PURPOSE: Ventriculoperitoneal (VP) shunt insertion is an important treatment modality in children with hydrocephalus. VP shunt infection is a major complication and an important factor that determines the surgery outcome. This 15-year study was performed to evaluate the epidemiology of VP shunt infections in pediatric patients treated at our center. METHODS: A retrospective review of medical records was performed in patients 18 years old or younger who underwent VP shunt insertion surgery from April 1995 to June 2010. RESULTS: Three hundred twenty-seven VP shunt surgeries were performed in a total of 190 pediatric patients (83 females, 107 males). The median age of the patients was 2.4 years (range, 0.02-17.9 years). Having a malignant brain tumor was the most frequent cause for VP shunt insertion. The shunt infection rate was 6.7% (22/327) per 100 operations and 9.5% (18/190) per 100 patients, and the incidence rate was 0.45 infection cases per 100 shunt operations-year. The most common pathogen was coagulase-negative staphylococcus (n=7) followed by methicillin resistant Staphylococcus aureus (n=1). Ten cases were treated with vancomycin and beta-lactam antibiotic (cephalosporin or carbapenem) combination therapy and 7 cases were treated with vancomycin monotherapy. The median duration of antibiotic treatment was 26 days (range, 7 to 58 days). Surgical intervention was performed in 18 cases (18/22, 81.8%). CONCLUSION: Epidemiologic information regarding VP shunt infections in pediatric patients is valuable that will help guide proper antibiotic management. Additional studies on the risk factors for developing VP shunt infections are also warranted.

The aim of this study was to investigate what is the most accurate and quick temperature measurement among rectal, auxiliary and tympanic routes. The body temperatures of 86 preterm infants in incubators, a controlled environment, were measured at three different sites. The measurements were taken to examine the accuracy of the temperatures, proper nursing time for measuring the temperatures and the validity of fever detection. The results were as follows : 1. The mean temperature was significantly lower in the auxiliary site(36.71degrees C) and higher in the tympanic site(37.27degrees C) than in the rectal site(37.03degrees C). 2. The mean nursing time for measuring body temperature was significantly longer in the auxiliary site(171.65 seconds) and shorter in the tympanic site(17.70 seconds) than in the rectal site(83.33 seconds). 3. The nursing time for measuring body temperature included the time needed for preparation, measuring, as well as the post-measuring time. It was found that the time required to prepare for measuring the temperature of the rectal site was significantly longer than for other sites. In addition, the time needed to measure the temperature of the auxiliary site was significantly longer than in the other sites. Finally, the nursing time needed for measuring the auxiliary temperature(171.65 seconds) was the longest among the three sites whereas the nursing time for the tympanic site was the shortest(17.70 seconds). 4. Rectal temperature was significantly correlated to the tympanic(r=0.67) and auxiliary temperatures(r=0.69). Tympanic temperature was also significantly correlated to the auxiliary temperature(r=0.74). 5. The sensitivity, specificity, positive and negative predictive values of tympanic temperatures for detecting fever were 1.00, 0.80, 0.24, and 1.00, respectively. Those for the auxiliary temperatures were 0.00, 0.99, 0.00, and 0.94, respectively. Thus the level of fever detection was lower in the auxiliary temperatures than in tympanic temperatures. The above findings indicate that the tympanic method of temperature measurement offers a useful alternative to conventional methods.

BACKGROUND: The studies about that hypertension commonly associated with dyslipidemia and that dyslipidemic hypertension increased mortality compared with hypertension only and dyslipidemia only, suggests an important clinical entity. Therefore, this study aimed to identify prevalence and describe potential insulin resistance of dyslipidemic hypertension, and compare about them with two other groups(dyslipidemia only, hypertension only). METHODS: The data in this study was analyzed from 1,296 persons who had visited Health examination center in Ewha Womans University Mok-dong Hospital from Jan. to April, 1996. Prevalence of dylipidemia, hypertension and dislipidemic hypertension were measured. Average age, and frequency of male, obesity and NIDDM in three groups were measured. Odds ratios of sex, obesity, smoking, and DM according to two age group consisting of persons before and after 50 years were calculated for three groups. RESULTS: Frequency of dyslipidemia only was 27% and of hypertension only was 8%.; conjoint frequency(dyslipidemic hypertension) was 7%, which is 1.5 times greater than expected value(4.7%) if the two diseases were independent. In characteristics for age, sex, obesity and NIDDM, All three groups(dyslipidemic hypertension, dyslipidemia only, hypertension only) w-normal subjects. Dyslipidemic hypertension was more likely to be obese and had a greater frequency of NIDDM than two other group(dyslipidemia only, hypertension only). Odds ratio was contrasted with three groups for sex, smoking, obesity, NIDDM stratified by age to more indentify association with insulin resistance. Sex was associated with male in two groups(dyslipidemia only, dyslipidemic hypertension) of younger group and dyslipudemia only group of older group, but associated with female in hypertension only and dyslipidemic hypertension of older group. Smoking was associated with dyslipidemia only group of younger group. Obesity was associated with increased odds of dyslipidemia only(2.03) and hypertension only(2.02), dyslipidemic hypertension (4.38) in younger group, and dyslipidemic hypertension(2.24) in older group, but associated with decreased odds with dyslipidemia only(0.56). NIDDM was associated with increased odds of dyslipidemia only(2.39) and dyslipidemic hypertension(3.32) in youger group. CONCLUSIONS: Dyslipidemic hypertension is common and more often than would be dictated by chance alone, which is consistent with a distinct syndrome. Dyslipidemia and hypertension were associated with potential insulin resistant states of obesity and DM in this study. So, treatment of dislipidemic hypertension should focus on weight control and exercise, which increase insulin sensitivity.

OBJECTIVE: This study was performed to investigate the effects of external tooth bleaching with flouridation on the appearance of white spot lesions (WSLs) in vitro. METHODS: In total, 125 bracket-bonded bovine incisor enamel blocks with artificial WSLs were randomly divided into a control group and four treatment groups (home bleaching, home bleaching + fluoridation, in-office bleaching, and in-office bleaching + fluoridation). A spectroradiometer (SR) and digital images (DIs) were used to evaluate colorimetric parameters (Commission Internationale l'Eclairage L*a*b*) for all specimens. Color measurements were obtained before WSL formation (T1), after WSL formation (T2), and after completion of the external tooth bleaching treatment (T3). RESULTS: The SR-based color change after bleaching was significantly greater in the treatment groups than in the control group (p < 0.05). SR-based lightness (L*) and red-green (a*) values were significantly higher at T2 than at T1 (p < 0.001), with no significant changes in yellow-blue (b*) values. At T3, SR-based L* values had increased while a* and b* values had decreased in the treatment groups (p < 0.001). The DI-based color difference between the sound enamel and WSL areas (ΔE*DI) increased significantly from T1 to T2 in all groups (p < 0.001) and significantly decreased from T2 to T3 in the treatment groups (p < 0.001). No significant differences in ΔE*DI at T3 were shown between the four treatment groups (p > 0.05). CONCLUSIONS: The findings of this study suggested that external tooth bleaching with fluoridation can alleviate the conspicuity of WSLs.

Objective: To investigate remineralizing effect of three fluoride regimens on artificially demineralized enamel around orthodontic bracket by analyzing mineral density (MD) acquired from micro-computed tomography (micro-CT). Methods: Forty-eight bracket bonded bovine incisors were prepared to create demineralized enamel (DE) surface. The samples were divided into four groups according to the fluoride regimen: 1) no fluoridation, 2) 1.23% acidulated phosphate fluoride (APF) gel, 3) fluoridated toothpaste, and 4) 0.05% sodium fluoride mouthwash. Micro-CT was scanned after demineralization (T0), and 2 weeks (T1) and 4 weeks (T2) of fluoridation. Results: APF gel showed highest remineralization of DE during T1–T0 interval among the groups (p < 0.05); followed by toothpaste, mouthwash and no fluoridation. APF gel and toothpaste demonstrated significant increase in MD after 4 weeks of application (p < 0.05). Conclusions Remineralization effects of three fluoride regimens were depicted through micro-CT analysis, of which APF gel was most effective.

The aims of this study were to clarify the topography and variations stylopharyngeus (STP) and superior constrictor (SC) muscles, and to examine what role they play in the pharyngeal movement. Forty-four specimens (22 right and 22 left sides) from embalmed Korean adult cadavers (13 males, 9 females; age range, 46–89 years; mean age, 69.2 years) were used in this study. The accessory bundle of STP and petropharyngeus was found in 18.2% (8/44) and 25.0% (11/44) of cases, respectively. A variation of the STP, in which it ran transversely and merged with the SC muscle, was found in 2.3% (1/44) of cases while a variation of the SC muscle, in which it ran longitudinally and merged with the contralateral constrictors, was found in 11.4% (5/44). The variant muscle bundles play their own role in pharyngeal movement according to their morphology. These results provide information that will help a comprehensive understanding of the effects of pharyngeal muscles on movement.

PURPOSE: Varicella Zoster Immune Globulin (VZIG) is available in Korea for post-exposure prophylaxis of the Varicella-zoster virus (VZV) in high-risk patients. In July 2013, the United States Centers for Disease Control and Prevention (US CDC) recommended extending the time for administration of VariZIG(R) from within 96 hours up to 10 days after VZV exposure. This study was performed to analyze the effectiveness of VZIG prophylaxis between the two groups of patients who received VZIG within 96 hours and more than 96 hours of exposure to varicella. METHODS: A retrospective chart review was performed in pediatric patients who received VZIG at Samsung Medical Center, Seoul, Korea from January 2001 to December 2012. RESULTS: A total of 91 patients were identified. Fifty-seven patients were male (62.6%) and the median age was 5.91 years. Thirty-nine patients (42.9%) were exposed to VZV in the hospital. Underlying diseases were solid tumors (41.8%), hematologic malignancies (40.7%), and others (17.5%). Forty-five patients (49.5%) were hematopoietic cell transplant recipients. Seventy-four patients (81.3%) received VZIG within 96 hours after VZV exposure. There was no significant difference in the development of chickenpox between the two groups (2.7% vs. 5.9%, P=0.4664). In 22 seronegative patients, we also observed no significant difference between the groups in terms of the development of chickenpox (6.6% vs. 0%, P=0.667). CONCLUSIONS: This study showed that the effectiveness of VZIG for the prevention of chickenpox was comparable between patients who received VZIG within 96 hours and those who received VZIG more than 96 hours after exposure to VZV.

OBJECTIVE: The purpose of this study was to evaluate the relation between idiopathic scoliosis and facial deformity in the horizontal, vertical, and anteroposterior planes. METHODS: A total of 123 female patients aged 14 years or older, who visited the Spine Clinic at the Department of Orthopedics, Korea University Guro Hospital for treatment of idiopathic scoliosis, were enrolled. Whole-spine anteroposterior and lateral radiographs were taken with the patient in a naturally erect position, and frontal and lateral cephalograms were taken in an erect position with the Frankfort horizontal line parallel to the floor. Scoliosis was classified according to the Cobb angle and Lenke classification of six curve types. Cephalometric tracing in all cases was carried out with V-Ceph 5.5 by the same orthodontist. The Kruskal-Wallis test was performed to determine whether any relation existed between each group of the idiopathic scoliosis classification and the cephalometric measurements of frontal and lateral cephalograms. RESULTS: The measurements did not reveal any significant association between the Cobb angle and cephalometric measurements and between the curve type based on the Lenke classification and cephalometric measurements. CONCLUSIONS: Based on the results of this study, no apparent relation was observed between the severity of scoliosis and facial form variations in idiopathic scoliosis patients.
