PURPOSE: The aim of this study was to investigate the diagnostic role of 99mTc-Tetrofosmin in detection of breast cancer and compared with that of 99mTc-MIBI. MATERAL AND METHODS: Forty-eight patients with a clinically palpable mass or abnormal mammographic or ultrasonographic findings had 99mTc-MIBI and 99mTc-Tetrofosmin scintimammographies after intravenous injection of 925 MBq of radiopharmaceuticals. The scintimammographs were correlated with histopathologic findings. RESULTS: Thirty-three patients were diagnosed with breast cancer and 15 patients with benign breast diseases. The numbers of true positive, true negative, false positive, and false negative cases of 99mTc-MIBI scintimammography were 29, 10, 5, and 4 respectively. The sensitivity, specificity, positive predictive value, and negative predictive value of 99mTc-MIBI scintimammographies were 87.8%, 66.7%, 85.3%, and 71.4% respectively. The numbers of true positive, true negative, false positive, and false negative cases of 99mTc-Tetrofosmin were 31,10, 5, and 2 respectively. The sensitivity, specificity, positive predictive value, negative predictive value of 99mTc-Tetrofosmin were 93.9%, 66.7%, 86.1%, and 73.3% respectively. One patient was false negative in both 99mTc-MIBI and 99mTc-Tetrofosmin scintimammographies and its size was 0.5cm. CONCLUSION: 99mTc-Tetrofosmin and 99mTc-MIBI were non-invasive and useful in detection of breast cancer and 99mTc-Tetrofosmin was comparable to the 99mTc-MIBI in detection of primary breast cancer.

PURPOSE: Tc-99m MIBI scintimammography has been validated as an useful non-invasive diagnostic tool for the primary breast cancer. But most studies have included small population of patients. We have experienced a large study population and investigated the diagnostie usefulness of Tc-99m MIBI scintimammography in detection of primary breast cancer and axillary Iymph node metastasis. MATERIALS AND METHODS: This study included 30S patients who underwent scintimammography for palpable breast masses or abnormal radiologic findings. Tc-99m MIRI scintirnammography was performed 10 minutes after intravenous injection of 925 MBq of Tc-99m MIBI. If the early image revealed abnormal finding, 3 hour delayed image was also acquired. We calculated early and delayed lesion to non-lesion ratios (L/N). The pathologic diagnosis was obtained from surgical operation or F.4AB and compared with the results of Tc-99m MIBI scintimammography. RESULTS: Malignant breast diseases were 155 and benign ones were 150. Tc-99m MIBI scintimammography revealed 132 true positive, 23 false negative, 10 false positive, and 140 true negative cases. The sensitivity, specificity, positive predictive value and negative predictive value for the primary breast cancer detection were 85.2%, 93.4%, 92.9%, and 85.9%, respectively. The sensitivity, specificity, positive predictive and negative predictive values of Tc-99m MIBI scintimammography in detecting metastatic axillary lymph node involvement were 22%, 90.4%, 61.9% and 62.3%, respectively. Early L/N of malignant breast disease was significantly higher than that of benign one (2,44+/-0.97 vs 1.94+/-0.78, p=0.01). Delayed L/N had no significant difference between malignant an Breast Diseases ; Breast Neoplasms* ; Breast* ; Diagnosis ; Humans ; Injections, Intravenous ; Lymph Nodes ; Neoplasm Metastasis ; Sensitivity and Specificity

The widespread use of diagnostic radiography, especially using magnetic resonance imaging, has helped to increase the diagnosis of paralabral cysts in patients with chronic shoulder pain. These paralabral cysts are frequent in the anterior, the superior, and the posterior compartment of the shoulder joint but are rare in the inferior compartment. Paralabral cysts in the shoulder appear particularly in men in their third and fourth decades but rarely in elderly patients. We report a case of an inferior paralabral cyst in an elderly patient whom we treated through arthroscopic decompression.

Object: To treat hydrocephalus by ventriculo-peritoneal shunt operation, the correct positioning of the proximal catheter in the ventricle is very important. The purpose of this study was to develop the "shunt guiding kit" for the proper positioning of the proximal shunt catheter to the ventricle in the ventriculo-peritoneal shunt operation. MATERIALS AND METHODS: The "shunt guiding kit" is made of tungsten alloy and it consists of one frame, two screws and one guider. Through the guider, the proximal shunt catheter operates by mechanically coupling the posterior burr hole to the anterior target point. RESULTS: We have treated three hydrocephalus patients with use of the "shunt guiding kit", and achieved good location of proximal shunt catheters. CONCLUSION: We developed the "shunt guiding kit" for the proper positioning of the proximal shunt catheter to the ventricle, and this would be very useful for preventing ventriculo-peritoneal shunt malfunction and preventing possible brain injury during the procedures.

PURPOSE: Intrahepatic duct stones have been known to be a benign disease but because of the associated serious complications and the high recurrence rate, the management of the hepatolithiasis is very difficult. This purpose of this study was to classify the patterns of intrahepatic duct stones, and to evaluate the effect of surgical treatment according to their type and the residual stones that were present. METHODS: The clinical records of 212 patients who underwent a hepatic resection or drainage procedures between January 1988 and December 2000 were reviewed. RESULTS: We classified the intrahepatic duct stones as being either a localized simple type, a localized complicated type, a diffuse simple type, or a diffuse complicated type. Hepatic resections were performed in 177 (83.5%) cases. Among these we performed a hepatic resection along with drainage procedures in 41 cases (19.3%). In 35 (16.5%) cases, only drainage procedures were performed. Of a total of 25 cases of postoperative residual stones (25 cases), 13 (52%) cases were removed completely or partially by choledochoscopic procedures in 13 (52%) cases and in 15 (60.0%) cases they were removed completely or partially by spontaneous drainages. CONCLUSION: Our conclusions were that the, localized type of the IHD stones were treated successfully by a hepatic resection and the localized complicated type and the diffuse type IHD stones were treated effectively by hepatic resection and drainage procedures which reduced the opportunity for residual stones to develop following an accurate preoperative diagnosis of the location of the stones. Therefore, treatment methods should be individualized for each type of stone and by surgical treatments that combine endoscopic and resolution methods.

Eosinophilic granuloma, Hand-Schuller-Christian and Abt-Letterer-Siewe syndrome are known to be the same disease entity involving the reticulohistiocytic system of the body, although their clinical manifestations are different. So they were included under the term of Histiocytosis X and this concept has been generally accepted. The authors have experienced one case of Hand-Schuller-Christian disease and that of eosinophilic granuloma. The former was a 23 years old man with complaints of exophthalmos, polyuria and a tender palpable mass on the right parietal area and in the latter a soft pulastile mase located on the left parietal area in a 3 year old boy. There was no neurological deficits on their admission. We managed them with radiation and steroid therapy following surgical curettage.

OBJECTIVES: The purpose of this study was to examine the automatic attentional bias to disease/body-related stimuli in individuals exhibiting somatization tendencies using Event-Related Potential (ERP). METHODS: The participants were classified according to somatization and control groups based on the somatization symptom scales of the Symptom Checklist-90-Revised and Somatosensory Amplification Scale scores. ERP were recorded in the somatization and control groups while participants were performing the task to respond with neutral (standard stimuli) or disease/body-related words (target stimuli). We compared N100, P200, and P300 ERP components between the two groups. RESULTS: In the somatization group, the reaction times to disease/body-related words were faster than for neutral words. In ERP analysis, N100 to standard stimuli was not observed in the somatization group. The somatization group showed higher P200 and P300 amplitudes to target stimuli than standard stimuli. On the contrary, in the control group, no difference in P200 and P300 amplitudes was observed between target and standard stimuli. CONCLUSION: It is suggested that individuals exhibiting somatization tendencies have automatic attentional bias to disease/body-related stimuli and interpret disease/body-related stimuli as self-relevant stimuli.
