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.

In the East, Probably one of the most commonly performed esthetic operation is the piercing of the earlobes for earring. the complication of this procedure includes infection, the formation of the hypertrophic scar or keloid, and tearing. Keloid formation is one of the disaterous common complications of the ear piercing. the patients regard the keloid as a cosmetic blemish and they complain that they cannot wear earrings. We have experienced 5 patients of earlobe keloid complicated from piercing of the earlobes. We used intralestional steroid njection, in conjunction with surgical excision and pressure therapy for treatment of the keloid. Among various techniques for reconstructing a piercing, we chose modified Pardue's method for artificial earlobe cleft after wide excision of the keloid. the result was good and satisfactory without any complication after 4 to 24 months of follow-up. the purpose of this paper is to present a simple method of treatment of the earlobe keloid with preservation of the perforation for an earring.

The ultimate goal of diabetes education is to help patients with diabetes change their health- related behaviors and learn more about their condition. The development of programs resulting in long-term, independent behavioral change demands sustainable means for providing appropriate support and motivation and the availability of affordable and accessible resources. More diabetes education research is required to develop effective strategies that patients can successfully and continuously apply to daily life.

Qualitative research methodology is more recognized and valued in diabetes behavioral research in recent years. This paper reviews the trend of qualitative research about diabetes in Korea and abroad. In Korea, qualitative research is not common, especially for diabetes patients. Qualitative methods help clinicians answer questions that quantitative research may not be able to answer, such as exploring patient motivations, perceptions, and expectations. After reviewing the research in this area, it may provide motivation to researchers in Korea to perform qualitative research to increase understanding of diabetic patients' behavioral patterns.

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.
