The color change of maxillofacial silicone has been attributed to certain environmental factors such as exposure to the UV component of natural sunlight, wetting and drying of the elastomer, and surface abrasion resulting from the application and removal of cosmetics. The purpose of this study was to evaluate the color change of maxillofacial silicone (Silastic MDX4-4210) according to type of pigment (cadmium yellow, titanium white, cosmetic red), and UV absorber application method after 200, 400, and 600 hours of 350nm UV light irradiation. The results were as follows. 1. According to type of pigments, after 200 hours cosmetic red showed significantly larger color change than cadmium yellow and titanium white, and after 400 and 600 hours color change significantly decreased in the order of cosmetic red, cadmium yellow, and titanium white (p<0.05). 2. In the cadmium yellow group, after 200 hours, the non-treatment group showed significantly larger color change, but after 400 and 600hours, color change significantly decreased in the order of non-treatment, surface application and mixed group (p<0.05). 3. In the titanium white group, there was no significant color change difference between the three groups after 200 and 400 hours, but after 600 hours, the mixed group showed significantly smaller color change than the non-treatment and surface application groups (p<0.05). 4. In the cosmetic red group, there was significant decrease in color change in the order non-treatment, surface application and mixed group (p<0.05). From the results above, the effect of UV light absorber differed according to the type of pigment, but mixing UV light aborber with maxillofacial silicone is thought to give superior resistance against UV light irradiation in the long run.

Diaphyseal fractures of the radius and ulna present high incidence of malunion and non-union because of difficulty in reduction and maintenance of two mobile, parallel bones in the presence of the pronating and supinating muscles which exert angulatory as well as rotational forces. Over the years various methods of open reduction and internal fixation or the closed method have been advocated, but open reduction, especially fixation with compression plate and screws resulted in more satisfactory results was proved recently by the major clinical reports. From March. 1977 to December. 1985, 59 cases of diaphysesl fractures of the forearm both bone in adult and children were managed in the Department of Orthopedic Surgery, Chonbuk National University Hospital and comparisions have been made between the conservative treatment group and operative group. The obtained results were as follows; 1. The most common csuse of injury was fallen on the outstretched hand in children and traffic accident in adult. 2. The most frequent site of the fracture was middle one-third(50.8%). 3. The most common pattern of the fracture was stable fracture(50.1%). 4. The applied methods for management of the fractures include cast immobilization after manual reduction or skeletal traction, K-wire fixation, compression plate and screws, intramedullary nailing, and combined. 5. Comparision of conservative treated group with operative treated group was as follows. 1) In roentgenologically, excluding those complicated by nonunion or infection, average bone union time of conservative group in children and adolescence was 10.2 weeks and in adult was 16.7 weeks, and of operative group was 13.9 weeks. 2) According to Grace and Eversmann's evaluation, Satisfactory results were shown in 80.0% of children and adolescence group treated by conservative method and 86.7% of adult group trested by compression plate and screws. 3) Among the various internal fixstion methods, compression plate and screws method was the best measure for rapid bone union and functional recovery in adult. 4) Any marked difference between each group was not seen in nonunion, but angulstory and rotational deformity were more common in conservative group and infection was developed 2 cases in operative group only. 6. There was no noticesble difference between each treatment in children and adolescence, but operative treatment, especially compression plate and screws, in adult was more superior to conservative treatment with. regard to bone union time and functional result.

PURPOSE: This descriptive research study aims to investigate influential factors on human papillomavirus vaccines, among parents who have elementary school daughters. METHODS: This study was conducted with 210 parents whose children are elementary school girls, aged 9 to 12 years, in G Metropolitan City. Data were collected from August 17 to September 12, 2015 using structured questionnaires. A descriptive statistical analysis, a t-test, a χ2-test, a Fisher's exact test, and a logistic regression using SPSS/WIN 21.0. RESULTS: The influential factors on the human papillomavirus vaccination intention were confirmed to be three variables: cervical cancer knowledge, perceived sensitivity, and perceived barriers. CONCLUSION: An intervention program, both to increase the sensitivity of vaccination and to decrease barriers, should be developed so as to improve parents' health beliefs towards human papillomavirus vaccination.

PURPOSE: To investigate the clinical effects of a single high dose intravenous immunoglobulin (IVIG) combined with initial dexamethasone as a primary treatment on Kawasaki disease (KD). MATERIALS AND METHODS: Between January 2008 and December 2010, we reviewed the medical records of 216 patients with complete KD patients that were admitted to a single medical center. 106 patients were treated with a single high dose of IVIG (2 g/kg) alone and 110 patients received IVIG and dexamethasone (0.3 mg/kg per day for three days). RESULTS: The combined IVIG plus dexamethasone patient group had a significantly shorter febrile period and duration of hospital stay (1.4+/-0.7 days vs. 2.0+/-1.2 days, p<0.001; 5.8+/-1.7 days vs. 6.9+/-2.5 days, p<0.001, respectively) than the IVIG alone group. The combined IVIG plus dexamethasone group required IVIG retreatment significantly less than the IVIG only group (12.7% vs. 32%, p=0.003). After completion of the initial IVIG, C-reactive protein levels in the combined IVIG plus dexamethasone group were significantly lower than those in the IVIG only group (2.7+/-4.0 mg/dL vs. 4.6+/-8.7 mg/dL, p=0.03). In the combined IVIG plus dexamethasone group, the incidence of coronary artery lesions tended to be lower without worse outcomes at admission after initial infusion of IVIG and in follow-up at two months; however, the differences were not significant (8.2% vs. 11.3%, p=0.22; 0.9% vs. 2.8%, p=0.29). CONCLUSION: Initial combined therapy with dexamethasone and a single high-dose of IVIG resulted in an improved clinical course, in particular a shorter febrile period, less IVIG retreatment, and shorter hospital stay without worse coronary outcomes.

PURPOSE: This study was performed to elucidate the clinical pictures of acute focal bacterial nephritis(nephronia) in children. METHODS: We reviewed 9 children with nephronia diagnosed by ultrasonography or computed tomography of kidneys from September 1994 to August 2004. RESULTS: The overall male to female ratio was 2:1, and the age distribution ranged from 0.1 to 6 years(mean 2.8+/-2.2). The cardinal symptoms were fever, chills, abdominal pain and dysuria/frequency. The initial leukocyte count was 21,000+/-5,600/uL; ESR, 60+/-23 mm/hr; CRP, 17+/-10 mg/dl. Pyuria was noted in every patient and persisted for 10.5+/-7.8 days after antimicrobial treatment. Abdominal sonography demonstrated focal lesion of ill-defined margin and low echogenicity in 5 of 9 patients(55.6%), while computed tomography revealed nonenhancing low density area in all patients(100%). Three of 9 patients(33.3%) had vesicoureteral reflux, greater than grade III. The initial (99m)Tc-DMSA scan showed one or multiple cortical defects in every patient, and improvements were noted in 2(33.3%) of 6 patients who received follow up scan after 4 months. Intravenous antibiotics was given in every patient under admission. Total febrile period was 11.8+/-6.3 days(pre-admission, 4.0+/-3.0; post-admission, 7.8+/-5.5 days) and the patients needed hospitalization for 17.2+/-8.1 days. CONCLUSION: For the early diagnosis of 'acute focal bacterial nephritis' we should perform renal computed tomography first rather than ultrasonography, when the child has toxic symptoms and severe inflammatory responses in blood and urine.

BACKGROUND: The use of ambulatory blood pressure monitoring (ABPM) in childhood hypertension has been in great advance. ABPM has been able to detect significantly high blood pressure (BP) and also helpful for identifying white coat hypertension. METHODS: Between March 2007 and December 2009, we evaluated individuals aged from 7 to 19 years who were referred as high BP with ABPM, echocardiogram, and abdominal computerized tomography, calculation of body mass index (BMI) at Ajou University Hospital. ABPM was performed using the Tonoport V monitors and SpaceLab 90217 monitors. Seventy were evaluated with 55 boys and 5 girls. The mean age of them was 13.1 +/- 2.8 years (mean +/- standard deviation). RESULTS: Forty of seventy (57.1%) were diagnosed as hypertension in ABPM and 8 of 40 were diagnosed as secondary hypertension with underline diseases such as hyperthyroidism, chronic renal disease, Takayasu's arteritis, coarctation of aorta. The mean BMI in 40 was 24.8 +/- 4.72 kg/m2. Twenty-three of seventy (32.8%) were obese with higher prevalence than in general population. White coat hypertension was diagnosed in 30 of 70 (42.9%). CONCLUSIONS: ABPM could provide more detailed data including mean values of BP, load, and night dip in assessment of children's BP. According to increasing children's obesity, use of ABPM was thought to be necessary for evaluation of their risk of hypertension and useful for diagnosis of masked hypertension and white coat hypertension. Further more study of ABPM in children and adolescents would be needed for absolute standards of ABPM.

Interscalene bracheal plexus block has became a popular method of anesthesia for surgical operation on the upper extremities. Possible complications are subarachnoid block, epidural block, phrenic nerve block, vagus or recurrent laryngeal nerve block, sympathetic nerve block, intravascular injection. But reported complications has been few and generally without prolonged effects. The following describes a patient who developed signs and symptoms suggestive of inadvertent phrenic nerve block and epidural anesthesia as complications of interscalene bracheal plexus block The complications were attributed to using of inferomedially directed 5 cm needle and then additional blind block of the brachial plexus with 5 or 6 times. We emphasize that if the appropriate length of needle and technique are not used, phrenic nerve paralysis and serious complications including total spinal or epidural block can occur as a result of a medially misdirected needle.

The effects of intravenous Verapamil administration on ventricular function were evaluated using grated radionuclide ventriculography in 15 patients with essential hypertension. Verapamil(0.1mg/kg) was injected as a bolus for 2 minutes followed by an infusion of 0.007mg/kg/min. Heart rate, blood pressure, ejection fraction, peak ejection rate, total filling time, and prak filling rate were assessed before and after Verapamil administration. The results were was as follows ; 1) Verapamil administration increased heart rate from 63+/-5 to 75+/-9 beats/min(p<0.01) and reduced systolic and diastolic blood pressure from 156+/-17/99+/-6mmHg to 139+/-16/88+/-6mmHg(p<0.01). 2) Ejection fraction, peak ejection rate, and total filling time were not changed significantly after Verapamil injection. 3) Right and left ventricular peak filling rate increased significantly only in patients in whom it was subnormal in the basal study) from 1.6+/-0.4 to 2.3+/-1.1 end-diastolic volumes/s, p<0.05 and from 2.5+/-0.6 to 3.1+/-0.8 end-diastolic volumes/s, p<0.05, respectively). In conclusion, it was found that intravenous Verapamil administration enhances ventricular diatolic function in patients with essential hypertension.
