Nasal chondromesenchymal hamartoma is a distinctive mixed mesenchymal lesion of sinonasal region with a complex histologic appearance and benign clinical course and clinicopathologically similar to those of the mesenchymal hamartoma of the chest wall of infancy. We report a case of nasal chondromesenchymal hamartoma occurred in the right nasal cavity in a 3-month-old female. She was admitted with a history of profuse nasal bleeding and obstruction. CT revealed complex solid and cystic mass, measuring 3.5x2.5x2.5 cm in dimensions which filled the right nasal cavity and extended into ethmoid sinus and cribriform plate. The received piecemeal fragments of tissue were brown tan-colored firm semitranslucent tissue with a cartilaginous appearance. Microscopically, the basic morphologic elements were irregular islands of hyaline cartilage and myxoid to spindle cell stroma with various cellularity.

PURPOSE: The purpose of this study was to identify the relationship between self-esteem and sexual attitude in healthcare college students, and also to provide a basis for sexual health education programs to help establish healthy sexual attitudes. METHODS: A survey was conducted with 218 unmarried students attending the healthcare colleges in B and U cities. Data were collected from October 15 to November 10, 2015 and analyzed using Stepwise multiple regression with SPSS PASW 18.0. RESULTS: Mean score for self-esteem was 3.23±0.46 out of 5 and sexual attitude 2.64±0.54 out of 5. Self-esteem and sexual attitude had a negative correlation (r=-.169, p=.012). Among sub-variables of sexual attitude, negative correlations were found between self-esteem and premarital chastity (r=-.207, p=.002), and between self-esteem and homosexual attitudes (r=-.167, p=.013). There were statistically significant differences in sexual attitude according to perceived intimacy with mother (β=-.228, p<.001), year in college (β=.135, p=.047), major (β=.148, p=.023), religion (β=-2.429, p=.016), and homosexual tendencies (β=.139, p=.037). These factors explained 14.6% of the variance in sexual attitude. CONCLUSION: Findings demonstrate the importance of self-esteem for sexual attitudes. This finding should be used in the development of healthcare college students, promotion programs to enhance healthy sexual attitudes.

PURPOSE: This study was to examine the relationships between knowledge with same sub-areas of education needs and adherence to self-management guidelines, and to investigate the factors that influence adherence. METHOD: One hundred eleven patients with terminal stage of kidney failure were conveniently selected from a university hospital in Incheon. RESULTS: The level of knowledge was high, with a mean score of 15.25. The level of adherence to self-management guidelines was low, with a mean score of 64.53. The patients' education needs were high. The significant influencing factors on adherence were gender, educational level, and two sub-areas of knowledge, 'exercise and daily life' and 'follow-up care and treatment'. CONCLUSION: Relationships between knowledge, education needs, and adherence should be further examined before developing and implementing intervention programs for adherence to treatment guideline in hemodialysis patients.

PURPOSE: There has been little research regarding the effectiveness of oseltamivir for influenza B infections. We sought to identify the different clinical manifestations between patients treated with and without oseltamivir. METHODS: We retrospectively studied the medical records of 72 inpatients or outpatients from two medical centers diagnosed with influenza B infections by either a rapid antigen test or multiplex reverse transcriptase PCR between January 2012 and July 2012. We compared gender, age, past medical history, admission period, total fever duration, fever duration after hospitalization, post-oseltamivir medication peak temperature, laboratory test, chest X-ray, antibiotic medication, and the presence of concomitant viral or bacterial infections. RESULTS: The number of subjects in our study was 72 who were diagnosed with influenza B pneumonia, acute bronchitis, acute bronchiolitis, croup, and mean age was 3.6+/-2.8 year old. The demographic characteristics and clinical manifestations of oseltamivir and the non-oseltamivir groups, including hospitalization period (4.18+/-2.10 vs 4.79+/-1.49 days, P=.17) and total fever duration (5.32+/-2.07 vs 6.41+/-3.25 days, P=.09), demonstrated no significant differences. Notably, the oseltamivir group did have significantly reduced usage of antibiotic treatment than the non-oseltamivir group (P=.04). When we limited our patient group to patients under the age of three, similar results were seen. The group prescribed oseltamivir within 48 hours of fever onset had less antibiotic usage, in addition to a shorter fever duration. CONCLUSION: Oseltamivir appeared to have no benefit in improving the clinical course. However, if it is prescribed within the first 48 hours of symptoms, it may be more effective.

Trichuris trichiura (whipworm) is a ubiquitous parasite that resides in the human intestinal tract, and it is known as whipworm because of its whip-like appearance. Trichuriasis is rare in developed countries, but it is more prevalent in tropical countries and areas with suboptimal sanitation. In most patient, whipworm infection is asymtomatic but patient with heavy infection present with anemia, diarrhea, trichuris dysentery syndrome, abdominal pain, weight loss, appendicitis and rectal prolapse. It is characterized by the invasion of the colonic mucosa by the adult Trichuris and produces minor inflammatory changes at the sites of localization. Its diagnosis is usually made by identification of football-shaped eggs in the stool or by confirming adult whipworm during colonoscopy. We report four cases of whipworm infection that were incidentally diagnosed on colonoscopy.

PURPOSE: To determine the characteristics of benign breast calcifications on mammogram. MATERIALS AND METHODS: Benign breast calcifications on mammograms of 25 patients, which were confirmed by needle localization and excisional biopsy(15 cases), cytology(1 case), or follow-up study(9 cases), were retrospectively analysed according to size, shape, number, distribution, and density. RESULTS: The size of benign breast calcifications was uniform in 4 cases (16%), and variable in 21 cases (84%). The shape of calcifications was round or oval in 18 cases(72%), linear or branching pattern in 6 cases (24%), and irregular in 1 case(4%). The number of calcifications was 2-5 in 7 cases(28%), and over 6 in 12 cases(48%). The distribution of calcifications was focal in 13 cases(52%) and diffuse in 12 cases(48%). The density of calcification was homogenous in all 25 cases(100%). CONCLUSION: Analysis of number, shape, size, and distribution is helpful for the diagnosis of benign breast calcifications. However the homogenous density of the calcification is suggested to be the most helpful criterion for the diagnosis of benign breast calcifications.

The purpose of the study was to investigate the influence of an endodontic infection on presence of furcation involvement in periodontally-involved mandibular molars. All first and second mandibualr molars in 45 patients were selected if at least one was root-filled or had a possible periapical radiolucency. The sample consisted of patients from a referral population at a periodotnal clinic which represented an adult population with a mean age of 47.5 years (range 31 to 63) For mandibular molars with periapical destruction at both roots, frequency of horizontal furcation depth > or = 3 mm was significantly more compared to teeth without periapical destruction. Mean periodontal probing depth was significantly greater at mandibular molars with periapical destruction. It is suggested that a root canal infection in periodontitis-involved molars may potentiate periodontitis progression by spreading of endodontic pathgens through patent accessory canals and dentinal tubules. In conclusion, an endodontic infection in mandibular molars was found to be associated with additional attachment loss in the furcation area, and may thus be considered to be one of several risk factors influencing the prognosis of molars in periodontitis-prone patients.

PURPOSE: Recently, early surfactant replacement and tidal volume based gentle ventilation has been a fundamental treatment of respiratory distress syndrome (RDS). The aims of this study were to survey the changes in ventilator care duration and rate of complication in RDS groups. METHODS: We performed a retrospective study of 255 newborn infants less than 1, 500 g admitted to the neonatal intensive care unit (NICU) and discharged from January 1999 to December 2003. 141 of 255 newborn infants were RDS groups that required invasive management, such as endotracheal intubation, surfactant replacement and assisted ventilation. We analyzed epidemiologic data to study the changes in ventilator care duration and outcome of RDS groups. RESULTS: Of 141 RDS groups, 135 were mild to moderate RDS groups and only 6 were severe RDS groups. 24 (17.8%) of 135 mild to moderate RDS groups and 3 (50%) of 6 severe RDS groups were antenatal no use of maternal dexamethasone. 127 (90.1%) of 141 RDS groups underwent replacement of surfactant during 3 hours after birth. 121 (85.9%) weaned within 48 hours. CONCLUSION: Our study shows a decreased frequency of severe RDS by a antenatal use of maternal dexamethasone and decreased duration of ventilator care by early surfactant replacement and gentle ventilation.

OBJECTIVES: Seoul-Activities of Daily Living(S-ADL) was developed to assess elderly person's basic activities of daily living. This study aims to develop standardized ADL assessment scale and confirm the reliability and validity of the S-ADL. METHODS: It was participated in 336 controls and 145 patients diagnosed Alzheimer's disease. RESULTS: In controls, it was statistically significant to age, but not sex, education, region and presence of spouse. Also, reliability and validity were statistically significant. Principal axis factoring analysis revealed three factors that accounted for 66.67% of the total variance(1.self-care/hygiene, 2.ambulation, 3.toileting). According to each CDR stage, there were significant difference, except for CDR 0.5 and CDR 1 suggesting early dementia. Particularly, it was remarkable for functional impairment in CDR 2 and CDR 3 suggesting moderate to severe dementia. The order of the loss of function was (1) self-care/hygiene, (2) toileting, and (3) ambulation. CONCLUSIONS: Our study showed that the S-ADL could be a very reliable and valid tool for the assessment of functional disabilities of Korean dementia patients. Particularly, S-ADL would be useful in assessing daily function of moderate to severe AD.

Purpose: The purpose of this study was to examine the correlations among emotional perception clarity, emotion regulation, family relationship, non-suicidal self-injury, and depression, and to determine associated factors of non-suicidal self-injury and depression for senior elementary school students. Methods: Data were collected from 150 early adolescences in K region, Korea. A self-report questionnaire consisted of Trait Meta-Mood Scale, Cognitive Emotion Regulation Questionnaire, Family Relationship Assessment Scale, Functional Assessment of Self-Mutilation, and Children's Depression Inventory. The data were analyzed using t-test, Pearson’s correlation coefficient, logistic regression, and multiple regression analysis. Results: Non-suicidal self-injury and depression were positively associated with maladaptive emotion regulation strategy and family conflict, but negatively related to emotional perception clarity and family support. Adaptive emotion regulation strategy and family togetherness were only significantly correlated with depression. In logistic regression analysis, significant predictors of non-suicidal self-injury were emotional perception clarity, maladaptive emotion regulation strategy, and family support. Multiple regression analysis found that significant factors of depression were adaptive and maladaptive emotion regulation strategies, which explained 38.0% of the variance. Conclusion Our study findings suggest that targeted intervention to reinforce the adaptive emotion regulation strategy and family relationship may prevent non-suicidal self-injury, and depression for senior elementary school students.
