Sixteen microvasular free flap transfers have performed during recent two years in this department, which was first attempt in Korea. Neurovascular free flap was nine and vascular free flap was seven. The donor flaps were thirteen dorsalis pedls falps, two groin flaps and one latissimus dorsi flap respectively. The recipient sites were heel pad loss, vital organ exposure and scar contracture lesions in extremity. Their main cause of soft tissue defect was traumatic in all. All patients have experienced more than two times of split thickness skin graft before free flap transfer. The success rate of vascular free flap transfer was 94%. The only one failure case was due to venous thrombosis, but secondary split thickness skin graft performed with satisfactory result. The follow up period was from 5 months to 20 months. Sweating in transferred free flap was found at all neurovascular free flap within postoperative 4 months. Adequate 2-point discrimination was obtained at six patients of nine neurovascular free flaps and protective sensation seems to progressively improve in remained three patients. Two point discrimination was shortened at hand after neurovascular dorsalis pedis flap transfer in two cases. The weight bearing function at heel pad region and tactile sensation at hand have satisfactorily recovered after free flap transfer. Free flap transfer have many advantages compare to conventional skin graft, such as shorter therapeutic time, lesser physical and economic burdens, primary covering to vital organs and protective sensation of neurovascular free flap transfer. The most important factors are meticulous microvascular operation technique and anatomic knowledge.

It is notoriously difficult to obtain a sound bony union of congenital paeudarthrosis of tbe tibia with conventional methods. This paper is the results of using the free vascularized fibular graft for congenital pseudarthorsis of the tibia in 7 patients since 1978 in this hospital, which is the first attempt in Korea. During the follow-up periods from 9 months to 32 months, 5/7 patients(71%) had good or excellent bony union, 2 patients had bone resorption at tbe distal site of grafted bone and required a second supplementary cancellous bone graft with electrode insertion. So it is thought that the free vascularized fibular graft is one of good methods of treatment for congenital pseudarthrosis of the tibia.

Vesicoureteral reflux (VUR) is common disease found in up to 70% of children who have urinary tract infection, and the various type of antireflux surgerys were used to correct the problem. Among them, Gil-Vernet antireflux technique is a useful method and it has many advantages such as procedure of simplicity, shorter operative time, and lower complication rate along with maintaining high success rate. We present six cases of vesicoureteral reflux who had been managed with Gil-Vernet antireflux technique, and review the advantages, disadvantages, complications, and usefulness of the procedure.

Birth brachial plexus palsy (BBPP) is usually caused by plexus traction during difficult delivery. Although the possibility of complete recovery is relatively high, 5% to 25% of BBPP cases result in prolonged and persistent disability. In particular, muscle imbalance and co-contraction around the shoulder and elbow cause abnormal motor performance, osseous deformities, and joint contracture. Physical and occupational therapies have most commonly been used, but these conventional therapeutic strategies have often been inadequate, in managing the residual muscle imbalance and muscle co-contraction. Therefore, we attempted to improve the functional movements, by using botulinum toxin type A, to reduce the abnormal co-contraction of the antagonist muscles.

BACKGROUND: Fracture-dislocation of the proximal interphalangeal (PIP) joint is a relatively common injury. Various treatments for fracture-dislocation of the PIP joint have been reported. In the present study, we performed open reduction through a midlateral incision using absorbable sutures to reduce the small bone fragments and performed volar plate repair. METHODS: We treated nine patients with fracture-dislocation of the PIP joint with small fractured bone fragments too small for pinning or screw fixation. Patients with volar plate injury were treated with open reduction and volar plate repair at the periosteum of the middle phalangeal bone base by the modified Kessler method using absorbable sutures. All patients were placed in a dorsal aluminum extension block splint, which maintained the PIP joint in approximately 30 degrees of flexion to avoid excessive tension on the sutured volar plate. RESULTS: At a mean final follow-up of postoperative 9 months, all patients were evaluated radiographically and had adequate alignment of the PIP joint and reduction of the displaced bone fragments. Range of motion was improved and there were no complications. CONCLUSIONS: This technique is an excellent alternative to the current method of treating patients with fracture-dislocations that include small fragments that are too small for pinning or screw fixation. It is a less invasive surgical method and enables stable reduction and early exercise without noticeable complications.

Hemangiopericytoma is uncommon vascular neoplasm that arises from pericytes arround the capillary walls. It was first described as a distinct vascular neoplasm by Stout and Murray in 1942 The anatomic distribution is widespread throughout the body, with approximately one third occur in the head and neck. No sex predilection has been found. Although middle age appears to be the most prevalent time of onset, this neoplasm has been found in all age groups. The differentiation between benign and malignant hemangiopericytoma can be difficult. Although the majority of these tumors are benign, there are malignant variants that can metastasize. Metastasis of seemingly benign tumors may appear year of decade later, so long term close follow-up is needed The treatment of choice is complete surgical excision of the tumor. Despite their vascular origin, these tumors are relatively radioresistant. Radiation therapy is reserved for inoperable metastases or treatment of postoperative surgical fields. Here we present a case of hemangiopericytoma occuring on the Lt. buccal mucosa.

BACKGROUND: Medical decisions concerning the prolongation of life, the right to die and euthanasia are among the most extensively discussed issues within medicine and law today. The purpose of this study was to evaluate the attitudes of medical students and housestaff toward euthanasia. METHODS: From July 15 to September 15 of the 1998, the responses of 180 medical students and 132 housestaff to a self-administered questionnaire were analyzed to identify attitudes toward euthanasia. Over 312 respondents about attitudes toward euthanasia, the analysis of differences between proportions was made by the Chi-square test. RESULTS: About 69.9% of the respondents thought euthanasia should be legalized. The findings suggest that Buddhists (77.5%) and non-religious groups (88.1%) tend to support euthanasia more than Christians. Futhermore, medical students (74.4%) support euthanasia more than housestaffs(63.6%), male(75.1%) more often than female(57.9%). About 73.1% of the respondents said that active euthanasia is not justifiable, and 79.2% said that they do not like performing active euthanasia. In respect to passive euthanasia, 69.0% said that it is not ethically justifiable, but 63.0% would perform this as if it were legal. Housestaffs of internal medicine (76.9%) were more willing to do euthanasia than pediatrics (70.0%), surgery (63.6%), family practice (53.8%) and Ob/Gyn (33.3%). CONCLUSION: Respondents have positive attitudes toward legalization of euthanasia.. Most considered that passive euthanasia is not morally justifiable. But if it were legalized, they would be willing to do euthanasia, while they would still be disturbed by active euthanasia. The opinions of physician and medical students directly affect patient care and their attitudes must be considered if clear policies are to be developed concerning euthanasia.

Hypoglossal nerve injury is an uncommon complication following endotracheal intubation. A transoral procedure including endotracheal intubation may result in hypoglossal nerve compression at the lateral margin on the hyoid bone and inner mandibular margin at the tongue base. A 50-year-old patient undergoing rotator cuff repair developed a transient unilateral postoperative hypoglossal nerve injury following uncomplicated endotracheal intubation for general anesthesia. The following day the patient complained of difficulty with tongue movement and buccal manipulation of food, and had slurred speech. An electrophysiologic assessment confirmed a diagnosis of unilateral hypoglossal nerve palsy. The symptoms resolved spontaneously and completely by 6 weeks. The possible etiology of the injury is discussed, and related literatures are reviewed.

OBJECTIVE: To quantify activities of bulbocavernosus reflex (BCR) using root mean square (RMS) value of motor unit action potentials in power spectrum analysis. METHOD: Twenty-six male patients with spinal cord injury were studied. The BCRs were evaluated by one examiner. The patients were assigned into absent, hypoactive and normal reflex groups according to the degree of BCR activity. The electrophysiological activities of the BCRs were evaluated by the RMS value of the motor unit action potentials in power spectrum analysis recorded from the bulbocavernosus muscle using concentric needle electrode. RESULTS: The BCR by clinical examination was absent in 6 patients, hypoactive in 10 patients and normal in 10 patients. RMS values of absent, hypoactive and normal BCR groups were 15.1+/-3.6 uV, 26.7+/-13.2 uV and 36.3+/-4.8 uV, respectively. RMS values of three groups were significant different (p=0.028) and showed significant correlation (r=0.714, p= 0.005). CONCLUSION: There was strong correlation between RMS value of motor unit action potentials of bulbocavernosus muscle and degree of BCR activities estimated by clinical examination in patients with spinal cord injury.
