Sex Differences in the Chronology of Deciduous Tooth Emergence in White and Black Children

Tooth emergence in 376 black and white children between the ages of 4 and 33 months was studied in southeastern Michigan. The results indicate a trend in both groups for boys to show earlier tooth emergence in early stages and for girls to show earlier tooth emergence in later stages of deciduous tooth emergence.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/66947/2/10.1177_00220345740530024001.pd

Evaluating Retinal Function in Age-Related Maculopathy with the ERG Photostress Test

PURPOSE. To evaluate the diagnostic potential of the electroretinogram (ERG) photostress test and the focal cone ERG in age-related maculopathy (ARM). METHODS. The cohort comprised 31 patients with ARM and 27 age-matched control subjects. The ERG photostress test was used to monitor cone adaptation after intense light adaptation. Focal 41- and 5-Hz cone ERGs were recorded monocularly (central 20°) to assess steady state retinal function. Univariate analysis identified electrophysiological parameters that differed between groups, and receiver operating characteristic (ROC) curves were constructed to assess their diagnostic potential. Logistic regression analysis determined the diagnostic potential of a model incorporating several independent predictors of ARM. RESULTS. The rate of recovery of the ERG photostress test was reduced (recovery was slower) in subjects with ARM. The parameter exhibited good diagnostic potential (P = 0.002, area under ROC curve = 0.74). The implicit times of the 5-Hz (a-wave, P = 0.002; b-wave, P < 0.001) and the 41-Hz (P < 0.001) focal cone ERGs were increased, and the 41-Hz focal cone ERG amplitude (P = 0.003) and focal to full-field amplitude ratio (P = 0.001) were reduced in the ARM group. Logistic regression analysis identified three independent predictors of ARM, including the rate of recovery of the ERG photostress test. CONCLUSIONS. Early ARM has a marked effect on the kinetics of cone adaptation. The clinical application of the ERG photostress test increases the sensitivity and specificity of a model for the diagnosis of ARM. Improved assessment of the functional integrity of the central retina will facilitate early diagnosis and evaluation of therapeutic interventions

Childhood retardation resulting in reduction of adult body size due to lesser adolescent skeletal delay

The skeletal maturation of 7972 rural children from the six Central American nations, aged one month through 22 years, is evaluated. The results suggest that retardation in skeletal maturation during childhood is significantly greater than during adolescence, while growth in body size shows a progressive delay from infancy through adolescence. In other words, the apparent improvement in skeletal maturation during adolescence is not associated with an equivalent “catch-up” in body size. Similarly, prolongation of the period of growth does not fully compensate for the slow rate of growth. It is postulated that the small stature in Central America is related to the marked childhood retardation and to the fact that during adolescence, the timing of skeletal maturation is less affected than growth in size.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/37507/1/1330330306_ftp.pd

Tribology of Medical Devices

Importance of tribology in a number of medical devices and surgical instruments is reviewed, including artificial joints, artificial teeth, dental implants and orthodontic appliances, cardiovascular devices, contact lenses, artificial limbs and surgical instruments. The current focus and future developments of these medical devices are highlighted from a tribological point of view, together with the underlying mechanisms

Three Approaches to Cooperative Learning in Higher Education

This paper first discusses cooperative learning and provides a rationale for its use in higher education. From the literature, six elements are identified that are considered essential to the success of cooperative learning: positive interdependence, face-to-face verbal interaction, individual accountability, social skills, group processing, and appropriate grouping. Three distinct approaches at the postsecondary level are described in the fields of Medicine, Dentistry and Mathematics, and feedback from faculty and students is reported. The three approaches are presented within the context of the disciplines and are compared across the disciplines with respect to the essential six elements. Finally, the authors share some lessons learned from their research and experience in order to assist faculty who wish to incorporate cooperative learning into their teaching.Les auteurs de cet article examinent le concept d'apprentissage coopératif et proposent une justification de son application au niveau de l'enseignement supérieur. Les éléments considérés, essentiels à la réussite de l'apprentissage coopératif, proviennent d'articles et d'ouvrages précédemment publiés. Ils sont les suivants: interdépendance positive, intéraction sous forme de face â face verbal, notion de responsabilité individuelle, souabilité, discussions sur le fonctionnement du groupe et regroupements appropriés. Trois approches spécifiques aux domaines de la médecine, la médecine dentaire et des mathématiques y sont décrites ainsi que les observations des professeurs et des étudiants. Les trois approches sont comparées selon les six critères de réussite, déterminés auparavant pour montrer que la nature structurée de l'apprentissage coopératif offre néanmoins un grand champ de manoeuvre. En conclusion, les auteurs de l'article expliquent quelles leçons ils ont tirées de leur recherche et de leur expérience, afin d'aider les professeurs désireux d'introduire l'apprentissage coopératif dans leur enseignement
