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.

BACKGROUND: To evaluate the effectiveness of minimally invasive surgery total hip arthroplasty (THA) using the two-incision technique as described by Mears. METHODS: From January 2003 to December 2006, sixty-four patients underwent total hip arthroplasty using the one-incision (group I) and two-incision (group II) technique by one surgeon. There were 34 hips in group I and 30 hips in group II. There was no difference in age, gender, and causes of THA between the two groups. We evaluated the operation time, bleeding amount, incision length, ambulation, hospital stay, and complications between the two groups. RESULTS: There was no difference in the bleeding amount between the two groups. Operation time was longer in the two-incision group than in the one-incision group. Operation time of the two-incision technique could be reduced after 15 cases. Patients started ambulation after surgery earlier in group II than group I, and the hospital stay was shorter in group II than in group I. There was no difference in clinical results between the two groups. There was no difference in component position of the acetabular cup and femoral stem between the two groups. Intraoperative periprosthetic fracture occurred in four cases (13.3%) in group II. CONCLUSIONS: Two-incision THA has the advantage of rapid recovery and shorter hospital stay. However, longer operation time and a high complication rate compared to one-incision are problems that need to be solved in the two-incision technique.

The aim of this study was to investigate whether green tea extract (GTE) has the protective effects on excess L-arginine induced toxicity in human mesangial cell. Human mesangial cells treated with L-arginine were cultured on Dulbecco's modified eagle medium in the presence and absence of inducible nitric oxide synthase (iNOS) inhibitor and GTE. The cell proliferation was determined by 3 (4,5-dimethylthiazol- 2-yl)-2, 5-diphengltetrqzolium bromide, a tetrazole assay. The iNOS mRNA and its protein expression were detected by reverse transcription polymerase chain reaction and Western blot, respectively. The concentration of nitric oxide (NO) was measured by NO enzyme-linced immuno sorbent assay kit. L-arginine significantly inhibited the proliferation of human mesangial cells, and induced the secretion of NO to the media. NO production by L-arginine was significantly suppressed by GTE and iNOS inhibitor (p<0.01). The expression level of iNOS mRNA and its protein that was significantly increased by L-arginine was decreased by iNOS inhibitor but not by GTE. GTE protected the mesangial cells from the NO-mediated cytotoxicity by scavenging the NO rather than by iNOS gene expression. Therefore, we conclude that GTE has some protective effect for renal cells against oxidative injury possibly by polyphenols contained in GTE.

Extraosseous extradural tuberculosis of the spine is rare entity. A 21-year-old man with low back pain, left-sided sciatica & motor weakness was admitted. Simple X-ray were normal. At operation, extradural, extraosseous granuation tissue were removed, which proved upon histologic examination to be tuberculous granulomas. The authors report a rare case of extraosseous tuberculoma in the posterior extradural space of whole lumbar region with review of literatures.

The aim of this study was to evaluate the radiopacity and cytotoxicity of three resin-based (AH 26, EZ fill and AD Seal), a zinc oxide-eugenol-based (ZOB Seal), and a calcium hydroxide-based (Sealapex) root canal sealers. Specimens, 10 mm in diameter and 1 mm in thickness, were radiographed simultaneously with an aluminum step wedge using occlusal films, according to ISO 6876/2001 standards. Radiographs were digitized, and the radiopacity of sealers was compared to the different thicknesses of the aluminum step wedge, using the Scion image software. Using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, the cytotoxicity of each material was determined in immortalized human periodontal ligament (IPDL) cells. The results demonstrated that EZ fill was the most radiopaque sealer, while Sealapex was the least radiopaque (p < 0.05). AH 26, AD Seal and ZOB Seal presented intermediate radiopacity values. All the materials evaluated, except for Sealapex, presented the minimum radiopacity required by ISO standards. The cell viabilities of resin-based root canal sealers were statistically higher than that of other type of root canal sealers through the all experimental time. Further, EZ fill showed statistically lower cell viability in 24 and 48 hours compared to AD Seal and in 72 hours compared to all other resin-based root canal sealers. However, there was no correlation between the radiopacity and cytotoxicity of three resin-based root canals sealers (p > 0.05). These results indicate that resin-based root canal sealer is more biocompatible and has advantage in terms of radiopacity.
