  • Biópsia Hepática Percutânea em Doentes Oncológicos - a Propósito de um Caso Clínico
    Publication . Lucas, R; Amaral, P; Ladeira, C; Lourenço, J; Vieira, L; Oliveira Martins, F; Marques, A
    A biópsia hepática percutânea guiada por imagem é uma ferramenta útil que permite obter um diagnóstico histológico fiável sem necessidade de intervenção cirúrgica. Não é contudo um procedimento isento de complicações. No caso particular dos doentes com contexto oncológico conhecido o diagnóstico e estadiamento preciso é indispensável para seleção da terapêutica adequada. Nestes doentes deve dar-se preferência à caracterização imagiológica, contudo em casos onde permanecem dúvidas pode recorrer-se à biópsia. Neste artigo apresentamos um caso de sementeira tumoral no trajecto da agulha de biópsia hepática percutânea, num doente com diagnóstico recente de neoplasia intra-epitelial do cólon, com múltiplas lesões hepáticas e um nódulo pulmonar, detectados na avaliação imagiológica de estadiamento inicial.

  • HELLP Syndrome a Severe Form of Preeclampsia: a Comparative Study of Clinical and Laboratorial Parameters
    Publication . Campos, A; Gonçalves, A; Massa, AC; Amaral, P; Silva, P; Aguilar, S
    The objective of this study was to compare clinical, laboratorial, maternal and perinatal results between HELLP Syndrome and severe Preeclampsia. An observational study comparing women with HELLP Syndrome (n=71) to women with severe preeclampsia (n=253) was done. The authors analyzed the early course of the pathologies and the outcomes in both groups. HELLP syndrome occurred in 28% of all the cases and was more frequent at gestational age before 32 weeks (n=39 – 55%) than severe preeclampsia (n=108 - 42%), with more newborns weighting less than 1500g (27 – 38.6% vs 65 – 25.6%; p=0.036). Thrombocytopenia below 100 000/μL (aOR, 2.14; 95% CI, 1.49 – 3.06) and LDH>1 000 UI/L (aOR: 5.17; 95% CI 2.19 – 12.16) were risk factors for HELLP. Maternal morbidity (eclampsia, abruptio placentae, and acute renal failure) was similar in both cohorts; eight stillbirths (6 in severe preeclampsia and 2 in HELLP Syndrome) occurred. There were no maternal deaths. In conclusion, in this study the authors confirmed that HELLP Syndrome is a severe form of preeclampsia with an earlier presentation in pregnancy, worst laboratorial findings and more prematurity rates.

  • Synchronous Endometrioid Endometrial and Ovarian Cancer in a 34-Year-Old Woman
    Publication . Amaral, P; Silva, A; Lacerda, A; Barros, C
    Ovarian cancer is the leading cause of death from gynaecological malignancy in developed countries. Synchronous endometrioid endometrial and ovarian cancer in patients appears with different clinical characteristics compared to patients with isolated endometrial cancer. A 34-year-old woman with lower abdominal pain of 1 year duration presented at the emergency department. On gynaecological examination, she had a left and midline pelvic mass. A transvaginal ultrasound showed it to be a complex hypervascularised mass, with cystic and solid components on left adnexal region. Ectopic pregnancy and pelvic inflammatory disease were excluded. Serum levels of tumour marker CA125 and ROMA were increased. The MR showed a complex mass, suggestive of primary fallopian tube or ovarian tumour. The patient underwent a total abdominal hysterectomy, bilateral salpingo-oophorectomy, pelvic and para-aortic lymph node dissection and subcolonic omentectomy. Histopathology revealed a synchronous endometrioid endometrial and ovarian cancer.
