OBJECTIVE Considering the highest rate of morbidity and mortality in diamniotic monochorionic twins, the authors evaluated and compared the adverse obstetric and perinatal outcome in twin pregnancies according to chorionicity. PATIENTS AND METHODS A retrospective study was conducted in all twin deliveries that occurred in the Obstetric Unit of Maternidade(More)
UNLABELLED Obesity has a rising prevalence in children and adolescents, affecting 30% of the paediatric population in Portugal.

Few articles on renal involvement as an initial presentation of sarcoidosis have been published in the literature. CASE PRESENTATION A 26-year-old Caucasian woman presented with acute renal failure as an initial manifestation of(More)
In this paper we present a primal-dual interior-point algorithm to solve a class of multi-objective network flow problems. More precisely, our algorithm is an extension of the single-objective primal-dual infeasible and inexact interior point method for multi-objective linear network flow problems. A comparison with standard interior point methods is(More)

Fat Embolism (FE) develops in 90% of all bone fractures. Fat Embolism Syndrome (FES) is a serious manifestation of FE with an incidence of 0.5-2.0% among all long bone fractures. It is believed to be caused by the toxic effects of free fatty acids but still, there is considerable controversy over both the source of fat emboli and their mode of action [1].(More)
Between January of 1987 and December of 2001 were born 1243 twins related to 609 multiple pregnancies, in Maternidade Bissaya-Barreto. Data were grouped in periods of three years and several parameters were studied. The rate of multiple gestation has increased probably due to the contribution of the assisted conception techniques, and to the increase of the(More)
