Feline chronic gingivostomatitis (FCGS) is a challenge for the veterinary practitioner since its etiology and treatments are still undefined. The present paper investigated the role of the feline immunodeficiency virus (FIV) in the severity of the FCGS. Oral mucosal biopsies obtained from 19 cats with FCGS were divided into two groups according to their FIV serology status. Later, the clinical lesion score was correlated with the histopathological grade of FCGS lesions and the degree of immunostaining in both groups. Most of the animals had significant histological changes; however, no correlation with FIV immunostaining intensity was observed. It was concluded that the presence of FIV infection or the animal’s seropositivity status does not seem to interfere with the severity of clinical signs nor the degree of histopathological changes when compared to the seronegative group.

__________________________________________________________________________Resumo: A gengivo-estomatite crônica é uma patologia oral caracterizada por apresentar lesões inflamatórias crônicas que atinge principalmente o arco glossopalatino. A sua etiologia ainda é desconhecida, mas parece ser multifatorial e apresenta fatores imunomediados. O diagnóstico deve ser baseado na anamnese, exame clínico e análises laboratoriais, devendo a terapêutica ser instituída de acordo com o caso clínico. Este trabalho tem por objetivo apresentar breve revisão de literatura relativa à patogenia, sinais clínicos, diagnóstico e tratamento da gengivo-estomatite crônica felina. Além disso, pretendemos alertar aos médicos veterinários quanto à importância da enfermidade e apresentar as dificuldades diagnósticas e terapêuticas de acordo com o estágio de evolução da doença. Moreover, we intended to warn the veterinary clinicians about the importance of the disease and to discuss about the importance of the disease and present diagnostic and therapeutic difficulties according to the stage of the disease.

PRIMER INFORME DE INFECCIÓN NATURAL POR Platynosomum spp. EN GATO DOMÉSTICO EN EL MUNICÍPIO DE FORTALEZA, CEARÁ, BRASILRESUMEN: El Platynosomum spp. es un trematodo que habita en los ductos biliares y en la vesícula biliar de gatos, que se encuentran en todo el mundo en áreas con climas tropicales y subtropicales. Los gatos que viven en estas áreas se infectan al ingerir los vertebrados inferiores, como los lagartos y las ranas. Muchos casos de platinosomosis son asintomáticos, sin embargo, gatos con infecciones graves pueden presentar ictericia generalizada, vómitos, diarrea mucoide, anorexia, pérdida de peso, depresión y la muerte. Los signos clínicos no son específicos y pueden pasar desapercibidos, dificultando así su control y tratamiento. El objetivo de esta investigación ha sido reportar el primer caso confirmado de esta enfermedad en gato domés-tico ocurrido en el municipio de Fortaleza, Ceará. Por lo tanto, se puede concluir que platinosomosis debe ser investigado en gatos de la región, que presenten señales característicos.

EVANGELISTA, J. S. A. M.; CUNHA, M. G. M. C. M. da. Oclusão de fístula oronasal em gato com uso somente de resina acrílica autopolimerizável. Arq. Ciênc. Vet. Zool. UNIPAR, Umuarama, v. 19, n. 2, p. 101-105, abr./jun. 2016. RESUMO:A fenda palatina é uma comunicação congênita ou adquirida entre as cavidades oral e nasal, permitindo a passagem de alimentos e líquidos entre elas. O diagnóstico é feito por meio do exame físico da cavidade oral, sendo o tratamento baseado em técnicas cirúrgicas. Relata-se um caso bem-sucedido de oclusão de fístula oronasal utilizando somente resina acrílica autopolimerizável em um felino com histórico de espirros frequentes, secreção nasal purulenta crônica, halitose severa, emagrecimento e trauma sofrido há dois anos, que culminara em fratura da sínfise mandibular corrigida no mesmo período por cerclagem com fios de aço. No exame clínico verificou-se secreção nasal muco-purulenta fétida e a presença de uma grande fístula palatina na extensão do palato duro. Encaminhou-se o paciente para realização dos exames pré-cirúrgicos para posterior correção da fistula oronasal com o uso de resina acrílica autopolimerizavel. O procedimento foi bem sucedido visto que o animal deixou de apresentar os sinais clínicos e voltou a alimentar-se normalmente. A técnica mostrou-se eficaz e de fácil execução para correção de fenda palatina traumática de grande extensão em gato, na qual não se utilizou suturas ou flaps, pois os mesmos não eram praticáveis, podendo ser utilizada em substituição a outros métodos convencionais. PALAVRAS-CHAVE: Felino. Fenda palatina. Trauma. ORONASAL FISTULA OCCLUSION IN CAT USING ONLY ACRYLIC RESINABSTRACT: Cleft palate is a congenital or acquired communication between the oral and nasal cavities which can often contaminate the nasal cavity with saliva or food. The diagnosis is made by physical examination of the oral cavity and it is usually treated with surgery. We report a successful case of oronasal fistula occlusion using only acrylic resin in a feline. The patient presented with a history of frequent sneezing, chronic purulent nasal discharge, severe halitosis, weight loss and facial trauma suffered two years ago. The animal had mandibular symphysis fracture that was corrected by cerclage with steel wires. On clinical examinationit was observedthe presence of smelling nasal mucus, purulent secretions and the presence of a large cleft fistula in the extension of the hard palate. The patient was submitted to surgery in order to repair the oronasal fistula using acrylic resin. The surgery was curative eliminating clinical signs. The technique was effective and easy to be performed in this case of a traumatic cleft palate with large deffect in a cat. This technique can be used to replace other conventional methods, mainly in cases that the use of sutures or flaps are not feasible. KEYWORDS: Cleft palate. Feline.

Background: Fibrosing osteomyelitis is a chronic inflammatory process caused by infectious agents that lead to the destruction and replacement of bone tissue by fibroblasts. The diagnosis is based especially on histopathological and bacterial culture. In cases where extensive and irreversible injuries are observed, surgical treatment may be indicated. The objective of this work is to 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 consistency along 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 of the oral cavity, a sample was collected by incisional biopsy, however, the histopathological result was nonspecific. In view of 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 revealed an inflammatory reaction consisting of neutrophils and plasma cells, associated with a large amount of fibrous connective tissue, 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 Pseudomonas aeruginosa, with sensitivity to cefovecin, which was administered to the treatment in doses of 8 mg/kg/SC, every 15 days, for 60 days. After 10 days of the surgery, the patient was able to start the process of swallowing and seizing pasty food.Discussion: Although radiography is a diagnostic method of choice to assess the extent of bone involvement, it hardly allows the distinction between neoplastic processes and osteomyelitis. Thus, in addition to the cranium radiographic examination, that revealed signs of proliferative osteopathy with irregular contours in branch and body topography of the left mandible were required biopsy and bacterial culture. After mandibulectomy, difficulty in retracting the tongue and anorexia were observed in the first days. Despite that, from the 12th day on, there was an improvement in food seizure, with the return to voluntary feeding. Mandibulectomy is indicated in cases where extensive and irreversible lesions are observed, although excision of the caudal mandible to the third or fourth premolar tooth is not recommended, because it compromises the sublingual musculature, with fall of the tongue and loss of function apprehension. In the present case, the caudal portion of the right mandibular branch was maintained, which facilitated the return of spontaneous feeding. The tissue removed was necessary to perform a microbiological culture with antibiogram, essential to determine the possible etiologic agent and choosing antimicrobial drugs. For the treatment of P. aeruginosa infection, cefovecin was prescribed due to the dosage and route of administration that collaborate with the mandibular surgery, once that the oral treatment is more difficult. Post-surgical complications related to mandibular resection, such as anorexia and difficulty in grasping food, are common. However, in the present case, the patient had an adequate reestablish after 15 days. Therefore, hemimandibulectomy is effective in treating fibrosing osteomyelitis, with maintenance of the patient's ingestive function.

Objectives The purpose of this study was to evaluate the correlation between clinical aspects and urethral lesions with reproductive status and age at neutering in obstructed male cats. Methods All cats with compatible signs of urethral obstruction (UO) treated at the Veterinary Hospital of the Federal Rural University of Pernambuco from 2019 to 2021 were divided into three groups according to their reproductive status: intact; prepubertal neutered; and post-pubertal neutered. Cats with compatible signs of UO were selected for further analysis. Age, clinical signs, age at neutering and age of the first obstructive event were documented. Cats with recurrent obstructive urinary signs or urethral trauma that made catheterization impossible were referred for perineal urethrostomy. The morphology of the excised penises was assessed by histopathological analysis. Results Of 84 cats with signs of UO included in this study, 28.6% were classified as intact, 28.6% as prepubertal neutered and 42.8% as post-pubertal neutered. Intact cats had a significantly earlier onset of UO compared with prepubertal and post-pubertal neutered cats, as seen by the age at obstruction (3.6 vs 5.7 and 5.5 years, respectively). Similar clinical signs and histopathological lesions were observed in all groups. The main clinical signs observed were stranguria, hematuria and pollakiuria. All cats had some degree of injury in the penile urethra. The most common lesions were hemorrhage, fibrosis and congestion. Conclusions and relevance It appears that intact cats had an earlier onset of UO than neutered cats, regardless of age at neutering. Urethral histopathological lesions and clinical signs were similar in both groups. Pediatric neutering represents a useful tool in the control of abandoned and stray animals and the consequent dissemination of zoonoses, thus having a positive impact on public health.
