Selected AbstractsInconclusive Cystic Fibrosis neonatal screening results: long-term psychosocial effects on parentsACTA PAEDIATRICA, Issue 12 2009Sandra Perobelli Abstract Aim:, Cystic Fibrosis (CF) Newborn Screening occasionally identifies neonates where a CF diagnosis can neither be confirmed nor excluded. To assess how parents of these infants cope with this ambiguous situation. Methods:, Parents of 11 children with Ambiguous Diagnosis (group AD) were compared with parents of 11 children diagnosed with CF through neonatal screening [group Cystic Fibrosis Diagnosis (CFD)] and with parents of 11 Healthy Control children (group HC) matched for gender and age. Results:, The emotional reaction to the inconclusive result was less pronounced in AD than in CFD (p = 0.003), and AD parents considered their infants as healthy as controls. Parents' anxiety about their child's health is stronger in CFD than in AD (p < 0.05) and HC (p < 0.001). Long-term emotional distress was rated similarly in AD and CFD, and greater than in HC (p = 0.0003). The parent/child relationship was less influenced in AD than in the CF group (p = 0.03). Seven AD and CFD parents changed their family planning projects. Conclusion:, Inconclusive neonatal screening results appear to be understood and associated with lower anxiety levels than CF diagnosis. Concern about the child's health is similar to healthy controls and lower than in parents of CF children. [source] Development of pro, and antisaccades in children with attention,deficit hyperactivity disorder (ADHD) and healthy controlsPSYCHOPHYSIOLOGY, Issue 1 2003C. H. Klein To date, the investigation of the antisaccade task, a simple test of "executive functions," in children with ADHD has yielded inconsistent results. The present study aimed at contributing to this issue by (a) the investigation of a large sample of carefully diagnosed ADHD patients aged 7,15 years, and (b) the analyses of differential age effects in patients and controls. Healthy control children were pairwise matched with patients (N=46; age=136±24 months) for age and gender, and did not significantly differ in IQ. Horizontal pro, and antisaccades were elicited under the 200,ms gap and overlap conditions (blocks of 100 trials each). Overall, patients exhibited (a) augmented pro, and antisaccadic reaction times, (b) augmented error rates (antitasks), (c) augmented proportions of early responses (all conditions), and (d) reduced proportions of express saccades under the prosaccadic gap condition. The greater decline in anti, as compared to pro,SRT with increasing age that characterized controls was missing in patients. Confirming Barkley's (1997) neuropsychological theory of ADHD, these results altogether point to alterations in "executive Functions" in ADHD patients that are presumably supported by frontal lobe structures, in particular the lateral prefrontal cortex and the frontal eye fields. [source] Academic performance in children with rolandic epilepsyDEVELOPMENTAL MEDICINE & CHILD NEUROLOGY, Issue 5 2008P Piccinelli MD The aim of this study was to investigate the frequency of reading, writing, and calculation disabilities in children with typical rolandic epilepsy (RE) and healthy control children. We also aimed to define the possible electroclinical markers of specific cognitive dysfunctions in RE. School abilities were evaluated and compared in 20 children (eight males, 12 females; mean age 10y 3mo [SD 1y 7mo]; range 7y 9mo-12y 9mo) consecutively diagnosed with typical RE, and a group of 21 healthy controls (nine males, 12 females; mean age 10y 4mo [SD 1y 8mo]; range 7y 6mo-13y 3mo). All the children received standardized neuropsychological tests. For each patient an exhaustive seizure diary was kept and all the sleep electroencephalogram (EEG) recordings were reviewed. Specific difficulties with reading, writing, and calculation (diagnosed according to the criteria of the Diagnostic and Statistical Manual of Mental Disorders, 4th edition) were found in nine out of 20 children with RE and two out of 21 healthy controls (,2=0.01). The specific learning disabilities in the RE group were correlated with a marked increase in epileptiform discharges during sleep (,2=0.02) and an early onset of epilepsy (,2=0.02). Our findings suggest that seizure onset before age 8 years and epileptiform discharges (more than 50% of the sleep EEG recording) in several tracings over more than a year are relevant markers for identifying patients at risk of developing academic difficulties. [source] Oral health in preschool children with asthmaINTERNATIONAL JOURNAL OF PAEDIATRIC DENTISTRY, Issue 4 2008MALIN STENSSON Objective., The aim of this study was to investigate oral health and its determinants in 3-year-old and 6-year-old children with asthma. Methods and subjects., Caries and gingivitis were examined in 127 asthmatic (all children with asthma in a selected area and born during a specific time period) and 117 matched, healthy control children. The parents were interviewed regarding various oral-health-related factors. Results., The mean dfs (± standard deviation) in the 3-year-old with asthma was 1.4 ± 3.2 compared with 0.5 ± 1.2 in the controls (P < 0.05). The corresponding figures for the 6-year-old were 2.5 ± 3.9 and 1.8 ± 2.8. The 3-year-old asthmatic children had more gingival bleeding than the healthy controls (P < 0.05). There were no significant differences in gingivitis in the 6-year-old children. Asthmatic children reported higher consumption of sugar-containing drinks and were more frequently mouthbreathers than healthy children (P < 0.05). In 3-year-old children with asthma and immigrant background, the mean dfs was higher compared with immigrant children in the control group (P < 0.01). Conclusion., The results indicate that preschool children with asthma have higher caries prevalence than healthy children. The factors discriminating for caries in asthmatic children are higher intake of sugary drinks, mouth breathing, and immigrant background. [source] Gene expression profiling in neutrophils from children with polyarticular juvenile idiopathic arthritisARTHRITIS & RHEUMATISM, Issue 5 2009James N. Jarvis Objective We have previously reported a defect in neutrophil activation in children with polyarticular juvenile idiopathic arthritis (JIA). The current study was undertaken to determine whether gene expression abnormalities persist in JIA in remission and to use systems biology analysis to elucidate pathologic pathways in polyarticular JIA. Methods We performed gene expression profiling on neutrophils from children with polyarticular JIA. Children were grouped according to disease status. We studied 14 children with active disease who were taking medication, 8 children with clinical remission of disease who were taking medication (CRM status), and 6 children with clinical remission of disease who were not taking medication (CR status). We also studied 13 healthy children whose age ranges overlapped those of the patients. Results Neutrophil abnormalities persisted in children with polyarticular JIA even after disease remission was achieved. Children with active disease and those with CRM status showed no differences in expression of specific genes, although they could be separated on cluster analysis. A comparison of children with CR status and healthy control children revealed networks of pro- and antiinflammatory genes that suggested that remission is a state of homeostasis and balance rather than a return to normal immune function. Furthermore, gene overexpression in patients with CR status supports the hypothesis that neutrophils play a role in regulating adaptive immunity in this disease. Conclusion Neutrophil gene profiling in polyarticular JIA suggests important roles for neutrophils in disease pathogenesis. These findings suggest the presence of complex interactions between innate and adaptive immunity, that are not easily modeled in conventional, linear, reductionist systems. [source] The meaning of clinical remission in polyarticular juvenile idiopathic arthritis: Gene expression profiling in peripheral blood mononuclear cells identifies distinct disease statesARTHRITIS & RHEUMATISM, Issue 3 2009Nicholas Knowlton Objective The development of biomarkers to predict response to therapy in polyarticular juvenile idiopathic arthritis (JIA) is an important issue in pediatric rheumatology. A critical step in this process is determining whether there is biologic meaning to clinically derived terms such as "active disease" and "remission." The aim of this study was to use a systems biology approach to address this question. Methods We performed gene transcriptional profiling on children who fulfilled the criteria for specific disease states as defined by the consensus criteria developed by Wallace and colleagues. The study group comprised children with active disease (n = 14), children with clinical remission on medication (CRM; n = 9), children with clinical remission off medication (CR; n = 6), and healthy control children (n = 13). Transcriptional profiles in peripheral blood mononuclear cells (PBMCs) were obtained using Affymetrix U133 Plus 2.0 arrays. Results Hierarchical cluster analysis and predictive modeling demonstrated that the clinically derived criteria represent biologically distinct states. Minimal differences were seen between children with active disease and those with disease in CRM. Thus, underlying immune/inflammatory abnormalities persist despite a response to therapy. The PBMC transcriptional profiles of children whose disease was in remission did not return to normal but revealed networks of proinflammatory and antiinflammatory genes, suggesting that remission is a state of homeostasis, not a return to a normal state. Conclusion Gene transcriptional profiling of PBMCs revealed that clinically derived criteria for JIA disease states reflect underlying biology. We also demonstrated that neither CRM nor CR status results in resolution of the underlying inflammatory process, but that these conditions are more likely to be states of balanced homeostasis between proinflammatory and antiinflammatory mechanisms. [source] Human thiopurine methyltransferase activity varies with red blood cell ageBRITISH JOURNAL OF CLINICAL PHARMACOLOGY, Issue 5 2001L. Lennard Aims, Inherited differences in thiopurine methyltransferase (TPMT) activity are an important factor in the wide interindividual variations observed in the clinical response to thiopurine chemotherapy. The aim of this study was to establish a population range for red blood cell (RBC) TPMT activity in children with acute lymphoblastic leukaemia (ALL) at disease diagnosis. An additional aim was to investigate factors that can influence TPMT activity within the RBC. Methods,Blood samples were collected from children with ALL at disease diagnosis, prior to any blood transfusions, as part of the nationwide UK MRC ALL97 therapeutic trial. RBC TPMT activity was measured by h.p.l.c. RBCs were age-fractionated on Percoll density gradients. Results,Pretreatment blood samples were received from 570 children within 3 days of venepuncture. TPMT activities at disease diagnosis ranged from 1.6 to 23.6 units/ml RBCs (median 7.9) compared with 0.654,18.8 units (median 12.9), in 111 healthy control children (median difference 4.5 units, 95% CI 3.9, 5.1 units, P < 0.001). A TPMT quality control sample, aliquots of which were assayed in 60 analytical runs over a 12 month period, contained a median of 11.98 units with a CV of 11.6%. Seven children had their RBCs age-fractionated on density gradients. TPMT activities in the top gradient (young cells) ranged from 4.2 to 14.1 units (median 7.5) and in the bottom gradient (old cells) 1.5,12.6 units (median 4.7 units), median difference 2.3 units, 95% CI 0.7, 4.1, P = 0.035. Conclusions,Circulating RBCs do not constitute a homogeneous population. They have a life span of around 120 days and during that time undergo a progressive ageing process. The anaemia of ALL is due to deficient RBC production. The results of this study indicate that RBC TPMT activities are significantly lower in children with ALL at disease diagnosis. This may be due, at least in part, to a relative excess of older RBCs. [source] Reduced quality of life in children with Gastro-oesophageal reflux diseaseACTA PAEDIATRICA, Issue 3 2010M Marlais Abstract Aim:, To assess self-reported Quality of life (QoL) in children with Gastro-oesophageal reflux disease (GORD) aged 5,18 and compare this with both disease and healthy control children in a prospective consecutive sample. Methods:, All children attending a tertiary paediatric gastroenterology clinic from February 2009 to May 2009 with GORD, chronic constipation and inflammatory bowel disease (IBD) were asked to complete the validated PedsQL generic QoL assessment (self-report) at their clinic appointment. The PedsQL considers physical, emotional, social and school domains and is scored from 0 to 100. Healthy children were also recruited from the same site. Groups were compared using the independent samples Student's t -test. Results:, A total of 184 children completed the assessment [103 (56%) male, mean age 10.7 years ± 3.3] including 40 children with GORD, 44 with chronic constipation, 59 with IBD and 41 healthy children. QoL was significantly lower in the GORD group compared with both children with IBD (74 vs. 82) and healthy children (74 vs. 84), and was comparable to that of children with chronic constipation (74 vs. 74). Conclusions:, Self-reported QoL in children with GORD attending a tertiary paediatric gastroenterology clinic is significantly reduced compared with both healthy children and children with IBD. [source] Cognitive function at 10 years of age in children who have required neonatal intensive careACTA PAEDIATRICA, Issue 12 2004L Schermann Aim: To study cognitive function at 10 y of age in a cohort of children who required neonatal intensive care within the Uppsala Neonatal Follow-up Study. Methods: 226 children, who were born in 1986,1989 and had required neonatal intensive care (NIC) and 72 full-term, healthy control children were enrolled in the study. NIC children were grouped according to gestational age (group I, 23,31 wk; subgroup IA, 23,27 wk; IB 28,31 wk; group II, 32,36 wk; group III, >36wk), with infants with congenital malformation (IWCM) included and excluded from the main groups. The Kaufman Assessment Battery for Children (K-ABC) was administered and results were analysed in relation to the K-ABC global scales: sequential, simultaneous, mental processing composite and achievement. Results: The great majority of children had well-developed cognitive function, reaching scores at an average level or above. When groups were compared, full-term children that required NIC (group III) showed lower scores than controls on all scales measured by the K-ABC. Preterm children from all the studied groups (groups IA, IB, II) showed poorer performance than controls in the simultaneous processing scale, and group IA scored lower than controls in the achievement scale. The incidence of major cognitive impairment (IQ <70) was low in NIC children (<5%), but children from group IA showed significant higher frequency of impairment in the simultaneous, mental processing composite and achievement scales. Children from group IA presented a high frequency of discrepancy between the K-ABC scales, with lower simultaneous and higher sequential scores. Analysis with IWCM excluded from the main groups revealed identical results. Conclusion: Most children who needed neonatal intensive care had developed well their cognitive function at 10 y of age. The long-term effect of neonatal intensive care on cognitive function was more evident in extremely preterm infants (group IA), especially in tasks involving simultaneous ways of processing information.
