RESUMO

Background: Canine atopic dermatitis (CAD) is a chronic and inflammatory disease present in veterinary dermatologicalpractice. The inflammation in CAD is triggered by environmental allergens and skin microorganisms, which are responsiblefor the worsening of cutaneous lesions. This continuous activation of skin inflammatory process can induce the productionof free radicals that also contribute to cellular damage and ultimately leads to changes in blood parameters in dogs withCAD. Although there are reports of inflammatory parameters in CAD, there are a lack of studies correlating skin lesions,blood leukocytes and oxidative stress. Based on that, this study aimed to evaluate the integumentary and systemic inflammatory response in dogs with atopic dermatitis.Materials, Methods & Results: Dogs with confirmed diagnosis of canine atopic dermatitis (n = 10) were divided in twogroups according to CADESI-IV: AI, with CADESI between 0-10, AII, with CADESI between 10-34, and control group (n= 5). Blood-biochemical and histological analysis were performed to access systemic and cutaneous inflammatory response.AII group tended to higher neutrophil and eosinophil counts, as well as neutrophil/lymphocyte ratio (NLR) when comparedto AI. The albumin was lower in AII compared to AI and control (P < 0.05), while total bilirubin and malondialdehyde(MDA) did not differ between groups. NLR (r = 0.64 and P = 0.04) and MDA (r = 0.54 and P = 0.1) were positively correlated with CADESI, while albumin was negatively correlated with CADESI (r = -0.79 and P = 0.005). Histopathologicalanalysis revealed a larger number of neutrophils, macrophages and mast cells in AI and AII than in control group (P < 0.05).Discussion: In this study it was possible to evaluate the systemic and cutaneous leukocyte dynamics in CAD.

RESUMO

A dermatite atópica canina (DAC) é uma dermatopatia inflamatória, crônica e pruriginosa que afeta indivíduos geneticamente predispostos, sendo comumente associada à produção de anticorpos do tipo IgE. O presente relato objetivou descrever um caso de DAC, evidenciando seus sinais clínicos, diagnóstico e tratamento. Foram realizados teste com lâmpada de Wood, raspado profundo de pele, imprint cutâneo, cultura fúngica e bacteriana, citologia de ouvido, exame sorológico para leishmaniose visceral canina (LVC) e teste de sensibilidade a alérgenos. O paciente apresentava uma série de lesões dermatológicos disseminadas acompanhadas de prurido intenso, onde pode-se observar presenças de infecções secundárias por bactérias e leveduras fúngicas. Dessa forma, optou-se por tratamento tópico com shampoo a base de clorexidina 2% associado a miconazol 2,5% e uso de creme hidratante. Para otite bilateral, prescreveu-se solução otológica de ciclopirox olamina 1% e ácido glicirrízico 0,5%. Após resposta negativa ao tratamento inicial, introduziu-se o uso oral de prednisolona associado à hidroxizina e logo depois a ciclosporina, ocorrendo um controle do quadro. Embora várias alternativas terapêuticas estejam disponíveis, a cura ainda não é possível, sendo o controle do quadro lesional a melhor abordagem de tratamento.

The canine atopic dermatitis (CAD) is an inflammatory skin disease, chronic itchy that affects genetically predisposed individuals, being commonly associated with production of IgE antibodies. The aim of this study was to describe a case of CAD, evidencing its clinical signs, diagnosis and treatment. A Wood lamp, skin deep scraping, skin imprint, fungal and bacterial culture, ear cytology, serological examination for canine visceral leishmaniasis (LVC) and allergen sensitivity test were performed. The animal presented a series of disseminated dermatological lesions accompanied by intense pruritus, where it is possible to observe presences of secondary infections by bacteria and yeasts fungi. Thus, it was decided to topical treatment with shampoo chlorhexidine base 2% associated with miconazole 2.5% and use moisturizer. For bilateral otitis, otologic solution of cyclopirox olamine 1% and glycyrrhizic acid 0.5% was prescribed. After negative response to the initial treatment, the oral use of prednisolone associated with hydroxyzine and soon after cyclosporine was introduced, and clinical control was performed. Although several therapeutic alternatives are available, cure is still not possible, and lesion control is the best treatment approach.

RESUMO

As farmacodermias podem ser definidas como reações adversas em pele, mucosas e anexos, tendo, por vezes, caráter imunomediado. O diagnóstico baseia-se na avaliação clínico-laboratorial do paciente, envolvendo uma pesquisa acerca de fatores relacionados ao uso do fármaco e seus efeitos adversos. Na medicina veterinária, são escassos os relatos de reações farmacodérmicas. Logo, o objetivo do presente trabalho é relatar uma reação adversa após terapia otológica em cão. Foi atendido um paciente canino, fêmea, 02 anos de idade, com histórico de prurido auricular bilateral com evolução de três semanas. Na ocasião, foi realizado exame citológico auricular, evidenciando presença de elevada quantidade de células leveduriformes e cocos, além de células descamativas. Optou-se, então, por terapia à base de solução otológica composta por Gentamicina, Clotrimazol, Betametasona e Benzocaína. O quadro clínico evoluiu de forma satisfatória até o décimo dia de tratamento, quando a paciente apresentou intenso eritema e secreção melicérica bilateralmente. Repetiu-se o exame citológico, assim como realizou-se cultura de bactérias aeróbicas, sendo evidenciado em tais exames um infiltrado inflamatório piogranulomatoso, com pouca presença de conteúdo bacteriano e fúngico, corroborando com os achados da cultura bacteriana. Diante da suspeita de farmacodermia, procedeu-se com a troca de todos os compostos terapêuticos, tendo a paciente evoluído de forma satisfatória até o término do tratamento. Por tratar-se ainda de uma solução otológica composta, não se pode atribuir a causa da reação a especificamente um dos compostos. Contudo, reforça-se a necessidade de conscientização do médico veterinário acerca da identificação e adequada intervenção nas reações adversas medicamentosas, assim como espera-se sua contribuição científica na difusão dessas informações.

Pharmacodermia can be defined as adverse reactions in skin, mucous membranes and appendages, sometimes having immunomediated character. The diagnosis is based on the patient clinical-laboratorial evaluation, involving a research about factors related to the drug use and its adverse effects. In veterinary medicine, reports of pharmacodermic reactions are scarce. Therefore, the aim of the present study is to report an adverse reaction after otologic therapy in dogs. A 2-year-old female canine patient with a history of bilateral auricular pruritus with a three-week course was attended. At the time, auricular cytology was performed, evidencing the presence of high numbers of yeast cells and cocci, as well as desquamative cells. It was then opted for otologic solution composed of Gentamicin, Clotrimazole, Betamethasone and Benzocaine. The clinical presentation progressed satisfactorily until the tenth day of treatment, when the patient presented intense erythema and meliceric secretion. Cytological examination was repeated, as well as culture of aerobic bacteria. A piogranulomatous inflammatory infiltrate with low bacterial and fungal content was evidenced in these examinations, corroborating with the findings of the bacterial culture. Faced with the suspicion of pharmacodermia, all therapeutic compounds were exchanged, and the patient progressed satisfactorily until the end of the treatment. Because it is still a composed otological solution, the cause of the reaction cannot be attributed to specifically one of the compounds. However, there is a need to raise the awareness of the veterinarian about the identification and appropriate intervention in adverse drug reactions, as well as his scientific contribution to the dissemination of this information.

RESUMO

O linfoma é uma forma de apresentação do distúrbio linfoproliferativo, em que o tumor se origina em um órgão hematopoiético sólido, como o linfonodo. É considerada uma neoplasia de maior incidência em cães e gatos. O trabalho tem como objetivo apresentar um relato de caso sobre um linfoma multicêntrico, com abordagem clínica e laboratorial. Um cão sem raça definida, foi atendido no Hospital Veterinário da Universidade Estadual do CEARÁ (UHV-UECE), apresentando hematúria e uma discreta linfadenomegalia no exame físico. Foram solicitados hemograma completo (HC), análise de bioquímica sérica, sumário de urina e exame ultrassonográfico (US). As alterações no hemograma foram anemia normocítica normocrômica e trombocitopenia. A análise dos exames de bioquímica sérica revelou um aumento na enzima aspartato amino-transferase (AST). No sumário de urina (SU), observaram-se alterações das características físicas e da sedimentoscopia. O exame ultrassonográfico mostrou alterações de ecogenicidade na bexiga, próstata, testículo e baço. Houve piora do quadro clínico do animal, com perda de peso e aumento evidente dos linfonodos. Um exame citológico foi realizado com aspirado de linfonodos, que apresentou configuração celular compatível com linfoma; sendo também encontradas células neoplásicas no esfregaço de sangue periférico, no hemograma. Diante dos achados e do agravamento do quadro clínico, o animal veio a óbito.

Lymphoma is a form of presentation of the lymphoproliferative disorder which the tumor originates from a solid hematopoietic organ such as the lymph node. It is considered one of the neoplasia of higher incidence in dogs and cats. This paper aims to present a case report on a multicenter lymphoma with a clinical and laboratory approach. A dog without defined breed, at the Hospital Veterinário da Universidade Estadual do CEARÁ (UHV-UECE) presenting hematuria and a discrete lymphadenomegaly on physical examination. Complete blood counts (HC), serum biochemical analyzes, urine summary and ultrasound examination were requested. Changes in the hemogram were normocyclic normocytic anemia and thrombocytopenia. Biochemical analysis revealed an increase in asparate amino transferase (AST). The urine summary (SU) showed changes in physical characteristics and sedimentation. Ultrasound examination (US) showed changes in the bladder, prostate, testis echogenicity and the spleen’s size. There was worsening of the animal's size over time with progression of weight loss and evident enlargement of the lymph nodes. A cytology was performed through a lymph node aspirate which had a lymphoma compatible cell configuration and neoplastic cells were also found in the hemogram peripheral blood smear. The animal died with deterioration of the clinical picture.

RESUMO

O tumor venéreo transmissível (TVT) é uma neoplasia de células redondas maligna se contagiosas, comum em cães. Uma abordagem clínica e laboratorial precisa e rápida é importante para um melhor prognóstico do animal. Portanto, o trabalho tem como objetivo apresentar um relato de caso sobre TVT, na genitália externa de uma cadela prenhe. Uma cadela sem padrão racial definido e sem idade definida deu entrada no Hospital Veterinário Sylvio Barroso Cardoso (HVSBC), apresentando secreção vaginal escura e fétida segundo a queixa da proprietária. Durante o exame físico observou-se que a vulva estava edemaciada e avermelhada, sem estímulo doloroso ao toque ou alteração de temperatura e havia múltiplos nódulos na região. Além disso, as mucosas estavam hipocoradas. Foi prescrito para o animal um hemograma completo, mais dosagens bioquímicas (creatinina e alanina amino transferase), exame citológico e ultrassonografia abdominal total. No hemograma o animal apresentou anemia normocítica e hipocrômica, moderada anisocitose e hipocromia, rouleaux eritrocitário e trombocitopenia. As dosagens bioquímicas não tiveram alterações de relevância clínica. O exame ultrassonográfico revelou que o animal estava em 45 dias de gestação. A citologia foi realizada através do método de imprint em que se obteve3 lâminas, baseado no padrão celular observado constatou-se que se tratava de um TVT. O animal foi tratado com aceturato de diminazeno e complexos vitamínicos, e esperou-se para iniciar o tratamento quimioterápico com sulfato de vincristina apóso parto. O animal pariu 7 filhotes saudáveis. Após 3 semanas de tratamento a cadela apresentou remissão da neoplasia.

Transmissible venereal tumor (TVT) is a malignant, common and contagious round cell neoplasm in dogs. A precise and rapid clinical and laboratorial approach is important for a better prognosis of the animal. Therefore, the work aims to present a case report on TVT in the external genitalia of a pregnant bitch. A bitch with no defined racial pattern and no definite age was admitted to the Veterinary Hospital Sylvio Barroso Cardoso (HVSBC) presenting dark and fetid vaginal secretion according to the owner's complaint. During the physical examination it was observed that the vulva was swollen and reddish, without painful stimulation to the touch or change of temperature and there were multiple nodules in the region. In addition, the mucous membranes were pale mucosa. Complete blood count plus biochemical measurements (creatinine and alanine amino transferase), cytological examination and total abdominal ultrasonography were prescribed for the animal. In the hemogram the animal had normocytic and hypochromic anemia, moderate anisocytosis and hypochromia, erythrocyte rouleaux and thrombocytopenia. Biochemical dosages did not change in clinical relevance. Ultrasound examination revealed that the animal was at 45 days of gestation. Cytology was performed by the imprint method and 3 samples were obtained, and based on the observed cellular pattern, it was found that it was a TVT. The animal was treated with diminazene aceturate and vitamin complexes, and was expected to initiate chemotherapy with vincristine sulfate after delivery. The animal gave birth to 7 healthy puppies. After 3 weeks of treatment, the dog had remission of the neoplasia.

RESUMO

Canine visceral leishmaniasis (LVC) is a disease caused by protozoans of the genus Leishmania, patients affected can present a diversity of clinical symptoms, where the main are: slimming, alopecia, Onychogryphosis and dermatitis. However unconventional signs may be linked to this disease. In this sense the purpose of this work is to report a case of LVC with unconventional signs of the disease. The occurs with a Yorkshire dog that was attended with complaint of pruritus and formation of nodules in the flank region, initially the clinical suspicion was of allergic reaction with fungal dermatitis. After the completion of the complementary exams (Cytopathological, blood count, ALT dosages, creatinine and skin scraping for direct examination) was diagnosed LVC from the observation of Amastigota in Cytopathological. With this result we emphasize the attention to the clinical demonstrations in LVC and the importance of complementary exams such as cytology to quick and accurate diagnostics.
