- In Situ Breakage of Implanon® - Two Cases of a Rare OccurrencePublication . Torres, R; Mendes, N; Machado, AI; Marques, CBACKGROUND: 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.
- Inferior Vena Cava Filter Placement During Pregnancy: an Adjuvant Option When Medical Therapy FailsPublication . Valadares, S; Serrano, F; Torres, R; Borges, AThe 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 option as prophylaxis for pulmonary embolism during pregnancy.
- Influência da Nacionalidade nos Resultados Obstétricos e Perinatais numa Coorte de Grávidas com Diabetes GestacionalPublication . Torres, R; Carrilho, B; Aleixo, F; Rocha, T; Amaral, NIntrodução: 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-parto. Todas as análises estatísticas foram efectuadas em SPSS 17ª Edição. Resultados: No grupo 2 assistiu-se a um controlo metabólico mais difícil, maior percentagem de hidrâmnios e macrossomia fetal. Conclusões: O controlo metabólico na Diabetes gestacional é diferente em grávidas provenientes de países diferentes. Os hábitos alimentares e religiosos que condicionam a educação nutricional durante a gravidez, associados à barreira linguística podem ser responsáveis pelas diferenças encontradas. Uma maior compreensão dos factores multiculturais com posterior adequação dos cuidados poderá permitir melhores resultados obstétricos e perinatais.
- Oncocitoma Renal na Gravidez. Uma Forma Invulgar de Hipertensão SecundáriaPublication . Torres, R; Borges, A; Campos, AIntrodução: 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 renal-oncocitoma. Conclusão: O comportamento clínico do oncocitoma renal permanece mal caracterizado durante a gravidez, podendo associar-se, apesar do seu comportamento teoricamente benigno, a um desfecho materno e fetal adverso. É fundamental excluir uma possível causa secundária nos quadros hipertensivos de difícil controlo.
- Rotura Uterina em Mulheres com Cesariana Anterior em Prova de Trabalho de PartoPublication . Mendes, N; Torres, R; Campos, A; Serrano, FUterine 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.
- Sépsis MaternaPublication . Torres, R; Mendes, N; Valadares, S; Serrano, FInfections 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 relevance of pregnancy surveillance by a multidisciplinary team. The treatment of sepsis is time-critical and requires early diagnosis, aggressive resuscitation, antibiotic administration and source control.
- Usefulness of TNFR1 As Biomarker of Intracranial Aneurysm in Patients with Spontaneous Subarachnoid HemorrhagePublication . Torres, R; Mancha, F; Bustamante, A; Canhao, P; Fragata, I; Montaner, JAim: To determine the utility of TNF-α receptor (TNFR1) as a biomarker for the presence of aneurysms in patients with acute subarachnoid hemorrhage (SAH). Patient & methods: This is a prospective study in patients with acute spontaneous SAH. Arterial blood from catheter near aneurysm and peripheral venous blood samples are collected. TNFR1 levels were analyzed in patients with and without aneurysm. Results: 80 patients were included, 58 were analyzed. 41 patients (70.7%) had an aneurysm. Venous TNFR1 levels >1658 pg/ml had 46.3% sensitivity and 94.1% specificity for aneurysms presence. TNFR1 >1658 pg/ml was also an independent predictor for its presence (odds ratio = 12.03 [1.13-128.16]; p = 0.039). Conclusion: High levels of TNFR1 in peripheral venous blood are associated with the presence of aneurysm in patients with acute SAH.
