Impact of Neurointensivist Co-Management in a Semiclosed Neurocritical-Care Unit

Background@#and Purpose: The importance of the specialized management of neurocritical patients is being increasingly recognized. We evaluated the impact of neurointensivist comanagement on the clinical outcomes (particularly the mortality rate) of neurocritical patients admitted to a semiclosed neurocritical-care unit (NCU). @*Methods@#We retrospectively included neurocritical patients admitted to the NCU between March 2015 and February 2018. We analyzed the clinical data and compared the outcomes between patients admitted before and after the initiation of neurointensivist co-management in March 2016. @*Results@#There were 1,785 patients admitted to the NCU during the study period. Patients younger than 18 years (n=28) or discharged within 48 hours (n=200) were excluded. The 1,557 remaining patients comprised 590 and 967 who were admitted to the NCU before and after the initiation of co-management, respectively. Patients admitted under neurointensivist co-management were older and had higher Acute Physiologic Assessment and Chronic Health Evaluation II scores. The 30-day mortality rate was significantly lower after neurointensivist co-management (p=0.042). A multivariate logistic regression analysis demonstrated that neurointensivist co-management significantly reduced mortality rates in the NCU and in the hospital overall [odds ratio=0.590 (p=0.002) and 0.585 (p=0.001), respectively]. @*Conclusions@#Despite the higher severity of the condition during neurointensivist co-management, co-management significantly improved clinical outcomes (including the mortality rate) in neurocritical patients.

Extended Use of Hypothermia in Elderly Patients with Malignant Cerebral Edema as an Alternative to Hemicraniectomy / 대한뇌졸중학회지

BACKGROUND AND PURPOSE: The use of decompressive hemicraniectomy (DHC) for the treatment of malignant cerebral edema can decrease mortality rates. However, this benefit is not sufficient to justify its use in elderly patients. We investigated the effects of therapeutic hypothermia (TH) on safety, feasibility, and functional outcomes in elderly patients with malignant middle cerebral artery (MCA) infarcts. METHODS: Elderly patients 60 years of age and older with infarcts affecting more than two-thirds of the MCA territory were included. Patients who could not receive DHC were treated with TH. Hypothermia was started within 72 hours of symptom onset and was maintained for a minimum of 72 hours with a target temperature of 33°C. Modified Rankin Scale (mRS) scores at 3 months following treatment and complications of TH were used as functional outcomes. RESULTS: Eleven patients with a median age of 76 years and a median National Institutes of Health Stroke Scale score of 18 were treated with TH. The median time from symptom onset to initiation of TH was 30.3±23.0 hours and TH was maintained for a median of 76.7±57.1 hours. Shivering (100%) and electrolyte imbalance (82%) were frequent complications. Two patients died (18%). The mean mRS score 3 months following treatment was 4.9±0.8. CONCLUSIONS: Our results suggest that extended use of hypothermia is safe and feasible for elderly patients with large hemispheric infarctions. Hypothermia may be considered as a therapeutic alternative to DHC in elderly individuals. Further studies are required to validate our findings.

Balo's Concentric Sclerosis in a Patient with Previous Recurrent Optic Neuritis

Balo's concentric sclerosis is regarded as a rare variant of multiple sclerosis. Traditionally, Balo's concentric sclerosis was a post-mortem diagnosis, but the recent introduction of brain magnetic resonance imaging (MRI) scans may allow noninvasive access without biopsy. Brain MRI findings of Balo's concentric sclerosis is characteristic concentric configuration of alternating bands of white matter of different pathology, with relatively preserved myelination alternating with regions of demyelination in the cerebral white matter. We report a case of Balo's concentric sclerosis with recurrent optic neuritis.

Meningitis-Retention Syndrome

Although aseptic meningitis is a common neurological disorder, a combination of acute urinary retention and aseptic meningitis has been recognized rarely. To our knowledge, only a few case reports are available on this combination and the underlying pathology remains unclear. We reported on a patient showing acute urinary retention and aseptic meningitis with a review of the literatures.
