Comparison of the portion sizes of Korean adults across eating places:Korea National Health and Nutrition Examination Survey (2012–2016) / 한국영양학회지

Purpose@#The purpose of this study was to investigate the differences in portion size of 11 types of foods that Korean adults frequently consume, based on the parameters of eating place, gender, and age using the Korea National Health and Nutrition Examination Survey (KNHANES) data. @*Methods@#The dietary survey data from 2012–2016 KNHANES was used. A total of 19,779 subjects (8,034 male [40.6%], 11,745 female [59.4%]) were classified based on gender, three age groups (19–29 years old [15.7%], 30–49 years old [46.9%], 50–64 years old [37.4%]) and three eating places (home, institution, and restaurants/convenient stores etc.). @*Results@#The portion sizes according to the eating places were calculated as per the median intake of Korean adults. Foods that showed the highest median intake in restaurants/ convenience stores were boiled rice and kimchi stew. The median intake quantity of kimchi stew was the highest in restaurants/convenience stores in men across most age groups.Women in 30–49 years age group also consumed a lot of kimchi stew in restaurants/ convenience stores. Men in the age groups 30–49 and 50–64 years consumed soybean paste stew the most in institutions compared to home and restaurants/convenient stores. Stir-fried pork was consumed the most at institutional meal places across all age groups. @*Conclusion@#The portion sizes of kimchi stew and boiled rice were the highest in restaurants/ convenience stores. As kimchi stew and soybean paste stew is high in sodium, the intake should be reduced in institutions and restaurants/convenience stores. Furthermore, it is necessary to reduce sodium intake through consumer nutrition education and the development of low-salt standard recipes for restaurants.

Immunoglobulin G4-Related Sclerosing Disease Manifesting as Bilateral Tonsillar Hypertrophy on MR Images: A Case Report

Immunoglobulin G4-related sclerosing disease (IgG4-SD) is currently recognized as a distinct systemic disease involving various organs. We reported the imaging findings of a case of pathologically confirmed IgG4-SD involving bilateral palatine tonsils. CT and MRI showed diffuse enlargement of both palatine tonsils with homogeneous contrast enhancement. Focal contour bulging was noted in the right palatine tonsil. Lesions appeared as isointense on T1-weighted and slightly hyperintense on T2-weighted MRI images, as compared with muscle. The T2-weighted MRI image showed a striated pattern in both tonsils. Despite its rare occurrence, IgG4-SD should be included in the differential diagnoses of patients with symptomatic bilateral tonsillar hypertrophy that is non-responsive to medication.

An Immunoglobulin G4-Related Sclerosing Disease of the Small Bowel: CT and Small Bowel Series Findings

Immunoglobulin G4 (IgG4)-related sclerosing disease is rare and is known to involve various organs. We present a case of histologically proven IgG4-related sclerosing disease of the small bowel with imaging findings on computed tomography (CT) and small bowel series. CT showed irregular wall thickening, loss of mural stratification and aneurysmal dilatation of the distal ileum. Small bowel series showed aneurysmal dilatations, interloop adhesion with traction and abrupt angulation.

The Association of Plasma HDL-Cholesterol Level with Cardiovascular Disease Related Factors in Korean Type 2 Diabetic Patients / 당뇨병

BACKGROUND: Cardiovascular disease (CVD) is the major cause of death in type 2 diabetic patients. The purpose of this study was to investigate the characteristics of Korean type 2 diabetes mellitus (DM) patients according to plasma high density lipoprotein (HDL) cholesterol level and to document the effect of diet on HDL-cholesterol. METHODS: The subjects were 252 (male: 134, female: 118) Korean type 2 DM patients recruited from a general hospital's DM clinic and divided into low HDL-cholesterol group (male or = 40 mg/dL, female > or = 50 mg/dL). Anthropometric and hematological variables and dietary intake were assessed by the groups. RESULTS: The subject's mean age was 60.2 +/- 1.1 years and duration of diabetes was 9.5 +/- 1.0 years. Anthropometric measurements (body fat mass, % body fat, WHR, fat free mass, and muscle mass) and BMI were not significantly different between two groups. The male subjects with low HDL-cholesterolemia showed higher Atherogenic Index (AI, P < 0.001) and higher % carbohydrate from energy than control group (P < 0.01). The female subjects with low HDL-cholesterolemia showed higher AI (P < 0.001) and a tendency of higher triglyceride level and lower intake of energy, protein, lipid, vitamin B1 and vitamin E (P < 0.05) than control group. CONCLUSION: The subject with low HDL-cholesterolemia showed significantly higher AI. Male subject with low HDL-cholesterolemia consumed higher carbohydrate and female subject with low HDL-cholesterolemia showed lower intakes of many nutrients. This result suggests the importance of an adequate and balanced diet to manage type 2 DM patients to prevent CVD complications.

Impact of Diabetes Duration on the Cardiovascular Disease Risk Factors in Korea Type 2 DM Patients

The purpose of this study was to investigate the impact DM duration on cardiovascular disease risk factors in Korean Type 2 diabetes mellitus patients. The subject were 250 (male: 134, female: 118) Korean Type 2 DM patients recruited from a general hospital's DM clinic. Anthropometric and hematological variables and dietary intake were assessed. The subject's mean age was 60.2 years and duration of diabetes was 9.5 years. As far as DM duration was concerned, male subjects with long duration (> or = 5 years and longer) showed significantly lower weight, fat free mass, skeletal muscle mass, BMI (p or = 5 years and longer) showed significantly higher fat free mass (p < 0.05) and skeletal muscle mass (p < 0.05), Hemoglobin A1c (p < 0.01), HDL-cholesterol (p < 0.01) and triglyceride (p < 0.05), dietary intakes of protein (p < 0.05) and fat (p < 0.05) compared to those with less 5years of duration. In conclusion, Type II DM patients of long duration had higher blood lipid concentrations and higher carbohydrates intakes. Subjects followed diet prescription strictly showed lower blood lipid concentration, suggesting the effectiveness of diet to manage Type 2 DM patients.

The Association of Insulin Resistance with Cardiovascular Disease Risk and Dietary Factors in Korean Type 2 DM Patients

The purpose of this study was to investigate the association between insulin resistance and cardiovascular disease risk factors in Korean type 2 diabetes patients. The subjects were 429 (male :218, female :211 )type 2 DM patients visited DM clinic, and they were classified into quartiles based on KITT index (%/min, Insulin Tolerance Test ). Anthropometric and biochemical characteristics, and dietary intakes by Food Frequency Questionnaire were assessed. The means of waist circumference, fat mass, percent body fat and abdominal fat thickness were significantly higher in the lowest quartile (the most insulin resistant group )than in the highest quartile (the least insulin resistant group )of KITT index (%/min )(p < 0.05 ). For hematological values, the lowest quartile showed significantly higher fasting blood glucose, HbA1c, C-peptide, insulin, triglyceride, ApoB/apoA-1 ratio and C-reactive protein compared to the highest quartile (p < 0.05 ). Moreover, KITT index (%/min )was negatively correlated with waist circumference, fat mass, percent body fat, abdominal fat thickness and fasting blood concentrations of glucose, HbA1c, C-peptide, insulin, cholesterol, triglyceride, ApoB/apoA-1 ratio and C-reactive protein (p < 0.05 ). Nutrient intakes were not significantly different among the quartile groups of KITT index (%/min )and also not correlated with insulin resistance, however, they showed correlation with obesity parameters (BMI, waist circumference, waist-hip ratio, vat mass, abdominal fat thickness ), which were strongly associated with insulin resistance. In conclusion, cardiovascular disease risk would be higher as the insulin resistance grows in Korean type 2 DM patients, and nutrient intakes would affect to the insulin resistance through the effect on anthropometric parameters.

Vascular Invasion of Klatskin Tumor: Computed Tomography vs Digital Subtraction Angiography in Determining Resectability

PURPOSE: To compare the accuracy of computed tomography (CT) with that of digital subtraction angiography (DSA) in predicting the resectability of Klatskin tumor on the basis of vascular invasion. MATERIALS AND METHODS: Twenty-five patients with Klatskin tumor who had undergone laparotomy were in-cluded in this study. In order to assess the surgical resectability of their tumors, the preoperative CT scans and DSA of these patients were retrospectively assessed in terms of vascular invasion. The criteria of unresectability were tumoral invasion of the proper hepatic artery or main portal vein, or simultaneous invasion of the hepatic artery on one side and the other side portal vein. RESULTS: Tumors were unresectable in 13 cases, and resectable in 12. CT and DSA predicted nine and three tumors as unresectable ones, respectively. The sensitivity, specificity, positive predictive value, negative predic-tive value and accuracy of CT in determining whether a tumor was unresectable were 61.5 %, 91.7%, 88.9 %, 6 8 .8 % and 76.0 %, respectively. For DSA, the respective figures were 23.1 %, 100 %, 100 %, 54.5 % and 6 0 .0 %. For the detection of vascular invasion without diameter change, CT was superior to DSA; for the evaluation of vascular anatomy, it was, however, less effective. CT failed to detect small hepatic metastasis (n=2), lymph node metastasis (n=1), variation of the bile duct (n=1), and the distal extent of tumor in the bile duct (n=1), factors which precluded surgical resection. CONCLUSION: CT is a reliable method for the detection of vascular invasion and tumor unresectability. For the detection of vascular anatomic variation, the combined use of CT and DSA would be helpful.

Comparison of In-Phase and Opposed-Phase FMPSPGR Images in Breath-hold T1-weighted MR Imaging of Liver

PURPOSE: To compare the effectiveness of the in-phase(IP) sequence and the opposed-phase(OP) sequence in the detection of focal hepatic lesions in the single breath-hold hepatic MR imaging with fast gradient T1-weighted pulse sequences. MATERIALS AND METHODS: If and OP T1-weighted breath-hold imaging was performed using fast gradient echo sequences in 45 patients referred for known focal hepatic lesions, in which 78 lesions were detected. There blind readers independently reviewed the images for lesion detectability. The signal-to-noise ratio(SNR) of the liver, the lesion-to-liver contrast-to-noise ratio(CNR) and the liver-to-spleen CNR were also compared. A consensus was reached by three readers to determine which sequence is better in image quality. RESULTS: On OP images, 61(78%), 61(78%), and 63(89%) lesions were correctly identified for reader 1, 2 and 3, respectively. On IP images, 66(85%), 65(83%), and 65(93%) lesions were detected for each reader, respectively. When two image sets were combined, 71(91%), 69(88%), and 76(97%) lesions respectively were detected for each reader. In cases of hepatocellular carcinoma, liver-to-lesion CNR was greater on the OP images(p<0.05), but in other lesions significant differences was not demonstrated. Liver-to-spleen CNR was higher in OP images(p<0.1), but the SNR of the liver was higher on the If images. CONCLUSION: Use of both If and OP imaging can be helpful to avoid erroneous missing of some focal hepatic lesions.

Comparison of the Success Rate of Recanalization According to Morphologic Patterns in Proximal Obstructed Fallopian Tube

PURPOSE: To compare the success rate of recanalization in three types of the proximal fallopian tube obstruction. MATERIALS AND METHODS: Transcervical fallopian tube catheterization (TFTC) was performed in 141 infertile patients with 239 fallopian tube obstruction. Three-coaxial catheter and 0.018 inch guide wire(Terumo, Tokyo, Japan) were employed for the recanalization. The obstructed proximal fallopian tubes were divided into three groups according to the appearance of the distal end of obstructed fallopian tubes : smooth tapering, concave, or convex. RESULTS: Recanalization was successful in 151 of 239 tubes(63.2%) ; success rates were 82.7%(62/75) in the smooth tapering group, 80.2%(69/86) in the concave, and 25.6%(20/78) in the convex. In theproximal portion, success rates were 80.3%(53/66) in the smooth tapering group, 82.6%(38/46) in the concave, and 48.5%(16/33) in the convex. Eighty-nine patients were successfully recanalized. Sixty-four of 89 patients were followed-up for more than one year and 29 patients(45%) became pregnant. Complications occurred in 37 tubes, tube perforation in 32, re-obstruction in five, and ectopic pregnancy in one. CONCLUSION: The success rate of recanalization of an obstructed proximal fallopian tube was higher in smooth tapering and concave types than inthe convex type.
