RESUMO

The association between chronic kidney disease (CKD) and pulmonary pathophysiological changes is well stablished. Nevertheless, the effects of aerobic exercise (AE) on lungs of CKD need further clarification. Thus, Swiss mice were divided in control, AE, CKD, and CKD + AE groups. CKD was induced by 0.2% adenine intake during 8 weeks (4 weeks of CKD induction and 4 weeks of AE). AE consisted in running on treadmill, at moderate intensity, 30 min/day, 5 days/week, during 4 weeks. Twenty-four hours after the last training day, functional capacity test was performed, and 48 h after the test, mice were euthanized. CKD mice showed a significant increase in urine output, serum urea, and creatinine concentrations, and decreased body weight and urine density, besides oxidative damage (p = 0.044), edema area (p < 0.001), leukocyte infiltration (p = 0.040), and collagen area in lung tissue (p = 0.004). AE resulted in an increase of distance traveled (p = 0.049) and maximum speed (p = 0.046), increased activity of catalase (p = 0.031) and glutathione peroxidase (p = 0.048) in lungs, increased levels of nitric oxide (NOx) in serum (p = 0.001) and bronchoalveolar lavage fluid (p = 0.047), and decreased kidney histological injury (p = 0.018) of CKD mice. However, AE also increased oxidative damage (p = 0.003) and did not change collagen content or perivascular edema in lungs (p > 0.05) of CKD mice. Therefore, AE attenuated kidney injury and improved antioxidants defenses in lungs. Despite no significant changes in pulmonary damage, AE significantly improved physical performance in CKD mice.

RESUMO

Idiopathic renal hematuria is diagnosed in situations where the cause of hematuria is not clear, even after ruling out all possible differential diagnoses. A 14-year-old female Cocker Spaniel with continuous hematuria as the only clinical sign for two months. Concomitant changes were ruled out by blood tests, urinalysis, and abdominal ultrasonography. It was evidenced that hematuria originated from the left kidney through ureteral catheterization and the diagnosis of idiopathic renal hematuria was determined by excluding other possible causes of renal hematuria. Idiopathic renal hematuria is a rarely reported disease but has great importance as a differential diagnosis in cases where the main clinical sign is hematuria.(AU)

A hematúria renal idiopática é diagnosticada em situações onde a razão da hematúria não é esclarecida, descartando-se todos os possíveis diagnósticos diferenciais. Um cão, fêmea, Cocker Spaniel com 14 anos de idade manifestou hematúria contínua como único sinal clínico, por dois meses. Foram descartadas alterações concomitantes, por meio de exames de sangue, urinálise e ultrassonografia abdominal. A hematúria proveniente do rim esquerdo foi evidenciada através de cateterização ureteral e o diagnóstico de hematúria renal idiopática foi obtido por meio da exclusão de outras possíveis causas de hematúria renal. A hematúria renal idiopática é uma doença pouco relatada, no entanto apresenta grande importância como diagnóstico diferencial nos casos onde o principal sinal clínico é a hematúria.(AU)

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

Os gatos estão entre os animais de estimação mais comuns no mundo inteiro e é cada vez mais estreito o seu convívio com os humanos, o que torna os estudos epidemiológicos sobre as doenças que afetam esta espécie de grande importância. Portanto este estudo teve como objetivo determinar a ocorrência de doenças infecciosas em gatos atendidos no Hospital de Clínicas Veterinárias (HCV) da Universidade do Estado de Santa Catarina (UDESC), no município de Lages, assim como identificar os principais sinais clínicos apresentados para cada uma delas. Para isso, foram revisados 825 prontuários de consultas clínicas de gatos, arquivados no HCV, do período de fevereiro de 2013 a julho de 2015. Entre os prontuários revisados, 32/825 (3,88%) apresentaram diagnóstico de doenças infecciosas. A distribuição das enfermidades classificadas como infecciosas foram as seguintes: virais 24/32 (75,0%); bacterianas 4/32 (12,5%); fúngicas 3/32 (9,37%) e causada por protozoário 1/32 (3,13%).  Entre as doenças infecciosas a mais ocorrente foi o vírus da leucemia felina (FeLV) [13/33 (39,39%)], aonde as manifestações clínicas encontradas foram a anemia (6/12 [50,00%]), seguida pela leucemia (4/12[33,33%]) e linfoma (2/12[16,67%]). Também foram obtidas a ocorrência das doenças infecciosas de acordo com alguns critérios de seleção, como raça, idade, sexo, acesso à rua, contato com outros animais e status de vacinação. Gatos machos, não vacinados, com acesso livre à rua e contato direto com outros felinos estiveram em maior número dentre os doentes, o que demonstra a íntima relação da falta de cuidados básicos de saúde desses animais com a ocorrência das doenças infecciosas na espécie.(AU)

Cats are among the most common pets in the world. The close relationship between human beings and cats supports the importance of epidemiologic studies on feline diseases. Therefore, this study showed the occurrence of infectious diseases in cats at the Veterinary Clinics Hospital (HCV) of Santa Catarina State University (UDESC), in Lages (SC, Brazil), as well as identifying the major clinical signs presented in each affection. Hence, 825 medical records were reviewed, from February 2013 to July 2015. Among the reviewed records, 20/285 (2,42%) were diagnosed with infectious diseases. The distribution of infectious diseases was: viral 12/20 (60,00%); bacterial 4/20 (20,00%); fungal 3/20 (15,00%) and caused by protozoa 1/20 (5,00%). Among these infectious diseases, the most diagnosed agent was Feline Leukemia Virus (FeLV) [12/20 (60,00%)]. The most observed clinical signs were anemia (6/12 [50,00%]), followed by leukemia (4/12 [33,33%]) and lymphoma (2/12 [16,67%]). The study also showed the occurrence of infectious diseases according to some selection standards, for instance, breed, age, sex, outdoor access, inhabiting with other pets and vaccination status. The most affected group of animals were non-vaccinated male cats, which had direct contact with other felines and outdoor access, demonstrating the close relationship between the lack of health care and the occurrence of feline infectious diseases.(AU)

RESUMO

This study determined the occurrence of parvovirus and distemper in dogs treated at the Veterinary Clinics Hospital (HCV) of Universidade Estadual de Santa Catarina (UDESC). For such, 3198 medical records filed in the HCV, from February 2013 to July 2015, were reviewed.  From the records, 145 (4.53%) dogs were diagnosed with parvovirus (76 [2.38%]) or distemper (69 [2.15%]). The most common clinical signs of parvovirus were gastrointestinal signs (76 [100%]), having hematochezia as the most commonly observed (74 [97.37%]); for distemper, neurological signs (48 [69.56%]) were most frequently described and myoclonus had the highest occurrence (31 [64.58%]). Regarding complete blood count, the most observed variation in parvovirus was leukopenia by neutropenia and lymphopenia (20 [71.43%]). Distemper showed lymphopenia (28 [59.57%]). It was also observed that the occurrence of distemper and parvovirus were higher according to some selection criteria: breed, age, outdoor access, having contact with other animals and vaccination status. Young non-vaccinated dogs with outdoor access had the highest occurrence ratio. This study showed that viral infectious diseases presented low occurrence, and parvovirus was the most reported agent.(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

A bronquite crônica canina (BCC) é considerada uma das doenças respiratórias mais comuns em cães. Ela é caracterizada por tosse crônica e progressiva, com comprometimento da qualidade de vida do paciente. A enfermidade é causada por um processo inflamatório de origem desconhecida, sendo mais comumente observada em cães adultos a idosos de raças de pequeno porte. Casos graves da enfermidade são caracterizados por importantes alterações estruturais das vias áreas e podem evoluir para insuficiência respiratória e óbito. A despeito disso, as informações disponíveis na literatura sobre a moléstia são extremamente limitadas, e o tratamento preconizado, baseado em poucas evidências cientificas consistentes. O objetivo deste trabalho é realizar uma revisão da literatura sobre o tema, abordando os aspectos de etiopatogenia, sinais clínicos, exames subsidiários e tratamento da BCC.(AU)

Canine Chronic Bronchitis (CCB) is considered to be one of the most common chronic respiratory diseases of dogs. The hallmark of CCB is chronic and progressive cough that leads to poor life quality of the dog. Severe cases may progress to respiratory insufficiency and death. The cause is an inflammatory process of unknown origin. The disease is most common in adult and older dogs of small animal breeds. In severe cases, this chronic inflammatory process progresses to irreversible structural changes in the airways, resulting in respiratory failure. Despite this, information about the disease is extremely limited in the literature, and the recommended treatment is based on poor scientific evidence. Thus, the aim of this study is to review the subject and describe the etiology, pathophysiology, clinical features, complementary diagnosis and treatment of CCB.(AU)
