This study was intended to investigate the sodium-related perception, dietary behavior, and practicability of methods for reducing sodium intake(RSI) according to the stage of change in consumers. The survey was conducted to 770 housewives, among them 553 subjects who answered the key questions for the stage of change were categorized into ''aintenance (M)' stage (maintaining reduced salt intake for more than 6 months; n = 287, 51.90%), 'Action (A)' stage (maintaining reduced salt intake for less than 6 months; n=139, 25.14%), and 'Pre-Action (P)'stage (not starting reduced salt intake; n = 127, 22.97%). The subjects in M and A were significantly older than those in P (p < 0.01). The scores of desirable dietary habit and dietary balance were the highest in M followed by A and P. When eating out, the subjects in P considered 'price' more and 'healthiness of food' less than those in M and A did. Among the guidelines for RSI, 'Avoid Processed Foods', 'Eat enough vegetables and fruits' and 'Add little amount of dipping sauce for fried food' were selected as the three easiest items to perform. With regard to the sodium-related perception, the subjects in M considered eating-out food to be more salty than homemade dishes, read nutrition labels more, avoided table salt or dipping sauce for fried food more, and had 'own low-sodium recipe' than those in P (p < 0.001). It is suggested that practicability of actions for RSI and the stage of change should be considered to develop effective personalized education program and nutrition guidance.

BACKGROUND: Methicillin-resistant Staphylococcus aureus (MRSA) is one of the major pathogens of nosocomial infections. Especially in intensive care units (ICUs) and nasal carriage of Staphylococcus aureus has been known as a major risk factor of staphylococcal infections. In Korea, MRSA is the most common pathogen of nosocomial infections in ICUs. We performed this study to investigate the effects of conventional control measures and the additional effect of intranasal fusidic acid in prevention of MRSA nasal carriage and infection in ICUs of one educational hospital in Korea. METHOD: All patients admitted to medical ICU and surgical ICU in Samsung medical center from April to September 1999 were studied prospectively. Surveillance culture was done in all patients and health care workers by nasal swab culture. We tried to control MRSA infection by conventional methods in the first period April-June 1999) and by additional intranasal fusidic acid application in the second period (July-September 1999) RESULTS: Comparing the first with second periods, new nasal MRSA colonization rate among patients was significantly decreased from 14.8% to 1.8% in surgical ICU (P=0.016). Although there was no statistical difference between the first and second periods in medical ICU (14.6% vs 5.9%, P=0.192), the new nasal colonization of the first period was significantly decreased than that of the previous study which was performed in 1996 (14.6% vs 36.2%, P=0.015). And new MRSA infection rate was much more decreased than the previous study, but there was no statistical significance (11.7% vs 2.0%, P=0.066). CONCLUSION: Conventional methods for MRSA control decreased new MRSA nasal colonization of patients in ICUs. Application of intranasal fusidic acid was considered as an additional control measure for reducing MRSA nasal colonization. For evaluating effect of intranasal fusidic acid for preventing of MRSA infection in ICUs, further study with larger scale of study population is warranted.

PURPOSE: This study focused on the evaluation of the relation between pollen concentration and the outbreak of allergic disease (symptom index), and this outcome would be necessary to upgrade risk grade for the pollen forecasting system. METHODS: Airborne particles carrying allergens, such as pollen, were collected daily at the Seoul and Guri area by using 7-day Burkard samplers for 6 years. A total of 596 Subjects were recruited from Hanyang University Seoul Hospital (n=144 for spring, n=139 for autumn), and Hanyang University Guri Hospital (n=157 for spring, n=156 for autumn). Symptom index was evaluated and recorded by phone calling to study subjects daily or asking questionnaire when they visit outpatient clinic every week. Statistical analysis of data was performed by using correlation coefficients and regression models with time series graph. RESULTS: Two peak seasons of pollen concentration were May and September in Korea. In skin prick tests, the sensitization rate to ragweed pollen was gradually increased in children. In the same period, sensitization rates to airborne pollen, especially oak, birch for spring, and Japanese hop for autumn were increased annually. There was a significantly relationship between symptom index of allergic patients and allergic pollen concentrations in this study. Especially symptom index was significantly correlated to the concentration of oak pollen of day 1 in spring and to the concentration of Japanese hop pollen of day 0 in autumn. CONCLUSION: Sensitization rates to pollens increased annually. There is a significant relationship between allergy symptom index and pollen concentration. There remains to confirm the Korean own risk grade of pollen allergy.

BACKGROUND: Facial rejuvenation can be achieved using a variety of techniques. Since minimally invasive procedures for face lifting have become popular because of their convenience and short operating time, numerous minimally invasive surgical procedures have been developed. In this study, a nonabsorbable polypropylene mesh is introduced as a new face lifting instrument, with the nasolabial fold as the main target area. In this paper, we report the efficacy and safety of a polypropylene mesh in midface rejuvenation. METHODS: Thirty-three subjects with moderate-to-severe nasolabial folds were enrolled from two medical institutions for a noncomparative single-sample study. A mesh was inserted above the superficial muscular aponeurotic system layer, reaching the nasolabial folds through a temporal scalp incision. After 3 weeks, the temporal end of the mesh was pulled to provide a lifting effect. Then, the mesh was fixed to the deep temporal fascia using nonabsorbable sutures. To evaluate efficacy, we compared the scores on the Wrinkle Severity Rating Scale and a visual analog scale for patient satisfaction between the baseline and 7 weeks postoperatively. In addition, we evaluated safety based on the incidence of adverse events. RESULTS: The treatment was deemed effective at improving wrinkles in 23 of 28 cases, and patient satisfaction improved significantly during the study period. There were seven cases of skin or subcutaneous tissue complications, including edema and erythema, but there were no suspected serious adverse events. CONCLUSIONS: Face lifting using a nonabsorbable mesh can improve nasolabial folds without serious adverse effects. Thus, this technique is safe and effective for midface rejuvenation.

The acute tumor lysis syndrome is an acute illness caused by massive cell lysis after chemotherapies. This syndrome is characterized by hyperuricemia, hyperphosphatemia with hypocalcemia and hyperkalemia. Among these electrolyte abnormalities, the most serious complication is the severe hyperphosphatemia (greater than 14mg/dL) that could result in sudden cardiac arrest or respiratory failure. In order to correct the severe hyperphosphatemia, hemodialysis has been used commonly as the renal replacement therapy . However the hemodialysis can make posthemodialysis serum phosphate rebounded unless the patient take this treatment for more than 6 hours. Therefore it is not sufficient to use hemodialysis treatment alone. To solve this problem, hemodialysis has been used with or replaced by the uninterrupted dialysis technique such as CRRT (continuous renal replacement therapy). We report a 33-year-old man with Burkitt lymphoma who showed severe hyperphosphatemia (peak phosphate value was 18.6mg/dL) during the course of chemotherapy. used with 5 day CAVH (continuous arteriovenous hemofiltration) his phosphate level could be maintained without any rebound. Therefore we concluded that CAVH in conjunction with hemodialysis would be a successful way to control severe hyperphosphatemia associated with tumor lysis syndrome.

PURPOSE: Suicide attempts are known to be influenced by mass media reports. The purpose of this study was to evaluate the effects of mass media reporting celebrity suicides on an increase of intentional carbon monoxide (CO) poisoning and suicide attempts. METHODS: We retrospectively reviewed the medical records of the consecutive patients who presented with suicide attempts to the Emergency Department of Ajou University Hospital during a 24 month period. We obtained the demographic data, any past history of suicide attempt and the methods of suicide attempts from the medical records of the suicide attempters. Time series analysis was conducted for evaluating the influence of mass media reporting of celebrity suicide on the suicide rates. RESULTS: We finally enrolled 770 patients during the study period. The total number of suicide attempts by CO poisoning was 18 and the average number of suicide attempts by CO was 0.33+/-0.73 per week. All of the suicide attempts by CO poisoning occurred after a celebrity committed suicide using CO from burning charcoal. CONCLUSION: This study showed that celebrity suicide by CO poisoning resulted in the Werther effect, which made the rate of intended CO poisoning increase, and the study provided further evidence for the need to actively restrain mass media reporting of suicide to decrease the Werther effect.

PURPOSE: To evaluate the clinical outcome and other relevant factors in cases where local intra-aterial thrombolysis (LIT) is used for the threatment of hyperacute ischemic stroke. MATERIALS AND METHODS: Forty-eight hyperacute ischemic stroke patients were treated by LIT, using urokinase, within six hours of ictus, and for evaluation of their neurological status, the National Institutes of Health Stroke Scale (NIHSS) score was used. Angiographic recanalization was classified according to Mori recanalization grades. Three months after LIT, the outcome was assessed by clinical examination using the modified Rankin scale (good outcome: RS=0-3; poor outcome: RS=4-6). In all patients, the findings of pre- and post- LIT CT, and angiography, as well as neurological status and hemorrhagic complications, were also analysed. RESULTS: Thirty-three patients had occlusions of the middle cerebral artery (MCA), and 15, of the internal carotid artery (ICA). The NIHSS score averaged 16.9 at the onset of therapy and 13.5 at 24 hours later. Successful recanalization (Mori grade 3,4) was achieved in 28 (58.3%) of 48 patients, but in 20 (41.7%) the attempt failed. Twenty-two (45.8%) of the 48 patients had a good outcome, but in (54.2%) the outcome was poor. Thirteen (40.6%) of 32 patients with MCA occlusions and 13 (81.2%) of 16 with ICA occlusions had a poor outcome. Eight patients (16.7%) died. Overall, hemorrhages occured in 20 (41.7%) of 48 patients, with symptomatic hemorrhage in ten. Five (50%) of these ten died. CONCLUSION: LIT using urokinase for hyperacute ischemic stroke is feasible; patients with MCA occlusions had better outcomes than those with ICA occlusions. Hemorrhagic complications of LIT were frequent, and in cases of symptomatic hemorrhage a fatal outcome may be expected.

This study aimed to evaluate the differences in the baseline characteristics and patterns of antibiotic usage among hospitals based on their participation in the Korea National Antimicrobial Use Analysis System (KONAS). We obtained claims data from the National Health Insurance for inpatients admitted to all secondary- and tertiary-care hospitals between January 2020 and December 2021 in Korea. 15.9% (58/395) of hospitals were KONAS participants, among which the proportion of hospitals with > 900 beds (31.0% vs.2.6%, P < 0.001) and tertiary care (50.0% vs. 5.2%, P < 0.001) was higher than that among non-participants. The consumption of antibiotics targeting antimicrobial-resistant gram positive bacteria (33.7 vs. 27.1 days of therapy [DOT]/1,000 patient-days, P = 0.019) and antibiotics predominantly used for resistant gram-negative bacteria (4.8 vs. 3.7 DOT/1,000 patient-days, P = 0.034) was higher in KONAS-participating versus -non-participating hospitals. The current KONAS data do not fully represent all secondary- and tertiary-care hospitals in Korea; thus, the KONAS results should be interpreted with caution.
