The prevalence of chronic diseases have been rising in the developing countries because of their increased animal foods consumption and Western lifestyle. Lately, vegetarian diet that exclude animal products get public attention. The purpose of this study was to evaluate the nutritional status and dietary quality of vegetarians, and their consumption of vitamin K and was also assessed. Vegetarians including strict vegan and lacto-ovo-vegetarian consumed their diet at least over 6 months. Carnivores were gender and age matched with vegetarians and they consumed over 50% of protein and fat from animal sources. Current nutrient intakes and dietary quality were assessed using 3-day food records and intake of vitamin K was calculated from the data base of "Provisional Table on the vitamin K contents of foods, USA". Blood sample were collected and biochemical parameters and plasma phylloquinone concentrations were analyzed. Anthropometric data from vegetarian and carnivore were not significantly different. The intake of calories, protein, vitamin B2, Ca and Zn of the vegetarians were remarkably lower than RDA for each nutrient. Moreover, index of nutritional quality and nutrient adequacy ratio of vegetarians were lower than those of carnivore. Vegetarian consumed less fat and the ratio of n-6/n-3 fatty acid was lower in vegetarian. The intake of essential amino acids in vegetarian was significantly lower than that of carnivore. The vitamin K consumption and plasma phylloquinone concentration of vegetarian were significantly higher than those of carnivore (p < 0.05). The dietary vitamin K consumption was positively correlated with plasma phylloquinone levels in vegetarian (p < 0.01).

PURPOSE: The purpose of this study was to investigate the effect of the development and application of the new nurses' core skill program on the clinical skill, confidence, knowledge and performance of new nurses. METHODS: This study was a nonequivalent control group post-test design on 46 new nurses with 3 to 6 months work experience in a general hospital. Data were collected from August 2015 to August 2016. A training program of core fundamental nursing skills was applied on 23 new nurses from 2016 in the experiment group, and an existing training method was applied on 23 new nurses from 2015 in the comparison group. The collected data were analyzed using SPSS/WIN 23.0. RESULTS: The experimental group (89±4.29) showed higher score in practical skill assessment compared to the control group (85.09±3.99) and showed a statistically significant difference (p<001). CONCLUSION: A training program of core fundamental nursing skills for new nurses proved effective in improving practical skills. Further research on the development of a systemic training program that can improve clinical nursing knowledge and work ability for new nurses according to the extended enforcement of a Nursing Care Integrated Service ward is needed.

BACKGROUND: This study compared the incidence of emergence agitation and the recovery profile from sevoflurane anesthesia after thiopental sodium, propofol or ketamine induction in pediatric inguinal herniorrhaphy. METHODS: Forty eight children aged 1-7 years undergoing high ligation due to an inguinal hernia were examined. All patients received a 0.004 mg/kg glycopyrrolate injection for premedication prior to induction and were randomly assigned to receive thiopental sodium 5 mg/kg (Group T, n = 16), propofol 2 mg/kg (Group P, n = 16) or ketamine 1 mg/kg (Group K, n = 16) for induction. The side effects during the induction time were checked. All patients received sevoflurane (2-2.5 vol%)-N2O (2 L/min)-O2 (2 L/min) for the maintenance of anesthesia. Ventilation was given to assist spontaneous ventilation using a facial mask. The agitation score, pain score, discharge score, incidence of emergence agitation and postoperative side effects in the three groups were assessed at the recovery room and compared. RESULTS: The emergence time in Group T (7.5 +/- 1.8 min) was significantly rapid. The agitation and pain scores were significantly low in Group P. The discharge score was more rapid in Groups P and K than in Group T. The incidence of emergence agitation was similar in all three groups. CONCLUSIONS: Although recovery was faster and emergence agitation was low in the propofol group, propofol induction was not smooth compared with thiopental or ketamine induction. The incidence of emergence agitation after sevoflurane anesthesia in pediatric inguinal herniorrhaphy was similar in the thiopental sodium, propofol or ketamine induction groups.

Overnight fasting before elective surgery has been the routine to reduce the risk of pulmonary aspiration. Recently, several international guidelines for preoperative fasting recommend to intake carbohydrate-containing fluids up to 2 to 3 hours before the induction of anesthesia to improve postoperative recovery. Based on the recommendations, we developed a "preoperative carbohydrate diet" provided for the preoperative patients. The purpose of this case report is to share our experience of applying preoperative carbohydrate loading prior to surgery.

BACKGROUND: Neurosurgical site infection may have serious sequelae, especially that occurring after craniotomy. A nationwide prospective multicenter study was performed in Korea to determine the incidence and risk factors for surgical site infections (SSI) after craniotomy. Methods: We collected demographic data, clinical and operative risk factors for SSI, and information regarding the antibiotics administered for the patients who underwent craniotomy in 17 hospitals between July and December of 2008. All the data were collected using a real-time web-based reporting system. RESULTS: Of the 1,020 patients who underwent craniotomy, 31 (3%) developed SSI, including 4 with superficial incisional SSI, 2 with deep incisional SSI, and 25 with organ/space SSI. The SSI rate was predicted on the basis of the National Nosocomial Infections Surveillance (NNIS) risk index. The SSI rate of 3.1%, 3.3%, and 1.8% were ascribed NNIS scores of 0, 1, and 2, respectively. The independent risk factors for SSI identified were postoperative cerebrospinal fluid leakage (odds ratio, 12.13; 95% confidence interval, 4.54-32.42) and preoperative Glasgow coma scales score < or =8 (odds ratio, 2.35; 95% confidence interval, 1.07-5.18). Third generation cephalosporins were the most frequently (in 65.6% of the cases) used for prophylaxis. CONCLUSION: A multicenter SSI surveillance system for craniotomy was first established in Korea. The NNIS risk index was not effective in identifying the patients at risk. We required to further analyze a large number of SSI cases to correctly identify the risk factors for SSI after craniotomy.

The followings are the results for external quality assessment (EQA) in immunoserology for 2003: 1.Evaluation of EQA was done in 2 trials in May and November, about 99% of laboratories participating average 8.2 items. 2.In C-reactive protein (CRP), rheumatoid factor (RF) and anti-streptolysin O (ASO) tests, about 63%, 49% and 44% of the participating laboratories respectively have used quantitative assays. Because the laboratories using quanitiative assays were on the increase annually, commercial control, Liquicheck(TM) Immunology Contol from Bio-Rad Laboratories (Irvine, CA, USA) was used to assure the quality of quantitiavie results in 2003. A few laboratories reproted the outlier results, comparing with the reference ranges presented by the company. 3.Over 92% of participating laboratoreis have used imunoassays including enzyme immunoassay (EIA), microparticle EIA (MEIA), chemiluminescence immunoassay (CIA), immunochromatography assay (ICA) or radioimmunoassay (RIA) for detedting viral antigens or antibodies. Especially for anti-HCV, over 98% of participating laboratoreis have used various kind of imunoassays. Laboratories using ICA increased and about 24% of participating laboratoreis have used ICA for anti-HCV and anti-HIV. However, many laboratories using ICA for detecting anti-HCV reported false negative results, suggesting lower sensitivity of ICA than those of other immunoassays. 4.The criteria of interpretation were considered to be evaluated in Widal test and laboratories using ICA increased in serological tests for syphilis.

The followings are the results for external quality assessment (EQA) in immunoserology for 2004: 1. Evaluation of EQA was done in 2 trials in May and November, about 99% of laboratories participating average 8.4 items. EQA for anti-HBc test was newly started in 2004. 2. Commercial control, MASR Immunology Control from Medical Analysis Systems (Camarillo, CA, USA) was used to assure the quality of quantitative results of C-reactive protein (CRP), rheumatoid factor (RF) and anti-streptolysin O (ASO) tests in 2004. All the specimens for Immunoserology in EQA were delivered refrigerated for the first time, being received within 48 hours after sending. 3. EQA for detection of HBsAg mutants was tried for the first time, using the recombinant HBsAg mutant (Gly/Arg 145) kindly provided by Abbott Laboratories, USA. 4. The laboratories using immunochromatography assay (ICA) were increased, however, many laboratories using ICA reported falsely negative for the positive specimens. The sensitivity of ICA test kits as well as various factors influencing the ICA results should be evaluated. 5. Standardization of methods including calibrators for quantitative results should be required for the harmonization of results.

The followings are the results for external quality assessment (EQA) in immunoserology for 2002: 1. Evaluation of EQA was done in 2 trials in May and November, about 96% of laboratories participating average 8.3 items. 2. In C-reactive protein (CRP), rheumatoid factor (RF) and anti-streptolysin O (ASO) tests, about 40%, 53% and 52% of the participating laboratories respectively have used qualitative assays, mainly latex agglutination. And about 55%, 43% and 40% of the participating laboratories have used quantitative assays, turbidimetric immunoassay (TIA) or nephelometry in CRP, RF and ASO tests respectively. Laboratories using TIA increased and those using nephelometry decreased. The instruments which were the most frequently used in nephelometry were BN series (Dade Behring Inc., Germany). The instruments of Hitachi series (Hitachi Ltd., Japan), Cobas Integra and Mira series (Roche Diagnostics GmbH, Germany), Toshiba series (Toshiba Corporation, Japan) and Olympus AU series (Olympus Optical Co., Ltd., Japan) were frequently used in TIA. The quantitative results were quite variable according to the methods or reagents, especially in RF and ASO. 3. Over 90% of participating laboratoreis have used imunoassay including enzyme immunoassay (EIA), microparticle EIA (MEIA), chemiluminescence immunoassay (CIA), immunochromatography assay (ICA) or radioimmunoassay (RIA). Laboratories using CIA and ICA increased. Sensitivities of ICA were lower than those of other immunoassays in the results of HBsAg and anti-HCV. The sensitivity of SD HCV (Standard Diagnostics, Inc., Korea) was especially lower in anti-HCV results. Sensitivities of CIA and ICA were also lower than those of EIA including MEIA in the results of anti-HIV. 4. The criteria of interpretation were considered to be evaluated in Widal test and laboratories using ICA increased in serological tests for syphilis.

BACKGROUND: Data on the clinicopathologic features of hair follicle tumors in Korea are limited. OBJECTIVE: The purpose was to investigate the clinical and histopathologic characteristics of hair follicle tumors in Korea. METHODS: Two hundred sixty four cases of hair follicle tumors seen from 1999 to 2001 in Korea were analyzed clinically and histopathologically. RESULTS AND CONCLUSION: The most common hair follicle tumor in Korea was pilomatricoma(81.0%), followed by trichoepithelioma(6.4%), dilated pore of Winer(3.8%), and proliferating trichilemmal tumor(2.2%). Hair follicle tumors usually occurred as a solitary skin-colored nodule. The most commonly involved site was the face, and the peak age of presentation was 10 to 19. Pilomatricoma usually occurred as a solitary skin-colored nodule. The most commonly involved site was the arm, and more than 50% of tumors occurred before the age of 20. Histopathologically, the tumor was often surrounded by fibrous capsule and was composed of basophilic and shadow cells. It was usually located in the dermis and extended into the subcutis. Retraction spaces between tumor nests and stroma were frequently observed. Trichoepithelioma usually occurred as multiple skin-colored papules on the face. Histopathologically, the tumor was usually located in the dermis with sometimes connected to the epidermis. It frequently showed peripheral palisading. Dilated pore of Winer usually occurred as a solitary brownish to pigmented papule on the face in middle-aged persons. Proliferating trichilemmal tumor occurred as a solitary or multiple tumors. Histopathologically, the tumor was usually surrounded by incomplete fibrous capsule. Tumor cells frequently showed clear cell formation, nuclear atypia, mitosis, peripheral palisading, trichilemmal keratinization, and individual keratinization.
