Abstract
OBJECTIVE Whether the day of the week on which the child presents affects timely diagnosis and risk of diabetic ketoacidosis (DKA) in children with new-onset type 1 diabetes (T1D) is not known. RESEARCH DESIGN AND METHODS We used data of 30,717 children with new-onset T1D during the last 10 years from the German Prospective Diabetes Registry. We determined the odds ratios of T1D diagnosis and DKA on a weekday, public holiday, and school vacation. RESULTS Compared with workdays, the odds ratios of being diagnosed with T1D were lower on weekends (0.39 [95% CI, 0.38-0.41]), public holidays (0.57 [0.53-0.63]), and school vacations (0.83 [0.80-0.85]). The odds of DKA diagnosis were also reduced on weekends (0.55 [0.52-0.59]), public holidays (0.73 [0.63-0.84]), and school vacations (0.85 [0.80-0.90]). Results did not change during the coronavirus 2019 pandemic. CONCLUSIONS New-onset T1D and DKA in children are more often diagnosed during weekdays than weekends and holidays.

Abstract
Purpose: The primary endpoint results from the comparing alternative ranibizumab dosages for safety and effcacy in retinopathy of prematurity (CARE-ROP) core study identified ranibizumab as an effective treatment to control acute retinopathy of prematurity (ROP). This study reports the 1- and 2-year follow-up data focusing on long-term functional outcomes and safety. Methods: The CARE-ROP trial compared 0.12 mg versus 0.20 mg ranibizumab in 20 infants with ROP in a multicentric, prospective, randomized, double-blind, controlled study design. Sixteen patients entered the follow-up period. An ophthalmologic assessment at one year postbaseline was acquired from all 16 patients and a neurodevelopmental assessment at two years postbaseline was acquired from 15 patients. Results: Fifteen of 16 infants were able to fixate and follow moving objects at one year postbaseline treatment. One child progressed to stage 5 ROP bilaterally between the end of the core study and the 1-year follow-up (first seen at PMA 75 weeks). Mean spherical equivalents were −1.9 diopters (D) and −0.75 D in the 0.12 mg and the 0.20 mg treatment arms. Strabismus was present in seven and nystagmus in five out of 16 infants. Mental development scores were within normal limits in six out of ten patients with available data. No statistically significant difference was observed between the two treatment arms. Conclusion: Neurodevelopmental and functional ocular outcomes 1 and 2 years after treatment with ranibizumab are reassuring regarding long-term safety. Late reactivation of ROP, however, represents a challenge during the follow-up phase and it is of utmost importance that regular follow-ups are maintained.

Abstract
BACKGROUND Diabetic ketoacidosis (DKA) is a potentially life-threatening metabolic disorder that can occur with manifestation of type 1 diabetes mellitus (T1D). The aim of this study was to analyze the incidence of DKA at the time of the diagnosis of T1D in childhood and adolescence, the risk factors, and regional approaches to reduce the incidence of ketoacidosis. METHODS We investigated the proportion of patients under 18 years of age with DKA (defined as pH <7.3, severe DKA pH <7.1) at the manifestation of T1D in Germany in the period 2000-2019, based on data from the German-Austrian registry of diabetes (Diabetes-Patienten-Verlaufsdokumentation, DPV). The influence of the following factors was evaluated: year of manifestation, age, sex, family history of migration (MiH), and distance from the hospital. Moreover, data from the region with and the region without a pilot screening project from 2015 onwards were compared. RESULTS Of the 41 189 patients with manifestation of T1D, 19.8% presented with DKA (n = 8154, slight increase [p <0.001] over the study period) and 6.1% (n = 2513) had severe DKA. Children under 6 years of age had DKA more often than adolescents (12-17 years) (21.7% versus 18.6%, OR 1.22 {95% CI: [1.14; 1.30]}). Girls had a higher rate of DKA than boys (20.5% versus 19.2%, OR 1.10 [1.03; 1.14]), and patients with MiH were more likely to have DKA than those without MiH (21.4% versus 18.2%, OR 1.40 [1.32; 1.48]). In the region with a pilot screening project, the DKA rate stayed the same, at 20.6%, while in the control region the rate was 22.7% with a decreasing tendency. CONCLUSION The frequency of DKA at the time of diagnosis of T1D did not decrease between 2000 and 2019 and increased towards the end of the observation period. Children with MiH, children under 6, and girls were at a higher risk of DKA.

Abstract
OBJECTIVE To determine if survival rates of preterm infants receiving active perinatal care improve over time. DESIGN The German Neonatal Network is a cohort study of preterm infants with birth weight <1500 g. All eligible infants receiving active perinatal care are registered. We analysed data of patients discharged between 2011 and 2016. SETTING 43 German level III neonatal intensive care units (NICUs). PATIENTS 8222 preterm infants with a gestational age between 22/0 and 28/6 weeks who received active perinatal care. INTERVENTIONS Participating NICUs were grouped according to their specific survival rate from 2011 to 2013 to high (percentile >P75), intermediate (P25-P75) and low (<P25) survival. We compared these survival rates with data in 2014-2016. MAIN OUTCOME MEASURES Death by any cause before discharge. RESULTS Total survival increased from 85.8% in 2011-2013 to 87.4% in 2014-2016. This increase was due to reduced mortality of NICUs with low survival rates in 2011-2013. Survival increased in these centres from 53% to 64% in the 22-24 weeks strata and from 73% to 84% in the 25-26 weeks strata. CONCLUSIONS Our data support previous reports that active perinatal care of very immature infants improves outcomes at the border of viability and survival rates at higher gestational ages. The high total number of surviving infants below 24 weeks of gestation challenges national recommendations exclusively referring to gestational age as the single criterion for providing active care. However, more data are needed before recommendations for parental counselling should be reconsidered. TRIAL REGISTRATION Approval by the local institutional review board for research in human subjects of the University of Lübeck (file number 08-022) and by the local ethic committees of all participating centres has been given.

Abstract
SummaryA 9½-year-old girl suffered from intermitting tremor and jitteriness of her left hand and oral muscles every 4 to 6 weeks with long lasting episodes. Clinically myoclonias and dystonic positioning of the left arm, hand and facial muscles were seen. No evidence of trauma, infection or inborn errors of metabolism was found. Successful therapy with carbamazepine was initiated while L-DOPA failed. An ictal 99m-Tc-HMPAO-SPECT showed severe asymmetry with focal hyperperfusion of the contralateral right thalamus and basal ganglia as well as of the bifrontal cortex, whereas no anatomical lesions were found by MRI. In contrast, an interictally performed 99m-Tc-HMPAO SPECT showed hypoperfusion of the right thalamus and normalisation of the frontal perfusion under medical treatment. These 99m-Tc-HMPAO-SPECT findings may provide new insights into the localisation and pathophysiological pathways of idiopathic childhood dystonia.

Abstract
BACKGROUND Levels or fluctuations in the partial pressure of CO2 (PCO2) may affect outcomes for extremely low birth weight infants. OBJECTIVES In an exploratory analysis of a randomized trial, we hypothesized that the PCO2 values achieved could be related to significant outcomes. METHODS On each treatment day, infants were divided into 4 groups: relative hypocapnia, normocapnia, hypercapnia, or fluctuating PCO2. Ultimate assignment to a group for the purpose of this analysis was made according to the group in which an infant spent the most days. Statistical analyses were performed with analysis of variance (ANOVA), the Kruskal-Wallis test, the χ2 test, and the Fisher exact test as well as by multiple logistic regression. RESULTS Of the 359 infants, 57 were classified as hypocapnic, 230 as normocapnic, 70 as hypercapnic, and 2 as fluctuating PCO2. Hypercapnic infants had a higher average product of mean airway pressure and fraction of inspired oxygen (MAP × FiO2). For this group, mortality was higher, as was the likelihood of having moderate/severe bronchopulmonary dysplasia (BPD), necrotizing enterocolitis (NEC), and poorer neurodevelopment. Multiple logistic regression analyses showed an increased risk for BPD or death associated with birth weight (p < 0.001) and MAP × FiO2 (p < 0.01). The incidence of adverse neurodevelopment was associated with birth weight (p < 0.001) and intraventricular hemorrhage (IVH; p < 0.01). CONCLUSIONS Birth weight and respiratory morbidity, as measured by MAP × FiO2, were the most predictive of death or BPD and NEC, whereas poor neurodevelopmental outcome was associated with low birth weight and IVH. Univariate models also identified PCO2. Thus, hypercapnia seems to reflect greater disease severity, a likely contributor to differences in outcomes.

Abstract
SummaryClinical trials evaluating the potential benefit of anticoagulant treatment in pregnant women with inherited thrombophilia are based on the observation that a genetic predisposition to thrombosis is associated with frequent abortions and preterm birth. It was the aim of our study to delineate the impact of genetic polymorphisms with prothrombotic and antithrombotic effects on the occurrence of preterm birth in a large cohort of very-low-birth-weight (VLBW)-infants and their mothers. We examined the factor V Leiden and the prothrombin G20210A mutation, the factor VII 121del/ins and the factor XIII Val34Leu polymorphism in preterm very-low-birth-weight (VLBW, n=593) and term-born-infants (n=278) and their mothers (n=785).The primary outcome was preterm vs. term birth. From all polymorphisms tested, the maternal factor VII-121del/ins polymorphism (26.2 vs. 17.6 %; p=0.009) and the infant’s factor VII-121del/ins polymorphism (29.0 vs. 20.0 %; p=0.009) were more frequent in singletonVLBW and their mothers compared to term infants and their mothers. Furthermore, the frequency of the factor XIII-Val34Leu polymorphism was significantly lower in singleton VLBW than in term infant controls (5.1 vs. 9.6%, p=0.025). In a multivariate regression analysis, previous preterm delivery (OR=3.8, 95% CI: 1.7–8.4), the maternal carrier status of the factor-VII-121del/ins polymorphism (OR=1.7, 95% CI: 1.12–2.5, p=0.007) and the lower frequency of infant’s factor-XIII-Val34Leu polymorphism (OR=0.53; 95% CI: 0.29–0.96; p=0.038) were found to be independently associated with preterm delivery. InVLBW mothers with pathological CTG as cause of preterm delivery, the frequency of factor V Leiden mutation was significantly increased compared to VLBW mothers without pathological CTG (14.1 vs. 6.1%, p=0.01).The investigated haemostasis gene polymorphisms have a much lower impact on subsequent preterm delivery than known risk factors such as previous preterm birth. The reported association of the factor-VII-121del/ins polymorphism on preterm delivery and its clinical relevance needs to be further elucidated.

Abstract
BACKGROUND Tolerating higher partial pressures of carbon dioxide (PCO2) in mechanically ventilated extremely low birthweight infants to reduce ventilator-induced lung injury may have long-term neurodevelopmental side effects. This study analyses the results of neurodevelopmental follow-up of infants enrolled in a randomised multicentre trial. METHODS Infants (n=359) between 400 and 1000 g birth weight and 23 0/7-28 6/7 weeks gestational age who required endotracheal intubation and mechanical ventilation within 24 hours of birth were randomly assigned to high PCO2 or to a control group with mildly elevated PCO2 targets. Neurodevelopmental follow-up examinations were available for 85% of enrolled infants using the Bayley Scales of Infant Development II, the Gross Motor Function Classification System (GMFCS) and the Child Development Inventory (CDI). RESULTS There were no differences in body weight, length and head circumference between the two PCO2 target groups. Median Mental Developmental Index (MDI) values were 82 (60-96, high target) and 84 (58-96, p=0.79). Psychomotor Developmental Index (PDI) values were 84 (57-100) and 84 (65-96, p=0.73), respectively. Moreover, there was no difference in the number of infants with MDI or PDI <70 or <85 and the number of infants with a combined outcome of death or MDI<70 and death or PDI<70. No differences were found between results for GMFCS and CDI. The risk factors for MDI<70 or PDI<70 were intracranial haemorrhage, bronchopulmonary dysplasia, periventricular leukomalacia, necrotising enterocolitis and hydrocortisone treatment. CONCLUSIONS A higher PCO2 target did not influence neurodevelopmental outcomes in mechanically ventilated extremely preterm infants. Adjusting PCO2 targets to optimise short-term outcomes is a safe option. TRIAL REGISTRATION NUMBER ISRCTN56143743.

Abstract
BACKGROUND Tolerating higher partial pressure of carbon dioxide (pCO2) in mechanically ventilated, extremely low birthweight infants might reduce ventilator-induced lung injury and bronchopulmonary dysplasia. We aimed to test the hypothesis that higher target ranges for pCO2 decrease the rate of bronchopulmonary dysplasia or death. METHODS In this randomised multicentre trial, we recruited infants from 16 tertiary care perinatal centres in Germany with birthweight between 400 g and 1000 g and gestational age 23-28 weeks plus 6 days, who needed endotracheal intubation and mechanical ventilation within 24 h of birth. Infants were randomly assigned to either a high target or control group. The high target group aimed at pCO2 values of 55-65 mm Hg on postnatal days 1-3, 60-70 mm Hg on days 4-6, and 65-75 mm Hg on days 7-14, and the control target at pCO2 40-50 mmHg on days 1-3, 45-55 mm Hg on days 4-6, and 50-60 mm Hg on days 7-14. The primary outcome was death or moderate to severe bronchopulmonary dysplasia, defined as need for mechanical pressure support or supplemental oxygen at 36 weeks postmenstrual age. Cranial ultrasonograms were assessed centrally by a masked paediatric radiologist. This trial is registered with the ISRCTN registry, number ISRCTN56143743. RESULTS Between March 1, 2008, and July 31, 2012, we recruited 362 patients of whom three dropped out, leaving 179 patients in the high target and 180 in the control group. The trial was stopped after an interim analysis (n=359). The rate of bronchopulmonary dysplasia or death in the high target group (65/179 [36%]) did not differ significantly from the control group (54/180 [30%]; p=0·18). Mortality was 25 (14%) in the high target group and 19 (11%; p=0·32) in the control group, grade 3-4 intraventricular haemorrhage was 26 (15%) and 21 (12%; p=0·30), and the rate of severe retinopathy recorded was 20 (11%) and 26 (14%; p=0·36). INTERPRETATION Targeting a higher pCO2 did not decrease the rate of bronchopulmonary dysplasia or death in ventilated preterm infants. The rates of mortality, intraventricular haemorrhage, and retinopathy did not differ between groups. These results suggest that higher pCO2 targets than in the slightly hypercapnic control group do not confer increased benefits such as lung protection. FUNDING Deutsche Forschungsgemeinschaft.

Abstract
AIM ATP-binding cassette member A 3 (ABCA3) plays a critical role for the transport of surfactant phospholipids into the lamellar bodies of type II alveolar epithelial cells. Term infants carrying the E292V missense mutation of the gene encoding ABCA3 are likely to develop respiratory distress syndrome, and the mutation has also been linked to interstitial lung disease in paediatric patients. The aim of this study was to investigate the association of the E292V genotype with pulmonary morbidity in a large cohort of very-low-birth-weight (VLBW) infants. METHODS We performed a genetic association study with a prospective, population-based multi-centre cohort of 3177 VLBW infants born in 16 German study centres between 2003 and 2009 (German Neonatal Network). The ABCA3 genotype was determined by restriction fragment length polymorphism-PCR in genomic DNA samples derived from buccal swabs. RESULTS In a large cohort of 3177 VLBW infants, 11 individuals were found to be heterozygote for the E292V mutation (0.34%). After stratification according to ABCA3 genotype, no differences were noted for clinical characteristics, necessary treatments and neonatal pulmonary outcomes. CONCLUSIONS Within the size limits of our study cohort, the ABCA3 missense mutation E292V had no remarkable effect on pulmonary outcome in VLBW infants. Present results do not rule out the possibility that E292V phenotype is associated with minor difference in the morbidity.

Abstract
PURPOSE Scrotal ultrasound, color Doppler and spectral Doppler analysis of intratesticular arteries are the most common and important examinations in boys with scrotal pain. In the existing literature information concerning feasibility and reference values of color Doppler and spectral Doppler in small testes is inconsistent. MATERIALS AND METHODS In the present study 102 boys from 2 days to 16 years old without present or anamnestic scrotal disease were examined in a standardized manner. Using linear scanners (9 - 14 mHz), testicular volumetry and spectral Doppler analysis of typical intratesticular arteries were performed and the paratesticular structures were examined. For analysis we grouped the testes by volume and compared the measured values V. max syst., V. max enddiast., and RI. RESULTS In all test subjects a complete examination with spectral Doppler analysis of intratesticular arteries could be performed. With increasing testicular volume, there is a linear increase in blood flow velocities V. max syst. and V. enddiast. Irrespective of age and testicular volume, the RI of the intratesticular arteries is 0.54 ± 0.08. CONCLUSION In contrast to published data, this study shows that color Doppler and spectral Doppler of testicular arteries can be regularly performed even in small testes of less than 1 ml. Reference values for blood flow velocities and RI were found and should improve the diagnostic value of testicular ultrasound examinations in children.

Abstract
In all known congenital imprinting disorders an association with aberrant methylation or mutations at specific loci was well established. However, several patients with transient neonatal diabetes mellitus (TNDM), Silver-Russell syndrome (SRS) and Beckwith-Wiedemann syndrome (BWS) exhibiting multilocus hypomethylation (MLH) have meanwhile been described. Whereas TNDM patients with MLH show clinical symptoms different from carriers with isolated 6q24 aberrations, MLH carriers diagnosed as BWS or SRS present only the syndrome-specific features. Interestingly, SRS and BWS patients with nearly identical MLH patterns in leukocytes have been identified. We now report on the molecular findings in DNA in three SRS patients with hypomethylation of both 11p15 imprinted control regions (ICRs) in leukocytes. One patient was a monozygotic (MZ) twin, another was a triplet. While the hypomethylation affected both oppositely imprinted 11p15 ICRs in leukocytes, in buccal swab DNA only the ICR1 hypomethylation was visible in two of our patients. In the non-affected MZ twin of one of these patients, aberrant methylation was also present in leukocytes but neither in buccal swab DNA nor in skin fibroblasts. Despite mutation screening of several factors involved in establishment and maintenance of methylation marks including ZFP57, MBD3, DNMT1 and DNMT3L the molecular clue for the ICR1/ICR2 hypomethylation in our patients remained unclear. Furthermore, the reason for the development of the specific SRS phenotype is not obvious. In conclusion, our data reflect the broad range of epimutations in SRS and illustrate that an extensive molecular and clinical characterization of patients is necessary.

Abstract
BACKGROUND Recently in a report of a single center a method has been described to apply surfactant via a thin endotracheal catheter to very low birth weight infants spontaneously breathing with nasal continuous positive airway pressure. We now analyzed available multicenter data. PATIENTS AND METHODS In a multicenter study investigating genetic risk factors, clinical and outcome data and data of antenatal and postnatal treatment of infants with a birth weight below 1,500 g were prospectively recorded. The measures of infants treated with the new method of surfactant application were compared to those of infants who received standard care. The analysis was restricted to infants with a gestational age below 31 weeks (n=1,541). RESULTS 319 infants were treated with the new method and 1,222 with standard care. The need for mechanical ventilation during the first 72 h (29% vs. 53%, p<0.001), the rate of bronchopulmonary dysplasia defined as oxygen at 36 weeks of postmenstrual age (10.9 % vs. 17.5%, p=0.004) and the rate of death or bronchopulmonary dysplasia were significantly lower in the treatment group than in the standard care group. Surfactant, theophyllin, caffeine and doxapram were significantly more often and analgetics, catecholamines and dexamethasone were significantly less frequently used in the treatment group. CONCLUSIONS A new method of surfactant application was associated with a lower prevalence of mechanical ventilation and better pulmonary outcome. A prospective controlled trial is required to determine whether this approach is superior to standard care.

Abstract
BACKGROUND The insertion/deletion polymorphism of the angiotensin-converting enzyme (ACE-ins/del) and the angiotensin II type 1 receptor 1166A/C polymorphism (ATR1166A/C) were reported to be associated with several unfavorable outcome parameters in preterm infants like bronchopulmonary dysplasia, persistent ductus arteriosus and impaired insulin sensitivity. OBJECTIVE To confirm the above-mentioned associations in a large cohort of very-low-birthweight (VLBW) infants. METHOD Clinical data of VLBW infants were prospectively recorded. The ACE-ins/del polymorphism and the ATR1166A/C polymorphism were determined by polymerase chain reaction in 1,209 and 1,168 infants, respectively. RESULTS There was no significant association between ACE-ins/del or ATR1166A/C genotype and outcome parameters (death, intraventricular hemorrhage, sepsis, bronchopulmonary dysplasia, ventilation, supplemental oxygen at discharge, postnatal treatment with insulin, surgery for intestinal perforation/necrotizing enterocolitis/retinopathy of prematurity/persistent ductus arteriosus. CONCLUSION Both known functional polymorphisms of the renin-angiotensin system do not seem to be associated with the outcome of VLBW infants.

Abstract
Human bocavirus (HBoV) was recently described as a new member of the Parvoviridae. In order to investigate the suggested association of HBoV with respiratory and gastric disease in infants and young children, sera of 357 paediatric patients hospitalized with infectious and non-infectious diseases were retrospectively analyzed for the presence of HBoV DNA and virus-specific antibodies using quantitative PCR and ELISA, respectively. HBoV seroprevalence was determined to range from 25% in infants younger than 1 year of age to 93% in children aged more than 3 years. Viral loads between 1 x 10(2) and 1.2 x 10(6) geq/mL were observed in 6.7% (20/297) of sera obtained preferentially from young children suffering from infectious diseases. HBoV genomes were furthermore detected in 5% (3/60) of sera collected from individuals with non-infectious illnesses. HBoV DNA was present most frequently in patients with respiratory disease (9.6%). Whereas only 5.2% of patients with upper respiratory tract disease were viraemic, HBoV DNA was found in 14.6% and 10.0% of patients with lower respiratory tract illness and pneumonia, respectively. Acute HBoV infections were also observed in 7.5% of patients with gastroenteritis and in one child with inflammatory bowel disease. None of 77 patients hospitalized for various other infectious diseases (e.g. rash, urinary tract infection, meningitis) displayed viraemia. In 60.9% and 47.8% of DNA-positive children, HBoV-specific IgM and IgG was observed, respectively. The present prospective study provides comprehensive data on the clinical association of acute HBoV infection with respiratory illness and on the seroprevalence of virus-specific antibodies in children.

Abstract
Human bocavirus (HBoV) was recently detected in samples from children and infants with infections of the respiratory tract. Here we analyze the prevalence of IgG and IgM antibodies against HBoV virus-like VP2 particles in healthy adult blood donors and children using a newly established standardized enzyme-linked immunosorbent assay. Virus-specific IgG antibodies were frequently detected in infants with active viremia and respiratory illness (10/24, 42%) and in young children without detectable HBoV genomes in their blood (27/52, 52%). In sera obtained from healthy adults, ubiquitous VP2-specific antibodies were found in 280/299 (94%) cases. HBoV-specific IgM antibodies were detected in 10/24 (42%) of sera samples obtained from HBoV DNA-positive children, and in 6/24 (25%) the sera displayed equivocal responses. In contrast, VP2-specific IgM was not detectable in samples obtained from 52 children without detectable amounts of HBoV genomes in their blood. Only 2/299 sera samples from healthy adult blood donors were found to be IgM-positive (1%), and equivocal IgM responses were observed in 9/299 (3%) individuals. In conclusion, a high IgG seroprevalence of HBoV in the adult population was observed, whereas the presence of virus-specific IgM was associated with viremia. These data show that ELISA test systems for the detection of HBoV-specific antibodies are a valuable tool for serological diagnosis of this new emerging pathogen.

Abstract
Pregnant women who have an urogenital Chlamydia trachomatis infection may transmit the infection to their infants. Conjunctivitis and nasopharyngeal infection are the most frequent manifestations. Less frequently the infants may develop pneumonia. We report a case of a 5-week-old girl with poor feeding, staccato cough and clinical signs of pneumonia. Chest radiography revealed severe bronchopneumonia. Despite of intravenous therapy with ampicillin and gentamicin respiration deteriorated and oxygen supplementation became necessary. After additional treatment with oral erythromycin (50 mg/kg per day) had been started the clinical condition improved. Polymerase chain reaction with a nasopharyngeal specimen was found to be positive for Chlamydia trachomatis.

Abstract
BACKGROUND Recent investigations have reported an influence of thrombophilic mutations and antithrombotic risk factors with development of intraventricular hemorrhage. It was our objective for this study to investigate the impact of genetic polymorphisms of hemostasis genes on the primary outcome measures of sepsis, bronchopulmonary dysplasia, intraventricular hemorrhage, and periventricular leukomalacia in a large cohort of very low birth weight infants. METHODS There were 586 very low birth weight infants enrolled prospectively in a multicenter trial between September 2003 and July 2005, and an additional 595 very low birth weight infants, who had been recruited in a previous prospective trial, were studied. DNA samples were taken by buccal swab, and genotypes of factor V Leiden mutation, prothrombin G20210A mutation, the factor VII-323 del/ins polymorphism, and the factor XIII-Val34Leu polymorphisms were determined by polymerase chain reaction and restriction enzyme digestion. RESULTS In contrast to data published previously, the frequency of intraventricular hemorrhage or periventricular leukomalacia was not significantly influenced by any of the genetic variants tested. Carriers of the factor XIII-Val34Leu polymorphism, however, had a higher sepsis rate and a longer period of hospital care compared with noncarriers. The factor VII-323 del/ins polymorphism was found to be a potential protective factor against bronchopulmonary dysplasia. CONCLUSIONS We could not confirm previously reported associations of hemostasis gene variants and development of intraventricular hemorrhage in very low birth weight infants. To better understand gene-disease associations in very low birth weight infants, the prospective development of large-scale cohorts with well-defined phenotypes and corresponding DNA samples is essential.

Abstract
We investigated the association between the interleukin 6 (IL-6)-174-genotype and unfavorable outcomes in preterm infants since it has been reported that the IL-6-174GG-genotype is associated with increased susceptibility to sepsis, and the IL-6-174CC-genotype is more common in preterm infants with severe intraventricular hemorrhage (IVH). We studied 1206 preterm infants with a birth weight below 1500 g. In contrast to previously published data, the frequency of IVH grade IV, periventricular leukomalacia, ventricular-peritoneal-shunting or death was not different between infants with different IL-6-genotypes: IL-6-174GG (n = 430) 8%, IL-6-174GC (n = 605) 9% and IL-6-174CC (n = 167) 12% (P = 0.2 for IL-6-174CC vs GG + GC). Furthermore, we were not able to confirm previously reported association between sepsis and the IL-6-174GG-genotype. Blood-culture-proven sepsis occurred in 19% of IL-6-174GG-carriers (n = 157), 26% of IL-6-174GC-carriers (n = 193) and 27% of infants carrying the IL-6-174CC-genotype (n = 67). We were not able to confirm previously reported associations between sepsis, cerebral injury and the IL-6-174-genotype in VLBW-infants.

Abstract
An altered inflammatory activity due to functionally relevant polymorphisms of the innate immune system may influence pathways leading to labour and, therefore, impact on the frequency of preterm birth. We examined five polymorphisms of the innate immune system in a large cohort of preterm very-low-birth-weight (VLBW, n = 909) and term-born infants (n = 491) and their mothers (n = 747). The primary outcome was preterm versus term birth. Frequencies of polymorphisms in mothers of term-born infants versus mothers of VLBW infants and term infants versus preterm VLBW infants (singletons) are given. Homozygous CD14-159T: 18.5 versus 21.8% (mothers) and 19.6 versus 21.2% (infants). Homozygous interleukin IL-6-174G: 28.8 versus 38% (P = 0.018, mothers) and 30 versus 32.7% (infants). Homozygous or heterozygous nuclear oligomerization domain NOD2-3020insC: 6.9 versus 6.1% (mothers) and 5.7 versus 5.1% (infants). Heterozygous or homozygous toll-like-receptor TLR2-Arg753Gln: 6.9 versus 6.1% (mothers) and 5.7 versus 5.1% (infants). Homozygous or heterozygous TLR4-896G: 8.1 versus 11.5% (mothers) and 11.6 versus 10.5% (infants). Although the homozygous maternal IL-6-174G genotype was found to be independently associated with preterm delivery in multivariate regression analysis, the incidence of intrauterine infection was not significantly increased in mothers of preterm VLBW-infants, carrying this or other polymorphisms of the innate immune system. The overall influence of the investigated polymorphisms on the development of preterm delivery seems moderate, since only the maternal IL6-174G genotype was associated with preterm birth and none of the polymorphisms were associated with intrauterine infection as the cause of preterm birth.

Abstract
Mutations of genes involved in the innate immune system have been reported to be associated with an increased sepsis rate in adults. We determined the -159T mutation of the CD14 gene, the 896G mutation of the toll-like receptor 4 gene, the 3020insC mutation of the NOD2 gene (NOD2-3020insC), the IL-6 174G/C promoter polymorphism (IL6-174G/C), and the mannose-binding lectin genotype and their association to the subsequent development of neonatal sepsis in a large cohort of very low birth weight (VLBW) infants. Fifty (14%) of 356 VLBW infants developed blood culture-proven sepsis during their stay in the hospital. VLBW infants carrying the NOD2-3020insC allele (n =15) and the IL6-174G allele (n =121) had a significantly higher rate of blood culture-proven sepsis (33% and 19.8%, respectively) than VLBW infants without these genotypes (p = 0.046 and 0.035, respectively). In a multivariate logistic regression analysis, gestational age less than 28 wk (odds ratio, 3.2; 95% confidence interval, 1.7-6.0; p < 0.001) and the homozygous IL6-174G allele (odds ratio, 1.9; 95% confidence interval, 1.0-3.9; p = 0.039) were predictive for the development of sepsis, whereas the NOD2-3020insC allele was only of borderline significance (odds ratio, 3.2; 95% confidence interval, 1.0-10.4; p = 0.052). VLBW infants with repeated episodes of sepsis had higher frequencies of the NOD2-3020insC and IL6-174G allele. The increased sepsis rate of homozygous IL6-174G carriers was especially related to an increase in Gram-positive infections, and was not observed in VLBW infants who received prophylaxis with teicoplanin (frequency of Gram-positive sepsis in homozygous IL6-174G carriers without prophylaxis 16.5% versus 2.4% in homozygous IL6-174G carriers with prophylaxis; p = 0.033).

Abstract
OBJECTIVES The 34Leu polymorphism of the factor XIII gene is associated with a low rate of brain infarction and a higher incidence of primary intracerebral hemorrhage in adults. We evaluated the effect of the polymorphism on the subsequent development of isolated intracranial hemorrhage and white matter disease in preterm infants with a birth weight <1500 g (very low birth weight [VLBW] infants). STUDY DESIGN We studied 531 VLBW infants and 301 control infants born at term. The factor XIII 34Leu polymorphism was detected by polymerase chain reaction and restriction enzyme digestion. RESULTS Allele frequencies were not different from term and VLBW infants (Val/Val, 53.1% and 57.8%; Val/Leu, 38.8% and 37.6%; Leu/Leu, 8.0% and 4.5%, respectively). VLBW infants carrying the Leu/Val or Leu/Leu allele had a significant reduced risk of the development of white matter disease (3.6% vs 10.4% in infants without the polymorphism, P =.003). In a multivariate logistic regression analysis, only gestational age <28 weeks (odds ratio, 3.8; 95% confidence interval, 1.9-7.5; P <.001), and the factor XIII 34Leu allele (odds ratio, 0.3; 95% confidence interval, 0.1-0.7; P =.005) had significant prognostic value in predicting subsequent white matter disease. However, VLBW infants who carried the factor XIII 34Leu allele also had a moderately increased risk of the subsequent development of isolated intraventricular hemorrhage (14.3% vs 10.1% in infants without the mutation, P =.17). CONCLUSIONS VLBW infants carrying the factor XIII 34Leu polymorphism had a decreased risk for white matter disorders.

Abstract
BACKGROUND AND OBJECTIVE To prospectively survey skin lesions in a large group of newborns, as no such study has as yet been performed in Germany. PATIENTS/METHODS In a prospective study, we examined one thousand newborn babies twelve to 120 hours old. RESULTS In 59.7%, one or more skin lesions could be detected, some of which were only transient. Noticeable differences from other studies included a higher incidence of congenital melanocytic nevi (6%) and port wine stains (2.8%). Instead of the usual male:female ratio of 1:2 we found a 1:1 ratio for port wine stains. Toxic erythema of the newborn and milia were less frequent than in other studies. CONCLUSIONS With a frequency of 37.2%, vascular lesions such as nevus flammeus and hemangioma are the most common skin lesions in newborns. Our study found a higher incidence of congenital melanocytic nevi than reported in literature. An associated of skin lesions and maternal smoking during pregnancy was not detected.

Abstract
Fibroblast growth factor receptor 3 (FGFR3) is a glycoprotein that belongs to the family of tyrosine kinase receptors. Specific mutations in the FGFR3 gene are associated with autosomal dominant human skeletal disorders such as hypochondroplasia, achondroplasia, and thanatophoric dysplasia. Hypochondroplasia (HCH), the mildest form of this group of short-limbed dwarfism disorders, results in approximately 60% of cases from a mutation in the intracellular FGFR3-tyrosine kinase domain. The remaining cases may either be caused by defects in other FGFR gene regions or other yet unidentified genes. We describe a novel HCH mutation, the first found outside the common mutation hot spot of this condition. This point mutation, an N328I exchange in the extracellular Ig domain III of the receptor, seems to be unique as it affects a putative N-glycosylation site that is conserved between different FGFRs and species. The amino acid exchange itself most probably has no impact on the three-dimensional structure of the receptor domain, suggesting that the phenotype is the result of altered receptor glycosylation and its pathophysiological consequences.

Abstract
A 9 1/2-year-old girl suffered from intermitting tremor and jitteriness of her left hand and oral muscles every 4 to 6 weeks with long lasting episodes. Clinically myoclonias and dystonic positioning of the left arm, hand and facial muscles were seen. No evidence of trauma, infection or inborn errors of metabolism was found. Successful therapy with carbamazepine was initiated while L-DOPA failed. An ictal 99m-Tc-HMPAO-SPECT showed severe asymmetry with focal hyperperfusion of the contralateral right thalamus and basal ganglia as well as of the bifrontal cortex, whereas no anatomical lesions were found by MRI. In contrast, an interictally performed 99m-Tc-HMPAO SPECT showed hypoperfusion of the right thalamus and normalisation of the frontal perfusion under medical treatment. These 99m-Tc-HMPAO-SPECT findings may provide new insights into the localisation and pathophysiological pathways of idiopathic childhood dystonia.

Abstract
Following surfactant instillation in infants treated for respiratory distress syndrome, a mean arterial blood pressure (MABP) decrease is often observed. Its etiology and pathogenesis are still unknown. In this study various circulatory parameters were recorded continuously after surfactant instillation to elucidate the role of pulmonary vascular resistance as one possible cause for the MABP drop. Seven anesthetized adult New Zealand white rabbits were artificially ventilated after tracheotomy. Arterial and right atrial pressure were recorded continuously. Pulmonary artery pressure and cardiac output were determined by means of a thermodilution catheter. After inducing surfactant deficiency by repeated saline lavages, 200 mg/kg body weight of a natural surfactant preparation was administered by tracheal bolus instillation. PaO2 increased rapidly from 8.0 +/- 1.3 kPa to 51.2 +/- 8.8 kPa (mean +/- standard deviation) within 2 min (p < .05). MABP dropped from 12.1 +/- 1.9 kPa to 8.9 +/- 2.3 kPa within 2 min (p < .05). Pulmonary artery pressure, cardiac output, and right atrial pressure did not change during the observation period of 60 min. The results suggest that a peripheral vasodilatation is the most likely cause for the drop in MABP.

Abstract
UNLABELLED Surfactant bolus instillation may be associated with a drop in blood pressure. Platelet-activating factor (PAF) has been found in surfactant preparations. The aim of this study was to evaluate rapid tracheal infusion of surfactant during 5 min as an alternative to bolus instillation and to examine whether a PAF receptor antagonist is able to prevent the decrease in blood pressure. METHODS Surfactant deficiency was induced in 16 adult rabbits by lung lavages with saline. Six animals received a bolus of a porcine surfactant preparation (Curosurf (CS); 200 mg/kg), labeled with red microspheres to assess pulmonary distribution. In another 5 rabbits, the same amount of labelled CS was instilled by tracheal infusion within 5 min. A third group of 5 animals received 3 mg/kg body weight of the PAF antagonist WEB 2170 before CS bolus instillation. RESULTS After CS bolus administration, mean PaO2 increased by 44.7 +/- 8.3 kPa (mean +/- SD) within 2 min and remained at this level. Mean arterial blood pressure dropped transiently by 2.3 +/- 2 kPa within 5 min. Pulmonary distribution of surfactant was even. After infusion, mean PaO2 rose by 22.4 +/- 16.3 kPa within 15 min. Blood pressure dropped by 1.8 +/- 1.1 kPa within 15 min. The distribution was extremely uneven. Blood pressure decreases also occurred after pretreatment with PAF receptor antagonist. CONCLUSION Rapid tracheal infusion of surfactant results in poorer oxygenation, an inhomogeneous distribution and a similar decrease in blood pressure compared to the bolus instillation method. Blood pressure changes could not be prevented by a PAF receptor-specific antagonist.

Abstract
Fifteen preterm infants suffering from respiratory distress syndrome were randomly allocated to receive either high-dose (200 mg/kg) or low-dose (100 mg/kg) surfactant treatment. Retreatments were done with the low dose. Blood pressure, blood gases and cerebral blood flow velocities were determined before and after 24 bolus instillations. With the high dose mean blood pressure and mean cerebral blood flow velocity dropped significantly. With the low dose only mean cerebral blood flow velocity decreased; the course was unrelated to blood pressure or PCO2 fluctuations. The mechanisms leading to the observed circulatory changes after surfactant instillation remain unclear.

Abstract
Surfactant bolus instillation has been reported to cause changes in arterial blood pressure (BP) and cerebral blood flow velocities which may increase the risk of intraventricular haemorrhage. To avoid these effects, slow tracheal infusion was evaluated as a possible alternative method of surfactant administration. Saline lung lavages were performed in 13 anesthetized and artificially ventilated adult rabbits to produce respiratory distress syndrome. Curosurf (CS, 200 mg/kg) labeled with 14C-dipalmitoyl-phosphatidylcholine (-DPPC) and/or red microspheres (RMS) was instilled into the trachea either as a single bolus (n = 8) or by infusion during 45 min via a side-channel within the wall of the tracheal tube (n = 5). An arterial cannula was placed for monitoring of blood gases and BP. To determine surfactant distribution, the lungs were cut into 60-70 pieces and radioactivity and/or the number of RMS were measured in each piece. The distribution of RMS was closely related to the distribution of 14C-DPPC (r = 0.96). Bolus instillation of CS led to a prompt and sustained increase in PaO2 (from < 10.5 to > 40 kPa within 2 min), a transient decrease in BP, and a reasonably homogeneous pulmonary surfactant distribution. Tracheal infusion of CS changed neither BP nor PaO2 during the observation period of 60 min. The pulmonary distribution of CS was extremely uneven after infusion. The distribution of exogenous surfactant and its effects on gas exchange are influenced by the instillation method. An inadequate instillation technique may add to the causes of "poor response" after surfactant replacement.
