To evaluate the effects of reoperation with deep brain stimulation (DBS) in the caudal zona incerta (cZi) in patients with failed DBS in the ventral intermediate (Vim) nucleus of the thalamus for essential tremor. ⋯ The effect on tremor was, in this small sample population, improved by implanting an electrode in the cZi. The effect was modest in those patients suffering a deterioration years after the initial operation.

To determine whether perfusion computed tomography (CT) is useful for identifying patients with poor-grade subarachnoid hemorrhage (SAH) with reversible etiologies and whether early obliteration in patients with poor-grade aneurysmal SAH leads to favorable outcomes. ⋯ Early bilateral prolonged MTT at the thalami and old age are associated with a poor outcome. Early obliteration benefits a significant portion of SAH patients.

To depict the clinical, operative, and histological features of Rathke cleft cysts (RCCs) in consideration of therapeutic results and recurrence rates. ⋯ When RCCs are recognized intraoperatively, the evacuation of their contents and partial cyst obliteration generally afford dramatic improvements in a patient's clinical signs and symptoms, along with low complications and rate of recurrence.
