PURPOSE: This study was performed to evaluate the efficiency of Platelet-rich plasma (PRP) for acceleration of bone healing process on allograft transplantation after curettage in benign bone tumor. MATERIALS AND METHODS: From December 2007 to February 2009, twenty-one patients who had benign bone tumor and underwent allograft transplantation after curettage were evaluated. Mean follow-up period was 14.6 months (range, 12-26 months). We compared with 13 cases of PRP group and 8 cases of non-PRP group in terms of size of lesion, bone resorption, amount of applied PRP and complications. The mean age at surgery was 23.6 years (range, 4-73 years). The most common diagnosis was simple bone cyst (7) followed by enchondroma (4), giant cell tumor (3), undifferentiated benign bone tumor (3) and so on. RESULTS: The mean size of lesion was 33.5 cm3 (range, 2.3-181.9 cm3) (29.4 cm3 in PRP group and 40.2 cm3 in non-PRP group). The mean volume of injected PRP was 7.4 cc (range, 3-12 cc). Bone union started at 3.0 months (range, 1.5-5.8 months) in PRP group and 5.3 months (range, 4-8 months) in non-PRP group. Three cases for each group were excluded due to recurrence and pathologic fracture. One patient had febrile episode 3 weeks later after surgery which subsided with antibiotics. CONCLUSION: The PRP could accelerate bone union in allograft transplantation after curettage of benign bone tumor. Furthermore, we expect that PRP can accelerate bone union in fracture or non-union.

Acrodermatitis enteropathica(AE) which starts in early infancy after weaning is a rare hereditary chronic disorder of zinc absorption. AE is characterized by alopecia, diarrhea and skin lesions localized to periorificial areas and acrally on the extremities. However, recent reports presented Transient Symptomatic Zinc Deficiency(TSZD) in preterm infants. TSZD is clinically similar to AE and skin lesions rapidly heals after zinc supplementation. When the treatment was withheld, no recurrence was seen. We experienced a TSZD case in a cow's milk fed, preterm infant, so We report it with a brief review of literature.

Department of Rehabilitation Medicine, Seoul National University Hospital, Seoul, KoreaCarbamazepine (CBZ) is the common antiepileptic drug prescribed for the management of neuropathic pain in patients with neurologic injury. CBZ can rarely be the causative agent to result in drug-induced hypersensitivity syndrome (DIHS), which is a life-threatening drug reaction. Delayed diagnosis of DIHS may occur in complicated clinical settings. We have reported a case of a 12-year-old girl whose initial manifestations of CBZ-induced DIHS were atypical due to concurrent administration of corticosteroids. After open biopsy of brainstem glioma, she was administered corticosteroids and CBZ to mitigate postoperative complications, including mild weakness of ankle dorsiflexion and otalgia. Not only fever but also elevation of liver enzymes and inflammatory markers were presented 1 month after CBZ initiation, without any skin rash or leukocytosis. A maculopapular rash on the whole body and leukocytosis developed afterward; consequently, the diagnostic criteria for DIHS were fulfilled. After discontinuation of CBZ, her fever and increased liver enzymes subsided and the rash slowly improved. This case indicates that typical signs, such as skin rash or leukocytosis, can be initially masked or delayed in CBZ-induced DIHS if it overlaps with corticosteroid administration. The atypical manifestations of DIHS should be considered if CBZ is concurrently administered with corticosteroids.

Purpose: : This study aimed to verify the effectiveness of the clinical ladder system (CLS) by identifying the perception of the CLS, professional self-concept, self-efficacy, and organizational commitment among intensive care unit (ICU) nurses. Methods: : Data were collected through a questionnaire survey of 173 nurses working in 11 ICUs at a tertiary hospital in Seoul. Results: : The perception of the CLS, self-efficacy, and organizational commitment showed significant difference according to the CLS level. As a result of the partial Spearman correlation analysis after adjusting for demographic difference according to CLS (age, marital status, education, and clinical career), CLS positively correlated with the perception of the CLS (r=.16, p=.045), professional self-concept (r=.24, p=.001), and self-efficacy (r=.21, p=.007). On the contrary, organizational commitment negatively correlated with the perception of the CLS (r=-.43, p＜.001) and self-efficacy (r=-.32, p＜.001). Conclusion : The CLS is effective for professional self-concept and self-efficacy. However, specialists 2 nurses, who had high professional self-concept and self-efficacy, showed low level of organizational commitment. Thus, it is necessary to examine the factors of work burden and career plateau that are imposed after promotion and improve experience and planning according to the growth needs. Moreover, regular evaluation of the CLS will require hospital support to ensure that ICU nurses appreciate and actively participate in the support.

PURPOSE: The aim of this study was to examine the relationship between tooth loss and sub-clinical atherosclerosis in Korean adults. MATERIALS AND METHODS: The subjects were part of a cohort study conducted in Ansan city by the Korea University medical school as part of the Korean Genome project. 749 subjects over than 40 years old were evaluated. After taking panoramic radiography, the amount of tooth loss was calculated. The intima-media thickness (IMT) was assessed by using ultrasonography at the common carotid artery. Traditional cardiovascular risk factors for atherosclerosis were also evaluated. The relationship between tooth loss and the IMT was evaluated using ANOVA with Scheffe's multiple comparison method in univariate analysis. Multiple regression analysis was also performed to determine the significance between the IMT and tooth loss. RESULTS: With age, tooth loss increased, but there was no significant increase in other traditional cardiovascular risk factors. Univariate analysis revealed the IMT to be positively related with the amount of tooth loss. Regression analysis of the IMT in the anterior and posterior tooth loss revealed that only the posterior tooth loss was significantly related with the IMT at all sites of the common carotid artery (right far wall, P = .015; left far wall, P = .008; right near wall, P < .001; left near wall, P = .001). CONCLUSION: This study verified the positive relationship between the increased tooth loss at the posterior area and the accumulation of atheroma in arteries.

PURPOSE: Atopic dermatitis (AD) is a chronic inflammatory skin disorder with a association of genetic, environmental, and immunologic factors in the development of AD. And AD can be classified into IgE mediated and non-IgE mediated. We investigated a difference of clinical characteristics and immune response between the two groups. METHODS: From January 2008 to December 2011, we enrolled 125 children who visited Dong-A University Medical Center and Busan Medical Center, and were diagnosed as AD with the Haniffin and Rajka's criteria. We checked the history of combined asthma and allergic rhinitis and allergic disease of family in patients. We measured serum total IgE, specific IgE by ImmunoCAP or skin prick test. We measured serum interleukin (IL) 4 (IL-4), interferon-gamma (IFN-gamma), IL-10, and IL-17, which are associated with chronic inflammatory disorder by flow cytometry method (Luminex). RESULTS: Eighty (64%) were included in the IgE mediated group, while forty-five (36%) were included in the non-IgE mediated group. The frequency of combined allergic disorder and serum total eosinophil count were relatively higher in IgE mediated group (P=0.023, P=0.032). The incidence of a family history in allergic disease and the mean of SCORing Atopic Dermatitis index had no difference between the two groups. Serum IL-4, IFN-gamma, IL-10, IL-17 were higher in the IgE mediated group, but there were no statistically significant differences between two groups (P>0.05). CONCLUSION: IgE mediated AD showed higher total eosinophil count and higher incidence of bronchial asthma and allergic rhinitis than non IgE mediated AD.

BACKGROUND: Liver transplantation (LT) is a complicated procedure with a high incidence of postoperative acute kidney injury (AKI). Previous studies indicate that even transient or mild post-LT AKI can result in critical conditions, including prolonged stays in hospitals and intensive care units and increased morbidity and mortality. The aim of this study was to investigate the association between body mass index (BMI) and occurrence of AKI in LT recipients. METHODS: Medical data from 203 patients who received LT surgery from January 2010 to August 2016 in a single university hospital setting were retrospectively collected and analyzed. Patients were classified as either underweight (BMI <20 kg/m²) or normal weight (20 ≤ BMI < 30 kg/m²). Demographic data, anesthetic methods, complications, and perioperative laboratory test values of each patient were assessed. Propensity analyses and logistic regression were performed to evaluate the association between BMI and post-LT AKI. RESULTS: There was no significant difference in occurrence of post-LT AKI between underweight and normal weight patients. The underweight patient group had significantly longer hospital stay compared with the normal weight patient group (P = 0.023). CONCLUSIONS: BMI classification was neither a positive nor negative predictor of postoperative AKI occurrence. However, patients with lower BMI had significantly longer hospital stay compared with their counterparts. Although our study was limited by its retrospective design, our observations suggest that lower BMI might play a role in post-LT AKI.

BACKGROUND/OBJECTIVES: Oxidative stress is a major effector of various diseases; accordingly, antioxidants are frequently ingested in order to prevent or alleviate disease symptoms. Kimchi contains various natural antioxidants, and it is known that the functional activity varies depending on the ingredients and fermentation state. Black raspberries (BR) contain various bioactive compounds with antioxidant effects. This study investigated the antioxidant and liver-protection effects of kimchi supplemented with black raspberry juice powder (BJP). MATERIALS/METHODS: BJP-added kimchi (BAK; at 0.5%, 1%, and 2% concentrations of BJP) and control (without BJP) were prepared and fermented at 4℃ for 4 weeks. Changes in the antioxidant effects of BAK during fermentation were investigated. In addition, the protective activity of BAK against oxidative stress was investigated in a liver cirrhosis-induced animal model in vivo. RESULTS: BAK groups showed the acidity and pH of optimally ripened (OR) kimchi at 2 weeks of fermentation along with the highest lactic acid bacterial counts. Additionally, BAK groups displayed a higher content of phenolic compounds and elevated antioxidant activities relative to the control, with the highest antioxidant effect observed at 2 weeks of fermentation of OR 1% BAK. After feeding the OR 1% BAK to thioacetamide-induced liver cirrhosis rats, we observed decreased glutamate oxaloacetate transaminase and glutamate pyruvate transaminase activities and elevated superoxide dismutase activity. CONCLUSIONS: These findings showed that the antioxidant effects of OR BAK and feeding of OR 1% BAK resulted in liver-protective effects against oxidative stress.

PURPOSE: This study was conducted to explore the nursing needs and satisfaction of patients who are hospitalized at hospice palliative care institutions. METHODS: This study included 80 hospice patients who were in-patients of the hospice department of two general hospitals in S city. The collected data were analyzed by descriptive statistics, t-test, one-way ANOVA, and Pearson's correlation coefficients using the IBM SPSS 20.0 program. RESULTS: The mean score of nursing needs and satisfaction were 3.58 (+/-0.31) and 3.25 (+/-0.20) respectively. Significant differences in hospice nursing needs and satisfaction were observed in terms of general characteristics including gender, education level, occupation, religion, support for medical expense and functional status. Significant positive correlation was found between the overall nursing needs and nursing satisfaction. CONCLUSION: Based on the results of this study, in order to improve the quality of hospice service, further study is necessary in a comprehensive manner to develop nursing intervention to meet physical, psychological/social, spiritual, and educational/referral nursing needs of hospice in-patients.
