- Colestase Intra-Hepática da Gravidez Casuística da Maternidade do Hospital Dona EstefâniaPublication . Correia, A; Olival, V; Pereira, N; Ravara Bello, A; Caetano, M; Mahomed, FIntrodução: A CIHG é uma patologia que surge habitualmente na 2ª metade da gestação e tem carácter recorrente. Objectivo: Determinar a incidência da patologia, o outcome obstétrico e fetal das grávidas com diagnóstico de CIHG. Métodos: Estudo retrospectivo, de Janeiro/2004 a Outubro/2010. Variáveis estudadas: referentes à grávida (idade, antecedentes obstétricos), gravidez (idade gestacional ao diagnóstico, conduta clínica) e parto (incluindo complicações intra-parto), bem como complicações maternas/fetais pós-parto. Resultados: 57 grávidas (incidência 0,41% - 57/14053), com idade média 31,5±5,8 anos, 56,1% nulíparas e 36% com antecedentes pessoais de CIHG. A sintomatologia surgiu em média às 33,8±3,1 semanas (S). Em 55,9% procedeu-se a internamento imediato (IG 35±2,7S), 44,1% foram vigiadas em ambulatório (IG 32,1±3S), em média durante 3,7±1,9S. 57,9% necessitaram de terapêutica médica. Em 65% procedeu-se a indução do trabalho de parto, na maioria dos casos pela idade gestacional (≥37S); 17,5% iniciaram trabalho de parto espontâneo (70% pré-termo). Cesariana em 38,6%, das quais 72,7% em âmbito de urgência. 22,2% de casos de CTG intra-parto não tranquilizador e em 15,8%,líquido amniótico meconial. A idade gestacional média ao nascimento foi 36,2±2,2S; 38,6% RN prematuros (2/3 iatrogénicos), tendo-se verificado 1 caso de hemorragia pós-parto, 3 de febre puerperal e 1 de asfixia neonatal grave. Discussão: Patologia de baixa incidência, recorrente, atingindo frequentemente grávidas de grupo etário superior. Associa-se a marcada iatrogenia, prematuridade, risco de distócia e sofrimento fetal intra-parto. Estes dados estão de acordo com a literatura.
- Confined Placental Mosaicism in Chorionic Vilus Sampling - Case ReportPublication . Olival, V; Caetano, P; Bernardo, A; Correia, H; Caetano, M; Mira, RObjectives: Chorionic Vilus Sampling (CVS) has several advantages over amniocentesis: it may be performed at an earlier gestational age, the results are quicker to obtain and there’s a lower miscarriage risk – 1%. However, the higher prevalence of discrepant fetal and vilus sampling material’s karyotype findings is a disadvantage of this technique – 0.5%. This is caused, amongst other causes, by placental mosaicism which consists of two genetically different cell lines. There are three types of placental mosaicism according to the abnormal cell line location: Type I – in the cytotrophoblast; Type II – in the vilus’ stroma; Type III – in both the above locations. Material and Methods: We present a case report about a 36-year-old pregnant woman going through our Department’s 1st trimester combined screening program; a CVS was performed, which showed Confined Placental Mosaicism (CPM). Results and Conclusion: Although the pregnant woman was in the low-risk group for aneuploidy, the patient wanted the cytogenetic study to be performed in order to reduce maternal anxiety. CVS was performed at the gestational age of 12 weeks + 5 days and the karyotype was 47XY+2/46XY. For the correct interpretation of this data an amniocentesis was performed at the gestational age of 15 weeks + 6 days, which showed a 46XY karyotype. We therefore conclude that the cytogenetic analysis of the CVS was the result of a CPM. A careful follow-up including fetal echocardiogram and seriated ultrasonographic monitoring was used to safely exclude malformations and fetal growth restriction. We verified no occurences throughout pregnancy, delivery and perinatal period. CVS practice was recently implemented in our country and has many advantages over amniocentesis. Besides the fact that an earlier gestational age usually means less affective bonding to the fetus and therefore makes medical termination of pregnancy somewhat less difficult, one should consider specific situations like the one reported in which CPM may be diagnosed. This condition is associated with increased risk of fetal growth restriction, so the clinician should be aware of the need for a more careful follow-up, since perinatal complications, which should be anticipated and treated, can be expected in 16-21% of these cases.
- Myomectomy in Early Pregnancy - A Case ReportPublication . Santos, L; Vicente, L; Nunes, MJ; Nery, I; Caetano, M; Assunção, NUterine leiomyomas are by far the most common benign tumours of the female genital tract. The true incidence of leiomyomas during pregnancy is, however, unknown. Although leiomyomas usually remain asymptomatic during pregnancy, they may complicate its course. The management of leiomyoma during pregnancy is medical, but, in rare circumstances, surgical intervention and myomectomy may be required. A case of myomectomy in early pregnancy is described.
- Ocular Toxoplasmosis Reactivation During Pregnancy – A Case ReportPublication . Olival, V; Ravara Bello, A; Cabugueira, A; Dias, I; Caetano, M; Nunes, MJ; Nery, I; Mira, RIntroduction: Toxoplasmosis is caused by Toxoplasma gondii and may be acquired from food or water contaminated with cat feces or by vertical transmission. Severe fetal complications can overcome during pregnancy. There are also rare case-reports of congenital toxoplasmosis from previously immunized pregnant women; usually these women being had prior retinal toxoplasmic lesions. Immunosuppresion is one of the risk factors which accounts for some of these cases. Case report: 30 year-old pregnant woman, OI 2002, brazilian, previously healthy, admitted in Ophtalmology Department because of sudden left eye amaurosis in June, 2010. The fundoscopy revealed retinal scars suggesting previous infections; she was treated with corticoids and spiramycin for ocular toxoplasmosis reactivation. Previous serum analysis (2008) showed immunity to T. Gondii, but in July the IgM was negative and high levels of specific IgG were found (1227UI/mL). The serologic findings were later confirmed by a more accurate laboratory technique which found the IgM to be also positive. An amniocentesis was performed and it was negative for fetal transmission. Clinical and ultrasound follow-up throughout the rest of the gestational period was normal; daily spiramycin intake was maintained. An uneventful term delivery was performed. Neither the newborn’s serum analysis nor the histopathological study of the placenta were positive for congenital infection. Conclusion: Toxoplasmosis reactivation in pregnant women without immunosuppression is rare but is more likely to occur if previous post-infectious retinal scars are present. T. gondii infection is endemic in Brazil, so the geographical origin is important. If risk factors are present, fundoscopy should be performed every three months during pregnancy and one should always be aware of any visual symptoms. If you suspect reactivation, start medical prophylaxis for fetal transmission, perform amniocentesis and regular ultrasound follow-up.
- Ruptura Uterina - A Propósito de 2 Casos ClínicosPublication . Olival, V; Condeço, R; Vaz, D; Sousa, F; Nunes, MJ; Leitão, C; Ferreira, C; Caetano, M; Dias, I; Coelho, M; Mira, RIntrodução: A ruptura uterina leva a consequências graves materno-fetais. A maioria dos casos ocorre em grávidas com cesarianas anteriores ou incisões uterinas prévias como miomectomia, raramente ocorrendo em úteros sem cicatrizes. Um dos principais factores correlacionado com o risco de ruptura é o tipo de incisão da histerotomia prévia: clássica (4-9%), em T (4-9%), vertical (1-7%); transversa (0,2-1,5%). Outros factores de risco são: ausência de parto vaginal anterior, indução do trabalho de parto, gravidez de termo, macrossomia fetal, multiparidade, sutura simples vs.dupla na histerorrafia prévia e intervalo curto entre gestações. 1-Caso clínico: Grávida, 28 anos, IO 2002 (cesariana em 2002 por apresentação pélvica; PTE em 2009), enviada ao nosso hospital para esclarecimento de anemia às 21 semanas. A gravidez decorreu normalmente; entrando espontaneamente em trabalho de parto em Agosto/2010. No período expulsivo a grávida referiu dor pélvica súbita com irradiação lombar. Teve um parto eutócico com distócia de ombros leve. Duas horas após, a puérpera apresentava-se inquieta, pálida e hipotensa comHb de 7,3g/dl. Decidiu-se laparotomia, constatando-se ruptura uterina no segmento inferior com prolongamento para a parede posterior, realizando-se histerorrafia.Pós-operatório sem intercorrências. 2-Caso clínico: Grávida, 41 anos, IO 0000, antecedentes pessoais de miomectomia por laparoscopia sem entrada na cavidade em 2008 e 2009, enviada ao nosso hospital para Consulta de DPN. Foi internada às 17+3 semanas para IMG por alteração do cariótipo fetal (Trissomia 21). Iniciou-se o protocolo para IMG aplicando-se unicamente 100 microg de misoprostol;24 horas após, a doente encontrava-se agitada e hipotensa, com episódio de lipotímia. Realizou-se laparotomia com visualização de ruptura uterina fúndica, corrigida com histerorrafia sem intercorrências Conclusão: Dada amorbi/mortalidade materno-fetal associada à ruptura uterina é fundamental reconhecer os factores de risco e os sintomas associados a esta, tal como o seu diagnóstico atempado e resolução imediata, minimizando os riscos materno-fetais.
