Clinical and epidemiological features and impact of life habits in canine atopic dermatitis in Fortaleza, Brazil / Achados clínicos e epidemiológicos e impacto do estilo de vida na dermatite atópica canina em Fortaleza/Brasil

Canine atopic dermatitis (cAD) is a worldwide allergic skin disease. The affected dog population can show different clinical patterns according to geographic region, and a lack of studies in Brazil is observed. Therefore, the aim of the present study was to assess the clinical and epidemiological data of cAD in dogs treated in a private clinical practice in Fortaleza, a city located in the Northeast Region of Brazil. cAD was diagnosed in 35% of dogs, being Shih-tzu and Poodle the most affected breeds. Paws and ears were frequently injured sites. Almost 50% of atopic dogs were diagnosed with superficial pyoderma and 36% with cutaneous malasseziosis. Atopic dogs with outdoor habits were less likely to develop cutaneous malassezial infection, and with routine ear, cleaning habits were less likely to develop bacterial otitis externa. In conclusion, canine atopic dermatitis is a prevalent disease in private clinical practice in Fortaleza, and lifestyle habits can be considered a risk factor for cutaneous malasseziosis infection and bacterial otitis externa in atopic dogs.

A dermatite atópica canina (DAC) é uma doença alérgica cutânea de ocorrência mundial. A população canina acometida pode apresentar diferentes padrões clínicos de acordo com a região geográfica e observa-se uma carência de estudos no Brasil. Portanto, o objetivo do presente estudo é avaliar os dados clínicos e epidemiológicos da DAC em cães atendidos em uma clínica privada em Fortaleza, cidade localizada na Região Nordeste do Brasil. A DAC foi diagnosticada em 35% dos cães, sendo Shih-tzu e Poodle as raças mais acometidas. As patas e as orelhas foram locais frequentemente afetados. Quase 50% dos cães atópicos foram diagnosticados com piodermite superficial e 36% com malasseziose cutânea. Cães atópicos com hábitos ao ar livre foram menos propensos a desenvolver malasseziose cutânea e com hábitos rotineiros de limpeza auricular foram menos propensos a desenvolver otite externa bacteriana. Em conclusão, a dermatite atópica canina é uma doença prevalente na prática clínica privada em Fortaleza e os hábitos de vida podem ser considerados como um fator de risco para infecção por malasseziose cutânea e otite externa bacteriana em cães atópicos.

Canine atopic dermatitis: systemic immunomodulatory protocol based on clinical phenotype / Dermatite atópica canina: protocolos imunomodulatórios sistêmicos baseados no fenótipo clínico

Canine atopic dermatitis (cAD) is a multifactorial allergic disease associated with immune dysfunction and abnormal skin barrier. Several immunological mediators play a role in its pathogenesis. Such molecules are produced by the activation of T helper lymphocytes (Th) through polarization to Th1 and/or Th2, which contributes to different lesion patterns. Acute lesions are mediated by an activation of the Th2 cytokine axis, which clinically induces erythema and pruritus. Conversely, in chronic injuries a mixed immune response of Th1/Th2 cytokines occurs, leading to hyperpigmented and lichenified skin. The clinical understanding of these patterns and the mode of action of immunomodulators are crucial for the best clinical management of the atopic patient. In this context, this review discussed the role of the immune response and the immunomodulatory drugs in dogs with atopic dermatitis and suggested a therapeutic protocol based on clinical phenotype. Based on the evidences showed in this review, it is considered appropriate to use immunomodulatory drugs that target cytokine spectrum related with the clinical phenotype of cAD.

A dermatite atópica canina (DAC) é uma doença alérgica multifatorial associada à disfunção imune e barreira cutânea anormal. Vários mediadores imunológicos desempenham um papel na sua patogênese. Tais moléculas são produzidas pela ativação de linfócitos T auxiliares (Th) por meio da polarização para Th1 e/ou Th2, o que contribui para diferentes padrões de lesão. Lesões agudas são mediadas pela ativação do eixo de citocinas Th2, que clinicamente induz eritema e prurido. Por outro lado, nas lesões crônicas ocorre uma resposta imune mista de citocinas Th1/Th2, levando à pele hiperpigmentada e liquenificada. O entendimento clínico desses padrões e o modo de ação dos imunomoduladores são cruciais para o melhor manejo clínico do paciente atópico. Esta revisão visa discutir o papel da resposta imune e das drogas imunomoduladoras em cães com dermatite atópica e sugerir um protocolo terapêutico baseado no fenótipo clínico. Baseado nas evidências apresentadas nessa revisão, é considerado apropriado utilizar drogas imunomoduladoras que abrangem o espectro de citocinas relacionadas ao fenótipo clínico da DAC.

Técnica de massagem relaxante como ferramenta para melhorar a relação humano-animal e os parâmetros de bem-estar animal / The relaxing massage technique as a new tool to improve the human/animal relationship and the animal welfare parameters

O manejo aversivo de espécies de produção pode ter graves consequências na produtividade, reprodução e bem-estar animal, sendo necessários estudos que visam um bom relacionamento humano-animal (RHA), por meio do toque suave, como uma tentativa de tornar este manejo mais benéfico para seres humanos e animais. Nesse sentido, a massagem feita com as mãos constitui uma nova proposta para melhorar o RHA envolvendo ruminantes domésticos. Sendo assim, os objetivos desta revisão são: (1) compreender a importância de um bom relacionamento entre humanos e ruminantes, incluindo a interação com toque; (2) descrever o impacto da massagem sobre diversos parâmetros relacionados à fisiologia, aos estados emocionais e aos comportamentais em humanos e animais; e (3) propor o uso da técnica Stroking em ruminantes domésticos, como forma de incentivar produtores e tratadores a utilizarem a massagem como um método alternativo para melhorar o RHA. Sabe-se que diferentes estudos e protocolos mostraram a importância do toque na promoção de um bom RHA, além dos diversos impactos da massage. Ainda, ao observar que cabras massageadas com a técnica Stroking apresentaram comportamentos positivos, como lambidas na massagista, constata-se que o incentivo ao estudo da modulação de outros parâmetros, como fisiológicos, zootécnicos e psicológicos, em ruminantes domésticos massageados, é necessário. Assim, a aplicação da massagem relaxante, como uma nova ferramenta para a melhora da interação humano-animal envolvendo ruminantes domésticos, é uma proposta que visa criar uma maior proximidade com os animais, possivelmente influenciando a forma como produtores e cuidadores percebem esses seres sencientes.

The aversive management of farmed species may present serious consequences on productivity, reproduction, and animal welfare. Thus, studies that aim at a good human-animal relationship (HAR) and apply gentle touch, as an attempt to make this management more beneficial for humans and animals are required. In this sense, massage with bare hands is a new proposal to improve HAR with domestic ruminants. Therefore, the objectives of this review are: (1) understand the importance of a good relationship between humans and domestic ruminants, including the interaction of touch; (2) describe the impact of massage on various parameters related to physiology and emotional and behavioral states in humans and animals, and (3) propose the use of the Stroking technique (relaxing massage) in domestic ruminants as a mean to encourage producers and caretakers to use massage as an alternative method to improve HAR. Different studies and protocols have shown the importance of touch in promoting a good HAR, in addition to the various impacts of massage on humans and animals. By demonstrating that goats massaged with the Stroking technique showed positive behaviors like licking the masseur, the importance of encouraging the study of the modulation of other topics such as physiological, zootechnical, and psychological parameters in massaged domestic ruminants is highlighted. Thus, the application of relaxing massage, Stroking, as a new tool for improving human-animal interaction with domestic ruminants is a proposal that aims to create a closer relationship with animals, possibly influencing the way producers and caregivers perceive these sentient beings.

Successful treatment and management of canine ehrlichiosis-leishmaniosis-heartworm comorbidity

Background: Canine vector borne diseases (CVBD) are common in tropical countries where the climate favors arthropods abundance. Comorbidity with one or more CVBD are reported as clinical complication and worsen prognostic. Canine visceral leishmaniosis (CanL) is an endemic zoonotic disease in Brazil caused by Leishmania infantum, with several restrictions to canine treatment and suggestion of reservoirs euthanasia for disease control. Heartworm (HW) is a helminthic disease caused by Dirofilaria immitis infection in dogs. It is a chronic heart disease, which can lead to death by congestive heart failure. Canine ehrlichiosis (CE) is caused by Ehrlichia canis bacterial infection with a zoonotic potential and fatal to dogs in acute and chronic presentations. Exposed the above, this study aims to describe a successful treatment and management of a dog with CanL, CE, and HW comorbidity. Case: A 3-year-old male uncastrated black Labrador dog, weighing 35 kg, was admitted to the veterinary clinic due to immunochromatographic CanL positive test performed by municipal zoonosis control center active surveillance. Clinical exam showed a mild shedding, intermittent eye white/yellow discharge and popliteal lymph nodes enlargement. After positive for CanL, veterinary requested more laboratorial exams. IFAT and ELISA were positive for CanL, blood smear showed presence of microfilaria, and bone marrow cytology showed Ehrlichia spp. morulae and microfilaria. Initial treatment prescribed was oral doxycycline, omeprazole, ranitidine, and domperidone for 30 days, and allopurinol and ivermectin until further recommendation. Additionally, repellent collar, repellent spray and vitamin supplement was indicated. After first month, marbofloxacin for 30 days and three doses of immunostimulant drug were administrated. After three months of treatment, dog still positive for heartworm, ehrlichiosis, and CanL. Doxycycline protocol was repeated. Dog became consistently negative for all pathogens one year later with persistent thrombocytopenia but without clinical signs, ergo allopurinol and ivermectin were discontinued. After 4 years of follow up, the animal had an acute pancreatitis and died, with unremarkable total blood count and negative for all pathogens. Discussion: CVBD coinfections are commonly reported as worsen prognostic in endemic regions. The pathogens reported here share a host immunomodulation competence. L. infantum and Ehrlichia spp. downregulates Th1 response, whereas D. immitis increase as Th2 profile. The therapeutic protocol was iniciated by staging CanL. Since the patient had clinical signs, allopurinol was prescribed as a well-established drug for CanL. Marbofloxacin was added due to its high safety drug in clinical improvement of infected dogs with and without renal disease and in vitro effectiveness against L. infantum. Domperidone was used to promote Th1 cytokine profile as INF-γ, IL-2, IL-12, and TNF-α. We used an immunostimulant protocol to favor polarization to the Th1 profile comprised by 30 days of domperidone protocol followed by a vaccine and an immunomodulator. Doxycycline was used successfully for Ehrlichia spp. and HE clearance after 2 treatment courses and 1 year of ivermectin every 15 days. The animal presented intermittent coughing episodes on the first treatment course, but no medical intervention was needed besides exercise restriction. Our report shows the successful management of one dog with CanL, CE and HE comorbidity. This success was possible due to early detection and good therapeutic choice.(AU)

Relationship between PD-L1 expression and tumor-infiltrating lymphocytes in canine mammary tumor

Background: Studies pointed out that the tumor-infiltrating lymphocytes (TILs) have considerable importance in caninemammary tumor (CMT). On the other hand, cancer cells sometimes find ways to use immune checkpoint proteins as ashield to avoid being identified and attacked by the immune system as programmed death 1 ligand 1 (PD-L1). In this study,it was investigated the relationship between PD-L1 expression, stromal tumor-infiltrating lymphocytes (TILs) in caninemammary tumor (CMT), and the association with clinical and pathological characteristics of the tumors.Materials, Methods & Results: PD-L1 expression and TILs were assessed in 23 female dogs with CMT. The tumors weregrouped into simple carcinoma (CA, n = 8) and complex carcinoma (CC, n = 15). Stromal TILs were assessed using twothresholds as TILs-Low representing < 50% of infiltrate within stromal area and TILs-High representing ≥ 50% of stromalarea. Clinicopathological data of CMT was characterized according to key parameters, as well as survival rates. TILs evaluation within tumor stroma revealed that 65.2% (n = 15) of tumors had TILs-Low. PD-L1 expression and stromal TILs weresignificantly associated (P = 0.009). PD-L1 expression was observed in 39% (n = 9) of all tumors of which 17.4% (n = 4)were from CA group and 21.7% (n = 5) were from CC group. PD-L1 expression within TILs was observed in 39% (n =9) of the tumors. PD-L1 in malignant epithelium was present in all lymph node metastasis (n = 5). PD-L1 was associatedwith involvement of regional lymph nodes (P = 0.034). Survival curves demonstrated TILs-Low had higher (P = 0.010)overall survival (OS) compared with TILs-High, and PD-L1+ and PD-L1– (P = 0.06) did not differed. The clinicopathological variables significantly correlated with OS by univariate analysis were the histological grade (P = 0.009), lymphnode involvement (P = 0.004), stromal...

Analysis of systemic and cutaneous inflammatory immune response in canine atopic dermatitis

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. Skin inflammation induces the production of chemotactic molecules contribute to neutrophil outflow from blood vessel toward the...

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

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

Leukocytes and albumin in canine leishmaniasis

Canine Leishmaniasis (CanL) is a multisystemic and chronic inflammatory disease characterized by nonspecific clinical manifestations. In CanL, inflammatory cells and chemical mediators released in response to the parasite play a role in disease development and progression. Alterations on hematological parameters have been documented in CanL. These changes can also be assessed in relation to systemic inflammation caused by this disease. The circulating leukocyte counting, such as neutrophils, as well as the albumin level, are considered direct indicators of an inflammatory host environment. Several studies point to the use of biomarkers on the assistance in diagnosis and prognosis of several canine pathologies. The present study investigated the Neutrophils to Lymphocyte Ratio (NLR), Albumin to Globulin Ratio (AGR), and Neutrophils to Albumin Ratio (NAR) on systemic inflammatory response induced by Canine Leishmaniasis (CanL). For this purpose, adult dogs with confirmed diagnosis to CanL were divided into symptomatic (SD, n = 33) and asymptomatic (AD, n = 20) dogs for L. infantum and control dogs (CD, n = 20). Routine hematological and biochemical parameters were determined in blood samples using a veterinary automatic hematology and biochemical analyzers. Asymptomatic dogs (AD) had a higher number of white blood cells and neutrophils (16.48 ± 4.93; 13.41 ± 3.60, respectively) in relation to symptomatic dogs (SD) (13.54 ± 5.13; 10.42 ± 3.69, respectively) (P = 0.015 and P < 0.0001, respectively). Neutrophils to Lymphocyte Ratio (NLR) was higher in dogs with leishmaniasis (9.45 ± 3.76) than in healthy dogs (3.39 ± 1.19) (P < 0.0001). Serum total proteins (STP) and globulins increased in CanL, while albumin and AGR decreased in CanL, when compared to CD and references values to canine species. Neutrophils to Albumin Ratio (NAR) was higher in AD and SD (5.02 ± 1.14; 4.79 ± 1.07, respectively) when compared to CD (2.36 ± 0.55) (P < 0.0001). As reported in scientific researches, dogs with Leishmaniasis present alterations in circulating cell counts. Based on these data, we decided to expand this information using the NLR as a parameter in an attempt to better clarify the changes in these cells in CanL. We observed that NLR was increased on CanL in relation to healthy dogs, which could be a consequence of relative neutrophilia rather than lymphopenia. Neutrophils to Lymphocyte Ratio (NLR) is a biomarker that conveys information about inflammatory conditions. An elevated NLR can reflect an upregulated innate immune response, since neutrophils are effector cells of innate immunity and are involved in several acute and chronic inflammatory processes. Albumin is an acute phase protein that is considered an immune-inflammatory biomarker, which can be found reduced systemically in progressive inflammatory response. Serum total proteins (STP) and globulins were increased in CanL. These data are already well documented in CanL, which serum globulins are mainly associated with the increase of acute phase proteins, cytokines, and increase of specific antibodies to Leishmania infantum. Our results showed neutrophilia with hypoalbuminemia in CanL. So, in an attempt to assess the relationship of these two available markers, we used NAR calculation in order to evaluate the changes induced by CanL. In this study NAR was higher in CanL when compared to control dogs. Thus, our data indicate that NLR and NAR could be used as biomarkers in veterinary medical clinics in order to assess inflammatory profile in CanL, mainly in asymptomatic dogs. These parameters obtained from routine blood tests might be useful as cost-effective, easily accessible and helpful markers in order to distinguish the inflammatory response intensity in CanL.(AU)

Impact of massage on goats on the human-animal relationship and parameters linked to physiological response / Impacto da massagem em cabras na relação homem-animal e parâmetros relacionados à resposta fisiológica

Considering the benefits that massage can promote, this research aimed to apply the stroking massage in five adult goats (G1-G5) assessed in group and individually for ten days. Parameters related to massage, immune system, physiology and behavior of goats were observed. There was only significant difference (P 0.05) regarding behavior expressed in the presence of the masseur in G4 and G5, between week 1 and 2. Most goats accepted massage, except G2, with greater demonstrations of positive than negative behavior towards the masseur. Therefore, stroking massage promoted positive interactions between the masseur and goats, and should be explored as an alternative method to those existing in improving the relationship between humans and farm animals.(AU)

Considerando os benefícios que a massagem pode promover, este trabalho teve como objetivo aplicar a massagem do tipo stroking em cinco cabras adultas (G1-G5) avaliadas em grupo e individualmente por dez dias. Parâmetros relacionados à massagem, sistema imunológico, fisiologia e comportamento das cabras foram observados. Houve apenas diferença significativa (P 0,05) em relação ao comportamento expresso na presença da massagista em G4 e G5, entre as semanas 1 e 2. A maioria das cabras aceitou a massagem, exceto G2, com maiores demonstrações de comportamentos positivos do que negativos direcionados à massagista. Portanto, a massagem do tipo stroking promoveu interações positivas entre a massagista e as cabras, devendo ser explorada como um método alternativo aos existentes na melhora da relação entre seres humanos e animais de produção.(AU)

Terapia otológica induz imunotoxicidade em cão / Otological therapy induces imunnotoxicity in dog

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.

Mupirocin pemphigus-like drug reaction in a dog

Background: Pharmacodermia is defined as adverse reaction in skin, mucosa and appendages, which generates morphofunctional alterations in cutaneous barrier, inducing autoimmune diseases, such as pemphigus foliaceous, which is known asthe most common autoimmune skin disease in dogs. This disease involves autoantibodies against desmoglein and desmocolinmolecules, being induced by the use of certain drugs. Mupirocin (pseudomonic acid A) is a broad-spectrum antibiotic withbacteriostatic activity, being effective against Gram-positive pathogens and used to control superficial bacterial folliculitis.Based on that, the aim of this study was to report a pemphigus-like lesions after topical use of mupirocin in dog.Case: An 1-year-old, uncastrated male, Poodle dog, weighing 13.8 kg was treated in a private clinic in Fortaleza. The maincomplaint was related to pruritus in abdominal and inguinal region, in addition of legs licking. Dermatological examination revealed melanic crusts, epidermal collars and diffuse pustules in inguinal, abdominal, perianal and thoraco-lumbarregions. The therapy was based on topical use of Mupirocin in form of 0.2% aquous spray. After drug administration, theanimal presented urticaria, diffuse epidermal collars, papulo-crusted and pustular lesions, which were more evident inabdominal and inguinal region. Nasal erythema, binocular blepharitis, apathy and fever were also observed. Cytologicalexamination and bacterial culture were performed, revealing inflammatory and acantholytic cells and no bacterial growth.Biopsy procedure revealed subcorneal pustule with presence of epithelial acantholytic cells and neutrophils, compatiblewith canine pemphigus foliaceous. The topical treatment of ocular lesions with 0.1% Tacrolimus associated with systemictreatment with high dose of prednisolone (1.2 mg kg-1)...

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.(AU)

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.

Mupirocin pemphigus-like drug reaction in a dog

Background: Pharmacodermia is defined as adverse reaction in skin, mucosa and appendages, which generates morphofunctional alterations in cutaneous barrier, inducing autoimmune diseases, such as pemphigus foliaceous, which is known asthe most common autoimmune skin disease in dogs. This disease involves autoantibodies against desmoglein and desmocolinmolecules, being induced by the use of certain drugs. Mupirocin (pseudomonic acid A) is a broad-spectrum antibiotic withbacteriostatic activity, being effective against Gram-positive pathogens and used to control superficial bacterial folliculitis.Based on that, the aim of this study was to report a pemphigus-like lesions after topical use of mupirocin in dog.Case: An 1-year-old, uncastrated male, Poodle dog, weighing 13.8 kg was treated in a private clinic in Fortaleza. The maincomplaint was related to pruritus in abdominal and inguinal region, in addition of legs licking. Dermatological examination revealed melanic crusts, epidermal collars and diffuse pustules in inguinal, abdominal, perianal and thoraco-lumbarregions. The therapy was based on topical use of Mupirocin in form of 0.2% aquous spray. After drug administration, theanimal presented urticaria, diffuse epidermal collars, papulo-crusted and pustular lesions, which were more evident inabdominal and inguinal region. Nasal erythema, binocular blepharitis, apathy and fever were also observed. Cytologicalexamination and bacterial culture were performed, revealing inflammatory and acantholytic cells and no bacterial growth.Biopsy procedure revealed subcorneal pustule with presence of epithelial acantholytic cells and neutrophils, compatiblewith canine pemphigus foliaceous. The topical treatment of ocular lesions with 0.1% Tacrolimus associated with systemictreatment with high dose of prednisolone (1.2 mg kg-1)...(AU)

Alterações leucocitárias pré-vacinais induzidas por ectoparasitas em cães filhotes / Pre-vaccination leukocyte changes induced by ectoparasites in puppies

The immunization process is an important practice in the veterinary clinical routine, being dependent on the immune system and influenced by several factors, such as the presence of ectoparasites. Therefore, the objective of the present study was to evaluate the pre-vaccination leukocyte parameters in puppies with ticks. A retrospective study was carried out through the evaluation of clinical files and hematological data of 30 clinically healthy puppies divided into two groups, G1 (n=15) composed of animals without ticks and G2 (n=15) by dogs with ticks. The G2 group had significant changes in total leukocytes and neutrophils. Therefore, it was concluded that the presence of ticks induced leukocyte alterations in dogs submitted to pre-vaccine clinical evaluation.(AU)

Lesões gástricas em cães não domiciliados na cidade de Fortaleza / Gastric lesions in houseless dogs in Fortaleza city

Objetivou-se avaliar a presença de lesões gástricas em cães não domiciliados da cidade de Fortaleza. Cães, ambos os sexos, idade variada e sem raça definida foram utilizados neste protocolo. Os cães provenientes de diferentes bairros da cidade de Fortaleza foram destinados ao procedimento de eutanásia pelo canil da Unidade de Vigilância de Zoonoses (UVZ) do município de Fortaleza, Ceará, Brasil. O projeto foi aprovado pelo Comitê de Ética da Universidade Estadual do Ceará. A investigação foi conduzida entre os meses de outubro e novembro de 2004. Foram utilizados 254 cães, sendo 164 machos e 90 fêmeas eutanasiados, e, em seguida, os estômagos foram removidos, abertos ao longo da curvatura maior, lavados, enxugados e avaliados macroscopicamente. As alterações gástricas foram agrupadas de acordo com a localização anatômica. A presença de lesões gástricas foi observada em 60 animais, representando 23,62%, sendo que 14,96% eram machos e 8,66% fêmeas. As alterações macroscópicas foram localizadas no corpo (51%), antro (19%) e fundo (8%) do estômago. Não foram encontradas lesões nas regiões da cárdia e pilórica. As úlceras foram as lesões encontradas com maior frequência (15,5%) acometendo 21 cães. Foram também observadas perdas de pregas da mucosa, alterações na coloração da mucosa gástrica, petéquias, hemorragias, nódulos e lacerações. Pode-se concluir que as gastropatias são frequentes em cães não domiciliados na cidade de Fortaleza. Os resultados apresentados indicam a relevância do assunto pesquisado e a contribuição para a clínica médica veterinária e, consequentemente, para a Saúde Pública.(AU)

The aim of this study was to evaluate the presence of gastric lesions in non-domiciled in the Fortaleza city. Dogs, both sexes, varied age, no race defined were used in this protocol. The dogs from different neighborhoods of Fortaleza city were assigned to the procedure of euthanasia by the Kennel of the Unidade de Vigilância de Zoonoses (UVZ) of the city of Fortaleza, Ceará, Brazil. The project was approved by the Ethics Committee of the State University of Ceará. The study was conducted between October and November 2004. A total of 254 dogs were used, of which 164 males and 90 females were euthanized, and then the stomachs were removed, opened along the greater curvature, washed, dried and macroscopically evaluated. Gastric alterations were grouped according to the anatomical location. The presence of gastric lesions was observed in 60 animals, representing 23.62%, which 14.96% were males and 8.66% females. Macroscopic alterations were found in the body (51%), antrum (19%) and fundus (8%) of the stomach. No lesions were found in the cardia and pyloric regions. Ulcers were the most frequent lesions (15.5%), affecting 21 dogs. Loss of mucosal folds was also observed; changes in the coloration of the gastric mucosa; petechiae, haemorrhages, nodules and lacerations. It can be concluded that gastropathy is frequent in dogs not domiciled in the city of Fortaleza. The results presented indicate the relevance of the subject researched and the contribution to the veterinary medical clinic and consequently to Public Health.(AU)
