Positron emission tomography (PET) with 2-[F-18]-Fluoro-2-deoxy-D-glucose (FDG) was performed in ninteen patients who had benign musculoskeletal tumors in order to determine if there was a relationship between histologic grade of tumor and FDG uptake of tumor. These patients had been evaluated previously with computed tomography (CT) or magnetic resonance (MR) imaging or both. The diagnoses were confirmed with incisional or excisional biopsy or by radiographic follow-up. Generally high-grade tumors had significantly greater uptake of FDG than low-grade lesions . Benign lesions such as giant cell tumor, fibrous dysplasia, and osteofibrous dysplasia showed significant elevation of SUV (Standardized Uptake Value) above 4.0. On the contrary. The current studies suggest the utility of FDG-PET imaging as an adjunct to CT or MR imaging in the evaluation of benign tumors. And results of PET suggest benign tumors with high SUV are histologically active lesion and tend to be locally aggressive.

Cardiac rupture following blunt thoracic trauma is rarely encountered, since it commonly causes death at the scene. With advances in critical care, blunt cardiac rupture has been successfully treated with well-organized team approach including an emergency physician, anesthesiologist, and cardiac surgeon. We encountered a patient with blunt cardiac rupture of the junction of the superior vena cava and right atrium that extended 7 cm to the right ventricular junction. The patient was successfully resuscitated after a closed thoracostomy and pericardiocentesis with fluid loading. Cardiac injury was repaired via mid-sternotomy without cardiopulmonary bypass. The patient recovered without complications and was discharged on the 7th day after surgery.

Thirteen patients were operated for cubital tunnel syndrome and followed for an average of 26 months postoperatively. Ten patients had a history of relevant trauma and three patients had degenerative osteoarthritis of the elbow. The average duration of symptoms was 18 months (range, 2 to 96 months). Diagnosis was made by physical examination, electromyography and nerve conduction study. Among these, nerve conduction study was found to be the most valuable diagnostic method for the patients with atypical clinical findings. Most of the operations were performed by anterior transposition of the ulnar nerve. At the most recent follow-up, the result was excellent in two patients, good in eight, and fair in three; thus ten patients(77%) showed satisfactory results. The rating system for ulnar neuropathy based on sensory, motor dysfunction and pain was useful for evaluating the operative results. The postoperative gain of score for pain and sensory function were larger than that of motor function. Factors known to influence the result of the operation (age, duration of symptom, history of trauma, method of operation) did not effect the outcome in this study. For successful operation, the ulnar nerve must be thoroughly examined, all possible levels of compression must be released and new foci of compression must be created.

From February 1987 to December 1990, 654 patients with renal stones completed the multiple ESWL monotherapies using the EDAP-LT01 piezoelectric lithotriptor. The location of stones was calyx in 452 patients. pelvis in 1O8. calyx and pelvis in 94 and the stone size ranged from 0.6 to 4.8cm (mean 1.9cm). The number of treatment sessions was 2 to 19 sessions (mean 4.7) with 72.2% of re-treatment rate. In accordance with increment of stone size, number of treatment increased but success rate decreased; 2.8 sessions. 96.2% for 0.6-<1 cm. 4.4, 93.2% for 1-<2 cm, 5.5. 87.7% for 2-<3 cm. 6.3, 65.5% for 3-<4 cm and 6.4, 58.8% for stones larger than 4 cm. Supposing 654 patients had been completed by 5 sessions only. 67.9% of success rate would have been expected. But. 88.4% (578,654) of success rate was obtained by multiple treatment up to 19 sessions, adding 20.5%. Auxiliary ureteral manipulations were required in 88 (13.5%) patients and there were no significant complications. Therefore. multiple ESWL monotherapy is considered to be a efficient. safe procedure as the first applicable method for treatment of larger renal stones and to extend the indications of ESWL for renal stone.

PURPOSE: The purpose was to evaluate the procedure-related complications of the TIPS and its clinical significance. MATERIALS AND METHODS: The materials consisted of 52 patients who had 57 TIPS procedures for the management of variceal bleeding due to portal hypertension. To detect the occurrence of complications during transhepatic needle puncture(from hepatic vein to the portal vein), contrast material was injected with the withdrawl of the puncture needle. RESULTS: Procedure-related complications occurred in 28 patients (54%) among 52 patients. The corn lications were biliary tree puncture(15 cases), transperitoneal puncture(14 cases), stent malposition(3 cases) stent migration(1 case), hepatic arteries puncture(1 case), splenic vein perforation(1 case), and paroxysmal tricular tachycardia(1 case). Three patients had acute stent thrombosis with rebleeding immediately after procedure. The procedure was repeated in two patients. One patient was expired due to rebleeding. CONCLUSION: The procedure related complications were clinically insignificant in most instances, when stent thrombosis or proxysmal ventricular tachycardia was developed.

A total of 14 children underwent 29 treatments with EDAP-LT01 extracorporeal shock wave lithotripsy for urinary tract stones between February, 1987 and ugust, 1988. The results were obtained as follows : 1. The sex ratio was about A 2:1, 9 (64.3%) in male and 5 (35.7%) in female patients. The average patient age was 7.1 years with a range of 2 to 16 years. 2. Treated stone locations were kidney in 8 children (57.1% ) ; calyx in 6 (42.8% ) and renal pelvis in 2 (14.3% ) and ureter in 6 (42.9% ) ; upper ureter in 2 (14.3% ) and lower ureter in 4 (28.6 %). There were multiple renal stone in 4 (28.6% ) and bilateral renal stone in 1 (7.1%), the average stone size was 1.6cm with a range of 0.7 to 3.1cm. 3. The average numbers of treatment were 1.8 sessions and the average treatment time was 38.7 minutes. The average storage required was 107 in one session. 4. Of the 11 patients whose age was less than 10 years, 10 (71.4% ) required caudal anesthesia. Three patients whose age was more than 10 years treated without any type of anesthesia. 5. The total average success rate of treatment-ended 11 patients was 81.8% in stones of 0.7-3.0cm. The cause of failed ESWL were stone component in 1 and impacted stone in 1. 6. All or the patients were not required the pre and post-ESWL additional manipulation. ESWL complications were not required admission and surgical management. Therefore, we confirmed that EDAP-LT01 ESWL is a safe, effective and easily applicable technique for treatment of urinary stones in children.

EDAP-LT01 ESWL underwent 71 treatments in 20 patients with urinary stone of solitary kidney between February 25, 1987 and August 18, 1988. 1. The sex ratio was about 2:1, 13(65.0%) in male and 7(35.0%) in female patients. The average patient age was 50 years with a range of 23 to 65 years. The previous nephrectomy was owing to urinary tract stone in 19(95.0% ) and transitional cell carcinoma of renal pelvis in 1 (5.0%). 2. The duration of hospitalization was required from 2 to 7 days and the average post-ESWL stay was 1.5 days. 3. The treated stone locations were kidney in 18(90.0% ) ;calyx in 12(60.0% ) and renal pelvis in 6(30.0%) and ureter in 2(10.0%) ;upper ureter in 1(5.0% ) and lower ureter in 1(5.0%) There were multiple renal stones in 4(20.0% ).The average stone size was 1.6cm with a range of 0.7 to 4.1cm. 4. The average numbers of treatrnent were 2.7 sessions and the average treatment time was 30.2 minutes with a range of 17 to 42 minutes. The average storage was required 180 in one session. Of the patients, 4(20.0% ) were complained severe pain but treatment interruption or anesthesia were not required. 5. The success rate among 11 patients who completed ESWL treatment were 100.0% in 0.7-1.0cm, 60.0% in 1.0-2.0cm, 100.0% in 2.0-3.0cm and 77.8% in calyceal stones, 100.0% in renal pelvis stones. 100.0% in lower ureteral stones. Thus, the total average success rate was 81.8 %. 6. The method of pre-ESWL additional manipulation was used a upper ureteral stone 'push-up' in 1(5.0%). The post-ESWL additional measures were made in 4(20.0 % ) ;'push-up' & double -J stenting in 1(5.0% ) and double-J stenting in 3(15.0% ). The causes of failed ESWL were impacted stone in 1 and 'push-up' failure in 1. 7. None of the patients had significant changes in renal function by shock waves. ESWL complications were not required admission and medical management. Therefore, we confirmed that EDAP-LTOI piezoelectric ESWL is not influenced on renal function and is a safe, effective method for treatment of urinary stones in patients with a solitary kidney.

We investigated the 1,004 workers who worked in a automobile factory to study the epidemiologic characterist of dermatoses due to cutting oils. Among the workers, 667(66.4%) answered the questionnaire. They are belong to 5 departments of the factory-the Engine-Work(86), Power train Assembly(17). We measured the oil mist concentration in air of the departments and examined the workers who had dermatologic symptoms. The results were follows; 1) Oil mist concentration; Of all measured points(52), 9 points(17.2%) exceeded 5mg/m3-the time-weighed PEL- and one department had a upper confidence limit(95%) higher than 5mg/m3. 2) Dermatologists examined 213 workers. 172 of them complained any skin symptoms at that time-itching(32.5%), papule(21.6%), scale(15.7%), vesicle(12.5%) in order. The abnormal skin site found by dermatologist were palm(29.3%), finger & nail(24.6%), forearm(16.2%), back of hand(8.4%) in order. 3) As the result of physical examination, we found that 160 workers had skin diseases. Contact dermatitis was the most common; 69 workers had contact dermatitis alone(43.1%), 11 had contact dermatitis with acne(6.9%), 10 had contact dermatitis with folliculitis(6.3%), 1 had contact dermatitis with acne & folliculitis, and 1 had contact dermatitis with abnormal pigmentation. Others were folliculitis(9 workers, 5.6%), acne(8, 5.0%), folliculitis & acne(2, 1.2%), keratosis(1, 0.6%), abnormal pigmentation(1, 0.6%), and non-specific hand eczema(47, 29.3%). 4) The prevalence of any skin diseases was 34.0 per 100 in cutting oil users, and 13.3 per 100 in non-users. Especially, the prevalence of contact dermatitis was 23.0 per 100 in cutting oil users and 4.3 per 100 in non-users. 5) We tried patch test(standard series, oil series, organic solvents) on 49 patients to differentiate allergic contact dermatitis from irritant contact dermatitis and found 20 were positive. 6) In a multivariate analysis(independent=age, tenure, kinds of cutting oil), the risk of skin diseases was higher in the water-based cutting oil user and both oil user than non-user or neat oil user(odds ratio were 2.16 and 2.78, respectively). And the risk of contact dermatitis was much higher at the same groups(odds ratio were 5.16 and 6.82, respectively).
