OBJECTIVE To determine whether low bone density and other risk factors for osteoporosis are associated with stress fractures in athletes. DESIGN Case-control study. SETTING Institutional sports injury clinic with primary and secondary care. PARTICIPANTS Twenty-five athletes (nineteen women) with scintigraphically confirmed stress fractures matched for(More)
Bone mineral density (BMD) of the lumbar spine was measured in 97 long-term survivors of childhood cancer 5-23 years after diagnosis using dual-energy X-ray absorptiometry (DXA). They had been treated for acute leukemia (n = 22), brain tumors (n = 16), lymphomas (n = 16), Wilms' tumor (n = 10), neuroblastoma (n = 7) and other cancers (n = 26). The(More)
Osteopenia is common in preterm babies, but its pathogenesis is uncertain. In this study bone density in babies was quantitated, postnatal bone mineralization compared to expected intrauterine bone mineralization and the pathogenesis of osteopenia investigated. Healthy babies (103 term, 76 preterm) were examined clinically, biochemically and radiologically(More)
A popular approach to introducing students to computer science is to involve middle-school students in engaging programming activities. One challenge in such a program is attracting students who are not already positively predisposed to computing. In order to attract a diverse audience, we developed a summer program based on culturally-relevant themes that(More)
The nature and pathophysiology of the bone loss which occurs in term and especially preterm neonates are poorly understood, and it is unclear whether this neonatal osteopenia results from impaired bone formation or increased bone resorption. This study compared the static bone histomorphometry of preterm and term babies, employing iliac crest bone biopsy(More)
Serum levels of six acute phase proteins (APP)--C-reactive protein (CRP), serum amyloid A (SAA), alpha 1-antitrypsin, haptoglobin and complement fractions C3 and C4--were serially studied in 24 patients with poorly controlled diabetes mellitus, ten of whom had unequivocal evidence of an underlying infection. In diabetic patients without infection, no change(More)
We encountered two family members with a previously undescribed pure ectodermal dysplasia. The propositus exhibited hypotrichosis, hypodontia, focal linear dermal hypoplasia on the tip of her nose, irregular hyperpigmentation on her back, bilateral amastia and athelia, and mild nerve hearing loss. Her mother displayed similar characteristics, except for(More)
This study aims to evaluate surgical approaches to the management of retrosternal goitre. Between 2004 and 2014, 35 patients (eight males; mean age 67.4 ± 10.9 years) with retrosternal goitre (mainly right-sided in 9, left-sided in 14 and bilateral in 12) underwent surgery. A palpable neck mass was found in 11 (31.4%), stridor in 10 (28.6%) and(More)
Professional training programs strive to prepare students for success in their respective fields. Despite sustained and concentrated efforts, however, a serious gap exists between training and practice, particularly in fields requiring complex decision-making. In the field of education, the process of referring and assessing students for special education(More)
