[Scurvy, a re-emerging disease].

BACKGROUND: Scurvy is the clinical manifestation of vitamin C deficiency. It is historically linked to the era of great maritime expeditions. But it is remerging in Western countries as in France. SITUATION: Nowadays, scurvy mainly affects homeless populations of large occidental cities and the isolated and malnourished inhabitants of developing countries. The clinical presentations of scurvy are numerous and often misleading and its evolution without treatment is always lethal. After years of wanderings and research, the physiopathological mechanisms of scurvy were finally understood, due to the will of outstanding personalities who took the risk to brave the established superstitions in order to apply a strict medical approach. PERSPECTIVES: Scurvy must still be prevented in at risk-populations. Indeed a pocket meal enriched with vitamin C is distributed to homeless people in Paris.

[The formation of neurons in the bone marrow, the dream of alchemy in the new millenium].

In rodents, bone marrow contains stem cells that have the potentiality to differentiate into mesodermal and non-mesodermal cells, both in vitro and in vivo. These cells can populate a wide panel of organs such as the liver, the brain, the lungs, the heart.... They appropriately differentiate according to the environment in which they migrate and are known to assume specific functions. Even in adult animals, these cells can migrate and differentiate. Such a potentiality suggests exciting therapeutic outcomes. Brain lesions could benefit of such techniques. These experimental protocols should be precisely controlled before their use in medicine in order to solve problems that still remain such as the permeability of the hemato-encephalic barrier, the integration of differentiated grafted cells into local functional neural networks.

A comparison of etodolac (Ultradol) with acetaminophen plus codeine (Tylenol #3) in controlling post-surgical pain in vasectomy patients.

The efficacy and safety of etodolac (Ultradol) and acetaminophen plus codeine [A + C (Tylenol #3)] in controlling post-surgical pain were compared in an open-label, randomized, parallel-group outpatient study. Patients who were voluntarily having a vasectomy performed for sterilization were assigned to receive either etodolac 200 mg (20 patients) or A + C (20 patients). All medication was taken as required for up to 7 days. Efficacy assessments were made at 1, 6 and 24 hours after surgery and included pain measurement (Likert Visual Analogue scale), patient and physician global assessments and time to analgesic relief. Safety assessments were made throughout the study and included vital signs and adverse event monitoring. Results of the study indicated that patients taking etodolac were more likely to say they could return to work 24 hours after their vasectomy (p = 0.04). There were no other statistically significant differences between the two groups of patients. The results from this study indicate that etodolac and A + C are equally efficacious and well-tolerated for the control of post-vasectomy pain and that patients may observe an increased benefit with etodolac by being able to return to work sooner.
