PURPOSE: We performed this study to compare T1-201 and Tc-99m MIBI scans for the differentiation of malignant from benign breast mass. MATERIALS AND METHODS: Thirty-eight female patients underwent T1-201 breast scan and thirty-two of them also underwent Tc-99m MIBI scan of the breast. After intravenous injection of 74-111 MBq of T1-201, early (10 minutes) and delayed (3 hours) images were obtained. Then, 555-740 MBq of Tc-99m MIBI was injected and images after 30 minutes were obtained. We compared T1-201 and Tc-99m MIBI scans with pathologic RESULTS. RESULTS: Twenty-three patients were confirmed to have infiltrating duct carcinoma and fifteen patients to have benign breast mass by excisonal biopsy. The sensitivity of early and delayed T1-201 scan and Tc-99m MIBI scan in the detection of malignant breast lesion were 100% (23/23), 82% (18/22), and 90% (18/20), respectively. The specificity of early T1-201 scan was significantly higher than that of delayed T1-201 scan (p<0.05). The specificity of early and delayed T1-201 scan and Tc-99m MIBI scan were 73% (11/15), 73% (11/15) and 83% (10/12), respectively (p:not significant). Three patients out of nine with fibroadenoma and one patient with atypical duct hyperplasia were false positive in both early and delayed T1-201 scans. The size of fibroadenoma with false positvie in early and delayed T1-201 scan (4 cases) was larger than that of 11 fibradenoma with true negative scan (p<0.01). Metastatic axillary lymph node involvement was present in fifteen patients. The sensitive to detect metastatic nodes was 38% (5/13) for early T1-201 images, 15% (2/13) for delayed T1-201 images, 58% (7/12) for Tc-99m MIBI planar images and 67% (4/6) for Tc-99m MIBI SPECT. The sensitive of Tc-99m MIBI planar or SPECT was significantly higher than that of delayed T1-201 images (p<0.05). CONCLUSION: Early T1-201 and Tc-99m MIBI scan are useful noninvasive methods to differentiate malignant form benign mass of breast. Tc-99m MIBI scan was sensitive in detecting axillary lymph node metastasis in patients with brease cancer.

Myocarditis is defined as the myocardial inflammation caused by various infectious agents (such as virus, rickettsia , bacteria, protozoa, fungus and parasites). The clinical manifestations of myocarditis ranges from the asymptomatic state due to focal inflammation to fulminant fatal congestive heart failure secondary to diffuse myocardial involvement. Clinically, in some cases, it may simulate an acute myocardial infarction. We experienced a case of acute fulminant myocarditis that presented as acute myocardial infarction initially, and then progressed into and recovered from congestive heart failure and multiorgan failure.

PURPOSE: Our study aims to evaluate to evaluate clinical outcomes after cephalic vein transposition (CVT) to the axilla in patients with brachiocephalic arteriovenous fistula (BC-AVF) and cephalic arch stenosis (CAS). MATERIALS AND METHODS: Hospital records of 13 patients (median age, 61 years; males, 54%) who received CVT to the proximal basilic/axillary vein due to either dysfunction (n=2) or thrombosis (n=11) between January 2010 and February 2014 were retrospectively reviewed. RESULTS: Operation was performed under local anesthesia in all cases. There was no technical failure. Concomitant inflow procedure (banding or aneurysmorrhaphy) was performed in 5 patients (38%). During follow-up (1 to 50 months, median 17 months), 3 patients died with functioning AVF and one was successfully transplanted. Two patients suffered from recurrent symptomatic stenosis of AVF and received percutaneous balloon angioplasty. Another 2 patients experienced AVF occlusion treated with interposition graft and manual fragmentation. Overall primary, assisted primary, and secondary patency rates were 77.5%, 92.3%, and 100% at 6 months and 66.1%, 92.3%, and 100% at 1 year, respectively. CONCLUSION: Although most patients presented with BC-AVF occlusion, technical success and access patency rates after CVT were favorable compared with historical data for interventional treatment. CVT should be considered as an appropriate option in selected patients with CAS.

Necrolytic migratory erythema is a rare, distinctive, necrotizing cutaneous eruption usually associated with glucagonoma, an alpha-cell tumor of the pancreas. Other clinical features include ane- mia, diabetes mellitus and weight loss. However, it also occurrs without the pancreatic glucagonoma. So this rare condition is called pseudoglucagonoma syndrome, and has been described in association with chronic hepatic diseases, malabsorption with villous atrophy, chronic pancreatitis, celiac sprue, hypoproteinemia and odontogenic infection. We report a case of pseudoglucagonoma syndrome induced by malnutrition without glucagonoma. A 28-year-old Korean female was referred to our department complaining of multiple erythematous, desquamative, crusted and erosive patches on the extremities, and diffuse scalp alopecia for 5 years. She also had perianal erosion, angular cheilitis without glossitis, amenorrhea, axillary and pubic hair loss, and weight loss. Six years previously she had had Whipples operation for a pancreatic solid and papillary neoplasm. The laboratory data showed hypoalbuminemia, essential fatty acid deficiency, diabetes mellitus and slightly high levels of zinc and glucagon. A skin biopsy showed irregular acanthosis, epidermal edema and pallor, dyskeratosis, areas of superficial epidermal necrosis and vascular dilatation of the papillary dermis. The patient improved dramatically after intravenous hyperalimentation and oral intake of mediurn chain triglyceride. For 2.5 years she has taken medium-chain triglycerides without any other treatment, and no side effects on recurrence has been observed.

OBJECTIVE: Cartoons have been known to motivate learners and make learning process easier by combining verbal and visual effects. But they are mostly applied to motivate the less able learners, and have limits in delivering comprehensive information. Thus, more careful and scientific validation for the pros and cons of using cartoons for everyday use in various subjects is in need. METHODS: In this research, we used Electroencephalography(EEG) to compare cartoon learning and text learning by measuring four characteristic brainwaves including theta, alpha, sensory motor rhythms(SMR), and beta, from the left and right brain. The EEG signals acquired from 24 subjects are analyzed using the mean difference of the left and right brain and canonical correlation analysis. RESULTS: The theta brainwave of the left brain and right brain shows significant differences (p<0.05) from cartoon learning versus text learning in the theta brainwave while the other brain waves show similar patterns. CONCLUSION: Cartoon learning produced significantly stronger theta brainwaves than text learning implicating that cartoon learning reduces more focused attention, SMR brainwaves and beta brainwaves from the left brain explained cartoon learning and text learning process while alpha brainwaves explained those processes in the right brain.

In general. femoral neck fracture in young adult presents poor prognosis due to the high velocity injury, high angle shear fracture, and poor candidate for arthroplasty. In addition to the relative rarity of the injury, the high incidence of aseptic necrosis and nonunion have been reported in the management of these fractures. 25 cases of femoral neck fracture in young adult were treated with multiple pinning and analyzed at Sung-Ae general hospital from 1987 to 1994 after 28 months follow up in average with review of charts, X-ray and clinical result. There were 18 male and 7 female, 5 cases of them had significant polytrauma to other organs or skeletal system, authors tried to treat them as soon as possible to decrease the interval time between fracture and fixation (the average time was 39.7 hours.) Union occurred in all of Garden stage I (4 cases) and II (4 cases), but in Garden stage III (7 among 8 cases) and IV (7 among 9 cases) the union rate was lower. Average union time was 16.5 weeks. The incidence of complications (12%, 3 among 25 cases) was higher in displaced fractures group (Garden stage III, IV) and also in poorly reduced group of Garden’s alignment index. In conclusion, the prognosis of femoral neck fractures in young adult was related with mainly initial reduction and rigid fixation than the initial injury.

Gynandroblastoma is an extremely rare sex cord-stromal tumor with both female (granulosa cell tumor) and male (Sertoli-Leydig cell tumor) elements. Juvenile granulosa cell tumors are also very rare and are so named because they usually occur in children and adolescents. A 71-year-old woman with right upper quadrant abdominal pain visited our hospital. Pelvic computed tomography showed a large multilocular cystic mass, suspected to be of ovarian origin. We performed a total abdominal hysterectomy (total abdominal hysterectomy was performed) with bilateral salpingo-oophorectomy. A 13-cm multilocular cystic mass with serous fluid was observed in her right ovary. Upon microscopic examination, the solid component of the mass showed both Sertoli-Leydig cell and juvenile granulosa cell differentiation, which we diagnosed as gynandroblastoma. Gynandroblastoma with a juvenile granulosa cell tumor component is extremely rare and, until now, only six cases have been reported in the English literature. We report the first gynandroblastoma with a juvenile granulosa cell tumor component diagnosed in an elderly patient, along with a literature review.

BACKGROUND: ROKAF (Republic of Korea Air Force) Pilots are required to maintain optimal health status because of their job characteristics and importance as core forces. Their optimal health status can be achived by prac-ticing good health behavior. Therefore, this study tries to analyze the pilots' health behaviors for last 1 month and latest 12 hours before flight respectively, and to examine factors related to health behavior. The goal is to provide data for the development of more efficient nursing interventions. METHODS: In this study, 200 Air Force pilots was interviewed from Oct. 1 to Oct. 15, 2001. by the use of a structured questionnaire. Collected data was analyzed using SPSS Windows Version 10.0 for descriptive statistics, x2-test, Spearman's rho correlation. RESULTS: ROKAF Pilot's have good drinking and smoking habits and their alcohol drinking, smoking, dietary habits, sleeping hours is related to their Self-efficacy, perceived barrier, family support. Also, their before flight health behavior was not different largely their casual health behavior. CONCLUSION: In order to promote ROKAF Pilot's health status, programs should be designed according to age, aircraft types and marriage conditions, and strategies that enable to increase health behavior self-efficacy and to decrease perceived barrier should be employed.
