Nowadays, the medical system towards patients changes into the medical services. As the human rights are improved and the capitalism is enlarged, the rights and needs of patients are gradually increasing. Also, based on this change, several systems in hospitals are revised according to the convenience and needs of patients. Thus, the cases of mobile portable among examinations are getting augmented. Because the number of mobile portable examinations in patient's room, intensive care unit, operating room and recovery room increases, neighboring patients are unnecessarily exposed to radiation so that the examination is legally regulated. Hospitals have to specify that "In case that the examination is taken out of the operating room, emergency room or intensive care units, the portable medical X-ray protective blocks should be set" in accordance with the standards of radiation protective facility in diagnostic radiological system. Some keep this regulation well, but mostly they do not keep. In this study, we shielded around the Collimator where the radiation is detected and then checked the change of dose regarding that of angles in portable tube and collimator before and after shielding. Moreover, we tried to figure out the effects of shielding on dose according to the distance change between patients' beds. As a result, the neighboring areas around the collimator are affected by the shielding. After shielding, the radiation is blocked 20% more than doing nothing. When doing the portable examination, the exposure doses are increased $0^{\circ}C$, $90^{\circ}C$ and $45^{\circ}C$ in order. At the time when the angle is set, the change of doses around the collimator decline after shielding. In addition, the exposure doses related to the distance of beds are less at 1m than 0.5m. In consideration of the shielding effects, putting the beds as far as possible is the best way to block the radiation, which is close to 100%. Next thing is shielding the collimator and its effect is about 20%, and it is more or less 10% by controlling the angles. When taking the portable examination, it is better to keep the patients and guardians far enough away to reduce the exposure doses. However, in case that the bed is fixed and the patient cannot move, it is suggested to shield around the collimator. Furthermore, $90^{\circ}C$ of collimator and tube is recommended. If it is not possible, the examination should be taken at $0^{\circ}C$ and $45^{\circ}C$ is better to be disallowed. The radiation-related workers should be aware of above results, and apply them to themselves in practice. Also, it is recommended to carry out researches and try hard to figure out the ways of reducing the exposure doses and shielding the radiation effectively.

Objectives : This study was performed to evaluate the clinical effect of acupuncture on microtraumatic injuries of the knee joint. Methods : Among the outpatients with knee joint pain who visited to Department of Acupuncture & Moxibustion, National Medical Center from February 2000 to September 2000, we selected 15 cases that showed normal finding in both X-ray and neurological examination, and that were categorized into microtraumatic injuries by the physical examination based on the Cyriax's orthopedic medicine. During acupuncture therapy, the patients were ordered to move involved side actively. The effect was assessed through questionnaires of CNRS(Cincinnati Knee Rating System). Results : We investigated 11 female and 4 male patients. The most common distribution of age was 30's(40%). The most commom duration of symtoms was from 3 to 5 months(40%). The most common microtraumatic injury was pes anserinus bursitis(33.3%), and followed by iliotibial band friction syndrome(20%), and patellar tendinitis(20%). In the CNRS, the mean number of before treatment was 60.6 and after was 66.5. 10 cases among the 15 patients were improved(66.6%). Conclusions : These results suggest that the acupuncture therapy combined with active movements of involved side was effective treatment modality on microtraumatic injuries of the knee joint.

Two cases of Eagle's syndrome are reported. The first case involved a 31-year-old man who complained of pain in his throat and pain at preauricular area on turning his head. Panoramic and computed tomography (CT) views showed bilateral stylohyoid ligament ossification. The symptoms were relieved after surgical removal. The second case involved a 56-year-old female whose chief complaints were a continuous dull pain and occasional 'shooting' pain on lower left molar area. During the physical examination, an ossified stylohyoid ligament was palpated at the left submandibular area. Panoramic and CT images showed prominent bilateral stylohyoid ligament ossification. CT scans also showed hypertrophy of left medial and lateral pterygoid muscles. The symptoms were relieved after medication. CT is a useful tool for the examination of ossified stylohyoid ligaments and studying the relationship between Eagle's syndrome and adjacent soft tissue.

Purpose of this paper is to extend help for clinical application in balloon cholangiography on patients who have undergone endoscopic sphincterotomy, impacted stones of intrahepatic duct, and missed bile duct because of other diseases in operating endoscopic retrograde cholangiopancreatography. This study was done for the patients who had clinical signs of biliary diseases from January to December In 1996. We studied 45 patients who had endoscopic sphincterotomy, re-examination after interventional treatment of the endoscopic retrograde cholangiopancreatography, and uncertain diagnosis due to common bile duct and intrahepatic duct those are not filled with contrast media. Balloon cholangiography was performed in case of uncertain diagnosis while operating endoscopic retrograde cholangiopancreatography. First of all, we insert balloon catheter Into the working channel of treatment jejunofiberscope and remove treatment Jejunofiberscope after ballooning, and lastly take biliary tract X-ray after Injection and changing position of patient. The results of this study were as follows. (1) In classification of diseases, stones of gall bladder, those of common bile duct, and those of intrahepatic duct were 30 cases, fistula was 1 case. (2) In total cases of 45, only diagnosis were 25 cases, interventional treatment were 20 cases. (3) In case of interventional treatment, endoscopic sphincterotomy and endoscopic nasobiliary drainage, and stone removal were about the same, 7, 7, 6 respectively. Balloon cholangiography will be useful to prevent patients from having repeated and unnecessary studies for the cases above explained. It is considered that this study will be useful for clinical application in terms of reducing medical expenses, pain while examination, and consultation hours.

This report presents the case of a 49-year-old man who presented with giant masses that had recently grown on the bilateral sides of the tongue. A clinical examination revealed rubbery yellowish lesions protruding from the tongue. A panoramic radiograph showed an enlarged soft tissue shadow of the tongue. Computed tomography showed well-defined circumscribed mass exhibiting a homogeneous low density on the bilateral sides of the tongue. On magnetic resonance images, the masses showed a high signal intensity on T1-weighted images and iso-signal intensity with partially hyperintense margin on fat-suppressed T2-weighted images. Surgical excision was performed, and a histopathologic examination confirmed the diagnosis of lipoma. The patient recovered well with no sign of recurrence. A giant lipoma is defined as a lipoma larger than 5 cm in diameter. A literature review of giant lipomas of the tongue is also presented herein.

Objectives: To demonstrate effective diagnostic method and proper management of recurrent thyroid cancer through to compare treatment and surveillance of $I^{131}$ scanning detected recurrence and clinically detected recurrence. Material and Methods: We retrospectively analyzed clinical information about 46 patients who has recurrent thyroid cancer of 298 patients who have been primarily operated due to thyroid cancer in PMC at the over 10 years between 1986 and 1995. We examine incidence of recurrence due to pathologic types, site of recurrence, disease free interval, detection method of recurrence, and also treatment and progression of recurrence. A patients in which the clinical examination was entirely negative and the $I^{131}$ scan demonstrated either a new area of $I^{131}$ uptake or an increased area of concentration, compared to the previous scan, was designated as a recurrence detected by $I^{131}$ scan only. Recurrences that were obviously by physical examination or chest x-ray, etc were considered clinically detected recurrence, regardless of the the results of the thyroid scan. Results: Mean of disease tree interval(DFI) is 36months. When mean DFI of $I^{131}$ scan detected recurrence is 28months, whereas mean DFI of clinically detected recurrence is 47months. In statiscal analysis, p-value is 0.043 as significantly. In progression of recurrent patient, NED is 28case, AWD is Sease, DOD is 13case. Among the 13case, scan detected recurrence is lease of 20 patients(5%), whereas clinically detected recurrence is l2case of 26 patient(46%). In statiscal analysis, p-value is 0.003 as significantly. Conclusion: Early detection of the recurrent thyroid cancer by $I^{131}$ scanning leads to good progress compare with detection by clinical examination. NED: No Evidence of Disease AWD : Alive With Disease DOD : Dead Of Disease DOC: Dead of Other Cause
