Pressão arterial em cães: uma revisão

The evaluation of blood pressure is an essential tool for veterinarian clinical practice and for monitoring anesthetized patients or patients in intensive care, because of its usefulness in diagnostics, treatment and monitoring of several diseases. Apart from the pathological factor, the blood pressure also suffers the influence of different variables, such as age, breed, gender, temperament (anxiety and stress especially during the treatment, “white coat syndrome”), disease state, physical activity and, with lower intensity, animal’s diet. One of the main indications of the evaluation of blood pressure is the observation of clinical changes resulting from hypertension in animals, which one is characterized by lesions in the nervous and cardiovascular systems, kidneys and eyes. Not least important, the evaluation of blood pressure is also essential in hypotensive states, which represent an imminent risk of death. The techniques used in measuring blood pressure correspond to invasive forms (direct) or non invasive (indirect), whose correlation has been the subject of study and improvement within the small animal clinic. Thus, the purpose of this review is emphasize the importance of measuring blood pressure within the veterinary clinic routine, studying the influence of variables associated or not with elevated blood pressure, comparing the different methods used to obtain the blood pressure

Avaliação das doses de cães submetidos a exames radiográficos de pulmão

This study aims to determine surface skin doses in dogs (with suspected pulmonary metastasis) submitted to chest X-rays using the technique of thermoluminescence dosimetry. Twenty seven exams from different dogs were performed at the Faculdade de Medicina Veterinária e Zootecnia da Universidade Estadual Paulista (FMVZ-UNESP/Botucatu). The doses were evaluated using thermoluminescent dosimeters of calcium sulphate doped with dysprosium (CaSO4:Dy) produced by the Instituto de Pesquisas Energéticas e Nucleares (IPEN-CNEN). The pulmonary metastasis exams are carried out in three projections, one dorsal-ventral and two lateral-lateral. During the procedures the projection thicknesses and source-skin surface distances were registered. To simulate the dog phantom the dosimeters were positioned in a cubic simulator (30x30x30 cm) of polymethylmethacrylate (PMMA) filled with water and irradiated according to the parameters of projections with the X-ray energies ranging from 45 to 70 kV. To estimate the surface skin dose the dose-response curves were obtained for X-ray energies of 50 and 70 kV using the diagnostic X-ray beam machine of the Instruments Calibration Laboratory of IPEN for doses of 1.5, 2.0, 2.5, 3.5 and 4.0 mGy. The main difficulty of this work was the dog immobilization that is reflected in poor-quality diagnostic imaging and, consequently, demands the repetition of the exams, which contributes to the increase of the doses received by the animals being studied and the clinical staff. The doses evaluated in this type of procedure are between 0.43 and 4.22 mGy. This research has shown to be extremely important for the assessment of doses involved in veterinary diagnostic radiology procedures, and as a parameter in the individual monitoring of pet’s owners who assist the animal positioning and occupationally exposed workers of the Department of Veterinary Radiology

Pênfigo Foliáceo em cães

Pemphigus complex in animals is considered rare, but not so when compared with the occurrence of other autoimmune diseases. Pemphigus Foliaceus in dogs is the most common varieties of pemphigus and is characterized clinically by intraepidermal pustules, starting on the face and ears, pads, groin, and may become multifocal or generalized in six months. As the pustules are very fragile, the lesions usually found are secondary, which may range from dry to collarettes epidermal crusting, and nasal depigmentation. The diagnosis is difficult because presents sintomatology similar to other diseases and laboratory diagnosis more precise through the histopathological examination of pustules integrate (biopsy), which are rarely found. The treatment, although of the individual treatment regimen, is based on treating opportunistic diseases and immunosuppressing the animal in order to decrease the production of autoantibodies. The drugs of choice depend on the clinical presentation, however is usually oral prednisone and azathioprine in the dog and combined immunosuppressive therapy. Should make use daily until the disease is inactive and gradually decrease the dose until have the minimum effective dose, preferably on alternate days for the remission of the disease. Prognosis of pemphigus varies according to disease stage and treatment established. Pemphigus foliaceus is less serious nonetheless might be fatal without treatment
