Estima-se que cerca de 2 mil milhões de pessoas estejam infectados pelo vírus da hepatite B (VHB) e que mais de 350 milhões sejam portadores crónicos. Os doentes que apresentam anticorpos para o antigénio core (Ac anti-HBc) com negatividade para antigénio de superfície (AgHBs), não têm hepatite crónica, mas contactaram com o vírus no passado. Este estado serológico corresponde, na maioria das vezes, a uma elimi...
Values of serum tartrate-resistant acid phosphatase ( TRAP) activity were obtained in adult dogs and its biological variability was assessed. Nine healthy skeletally mature Portuguese Podengo dogs were used for the determination of TRAP, total and bone alkaline phosphatase serum activities, and also to study their relationship with serum minerals, namely calcium (Ca), phosphorous (P), and magnesium (Mg). The se...

Background Progressive multifocal leukoencephalopathy (PML) is a demyelinating disease of the central nervous system, associated with immunosuppression states. As there are only some non-published documents concerning PML in HIV infected patients in Portugal, we pretend to characterize natural history of PML infection in a population of HIV patients. Methods We retrospectively reviewed, from 1992 to 2009, PML c...
