Kawasaki disease (KD) is an immune-mediated disease which is a leading cause of acquired cardiovascular disease in developed country. Recently, tumor necrosis factor-alpha (TNF-alpha) blocker, infliximab has been considered a promising option for patients with refractory KD. Although chronic use of a TNF-alpha blocker could increase risk of opportunistic infections, a few studies have documented that use of infliximab was safe without serious adverse effects in patients with KD. We observed serious bacterial infection after infliximab treatment in an infant with refractory KD. Our patient was a 5-month-old male infant diagnosed with KD who did not respond to repeated doses of intravenous immunoglobulin. We effectively treated him with a single infusion of infliximab (5 mg/kg), but gram-negative (Acinetobacter lwoffii) septicemia developed after infliximab infusion. Therefore, we report a case of serious septicemia after treatment with infliximab, and suggest considering the risk of severe infection when deciding whether to prescribe infliximab to an infant with refractory KD.

BACKGROUND: EMLA cream is a eutectic mixture of lidocaine and prilocaine and has excellent anesthetic effect on tympanic membrane but histologic influence on tympanic membrane is uncertain. OBJECTIVE: To investigate its histologic effects on tympanic membrane. MATERIALS AND METHODS: 18 Sprague-Dawly rats were divided into 6 groups. Each group was treated with application of EMLA cream into external ear canal and then were sacrificed at 4 hours, 24 hours, 3 days, 7 days, and 14 days after application of the agents. RESULTS: 1) Transmission electron microscopy revealed partial loss of epithelial cell at 4 hours after application of the agents. 2) The specimen showed damaged cells in the epidermal layer and partial loss of basement membrane at 24 hours after application of the agents. 3) At 1 week after application of the agents epidermal layer and inner epithelium with connective tissue predominated. Thus the fibrous layer represent only 1/3 of total drum thickness. In the basal layers widened intercellular spaces were noted. 4) At 2 weeks after application of the agents newly formed connective tissue was found at fibrous layer and numerous fibroblasts were noted at inner epithelial layer. but overall histologic changes of the drum were not significant and healing processes was noted. CONCLUSION: EMLA cream has less histopathologic effects on tympanic membrane, and early recovery process occurred.

Experimental & Molecular Medicine 1998;30(1):15-20
DNase I footprinting assay using liver nuclear extracts revealed six protected regions between nucleotide -600 and +110 and hence named Box I-VI. Upstream promoter element (UPE), a DNA element playing crucial role in transcriptional control of the tissue specific expression of pancreatic beta-cell, has been detected within the proximal region of rat GLUT2 promoter. This region is included in Box VI. The protein-DNA interaction in this region (Box VI) was confirmed by mobility shift assay using liver nuclear extracts. Deletion of the region between -585 bp and -146 bp resulted in dramatic changes in promoter activity when they were expressed in liver and beta-cell derived cell line. When -585/-146 construct was expressed in liver, the activity was decreased to 46%, whereas the activity in beta-cell line, HIT-T15 cell, was increased by 84% when compared to -146/+190 construct. These opposing phenomena can be explained by the fact that beta-cell specifically expresses the UPE binding protein. Assuming that there may be Box VI-binding protein playing negative roles both in hepatocyte and beta-cell, and that the protein acts as a negative regulator of GLUT2 gene, the UPE binding protein in the beta-cell may overcome the inhibition by binding to the protein.

PURPOSE: Survivin is a member of the inhibitors of apoptosis family. It has recently comes into the limelight as a promising tumor marker, but many previous reports have shown controversial results regarding the significance and prognostic value of a survivin expression. In this study we determined the correlation between the survivin expression and the conventional prognostic markers and we also investigated the outcomes according to the localization of the survivin expression. METHODS: Tissue microarray (TMA) blocks were made with formalin-fixed paraffin-embedded tissues from 185 breast cancer patients and the immunohistochemical staining was done using an anti-survivin antibody. Among these, 157 patients were available for a survivin expression. The conventional clinicopathologic features and overall survival were correlated with the localization of the survivin expression. RESULTS: Survivin was expressed in 101 breast cancers (64.3%). A higher cytoplasmic survivin expression were noted in the older group (p=0.003), in the node-negative cancers (p=0.012), in the earlier tumor stages (p=0.012) and in the cancers that had not been treated with adjuvant chemotherapy (p=0.014). On the contrary, a higher nuclear survivin expression was inversely correlated with an estrogen expression (p=0.006) and a progesterone receptor (p=0.043) expression. In terms of survival, a cytoplasmic expression was associated with improved overall survival (p=0.01) but a nuclear survivin expression was correlated with unfavorable overall survival (p=0.002). A high cytoplasmic to nuclear ratio of survivin was associated with improved overall survival (p=0.001) conversely, increased nuclear to cytoplasmic survivin ratio was correlated with unfavorable overall survival (p<0.0001). Multivariate analysis revealed that nuclear survivin expression (p=0.001) and high nuclear to cytoplasmic survivin ratio (p=0.012) were independent predictor of overall survival. CONCLUSION: Survivin is frequently expressed in primary breast cancer. A cytoplasmic survivin expression is a good prognostic predictor for patients with axillary node negative early breast cancers and a nuclear survivin expression is a worse independent predictor of overall survival for patients with axillary node positive breast cancers.

BACKGROUND/AIM: There is little data on whether plastic stents with a larger diameter are patent for longer than small stents in patients with bile duct cancer. The aim of this study was to compare the stent survival between 7-French (Fr) and 10-Fr plastic stents and evaluate the factors affecting stent survival. METHODS: Patients with biliary obstruction due to biliary tract cancer were enrolled at Yonsei University Wonju College of Medicine from January 2010 to October 2014. RESULTS: A total of 215 patients (7-Fr:10-Fr = 89:126 patients) were retrospectively enrolled. The primary tumor sites were common bile duct (n = 111), hilar (n = 45), and ampulla of Vater (n = 59). Rates of stent migration and stent obstruction were not different between the two groups. The median duration of stent survival was 3.3 months in the 7-Fr group and 5.9 months in the 10-Fr group (p = 0.543). The diameter of the stent did not have an effect on stent survival (hazard ratio 1.11, 95% confidence interval 0.71-1.73, p = 0.649). CONCLUSIONS: 7-Fr and 10-Fr stents have similar rates of stent migration and stent obstruction. The stent survival of 7-Fr was not inferior to 10-Fr stents in the management of biliary tract cancer.

PURPOSE: High-Sensitivity C-reactive protein(hs-CRP) has been recognized as a very useful and sensitive predictor of the future risk of myocardial infarction. But the clinical significance of hs-CRP in children remains uncertain. To confirm the existence of obesity-induced vascular inflammation and the association between metabolic syndromes and elevation of CRP in children, we investigated the relationship among CRP, obesity, blood pressure(BP), and serum lipids in schoolboys. METHODS: Twenty-eight obese(BMI 29.61+/-3.29 kg/m2) and 93 non-obese(BMI 18.99+/-2.21 kg/m2) boys aged 14 years were examined. Serum CRP levels was measured by the high sensitive latex turbidimetric immunoassay and subjects with CRP levels below 0.3 mg/dL were adopted to avoid the influence of acute infection. RESULTS: Obese children had significantly higher hs-CRP levels than their non-obese group(0.104+/-0.075 vs. 0.054+/-0.005 mg/dL). In the obese group, BMI, systolic blood pressure, diastolic blood pressure, apolipoprotein B, atherogenic index, and triglyceride were significantly higher than in non-obese. The BMI, diastolic blood pressure, apolipoprotein E, atherognic index, and triglyceride showed positive correlation with log CRP by simple regression. Multiple regression analysis indicated that BMI and apolipoprotein E were strongly related to CRP. CONCLUSION: This study revealed that obese children tended to have higher levels of serum hs-CRP, BP elevation and dyslipidemia than the control group and that BMI and apolipoprotein E were strongly related to CRP. These results indicate that obesity related metabolic syndrome can be developed in children.

PURPOSE: The aim of this study was to investigate the pathophysiologic role of serum E-selectin, vascular endothelial growth factor(VEGF)-induced cell adhesion mollecule in Kawasaki disease(KD) and to look for the evidence of direct relationship between the plasma levels of soluble E-selectin and the incidence of coronary artery lesion(CAL). METHODS: Changes in plasma levels of sE-selectin(n=98) over time were measured by enzyme-linked immunosorbent assay(ELISA) in 23 patients with acute KD and 25 age-matched febrile children. RESULTS: Compared with control values, the peak levels of plasma sE-selectin were significantly elevated(mean+/-S.E.:22.89+/-12.53 ng/mL vs 10.65+/-3.42 ng/mL, P=0.01) in KD. 5 patients with CAL, plasma sE-selectin levels before treatment were higher than in 18 patients without CAL(mean+/-S.E.:39.43+/-15.08 ng/mL and 19.00+/-8.32 ng/mL, respectively; P=0.01). Plasma sE-selectin declined rapidly in the majority of KD patients regardless of the presence of CAL. Plasma sE-selectin levels after treatment and convalesent period were similar in KD patients with and without CAL. The plasma levels sE-selectin were correlated with those of white blood cell count(r=0.299, P<0.05), CRP(r=0.430, P<0.05), serum albumin(r=-0.483, P<0.05), serum protein(r=-0.502, P<0.05) and hemoglobin(r=-0.372, P<0.05) not with those of ESR, platelet, or duration of fever. There were significant differences in the initial level of serum sE-selectin between KD with and without CAL(mean+/-S.E.:39.44+/-15.08 ng/mL vs. 19.00+/-17.18 ng/mL) in multivariated linear tests. CONCLUSION: Plasma sE-selectin levels were significantly higher in KD than in other febrile illness. Higher plamsa levels of sE-selectin may have potential as a predictor of CAL in patients with KD.

PURPOSE: X-linked agammaglobulinemia (XLA) is a humoral immunodeficiency disease caused by a mutation in the Bruton tyrosine kinase (BTK) gene resulting in defective B cell differentiation. Because it is a relatively rare disorder, it is difficult for clinicians to have a comprehensive understanding of XLA due to a lack of exposure to the disease. Clinical presentations of patients with XLA were analyzed and discussed to improve care plans. MATERIALS AND METHODS: During a 20 year period, from January 1987 to June 2006, a total of 19 patients were diagnosed as XLA in the Department of Pediatrics at Severance Hospital, Seoul, Korea. A retrospective analysis of the clinical presentations of those patients was performed. RESULTS: The mean age of the XLA patients included in the study was 4.89 years, with a range of 6 months to 13 years. Twelve patients were diagnosed before age 5, while the other 7 patients were diagnosed after age 5. Recurrent infections observed in the patients included pneumonia, acute otitis media, septic arthritis, skin infection, sepsis, sinusitis, acute gastroenteritis, cervical lymphadenitis, epididymitis, meningitis, osteomyelitis, urinary tract infection and encephalitis. Frequency of admissions was variable from 0 to 12 times, depending on the time at which immunoglobulin therapy was started. Six cases had family histories positive for XLA. BTK gene mutations were found in 8 cases. CONCLUSION: The overall prognosis of XLA is good as long as patients are diagnosed and treated early with regular intra venous gamma globulin therapy before the sequelae of recurrent infections appear.

OBJECTIVE: The potassium disturbance associated with thiopental continuous infusion in neurosurgical patients is well known. However, the effect of propofol continuous infusion on serum potassium levels has not been investigated extensively. METHODS: We reviewed the medical records of 60 consecutive patients who received coma therapy or deep sedation for intracranial pressure control using either thiopental or propofol between January 2010 and January 2012. RESULTS: The overall incidence of hypokalemia (K<3.5 mmol/L) was comparable between thiopental and propofol groups (89.2% vs. 82.6%). But, the incidence of moderate to severe hypokalemia (K<3.0 mmol/L) was significantly higher in thiopental group (51.4% vs. 13.0%, p=0.003). The lowest potassium level (2.9 mmol/L vs. 3.2 mmol/L, p=0.020) was lower in thiopental group. The patients in the thiopental group required greater potassium replacement than the propofol group patients (0.08 mmol/kg/h vs. 0.02 mmol/kg/h, p<0.001). On multivariate analysis, thiopental [odds ratio, 95% confidence interval, 7.31 (1.78-27.81); p=0.005] was associated with moderate to severe hypokalemia during continuous infusion. The incidence of rebound hyperkalemia (K>5.0 mmol/L, 32.4% vs. 4.3%, p=0.010) and the peak potassium concentration (4.8 mmol/L vs. 4.2 mmol/L, p=0.037) after the cessation of therapy were higher in thiopental group. On multivariate analysis, thiopental [8.82 (1.00-77.81); p=0.049] and duration of continuous infusion [1.02 (1.00-1.04); p=0.016] were associated with rebound hyperkalemia once therapy was discontinued. CONCLUSION: Propofol was less frequently associated with moderate to severe hypokalemia after induction and rebound hyperkalemia following the cessation of continuous infusion than thiopental.

Focal nodular hyperplasia (FNH) is a benig nepithelial tumor of the liver. The etiology of FNH is unknown, but recent evidence suggests that FNH may represent a localized, hyperplastic response to a pre-existing vascular malformat ion. There is a high probability of as sociat edlesions , most commonly hepatic hemangiomas, meningioma, as trocytoma, and arterial dysplasia in various organs . In the present report we describe a FNH with aberrant lymphatics in a 24-year-old woman. In operation field, lymphatics were located on the site of falciform ligament. Histologically, aberrant lymphatics were composed of well vas cularized complex lymphatic channels and the mass were typical FNH. In this case, the role of aberrant lymphatics in the development of FNH was unclear . But as the FNH frequently as sociated with ot her anomalies , we think the aberrant lymphatic as such anomaly that have not been reported.
