EFFECTS OF 10 WEEKS TRAINING PROGRAM ON LOWER EXTREMITY STRENGTH AND VERTICAL REACTION FORCE DURING SIT-TO-STAND IN CHRONIC STROKE PATIENTS

The purpose of this study was to investigate the effects of 10 weeks training program on lower extremity strength and' vertical reaction force during sit-to-stand movement in chronic stroke patients. Maximum vertical ground reaction force, difference of vertical ground reaction force between left and right foot, COP in anteriorposterior and mediolateral direction did not show any significant time main effect. However, the difference of body weight distribution between the left and right foot was decreased in experimental group after training. The peak torque generated by the flexors of the paretic limb at 60o /sec and 180o/sec in experimental group changed from baseline, an increases of 30.23% and 24.09%, respectively. These results appear that 10 weeks training program improves sit-to-stand movement and lower extremity strength in chronic stroke patients

A simple and accurate SNP scoring strategy based on typeIIS restriction endonuclease cleavage and matrix-assisted laser desorption/ionization mass spectrometry

<p>Abstract</p> <p>Background</p> <p>We describe the development of a novel matrix-assisted laser desorption ionization time-of-flight (MALDI-TOF)-based single nucleotide polymorphism (SNP) scoring strategy, termed Restriction Fragment Mass Polymorphism (RFMP) that is suitable for genotyping variations in a simple, accurate, and high-throughput manner. The assay is based on polymerase chain reaction (PCR) amplification and mass measurement of oligonucleotides containing a polymorphic base, to which a typeIIS restriction endonuclease recognition was introduced by PCR amplification. Enzymatic cleavage of the products leads to excision of oligonucleotide fragments representing base variation of the polymorphic site whose masses were determined by MALDI-TOF MS.</p> <p>Results</p> <p>The assay represents an improvement over previous methods because it relies on the direct mass determination of PCR products rather than on an indirect analysis, where a base-extended or fluorescent report tag is interpreted. The RFMP strategy is simple and straightforward, requiring one restriction digestion reaction following target amplification in a single vessel. With this technology, genotypes are generated with a high call rate (99.6%) and high accuracy (99.8%) as determined by independent sequencing.</p> <p>Conclusion</p> <p>The simplicity, accuracy and amenability to high-throughput screening analysis should make the RFMP assay suitable for large-scale genotype association study as well as clinical genotyping in laboratories.</p

Postoperative Electroencephalogram for Follow up of Pediatric Moyamoya Disease

It is well known that the electroencephalographic finding in patients with moyamoya disease demonstrates the characteristic "re-build up" phenomenon a few minutes after hyperventilation. To evaluate the usefulness of an electroencephalogram (EEG) in the postoperative management of children with moyamoya disease, we studied the presence or absence of improvement in the clinical, single photon emission computed tomography (SPECT) and EEG findings, before and after surgery. Twenty-two patients, who underwent indirect revascularization surgery for moyamoya disease, were included in our study. Clinical improvement was assessed as the disappearance or decrease of a transient ischemic attack or headache. The findings on the EEG and SPECT were considered improved when the re-build up phenomenon was absent and when there was improvement in the cerebrovascular reserve as a result of the acetazolamide challenge test. The statistical correlation analysis for both clinical and EEG improvement were consistent (kappa value=0.409, p<0.05). However, the result from the clinical and SPECT improvement as well as that from EEG and SPECT improvement were not statistically significant. Our results suggest that EEG can be used as a noninvasive and simple follow-up test for moyamoya disease after indirect revascularization surgery if the hyperventilation procedure is effectively performed during EEG recording

Phlebosclerotic Colitis in a Cirrhotic Patient with Portal Hypertension: The First Case in Korea

Phlebosclerotic colitis is a rare form of ischemic colitis characterized by the thickening of the wall of the affected colon due to fibrous degeneration of submucosal layer of colon and fibrotic obstruction of the colono-mesenteric vein, resulting in the disturbance of venous return from the colon. The pathogenic mechanism of this entity remains unknown but chronic liver disease with portal hypertension is maybe thought to be one of the speculated mechanisms. Here we first report the case of surgically confirmed phlebosclerotic colitis, that was in the early stage but showed the aggressive nature, in a 61-yr-old cirrhotic patients with portal hypertension in Korea

A case of blue rubber bleb nevus syndrome

Blue rubber bleb nevus syndrome is a rare disorder that is characterized by multiple recurrent vascular malformations, such as hemangioma, and these primarily involve the skin and the gastrointestinal tract. It may also involve the brain, liver, lungs, and skeletal muscles. A 14-year-old female visited our hospital with a chief complaint of dizziness; upon examination, we found multiple recurrent hemangiomas on the skin and gastrointestinal tract. We were able to diagnose her as suffering from blue rubber bleb nevus syndrome and we treated her with methylprednisolone (2 mg/kg/day for 1 month and 1 mg/kg/day for additional 3 months). We report on this case along with a review of the literature

Treatment Outcomes with CHOP Chemotherapy in Adult Patients with Hemophagocytic Lymphohistiocytosis

The objective of the current study was to investigate the treatment outcomes for the use of cyclophosphamide, adriamycin, vincristine, and prednisolone (CHOP) chemotherapy in adult patients with hemophagocytic lymphohistiocytosis (HLH). Seventeen HLH patients older than 18 yr of age were treated with CHOP chemotherapy. A response evaluation was conducted for every two cycles of chemotherapy. With CHOP chemotherapy, complete response was achieved for 7/17 patients (41.2%), a partial response for 3/17 patients (17.6%), and the overall response rate was 58.8%. The median response duration (RD) was not reached and the 2-yr RD rate was 68.6%, with a median follow-up of 100 weeks. Median overall survival (OS) was 18 weeks (95% CI, 6-30 weeks) and the 2-yr OS rate was 43.9%. Reported grade 3 or 4 non-hematological toxicities were increased serum liver enzyme levels and stomatitis. Grade 3 or 4 hematological toxicities were leukopenia (50.8%), anemia (20%), and thrombocytopenia (33.9%). Neutropenic fever was observed in 21.6% of patients (14/65 cycles), and most of the cases were resolved with supportive care including treatment with broad-spectrum antibiotics. CHOP chemotherapy seems to be effective in adult HLH patients and the toxicities are manageable
