- Abstract
Background: Melanoma is a malignant neoplasm that arises from melanocytes and malanoblasts. It is also more frequently reported in dogs than in other species. They may arise from melanocytes in the skin, on the surfaces of the mucous membranes, and eyes. The aim of this study was to describe the epidemiological aspects, risk factors and clinicopathological findings of melanoma in dogs in the backlands, northeastern Brazil. Materials, Methods & Results: A retrospective study was carried out in all biopsy samples and necropsy examinations of dogs, from January 2003 to December 2021, at the Animal Pathology Laboratory of the Federal University of Campina Grande, Patos, Paraiba, northeastern Brazil. Epidemiological data, clinical signs, and gross lesions were reviewed from the diagnostic laboratory reports. Samples of the skin, lymph nodes, central nervous system and organs of the thoracic and abdominal cavities were fixed in 10% buffered formalin, processed routinely for histopathology, embedded in paraffin wax, cut into 4 µm sections, and stained with hematoxylin and eosin (HE). Histological sections were also submitted to immunohistochemistry with the primary antibody anti-Melan A. Of the 4717 records found, 1158 (24.5%) were diagnosed with neoplasms, of which 48 (4.14%) cases were of melanoma. Of this total, 28 (58.3%) dogs were elderly, 19 (39.6%) were adults, and 1 (2.1%) was young. Mixed breed animals were the most affected (42.6%), followed by the pinscher breed (19.1%). According to the anatomical region, the most affected site was the skin (38/53=71.7%), followed by the oral cavity (12/53=22.65%) and the eyes (3/53=5.7%). Grossly, the skin lesions were characterized by exophytic and usually blackened, sometimes irregular and firm, nodules. At cut, they had a smooth, compact and blackened surface. Lesions in the oral cavity were characterized by blackened, irregular and infiltrating nodules or masses. The ocular lesions were always unilateral and were characterized by an enlarged and diffusely blackened eyeball, with areas of ulceration and subversion of tissue architecture. In 5 animals there was more than one anatomical site affected, totaling 53 lesions. In 9 (17%) cases, metastases were identified, 8 in regional lymph nodes and 1 in the lung. Histopathology showed a densely non-encapsulated, poorly delimited, expansive and infiltrative neoplasm, composed of neoplastic cells arranged in islands or nests and supported by fibrovascular stroma, containing a variable amount of brownish pigment (melanin). Immunohistochemistry showed strong immunostaining of the neoplastic cells in brown by the anti-Melan A antibody. Discussion: The diagnosis of melanoma was established based on epidemiological, clinical, anatomopathological, and immunohistochemical findings. Gender is not a predisposing factor, and although there was no statistically significant relationship, males were more affected. Senescence is a conditioning risk factor. Elderly animals were more affected (P < 0.0001) than adult ones, with OR = 4.38; and young ones (P = 0.0051), with OR = 12.65. Some breeds, especially those with marked skin pigmentation, were more affected, however the most affected ones in this survey were pinscher and poodle. Cutaneous melanoma accounted for almost 72% of cases, contesting recent studies where oral cavity melanoma was more frequent. Therefore, it is believed that the climatic conditions of the backlands sub-region, in northeastern Brazil, associated with the individual characteristics of the dogs, are involved in the development of these neoplasms, since the climate is predominantly dry, with high temperatures throughout the year, with maximums that can reach 40ºC, favoring the exposure to high incidence of ultraviolet radiatio [ABSTRACT FROM AUTHOR]

ABSTRACT: Canine atopic dermatitis (CAD) is a pruritic, chronic inflammatory disease, recurrent and genetically predisposed, which is the second most frequent allergic skin disorder, and ranks second among all the causes of pruritus in dogs worldwide. Given the absence of data on the occurrence of CAD in the northern region of Brazil, the aim of the current study was to conduct a survey to define the prevalence of canine atopic dermatitis attended at the Dermatology Department of the Mário Dias Teixeira Veterinary Hospital of the “Universidade Federal Rural da Amazônia” (HOVET-UFRA). To determine the prevalence of CAD, a retrospective survey was carried out of clinical records and results of dermatological examinations conducted at the Dermatology Department of HOVET-UFRA Belém, Pará from October 2018 to October 2019. During this period, 456 dogs were examined, of which 25.65% (117) were diagnosed with atopic dermatitis. Among the animals diagnosed, 62.4% (73) were females and 51.7% (29) were of the Shih-tzu breed. This level of atopic dermatitis is considered high. There are still no exact data on the incidence and prevalence of this dermatopathy, with described occurrence ranging from 3 to 15% of the canine population, a geographical relationship may be present. Although a sex-related predisposition has not been proven, a higher incidence of atopy in females is described, which indicated this may be the case. The most commonly diagnosed dogs in this study were the Shih-tzu breed. It is suspected that the regional popularity of some breeds, or the different genetic backgrounds in different geographical areas, may affect the predominance of CAD in some breeds. The results of the present study demonstrate the need for more research on the prevalence of canine atopic dermatitis, and better means of characterizing the population of atopic dogs in the region, so that it is possible to obtain a reliable epidemiological profile.

Abstract Leishmania infantum is a trypanosomatid that causes parasitic dermatopathy in dogs. Trypanosoma caninum is another trypanosomatid, which infects the skin of dogs, although cutaneous abnormalities are absent. This study aimed to investigate the occurrence of T. caninum infection and its associated cutaneous and histological changes and compare it with the occurrence of L. infantum infection in dogs. The study included 150 dogs, of which T. caninum infection was identified in 3 (2%) and L. infantum infection in 15 (10%) of them, with no association (p>0.05) of these infections with the breed, gender, age, or cutaneous abnormalities. The cutaneous abnormalities were based on 1 (4.8%) and 12 (57.1%) dogs infected by T. caninum and L. infantum, respectively. The dermatohistopathological abnormalities in the dogs infected with T. caninum included mild perivascular lymphohistioplasmacytic infiltrates in the clinically asymptomatic ones, while in those with dermatological abnormalities, acanthosis, epidermal orthokeratotic hyperkeratosis, melanomacrophages, and co-infection with Microsporum sp. and Trichophyton sp. were observed. InL. infantum infected, the histopathological findings included chronic granulomatous inflammatory infiltrates and structures compatible with amastigotes. Despite the low frequency of T. caninum infection, our findings suggest that this trypanosomatid, unlike L. infantum, does not cause any macroscopic skin abnormalities.

The aim of this study was to report a case of pyotraumatic dermatitis in an adult canine that was treated without the use of antimicrobials associated to laser therapy. An 8-year-old male dog with skin lesions, alopecia, and severe oily seborrhoea was referred for clinical care. In the clinical evaluation, the animal presented normal parameters for the species, however due to the lesions presented, cytopathological and parasitological skin examinations were requested, which evidenced the presence of an infectious inflammatory process, suggestive of bacteria, at the cytopathological examination, and Demodex canis in the parasitological assay. The proposed treatment consisted of baths with shampoo based on chlorhexidine with miconazole, supplements based on vitamins and minerals, antiparasitic, oral glucocorticoid and later topical, omega 3 and immunostimulant, in addition to a phototherapy session. On the last return, the animal presented the remade hair. Pyotraumatic dermatitis, despite being easy to diagnose, requires full attention regarding the individualized response of each animal to the condition. In this case, the constant monitoring performed by the veterinarian, provided the establishment of the most appropriate therapeutic approach to solve the problem and restore the animal's health without the use of antimicrobials, and with the additional laser therapy.

Trichophyton rubrum is rarely isolated from dogs with dermatophytosis. It is an anthropophilic dermatophyte commonly causing infections in humans. A 4-year-old female Shih Tzu dog was brought to the veterinary clinic with a history of circular, crusted and non-pruritic alopecia lesions located on the head. Routine blood tests, skin scrapes and bacteriological culture revealed no abnormalities. However, Trichophyton rubrum was isolated from the fungus culture. The intradomicilar condition of the dog allows contact with its frequent hosts, the man. The fungicidal treatment was implemented with shampoo (ketoconazole base 2% + chlorhexidine 2%) and oral Itraconazole at a dose of 10 mg / kg once a day, for 28 days. The lesions healed completely and the hair grew back within a month. No recurrence occurred during the 4-month follow-up. T. rubrum should be included in the differential diagnosis of crusted skin lesions in dogs. [ABSTRACT FROM AUTHOR]

Dermatopathies and otopathies are recurrent cases in veterinary clinic caused by different microorganisms. The aim of the present study is to analyze reports of cytological and parasitological skin and ear examinations performed at the Clinical Laboratory of the Veterinary Teaching Clinic of Federal University of Juiz de Fora in order to determine the prevalence of bacteria, fungi and mites in the collected samples. Reports of tests carried out from January 2018 to December 2019 were analyzed. Dog otopathies comprised 42 (50%) cases caused by Malassezia sp., 11 (13.1%) cases caused by bacteria and 29 (34.5%) cases caused by mixed infections; whereas cats otopathies encompassed 7 (28%) infections caused by Malassezia sp., 3 (12%) infections caused by bacteria, 6 (24%) mixed infections and 3 (12%) infections caused by mite species Otodectes cynotis. Dog dermatopathies comprised 1 (2.6%) case caused by Malassezia sp., 17 (43.6%) cases caused by bacteria, 7 (17.9%) mixed infections and 3 (7.7%) infections caused by mite species Demodex canis; whereas cat dermatopathies comprised 2 (15.4%) changes caused by bacteria, 3 (23.1%) mixed infections, 2 (15.4%) infections caused by Sporothrix sp., 1 (7.6%) caused by dermatophyte and 3 (23.1%) by yeast. Results have shown that Malassezia sp. was the most prevalent etiological agent in ear diseases diagnosed in both dogs and cats. On the other hand, bacteria were the most prevalent agents in dog skin disorders, whereas mixed infections and fungal agents recorded similar prevalence in cats. [ABSTRACT FROM AUTHOR]

Although not obligatory pathogens, Microsporum gypseum, M. canis, and Trichophyton spp. are related to infections in animals, usually associated with circular lesions on the skin. Dermatophytosis by geophilic dermatophytes occurs to a lesser extent, having M. gypseum as the main etiologic agent involved. Among the factors linked to the ability of dermatophytes to infect animals, we highlight enzymes such as DNase, gelatinase, lipase, keratinase, elastase, and collagenase, which were evaluated in the present study. The behavior of domestic animals to be in close contact with the ground, in backyards, public roads, and parks justify the study of geophilic dermatophytes virulence factors and the changes on the enzymatic production between clinical and environmental isolates, which may contribute to control strategies and prevention of dermatophytosis. The main goal of this study was to evaluate the production capacity of enzymes related to the pathogenicity of dermatophytes (DNase, lipase, gelatinase, keratinase, elastase, and collagenase), among environmental and clinical isolates. The environmental strains were obtained by the technique described by Vanbreuseghem (1952), which uses pre-sterilized equines hair mixed with the moist soil, using soil samples from different Brazilian locations. The clinical specimens were obtained from animal hairs and crusts sent to the Veterinary Microbiological Diagnostic Service / UFRRJ and isolated in Mycosel? medium. The enzymatic evaluation of the dermatophytes was performed by spectrophotometry absorbance (collagenase, elastase, and keratinase), enzymatic degradation in Petri dishes (DNase and lipase) and liquefaction in tubes (gelatinase). In a total of 30 clinical isolates, M. canis (11), M. gypseum (7), M. nanum (2), T. mentagrophytes (4) and Trichophyton sp. (6), were identified. Among the 30 environmental isolates are M. gypseum (25), M. nanum (1) and Trichophyton sp. (4). There was no statistically significant difference in the production of keratinase, elastase, lipase, and gelatinase between the clinical and environmental groups, with the synthesis of all the enzymes for most evaluated isolates. There was a statistically significant difference between the groups in the production of collagenase and DNase, with emphasis on the absence of DNase production by most of the environmental isolates. Thus, dermatophytes from clinical and soil samples are able to produce keratinase, elastase, collagenase, DNase, lipase and gelatinase, enzymes related to different stages of the dermatophytic infection in animals and humans. Os dermat?fitos constituem grupo de fungos que requerem queratina para crescimento, colonizando a pele e anexos de animais e pessoas. Embora n?o sejam pat?genos obrigat?rios, Microsporum gypseum, M. canis e Trichophyton spp. relacionam-se a infec??es em animais, causando classicamente les?es circulares na pele. Embora as dermatofitoses por dermat?fitos geof?licos ocorram em menor grau, M. gypseum ? a principal esp?cie envolvida e estes quadros devem ser considerados. Dentre os fatores que fazem com que os dermat?fitos, tenham capacidade de infec??o para animais, destacam-se enzimas como DNase, gelatinase, lipase, queratinase, elastase e colagenase, que foram avaliadas neste trabalho. O h?bito dos animais dom?sticos permanecerem em contato ?ntimo com a terra, em quintais, vias p?blicas e parques, justifica o estudo de sua patogenicidade e a diferencia??o do perfil enzim?tico de isolados cl?nicos e ambientais de dermat?fitos, o que pode colaborar para estrat?gias de controle e preven??o da dermatofitose. Nossa pesquisa teve como objetivos o isolamento cl?nico e ambiental de fungos dermat?fitos, avaliando a produ??o de DNase, lipase, gelatinase, queratinase, elastase e colagenase, enzimas relacionadas ? virul?ncia dos mesmos e a compara??o da capacidade de produ??o dessas enzimas relacionadas ? patogenicidade entre as cepas cl?nicas e ambientais. As cepas ambientais foram obtidas atrav?s da t?cnica descrita por Vanbreuseghem (1952), que emprega pelos est?reis de equinos misturados ao solo umedecido, sendo utilizadas amostras de solo oriundas de diferentes locais do Brasil. As amostras cl?nicas foram oriundas de pelos e crostas de animais enviadas ao Servi?o de Diagn?stico Microbiol?gico Veterin?rio/UFRRJ e semeadas em meio Mycosel?. A avalia??o enzim?tica dos dermat?fitos foi feita por leituras de absorb?ncia em espectrofot?metro (colagenase, elastase e queratinase), forma??o de halo de degrada??o em placas (DNase e lipase) e liquefa??o em tubos (gelatinase). Dentre os 30 isolados cl?nicos est?o M. canis (11), M. gypseum (7), M. nanum (2), T. mentagrophytes (4) e Trichophyton sp. (6). e dentre os 30 isolados ambientais est?o M. gypseum (25), M. nanum (1) e Trichophyton sp. (4). N?o houve diferen?a significativa estatisticamente na produ??o de queratinase, elastase, lipase e gelatinase entre os grupos de isolados cl?nicos e ambientais, sendo a maior parte dos fungos produtora de todas estas enzimas. Houve diferen?a significativa estatisticamente entre os grupos na produ??o de colagenase e DNase, com destaque para a aus?ncia de produ??o de DNase pela maioria dos isolados ambientais. Assim, conclui-se que os dermat?fitos oriundos de amostras cl?nicas e do solo s?o capazes de produzir queratinase, elastase, colagenase, DNase, lipase e gelatinase, enzimas relacionas a diferentes etapas do processo da infec??o dermatof?tica em animais e pessoas.

It has been reported in humans, dogs, cats and pigs, but, in horses, it has recently been reported in the USA. In Brazil, there were no references of the disease in horses. Due to the rarity of the disease and variety of differential diagnoses, the aim of this study was to register the first occurrence of the disease in equine in Brazil, and to describe the clinic-pathological and histopathological aspects. The horse was treated at the Veterinary Medicine Hospital of UFBA, presenting chronic skin lesions. On physical examination, there were multiple erythematous, ulcerated, crusty and itchy lesions at head, medial thigh and ventral thoracic region. Therapeutic attempts based on topical antiseptics, antibiotics and antifungals were ineffective. Parasitic, fungal and bacterial diseases have been ruled out by additional tests. Due to the worsening of clinical symptoms, the owner opted for euthanasia. At necropsy, there were macular, erosive, ulcerative lesion and intense vesicular-pustular in the muco-cutaneous junctions (lips, nostrils and anus) and coronary band. The oral mucosa was found to be hyperemic, eroded and ulcerated, with rare intact vesicles / blisters, especially the gums located close to the upper teeth and lower incisors, the inner surface of the lips and cheeks and hard palate and oral cavity floor. Throughout the dorsal surface of the tongue, there were large ulcers, usually, coalescing. Histopathology of the skin and oral mucosa revealed several sub-epidermal blistering. The diagnosis of bullous pemphigoid was based on clinical and epidemiological data, the macroscopic findings and confirmed by histopathology., O penfigóide bolhoso é uma rara e grave dermatose autoimune causada pela produção de autoanticorpos. Tem sido descrito no homem, cães, gatos e suínos, sendo apenas recentemente relatado em equinos nos Estados Unidos. No Brasil, não foram encontradas referências da doença em equinos. Devido à raridade da enfermidade e variedade de diagnósticos diferenciais, objetivou-se com este trabalho registrar pela primeira vez, a ocorrência da doença em um equino no Brasil, bem como descrever os achados clínicos e anatomohistopatológicos. O equino foi atendido no Hospital de Medicina Veterinária da UFBA, com histórico de lesões cutâneas crônicas. Ao exame físico, verificaram-se múltiplas lesões eritematosas, ulceradas, crostosas e pruriginosas na cabeça, face medial da coxa e região torácica ventral. Tentativas terapêuticas a base de antissépticos tópicos, antibióticos e antifúngicos foram ineficazes. Doenças parasitárias, fúngicas e bacterianas foram descartadas por exames complementares. Devido ao agravamento do quadro clínico o proprietário optou pela eutanásia in extremis. À necropsia, observaram-se lesões maculares, erosivas, ulcerativas e vesículo-pustulares intensas nas junções mucocutâneas (lábios, narinas e ânus) e rodete coronário. A mucosa oral encontrava-se hiperêmica, erodida e ulcerada, com raras vesículas ou bolhas intactas, sobretudo, na gengiva, mucosa dos lábios, bochechas, palato duro e assoalho cavidade bucal. Por toda a superfície dorsal da língua verificaram-se grandes úlceras, em geral, coalescentes. A avaliação histopatológica da pele e mucosa oral revelou diversas fendas subepidérmicas. O diagnóstico de penfigóide bolhoso foi estabelecido com base nos dados clínico-epidemiológicos, nos achados macroscópicos e confirmado pela histopatologia.

Due to the rarity of the disease and variety of differential diagnoses, the aim of this study was to register the first occurrence of the disease in equine in Brazil, and to describe the clinic-pathological and histopathological aspects. The horse was treated at the Veterinary Medicine Hospital of UFBA, presenting chronic skin lesions. On physical examination, there were multiple erythematous, ulcerated, crusty and itchy lesions at head, medial thigh and ventral thoracic region. Therapeutic attempts based on topical antiseptics, antibiotics and antifungals were ineffective. Parasitic, fungal and bacterial diseases have been ruled out by additional tests. Due to the worsening of clinical symptoms, the owner opted for euthanasia. At necropsy, there were macular, erosive, ulcerative lesion and intense vesicular-pustular in the muco-cutaneous junctions (lips, nostrils and anus) and coronary band. The oral mucosa was found to be hyperemic, eroded and ulcerated, with rare intact vesicles / blisters, especially the gums located close to the upper teeth and lower incisors, the inner surface of the lips and cheeks and hard palate and oral cavity floor. Throughout the dorsal surface of the tongue, there were large ulcers, usually, coalescing. Histopathology of the skin and oral mucosa revealed several sub-epidermal blistering. The diagnosis of bullous pemphigoid was based on clinical and epidemiological data, the macroscopic findings and confirmed by histopathology. O penfigóide bolhoso é uma rara e grave dermatose autoimune causada pela produção de autoanticorpos. Tem sido descrito no homem, cães, gatos e suínos, sendo apenas recentemente relatado em equinos nos Estados Unidos. No Brasil, não foram encontradas referências da doença em equinos. Devido à raridade da enfermidade e variedade de diagnósticos diferenciais, objetivou-se com este trabalho registrar pela primeira vez, a ocorrência da doença em um equino no Brasil, bem como descrever os achados clínicos e anatomohistopatológicos. O equino foi atendido no Hospital de Medicina Veterinária da UFBA, com histórico de lesões cutâneas crônicas. Ao exame físico, verificaram-se múltiplas lesões eritematosas, ulceradas, crostosas e pruriginosas na cabeça, face medial da coxa e região torácica ventral. Tentativas terapêuticas a base de antissépticos tópicos, antibióticos e antifúngicos foram ineficazes. Doenças parasitárias, fúngicas e bacterianas foram descartadas por exames complementares. Devido ao agravamento do quadro clínico o proprietário optou pela eutanásia in extremis. À necropsia, observaram-se lesões maculares, erosivas, ulcerativas e vesículo-pustulares intensas nas junções mucocutâneas (lábios, narinas e ânus) e rodete coronário. A mucosa oral encontrava-se hiperêmica, erodida e ulcerada, com raras vesículas ou bolhas intactas, sobretudo, na gengiva, mucosa dos lábios, bochechas, palato duro e assoalho cavidade bucal. Por toda a superfície dorsal da língua verificaram-se grandes úlceras, em geral, coalescentes. A avaliação histopatológica da pele e mucosa oral revelou diversas fendas subepidérmicas. O diagnóstico de penfigóide bolhoso foi estabelecido com base nos dados clínico-epidemiológicos, nos achados macroscópicos e confirmado pela histopatologia.

Made available in DSpace on 2021-06-25T10:10:29Z (GMT). No. of bitstreams: 0 Previous issue date: 2017-01-01 Background: Dermatosparaxis is an autosomal recessive genetic disease that affects the connective tissue of animals. Collagen proteins form fibrillar structures that provide strength and structure to the extracellular matrix of tissues and organs in the body. Therefore, changes in collagen synthesis result in hyperextensibility and skin fragility. Similar to dermatosparaxis in animals, some cases of Ehlers-Danlos syndrome type VIIC have been reported in humans. The objective of this study was to describe the clinical, anatomopathological, and molecular findings of a case of dermatosparaxis in a sheep bred by crossing the Santa Inês and White Dorper breeds. Case: A case of dermatosparaxis was reported in a 20-day-old female sheep, a cross between the Santa Inês and White Dorper breeds. The sheep exhibited hyperextensibility of the skin with minimal tension and increased joint volume shortly after birth. Because of clinical worsening and the poor prognosis of the disease, the owners opted for euthanasia. The necropsy revealed large ulcerated areas in several parts of the body, including the cervical, sternal, scapular, and thoracic regions, and the inner and outer thighs. The skin was extremely easy to be removed during the necropsy and the use of a scalpel was not necessary. Extensive areas of hemorrhage were observed in the subcutaneous tissue and small intestine. The histopathological findings of the skin lesions evidenced the presence of dermatosparaxis, particularly regarding the disorganization of collagen fibers. The tests involving Masson’s trichrome staining, picrosirius red staining, and Gomori’s trichrome staining under polarized light evidence of collagen fiber dysplasia. Discussion: The diagnosis of dermatosparaxis in this study was based on clinical, anatomopathological, and molecular analysis. Molecular diagnosis was confirmed by identification of SNP c.421G>T on the ADAMTS2 gene in both the mother and the sheep under study. In humans, in addition to hyperextensibility and skin fragility, other rare clinical signs include ligamentous laxity, bone abnormalities, vascular abnormalities, uterine rupture, ocular abnormalities, and extensive areas of hemorrhage in the intestine. In this case, the humeral-radial-ulnar joints of both thoracic limbs were substantially enlarged and, when sectioned, a moderate amount of dark yellow fluid was released. Dermatosparaxis is well documented in the White Dorper sheep breed. In the present study, the genetic test revealed that the mother (Santa Inês breed) was heterozygous and phenotypically normal. All the rams in the animal herd (White Dorper breed) were phenotypically normal. Extensive hemorrhage in organs of the abdominal cavity and the high likelihood of skin rupture have been reported in other species that are affected by the disease. The histopathological findings of cutaneous lesions in this sheep agree with the descriptions in the literature on the disorganization of collagen fibers. The tests involving Masson’s trichrome staining, Gomori’s trichrome, and picrosirius red staining under polarized light were crucial for providing evidence of collagen fiber dysplasia. Even when phenotypically normal, the heterozygous sheep in the herd can produce recessive homozygous animals, which may be clinically affected, mainly, if there is a history of uncontrolled crossing in the herd.

Dentre as especialidades veterinárias, a dermatologia, juntamente com oncologia foram as que se destacaram a partir de 1980. Cerca de 30% dos atendimentos clínicos de carnívoros domésticos são associados com alterações dermatológicas. A maior parte dos dados disponíveis inclui estudos de outros países o que pode não refletir a realidade brasileira. O objetivo deste estudo foi apresentar a prevalência das principais dermatologias neoplásicas e não neoplásicas registradas em gatos, através de diagnósticos histopatológicos de biópsias da pele, realizados no setor de Patologia Veterinária da Universidade Federal do Rio Grande do Sul (SPV-UFRGS). Um estudo retrospectivo incluiu os resultados de biópsias de pele em gatos registrados entre 1990 e 2012, nos arquivos de diagnósticos histopatológicos do SPV-UFRGS, Porto Alegre, RS, Brasil. De um total de 443 biópsias cutâneas em gatos, 308 casos foram lesões de origem neoplásica que ocorreram em maior prevalência (69%) e afetaram, mais frequentemente, gatos idosos, independente do sexo. Nessa categoria, destacaram-se carcinoma epidermoide 32,14% (99/308), fibrossarcoma 18,83% (58/308), tricoblastoma 12,66% (39/308) e mastocitoma 7,47% (23/308). Entre as lesões de causas não neoplásicas, foram analisadas as de causas micóticas 22,22% (30/135), das quais, a esporotricose apresentou maior ocorrência, com maior prevalência em machos. As lesões de causas alérgicas ocuparam a segunda posição 18,52% (25/135) em prevalência, na categoria não neoplásica. As três dermatopatias mais frequentes foram neoplásicas, micóticas e alérgicas. As neoplasias afetaram mais frequentemente gatos idosos, independentemente do sexo. O carcinoma epidermoide é a dermatopatia neoplásica de maior ocorrência, em gatos sem raça definida, sem predisposição sexual. A esporotricose é a dermatomicose mais frequente e afetou principalmente gatos machos. A escassez de dados registrados nas fichas de solicitação de biópsia reduziu conclusões adicionais. Partindo-se do princípio de que a dermatite solar pode evoluir para o carcinoma epidermoide, e considerando-se o expressivo número de diagnósticos desta alteração entre todas as amostras cutâneas 22,35% (99/443), pode-se reforçar a importância deste estudo ao dermatologista de um país tropical, dando subsídios para a indicação da prevenção à exposição solar, visando prevenir a ocorrência da doença, aumentando o bem-estar dos gatos. Both dermatology and oncology are areas that showed high development since the 1980s. It is estimated that approximately 30% of the clinical services for domestic carnivores have been associated with dermatological alterations. Most of the available data include studies developed outside the country and may not reflect the local situation. This study aimed to presents the prevalence of the main dermatological alterations affecting domestic cats and that were diagnosed by histopathological analysis in the Setor de Patologia Veterinária of Universidade Federal do Rio Grande do Sul (SPV-UFRGS).A retrospective study included the findings observed in feline skin biopsies recorded between 1990 and 2012 in the histopathological files from the SPV-UFRGS. In a total of 443 biopsies, 308 cases showed neoplastic origin which corresponded to most lesions (69%) and affected mostly aged cats, regardless of sex. This category included epidermoid carcinoma 32,14% (99/308), fibrosarcoma 18,83% (58/308), trichoblastoma 12,66% (39/308) and mastocytoma 7,47% (23/308). Epidermoid carcinoma was the top neoplastic dermatopathy and affected mostly undefined breed cats without sexual predisposition. Among the non-neoplastic cases, the mycoses 22,22% (30/135) and the allergic lesions 18,52% (25/135) were the most prevalent. Sporotrichosis was the predominant mycotic alteration and affected especially male cats. Therefore, the three most prevalent categories of dermatopathies affecting cats were neoplasia, mycosis and allergy. Thelack of data recorded in the clinical sheets for biopsy request minimized additional conclusions. Results showed here are highlighted upon consideration that solar dermatitis may evolve to epidermoid carcinoma, which has occurred in a high prevalence in this tropical country, where the prevention to the exposition of these animals to the solar radiation assumes a great role for animal care.

O plasma rico em plaquetas (PRP) é um produto derivado da centrifugação do sangue total, sendo rico em fatores bioativos, como os de crescimento. Apesar da ampla utilização em processos cicatriciais, há controvérsia sobre a eficácia da terapia na cicatrização cutânea. O objetivo desse estudo foi quantificar e comparar a concentração dos fatores TGF-β1 e PDGF-BB no PRP, plasma sanguíneo e pele, durante diferentes fases do processo de cicatrização da pele tratada ou não com PRP. Foram utilizados sete equinos machos castrados, mestiços, hígidos, com idade entre 16 e 17 (16,14±0,63) anos. Três lesões em formato quadrangular (6,25cm2) foram produzidas cirurgicamente nas regiões glúteas direita e esquerda de todos os animais. Doze horas após indução das feridas, 0,5mL do PRP foi administrado em cada uma das quatro extremidades das feridas de uma das regiões glúteas (Grupo tratado = GT), escolhida aleatoriamente. A região contralateral foi utilizada como controle (GC). As feridas foram submetidas à limpeza diária com água Milli Q, e amostras foram obtidas mediante biópsias realizadas com Punch de 6mm. Foram obtidas seis biópsias de pele, sendo a primeira realizada logo após a produção da ferida (T0), e as demais com 1 (T1) 2 (T2) 7 (T3) e 14 (T4) dias após a indução da lesão. A sexta biópsia (T5) foi obtida após completo fechamento da pele, que ocorreu aproximadamente aos 37 dias (36,85±7,45, GC; 38,85±6,46, GT). Também foram obtidas amostras de sangue com EDTA em todos os tempos mencionados. A quantificação dos fatores de crescimento TGF-β1 e PDGF-BB na pele, PRP e plasma sanguíneo foi realizada pela técnica ELISA. Os dados foram analisados estatisticamente pelo teste t, correlação de Pearson e regressão, utilizando nível de significância de 5%. Não houve diferença entre os grupos, nos valores dos dois fatores de crescimento mensurados na pele, nos diferentes tempos. Também não houve correlação entre a quantidade dos fatores de crescimento presentes na pele e no plasma. Por outro lado, correlação positiva foi observada entre PRP e pele no grupo tratado, para os fatores de crescimento TGF-β1 (r=0,31) e PDGF-BB (r=0,38), bem como entre ambos os fatores de crescimento presentes no PRP (r=0,81). Considerando as concentrações dos fatores de crescimento no T0, os maiores valores cutâneos (p

Visceral leishmaniasis is an infectious disease of chronic, emerging and zoonotic nature that presents various degrees of severity. In Brazil, this illness is caused by Leishmania infantum (Leishmania chagasi), which is transmitted by the bite of the sand fly Lutzomyia longipalpis, and dogs are its main reservoir. Given the increasing spread of this disease across Brazil, the aim of this study was to report on six cases of canine visceral leishmaniasis, diagnosed in June 2013, in the city of Pedregulho, State of São Paulo, considered to be a non-endemic area and free of phlebotomine sand flies. The diagnosis was based on clinical signs of the patients and additional tests (serological and parasitological). It was concluded that the diagnosis of leishmaniasis is complex because the clinical signs are similar to other systemic diseases, thus justifying the importance of parasitological test of bone marrow, considered "gold standard", in the confirmation of the disease. In addition, the area was not, until now, considered risk place, despite notification.

A number of 266 (6.5%) animals were diagnosed with hypothyroidism. All 100% of the subjects had skin or coat disorders; moreover, 35.7% also had non cutaneous clinical signs of hypothyroidism. The most common dermatopathies were hair coat disorders (65.8%) and keratinization disorders (46.6%). The more repeated non cutaneous clinical signs in the study were metabolic disorders (19.6%) and reproductive (19.2%). The diagnosis of the disease was confirmed dosing the thyroid hormone and TSH (18%), biopsy and histopathology of the skin (35.3%) also by the association of both procedures (46.7%). Within these last group of animals , the histopathology was considered as the most efficient diagnosis method for hypothyroidism (97.6% / 98.2%) as for the Hormone tests the efficiency of this diagnosis was less expressive: T4 Free (72.7% / 75.8%) e T4 Total (77.8% / 73.9%). A percentage of 68,5% of the animals with hypothyroidism , had 1 or 2 secondary diseases or associated to the endocrinopathy, from which immune mediated disorders (45,9%) were accentuated . 157 of the diagnosed patients were submitted to treatment, with positive results in 93.6% of the cases. The disease was most found in females (57,9%). Dogs from 1 to 8 years old (81,6%) represented the age range of the affected animals. There were 43 breeds of dogs involved in the study, from which Chow Chow, Shar pei and English Cocker Spaniel were considered to have predisposition for the disease. Este estudo foi realizado no setor de Dermatologia da Cl?nica Veterin?ria Anim?lia Rio de Janeiro RJ, no per?odo de agosto de 1998 a dezembro de 2005. Do total de c?es atendidos na cl?nica (4107), 19,7% foram encaminhados ao setor, e em 266 destes (6,5%) foi diagnosticado hipotireoidismo. Em todos os c?es foram observadas altera??es na pele, enquanto que, 35,7% tinham tamb?m sintomas cl?nicos n?o cut?neos do hipotireoidismo. As dermatopatias mais comuns foram os dist?rbios de pelagem (65,8%) e os dist?rbios de queratiniza??o (46,6%). Dos sinais cl?nico-gerais n?o cut?neos, destacaram-se dist?rbios metab?licos (19,6%) e reprodutivos (19,2%). O diagn?stico de hipotireoidismo foi realizado atrav?s de dosagens dos horm?nios tireoidianos e TSH (18%), pela bi?psia e histopatologia de pele (35,3%) e pela associa??o entre estes m?todos (46,7%). Neste ?ltimo grupo de animais, a histopatologia foi considerada como o m?todo de diagn?stico mais eficaz para o hipotireoidismo (97,6% / 98,2%). Com rela??o ?s dosagens hormonais, a efic?cia para este diagn?stico foi menos expressiva: T4 Livre (72,7% / 75,8%) e T4 Total (77,8% / 73,9%). Dos animais com hipotireoidismo, 68,5% tinham 1 ou 2 doen?as secund?rias ou associadas ? endocrinopatia, das quais destacam-se os processos imunomediados (45,9%). Dos animais hipotireoideos, 157 foram submetidos ao tratamento, com resposta positiva em 93,6%. As f?meas (57,9%) foram mais acometidas. Animais com idades entre 1 a 8 anos (81,6%) representaram a faixa et?ria mais freq?entemente afetadas. Dentre as 43 ra?as de c?es acometidas, foram consideradas predispostas Chow Chow, Shar pei e Cocker Spaniel Ingl?s.
