A Case of multifocal reticulum cell sarcoma in a 61 year old male is reported. The patient had multiple foci of sarcomatous lesion in the olecranon of the right ulna, medial candyle of the left tibia and in both ankle joints. His initial complaints on admission were pain and swelling in his both ankles and the right elbow of three months duration. Biopsy was carried out on his right ankle joint and diagnosis of reticulum cell sarcoma was made. Surgical excision of the right olecranon and below Knee amputation of the right lower extremity were performed. Following the surgical intervention, Cobalt 60 irradiation therapy was given for 20 days with total amount of 4,000 rads. The follow-up study three months after surgery revealed much improvement and no evidence of recurrence.

Fity-four patients with head and neck cancers were prospectively examined with the CT to determine its valuein staging cervical lymph nodes metastases and to compare with the clinical staging. The CT staging agreed withthe clinical staging in 61%(33/54), upgraded the clinical staging in 22%(12/54) and downgraded in 17%(9/54). Thepost-surgical confirmation was made in only 11 patients, The possible causes of disagreement between the CT andthe clinical staging, and the diagnostic value of the CT in the evaluation of the cervical nodes metastases werediscussed.

Gastric bezoars are large masses or concretions, composed with plant fiber, hair and miscellaneous foreign bodies, found in the stomach and occur usually as sequele of gastric surgery. We experienced 2 cases of fat bezoars which developed after drinking of melted beef fst. They had postprandial epigastric fullness and pain, those were relieved on supine and left recumbent position. Upper gastrointestinal series showed a large movable mass in the stomach in hoth cases. On gastrofibercopic examination, a large egg sized white bezoar was cordirmed in both cases and a gastrie ulcer at antrum associated in one case. In attempt to removal of the bezoars, we tried to break them, but failed because of its character. The patients were treated with pancreatic lipase containg digestives, Pancreon-F and Azintal. From one day after this treatment, symptoms were completely relieved. Five days later, we confirmed disappearance of bezoars by gastrofiberscopy. and upper gastrointestinal barium

Intramedullary nailing has become the most popular fixation method in the treatment of the shaft fractures of long bones especially of tibia and femur because it affords most rigid fixation of fracture via closed method which makes early rehabilitation possible. Nowadays intramedullary nailing of the humeral shaft is being performed by many surgeons with good results. Newer implants and better surgical techniques are being developed, which suggests application of this method can be widened. Purpose of this study was aimed to define whether intramedullary nailing could be an effective method or not in the treatment of humeral shaft fractures by documenting the practical points in the application of intramedullary nailing of humerus, effectiveness in fracture healing, any complications or obstacles. We managed thirteen humeral shaft fractures with closed locked intramedullary nailing with distal fanning devices(Seidel nail) from March 1993 to April 1994. Average follow-up period was 14 months(12 months-18 months). The results were as follows; 1, Union of the fracture was obtained at average 12.9 weeks(9 weeks-20 weeks) postoperatively except one case of nonunion, in which case, union was obtained at postoperative 10 months finally. 2. Among the 13 cases, painful limitation of shoulder motion remained in 6 cases. This complication was more common in the cases with protruded proximal end of the nail. Above results suggest that locked intramedullary nailing seemed to be one of the useful method in the treatment of the humeral shaft fractures. However, destruction and irritation of shoulder by the nail was found to be a grave problem, and we found that further investigations should solve this problem.

Nine patients of clinically definite multiple sclerosis (MS) were examined by magnetic resonance imaging (MRI) at 1.0T. The MS plaques were seen in the brain and spinal cord in eight and three patients. respectively. The frequent sites of MS plaques were periventricular white matter, brain stem, and cervical cord. The shape of most brain MS plaques was round or finger-like configuration. The MS plaques showed high signal intensity on R2 weighted images and low or iso signal intensity on T1 weighted images in all nine cases. Contrast enhancement was seen in 4 cases. Mild brain atrophy was noted in 2 cases and mass effect in 1 case. The sites of cord MS plaques in three patients were C2-C4, C2-C5, and C4-C6 levels respectively. The cord MS plaques showed high signal intensity on T2 weighted image and contrast enhancement on Gd-DTPA enhanced T1 weighted images in all 3cases with mild cord expansion in 2 cases. In conclusion, MRI is a useful diagnostic tool in evaluationg the MS plaques involving central nervous system.

Cancer tissues are characterized by increased glucose uptake. 18F-fluorodeoxyglucose(FDG), a glucose analogue is used for the diagnosis of cancer in PET studies. This study was aimed to compare the glucose uptake and glucose transporter l(GLUT1) expression in various human colon cancer cells. We measured FDG uptake by cell retention study and expression of GLUTI using Western blotting. Human colon cancer cells, SNU-C2A, SNU-C4 and SNU-C5, were used. The cells were incubated with 1micro Ci/ml of FDG in HEPES-buffered saline for one hour. The FDG uptake of SNU-C2A,SNU-C4 and SNU-C5 were 16.8+/-1.36, 12.3+/-5.55 and 61.0+/-2.17cpm/microgram of protein, respectively. Dose-response and time-course studies represent that FDG uptake of cancer cells were dose dependent and time dependent. The rate of FDG uptake of SNU-C2A, SNU-C4 and SNU-C5 were 0.29+/-0.03, 0.21+/-0.09 and 1.07+/-0.07cpm/min/microgram of protein, respectively. Western blot analysis showed that the GLUT1 expression of SNU-C5 was significantly higher than those of SNU-C2A and SNU-C4. These results represent that FDG uptake into human colon cancer cells are different from each other. In addition, FDG uptake and expression of CLUT1 are closely related in human colon cancer cells.

PURPOSE: This study describes the CT and MR findings of mucoceles occurred in the post-operative maxillary sinuses. MATERIALS AND METHODS: CT and/or MR of 19 maxillary mucoceles in 16 patients who had been operated by CaldwelI-Luc procedure were reviewed. CT scans were performed after contrast enhancement in axial and coronal planes with 5mm thickness. Three cases were studied with a 2.0 T or 0.5 T MRI, which demonstrated multi-compartment lesions. RESULTS: The lesions were bilateral in 3 cases. Compartmentalization of the antral cavity was seen in 7 out of 19 involved sinuses. Surgical bone defect of the anterior wall was the most frequent route of extension (11 cases) and extension into the infratemporal fossa with erosion of posterolateral wall was seen in 7 lesions. In 6 cases, the lesions involved orbit. The expansile and erosive bone changes were localized in every case. In one case with multi-compartment lesion, both T1- and T2-weighted MR images showed different signal intensities in each compartment which represented different protein concentration. CONCLUSION: Post-operative maxillary mucocele showed CT findings of localized erosion and bulging most frequently at the anterior wall in which the bone windows were made during the previous surgery. Post-operative compartmentalization of maxillary antrum may cause eccentric expansion of mucocete and each compartment may show different signal intensities on MR.
