In a statement from the Section on Diseases of the Chest of the American Academy of Pediatrics entitled "The Tuberculin Test,"1 the second paragraph of a comprehensive article begins as follows: "A routine tuberculin test should be performed sometime during the first year of life and annually or biennially thereafter." This recommendation for the frequency of routine tuberculin testing differs from that currently proposed by others. The same issue of Pediatrics contains an article by Dr. Phyllis Q. Edwards entitled "Tuberculin Testing of Children."2 The Summary of the article states "The pediatrician should review and analyze tuberculin test results based on his personal experience.

AbstractThis study is based on 145 pairs of twins included in a longitudinal study of a cohort of singletons born in 1953 and living in the Stockholm metropolitan area in 1963. Of these 145 pairs, 28 were classified as MZ, 103 as DZ and 14 pairs could not be classified. School achievement and ability test results have been collected for this group as well as data for the boys from physical and mental examinations on enrollment to military service. The purpose of this study was to compare within-pair similarity for MZ and DZ twins from birth onwards. There seems to be a divergent trend over time for MZ twin pairs to become more similar and DZ twin pairs to become less similar in height growth, school achievement and verbal ability. This is in accordance with previous research in this field. In relating similarity within pairs to birthweight, we found a drop in within-pair similarity for low birthweight MZ and DZ twin pairs (both twins ≤2.500 g), but not for normal weight twin pairs. A discussion is initiated concerning methodological implications of these results.

Many states provide incentives to students, teachers, and schools for the participation and success of students on Advanced Placement (AP) examinations administered by the College Board. The purpose of this article is to examine whether these incentives help students enroll and succeed in AP exams. An analysis of nationally representative AP exam data, taken from the Education Longitudinal Study of 2002, revealed that AP exam fee exemption, the most prevalent incentives, leads to an increase in the likelihood of AP course enrollees taking the exam—in particular, the disadvantaged. In contrast, little evidence was found that performance-based incentives, to which several states link AP test results, are helpful for improving AP exam participation and performance.

Background/Aim. Balanced occlusal arrangement of artificial teeth and balanced occlusion is a specific type of occlusion that preserves the stability of complete dentures. Balanced occlusion comprises realization of tooth contacts at the working side as well as at the balancing side, at the same time. The aim of this study was to assess the influence of balanced occlusal arrangement of artificial teeth on the decrease in reduction of edentulous alveolar ridge. Methods. A longitudinal study on 91 fully edentulous patients was conducted using their panoramic radiographs and parameters of vertical dimension of edentulous ridges. All the patients were clinically examined by the same and a qualified dental practitioner. Numerical values of parameters of vertical dimensions of edentulous ridges and lines were statistically processed and compared using the Student?s t-test. Results. Vertical dimensions and heights of edentulous ridges were different after comparison of parameters in complete denture wearers with balanced occlusion and complete denture wearers without bilaterally balanced occlusion, as well as between male and female edentulous patients. Statistically significant differences of heights were established in complete denture wearers? with a set of artificial teeth without balanced occlusion, at the baseline and 12 months after wearing of complete dentures. Conclusion. Balanced occlusion is a favored occlusal design in setting of artificial teeth in conventional complete dentures, which preserves edentulous ridge and influence the stability of dentures.

A cortisol metabolite, 11-ketoetiocholanolone (11-k), is widely used in monitoring stress in several vertebrates, and can be detected by immunoassay. However, these assays have certain limitations with respect to specificity. Also, differences in the excretion of faecal glucocorticoid metabolites (FGM) among species and even between sexes make validation necessary in each case. Therefore, our aims were, first, to develop and validate a high-pressure liquid chromatography–tandem mass spectrometry (HPLC–MS/MS) methodology for monitoring 11-k in faeces of Iberian red deer (Cervus elaphus hispanicus), and second, to investigate the capability of our method to determine variations of this FGM in a longitudinal study. Third, and finally, we assessed the correspondence between faecal 11-k concentrations and plasma cortisol. An adrenocorticotropic hormone (ACTH) test was performed on six red deer stags translocated and kept in captivity for a week and faecal samples were collected twice a day. One single blood and faecal sample from another seven stags was also collected after 2 weeks in captivity. The results of the longitudinal study showed a first peak in 11-k 36 h after the ACTH test and handling, and a second peak at 120 h of being kept indoors. Maximum concentrations of 11-k ranged from 22.71 to 375.68 ng/g. In the second stag group, 11-k concentrations of 25.09 ± 20.53 ng/g had a correlation of r2 = 0.88 with the concentration of plasma cortisol, which was 54.6 ± 55.1 ng/mL. This technique is capable of detecting changes in the concentrations of faecal 11-k. The values determined have a good correlation with the cortisol concentration in blood, and we also detected differences in different individuals’ responses to the same stressors.

Tuberculin Tests

The pediatrician should review and analyze tuberculin test results based on his personal experience. This analysis coupled with knowledge of the tuberculosis situation in the community from which he draws his patients will suggest the degree to which he continues to perform tuberculin tests as a routine procedure. In effect, personal judgment of the pediatrician must determine on an individual basis whether tuberculin testing is necessary.

AbstractIn this report it is presented the results of a longitudinal pre-experimental study, it was realized a technological intervention to stimulate the phonological awareness through a tangible reading toy based on the RFID technology, consisting of a teddy bear and 30 letters in 3D from the Spanish alphabet. This study started with a sample of 200 children, from them, there were selected 17 children aged between 6 and 7 years (Mage = 6.47, SD = .51) with a phonological disorder from an educative institution. The procedure consisted of obtaining pre-test and post-test values with the Evaluation of Phonological Awareness (PECFO). Sampling inclusion criteria considered children presenting problems of phonemes’ recognition and its relationship with graphemes. During 30 weeks it was realized an intervention with the technological toy and at the end of the sessions, it was applied the post-test. Results of phonological awareness showed statically significant differences among the pre (M = 12.88, SD = 3.53) and post-test (M = 17.17, SD = 2.96) this contributes to the empirical evidence of the intervened group improvement in this cognitive function t(16) = −3.67, p = .002. From this research it is projected proposing technological innovations contributing in the treatment of children’s cognitive difficulties.
