Comparative Study
[Effects of traumatic subarachnoid hemorrhage on pathological properties in diffuse brain injury: a comparison with aneurysmal subarachnoid hemorrhage].
As a result of recent advances in continuous monitoring equipment, it has been reported that vasospasm (VS) and delayed ischemic neurological deficit (DIND) occur as frequently in traumatic subarachnoid hemorrhage (TSAH) as in subarachnoid hemorrhage due to ruptured intracranial aneurysm (ASAH), and these VS and DIND have been reported to affect the outcome of TSAH adversely in many cases. When we compared TSAH secondary to diffuse brain injury (DBI) with ASAH, however, these two conditions were evidently different from each other in nature. Then we compared laboratory data, clinical course, and outcomes of TSAH associated with DBI with those of ASAH, to determine whether TSAH results in poor outcomes of DBI. ⋯ The outcome of TSAH was, however, significantly poorer than that of ASAH. When SAH was traumatic, it disappeared by the time VS developed and, in addition, changes in CBF and the form and incidence rate of LDAs were different from those in ASAH. We concluded that, although TSAH is an adverse prognostic factor for DBI, it does not contribute to poor outcomes of DBI by giving rise to DIND caused by VS.

In medical services where acute accident patients are encountered, general and traumatic surgeons are faced with the problem of treating severe head and brain injuries. In the Department of Surgery at the University Hospital in Munich, we have been performing neurotraumatological treatment since 1983. We had 162 patients with severe head and brain injuries, 95 intracerebral contusional bleeding, 8 depression fractures, and 3 hygromas. ⋯ Comparison with other investigations in departments of neurosurgical surgery in the United States suggest that our results reflect a similar outcome (according to Jennet and Bond's outcome scale: 1 cured; 2 slightly; 3 severely handicapped; 4 vegetative state; 5 expired). The Traumatic Coma Data Bank (1991) recorded the outcome of severe head and brain injuries as follows: 1, 27%; 2, 16%; 3, 16%; 4, 5%; 5, 39%. Organization procedures and treatment strategies are suggested.

Randomized Controlled Trial Multicenter Study Clinical Trial
The safety, tolerability, and pharmacokinetics of fosphenytoin after intramuscular and intravenous administration in neurosurgery patients.
To evaluate the safety, tolerability, and pharmacokinetic profile of fosphenytoin, a water-soluble phenytoin prodrug, after intramuscular and intravenous administration. ⋯ Fosphenytoin can be administered intramuscularly and intravenously in neurosurgical patients to achieve and maintain therapeutic phenytoin concentrations for up to 14 days. Both routes are safe and well tolerated. Intravenous fosphenytoin is significantly better tolerated than intravenous phenytoin sodium in this patient subset.

Identification of static and dynamic postural instability following traumatic brain injury.
Quantitative evaluation of static and dynamic aspects of postural instability as a long-term consequence of traumatic brain injury (TBI). ⋯ A long-term overall reduction in both static and dynamic control of posture can be present after TBI, even in patients without clear neurological deficits. Force-plate recordings can identify such (latent) balance problems. Visual deprivation during quiet standing appears a simple, sensitive test for postural instability related to sensory integration deficits.
