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.

BACKGROUND: It has been well known that absolute and interpeak latencies of brainstem auditory evoked potentials (BAEP) are usually prolonged in diabetics. However, Its etiology is still controversial. We tried to identify whether the cause is structural or metabolic in origin by performing BAEP and brain MRI in the diabetic patients. METHODS: BAEP were performed in both the diabetic patients (DM) group (16 males and 15 females) and the normal control group (25 males and 33 female). A brain MRI was performed in the DM group on those who showed abnormal BAEP and com-pared the results of BAEP of the DM group with those of the control group. RESULTS: 7 patients (22.6%) showed abnor-mal BAEP (male; 6, female; 1, unilateral; 4, bilateral; 3) when abnormal BAEP was defined as being larger than two and a half standard deviations of the control group BAEP results. Two males of the DM group who showed abnormal structural lesions of the pons in their brain MRI were not included in the statistical analysis. The remaining 14 diabetic male patients (mean age: 58.7 +/-9.1 years, mean disease duration: 6.1 +/-4.7 years, mean hemoglobin (Hb) A1C: 7.7 +/- 2.0%) and 15 diabetic female patients (mean age: 60.6 +/-10.8 years, mean disease duration: 5.4 +/-5.1 years, mean HgA1C: 7.8 +/-2.1%) were stastistically analyzed. Interpeak latencies of I-III, III-V, and I-V were found to be signifi-cantly prolonged in the DM group. The prolongation of interpeak latencies of I-III and I-V were found to be signifi-cantly correlated with the disease duration only in the diabetic female patients, but not with age and HbA1c. CONCLUSIONS: These findings suggest that both metabolic derangement and structural lesion contribute to prolonging the central conduction time on BAEP pathway in diabetics.

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

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.

The decrease of bone density after fracture is a well-known phenomenon. Several studies of the changes of bone density after fracture demonstrated bone density decreased not only at the fracture site, b ut also along the whole fractured bone. Being treated with locked intramedullary (IM) nailing, 15 patients with the long bone fractures of lower limbs were examined by Quantitative Computed Tomography (QCT) or Dual-Energy X-ray Bone Densitometer (Lunar DPX-L) a few days after nail removal. In the cases of QCT (5 patients of the tibia shaft fracture), cortical bone density, cortical thickness and geometrical shape (i.e. external antero-posterior and medio-lateral diameters) of the fracture site were compared to those of the contralateral side. On the other hand, in the case of Lunar' (5 patients of the tibia shaft fracture & 5 patients of the femur shaft fracture), only cortical bone density was compared to that of the contralateral side. The results of this study were as follows: 1. When treated by the locked intramedullary nailing of the long bone fractures, the bone density of the tibia & femur shaft fractures measured from the fracture site, proximal and distal sites to mid-fracture decreased. 2. There was a difference in the bone density of the uninjured long bone diaphysis of the tibia & femur shaft fractures. That is, in the case of the tibia shaft fracture, the bone density of the ipsilateral femur diaphysis measured by QCT increased 2 %, and increased 7 % when measured by Lunar. But, in the case of the femur shaft fracture, the bone density of the ipsilateral tibia diaphysis measured by Lunar decreased 4%. 3. In the case of the tibia shaft fracture, the cortical thickness in the fracture site measured by QCT increased 72 %, and external antero-posterior and medio-lateral diameters increased 7 % and 63 %. It seemed to be the formation of peripheral callus due to medullary reaming preceding intramedullary nail insertion. Therefore, this clinical study demonstrated that the mechanical property of the long bone fractures was restored and restricted weight bearing hardly needs to recommended when the nail was removed after the fracture union. 4. The bone densities of the tibia shaft fratures measured by QCT were not different with those measured by Lunar.

Toxic effects of Aconiti tuber, an important ingredient of Chinese medicinal preparation, have been encountered clinically. The chief bioactive and toxic constituent is the alkaloid aconitine. In this study histopathologic changes in the fine structures of rabbit eye by intravenously administered aconitine were examined with light and electron microscopes. The initial and most characteristic features observed in the histopathologic study were degenerative changes in the myelinated nerve fiber layer. So the effects of aconitine on the rabbit eye were primarily regarded as toxic neuropathy.
