[Q]: The Tonnis radiographic classification of developmental dysplasia of the hip (DDH) has been used as a prognostic indicator for patients with walking-age DDH. The International Hip Dysplasia Institute (IHDI) classification, a new radiographic classification system, has been proposed to be more reliable by its creators. We sought to validate its reliability using independent observers, to compare it to the Tonnis method, and to assess its prognostic significance in a large cohort of patients.', 'A consecutive series of walking-age DDH patients were examined radiographically and classified by the Tonnis and IHDI schemes by 3 independent observers. Interobserver agreement was determined using the Kappa method. Clinical data were collected on patients with regard to success of closed reduction, need for later pelvic osteotomy, and presence of subsequent radiographic avascular necrosis (AVN). The prognostic value of the Tonnis and IHDI classifications to predict these clinical outcomes was determined.', 'A total of 287 hips were available for analysis of the classification schemes. In total, 235 hips underwent attempted closed reduction and were eligible for analysis of successful closed reduction, and 131 hips had >4-year follow-up and were utilized for analysis of late pelvic osteotomy and AVN. Both classifications showed excellent interobserver reliability and in general, there was nonstatistically significant better reliability for the IHDI versus the Tonnis classification. In multivariate analysis, both IHDI and Tonnis classifications were found to be predictive of successful closed reduction and need for late pelvic osteotomy. Both methods showed trends toward being predictive of AVN rate, without statistical significance.

[Q]: B-type natriuretic peptide (BNP) and N-terminal-pro-BNP (NT-pro-BNP) are important diagnostic tools for patients with suspected cardiac disorders. The aim of this study was to evaluate the predictive value of plasma NT-pro-BNP in identifying cardiac metastases in patients with non-small cell lung cancer (NSCLC) and dyspnoea.', 'A total of 120 patients, median age 62 years (range 46-83), with NSCLC and dyspnoea were studied. Patients with heart failure or documented coronary artery disease were excluded. Echocardiographic imaging was used to detect cardiac metastases and estimate global left ventricular function. Ejection fraction and E/A ratio from transmitral inflow pattern were calculated. Plasma NT-pro-BNP was also measured. 72 patients (72/120, 60%) with cardiac metastases were identified.', 'NT-pro-BNP was significantly higher in patients with metastases (1347.5 +/- 1004.30 pg/ml vs. 159.02 +/- 93.29 pg/ml; p = 0.001). No differences between groups, regarding s-creatinine (p = 0.45), haemoglobin (p = 0.71), left ventricular hypertrophy (p = 0.91), and diastolic dysfunction (p = 0.79), were observed.

[Q]: The majority of studies assessing executive function in attention deficit disorder (ADD) have shown deficits in attentional set shifting using either the Wisconsin card sorting task or the intra-dimensional/extra-dimensional set-shifting task (ID/ED). Damage to the prefrontal cortex in humans, primates, and rodents impairs extra-dimensional (ED) shifts. Noradrenergic depletion of the medial prefrontal cortex in rats is sufficient to impair attentional set shifting. Atomoxetine, a selective norepinephrine (NE) re-uptake inhibitor, is hypothesized to produce beneficial effects in patient with ADD by augmenting NE release in prefrontal cortex.', 'We assessed the effects of systemic administration of atomoxetine (0.0, 0.1, 0.3, and 0.9 mg/kg/ml) in normal and noradrenergically lesioned (NE-LX) rats on attentional-set shifts. We replicated findings showing NE-LX rats are selectively impaired on the ED shifts but not reversals or other discriminations.', 'Atomoxetine remediated the attentional set-shifting impairments in NE-LX rats but impaired ED performance of non-lesioned rats.
