Persistent but reversible coma in encephalitis.

INTRODUCTION: Nontraumatic coma in adults has a poor prognosis, and late recovery of consciousness is unlikely. Functional recovery is usually extremely poor. However, a few nontraumatic comatose patients have shown late recovery of both awareness and function. METHODS: A retrospective survey was conducted by reviewing the medical records of all inpatients to our department during the 1990s. Patients with persistent but reversible nontraumatic coma were identified according to the following criteria: (a) deep coma with a Glasgow Coma Scale (GCS) score of 7 or less on admission; (b) nontraumatic cause; (c) persistence of unconsciousness for longer than 1 month; and (d) subsequent recovery of GCS (total) to normal. The clinical spectrum of patients meeting these criteria was evaluated. RESULTS: Six patients (ages 16-75 years) met the criteria. Viral encephalitis was diagnosed in five (two with herpes simplex virus, two with cytomegalovirus, and one with Epstein-Barr virus or cytomegalovirus). Two young female patients with encephalitis manifested extremely protracted coma persisting for 3 and 18 months, respectively. Complications included nonconvulsive status epilepticus in two patients and relative overdose of clonazepam in one patient. CONCLUSION: Recognition of the clinical spectrum of persistent but reversible nontraumatic coma is important.

Late occurrence of diffuse cerebral swelling after intracerebral hemorrhage in a patient with the HELLP syndrome--Case report.

Hemolysis, elevated liver enzymes, and low platelet count (HELLP) syndrome can occur at any time in the course of pregnancy and is associated with many complications including fatal stroke. A 37-year-old female presented with HELLP syndrome causing an intracerebral hematoma, which was treated by evacuation and mild hypothermia. Unexpected diffuse cerebral swelling occurred on the 15th day of the initially favorable postoperative course. Considerable impairment of consciousness persisted despite conservative therapy. Serial computed tomographic findings indicated delayed cerebral vasospasm as the cause of the swelling. Particularly careful management is required even beyond the first 2 weeks for patients with stroke as a complication of HELLP syndrome.

Do women fare worse? A metaanalysis of gender differences in outcome after traumatic brain injury.

The purpose of this metaanalysis was to investigate possible gender differences in TBI sequelae. The case fatality rates in patients after TBI have previously been shown to be significantly higher in women as compared with men. A quantitative review of published studies of TBI outcome revealed eight studies (20 outcome variables) of TBI in which outcome was reported separately for men and women. Outcome was worse in women than in men for 85% of the measured variables, with an average effect size of -0.15. Although clinical opinion is often that women tend to experience better outcomes than do men after TBI, the opposite pattern was suggested in the results of this metaanalysis. However, this conclusion is limited by the fact that in only a small percentage of the total published reports on TBI outcome was outcome described separately for each sex. A careful, prospective study of sex differences in TBI outcome is clearly needed.

Improved survival after aneurysmal subarachnoid hemorrhage: review of case management during a 12-year period.

OBJECT: Based on the concept that unfavorable clinical outcome after aneurysmal subarachnoid hemorrhage (SAH), to a large extent, is a consequence of all ischemic insults sustained by the brain during the acute phase of the disease, management of patients with SAH changed at the authors' institution in the mid-1980s. The new management principles affected referral guidelines, diagnostic and monitoring methods, and pharmacological and surgical treatment in a neurointensive care setting. The impact of such changes on the outcome of aneurysmal SAH over a longer period of time has not previously been studied in detail. This was the present undertaking. METHODS: The authors analyzed all patients with SAH admitted to the neurosurgery department between 1981 and 1992. This period was divided in two parts, Period A (1981-1986) and Period B (1987-1992), and different aspects of management and outcome were recorded for each period. In total, 1206 patients with SAH (mean age 52 years, 59% females) were admitted; an aneurysm presumably causing the SAH was found in 874 (72%). The 30-day mortality rate decreased from 29% during the first 2 years (1981-1982) to 9% during the last 2 years (1991-1992) (Period A 22%; Period B 10%; p<0.0001) and the 6-month mortality rate decreased from 34 to 15% (Period A 26%; Period B 16%; p<0.001). At follow-up review conducted 2 to 9 years (mean 5.2 years) after SAH occurred, patients were evaluated according to the Glasgow Outcome Scale. Subarachnoid hemorrhage-related poor outcome (vegetative or dead) was reduced (Period A 30%; Period B 18%; p<0.001). There was an increase both in patients with favorable outcome (good recovery and moderate disability) (Period A 61 %; Period B 66%) and in those with severe disability (Period A 9%; Period B 16%; p<0.01). CONCLUSIONS: This study provides evidence that the prognosis for patients with aneurysmal SAH has improved during the last decades. The most striking results were a gradual reduction in mortality rates and improved clinical outcomes in patients with Hunt and Hess Grade I or II SAH and in those with intraventricular hemorrhage. The changes in mortality rates and the clinical outcomes of patients with Hunt and Hess Grades III to V SAH were less conspicuous, although reduced incidences of mortality were seen in some subgroups; however, few survivors subsequently appeared to attain a favorable outcome.

Results of early surgical evacuation of packed intraventricular hemorrhage from aneurysm rupture in patients with poor-grade subarachnoid hemorrhage.

OBJECT: The goal of this study was to evaluate the results of early surgical evacuation of "packed" intraventricular hemorrhage (IVH) in patients with poor-grade subarachnoid hemorrhage (SAH). METHODS: The authors performed surgery within 24 hours after onset of SAH, identified on neuroimaging as a cast distending the ventricular system, in 74 patients with poor-grade SAH (World Federation of Neurosurgical Societies Grades IV and V) without intracerebral hemorrhage. Eighteen of these patients had packed IVH; in these patients the intraventricular clots were extensively evacuated via frontal corticotomy performed under microscopic view. CONCLUSIONS: Overall, 42% of the 74 patients undergoing craniotomy in the acute stage had favorable outcomes, whereas 30% died. Using multivariate analysis, variables significantly associated with favorable outcome in patients with poor-grade SAH included absence of a packed intraventricular clot on computerized tomography scanning; absence of a history of cardiac disease; and a Glasgow Coma Scale score of 11 or 12. None of the 18 patients who had packed IVH had favorable outcomes and seven of these died. In six recently treated patients with packed IVH, which was examined using fluid-attenuated inversion recovery imaging, extensive periventricular brain damage was found both immediately after surgery and during the chronic stage. Accordingly, the authors believe that irreversible periventricular brain damage is already complete immediately after packed IVH occurs.

The Terri Schiavo saga: the making of a tragedy and lessons learned.

The recent case of Terri Schiavo has been an important medical, legal, and ethical controversy. However, much of the public discussion of the tragedy has been based on inaccurate information regarding the facts of the case and the actual legal and ethical issues involved. This article reviews the pertinent aspects of the case and the ethical and legal questions raised and highlights the lessons we should learn from this unique story.

Euthanasia: wrong problem, wrong answer.

The ability of medical technology to prolong life has created unease with current law governing the protection of life. Adopting and advertising standards of approved medical practice in this area may remove the perceived need for euthanasia.
