    ABSTRACT: Increased plasma nuclear and mitochondrial DNA levels may be connected to disease severity following spontaneous intra-cerebral haemorrhage (ICH). This study tested the hypothesis that plasma nuclear and mitochondrial DNA levels are substantially increased in acute ICH and can predict treatment outcomes. Serial plasma nuclear and mitochondrial DNA levels were examined in 60 consecutive patients admitted within 24 h after onset of spontaneous ICH and in 60 volunteer control subjects. Additional samples were obtained on days 4, 7, 10, and 14 after onset of ICH regardless of clinical deterioration. Only plasma nuclear DNA, not plasma mitochondrial DNA, levels in patients with spontaneous ICH significantly correlated with Glasgow Coma Scale (GCS) (r = −0.467, P = 0.001) and ICH volume (r = 0.515, P ≤ 0.001) on presentation. Plasma nuclear DNA levels increased significantly from day 1 to day 7 in patients with poor outcome. Higher plasma nuclear DNA levels (cut-off value >18.7 ng/ml) on presentation were associated with poor outcomes in spontaneous ICH patients. Plasma nuclear DNA levels reflect the severity of cerebral damage such that higher levels are associated with poorer outcome. Plasma nuclear DNA level can be considered a neuropathologic marker of acute spontaneous ICH.

    ABSTRACT: Chronic liver disease frequently includes cognitive and movement disorders, suggesting an alteration of the striatum. With the exception of hyperintensities evident on T1-weighted images indicative of Mn deposition, radiographic findings of the BG are nonspecific. Volumetric and morphometric analysis of DGM is limited. Whether DGM undergoes degeneration and whether this change is associated with pallidal hyperintensity and cognitive performance are currently unknown in patients with cirrhosis. The DGM volumes of 28 patients with chronic cirrhosis and 28 control patients were compared. Using 3D high-resolution MR images, the volume and shape of each structure were automatically analyzed by the FSL. Correlations between the DGM volume and other clinical variables, including the pallidal signal intensity, were assessed by multiple regression analysis. Patients with Child B and Child C liver disease had significantly smaller bilateral putaminal volumes than control patients, and patients with Child C also demonstrated smaller left caudate nucleus and left amygdala volumes than control patients. Pallidal hyperintensity correlated with smaller striatum volume, which was linearly related to worse cognitive performance. The nonuniform distributed shape abnormalities in the striatum further support the ascending spiral interconnecting theory of the striatum. These findings strongly suggest lower DGM volume develops according to the severity of the liver cirrhosis. The Mn deposition might contribute the striatum deficit. These findings support the value of additional psychomotor research associated with liver cirrhosis.

    ABSTRACT: The high rate of neuropsychologic sequelae in CM survivors indicates that initial antifungal therapy is far from being satisfactory. This prospective cross-sectional study applied DTI on HIV-negative CM patients to determine whether microstructural changes in brain tissue are associated with subsequent cognitive symptoms. Fifteen patients with HIV-negative CM and 15 sex- and age-matched healthy volunteers were evaluated and compared. All underwent complete medical and neurologic examinations and neuropsychologic testing. Brain DTI was obtained to derive the FA and ADC of several brain regions. Correlations among DTI parameters, neuropsychologic rating scores, and cryptococcal-antigen titer in CSF were analyzed. Significant ADC values increased and FA values decreased in HIV-negative CM patients in multiple selected regions of interest, including the genus of the corpus callosum and the frontal, parietal, orbito-frontal, and periventricular white matter and lentiform nucleus. Higher CSF cryptococcal-antigen titer on admission was associated with poorer DTI parameters (r = -0.666, P = .018), which were linearly related to worse cognitive performance during follow-up. The decline in brain DTI parameters in the associated brain areas indicates an HIV-negative CM microstructural pathology that is related to neuropsychologic consequences.

    ABSTRACT: Clin Microbiol Infect 2011; 17: 615–620 Although treatment of brain abscess requires a combination of antimicrobials and surgical intervention for the infected foci, nonsurgical, empirical treatment is possible and efficient in selected groups of patients. A total of 31 patients were enrolled in this 22-year retrospective study. We describe our therapeutic experiences and attempt to analyze the risk factors that were predictive of therapeutic outcomes. Multiple logistic regression was used to evaluate the relationships between baseline clinical factors and therapeutic outcome during the study period. Of these 31 patients, 25 had community-acquired infections, whereas the other six had nosocomially-acquired infections. Thirteen cases (42%) had a single brain abscess and the other 18 cases (58%) had multiple brain abscesses. Furthermore, the association of bacterial meningitis and brain abscess was found in 81% (25/31) of cases. The overall case fatality rate was 48% (15/31). Significant risk factors for poor outcomes included Glasgow coma scale (GCS) at presentation, presence of septic shock and neck stiffness. In addition, each reduction of one point on the GCS increased the poor outcome rate by 28%. The findings of the study demonstrate that both a higher mortality rate (48%) and worse outcomes were found in this select group of patients. Among the significant prognostic factors, a lower mean GCS at presentation was a major determinant of poor outcome.

    ABSTRACT: White matter (WM) injury in carbon monoxide (CO) intoxication is thought to be related to delayed cognitive sequelae. To determine if microstructural changes in WM are responsible for the delayed onset of cognitive symptoms, we performed diffusion tensor imaging (DTI) in patients with CO intoxication. DTI was performed in 14 patients with delayed sequelae after CO intoxication and in 16 sex- and age-matched healthy volunteers. The fractional anisotropy (FA) and apparent diffusion coefficient (ADC) of several WM regions were measured. We also determined the correlation between FA of the selected WM and neuropsychological rating scores for the CO intoxication group. FA of patients with CO intoxication decreased in the corpus callosum, orbitofrontal WM, high frontal WM, parietal WM, and temporal lobes in comparison with the corresponding regions of healthy controls. FA of the WM in the occipital lobe and internal capsule of patients was not significantly different from that in controls. ADCs of all measured WM increased significantly in patients exposed to CO. High correlations were found between the FA of all selected WM and the Mini-Mental State Examination score (gamma = 0.631, P = .016) and the digit span backward task (gamma = 0.759, P = .001). CO intoxication may cause FA decline in associated cortical areas. This observation indicates microstructural WM pathology in CO intoxication, which is related to delayed cognitive encephalopathy.

    ABSTRACT: Carcinoembryonic antigen (CEA) titre elevation is sometimes found in benign diseases, such as gastro-intestinal tract inflammatory disease and chronic obstructive pulmonary disease; however, very high CEA titre is rarely encountered in benign pulmonary disease. A 36-yr-old female, who had suffered from body weight loss, was found to have high serum CEA titre (60.8 ng.mL(-1)). Image studies revealed one pulmonary tumour at the left lower lobe, satellite nodules and mediastinal lymphadenopathy. Left lower lobectomy and lymph node dissection were performed for suspicious pulmonary malignancy. The pathological examination revealed that the tumourous lesion was composed of small and fragmented foreign bodies, fibrinopurulent exudate and heavy eosinophils. The bronchial epithelium was characterised by goblet cell hyperplasia and CEA overexpression. The remaining lung parenchyma possessed similar foreign body reaction. The patient's medical history was reviewed and it was found that she had spread propolis topically on nasal mucosa as an adjuvant therapy to asthma for 6 months prior to this medical event. The CEA titre decreased after the operation to 14.2 and 7.88 ng.mL(-1) after 2 weeks and 6 months, respectively. Propolis is used widely in folk medicine but it also has strong sensitising potential. One rare case of propolis aspiration is reported with presentation mimicking lung cancer.
