Detecção dos genes de Biofilme, da leucocidina Panton-Valentine e da resistência a Meticilina em amostras de Staphylococcus aureus e Estafilococos Coagulase-Negativa

Uma coleção de 57 amostras de Staphylococcus aureus e 30 de estafilococos coagulasenegativa isoladas de recém-nascidos (RN) foram estudadas em relação à presença dos genes pvl, mecA e ica. Das 57 amostras de S. aureus, 31,6% apresentaram o gene mecA e 17,5% os genes pvl, sendo que dentre estas somente uma amostra foi mecA e pvl positiva. Os ECN apresentaram 36,7% de amostras mecA positivas, 93,3% ica positivas e nenhuma amostra pvl. Foi observada uma queda no número de amostras resistentes à meticilina no período de 1991-2005 para os S. aureus e também no período de 1990- 1996 para os ECN, porém a diferença não foi significativa. Também foram estudadas dez amostras de S. aureus isoladas de fossa nasal e nenhuma apresentou o gene mecA ou pvl. Já entre as dez amostras de ECN isoladas de fossa nasal, todas apresentaram o gene 11 ica, porém nenhuma foi resistente à meticilina. A análise dos dados clínicos dos RN revelou que o uso de cateter e outros corpos estranhos aumentam o risco de infecção por S. aureus e ECN. Assim, a produção de biofilme por ECN foi um importante fator de virulência presente em mais de 90% das amostras, confirmando a importância deste na ocorrência de infecções relacionadas com cateteres, e, apesar dos genes mecA e pvl estarem presentes concomitantemente em apenas uma amostra de S. aureus, esta revelou ter importância significativa

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

Manejo das fraturas nasais com manutenção das vias aéreas superiores

Nasal fractures are extremely frequent. The nasal bones are the third most frequently fractured bones in the human skeleton. This is due to their prominent position on the face and to the diminished bone thickness. As a result, weak forces can cause nasal fractures, while stronger forces can comminute the nasal bones. In general, assaults, falls and sports injuries are the etiologies most commonly involved in nasal trauma. The diagnosis of such fractures is basically clinical and their treatment is usually by closed reduction with good results reported in all the relevant literature. Thus, the aim of this paper is to report a modification of the closed reduction technique for the treatment of these fractures.

Displasia ectodérmica hipohidrótica: un síndrome de interés para la odontología

Hypohidrotic ectodermal dysplasia (HED) is a rare disease of genetic etiology. The most frequent form is of recessive linked to X-chromosome inheritance with affected male and female carriers. It can occur through autosomal mutations, of the gene EDA1 gene being responsible for the majority of the cases. It is characterized by the triad: hypohidrosis, oligodontia and hypotrichosis. We present two cases of patients with HED in which we observed characteristic signs of this syndrome: delicate skin, sparce hair, eyebrows and eyelashes, periorbital wrinkles, perioral and periorbital hyperpigmentation, prominent lips, in addition the patient in case 2 also present the depressed nasal bridge. We also found decreased salivary and lacrimal secretion and maxillary hypoplasia in both cases. At the oral examination in case 1 the upper right and left deciduous canines and lower right deciduous canine were present, and in case 2 the upper and lower (right and left) deciduous canines and two upper (one right and other left) permanent incisors were present with altered morphology, all of these dental elements were healthy. The early dental treatment of patients with HED, especially in the presence of oligodontia, as observed in our cases, is important not only to provide a better quality of life for these patients in the short term, but also an attempt to minimize the changes in facial growth to which these patients are subject.

Primary bilateral guttural pouch empyema in a two-month-old foal

The present report describes a 2-month-old foal which signs of respiratory infectious disease, bilateral retropharyngeal swelling and nasal mucopurulent discharge, suggesting guttural pouch empyema. The owners reported that the foal lived in a herd that experienced an outbreak of strangles. Foals younger than 3 months are usually protected against infectious diseases, however in this case, the foal was exposed to an environment heavily populated by Streptococcus equi equi during the outbreak of strangles. Although uncommon in such young animals, the foal was infected and developed a primary bilateral guttural pouch empyema, without signs of lymph nodes alteration
