Insights into informal practices of sport leadership in the middle east: the impact of positive and negative wasta
This study aims to explore and understand the impact of one of the informal culture forces on leadership corruption in sport settings. Semi-structured interviews were conducted with 18 individuals. Board members, presidents, and secretaries general were asked via phone interviews to describe the term wasta, using evidence from non-profit sectors in the Arab Middle East. The results show that when wasta is considered from a positive perspective, it is perceived as a means to solve problems or avoid bureaucracy, whereas it is perceived as corrupt behavior when it is considered from a negative perspective. Practical implications of the findings are discussed, together with limitations and ideas for future research
Safety of Epidural Corticosteroid Injections
BACKGROUND AND OBJECTIVE: Epidural corticosteroid injections (ESIs) have been used for several decades and now represent the most common intervention performed for the management of back pain with a radicular component. However, several reports have presented devastating complications and adverse effects, which fuelled concerns over the risk versus clinical effectiveness. The authors offer a comprehensive review of the available literature and analyse the data derived from studies and case reports. METHODS: Studies were identified by searching PubMed MEDLINE, Ovid MEDLINE, EMBASE, Scopus, Google Scholar and the Cochrane Library to retrieve all available relevant articles. Publications from the last 20 years (September 1994 to September 2014) were considered for further analysis. Studies selected were English-language original articles publishing results on complications related to the technique used for cervical and lumbar ESIs. The studies had to specify the approach used for injection. All studies that did not fulfil these eligibility criteria were excluded from further analysis. RESULTS: Overall, the available literature supports the view that serious complications following injections of corticosteroid suspensions into the cervical and lumbar epidural space are uncommon, but if they occur they can be devastating. CONCLUSIONS: The true incidence of such complications remains unclear. Direct vascular injury and/or administration of injectates intra-arterially represent a major concern and could account for the vast majority of the adverse events reported. Accurate placement of the needle, use of a non-particulate corticosteroid, live fluoroscopy, digital subtraction angiography, and familiarisation of the operator with contrast patterns on fluoroscopy should minimise these risks. The available literature has several limitations including incomplete documentation, unreported data and inherent bias. Large registries and well-structured observational studies are needed to determine the true incidence of adverse events and address the safety concerns
