Sistema de cálculo para determinação do tempo de exposição em radioterapia veterinária

Radiotherapy in veterinary practice is already known and widely distributed in large specialized centers of developed countries. In early 2000, there were about 30 radiotherapy equipment specifically designed for the veterinary clinic in the United States. In Brazil, the veterinary radiotherapy is still confined to research in universities, where most of the procedures is radiation therapy performed with superficial x-ray machines, with a voltage between 50 and 150 kVp, focus-distance surface (DFS) between 20,0cm and 40,0cm. As that occurs in human medicine, new research strengthens the development and prospects for the use of radiotherapy as a safe option for treating cancer in animals. This paper presents a methodology for calculating the exposure time for superficial radiotherapy procedures in veterinary medicine for small animals (dogs and cats). The dosimetric parameters of X-rays are determined using a spreadsheet tool for Microsoft Office Excel, developed in this paper for a device Dermopan 2, Veterinary Hospital of UNESP in Araçatuba. Using the worksheet helps the veterinarian to determine the time of exposure to radiation determined for each clinical case, optimize the workflow for professionals in veterinary radiotherapy procedures, which often lack the medical physics in team and at the time of radiotherapy. The correct use of spreadsheet decreases the chances of errors in dose rates of radiation, providing a higher quality of care

Generalized systemic cryptococcosis in a dog after immunosuppressive corticotherapy

Um cão da raça Boxer, macho, com 2 anos e 11 meses de idade foi encaminhado ao hospital veterinário com histórico de distúrbio gastroentérico de dois meses de duração, apatia, hiporexia, emagrecimento progressivo e deficiência visual. Ataxia e vocalização foram observadas posteriormente. O animal estava sendo tratado em outra clínica veterinária com antibióticos e doses imunossupressoras de corticóides, direcionados ao controle de provável enterite alimentar. A morte ocorreu após cinco dias. As observações macro e microscópica revelaram tratar-se de criptococose sistêmica, atingindo trato digestório, olhos, SNC, rins, pâncreas e linfonodos. O presente relato enfatiza a infecção fúngica criptocócica quanto aos seus aspectos grastrointestinais iniciais a serem considerados no diagnóstico clínico, ressaltando a imunossupressão induzida pela corticoterapia.

Seroprevalence of Toxoplasma gondii infection in cats from Curitiba, Paraná, Brazil

A toxoplasmose é uma zoonose de distribuição mundial, causada pelo protozoário Toxoplasma gondii que infecta os vertebrados de sangue quente. Este estudo objetiva estabelecer a prevalência de anticorpos anti-Toxoplasma gondii e o estudo de associação em uma população de gatos domésticos atendidos em uma clínica veterinária exclusiva de gatos localizada em Curitiba, estado do Paraná, Brasil. As amostras de soro foram obtidas e processadas pela reação de imunofluorescência indireta IgG. Títulos de anticorpos foram encontrados em 46/282 (16,3%) das amostras analisadas, com título de 16 em oito gatos, 64 em 23, 256 em 14 e 1024 em um gato. Diferenças estatísticas não foram encontradas no estudo de associação entre idade, gênero e região da cidade (p > 0,05). Nenhuma diferença significativa foi encontrada para qualquer variável, quando comparando a soropositividade com a ocorrência do possível fator de risco. A soroprevalência foi relativamente menor quando comparada a outras regiões brasileiras, provavelmente por serem gatos de proprietários, que tinham hábito domiciliado e alimentação restrita baseada em alimentos industrializados, com acesso restrito a rua e sem acesso a caça. em conclusão, a baixa soroprevalência de toxoplasmose felina pode estar relacionada a gatos com proprietários devido aos cuidados alimentares e acesso restrito à rua, e também pode estar associada à baixa exposição ambiental local

Diagnóstico de gestação em cadelas: aspectos radiográficos e ultrassonográficos

The modernization of image equipaments associate to the veterinary professionals qualification allowed an advance in diagnosis veterinary medicine, and, consequently, in premature pregnancy diagnosis in bitches. Currently, owners and creators search for information related to pregnancy detection, fetal development and viability and litter size determination. Through diagnosis methods as radiology and ultrasonography, associated to clinics aspects, the diagnosis of early pregnancy become more acurated and precise, allowing more quality in the accompaniment of prenatal of these bitches. Ultrasonographic exams help the accompaniment of these pregnancies through of visuals recourses, which can supply information related to pregnancy detection, embrionary and fetal development, fetal viability e litter size determination through fetals mensurations. The radiographic study has as principal indication the fetal counting, and has been the most acurated for this analyses. It may be done after the da s after the luteini ing hormone surge, when occurs the fetal mineralization. Due to its importance in the present time and in small animals clinic, the objective of this study is to discuss the main radiographics and ultrassonographics aspects of the diagnosis of pregnancy in bitches

Utilização da acupuntura no tratamento de cães com discopatia intervertebral

The intervertebral disc diseases have a high casuistic in clinical routines veterinary among dogs. These conditions can cause pain, paresis or paralysis of limbs depending on the degree of injury. Clinical signs are not limited to the intervertebral disc, other anatomical parts are included. In conventional medicine, treatment may be surgical or clinical, by the use of corticosteroids with muscle relaxants. Acupuncture was an alternative to treating these diseases due to its anti-inflammatory and analgesic effects. Although there are few studies for the treatment of discopathies, acupuncture triggers the release of substances such as dynorphins, beta-endorphins and serotonin, among others; that act inhibiting somatic and visceral pain. Electroacupuncture is used to potentiate the effects of acupuncture. It can be performed with different frequencies according to the clinical evolution. However there are different opinions related to the greater efficacy in relation to acupuncture. The restraint and monitoring of the treated animal are important factors for its recovery. The association between acupuncture and conventional treatment (surgical or clinical) achieved better results than acupuncture alone. This proves that acupuncture can be considered an option in order to minimize the complications of surgery or assist in patient recovery

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
