Caudal epidural steroid injections are used for the symptomatic treatment of radicular lumbosacral pain syndromes, but incorrect injection placement has been recognized as a common problem with the routinely used unguided technique. We aimed to explore the use of sonography to facilitate this procedure. ⋯ Real-time sonography can facilitate caudal epidural steroid injections.

Randomized Controlled Trial Comparative Study Clinical Trial
Treated needles: do they facilitate sonographically guided biopsies?
We sought to compare needle visualization and diagnostic yield rates resulting from the use of several commercially available treated needles in sonographically guided biopsies. ⋯ The echogenic polymer-coated needle was the best visualized of all needles evaluated, both treated and untreated. No significant difference was found in diagnostic yield rates, but that may be reflective of the relatively small sample size.

Cerebral herniation resulting from postischemic brain edema is the most common cause of death in patients with large cerebral infarctions. Early monitoring of intracranial pressure and application of necessary treatment procedures may have life-saving value. In this study, the data obtained by transcranial Doppler sonography were compared with clinical examination and the neuroradiologic findings. ⋯ Transcranial Doppler sonography enables noninvasive monitoring of raised intracranial pressure in patients with large infarctions. It also provides information for detecting cerebral herniation and deciding on the medical or surgical therapy.
