Dyskeratosis congenita is a rare genodermatosis of ectodermal dysplasia, which is characterized by the diagnostic triad consisting of reticulated hyperpigmentation, dystrophic nails, and leukoplakia. There is a predisposition to malignancy, particularly at sites of leukoplakia. Bone marrow failure can occur in about a half of the cases. A 16-year-old boy was presented with asymptomatic reticulated pigmentation of the neck and nail dystrophy. The patient also had leukoplakia on the tongue, nasolacrimal duct obstruction and cataract. The histopathological findings taken from the reticulated lesion were consistent with poikiloderma atrophicans vasculare. These clinical and histopathological findings were typical features of dyskeratosis congenita.

PURPOSE: This study was conducted to analyze industrial workers' stresses from physical symptoms, PWI, JCQ and tasks in classification of Sasang constitutions. METHOD: Data were collected from industrial workers in J Province from May 2003 to June 2003. Questionnaires were distributed and collected on the day of their physical examination. Collected data were analysed through chi2-test. RESULT: Health-related characteristics showed that most of smokers and drinkers were Taeumins and this result was statistically significant. Physical symptoms related to constitutions indicated that GI and neurologic symptoms are significantly more frequent in Soeumin. The percentage of subjects with moderate risk was high in order of Soyangin, Taeumin and Soeumin while the percentage of subjects with high risk was high in order of Soeumin, Taeumin and Soyangin. CONCLUSION: Through this study, Lee Jae Ma's theory was be confirmed compatible with disease characteristics. However, research with more various subjects and variables needs to be made.

PURPOSE: The purpose of this study was to investigate the feasibility of shear wave ultrasound elastography for differentiating superficial benign soft tissue masses through a comparison of their shear moduli. METHODS: We retrospectively analyzed 48 masses from 46 patients from February 2014 to May 2016. Surgical excision, fine-needle aspiration, and clinical findings were used for the differential diagnosis. The ultrasonographic examinations were conducted by a single musculoskeletal radiologist, and the ultrasonographic findings were reviewed by two other radiologists who were blinded to the final diagnosis. Conventional ultrasonographic features and the median shear modulus were evaluated. We compared the median shear moduli of epidermoid cysts, ganglion cysts, and lipomatous tumors using the Kruskal-Wallis test. Additionally, the Mann-Whitney U test was used to compare two distinct groups. RESULTS: Significant differences were found in the median shear moduli of epidermoid cysts, ganglion cysts, and lipomatous tumors (23.7, 5.8, and 9.2 kPa, respectively; P=0.019). Epidermoid cysts showed a greater median shear modulus than ganglion cysts (P=0.014) and lipomatous tumors (P=0.049). CONCLUSION: Shear wave elastography may contribute to the differential diagnosis of superficial benign soft tissue masses through a direct quantitative analysis.

Purpose: This study aimed to examine the effects of the nursing work environment and self-efficacy on medical safety competence of nurses in general hospital. Methods: Participants included 183 nurses who were recruited through convenience sampling in a general hospital in South Korea. Questionnaires were collected from August 25 to September 22, 2023. The nursing work environment, self-efficacy and medical safety competence scales were used to assess the study variables. The t-test, one-way ANOVA, Scheffé ́ test, Pearson correlation coefficients, and multiple regression tests were performed using IBM SPSS ver. 26.0. Results: Statistically significant correlations were found between nurses’ medical safety competence and nursing work environment (r=.34, p<.001), and self-efficacy (r=.48, p<.001). Self-efficacy (β=.38, p<.001), nursing work environment (β=.25, p<.001), and clinical experience (β=.14, p=.043) had the greatest effect on nurses’ medical safety competence (F=21.21, p<.001), with an explanatory power of 30.0%. Conclusion This study confirmed that the nursing work environment and nurses' self-efficacy have a significant impact on nurses' medical safety competence. In order to implement patient safety in hospitals, it is necessary to develop and apply strategies to improve the nursing work environment and increase nurses’ self-efficacy to enhance their medical safety capabilities.

PURPOSE: To evaluate and compare the performance of shear-wave elastography (SWE) for breast masses using the local shear wave speed (m/sec) vs. Young modulus (kPa). METHODS: A total of 130 breast lesions in 123 women who underwent SWE before ultrasound-guided core needle biopsy or surgical excision were included. With the region-of-interest placed over the stiffest areas of the lesion on SWE, the quantitative mean, maximum, and standard deviation (SD) of the elasticity values were measured in kPa and m/sec for each lesion. The SD was also measured with the region-of-interest including the whole breast lesion (wSD). The area under the receiver operating characteristic curve (AUC), sensitivity, and specificity of each elasticity value measured in kPa and m/sec were compared. RESULTS: Of the 130 lesions, 49 (37.7%) were malignant and 81 (62.3%) were benign. The AUCs for the mean, maximum, and SD of the elasticity values using kPa and m/sec did not differ significantly: mean, 0.974 vs. 0.974; maximum, 0.960 vs. 0.976; SD, 0.916 vs. 0.916. However, the AUC for wSD showed a significant difference: 0.964 (kPa) vs. 0.960 (m/sec) (P=0.036). There was no significant difference in the sensitivity and specificity of the mean, maximum, and wSD of the elasticity values. However, the specificity of the SD was significantly different between the two different measurements: 95.1% (kPa) vs. 87.7% (m/sec) (P=0.031). CONCLUSION: The quantitative elasticity values measured in kPa and m/sec on SWE showed good diagnostic performance. The specificity of the SD and AUC of the wSD measured in kPa were significantly higher than those measured in m/sec.

OBJECTIVE: This study was to investigate and develop a training program that integrated and strengthened clinical competence and capacity of hospital pharmacists which would be implemented at the pharmacy department of Ewha Womans University Mokdong Hospital. METHODS: We assessed the training programs of hospital pharmacists in the United Kingdom, the United States and Japan and compared those of major hospitals in Seoul and Gyeonggi provinces in Korea. The survey assessed the satisfaction on the current educational programs for pharmacists at Ewha Womans University Mokdong Hospital and a newly designed education program was suggested. RESULTS: The major differences of the programs among the Korean hospitals and Mokdong Hospital were the training period and contents of the entry-level pharmacist education program. The overall satisfaction of the training program was >3 points on 5-Likert scale in the survey. There was no significant difference of the satisfaction level based on the employment period of pharmacists. The pharmacists were in more than 7 training programs of clinical support work. We proposed the clinical support training for the new pharmacists to be separated from orientation and concentrated on actual work duty. In order to improve the competency, it was encouraged to participate the in-house seminar or certify the related fields provided by Korean Society of Health-system Pharmacists. CONCLUSION: The education program was assessed among different countries and hospitals of Korea. We suggested to update education program in the hospital to enhance pharmacists' competency.

Many chemotherapeutic agents induce both local and systemic cutaneous toxicity. Among them, Fluorouracil (5-FU) induces various cutaneous reaction, including hand-foot syndrome, hypersensitivity, hyperpigmentation and nail changes. We describe a male patient with rectal cancer, who developed combined features of hand-foot syndrome and nail changes during chemotherapy with 5-FU.
