The purpose of this study is to evaluate the flow ability of the thermoplasticized Gutta Percha in different temperatures. Four Gutta Percha products were classified by its hardness (soft, medium, and hard) and were experimented by the Rheometer (Melt flow indexer MFI-10, DAVENPORT, England) measuring apparatus, in (23 ± 2) ℃, and in a relative humidity of (50 ± 5) %, following the guidelines of ISO 1133-1:2011. The heating temperature ranged from 108℃, 160℃ to 200℃, and the load at 2.16 kg and 3.8 kg. The Gutta Percha was cut in 5 mm to be suitable for the rheometer pressurization process. After the experiment was conducted with a preheating time of 5 minutes, a cutting time of 5–240 seconds, and a sample of 10 grams, the Gutta Percha did not show any changes in fluidity for 108℃, 160℃, but showed a change in its flow ability in 200℃. Also, the Gutta Percha did not show any changes in its fluidity when it was pressurized by 2.16 and 3.8 kilograms. Therefore, this experiment shows that the heating temperature and the cut-off time showed a significance while measuring the melt flow rate.

Purpose:
Food sensitization to egg white (EW) peaks during early childhood, after which some children with sensitization to EW outgrow food sensitization, while others develop an increased degree of sensitization to EW. We investigated factors determining changes in EW-specific IgE in children under 2 years of age.
Methods:
Among children under 2 years of age with atopic dermatitis or food allergy who visited Asan Medical Center from March 2018 to September 2021, a total of 172 sensitized to EW were enrolled. Serum specific IgE to EW, ovalbumin and ovomucoid, and specific IgG4 to EW and ovomucoid were measured at 0, 6, and 12 months. An increase in EW-specific IgE was defined as an increased level of EW-specific IgE after 12 months from baseline. Multiple logistic regression analysis was performed to identify factors determining an increase in EW-specific IgE.
Results:
Of the 172 children, 85 had complete data on serum specific IgE and specific IgG4 during a period of 12 months. The levels of EW-specific IgE were decreased in 51 subjects (60.0%), while they were increased in 34 subjects (40.0%). Introduction of baked eggs had a protective effect against an increase in EW-specific IgE levels during a period of 12 months (adjusted odds ratio, 0.148; 95% confidence interval, 0.022–0.983).
Conclusion
Introduction of the baked egg can prevent an increase in EW-specific IgE during early childhood. Further studies are needed for the long-term effect of baked egg on the natural course of EW sensitization.

OBJECTIVE: To evaluate the effects of piroxicam patch(Trast) in rheumatoid arthritis patients with knee joint pain and swelling and to determine the concentration of plasma and synovial fluid following patch application. METHODS: Twenty-two patients with rheumatoid arthritis participated in a double-blind, placebo-controlled study. The patients were instructed to apply piroxicam or placebo patch at one knee and re-apply it every other day for 2 weeks. They had washout period for 2 weeks and then applied the other patch for 2 weeks at the same joint. The patients recorded knee joint pain using visual analog scale. Knee joint swelling and tenderness were assessed before and after application of piroxicam and placebo patch. Complete blood count, AST, ALT, BUN, creatinine, joint fluid analysis were also done. Piroxicam concentration in plasma and synovial fluid were measured by high performance liquid chromatography(HPLC) after 2 weeks of piroxicam patch application. RESULTS: Knee joint pain improved significantly after the application of piroxicam patch for 2 weeks(visual analog scale, 56. 2+5. 9m vs 48. 2+5. 7mm, p=0. 03 by Wilcoxon signed rank test). There was no significant change in white cell count of synovial fluid, peripheral blood cell count, chemistry, C-reactive protein and erythrocyte sedimentation rate. In terms of adverse effects, mild gastrointesti nal disturbance(8/21 cases, 38%) and local side effects such as pruritus and ery thema(3/21 cases, 14%) were developed, which were insignificant compared with control groups(30%, 15% respectively). Piroxicam concentrations in plasma and synovial fluid after the application of piroxicam patch were 0. 129+0. 04ug/ ml (mean+SE) and 0. 644+0. 202ug/ml respectively. CONCLUSIONS: Piroxicam patch is a safe and effective therapeutic modality for knee joint pain in patients with rheumatoid arthritis. Mild adverse effects such as gastrointestinal disturbance and local side effects were noted. Piroxicam concentration was higher in synovial fluid than in plasma following the application of piroxicam patch.

OBJECTIVES: Paranoia is a complex phenomenon, affected by a number of factors such as depression, trait anxiety, and attributional bias in schizophrenia. The aim of this study was to explore whether paranoia within continuum of clinical and subclinical states is associated with emotional dysregulation, attributional bias and neurocognitive impairment in whole individuals of normal controls, ultra-high risk (UHR) for psychosis and schizophrenia. METHODS: 101 normal controls, 50 participants at UHR for psychosis, and 49 schizophrenia patients were recruited. All subjects were asked to complete self-reported paranoia scale and emotional dysregulation scales including Rosenberg's self-esteem, Spielberg's state-trait anxiety inventory and Beck depression inventory. The attributional style was assessed by Ambiguous Intentions Hostility Questionnaire (AIHQ). Participants were also requested to complete the comprehensive neurocognitive battery. RESULTS: Multiple linear regression analysis showed that paranoia were found to be associated with emotional dysregulation (state anxiety, trait anxiety and depression), composite blaming bias in ambiguous situation, impairment of attention and working memory in whole participants [F (9, 190)=34.85, p<0.001, adjusted R2=0.61]. CONCLUSION: The main findings suggest that paranoia is a complex affective and cognitive structure that may be associated with emotional dysregulation, blaming bias and attention and working memory impairment in clinical and non-clinical paranoia.

BACKGROUND/OBJECTIVES: We examined dietary fat intake and the major food sources by young children in Korea. SUBJECTS/METHODS: A total of 1,041 children aged 1–5 years were identified from the 2013–2015 Korea National Health and Nutrition Examination Survey. Data on total fat and fatty acid intake were obtained by a single 24-h dietary recall. Food sources were identified based on the amounts of total fat and fatty acids consumption according to each food. Fat and fatty acid intakes and their food sources were presented by age group (1–2-y, n = 401; 3–5-y, n = 640). Fat and fatty acid intakes were also evaluated according to socioeconomic characteristics. RESULTS: The mean intake of fat was 27.1 ± 0.8 g in the 1-2-y group and 35.5 ± 0.7 g in the 3-5-y group, and about 23% of the total energy was obtained from fat in both age groups. The mean intake of saturated fatty acids (SFA) was 10.5 ± 0.3 g in the 1-2-y group and 12.7 ± 0.3 g in the 3-5-y group, with the 1-2-y group obtaining more energy from SFA than the 3-5-y group (9.2% vs. 8.3%). The mean intake of polyunsaturated fatty acids (PUFA) was 6.3 ± 0.1 g in the total subjects, with 0.8 ± 0.03 g of n-3 fatty acids and 5.5 ± 0.1 g of n-6 fatty acids being consumed. Milk, pork, and eggs were major food sources of total fat, SFA, and monounsaturated fatty acids, and soybean oil was the main contributor to PUFA in both age groups. In the 1-2-y group, children in rural areas had significantly higher intake of PUFA and n-3 fatty acids than did those in urban areas. CONCLUSIONS: Our findings provide current information on dietary fat intake among young Korean children and could be used to establish dietary strategies for improvement of health status.

Purpose:
This study evaluated the clinical effects of heated humidified high flow nasal cannula (HHHFNC) treatment in pediatric patients with respiratory disease and respiratory insufficiency.
Methods:
We reviewed the medical records for clinical features and tests performed in patients admitted to Chungnam University Hospital pediatric ward and treated with HHHFNC between July 2014 and December 2018. We evaluated the effects of HHHFNC treatment in patients with bronchiolitis treated with oxygen using a nasal prong.
Results:
The 136 children were treated with HHHFNC during the study period, and their median age was 8 months. Among the 136 patients, 39 (28.7%) were diagnosed with bronchiolitis and pneumonia, 42 (30.9%) with pneumonia, 28 (20.6%) with bronchiolitis, and 3 (2.2%) with epilepsy. Thirty-five patients (25.7%) had underlying neurological disorders. Fifty-one (37.5%) received invasive ventilator treatment. After HHHFNC treatment, venous blood gas analysis showed a pH increase from 7.32 to 7.37 (P<0.05) and a decrease in partial pressure of carbon dioxide (pCO2) from 53.1 to 46.2 mmHg (P<0.05). The respiratory rate had decreased from 46.3 to 43.3/min (P<0.05). There were no statistically significant differences in hospital stay duration or intensive care unit admission rates between bronchiolitis patients receiving HHHFNC treatment and those not receiving.
Conclusion
In this study, in various diseases leading to pediatric respiratory insufficiency, HHHFNC treatment may improve physiologic parameters at the pediatric ward. HHHFNC may also be effective in patients with underlying neurological disorders and those with respiratory insufficiency from nonrespiratory infectious disease.

Journal of Korean Medical Science 2020;35(38):e337-
Background:
A national immunization program (NIP) to prevent disease and reduce mortality from vaccine preventable diseases (VPD) is very important.
Methods:
We analyzed only the anaphylaxis cases that occurred between 2001 and 2016 that Korea Centers for Disease Control and Prevention (KCDC) determined had a definite causal relationship with a vaccine. The clinical symptoms were assessed according to the Brighton Collaboration case definition (BCCD) level.
Results:
During the period, there were 13 cases of vaccine-related anaphylaxis. The median age was 9 years (range, 1 month to 59 years). The incidence of anaphylaxis per million doses was 0.090 in 2005, 0.079 in 2012, 0.071 in 2013, 0.188 in 2015, and 0.036 in 2016. Of those cases, 23.1% were influenza vaccines, and 76.9% were BCCD level 2. Epinephrine was used in 46.2%.
Conclusion
Vaccine-related anaphylaxis seems to have been very rare in the past, but health care professionals must always be aware of anaphylaxis.
