Neuropathic shoulder arthropathy or Charcot's shoulder is an extremely rare disease, and sometimes it is associated with cervical syringomyelia. Clinical symptoms of the disease include edema of the shoulder and restriction in range of motion. Radiological diagnosis can be made through plain radiography through a characteristic, atrophic destruction of the joint. We experienced a Charcot's joint of the shoulder wherein destruction of the joint progressed extremely quickly and reviewed the literature concerning this condition.

PURPOSES: The purposes of this study were to examine knowledge related to child abuse, attitudes toward child abuse, and intention to report child abuse and to identify the predictors of nurses' intention to report child abuse. METHOD: A descriptive-correlational study was conducted. Participants were 171 nurses who worked in the pediatric or emergency rooms in G city. Self-administered questionnaire was used for data collection. Descriptive statistics, t-test or ANOVA, Pearson correlation, and stepwise multiple regression analysis were used for data analysis. RESULTS: Nurses had a limited knowledge related to child abuse. Nurses had negative attitudes toward child discipline, were inclined to punish the abuser, and had positive attitudes about professional responsibility for reporting child abuse. Nurses perceived difficulty in the actual behavior of reporting child abuse. Nurses' intention to report child abuse was predicted by nurses' attitudes to professional responsibility for reporting child abuse. CONCLUSIONS: Based on the findings of this study, educational programs need to be developed, implemented, and evaluated. The conclusion of this study is that supplementary education is needed for multidisciplinary decision making concerning the role of the nurses within the context of child abuse.Implications for nursing practice, education and research are discussed.

PURPOSE: The prevalence of urinary incontinence (UI) among community-dwelling older women in Korea is not well known. This study examined the prevalence of UI and UI-related knowledge among community-dwelling Korean women aged 55 and over. METHOD: A cross-sectional descriptive-correlational study was conducted. Data were collected from 276 women aged 55 and over in a metropolitan city using a structured questionnaire. RESULT: Of 276 respondents, 28.3% (n = 78) reported experiencing UI. More than 50% of respondents incorrectly agreed with the statement that UI is the result of normal aging, with only 20.9% realizing that there is an exercise that can control urine leaks when one coughs, sneezes, or laughs. Older women who had sought treatment had higher mean score for UI-related knowledge. CONCLUSION: This study revealed substantial misconception about UI among community dwelling older women, demonstrating that comprehensive educational programs need to be developed to increase knowledge of UI.

PURPOSE: Disturbances of mineral metabolism are common during the course of chronic kidney disease (CKD) and may lead to serious and debilitating complications unless properly treated. The purpose of this study is to quantify the prevalence of secondary hyperparathyroidism and vitamin D deficiency in non-dialysed chronic kidney disease 3, 4, and 5 in Korea. METHODS: This study included patients who had documented eGFR<60 mL/min/1.73m2 and non-dialysed and had not received any vitamin D compounds. eGFR was calculated by simplified MDRD (Modification of Diet in Renal Disease study) equation. Blood samples were collected for serum creatinine, calcium, phosphate, intact PTH and vitamin D metabolites between May 2006 and April 2007. RESULTS: According to K/DOQI guideline, the prevalence of hyperparathyroidism was 46.9% (15/32) in stage 3 (iPTH>70 pg/mL),45.9% (17/37) in stage 4 (iPTH>110 pg/mL) and 20.5% (9/44) in stage 5 patients (iPTH>300 pg/mL). The prevalence of 25-hydroxyvitamin D deficiency (25(OH)D3<15 ng/mL) was 86.2% (25/29) in stage 3, 75.7% (28/37) in stage 4 and 88.4% (38/43) in stage 5. There was a negative correlation between eGFR and intact PTH (r=-0.531, p=0.000) and a positive correlation between eGFR and 1,25-dihydroxyvitamin D (r=0.587, p=0.000). Conclusions: So far as non-dialysed CKD patients in Korea are concerned, quantification of the prevalence of abnormality of intact PTH and vitamin D deficiency has been described in this study. More research should be conducted in the future in a prospective, multi-center community cohort study, of which subjects include the early stages like CKD 1 and 2.

PURPOSE: The purpose of this study was to evaluate the effects of the Spirituality Promotion Program(SPP) for young nurses working in the stressful university hospital environment. METHODS: The study included 41 nurses in the experimental group, nurses who had worked less than 5 years and completed 8 weeks of SPP between June and July in 2011. The control group, 44 nurses, also received the same program after the study was completed. For the study, a survey was conducted of all participants concerning spirituality, perceived stress, positive and negative affect, empathy, job satisfaction, and leadership practice. RESULTS: No significant difference was found between the two groups on study variables. Perceived stress decreased significantly in the experimental group (p=.012). Spirituality (p=.019), positive affect (p=.014), empathy (p=.004), job satisfaction (p=.016), and leadership practice (p=.021) increased significantly in the experimental group. CONCLUSION: The results show that the Spirituality Promotion Program has positive effects on the spiritual and psychosocial aspect of young nurses. Continuation of this program for nurses is recommended in order to help them develop their selfcare ability and improve nursing competency.

Background: Papillary thyroid carcinoma (PTC) can be classified into two distinct molecular subtypes, BRAF-like (BL) and RASlike (RL). However, the molecular characteristics of each subtype according to clinicopathological factors have not yet been determined. We aimed to investigate the gene signatures and tumor microenvironment according to clinicopathological factors, and to identify the mechanism of progression in BL-PTCs and RL-PTCs. Methods: We analyzed RNA sequencing data and corresponding clinicopathological information of 503 patients with PTC from The Cancer Genome Atlas database. We performed differentially expressed gene (DEG), Gene Ontology, and molecular pathway enrichment analyses according to clinicopathological factors in each molecular subtype. EcoTyper and CIBERSORTx were used to deconvolve the tumor cell types and their surrounding microenvironment. Results: Even for the same clinicopathological factors, overlapping DEGs between the two molecular subtypes were uncommon, indicating that BL-PTCs and RL-PTCs have different progression mechanisms. Genes related to the extracellular matrix were commonly upregulated in BL-PTCs with aggressive clinicopathological factors, such as old age (≥55 years), presence of extrathyroidal extension, lymph node metastasis, advanced tumor-node-metastasis (TNM) stage, and high metastasis-age-completeness of resection- invasion-size (MACIS) scores (≥6). Furthermore, in the deconvolution analysis of tumor microenvironment, cancer-associated fibroblasts were significantly enriched. In contrast, in RL-PTCs, downregulation of immune response and immunoglobulin-related genes was significantly associated with aggressive characteristics, even after adjusting for thyroiditis status. Conclusion The molecular phenotypes of cancer progression differed between BL-PTC and RL-PTC. In particular, extracellular matrix and cancer-associated fibroblasts, which constitute the tumor microenvironment, would play an important role in the progression of BL-PTC that accounts for the majority of advanced PTCs.

Purpose: Occupational exposure to pesticides is thought to be associated with lung cancer, but studies have yielded conflicting results. We performed a propensity score (PS) based analyses to evaluate the relationship between occupational exposure to pesticides and lung cancer risk in the Korea National Cancer Center community-based cohort study (KNCCCS). Materials and Methods: During the follow-up period, 123 incidental lung cancer cases were identified, of the 7,471 subjects in the final statistical analysis. Information about occupational exposure to pesticides and other factors was collected at enrollment (2003-2010). Cox proportional hazards regression analyses were conducted. Four PS-based approaches (i.e., matching, stratification, inverse probability-of-treatment weighting, and the use of the PS as a covariate) were adopted, and the results were compared. PS was obtained from the logistic regression model. Absolute standardized differences according to occupational exposure to pesticides were provided to evaluate the balance in baseline characteristics. Results: In the Cox proportional hazards regression model, the hazard ratio (HR) for lung cancer according to occupational exposure to pesticides was 1.82 (95% confidence interval [CI], 1.11 to 2.98). With all the propensity score matching (PSM) methods, the HRs for lung cancer based on exposure to pesticides ranged from 1.65 (95% CI, 1.04 to 2.64) (continuous term with PSM) to 2.84 (95% CI, 1.81 to 4.46) (stratification by 5 strata of the PS). The results varied slightly based on the method used, but the direction and statistical significance remained the same. Conclusion Our results strengthen the evidence for an association between occupational exposure to pesticides and the risk of lung cancer.

PURPOSE: Direct sequencing (DS) is the standard method for detection of epidermal growth factor receptor (EGFR) gene mutation in non-small cell lung cancer (NSCLC); however, low detection sensitivity is a problem. The aim of this study is to demonstrate higher detection rate of EGFR gene mutation with peptide nucleic acid (PNA) clamping compared with DS. MATERIALS AND METHODS: This is a single arm, prospective study for patients with stage IIIB/IV or relapsed NSCLC. Using tumor DNA from 138 patients, both DS and PNA clamping for EGFR gene in exon 18, 19, 20, and 21 were performed. Discrepant results between the two methods were verified using Cobas and a mutant enrichment based next generation sequencing (NGS). Patients with activating mutations were treated with EGFR tyrosine kinase inhibitor (EGFR-TKI, gefitinib, or erlotinib) as first line treatment. RESULTS: Of 138 paired test sets, 24 (17.4%) and 45 (32.6%) cases with activating mutations were detected by DS and PNA clamping, respectively. The difference of detection rate between the two methods was 15.2% (95% confidence interval, 8.7% to 17.8%; p < 0.001). Between the two methods, 25 cases showed discrepant results (n=23, PNA+/DS-; n=2, PNA-/DS+). Mutations were confirmed by Cobas or NGS in 22 of 23 PNA+/DS- cases. The response rates to EGFR-TKI were 72.2% in the PNA+/DS+ group and 85.0% in the PNA+/DS- group. CONCLUSION: PNA clamping showed a significantly higher detection rate of EGFR gene mutation compared with DS. Higher sensitivity of PNA clamping was not compromised by the loss of predictive power of response to EGFR-TKI.

PURPOSE: Neoadjuvant chemotherapy (NC) is yet to be established as the definitive treatment regimen for locally advanced breast cancer (LABC). The aim of this study was to determine the efficacy and toxicity of NC with epirubicin and paclitaxel. METHODS: Between March 2007 and January 2009, 50 patients with LABC were enrolled in an open-label, phase II, multicenter study carried out at five distinct institutions. All patients were scheduled to receive four cycles of 60 mg/m2 epirubicin and 175 mg/m2 paclitaxel every 3 weeks, preoperatively, unless they developed profound side effects or disease progression. After curative surgery, two additional cycles of chemotherapy were administered to patients who had shown a positive response to NC. RESULTS: In all, 196 cycles of chemotherapy were administered preoperatively; 47 of the 50 patients (94%) underwent all four cycles of designated treatment. Complete disappearance of invasive foci of the primary tumor, and negative axillary lymph nodes were confirmed in eight patients (16.0%), post operation. The cumulative 5-year disease-free survival rate was 70.0% for patients with complete remission (CR) and partial remission (PR), and 33.3% for patients with stable disease (SD) and progressive disease (PD) (p=0.018). The cumulative 5-year overall survival was 90.0% for patients who achieved CR and PR and 55.6% for patients who had SD and PD (p=0.001). Neutropenia (42.0%) was the most common grade 3/4 toxicity. However, none of the toxicities resulted in cessation of the treatment. CONCLUSION: The encouraging pathologic response observed in the patients treated with epirubicin plus paclitaxel NC in this study suggests that epirubicin could be a substitute for doxorubicin, which is the most cardiotoxic agent.
