Identical triplets with infantile autism and the fragile-X syndrome.

In a continuing twin study of autism in Scandinavia and Finland, moderately mentally retarded triplets fulfilling Rutter's criteria for infantile autism were reported. Judging by physical appearance the triplets were identical. Behaviourally they were extremely similar though one was intellectually slightly better than the other two. All three showed the physical stigmata characteristic of the fragile-X syndrome, in spite of their overall appearance being non-conspicuous. The triplets had between 8 and 12 per cent of fragile-X positive cells and showed a distinct pattern of urinary excretion of substances yielding absorbency at 280 nM. Their mother and sister also had a high count of fragile-X positive cells.

Conservative management of triplet pregnancy after delivery of one foetus.

This paper intends to demonstrate that the conservative management of triplet pregnancy after delivery of one foetus is a feasible and reasonable approach. Three cases of triplet pregnancy with successful conservative management after miscarriage of one foetus, are presented and compared with cases in the literature. The route of delivery, as well as the role of tocolysis, cerclage, prophylactic antibiotic therapy and corticosteroids are discussed. Guidelines for conservative treatment are proposed. The deliveries of our three pregnancies were delayed by 63, 44 and 22 days respectively. Foetal and neonatal evolution are normal in five of the remaining foetuses. Only one intrauterine death is observed. No maternal complications with sequelae are reported. After abortion of the first triplet, contractions often persist and the birth of the two remaining foetuses may be unavoidable. Nevertheless, in our experience, confirmed by some reports in the literature, prolongation of the pregnancy after expulsion of the first foetus is possible. It can be achieved by cervical cerclage associated with tocolytic and antibiotic therapy. This management is not associated with significantly increased foetal-maternal morbidity.

The odds of delivering one, two or three extremely low birth weight (< 1000 g) triplet infants: a study of 3288 sets.

The odds of an individual triplet pregnancy to end with neonates weighing < 1000 g (extremely low birth weight [ELBW]) are unknown. We analyzed a nationwide perinatal database collected by Matria Healthcare, Inc. (Marietta, GA) to select from 3288 triplets those weighing 500-1000 g, delivered during the period 1988-2000 in the United States. We counted the number of sets with one, two, and three ELBW neonates and compared the incidence of ELBW infants between the subsets of nulliparas and multiparas. The odds of delivering at least one ELBW infant was significantly higher among nulliparas (1:8) than among multiparas (1:14), Odds Ratio (OR) 1.9, 95% Confidence Interval (CI) 1.9, 2.5. The odds of having at least two ELBW sibs in nulliparas (1:16) is twice higher than in multiparas (1:31), OR 2.0, 95% CI 1.3, 2.9. Nulliparas and multiparas had similar odds of delivering three ELBW infants (1:29 versus 1:40, OR 1.3, 95% CI 0.9, 2.1). Nulliparas are at significantly increased risk of delivering one or two ELBW triplets. This observation is no less than alarming and highlighted by the exceptionally high risk of major neurological deficits reported among ELBW infants.

Agenesis of the corpus callosum: female monozygotic triplets. Case report.

A case of identical (monozygotic) triplets, two of whom have agenesis of the corpus callosum, is presented. Prenatal ultrasonography and magnetic resonance imaging revealed two of the triplets to have agenesis of the corpus callosum and the third triplet to have an intact corpus callosum. No such case has been reported in the literature. Theories of the etiology and pathogenesis of corpus callosum agenesis are discussed. In this case, unequal X-inactivation as related to the twinning process is implicated as the cause of the agenesis.

Triplets and quadruplets born in Victoria between 1982 and 1990. The impact of IVF and GIFT on rising birthrates.

OBJECTIVES: To examine the perinatal characteristics of all higher order multiple births (133 sets of triplets and six sets of quadruplets) in the State of Victoria between 1982 and 1990. To compare the rising higher order multiple birth rates in Victoria with those in the other States of Australia, and to assess the impact of in-vitro fertilisation (IVF) and gamete intrafallopian transfer (GIFT) on these rising birth rates. DESIGN: Retrospective review of all higher order multiple births registered in Victoria and other States of Australia between 1982 and 1990, and in particular those resulting from IVF and GIFT. DATA SOURCES: Victorian Perinatal Data Collection Unit, Australian Bureau of Statistics, National Perinatal Statistics Unit, data from Victorian IVF and GIFT units. MAIN OUTCOME MEASURES: Higher order multiple birth rates and perinatal mortality rates. RESULTS: The higher order multiple birth rates in Victoria rose from 3.5 per 10,000 in 1982 to 10.9 per 10,000 in 1990. The average perinatal mortality rates for the Victorian triplets and quadruplets born during this period were 10.8% and 25.0%, respectively. The rates of caesarean section were 70% and 83%; the proportions of deliveries in level III hospitals, 75% and 100%; and the mean maternal lengths of stay in hospital, 32 and 57 days, respectively. Endotracheal intubation was performed at birth in 18.5% of all infants. The proportions of triplet and quadruplet pregnancies in Victoria owing to IVF and GIFT rose during this period, reaching a peak of 42% in 1990. In the other States, the birth rates for higher order multiples increased at 1.8 times the rate observed for Victoria, with IVF and GIFT contributing to an estimated 43% of these conceptions between 1985 and 1989. CONCLUSION: Restrictions on the numbers of embryos/oocytes transferred during IVF and GIFT should reduce the frequency of higher order multiple births.

Contribution of assisted reproductive technology and ovulation-inducing drugs to triplet and higher-order multiple births--United States, 1980-1997.

In the United States, pregnancies associated with assisted reproductive technology (ART) or ovulation-inducing drugs are more likely to result in multiple births than spontaneously conceived pregnancies (1). In addition, triplet and higher-order multiple births are at greater risk than singleton births to be preterm (< or = 37 completed weeks' gestation), low birthweight (LBW) (i.e., < or = 2500 g), or very low birthweight (i.e., < 1500 g), resulting in higher infant morbidity and mortality (2). Because preterm and LBW infants often require costly neonatal care and long-term developmental follow-up, the continuing increase in triplet and higher-order multiple births causes concern among health-care providers and policymakers (3). This report provides estimates of the contribution of ART and ovulation-inducing drugs to these birth outcomes for 1996 and 1997, and summarizes trends during 1980-1997, which indicate that the ratio of triplet and higher-order multiple births has more than quadrupled and that a large proportion of this increase can be attributed to ART or the use of ovulation-inducing drugs.

Monoamniotic twins in a triplet gestation with favorable outcome.

BACKGROUND: Monoamniotic twins in a triplet gestation is a rare combination. Each condition is separately associated with significant perinatal morbidity and mortality. There are no data about the outcome and management of such gestations. CASE: We report a case of monoamniotic twins in a spontaneous dichorionic triplet gestation with a favorable outcome. Transvaginal ultrasound examination at nine weeks confirmed the diagnosis. Close follow-up was established that included continuous fetal monitoring after 30 weeks. At 35 weeks and after confirming fetal lung maturity, elective cesarean delivery was performed resulting in three liveborn female infants. CONCLUSION: Favorable outcome of such a rare coexistence of monoamniotic twins in a triplet gestation is possible. Vigilant fetal monitoring and timed delivery remain the mainstays of management.

Pregnancy prolongation in triplet pregnancies. Oral vs. continuous subcutaneous terbutaline.

OBJECTIVE: To assess gestational gain in triplet pregnancies treated with oral terbutaline followed by treatment with continuous subcutaneous terbutaline. STUDY DESIGN: From a database of patients who received perinatal home care services, we identified women with triplet gestations first receiving daily oral terbutaline following an episode of threatened preterm labor who subsequently received continuous subcutaneous terbutaline infusion after recurrence of preterm contractions. The primary outcome studied was gestational gain with oral terbutaline vs. gestational gain with continuous subcutaneous terbutaline infusion. RESULTS: One hundred four women were studied. The mean gestational age at enrollment was 22.0 +/- 2.7 weeks. Significantly more gestational gain was achieved during subcutaneous tocolytic treatment than during oral treatment (mean 5.4 +/- 3.4 vs. 2.8 +/- 2.2 weeks, P < .001). Twenty-nine percent of desired prolongation was achieved with oral terbutaline, while 71% of desired prolongation was achieved with subcutaneous terbutaline infusion (P < .001). The mean gestational age at delivery was 33.2 +/- 2.2 weeks. CONCLUSION: Gestational gain was greater in triplet pregnancies during treatment with continuous subcutaneous terbutaline infusion than with oral terbutaline.

Defining the high-risk nature of triplet pregnancies.

Triplet pregnancies are by nature rare. Assisted reproductive technologies have multiplied their rate of occurrence in the last two decades. Whether spontaneous or induced, triplet pregnancies present obstetric and neonatal-and then often lifelong-medical problems severalfold more often than singletons, or even twins. The major cause of problems for triplet gestations stems from preterm delivery and low birth weight.

[Triplet pregnancy complicated by intrauterine death of two fetuses--case report].

INTRODUCTION: Multiple pregnancy still constitutes a difficult therapeutic problem in perinatology. The incidence of this phenomenon describes Hellin's formula: the number of twin pregnancy is 1/n, triplet--1/n 2 etc. Among complications observed in multiple pregnancy intrauterine death of one or more foetuses is not rare. Due to progressive disturbances in haemostasis the risk for a mother and remaining live foetus increases with gestation. The aim of this paper was to present a case report of triplet pregnancy complicated by an intrauterine death of two foetuses. REPORT: 33 years old patient was diagnosed by ultrasound in the 19th week of her second gestation (1 child) a triplet pregnancy. Three live foetuses were seen then with biometry of about 14/15 gestational week There was one joint placenta on the back uterine wall and two children were sharing an amniotic sac. On the consecutive ultrasound examination the three foetuses were alive, but only one had a biometry for 21st week, two--were slowing down having measurements adequate for 19/20th week. After four weeks on usg the death of two siblings was confirmed (age 19/20 gestational week). One remaining live foetus was according to usg 24 weeks old. The patient was transferred to the II Dept. Even though no disturbances in coagulation were observed, low molecule heparin prophylaxis was introduced. During hospital stay a gestational diabetes was diagnosed well corrected by diet only. Coagulation parameters as well as infection indexes were regularly monitored. The foetal well-being was established by non-stress test, biophysical profile and Doppler vascular flows. After 39 days of hospitalisation an elevation of fibrin degradation products (FDP) was noted so the dosage of low molecule heparin was immediately increased to the therapeutic values. In spite of that FDP still were growing. It was decided to introduce a steroids treatment to accelerate the maturity of foetal lungs. In the 31st week according to usg, after PROM, the emergency caesarean section was performed. Daughter, breech presentation, weighting 1380 grams was born, with Apgar score 6-8-8. At the beginning artificial ventilation was necessary. After 11 days thanks to gradual improvement transfer from NICU to prematurity ward was possible. The postoperative period was uneventful and a mother was discharged home on the 7th day. CONCLUSION: Careful monitoring of a survived foetus as well as coagulation system has allowed to extend the duration of pregnancy for further 45 days and to deliver an infant capable to live.

Recombinant human erythropoietin in a triplet pregnancy: a case report.

BACKGROUND: Women carrying triplets are at greater risk for both anemia, due to the increased demands of the developingfetuses, and peripartum hemorrhage. Jehovah's witnesses are a unique obstetric population since women of this faith refuse blood transfusion. CASE: A Jehovah's Witness with a triplet pregnancy was successfully administered recombinant human erythropoietin (rHuEpo), 200 IU/kg 3 times per week subcutaneously, in order to correct her peripartum anemia. No side effects were observed during rHuEpo therapy, and the patient delivered healthy triplets. CONCLUSION: rHuEpo can be safely administered, with a beneficial effect in pregnancy, and seems to be an effective option in preventing transfusions as demonstrated in this case in a Jehovah's Witness.

Third-trimester fetal death in triplet pregnancies.

During the last decade, 89 sets of triplets were born in Denmark with a gestational age of more than 25 completed weeks. Fifteen pregnancies (16.9%) were complicated by fetal death in the third trimester, with a total of 17 intrauterine deaths. Six neonatal deaths occurred, leaving 22 survivors among these 15 patients. Four triplet gestations were diagnosed as twins until delivery. Eight women conceived spontaneously, two gestations followed assisted fertilization and embryo transfer, and five women had had various forms of ovulation stimulation. The mean maternal age was 27.8 years (range 17-38). Seven women were parous and eight wer nulliparous. Maternal complications included hydramnios (three), preeclampsia/hypertension (three), and anemia (nine). All women delivered preterm. Of the 11 gestations diagnosed as triplets, fetal death was diagnosed at 32.2 +/- 2.9 weeks (mean +/- SD) and delivery occurred at 32.6 +/- 3.0 weeks. Nine of 11 women had cesarean deliveries. Continuation of pregnancy after fetal death could be considered in only three subjects. In eight women, obstetric reasons required immediate delivery. Fetal death was associated with monochorionic or dichorionic placentation, and growth retardation was a frequent complication before fetal death. Anencephaly of one fetus, umbilical cord problems in two, and severe hydrops in two were the only obvious causes of fetal death. Fetal death should not be the sole indication for delivery. In cases with severe prematurity and a stable intrauterine situation, frequent assessments of fetal well-being are recommended, with prompt delivery when indicated.

Umbilical artery waveforms in triplet pregnancy.

Twenty patients with triplet pregnancies underwent continuous-wave Doppler ultrasound umbilical artery waveform studies as part of a multiple-pregnancy surveillance program. One or more infants was small for gestational age in nine of these triplet pregnancies. In all of these cases, at least one abnormal umbilical artery velocity waveform was present. Two infants were stillborn, and both had a grossly abnormal umbilical artery waveform (absent diastolic flow) recorded consistently for several weeks before fetal death. The use of umbilical artery Doppler studies may delineate those triplet pregnancies in which more intensive fetal surveillance is appropriate.

Intrauterine demise of two fetuses in an unsuspected triplet pregnancy. A case report.

Triplet pregnancy is an uncommon event. The chance that one or more fetuses will suffer intrauterine death in such a pregnancy is one in six, yet the mechanism of those fetal deaths is poorly understood. This paper reports on the delivery of a surviving triplet after the demise, many weeks apart, of the other two fetuses in an unrecognized triplet pregnancy.

Cognitive-communicative development of identical triplets, one with unilateral cleft lip and palate.

Identical male triplets, one with a complete unilateral cleft, were studied developmentally from 16 to 25 months of age and tested with several cognitive-communicative developmental measures. Measures of hearing and motor and behavioral development also were obtained. The triplets did not differ from normative data or from each other on hearing, motor, behavioral, and for the most part, cognitive-mental measures. All of the children were within normal limits on receptive communication measures; however, all were delayed on expressive measures. The triplet with the cleft was more delayed than his brothers. Discussion centers on the interaction of variables that may account for this differential effect in expressive measures in relation to the structural anomaly.

Triplet pregnancy in Lusaka.

A series of 8 triplet sets during the year 1980 at the University Teaching Hospital, Lusaka, has been analysed. The incidence was 1:2980 hospital deliveries. Age or parity of the mother did not appear to have any influence on foetal survival, in contrast to the birth weight and foetal presentation at the time of delivery. First triplet baby seemed to have a better chance of survival as compared to second and third triplet babies. There was prepondence of female babies. The corrected perinatal mortality was 273/1000 live births which is significantly high.

Triplet and quadruplet pregnancies and management.

The rate of multiple pregnancies with more than 2 fetuses has significantly increased since the introduction of ovulation induction agents. From 1970 through 1978, there were 19 triplets and 6 quadruplets in the authors' department, incidences of 1:696 and 1:5370, respectively. Eighteen (72%) of the 25 multiple pregnancies followed treatment with ovulation induction agents and 7 were spontaneous. The diagnosis of more than 2 fetuses was made earlier in the induced than in the uninduced pregnancies. Management, initiated upon diagnosis, included bed rest, high-protein diet, beta-mimetic agents, progestins, dexamethasone late in the second trimester, and selective cerclage. The mean gestational age was 34 weeks in the triplets and 35 weeks in the quadruplets. Forty-four percent of the deliveries were by cesarean section and the remainder were by vaginal delivery. The mean weight of the neonates was 1807 g in the triplets and 1950 g in the quadruplets. The mean overall Apgar score was 8.16, and the perinatal mortality was 185 per 1000, corrected (more than 28 weeks) to 137 per 1000. The main neonatal complications resulted from prematurity, and maternal complications noted were postpartum hemorrhage necessitating hysterectomy in 2 patients. The preferable mode of delivery cannot be stated dogmatically. Fetal outcome was similar in vaginal and cesarean deliveries among the various gestational age groups.

Triplet pregnancy in uterus didelphys with delivery interval of 72 days.

A unique case of triplet pregnancy in a woman with uterus didelphys is described, with fetuses A and B in the right uterine horn and fetus C in the left horn. Missed abortion of fetus A was diagnosed in the 22nd week of gestation by real-time ultrasonography, but only in the 27th week of gestation did the right uterine horn contract, resulting in expulsion of fetus A. Fetus B was delivered by cesarean section 2 hours later. Fetus C remained in the left uterine horn until the 37th week of gestation, when a viable 2490-g female infant was delivered by cesarean section. Triplet pregnancy occurs with sufficient frequency to be unremarkable; however, triplet pregnancy in a patient with uterus didelphys and with 72 days' lapse between the delivery of the first 2 fetuses and delivery of the third is a rare occurrence.
