Randomized Controlled Trial
Rapid blood pressure reduction in acute intracerebral hemorrhage: feasibility and safety.
The optimal blood pressure (BP) for treating acute intracerebral hemorrhage remains (ICH) uncertain. High BP may contribute to hematoma growth while excessive BP reduction might precipitate peri-hemorrhage ischemia. We examine here the feasibility and safety of reducing BP to lower than presently recommended levels in patients with acute ICH. ⋯ A more aggressive reduction of acute hypertension after ICH does not increase the rate of neurological deterioration even when treatment is initiated within hours of symptom onset. Lowering BP aggressively did not affect hematoma and edema expansion but this possibility deserves further study.

No proven treatments exist for intracerebral hemorrhage (ICH). Carefully selected patients may benefit from surgery, and an international multicenter trial is ongoing. We sought to determine how many patients in a population-based ICH cohort would have been eligible for surgery using the Surgical Trial in Intracerebral Hemorrhage II (STICH II) criteria. ⋯ In this population-based ICH cohort, 7.7% (22 of 286) of ICH patients would have qualified for STICH II enrollment. Other treatment options need to be explored for most ICH patients.

Battle's sign is a classical clinical sign that has long been held to be synonymous with fracture of the basal skull. As such the presence of Battle's sign is a strong indicator that a basal skull fracture could be present in the head injured patient, as exemplified by its inclusion as a major risk factor in scoring systems designed to assess the likelihood of basal skull fracture. ⋯ We present a case that describes the occurrence of this classic clinical sign in an unlikely setting and, for the first time since it was described more than 120 years ago, re-examine the pathologic basis for its appearance.

Review Case Reports
Spontaneous spinal epidural hematoma of unknown etiology: case report and literature review.
Our objective is to emphasize the importance of recognizing and rapidly treating spontaneous spinal epidural hematoma (SSEH). SSEH is a pathologic entity traditionally thought to be exceptionally rare but which, in the era of MR imaging, is becoming increasingly prevalent, and which if treated with sufficient rapidity can be completely curable. ⋯ As evidenced in the literature, outcome depends on time to operation and prognosis is impacted by age and preoperative deficit. Because of the high risk of poor outcome without treatment, SSEH should always be a diagnostic consideration in patients whose presentation is even slightly suggestive. Rapid, appropriate treatment of these patients can often lead to complete recovery of function, whereas any delay in appropriate treatment can be catastrophic.

Controlled Clinical Trial
Monitoring with the Somanetics INVOS 5100C after aneurysmal subarachnoid hemorrhage.
Vasospasm is a major cause of morbidity after subarachnoid hemorrhage (SAH), and current screening techniques (angiography, transcranial Doppler [TCD], and clinical examination) have serious limitations. Brain oximetry is a promising noninvasive tool to detect reduced brain oxygenation from vasospasm. ⋯ INVOS rO2 readings are associated with other factors that relate to cerebral oxygen delivery but seem to be of limited use as a screening tool for vasospasm or cerebral infarction after SAH.
