Coagulation and fibrinolysis studies were performed on 64 newborns; 16 premature infants with hyaline membrane disease (HMD), 17 newborns with other forms of respiratory distress syndrome (RDS) (8 of them were premature), 31 healthy newborns (11 of them were premature). All the babies were studied once in the first 48 hours of life. There was no significant difference between sick and healthy babies for 5 parameters; platelet count, factor VIII, fibrinogen, fibrin(ogen) degradation products, euglobulin lysis time. Factor II, VII and X were low in all infants, and premature infants had significantly lower levels compared to full term newborns. Factor V, plasminogen, alpha 2 macroglobulin (alpha 2M) and antithrombin III (AT III) levels were significantly lower in sick infants. Except for AT III, these deficiencies were not related to prematurity. No significant difference was found between HMD and other RDS. Of the 33 sick infants, 5 developed laboratory findings consistent with disseminated intravascular coagulation (DIC). The results indicate that the coagulation and fibrinolytic abnormalities reported are not specific to HMD.

We analyzed the gestational, parturitional, neonatal (GPN) histories of 281 severely mentally retarded patients with cerebral palsy to define the etiology or pathogenesis of cerebral palsy in each patient. No association between type of cerebral palsy and GPN histories was found except for an increase in spastic-athetoid patients in the breech delivery subgroup. Significant findings include: increased incidence of prematurity and postmaturity, small and large for-gestational age (GA) fetal size, a normal birthweight for GA distribution of patients with diabetic mothers, an excess of mothers greater than or equal to 35 and less than or equal to 20 years old, an increased immediately-previous sib interval of 2.59 years suggestive of an "infertility factor", an unremarkable GPN history in one third of the cases, in another one third GPN problems not usually associated with a high risk of CNS damage, and in one third gross complications which were probably responsible for the CP, including: an increased incidence of breech deliveries, twinning, prolonged and precipitous labor and placental complications; no increased association of athetosis and Rh incompatibility or incidence of toxemia was found. Disseminated intravascular coagulation due to prenatal death of a twin may have been the cause of brain damage in several patients.

Twelve neonates with sacrococcygeal teratoma (SCT) have been treated at British Columbia Children's Hospital over the past 5 years. Clinically significant coagulopathy developed in four of these neonates and two died, one before surgical intervention could be undertaken. Disseminated intravascular coagulation (DIC) was found in one patient and thrombocytopenia in another on preoperative laboratory studies. Etiology of the coagulopathy is unclear, but appears to be multifactorial. Although several clinical reviews have noted mortalities due to exsanguinating hemorrhage, no study has focused solely on this issue. The diagnosis of SCT in the neonate at high risk for development of coagulopathy is usually made prenatally. Premature labor is often precipitated by associated polyhydramnios and large tumor size. Fetal distress, prematurity, and low birth weight are common. Presence of placentamegaly, hydrops fetalis, and congestive heart failure are ominous prognostic signs. Early identification of patients at increased risk for development of hemorrhagic complications may allow optimization of their management. Cesarean section should minimize trauma to the SCT during delivery. Expeditious resection of the lesion may improve survival.

Disseminated intravascular coagulation (DIC) and other clotting abnormalities are common in sick newborn infants who have a variety of conditions. To document evidence of DIC at autopsy, immunoperoxidase staining of fibrin-related antigens (FRA) was used to detect intravascular microthrombi in liver, kidney, and lung from 127 newborns. Patients were selected from seven major disease groups: hyaline membrane disease/bronchopulmonary dysplasia, infection, meconium aspiration, necrotizing enterocolitis, congenital heart disease, other congenital anomalies, and extreme prematurity. Staining for FRA in intravascular microthrombi was seen in 40% of cases studied. The liver showed the highest frequency of intravascular microthrombi, located predominantly in the sinusoids. Unlike the adult kidney, the newborn kidney seldom had evidence of intravascular coagulation. Extravascular staining of FRA was observed in the renal distal tubular epithelium in 48 cases, many of which also had evidence of intravascular FRA staining. No significant differences in FRA staining patterns were seen among the disease groups except for cases of extreme prematurity in which all tissues showed minimal staining. Control tissues from SIDS patients also showed minimal FRA staining. Hepatic sinusoidal staining was the only tissue finding that correlated with thrombocytopenia, a clinical indicator of DIC. Despite the use of this immunohistochemical staining method, discrepancies between the clinical and autopsy diagnosis of DIC remain.

The syndrome of haemolysis, elevated liver enzymes and low platelets (HELLP Syndrome) is a consequence of severe preeclampsia/eclampsia. The clinical course is characterized by an unusual presentation with abdominal pain, and manifestations of inadequate haemostasis and excessive bleeding are common. Maternal and perinatal morbidity and mortality are high. We report our experience with 33 patients over a five-year period. The mean gestational age (GA) of the pregnancies was 34 +/- 2.8 wk including 11 patients who delivered 12 neonates of less than 34 wk GA. The most common presenting complaints were right upper quadrant or epigastric pain in 25 patients (76%) and nausea or vomiting in 14 patients (42%). Diagnosis was missed or delayed in 12 patients (36%). Thirty-one patients (94%) were delivered by Caesarean section and a deteriorating maternal condition was the most common indication for operative delivery. Twenty-three patients received general anaesthesia, eight received epidural anaesthesia and there were no complications related to the anaesthetic. There was clinical evidence of abnormal haemostasis: seven patients had excessive blood loss at Caesarean section, two had postpartum haemorrhage, three developed DIC and four developed wound haematoma. The average decrease in haemoglobin concentration was 32 g.L-1 and twelve patients (36%) received blood transfusions. There was one stillbirth. There were no neonatal deaths but morbidity was prominent and related primarily to prematurity. Delayed or missed diagnosis is common in HELLP syndrome and a premature delivery by Caesarean section is usual.(ABSTRACT TRUNCATED AT 250 WORDS)

Severe pregnancy-induced hypertension complicated by hemolysis, elevated liver enzymes and low platelets (HELLP) is considered an indication for immediate delivery, often resulting in premature or even previable infants. In five cases, temporary reversal of the HELLP syndrome was achieved using low-dose aspirin and corticosteroids. Pregnancy was prolonged an average of 4 weeks; three pregnancies were prolonged, beginning at less than or equal to 25 weeks, for an average of 5.5 weeks. Two of seven infants died, one from pulmonary hypoplasia due to oligohydramnios and the other from complications of prematurity. No long-term maternal morbidity was encountered, though one patient had peripartum disseminated intravascular coagulation and a seizure. A review of the literature supports the usefulness of low-dose aspirin in this setting; the impact of corticosteroids as part of the reversal strategy has not been discussed previously.

Twenty cases of fetal death complicating a multiple pregnancy after 20 weeks' gestation are reviewed. We evaluated gestational age at diagnosis and delivery (29.3 +/- 0.7 and 31.8 +/- 0.9 weeks, respectively), interval from diagnosis to delivery (2.6 +/- 0.6 weeks), and cause of fetal death as a group and by type of placentation (76.5% monochorionic). Eighty-five percent of the surviving fetuses were delivered preterm, and the four neonatal deaths were all due to extreme prematurity, with a mean (+/- SEM) birth weight of 794 +/- 237 g. Perinatal mortality was 585 per 1000, 450 for twin A and 750 for twin B. The causes of fetal death varied. Maternal disseminated intravascular coagulation was not diagnosed in any pregnancy in the present series. The high risk of complications related to preterm birth, compared with the low risk of problems related to continuation of a multiple pregnancy after diagnosis of a fetal death, argues in favor of conservative management in this setting.

Twins have higher rates of perinatal mortality, prematurity and its complications, low birth weight, intrauterine growth retardation, congenital anomalies, and long-term developmental morbidity. Monozygotic twins have lower birth weights and higher rates of congenital anomalies than dizygotic twins, which suggests that the etiology of these problems may be related to the monozygotic twinning process. Monochorionic twins have higher rates of perinatal mortality, intrapair birth weight discrepancies, and intrauterine growth retardation than dichorionic twins, which suggests that these complications may be related to placental vascular anastomoses. Monochorial vascular communications also can be responsible for twin transfusion syndrome, disseminated intravascular coagulation at birth and disruptive structural defects. Followup studies indicate that twins remain at a disadvantage for subsequent physical growth and intellectual achievement. The management of twins is challenging and fascinating because of the wide range of perinatal, neonatal, developmental, and parenting problems that can occur.

A delay of more than one month between the birth of twins is an unusual occurrence presenting the obstetrician and the neonatalogist with many questions regarding the management of the case. There is the risk of prematurity for the second twin as labor has already occurred in the pregnancy. There is also a risk of infection to both mother and fetus during the interval between the two deliveries, since the stump of the first twin's cord may precipitate ascending colonization from vagina and cervix. Germs frequently recovered from the vagina e.g. Ureaplasma urealyticum, are associated with prematurity. The latter has also been responsible for lethal interstitial pneumonia in the neonate. We present a case of a patient who though she delivered twice normally, had suffered 4 first trimester abortions and one late abortion, all spontaneous. Her eighth pregnancy was a twin pregnancy. She underwent a cerclage at 14 weeks, but went into labor at 17 weeks, when she delivered the first macerated twin. She was then treated with fenoterol and ampicillin; nevertheless she delivered twin the second at 26 weeks. This 750 g baby-girl presented with severe respiratory distress. Repeated chest X rays showed perihilar infiltrates which became nodular. All cultures were negative. At the end of the first week, when her condition was considered satisfactory, she deteriorated dramatically and died in respiratory failure and DIC. Tracheal aspirates were positive for Ureaplasma urealyticum.

In an effort to ascertain important epidemiologic and prognostic risk factors, we analyzed 33 cases of Staphylococcus aureus meningitis occurring over an 8-year period (1976 to 1984). Staphylococcus aureus caused 6% of all bacterial meningitis at our University Hospital. Fifty percent of cases were pediatric and included 7 newborn infants, of whom 71% were either premature or had low birth weight. Major underlying diseases were: central nervous system (CNS) disorders (55%), endocarditis (21%, predominantly intravenous drug abusers), other sites of infection (27%), and prematurity (24%). Fifty-seven percent of patients were bacteremic and 41% of those had concomitant bacteriuria. Hypoglycorrhachia was present in 27% of cases, positive cerebrospinal fluid (CSF) Gram stain in 20%, disseminated intravascular coagulation (DIC) in 19%, and methicillin-resistant organisms in 18%. Cerebrospinal fluid cultures remained positive for a protracted period (mean, 6.7 days) regardless of the presence or absence of a CNS shunt. Overall mortality was 21%. Favorable outcomes were associated with the eventual presence of sterile CSF (15.4% vs. 100% mortality) and the removal of foreign bodies (10% vs. 67% mortality). Mortality was also associated (p less than 0.5) with the presence of diabetes mellitus, age greater than 60, obtundation or coma on presentation, bacteremia, or DIC. Cure correlated (p less than .05) with CNS shunt-associated infections, age less than 1, normal neurologic examinations on presentation, or the absence of DIC or bacteremia.(ABSTRACT TRUNCATED AT 250 WORDS)
