We report a case of solitary congenital calcified nodule of the ear in a 1-year-old female. The lesion was a 2 X 2mm-sized, elevated, slightly erythematous and whitish-centered nodule located since birth on the superior helical rim of her left ear. Histopathological findings fram the totally excised lesion showed calcium deposits as amorphous, basophilic masses in the upper dermis and focal discharge of calcium by means of transepidermal elimination. Surrounding the calcium deposits, lymphohistiocytic infiltrations were present.

Purpose: The purpose of this study was to identify the knowledge structure of health information (HI) for chronic obstructive pulmonary disease (COPD). Methods: Keywords or meaningful morphemes from HI presented on five health-related websites (HRWs) of one national HI institute and four hospitals, as well as HI needs among patients presented in nine literature, were reviewed, refined, and analyzed using text network analysis and their co-occurrence matrix was generated. Two networks of 61 and 35 keywords, respectively, were analyzed for degree, closeness, and betweenness centrality, as well as betweenness community analysis. Results: The most common keywords pertaining to HI on HRWs were lung, inhaler, smoking, dyspnea, and infection, focusing COPD treatment. In contrast, HI needs among patients were lung, medication, support, symptom, and smoking cessation, expanding to disease management. Two common sub-topic groups in HI on HRWs were COPD overview and medication administration, whereas three common sub-topic groups in HI needs among patients in the literature were COPD overview, self-management, and emotional management. Conclusion The knowledge structure of HI on HRWs is medically oriented, while patients need supportive information. Thus, the support system for self-management and emotional management on HRWs must be informed according to the structure of patients’ needs for HI. Healthcare providers should consider presenting COPD patient-centered information on HRWs.

Purpose: : This study aims to identify job stress, emotional intelligence, and exhaustion of the nurses in comprehensive nursing service units and then verify the moderating and mediating effects of emotional intelligence on the relationship between job stress and exhaustion. Methods: : Participants are 118 nurses working in two general hospitals. The collected data are analyzed using the SPSS WIN 27.0 and AMOS 18.0 programs by assessing frequency and percentage, mean and standard deviation, independent t-test and one-way ANOVA, Scheffé test, Pearson correlation coefficient, and hierarchical multiple regression analysis and bootstrapping. Results: : Exhaustion has a statistically significant positive correlation with job stress (r=.40, p ＜.001) and a statistically significant negative correlation with emotional intelligence (r=-.26, p =.004). A partial mediating effect of emotional intelligence is found between job stress and exhaustion, however, there is no moderating effect. Conclusion : It is expected that to reduce the exhaustion of nurses in comprehensive nursing service units, it is necessary to assess job stress and emotional intelligence, and strengthen emotional intelligence along with job stress intervention.

STATEMENT OF PROBLEM: When veneering composite resin-metal restoration is prepared, the fact that bond strength between Ti and composite resin is relatively weak should be considered. PURPOSE: The purpose of this study is to evaluate the shear bond strength between the veneering composite resin and commercial pure (CP) Ti / Ti-6Al-4V alloy according to the method of surface treatment. MATERIAL AND METHODS: The disks were cast by two types of metal. Their surfaces were treated by sandblasting, metal conditioner, TiN coating and silicoating respectively. After surface treatment, the disks were veneered by composite resin (Tescera(TM), Bisco, USA) which is 5 mm in diameter and 3 mm in thickness. The specimens were stored in water at 25degrees C for 24 hours, and then evaluated for their shear bond strength by universal testing machine (STM-5(R), United Calibration, USA). These values were statistically analyzed. RESULTS: 1. All methods of surface treatment were used in this study satisfied the requirements of ISO 10477 which is the standard of polymer-based crown and bridge materials. 2. The metal conditioner treated group showed the highest value in shear bond strength of CP Ti, silicoated group, TiN coated group, sandblasted group, in following order. 3. The silicoated group showed the highest value in shear bond strength of Ti-6Al-4V alloy, metal conditioner treated group, sandblasted group, TiN coated group, in following order. CONCLUSION: Within the limitations of this study, all methods of surface treatment used in this study are clinically available.

Congenital duodenal obstruction is a one of the emergent surgical conditions in neonates. Almost of them were diagnosed with double-bubble sign in prenatal ultrasonography. However, partial obstruction caused from duodenal web could be overlooked. We reported a duodenal web in early childhood. A three-year-old girl visited at our pediatric clinic for constipation. She had been showed non-bilious vomiting after weaning meal since 6 months old of her age, but her weight was relevant for 50-75 percentile of growth curve. Barium enema was initially checked, but any abnormal finding was not found. We noticed the severely distended stomach and 1st portion of duodenum. Upper gastrointestinal series revealed partial obstruction in 2nd portion of duodenum. After laparotomy, we found the transitional zone of duodenum and identified a duodenal web via duodenotomy. We performed duodeno-duodenostomy without any injury of ampulla of Vater. She was recovered uneventfully. During 6 months after operation, she does well without any gastrointestinal symptoms or signs, such as vomiting or constipation.

Palpable inguinal mass in children should be differentiated from inguinal hernia, hydrocele, lymph node, and tumor. Though using ultrasonography, fatty tumor would be misdiagnosed as incarcerated inguinal hernia containing fatty component. We experienced the huge inguinal lipoblastoma in 5-year-old girl mimicking recurrent incarcerated hernia. Laparoscopic exploration revealed it was not incarcerated hernia but well demarcated bulging mass from abdominal wall. Mass was about 10x4x3 cm and extended from internal inguinal ring to saphenous opening. It was near total excised because of right external iliac vein injury. Pathologically, it was proven as lipoblastoma containing mature adipocyte with lipoblast and fibrous septa. Postoperatively, we noticed a segmental thrombotic occlusion of external iliac vein. After 1 year, she has no symptom related to occluded vessel. The remained lipoblastoma showed no interval change. Even lipoblastoma has a good prognosis with low recurrence rate, we need careful follow-up.

BACKGROUND: Quality-adjusted life expectancy (QALE) means life expectancy (LE) reflecting health-related quality of life and is one of the indicators of healthy LE. We determined the trends in QALE in Korea by age, gender, educational level, and subregion from 2005 to 2013. METHODS: We applied the Sullivan method to estimate QALE. We calculated QALE from 2005 to 2013 by gender and QALE for 2005 and 2010 by educational level at the national level. Furthermore, we estimated QALE for 2005, 2008, and 2011 by subregion according to metropolitan and provincial levels. RESULTS: Population health in Korea measured by LE and QALE at age 0 increased steadily from 2005 to 2013. Annual percent changes of LE and QALE in men were 0.52 and 0.73, respectively (P value < 0.05), and those in women were 0.47 and 0.71, respectively (P value < 0.05). Koreans with a higher educational level had longer LE and QALE than those with a lower educational level, but the differences in LE and QALE according to educational level narrowed from 2005 to 2010. The LE and QALE at age 0 for each of the 16 subnational regions in 2011 increased compared to 2005, but there was still a difference of up to 4.57 years in QALE between subnational regions. CONCLUSION We showed that QALE could be easily calculated and be an appropriate measure for tracking the overall population's health level. The results from this study are expected to aid the Ministry of Health of Republic of Korea in setting up a goal for the National Health Plan.

Antral web is a rare cause of gastric outlet obstruction in neonate. It is a 2-4 mm thin mucous membrane that can be found anywhere from 1 to 7 cm proximal to the pylorus. The baby was born at gestational age of 32(+1) weeks with 1,880 g as 2nd baby of dizygotic twin. After birth, the baby had constant non-bilious vomiting without feeding while he didn't show abdominal distension or discoloration. The infantogram showed distended stomach with distal small bowel gas. Upper gastrointestinal series revealed that the antrum was abruptly narrowed at 1 cm proximal to pylorus. We performed laparotomy at the 10th day after birth and excised the 2 mm-thick web circumferentially. He began milk feeding after 6 days and discharged uneventfully at postoperative 35 days with corrected age of 38(+4) weeks with body weight 2,420 g. The antral web should be considered in the case of non-bilious vomiting in neonate.

PURPOSE: This study investigated the risks of development and surgical complications of meconium obstruction (MO) in very low birth weight (VLBW) infants. METHODS: We performed a retrospective medical record review of VLBW infants admitted to the neonatal intensive care unit of Haeundae Paik hospital and diagnosed with MO of prematurity (MOP) between March 2010 and August 2013. RESULTS: Of 267 VLBW infants admitted to the neonatal intensive care unit, 28 were diagnosed with MOP. Perinatal factors including maternal pregnancy-induced hypertension and small for gestational age were associated with MOP development (P<0.05). Over two-thirds of VLBW infants with MOP were successfully treated with a gastrografin enema. The remaining eight VLBW infants required surgery. Although small for gestational age was more frequent in the medical treatment group, specific risk factors associated with MOP development did not affect the need for surgical intervention. CONCLUSION: MOP is common in VLBW infants, as most VLBW infants have risk factors for MOP. Identifying risk factors permits early diagnosis and initiation of appropriate medical treatment, reducing the necessity for surgery. However, the presence of specific risk factors does not increase risk of surgical complications.
