Case ReportsYawning despite trismus in a patient with locked-in syndrome caused by a thrombosed megadolichobasilar artery.
We report a 62-year-old woman with a locked-in syndrome with bilateral masticatory spasms and persistent trismus, who was still able to yawn. A vascular malformation of the basilar artery-megadolichobasilar artery (fusiform aneurysm, vertebrobasilar dolichoectasia) was determined to be the underlying cause of this rare combination of symptoms. A thrombus in the megadolichobasilaris as well as an almost total pontine infarction were demonstrated on CT- and MRI-scans. Thus, trismus may be associated with locked-in syndrome due to megadolichobasilar artery thrombus, although yawning is still possible.

Case ReportsDelayed manifestation of spinal metastasis: a special feature of hemangiopericytoma.
Metastatic hemangiopericytoma to the spine is rare, and operative management of these highly vascularized tumors is challenging. Review of the literature identified only seven previously reported cases. Metastases of hemangiopericytomas to the spine are diagnosed often only after a long delay following resection of the primary tumors. ⋯ One year later, however, new metastases were present. Patients with hemangiopericytoma should be controlled regularly for local recurrence and systemic tumor spread. The best available treatment for delayed metastasis to the spinal column is complete tumor removal followed by postoperative radiotherapy.

Clinical TrialIs mannitol safe for patients with intracerebral hemorrhages? Renal considerations.
Mannitol, a drug widely used to decrease intracranial pressure, can cause renal failure. The goal of this study is to determine the renal safety of mannitol therapy in patients with intraparenchymal hemorrhages. ⋯ Our study points out safety of mannitol therapy under control of osmolality, although control of urea and creatinine concentrations in special group of patients (persons with history of renal failure or diabetes) should be considered.

Case ReportsIntravenous immunoglobulin monotherapy in long-term treatment of myasthenia gravis.
To investigate effectiveness of long-term treatment of myasthenia gravis (MG) with intravenous immunoglobulin (IVIG). ⋯ IVIG therapy is a convenient, effective therapy when used selectively for treatment of MG on a long-term basis without any significant side effects.

Clinical TrialMild hypothermia therapy for patients with severe brain injury.
The authors present a group of patients with severe head injuries in which deliberate mild hypothermia was carried out together with the standard treatment protocol according to the European Brain Injury Consortium. Thirty patients with severe head injuries with Glasgow Coma Scale (GCS) score of 3-8 were enrolled into the study. The subjects were divided into two groups. ⋯ Mean normothermia CPP value of 72+/-3 mmHg significantly increased (P value 0.0007) during this time to 80+/-4 mmHg with unchanged systolic arterial pressure (P value 0.9013). There were no cardiac or coagulopathy-related complications. Our results showed that mild therapeutic hypothermia could be useful in improving the outcome and neurological recovery in patients with severe head injuries.
