Abstract
The initial phases of COVID-19 emergency in Italy highlighted the technical delay that the national health system has accumulated in health services digitalization. Italian hospitals rapidly applied a demand systems for virtual health services based on tele-triage, tele-consultation and tele-visits procedures. This led, in the following months, the integration of virtual healthcare services applicable to the Azienda Ospedaliero Universitaria Pisa (AOUP). In particular, BCure system represents an important technological investment for the remote management of care protocols and the analysis of the complete use of health services. This is a unique system for sharing information between specialists, general practitioners and patients.

Abstract
Chyloperitoneum is not rare and is often associated with other chylous disorders particularly in more complex clinical conditions. An accurate diagnostic study is indispensable to plan the correct therapeutic approach, and we examined the long-term outcomes of our experience in the management of primary and secondary chyloperitoneum in fifty-eight patients (50 adults and 8 children; 34 primary and 24 secondary forms). Diagnostic assessment consisted of aracentesis, whole body lymphoscintigraphy, lymphangio-MR, and lymphangio-CT (LAG-CT). The management of chyloperitoneum consisted initially of non-operative procedures (MCT diet, TPN, octreotide). Surgical treatment was performed in patients not responsive to conservative methods and involved different options using surgical and microsurgical approaches. Microsurgical techniques included chylousvenous shunts connecting chyliferous vessels and mesenteric veins. Fibrin glue or platelet gel injection at the site of the chylous leakage was also used to treat one case of refractory secondary chyloperitoneum. Patients were followed clinically and instrumentally (echography and labs tests) for 6 months to over 5 years. We found that LAG-CT was the primary diagnostic modality to provide precise topographic information concerning the site, cause, and extension of chylous pathology, all of which allowed proper planning of therapeutic procedures. Thirty-four patients did not have a relapse of the chyloperitoneum and 22 patients had a persistence of a small quanitity of ascites with no protein imbalance. We observed early relapse of chylous ascites in 2 cases that required a peritoneal-jugular shunt leading to good outcomes. An accurate diagnostic study (above all LAG-CT) and a microsurgical approach proved to represent an effective management of chyloperitoneum refractory to non-operative treatment.

Abstract
OBJECTIVES Several strategies have been found to be effective for the treatment of childhood behavioral sleep disorders. One which has yet to be evaluated is the Zurich 3-step concept, which combines basic notions of the two-process model of sleep regulation (introducing a regular rhythm and adjusting bedtime to sleep need) with behavioral strategies. This uncontrolled before-and-after study describes our concept and its step-wise approach, assesses changes in sleep-wake variables and behavior problems, and also examines associations between changes in sleep-wake variables and behavior problems. METHODS A total of 79 children with sleep problems (age range 6-47 months, 42% females) were included. Sleep problems were assessed by the Infant Sleep Questionnaire, sleep-wake variables by diary and actigraphy, and behavior problems of children ≥ 18 months by the Child Behavior Checklist. RESULTS A significant decrease in nocturnal wake duration (Cohen's d = -0.34) and a significant increase in the duration of the longest continuous nocturnal sleep period (Cohen's d = 0.19) were found from before to after intervention (on average 2.7 months, SD 1.5). The variability for sleep onset and end time decreased, and actigraphically measured circadian rest-activity cycle measures improved. Parent-reported internalizing and total behavior problems also decreased (Cohen's d = 0.66). CONCLUSIONS The findings of both objective and subjective assessment techniques suggest that the Zurich 3-step concept is effective. Thus, the intervention concept may be useful in clinical practice with sleep-disordered children.

Abstract
ObjectiveTo assess nosocomial infection (NI) as a risk factor for death and to estimate the population-attributable risk of death from NI.Design.A prospective cohort study of patients with and without NI.Setting.Nîmes University Hospital, Nîmes, France.Patients.Patients were recruited from May 7, 2001, to January 10, 2003. Patients in acute care and long-term care units who had NI were enrolled, and patients without NI were randomly selected and matched with patients with NI for age, sex, type of care (acute care vs. long-term care) and length of stay in hospital at study inclusion.Outcome Measures.Vital status within 60 days after study inclusion was assessed. We used conditional logistic regression to estimate the relative death risk from NI after adjusting for comorbidities, severity of the underlying disease, and all other confounding factors. The adjusted population-attributable risk was assessed using the Mantel-Haenszel method.Results.We recruited 1,914 patients with NI and 5,172 patients without NI. The median age of the patients with NI was 73 years; 1,045 (54.6%) were female. NI was associated with death within 60 days (adjusted odds ratio, 1.7 [95% confidence interval {CI}, 1.4—;2.2]; P-C.001). The adjusted population-attributable risk of death for all sites of infection was 1.7% (95% CI, 1.4-2.1). If we consider the NI incidence to be 3%-6% in French hospitals, the population-attributable risk of death from NI would range from 2.1% (95% CI, 1.7%-2.5%) to 4.0% (95% CI, 3.3%-4.9%).Conclusion.In this study, NI appeared to have a significant impact on mortality. Multicenter studies will be needed to confirm these results.

Abstract
BACKGROUND Previous studies show contradictory results about the emergence of 24-h rhythms and the influence of external time cues on sleep-wake behavior in preterm compared to term infants. AIMS To examine whether very preterm infants (<32 weeks of gestational age) differ in their emergence of the 24-h sleep-wake rhythm at 5, 11 and 25 weeks corrected age compared to term infants and whether cycled light conditions during neonatal intermediate care affects postnatal 24-h sleep-wake rhythms in preterm infants. STUDY DESIGN Prospective cohort study with nested interventional trial. SUBJECTS 34 preterm and 14 control term infants were studied. During neonatal hospitalization, preterm infants were randomly assigned to cycled light [7 am-7 pm lights on, 7 pm-7 am lights off, n=17] or dim light condition [lights off whenever the child is asleep, n=17]. OUTCOME MEASURES Sleep and activity behavior recorded by parental diary and actigraphy at 5, 11 and 25 weeks corrected age. RESULTS Sleep at nighttime and the longest consolidated sleep period between 12 pm-6 am was longer (mixed model analysis, factor group: p=0.02, resp. p=0.01) and activity at nighttime was lower (p=0.005) at all ages in preterm compared to term infants. Cycled light exposed preterm infants showed the longest nighttime sleep duration. Dim light exposed preterm infants were the least active. CONCLUSIONS Preterm infants show an earlier emergence of the 24-h sleep-wake rhythm compared to term infants. Thus, the length of exposure to external time cues such as light may be important for the maturation of infant sleep-wake rhythms. Trial registry number: This trial has been registered at www.clinicaltrials.gov (identifier NCT01513226).

Abstract
We present a case of a 58 year-old woman with primary chylopericardium associated with chylothorax. Chylopericardium is a condition in which chylous fluid containing a high concentration of triglycerides accumulates in the pericardial cavity, and it can form for many different reasons. 3D computed tomography with lymphography precisely depicted the specific location of the lymphatic leak in this patient, which was successfully repaired using targeted video assisted thoracic surgery (VATS).

Abstract
BACKGROUND A reduced mouth opening capacity may be one of the first clinical signs of pathological changes in the masticatory system. The aim of this retrospective cross-sectional study was to create age related percentiles for unassisted maximal mouth opening capacity (MOC) of healthy children. METHODS All recordings of MOC as measured at the yearly dental examinations of school children in the city of Zurich, Switzerland, between August 2009 and August 2010 were extracted from the database. The program LMSchartMaker Pro Version 2.43, Huiqi Pan and Tim Cole, Medical Research Council, 1997-2010 was used to calculate age and sex related reference centiles. RESULTS Records from 22(')060 dental examinations were found during the study period. In 1286 (5.8%) the maximal interincisal measurement was missing. Another 55 examinations were excluded because of missing data for sex (7), age at examination (11) or because the value was deemed to be pathologically low (37). Thus, a total of 20(')719 measurements (10(')060 girls, 10(')659 boys) were included in the analysis. The median age (range) was 9.9 years (3.3-18.3) for girls and 10.0 years (2.8-18.7) for boys. The mean MOC (range) was 45 mm (25-69) for girls and 45 mm (25-70) for boys. Age related percentiles were created for girls and boys separately, showing the 3(rd), 10(th), 25(th), 50(th), 75(th), 90(th), and 97(th) percentile from 3 through 18 years of age. CONCLUSIONS In these 20(')719 unselected school children MOC increased with age but showed a wide range within children of the same age.

Abstract
Despite the development of minimal access dissection techniques, use of superficial groin dissection alone, and other recommendations to reduce morbidity in melanoma treatment, the incidence of lymphedema is still significant. The purpose of the current study was to assess the efficacy of microsurgical methods to limit the morbidity of inguinal lymphadenectomy. We conducted a retrospective review of patients who underwent groin dissection for melanoma treatment from February 2006 to April 2009. A total of 59 melanoma patients with positive groin lymph nodes comprised 18 patients (T-group) with melanoma in the trunk and 41 patients (E-group) who had melanoma in an extremity and currently have lymphedema. The T-group patients underwent primary prevention of lymphedema with microsurgical lymphatic-venous anastomoses (LVA) performed simultaneously with groin dissection. The E-group patients underwent LVA to treat the secondary lymphedema after an accurate oncological and lymphological assessment. Limb volume measurements and lymphoscintigraphy were performed pre- and postoperatively to assess short and long term outcome. No lymphedema occurred after microsurgical primary preventive approach in the T- group. Significant (average 80% reduction of pre-op excess volume) reduction of lymphedema resulted after microsurgical treatment for secondary leg lymphedema. Post-operative lymphoscintigraphy in 35 patients demonstrated patency of microsurgical anastomoses in all cases with an average follow-up of 42 months. Study results demonstrate that microsurgical LVA primary prevention prevented lymphedema after inguinal lymphadenectomy in the T-group patients. In addition, lymphatic-venous multiple anastomoses proved to be a successful treatment for clinical lymphedema with particular success if treated at the early stages.

Abstract
OBJECTIVES To assess health-related quality of life (HRQoL) and behavior of triplets compared with matched singletons at adolescent age and to identify medical and sociodemographic predictors of outcome. STUDY DESIGN Fifty-four triplets (19 sets, mean [SD] gestational age 32.0 [2.4] weeks, birth weight 1580 [450] g) and 51 gestational age-, birth weight-, and sex-matched singleton controls self-rated their HRQoL at age 14.5 (0.3) years. Proxy reports about HRQoL and behavior were obtained by parents and teachers. HRQoL was measured with the Kidscreen-52 questionnaire child and parent form, and behavior with the Achenbach Child Behavior Checklist. RESULTS Self- and parent-reported HRQoL values was similar in both groups except for the dimensions "mood and emotions" and "autonomy," which were better (P = .001, P = .03) in triplets. Parents reported significantly less behavioral problems in triplets compared with controls. Compared with community norms, both HRQoL and behavior measures in triplets were in the normal range. Parent-reported HRQoL was predicted by dichorionicity. CONCLUSIONS HRQoL and behavioral outcome in adolescent triplets was good in our study and was, in some aspects, better than in matched singleton controls. Dichorionicity is an important outcome determinant.

Abstract
OBJECTIVE To examine whether cycled lighting (CL) conditions during neonatal care in very preterm infants (<32 weeks' gestational age [GA]) decrease crying and fussing behavior, improve the consolidation of sleep, and influence activity behavior at 5 and 11 weeks' postterm corrected age (CA) compared with preterm infants cared for in dim lighting (DL) conditions. METHODS Thirty-seven preterm infants were randomly assigned to CL (7 am-7 pm lights on, 7 pm-7 am lights off [n = 17; mean GA: 30.6 ± 0.95 weeks; 9 girls]) or DL (lights off whenever the child is asleep [n = 20; GA: 29.5 ± 2.1 weeks; 8 girls]) conditions. Sleeping, crying, and activity behavior was recorded by using parental diaries and actigraphy at 5 and 11 weeks' CA. RESULTS A significant reduction of fussing (59.4 minutes/24 hours [± 25.8 minutes]) and crying (31.2 minutes/24 hours [± 14.4 minutes]) behavior and a trend to higher motor activity during daytime was found in CL-exposed infants at 5 and 11 weeks' CA compared with infants cared for in DL conditions. No significant difference between groups was observed for sleep behavior at 5 and 11 weeks' CA. Infants in CL conditions showed a trend to improved daily weight gain (average: 3.6 g/d) during neonatal care compared with DL conditions. CONCLUSIONS CL conditions in neonatal care have beneficial effects on infant's fussing and crying behavior and growth in the first weeks of life. This study supports the introduction of CL care in clinical neonatal practice.

Abstract
Congenital hypothyroidism (CH) can lead to intellectual deficits despite early high-dose treatment. Our study aimed to determine whether motor impairments can occur despite early high-dose treatment. Sixty-three children with CH and early (median age of onset of treatment 9 d), high-dose treatment (median starting dose of levothyroxine 14.7 μg/kg/d) were tested with the Zurich Neuromotor Assessment (ZNA) at a median age of 13.8 y (range 7.0-14.2 y). Median z-scores in the children with CH were -0.95 in the pure and -0.56 in the adaptive fine motor component, significantly lower than in the ZNA test norms (p < 0.001 and p = 0.01, respectively). The 26 children with athyreosis were more affected than the 33 children with dysgenesis, particularly in the pure motor (-1.55 versus -0.76, p = 0.03), adaptive fine motor (-1.31 versus 0.13, p < 0.01), and static balance task (-0.47 versus 0.67, p = 0.01). Boys performed worse than girls. Older age at onset of treatment was related to poorer adaptive fine motor performance. Movement quality (assessed by associated movements) was not affected. We conclude that severe CH can cause neuromotor deficits persisting into adolescence. These deficits cannot completely be reversed by postnatal treatment, but earlier age at treatment may reduce the degree of impairment.

Abstract
AIM We assessed motor and intellectual outcome in triplets at school age and investigated the predictive value of perinatal and demographic factors. METHODS Seventy-one live-born newborn infants (24 triplet pregnancies) were prospectively enrolled at birth. At the age of 6 years, 58 children (31 males, 27 females; mean gestational age 31.2 wks [SD 2.2 wks]; mean birthweight 1622 g [SD 440 g]) returned for a neurodevelopmental examination. A comparison group for triplets born before 32 gestational weeks comprising 26 gestational age-, birthweight-, and sex-matched singletons was also recruited (mean gestational age 30.1 wk [SD 1.5 wk]; mean birthweight 1142 g [SD 210 g]; 12 males, 14 females). The Zurich Neuromotor Assessment was used to examine motor performance, and intellectual abilities were assessed with the Kaufman Assessment Battery for Children (K-ABC). RESULTS Motor performance and movement quality in these individuals was significantly reduced compared with the test norms for all motor tasks (p<0.001) other than static balance. The mean values on the Mental Processing Composite (95.3, SD 8.4) and the Achievement Scale (90.1, SD 13.8) of the K-ABC were also lower than those in the test reference (p<0.05 and p<0.01 respectively). Triplets born at less than 32 weeks' gestation showed poorer pure motor and adaptive gross motor performance (both p<0.05) than, but similar intellectual performance to, the gestational age-, birthweight- and sex-matched singletons. Poor outcome was predicted by low socio-economic status and by intertriplet birthweight discordance (both p<0.01). INTERPRETATION Triplets were at an increased risk of mild motor and intellectual impairments. This finding is important for tailoring therapeutic interventions for these children and for parental counselling. Very preterm triplets showed similar outcomes to the singleton comparison children, except that they had poorer motor performance. Low socio-economic status was a major risk factor for impaired intellectual development. In addition, birthweight discordance may also be considered a predictor for poor long-term motor and intellectual outcome in triplets.

Abstract
OBJECTIVES Central obesity, measured as waist circumference (WC), is an important risk factor for cardiovascular disease and diabetes already in children. The ratio of waist circumference to height (WHtR) is a further indicator for body shape. International reference values, however, do not exist for any of the two measures and neither do references specific to Switzerland. The aim of this study therefore was to develop WC and WHtR percentiles from a nationally representative sample of Swiss children. METHODS In a nationally representative sample of 2,303 6 to 13 year old children in Switzerland weight, height and WC were measured and body fat % (%BF) was determined from multiple skinfold-thickness measurements. WC, WHtR and % BF percentiles were calculated using the LMS-Method of Cole and Green. RESULTS WC increases almost linearly over the age range of 6 to 13 years for both boys and girls. Generally, girls show slightly lower WC than boys, but in the higher percentiles (85th, 90th and 95th) they reach the same or even slightly higher values around 10 years of age. At the 85th percentile for boys and the 90th percentile for girls, WHtR remains constant over the entire age range. Above these levels the ratio increases and below it decreases with age. Percentiles for %BF in boys increase constantly up to an age of 11.5 years, after which they plateau. For girls, the plateau can be seen earlier, around 10.5 years, but at 12.5 years another increase begins. CONCLUSION These first WC and WHtR percentiles may be useful for clinical and epidemiological use in Switzerland until official, validated references become available. An advantage in using WHtR seems to be that it is not age dependent at certain levels and it may therefore be possible to use a single cut-off value for all children.

Abstract
BACKGROUND The prevalence of childhood obesity is increasing rapidly in most industrialised countries, but several countries, including Switzerland, have recently reported a levelling off or even a reversal of this alarming trend. STUDY AIM Our aim was to evaluate the prevalence of childhood obesity in a national sample of Swiss school children recruited to assess iodine nutrition and with this to reconfirm a recently shown stabilising trend. DESIGN Using a probability-proportionate-to-size cluster sampling, 6 to 12 year old children (n = 907) were recruited in a study of iodine status in Switzerland. Height and weight were measured and body mass index calculated in all children. RESULTS The prevalence of overweight detected was 12.5% (SE = 1.6) in boys and 12.8% (1.6) in girls while 6.2% (1.1) of boys and 4.2% (0.9) of girls were classified as obese. The highest prevalence of overweight and obesity were found in the Southern region and in bigger cities (>100000 inhabitants). Compared to the most recent national study in 2007, the prevalence was slightly higher, but the differences were not significant, suggesting negative sampling bias does not strongly affect surveys of paediatric adiposity in Switzerland. CONCLUSION This present study clearly confirms the stabilisation of the prevalence of childhood overweight and obesity in Switzerland.

Abstract
BACKGROUND Longitudinal data on bone age progression is scarce. AIM The study aimed to present reference values for Tanner-Whitehouse 3 (TW3) bone age score and score increments, and to provide means and standard deviations of appearance time for all TW3 stages. Gender differences and differences between radio ulna and short bones (RUS) and carpal bone (CB) scores were studied. SUBJECTS AND METHODS Bone age data collected for ages 3 months to 20 years in 232 subjects during the First Zurich Longitudinal Study (1954-1976) were used. Smoothed empirical percentiles of TW3 RUS and CB scores for age, of score increments for age and of score increments for attained score are presented. Means and standard deviations of the appearance times are calculated by parametric censored regression. RESULTS There are clear differences between the RUS and CB scores and between the genders. Boys are delayed with respect to girls, with different delays for RUS and CB. For RUS, differences in maturation reflect the known differences of physical growth, with a later and more intense peak in boys. For CB, there is little difference in timing and intensity. However, girls reach the final score about 2 years earlier than boys. The consistently earlier mean appearance times in girls indicate that skeletal maturation is, already in childhood, more rapid in girls than in boys. There are significant gender differences in the sequence of appearance. CONCLUSION Reference values for TW3 score and score increments and mean appearance times for stages add to existing knowledge and indicate important RUS/CB and gender differences, whose sources are largely unknown.

Abstract
BACKGROUND Information on the effect of variability in maturational tempo on variability in height attained at the same age is not readily available. AIM The study obtained this information from the data of the First Zurich Longitudinal Study. SUBJECTS AND METHODS Yearly measurements of standing height, sitting height and leg length, yearly assessments of bone age (RUS (Radius, Ulna and Short bones), TW3 method) and midparent height for 232 children from the First Zurich Longitudinal Growth Study are included in a correlational analysis. RESULTS The course of the squared correlations of standing height, sitting height and leg length with attained RUS bone age, midparent height and both as a function of age are presented. CONCLUSIONS During puberty, up to 50% of the height variation in boys and 40% in girls is explained by maturational tempo.

Abstract
PURPOSE Parents frequently report increased sleep duration in their children during treatment with valproic acid (VPA). We assessed sleep duration and sleep behavior before and after tapering VPA in children treated for more than 6 months. METHODS Sleep variables were assessed by questionnaire, diary, and actigraphy (for 7 consecutive days and nights) before and 8-12 weeks after termination of VPA. RESULTS Forty-six children (age range 1.7-17.4 years) completed the study. The questionnaire data showed no significant difference in bed and wake time, duration of sleep, and time to fall asleep before and after ending VPA treatment, although some qualitative measures on daytime sleepiness improved after tapering VPA. The actigraphy data revealed that the average sleep amount without VPA was reduced in 33 children (9 of them >30 min) and longer in 13 children (1 of them >30 min). The mean Assumed Sleep Time per Day decreased by 15.2 min or 9.5 min when the physiologic decrease of sleep duration within 0.3 years was considered. Also mean Actual Sleep Time per Day was significantly reduced after VPA termination (-15.2 min; after correction -10.7 min). The reduction was only significant in children older than age 6 years. DISCUSSION Termination of VPA after long-term treatment leads to a significant reduction of sleep duration in children older than 6 years of age. The change was small in the majority, but considerable in a subgroup of children.

Abstract
We aim to determine long-term intellectual outcome of adolescents with early high-dose treated congenital hypothyroidism (CH). Sixty-three prospectively followed children with CH were assessed at age of 14 y with the Wechsler Intelligence Scale for Children-Revised and compared with 175 healthy controls. Median age at onset of treatment was 9 d (range 5-18 d) and median starting dose of levothyroxine (L-T4) was 14.7 microg/kg/d (range 9.9-23.6 microg/kg/d). Full-scale intelligence quotient (IQ) was significantly lower than in controls after adjustment for socioeconomic status (SES) and gender (101.7 versus 111.4; p < 0.0001). Children with athyreosis had a lower performance IQ than those with dysgenesis (adjusted difference 7.6 IQ scores, p < 0.05). Lower initial thyroxine (T4) levels correlated with poorer IQ (r = 0.27, p = 0.04). Lower SES was associated with poorer IQ, in particular in children with CH (interaction, p = 0.03). Treatment during childhood was not related to IQ at age 14 y. Adolescents with CH manifest IQ deficits when compared with their peers despite early high-dose treatment and optimal substitution therapy throughout childhood. Those adolescents with athyreosis and lower SES are at particular risk for adverse outcome. Therefore, early detection of intellectual deficits is mandatory in children with CH.

Abstract
Background/Objectives: Insulin resistance (IR) and hypertension are common in overweight children, and the adipocyte-derived hormones resistin, adiponectin, and leptin may modulate IR and blood pressure (BP). Few data exist in children on dietary determinants of IR, BP, or leptin, and no data exist on dietary determinants of resistin and adiponectin. Therefore, the objective of this study was to investigate dietary determinants of IR, BP, resistin, adiponectin, and leptin concentrations, as well as the interrelationship among these variables, in normal and overweight children. Subjects/Methods: In 6- to 14-year-old Swiss children (n=79), nutritional intake was assessed using two 24-hour-recalls and a one-day dietary record. Body mass index (BMI), body fat percentage (BF%), waist/hip ratio (W/H ratio), BP, glucose, insulin, resistin, adiponectin, and leptin were determined. IR was calculated using the quantitative insulin sensitivity check index (QUICKI). Results: BMI, BF%, and W/H ratio were significant predictors of leptin and insulin, QUICKI, and systolic BP, but not resistin or adiponectin. Of the overweight and obese children, 40 % were diagnosed pre-hypertensive or hypertensive. Total energy, fat, saturated fat, and protein intakes were significant predictors of fasting insulin and QUICKI, and total fat, saturated fat, and monounsaturated fat intakes were significant predictors of systolic BP, independent of BMI standard deviation score (BMI-SDS) and age. There were no associations between these dietary factors and leptin, adiponectin, or resistin. Conclusion: In children, dietary macronutrient composition is a predictor of IR and systolic BP, but not resistin, adiponectin, or leptin concentrations. Resistin and adiponectin concentrations are not correlated with IR or BP in this age range.

Abstract
The hypothesis was tested that oral antibiotic treatment in children with acute pyelonephritis and scintigraphy-documented lesions is equally as efficacious as sequential intravenous/oral therapy with respect to the incidence of renal scarring. A randomised multi-centre trial was conducted in 365 children aged 6 months to 16 years with bacterial growth in cultures from urine collected by catheter. The children were assigned to receive either oral ceftibuten (9 mg/kg once daily) for 14 days or intravenous ceftriaxone (50 mg/kg once daily) for 3 days followed by oral ceftibuten for 11 days. Only patients with lesions detected on acute-phase dimercaptosuccinic acid (DMSA) scintigraphy underwent follow-up scintigraphy. Efficacy was evaluated by the rate of renal scarring after 6 months on follow-up scintigraphy. Of 219 children with lesions on acute-phase scintigraphy, 152 completed the study; 80 (72 females, median age 2.2 years) were given ceftibuten and 72 (62 females, median age 1.6 years) were given ceftriaxone/ceftibuten. Patients in the intravenous/oral group had significantly higher C-reactive protein (CRP) concentrations at baseline and larger lesion(s) on acute-phase scintigraphy. Follow-up scintigraphy showed renal scarring in 21/80 children treated with ceftibuten and 33/72 with ceftriaxone/ceftibuten (p = 0.01). However, after adjustment for the confounding variables (CRP and size of acute-phase lesion), no significant difference was observed for renal scarring between the two groups (p = 0.2). Renal scarring correlated with the extent of the acute-phase lesion (r = 0.60, p < 0.0001) and the grade of vesico-ureteric reflux (r = 0.31, p = 0.03), and was more frequent in refluxing renal units (p = 0.04). The majority of patients, i.e. 44 in the oral group and 47 in the intravenous/oral group, were managed as out-patients. Side effects were not observed. From this study, we can conclude that once-daily oral ceftibuten for 14 days yielded comparable results to sequential ceftriaxone/ceftibuten treatment in children aged 6 months to 16 years with DMSA-documented acute pyelonephritis and it allowed out-patient management in the majority of these children.

Abstract
OBJECTIVES To describe sleep-wake patterns in kindergarten children by measures derived from questionnaire, diary, and actigraphy and to report rates of agreement between methods according to Bland and Altman. DESIGN Cross-sectional study, data from 7 nights of actigraph recordings and sleep diary and from a questionnaire. SETTING Children studied in their homes. PARTICIPANTS Fifty children, aged 4 to 7 years. MAIN OUTCOME MEASURES Sleep start, sleep end, assumed sleep, actual sleep time, and nocturnal wake time derived from different methods. RESULTS Differences between actigraphy and diary were +/- 28 minutes for sleep start, +/- 24 minutes for sleep end, and +/- 32 minutes for assumed sleep, indicating satisfactory agreement between methods, whereas for actual sleep time and nocturnal wake time, agreement rates were not sufficient (+/- 106 minutes and +/- 55 minutes, respectively). Agreement rates between actigraphy and questionnaire as well as between diary and questionnaire were insufficient for all variables. Sex and age of children and socioeconomic status did not influence the differences between methods for all variables. CONCLUSIONS Actigraphy and diary may be interchangeably used for the assessment of sleep start, sleep end, and assumed sleep but not for nocturnal wake times. The diary is a cost-effective and valid source of information about children's sleep-schedule times, while actigraphy may provide additional information about nocturnal wake times or may be used if parents are unable to report in detail. It is insufficient to collect information by a questionnaire or an interview asking about children's normal sleep patterns.

Abstract
A retrospective chart review was performed of all patients with juvenile idiopathic arthritis (JIA) followed at our clinic who had an intra-articular steroid injection between 1 January 1997 and 31 December 2001. The aim of the study was to evaluate the outcome of intra-articular steroid injections (iaS) and determine prognostic factors. During the study period, 202 iaS were performed in 60 patients, of whom 37 had oligoarticular JIA, 15 had polyarticular, rheumatoid factor-negative JIA and four each had systemic and enthesitis-related JIA. The median duration of remission was 23.1 months (range: 0-69 months). At last follow-up, 103 joints (51%) of 47 patients were still in remission after a median follow-up time of 28 months (range: 1-69 months). For the total cohort, the remission was longer for wrist and finger joints [risk ratio (RR): 0.2], with concomitant treatment with methotrexate (RR: 0.28) and for enthesitis-related arthritis (RR: 0.34). For the group of knee joints, remission was longer with concomitant treatment with methotrexate (RR: 0.37), with triamcinolone hexacetonide (RR: 0.77) and with general anaesthesia for the procedure (RR: 0.56). Mild side effects were observed in 45 iaS (22.3%), and skin atrophy occurred at the injection site in 2% of injections, but no major adverse event occurred in our cohort. In conclusion, iaS is a safe procedure with a median duration of remission of 23.1 months. The remission was longer in the joints of the upper extremity, with concomitant treatment with methotrexate and when the injection was performed under general anaesthesia.

Abstract
OBJECTIVE Our goal was to describe the variability of sleep duration (time in bed per 24 hours) in healthy children from 1 to 10 years of age in comparison with growth measures. METHODS A total of 305 children were followed with structured sleep-related interviews and measurements of height and weight 12, 18, and 24 months after birth and then at annual intervals until 10 years of age. SD scores were calculated, and smooth curves were fitted by smoothing splines through the SD scores. The long-term variability channel within children (units SD score) was defined as the difference between the maximum and the minimum of the smooth curves and the short-term variability channel (units SD score) as the difference of the largest and the smallest deviations of the original SD scores from the smooth curve. RESULTS Sleep duration remained within a long-term variability channel <0.5 SD score in 21% of the children (34% for height, 21% for weight). Nearly every second child (46%) stayed within a long-term variability channel <1.0 SD score (76% for height, 64% for weight). Sleep duration of approximately 90% of all children ran within a long-term variability channel of <2.0 SD score (corresponding, eg, to the range between the 2nd and the 50th percentile). No single child's sleep duration remained within a short-term variability channel <0.5 SD score, indicating fluctuations from year to year (60% for height, 53% for weight). An association between aspects of sleep duration and somatic growth was not observed at any age. CONCLUSIONS Sleep duration during early and middle childhood shows large variability among children, as well as trait-like long-term stability and state-like yearly fluctuations within children. An individual approach to the child's sleep behavior is needed; expectations in terms of appropriate sleep duration of the child should be adjusted to the individual sleep need.

Abstract
BACKGROUND High amounts of dietary fructose may contribute to dyslipidemia in adults, but there are few data in children. Childhood adiposity is associated with smaller LDL particle size, but the dietary predictors of LDL size in overweight children have not been studied. OBJECTIVES We aimed to determine whether LDL particle size is associated with dietary factors and specifically with fructose intake in normal-weight and overweight children. DESIGN In a cross-sectional study of normal-weight and overweight 6-14 y-old Swiss children (n = 74), dietary intakes were assessed by using two 24-h-recalls and a 1-d dietary record. Body mass index (BMI) and waist-hip ratio (WHR) were measured, and plasma lipid profile and LDL particle size were determined. RESULTS Compared with the normal-weight group, overweight children had significantly higher plasma triacylglycerol concentrations, lower HDL-cholesterol concentrations, and smaller LDL particle size (P < 0.05). LDL particle size was inversely correlated to BMI SD scores and WHR (P = 0.007). Although there were no significant differences in total fructose intake, the overweight children consumed a significantly (P < 0.05) higher percentage of fructose from sweets and sweetened drinks than did the normal-weight children. After control for adiposity, the only dietary factor that was a significant predictor of LDL particle size was total fructose intake (P = 0.024). CONCLUSIONS In school-age children, greater total and central adiposity are associated with smaller LDL particle size and lower HDL cholesterol. Overweight children consume more fructose from sweets and sweetened drinks than do normal-weight children, and higher fructose intake predicts smaller LDL particle size.

Abstract
The dramatic world-wide trend towards increasing body weight seems to be less obvious in the Japanese population. The aim of this study is to extract potentially useful information regarding childhood and adolescence obesity in Japan from series of mean height and mean body mass index between 1948 and 2003. Mean values for height and weight of Japanese boys and girls aged 5+ to 17+ years were obtained from the "Reports on School Health Survey", Ministry of Education, Culture, Sports, Science and Technology, comprising approximately 4.5% of all children and adolescents in Japan between 1948 and 2003. The data were fitted by the Preece and Baines model (Preece & Baines 1978) in order to obtain estimates of the age of peak height velocity (APHV) and final height. Isochrones for height and BMI were calculated based upon measurements that were obtained at the same chronological ages at different historic epochs. The APHV as estimated by Preece & Baines (1978) has decreased from 14.07 to 12.03 years in Japanese boys, and from 11.80 to 9.92 years in Japanese girls, indicating that the tempo of child and adolescent maturation (maturational tempo) has accelerated. Body height increased by 10.1 cm in near adult 17+ year old Japanese males and by 5.7 cm in 17+ year old Japanese females since 1948. Due to the acceleration and the earlier attainment of adult stature, isochrones for height tend to diverge for prepubertal ages and to converge for postpubertal ages. The same is true for weight. Body weight has increased by 11.8 kg in near adult males, and by 4.4 kg in near adult females. Also BMI has increased since 1948. But in contrast to height and weight, the rise in BMI only reflects the acceleration of the maturational tempo. Tempo-conditioned isochrones for BMI are almost horizontal, and even tended to temporarily decrease during the 60ies and the 70's. The BMI of Japanese children and adolescents dramatically contrasts the recent and historic BMI changes in the Western populations. The present study provides no evidence of any major rise in the prevalence of obesity in Japan as expressed by mean BMI for age and time of birth, and suggests that Japanese children and adolescents may be more resistant against those environmental factors that have caused obesity in the affluent Western societies.

Abstract
The Waldeyer's ring designates a functional unit of lymphoid tissue within the pharynx including the adenoids and tonsils. To gain insight into distribution patterns of beta- and gamma-human herpesviruses (HHVs) and their potential mutual influences at their natural portal of entry, quantitative polymerase chain reaction (qPCR) assays were applied to adenoids and tonsils obtained from 30 children. DNA of Epstein-Barr virus (EBV), cytomegalovirus (CMV), HHV-6, HHV-7, and HHV-8 was detected in adenoids, tonsils, or both of 24 (80%), 19 (63%), 23 (77%), 23 (77%), and 0 (0%) children, respectively. EBV, CMV, HHV-6, and -7 localized in both adenoids and tonsils from 92%, 37%, 52%, and 70% of children, respectively, with the virus detectable by qPCR. The amount of EBV was 2-10-fold higher than of other HHVs and correlated in autologous organs (P = 0.01) as did the amount of HHV-7 (P = 0.002). The amount of CMV correlated with the HHV-6 amount in adenoids (P = 0.028) and tonsils (P = 0.007), and with the amount of HHV-7 in adenoids (P < 0.01). Levels of HHV-6 DNA were lower in adenoids with detectable CMV DNA than in adenoids without detectable CMV DNA (P = 0.0062). Inversely, CMV and HHV-7 levels were higher in adenoids with than in adenoids without detectable EBV DNA (P = 0.019 and P = 0.039, respectively).Thus, beta- and gamma-HHV exhibit distinct distribution behaviors in Waldeyer's ring organs and seem to interact. This may be of medical importance in immunocompromised hosts who are likely to reactivate HHVs causing severe morbidity and death.

Abstract
The occurrence of generalised tonic-clonic seizures (GTCS) was investigated in patients with absence epilepsy (AE), evaluating the opinion that ethosuximide does not protect against GTCS. Our retrospective study included 238 patients with absences and generalised 3-Hz spike waves (SW). We analysed the efficacy of antiepileptic drugs (AED) and the occurrence of GTCS before, during and after treatment. We surveyed family history, treatment delay and EEG findings. Family history of epilepsy was positive in 28%. Children with 3-Hz SW lasting >10 s suffered less frequently from GTCS (p=0.002). Photosensitivity (3-Hz SW during photic stimulation) recorded in 47 children was more frequent in juvenile AE (p=0.0001), but not associated with higher rates of GTCS. GTCS occurred in 27 children (11%) before treatment, in 14 (5.8%) during treatment and in 8 (4.8%) after tapering AED. Valproate and ethosuximide monotherapy were equally effective on absences, carrying the same low risk of GTCS during treatment (2 valproate, 1 ethosuximide). Most GTCS occurred on drug combinations considered effective against GTCS. Risk factors for relapses after tapering AED were photosensitivity (p=0.002) and GTCS during treatment (p=0.02). GTCS are rare in patients with typical AE. Our data do not support the current opinion that ethosuximide is inefficacious on GTCS in AE.

Abstract
CONTEXT Thyroglobulin (Tg) may be a valuable indicator of improving thyroid function in children after salt iodization. A recently developed Tg assay for use on dried whole blood spots (DBS) makes sampling practical, even in remote areas. OBJECTIVE The study aim was to develop a reference standard for DBS-Tg, establish an international reference range for DBS-Tg in iodine-sufficient children, and test the standardized DBS-Tg assay in an intervention trial. DESIGN, PARTICIPANTS, AND INTERVENTIONS Serum Tg reference material of the European Community Bureau of Reference (CRM-457) was adapted for DBS and its stability tested over 1 yr. DBS-Tg was determined in an international sample of 5- to 14-yr-old children (n = 700) who were euthyroid, anti-Tg antibody negative, and residing in areas of long-term iodine sufficiency. In a 10-month trial in iodine-deficient children, DBS-Tg and other indicators of iodine status were measured before and after introduction of iodized salt. RESULTS Stability of the CRM-457 Tg reference standard on DBS over 1 yr of storage at -20 and -50 C was acceptable. In the international sample of children, the third and 97th percentiles of DBS-Tg were 4 and 40 microg/liter, respectively. In the intervention, before introduction of iodized salt, median DBS-Tg was 49 microg/liter, and more than two thirds of children had DBS-Tg values greater than 40 microg/liter. After 5 and 10 months of iodized salt use, median DBS-Tg decreased to 13 and 8 microg/liter, respectively, and only 7 and 3% of children, respectively, had values greater than 40 microg/liter. DBS-Tg correlated well at baseline and 5 months with urinary iodine and thyroid volume. CONCLUSIONS The availability of reference material and an international reference range facilitates the use of DBS-Tg for monitoring of iodine nutrition in school-age children.

Abstract
AIM To study clinically relevant aspects of sleep behaviour in preterm children in comparison to term children. METHODS Longitudinal sleep behaviour data were collected prospectively by structured interviews in 130 preterm and 75 control term children from birth to age 10 y. RESULTS No significant differences in sleep duration (time in bed per 24 h), bedsharing, night wakings, bedtime resistance and sleep-onset difficulties were found between preterm and term children. CONCLUSION Sleep behaviour does not differ between preterm and term children from birth to age 10 y, indicating that prematurity or neonatal intensive care experience does not significantly affect sleep in the first 10 y of life.

Abstract
BACKGROUND In obese children, subclinical inflammation is often present and is correlated with the metabolic syndrome. Dietary factors, such as fatty acids and antioxidants, potentially modulate the association between adiposity and subclinical inflammation, but few data are available in children. OBJECTIVE The aim of the study was to determine whether dietary fat or antioxidant intakes influence circulating tumor necrosis factor alpha (TNF-alpha), interleukin 6 (IL-6), C-reactive protein (CRP), and leptin concentrations in overweight children. DESIGN In a cross-sectional study of 6-14-y-old normal-weight (n = 33), overweight (n = 19), and obese (n = 27) Swiss children, nutritional intakes were assessed from two 24-h dietary recalls and a 1-d dietary record. Percentage body fat from skinfold thicknesses, waist-hip ratio, and blood pressure were measured. Fasting blood samples were collected for the measurement of insulin, glucose, HDL-cholesterol, triacylglycerol, CRP, IL-6, TNF-alpha, and leptin concentrations. RESULTS CRP, IL-6, and leptin increased significantly (P < 0.02) with increasing adiposity, independent of age; TNF-alpha did not increase. Total dietary fat and the percentage of energy from fat were significant predictors of CRP concentration, independent of body mass index (P < 0.05). Meat intake was a significant predictor of IL-6 and leptin, independent of body mass index (P < 0.05). Intakes of antioxidant vitamins (vitamins E and C and beta-carotene) were significant predictors of leptin (P < 0.05) but not of CRP, IL-6, or TNF-alpha. CONCLUSIONS Overweight Swiss children as young as 6 y have elevated concentrations of inflammatory markers. Intakes of total fat and antioxidant vitamins are determinants of subclinical inflammation in this age group.

Abstract
UNLABELLED The clinical diagnosis of Marfan syndrome in childhood is difficult, because symptoms may not have developed to their full expression until adulthood. The Ghent nosology for the diagnosis of Marfan syndrome classifies dural ectasia as a major diagnostic criterion. More than two thirds of adult patients with Marfan syndrome show dural ectasia, while the frequency in childhood is unknown. This prospective multicenter observational patient-control study was performed to identify pathologic changes of the lumbosacral spine in young patients with Marfan syndrome. DESIGN Prospective clinical trial, multicentric, cross-sectional. SETTING MRI of the lumbosacral spine. PATIENTS Twenty patients with proven Marfan syndrome, 20 patients suspicious for Marfan syndrome and 38 healthy controls. OUTCOME MEASURES Vertebral body diameter (VBD) from L1 to S1, dural sac diameter (DSD) from L1 to S1, dural sac ratio (DSR), qualitative assessment of the lumbosacral spine. RESULTS DSD and VBD in different age groups were higher in patients with proven or suspected Marfan syndrome than in healthy controls (DSD: L1, 6-8 years, P < 0.05). VBD related to body height showed a similar growth related increase in patients with proven or suspected Marfan syndrome and controls. DSD related to body height was elevated in patients with proven or suspected Marfan syndrome at different levels of the lumbar spine. DSD at levels L1, L5, and S1, and DSR at levels L5 and S1 of patients with proven Marfan syndrome were significantly higher (P < 0.05) than in controls. CONCLUSION Even during childhood pathologic changes inside the lumbosacral spine of patients with Marfan syndrome can be observed. Dural ectasia, which occurs at different levels of the lumbar spine, can be detected at levels L5 and S1 in up to 40% of patients with Marfan syndrome.

Abstract
The World Health Organization (WHO), in collaboration with a number of research institutions worldwide, is developing new child growth standards. As part of a broad consultative process for selecting the best statistical methods, WHO convened a group of statisticians and child growth experts to review available methods, develop a strategy for assessing their strengths and weaknesses, and discuss methodological issues likely to be faced in the process of constructing the new growth curves. To select the method(s) to be used, the group proposed a two-stage decision-making process. First, to select a few relevant methods based on a list of set criteria and, second, to compare the methods using available tests or other established procedures. The group reviewed 30 methods for attained growth curves. Using the pre-defined criteria, a few were selected combining five distributions and two smoothing techniques. Because the number of selected methods was considered too large to be fully tested, a preliminary study was recommended to evaluate goodness of fit of the five distributions. Methods based on distributions with poor performance will be eliminated and the remaining methods fully tested and compared.

Abstract
Very low birth weight born children manifest a higher prevalence of motor and cognitive impairments than term children. Seventy-four prospectively enrolled children born < 1250 g underwent testing of motor (Zurich neuromotor assessment ZNA: timed motor performances and associated movements) and cognitive functions (Kaufman-ABC) at age six years. Children with cerebral palsy or mental retardation were excluded. Adaptive motor tasks (pegboard and dynamic balance) and visuomotor cognitive functions were specifically impaired, and a distinct correlation pattern between motor and cognitive abilities was detected. The adaptive fine motor task (pegboard) correlated with visuomotor functions of the Kaufman-ABC ("triangles", r = 0.35; "matrix analogies", r = 0.39), while pure motor tasks of the ZNA (repetitive, alternating, and sequential movements) did not in spite of impaired motor performance. Timed motor performance below the 10th percentile correlated strongly with cognitive delay (IQ < 85: adaptive fine motor: OR 6.0 [95% CI] 4.7-7.3; adaptive gross motor: OR 7.0 [CI 5.6-8.4]; static balance: OR 9.6 [CI 8.2-11.0]). In conclusion, motor deficits in children born < 1250 g without severe disabilities correlate with specific cognitive impairments, in particular of the visuomotor domain. The correlation pattern may indicate specific dysfunction in visuomotor transformation, the intermediate process between visual-perceptual input and motor output. Early assessment of both motor and cognitive functions using standardized assessment tools is important to determine the extent and combination of specific developmental disturbances and to tailor therapeutic intervention.

Abstract
Pediatric cardiac surgery with cardiopulmonary bypass (CPB) is frequently associated with neurologic deficits. We describe the postoperative EEG changes, assess their possible causes, and evaluate their relevance to neurologic outcome. Thirty-one children and five neonates with congenital heart disease were included. EEG recording started after intubation and continued until 22-96 h after CPB. In addition to conventional analysis, spectral analysis was performed for occipital and frontal electrodes, and differences between pre- and postoperative delta power (delta-deltaP) were calculated. Maximum values of occipital delta-deltaP that occurred within 48 h after CPB were correlated with clinical variables and with perioperative markers of oxidative stress and inflammation. Occipital delta-deltaP correlated with frontal delta-deltaP, and maximum delta-deltaP correlated with conventional rating. Distinct rise of deltaP was detected in 18 of 21 children without any acute or long-term neurologic deficits but only in five of 10 children with temporary or permanent neurologic deficits. Furthermore, maximally registered delta-deltaP was inversely associated with duration of CPB and postoperative ventilation. Maximal delta-deltaP was also inversely associated with the loss of plasma ascorbate (as an index of oxidative stress) and plasma levels of IL-6 and IL-8. Slow wave activity frequently occurs within 48 h after CPB. However, our data do not support the notion that EEG slowing is associated with adverse neurologic outcome. This is supported by the fact that EEG slowing was associated with less oxido-inflammatory stress.

Abstract
BACKGROUND There are few data on the adverse effects of chronic exposure to high iodine intakes, particularly in children. OBJECTIVE The objective of the study was to ascertain whether high dietary intakes of iodine in children result in high thyroid volume (Tvol), a high risk of goiter, or both. DESIGN In an international sample of 6-12-y-old children (n = 3319) from 5 continents with iodine intakes ranging from adequate to excessive, Tvol was measured by ultrasound, and the urinary iodine (UI) concentration was measured. Regressions were done on Tvol and goiter including age, body surface area, sex, and UI concentration as covariates. RESULTS The median UI concentration ranged from 115 microg/L in central Switzerland to 728 microg/L in coastal Hokkaido, Japan. In the entire sample, 31% of children had UI concentrations >300 microg/L, and 11% had UI concentrations >500 microg/L; in coastal Hokkaido, 59% had UI concentrations >500 microg/L, and 39% had UI concentrations >1000 microg/L. In coastal Hokkaido, the mean age- and body surface area-adjusted Tvol was approximately 2-fold the mean Tvol from the other sites combined (P < 0.0001), and there was a positive correlation between log(UI concentration) and log(Tvol) (r = 0.24, P < 0.0001). In the combined sample, after adjustment for age, sex, and body surface area, log(Tvol) began to rise at a log(UI concentration) >2.7, which, when transformed back to the linear scale, corresponded to a UI concentration of approximately 500 microg/L. CONCLUSIONS Chronic iodine intakes approximately twice those recommended-indicated by UI concentrations in the range of 300-500 microg/L-do not increase Tvol in children. However, UI concentrations >/=500 microg/L are associated with increasing Tvol, which reflects the adverse effects of chronic iodine excess.

Abstract
BACKGROUND Although transferrin receptor (TfR) and zinc protoporphyrin (ZnPP) are often used to define iron status in school-age children in developing countries, the diagnostic cutoffs for this age group are uncertain. OBJECTIVE The objective was to determine the sensitivity and specificity of TfR and ZnPP in predicting iron deficiency in black and white children in Africa. DESIGN Hemoglobin, C-reactive protein (CRP), serum ferritin (SF), TfR, and ZnPP were measured in children in Côte d'Ivoire and Morocco. We excluded children with elevated CRP and then used receiver operating characteristic (ROC) curves to evaluate TfR and ZnPP alone and in combination in screening for iron deficiency, defined as an SF concentration <15 mug/L, and iron deficiency anemia (IDA), defined as an SF concentration <15 mug/L and low hemoglobin. RESULTS The sample included 2814 children aged 5-15 y. The sensitivity and specificity of TfR and ZnPP were limited by considerable overlap between iron-sufficient, nonanemic children and those with IDA. On the basis of ROC curves, we identified diagnostic cutoffs for TfR and ZnPP that achieved specificities and sensitivities of approximately 60-80%. Separate cutoffs for Côte d'Ivoire and Morocco gave the best performance; the cutoffs for both TfR and ZnPP were higher in Côte d'Ivoire. Moreover, a comparison of nonanemic, iron-sufficient subjects showed that Ivorian children had significantly higher TfR and ZnPP concentrations than did Moroccan children (P < 0.01). CONCLUSIONS New diagnostic cutoffs for TfR and ZnPP, based on ROC curve analyses, may improve the performance of these indexes in defining iron status in children. Significant ethnic differences in TfR and ZnPP suggest that separate cutoffs may be needed for black and white children.

Abstract
OBJECTIVE To study age trends, long-term course and secular changes of bed-sharing practices, and sleep problems among Swiss families. METHODS A total of 493 children were longitudinally followed between 1974 and 2001 by using structured sleep-related interviews at 1, 3, 6, 9, 12, 18, and 24 months after birth and at annual intervals thereafter until 10 years of age. Parents were queried about bed sharing, night wakings, bedtime resistance, and sleep-onset difficulties during the 3 months before each follow-up interview. RESULTS Although in the first year of life relatively few children slept with their parents (<10%), bed sharing increased with age and reached a maximum at 4 years (> or =1 times per week: 38%). Bed sharing of at least once per week was noted in 44% of the children between 2 and 7 years old. Nocturnal wakings also increased from 6 months old to a maximum at 4 years, when more than half of all children woke up at least once per week (22% every night at 3 years). Less than 10% of all children demonstrated frequent bedtime resistance and sleep-onset difficulties. Bed sharing and night wakings during early infancy were not predictive for bed sharing or night wakings during childhood, whereas both bed sharing and night wakings during childhood tended to persist over time. In contrast, bedtime resistance and sleep-onset difficulties seemed to be rather transient phenomena across all ages. No consistent cohort trends were found except for bedtime resistance, which decreased significantly between 1974 and 2001. CONCLUSIONS Bed sharing and nocturnal wakings are common during early childhood. Developmental changes in separation-attachment processes, cognitive capabilities to develop self-recognition and nighttime fears, and motor locomotion may contribute to the particular age trend of night wakings and bed sharing during early childhood.

Abstract
OBJECTIVES Our aim was to estimate the national prevalence of overweight and obesity in Swiss primary schoolchildren and to determine if adiposity is increasing in this age group. METHODS We used a cross-sectional, 3-stage, probability-proportionate-to-size cluster sampling of primary schools throughout Switzerland to obtain a representative national sample of 6-12 year old children (n = 2431). Height and weight were measured and used to calculate body mass index (BMI). BMI references from the U.S. Centers for Disease Control and Prevention (CDC) and the International Obesity Task Force (IOTF) were used to define adiposity. The triceps, biceps, subscapular and suprailiac skinfold thickness (SFT) was measured and used to calculate body fat percentage (BF%). BMI and BF% were compared to data from 6-12 year old Swiss children in the 1960's and 1980's. RESULTS BMI and BF% were well correlated in both boys and girls (r2 = 0.74). Using the IOTF references, the prevalence of overweight and obesity was 16.6% and 3.8% in boys and 19.1% and 3.7% in girls. Using the CDC references, the prevalence of overweight and obesity was 19.9% and 7.4% in boys and 18.9% and 5.7% in girls. There was no significant age or gender difference in the prevalence of overweight or obesity. At all ages, boys and girls had 50-100% higher mean BF% than Swiss children from the 1960's and 1980's. Using the current CDC BMI references, the prevalence of overweight has increased more than 5-fold in Swiss children since the mid-1980's. CONCLUSIONS These findings suggest there has been a striking increase in BF% and the prevalence of overweight and obesity in Swiss children in the last two decades.
