Aim: To investigate risk factors of adverse outcome in a cohort of very preterm children treated mainly with nasal continuous positive airway pressure (CPAP) during the neonatal course.Methods: In Denmark, preterm children are treated with nasal CPAP as a first approach to respiratory support. A national prospective study of all infants with a birthweight below 1000 g or a gestational age below 28 wk born in 1994-1995 was initiated to evaluate this approach. Of the 269 surviving children 164 (61%) were not treated with mechanical ventilation in the neonatal period. A follow-up of the children at 5 y of age was conducted. Data from the neonatal period and the 5-y follow-up were analysed.Results: In multivariate analyses including 250 children, a severely abnormal neonatal brain ultrasound scan was predictive of cerebral palsy (OR = 19.9, CI 95%: 6.1-64.8) and intellectual disability (OR = 6.2, CI 95%: 2.3-16.5). A high Clinical Risk Index for Babies (CRIB) score (OR = 2.4, CI 95%: 1.1-5.5) and chronic lung disease (OR = 2.8, CI 95%: 1.2-6.9) were predictive of intellectual disability. In univariate analyses mechanical ventilation was associated with cerebral palsy (OR=4.3, CI 95%: 1.7-10.8) and intellectual disability (OR = 2.2, CI 95%: 1.2-4.2), but the associations became insignificant in multivariate analyses including chronic lung disease and a severely abnormal ultrasound scan.Conclusion: The associations between neonatal risk factors and adverse outcome in our cohort were very similar to those found in other cohorts with another initial treatment of respiratory insufficiency. We found no significant adverse effects of mechanical ventilation beyond what could be explained by associations with chronic lung disease and IVH 3-4/PVL. [ABSTRACT FROM AUTHOR]

Background: The best method for prevention and control of congenital toxoplasma infection is uncertain. Prenatal screening is done in Austria and France, but the effect of treatment during pregnancy is not well documented. The aim of our study was to find out the maternofetal transmission rate and outcome in infants born to mothers who were not treated during pregnancy.Methods: We analysed 89873 eluates from phenylketonuria (PKU) cards from neonates and paired first-trimester serum samples from the mothers for specific IgG antibodies to Toxoplasma gondii. Children born to mothers who seroconverted during pregnancy were followed-up clinically and serologically to 12 months of age. In addition, 21144 PKU cards were analysed for toxoplasma-specific IgM antibodies during the last 12 months of the study.Findings: In 24989 (27.8%) cases both the PKU eluate and the first-trimester samples were IgG positive, which indicates previous maternal infection. 139 of the 64884 seronegative women acquired toxoplasma infection during pregnancy and gave birth to 141 infants (two sets of twins). 27 of these children were diagnosed with congenital toxoplasma infection. The transmission rate was 19.4% (95% CI 13.2-27.0). Clinical signs and symptoms were found in four (15%) of the 27 children. The additional analysis for toxoplasma-specific IgM antibodies from the PKU card identified seven of nine children with congenital toxoplasma infection. The false-positive rate for the IgM test was 0.19 per 1000, and no false-negatives were found.Interpretation: The risks of transmission of infection and of disease in the infant are low in an area with a low risk of toxoplasma infection. A neonatal screening programme based on detection of toxoplasma-specific IgM antibodies alone will identify between 70% and 80% of cases of congenital toxoplasmosis. [ABSTRACT FROM AUTHOR]

The aim was to study how, and to what degree, health-related quality of life (HRQOL), as assessed by children and their mothers, was related to overweight and obesity among children aged seven to nine years. Mother-child pairs of 149 non-overweight, 95 overweight and 16 obese children participated. We assessed HRQOL by the children's self-report and parent proxy report module of the PedsQL™ 4.0 Generic Core Scales. We found that non-overweight children scored HRQOL slightly higher than overweight ones but significantly higher than did obese children. The same pattern was seen for the mothers' proxy HRQOL score and mothers in general scored higher than the children did. The results indicate that mothers in general were not sufficiently aware of how overweight and obesity affect their children's HRQOL. The psychosocial dimension of HRQOL was the most important aspect for the children. Thus, there is a need for information of mothers/parents about the impact of overweight and obesity on children's HRQOL. Such intervention by health professionals may among other interventions help to prevent and reduce overweight and obesity among children and thus help to increase the children's HRQOL throughout their lives., (© The Author(s) 2014.)

This qualitative phenomenological study interviewed seven mothers to overweight children and six mothers to non-overweight children aged 7 to 9 years old about their views and experiences with preventing and managing overweight in their children. The essence was that the mothers felt responsible for their children's habits, including those leading to overweight. They also felt that competent and had the opportunity to take preventive measures against child overweight but they did not always have the energy to do so. Even resourceful mothers required support from nurses and health professionals. Our results contribute to better understanding how to approach, motivate and support mothers to draw on their own competencies to benefit their children's weight and health., (Copyright © 2013 Elsevier Inc.

Objective: We investigated mothers' and children's assessments of body weight and their expectations about perceived body size in relation to overweight of the children., Methods: We performed a case-control study of 111 cases of overweight children and 149 controls of non-overweight children (mean age 8.1 years) and their mothers. All were examined and interviewed about their assessment of body weight and their perception of a normal, attractive and acceptable body size., Results: Case children were less able than control children to correctly assess their own body weight (p < 0.001), as were mothers of overweight children (MOC) to assess their children's body weight (p < 0.001). The majority of mothers from both groups wished their children to have a normal body size, but 18% of MOC wished their children to have an overweight body size (p < 0.013). The majority of case children, control children and mothers found a normal body size for boys and girls to be the most attractive and socially acceptable, but more MOC found overweight among boys to be the most attractive (p = 0.006)., Conclusion: Overweight children and their mothers show increased uncertainty in the assessment of overweight and obesity, but the perception of a normal, attractive and socially acceptable body size is not distorted., (Copyright © 2011 S.

Objective: We investigated mothers' possession and display of action competence to counteract or prevent overweight and eventual obesity in their children. Action competence is defined as a personal resource where the most important aspect is the individual's wish to take action and to believe in its benefit. It unfolds within the room for action as experienced by the individual due to action obstacles and action potentials., Methods: In a case-control study, mothers of 111 overweight children (MOC) were compared with mothers of 149 non-overweight children (MNC). They underwent a semistructured interview about action competence, lifestyle, and their 7- to 9-year-old children., Results: Compared to MNC, MOC considered it more important to change habits, both for themselves (p = 0.003) and their children (p < 0.001). MOC were more motivated to change habits (p < 0.001), assessed their action competence to be higher (p < 0.001), and felt to a greater extent that they supported their children to achieve an appropriate weight (p < 0.001) compared with MNC. No difference was found between MOC and MNC in the assessment of their own room for action and their children's room for action., Conclusion: Self-assessed room for action was not limited for either MOC or MNC, and MOC even assessed their action competence to be greater., (Copyright © 2011 S.

Autoimmune polyglandular syndrome (APS) is an entity, defined by autoimmunity towards two or more endocrine organs. APS is classified in 3 subgroups (type-1, type-2a, type-2b), according to the organs involved. A case is presented of a 13-year old girl referred to the Department of Paediatrics with hypothyroidism, subsequently diagnosed adrenocortical insufficiency and impending Addison crisis, typical for APS-type 2a. In the paper we discuss the need for more attention to APS in clinical work.

Today there are 19 paediatric departments in Denmark. Most of the children's departments are placed in obsolete buildings. Centralisation in children's hospital provides a child-oriented environment with staff, who are knowledgeable about the needs of children, have the competence in both basic and highly specialised medical care, there will be greater opportunities to conduct research in children's diseases and be at the cutting-edge of both national and international excellence in the paediatric area of specialisation, accomplishing this ambition through research and medical improvements.

The prevalence of hepatitis B virus (HBV) carriage in Denmark is unknown, but expected to be low (0.1%). This study aimed to evaluate the efficacy of selective antenatal screening for HBV infection and the epidemiology of HBV and hepatitis C virus (HCV) among pregnant women. 4098 women were included in the study. Blood tests were examined for hepatitis B surface antigen (HBsAg), anti-hepatitis B core antigen (HBc) and anti-HCV. Case records were studied to evaluate whether patients at risk for HBV infection had been tested. Among the 4098 women, 18 10.4%, 95% confidence interval (95% CI) 0.3-0.71 were HBsAg positive. All had a risk factor for HBV infection. Only 13 (72%) were identified as HBsAg positive in the selective screening programme. 115 women (2.8%, 95% CI 2.3-3.4) were anti-HBc positive only. 95 (83%) were at risk for HBV. Only 72 of these (63%) were tested for HBsAg. The screening programme in this area of Denmark did not pick up one-third of pregnant women at risk of HBV.

Introduction: Beta-thalassemia major occurs with increasing frequency among Danish children as a result of immigration. The aim of the study was to estimate the occurrence of beta-thalassemia major in Denmark, analyse the treatment and organ functions, and identify areas for an improved treatment strategy., Material and Methods: During 1998-99 all Danish pediatric departments were contacted for identification of children aged 0-18 years with beta-thalassemia major. Blood transfusions and chelation therapy were registered, and for Eastern Denmark clinical, endocrine, cardiac, and serologic parameters were performed., Results: Twenty-six children had beta-thalassemia major. Out of these, 20 received blood transfusions, and 17 patients were chelated. Eight patients were not chelated owing to previous bone marrow transplantation, treatment with hydroxyurea or ferritin < 2000 micrograms/l and young age. One patient had died. The body height was between 1.5 and -5.4 SDS (median -1.7) and the sitting height was -0.6 to -5.6 SDS (median -2.3). The bone age was delayed 1-5 years (median -2.5) in six out of ten examined patients, and puberty delayed in four out of five. A dilated left ventricle was documented in one out of eight patients examined. All patients were HIV and hepatitis C negative. For 75% of the children, the parents were related., Discussion: Children and adolescents with beta-thalassemia major in Denmark experience major heterogenicity with regard to treatment and late effects. An earlier and more effective iron chelation therapy together with improved patient support may reduce growth disturbances and endocrine and cardiac late effects.

Unlabelled: Premature infants require large amounts of protein and energy to achieve normal growth. Feeding with human milk alone is therefore only regarded acceptable if the protein and energy content is adequate., Methods: 476 milk samples from 101 mothers delivering before the 32nd gestational week (mean gestational age, 28 weeks) were obtained on a weekly basis until 36 weeks of gestational age and analyzed for true protein, total carbohydrate, and fat content by infrared analysis. Fat measurements were validated with the Folch method. Milk was collected by complete expression with an electric pump into 24-hour pools., Results: The protein concentration decreased significantly with time (P = 0.00001). The carbohydrate, fat, and energy concentration was significantly lower in the first 2 weeks after delivery, after which they increased to a constant level. The macronutrient level in milk was not associated with gestational age (P = 0.3). The energy content of these milk samples was high, and feeding 200 mL/kg would provide sufficient energy until 36 weeks of gestational age for all infants, and 65% of the infants would receive > or =3g total protein/kg/day.

Energy, protein, and mineral requirements in premature infants are high, hence increasing the risk of poor growth and development of metabolic bone disease. This double-blind study included 127 consecutive premature infants with gestational age below 32 weeks. Both sick and healthy infants participated. Average duration of ventilator treatment: 2 days, CPAP treatment: 10 days (range, 0-50d). Infants were randomized to 3 groups from 1 week old to 37 weeks of gestational age and fed the following: a) human milk (their own mother's milk or banked milk) supplemented with phosphate, b) human milk fortified with protein, calcium, and phosphate, or c) unsupplemented mother's milk or preterm formula. Infants randomized to preterm formula were fed formula only if their own mother's milk was not available, hence there were 2 subgroups of infants fed either unsupplemented human milk or preterm formula. Volume of intake was 191+/-14mL/kg/d (mean +/- SD); linear growth was measured weekly by knemometry; head circumference was measured weekly; and growth rate was calculated by linear regression for each infant. Bone mineralization and body composition were measured by DEXA-scan (Hologic 1000/W) at term. There was a tendency toward slower growth and less bone mineral content in infants fed unsupplemented human milk but, surprisingly, the difference was small and not significant.

The aim of the study was to evaluate the benefit from participation in parent groups for parents of extremely premature new-born babies. The participation in the parent groups led by the psychologist took place during the hospitalization of the child on the neonatal ward. All parents of extremely premature new-borns admitted to the neonatal department, Hvidovre Hospital, Copenhagen, Denmark in the period from 1 January 1992 to 30 June 1994, were asked to fill in questionnaires. The study population comprised the parents of 58 children. The parents of 14 children did not want to participate. Of the remaining 44 children, 36 were alive and eight had died at the time of the study. Most parents participated in the parent group and the majority stated they had benefited from the participation. It is therefore considered a relevant psychological task to establish parent groups for parents of extremely premature new-borns as a mean of crisis intervention in the neonatal department.

Premature infants are at risk of developing metabolic bone disease mainly because of low calcium and phosphorus intake. We have examined the effect of different mineral supplements on bone mineral content at term in 127 premature infants with gestational age <32 wk in a double-blinded randomized trial. We used either phosphate supplementation of human milk as recommended by the European Society of Pediatric Gastroenterology and Nutrition or fortified supplementation with protein, calcium, and phosphorus or preterm formula as recommended by the American Academy of Pediatrics. The intervention period was from 1 week old until 36 wk of gestational age, and the infants were fed approximately 200 mL x kg(-1) x d(-1). Bone mineral content was measured at term by dual-energy x-ray absorptiometry scan. Surprisingly, neither phosphate, fortifier, nor preterm formula supplementation had any significant effect on bone mineral content at term compared with infants fed their own mother's milk only. There was a tendency to higher total bone mineral content in infants fed preterm formula compared with infants fed their own mother's milk only (p = 0.05), but when the bone mineral content was corrected for the size of the infant, there was no difference (p = 0.68). Infants fed preterm formula had a significantly higher weight at term compared with infants fed their own mother's milk only (p = 0.02), but did not differ significantly in length or head circumference. In a regression analysis, the amount of supplemented phosphorus was significantly associated with weight at term (p = 0.008). We conclude that when feeding 200 mL x kg(-1) x d(-1), mineral supplementation of human milk or use of preterm formula does not significantly improve bone mineralization outcome at term.

The purpose of this study was to determine whether visual stimulation in sleeping infants and young children can be examined by functional magnetic resonance imaging. We studied 17 children, aged 3 d to 48 mo, and three healthy adults. Visual stimulation was performed with 8-Hz flickering light through the sleeping childs' closed eyelids. Functional magnetic resonance imaging was performed with a gradient echoplanar sequence in a l.5-T magnetic resonance scanner. Six subjects were excluded because of movement artifacts; the youngest infant showed no response. In 10 children, we could demonstrate areas of signal decrease during visual stimulation in the occipital cortex (mean decrease 2.21%), contrary to the signal increase observed in the adult controls (mean increase 2.82%). This decrease may be due to a higher proportional increase in oxygen extraction compared with increase in cerebral blood flow during activation. The different response patterns in young children and adults can reflect developmental or behavioral differences. Localization of the activation seemed to be age-dependent. In the older children and the adults, it encompassed the whole length of the calcarine sulcus, whereas it was restricted to the anterior and medial part of the calcarine sulcus in the younger infants. This may reflect a different functional organization of the young child's visual cortex or the on-going retinal development.

The aim of this study was to evaluate the attitude among parents of extremely premature newborn children towards fixed lower limits for treatment and towards parent involvement in decisions about the treatment of their child. All parents with extremely premature newborns admitted from January 1, 1992 to June 30, 1994 to the Neonatal Department, Hvidovre Hospital, Copenhagen, Denmark, were asked to fill in questionnaires. The study population comprised the parents of 58 children. The parents of 14 children did not want to participate. Of the remaining 44, 36 children were alive and eight had died at the time of the study. Almost all parents stated that neither birth weight nor gestational age were acceptable as criteria for treatment or non-treatment of premature newborns. This attitude contrasted with the recommendation in 1994 from The Danish Council of Ethics. Half of the parents expressed a wish to be involved in the decisions about the treatment of their newborn child. This attitude agreed with the recommendation from the Danish Council of Ethics.

To investigate the metabolic consequences of germinal matrix hemorrhage (GMH) we used volume-selective 1H magnetic resonance spectroscopy in the striatal region in 12 preterm infants with predominantly small GMH. Both sides of the brain were investigated twice. Metabolite indices were calculated as the metabolite signal, recorded with TR = 1.6 s and TE = 272 ms, divided by the fully relaxed water signal corrected for transverse relaxation time constant (T2) decay. At the first investigation, when the infants were 32.5 +/- 2.0 (mean +/- SD) wk postmenstrual age, the hemorrhage was unilateral or markedly asymmetrical in size in 10 of 12 infants. The lactate index was higher (p < 0.01) and the phosphocreatine + creatine (Cr) (p < 0.05) and N-acetyl-L-aspartate (NAA) (p < 0.05) indices lower in the side with the larger hemorrhage. At the second investigation, 54.1 +/- 2.7 wk postmenstrual age, no sign of a previous GMH could be seen on magnetic resonance imaging in three of 10 infants. Lactate could be detected in two of 10 infants only, and the Cr and NAA indices did not differ between sides. However, the choline index was significantly higher in the side with the larger hemorrhage (p < 0.01). We conclude that GMH is initially followed by lactate accumulation and possibly a delay in maturation as indicated by the transiently low Cr and NAA indices. Moreover, an increased choline index at the corrected age of 3 mo indicates a more persistent metabolic change after small GMH.

Purpose: The purpose was to obtain normal values of the apparent diffusion coefficient (ADC) in the infant brain and to compare ADC maps with T1- and T2-weighted images., Method: Diffusion was measured in nine infants with an ECG-gated SE sequence compensated for first-order motion. One axial slice at the basal ganglia level was investigated with the diffusion-encoding gradients in the slice-selection direction., Results: On ADC maps, the corpus callosum and the optic radiations appeared dark before the onset of myelination, and the crus posterior of the internal capsule could be visualized before it appeared on T1- or T2-weighted images. In gray and white matter, the mean ADC ranged from 0.95 x 10(-9) to 1.76 x 10(-9) m2/s. In the frontal and occipital white matter, in the genu corporis callosi, and in the lentiform nucleus, the ADC decreased with increasing age. The cortex/white matter ratio of the ADC increased with age and approached 1 at the age of 30 weeks., Conclusion: ADC maps add information to the T1 and T2 images about the size and course of unmyelinated as well as myelinated tracts in the immature brain.

Twenty-eight infants with postmenstrual ages (PMA) in the range of 32-80 weeks were investigated. Twenty were newborn; among these the observed birth weight divided by the expected weight ranged from 0.31 to 1.1. Axial magnetic resonance images were recorded with a triple spin-echo sequence and the volumes were determined by encircling each structure of interest on every slice. Segmentation into grey matter, white matter and CSF was done by semi-automatic discriminant analysis. Growth charts for the cerebrum, cerebellum, corpora striata, thalami, ventricles, and grey and white matter are provided for infants with appropriate birth weight. The striatal (P = 0.02) and thalamic (P < 0.001) percentage of the hemispheric volume decreased with age, whereas the ratio of grey matter to white matter (G/W-ratio) increased (P = 0.01). In the neonatal patients, brain volumes were independently associated with both PMA and the degree of growth retardation. It was calculated that the hemispheric volume was reduced by from 16% to 23% if the total bodyweight was reduced by 40%. The G/W-ratio was found to be independently associated with the PMA (P < 0.05) and the degree of IUGR (P < 0.1) suggesting that fetal growth retardation reduces grey matter volume more than white matter.

The AIDS-committee of The Danish Society of Paediatrics has done a nation-wide study among infants and children under the age of 15 with AIDS or HIV-antibodies in preparation for planning prevention and treatment. Clinical data have been collected from the Departments of Paediatrics and Infectious Diseases, Haemophilia, Dermatology and Internal Medicine up to 1 March 1993. The study includes 44 infants with a risk of vertical transmission from the mother and 16 children with haemophilia. No cases were found to be infected by blood-transfusion. Twenty of the 44 infants with congenital HIV-antibodies were HIV-infected. Seven of them died from AIDS, 10 currently have AIDS and three are asymptomatic. Seventeen infants are well and HIV-antibody negative after the age of 18 months. Seven infants still have unclarified status, but all are well. Three of the patients with haemophilia are dead. The 13 others do not have AIDS. It is surprising that most of the infected infants' mothers were not known to be infected before the infants got sick. Thus infected infants exist in families who are not suspected to be HIV-infected. The AIDS-committee of The Danish Society of Paediatrics has proposed recommendations for HIV-testing of infants and children. HIV-infected families need comprehensive psychosocial care. The risk-factor from blood-transfusion is now eliminated, but vertical transmission will continue to be a risk-factor. The size of the problem in Denmark will not be known until an epidemiological study of pregnant women has been conducted.

In the period 1985 to 1991, 80 infants with gestational age below 28 completed weeks were born at Hvidovre Hospital, Copenhagen and transferred to the neonatal intensive care unit of the hospital. The incidence of extreme prematurity was 3.6 0/00. Twenty-eight infants died during the neonatal period (35%) and nine infants died later in infancy (11.3%). Forty-three infants (54%) survived. Forty four percent of surviving infants had one or more sequelae related to their prematurity or neonatal complications, mainly blindness or reduced vision, cerebral palsy and mental retardation. Neither gender, mode of delivery or birth asphyxia were important for survival and sequels. Neonatal complications such as patent ductus arteriosus, septicaemia, necrotizing enterocolitis, pneumothorax and cerebral haemorrhages were significantly related to survival and sequelae.

In a retrospective study, all deliveries at Hvidovre Hospital, Copenhagen, with birth weights < or = 1500 g and gestational ages of 23 to 32 completed weeks were examined to find out how they were recorded and the survival of the baby. Sixty-one were registered as abortions, 151 as births. Sixteen infants (10.2%) were registered as stillborn and 9 (6.7%) were live born without major malformations but died in the delivery ward without transfer to the neonatal intensive care unit (NICU) of the hospital. The survival for infants without severe malformations was 72.4% for all liveborn infants, and 77.6% for infants transferred to the NICU. The youngest surviving infant was born after 24 completed weeks of gestation. Because of different criteria for selection, comparison between different studies is difficult. This investigation shows that registration of very premature deliveries can be heterogenous. This is of great importance for survival and outcome rates because of the small number of very premature infants. We suggest a registration of all deliveries taking place after 22 completed weeks of gestation including birth weight, gestational age, pulse, respiratory movements, lethal malformations and time of death to ensure a better knowledge of the prognosis of these tiny infants.

During the 7 year period 1985 to 1991, 170 infants born in Hvidovre Hospital, Denmark, with birthweight < or = 1500 g and gestational age < or = 32 completed weeks survived at least 8 weeks or more and had eye examinations carried out. Forty-five infants had ophthalmoscopic evidence of retinopathy of prematurity (ROP). Eighteen developed blindness or severely reduced vision and 6 developed unilateral blindness. In 21 the ROP changes regressed. Eight infants eventually developed severe myopia. The 45 infants with ROP were compared with the 125 without ROP. There was no difference in birth weight, gender, or mode of delivery. Significant difference was found in gestational age, asphyxia, intensive treatment and complications. Particularly infants with ROP born with gestational age 27 to 29 weeks needed prolonged and more intensive treatment than infants without ROP. Infants with ROP had more frequently long term sequels from the central nervous system than infants without ROP.
