) como enriquecimiento. El enriquecimiento ambiental ayudó moderadamente a algunos animales, a reducir el tiempo dedicado a algunas de sus conductas incluidas en la forma de estrés, así como también se observó que los animales en general en el momento en que se realizaba el manejo del enriquecimiento ambiental tenían mayor interacción con el ser humano y de esta forma se puede recomendar que el uso de formas que puedan acercar el entorno al que se encuentra en el hogar del felino.(AU)

Assisted reproductive technologies used in small animal veterinary practice - possibilities, obstacles and future

Assisted Reproductive Technologies (ART) are currently used in animals usually in three main situations: 1. As a form of treatment of subfertility and infertility in females and/or males, 2. As a method to obtain genetically valuable progeny in relatively short time in healthy fertile animals, 3. As a modern smart tool to obtain progeny in endangered animal species in programs of rescue of wild animals threatened extinction. Generally the efficiency of reproductive biotechniques in dogs and cats is lower in comparison to obtained in farm animals and in human. Independently of the aim of their use, there are some techniques, which are better developed in dogs and some others seems to be better developed in cats. It may be assumed that simple, clinical techniques are well elaborated and more frequently used in dogs while more advanced techniques are better developed in cats. The level of effectiveness of ART is conditioned by anatomical and physiological factors specific for species, general demands for their use in veterinary practice and research, and general interest of breeders and scientific community in such activity.(AU)

VCM, RDW-SD e RDW-CV em cães e gatos saudáveis da cidade de Canoas (RS) / MCV, RDW-SD and RDW-CV in healthy dogs and cats from the city of Canoas (RS) / VCM, RDW-SD y RDW-CV em perros y gatos sanos de la ciudad de Canoas (RS)

A Amplitude de Distribuição dos Eritrócitos na automação é medida como RDW-CV (como Coeficiente de Variação) e RDW-SD (como Desvio Padrão), avaliando a variação do volume dos eritrócitos. Embora o RDW-CV seja amplamente utilizado na medicina veterinária como auxílio no diagnóstico da anisocitose, o RDW-SD é raramente utilizado. O estabelecimento dos valores de referência dos três parâmetros poderá auxiliar na diferenciação de algumas anemias e facilitar o diagnóstico das doenças. Foram coletados os dados de 425 cães (240 fêmeas e 185 machos) e 96 gatos (62 fêmeas e 34 machos) saudáveis atendidos no Hospital Veterinário da ULBRA (Canoas/RS), e posteriormente os animais foram divididos em três grupos etários: grupo 1 (3 a 12meses), grupo 2(1 a 8 anos) e grupo 3 (acima de 8 anos). Objetivou-se o estabelecimento de valores de referências para as espécies, assim como a análise de diferença estatística de fêmeas e machos e dos grupos etários para as variáveis estudadas. O programa IBM SPSS® Statistics foi utilizado para as análises estatísticas.

The red blood cell distribution width in automation is measured as RDW-CV (as Coefficient of Variation) and RDW-SD (as Standard Deviation) to assess the variation in erythrocyte volume. Although RDW-CV is widely used in veterinary medicine for the diagnosis of anisocytosis, RDW-SD is rarely used. The establishment of reference values for the parameters may help to differentiate some anemias and facilitate the diagnosis of diseases. Data were collected from 425 healthy dogs (240 females and 185 males) and 96 healthy cats (62 females and 34 males) attended at the ULBRA's Veterinary Hospital (Canoas/RS), and later the animals were divided into three age groups: group 1 (3 to 12 months), group 2 (1 to 8 years) and group 3 (over 8 years). The objective was to establish reference values for the species, as well as to analyze the statistical difference of females and males and of the age groups for the studied variables. The IBM SPSS® Statistics program was used for statistical analysis.

El establecimiento de valores de referencia para los tres parámetros puede ayudar a diferenciar alguna anemia y facilitar el diagnóstico de enfermedades. Se recogieron datos de 425 perros sanos (240 hembras y 185 machos) y 96 gatos (62 hembras y 34 machos) tratados en el Hospital Veterinario ULBRA (Canoas/RS), y posteriormente los animales se dividieron en tres grupos de edad: grupo 1 (3 a 12 meses), grupo 2 (1 a 8 años) y grupo 3 (mayores de 8 años). El objetivo fue establecer valores de referencia para la especie, así como el análisis de diferencia estadística entre hembras y machos y grupos de edad para las variables estudiadas. Para los análisis estadísticos se utilizó el programa IBM SPSS® Statistics.

Colistin resistance profiles and genotypes of Escherichia coli isolates from dogs and cats

Background: Nowadays, antibiotic resistance has become an important problem, posing a serious threat to both human and animal medicine. Colistin is one of the last-resort drugs for the treatment of particularly caused by multidrug resistant bacteria. The aim of this study was to investigate the resistance of Escherichia coli strains against colistin and the presence of colistin resistance genes (mcr1, mcr2 and mcr3) in them. Antibiotyping and genotyping of all strains was also aimed. Materials, Methods & Results: A total of 75 isolates of Escherichia coli from healthy animals (38 dogs and 37 cats) were screened for colistin resistance by cultivation in a screening agar and then microbroth dilution method was performed. Antibiotic susceptibilities of the isolates were determined by KBDDM. The presences of mcr1, mcr2 and mcr3 genes were investigated by PCR. The colistin resistant strains were genotyped by using RAPD-PCR, and antibiotyped based on resistance profiles. In the screening test, 1 strain in cats and 2 strains in dogs were colistin-resistant. However, 18.6% of strains (from 14 cats and 3 dogs) were found as colistin-resistant in the microdilution test. MDR status was 76.31% and 97.29% in dog and cat strains, respectively. The colistin-resistant strains showed 78-100% and 65-90% similarities with respect to their antibiotypes and genotypes, respectively. mcr1, mcr2 and mcr3 genes were not found in any of the strains. Discussion: There is an increase in infections brought on by Gram negative bacteria with various antibiotic resistances in addition to infections brought on by bacteria that are antibiotic-resistant. In order to cure illnesses caused by resistant bacteria, the repurposing of outdated antibiotics may be on the table. Colistin is a crucial antibiotic in veterinary medicine, according to a number of published perspectives, although it should only be administered with caution. However, the discovery of the plasmid-derived mcr1 gene and subsequent reports that this gene has propagated around the world. Escherichia coli strains isolated from companion animals have been found to carry the mcr1 (colistin resistance gene), and possible human-animal cross-contamination has been looked into. The findings demonstrated that mcr1-carrying E. coli might inhabit pets and spread between people and animals. The cat and dog strains used in this investigation had variable colistin resistance rates, which varied between trials. Although no isolates were found to be positive for the mcr1-3 genes in this study, it is believed that colistin resistance, which is determined phenotypically, should not be ignored in terms of spreading both in cat and dog populations as well as in terms of risk to human health, given the possibility that resistance could occur with other different mechanisms. Epidemiological research still uses in vitro antibacterial susceptibility patterns. Our antibiotyping method, which was based on an analysis of several antibiotic resistances, provided quantitative data. Commercial software was utilized to conduct the evaluation. There are no reports or publications that provide quantitative antibiotyping data for E. coli strains in the literature. A popular technique for genotyping different bacterial species is RAPD-PCR. By determining if certain specific genotypes are similar to those of other resistance strains, RAPD-PCR and other genotyping data can be compared with antibiotic resistance profiles to determine the specific risk of treatment resistance in infectious diseases. All organisms that were colistin resistant exhibited multiple antibiotic resistance, and these findings were also related to RAPD genotypes. The findings indicated that colistin-resistant E. coli bacteria could potentially represent a risk to human health and were thought to be transmitted from cats and dogs to humans and vice versa.

Enriquecimiento ambiental para gatos hospitalizados / Environmental enrichment for inpatient cats / Enriquecimento ambiental para gatos em ambiente de internação

Muchas patologías pueden afectar a los felinos, lo que determina de forma rutinaria la necesidad de atención veterinaria. El entorno en el que se inserta el gato es extremadamente importante, y en la mayoría de las clínicas veterinarias y hospitales donde estos animales se mantienen en el hospital, las condiciones no son ideales. El enriquecimiento ambiental es una herramienta que busca mejorar la calidad de vida del animal, posibilitando así la anticipación de la recuperación y consecuentemente un mejor pronóstico para el animal. Con el fin de minimizar un posible nivel de estrés que el entorno hospitalario puede determinar al animal, se realizó un estudio experimental en la Clínica Veterinaria Unigran en Dourados - MS, en el que 3 gatos sanos (2 machos y 1 hembra) con un aproximado Los tres años de edad fueron mantenidos en un ambiente de internación para realizar un estudio de comportamiento de los mismos mediante grabaciones de video y posterior análisis mediante etograma. Los videos se realizaron en dos momentos, el primero fue el cubículo de hospitalización sin enriquecimiento ambiental, mientras que el segundo fue introduciendo elementos (arenero, cama y juguetes) como enriquecimiento. El enriquecimiento ambiental ayudó moderadamente a algunos animales, a reducir el tiempo dedicado a algunas de sus conductas incluidas en la forma de estrés, así como también se observó qu

Many pathologies can affect felines, which routinely determines the need for veterinary care. The environment in which the cat is inserted is extremely important, and in most veterinary clinics and hospitals where these animals are kept in hospital, there are less than ideal conditions. Environmental enrichment is a tool that seeks to improve the quality of life of the animal, thus enabling the anticipation of recovery and consequently better prognosis for the animal. In order to minimize a possible level of stress that the hospital environment can determine to the animal, an experimental study was carried out at the Unigran Veterinary Clinic in Dourados - MS, in which 3 healthy cats (2 males and 1 female) with an approximate age of three years they were kept in an inpatient environment to conduct a behavioral study of them through video recordings and subsequent analysis using ethogram. The videos were made in two moments, the first being the hospitalization cubicle without environmental enrichment, while the second was introducing items (sandbox, bed and toys) as enrichment. Environmental enrichment helped moderately some animals, in reducing the time spent on some of their behaviors included in the form of stress, as well as it was observed that animals in general at the time when the management of environmental enrichment was carried out had greater interaction with the hum

Muitas patologias podem acometer felinos, que corriqueiramente determina a necessidade de atendimento veterinário. O ambiente no qual o gato está inserido adquire extrema importância, sendo que na maioria das clínicas e hospitais veterinários em que estes animais são mantidos em internação há condições aquém das ideais. O enriquecimento ambiental, constitui uma ferramenta que busca melhorar a qualidade de vida do animal, possibilitando assim a antecipação da recuperação e consequentemente melhores prognósticos ao animal. Para minimizar um possível nível de estresse que o ambiente de internação pode determinar ao animal, foi realizado um estudo experimental na Clínica Veterinária da Unigran em Dourados - MS, no qual 3 gatos saudáveis (2 machos e 1 fêmea) com idade aproximada de três anos foram mantidos em ambiente de internação para se realizar estudo comportamental dos mesmos por meio de gravações em vídeos e posterior análise utilizando-se etograma. Os vídeos eram efetuados em dois momentos, sendo no primeiro a baia de internação sem enriquecimento ambiental, enquanto no segundo eram introduzidos ítens (caixa de areia, cama e brinquedos) como enriquecimento.

Pelvic fracture in a cat - precontouring of the plate based on allogenic 3D model and its application

Background: Pelvic fractures are commonly ecountered in cats. The ilium is included in approximately 50% of pelvic fractures in cats. Although conservative management of the pelvic fracture is known to have good prognosis, surgical fixation is recommended for the pelvic fracture with ilial fractures. 3D printing is an accurate digital modeling method by converting two-dimensional (2D) images into 3D model. 3D printing in veterinary medicine has been described in the various orthopedic diseases such angular limb deformities or fractures. The use of 3D model for presurgical planning is helpful to improve the results of complex surgical interventions. The objective of this study is to identify the usefulness of fabricating 3D models based on allogenic 2D data with aid of 3D printer program. Case: A 4-year-old spayed female domestic shorthair cat presented with hindlimb lameness. Radiography revealed left ilial body fracture with multiple fractures including left tuber ischium, pubic symphysis, and bilateral cranial ramuses of pubis. Digital imaging and communication in medicine (DICOM) files of the complete ilium were extracted from a computed tomography (CT) scan of a healthy and castrated male cat of same breed. Volume rendering images were prepared by Slicer program based on DICOM files. After acquired 3D data were converted to STL (Standard Triangulation Language) file for the 3D printing machine, non-fracture involved area was removed except the left ilium using the Meshmixer® software and then data was stored as STL files again. The length of 3D model was adjusted to actual size using 3D printer firmware based on actual size of the ilial length. Subsequently, 3D modelling was performed using 3D printer. The plate was precontoured to conform to the lateral surface of the 3D model. Internal fixation using precontoured plate resulted in accurate bone alignment. The alignment of the ilium remained appropriate throughtout the follow-up period. Complete union was identified 6 months after surgery. Discussion: Although the most common method for the ilial fractures is the application of bone plates to the lateral side of the ilium, bone plate fixation is more challenging in cats owing to the small bone size and small surface area of the fracture sites compared to dogs. Therefore, it is important to make accurate presurgical planning for successful result of a surgery. 3D printing based on actual patient have several limitations including time for complete printing process and additional anesthetic episode to acquire CT images. However, in simple cases, a presurgical CT scan may not be necessary if the plate can be precisely precontured based on the data from the other patient. In this way, the additional financial burden for CT examination also might be reduced. On the other hand, technical difficulty of utilizing hardware and software, and financial availability were another drawback. However, in this current study, most of limitations regarding conventional 3D printing based on actual patient were overcome by the application of the fused deposition modeling (FDM) technology with allogenic data. In the current study, total time for fabrication of 3D model based on FDM technology, was less than 3 h, which are much shorter than the time for conventional 3D printing. The difference of the ilial length between the actual patient and the 3D model was adjusted through the firmware program. Thus, differences of the conformation or size between the 3D model and the ilium of the patient was negligible during the surgery, although 2D images were not acquired from actual patient. Intraoperative contouring of the plate was not required. In conclusion, through presurgical plate contouring by the 3D bone template based on non-patient specific data, successful treatment of the ilial fracture was possible.

Auto-hemoterapia em orquiectomia de cães / Autohemotherapy in dogs' orchiectomy

A orquiectomia consiste na remoção dos testículos e, em animais, pode ser realizada por motivo eletivo ou terapêutico. A cirurgia eletiva faz parte da guarda responsável de cães e gatos e é um dos procedimentos mais realizados na medicina veterinária, incluindo mutirões de castração onde a redução de custos é importante. A auto-hemoterapia (AHT) vem sendo aplicada em animais, inclusive em acupontos, com o intuito de produzir efeitos imunoestimulantes. Neste contexto, este estudo utilizou AHT, durante o período pós-operatório imediato, em acupontos de cães submetidos à orquiectomia eletiva sem a aplicação de antibióticos. Os resultados obtidos foram comparados com dados referentes a outro grupo de animais, os quais foram orquiectomizados e previamente tratados com antibiótico sistêmico. Todos os animais foram acompanhados clinicamente e foram feitos hemogramas nos períodos pré e pós-operatório, assim como o registro de infecções e outras intercorrências relacionadas ao procedimento cirúrgico. Considerando os 20 cães usados no estudo, não houve ocorrência de infecção ou processo inflamatório nos animais após o procedimento cirúrgico. Além disso, alterações hematológicas significativas não foram observadas entre os grupos e entre os períodos pré e pós-operatório de ambos os grupos. Desta forma, conclui-se que a auto-hemoterapia associada à acupuntura pode representar uma alternativa para um protocolo cirúrgico sem antibióticos em cirurgia eletiva de orquiectomia em animais hígidos.

The orchiectomy is the removal of the testicles and, in animals, can be performed due to by elective or therapeutic reasons. Elective surgery is part of the responsible ownership of dogs and cats and is one of the most performed procedures in veterinary medicine, including castration efforts where cost reduction is important. Autohemotherapy (AHT) has been applied in animals, including acupoints, to produce immunostimulatory effects. In this context, this study used AHT, during the immediate postoperative period, in acupoints of dogs submitted to elective orchiectomy without the use of antibiotics. The results obtained were compared to data from another group of animals, which were orchiectomized and previously treated with a systemic antibiotic. All animals were clinically monitored and hemograms were performed during the pre and post-operatory period, as well as the registration of infections and other complications related to the surgical procedure. Regarding the 20 dogs used in the study, there was no occurrence of infection or inflammation in the animals after the surgical procedure. In addition, significant hematologic alterations were not observed between groups and between pre- and post-operatory periods in both groups. Therefore, it is concluded that autohemotherapy associated with acupuncture may represent an alternative for a surgical protocol without antibiotics in elective orchiectomy surgery in healthy animals.

Nova técnica de ligadura do pedículo ovariano e coto uterino em cadela com utilização de duas pinças / Novel technique of ligature of the ovarian pedicle and uterine stump in bitches using two clamps

A ovariosalpingohisterectomia (OSH), que consiste na retirada cirúrgica de ovários, tubas uterinas e útero, é um dos procedimentos cirúrgicos mais realizados em cadelas na rotina veterinária. É utilizado para evitar prenhez indesejada e no tratamento e profilaxia de enfermidades reprodutivas. Classicamente, na técnica de ligadura do pedículo ovariano e coto uterino na OSH em cadelas e gatas, são empregadas três pinças para expor a área de ligadura, por isso, a técnica é conhecida como técnica das três pinças. Sendo assim, o objetivo deste estudo foi propor uma técnica diferente para executar tais ligaduras, reduzindo o tempo do procedimento por meio da diminuição do número de pinças usadas para a exposição dos locais a serem feitas as ligaduras. Desta forma, o experimento foi conduzido com 20 cadelas hígidas submetidas à OSH. Os animais foram divididos em dois grupos: animais submetidos ao procedimento de ligadura pela técnica das três pinças e animais submetidos a ligadura pela técnica proposta neste estudo. A abertura da cavidade abdominal, para expor as estruturas a serem ligadas, foi a mesma para as duas técnicas (laparotomia mediana ventral). Foi mensurado, por meio de cronômetro digital, o tempo despendido na realização de todas as cirurgias. Não ocorreram óbitos e não houve dificuldades na execução das duas técnicas. Além disso, no transoperatório, não houve intercorrências dignas de nota. Os resultados demonstraram que o tempo de execução foi estatisticamente menor para a técnica proposta, indicando a aplicação preferencial deste procedimento para realização de OSH em cadelas.

The ovariohysterectomy (OH), which consists of the surgical removal of ovaries, uterine tubes, and uterus, is one of the most common surgical procedures performed on bitches in the veterinary routine. It is used to prevent unwanted pregnancy and in the treatment and prophylaxis of reproductive diseases. Classically, in the technique of ligation of the ovarian pedicle and uterine stump in OH in bitches and cats, three clamps are used to expose the ligature area, that is why the technique is known as the three clamps technique. Thus, this study aimed to propose a different technique to perform such ligatures, reducing the procedure time by reducing the number of clamps used to expose the sites to be ligated. Therefore, the experiment was carried out with twenty healthy bitches submitted to OH. The animals were divided into two groups: animals submitted to the ligation procedure using the three clamps technique and animals submitted to ligation using the technique proposed in this study. The opening of the abdominal cavity, to expose the structures to be ligated, was the same for both techniques (ventral median laparotomy). The time spent performing all surgeries was measured using a digital timer. There were no deaths and there were no difficulties in performing both techniques. Besides, in the transoperative period, there were no noteworthy complications. The results demonstrated that the execution time was statistically shorter for the proposed technique, indicating the preferential application of this procedure for performing OH in bitches.

Erratum: Investigation of Feline calicivirus infection in cats with upper respiratory tract disease in Diyarbakir, Turkey / Errata: Investigação de infecção por calicivírus felino em gatos com doença do trato respiratório superior na região de Diyarbakir, Turquia

Feline calicivirus is among the most common pathogenic microorganisms in upper respiratory tract disease (URTD) and oral lesions of cats. It leads to stomatitis, oral ulceration, ocular and nasal discharge, conjunctivitis, fever, lameness, anorexia, hypersalivation, pneumonia, respiratory distress, coughing, and depression in infected cats. This study aimed to determine the role of Feline calicivirus (FCV) in cats with the upper respiratory tract disease in the Diyarbakir region, Turkey, to provide treatment for infected cats and contribute to the disease prophylaxis. The study material consisted of 10 cats (control group) considered to be healthy according to the clinical examination and 20 cats with URTD that were not vaccinated against Feline calicivirus infection of different breeds, ages, and genders brought to Dicle University Veterinary Faculty Prof. Dr. Servet SEKIN Polyclinic with URTD. After routine clinical examinations of the animals, oral and conjunctival swabs and blood samples were taken. Hematological and biochemical analyzes of blood samples were performed. Swab samples were analyzed by the polymerase chain reaction (PCR) method for the diagnosis of the agent. Oral lesions, hypersalivation, ocular and nasal discharge, coughing, and breathing difficulties were seen in clinical examinations of cats with URTD. Feline calicivirus was detected in only one cat's conj

Quantification of the collagen fibers of healthy and neoplastic mammary tissue in cats by the Picrossirius Red histochemical method

Although feline mammary carcinoma is not the most prevalent among the species, its aggressive behavior represents a low life expectancy, compared with most undifferentiated types of breast cancer. Tissue stiffness induced by the accumulation of collagen fibers is related to a risk factor for carcinogenesis in healthy women and aggressiveness in those with breast cancer, which can also occur in cats. The objective of this work is to identify the relationship between stromal collagen density and aggressiveness of mammary carcinoma in cats, according to the peripheral and central tissue distribution by the Picrossirius Red histochemical method. Image.J® and MatLab® software were used for digital image processing. The mean values of kurtosis and entropy attributes were ​​grouped into a control group, and low and high-grade carcinoma groups, analyzed with one-way ANOVA and Bonferroni’s multiple comparison test (p <0.01). Interpretation of stromal dynamics is important to evaluate both central and peripheral locations. According to entropy, there was a significant increase in the peripheral density in the carcinoma groups in relation to the control group, which can be justified by blood support. The same can be said of the central region, with a significant gain in collagen fibers from the tumors, indicated by kurtosis. The results suggest the presence of increases in stromal density in mammary carcinomas of cats, regardless of their graduation, and occurring in both regions.

Inverted ovariosalpingohisterectomy technique in cats: advantages and limitations / Técnica de ovariossalpingohisterectomia invertida em gatas: vantagens e limitações

The inverted ovariosalpingohysterectomy (OSH) technique involves initial uterine removal, followed by ovarian disinsertion. The objective of this study was to compare the inverted technique with the traditional technique, characterized by initial removal of the ovaries followed by uterine resection, for evaluating the performance of the inverted OSH technique in cats. For this, 24 healthy, female cats, aged between 7 months and 5 years, with a body condition score of up to 6 points (9-point scale), divided into two equal groups: the traditional technique (TT) and the inverted technique (IT). Procedures were performed by the same veterinarians (surgeon and their assistant) as well as semi-quantitative analysis of the techniques (questionnaire related to the ease of uterine and ovarian manipulation as well as of intestinal and urinary vesicle manipulation) and descriptive qualitative analysis (technical report with the opinion of surgeons and an external evaluator). In addition, the total surgical time and positive pain response were evaluated, indicated by the changes in vital parameters observed by the anesthesiologist during surgery. Inverted technique it promoted greater ovarian exposure, allowing uterine cranial flexion to perform the ligatures, thus facilitating their manipulation, hemostasis, and section of the pedicle. Free the uterus from its ligaments to the abdominal cavity allowed greater mobilization of the conjoint. Both techniques required short operation time (average time of 16’± 1.321’ in the IT group and 15’± 0.525’ in the TT group). The presence of algetic stimulus was similar in the techniques, three animals in each group suffered analgesic rescue.

A técnica de ovariossalpingohisterectomia (OSH) invertida envolve a remoção inicial uterina seguida da desinser-ção ovariana bilateral. O objetivo deste estudo foi comparar a técnica invertida com a tradicional, caracterizada pela remoção inicial dos ovários seguida da ressecção uterina, a fim de avaliar aspectos de execução da OSH Invertida em gatas. Para isso, 24 felinas hígidas, com idade entre 7 meses e 5 anos, com escore de condição corporal até 6 pontos (escala 9 pontos), foram divididas em dois grupos iguais (TT- técnica tradicional e TI- técnica invertida). As cirurgias e anestesias foram efetuadas pelos mesmos médicos veterinários, as técnicas foram avaliadas pelo cirurgião e auxiliar por análises semiquantitativa (questionário com escores relativos à facilidade de manipulação uterina e ovariana, nível de manipulação do intestino e vesícula urinária) e qualitativa descritiva (relatório das técnicas com opinião dos cirurgiões e avaliador externo). Ainda, avaliou-se o tempo cirúr-gico total e a indicação de resposta álgica positiva conforme mudanças nos parâmetros vitais no transoperatório. A OSH inver-tida nos felinos não revelou diferença estatística na análise semiquantitativa quando comparada à técnica tradicional. Porém, promoveu maior exposição ovariana permitindo a flexão cranial uterina, facilitando sua manipulação, hemostasia e secção do pedículo. Ainda, a liberação do útero dos ligamentos à cavidade abdominal permitiu maior mobilização do conjunto. Ambas as técnicas revelaram-se de rápida execução sendo a média de tempo no TI de 16’±1,321’, e no TT de 15’±0,525’. A presença de estímulo álgico foi semelhante nas técnicas havendo resgates analgésicos em três animais de cada grupo.
