Methods: A total of 262 consecutive patients referred for prostate biopsy based on abnormal digital rectal examination and/or elevated total PSA (tPS...
Imaging 3D seismic velocity along the seismogenic zone of Algarve region (south...
Rocha, J; Bezzeghoud, M; Caldeira, B; Dias, N; Borges, JF; Dorbath, L; Carrilho, FThe present seismic tomographic study is focused around Algarve region, in South of Portugal. To locate the seismic events and find the local velocity structure of epicentral area, the P and S arrival times at 38 stations are used. The data used in this study were obtained during the Algarve campaign which worked from January/2006 to July/2007. The preliminary estimate of origin times and hypocentral coordinate...
Carcinoma pancreático de células gigantes de tipo osteoclástico
Pimentel, A; Leitão, S; Dias, N; Cipriano, MA; Leite, J; Santos, R; Nascimento-Costa, JMInitially described 40 years ago (Rosai), the undifferentiated osteoclastic-type giant cell carcinoma (IOGCC) is a variant of ductal adenocarcinoma and accounts for less than 1% of exocrine pancreatic tumors. Its extreme rarity, with consequent existence of few reports and clinical experience, leads to the arousal of doubts with regard to its histogenesis, types of approach and therapeutical attitudes. It is im...

The determination of susceptibility to measles, rubella, mumps and chickenpox i...
Oliveira, J; Dias, N; Ferreira, T M; da Cunha, S; Costa, D; Côrte-Real, R; Meliço-Silvestre, AWe present an epidemiological and serological study in 286 health care students. We found susceptibility for measles in 11.7% individuals (95% confidence interval (95% CI): 8.0-15%), for rubella: 6.7% (95% CI: 3.8-9.6%) for mumps: 12.7% (95% CI: 8.0-16.6%) and for varicella 8.5% (95% CI: 5.3-11.7%). Compared to a similar study, performed in 1992 in a population of health care workers, we found an increasing sus...
