Author report a case of neurocysticercosis that involved the right cerebral hemisphere subcortically. The subject was 38-year-old Korean male. The headache, epileptiform seizures and left sided motor weakness were the symptoms. Simple skull X-rays showed no significant pathological findings. Right carotid angiogram disclosed the signs of a large mass in the centrosylvian region. CT scan also demonstrated large, multiple and round cystic lesions within the substance of the brain itself in the right frontoparietal region. At operation cyst wall and cysticercus in the fluid content of a mass were obtained. Postoperatively with the aids of occurrence of cysticercrus in the skin and positive serologic test, the diagnosis again confirmed.

PURPOSE: The pvrpose of this study was to evaluate the accuracy of radioactivity quantitation in Tc-99m SPECT by using combined scatter and attenuation correction. MATERIALS AND METHODS: A cylindrical phantom which simulates tumors (T) and normal tissue (B) was filled with varying activity ratios of Tc-99m. We acquired emission scans of the phantom using a three-headed SPECT system (Trionix, Inc.) witb two energy windows (photopeak window: 126 154 keV and scatter window: 101 123 keV). We performed the scatter correction with dual-energy window subtraction method (k=0.4) and Chang attenuation correction. Three sets of SPECT images were reconstructed using combined scatter and attenuation correction (SC+AC', attenuation correction (AC) and without any correction (NONE). We compared T/B ratio, irnage contrast [(T-B)/(T+B)) and absolute radioactivity with true values. RESULTS: SC+AC images had the highest mean values of T/B ratios. Image contrast was 0.92 in SC+AC, which was close to the true value of 1, and higher than AC (0.77) or NONE (0.80). Errors of true activity by SPECT images ranged from 1 to 11% for SC+AC, 22-47% for AC, and 2 16% for NONE in a phantom which was located 2.4cm from the phantom surface. In a phantom located 10,0cm from the surface, SC+AC underestimated by ?4%, NON.E 40%. However, AC overestimated by 10%. CONCLUSION: We conclude that accurate SPECT activity quantitation of Tc-99m distribution can be achieved by dual window scatter correc.tion combined with attenuation correction.

Bicoronal approach is adopted as an universal method for reduction and internal fixation of the fractured zygomatic arch in the treatment of complex zygomatic fracture. However bicoronal approach leaves many disadvantages, such as long incision, alopecia, prolonged edema, and paresthesia. Nowadays endoscopically assisted minimal invasive technique has been widespread not only for the aesthetic surgery, but also for the reconstructive surgical fields because of the benefits. We have been recently trying to apply endoscopic surgery to facial bone fracture surgery. Endoscopically assisted minimal invasive technique has been applied to 14 patients who admitted to Chosun university hospital from March 1996 to July 1997. We used 4 mm, 30' endoscope and two 1.5-2 cm temple incisions and a subciliary incision for approaching to the zygomatic arch. Protected drill bit and driver had access to fractured zygomatic arch though tiny(5 mm) stab incision over the zygomatic arch. We have been able to successfully reduce and make fixation of the fracture of zygomatic arch by using endoscopically assisted minimal invasive technique. Follow up for 3 months revealed good maintenance of the reduction. We think that application of the endoscopic technology to midfacial bone fracture will result in significant reduction in morbidity and improve postoperative results.

Recently, demand for minimally invasive surgery has increased greatly. As a result, robot-assisted techniques have gained in popularity, because they overcome several of the shortcomings of conventional laparoscopic techniques. However, robotic surgery may require innovations with regard to patient positioning and the overall arrangement of operative equipment and personnel, which may go against the conservative nature of anesthesia care. Anesthesiologists should become familiar with these changes by learning the basic features of robotic surgical systems to offer better anesthetic care and promote patient safety.

Purpose: This study was conducted to verify the effects of a physical activity program based on social cognitive theory for elderly women with knee osteoarthritis (KO). Methods: Ninety-two women aged over 75 with KO from one community center and five senior centers in G county participated. Groups of physical activity based on social cognitive theory (experimental, n=38), Thera-band physical activity (comparison, n=24), and no intervention (control, =30) participated in a 16-session, 8-week program. Results: Knee joint function, muscular strength, exercise self-efficacy, outcome expectations for exercise, social support, and social networks increased significantly in the experimental group compared to the other groups. Conclusion Physical activity based on social cognitive theory most effectively increased physical function, self-efficacy, and social support of elderly women with KO.

Fracture of the tibial shaft is one of the most common fractures of the long bones and frequently followed by malunion, delayed union and nonunion. We experienced the cases of further increase in the angulation after clinical union of the tibial shaft fractures treated by conservative method. So we analyzed 39 cases of tibial shaft fractures which were followed up from 12 weeks to 37 weeks after clinical union in adults. The results were as follows; l. 7 of the 39 cases(18%) showed the increase in the angulation, and all of them were male. 2. Increase in the angulation occurred more frequenlty in the comminuted fractures than simple fractures. 3. The increment of angulation was more marked in group of patients with higher angulation at the time of clinical union. 4. Increase in the angulation occurred more commonly in the cases not associated with fibula fracture than in the cases associated with fibula fracture. 5. Further increase in the angulation was less common in the cases in whom early weight bearing with PTB cast was started.

The courses of the progression in the fibrous dysplasia are characterized by asymptomatic progression or spontaneous regression in some cases after the growth has ceased and the aims of treatment for a fibrous dysplasia are prevention of the pathologic fractures and correction of the deformities. The osteogenic potentiality of the cambium layer in the periosteum and the beneficial effect on the osteogenesis of the impregnating bone graft with autologous red marrow are well documented. We experienced an extensive fibrous dysplasia with cortical thinning and pathologic fracture and it was managed with subperiosteal combined xenograft of Kiel bone with autologous red marrow for the induction of cortical thickening and prevention of the pathologic fractures because of the inoperability of curettage due to extensive lesion over the entire femur, limitations in obtaining large amount of autogenous cancellous bone for the graft and lack of the facilities of the bone bank. This subperiosteal composite xenograft with autologous red marrow for a fibrous dysplasia gave an excellent result of a remarkable cortical thickening and we think this can be a type of management for a entensive fibrous dysplasia. So we are reporting this case with bibliographic reviews.
