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.

Cardiogenic shock has long been a difficult problem for clinicians. The most common cause is left ventricular pump failure after myocardial infarction, but other important causes include mechanical complications of infarction, right ventricular dysfunction, prolonged cardiopulmonary bypass, valvular disease, and cardiomyopathy. Cardiogenic shock is the leading cause of in-hospital death after myocardial infarction. ⋯ Improved understanding of the pathophysiology of cardiogenic shock has led to renewed emphasis on the notion that stunned or hibernating myocardium may recover function with hemodynamic support and restoration of flow. This concept has underscored the importance of expeditious initiation of supportive measures to maintain blood pressure and cardiac output, including both medications and intraaortic balloon counterpulsation. Finally, the theory that coronary revascularization would be beneficial by reversing the vicious cycle in which ischemia causes myocardial dysfunction, which in turn worsens ischemia, which had been supported by an extensive body of observational and registry studies, has now been strongly buttressed by the results of two randomized, controlled trials, both of which show improved mortality with early revascularization for cardiogenic shock in the setting of acute infarction.

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.

Corticosteroid therapy in patients with severe sepsis and septic shock.
Corticosteroids have been considered for decades for the treatment of severe sepsis and septic shock, based on their pivotal role in the stress response and their hemodynamic and antiinflammatory effects. Whereas short-term therapy with high doses of corticosteroids (up to 42 g hydrocortisone equivalent for 1-2 days) has been ineffective or potentially harmful, prolonged therapy with lower doses (200-300 mg hydrocortisone for 5-7 days or longer) in septic shock has recently revealed beneficial effects in several randomized, controlled trials. Assuming relative adrenal insufficiency (RAI) and peripheral cortisol resistance, treatment with low-dose hydrocortisone improved shock reversal, reduced inflammation, and improved outcome. ⋯ In addition the role of fludrocortisone is uncertain. Nevertheless, based on current data, low-dose hydrocortisone therapy should definitely be considered in vasopressor-dependent septic shock. This review will address some critical points.

[Pharmacological treatment of trigeminal neuralgia: systematic review and metanalysis.].
Trigeminal neuralgia is a syndrome of chronic pain, characterized by paroxysms of excruciating pain which dramatically affect patients' quality of life. Systemic drug therapy is the first line treatment for this disease. This study aimed at evaluating efficacy, safety and tolerability of several pharmacologic treatments offered to trigeminal neuralgia patients, trying to supply evidences for clinical practice recommendations and to identify the needs for further research. ⋯ Carbamazepine is still the drug of choice for treating trigeminal neuralgia, being lamotrigine and pimozide indicated for cases refractory to conventional therapy. In addition, further studies are needed to determine future therapeutic options.
