Review Case ReportsSpontaneous pneumomediastinum and epidural pneumatosis in an adolescent precipitated by weight lifting: a case report and review.
Spontaneous pneumomediastinum is an uncommon condition in athletes. The most common cause of spontaneous pneumomediastinum is alveolar rupture into the bronchovascular sheath as a result of increased intrathoracic pressure. Epidural pneumatosis (pneumorrhachis) has been rarely associated with spontaneous pneumomediastinum. ⋯ To our knowledge, there have been only 5 case reports of pneumomediastinum precipitated by weight lifting. Improper breathing technique during weight lifting can increase the intrathoracic pressure and the risk of pneumomediastinum; hence, it is important that physicians and trainers who work with athletes provide instructions regarding proper breathing techniques during weight lifting. In addition to the case discussion, this article reviews spontaneous pneumomediastinum and epidural pneumatosis.

Randomized Controlled TrialExamining the degree of pain reduction using a multielement exercise model with a conventional training shoe versus an ultraflexible training shoe for treating plantar fasciitis.
Plantar fasciitis is a common injury to the plantar aponeurosis, manifesting as pain surrounding its proximal insertion at the medial calcaneal tubercle. Pain is typically worse in the morning when getting out of bed, and may subside after the tissue is sufficiently warmed up. For running-based athletes and individuals who spend prolonged periods of time on their feet at work, plantar fasciitis may become recalcitrant to conservative treatments such as ice, rest, and anti-inflammatory medication. ⋯ Twenty-one subjects completed the program (9 FREE; 12 CON). Both groups reported significant improvements in pain by the 6-month follow-up, and the FREE group reported an overall reduced level of pain throughout the study as a result of lower mean pain scores at the midpoint and post-test compared with the CON group. The exercise regimen employed in this study appears to reduce pain associated with chronic plantar fasciitis, and in doing so, the Nike 5.0 shoe may result in reductions in pain earlier than conventional running shoes.

ReviewExercise performance by hemodialysis patients: a review of the literature.
Hemodialysis (HD) patients exhibit poor functional capacity and reduced quality of life as a result of the complications associated with end-stage renal disease (ESRD). A review of the literature indicates that regular physical activity can reduce the complications associated with ESRD by inducing adaptations in the cardiovascular, nervous, and musculoskeletal systems. ⋯ Hemodialysis patients can safely participate in a variety of exercise programs with minimal adverse effects. Intradialytic exercise programs that can incorporate aerobic and resistance exercise promote exercise adherence and should be encouraged on dialysis units.

Comparative StudyComputerized neuropsychological profiles of South African versus US athletes: a basis for commentary on cross-cultural norming issues in the sports concussion arena.
Computerized programs are widely used as part of the overall medical management of concussion in order to monitor recovery and facilitate safe return-to-play decisions. Typically, neurocognitive profiles of concussed athletes are compared with baseline and/or normative data in the absence of baseline scores. However, the cultural equivalence of performance on neuropsychological tests cannot be assumed and has not been sufficiently researched. ⋯ It was concluded that US neurocognitive normative data on the ImPACT test are appropriate for use on South African athletes whose first language is English, whereas culture-specific sensitivity for symptom reporting on this same population should be taken into consideration for management purposes. It is argued that neurocognitive equivalence is less likely to apply in educationally disadvantaged populations. The use of registered psychologists is deemed necessary to provide contextualized interpretations of computerized test scores, thereby protecting against misdiagnosis that may occur within the concussion management arena via actuarial approaches that fail to take sociocultural complexities into account.
