Office laboratory procedures, office economics, parenting and parent education, and urinary tract infection.

We again review four areas of interest to office-based pediatricians: office laboratory procedures, office economics, parenting and patient education, and urinary tract infections. Sean Elliott provides an update on the Clinical Laboratories Improvement Amendments (CLIA) and their impact of office practice. Eve Shapiro reviews office economics, focusing on measuring quality of care, use of performance data, costs of new technologies, and the impact of managed care on the medical marketplace. John Walter offers an update on parenting and parent education, with approaches to counseling families about overuse of antibiotics, teen pregnancy, hyperactivity, violence, and asthma. Richard Wahl reviews the recent research on urinary tract infection, with special attention paid to office diagnosis and management, longitudinal studies of children with urinary tract infections, and the controversy surrounding the American Academy of Pediatrics Task Force on Circumcision report.

Angiostatin binds to smooth muscle cells in the coronary artery and inhibits smooth muscle cell proliferation and migration In vitro.

Angiostatin is an inhibitor of angiogenesis that is known to reduce endothelial cell proliferation and consequently prevent the progression of tumor metastases. However, the modest effect of angiostatin on endothelial cell proliferation raises the possibility that angiostatin might exert its effects on other cells. To determine the cellular distribution of angiostatin binding in tissues with neovasculature (atherosclerotic coronary arteries), we developed a fusion protein consisting of placental alkaline phosphatase and the first 3 kringles of plasminogen. Angiostatin binding colocalized with smooth muscle cells and could be inhibited by a 50-fold molar excess of plasminogen and 10 mmol/L epsilon-amino-n-caproic acid. The fusion protein also bound to smooth muscle cells in culture. Angiostatin inhibited hepatocyte growth factor-induced proliferation and migration of smooth muscle cells, suggesting that they are a target for the antiangiogenic effect of angiostatin.

Theological issues in genetics.

Theological reflection can contribute a distinctive perspective from which to analyze and evaluate moral debates about issues in modern genetics and reproductive medicine. The author appeals to two hermeneutical themes, human beings as "images of God" and the tendency of humans to "play God," in order to discuss various church statements and theological literature on human gene transfer, somatic cell nuclear transplant cloning of human beings, and patenting of human genes.
