Introduction: Dimercaptosuccinic acid (DMSA) scintigraphy is the gold standard in the evaluation of renal parenchymal defects and is widely used in the pediatric population. As more recent ultrasound equipment was purchased at our tertiary pediatric centre, our objective was to evaluate if renal ultrasound (US) results are equivalent or sufficient when compared to DMSA scintigraphy in the assessment of renal anomalies. Methods: The charts of all 463 patients who underwent DMSA scintigraphy between January 2009 and May 2014 at our pediatric tertiary centre were reviewed. The objective was to look for correlation between US and DMSA scan results for renal scars/dysplasia. A hundred and sixty pediatric patients followed with US and DMSA scan for a total of 285 renal units remained for evaluation after exclusions. Timing of the exams, urinary tract infection (UTI), and indication for imaging were reviewed. Results with older (105 patients) and newer (55 patients) US equipment were compared. Results: Among the 285 renal units evaluated, 39 (14%) had renal parenchymal defects shown by US and 87 (31%) by DMSA scintigraphy (sensitivity 36%, specificity 96%). The DMSA scan was normal for eight abnormal kidneys (3%) on US. The results were not statistically significant when compared to exams performed with newer or older US machines. Conclusions: At our institution, US data are not sensitive enough to give reliable information about renal parenchymal defects, even with newer equipment. DMSA scintigraphy still remains mandatory for the evaluation of renal anomalies, but could be optional if the US exam indicates parenchymal defects.

There is uncertainty regarding the role, if any, of oral contraceptive steroids in the development of focal nodular hyperplasia of the liver. A case of focal nodular hyperplasia of the liver diagnosed by scintigraphy in a 33-year-old woman is presented. The lesion regressed in a dramatic way after oral contraceptive discontinuation. This case report suggests that oral contraceptives may influence the natural history of focal nodular hyperplasia of the liver, and that a trophic effect on the liver lesion is quite possible.

1,2 in addition, the concomitant presence of hypertension and other atherogenic risk factors (arfs) such as diabetes mellitus (Dm) and dyslipidemia increases the risk of caD. 3 myocardial ischemia has been reported to be associated with an increased risk of myocardial infarction (mi) and sudden death in a wide range of patient groups. 4 identification of patients at high risk is thus important for the selection of optimal management strategy in these patients.5 myocardial perfusion imaging (mpi) is an established method for diagnosing and assessing the risk and prognosis of patients with suspected or known caD mostly in Dm. [6][7][8] in a pooled analysis of 39,173 patients with a normal perfusion scan obtained by single photon emission computed tomography (specT) mpi, the annual event rate of cardiac death or mi was 0.6%. in contrast, in studies including 65,655 patients with abnormal results on mpi, the annual event rate was 5.9% per year. studies on the prevalence and severity of abnormal mpi findings in treated hypertensive patients are lacking.The aims of the present cross-sectional study were 3-fold: (1) to provide data on the prevalence

L'article présente de façon détaillée une grille organisant les données souvent fort complexes recueillies auprès des familles recomposées. Il s'adresse aux intervenants. Le cadre théorique, systémique et développemental est présenté brièvement, et la grille est appliquée à une situation. Les différents sous-systèmes sont établis de façon précise, en distinguant ce qui relève de la famille recomposée et des étapes de sa formation et ce qui relève des personnes reliées à la famille, mais externes à sa structure. Les différentes fonctions des sous-systèmes sont clarifiées, avec leurs modalités de réalisation. La grille débouche aisément sur la formulation claire du problème à travailler, de l'objectif à atteindre et de l'engagement de chacun. Enfin, les auteurs présentent brièvement les principales attitudes et techniques qui permettent d'appliquer la grille de façon rapide et efficace
