Severe Neonatal Hyperbilirubinemia in the Netherlands
<p>Background: The occurrence of severe neonatal hyperbilirubinemia (SH) is partly attributed to nonhospitalized perinatal care. The Netherlands have a high frequency of home births and nonhospitalized perinatal care, and the incidence of SH is unknown. Objective: To assess the effects of home births and early hospital discharge on the incidence of SH in term-born infants in the Netherlands. Methods: In this nationwide prospective surveillance study between 2005 and 2009, infants (>= 37 weeks GA) were included if total serum bilirubin (TSB) was >= 500 mu mol/l or if they received an exchange transfusion when TSB was >= 340 mu mol/l. Results: Seventy-one infants had SH (incidence 10.4/100,000); 43 had a TSB >= 500 mu mol/l (incidence 6.3/100,000) and 45 (63%) underwent an exchange transfusion. 26% of the infants with SH were born at home, which is similar to 22% of all term infants who are born at home in the Netherlands (p = 0.41). Maximum TSB levels were similar in infants born at home (523 +/- 114 mu mol/l) and infants born in hospital (510 +/- 123 mu mol/l; p = 0.70). Of the 51 infants born in hospital, 33 were discharged and readmitted with SH, with maximal TSB levels (567 +/- 114 mu mol/l), which were higher than in infants who remained hospitalized (406 +/- 47 mu mol/l; p = 0.0001). Conclusion: The incidence of severe hyperbilirubinemia in term-born infants in the Netherlands is 10.4 per 100,000, which is similar to other developed countries. Home birth and early hospital discharge do not necessarily lead to a higher incidence of SH, provided that perinatal home care is well organized. Copyright (C) 2013 S. Karger AG, Basel</p>
Nemaline myopathy caused byTNNT1 mutations in a Dutch pedigree
Nemaline myopathy (NM) is genetically heterogeneous disorder characterized by early onset muscular weakness and sarcoplasmatic or intranuclear inclusions of rod-shaped Z-disk material in muscle fibers. Thus far, mutations in seven genes have been identified as cause of NM. Only one singleTNNT1 nonsense mutation has been previously described that causes autosomal recessive NM in the old order Amish with a very specific clinical phenotype including rapidly progressive contractures. Here, we report a patient who is compound heterozygous for a c.309+1G>A mutation and an exon 14 deletion in theTNNT1 gene. This report confirms the specific clinical phenotype ofTNNT1 NM and documents two newTNNT1 mutations outside the old order Amish
Growth and prevalence of feeding difficulties in children with Robin sequence : a retrospective cohort study
Objectives: In addition to breathing problems, patients with Robin sequence (RS) often encounter feeding difficulties (FD). Data regarding the occurrence of FD and possible influencing factors are scarce. The study aim was to elucidate these factors to improve treatment strategies. Material and methods: A retrospective comparative cohort study was conducted, consisting of 69 infants diagnosed with both RS and a cleft palate and 64 isolated cleft palate only (iCPO) infants. Data regarding FD, growth, and airway intervention were collected during the first 2 years of life. A systematic review of the literature was conducted to identify reported FD in RS patients. Results: RS patients had more FD (91 %) than iCPO patients (72 %; p = 0.004). Also, nasogastric (NG)-tube feeding was necessary more frequently and for a longer period (both p <0.001). Growth was lower in RS than iCPO infants (p = 0.008) and was not affected by the kind of airway management (conservative/surgical; p = 0.178), cleft palate grade (p = 0.308), or associated disorders (p = 0.785). By contrast, surgical intervention subtype did significantly affect growth. Mean reported FD for RS in the literature is 80 % (range = 47–100 %), and 55 % (range = 11–100 %) of infants need NG-tube feeding. Conclusions: FD is present in a large proportion of infants with RS, which indicates the need for early recognition and proper treatment to ensure optimal growth. Growth during the first 2 years of life is significantly lower in RS patients than iCPO patients, which indicates the need for careful attention and long-term follow-up. Clinical relevance: This study indicates the need for early recognition and proper treatment of FD in RS to ensure optimal growth. In addition, growth needs careful attention and long-term follow-up
