Why are we here at the clinic? Parent–child (dis)agreement on referral problems at outpatient treatment entry.

Do clinic-referred children and their parents agree on the problems for which treatment is undertaken? The authors asked 381 outpatient-clinic-referred children and their parents to list, independently, the child's target problems. Of the parent-child pairs, 63 % failed to agree on even a single problem. When problems were grouped into broad categories (e.g., delinquent, withdrawn), more than a third of the pairs still failed to agree on a single broad problem area. Parent-child agreement was higher for externalizing than for internalizing problem categories (though poor for both). Low parent-child agreement may help explain the poor outcomes often reported for clinic-based child therapy. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Complications of cardiac hydatid cyst. 2 cases

BACKGROUND: Cardiac localization of hydatiosis is uncommon, involving 0.5 to 2% of all cases. CASE REPORTS: The first patient was a 15 year old adolescent whose cardiac hydatidosis was revealed by tamponade. The second case was discovered in a 28-year-old woman without cardiac signs who was explored for allergy manifestations with fever, urticaria and joint point. Both patients underwent surgery. Eighteen months after the operation, the second patient developed hemiplegia leading to the discovery of multi-organ localizations (brain, spleen, kidney) which were not evidenced at the initial work-up. The neurological deficit and brain cysts regress with albendazole treatment. DISCUSSION: The risk of rupture of the cardiac hydatic cyst requires rapid surgical cure. Medical treatments are discussed. Anti-hydatic drugs can be used alone in case of a contraindication for surgery. In other patients they are given during the perioperatie period and for a prolonged period after surgery.     

Inhibitory control over no-longer-relevant information: adult age differences

Hartmann and Hasher (1991) used a garden-path task in which younger and older adults generated the final word for each of a series of high-cloze sentences. Under instructions to remember the final word, the experiment included critical sentences for which the generated word was replaced by a new, to-be-remembered target. Using an implicit priming task, the first experiment replicated a basic finding: Younger adults showed priming only for the target words, whereas older adults showed priming for both the generated and target words. Two experiments explored the boundary conditions. One showed that an additional sentence that interpreted the new target word enabled older adults to narrow access to only the target word. The provision of additional time following the introduction of the new target word did not. Specific information, not more time, is required for inefficient inhibitory mechanisms to clear the recent past from memory.     

Should laparoscopic appendectomy be avoided for complicated appendicitis in children?

BACKGROUND/PURPOSE: Laparoscopic appendectomy is becoming the preferred technique for treating acute appendicitis. However, recent literature on adults suggests that laparoscopic appendectomy may increase the risk for postoperative infectious complications in complicated (gangrenous or perforated) cases. This study was undertaken to compare the results of open versus laparoscopic appendectomy for complicated appendicitis in children. METHODS: A retrospective review from two institutions was performed for all children treated operatively for complicated appendicitis from January 1994 through November 1996. RESULTS: Fifty-six cases were identified. Twenty-seven children underwent laparoscopic appendectomy, whereas 22 underwent open appendectomy. Seven children underwent conversion from laparoscopic to open surgery. Operating times and length of hospital stay did not differ significantly between the laparoscopic and open groups. Postoperative complications developed in 24 children (42.8%). Complications were more frequent after laparoscopic appendectomy compared with open appendectomy (56% v 18%, P = .002). A postoperative intraabdominal abscess (IAA) developed in 14 children (25%). An IAA occurred in two children after open appendectomy compared with 11 children after laparoscopic appendectomy (9% v 41%, P = .01). CONCLUSION: The findings suggest that laparoscopic appendectomy should be avoided in children who have complicated appendicitis because of the increased risk for postoperative intraabdominal abscesses. The authors propose a prospective, randomized trial to verify this finding.     

Perceptions of counselor source characteristics by premature and successful terminators.

Examined 56 premature and 148 successful terminators' perceptions of counselor source characteristics and satisfaction with counseling services at a university counseling center. S-completed measures included the Client Satisfaction Questionnaire and a counselor rating form. Results indicate that Ss who terminated prematurely were less satisfied with counseling services that they received and viewed their counselors as less expert, attractive, and trustworthy than did Ss who terminated successfully. Ss who responded anonymously to the evaluation form viewed the counselors as less attractive and trustworthy and also expressed less satisfaction with counseling than did those who did not respond anonymously. Significant though modest correlations between ratings of source characteristics and client satisfaction were also found. (16 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Holographic matched filter for full-field in-line signal processingof optical-fiber sensor outputs

A holographic matched filter is used to measure the changes in the output of a dual-mode fiber undergoing axial strain. The hologram is formed by interfering collimated light from a single-mode reference fiber and an unstrained dual-mode sensor fiber on a small piece of holographic material. When the hologram is illuminated by the strained sensor fiber, the cross-correlation field comparing the dual-mode output and its previous state, as recorded in the hologram, is collected, focused into a pick-up fiber, and sent to a photodiode. This arrangement allows for a compact, in-line method for full-field processing of the strain-induced changes in phase and amplitude in the sensor fiber. Other uses of such fiber-based correlators are suggested

Methods for Biomimetic Remineralization of Human Dentine: A Systematic Review

This study aimed to review the laboratory methods on biomimetic remineralization of demineralized human dentine. A systematic search of the publications in the PubMed, TRIP, and Web of Science databases was performed. Titles and abstracts of initially identified publications were screened. Clinical trials, reviews, non-English articles, resin-dentine interface studies, hybrid layer studies, hybrid scaffolds studies, and irrelevant studies were excluded. The remaining papers were retrieved with full texts. Manual screening was conducted on the bibliographies of remaining papers to identify relevant articles. A total of 716 studies were found, and 690 were excluded after initial screening. Two articles were identified from the bibliographies of the remaining papers. After retrieving the full text, 23 were included in this systematic review. Sixteen studies used analogues to mimic the functions of non-collagenous proteins in biomineralization of dentine, and four studies used bioactive materials to induce apatite formation on demineralized dentine surface. One study used zinc as a bioactive element, one study used polydopamine, and another study constructed an agarose hydrogel system for biomimetic mineralization of dentine. Many studies reported success in biomimetic mineralization of dentine, including the use of non-collagenous protein analogues, bioactive materials, or elements and agarose hydrogel system.     

Energy based method for numerical fatigue analysis of multidirectional carbon fibre reinforced plastics

Abstract

This paper describes experiments on multiaxial fibre reinforced plastic laminates, which were performed to obtain calibration data for numerical fatigue analyses. For this purpose, fatigue tests of laminates with multidirectional layers subjected to constant amplitude and block loading (0?≤?R?<?1 or R>1) were analysed. The presented simulation results display the fatigue behaviour of carbon fibre reinforced plastics for unidirectional loading conditions and a selected laminate.
