ABSTRACT
This epidemiological study was designed to find out the incidence and factors associated with the occurrence of intraosseous lesions diagnosed at a Reference Centre in Brazil. We included all patients diagnosed with intraosseous lesions (cyst, tumour, bone-associated lesion, and periapical disease) during the period 2006-2017, and analysed the association between some sociodemographic and clinical variables and the types of lesion. There was a total of 290 intraosseous lesions, the most common being odontogenic cysts. There was a significant association between age and odontogenic tumours (p=0.001). In relation to the histopathological diagnosis, root cysts were the most common (n=57), followed by dentigerous cysts (n=26). The lesions studied were seen most often in women between the second and fourth decades of life, odontogenic cysts being the most common type found. We know of few publications of similar epidemiological work, either in Brazil or in the rest of the world, so we suggest that more such studies are made.

This paper presents electrocardiographic values in 25 Holstein calves using the standard bipolar limbs leads (I, II and III), augmented unipolar limb leads (avL, avR and avF) and a bipolar chest lead (V10 subscript). Two groups with different ages were compared (newborn - 18 to 72 hours and calves - 27 to 33 days old). It was concluded that no differences between age groups in P, Q, R, S and T waves, in the PR, QRS, QT and ST intervals and in axis orientation were observed

O objetivo deste trabalho foi analisar e comparar os registros eletrocardiográficos de cäes clinicamente normais, obtidos pelos métodos convencional, computadorizado e pela leitura direta do registro computadorizado impresso, visando padronizar o método informatizado e confrontá-lo com o convencional. Concluiu-se que existem diferenças quanto a amplitude e duraçäo da onda P e duraçäo do complexo QRS entre diferentes métodos, especialmente em relaçäo ao computadorizado, devendo-se sempre levar em consideraçäo esse fato durante a interpretaçäo dos exames
