PURPOSE: To report a case of bacterial keratitis caused by Hafnia alvei after using a contact lens in a patient with graft-versus-host disease. CASE SUMMARY: A 47-year-old male patient presented with a corneal ulcer. The patient had been wearing a therapeutic contact lens for a month because of severe dry eye syndrome and filament removal due to filamentary keratitis. The patient had been taking moxifloxacin to prevent infection, but had not for the previous 7 days. The corneal ulcer occurred at the 11 o'clock direction in the peripheral cornea accompanied by corneal epithelial defect and stromal infiltration. The corneal scraping and culture yielded Hafnia alvei, which is susceptible to ceftazidime, levofloxacin and moxifloxacin. There was no systemic signs or symptoms to suspect systemic infection. After treatment with a topical antibiotic agent, the patient's eye condition improved with only mild corneal opacity remaining. CONCLUSIONS: Hafnia alvei infection rarely occurs in humans but should be considered as a potential causal pathogen in immunosuppressed patients.

A 68-year-old man developed mild quadriparesis 1 month prior to presentation. At 4 days before presentation, he developed dysarthria and more severe quadriparesis, predominantly on the left side of the body. MRI revealed edematous lesions in the medulla and throughout the spinal cord. Angiography showed a right tentorial dural arteriovenous fistula (DAVF). Despite successful treatment achieved by endovascular embolization, there was no improvement in the weakness of either leg. Early diagnosis of tentorial DAVF is important to prevent neurological complications such as encephalomyelopathy and hemorrhage.

PURPOSE: To determine the relation between the initial plasma cytokine response and the neurological prognosis in term infants with severe fetal distress. METHODS: Infants with severe fetal distress at birth (n=23) were studied prospectively. Cytokine concentrations were measured from umbilical cord blood at 3 and 12 hours of life by enzyme-linked immunosorbent assays for interleukin (IL)-1beta, IL-6, and IL-18. The study groups were divided into good (n=14) or poor prognostic group (n=9) according to survival and presence of cerebral palsy (CP) later and correlations with afore mentioned cytokine levels were determined. RESULTS: Cord blood IL-1beta and IL-18 concentrations were similar in both groups. However, infants with poor prognosis had significantly higher median (range) IL-6 concentration than infants with good prognosis at 3 hours [323.6 (32.6-812.8) vs. 38.4 (6.3- 322.7) pg/mL] (P=0.001), and 12 hours of life [287.1 (16.4-769.1) vs. 66.2 (8.8-757.8) pg/mL] (P<0.05). Significant higher IL-6 levels greater than 200 pg/mL were observed at 3 hours (P=0.005) and at 12 hours of life (P=0.023) for poor prognosis group. CONCLUSION: There was a significant correlation between neurologic outcome and plasma IL-6 levels. Higher concentrations of IL-6 (>200 pg/mL) may be a useful indicator of poor neurological outcome in infants with severe fetal distress.

PURPOSE: To evaluate the association between multidrug resistance (MDR) gene and prognosis of acute lymphoblastic leukemia (ALL), several parameters were compared according to the expression status of MDR associated P-glycoprotein. METHODS: 40 bone marrow samples from 36 children of acute lymphoblastic leukemia were analyzed with immunohistochemical stain by C219 monoclonal antibody. RESULTS: 1) The expression of MDR associated P-glycoprotein was positive in 47% at the time of initial diagnosis & 66.7% at relapse. 2) There are no stastical difference between two groups in complete remission rate, relapse rate, mean 2 years survival rate. 3) Event free survival duration was 11.3 months (+/-8.5 months) in P-glycoprotein positive group, while 20 months (+/-7.3months) in P-glycoprotein negative group (P<0.05). 4) There are no stastical difference between two groups in the mean age, sex ratio, initial WBC and immunophenotype of subjects. CONCLUSION: These results suggested the possibility of adopting MDR associated P-glycoprotein in the design of therapeutic regimen and prognostification of childhood acute lymphoblastic leukemia. However, a prospective, randomized study incorporating a larger population should precede before a firm conclusion of significance would draw regarding the prognostic and the therapeutic implication of P-glycoprotein in childhood acute lymphoblastic leukemia.

Lymphangioma of the large bowel is a rare benign tumor which is composed of numerous small or large thin-walled lymphatie spaces contained fibrous tissue, smooth muscle and aggregates of lymphoid tissue. Lymphangioma never demonstrated any potential for malignant degeneration. There are three types; l. simple capillary lymphangioma, 2 cavernous lymphangioma and 3 cystic lymphangioma. Endoscopically, lymphangioma appears as a compressible smooth, round, or oval submucosal tumor covered with pale intact mucosa. The surfaces is smooth and the superficial color is the same as the surrouding mucosa or slightly more yellowish. There are change of dimension and shape during propagation of the peristaltic wave and on compression. Recently, authors experienced 4 cases of lymphangioma of large intestine which has been revealed by typical colonoscopic findings and/or endoscopic ultrasound, and confirmed by surgical resection and colonscopic snare polypectomy. 3 of 4 cases show cystic lymphangioma and one case shows carvenous lymphangio~rna. We report these cases with review of literatures.

BACKGROUND/AIMS: Viral breakthrough has been considered a major limitation of lamivudine in the treatment of hepatitis B virus related chronic liver disease. Its clinical meaning has not been thoroughly assessed. METHODS: 64 patients who showed viral breakthrough during lamivudine treatment were retrospectively reviewed. We evaluated the rate of HBeAg seroconversion and hepatic decompensation after viral breakthrough. RESULTS: After viral breakthrough, serum alanine transaminase (ALT) elevation more than 1.2X upper limit of normal (ULN) was noticed in 40 patients (62.5%). Acute flare (serum ALT elevation >X5 ULN, or serum bilirubin >3 mg/dL) occured in 15 patients (23.4%). During the period of follow up (15.0 +/- 9.7 months; range, 0-31 months) since viral breakthrough, decreased serum HBV-DNA level to below the detection limit and serum ALT normalization was seen in 15 patients (23.4%). HBeAg seroconversion was noticed in 7 (13.7%) of a total of 51 HBeAg positive patients at base line; in 4 (15.4%) of 26 patients with non-hepatic failure (chronic hepatitis or Child-Pugh class A liver cirrhosis) at base line; and in 2 (40.0%) of 5 patients with non-hepatic failure at base line and acute flare after viral breakthrough. During this period, terminal hepatic decompensation (Child-Pugh class C) or death was noticed in 9 (90.0%) of 10 patients who had hepatic decompensation (Child-Pugh class B or C) at baseline and acute flare after viral breakthrough. CONCLUSIONS: Acute flare after viral breakthrough seemed to continue during HBeAg seroconversion and rarely developed into terminal hepatic decompensation or death in patients with non-hepatic decompensation at baseline. Its incidence is not only high but lethal to most patients with hepatic decompensation at baseline.

Right atrial metastasis occurs in 1 to 4% of patients with hepatoma. and the extention to intracavitary or metastasis of tumor as a large mass rare. However, the high risk of progressive heart failure and sudden death from the tricuspid valve obstruction necessitates prompt diagnosis of intracavitary extension, and adequate intervention is needed to prolong a patient's life. A 49 year-old female was referred to our hospital for further evaluation of a liver mass, which was identified at a local clinic. The liver mass was confirmed as hepatocellular carcinoma with CT and celiac angiographic finding. She was treated with transarterial chemoembolization. Thirty-four months after discharge, a low density right atrial mass was noted incidentally with chest computed tomography while investigating massive right pleural effusion for possible pulmonary metastasis. Echocardiography showed a huge inhomogenous echogenic mass at the right atrium. The present report describes a case of primary hepatocellular carcinoma with a intracavitary cardiac mass detected with two dimensional echocardiography.

Vertebroplasty (VP) is a well-known therapeutic modality used to treat pain associated with vertebral compression fractures. Major complications such as cord or root compression, epidural and subdural hematomas (SDH) and pulmonary emboli, occur in less than 1% of patients who undergo VP after compression fracture. Spinal SDH is an extremely rare complication that usually happens a few hours after the procedure. We report a case of spinal SDH that developed at two weeks after a successful VP. We also reviewed related literatures and discussed its possible pathogenesis.

PURPOSE: Endoscopic transnasal correction of the blowout fractures has many advantages over other techniques. But after removal of packing material, there were some patients with recurrence of preoperative symptoms. Authors tried to make a quantitative anterograde analysis of orbital volume change over whole perioperative period which might be related with recurrence of preoperative symptoms. METHODS: 10 patients with pure medial wall fracture(Group I) and 10 patients with medial wall fracture combined with fracture of orbital floor(Group II) were selected to evaluate the final orbital volume change with 3 CT scans, preoperatively, postoperatively and 4 months after packing removal. By multiplying cross-section area of orbit in coronal view with section thickness, orbital volume were calculated. Then, mean orbital volume increment after trauma, mean orbital volume decrement after endoscopic correction and volume increment after packing removal were found out. And we tried to find correlations between type of fracture, initial correction rate and final correction rate. RESULTS: The mean orbital volume increase of the fractured orbits were 7.23% in group I and 13.69% in group II. After endoscopic surgery, mean orbital volume decrease were 11.0% in group I and 12.46% in group II. Mean volume increase after packing removal showed 3.10% in group I and 6.50% in group II. The initial correction rate(%) showed linear correlation with final correction rate(%) after packing removal. And there were negative linear correlation between increment percentage of orbital volume by fracture and final correction rate(%). CONCLUSION: Orbital volume was proved to be increasing after removal of packing or foley catheter and it was dependent upon type of fracture. Overcorrection should be done to improve the final result of orbital blowout fracture especially when severe fracture is present.
