BACKGROUND: Bacteriokiller system(BKS) produces disinfectant which is generated by the mixture of active oxygen and hypochlorous acid with tap water. Previous studies showed that BKS disinfectant is highly bacteridal against clinical isolates in in vitro testings and more effective than general soap and water for the disinfecttion of contaminated handa. This study was performed to evaluate ling-trem effects of BKS as a handwasing agent in clinical settings. METHODS: Five BKS were installed for the 9-month period from June 1995 to February 1996 in 16-bed Neurosurgery Intensive Care Unit. Handwashing was frequency was observed after 1, 6, and 8 month of BKS use. Six-month incidences of nosocomial infecrion before and after BKS installation were compared to evaluate the possible effect of handwashings on nosocomial infection rates. A self-administered questionaire was used to collect data on handwashing frequency and their opinions of the BKS disinfectant at 2 and 8 months after the installation. RESULTS: Handwashing frequency of healthcare workers(HCWs) before and after patient contacts was increased from 34.1%(137/402) to 50.3%(193/384) (p<0.00001). At the same time, the 6-month nosocomial infection rate was down to 10.5%(43/411) from the pre-BKS rate of 13.0%( 51/431) and the patient-day rate was also decreased from 18.3(56/3068) to 15.1(43/2,844). Most (80.5%) of HCWs thought that BKS promote handwashing and "convenience" was the main reason for more frequent handwashing. Ninety three percent of HCWs would recommend the replacement of tne existing sinks and handwashing disinfectants with BKS. NO adverse skin reaction were reported after 8 months. Conclusions: BKS appears to promote handwashing because it is easy to use with no skin irritation and may contribute toward the prevention of nosocomial infections.

OBJECTIVE: We aimed to investigate the relationship between adipokines and antioxidation enzyme and the risk of progression of symptomatic intracranial atherosclerotic stenosis (ICAS). METHODS: Of 409 patients who participated in the TOSS-2 (trial of cilostazol in symptomatic intracranial stenosis-2) study, 52 patients showed progression of symptomatic ICAS on magnetic resonance angiography at seven months after an index stroke. We randomly selected 20 patients with progression and 20 age- and sex-matched control patients. We serially collected blood sample initially, one month, and seven months after an index stroke. Then, multiplex analysis of biomarkers was performed for adiponectin, resistin, leptin, and superoxide dismutase-1, 2, 3. RESULTS: Demographic features and risk factors such as hypertension, diabetes, and smoking history were comparable between the two groups. Control group showed higher adiponectin levels at 7 months than progression group (P=0.05) and a significant in-creasing trend (P for trend=0.01). Resistin, leptin, and superoxide dismutase-1, 2, 3 levels were not different between the progression and control group initially, one month, and seven months after an index stroke. CONCLUSION: Increase of adiponectin level showed protective effect in the progression of ICAS. Resistin, leptin, and superoxide dismutase-1, 2, 3 levels are not different between the groups. Further large numbers of patients with longer follow-up studies are needed.

PURPOSE: This study aims to investigate gender differences in the association between depressive symptoms and weight, weight perception, and body satisfaction among Korean adolescents. METHODS: A secondary data analysis was performed on data from 33,374 adolescents who participated in the 2015 Adolescent Health Behavior Online Survey. They were classified as underweight, normal weight, or overweight/obese; weight perception was classified into perception of being underweight, normal weight, or overweight/obese; and weight satisfaction into desire to gain weight, satisfied, and desire to lose weight. RESULTS: Among boys, perception of being underweight (adjusted odds ratio [AOR]: 1.20, 95% confidence interval [CI]: 1.07~1.35) and desire to gain weight (AOR: 1.45, 95% CI: 1.30~1.62) were associated with depression. Among girls, perception of being overweight or obese (AOR: 1.18, 95% CI: 1.07~1.29) and a desire to lose weight (AOR: 1.30, 95% CI: 1.18~1.42) were associated with depression. CONCLUSION: Gender differences were observed in the association between weight perception and depression in adolescents. The perception of being underweight among boys and the perception of being overweight/overweight among girls were associated with depression. Thus, gender-specific intervention programs to correct weight perception and weight satisfaction are needed in order to relieve depressive symptoms in adolescents.

OBJECTIVE: Acute appendicitis is one of the most urgent surgical problems. Several factors have been considered as predictors of perforation, but this study focused on the change in pain pattern. The degree of pain and progression of appendicitis were analyzed assuming that the pain intensity would increase until the perforation and the degree of pain would decrease immediately after the perforation occurred. METHODS: In this study, 385 out of 467 patients, who were diagnosed with appendicitis in a single institution and aged between 15 and 65 years, were reviewed retrospectively. The patients' pain scores and the diameters of appendices were analyzed along with the accompanying complications. Correlation analysis and a Student's t-test were performed. RESULTS: In patients with complicated appendicitis, the mean numerical rating scale (NRS) was slightly higher than that of simple appendicitis, but there was no significant difference in the absolute value. Only the size of the appendix showed meaningful differences according to the combined computed tomography findings. The NRS distribution or appendiceal size did not correlate with the time duration from symptom onset. CONCLUSION: The appendiceal size tended to increase with progressing appendicitis. No significant correlation was observed between the patient's pain level and complications. The time duration from symptom onset did not show a relationship with the progression of appendicitis.

PURPOSE: To evaluate the incidence of sacral insufficiency fracture in osteoporotic patients with compression fracture of the thoracolumbar (T-L) spine on magnetic resonance image (MRI), and to analyze the correlation of variable clinical factors and the incidence of sacral insufficiency fracture. MATERIALS AND METHODS: We retrospectively reviewed 160 patients (27 men, 133 women; age range of 50 to 89 years) who underwent spinal MRI and had compression fracture of the T-L spine. Compression fractures due to trauma or tumor were excluded. We evaluated the incidence of sacral insufficiency fracture according to the patients' age, sex, number of compression fractures, and the existence of bone marrow edema pattern of compression fracture. During the same period, we evaluated the incidence of spinal compression fracture in the patients of pelvic insufficiency fracture. RESULTS: Out of the 160 patients who had compression fracture in the T-L spine, 17 (10.6%) had insufficiency fracture of the sacrum. Compression fracture occurred almost 5 times more frequently in women (27:133), but the incidence of sacral insufficiency fracture was 2/27 for men (7.4%) and 15/133 for women (11.3%), with no statistically significant difference (p = 0.80). According to age, the ratio of insufficiency fracture to compression fracture was 0% (0/23) in the 50's, 10.6% (7/66) in the 60's, 12.5% (7/56) in the 70's, and 20.0% (3/15) in the 80's. In respect of single and multiple compression fracture, the incidence of sacral insufficiency fracture was 8/65 for men (12.3%) and 9/95 for women (9.5%), showing no significant difference (p=0.37). In the patients with and without compression fracture with bone marrow edema, insufficiency fracture occurred in 5/76 (6.6%) and 12/84 (14.3%), respectively. On the other hand, of the 67 patients who had pelvic insufficiency fracture, 27 (40.3%) also had spinal compression fracture. CONCLUSION: About 10% of the patients with osteoporotic compression fracture in the T/L spine also had pelvic sacral insufficiency fracture, which was not uncommon. These findings suggest the need to consider the possibility of pelvic sacral insufficiency fracture in cases of T/L spinal MRI for patients with osteoporotic compression fracture.

Ovarian tumors of an epithelial origin in pediatric age are uncommon and mucinous cystadenoma, borderline malignancy is extremely rare. We experienced a case of ovarian mucinous cystadenoma, borderline malignancy in a 14-year-old girl. She was admitted due to huge abdominal distension for 2 months. Her past history and family history were normal. The physical examination was normal except tense and distended abdomen. All laboratory findings were normal. On abdominal ultrasonography and CT scan, a huge cystic tumor filled with fluid and inner multiseptation was noted. Unilateral salphingo- oophorectomy was done and pathologic findings were compatible with ovarian borderline malignancy of mucionous cystadenoma. The postoperative course was uneventful.

PURPOSE: The present study assessed the diagnostic significance of digital infrared thermal imaging (DITI) in determining the inflammatory state of patients with nonspecific orbital inflammation. METHODS: The present study included 11 patients diagnosed with nonspecific orbital inflammation between December 2009 and March 2011 and who were followed-up for more than 6 months. All patients were all diagnosed based on computed tomography (CT), magnetic resonance image (MRI) and tissue biopsy. The grade of eyelid swelling was classified as 5 and severe compared with the temperature of location. The temperature of the upper eyelid, caruncle, medial conjunctiva, lateral conjunctiva, lower eyelid, cornea and lateral orbit were measured with DITI. RESULTS: When comparing the normal eye with the diseased eye in patients with nonspecific orbital inflammation, the temperature of the upper eyelid and cornea were statistically significant (p = 0.003, p = 0.038, respectively, Mann-Whitney test). The correlation between the grade of eyelid swelling and the temperature of location was most highly related in the temperature of the upper eyelid (Spearman's correlation coefficient, r = 0.55, p = 0.008) and cornea (Spearman's correlation coefficient, r = 0.45, p = 0.037). CONCLUSIONS: DITI may aid in evaluating the inflammatory state of nonspecific orbital inflammation. In particular, the temperature of the upper eyelid and cornea can be very useful indicator. Future studies, including larger study population are necessary in order to confirm DITI as a diagnostic tool which can assess the results of medical treatment by comparing temperature before and after treatment.

Background: and PurposeThe impact of fluid-attenuated inversion recovery hyperintense vessels (FHVs) on outcomes in patients ineligible for recanalization therapy with large-vessel occlusion (LVO) is unclear. We investigated the impact of FHVs determined using the FHV– Alberta Stroke Program Early CT Score (ASPECTS) on clinical outcomes in patients with LVO stroke of mild-to-moderate severity ineligible for recanalization therapy. Methods: Sixty-eight consecutive patients with M1-middle cerebral artery occlusion who underwent magnetic resonance imaging within 24 hours of symptom onset and were ineligible for recanalization were included. Patients were dichotomized into a severe-FHV group (FHV-ASPECTS ≤4; n=33) and a mild-FHV group (FHV-ASPECTS >4; n=35), and multiple logistic regression analysis was used to examine the relationships of FHV scores with early neurological deterioration (END) and an unfavorable 3-month outcome (modified Rankin Scale score ≥3). Results: Mean age was 66.2±13.5 years (mean±SD), and 30 (44%) were female. The severe-FHV group had a larger infarct volume (median, 5.5 mL vs. 3 mL) and more frequently exhibited the susceptibility vessel sign (30% vs. 3%) than the mild-FHV group. Ipsilateral old nonlacunar infarct was more frequent in the mild-FHV group than in the severe-FHV group (37% vs. 15%). The severe-FHV group had a fivefold higher risk of END (odds ratio [OR] 5.02, 95% confidence interval [CI] 1.36–18.45) and unfavorable outcome (OR 5.97, 95% CI 1.18–33.31, p=0.03) compared with the mild-FHV group. Conclusions Greater FHV extent was associated with higher risk of END and unfavorable outcome in patients with LVO stroke of mild-to-moderate severity.
