    Echocardiography is the standard modality used to assess dogs with pulmonary valve stenosis (PVS). Right ventricular (RV) dysfunction is frequently observed in dogs with PVS. However, the importance and utility of echocardiographic assessment of RV function in the PVS dogs is not yet fully understood. The purpose of this study was to evaluate the usefulness of echocardiographic parameters in the assessment of RV function using 2-dimensional echocardiography and pulse Doppler imaging in 7 dogs with PVS and to compare these parameters with echocardiographic parameters in 10 healthy beagle dogs. Compared with the healthy beagle dog group, the PVS group had a significantly higher eccentricity index, a significantly lower tricuspid annular plane systolic excursion, a significantly lower ratio of trans-tricuspid early diastolic wave velocity to atrial contraction wave velocity, and a significantly higher ratio of diastolic pulmonary artery to aorta. The present study reports a correlation between the PVS and the echocardiographic parameter of RV function. Echocardiography is useful for noninvasive estimation of cardiac function in dogs with PVS.

    Forty-five dogs diagnosed with urticaria and treated at an animal hospital in Fukui-shi from June 2018 to January 2014 were analyzed. The following factors were included in the analysis: breed, sex, age, clinical symptoms, trigger factors, medical history, treatment, and progress. The incidence of the disease in the present study was 0.3% (45/14, 312). French bulldogs showed the highest incidence of any breed at 1.3%. The incidence in females was 2.1 times higher than that in males, and the incidence in contraceptive females was 2.5 times higher than that in non-contraceptive females. The average age was 5.2 years. The incidence in younger age animals was higher than that in older age animals. Clinical symptoms, such as angioedema of the eyelids and lips, were observed in 35 of 45 dogs with urticaria. The trigger could not be identified in 20 dogs (44.4%). In contrast, urticaria triggered by a change in side meal or staple food was identified in 14 dogs (31.1%), and by a combination of vaccines, plants, and drugs . The medical histories included atopy and allergic dermatitis (n = 18 : 40.0%), immune-mediated diseases (n = 3 : 6.7%), and recurrent urticaria (n = 5 : 11.1%). There were 19 (42.2%) dogs without any relevant history.

    We looked into the diagnostic methods and treatment of three rabbits that had refractory otitis externa with subcutaneous abscess in the root of the ear, as diagnosed by examination, X-ray, otoscope, micro-CT and angiography micro-CT. As the results of examination showed, all subcutaneous abscesses were breaking out with chronic otitis externa and media. Transformations of the tympanic cavity, such as thinning, expanding, luxury callus formation in the ventrolateral direction, and partial destruction, were evaluated by micro-CT and angiographic micro-CT. Early diagnosis and treatment are important to prevent intractable progressive tendency . Conventional therapies, such as ear canal cleaning and pressure drainage are likely to worsen the condition. Surgical treatment is effective against the subcutaneous abscess in the root of the ear.
