BACKGROUND: Nutrition label reading is helpful in attaining a healthy diet. Nutrition label use and its related factors have been studied in many Korean articles, but their research samples were the general population and not chronic disease patients. This study aimed to explore the use of nutrition labels and its relation to dietary intake among chronic disease patients in Korea. METHODS: A total of 3160 respondents aged> or =20 years from the 2008-2009 Fourth Korean National Health and Nutrition Examination Survey (KNHANES-IV) participated in the study. Their chronic medical conditions included hypertension, hyperlipidemia, coronary artery disease, diabetes and/or stroke and they were interviewed regarding their use of nutrition labels. Nutrition intake was also estimated by 24-hour dietary recalls. RESULTS: Overall, 10.4% of the chronic disease patients reported to using nutrition labels. The nutrients they looked at first were total calories, fat and cholesterol. Factors related to reading nutrition labels were relatively higher education, high body mass index and lower frequency of alcohol intake in males and relatively younger age and higher education in females. Nutrition label users consumed lower total calories, protein and fat in the male CAD group, lower total calories and carbohydrate in both diabetes and total groups and lower total calories and fiber in the female stroke group. CONCLUSIONS: Our study found that, in Korea, a significantly lower rate of patients with chronic disease read nutrition labels. Strategies need to be developed to improve clinical application of nutrition labels in this population.

PURPOSE: Accurate evaluation of side branch (SB) ostium could be critical to the treatment of bifurcation lesions. We compared measured and calculated values of side branch ostial length (SBOL) in coronary bifurcation lesions with intravascular ultrasound (IVUS). MATERIALS AND METHODS: Pre-intervention and post-intervention IVUS was performed in 113 patients who underwent stent implantation of bifurcation lesions. For the IVUS longitudinal reconstruction of the bifurcation lesions, SBOL, SB diameter, and the angle between the distal portion of the main vessel (MV) and SB were directly measured. In addition, SBOL was calculated as: SB diameter/sin (angle between distal MV and SB). The relationship between measured and calculated SBOL was then evaluated. RESULTS: The angled between the distal MV and SB were 57.3+/-12.4degrees at pre-intervention and 59.4+/-12.6degrees at post-intervention. The mean measured and calculated SBOL values were 2.91+/-0.86 mm and 3.06+/-0.77 mm at pre-intervention and 2.79+/-0.82 mm and 2.92+/-0.69 mm at post-intervention, respectively. Differences between measured and calculated SBOL were 0.15+/-0.44 mm at pre-intervention and 0.13+/-0.41 mm at post-intervention. We found that calculated SBOL was correlated with measured SBOL (pre-intervention r=0.863, p<0.001; post-intervention r=0.868, p<0.001). CONCLUSION: There was a good correlation between measured and calculated SBOLs of the bifurcation lesions in IVUS longitudinal reconstruction. SBOL in the bifurcation lesions can therefore be estimated using the SB diameter and the angle between distal MV and SB.

BACKGROUND AND OBJECTIVES: With recent advances in equipment and techniques, infrapopliteal angioplasty has shown results that are comparable to those of surgical bypass in patients with critical limb ischemia (CLI). In this study, we evaluated the efficacy and the feasibility of infrapopliteal angioplasty in patients with CLI. SUBJECTS AND METHODS: Between March 2002 and May 2008, infrapopliteal angioplasty was performed on 118 limbs of 101 patients (79 males; mean age 66 years) with CLI (Rutherford category 4, 5 or 6). Freedom from reintervention, limb salvage, and overall survival were analyzed. RESULTS: The median follow-up duration was 30 months. Initial technical and clinical success rates were 69.5% and 83.1%, respectively. No major complication requiring surgical intervention developed after angioplasty. Among 82 limbs with initial technical success, the rate of freedom from any reintervention at 2 years was 70.7% and that from limb salvage was 97.6%. Young age and Rutherford category 6 at initial presentation were independent predictors associated with poor 2 year primary patency in these patients with CLI. Overall survival at 1 year was 86.4% and that at 2 years 76.3%. A history of cerebrovascular accident was an independent predictor associated with poor 2 year survival in these patients. CONCLUSION: Infrapopliteal angioplasty as a primary choice of treatment in CLI patients showed favorable clinical outcomes and feasibility.

PURPOSE: To analyze difference in bone mineral density (BMD) between intertrochanteric fracture and control group and to explore the predictive value of BMD for intertrochanteric fracture. MATERIALS AND METHODS: 57 patients who were over 60-year-old with intertrochanteric fracture were examined. For control group, 110 patients who did not have any fracture were selected. Dual energy X-ray absorptiometry was studied at 1, 2, 3, 4 lumbar vertebrae, femoral neck, trochanter and Ward's triangle. BMD was compared at each site between two groups statistically. RESULTS: Fracture group consisted of 16 male, 41 female and was average 70.8 year old. Control group consisted of 21 male, 89 female and was average 68.1 year old. There was no differences in sex and age between two groups (p>0.05). BMD of L1, L2 and mean lumbar area were significantly less in fracture group than control group (p<0.05). There was no difference between two groups in BMD of another sites (p>0.05). CONCLUSION: BMD of L1, L2 and mean lumbar area in fracture group had lower value significantly, but had no differences between two groups at another sites. BMD of L1, L2 and mean lumbar area might be used as the most sensitive predictive indicator for risk of osteoporotic fractures including intertrochanteric fracture in elderly patient.

BACKGROUND AND OBJECTIVES: Eosinophils play a major role in the pathophysiology of chronic rhinosinusitis with nasal polyposis (CRS/NP). The secreted form of eosinophil cationic protein (ECP) is considered to be the marker of eosinophil activity. The aim of this study is to investigate the relationship between serum ECP and CRS/NP. SUBJECTS AND METHOD: A retrospective review of medical records was carried out on 198 patients who had undergone endoscopic sinus surgery from March, 2001 through July, 2006 at our institution. We reviewed blood eosinophil counts, tissue eosinophil, serum ECP, symptom scores, CT scan scores according to the Lund-Mackay system, recurrence of polyp and revision surgery during follow-up. RESULTS: The serum ECP concentration was significantly higher in the CRS/NP patients than in the normal control subjects. The serum ECP concentration was significantly correlated with the blood eosinophil count, CT score and tissue eosinophil count. The serum ECP concentration was significantly higher in patients with recurrence or revision surgery than in patients without recurrence or revision surgery. CONCLUSION: The results suggest that the level of serum ECP is correlated with the disease severity, and is one of prognostic factors after endoscopic sinus surgery.

PURPOSE: We investigated whether the Valsalva leak point pressure (VLPP) is valuable for predicting postoperative outcome measurement after transobturator suburethral tape (TVT-O) implantation for treating stress urinary incontinence (SUI) in women. MATERIALS AND METHODS: A total of 204 female patients who underwent TVT-O placement for treatment of SUI from March 2008 to February 2012 were enrolled in this retrospective study. All patients completed the incontinence quality of Life questionnaire (I-QoL), a self-reported quality of life measure specific to urinary incontinence, and the cure rate of incontinence was measured before and 6 months after surgery. Cure was defined as no leakage of urine postoperatively both subjectively and objectively. We compared pre- and postoperative I-QoL scores according to preoperative VLPP and Stamey grade. RESULTS: The numbers of patients with Stamey grades I, II, and III were 99 (48.5%), 84 (41.2%), and 21 (10.3%), respectively. A total of 30 (14.7%), 87 (42.6%), and 87 patients (42.6%) showed VLPP< or =60, 6090 cm H2O, respectively. Preoperative VLPP was not significantly different according to preoperative I-QoL or change in I-QoL after surgery. However, I-QoL after surgery improved in patients with a high preoperative Stamey grade (p=0.001). CONCLUSIONS: VLPP was not a factor related to surgical outcome from the midurethral sling procedure. Stamey grade rather than VLPP was important for predicting subjective quality of life and improved incontinence-related quality of life after surgery.

BACKGROUND AND OBJECTIVES: Allergic rhinitis is closely related to asthma. The skin prick test is an essential diagnostic tool for allergic disease. We evaluated differences in skin sensitization patterns between groups of patients with allergic rhinitis or asthma, or allergic rhinitis with asthma, in Korea. MATERIALS AND METHODS: From 2000 to 2009, patients with positive results from skin prick testing were divided into three groups: allergic rhinitis (AR), allergic asthma (AS), and allergic rhinitis with allergic asthma (AR+AS). We analyzed demographic data, rhinitis and asthma symptoms, and sensitization patterns. RESULTS: The most common aeroallergen was the house dust mite. The age distributions of the three disease groups differed significantly. Sensitization number, sensitization index, and atopy index were all significantly higher among the AR+AS group than among the AR or AS groups. CONCLUSION: Patients with allergic rhinitis with high numbers of skin sensitizations or intensive positivities should be considered to have concomitant asthma or to be at high risk for asthma development.

BACKGROUND AND OBJECTIVES: Several studies have reported the benefits of olfactory training (OT) for patients with olfactory dysfunction. However, training odorants should be customized according to the characteristics of individual patients. The aim of this study was to evaluate the effects of OT using odorants familiar to Korean patients with post-upper respiratory infection (URI) olfactory dysfunction. SUBJECTS AND METHOD: We prospectively evaluated patients with post-URI olfactory loss. We carried out OT over a period of 6 months using four odorants: pine, cinnamon, lemon, and peppermint. Olfaction was tested before and at 1, 3, and 6 months after training initiation using the following olfactory tests; Butanol threshold test (BTT), Cross-Cultural Smell Identification Test (CCSIT) and Visual Analog Scale (VAS), Nasal Obstruction Symptom Evaluation (NOSE) scale, Sino-Nasal Outcome Test (SNOT-20), and Beck Depression Inventory (BDI). RESULTS: Of the 88 patients who initially enrolled, 82 completed the BTT, CCSIT, VAS, NOSE, SNOT-20, and BDI. In total, 10 Korean patients were included in our analysis, nine of whom showed an improvement in olfaction after OT. All patients reported changes in olfaction and the perception of smells over the duration of OT. Some patients reported an increased sense of smell after OT, although he could not distinguish different smells. CONCLUSION: OT using odorants specifically selected for Korean patients resulted in improved olfactory function, as indicated by the BTT and CCSIT scores. The findings of the present study suggest that customization of odorants to fit the characteristics of patients, including ethnicity, environment, and race, among others, increases the effectiveness of OT.
