RESUMO

The objective of this study was to evaluate and compare the sonographic characteristics of the digital flexor tendons and ligaments of the palmar/plantar of the metacarpal and metatarsal regions in gaited horses, as well as to establish normal reference ultrasound values for Mangalarga Marchador (MM) and Campeiro breeds. Transverse sonographic images were obtained of 50 adult and healthy horses from the MM (n = 25) and Campeiro (n = 25) breeds. The images were taken in six metacarpal/metatarsal zones, and the following measurements were taken: transverse area, circumference, dorsopalmar/plantar length, lateromedial length, and mean echogenicity. Differences were observed between breeds in the fore- and hindlimbs, and, even when not significant, the Campeiro breed tended to have higher values for most variables and structures. Variations between zones and between structures in the same zone followed a similar trend in both breeds for all variables. In addition, the dimensions and variations between zones and structures were different between the fore- and hindlimbs, highlighting the need for specific values for the digital flexor tendons and ligaments of the metatarsal plantar region. In conclusion, the digital flexor tendons, suspensory ligaments, and accessory ligaments of the digital deep flexor tendon are influenced by the breed factor in gaited horses, and they are different between the fore- and hindlimbs.

RESUMO

This study aimed to measure the concentrations of minerals in different regions and pigmentation of horses hooves, mules and donkeys. A total of 20 Crioulo horses, 20 mules and 20 Pega donkeys were used. They formed two groups: pigmented (dark) or non-pigmented (bright) hooves. All animals were unshod and with adequate foot conformation. Females were nonpregnant and without foal and no animals were in training. Samples were collected from the hooves of all limbs in the regions of wall, sole and frog. The concentrations of calcium, magnesium, copper, iron and zinc were determined by atomic absorption spectrophotometry; sodium and potassium concentrations were determined by atomic emission spectrophotometry. Among the groups it was observed that the wall, sole and frog of donkeys hooves presented higher concentrations of sodium and calcium and with the exception of the frog that also obtained higher levels of copper in this species. Mules had lower concentrations of zinc in the wall and the horses had higher concentrations of potassium and zinc in the sole and higher magnesium in the frog and wall. There was no difference (P>0.05) in concentrations regarding the pigmentation of the hooves. The different regions of the hooves in each group presented similar concentrations of minerals and it was regardless of the pigmentation. The mineral concentrations may be related to desirable functional properties of the donkeys hooves. Pigmented and non-pigmented hooves have similar concentrations of minerals.(AU)

O objetivo desse trabalho foi mensurar os teores de minerais nas diferentes regiões e pigmentações dos cascos de equinos, muares e asininos. Utilizaram-se 20 equinos da raça Crioula, 20 muares e 20 asininos da raça Pêga. Formaram-se dois grupos conforme os cascos pigmentados (escuros) e não pigmentados (claros). Todos os animais estavam desferrados e com adequada conformação podal e as fêmeas estavam não gestantes e sem potro ao pé e nenhum animal estava em treinamento. Amostras foram coletadas dos cascos de todos os membros nas regiões de parede, sola e ranilha. As concentrações de cálcio, magnésio, cobre, ferro e zinco foram determinadas por espectrofotometria de absorção atômica e as concentrações de sódio e potássio foram determinadas por espectrofotometria de emissão atômica. Entre os grupos observou-se que a parede, sola e ranilha nos asininos apresentaram maiores valores de sódio e cálcio e, exceto para a ranilha, também obteve-se maiores teores de cobre nesta espécie. Os muares apresentaram menores teores de zinco na parede e, os equinos, maiores teores de potássio e zinco na sola e ranilha e de magnésio na ranilha e parede. Não houve diferença (P>0,05) nos teores dos minerais quanto à pigmentação dos cascos. As diferentes regiões dos cascos em cada grupo apresentaram teores similares de minerais e este independeu da pigmentação. As variações dos teores de minerais entre os grupos podem estar relacionados a propriedades funcionais desejáveis dos cascos dos asininos. Cascos pigmentados e não pigmentados apresentam teores similares dos minerais.(AU)

RESUMO

A cross-sectional study was conducted in 274 cats for determination of FeLV antigenemia and FIV seropositivity and factors associated with those infections in cats presented at the Veterinary Hospital of the Santa Catarina State University - UDESC (Brazil). Apparent prevalence for sick cats at the hospital population was 28.41% (95%CI 21.88-34.94%) for FeLV, 7.65% (95%CI 3.71-11.50%) for FIV and 2.18% (95%CI 0.56-5.47%) for both viruses. For healthy cats, the apparent prevalence was 9.89% (95%CI 3.75-16.02%) for FeLV, 2.20% (95%CI 0.34-7.75%) for FIV by immunoassay (ELISA). Average age for FeLV- and FIV-positive individuals was 38.32 and 64.25 months, respectively. Behavior such as aggressiveness and sex (male) were both associated with increased odds of result positivity test for FeLV and FIV; older animals were also associated with FIV test results. A very small proportion of the animals were vaccinated against FeLV and none against FIV. Most of the animals were adopted from shelters or rescued from streets, living with multiple cats that had access to outdoors. The high prevalence of FeLV suggests a need for better control strategies against this disease.

RESUMO

The vertebral heart score or size (VHS) measurement is routinely used to provide a more objective measurement of cardiomegaly in dogs. However, breed or body conformation can influence the VHS. To assess the specific VHS for the Australian Cattle Dog, left-to-right lateral, right-to-left lateral, dorsoventral and ventrodorsal thoracic radiographs from 20 individuals free from cardiac and pulmonary disease were obtained. The mean VHS was significantly higher in Australian Cattle Dog (10.5 ± 0.4 vertebrae), when compared with the average VHS for 100 normal dogs of different breeds that had been initially published (9.7 ± 0.5 vertebrae). This emphasizes the importance of breed-specific VHS ranges. In our study group of normal Australian Cattle Dogs, the mean VHS was 10.5 ± 0.5 vertebrae (mean ±SD) on right lateral and 10.3 ± 0.5 vertebrae on left lateral radiographs. The VHS on right lateral views was significantly larger than on left lateral views. The VHS was 10.5 ± 0.6 vertebrae on dorsoventral and 11.1 ± 0.6 vertebrae on ventrodorsal radiographs. The VHS on ventrodorsal views was significantly larger than on dorsoventral views.

RESUMO

Background: The occurrence of congenital defects in the sheep is estimated to be between 0.2% and 2%. For congenital anatomical alterations, diagnostic imaging allows objective understanding and evaluation, and is a great aid in the formulation of clinical decisions. Most of these anomalies are diagnosed by radiography; but computed tomography (CT) can provide important additional information. In the current literature there are no descriptions of the use of radiography and CT for a more detailed evaluation of the anatomical structures in cases of congenital cervical malformations in lambs. The objective of this study is to report the clinical, radiographic and tomographic findings in two cases of congenital cervical vertebral malformation in lambs.Cases: Two lambs with cervical morphological alterations since birth were attended. A 4-month-old mixed-breed lamb, weighing 11 kg, with lateroventrocaudal deviation of the neck was observed to the right side, not yielding to the attempt of repositioning. The owner reported that these changes were identified since birth, leading to difficulties in suckling colostrum, necessitating artificial feeding. With the growth of the animal, worsening of the cervical deviation resulted in the impossibility of grazing. The radiographs of the cervical spine identified marked scoliosis, and the axis presented small dimensions and morphological changes with a slight loss of atlantoaxial articular relationship. Spondylopathies were detected along the cervical spine. Other lamb of the Lacaune breed, weighing 4.2 kg, was presented shortly after birth with changes in the shape and posture of the neck, difficult locomotion and in sternal decubitus. The owner reported that the lamb came from a twin eutocic birth, with the other lamb being apparently normal. The animal was unable to ingest the colostrum, in which the sheep was milked and colostrum was offered through a bottle.[...](AU)

RESUMO

Background: The eosinophilic bronchopneumopathy (EBP) is characterized by pulmonary infiltration with eosinophils. The etiology of canine EBP remains unclear, although hypersensitivity to aeroallergens is suspected. Dogs affected are usually young. The persistent cough is the most common clinical sign, often associated with respiratory difficulty and exercise intolerance. The diagnosis is based on signalment, radiographic and bronchoscopic findings, and the tissue eosiphilic infiltration demonstrated by cytology of bronchoalveolar lavage (BAL). No reports were found in Brazil. The aim of this paper is report four cases of canine BPE, with emphasis on clinical aspects, diagnosis and therapy.Cases: Case 1. A 18-month-old female dog with 12 kg of body weight was presented for consultation with a 60-day history of cough, inappetence and weariness. It presented cough and tachypnea. The complementary exams demonstrated peripheral eosinophilia, bronchointersticial pulmonary pattern on radiography, moderate amount of mucus on bronchoscopy and tissue eosinophilis infiltration on the BAL. The treatment was based on steroids, with improvement of clinical signs. Case 2. A 24-month-old female dog with 16 kg of body weight was presented for consultation with one-year history of cough, inappetence and lethargy. It presented only cough, and in complementary exams showed transitory peripheral eosinophilia, bronchointersticial pattern on radiography and predominantly eosinophilic inflammation on citology of BAL. The therapy was based on steroids, with improvement followed by worsening of signs, with need of readjustment of doses. Case 3. A 8-year-old male dog with 6.2 kg of body weight was presented for consultation with 3-weeks history of productive cough, vomiting and weight loss. The complementary exams showed peripheral eosinophilia, bronchointersticial pulmonary pattern on radiography and eosinophils infiltration on cytology of BAL.[...](AU)

RESUMO

Proventricular dilatation disease (PDD) is a lethal and important disease of captive psittacine birds, and affects a wide range of species, including endangered ones, and lacks an effective treatment. This report describes PDD in three blue-and-gold macaws (Ara ararauna) in southern Brazil. All three macaws originated from the same aviary and presented similar clinical signs including anorexia, apathy, emaciation and prostration. At necropsy, one of the macaws presented an enlarged proventriculus. Histologically, lymphoplasmacytic infiltrates was observed in the ganglia and nerves of the esophagus, crop, proventriculus, ventriculus, heart, adrenal glands, and adrenal medulla of all three cases. Two macaws had meningoencephalomyelitis and one had myocarditis. Immunohistochemistry identified PaBV antigen in the brain, proventricular, ventricular ganglia, and epicardial ganglia, and cardiomyocytes of all three macaws.(AU)

A doença da dilatação proventricular (PDD) e uma importante e fatal doença de psitacídeos de cativeiro, que afeta uma grande variedade de espécies e não tem um tratamento efetivo até o momento.

Todas as três araras eram provenientes do mesmo criatório e apresentaram sinais clínicos semelhantes incluindo anorexia, apatia, emaciação e prostração. Na necropsia, uma das araras apresentou proventrículo dilatado. No exame histopatológico, infiltrados linfoplasmacitários foram observados em gânglios e nervos do esôfago, inglúvio, proventrículo, moela, coração, glândulas adrenais e rins de todos os casos. Adicionalmente, meningoencefalomielite foi observada em duas araras e miocardite em uma. A imuno-histoquímica identificou antígenos de PaBV no encéfalo, coração, proventrículo e moela de todos os casos.(AU)

RESUMO

Eosinophils are cells of the immune system that have several important functions including phagocytosisof microorganisms, antigen presentation, contribution to chronic inflammation, and immunity againstparasites. The hypereosinophilic syndrome (HES) is a rare disease in humans that is characterized bypersistent eosinophilia (over six months) and variable eosinophil infiltration in organs such as the lungs,spleen, liver, lymph nodes, bone marrow, and gastrointestinal tract. Once in the tissues, these cells cancause damage by various mechanisms such as release of cytotoxic oxygen free radical and proteins. Noetiology has yet been established for HES. The clinical signs vary and relate to the organs involved.In veterinary medicine, the disease has been described in cats, but rarely in dogs, with Rottweilersapparently more predisposed to developing the disease. Owing to the small number of cases reportedin the veterinary literature, the prognosis of this disease and the most appropriate treatment options areunclear. Although it can be fatal in animals showing severe clinical symptoms, spontaneous remissionmay also occur. This study reports a case of HES in a Rottweiler in which the predominant clinical signwas abdominal effusion. We discuss the clinical and laboratory aspects of the disease.(AU)

Os eosinófilos são células do sistema imunológico que tem importantes funções, tais como fagocitose de micro-organismos, apresentação de antígenos, contribuição para a cronicidade do processo inflamatório e imunidade contra parasitas. A síndrome hipereosinofílica (SHE) é uma enfermidade rara que acomete seres humanos, caracterizada por eosinofilia periférica persistente (acima de seis meses) e infiltração variável de eosinófilos em diferentes órgãos, como pulmão, baço, fígado, linfonodos, medula óssea e o trato gastrointestinal. Uma vez nos tecidos, essas células causam danos por diversos mecanismos, como liberação de proteínas citotóxicas e radicais livres de oxigênio. Não é possível identificar uma etiologia nos casos de SHE. Os sinais clínicos são variáveis, e diretamente relacionados com os órgãos acometidos. Em medicina veterinária, a moléstia já foi descrita em felinos, mas raramente em cães, sendo que animais da raça Rottweiler são mais predispostos ao desenvolvimento da doença. Em função do pequeno número de casos descritos na literatura veterinária, a evolução da doença e as opções mais apropriadas de tratamento são pouco conhecidas. Embora alguns animais apresentem sinais clínicos graves, podendo evoluir para o óbito, a remissão espontânea também pode ocorrer. O presente trabalho tem por objetivo relatar um caso de SHE com sinal clínico predominante de efusão abdominal em um filhote de cão da raça Rottweiler, abordando aspectos clínicos e laboratoriais da enfermidade.(AU)

RESUMO

Background: The aural plaque is a papillomatosis variant that occurs in the inner surface of the auricular pavilion of equine. The disease is associated with economic losses in the equine sector, since it reduces the commercial value of the severely affected animals. However, there are few studies evaluating the occurrence of aural plaques in different breeds and equine populations in Brazil and in other countries. The aim of the present study was to evaluate the frequency, clinical and histological characteristics of the aural plaques in working horses from Lages, SC, Brazil.Materials, Methods & Results: Seventy-three crossbreed equines were used, including 48 males and 25 females between 1 and 25 years old, and that were used as working horses (traction) in the urban perimeter in the city of Lages, SC. The findings related to breed, age, sex, presence or absence of compatible lesions with aural plaques, anatomical location and lesion characteristics were evaluated and annotated. The lesions were photographed and drawn on paper to determine the size and distribution in the ear and were reevaluated for a period of two months with an interval of 30 days between each evaluation. The number of aural plaques was determined by manual counting in each auricular pavilion, which were divided into four quadrants (left and right upper, right and left lower). When the plaque was located in the median region of the quadrants, it was described in the region of the greatest location. To evaluate the histopathologic features, three equines that bearer typical lesions of aural plate were submitted to a biopsy.[...](AU)

RESUMO

Eosinophils are cells of the immune system that have several important functions including phagocytosis of microorganisms, antigen presentation, contribution to chronic inflammation, and immunity against parasites. The hypereosinophilic syndrome (HES) is a rare disease in humans that is characterized by persistent eosinophilia (over six months) and variable eosinophil infiltration in organs such as the lungs, spleen, liver, lymph nodes, bone marrow, and gastrointestinal tract. Once in the tissues, these cells can cause damage by various mechanisms such as release of cytotoxic oxygen free radical and proteins. No etiology has yet been established for HES. The clinical signs vary and relate to the organs involved. In veterinary medicine, the disease has been described in cats, but rarely in dogs, with Rottweilers apparently more predisposed to developing the disease. Owing to the small number of cases reported in the veterinary literature, the prognosis of this disease and the most appropriate treatment options are unclear. Although it can be fatal in animals showing severe clinical symptoms, spontaneous remission may also occur. This study reports a case of HES in a Rottweiler in which the predominant clinical sign was abdominal effusion. We discuss the clinical and laboratory aspects of the disease.
