Abnormal spatial selection and tracking in children with amblyopia.

We assessed 18 children with unilateral amblyopia and 30 age-matched controls on one low-level and three high-level motion tasks. Children with amblyopia showed similar performance to controls in both amblyopic and fellow eyes on a low-level global motion task and on a high-level 2-dot apparent motion task. Performance on both single-object and multiple-object attentive tracking tasks was significantly depressed in both amblyopic and fellow eyes relative to controls. These findings suggest that binocular regions of posterior parietal cortex likely contribute to a deficit in voluntary, spatial attention that is a component of amblyopia.

Parents who report using illicit drugs: findings and implications from the DRUGNET study.

In recent years, a national discussion has emerged concerning what parents should tell their children about their own past drug use. DRUGNET is an ongoing, on-line survey of successful, healthy, adults who occasionally use illicit drugs. This paper reviews data from a subset of this survey, namely, those respondents who were parents with self-reported use of at least one illicit drug. The sample (n = 325) was predominantly white men who reported having above average education and household incomes. Their mental health as measured by the General Well-being Schedule was similar to the national norm. Respondents reported using drugs to manage parental stress and expressed concerns over how to communicate with their children and legal risks related to their own drug use. The limitations and the implications of these data are discussed.

Coronary bypass surgery. Value of maximal exercise testing in assessment of results.

To evaluate the relationship of results of maximal treadmill testing and results of saphenous vein bypass surgery (SVG), 30 patients underwent a maximal treadmill test before and after SVG; an additional 39 had results of postoperative exercise testing available. These patients were part of a group of 91 patients (95% of 96 survivors) who had complete right- and left-heart catheterizations and coronary angiography before and after operation. Twenty-one per cent had improved ejection fractions postoperatively; in 32% ejection fractions were worse. Duration of maximal treadmill exercise correlated poorly with ejection fraction changes or graft patency. Rate-pressure product (RPP) was usually lower postoperatively in patients with worse ejection fractions, primarily because of a low systolic blood pressure at maximum exercise. RPP postoperatively of less than 25,000 almost always meant poor surgical results, either graft occlusion or poor left ventricular function, while RPP of more than 30,000 meant that left ventricular function was preserved and all grafts or the graft to the anterior descending were patent. Thus, success or failure of SVG in these groups may be predicted without postoperative catheterization. An open graft to the anterior descending coronary generally insured a high RPP with exercise, even if other grafts were closed, as long as ventricular function remained good.
