Os autores apresentam o caso clínico de um homem de 39 anos de idade com antecedentes de pancreatite crónica, que apresenta um quadro de hemorragia digestiva alta recorrente, com repercussão hemodinâmica, endoscopias altas sucessivas sem alterações, e cujos exames imagiológicos revelam presença
de mal-formação vascular do tronco celíaco. Na sequência de mais um episódio de hemorragia digestiva alta com franca repercussão hemodinâmica, é internado no Serviço de Medicina,realizando arteriografia selectiva que mostrou a presença de pseudo-aneurisma da artéria gastroduodenal. Após a embolização, verificou-se uma progressiva e mantida melhoria da sua situação clínica. Descrevem os autores um quadro de hemorragia
digestiva alta recorrente por malformação arterial associada à pancreatite crónica.
OBJECTIVE:
To evaluate the influence of the local prenatal surveillance of twin pregnancies in the obstetrical results.
METHODS:
A prospective cohort study of multiple pregnancies delivered over a period of 16 years in a tertiary centre was conducted. In this study 861 twin pregnancies were included. They were compared for obstetric complications, gestational age at delivery, mode of delivery and birthweight, according to the place of the surveillance.
RESULTS:
Of the 861 cases examined, the following obstetric complications were significantly different: metrorrhagia (p = 0.039), infections (p < 0.001), HELLP (p = 0.007), PROMPT (p < 0.001) and fetal death (p = 0.024). The mode of delivery was similar but occurred mostly ≤32 weeks (p < 0.001), the birthweight was mostly <2000 g and occurred more NICU admission (p < 0.001) when sur...
PURPOSE:
To evaluate the obstetric and perinatal outcomes evolution of triplet pregnancies.
METHODS:
A prospective observational study was conducted in triplet pregnancies delivered over 16 years in a tertiary obstetric center with differentiated perinatal support. Evaluation of demographic factors, obstetric complications, gestational age at delivery, mode of delivery, birth weight and immediate newborn outcome were done over a 16 years period. A global characterization of the sample was performed considering the listed parameters. Variables were categorized in three groups according to year of occurrence: 1996-2000, 2001-2006, 2007-2011, and all parameters were compared.
RESULTS:
Of the 33 triplets included, 72.7% resulted from induced pregnancies. All except one patient received prenatal corticosteroids and five received tocoly...
Efectuou-se o estudo da eliminação parasitária em quatro grupos de ovelhas em pastoreio [raça pura Merino Branco e cruzamentos rotativos com as raças Serra da Estrela (SE), Île de France (IF) e Romanov (RO)], com o objectivo de determinar o tipo e o grau de parasitismo presentes.
Durante o período de Fevereiro a Maio de 2002 realizaram-se quinzenalmente colheitas directas de fezes e as respectivas análises coprológicas qualitativas e quantitativas.
Verificou-se a presença de estrongilídeos gastrintestinais (ovos), e pulmonares (larvas de 1º estadio - L1), assim como ovos de Strongyloides sp., Moniezia sp., Taenidae e de oocistos de Eimeria sp.A média de eliminação de ovos de estrongilídeos gastrintestinais, para a raça pura, variou entre ligeira e média, enquanto que, para os cruzamentos, considerados variou entre ligeira, média e ...
Os AA apresentam um caso clínico de sarcoma indiferenciado do fígado no adulto com metástases pulmonares, cardíacas e com recidiva local hepática. Salienta-se a contribuição dos exames complementares de diagnóstico, com especial relevo para a ecocardiografia no diagnóstico precoce de metástases intracardiacas. Não encontrámos qualquer outro caso descrito na literatura portuguesa.
A case of undifferentiated sarcoma of the liver with heart, lung and liver metastases, is reported. We emphasised the role of ultrasound for the early diagnosis of cardiac metastases. As far as we know there is no other report on this tumour in portuguese literature.
INTRODUCTION: The ProACS risk score is an early and simple risk stratification score developed for all-cause in-hospital mortality in acute coronary syndromes (ACS) from a Portuguese nationwide ACS registry. Our center only recently participated in the registry and was not included in the cohort used for developing the score. Our objective was to perform an external validation of this risk score for short- and long-term follow-up.
METHODS: Consecutive patients admitted to our center with ACS were included. Demographic and admission characteristics, as well as treatment and outcome data were collected. The ProACS risk score variables are age (≥72 years), systolic blood pressure (≤116 mmHg), Killip class (2/3 or 4) and ST-segment elevation. We calculated ProACS, Global Registry of Acute Coronary Events (GRACE) and Canada Acute Coronary ...
OBJECTIVE::
To compare patients without previously diagnosed cardiovascular risk factors) and patients with one or more risk factors admitted with acute coronary syndrome.
METHODS::
This was a retrospective analysis of patients admitted with first episode of acute coronary syndrome without previous heart disease, who were included in a national acute coronary syndrome registry. The patients were divided according to the number of risk factors, as follows: 0 risk factor (G0), 1 or 2 risk factors (G1 - 2) and 3 or more risk factors (G ≥ 3). Comparative analysis was performed between the three groups, and independent predictors of cardiac arrest and death were studied.
RESULTS::
A total of 5,518 patients were studied, of which 72.2% were male and the mean age was 64 ± 14 years. G0 had a greater incidence of ST-segment elevation myoca...
INTRODUCTION:
There are barriers to proper implementation of risk stratification scores in patients with acute coronary syndromes (ACS), including their complexity. Our objective was to develop a simple score for risk stratification of all-cause in-hospital mortality in a population of patients with ACS.
METHODS:
The score was developed from a nationwide ACS registry. The development and internal validation cohorts were obtained from the first 31829 patients, randomly separated (60% and 40%, respectively). The external validation cohort consisted of the last 8586 patients included in the registry. This cohort is significantly different from the other cohorts in terms of baseline characteristics, treatment and mortality. Multivariate logistic regression analysis was used to select four variables with the highest predictive potential....
