Comparative Study
[Pain prevention with fixed 50% nitrous oxide-oxygen mixture during bone-marrow biopsy].
During bone-marrow biopsy, one third of patients score their pain as moderate or severe. Combination of analgesic and hypnotic is effective at reducing pain, but prolonged medical surveillance is necessary. The objective of the study was to assess the effectiveness and ease of use of the equimolar nitrous oxide-oxygen mixture (nitrous oxide), a short acting analgesic with little sedative effect, during bone-marrow biopsy. ⋯ Nitrous oxide is an effective analgesic when performing bone-marrow biopsies. Ten percent of patients feel a moderate to severe pain instead of one third. Despite some mild side effects, there is a very good appreciation by patients. Since this study, the authors routinely use nitrous oxide.

Case Reports
[Microscopic colitis associated with celiac disease probably triggered by the administration of venlafaxine].
The association of microscopic colitis with celiac disease is rare. A case of microscopic colitis associated with celiac disease and following administration of venlafaxine in a 67-year-old patient is described. The pathophysiologic hypotheses of such an association are discussed.

Meta Analysis Comparative Study
[Effects of corticosteroids on adults with tuberculous meningitis admitted to intensive care unit: a propensity score analysis].
The beneficial effect of corticosteroids has been well established, particularly in patients free of infection with the human immunodeficiency virus. In intensive care units, the high risks of infection to which patients are exposed specifically could offset the neurological benefit of corticosteroids. The purpose of the study was to assess the effects of corticosteroids in adult patients with tuberculous meningitis admitted to intensive care unit. ⋯ This study found no significant improvement in survival in adult patients with tuberculous meningitis admitted to intensive care who received dexamethasone. However, the confidence interval was in accordance with the 0.78 relative risk estimated by the meta-analysis Cochrane version 2008. There was no significant difference for nosocomial infections between the group Corticosteroids and the group No corticosteroids. A probable lack of statistical power may explain these results.
