PURPOSE: To investigate the levels of radiation exposure of an operator which may be influenced by the wearing an apron, type of procedure, duration of fluoroscopy and operator's skill during various interventional procedures MATERIALS AND METHODS: Radiation doses were measured both inside and outside the apron(0.5mm lead equivalent) of the operator by a film badge monitoring method and the duration of fluoroscopy was measured in 96 procedures prospectively. The procedures were 30 transcatheter arterial embolizations (TAE), 25 percutaneous transhepatic biliary drainages (PTBD), 16 stone removals (SR), 15 percutaneous needle aspirations (PCNA) and 10 percutaneous nephrostomies(PCN). To assess the difference of exposure by the operator's skill, the procedures of TAE and PTBD were done separately by groups of staffs and residents. RESULTS: Average protective effect of the apron was 72.8%. Average radiation exposure(unit:micro Sv/procedure) was 23.3 in PTBD by residents, 10.0 in PTBD by staffs, 10.0 in SR, 8.7 in TAE by residents, 7.3 in TAE by staffs, 9.0 in PCN and 6.0 in PCNA. Average radiation exposure of residents were 1.9 times greater than those of staffs. CONCLUSION: Radiation exposure was not proportionally related to the duration of fiuoroscopy, but influenced by wearing an apron, various types o[procedure and operator's skills.

The pubic bone is an unusual site for an aneurysmal bone cyst. This case, a 15year old male patient, was diagnosed as an aneurysmal bone cyst in the superior ramus of the right pubic bone. He was treated by complete excision of the superior ramus and on five years follow up no problems were noted in terms of weight bearing as well as hip function or evidence of recurrence.

This dealt with the 23 cases of giant cell tumor of femur and tibia who were treated with curettage and cementation of the lesion, over 14 year period. Cement by virtue of it's heat of polymerization may “sterilize” the wall upto 3-5mm in depth. Authors adoped cement treatment as an effective adjuvant after intra-lesional surgery(curettage). Curettage was indicated in all stage I lesions; most stage 2 and some stage 3 lesions, provided the residual bone stock were sufficient to make it oncologically and mechanically effective. The follow-up period ranged from 3 to 14 years(oaverage 8 years and 6 months). The sites of the lesions were proximal tibia in 8, dital femur in 13, proximal femur in one, and distal tibia in one. Among these cases, 3(13.0%) cases(two grade 1 and one grade 2) of stage II(To: active), and 2(8.7%) of stage III(grade 2) (Tl or T2: aggressive). Utmost attention was paid to nulify or to reduce the local seeding of the tumor cell during aggressive curettage, which was followed by electrical cautery of the cavitey wall, and lastly by the cavity obliteration with bone cement. None of the cases had lung metastasis. Only in a stage III GCT case(4.3%) of local recurrence after curettage and bone and artificial bone graft, recurettage and cementation brought the successful outcome. Through this study, it was reconfirmed that with correct indications the use of cement as a local adjuvant in conjuction with curettage was effective method in treating GCT without any side effects.

A number of genetic and environmental factors influence athletic performance. Cardiovascular fitness is an important factor of athletic success, and ACE gene is a good candidate for regulating cardiac and vascular function. Because younger subjects have less chance of being exposed to environmental factors than older ones, genetic factors have a relatively greater influence on younger subjects. The aim of this study was to investigate the distribution of I/D polymorphism in the ACE gene between Korean young controls and athletes. By association study, there were no significant differences in genotype and allele distributions between two groups, respectively (P> 0.05). When stratified by sporting disciplines, the significant difference in distribution was not also detected in our study (P> 0.05). These results do not support the hypothesis that the I/D polymorphism in the ACE gene is associated with endurance performance in Korean young subjects.

PURPOSE: Ureter stones are the most common urological disease. The principal objective of this study was to evaluate the results, efficacy, and safety rates of laparoscopic ureterolithotomy for the treatment of large, upper ureteral stones. MATERIALS AND METHODS: Between April 2006 and February 2008, we conducted laparoscopic ureterolithotomy in 7 patients with upper ureter stones(L2-3). Laparoscopic ureterolithotomy was conducted in 5 patients as a salvage procedure after failed shock wave lithotripsy, in 1 patient as the primary procedure for a large stone(28mm), and in 1 patient for treatment of a radiolucent matrix stone. Laparoscopic ureterolithotomy was conducted via a transperitoneal approach. The mean stone size was 20.7+/-5.9mm. RESULTS: Laparoscopic ureterolithotomy was successful in 7 patients, and none of the patients required an open procedure. All patients were rendered stone-free after a single procedure. The mean operative duration, mean postoperative hospital stay, and mean estimated blood loss were 142+/-49 min, 6+/-2.2 days and 85+/-29.5ml, respectively. CONCLUSIONS: Although the majority of patients with ureter stones can be rendered stone-free via shock wave lithotripsy and endourological procedures, open surgery is required for large and upper ureter stones. In cases of large and upper ureter stones, laparoscopic ureterolithotomy may be considered for a limited group, although many will require open surgery.

PURPOSE: To evaluate the diagnostic accuracy and clinical utility of percutaneous needle biopsy of the bony lesions. MATERIALS AND METHODS: Among 100 consecutive patients who underwent percutaneous needle biopsy of bony lesions, 96 patients who were diagnosed ultimately by surgery, or by clinical and radiological follow-up over 6 months were reviewed in this study. Biopsy sites were in the long bones in 51, axial bones in 45. Twelve biopsies were performed under CT guidance and the remainder were guided under fluoroscopy. The categories for the suspected diagnosis included 25 primary malignant tumors, 21 benign tumors, 31 metastases, 13 infections, and 6 miscellaneous lesions. RESULTS: Of the 96 biopsies, 86(89.6%) were adequate for the diagnosis out of which 81 were ultimately confirmed as true-positive or true-negative with the overall diagnostic accuracy rate of 94.2%. Diagnostic accuracy according to the suspected diagnosis was 91.3% in primary malignant tumors, 90.3% in metastases, and 100% in infections, benign tumors, and miscellaneous lesions. Respective diagnostic yield was 90.3% in metastases, 84.6% in infections, 84% in primary malignant tumors, 71.4% in benign tumors, and 100% in miscellaneous lesions. Both diagnostic accuracy and diagnostic yield differed little with the lesion location. No complication was observed in our series. CONCLUSION: Percutaneous needle biopsy of bony lesion is a safe procedure, offering high diagnostic accuracy and high clinical utility.
