Canine retraction and anchorage loss Self-ligating versus conventional brackets in a randomized split-mouth study.

Conclusions: Both brackets showed the same velocity of canine retraction and loss of anteroposterior anchorage of the molars. No changes were found between brackets regarding the inclination of canines and first molars. PMID: 24592906 [PubMed - as supplied by publisher]

Background: Inpatient stroke-codes (ISC) have traditionally seen low treatment rates with IV-thrombolytic (IVT). The purpose of this study was to identify the predictors of true stroke, prevalent IVT-treatment gap and study the factors associated with such missed treatment opportunities (MTO).Methods: A retrospective chart review identified ISC from March 2017 to March 2018. Clinical, radiographic and demographic data were collected. Primary analysis was performed between stroke vs. non-stroke diagnoses. Dichotomous variables were analyzed using Chi-Square test of proportions and continuous variables with Wilcoxon-Ranked-S...

In this study, we acquired computed tomography scans of three Standardbred trotting colts longitudinally between 2 and 12 months of age. Finite-element models were constructed of the left forelimb proximal phalanx and used to assess strain energy density during quiet standing. Growth related changes in mineral density and bone area fraction in the distal epiphysis, mid-diaphysis, and proximal epiphysis were evaluated. Mineral density and bone area fraction uniformly increased in the diaphysis and strain energy density was constant during growth, indicating adaptation to quiet standing. Bone mineral density and bone area fr...

Authors: Sibanda D, Singleton R, Clark J, Desnoyers C, Hodges E, Day G, Redding G Abstract Recent literature has highlighted the importance of transition from paediatric to adult care for children with chronic conditions. Non-cystic fibrosis bronchiectasis is an important cause of respiratory morbidity in low-income countries and in indigenous children from affluent countries; however, there is little information about adult outcomes of childhood bronchiectasis. We reviewed the clinical course of 31 Alaska Native adults 20-40 years of age from Alaska's Yukon Kuskokwim Delta with childhood bronchiectasis. In pa...

Conclusions: TBL can be an effective instructional approach to improve students' understanding of radiologic technology content. The results of this research can help instructors decide what action plan to implement to increase the effectiveness of TBL when further employing it for radiologic technology courses.

Authors: Conti MS, Ellis SJ Abstract Weight-bearing CT (WBCT) scans of the foot and ankle have improved the understanding of deformities that are not easily identified on radiographs and are increasingly being used by orthopaedic surgeons for diagnostic and preoperative planning purposes. In contrast to standard CT scans, WBCT scans better demonstrate the true orientation of the bones and joints during loading. They have been especially useful in investigating the alignment of complex pathologies such as adult-acquired flatfoot deformity in which patients have been found to have a more valgus subtalar joint alignme...

ConclusionThe reading on the ERC does not equate to the actual rod lengthening. The authors would recommend that clinicians using the MCGR for the treatment of early-onset scoliosis include pre- and post-extension imaging (radiographs or ultrasound) to confirm extension lengths at each outpatient extension. In centres with ultrasound facilities, we would suggest that patients should have ultrasound to monitor each lengthening after distraction but also 6-month radiographs.Graphic abstractThese slides can be retrieved under Electronic Supplementary Material.

This study found no difference between treatment in one visit or treatment over multiple visits (1/117 single ‐visit participants lost a tooth versus 2/103 multiple‐visit participants; odds ratio (OR) 0.44, 95% confidence interval (CI) 0.04 to 4.78; very low‐quality evidence). We found no evidence of a difference between single ‐visit and multiple‐visit treatment in terms of radiological failure (risk ratio (RR) 0.91, 95% CI 0.68 to 1.21; 1493 participants, 11 studies, I2 = 18%; low ‐quality evidence); immediate postoperative pain (dichotomous outcome) (RR 0.99, 95% CI 0.84 to 1.17; 1560 participants, 9 studies...
