K–12 Online Distance Education: Issues and Frameworks

With increasing popularity and accessibility of the Internet and Internet-based technologies, coupled with the need for a diverse group of students to have various means to complete their education, the prevalence of K-12 online and blended programs continues to increase

Intramural and subserosal echogenic foci on US in large-bowel intussusceptions: prognostic indicator for reducibility?

Background: In large-bowel intussusceptions, several US signs are known to indicate a lower likelihood of reducibility by enema. US can demonstrate echogenic dots or lines (foci) in the bowel wall, which might indicate an ischemic bowel. Objective: To determine the presence of echogenic intramural and subserosal foci in large-bowel intussusceptions and to evaluate the degree of correlation with reducibility. Materials and methods: Between 2001 and 2008, 74 consecutive US examinations were retrospectively evaluated by two pediatric radiologists for intramural and subserosal echogenic foci, or trapped gas, in the intussusception. The degree of correlation between the sonographic findings and reducibility was evaluated. Results: Of 73 intussusceptions examined by US, 56 (76%) were reducible and 17 (23%) were not reducible. Out of 10 intussusceptions with intramural gas, 11 with subserosal gas, and 14 with intramural and subserosal gas, 8 (80%), 6 (56%), 9 (64%), respectively, were not reducible. The presence of intramural gas or subserosal gas or both predicted a lower chance of reduction, but with regard to the effect of these findings together, intramural gas was the only significant predictor. Conclusion: Having intramural gas in large-bowel intussusception significantly decreases the chance of reductio

Defeating the Developer\u27s Dilemma: An Online Tool for Individual Consultations

This chapter introduces an online consultation tool that helps resolve the tension that developers often experience in consultations between offering quick fixes and providing in-depth but time-consuming conceptual understanding. The tool that the Eberly Center for Teaching Excellence has developed provides instructors with concrete teaching strategies to address common teaching problems, while also educating them about the pedagogical principles informing those strategies. The tool can be used to enhance traditional face-to-face consultations or, by itself, to reach a wider faculty audience, including adjunct and off site faculty

An elusive nasopharyngeal hamartoma in a neonate

A rare, elusive, mobile, pedunculated nasopharyngeal tumor in a neonate is described. The child was only intermittently symptomatic and the diagnosis was not made until 1 month of age.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/46687/1/247_2006_Article_BF02389013.pd

Testicular infarction in the newborn: Ultrasound findings

Three patients with neonatal testicular torsion and infarction (two bilateral, one unilateral) are presented with a distinctive sonographic appearance. All five testes appeared inhomogeneously hypoechoic and each was surrounded by a brightly echogenic rim. Whereas surgical exploration was required in the past to establish the diagnosis of testicular infarction in the neonate, sonographic demonstration of the abnormality in the appearance of the testicular parenchyma permits nonoperative diagnosis. Because surgical salvage of the testis in the setting of neonatal extravaginal torsion is thought to be quite rare, the necessity of removing the testis is less clear when the diagnosis is established preoperatively.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/46692/1/247_2005_Article_BF02013166.pd

Single sysem ectopic ureters and ureteroceles associated with dysplastic kidney

Eight children forming an uncommon subgroup of renal obstructive dysplasia are presented. Each child had a nonfunctioning dysplastic kidney with a single collecting system with ectopic ureteral insertion and/or ureterocele. Five of the children had classic multicystic dysplastic kidneys, one had they hdyronephrotic type of multicystic dysplasia kidney had two had hypoplastic kidneys. Other significant medical problems in 5 of the 8 children (63%Z) included VACTERL association, congenital heart diseaise and other genitourinary malformations. Unlike some children with unilateral multicystic dysplasia kidney, this subgroup of children ahs an increased risk of infection. The must be correctly identified on imaging so that tailored clinical management decisions can be made and associated anomalies detected.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/46698/1/247_2005_Article_BF02012501.pd
