PURPOSE: The purpose of this study was to evaluate the phenomenon of diaschisis in the cerebellum and cerebral certex in patients with pure basal ganglia hemorrhage using cerebral blood flow SPECT. MATERIALS AND METHODS: Twelve patients with pure basal ganglia hemorrhage were studied with Tc-99m ECD brain SPECT Asymmetric index (AI) was calculated in the cerebellum and cerebral cortical regions as |CR-CL|/(CR-CL)x200, where CR and GL and the mean reconstructed counts for the right and left ROIs, respectively. Hypoperfusion was considered to be present when AI was greater than mean+2 SD of 20 control subjects. RESULTS: Mean AI of the cerebellum and cerebral cortical regions in patients with pure basal ganglia hemorrhage was significantly higher than normal controls (p<0.05): Cerebellum (18.68+/-8.94 vs 4.35+/-0.94, mean+/-SD), thalamus (31.91+/-10.61 vs 2.57+/-1.45), basal ganglia (35.94+/-16.15 vs 4.34+/-2.08), parietal (18.94+/-10.69 vs 3.24+/-0.87), frontal (13.60+/-10.8 vs 4.02+/-2.04) and temporal cortex (18.92+/-11.95 vs 5.13+/-1.69). Ten of the 12 patients had significant hypoperfusion in the contralateral cerebellum. Hypoperfusion was also shown in the ipsilateral thalamus (n=12), ipsilateral parietal (n=12), frontal (n=6) and temporal cortex (n=10). CONCLUSION: Crossed cerebellar diaschisis (CCD) and cortical diaschisis may frequently occur in patients with pure basal ganglia hemorrhage, suggesting that CCD can develop without the interruption of corticopontocerebellar pathway.

A 9-year-old boy showed orofacial dyskinesia and psychic symptoms shortly after open heart surgery with deep hypothemia and cardiopulmonary bypass for congenital cyanotic heart disease. The choreothetosis progressed to be generalized and accompanied by mental deterioration. This involuntary movement partially responded only to repetitive administration of sedatives. After 3 month the patient expired with sudden development of ventricular tachycardia and cardiogenic shock.

Streptococcus constellatus (S. constellatus) is a commensal microorganism belonging to the "Streptococcus milleri" group, but may cause infections in different locations in immunocompromised patients. The infection of S. constellatus has high mortality and morbidity due to its tendency to cause abscesses in infected patients, which require immediate surgical drainage for effective treatment. We report on a 72-year-old woman with end stage renal disease, who suffered from dyspnea and general weakness that had developed over 7 days. Chest CT showed loculated pleural effusion. S. constellatus was cultured from exudative pleural effusions and confirmed by an analysis of 16S rRNA sequence. The patient was treated with drainage of pleural effusion and piperacillin/tazobactam for 5 weeks.

PURPOSE: To evaluate the positive effects and problems through clinical and radiological results of cementless bipolar hemiarthroplasty for intertrochanteric fractures above type A2 in the elderly. MATERIALS AND METHODS: From December 2006 to June 2009, 54 bipolar hemiarthroplasties were performed in 54 patients in our hospital. The mean age was 78.8 (67-93) years. Of these cases, 13 were male and 41 were female. The fractures were of type A2.1 in 17 cases, type A2.2 in 23 cases and type A2.3 in 14 cases. There was no walking limitation in 45 patients, but 4 of the remaining 9 patients had walking limitations and used walking aids at their residence. A posterolateral approach as well as cementless femoral stems was used in all the patients. Clinical results were evaluated according to operation time, amount of bleeding, time to resume walking, duration of hospital stay, recovery of walking ability, and complications. Prostheses loss was evaluated on the follow-up radiographs. RESULTS: Twenty-two of 39 patients who had medical co-morbidity had more than two medical co-morbidities. Operations were performed at a mean time of 5.5 days after the fracture. The mean operation time was 95 minutes. The average total amount of bleeding was of 715 cc. Patients began walking at an average of 5.9 days after operation and the average duration of hospital stay was 19.2 days. Sixteen patients (29.6%) died at an average period of 1.6 years after their operation. At the time of discharge, 32 patients (59%) had recovered walking ability, but at the last follow-up compared to the pre-injury status, the recovery rate of walking had decreased to 46% (25 patients). Complications included a deep infection in one case, dislocation in 2 cases and hematoma in 2 cases. The cause of revision was deep infection. There were no revisions due to prosthesis loosening. CONCLUSION: Cementless bipolar hemiarthroplasty for intertrochanteric fractures in the elderly had some problems due to the prolonged operation time and increased amount of bleeding, but it also had advantages including the early return to walking after the operation and decreased hospital stay. It is one of the treatment options for the elderly with unstable intertrochanteric fractures.

OBJECTIVES: Posttraumatic stress disorder(PTSD) has been primarily associated with emotional problems. Recently, however, the impact of PTSD on cognitive processes has interested a growing number of researchers. The current study is aimed at investigating the cognitive aspects of PTSD at both behavioral and neurological levels. METHODS: We recruited individuals with PTSD who survived the Daegu subway explosion in 2003 as well as non-PTSD individuals as a control group. To evaluate the inhibitory processes and the neural mechanisms, we had these individuals perform the negative priming task simultaneously with functional MRI scanning. RESULTS: Behaviorally, the negative priming effect was intact in the control group but was not evident in the PTSD group. In the imaging results, only the PTSD group showed the negative priming effect (i.e., increased activation of the negative priming condition as opposed to the neutral condition) in the dorsolateral prefrontal cortex, anterior cingulate cortex, and inferior temporal gyrus. The PTSD group also showed increased activity for the positive priming condition as opposed to the neutral condition in the claustrum. These results confirm and extend the previous findings that the integrity of the ACC is compromised in the trauma survivors due to disrupted white matter tract. CONCLUSIONS: The current results suggest that deteriorated performance of the PTSD group may be due to the functional problem as well as the structural abnormalities.
