Frequência das doenças de pele não tumorais em cães no município de João Pessoa, Paraíba, Brasil (2014-2016) / [Frequency of non tumor skin diseases in dogs in the city of João Pessoa, Paraíba, Brazil (2014-2016)]

Diante da carência de estudos sobre a frequência de dermatopatias que acometem cães por região geográfica no Brasil, o presente estudo objetivou conhecer a frequência das principais doenças cutâneas que afetam cães na região metropolitana de João Pessoa, Paraíba, Brasil. Os dados foram coletados de cães que passaram por atendimento dermatológico no período de setembro de 2014 a dezembro de 2016. Além dos exames clínicos e dermatológicos os cães foram submetidos a exames complementares (citológico, raspado de pele, parasitológico, tricograma, bacteriológico, micológico, histopatológico e molecular). No período do estudo, foram atendidos 1.083 cães, em que 18,65% (202/1.083) apresentavam algum tipo de dermatopatia não tumoral. Dos 202 cães acometidos, 51,49% (104/202) eram machos e 48,51% (98/202), fêmeas. Desses 202 cães, 13 tinham dois diagnósticos, totalizando 215 dermatopatias. Dos cães afetados, 62,87% (127/202) eram de raça definida e 37,13% (75/202), sem raça definida (SRD). As lesões observadas com mais frequência caracterizaram-se por áreas alopécicas, hipotricoicas, maculosas, erosivas e ulcerativas, placoides, eritematosas, assim como comedões, colaretes, seborreia. As dermatopatias parasitárias foram as mais frequentes (35,35%; 76/215), seguidas pelas dermatopatias bacterianas (24,19%; 52/215), dermatopatias alérgicas (20,00%; 43/215), dermatopatias fúngicas (17,21%; 37/215), dermatopatias por outras causas (2,32%; 5/215) e pelas dermatopatias autoimunes (0,93%; 2/215). Os exames físicos e dermatológicos, incluindo anamnese detalhada, histórico clínico apurado, associado a exames complementares, são ferramentas importantes para o diagnóstico das dermatopatias em cães. Presume-se que a frequência de dermatopatias em cães na região de estudo possa ser maior do que a observada.(AU)

Faced with the lack of studies on the frequency of dermatopathies that affect dogs by geographical region in Brazil, the present study aimed to evaluate the frequency of dermatopathies that affect the canine species in the metropolitan region of João Pessoa, Paraíba, Brazil. Data was collected from dogs that underwent dermatological care from September 2014 to December 2016. In addition to the clinical and dermatological examinations, dogs underwent complementary exams, such as cytological, skin scraping, parasitological skin examination, trichogram, bacteriological, mycological, histopathological and/or polymerase chain reaction. During the study period, 1,083 dogs were examined, in which 18.65% (202 /1,083) had some form of non-tumoral dermatopathy. Of the 202 dogs affected, 51.49% (104/202) were males and 48.51% (98/202) females. Of these 202 dogs, thirteen had two diagnoses, totaling 215 dermatopathies. 62.87% (127/202) of the affected dogs were purebred and 37.13% (75/202) were without a defined breed (WDB). The most frequently observed lesions were alopecia, hypotric, macular, erosive and ulcerative, placoid, erythematous areas, as well as comedones, collaretes and seborrhoea. The parasitic dermatopathies were the most frequent (35.35%; 76/215), followed by bacterial dermatopathies (24,19%; 52/215), allergic dermatopathies (20,00%; 43/215), dermatomycosis (17,21%; 37/215), dermatopathies for other causes (2,32%; 5/215) and autoimmune dermatopathies (0.93%; 2/215). Clinical and dermatological examination, including a detailed anamnesis, accurate clinical history and associated complementary exams are important tools for the diagnosis of dermatopathies in dogs. Available literature present some studies with canine dermatopathies frequencies superior to that obtained in the present study; however, the number of animals examined was smaller. In this survey, it was possible to establish the primary and secondary diagnoses in 100.0% of the non-tumoral dermatopathies in dogs, results higher than in previous studies. Probably, the frequency of canine dermatopathies in this region is higher than that observed, thus requiring additional studies with greater sampling.(AU)

Male pseudohermaphroditism in equine / Pseudo-hermafroditismo masculino em um equino

Background: Intersexuality is considered an alteration in the animal development that opposes the characteristics determined by the genetic sex, resulting in an individual with characteristic features of both sexes. The objective of this work is to report a case of male pseudohermaphroditism of a Criollo breed horse referred to the Hospital de Clínicas Veterinárias (HCV) of the Universidade Federal de Pelotas, RS, Brazil. We gather information on the intersexuality diagnostics highlighting cytogenetics as an additional tool to diagnosis. Case: A Criollo breed horse was attended at the HCV with the main complaint of morphological anomaly of the external genitalia. The animal presented female external features, characterized by mammal glands and female genitalia. The horse also showed a rudimentary penis-like structure, caudally oriented shrouded by a cutaneous crease similar to a vulva and presented male behavior. The external genitalia was examined but the vaginoscope could not be inserted since the crease ended in a sac, with no openings. Rectal palpation and transrectal ultrasound could not reveal the presence of female gonads. Urethral ultrasound revealed the pelvic urethra and the openings of the male accessory glands. The equine was subjected to hormonal challenge with human chorionic gonadotropin (hCG). First sample presented a testosterone concentration of 20 ng/dL; [...](AU)

Lesões associadas à laminite subclínica e exame radiográfico digital em vacas da raça holandês no período transicional / Lesions associated with subclinical laminitis and digital radiographic exam in holstein cows in the transitional period

Subclinical laminitis has been responsible for economic losses in dairy industry; thus, its diagnostic    is very important to prevent negative responses to milk production industry. The aim of this study  was to identify lesions associated with subclinical laminitis during the transition period with presence or absence of radiographic signs linked to this disease in Holstein cows. The cows were evaluated during the transition period and categorized into two groups (with and without laminitis) according to the lesions associated with this subclinical disease. The radiological dynamic was performed in two target points during the transition period (prepartum and postpartum), with the objective of determining capsular position possible alterations and third phalanx bone degeneration (F3). There was no effect of the presence of lesions associated with subclinical laminitis regarding the position of the third phalanx to the hoof wall (p>0.05). Significant radiographic angular differences (p 0.05) between F3 and the hoof wall were observed between the lateral and medial nails of the same digit, but not within groups (p>0.05). Overall, this study did not show radiographic signs of phalangeal misalignment in the hoof of dairy cows with lesions associated with subclinical laminitis during the transition period.

A laminite subclínica é responsável por grandes prejuízos na pecuária leiteira, sendo o seu diagnóstico de grande relevância para evitar reflexos negativos na produção. Portanto, o objetivo deste trabalho foi relacionar lesões associadas à laminite subclínica no período de transição de vacas da raça Holandês com a ocorrência ou não de sinais radiográficos vinculados a essa enfermidade. As vacas foram avaliadas durante o período de transição e divididas em dois grupos (com e sem sinais de laminite subclínica) de acordo com as lesões associadas a essa enfermidade subclínica. A dinâmica radiológica foi realizada em dois momentos durante o período de transição, com o propósito de determinar possíveis alterações de posicionamento capsular e degeneração óssea da terceira falange (F3). Não foram observados efeitos da presença de lesões associadas à laminite subclínica frente ao posicionamento da terceira falange      à cápsula do casco (p>0,05). Diferenças radiográficas significativas (p 0,05) angulares entre a F3 e      a cápsula do casco foram observadas entre as unhas lateral e medial do mesmo dígito, mas não entre grupos (p>0,05). Assim, neste estudo, vacas leiteiras no período de transição com lesões associadas      à laminite subclínica não apresentaram sinais radiográficos de desalinhamento falangeano ao estojo córneo digital.
