The assessment of left ventricular (LV) dysfunction has become the most frequent indication for echocardiography, a growth that has been driven by the epidemic of heart failure. The value of echocardiography for assessing LV dysfunction is unquestionable, the quantification of both LV systolic and diastolic dysfunction being a reliable indicator of mortality. 1,2 Nonetheless, whereas the ejection fraction and diastolic assessment are important clinical parameters, they are highly dependent on loading and may produce abnormal results under unusual loading conditions. Moreover, in a number of situations where the LV is evaluated, although the overall function is an important finding, the referring clinician is really requesting an assessment of the nature of the underlying myocardial tissue (Table 1). Indeed, in some situations (eg, among family members of patients with a cardiomyopathy) questions arise about the presence of pathology despite the presence of normal ventricular function. Traditionally, it has been difficult to obtain this information because of the lack of sufficiently sensitive parameters, but a number of new developments have shown such success in this area that the clinical application of tools to assess the myocardium in routine practice appears finally to be a realistic proposition.

Stanford Binet: Fourth Edition (SB:IV) assessments have been collected longitudinally for 195 individuals with Down syndrome. This article discusses individual assessments which were selected for their ability to highlight major concerns that practitioners need to consider when interpreting intelligence test scores with this population. In this study, Intelligence Quotient (IQ) changed substantially for many individuals, demonstrating changes in classification from a mild level of intellectual impairment on initial assessment to a severe level on later assessment. Subtests used in calculating composite scores were found to have a dramatic effect on IQ. There was up to 9 IQ points difference depending on whether only the “core” subtests or all subtests used by the assessor were included in the calculations. Thirty-seven percent of the assessments were at “floor level” (i.e., IQ of 36), despite obvious divergent abilities illustrated by age equivalent scores. Mean Age Equivalent (MAE) scores were also problematic as they failed to adequately represent either the range, or divergence, of abilities of the individuals whose data are presented. Directions for future research are discussed.

A correlational study was designed to examine the general processing speed and orthographic processing speed accounts of the association between continuous naming speed and word reading skill in children from fourth to sixth grade. Children were given two tests of each of the following constructs: word reading skill, alphanumeric symbol naming speed, nonsymbol naming speed, alphanumeric processing speed, and nonsymbol processing speed. Results were not completely consistent with either the general processing speed or the orthographic processing speed accounts. Although an alphanumeric symbol processing efficiency component is clearly involved, it is argued that the particularly strong association between naming speed and word reading also reflects the efficiency of phonological processing in children of this age.
