PURPOSE: To evaluate the radiologic findings and detectability of parathyroid masses in ultrasonograph computed tomography(CT), and radionuclide study(201TI-99mTc pertechnetate subtraction scintigraphy). MATERIALS AND METHODS: Surgically-proven 11 cases with parathyroid masses consisted of adenoma(n=8), adenomatous hyperplasia(n:2) and adenocarcinoma(n:l) were retrospectively analyzed. We performed US in all cases, CT in 8 cases, and radionuclide study in 7 cases. The parathyroid masses were analysed in regard to anatomic localization and imaging appearance on three modalities. RESULTS: Ten of the 11 parathyroid masses(91%) were located posterior to the thyroid gland and the remainder in the left superior mediastinum. Nine of the 11 cases(82%) were detected on US. The majority were well-defined hypoechoic mass on US. Six of the 8 cases(75%) were detected on CT scan. In the precontrst CT, all of the 8 masses were hypodense as compared with thyroid gland and most showed mild enhancement on post-contrast CT. Six of the 7 cases(86%) were detected on RI study as hot nodule. CONCLUSION: The typical radiological findings of the parathyroid mass were well-defined ovoid or round hypoechoic mass on US, hypodense mass with variable contrast enhancement on CT, and hot nodule on radionuclide study. US was a convenient and reliable imaging modality in detecting parathyroid masses. Improved diagnostic accuracy could be achieved with complementary CT scan and radionuclide study in addition to ultrasonography.

PURPOSE: To evaluate the ultrasonographic features of nonlactiferous breast abscess. MATERIALS AND METHODS: We retrospectively reviewed ultrasonograms of 21 cases with surgically and clinically proved nonlactiferous breast abscess. The cases included 17 cases of acute or chronic inflammation and 4 cases of tuberculosis. RESULTS: Location of the lesion was subareolar in 15 cases and peripheral in 6. Mean anteroposterior/transverse diameter ratio was 0.49. Internal echogenicitiy of the lesion was variable, with heterogeneous mixed-echoic echotexture in 18 cases and homogeneous hypoechoic in 3. Margin of the lesion was irregular in 18 cases(85.7%) and posterior sonic enhancement was observed in 17 cases(81%). There were also noted obliteration of adjacent superficial fascia, localized skin thickening, and sinus tract or ductal ectasia in 19(90.5%), 9 (42.9%), and 9(42.9%) cases respectively. CONCLUSION: Major ultrasonographic findings of nonlactiferous breast abscess was subareolar located, variable shaped mass with posterior enhancement. Additional findings were fistular formation, loss of superficial fascia, and axillary lymphadenopathy.

The purpose of this study was to investigate the effect of 3-month nutrition education (First Time Intervention, FI) + additional 3-month nutrition education (Repeated Intervention, RI) which was performed after the 8-month follow-up. FI was conducted during 0-3 months and RI for 11-14 months. Ninety-two subjects completed FI program, and 38 out of 92 subjects who received FI finished the RI. Anthropometric data, dietary assessment (24hr recall) and fasting blood analysis were measured at 0 month, 3 months, 11 months and 14 months time points. After FI (3 mo), waist circumference, triglycerides, total cholesterol were significantly decreased. At 11 month follow-up, body weight, BMI, hip circumference, SBP, DBP were significantly rebounced and HDL cholesterol was significantly decreased. Therefore, the effect of short-term nutrition education was not being sustained. After the secondary nutrition intervention (14 mo), waist circumference and hip circumference were again significantly decreased. Total diet quality index-international (DQI-I) score was significantly increased in both FI group and RI group. The changes in DQI-I scores were significantly correlated with the changes in body weight (r = -0.129, p < 0.05) and counts of nutrition education (r = 0.159, p < 0.05), indicating that effective nutrition education helps improve the diet quality leading to a possible role in CVD prevention among male workers. Although a short-term intervention seems to be a success, the effect was not retained in this study. Therefore, we suggest incorporating nutrition education as a routine program for male worker at worksite.

BACKGROUND AND OBJECTIVES: Practical concerns about transradial approach are increasing in consideration of high procedural success rate, low local complications, and patient's convenience. There was no available data about repeated-use of radial artery for coronary procedures. We evaluate the changes of radial arterial diameter and procedural outcomes of repeated transradial procedure. MATERIALS AND METHOD: Of consecutive 1771 transradial coronary procedures, 117 patients received repeated transradial procedures through the same radial artery. Radial arterial diameter, vascular access time and procedural outcomes were evaluated in between the group of first-use and repeated-use of radial artery. RESULTS: Among 117 patients of second transradial coronary procedure in the repeated-use group, 47 patients (41.6%) underwent coronary intervention and 66 patients (58.4%) underwent coronary angiography. The right radial approach was used in 82.9% of the cases. There was no significant difference in radial artery mean diameter between pre-procedure and 1 day after procedure in patients with first-use and repeated-use group. There was no significant change of radial arterial diameter after first-use depending on the SAR (the ratio of sheath outer diameter to radial artery inner diameter). However, after repeated-use of radial artery, there was significant reduction of radial arterial diameter 1 day after procedure in the patients with SAR more than 0.9 (p<0.05). In repeated-use group, the mean radial arterial diameter was 2.63 +/- 0.35mm mm before the procedure and 2.51 +/- 0.29mm during follow-up (136 +/- 123 days) (p<0.05). There was no significant difference of the vascular access time between the first-use and repeated-use procedures (2.9+/-3.1 vs 3.3+/-3.6 minutes, p<0.05). The procedural success and vascular complication rate of repeated-use of radial artery were as similar to those of the first-use, but total occlusion of radial artery was higher in the repeated-use group (2.6% vs 0.7%, p<0.05). CONCLUSION: The diameter of radial artery after transradial procedures was significantly reduced during follow-up and the incidence of asymptomatic radial artery occlusion was more frequent after repeated-use. However, repeated-use of radial artery was feasible in most patients with high procedural success rate and low vascular complications.

High selectivity provided by biomolecules such as antibodies and enzymes has been exploited during the last two decades for development of biosensors. Of particular importance are efficient immobilization methods for biomolecules in order to preserve their biological activities. In this study, we have evaluated immobilization strategies for an anti-DNA antibody on a self-assembled monolayer of omega-functionalized thiols. The antibody was immobilized via peptide bond formation between the primary amines in the antibody and the carboxyl groups on the self-assembled monolayer. The peptide bond coupling was achieved by activating COOH groups on the surface through N-Hydroxysuccimide (NHS)-ester formation, followed by acylation of NH2 group in the antibody. DNA binding activity of the immobilized antibody was examined by counting beta emission from 35S-labeled DNA.

PURPOSE: The purpose of management of the donor is to maintain a moist condition that promotes healing process and prevents pain, infection. We have performed a prospective study to compare the usefulness between Aquacel Ag(R) and Mepitel(R). METHODS: 36 consecutive patients, in whom STSG was performed, were included into the study. STSG are harvested as a usual manner and the donor site are dressed with Aquacel Ag(R) or Mepitel(R), alternatively. The usefulness are compared with re-epithelialization, pain, frequency to change the second dressing, and ease of application. RESULTS: There are no differences in the days of re-epithelialization, pain perception of patients, but significantly differences in frequency to change the second dressing, and ease of application. Aquacel Ag(R) is better than Mepitel(R). CONCLUSION: We concluded that Aquacel Ag(R) dressing is better than Mepitel(R) for STSG donor site just in the frequency to change the second dressing and ease of application.

Background and objective: With recent advances in technology and miniaturization of equipment, the trans-radial approach has currently been advocated as an alternative method for coronary angioplasty. We tried to evaluate the feasibility of trans-radial coronary intervention (TRCI). MATERIALS AND METHODS: 138 Allen-positive cases (159 lesions) underwent TRCI with currently available devices. Mean age was 60.8 + 9.2 years and 67% were men. Clinical diagnoses were AMI in 49, unstable angina in 48, stable angina in 28, OMI in 9 and 4 cases of restenotic lesions. RESULTS: Technical success was achieved in 124 cases (89.9%). Among the 124 successful cases, left and right radial arteries were used in 93 cases (110 lesions) and in 31 cases (35 lesions), respectively. The size of the guiding catheter used for TRCI was 6 Fr in 100 cases (80.7%), 7 Fr in 21 cases (16.9%), and 8 Fr in 3 cases (2.4%). Stent implantation and rotational atherectomy were successfully performed in 75 cases (86 lesions) and 10 cases (12 lesions), respectively. The reasons of failure were puncture failure in 2 cases, guiding failure in 6 cases, guide-wire crossing failure in 4 cases who had chronic total occlusion, and suboptimal results in 2 cases. Major cardiac complications occurred in 3 cases, one case of each cardiac death, nonfatal myocardial infarction and coronary artery perforation. No major entry site complications were seen with only non-ischemic radial artery occlusions in 3 cases (2.8%). CONCLUSION: TRCI is feasible with currently available devices and is safe with a relatively acceptable procedural success rate and low complications.

BACKGROUND AND PURPOSE: The radial artery has currently been regarded as a useful vascular access site for coronary procedures. We want to evaluate the incidence and clinical significance of anomalous branching pattern and tortuosity of radial artery. MATERIALS AND METHOD: From May 1997 to May 1999, retrograde radial artery angiography was performed in 1191 cases. Branching anomaly and tortuosity of upper extremity artery, procedure times and local vascular complications were analyzed. RESULTS: 1) Anomalous radial arterial branching was found in 3.2%. Most common one was high origin of the radial artery (2.4%). 2) Tortuosity of radial artery was found in 4.2%. Most common tortuosity were S shape in 1.8% and omega shape in 1.8% of cases. 3) Cross over to other artery, radial artery occlusion and perforation occurred in 24 cases, 6 cases and 4 cases, respectively. Prolonged procedure times, crossover to other artery and radial artery perforation was related with tortuosity of radial artery, not with anomalous branching. CONCLUSION: The incidence in branching anomaly and tortuosity of radial artery was not frequent in our study. Radial artery tortuosity was associated with old age, prolonged procedure time and radial artery perforation. In selected cases, pre- or intra-procedural angiographic assessment of radial artery might be helpful in performing safe procedure.
