Fractional flow reserve (FFR) during invasive coronary angiography has become an established tool for guiding treatment. However, only one-third of intermediate-grade coronary artery stenosis (ICAS) are hemodynamically significant and require coronary revascularization. Additionally, the severity of stenosis visually established by coronary computed tomography angiography (CCTA) does not reliably correlate with the functional severity. Therefore, additional angiographic morphologic descriptors affecting hemodynamic significance are required. To evaluate quantitative stenosis analysis and plaque descriptors by CCTA in predicting the hemodynamic significance of ICAS and to compare it with quantitative catheter coronary angiography (QCA). QCA was performed in 65 patients (mean age 63 ± 9 years; 47 men) with 76 ICAS (40–70 %) on CCTA. Plaque descriptors were determined including circumferential extent of calcification, plaque composition, minimal lumen diameter (MLD) and area, diameter stenosis percentage (Ds %), area stenosis percentage and stenosis length on CCTA. MLD and Ds % were also analyzed on QCA. FFR was measured on 52 ICAS lesions on CCTA and QCA. The diagnostic values of the best CCTA and QCA descriptors were calculated for ICAS with FFR B 0.80. Of the 76 ICAS on CCTA, 52 (68 %) had a Ds % between 40 and 70 % on QCA. Significant intertechnique correlations were found between CCTA and QCA for MLD and Ds % (p\0.001). In 17 (33 %) of the 52 ICAS lesions on QCA, FFR values were B0.80. Calcification circumference extent (p = 0.50) and plaque composition assessment (p = 0.59) did not correlate with the hemodynamic significance. Best predictors for FFR B 0.80 stenosis were B1.35 mm MLD (82 % sensitivity, 66 % specificity), and B2.3 mm2 minimal lumen area (88 % sensitivity, 60 % specificity) on CCTA, and B1.1 mm MLD (59 % sensitivity, 77 % specificity) on QCA. Quantitative CCTA and QCA poorly predict hemodynamic significance of ICAS, though CCTA seems to have a better sensitivity than QCA. In this range of stenoses, additional functional evaluation is required. [less ▲]

Carnitine palmitoyltransferase II (CPT2) deficiency is a rare inborn error of mitochondrial fatty acid metabolism associated with various phenotypes. Whereas most patients present with postnatal signs of energetic failure affecting muscle and liver, a small subset of patients presents antenatal malformations including brain dysgenesis and neuronal migration defects. Here, we report recurrence of severe cerebral dysgenesis with Dandy-Walker malformation in three successive pregnancies and review previously reported antenatal cases. Interestingly, we also report that acylcarnitines profile, tested retrospectively on the amniotic fluid of last pregnancy, was not sensitive enough to allow reliable prenatal diagnosis of CPT2 deficiency. Finally, because fetuses affected by severe cerebral malformations are frequently aborted, CPT2 deficiency may be underestimated and fatty acid oxidation disorders should be considered when faced with a fetus with Dandy-Walker anomaly or another brain dysgenesis.

Background: Bedside clinical examinations can have high rates of misdiagnosis of unresponsive wakefulness syndrome (vegetative state) or minimally conscious state. The diagnostic and prognostic usefulness of neuroimaging-based approaches has not been established in a clinical setting. We did a validation study of two neuroimaging-based diagnostic methods: PET imaging and functional MRI (fMRI). Methods: For this clinical validation study, we included patients referred to the University Hospital of Liège, Belgium, between January, 2008, and June, 2012, who were diagnosed by our unit with unresponsive wakefulness syndrome, locked-in syndrome, or minimally conscious state with traumatic or non-traumatic causes. We did repeated standardised clinical assessments with the Coma Recovery Scale—Revised (CRS—R), cerebral 18F-fluorodeoxyglucose (FDG) PET, and fMRI during mental activation tasks. We calculated the diagnostic accuracy of both imaging methods with CRS—R diagnosis as reference. We assessed outcome after 12 months with the Glasgow Outcome Scale—Extended. Findings: We included 41 patients with unresponsive wakefulness syndrome, four with locked-in syndrome, and 81 in a minimally conscious state (48=traumatic, 78=non-traumatic; 110=chronic, 16=subacute). 18F-FDG PET had high sensitivity for identification of patients in a minimally conscious state (93%, 95% CI 85—98) and high congruence (85%, 77—90) with behavioural CRS—R scores. The active fMRI method was less sensitive at diagnosis of a minimally conscious state (45%, 30—61) and had lower overall congruence with behavioural scores (63%, 51—73) than PET imaging. 18F-FDG PET correctly predicted outcome in 75 of 102 patients (74%, 64—81), and fMRI in 36 of 65 patients (56%, 43—67). 13 of 42 (32%) of the behaviourally unresponsive patients (ie, diagnosed as unresponsive with CRS—R) showed brain activity compatible with (minimal) consciousness (ie, activity associated with consciousness, but diminished compared with fully conscious individuals) on at least one neuroimaging test; 69% of these (9 of 13) patients subsequently recovered consciousness. Interpretation: Cerebral 18F-FDG PET could be used to complement bedside examinations and predict long-term recovery of patients with unresponsive wakefulness syndrome. Active fMRI might also be useful for differential diagnosis, but seems to be less accurate.

Cette contribution questionne la fiabilité du diagnostic précoce des troubles du comportement externalisé chez l’enfant. Les données concernant le comportement de 118 enfants ont été collectées par questionnaires et observation auprès de leurs parents, leurs enseignants et les cliniciens lors du recrutement et après 12 mois. Les résultats montrent des variations importantes dans le nombre d’enfants atteignant un seuil clinique selon l’informateur et la méthode considérés. Une méthode combinant les évaluations des informateurs pour obtenir un diagnostic valide est éprouvée. Les résultats plaident en faveur d’une procédure multi-informateurs et multiméthodes dont les implications sont discutées sur le plan clinique et de la recherche. [less ▲]

A l’aube de l’actualisation du SDER, la CPDT a reçu la mission de dresser le diagnostic territorial de la Wallonie. Cette publication présente ce diagnostic et s’articule en trois grandes parties. La première partie aborde six défis majeurs pour l'avenir - le défi démographique, le défi climatique, le défi énergétique, le défi de la compétitivité, le défi de la cohésion sociale et le défi de la mobilité- et envisage dans une approche prospective comment le territoire sera impacté par ces changements. La seconde partie du diagnostic vise à estimer les besoins spatiaux des grands secteurs occupant et dynamisant le territoire. Une analyse fine permet de dégager ces besoins sur la base des structures héritées mais aussi d’extrapoler les enjeux de leur adaptation aux grands défis. Dans la troisième partie, le diagnostic se penche sur l’intégration des besoins sectoriels à l’espace wallon. L’examen des dimensions spatiales permet de conclure le diagnostic de manière transversale et territoriale. La première dimension concerne l'insertion de la Wallonie dans l’Europe des Régions et dégage les principaux enjeux vis-à-vis des projets européens et des régions voisines. Une autre dimension a pour objet la structure spatiale interne de la Wallonie et interroge ses pôles et ses aires de pertinences. Enfin, le diagnostic examine la question des spécificités et des relations entre villes et campagnes en Wallonie. [less ▲]
