PURPOSE: The study of the causative factors, surgical approachs and the clinical course of symptoms related to sciatic nerve injury after THR. MATERIAL AND METHODS: A retrospective review of 6 patients with sciatic nerve injury in 669 hips total hip arthroplasty during the period from Jan., 1986 to Dec., 1994. Each patient's record was reviewed with respect to age, sex, possible etiology, clinical course, surgical approach, treatment, and clinical condition at follow-up examination. RESULTS: ➀ The increased prevalence of nerve palsy was seen in revision surgeries(4 cases, 3.2%) compared to primary arthroplasty(2 cases, 0.4%) ➁ There was 2 cases(0.8%) of sciatic nerve injury in direct lateral approach and posterior approach, 4 cases(1%) ➂ Possible mechanisms of nerve injury included excessive soft tissue traction(3 cases), electrical thermal injury(1 case), Trochanteric fracture during femoral stem removal(1 case), and overlengthening of femur(1 case). ➃ The isolated peroneal division of the sciatic nerve was injured in 5 cases, and the both peroneal and tibial divisions were injured in one case. ➄ At a following period of 5 month, recovery of neurologic function was complete in con case, and two years follow up, 4 cases had a enough recovery of neurologic function(modified Sunderland scale 1,2). However, remained one case had a persistent severe weakness & dysesthesia at even 3 years follow-up. The prognosis for neurological recovery was related the degrees to which the nerve was damaged.

PURPOSE: To report a case of primary extramedullary plasmacytoma which is rare in the orbit. METHODS: A 72 year-old man was referred for the evaluation of a slowly developing proptosis in the right eye. A CT scan revealed the orbital mass which involved optic nerve and surrounding tissues. Incisional biopsy via lower lid was performed. RESULTS: Histopathologic examination confirmed the findings of plasmacytoma. Systemic evaluation including bone marrow biopsy, clinical and radiologic evaluation showed no evidence for multiple myeloma. Taken together we diagnosed the orbital lesion as a primary extramedullary plasmacytoma. He was treated with radiation therapy and followed for 6months without evidence of new lesion or systemic disease. CONCLUSIONS: We experienced a case of primary extramedullary plasmacytoma which is rare in the orbit. Continuing careful observation is warranted because of its variable natural course and prognosis.

Primary tumors of the heart are rare, and one-third of them are malignant. The most common malignant intracardiac tumor is angiosarcoma, which usually involves right atrium. MR features in one patients with right atrial angiosarcoma is presented and the literature briefly reviewed. Angiosarcoma demonstrated slightly heterogeneous intermediate signal intensity on T1-weighted images, high signal intensity on T2-weighted images and higher signal intensity on Gd-DTPA enhanced images. MRI provided more information regarding the extent of the tumor than 2D echocardiography or CT.

We report two cases of recurrent BCC in a 51- year-old woman and a 39-year-old woman which had been misdiagnosed aind treated as pigrnented nevi. Complete surgical resections were done followed by reconstruction using local rhombic transposition flaps. Final cosmetic results were excellent and no local recurrence was noticed during one year follow-up.

BACKGROUND: There is much harmful influence for health promotion when general publics and medical group misunderstand common health knowledge. Therefore we investigated the proportion of misunderstanding about health knowledge of general publics and medical group. METHODS: The data were collected via questionnaire which consisted of 30 questions (ll health behavior, 5 symptom, 14 treatment knowledge) quoted or revised on the basis of the book ('Misunderstood common health knowledge 100' published by humanism practice medical doctor association, 1994, hanwol company, South korea). The subjects were nonmedical group (third grade elementary school teachers and parents of students in Kyong ju city) and medical group (doctors-specialist, resident, intern, oriental doctor, medical student, nurse, assistant nurse in Kyong-Ju, Pohang city). The score was given 0 for false answer or no answer and 1 for true answer. RESULTS: The dominant subclasses of study subjects were as follows .Sex; female(352:64.5%)/age; 30-40 years old(318 persons : 58.5%) education ; high school graduate group(232: 42.8%)/job; nonmedical group(housewives, 168:36.2%), rnedical group(nurse, 67:36.2%). Medical group acquired higher total average score than non-medical group. There were no differences in the total scores about treatment, symptom, and health behavior in nonmedical group by job. In the medical group, doctors earned significantly higher score than other jobs. The average score per question was 0.53 in nonmedical group and 0.69 in medical group. Non-medical group received average score below 0.5 in 14 questions among 30 questions, while medical group received only in 5 items. CONCLUSIONS: Medical group acquired higher total average score than nonmedical group. Average score per question was 0.53 in non-medical group and 0.69 in medical group.

BACKGROUND: Acute abdominal pain is one of the most common problems in the family practice but the differential diagnosis of acute abdominal pain is difficult in first encounter. When family physicians are encountered with patients with acute abdominal pain in the ambulatory care settings, t,hey have to make a decision for management of acute abdominal pain such as admission, referral, discharge or follow-up without any definite diagnosis. If it is possible to predict the course or prognosis of acute abdominal pain by using certain data about patients, it will be helpful to make a decision for the management of acute abdominal pain. So we tested the hypothesis that acute abdominal pain with intermittent pain nature and normal simple abdomen X-ray finding is not serious and shows favorable outcome. METHODS: 126 patients with acute abdorninal pain were enrolled from Feb. to Aug. in 1995 at the emergency department of Kyungju hospital, Dongkuk University. 116 patients showed normal simple abdomen X ray finding and among them 94 patients were discharged and 21 patients were admitted. 92 patients were contacted in 1 week by phone call and they reported the outcome of their acute abdominal pain. RESULTS: Among 92 study populations, 44 patients were male and 48 patients were female. 72 patients complained intermittent abdominal pain and 21 patients complained continous abdominal pain. Frequencies of tentative diagnosis at emergency department were 45 acute gastroenteritis, 26 unknown, 14 functional gastointestinal disorders, 4 acute gastritis, 2 pelvic inflammatory diseases, and 1 ureter stone. Outcomes of patients with intermittent abdominal pain were more favorable than those with continous abdominal pain. CONCLUSIONS: If the patients with acute abdominal pain have intermittent pain nature and normal simple abdomen x ray finding, they will show favorable outcome and can be managed at ambulatory care settings.

BACKGROUND: Acute abdominal pain in children is one of the most common problems encountered in our daily practice. The children often are not able to tell us their exact complain symptoms and differential diagnosis of acute abdominal pain is difficult in its first encounter. When family physicians encounter patients with acute abdominal pain in the ambulatory care settings, they must make an appropriate decision for proper management such as admission, referral, discharge and follow-up without firm diagnosis. If it is possible to predict the course or prognosis of acute abdominal pain by clinical data concerning patient, it will be helpful to make a decision for the management of acute abdominal pain. So we tested for hypothesis that patients with acute intermittent abdominal pain and normal simple abdomen X-ray finding is not serious and shows favorable outcome. METHOD: 82 patients with acute abdominal pain were assessed from Oct. in 1996 to Sep. in 1997 at the emergency department of Kyungju Hospital, Dongkuk University. 69 patients among 82 showed normal simple abdomen X-ray findings. 67 patients were discharged and 2 patients were admitted. 64 patients were contacted by phone call after 1 week and reported their outcome of the previous abdominal pain. RESULTS: Among 64 subjects 36 patients were male and 28 patients female. 57 patients complained of intermittent abdominal pain and 7 patients complained continous abdominal pain. Positive predictive value of intermittent abdominal pain and normal simple abdominal x-ray was 98%. Outcome of patients with intermittent abdominal paln was more favorable than that of continuous pain. CONCLUSIONS: Acute intermittent abdominal pain and normal simple abdomen x-ray findings in children shows favorable outcome and can be managedim ambulatory care settings.
