Introduction. - This study explored concentric and eccentric profile of knee musculature in a jumpers population. Relationships between isokinetic assessment and field tests performances have also been explored. Materials. - Jumpers population presented higher knee flexors performances in concentric and eccentric mode and superior knee extensors strength in eccentric. Significant correlations between isokinetics and field tests results were exclusively observed with athletes quadriceps performances. A very high correlation (r = 0.93) was found between the second bound relative performance of the ten multijumps test and eccentric quadriceps relative peak torque. Conclusion. - Jumpers training may favour a specific muscular development. The knee extensors eccentric strength may be a major factor in the athletic performance. (c) 2005 Elsevier SAS.

Le trouble d’attention avec hyperactivité (ou ADHD-Attention Deficit and Hyperactivity Disorder) se caractérise par [1] un déficit d’attention, [2] une agitation motrice et [3] une impulsivité motrice. Ce trouble présente une prévalence estimée aux environs de 3 à 8% de la population prépubère, avec une nette prédominance masculine. Les conséquences de ce trouble sont importantes et multiples : échec scolaire, difficultés d’apprentissages, mauvaise intégration sociale, … L’hypothèse quant à une étiologie organique de ce trouble trouve un appui considérable dans les études en neuro-imagerie qui ont montré une hypo-activité au niveau des régions frontales, du striatum et d’une partie du système dopaminergique. Les études neuropsychologiques vont également dans ce sens en montrant une similarité entre les profils cognitifs de ces enfants et de patients frontaux. Toutefois, malgré une meilleure compréhension du trouble, le diagnostic d’ADHD reste encore difficile et repose le plus souvent sur le recueil de données subjectives (entretien avec les parents, …). Le but de notre étude est d’une part d’objectiver les déficits attentionnels et exécutifs chez des enfants ADHD de 6 à 12 ans, et d’autre part d’identifier les épreuves neuropsychologiques les plus sensibles aux troubles présentés par ces enfants. Nous avons administré à 17 enfants ADHD et 17 enfants de contrôle (appariés sur base de l’âge et du sexe) des tâches [i] attentionnelles (attention soutenue, sélective et divisée) de la TEA et [ii] exécutives (inhibition évaluée par le test de Stroop, de la Statue [NEPSY] et Go/No Go [TEA] ; test de flexibilité cognitive [TEA] et épreuve de planification [NEPSY]). Les analyses de comparaison de moyennes montrent qu’au niveau attentionnel, les enfants ADHD présentent des troubles d’attention sélective visuelle et auditive (p<.05) ainsi que de l’attention soutenue (p<.05). Au niveau exécutif, on constate des difficultés de flexibilité cognitive et d’inhibition (p<0.01). Une analyse discriminante (par régression logistique) a également été réalisée afin de déterminer la sensibilité/spécificité de ces épreuves dans le diagnostic de l’ADHD. Les analyses permettent de montrer que c’est l’association de deux mesures d’inhibition (test de Statue et Go/No Go) qui permet d’avoir la meilleure sensibilité/spécificité (respectivement de 80% et 87,5%). Ces résultats préliminaires soulignent la contribution importante que peuvent apporter les tests neuropsychologiques dans le diagnostic de l’ADHD. Plus spécifiquement, ils permettent de préciser la nature des déficits attentionnels et exécutifs chez les enfants ADHD : troubles de l’attention soutenue et de l’attention sélective d’une part, et troubles de l’inhibition et de la flexibilité cognitive d’autre part.

AIM: A Belgian registry for pediatric Crohn's disease, BELCRO, was created. This first report aims at describing disease presentation and phenotype and determining associations between variables at diagnosis and registration in the database. METHODS: Through a collaborative network, children with previously established Crohn's disease and newly diagnosed children and adolescents (under 18 y of age) were recruited over a 2 year period. Data were collected by 23 centers and entered in a database. Statistical association tests analyzed relationships between variables of interest at diagnosis. RESULTS: Two hundred fifty-five patients were included. Median age at diagnosis was 12.5 y (range: 1.6-18 y); median duration of symptoms prior to diagnosis was 3 m (range: 1-12 m). Neonatal history and previous medical history did not influence disease onset nor disease behavior. Fifty three % of these patients presented with a BMI z-score < -1. CRP was an independent predictor of disease severity. Steroids were widely used as initial treatment in moderate to severe and extensive disease. Over time, immunomodulators and biological were prescribed more frequently, reflecting a lower prescription rate for steroids and 5-ASA. A positive family history was the sole significant determinant for earlier use of immunosuppression. CONCLUSION: In Belgium, the median age of children presenting with Crohn's disease is 12.5 y. Faltering growth, extensive disease and upper GI involvement are frequent. CRP is an independent predictive factor of disease activity. A positive family history appears to be the main determinant for initial treatment choice. [less ▲]

Introduction: Soluble cytokine receptors (sCRs) modulate the in vivo activity of cytokines. Deficient sCR production could participate in the pathogenesis and course of Crohn's disease ( CD). The aim of the study was to examine the profile of sCRs in CD patients and their modulation by infliximab and corticosteroids. Methods: We prospectively examined active CD patients (aCD) treated with either infliximab (n=21) or corticosteroids (n=9), CD patients in clinical remission (rCD, n=20), ulcerative colitis patients (UC, n=24), and healthy subjects (HS, n=15). Cultures of colonic biopsies were also examined from CD inflamed (n=8), CD non-inflamed (n=7), and healthy mucosa (n=8). Levels of tumour necrosis factor alpha (TNF-alpha), soluble TNF receptor I (sTNFRI), soluble TNF receptor II (sTNFRII), interleukin 1 beta (IL-1 beta), soluble IL-1 receptor I (sIL-1RI), soluble IL-1 receptor II (sIL-1RII), IL-6, soluble IL-6 receptor (sIL-6R), and sgp130 were measured using ELISA. Results: Higher levels of sTNFRI (p<0.05, p<0.01), sTNFRII (p<0.01, p<0.01), sIL-1RI (p<0.05, NS), IL-6 (p<0.01, p<0.01), and sIL-6R (p<0.05, NS) were observed in aCD compared with rCD and HS. Interestingly, sIL-1RII (p<0.05, p<0.01) and sgp130 (p<0.01, p<0.01) were profoundly decreased in aCD compared with rCD and HS, and were negatively correlated with CRP. Deficient production of sIL-1RII was specific to CD ( not observed in ulcerative colitis), and was further confirmed at the mucosal level. Infliximab decreased sTNFRII at one and four weeks (p<0.05) and enhanced sIL-6R levels at one week (p<0.05). Corticosteroids increased sIL-1RII levels at one week (p<0.05). Conclusion: CD is associated with dysregulated production of sCRs. Deficiency in sIL-1RII and sgp130 may be essential to CD pathogenesis. Their replacement through the use of fusion proteins could represent future alternative therapeutic strategies for CD. [less ▲]

Prior to Professor van der Laan's enquiry, in the March 1988 issue of the Messenger, on the general interest among astronomers from the European community to possibly participate in Key Programmes (KPs) at the European 80uthern Observatory, at least three distinct groups (including more than half of the above authors) were already involved in the study of "gravitational lensing" effects (see box on pages 10-11). Observations were being performed with the help of various telescopes on La 8illa as weil as at other observatories (VLA, CFHT, Palomar, Kitt Peak, etc.). [less ▲]

Stratospheric volume mixing ratio profiles of chlorine nitrate (ClONO2) have been retrieved from 0.01-cm−1 resolution infrared solar occultation spectra recorded at latitudes between 14°N and 54°S by the atmospheric trace molecule spectroscopy Fourier transform spectrometer during the ATLAS 1 shuttle mission (March 24 to April 2, 1992). The results were obtained from nonlinear least squares fittings of the ClONO2 v 4 band Q branch at 780.21 cm−1 with improved spectroscopic parameters generated on the basis of recent laboratory work. The individual profiles, which have an accuracy of about ±20%, are compared with previous observations and model calculations. [less ▲]
