Injuries to the acromioclavicular joint are usually the result of force applied downward to the acromoion. Surgery treatment modalities for grade IU complete acromioclavicular dislocation are extremely varied and usually successful. 13 cases of complete acromioclavicular dislocation were operated by techniuqe of Kirschner wire with tension-band wiring at Wonju Christian Hospital from June 1984 to Oct. 1985. And they had been followed for average 17.8 months and following results were obtained. l. Of the 13 cases, male was 8 cases(61%) and female was 5 cases(39%) . 2. The most common cause of injury was traffic accident. Nexts were fall down, slip down and direct blow. 3. Results were evaluated by using Weaver and Dunn criteria, 12 cases(92.3%) were good and 1 case was fair but this technique involved a more extensive implant removal that required general anesthesia. Therefore, AO tension-band wiring is thought useful operative method in the treatment of acromioclavicular dislocation.

Galeazzis frature has been described as a fracture of the radius complicated by a dislocation of the distal radioulnar joint. This fracture, with angulation of the distal radius and dislocation of the distal radioulnar joint, shows the tendency to redisplacement after reduction due to a variety of factors including the brachioradialis muscle, the pronator quadratus muscle and the thumb abductors and extensors. Because of these factors, this fracture may rarely be treated by manipulation and plaster immobilization alone. The treatment of choice for Galeazzis fracture is open reduction and internal fixation. The author reviewed the cases of 28 patients with Galeazzis fracture who had been treated at the Department of Orthopedic Surgery, Yonsei University Wonju College of Medicie from January 1978 to December 1986. This study emphasized the nature of the injury, the level of the radial fracture, treatment and results. The results were as follows ; 1. The subjects included 2 children and 26 adults. Males were affected more frequently than females, and the sex ratio was 6: 1 2. The causes of injury included car accidents in ten cases(36%), falls in eight cases(29%), injuries from machinery in five cases(18%), direct blows in four cases(14%) and explosion in one case(3%). 3. The fracture occured most often at the junction of the middle and distal thirds of the radial shaft in thirteen cases(47%), and less often in the middle third of the radial shat, eitht cases(29%). Infrequent sites of fracture included the junction of the proximal and middle thirds in four cases(14%), the distal third in two cases(7%) and the proximal third of the radius in one case(3%). 4. Twenty-two cases(78%) experienced fracture composed of only two fragmented, but six cases(22%) were multifragment fractures. The frature was oblique and in one case, spiral. In twenty-two cases, the fractures were closed and in six cases, open. Three cases of open fractures had grade III soft tissue injuries. 5. Roentgenograpghic diagnosis of the distal radioulnar joint disruption was possible in 82% of the cases. 6. Associated injuries were noted in 57% of the cases including six cases of head injuries, four cases of head injuries, two cases of injury to the lower extremities, two cases of spinal injury, one cases of a fractured humerus. 7. Conservative treatment was given in five cases and operative treatment twenty-two cases. Conservative treatment gave excellent results in one case, fair results in two cases, while operative treatment resulted in an excellent outcome in thirteen cases, a fair outcome in eight cases and poor in one case. 8. Six cases experienced complications including delayed union in two cases, subluxation of the distal radioulnar joint in two cases, ahgulation in one case and infection in one case.

PURPOSE: The incidence of lung cancer in patients with idiopathic pulmonary fibrosis(IPF) is higher than that of general population. To evaluate the frequency and CT findings of lung cancer associated with idiopathic pulmonary fibrosis, we analyzed 19 patients with lung cancer associated with idiopathic pulmonary fibrosis. MATERIALS AND METHODS: We analyzed retrospectively 19 patients with histologically confirmed lung cancer out of 208 patients diagnosed as IPF either by CT and clinical findings(n=188) or histologically(n=20). All 19 patients were male, aged 40--85 years (mean 66 years). Scanning techniques were conventional CT in 12 patients, HRCT in 1 patient and both conventional CT and HRCT in 6 patients. We analyzed the CT patterns of lung cancer and IPF, locations of the tumor and histologic types of lung cancer. RESULTS: The incidence of lung cancer in patients with idiopathic pulmonary fibrosis was 9.1%(19/208). In 11 of 19 patients, CT findings of lung cancer were ill-defined consolidation-like mass. Lung cancer was located mainly in lower lobes(right lower Iobe;10/19, left lower Iobe;5/19) and at the periphery(12/19). Histologically, squamous cell carcinoma was the most common cell type (11/19). CONCLUSION: The incidence of lung cancer in patients with idiopathic pulmonary fibrosis was much higher than that of general population. Typical CT findings of lung cancer were predominantly ill-defined consolidation like mass at the peripheral lung portion which is the [ocatiaon where the most advanced fibrosis occur.

PURPOSE: To analyse the risk factors for recurrence of hemangiomas in extremities after surgical treatment and to compare with those of trunk. MATERIALS AND METHODS: 120 cases of hemangioma with surgical treatments from June 1998 to September 2009 were analysed. 53 cases with surgical treatment on trunk in the same period were set to be the control group. We analyze several factors: age, location, site, size, histologic types and correlation between recurrence and each risk factor using logistic regression analysis. RESULTS: Recurrence rate was 11.7% in extremities and 9.4% in trunk. There were no correlation between recurrence and age, site, size, histologic type. But, there was stastically significant correlation between recurrence rate and location, especially hand, forearm, feet in extremities and head and neck in trunk. CONCLUSION: Recurrence after surgical treatment of hemangioma is highly prevalent in anatomical location such as, hand, foot and forearm those are difficult to achieve complete resection because of close to neurovascular structures. Careful observation should be needed owing to incomplete resection can occurs recurrence.

The authors attempted to examine the allelic association between the A1 allele of Dopamine D2 receptor and schizophrenia, alcoholism, drug addiction in Koreans. Schizophrenic patients(n=31), alcoholism(n=65), drug addiction(n=18) and controls(n=52) were examined by case-control study for distribution of the Taql polymorphism of the dopamine D2 receptor gene in Korean population to minimize the effect of racial differencies in gene frequencies. In schizophrenics, the numbers of schizophrenics with A1A1, A1A2, A2A2 were 9(29%), 15(48%) and 7(22%) respectively and in alcoholics with A1A1, A1A2, A2A2 were 14(21.5%), 36(55.4%) and 15(23.1%) respectively and in drug addiction with A1A1, A1A2, A2A2 were 4(7.6%), 24(46.2%) and 24(46.2%) respectively. The prevalence of the A1 allele in schizophrenics, alcoholics, drug addiction and controls were 77%, 76.9%, 67% and 53.8% respectively. And the frequency of the A1 allele in schizophrenics, alcoholics, drug addiction, and controls were 0.53 0.49, 0.39 and 0.31 respectively. There was significant difference in the frequency of the A1 allele between schizophrenics, alcoholics and controls. We also classified our alcoholic population. For classification by severity, we used the median MAST score 30 in our samples. There was also significant difference in the frequency of the A1 allele between less severe group(0.42) and more severe group(0.57). This data suggest that the A1 allele is associated with schizophrenia and alcoholism in Korean. Furthermore the prevalence of the A1 allele increased in more severely affected alcoholics. The authors conclude that our data support an allelic association between the A1 allele at dopamine D2 receptor and schizophrenia, alcoholism. These results suggest the A1 allele of the DRD2 gene is associated with a number of behavior disorders in which it may act as a modifying gene rather than as the primary etiological agent.

PURPOSE: To determine the accuracy of automated computer aided volumetry for simulated small pulmonary nodules at computed tomography using various types of phantoms MATERIALS AND METHODS: Three sets of synthetic nodules (small, calcified and those adjacent to vessels) were studied. The volume of the nodules in each set was already known, and using multi-slice CT, volumetric data for each nodule was acquired from the three-dimensional reconstructed image. The volume was calculated by applying three different threshold values using Rapidia(R) software (3D-Med, Seoul, Korea). RESULTS: Relative errors in the measured volume of synthetic pulmonary nodules were 17.3, 2.9, and 11.5% at -200, -400, and -600 HU, respectively, and there was good correlation between true volume and measured volume at -400 HU (r=0.96, p<0.001). For calcified nodules, relative errors in measured volume were 10.9, 5.3, and 16.5% at -200, -400, and -600 HU, respectively, and there was good correlation between true volume and measured volume at -400 HU (r=1.03, p<0.001). In cases involving synthetic nodules adjacent to vessels, relative errors were 4.6, 16.3, and 31.2 % at -200, -400, and -600 HU, respectively. There was good correlation between true volume and measured volume at -200 HU (r=1.1, p<0.001). CONCLUSION: Using computer-aided volumetry, the measured volumes of synthetic nodules correlated closely with their true volume. Measured volumes were the same at each threshold level, regardless of window setting.

The objective of this paper is to introduce the schematic protocol of radiofrequency (RF) ablation for the treatment of varicose veins. Indication: anatomic or pathophysiologic indication includes venous diameter within 2-20 mm, reflux time > or =0.5 seconds and distance from the skin > or =5 mm or subfascial location. Access: it is recommended to access at or above the knee joint for great saphenous vein and above the mid-calf for small saphenous vein. Catheter placement: the catheter tip should be placed 2.0 cm inferior to the saphenofemoral or saphenopopliteal junction. Endovenous heat-induced thrombosis > or =class III should be treated with low-molecular weight heparin. Tumescent solution: the composition of solution can be variable (e.g., 2% lidocaine 20 mL+500 mL normal saline+bicarbonate 2.5 mL with/without epinephrine). Infiltration can be done from each direction. Ablation: two cycles' ablation for the first proximal segment of saphenous vein and the segment with the incompetent perforators is recommended. The other segments should be ablated one time. During RF energy delivery, it is recommended to apply external compression. Concomitant procedure: It is recommended to do simultaneously ambulatory phlebectomy. For sclerotherapy, it is recommended to defer at least 2 weeks. Post-procedural management: post-procedural ambulation is encouraged to reduce the thrombotic complications. Compression stocking should be applied for at least 7 days. Minor daily activity is not limited, but strenuous activities should be avoided for 2 weeks. It is suggested to take showers after 24 hours and tub baths, swimming, or soaking in water after 2 weeks.

Neurofibromas are common benign tumors and can originate from any nerve tissue in the body. A solitary neurofibroma in breast parenchyma has rarely been reported, however. We report a neurofibroma originating from breast parenchyma in a 61-year old woman. On mammography, the mass appeared as a well marginated and circumscribed mass, suggesting a benign tumor, and after excisional biopsy, was pathologically proven to be a neurofibroma.

Abrupt increase in the size of cervico-mediastinal tumor due to infection or spontaneous hemorrhage into cyst can induce severe tracheal compression and therefore sudden death. A 5 year old boy, who had a history of URI, had an enlarging cystic hygroma on the right side of the neck and anterior mediastinum. Under diagnosis of the cervico-mediastinal cystic hygroma, surgical removal was scheduled. After induction of anesthesia, intubation was done without any difficulty. A few minutes later, signs of partial airway obstruction were appeared. And within a very short period, total airway occlusion occurred. The tracheal tube was removed and manual ventilation was performed with positive airway pressure, but ineffective. We attempted to puncture cricothyroid membrane with 14 Gauge needle in order to ventilate manually. As soon as we puncture cricothyroid membrane, straw-colored fluid, not air, gushed out through a needle. After aspiration of about 200ml of cystic fluid, the obstructive signs disappeared and the patency of the airway was maintained. Intraoperatively, no more airway problems occured and vital signs were stable. And postoperatively, patient had no specific complications and discharged on the 7th day after operation.
