Summary Idiopathic thrombocytopenic purpura (ITP) occurs more commonly in young women and is one of the commonest immune mediated disorders in pregnancy. It may exist as an incidental finding in an otherwise healthy pregnant woman or may be associated with symptomatic reduction in the platelet count and varying degrees of clinical hemorrhage. The condition termed incidential thrombocytopenia of pregnancy is invariably associated with a platelet count of greater than 100×109/L and a very low incidence of fetal thrombocytopenia. Symptomatic thrombocytopenia is more commonly associated with low platelet counts in the fetus (estimated between 20%–40%). It has recently been suggested that the incidence of fetal thrombocytopenia is substantially lower than this figure. The management of ITP in pregnancy is complicated by the fact that fetal thrombocytopenia is difficult to diagnose and carries substantial risks during the delivery process with rare cases of fetal hemorrhage occurring spontaneously in utero. Unfortunately there are no laboratory studies that can be performed precisely in the mother that may predict the occurrence of fetal thrombocytopenia. Maternal management is usually directed towards treatment of maternal symptoms. Maternal treatment or response to treatment is inconsistently associated with predictible changes in the fetal platelet count. Obstetric management is aimed at reducing the risks of life threatening fetal hemorrhage occurring at the time of delivery, and fetal management is directed towards the obtaining of fetal platelet samples in order to plan an appropriate strategy for obstetrical delivery. Fetal blood samples are obtained either by a scalp vein puncture at the time of delivey or earlier in gestation by the use of the newer technique termed percutaneous umbilical blood sampling. Fetuses with platelet counts of less then 50×109/L are generally delivered by cesarean section whereas those with counts greater than 50×109/L are allowed to proceed with vaginal delivery assuming no obstetrical contraindications exist. The use of IVIgG therapy during pregnancy has theoretical implications on improving platelet counts in the mother in situations of severe hemorrhage, however cannot be considered to be appropriate treatment for the prevention of fetal thrombocytopenia, since the exogenous transport of IVIgG across the placenta appears to be inconsistent and unpredictible. The mainstay of maternal management continues to be corticosteroids and women who have failed this therapy, who continue to have bleeding or those in whom iatrogenic complications of steroids exist are candidates for IVIgG.Presented at the International Workshop on ITP, August 26 and 27, 1988, Lucerne, Switzerland 相似文献

ObjectiveRetrospective analysis of the feasibility, safety and results of patent ductus arteriosus (PDA) stenting in low birth weight babies weighing < 2 kg. Background: Stenting of patent ductus arteriosus is a well known palliative technique for several years as an alternative to shunt surgery in babies weighing > 2.5–3 kg. Ductal stenting in babies weighing less than 2 kg is not done routinely all around the world due to limited experience and concerns regarding its feasibility and safety in such small subset.MethodsRecords of patients who underwent PDA stenting at our institution from June 2014 to December 2016 were reviewed. In this period, we attempted to do PDA stenting using femoral artery approach in babies weighing < 2 kg. Echocardiography and colour Doppler were used for patient selection and assessment of procedural outcome.ResultsPDA stenting using femoral artery approach was successful in all 5 patients weighing < 2 kg. In this group, patient age ranged from 2 days to 16 days and weighed 1.8 kg to 1.97 kg. All patients had good post-procedure outcome. One patient had stent malposition from aortic end towards main pulmonary artery which was managed by an additional stent.ConclusionPDA stenting is feasible and safe with good end results in carefully selected low birth weight babies weighing < 2 kg. 相似文献

To evaluate the influence of echocardiographic examination in the clinical management of the sick neonate, 241 patients, admitted to the neonatal intensive care unit of a tertiary referral center that had echocardiograms with data available for review, were enrolled in a retrospective study. Asymptomatic murmurs (45%) followed by extracardiac anomalies/dysmorphic features (24%) were the most common clinical indications for requesting an echocardiogram. Congenital structural abnormalities (33%), hemodynamically significant patent arterial duct (3%), persistent pulmonary hypertension of the newborn (6%), and left ventricular dysfunction (3%) were the echocardiographic findings that subgrouped as structural or functional abnormalities. Patent oval foramen and hemodynamically nonsignificant patent arterial duct (20%) and physiologic pulmonary artery stenosis (1%) were categorized as normal structural group. Thirty‐four percent of neonates had normal heart anatomy. This investigation changed the clinical management in at least 66% of newborns scanned, including emergency surgical intervention for 7%, medical treatment for 22%, and routine cardiologic follow‐up for 37% of patients. Asymptomatic murmur in our critically ill neonates has been associated with a higher incidence of cardiac disease. Hence, echocardiography is an important tool for diagnosis of cardiac abnormalities that can influence the management and outcome of the sick newborn in the intensive care unit. A preliminary echocardiogram performed by the neonatologist under the supervision of a pediatric cardiologist for interpretation and review is an alternate when there is not a cardiologist “in house.” 相似文献

Summary Iron and folate status was assessed in 79 multiparous French women and 21 immigrant parturient women, previously defined as belonging to a high risk population for nutritional deficiencies, and their newborn infants. Maternal hemoglobin was correlated with ferritinemia and with serum folate values; weight gain during pregnancy appeared to be correlated with mother's iron status at start of labour and gestation duration with folate status. The need of iron and folic supplementation is emphasized for such groups. While a correlation appeared between maternal and newborn values for serum and red blood cell folates and for the RBC indices, no statistical difference was found between the infants born to iron or folate deficient mothers when compared with others. 相似文献

Objective
It is unknown whether GH secretion of children with growth hormone deficiency (GHD) is already diminished at birth. We aimed to determine the GH content within archived dried blood spots of newborn screening cards from children diagnosed with GHD at childhood.Design
At our hospital, all children with the diagnosis of GHD and an actual age < 10 years were identified. For 16 patients (mean age, 7.4 years; range, 1.0–9.7), screening cards were available. The archived dried blood from the first 48 to 96 h of life was eluated in buffer of a highly sensitive hGH-ELISA to measure the GH content. Reference values were calculated based on 600 anonymous newborn screening cards of different ages.Results
Median GH content within the archived dried blood spots of the reference had declined by 30% during the first year and by further 35% during the next 8.5 years of storage. After correction for time of storage, four out of the 16 archived dried blood spots of the GHD children contained low amounts of GH (≤ 5th percentile). Diminished GH secretion at birth was absent in isolated GHD, but associated with multiple pituitary hormone deficiency (MPHD) (P = 0.0013), ectopic neurohypophysis (P = 0.0013), lower GH test peak values (P = 0.02) and higher weight at diagnosis (P = 0.015).Conclusions
Children with isolated GHD have normal GH secretory capacity during the first week of life while the majority of children with MPHD and pituitary malformation were GH deficient immediately after birth. 相似文献19.

Pulmonary arteriovenous malformation (PAVM) is a rare cause of cyanosis in newborn. A 12‐day‐old male newborn (2.8 kg) was referred to our hospital with the complaints of cyanosis and respiratory distress. On two‐dimensional echocardiography, the right pulmonary artery (PA) appeared larger than left PA and the left atrium, left ventricle were dilated. The right heart chambers were in normal limits. A color flow Doppler echocardiogram revealed a turbulent flow due to a PAVM originating from medium branch of right PA, and continuous wave Doppler showed continuous flow pattern. Agitated saline injection resulted in the delayed appearance of the contrast in the left‐side chambers three to four heart cycles after appearance in the right‐side chambers; the study was considered positive and indicative of an intrapulmonary shunt. Selective angiography of the right PA confirmed the diagnosis of a large solitary PAVM in the right middle lobe with a feeding artery. Amplatzer vascular plug I, which is designed to close abnormal vascular structures, was chosen to close the PAVM. The deployment of device performed safely and the oxygen saturation of baby increased to 95% immediately after deployment. Heart failure and respiratory distress also resolved after the procedure. 相似文献
