To evaluate the cerebral hemodynamics in cryptococcal meningitis (CM) patients using non-invasive studies. Serial trans-cranial color-coded sonography (TCCS) and magnetic resonance angiography (MRA) studies were performed to measure the cerebral vasculopathy of 12 HIV-negative CM patients. With TCCS, 8 of the 22 middle cerebral arteries (MCAs) showed stenotic velocities, whereas the time-mean velocity (V(mean)) of the 20 anterior cerebral arteries (ACAs), 22 posterior cerebral arteries (PCAs), and 12 basilar arteries (BAs) did not. In total, five patients had stenotic velocities, three of whom had bilateral M1 stenosis (

The clinical data and cerebrospinal fluid (CSF) 14-3-3-gamma protein detection of eight adult HIV-negative cryptococcal meningitis (CM) cases were examined. The eight cases included six males and two females aged 35-70 years (mean = 49.8 years). The duration between the onset of CM symptoms and the first CSF study ranged from 1 to 60 days. Initial neuroimaging study was abnormal in 87.5% (7/8) of the cases. All the eight had positive initial and subsequent follow-up CSF 14-3-3-gamma protein detection. The densitometric values of CSF 14-3-3-gamma protein were not correlated with either the CSF white blood cell counts or the therapeutic results. The therapeutic results showed that three cases died and five survived. Significant neurologic deficits were shown in 60% (3/5) of the survivors. This study revealed that HIV-negative CM patients have elevated CSF 14-3-3-gamma protein levels, and that this level is not changed with a short-term treatment.

To determine the factors predictive of fatality in massive middle cerebral artery (MCA) territory infarction and outcome of decompressive hemicraniectomy, 62 patients who were retrospectively verified with first event massive MCA infarctions were enrolled in this study. Amongst them, 21 received decompressive hemicraniectomy during hospitalization. Clinical data between early and late hemicraniectomy groups were also compared. Significant deterioration occurred in 40 cases, 21 of whom received decompressive hemicraniectomy. The other 19 received conservative treatment. The mortality rate of these 40 cases between decompressive hemicraniectomy and conservative treatment was 29% (six of 21) and 42% (eight of 19), respectively. Factors that predicted fatalities in our massive MCA infarction patients with or without decompressive hemicraniectomy were total scores of baseline GCS at the time of admission, associated with coronary artery diseases, and significant deterioration during hospitalization. This study confirms the lifesaving procedure of hemicraniectomy that prevents death in patients deteriorating because of cerebral edema after infarction, although it may produce severe disability with an unacceptably poor quality of life in survival. Despite high mortality and morbidity, decompressive hemicraniectomy to prevent cerebral herniation when significant deterioration is demonstrated are essential for maximizing the potential for survival.
