PURPOSE: The objective of this study was to evaluate the advantages of a laparoscopic technique for the treatment of intussusception in children with repeated hydrostatic reduction failure. METHODS: Between April 2001 and March 2002, twenty one children with intussusception were treated. Eleven patients, with repeated barium reduction failure, underwent a laparoscopic reduction. The type of intussusception, operative time, postoperative hospital stay, and conversion rate, were prospectively examined. RESULTS: The laparoscopic reduction was successful in 8 patients (72.7%), with a conversion to an open procedure occurring in 3 (27.3%). In the 8 successful laparoscopic reduction cases, the average operative time and postoperative hospital stay were 66 minutes and 3 days, respectively. Seven cases were of the ileo-colic type of intussusception and remaining one was of the ileo-ileo-colic type. There were no mortalities or intraoperative complications. CONCLUSION: Intussusception in number of children with hydrostatic reduction failure could be reduced with the laparoscopic technique. The laparoscopic procedure for intussusception was safe and resulted in the avoidance of open surgery.

OBJECTIVES: The primary aim of this study was to determine whether 18F-FDG-PET/CT (PET/CT) scans provide additional diagnostic information in addition to the direct laryngoscopic examination (L/E) and contrast-enhanced CT (CT) in patients with glottic cancer during the initial evaluation. METHODS: Fifty-five consecutive patients with glottic cancer of the larynx that had L/E, CT and PET/CT were enrolled. The diagnostic value of each modality was compared for their accuracy in predicting the extent of the primary tumors on sub-site based analysis and the final tumor staging. The reference standards were either the surgical pathology findings or clinical/radiological follow-up outcome. Changes in patient care based on PET/CT results were compared with the treatment decisions based on L/E with CT. RESULTS: For primary tumor sub-site based analysis, the sensitivity was significantly higher for L/E (92.8%) than for PET/CT (79.4%, P=0.028). The comparisons between L/E vs. CT and CT vs. PET/CT did not reach statistical significance. As an initial tumor-staging method the L/E had a diagnostic accuracy of 76.4%, compared to 61.8% for CT and 41.8% for PET/CT. The L/E and CT were better than the PET/CT (P=0.0009 and 0.049) for the initial TNM staging. PET/CT scanning changed the clinical decision-making based on the L/E with CT results in 12.7% of cases, of whom 5.5% had no additional PET/CT related benefit. CONCLUSION: Conclusion. The results of this study showed that PET/CT imaging added no clinical information benefit compared to the L/E and CT for the initial evaluation of patients with glottic cancer.

Psoas abscesses are rare clinical entities complicating Crohn's disease (CD). However, psoas abscesses can cause poor outcomes because the diagnosis is frequently delayed due to the non-specific clinical features. Recently, we managed a case of a huge iliopsoas abscess in a 21-year-old man with a 4-year history of CD who presented with a limping gait and flexion contractures of the sacroiliac joint. Notably, the iliopsoas abscess developed during induction treatment with infliximab. The patient was successfully treated with antibiotics, surgical drainage, and a right hemicolectomy. Herein we present the case with a brief review of the literature.

BACKGROUND: We performed the study on the changes of beta2-microglobulin(beta2M) clearance and urea reduction ratio after reuse of dialyzers with three different membranes. METHODS: 9 patients who had received regular hemodialysis more than five years were enrolled. Three kinds of dialyzer membrane were used; i.e. : Two of them were high-flux and the other was low-flux. Dialyzer reprocessing was performed by an automated machine using glutaraldehyde and bleach. Each dialyzer was reused 10 times. Solute clearance was determined for each dialyzer after the 1st, 5th, 8th and 10th reuse. RESULTS: Urea clearance was well maintained after reuse with both high-flux and low-flux membrane but beta2M clearance was significantly greater with high-flux dialyzers than low-flux dialyzer. Effects of each dialyzer reuse on beta2M clearance showed no significant decrease until the 10th reuse and no significant difference in beta2M clearance between the two high-flux dialyzers(polyamide vs PEPA membrane, p= 0.197). CONCLUSION: Reuse of dialyzers was cost-effective. After reuse of dialyzer, clearance of solute was maintained in both small and large solutes until the 10 th reuse. Further study is needed regarding the maintenance of solute clearance with increased number of reuses.

Up to 40% of patients with anti-glomerular basement membrane (GBM) disease, which is a rare autoimmune disorder usually manifesting as rapidly progressive glomerulonephritis (RPGN), are positive for circulating anti-neutrophil cytoplasmic antibody (ANCA). Many previous reports showed poor outcomes in these "double-positive" patients. We report a patient with perinuclear (p)-ANCA positive anti-GBM disease who presented with RPGN and required hemodialysis. Plasmapheresis and steroid and cyclophosphamide therapy were initiated following renal biopsy and resulted in normalization of anti-GBM antibody and p-ANCA titers, recovery of renal function, and discontinuation of hemodialysis. This case suggests that aggressive immunosuppression with plasmapheresis in patients who are p-ANCA positive with anti-GBM disease should be considered, even in those with severe renal dysfunction.

Lymphangioma is a benign vascular lesion that shows the characteristics of subepithelial tumor, which can proliferate in the lymphatic system. Only a few cases of multiple lymphangimas of the colon, the so called "colonic lymphanigomatosis", have been currently reported on the medical literature. Because lymphangioma is absolutely a benign tumor, it does not require any specific treatment, except for rare disease-related symptoms or complications such as anemia, intussusception and protein-losing enteropathy. Endoscopic resection for this tumor has sometimes been performed for both diagnostic and therapeutic purposes. We recently experienced a case of multiple colonic lymphangomas that arose in the ascending colon of a 46-year-old male patient and these lesions were found during performance of colonoscopy. The final diagnosis was confirmed by a pathologic examination of the specimen that was obtained via endoscopic resection. Follow-up colonoscopy at 1 year after the initial examination showed complete resolution of the previously noted lesions without any specific treatment. We report here on a very rare case of colonic lymphangiomatosis along with a brief review of the relevant literature.

BACKGROUND: Astrocytes, representing a major non-neuronal cell population in the central nervous system (CNS), contain opioid receptors and are actively involved in several brain functions. This study is designed to evaluate the effects by which morphine contributes to cytotoxicity of nitric oxide (NO) species including NO and peroxynitrite (ONOO(-)) in primary astrocytes isolated from the cerebral cortexes of 1 - 2 day Sprague-Dawley rats. METHODS: The cultured cells were pretreated with morphine and exposed to 3-morpholinosydnonimine (SIN-1) which simultaneously generates NO and superoxide, thus possibly forming peroxynitrite. The cell damage was assessed by using an MTT (methylthizol-2-yl-2, 5-diphenyl, tetrazolium bromide) assay. Morphological nuclear changes of the cells after exposure to SIN-1 for 24 hours was evaluated by using 4', 6-diamidino-2-phenylindole (DAPI) staining. RESULTS: Morphine significantly protected primary rat astrocytes in a dose-dependent manner from the death mediated by sodium nitroprusside (SNP), a donor of nitric oxide, and SIN-1. Moreover, it was found that naloxone antagonized the protective effect of morphine on SIN-1-induced cell death, revealed as apoptosis by the occurrence of morphological nuclear changes characteristic of apoptosis. Morphine also inhibited the nuclear condensation of SIN-1-treated cells, however the action of morphine was antagonized by pretreatment of naloxone. The protective role of morphine on SIN-1-induced cytotoxicity was inhibited by DL-Buthionine-[S, R]-sulfoximine (BSO). Furthermore, the effects of morphine on SIN-1-induced cytotoxicity were blocked by pretreatment of Gi protein inhibitor, pertussis toxin, and phosphoinositide 3-kinase (PI3 kinase) inhibitors, Wortmannin and LY294002. CONCLUSIONS: These results suggest that morphine may protect primary rat astrocytes from NO species via the signaling cascades involving G-protein and PI3-kinase, and possibly regulates the anti-oxidant, glutathione (GSH).
