    Aim: Sudden unexpected postnatal collapse is a life-threatening event and may occur in any newborn infant. Safe skin-to-skin contact, and awareness of sudden unexpected postnatal collapse are key to its prevention. The aim of this study was to survey the presence of skin-to-skin contact and/or sudden unexpected postnatal collapse protocols in the 70 perinatal centres in the Netherlands. Methods: We performed a survey among Dutch paediatricians to examine the safe skin-to-skin contact and sudden unexpected postnatal collapse protocols. Results: We received data from 59/70 (85%) perinatal centres. At least one case of sudden unexpected postnatal collapse was reported in 35/59 (59%) of these centres. Nearly half the centres had safe skin-to-skin contact and/or sudden unexpected postnatal collapse protocols. Ultimately, 16 protocols were available for analysis. They showed considerable differences in the type of perinatal care provided. Most protocols lacked recently published insights on safe skin-to-skin contact. Besides, protocols failed to incorporate awareness of and knowledge on how to prevent sudden unexpected postnatal collapse. Conclusion: This study underlines the importance of drawing up uniform, multidisciplinary guidelines containing recommendations for the prevention of sudden unexpected postnatal collapse in the Netherlands.</p

    Mitochondrial beta-oxidation of long-chain fatty acids requires the concerted action of three tightly integrated membrane-bound enzymes (carnitine palmitoyltransferase I and II and carnitine/acylcarnitine translocase) that transport them into mitochondria. Neonatal onset of carnitine palmitoyltransferase II (CPT II) deficiency is an autosomal recessive, often lethal disorder of this transport. We describe a novel splice-site mutation in the CPT II gene, found in a Moroccan family, of which four out of five children have died from the neonatal form of CPT II deficiency. Mutation detection studies at the mRNA level in the CPT II gene implied that the affected children were homozygous for the previously reported 534T insertion followed by a 25-bp deletion (encompassing bases 534-558). Studies of genomic DNA, however, revealed all patients to be compound heterozygous for this 534T ins/del 25 mutation, and for a new g-->a splice-site mutation in the splice-acceptor site of intron 2. Because of these findings, prenatal diagnosis was performed in chorionic villi of three new pregnancies. This did not reveal new compound heterozygous genotypes, and, after uneventful pregnancies, all children appeared to be healthy. The new mutation is the first splice-site mutation ever identified in CPT II deficiency. The fact that it was not discovered in the patient's cDNA makes this study another example of the incompleteness of mutation detection at the mRNA level in cases where a mutation leads to aberrant splicing or nonsense-mediated messenger deca

    Surveillance study of apparent life-threatening events (ALTE) in the Netherlands

    SIDS and ALTE are different entities that somehow show some similarities. Both constitute heterogeneous conditions. The Netherlands is a low-incidence country for SIDS. To study whether the same would hold for ALTE, we studied the incidence, etiology, and current treatment of ALTE in The Netherlands. Using the Dutch Pediatric Surveillance Unit, pediatricians working in second- and third-level hospitals in the Netherlands were asked to report any case of ALTE presented in their hospital from January 2002 to January 2003. A questionnaire was subsequently sent to collect personal data, data on pregnancy and birth, condition preceding the incident, the incident itself, condition after the incident, investigations performed, monitoring or treatment initiated during admission, any diagnosis made at discharge, and treatment or parental support offered after discharge. A total of 115 cases of ALTE were reported, of which 110 questionnaires were filled in and returned (response rate 97%). Based on the national birth rate of 200,000, the incidence of ALTE amounted 0.58/1,000 live born infants. No deaths occurred. Clinical diagnoses could be assessed in 58.2%. Most frequent diagnoses were (percentages of the total of 110 cases) gastro-esophageal reflux and respiratory tract infection (37.3% and 8.2%, respectively); main symptoms were change of color and muscle tone, choking, and gagging. The differences in diagnoses are heterogeneous. In 34%, parents shook their infants, which is alarmingly high. Pre- and postmature infants were overrepresented in this survey (29.5% and 8.2%, respectively). Ten percent had recurrent ALTE. In total, 15.5% of the infants were discharged with a home monitor. In conclusion, ALTE has a low incidence in second- and third-level hospitals in the Netherlands. Parents should be systematically informed about the possible devastating effects of shaking an infant. Careful history taking and targeted additional investigations are of utmost importance

    Congenital cytomegalovirus infection: review of the epidemiology and outcome

    Cytomegalovirus (CMV) is one of the most common viral causes of congenital infection. A future decision to lower its incidence by vaccination will depend on epidemiological conditions within a country and on the safety of the vaccine to be used, because a life vaccine may cause latency and subsequent reactivation that still may harm the fetus. The aim was to review the epidemiological studies published so far, with respect to factors that affect the incidence of congenital CMV infection, and factors that may influence its outcome, such as preexisting maternal immunity. The study included the data of 19 studies that were retrieved from a MEDLINE search during the period 1977 to 1997. The incidence of congenital CMV infection varied between 0.15% and 2.0% and seemed to correlate with the level of preexisting immunity in the population. Although preexisting maternal immunity was reported to strongly reduce transmission, the severity of congenital CMV infection (symptoms at birth and or sequelae later in life) was not significantly greater after virus transmission due to a primary infection of the mother as compared with recurrence or reinfection. The data indicate that preexisting immunity of the mother does not significantly mitigate the outcome of congenital infection. Moreover, life vaccines may bear a serious risk when transmittable to the fetus. Target Audience: Obstetricians and Gynecologists, Family Physicians Learning Objectives: After completion of this article, the reader will be able to describe the natural course of a CMV infection, to list the potential sequelae of a congenital CMV infection, to outline potential strategies to prevent transmission of CMV, and to summarize the diagnostic work up of a patient with a potential CMV infection

    Umbilical choline and related methylamines betaine and dimethylglycine in relation to birth weight

    Item does not contain fulltextBackground:Low birth weight (LBW) is associated with increased morbidity and mortality for the newborn and risk of chronic disease in adulthood. Choline plays an essential role in the integrity of cell membranes, methylation reactions, and memory development. We examined whether choline, betaine, and dimethylglycine (DMG) concentrations were associated with LBW in Dutch women.Methods:Blood was sampled from umbilical cords (UCs) at delivery in singleton pregnancies (n = 1,126). Maternal blood was sampled at 30-34 wk of gestational age (GA) (n = 366). We calculated birth weights standardized for GA and defined LBW as standardized birth weight </=2,500 g.Results:Maternal concentrations were lower as compared with UC concentrations and were not associated with birth weight. UC choline and betaine were inversely associated with birth weight (beta = -60 (-89, -31) and beta = -65 (-94, -36), respectively), whereas UC DMG was positively associated with birth weight (beta = 35 (6.1, 63)). Odds ratios for LBW were 4.12 (1.15, 14.78), 5.68 (1.24, 25.91), and 0.48 (0.09, 2.65) for the highest UC choline, betaine, and DMG quartiles, respectively, as compared with the lowest quartiles.Conclusion:We observed an increased risk of LBW with increased umbilical choline and betaine in venous UC blood. These results might reflect a change in choline consumption or metabolism or a disturbed placental function
