188Re (beta=22 MeV; gamma=155 keV; T1/2=16.9 hours) is an attractive therapeutic radioisotope which is produced from decay of reactor-produced tungsten-188 parent (T1/2=69 days). 188W has been produced from the double neutron capture reaction of 186W. 188Re can be easily obtained by elution of saline on alumina based 186W/188Re generator, which is commercially available. Complexes labelled with 188Re have been developed for the radiotherapy treatment of diseases because of the desirable nuclear properties of the radioisotope and it's chemical properties similar to those of technetium, a well established diagnostic agent.

Traumatic dislocation of the hip presents serious problems that may lead to avascular necrosis, nerve palsy, post-traumatic arthritis even when reduction is promptly and adequately carried out. Among them avascular necrosis is the most important prognostic factor, so the early detection of this complication has critical significance for final result. Bone scan has been considered one of early diagnostic test, but recently MRI replaced its role for imaging in the detection of early AVN, treatment monitoring and prediction of prognosis. Authors prospectively studied the early finding of MRI to detect avascular necrosis of the femoral head and to predict prognosis in traumatic hip dislocation and fracture-dislocation. From December 1990 to November 1994, 12 case of dislocation and fracture-dislocation of the hip were studied . In follow up period ranging from 19 months to 65 months, 10 case had excellent or good result. All cases had abnormal MRI finding such as paraarticular edema, capsular bulging, joint effusion, femoral head fracture, but findings such as femoral head signal changes were dectected in only 3 cases. Among the 3 cases, 1 case had developed AVN and 2 cases were uneventful. Other complications were 3 cases of posttraumatic arthritis, 2 cases of incomplete sciatic nerve palsy, and 1 case of heterotrophic ossification. Although early MRI finding at posttrauma 2weeks gave less specific information, it could give good information for risk group and follow up control with more cases. Although it is expensive, MRI can be one of the most reliable reference in early diagnosis of AVN and prediction of prognosis in traumatic dislocation and fracture- dislocation of the hip with non-invasive method.

PURPOSE: To evaluate the prognostic significances of p53 and cathepsin D in the prostatic carcinoma, we compared them to other prognostic factors, such as nuclear grade and clinical stage. MATERIALS AND METHODS: The material consisted of 40 paraffin-embedded, primary prostate carcinomas. We examined the expression of p53 and cathepsin D using immunohistochemical staining and compared their expression with the grade and stage. RESULTS: The expressions of p53 were noted in the nucleus of tumor cells and cathepsin D were noted in the cytoplasm of tumor cells. Thirteen of 40 tumors were positive for p53. There were more expressing p53 in samples (40%) from prostatic cancer with a high Gleason score group than in samples (28%) from prostatic cancer with low Gleason score group. The expression of p53 was 22% in clinical stage B and C groups and 35% in clinical stage D group. These results showed that p53 expression was not statistically correlated with Gleason score and clinical stage, but there were trends to increased p53 expression with high Gleason score and progressed clinical stage (p>0.05). Progressed clinical stage group showed higher expression of cathepsin D than early clinical stage group. However, there were no statistical correlations between expression of cathepsin D and Gleason score, and clinical stage (p>0.05). CONCLUSION: These results suggest that the overexpression of p53 and cathepsin D may be associated with tumor differentiation and clinical stage, but have limited prognostic value in prostatic carcinoma.

Cerebral gigantism(Sotos syndrome) is a growth disorder that consists of large size at birth, rapid early growth rate with accompanying advanced bone age, acromegalic features, and developmental delay. Clumsiness in the absence of other abnormal neurologic findings is common. The cause is unknown. We report here a case of 238/12-year-old Sotos syndrome with final adult height above 97 percentile, abnormal brain MRI findings(large ventricles, prominent trigone, prominent occipital horn & thining of corpus callosum), clumsiness, and some behavioral problems.

A 65-year-old female, who suffered with a longstanding headache, was admitted to our hospital. MR imaging and digital subtraction angiography (DSA) demonstrated a vascular fat-containing mass in the right cerebellopontine angle. The lesion was surgically removed and the diagnosis of angiolipoma was established. The symptoms subsided after the operation.

PURPOSE: The aim of this study is to demonstrate the feasibility of 2-[fluorine-18] fluoro-2-deoxy-D-glucose (F-18-FDG) whole body scan (FDG W/B Scan) using dual-head gamma camera equipped with ultra high energy collimator in patients with various cancers, and compare the RESULTS with those of coincidence imaging. MATERIALS AND METHODS: Phantom studies of planar imaging with ultra high energy and coincidence tomography (FDG CoDe PET) were performed. Fourteen patients with known or suspected maligancy were examined. F-18-FDG whole body scan was performed using dual-head gamma camera with high energy (511 keV) collimators and regional FDG CoDe PET immediately followed it. Radiological, clinical follow up and histologic RESULTS were correlated with F-18-FDG finding. RESULTS: Planar phantom study showed 13.1 mm spatial resolution at 10 cm with a sensitivity of 2638 cpm/MBq/ml. In coincidence PET, spatial resolution was 7.49 mm and sensitivity was 5351 cpm/MBq/ml. Eight out of 14 patients showed hypermetabolic sites in primary or metastatic tumors in FDG CoDe PET. The lesions showing no hypermetabolic uptake of FDG in both methods were all less than 1 cm except one lesion of 2 cm sized metastatic lymph node. The metastatic lymph nodes of positive FDG uptake were more than 1.5 cm in size or conglomerated lesions of lymph nodes less than 1 cm in size. FDG W/B scan showed similar RESULTS but had additional false positive and false negative cases. FDG W/B scan not visualize liver metastasis in one case that showed multiple metastatic sites in FDG CoDe PET. CONCLUSION:S: FDG W/B scan with specially designed collimators depicted some cancers and their metastatic sites, although it had a limitation in image quality compared to that of FDG CoDe PET. This study suggests that F-18-FDG positron imaging using dual-head gamma camera is feasible in oncology and helpful if it should be more available by regional distribution of FDG.

Neonatal diabetes mellitus (NDM) is defined as hyperglycemia that presents clinical symptoms within the first month of life and requires insulin therapy to maintain euglycemia. The diabetic condition may be transient, permanent, or transient with recurrence later in life. NDM is a rare clinical disorder. Three cases of NDM have been reported in Korea so far. We experienced two cases of NDM in twin brothers who were born with small for gestational ages. Their HLA typings were DR9 and DR14, and insulin autoantibody, islet cell antibody, GAD-reactive autoantibody, and insulin receptor antibody were not found. The genetic analysis with polymorphic DNA markers for chromosome 6 indicated paternal uniparental isodisomy.
