The accidental swallowing of foreign bodies by infants and children is a common problem. The proper methods of therapy must be carefully selected according to the age of the patient, the type of forei gn body, the location of impaction, the duration of ingestion, and the available medical resources and skills. This report reviews 41 cases of ingested foreign bodies in the upper GI tract at the Department of Pediatrics, Yonsei University College of Medicine between January 1981 and June 1991. The results were as follows: 1) The ages ranged from 3 months to 13 years with 34 cases less than 5 years of age, 5 cases between 5 to 10 years of age, and 2 cases greater than 10 years of age. 2) The male to female ratio was 1.9:1 with 27 male and 14 female patients. 3) The types of ingested foreign bodies were coins in 15 cases(36.6%), pins in 9 cases(22.0%), rings in 3 cases, food in 3 cases, nails in 2 cases, and others. 4) presenting symptoms were varable with vomiting in 8 cases(19.5%), coughing in 4 cascs(9.8%), dysphagia in 4 cases(9.8%), poor oral intake in 2 cases(4.9%), diarrhea in 2 cases(4.9%), and others. 5) Ingested foreign bodies were located in the esophagus in 14 cases(34.2%), stomach in 24 cases(58.5%), duodenum in 1 cases(2.4%)and uncertain locations in 2 cases. 6) Methods for the removal of ingested foreign bodies included 15 cases of endoscopic removal(53.6%), 1 surgical removal (3.6%), and 12 spontancous removals(42.8%). 10cndoscopic removals were carried out in 12 esophageal cases(83.3%), but 10 out of 16 stomach cases were removed spontaneously (62.5%). 7) Duration from ingestion to removal of foreign bodies renged from 19 hours to 2 years. All 12 spontaneous removal cases were within 2 weeks, and 1 surgical case was performed 2 years after ingestion. 8) Endoscopic findings of patients with esophageal foreign bodies included 3 normal cases(30.0%)and 7 moderate to severe abnormal cases(70.0%), and those patients with gastric foreign bodies included 3 normal cases(60.0%)and 2 mild superficial mucosal lesion cases.

Twenty-seven patients with congenital constriction band syndrome were treated at department of orthopedic surgery, college of medicine, Seoul National University between 1981 and 1989. In order to obtain basic and fundamental information about this syndrome, we have analyzed the clinical records of those patients who were treated at our hospital with above syndrome. Analysis was based on the age at operation, sex distribution, familial history and past-medical history, prevalent sites of constricition bands, associated anomalies and methods of surgical treatments. The results were summarized as follows: l. Average age at operation was 9.3 months and the ratio of sex was 3:2 as male predominant. 2. There was no case with familial history of this syndrome, and serious medical problems of patient's mothers during pregnancy were not experienced except 4 cases who took some medication for URI. 3. The frequency of constriction band was greater distally than proximally, and 91% of these bands were noted distal to knee and elbow joint. 4. About 85% of cases were associated with other anomalies, and among them syndactylism and acral absence were most frequent. 5. For the simple constriction ring, staged excision of the ring and z-plasty of the defects seemed to be a most agreeable recommendation. And other associated anomalies of digits could be treated with combined procedures such as seperation of digits, web construction, transposition of ray, lengthening of digit, skin graft, corrective osteotomy, etc.

Since 1954 when the first biodegradable polymer, polyglycolic acid(PGA), was synthesized, many different biodegradable and tissue-tolerant materials have been invested and studied for internal fixation devices. The use of biodegradable materials for the internal fixation of fractures would avoid the need for later removal of the implant. However, problems of a physical and chemical nature have delayed the development of biodegradable implants applicable to fracture management. The authors reviewed 17 cases in which the absorbable pins made of poly-p-dioxanone were used for internal fixation at Seoul National University Hospital between December, 1987 and September, 1989, and report on 11 patients who had at least 6 months follow-up(average 9.1 months). The results were graded as excellent(5 cases), good(4 cases), poor(0 case), and questionable(2 cases). In the 9 cases where the absorbable pins were used for internal fixation of the intraarticular fractures or defects, satisfactory(excellent or good) results were obtained. In the 2 cases where the absorbable pins were used for intramedullary nailing, the role of the pins was questionable. There were no complications such as wound sinus formation, secondary displacement of the fragemts and delayed union or nonunion.

This study was planned by the necessities of basic information about the effects of Korean Ginseng upon fracture healing and biomechanical properties of bone. Three hundred white mice were used for this study, and we could have tested the biomechanical properties in one hundred and nintyfour. The bones of the white mice were evaluated by testing gross stability, radiological appearance, and biomechanical properties. It appears that Korean Ginseng has an excellent effect upon early phase of fracture healing of the bone. The summary of this study are as follows: 1. With near maximal dose, Korean Ginseng showed very excellent effect upon early phase of the fracture healing. 2. There was no apparent effect on remodeling phase of the fracture healing with Korean Ginseng of near maximal dose. 3. Korean Ginseng appeared to have no effect on fracture healing with minimal dose. 4. Upon biomechanical properties of the bone, Korean Ginseng was seemed to be effective with near maximal dose. But, there was no definite evidence for that.

Peripheral nerve injury occurs mostly in company with tendon and muscle injuries, fractures, or dislocations. Because of the disabilities and socioeconomic loss caused by such injuries, much attention must be paid to the initial treatment, and later to the reconstruction and rehabilitation. At department of Orthopedic Surgery, Seoul National University Hospital, 336 patients of nerve lesion were treated from Jan, 1980 to Dec, 1988. Among them 128 patients were nerve compression syndrome (carpal tunnel 52 patients, cubital tunnel 40 patients, thoracic outlet 16 patients, others 20 patients), and 50 patients were brachial plexus injury, and 168 cases were peripheral nerve injury. 50 patients of the peripheral nerve injury were treated with reconstruction and 118 patients were treatred with neurorrhaphy, nerve graft, and neurolysis. Of the 118 patients, 94 patients were followed up for more than one year, and the results of neurorrhaphy, nerve graft and neurolysis were analyzed. In 46 patients (73.0%) of the patients treated with neurorrhaphy, 7 patients (58.3%) with nerve graft, and 15 patients (78.9%) with neurolysis, good or excellent results were obtained.
