Randomized Controlled Trial Multicenter Study Clinical Trial
Effect of triamcinolone acetonide injections on hemiplegic shoulder pain : A randomized clinical trial.
Background and Purpose-Hemiplegic shoulder pain is not uncommon after stroke. Its origin is still unknown, and although many different methods of treatment are applied, none have yet been proved to be effective. We sought to study the efficacy of 3 injections of intra-articular triamcinolone acetonide on pain and arm function in stroke patients with hemiplegic shoulder pain. ⋯ -In the 37 participants included in this study, triamcinolone injections seemed to decrease hemiplegic shoulder pain and to accelerate recovery, but this effect was not statistically significant. Therefore, on the basis of the results of this study, these injections cannot be recommended for the treatment of patients with hemiplegic shoulder pain.

Clinical Trial
Incident hemorrhage risk of brain arteriovenous malformations located in the arterial borderzones.
We sought to assess the relative risk of hemorrhagic presentation of brain arteriovenous malformations (AVMs) located in the arterial borderzone territories. ⋯ Our findings suggest that borderzone location is an independent determinant for a lower risk of AVM hemorrhage at initial presentation.

Clinical Trial Controlled Clinical Trial
Cerebral autoregulation in subjects adapted and not adapted to high altitude.
Impaired cerebral autoregulation (CA) from high-altitude hypoxia may cause high-altitude cerebral edema in newcomers to a higher altitude. Furthermore, it is assumed that high-altitude natives have preserved CA. However, cerebral autoregulation has not been studied at altitude. ⋯ All Sherpas and the majority of the newcomers showed impaired CA. It indicates that an intact autoregulatory response to changes in blood pressure is probably not a hallmark of the normal human cerebral vasculature at altitude and that impaired CA does not play a major role in the occurrence of cerebral edema in newcomers to the altitude.
