Intradiscal electrothermal annuloplasty (IDET) is an effective treatment for chronic discogenic low back pain (LBP). However, efficacy of IDET for the treatment of referred leg pain has not been examined. This study was performed to assess the long-term efficacy of IDET for the treatment of referred leg pain in chronic discogenic LBP patients. ⋯ A relatively large number of LBP patients who underwent IDET (84%) presented with referred leg pain without sciatica. The IDET procedure afforded improvements in leg pain that correlated well with improvements in back pain (0.75/4 and 0.88/4, respectively). These data suggest that IDET may relieve associated limb pain in chronic discogenic LBP patients.

Survival from acute coronary syndromes and major trauma has been shown to depend on timely access to definitive treatment. We sought to identify the significance of intensive care unit (ICU) admission delay (lead-time) on the outcome of critically-ill medical patients with other diagnoses. ⋯ ICU admission delay (lead-time) is associated with a greater mortality-risk in critically ill medical patients requiring MV and/or RRT.

Simulators can be used to teach simple technical skills or used in more realistic settings to teach or assess various cognitive/affective skills. Although simulators have become widespread, their use and efficacy in these various areas have not been delineated and are still being explored. This review will discuss the present state of using medical simulation for airway-management training. ⋯ Simulators are here to stay. Presently their usage in teaching psychomotor skills has scientific validity in specific tasks but their efficacy for teaching higher-order cognitive skills is still evolving. Future studies will continue to delineate the usage in different areas by studying the outcome in skills training and retention.

In aortic arch surgery is there any benefit in using antegrade cerebral perfusion or retrograde cerebral perfusion as an adjunct to hypothermic circulatory arrest?
A best evidence topic in cardiothoracic surgery was written according to a structured protocol. The question addressed was whether patients having aortic arch surgery benefit from antegrade or retrograde cerebral perfusion in addition to hypothermic circulatory arrest to reduce neurological injury or mortality. ⋯ The author, journal, date and country of publication, patient group studied, study type, relevant outcomes, results, and study weaknesses of these papers are tabulated. We conclude that antegrade cerebral perfusion is superior as an adjunct to hypothermic circulatory arrest when compared to retrograde cerebral perfusion or hypothermic circulatory arrest alone, although clinical evidence for this from prospective clinical trials is weak.

Anemia is common in acute critically ill patients. Although blood loss, either by trauma, surgery, phlebotomies or gastrointestinal bleeding, may play a role, the anemia in these patients bears many similarities to the anemia characteristic of chronic disease. Serum iron is low with a high concentration of ferritin and low-to-normal transferrin and serum transferrin receptor levels. ⋯ In individual situations, such as in cardiovascular and cancer patients, higher thresholds may be appropriate. The administration of rh-EPO is an alternative to reduce the need for red blood cell transfusions and to avoid transfusion-related complications. Although its efficacy has been shown, questions regarding cost-benefit, dose regimen and clinical outcomes need to be answered before its large-scale use can be recommended.
