- Corionicidade e complicações perinatais na gravidez gemelar: casuística de 10 anosPublication . Manso, P; Vaz, A; Taborda, A; Santos-Silva, IOVERVIEW AND AIMS: Multiple pregnancy accounts for about 3% of all pregnancies. The monochorionic pregnancy presents a relatively constant incidence (1:250 pregnancies) unlike the dichorionic, which is influenced by race, heredity, maternal age, parity and medically assisted procreation. The purpose of this work was to evaluate the impact of chorionicity on perinatal morbidity of twin pregnancy. POPULATION AND METHODS: Retrospective, longitudinal, descriptive and analytical study of women with twin pregnancy whose birth occurred in our maternity hospital since January/1999 until December/2008. Inclusion criteria: monochorionic and dichorionic twin pregnancies confirmed by ultrasound. Exclusion criteria: monochorionic monoamniotic gestation. Demographic data, delivery variables and perinatal morbidity and mortality were studied. Data were evaluated using the χ2 test (qualitative variables), t-Student (continuous quantitative variables) and Mann-Whitney test (quantitative discrete variables). RESULTS: We studied 504 pregnancies (356 dichorionic diamniotic and 148 monochorionic diamniotic). The monochorionic pregnancy had a higher incidence of threatened preterm labor (43,9% vs 31,5%, p<0,05), of oligohydramnios/hydramnios (9,8% vs 3,3%, p<0,001), discordant fetal growth (26,8% vs 14,8%, p<0,001) and intrauterine growth restriction (7,4% vs 3,7%, p<0,05). Prematurity was more common in the monochorionic group (p<0,001). The cesarean delivery rate was higher in monochorionic pregnancy (58,8% vs 50,3%, p<0,05) and the average weight of newborns was lower in monochorionic pregnancies (1983g vs 2233g, p<0,001). Newborns in the monochorionic group had higher incidence of hyaline membrane disease (5,8% vs 2,8%, p<0,05) and intraventricular haemorrhage (2,1% vs 0,4%, p<0,05). The perinatal mortality was higher in the monochorionic group (7,8% vs 1,8%, p<0,001). CONCLUSIONS: As the morbidity and mortality associated with monochorionic pregnancies are higher, it is essential to perform an early detection of chorionicity by ultrasound (11-13 weeks) in order to place differentiated prenatal and appropriate peripartum surveillance.
- Crescimento discordante precoce numa gravidez gemelar monocoriónicaPublication . Sousa, S; Passarinho, R; Alves, M; Taborda, A; Santos-Silva, IIntroduction: Abnormal growth, including discordant growth and intrauterine growth restriction (IUGR), occurs frequently in twin pregnancies and has been associated with increased risk of perinatal morbidity and mortality. Typically this occurs in the second or third trimester. Discordant growth in monochorionic twin pregnancies is probably related with the complications of a shared placenta. It is not clear whether there is increased risk of perinatal morbidity in both discordant twins or only in those with low birth weight. Case report: A 21 year old primigravida with a spontaneous monochorionic twin pregnancy was seen to have a crown-rump length discordance at 8 weeks of gestation (one fetus with 6mm and the other with 12 mm). All routine tests were normal. No major congenital or karyotype abnormalities or evidence of twin to twin transfusion syndrome (TTTS) were detected during follow up examinations. This discrepancy persisted until birth: fetus A was in the 25th percentile while fetus B below the 5th percentile. Umbilical artery flow in both twins remained normal. At 34 weeks, preeclampsia developed and labor induction was performed. The twins had a birth weight of 2195 g and 1415 g (35,5% discrepancy), and an Apgar score of 7 and 10 at 5th minute, respectively. They remain in the neonatal intensive care unit for 29 days, with the larger twin having more complications: transient tachypnea of the newborn, pneumothorax and hyperbilirubinemia. At two years old, they both had a normal development. Discussion: In monochorionic twins with a normal karyotype and no evidence of TTTS, the causes of discordant growth are not always clear. In this case, the occurrence of discordant growth and IUGR did not lead to more complications in the smaller twin.
- Crise hipercalcémia secundária a hiperparatiroidismo primário durante a gravidezPublication . Branco, MR; Rodrigues, CT; Campos, A; Figueiredo, A; Coucelo, J; Magalhães, C; Santos-Silva, I; Taborda, A; Almeida, MCPrimary hyperparathyroidism is a rare occurrence in pregnancy with significant risks to the mother and the foetus, witch is related to the level of serum calcium. A 41-year-old women, gravida 2, para 1, presented at 22 weeks gestation with nausea, vomiting and mild cognitive dysfunction associated with hypercalcemic crisis. The hypercalcemia was observed to be related to parathyroid hyperplasia that was surgically removed. Complete resolution of her symptomatology and hypercalcemia occurred postoperatively. The pregnancy was complicated with transient hypertension. A small for gestational age healthy male infant was delivered at term with no neonatal complications related with this pathology.
- Epidemiologia da gestação múltipla: casuística de 15 anosPublication . Rodrigues, CT; Branco, MR; Ferreira, ID; Nordeste, A; Fonseca, M; Taborda, A; Santos-Silva, I; Almeida, MCBetween January of 1987 and December of 2001 were born 1243 twins related to 609 multiple pregnancies, in Maternidade Bissaya-Barreto. Data were grouped in periods of three years and several parameters were studied. The rate of multiple gestation has increased probably due to the contribution of the assisted conception techniques, and to the increase of the number of multiple fetal pregnancies (two or more) and to the increase of the mother age. These more frequent obstetric problems were preterm birth, gestational hypertension and abnormal sonographic data of fetal growth. The average age of delivery was 34 weeks and the birth weight has decreased. The most important factors for neonatal morbidity were hyaline membranous disease, intraventricular haemorrhage and the twin-twin transfusion syndrome. The neonatal mortality decreased in the last studied period.

- Neonatal meningitis associated with osteomyelitis and epidural empyema.Publication . Vale, B; Morais, S; Resende, C; Taborda, ANeonatal meningitis is a serious disease with significant mortality and morbidity. Its signs and symptoms are subtle, non-specific, atypical or absent. Cephalohaematoma is frequent in newborns and complications are uncommon, including local infection after haematogenous spread in the setting of bacteraemia or meningitis with a possibility of osteomyelitis, epidural abscess and subdural empyema. We report the case of a late preterm newborn, with an unremarkable pregnancy, born by vacuum-assisted vaginal delivery that presented in the fifth day of life with irritability, fever and grunting. Cerebrospinal fluid and blood cultures were positive for Escherichia coli. The patient had neurological deterioration despite adequate antibiotic therapy and brain MRI showed a right parietal epidural empyema, subcutaneous abscess, osteomyelitis and supratentorial hydrocephalus. The culture of the cephalohaematoma's abscess material was positive for E coli. Antibiotic therapy was continued for 8 weeks. The child, now 2 years old, has spastic tetraparesis with global development delay.
- Severe intracranial haemorrhage in neonatal alloimmune thrombocytopeniaPublication . Silva, F; Morais, S; Sevivas, T; Veiga, R; Salvado, R; Taborda, ANeonatal alloimmune thrombocytopenia is a rare (1/1000-5000 births) life-threatening disorder, caused by fetomaternal incompatibility for a fetal human platelet alloantigen inherited from the father, with production of maternal alloantibodies against fetal platelets, leading to severe thrombocytopenia and potential bleeding. Intracranial haemorrhage is the most feared complication. This report presents the case of a term newborn infant, born from caesarean section after a normal pregnancy, presenting signs of skin bleeding with different ages. Obstetric history included a previous spontaneous abortion after amniocentesis. Severe thrombocytopenia (4×10(9)/l platelets) was found and brain ultrasound showed multiple intracranial haemorrhages. Human platelet antigen (HPA) phenotyping showed maternal negative HPA-1a and paternal positive HPA-1a platelets. Strongly positive anti-HPA-1a and weakly positive anti-human leukocyte antigen class I alloantibodies were found in the mother. Multiple platelet transfusions, intravenous immunoglobulin and corticosteroid were given but favourable response was accomplished only after a compatible platelet transfusion. Brain MRI showed multiple subacute and chronic haemorrhages.
