Hyphema is an intraocular hemorrhage that can result from many ocular and/or systemic disorders. It is an important clinical sign, since it may appear in the initial stages of some diseases or haematological disorders, acting as an initial marker for early diagnosis. The hematologic disturbances that predispose animals to present hyphema are: Thrombocytopenia, von Willebrand Disease, Scott Syndrome, Disseminated Intravascular Coagulation and Hyperviscosity Syndrome due to Multiple Myeloma. Each of the differential diagnoses due to hematological changes from the appearance of hyphema in dogs shows clinical relevance and particular ocular signs

Study the semi-quantitative and quantitative technique in the diagnosis of catheter-related infections in newborns and to determine oxacillin resistance in Staphylococcus isolated. It was analyzed 353 catheter tips from 273 newborns in the Neonatal Unit of Hospital FMB. To confirm the diagnosis of infection, were analyzed the clinical data of newborns, the presence of at least one positive blood culture and growth of ≥ 1000 CFU/mL on quantitative culture and/or ³15 UFC on semiquantitative culture, with the same microorganism isolation (species and drug sensitivity) in blood culture and no other focus of infection except the catheter. The disk diffusion technique was used to check similarity of strains and resistance to oxacillin. Of the 353 tips analyzed, 39 were included in this study as the inclusion criteria. The semiquantitative culture was positive in 26 (66.7%) catheters and quantitative culture was positive in 24 (61.5%). Of 273 patients, 19 (6.9%) had a diagnosis of catheter-related bloodstream Infection (CR-BSI). Of the 19 episodes of CR-BSI, S. epidermidis was the predominant etiological agent (84.2%). The resistance to the antibiotic methicillin was found in 14 (73.7%) strains of Staphylococcus. The semiquantitative method was more sensitive (79%) compared with the quantitative method (63%). The use of antibiotics may have influenced the sensitivity of the quantitative method as the microorganisms present in the lumen are exposed to higher concentrations of antibiotics administered via the catheter

Infection with hepatitis C virus (HCV) is a worldwide problem of public health and who estimates 2.5% to 4.9% of infection by this virus among the population. This means that there are 3.9 to 7.6 million people at risk of developing cirrhosis or liver cancer. In Brazil, 20% to 58% of patients with chronic liver disease have antibodies to HCV (anti-HCV). To characterize the profile of patients undergoing treatment for hepatitis C in the Ambulatory General HC-FMB/UNESP, identify aspects of the disease and the phases of nursing process addressed during consultation. Transverse and descriptive study involving 38 patients undergoing treatment for Hepatitis C in Ambulatory General Area (Viral Hepatitis) in the period from July to September 2010. The population consisted of 38 patients, most of the males with completed higher education level, Catholic, married and aged predominantly between 41 and 60 years. Among the drugs used, we find the use of antihypertensive, antidepressant / anxiolytic and antidiabetic / hypoglycemic. With respect to specific medications used to treat hepatitis C, we found the use mainly of alfapeguinterferona 2b + ribavirin. The drugs used were complementary erythropoietin and filgastrim. There was a predominance of fibrosis 2 (F2) and genotype 1 (G1). Regarding the means of contamination, it was stressed blood transfusion and injection drug use. The most frequent drug reactions were decreased appetite, weight loss and discouragement. : The Nursing Process is considered a valuable tool in caring for patients with hepatitis C, because it works as identifying aspects of lifestyle, needs and potential of these patients and allows the deployment of humanized care strategies aimed at reduction of health hazards and improving the quality of life of these patients

Diabetic ketoacidosis (DKA) is one of the most serious complications of Diabetes Mellitus (DM) in small animals (SILVA, 2006). It is an acute metabolic disorder, potentially fatal, both in humans and in dogs and cats with DM (BRUYETTE, 1997), being related, mostly, to insulin-dependent diabetics (CHASTAIN, 1981; HUME et al., 2006). DKA is a medical emergency characterized by extreme metabolic abnormalities, including hyperglycemia, metabolic acidosis, ketonemia, dehydration and electrolyte loss (MACINTIRE, 2006) and its diagnosis may be established basically by the detection of ketonuria and metabolic acidosis (NELSON, 2009). The primary purposes of the treatment of DKA are intravascular volume restoration, dehydration, acid-base and electrolyte’s imbalances correction and blood glucose concentration reduction (BOYSEN, 2008). The treatment’s success depends of the clinical status at the time of diagnosis and of the introduction of an appropriate therapy to the conditions of each patient (CHASTAIN, 1981)

Os valores encontrados para a viscosidade sanguínea tendem a aparecer com diferenças significativas, de acordo com o sexo, avançar da idade e uso de substâncias. Pelo fato de o sangue ser um fluido não newtoniano, não podemos expressar sua viscosidade em termos absolutos sem que sejam levadas em conta as condições em que a mensuração é feita. Estudos anteriores destacaram a importância esta medida, considerando o efeito da idade, o uso de substâncias, bem como sua relação com Fluxo Sanguíneo Regional Cerebral, o que pode indicar correlação com declínios cognitivos. Entretanto, a prática médica carece ainda de um método simples e clinicamente prático para a verificação desta medida, além de valores de referência. Como passo inicial no sentido de padronizar os procedimentos e condições do processo de medição, avaliamos a quantidade mínima de amostra necessária para a medição da viscosidade sanguínea, utilizando este equipamento. Um total de 20 amostras de sangue foram coletadas de indivíduos saudáveis, entre 18 e 60 anos, em tubos com EDTA, e cada amostra dividida em 9 sub-amostras (de 600μl, 550μl, 500μl, 450μl, 400μl, 350μl, 300μl, 250μl e 200μl), totalizando, portanto, um total de aproximadamente 180 medições. A quantidade de 200 μl apresentou diferenças significativas com relação à primeira medida obtida, quando comparada com todas as demais quantidades (p<0,001), o que indica que com o uso desta quantidade, não é possível obter resultados confiáveis, pois existe alteração nos valores de VS obtidos relacionada à quantidade de material utilizado. Considerando a menor quantidade, bem como, que estivesse dentro da faixa de variação aceitável de 0,2 mPa.s, e a qual não apresentasse diferença significativa quando comparadas às demais (p>0,05), foi verificada a quantidade de 250 μl como a mais eficiente...

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

O conteúdo “Grupos sanguíneos” é abordado principalmente no ensino de biologia no Ensino Médio e está atrelado a diversas questões biológicas relevantes ao ensino básico. Além disso, sabe-se que esse tema é de cunho abstrato aos alunos, o que muitas vezes dificulta a apropriação do conteúdo pelo aluno. Nesse contexto, se torna relevante a elaboração de materiais que contribuam para um melhor processo de ensino e aprendizagem desse tema, além da incorporação da dimensão lúdica no universo escolar. Assim, a proposta do presente trabalho foi a elaboração de dois modelos didáticos de célula que facilitem a visualização da relação direta existente entre os genes responsáveis pela manifestação dos antígenos do sistema ABO, os genótipos dos diferentes indivíduos e as possibilidades de transfusão sanguínea existentes dentro de cada grupo sanguíneo. Além disso, foi construído um jogo didático de perguntas e respostas que envolvem os conhecimentos adquiridos durante a explanação teórica do professor com o intuito de fixação do conteúdo. O conteúdo fornecido neste trabalho foi baseado em livros didáticos, possibilitando aulas com conteúdo programático adequado e evitando erros conceituais
