Review Comparative Study
Dangers of growth hormone therapy in critically ill patients.
Prolonged stay of patients is the major challenge for modern intensive care because of its effects on morbidity and resource utilization. Severe trauma or infection are associated with the catabolic response, characterized by increased protein turnover and negative nitrogen balance. Severe catabolism leads to end-organ dysfunction and muscular weakness prolonging the need for mechanical ventilation. ⋯ In contrast to the results of these relatively small studies, a recent multinational randomized controlled trial revealed that the administration of rhGH (with doses 10-20 times higher than those used for replacement therapy) increases the mortality of critically ill patients. This excessive mortality in patients treated with rhGH was related to infections and development of multiple organ failure. Administration of high doses of rhGH to critically ill patients cannot thus be recommended.

Review Comparative Study
Evidence-based data on pain relief with antidepressants.
This structured review addresses the issue of whether antidepressants have an antinociceptive (analgesic) effect for chronic pain independent of their antidepressant effect. In order to answer this question, human acute pain studies, individual placebo-controlled studies for the treatment of specific chronic pain syndromes, and metaanalytic studies were reviewed and placed into table format. Analysis of this evidence led to the following conclusions: The evidence was consistent in indicating that overall antidepressants may have an antinociceptive effect in chronic pain, and that these drugs were effective for neuropathic pain. ⋯ This evidence also strongly suggested that serotonergic-noradrenergic antidepressants may have a more consistent antinociceptive effect than the serotonergic antidepressants. Finally, this evidence indicated that antidepressants could be effective for pain associated with some specific pain syndromes, such as chronic low back pain, osteoarthritis or rheumatoid arthritis, fibrositis or fibromyalgia, and ulcer healing. Possible reasons for the conflicting results of studies in this area are presented, and problems that could limit the validity of the conclusions of this review are discussed.
