Overweight and eating disorders in primary care: a sentinella reporting in 2-20 years old patients

Aims: To describe overweight or eating disorders in primary care consultations of Swiss children or adolescents and analyze responses by physicians. Methods: 150 to 200 primary care physicians participating in the Swiss Sentinel Surveillance Network in collaboration with the Swiss Federal Office of Public Health register their consultations over one year for selected health conditions. We describe reports of consultations where overweight or eating disorders were identified in subjects aged 2-20 years by physicians, patients or their relatives, or referring professionals, between 29.12.2007 and 15.2.2008. Results: 189 consultations were registered in the first 7 weeks of declaration. A short majority concerned female (58%) and 12-20 years old (53%) patients. Half were reported by pediatricians, one third by general practitioners and the remaining minority by internists. The sample included two thirds of Swiss-German and one third of Swiss-French cases. In the male subgroup aged 2-20 and in female children aged 2-11, almost all reported consultations were characterized by overweight. Among female teenagers, underweight was reported in 29% whilst overweight was recorded in 60%. Anorexia was noted in 68% of reported consultations of underweight female teenagers. In underweight patients, advice given by physicians frequently covered both nutrition and physical activity (38%) or nutrition only (29%), while no specific recommendations were recorded for the remaining third. In case of overweight, for one half of consultations patients received both nutritional and physical activity recommendations, for 12% nutritional only, and for one quarter patients were not advised in these domains. No specific treatment was usually proposed to overweight patients (65%), except when bulimia was diagnosed; in such case, one third of patients were proposed a psychological/psychiatric treatment, whereas both psychological and pharmacological treatments were frequently offered for underweight teenagers. Therapy was most often motivated by physicians (50%) or by relatives (44%), more rarely by patients themselves (7%). Conclusions: These preliminary data indicate that in some primary care consultations of young patients with overweight or eating disorders, advice was not given on nutrition and physical activity. This observation needs to be later confirmed with the totality of the consultations registered in 2008 and reasons will be further investigated.

Toxoplasmosis during pregnancy and infancy. A new approach for Switzerland.

In recent years it has become evident that screening for and treatment of acute toxoplasmosis during pregnancy may have no measurable impact on vertical transmission and neonatal morbidity and mortality. A broad lack of evidence with regard to many aspects of congenital toxoplasmosis has been recognised in a common European initiative (EUROTOXO) which reviewed several thousand published papers on the subject of toxoplasmosis during pregnancy and childhood. It was therefore clear that the strategies currently implemented in our country would, on closer inspection, no longer withstand the claim for evidence-based procedures. The arguments and call for a change of paradigm in Switzerland which follow here are the result of a national consensus-finding process involving experts from various specialities, including gynaecology/obstetrics, paediatrics/neonatology, infectiology, ophthalmology and laboratory medicine, together with representatives of the public health authorities.

Body composition using bio-impedance analysis in pediatric patients with inflammatory bowel disease. Corcordance with dual energy X-ray absorptiometry and comparison with healthy controls

Introduction: Growth is a central process in paediatrics. Weight and height evaluation are therefore routine exams for every child but in some situation, particularly inflammatory bowel disease (IBD), a wider evaluation of nutritional status needs to be performed. Objectives: To assess the accuracy of bio-impedance analysis (BIA) compared to the gold standard dual energy X-ray absorptiometry (DEXA) in estimating percentage body fat (fat mass; FM) and lean body mass (fat free mass; FFM) in children with inflammatory bowel disease (IBD). To compare FM and FFM levels between patients with IBD and healthy controls. Methods: Twenty-nine healthy controls (12 females; mean age: 12.7 ± 1.9 years) and 21 patients (11 females; 14.3 ± 1.3 years) were recruited from August 2011 to October 2012 at our institution. BIA was performed in all children and DEXA in patients only. Concordance between BIA and DEXA was assessed using Lin's concordance correlation and the Bland-Altman method. Between-group comparisons were made using analysis of variance adjusting for age. Results: BIA-derived FM% showed a good concordance with DEXA-derived values, while BIA-derived FFM% tended to be slightly higher than DEXA-derived values (table). No differences were found between patients and controls regarding body mass index (mean ± SD: 19.3 ± 3.3 vs. 20.1 ± 2.8 kg/m2, respectively; age-adjusted P = 0.08) and FM% (boys: 25.3 ± 10.2 vs. 22.6 ± 7.1%, for patients and controls, respectively; P = 0.20; girls: 28.2 ± 5.7 vs. 26.4 ± 7.7%; P = 0.91). Also, no differences were found regarding FFM% in boys (74.9 ± 10.2 vs. 77.4 ± 7.1%; P = 0.22) and girls (71.8 ± 5.6 vs. 73.5 ± 7.7%; P = 0.85). Conclusion: BIA adequately assesses body composition (FM%) in children with IBD and could advantageously replace DEXA, which is more expensive and less available. No differences in body composition were found between children with IBD and healthy controls.

Exposition des enfants à la fumée passive: le point sur des campagnes de sensibilisation

Enfants de moins de 10 ans fumant passivement 14 cigarettes ! D'avril 2010 à avril 2011, l'exposition de 148 enfants (81 garçons et 67 filles) a été testée: 10 enfants de moins d'un an, 25 de 1 à 5 ans, 19 de 5 à 10 ans, 30 de 10 à 15 ans et 64 de 15 à 18 ans. 10 d'entre eux sont des fumeurs et la plus jeune de 14 ans fume 10 cigarettes par jour. Leurs parents, ou parfois des jeunes eux-mêmes, ont commandé de manière volontaire, via les sites Internet des CIPRET Valais, Vaud et Genève, un badge MoNIC gratuit. Les résultats quant à l'exposition de ces enfants interpellent et méritent l'attention.Pour l'ensemble des enfants, la concentration moyenne de nicotine dans leur environnement intérieur mesurée via les dispositifs MoNIC est de 0,5 mg/m3, avec des maximums pouvant aller jusqu'à 21 mg/m3. Pour le collectif d'enfants âgés de moins de 10 ans (26 garçons et 28 filles; tous non-fumeurs), la concentration de nicotine n'est pas négligeable (moyenne 0,069 mg/m3, min 0, max 0,583 mg/m3). En convertissant ce résultat en équivalent de cigarettes inhalées passivement, nous obtenons des chiffres allant de 0 à 14 cigarettes par jour* avec une moyenne se situant à 1.6 cig/j. Encore plus surprenant, les enfants de moins d'un an (4 garçons et 6 filles) inhalent passivement, dans le cadre familial, en moyenne 1 cigarette (min 0, max 2.2). Pour les deux autres collectifs: 10-15 ans et 15-18 ans, les valeurs maximales avoisinent les 22 cigarettes. Notons cependant que ce résultat est influencé, ce qui n'est pas le cas des enfants plus jeunes, par le fait que ces jeunes sont également parfois des fumeurs actifs.* Quand la durée d'exposition dépassait 1 jour (8 heures), le nombre d'heures a toujours été divisé par 8 heures. Le résultat obtenu donne l'équivalent de cigarettes fumées passivement en huit heures. Il s'agit de ce fait d'une moyenne, ce qui veut dire que durant cette période les enfants ont pu être exposés irrégulièrement à des valeurs supérieures ou inférieures à cette moyenne. [Auteurs]

Mechanical ventilation in the newborn; a simplified approach. Part 1: Intermittent positive pressure ventilation.

Positive pressure ventilation (PPV) is a frequent intervention in the neonatal intensive care unit. This article is directed towards paediatricians in training and attempts to cover the basics of PPV without being too technical. To do so we have employed an extensive use of graphics to illustrate the underlying principles.

Gastrostomies, PEG, sondes et boutons: pour ne plus les confondre et savoir les gérer!

On confond trop souvent le mode de confection des gastrostomies avec le nom de l'équipement du conduit. Ainsi combien de fois avons-nous été appelés pour avis sur une « PEG » qui en fait était une gastrostomie équipée d'un bouton. Le but de ce travail est de clarifier les problèmes de techniques de gastrostomies chez l'enfant, les équipements à disposition et d'évoquer les problèmes qui s'y rapportent.

Mechanical ventilation in the newborn; a simplified approach. Part 2: High-frequency ventilation.

High frequency oscillatory ventilation (HFOV) is becoming an increasingly popular intervention in the neonatal intensive care unit. This article will attempt to explain the principles of HFOV. It is inherently more difficult to become skilled in this technique than in other forms of mechanical ventilation, so caution is warranted.
