Although the clavicle is probably the most commonly fractured bone, nonunions are rare. We experienced 19 cases of clavicle nonunions, trested at the Depatment of Orthopedic Surgery of Wonju Christian Hospital, between January 1980 and June 1988(seven years and six months). This study focused on predisposing factors in relation to nonunion of clavicle and treatment. The factors predisposing to nonunion were middle and lateral 1/3 of clavicle, primary open reduction, severe trauma with associated injury and persistent gross displscement of fregment. Among the 19 patients, 16 patients were treated with semitubular plating and iliac bone grafting, 2 patients with the resection of the distal fregment and one patient was treated with treated with K-wire fixation and bone graft. All patients achived good union by the postoperative 10.7 week on average and symptomes disappeared. It was concluded that symptomatic nonunion of the clavicle could be trested by operation, and the procedure of choice seemed to be rigid internal fixation with plate applied in compression and bone graft.

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: A retroperitoneoscopic adrenalectomy is theoretically the ideal procedure for an adrenalectomy. However, it is not popular due to its technical difficulty. Herein, we report our experience with retroperitoneoscopic adrenalectomies and describe the difficulties encountered during the operations. METHODS: From November 1996 to October 1999, a total of 41 retroperitoneoscopic adrenalectomies were performed. Forty (40) patients had a unilateral adrenal tumor (size: 1-6 cm): 21 aldosteronomas, 12 Cushing adenomas, 3 neurogenic tumors, 2 nonfunctioning adenomas, 1 vascular cyst, and 1 angiomyolipoma of the kidney. One (1) had bilateral hyperplasia. The operations were carried out in prone position in all cases with 3 trochars. RESULTS: Thirty five (35) operations were completed endoscopically. Five were converted to open procedures, and one was converted to a transperitoneal laparoscopic approach. The causes of conversion were 1 severe subcutaneous emphysema, 2 technical difficulties, 1 bleeding, 1 partial nephrectomy, and 1 missing tumor. The average operating time for the complete endoscopic adrenalectomies was 183 minutes in the first 14 cases and 142 minutes in the next 21 cases. There was no operative morbidity or mortality. The average hospital stay was 4.3 days in the first 14 cases and 2.8 days in the next 21cases. CONCLUSION: A retroperitoneoscopic adrenalectomy is a less invasive procedure than any other adrenalectomy procedure, and its only disadvantage is technical difficulty. However, the technical difficulty can be overcome with increasing experience.

Anaphylactic reaction during the perioperative period typically exhibits rapid onset, varying clinical manifestations, and an expected mortality rate of 1.5-9%. Neuromuscular blocking agents are the leading cause of perioperative anaphylaxis. Here, we report a severe case of anaphylaxis that developed in a 66-year-old man due to cisatracurium administration. And he was successfully managed by extracorporeal membrane oxygenation. Cardiopulmonary resuscitation was performed by extracorporeal membrane oxygenation, and the patient was successfully weaned off 24 hours later.

The authors conducted a clinical observation of 13 cases of pulmonary aspergilloma at Yeungnam University Hospital from March 1983 to March 1992, and the following results were observed: 1) The male to female ratio was 1 : 1.2, and the age distribution was ranged 30 to 67 years old. 2) All cases were symptomatic : hemoptysis, cough, sputum and dyspnea. Especially, hemoptysis was the presenting compliant in 10 patients (77%) 3) The underlying lung disease were pulmonary tuberculosis in 9, COPD in 5 and bronchiectasis in 2. 3 cases were without underlying disease. 4) According to radiographic appearance, 8 cases had the typical crescent sign and 5 cases were seen nodular lesion. And the lesions of 11 cases were located in both upper lung. 5) 10 cases were treated with surgical resection. Among these cases, 8 cases were alieved and 2 cases, died. And other 3 cases were treated with conservative treatment. We suggest that these findings would be helpful for the diagnosis and treatment of pulmonary aspergilloma and further study might be needed to evaluate the prognosis of pulmonary aspergilloma.

Examination is indispensable to medical education. It qualifies medical education, drives medical students to study hard, and provides guides for the students acquiring a large amount of medical knowledge. This study provides an approach to organize the question pool for medical examination. In this approach, many questions in the form of HTML based texts were stored and managed in text-and memo-type field of Microsoft Access database system. They could be retrieved from the database in computer-generated HTML file, which could be read in word processors and web browsers. Several advantages of HTML bases text were emphasized. Though they are essentially text format data which can be stored and processed easily in text-type field of databases, they don't lose character attributes such as bold, italic, underlined, superscript, subscript and so on. Also they can provide table facility and links to external graphic files. This approach can be applied in other medical information retrieval system.
