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

Beta talassemia menor: aspectos clínicos e laboratoriais

As alterações que afetam as hemoglobinas estão relacionadas à síntese estrutural ou quantitativa dos aminoácidos que compõem as diferentes cadeias globínicas (α/β). Existem inúmeras causas que podem resultar nessas alterações, dentre elas as mutações. A talassemia é um dos distúrbios genéticos mais frequentes do homem e mais difundidos no mundo. Fatos históricos, como imigração e colonização populacionais de diferentes partes do mundo, contribuíram para a difusão da patologia em outras localidades, incluindo o Brasil. A forma de manifestação clínica e laboratorial da talassemia do tipo beta menor (BTT), foi objeto de estudo nesta revisão bibliográfica, pois embora seja uma patologia que não mostra claramente manifestações sintomáticas, seus aspectos clínicos e laboratoriais são muito relevantes. A importância do diagnóstico laboratorial das anemias microcíticas e hipocrômicas presentes, tanto em indivíduos portadores de deficiência de ferro como em beta talassêmicos menor, é um ponto chave quando nos referimos a esses parâmetros, pois os índices HCM e VCM apresentam-se com valores extremamente reduzidos (<24 pg e <70 fL) e a quantidade de glóbulos vermelhos muito aumentados (> 5,0 milhões/μL), na beta talassemia menor em comparação à deficiência de ferro. Portanto os valores contidos no hemograma bem como a presença da inclusão citoplasmática ponteado basófilo e morfologia das hemácias observadas em análise de extensões sanguíneas coradas, é de grande valia na suspeita da beta talassemia menor, tornando-se ponto importante na sugestão da realização de eletroforese de hemoglobina para confirmação do diagnóstico da beta talassemia menor, devido ao aumento quantitativo da Hb A2.

Is cryptosporidiosis an underestimated disease in cats?

Studies on the occurrence of Cryptosporidium spp. in cats are still scarce. In this literature review, we address epidemiological and clinical aspects, as well as diagnostic methods, therapeutic behavoiur, and control and prevention measures for this disease in cats, with the aim of investigating if cryptosporidiosis is an underestimated disease in the laboratory routine and in small animal medical clinics.

Comparison of imaging methods for diagnosis of renal tumors and their calcifications

Background: To establish the best methodology for diagnosis and management of patients with solid and complex renal masses by comparing the costs and benefits of different imaging methods and to improve differential diagnosis of these benign and malignant lesions, particularly by investigating tumour calcifications. Methods: We performed a prospective study on 31 patients with solid or complex masses by submitting them to Abdominal Ultrasonography (US), Doppler Ultrasonography of the renal mass (US Dop), Computed Tomography (CT), and Magnetic Resonance Imaging (MRI). Results: We found 28 patients with malignant and three with benign masses. Of the 28 malignant, 17 showed calcifications at CT; 16 central and one was of the pure peripheral curvilinear type (egg shell). Excretory Urography (IVP) had a significantly lower detection rate for central calcifications than both US and CT. Benign and malignant masses appeared as described in literature, with US, CT and MRI showing high sensitivity and specificity in renal tumor diagnosis. The exception was US Dop where we obtained lower sensitivity for the characterization of malignant tumor flow. Conclusions: In this series we were surprised to find that CT revealed central calcifications in 51.6% of patients, all with malignant lesions, while, literature reports a frequency of calcification in renal cell carcinoma between 8 and 22%, in studies using abdominal films and EU (IVP). This finding is of great importance when we consider that these calcifications occur particularly in malignant neoplasms. As a result of comparing these different imaging methods we have developed a better methodology for renal tumor investigation.

Clinical and epidemiological aspects of feline leishmaniasis in Brazil

Dor orofacial

The orofacial pain, also known by the generic term dysfunction, is highly prevalent in the general population, causing great discomfort to the patients. For this reason, there is great importance of dentist’s participation in practice and in the process of proper diagnosis of this disease, which in modern times has become increasingly important as guides the best treatment. Thus, this study was aimed to review the main causes, diagnosis, main symptoms and treatment modalities, to serve as a guide to the dentist. Moreover, it also aims to review the main etiologic factors commonly associated, as emotional stress and muscular hyperactivity, to clearly identify signs and symptoms, so the dentist is able to realize simple treatment in your particular office or recognizes complex cases that could be send for treatment to multidisciplinary teams.

Visceral leishmaniasis in Brazil: trends and challenges

The urbanization of visceral leishmaniasis in Brazil has been related to environmental changes, migration, interaction and spread of sylvatic reservoirs and infected dogs to areas with no transmission, and adaptation of the vector Lutzomyia longipalpis to the peridomiciliary environment. From 1980 to 2005, Brazil recorded 59,129 cases of visceral leishmaniasis, 82.5% of which in the Northeast region. Visceral leishmaniasis gradually spread to other regions of the country: in 1998 these other regions reported 15% of all cases, but by 2005 this proportion had increased to 44%. From 1998 to 2005, indigenous cases were reported in 1,904 different municipalities of the country (34.2%). Reservoir and vector control pose major challenges for disease control, since there is a need for better knowledge of vector behavior in urban areas, and control activities involve high operational costs. In recent years the Brazilian Ministry of Health has supported research on the laboratory diagnosis of infection and disease in humans and dogs, treatment of patients, evaluation of the effectiveness of control strategies, and development of new technologies that could contribute to the surveillance and control of visceral leishmaniasis in the country.

Las radiaciones ionizantes en la educación médica de grado de la Universidad Nacional de Cuyo

Las irradiaciones médicas constituyen la contribución más importante a la exposición humana a radiaciones ionizantes de origen artificial. Las estadísticas mundiales indican una tendencia creciente en el número anual de estas prácticas en función del desarrollo de nuevas técnicas de diagnóstico por imágenes, de la aplicación de nuevos fármacos marcados con diversos isótopos y de avances en los tratamientos antineoplásicos. Debido a esta amplia difusión, la Protección Radiológica (PR) se ha convertido en un tema relevante para las sociedades científicas y los organismos reguladores. En este sentido, la mayor parte de los países europeos ha implementado planes de acción para la protección radiológica del paciente. Un ejemplo de ello lo constituye la guía PR/116 elaborada por la Comisión Europea en el año 2000, que recomienda la implementación de un curso en PR en las escuelas de Medicina y Odontología. En consecuencia, el propósito general de esta investigación fue describir y analizar críticamente la situación actual de la enseñanza de contenidos referidos al uso de las radiaciones ionizantes en la carrera de Medicina de la Facultad de Ciencias Médicas de la Universidad Nacional de Cuyo. Los principales resultados muestran que no existe una obligación curricular que presente entre sus contenidos mínimos la enseñanza de la PR, como tampoco de conocimientos básicos de Física de la radiación. Además, tanto la PR como los temas ambientales relativos al uso de radiaciones ionizantes en Medicina no se desarrollan según lo recomendado por Organismos Internacionales especializados. Teniendo en cuenta que muchos métodos de diagnóstico por imágenes utilizan radiaciones ionizantes, se sugiere la inclusión de esta temática en el plan de estudio de la carrera de Medicina. El objetivo es incorporar la cultura de la radioprotección en la formación del futuro profesional y, en consecuencia, reducir la ejecución de prácticas injustificadas que atentan contra la salud individual y ambiental.
