Introdução: O oncocitoma renal representa 5-7% das neoplasias primárias do rim, é diagnosticado em doentes assintomáticos e caracteriza-se por um comportamento benigno, sem invasão dos tecidos adjacentes ou metastização. O seu diagnóstico no decurso da gravidez é raro, havendo poucos casos descritos na literatura.
Caso clínico: Os autores apresentam o caso de uma nulípara de 32 anos com hipertensão arterial de difícil controlo diagnosticada às sete semanas gestacionais com internamento às 24 semanas por quadro de hipertensão crónica agravada com pré-eclâmpsia sobreposta, edema agudo
do pulmão e instabilidade hemodinâmica com necessidade de suporte ventilatório mecânico,
restrição do crescimento fetal e morte fetal. O estudo etiológico do quadro hipertensivo efectuado no período pós-parto permitiu demonstrar a existência de um tumor ...
The goal of the research plan is to contribute to an improved assessment of the seismic hazard in the Lower Tagus Basin (L.T.B.), in order to achieve that, we propose the introduction of realistic methods on the prediction of ground motion produced by moderate to large earthquakes in this area. This process involves the establishment of a structural 3D model and the evaluation of seismic potential of the faults in the studied area. The method employed involves modeling based in Finite difference Methods (FDM), done on a massive parallel computing system.
There is already a 3D velocity model (SWIBMOD2006 model and VFGEN program [1]) and a methodology for wave propagation of the SW of Portugal which is based on the Finite difference method and applied through the E3D program. The work we are currently developing is based in the previous...
BACKGROUND: In situ breakage of Implanon® is a rare occurrence with unknown clinical significance. Authors report two different cases of broken Implanon® of women attended at our Family Planning Clinic.
DISCUSSION: In situ implants may spontaneously and asymptomatically break, although some uncertainty relies on whether that situation has a real impact on the contraceptive effectiveness or on bleeding patterns. Even more, it can be argued if, as a result of an occurrence of that nature, the implant shall or shall not be removed before the envisaged 3-year period of effectiveness.
CONCLUSION: Currently, the clinical significance of implant breakage remains unknown. The decision to remove a broken or bent implant should be based on clinical judgements considering patients' wishes.
Uterine rupture during a trial of labor after previous cesarean (TOLAC) delivery is a rare, but serious complication. Several factors can increase the risk of uterine rupture, so the assessment of individual risks with adequate counseling is ne -
cessary. The initial signs and symptoms are usually nonspecific, hampering timely diagnosis and prompt delivery of the fetus,
necessary for optimal outcome. The purpose of this document is to review the risks factors for uterine rupture during TOLAC, as well as the current clinical value of the classically described premonitory signs and symptoms.
Infections during pregnancy are prevalent. A small number of cases, however, may be life-threatening. Sepsis may be associated
with multiple organ dysfunction and high mortality and it is one of the most common causes of direct maternal death
often associated with the inability to recognize the severity of the illness. Long-term morbidity associated with maternal
sepsis is significant and includes chronic pelvic inflammatory disease, chronic pelvic pain, bilateral tubal occlusion and infertility.
The impact on neonatal mortality is also substantial, with over one million infection-related neonatal deaths eve -
ry year. In the last few years, a vast number of clinical reviews of severe sepsis in pregnancy have been published, focusing
on the characteristics of pregnant woman, the establishment of a specific treatment and the relev...
Introdução: A Diabetes gestacional está associada a complicações maternas e perinatais.
Objectivo: Avaliar a influência da nacionalidade nos resultados obstétricos e perinatais em grávidas com Diabetes gestacional.
Metodologia: Estudo de todas as gestações simples consecutivas complicadas por Diabetes gestacional, vigiadas na nossa instituição em 2005-09 (n=921). Foram estabelecidos 2 grupos, um de grávidas portuguesas (grupo 1, n=730) e outro de grávidas oriundas de outros países (grupo 2, n=191). Avaliaram-se dados demográficos, factores de risco para Diabetes gestacional, hemoglobina glicosilada, necessidade de insulina, complicações hipertensivas, hidrâmnios, idade gestacional no parto, tipo de parto, peso ao nascer, índice de Apgar, internamento em unidade de cuidados intensivos neonatais e diagnóstico de Diabetes mellitus pós-p...
The authors present a case of a 27-year-old multiparous woman, with multiple thrombophilia, whose pregnancy was complicated with deep venous thrombosis requiring placement of a vena cava filter. At 15th week of gestation, following an acute deep venous thrombosis of the right inferior limb, anticoagulant therapy with low-molecular-weight heparin (LMWH) was instituted without improvement in her clinical status. Subsequently, at 18 weeks of pregnancy, LMWH was switched to warfarin. At 30th week of gestation, the maintenance of high thrombotic risk was the premise for placement of an inferior vena cava filter for prophylaxis of pulmonary embolism during childbirth and postpartum. There were no complications and a vaginal delivery was accomplished at 37 weeks of gestation. Venal placement of inferior vena cava filters is an attractive opti...
PURPOSE: To improve quality of newborn screening by tandem mass spectrometry with a novel approach made possible by the collaboration of 154 laboratories in 49 countries.
METHODS: A database of 767,464 results from 12,721 cases affected with 60 conditions was used to build multivariate pattern recognition software that generates tools integrating multiple clinically significant results into a single score. This score is determined by the overlap between normal and disease ranges, penetration within the disease range, differences between conditions, and weighted correction factors.
RESULTS: Ninety tools target either a single condition or the differential diagnosis between multiple conditions. Scores are expressed as the percentile rank among all cases with the same condition and are compared to interpretation guidelines. Retrospe...
