Le développement des activités sportives augmente la fréquence des lésions musculo-squelettiques de l’adolescent. Ces lésions dépendent non seulement du mécanisme mais également de l’âge du sportif et de sa maturation osseuse, particulièrement des noyaux d’ossification. Les aphophysoses, ostéochondroses ou ostéodystrophies se manifestent par une douleur au niveau de l’insertion tendineuse sur le noyau d’ossification secondaire en croissance. Elles sont souvent provoquées par des contraintes en traction-cisaillement chez des enfants sportifs entre 3 et 16 ans. L’excès pondéral constitue également un facteur de risque. La guérison spontanée s’observe généralement après trois à 12, voire 18 mois d’évolution. La maladie de Sever est l’ostéodystophie du pied la plus fréquente ; elle touche le noyau postérieur du calcanéum, qui apparaît entre sept et dix ans et qui fusionne à la fin de la puberté (16–18 ans) et sur lequel s’insèrent le tendon d’Achille et le court fléchisseur plantaire. Les contraintes en traction et compression (réception de saut) sont importantes à ce niveau surtout chez les sportifs de sept à 15 ans pratiquant diverses impulsions (basket-ball, volley-ball, saut en longueur. . . ). La talalgie se manifeste lors de la pratique sportive. La douleur est bilatérale dans 60% des cas. Il faut rechercher des troubles de statique plantaire (pieds creux) régulièrement associés à la maladie de Sever. Le bilan radiologique reste souvent décevant et peu spécifique. Le diagnostic différentiel doit s’établir avec une tendinopathie achilléenne, une fracture du calcaneus, un kyste osseux, un ostéome ostéoïde, une ostéomyélite ou une éventuelle enthésopathie (spondylarthropathie). La base du traitement est le repos sportif en phase algique, l’usage de la cryothérapie, le port de talonnettes amortissantes ou encore la prise temporaire d’AINS (ibuprofène). Au niveau du genou, l’apophysose de croissance la plus fréquente est la maladie d’Osgood-Schlatter qui est plus fréquente chez les adolescents pratiquant des sports de sauts. Au niveau du bassin tous les noyaux d’ossifications peuvent être atteints et même être le site de fractures-avulsions lors de contractions musculaires excessives ou brutales car le cartilage de croissance présente une faiblesse locale par rapport aux structures musculo-tendineuses. L’ostéochondrite disséquante correspond à un noyau osseux séparé du corps de l’os et recouvert de cartilage normal ; localisée à la partie supéromédiale du talus ou au niveau des condyles fémoraux. Elle est souvent asymptomatique, voire entraine une discrète limitation douloureuse de la mobilisation mais entraine une douleur à la palpation locale. Elle nécessite cependant un traitement adéquat. En cas de lésion peu ou pas évolutive, une surveillance radiologique (IRM / arthroscanner) est suffisante. Chez le très jeune adolescent une immobilisation plâtrée de six semaines permettrait la fusion du noyau (au niveau du dôme talien). L’arthroscopie sera justifiée en cas de séquestre osseux afin de l’extraire, et ce, avec de bons résultats postopératoires. L’ostéosynthèse d’un noyau volumineux peut être également indiquée, les résultats restant plus aléatoires. En conclusion, la pathologie traumatique ou microtraumatique de l’adolescent sportif n’est pas rare et ne doit jamais être négligée. Toute douleur exige une exploration radiologique comparative afin de poser un diagnostic précis et d’entreprendre un traitement adéquat, le plus souvent conservateur. [less ▲]

From 1992 to 1995, dead seabirds found on Belgian beaches were collected and various tissues of 241 birds were sampled for histopathological, bacteriological, parasitological, and toxicological investigations. The most common species examined was the guillemot (Uria aalge). Necropsies revealed cachexia (severe emaciation), acute haemorrhagic gastro-enteropathy and oil contamination in many of these birds. Statistical analyses were performed in order to explore correlations of these with biological parameters such as age, sex, and origin (pelagic or non-pelagic). The pelagic origin of seabirds were associated with the three main findings. Oil contamination was associated with acute gastro-enteropathy and cachexia, and cachexia was more prevalent among juveniles. Finally, cachexia and acute gastro-enteropathy were strongly associated. It is possible that oiled pelagic seabirds become cachectic and die of acute gastro-enteropathy. (C) 1997 International Council for the Exploration of the Sea. [less ▲]

Animal performance, composition and quality of meat from Belgian Blue bulls either fattened indoors (FI) or finished indoors after a previous grazing period were studied during six years. During the grazing period, three intensification managements were tested on a permanent pasture conducted as set stocking. The intensification levels were either high (HN:140 kg N(.)ha(-1) with 6 bulls(.)ha(-1)) or moderate with a 33% reduction of nitrogen fertilisation but with the same stocking rate (MN:93 kg N(.)ha(-1), 6 bulls(.)ha(-1)) or low with no nitrogen fertiliser but with a reduced stocking rate (ON, 4 bulls(.)ha(-1)). The levels of intensification did not affect sward characteristics and chemical composition of the grass. The apparent nitrogen efficiency per ha was larger in the ON plot than in the HN and MN plots ( 26 vs. 14%). The average daily gain of bulls during the grazing season was similar in the three groups at 1.0 kg(.)d(-1). The bulls from the FI group were characterised by average daily gains significantly higher than the bulls which were previously grazed and then finished indoors (1.5 vs. 1.2 kg(.)d(-1); P < 0.01). The slaughter weight, the carcass composition, the dressing percentage and most of the meat quality parameters were similar between the treatment groups. The inclusion of a grazing period in the fattening system produced a meat which was darker (lower L*, P < 0.01), more red (higher a*, P < 0.05) and had a higher content of linolenic acid (C18:3 n-3) than that of the animals fattened indoors.

Narrow diameter implants (NDIs) are increasingly produced and used in implant dentistry especially since the introduction of new and more resistant materials. The objective of the present study was to evaluate the clinical performance of NDIs (3.3 mm) placed in thin alveolar crests. Methods: Twenty consecutive patients needing implant-supported fixed partial dentures and presenting an alveolar thickness ≤ 6 mm were treated with one or several NDIs. The surgical protocol was chosen according to the clinical situation: °1 flapless; °2 mini-cervical flap; 3° wide flap; 4° wide flap + guided bone regeneration (GBR). Implants were immediately loaded if the primary stability was higher than 20 Ncm. Implant survival and success, prosthodontic success rates and patient-centered outcomes were evaluated after a follow-up period of 1 year. Results: A total of 39 implants were placed in 20 patients, 12 and 27 implants in the anterior regions and in the posterior mandible, respectively. All implants but one reached an insertion torque higher than 20 Ncm and were loaded within 48 hours. The implant survival and success rates both reached 94.7 %. The need for GBR was avoided in 60 % of the implant sites. The mean peri-implant bone remodeling after a follow-up period of 1 year was -0.35 mm at the implant level. Peri-implant bone remodeling was higher in the posterior region, when the alveolar crest was thinner than 4 mm and GBR was required in addition.Conclusion: The use of NDIs to restore partial edentation in sites with limited horizontal bone thickness seems to be an effective treatment option that prevented GBR in the majority of the present cases. Immediate provisionalization of NDIs does not seem to impair the results. [less ▲]

This study examined whether young children are influenced by the subjective experience associated with an easy or difficult recall when making memory decisions. Seventy-one children, aged 4, 6, and 8 years, were asked to generate either a small (easy condition) or large (hard condition) number of first names. Statistical analyses revealed that participants in the hard condition were more likely to infer that they did not know many names than participants in the easy condition, contrary to what would be expected if children based their memory judgement on the objective number of recalled items. Overall, our results support the hypothesis that children as young as 4 years old rely on the subjective experience of ease to regulate their decision-making processes. Theoretical implications of these findings are discussed. [less ▲]

Busulfan is commonly used in preparative conditioning regimens prior to hematopoietic stem cell transplantation in children and young adults for malignant and non-malignant disorders. For many years Busulfan was only available in an oral form, resulting in large inter- and intra-patients variability in plasma exposure, associated with higher graft failure rate as well as higher toxicity such as venoocclusive disease. With the development of an intravenous formulation of Busulfan, a more accurate control of both the inter- and intra-patient variability has been provided. The goal of this study was to evaluate the use and efficacy of intravenous Busulfan in comparison with the oral formulation in children undergoing an autologous transplantation after conditioning with Busulfan. Despite the small number of patients, this study confirmed the apparent benefit of intravenous Busulfan in children undergoing an autologous HSCT. The use of a 5-level dose schedule defined by body weight resulted in an efficient engraftment with marked reduction in the incidence of veno-occlusive disease compared with oral Bu. In terms of diseasefree outcome, survival and event-free survival, similar results have been obtained in both groups. The choice of this formulation of Busulfan should therefore be considered.
