PURPOSE: We carried out this study to determine if there is any difference in the occurrence rate of the epileptiform discharge between awake EEG and sleep EEG and if there are any factors influencing on the occurrence rate of EEG. METHODS: This study included 178 epileptic children who had visited neurology clinic of the department of pediatrics, Pusan National University Hospital from July 2005 to July 2006. The medical and EEG records of these children who had had both awake EEG and sleep EEG were reviewed. We analysed the occurrence rate of the epileptiform discharge between awake EEG and sleep EEG. We investigated the related clinical factors which included sex, seizure types, underlying causes, age at first seizure, antiepileptic drug (AED) medication, age at recording, and background activity. RESULTS: Among 178 epileptic children, 91 patients (51.1%) showed epileptiform discharge in awake or sleep states, 10 patients (11.0%) abnormal only in awake, 40 patients (44.0%) abnormal only in sleep, 41 patients (45.0%) abnormal in both awake EEG and sleep EEG. The occurrence rate of sleep EEG was 81 of 178 patients (45.5%) which was more than that of the awake EEG (28.7%) (P<0.001). The occurrence rate of sleep EEG is more than that of the awake EEG regardless of sex and underlying causes. But there is no significant difference from awake EEG and sleep EEG in finding the epileptiform discharge in the patient with generalized seizure, younger than 5 years old at first seizure, younger than 10 years old at recording, no antiepileptic medication, and abnormal background activity. CONCLUSION: The sleep EEG is thought to be more helpful in the diagnosis of childhood epilepsy.

PURPOSE: This study was to explore subjectivity on childbearing in high school students. METHODS: A Q-methodology which provides a method of analyzing the subjectivity of each type was used. Forty-three high school students classified 40 selected Q-statements into 9 points standard. The obtained data were analyzed by using the pc-QUANL program. RESULTS: High school students' subjectivity on childbearing were analyzed into two types: Type 1 turned out to be 'FOLS (family oriented life style)' and Type 2 'CINK (couple important no kid)'. CONCLUSION: In order to resolve such problems as low birth rate and the advanced age of the population, effective youth and adult programs, policy and institution are required. The current demographic, economic and other factors such as personal values and policies may lower birth rate. In particular, youths' need for children and birth rate tend to be lower. There are positive and negative patterns in high school students' subjectivity on childbearing. Thus, national and social efforts are needed to change negative factors into positive ones. In order to maintain positive subjectivity on childbearing in high school students, it is necessary to apply family-centered educational programs and to implement birth-friendly and realistic programs for promoting child birth.

PURPOSE: Respiratory viral infection is one of the most common diseases in febrile infants. This study evaluates the clinical characteristics of febrile infants who were hospitalized for respiratory symptoms, with or without respiratory viral detection. METHODS: Seventy-six hospitalized infants aged 28-90 days with fever and respiratory symptoms from January 2011 to December 2012 were enrolled in this study. We performed reverse transcriptase polymerase chain reaction to identify 7 respiratory viruses from nasopharyngeal swabs. Also, we retrospectively reviewed the medical records to analyze the clinical features. RESULTS: Respiratory viruses were detected in 45 patients (RVP group). Respiratory syncytial virus (n=16) was most frequently detected, followed by human rhinovirus (n=10). Age, sex, past illness, and sibling's respiratory symptoms showed no differences between the 2 groups. Infants in the RVP group had a significantly higher incidence of tachypnea (22.2%) and abnormal breathing sounds (wheezing and rales, 57.8%) than those in the negative group (P=0.021, P=0.002 each). There were no significant differences in laboratory findings between the 2 groups. CONCLUSION: In our study, RSV was the most common virus in febrile infants aged 28-90 days with respiratory symptoms. Tachypnea and abnormal breathing sounds were more reliable clinical features to guess the detection of respiratory viruses. Further studies are required to confirm the values of these clinical features in febrile infants who have lower respiratory tract infections.

Body surface potential map, an electric potential distribution on the body torso surface, enables us to infer the electrical activities of the heart. Therefore, observing electric potential projected to the torso surface can be highly useful for diagnosing heart diseases such as coronary occlusion. The BSPM for the heart of a patient show a higher level of sensitivity than 12-lead ECG. Relevant research has been mostly based on clinical statistics obtained from patients, and, therefore, a simulation for a variety of pathological phenomena of the heart is required. In this study, by using computer simulation, a body surface potential map was implemented according to various occlusion locations (distal, mid, proximal occlusion) in the left anterior descending coronary artery. Electrophysiological characteristics of the body surface during the ST segment period were observed and analyzed based on an ST isointegral map. We developed an integrated system that takes into account the cellular to organ levels, and performed simulation regarding the electrophysiological phenomena of the heart that occur during the first 5 minutes (stage 1) and 10 minutes (stage 2) after commencement of coronary occlusion. Subsequently, we calculated the bipolar angle and amplitude of the ST isointegral map, and observed the correlation between the relevant characteristics and the location of coronary occlusion. In the result, in the ventricle model during the stage 1, a wider area of ischemia led to counterclockwise rotation of the bipolar angle; and, during the stage 2, the amplitude increased when the ischemia area exceeded a certain size.

Primary aldosteronism is in most cases due either to a unilateral adrenal adenama or to a bilateral hyperplasia of the adrenal cortex. But, a few of bilateral adrena1 tumors in primary aldosteronism also have been reported. In these cases, it is important to differentiate the bilateral aldosterone producing adenomas from the unilateral aldosteronoma in the presence of a contralateral nonhmctioning adenoma for marking a treatment plan. We report a case of primary aldosteronism due to a unilateral aldosteronoma in the presence of a contralateral nonfunctioning adenoma. Abdominal CT sean revealed bilateral adrenal tumors, of which the functioning one was successfully localized using adrenal scintigraphy and selective adrenal venous sampling.

BACKGROUND AND OBJECTIVES: Methicillin-resistant Staphylococcus aureus (MRSA) is one of major pathogens in patients with chronic suppurative otitis media (CSOM). In addition to intrinsic MRSA infection of the mastoid air cell system, nasal colonization of MRSA, a known predictor of postoperative surgical site infection, may pose increased risk of postoperative complications. The purpose of this study is to describe microbiology of preoperative nasal swab screening and localized middle ear specimens in patients undergoing otologic surgeries. SUBJECTS AND METHODS: Forty-nine consecutive patients with CSOM who underwent middle ear surgery were included. Preoperative nasal swabs for MRSA, and preoperative and intraoperative middle ear swabs were collected and compared for pathogens. RESULTS: Preoperative nasal swab screening confirmed MRSA colonization in 3/49 patients (6.1%) and methicillin-resistant coagulase-negative Staphylococcus (MRCNS) in 9/49 patients (18.4%). Correlation with preoperative culture results and nasal swab screening results were compatible in 2/4 patients with positive nasal swab for MRSA and 1/9 patients with positive nasal swab for MRCNS. Postoperative conversion to MRSA was observed in 3 patients. CONCLUSIONS: The rate of nasal MRSA colonization among patients with CSOM was higher than among the general community. Preoperative MRSA colonization was associated with MRSA from middle ear specimens. Further studies are warranted to investigate the possible benefit of preoperative treatment of MRSA colonized patients undergoing middle ear surgeries.

Purpose: A “Smart Cancer Care” platform that integrates patient-reported outcomes (PROs) with management has been established in Korea. This study focused on improving health behaviors and connecting patients to welfare services by introducing and assessing the feasibility of “Smart Cancer Care 2.0,” an enhanced version designed for monitoring complications post-cancer treatment. Materials and Methods: Smart Cancer Care 2.0 was developed by conducting a literature review and consulting with expert panels to identify symptoms or variables requiring monitoring and management guidelines based on the treatment type. Qualitative and quantitative surveys were conducted to assess the feasibility of the app and web system based on the experiences of patients with cancer and healthcare workers. Results: A total of 81 symptoms or variables (chemotherapy-, surgery-, radiotherapy-, rehabilitation-, and health management-related) were selected for management in Smart Cancer Care 2.0. PROs for these symptoms were basically categorized into three severity grades: preventive management, self-treatment, and consultation with a healthcare worker or visit to a healthcare institution. The overall mean scores in the feasibility evaluation by patients and healthcare workers were 3.83 and 3.90 points, respectively, indicating high usefulness. Conclusion Smart Cancer Care 2.0 leverages the existing information and communication technologies–based platform, Smart Cancer Care, and further includes health behaviors and welfare services. Smart Cancer Care 2.0 may play a crucial role in establishing a comprehensive post-discharge management system for patients with cancer as it provides suitable interventions based on patients’ responses and allows the regularly collected PROs to be easily viewed for streamlined care.
