BACKGROUND: Some research viewed that effective dietary therapy was enough to control proper blood glucose level, but in the most patient, dietary therapy was not practiced and the most difficult part of managing their diabetes. The purpose of this research study was to investigate dietary practice adherence and perceived barriers among the elderly diabetes. METHODS: The survey was mailed to 852 persons with diabetes member via diabetic educator of 156 hospitals or clinics and 24 health centers. Questionnaire had background information of patients, meal regularity, food intake as a dietary practice adherence, barriers of 36 items which have 3 areas such as motive/attitude, knowledge, authority/resource. We asked the person with diabetes to rate barrier to dietary practice adherence. 432 questionnaire were returned the response. we selected 69 persons who were over 65 year old. RESULTS: 1) meal regularity was more satisfactory than food intake. 2) deficit of meal regularity were evening snack and resonable spacing between evening meal and evening snack. 3) deficit of food intake was serving of milk. 4) main barrier to dietary practice adherence was that of knowledge. CONCLUSION: For practice effectively dietary therapy to elderly diabetes, individual consultation or small group education must be pursued and more easily educational skills should be required.

PURPOSE: To assess the diagnostic usefulness of multimodality study in the diagnosis of breast cancer. MATERIALS AND METHODS: Eighty-one patients between January 1998 to December 1999 were involved in this study, and who underwent mammography, breast ultrasonography, and 99mTc-MIBI scintimammography in all cases the findings were retrospectively reviewed. Each modality was graded by two physicians specializing in nuclear medicine and two radiologists, all unaware of the pathologic results. A four-grade system(1=definitely benign, 2=probably benign, 3=probably malignant, 4=definitely malignant) was applied to those ofbreast ultrasonography and 99m Tc-MIBI scintimammography and BIRADS was applied to those ofmammography. All breast masses were confirmed by surgery (n=67) or FNA (n=14). Findings of grade 3 or 4 the four-grade system, BIRADS category 4 or 5, or positive coincidence in double and triple combination studies were defined as positive results, and on the basis of the data thus obtained, the sensitivity, specificity, positive and negative predictive value and diagnostic accuracy were calculated for each modality and for multimodality studies. RESULTS: The sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy of 99mTc-MIBI scintimammography were 83.6%, 88.5%, 93.9%, 71.9% and 85.2%, respectively. For ultrasonography, the corresponding figure were 94.5%, 65.3%, 85.2%, 85.0%, and 85.2%, and these for mammography, they were 87.3%, 69.2%, 87.3%, 81.8% and 80.2%. For the ultrasonography and mammography combination, the figures were 83.6%, 50.0%, 93.9%, 100.0% and 95.2%, respectively, and for 99mTc-MIBI scinti-mammography and mammography, the corresponding findings were 72.7%, 69.2%, 95.2%, 100.0% and 96.7%. For the 99mTc-MIBI scintimammography and ultrasonography combination, respective findings of were 80.0%, 61.5%, 95.7%, 94.1% and 95.2%, respectively, and in the triple modality study, respective findings of 70.9%, 50.0%, 97.5%, 100.0% and 98.1% were recorded. CONCLUSION: Among multimodality studies, sensitivity was greatest in the ultrasonography and mammography combination, which is thus extremely suitable for the diagnosis of breast cancer. The findings of two series suggest that in equivocal cases, 99mTc-MIBI scintimammography with its higher specificity and positive predictive value, is a useful adjunctive tool.

PURPOSE: To evaluate the anatomy of the hepatic artery and normal variants using oblique thick-slab maximal intensity projection (MIP) 3-D CT angiography and multidetector helical CT technology. MATERIALS AND METHODS: In 70 patients, axial three-phase CT together with multidetector helical CT and a non-ionic contrast agent was used to evaluate liver disease. During the early arterial phase, the parameters were as follow: slice thickness, 2.5 mm; table speed, 15 mm/rotation, pitch, 6; contrast material, 4 ml/sec; total 120 ml. Using the MIP technique and an Advantage window voxtal 3.03 system (GE), the images obtained were reconstructed as 3D angiograms. In each case, the arterial anatomy and its variants were recorded. RESULTS: A typical anatomy was found in 53 cases (75.7 %). Common variants were a left hepatic artery arising from the left gastric artery(8 cases, 11.4 %) and a right hepatic artery arising from the superior mesenteric artery(3 cases, 4.3 %). Other variant cases were a right hepatic artery arising from the gastroduodenal artery(2 cases, 2.9%), a proper hepatic artery arising from the left gastric artery (1 case, 1.4%), a hepatomesenteric trunk (1 case), a hepatogastric / splenomesenteric trunk(1 case), and a celiomesenteric trunk (1 case). CONCLUSION: 3-D hepatic angiography using multidetector helical CT technology is non-invasive and as accurate as conventional angiography for the evaluation of hepatic arterial anatomy. It is thus considered that 3-D CT angiography is very helpful for the evaluation of hepatic arterial anatomy prior to liver surgery such as transplantation or the treatment of hepatocellular carcinoma.

BACKGROUND: Increasing cigarette tax is known to be effective in stopping smoking and preventing initiation of smoking in adolescents. This study was designed to investigate the change of smoking attitudes in high school students after increase in cigarette tax in 2004. METHODS: A self-questionnaire study was performed in high school students in Seoul and Chungnam province in June, 2004. The number of respondents was 1,424 consisting of 883 males and 541 females. The factors related to smoking cessation or reduction of smoking amount after increase in cigarette tax were analysed. RESULTS: Among the total 1,424 subjects, 199 (14.0%) students smoked before the increase in cigarette tax. The smoking rate of males and females were 19.5% and 5.0%, respectively. Thirty nine percent of smokers quit smoking or reduced the smoking amount after increase in tax, among them 28.6% of the smokers (27.9% and 33.0% for males and females, respectively) reported quitting smoking. Female smokers and smokers in preparation stage of Prochaska model reported quitting smoking or reducing the smoking amount than male smokers and smokers in pre-consideration stage (OR 6.85:95% CI=1.78~26.33, OR 6.62:95% CI= 2.20~19.95, respectively). CONCLUSION: Increase of cigarette tax was effective in quitting the smoking and reducing the smoking amount in adolescents in Korea.

A 41-year-old female complaining of easy fatigue, headache, thickened extremities and deepened facial folds was admitted to the hospital. As early as 6 years ago, she had been told by family members that her voice was changed and both hands was thickened. Cranial plain radiography indicated ballooning of sella turcica. Sella MRI disclosed 2.2cm sized pituitary tumor with suprasellar extension. The pituitary tumor with hypothalamic extension was removed via a transsphenoidal approach. The postoperative course was uneventful until hyponatremia with sudden headache and respiratory arrest was developed. The case was due to hyponatremic encephalopathy on the basis of the clinical course and symptoms, and 3% hypertonic saline was infused for 12 hours until the hyponatremia was corrected. We have experienced a mortality case of hyponatremic encephalopathy in which surgieal removal of a pituitary tumor from a female acromegalic patient in menstruant period was followed by the sudden occurrence of hyponatremia, which in turn was later associated with marked brain edema.

BACKGROUND AND OBJECTIVES: QT dispersion (QTd) is defined as the difference between the maximum and minimum QT interval in any of the 12 leads of the surface ECG. QTd has been shown to reflect regional variations in ventricular repolarization. Ischemic dilated cardiomyopathy (DCM) may lead to more spatial and temporal dispersion in ventricular repolarization than idiopathic DCM. The purpose of this study was to determine the difference of QTd between patients who had ischemic and idiopathic DCM. MATERIALS AND METHODS: The study population included 30 patients with ischemic DCM and 30 with idiopathic DCM. All standard 12-lead ECGs were examined prospectively by two observers who were unware of the patient's details. RESULTS: QTd in ischemic DCM was significantly higher than that in idiopathic DCM (63+/-32 vs. 44+/-26 msec, p=0.012) and JTd in ischemic DCM was significantly higher than that in idiopathic DCM (48+/-21 vs. 36+/-22 msec, p=0.036). Results did not change when Bazett's QTc and JTc was substituted for QT (QTcd:69+/-33 vs. 52+/-28 p=0.039) and JT (JTcd:56+/-21 vs. 41+/-25 p=0.043). CONCLUSION: Ischemic DCM has increased spatial inhomogeneity of repolarization probably due to more regional myocardial damages compared with idiopathic DCM. The value of QT dispersion as an easily accessible, non-invasive method in predicting the risk of life threatening arrhythmia and overall mortality in patients with dilated cardiomyopathy must be confirmed in prospective trials.
