PURPOSE: This study was performed to evaluate the diagnostic usefulness of double-phase Tc-99m MIBI parathyroidism scintigraphy with single photon emission computed tomography (SPECT) in patients with hyperparathyroidism. We also evaluated the relationship between Tc-99m MIBI uptake and oxyphil cell contents in parathyroid glands. MATERIALS AND METHODS: The subjects were 28 parathyroid glands of 10 patients who underwent Tc-99m MIBI parathyroid scintigraphy and parathyroidectomy for clinically suspected hyperparathyroidism. Early and delayed pinhole images were obtained at 15 minutes and 2 hours after injection of Tc-99m MIBI, and SPECT images were followed. The weight and oxyphil cell contents of parathyroid of tissue were obtained from pathologic specimen, and the scintigraphic findings were compared with histopathology. RESULTS: In surgical histopathology, 6 parathyroid adenomas and 9 parathyroid hyperplasias were confirmed. The sensitivity, specificity, and positive predictive value of early and delayed images were 46.7% (7/15), 76.9% (10/13), 70% (7/10) and 667% (10/15), 92.3% (12/13), 90.9% (10/11), respectively. SPECT image detected an additional small hyperplasia. The sensitivity, specificity, and positive predictive value of combined interpretation of early and delayed images with SPECT were 733% f11/15), 100% (13/13), 100% (11/11). The sensitivity was 100% (6/6) for aenoma, whereas that was 555% (5/9) for hyperplasia. Both adenomas and hyperplasias showed significantly increased oxyphil cell contents compared with normal parathyroid glands (p<0.0001), but the oxyphil cell content and weight were not significantly different between adenomas and hyperplasias. CONCLUSION: Double-phase Tc-99m MIBI parathyroid scintigraphy with SPECT is useful for lesion localization m patients with hyperparathyroidism. Although both adenoma and hyperplasia have increased oxyphil cell content, the sensitivity is high in adenoma, but low in hyperplasia.

Pyoderma gangrenosum is uncommon neutrophilic dermatosis characterized by richness of the mature neutrophilic polynuclear dermal infiltrate. Pyoderma gangrenosum is associated with variable diseases, most commonly inflammatory bowel disease, hematological diseases, malignancies, but it is reported rarely in rheumatoid arthritis. We report a case of pyoderma gangrenosum in rheumoid arthritis patient. A 50-year-old woman admitted to our hospital due to painful pretibial ulcerative skin lesions. She had been treated as rheumatoid arthritis for 8 years. At admission, body temperature was 36.5degrees C and other vital sign was unremarkable. Physical examination revealed right pretibial ulceration, multiple pustules on left pretibial area and both palms. Laboratory studies revealed WBC count 7,600/uL (neutrophils 60.3%, eosinophil 3.2%), hemoglobin 11.4 g/dL, platelet count 319,000/uL, ESR 65 mm/hour. Other lab findings were also unremarkable. Skin biopsy was done, which showed dense dermal infiltrate of neutrophils and wound culture were negative. By 8 weeks after systemic high dose corticosteroid (1 mg/kg/day), cyclosporine A (5 mg/kg/day), sulfasalazine 2 g therapy, symptoms and skin ulceration were being improved. Without skin relapse, she is followed up our hospital with low dose corticosteroid and sulfasalazine.

PURPOSE: The purpose of this study is to assess the patients satisfaction with a newly established video-monitor system and the associated basic items for performing breast ultrasound exams by conducting a survey among the patients. MATERIALS AND METHODS: 349 patients were invited to take the survey and they had undergone breast ultrasound examination once during the 3 months after the monitor system has been introduced. The questionnaire was composed of 8 questions, 4 of which were about the basic items such as age, gender and the reason of their taking the breast ultrasound exam, their preference for the gender of the examiner and the desired length of time for the examination. The other 4 question were about their satisfaction with the video monitor. The patients were divided into two groups according to the purposes of taking the exams, which were screening or diagnostic purposes. The results were compared between these 2 groups. The satisfaction with the video monitor system was assessed by using a scoring system that ranged from 1 to 5. RESULTS: For the total patients, the screening group was composed of 124 patients and the diagnostic group was composed of 225. The reasons why the patients wanted to take the examinations in the diagnostic group varied. The questionnaire about the preference of the gender of the examiner showed that 81.5% in the screening group and 79.1% in the diagnostic group preferred a woman doctor. The required, suitable time for the breast ultrasound examination was 5 to 10 minutes or 10 to 15 minutes for about 70% of the patients. The mean satisfaction score for the video monitor system was as high as 3.95 point. The portion of patients in each group who answered over 3 points for their satisfaction with the monitor system was 88.7% and 94.2%, respectively. CONCLUSION: Our study showed that patients preferred 5-15 minutes for the length of the examination time and a female examiner. We also confirmed high patient satisfaction with the video monitor system.

Purpose: Although both chronic kidney disease (CKD) and diabetes mellitus (DM) are considered factors increasing the risk of colorectal cancer (CRC), their impact on CRC is not fully understood. This study was aimed to investigate the impact of CKD, DM, or both diseases on the risk of CRC and to evaluate sex differences therein. Materials and Methods: Using data from the National Health Insurance Service–Health Examination Cohort in Korea, we conducted a 1:2 matched case-control study. The disease groups consisted of CKD-/DM+ (n=17700), CKD+/DM- (n=22643), and CKD+/DM+ groups (n=8506). After 1:2 matching by age, sex, and health examination year and month, the healthy control group consisted of 97698 individuals. Results: Multivariate Cox regression analysis showed that the CKD-/DM+, CKD+/DM-, and CKD+/DM+ groups were independently associated with an increased incidence of CRC, compared with controls [hazard ratio (HR), 1.34, 1.31, and 1.63, respectively; all p<0.001]. Compared to the controls, adjusted HRs for the cumulative incidence of CRC in the CKD-/DM+, CKD+/DM-, and CKD+/DM+ groups were, respectively, 1.32, 1.26, and 1.43 in male and 1.38, 1.39, and 2.00 in female. The HR for CRC incidence was significantly higher for the CKD+/DM+ group than for the CKD-/DM+ or CKD+/DM- group in female; however, this significant difference was not observed in male. Conclusion In female, having both CKD and DM significantly increases the risk of CRC, compared with having CKD or DM alone. This study suggests a significant difference in the effect of CKD or DM on the risk of CRC according to sex.

OBJECTIVES: Cancer stem cells are defined as focal cluster of cells within a tumor that possess the capacity for self-renewal and differentiation into phenotypically heterogeneous cells. Cluster of differentiation 44 (CD44) is considered one of the gastric cancer stem cell markers. We aimed to investigate how the expression of CD44 varies according to the clinicopathologic characteristics in gastric cancer. METHODS: For this study, 157 patients who received an operation due to gastric cancer between May 1998 and December 2009 were selected. CD44 immunohistochemistry was reviewed using the semi-quantitative scoring of intensity and proportion. The sum of the intensity and proportion scores was calculated, and a score of 2 or less was deemed ‘CD44-negative’ and 3 or more as ‘CD44-positive.’ RESULTS: Among the final 143 subjects, 69 (48.3%) were CD44 positive. Older age, intestinal type gastric cancer, lymphatic invasion, and lymph node metastasis were significantly correlated with expression of CD44. In the multivariate analysis, older age was the only independent factor associated with CD44 expression (P=0.028). CD44 expression was correlated with overall survival, 5-year survival, and disease-free survival. In the multivariate analysis, older age, male gender, and lymphatic invasion were independent predictors of poor overall survival. Also, older age and lymphatic invasion were significant factors in 5-year survival, and lymphatic invasion was an independent factor of poor disease-free survival. CONCLUSION: Older age (≥60 years) was independently associated with CD44 expression in gastric cancer patients. Also, CD44 expression was correlated with poor prognosis in gastric cancer patients.

PURPOSE: The aim of this study was to determine the allergenicity of soybean by fermentation. METHODS: Non-fermented soybean, fermented soybean by Bacillus subtilis KFCC 11293 and 3-step fermented soybean by Lactococcus lactis subsp. lactis IFO 12007 and Aspergillus oryzae and B. subtilis KFCC 11293 were extracted with phosphate buffered saline (PBS). In order to detect soybean-specific IgE, we performed SDS-PAGE and IgE immunoblot analysis by using 3 kinds of soybean extracts and sera from 9 patients with atopic dermatitis. All patients were sensitive to soybean, which were confirmed by CAP-FEIA. RESULTS: SDS-PAGE of non-fermented soybeans showed many bands, whereas only peptides of less than 15 kDa were found in fermented soybeans. IgE immunoblot analysis of fermented soybeans failed to detect specific IgE which were seen in non-fermented soybeans. CONCLUSION: Fermentation could reduce the allergenicity of soybeans by efficiently degrading antigenic proteins in soybeans. However, there was no significant difference between fermentation by B. subtilis and 3-step fermentation.
