The distal tibial physeal plate is the second most frequently injured physis and the percentile incidence of its injury is reported to reach 11 percent of all physeal injuries. After physeal injuries, many complications may follow such as angulatory deformity, incongruity of the joint surface, and growth disturbance, which are well recognized. Therefore, for preventing these complications, we have to know mechanism of injury and position of foot in injury. There are several published articles about classification of these injuries. The first traumatological classification of ankle injuries in children is the one proposed by Bishop. Although there were many reports about classification since Bishop, those did not mention the position of foot in injury. Recently a modified classification by Dias and Tachdjian added the postiton of the foot during injury to the direction of the force as Lauge-Hansen did. There were only few reports about epiphyseal and physeal injuries of the ankle in Korea. Also, we could not find the reports which dealt with more than forty cases. The authors have made a clinical analysis on forty cases of childrens ankle fractures, and among them twenty-two could be followed over a year, who were treated at the Department of Orthopaedic Surgery, Kang-Nam St. Marys Hospital, from June 1981 to December 1986. Children were in age of 3 to 16 years. Forty cases were classified according to modified Dias and Tachdjians. 15 out of 40 cases (37.5%) had supination and external rotation injury, which is the most frequent mechanism of injury in this series. However, one case (2.5%) which was suspected to be axial compression type could not be accommodated to this classification. Twenty-seven cases were treated by gentle closed reduction and immobillization in a plaster cast, and thirteen by open reduction and internal fixation. Among the 22 cases who were followed over a year, five cases had complications, such as angulatory deformity, incongruity of the joint surface, and growth disturbance. Three cases out of these five cases had incongruity of the joint surface.

Low back pain is probable the second most common disease entity to upper respiratory infection in developedconuntry. We were missing at least 50% of the pathologic conditions by using conventional diagnostic modalities inlow back pain. They did tell us nothing or little about facet abnormalities, lateral recesses, vertebral canal andsoft tissues surrounding lumbar spines. High resolutional CT has been the biggest turning point in the diagnosisand management of low back pain. CT make a contribution to reducing the morbidity and probable the cost ofevaluating patiens with low baack pain, and to increasing diagnostic accuracy. We observed 100 cases of lumbar CTusing TCT 80A scanner for the evaluation of low back pain during the period from Apr. 1985 to Sept. 1985 atChung-Ang University Hospital. Lumbar CT scan reveals high-positive findings(98%) in low back pain patients.Common low back disorders in CT are disc bulging(53%), herniated nucleus pulposus(32%), degenerative arthritis inposterior facet joints (27%), spinal stensosis(20%) and postoperative spines(15%). Uncommon low back disorders inCT are compression fracture of verebral bodies, spondylolysis or spondylolisthesis, tropism, transitionalvertebra, Scheuerman's disease, limbic fracture, transverse process or articular process fracture, sacroiliacjoint subluxation, conjoined nerve root and meningocele.

188Re (beta=22 MeV; gamma=155 keV; T1/2=16.9 hours) is an attractive therapeutic radioisotope which is produced from decay of reactor-produced tungsten-188 parent (T1/2=69 days). 188W has been produced from the double neutron capture reaction of 186W. 188Re can be easily obtained by elution of saline on alumina based 186W/188Re generator, which is commercially available. Complexes labelled with 188Re have been developed for the radiotherapy treatment of diseases because of the desirable nuclear properties of the radioisotope and it's chemical properties similar to those of technetium, a well established diagnostic agent.

Purpose: Dislocation is the second most common cause of failure, after implant loosening, in revisional THA (Total hip arthroplasty), and its evaluation and treatment still remain controversial issue. This study was undertaken to evaluate the risk factors after THA using the posterolateral approach and posterior soft tissue repair. Materials and Methods: Between January 1998 and May 2003, 211 consecutive primary total hip replacement arthroplasties using the posterolateral approach and posterior soft tissue repair were performed by the same surgeon. To compare the dislocation groups (6 cases) with the non-dislocation groups (205 cases), we randomized 120 of the non-dislocation cases. The risk factors for hip dislocation were categorized into patient factors and surgical factors. Patient factors included gender, age, preoperative diagnosis, underlying systemic disease, and alcoholic history. Surgical factors included position of the component (acetabular version and inclination, femoral anteversion), leg length discrepancy, and sum of anteversions of the cup and stem. Their parameters were measured on postoperative radiographs. Statistics were performed with Fishe`s Exact test and T test. Results: Dislocations occurred at an overall incidence rate of 2.8% (6/211cases). There were 4 (1.9%) cases of anterior dislocations and 2 (0.9%) cases of posterior dislocations. Dislocations occurred on average at postoperative day 6.1 and all dislocated hips were reduced with the closed method, except for one case that was treated surgically. There was no statistical significance in patient factors between the two groups, except for neurologic disease and alcoholic history. However, the sum of the acetabular and femoral anteversions in the anterior dislocation group was larger than that of the non-dislocation group by approximately 19 degrees. Conclusion: Our results demonstrated that by using the posterior approach and repair of soft tissue, the posterior dislocation rate after total hip replacement arthroplasty can be reduced and the sum of the acetabular and femoral anteversions had more influence on dislocations after THAs than did either anteversion alone.

PURPOSE: We evaluated both the patients and the normal volunteers to determine the diagnostic criteria of subacromial impingement syndrome. MATERIALS AND METHODS: We analyzed the radiologic finding of Thirty degree of caudal tilt view (TCTV) and Supraspinatus outlet view (SOV) of 100 shoulders from 85 patients with clinically proved subacromial impingement syndrome and normal 100 shoulders from 60 volunteers. RESULT: In TCTV, the protrusion of acromion below the line of extension from inferior surface of clavicle was shown in 94% of the patient group and 48% in normal group. Sharp tip of acromial protrusion was detectable in 55.3% of the patient group and 10.4% in normal group. In SOV, curved type of acromion was seen in 53% of the normal and 50% in patient group. Hooked type of acromion was detected in 3% and 31% of the normal and patient group, respectively. CONCLUSION: Protrusion of acromion at TCTV itself was not a criteria of subacromial impingement syndrome, but more than 7 mm below the line of extension from inferior surface of clavicle was meanigful. In SOV, hooked type of acromion was a criteria of subacromial impingement syndrome but curved type is was not a finding of diagnostic significence. Acromial spur formation on TCTV and SOV was important criteria of subacromial impingement syndrome.

We have experienced a 14 year old female patient who had suffered from headache, dizziness, exertional dyspnea and chest pain during 6 months. She was diagnosed as primary pulmonary hypertension by ultrasonogram and cardiac cathererization. On the cardiac catheterization, there was elevated pulmonary artery pressure and normal pulmonary wedge pressure. We report this case with related literature review.

BACKGROUND: The majority of Staphylococcus aureus strains isolated from atopic eczema skin produce toxins like enterotoxin B or toxic shock syndrome toxin-1(TSST-1) as a superantigen and these toxins may contribute to the exacerbation of this skin disease. OBJECTIVE: We designed this study in order to investigate the effect of toxic shock syndrome toxin-1 on IL-4, interleukin-10(IL-10), interleukin-12(IL-12) and IFN- r production by peripheral blood mononuclear cells from normal and atopic patients. METHODS: Peripheral mononuclear cells obtained from ten patients with severe atopic dermatitis and ten healthy volunteers were stimulated with TSST-1 and cultured for 4 days. The amount of IL-4, IL-10, IL-12 and IFN- r in the culture supernatants were determined by a solid-phase enzyme- linked immunosorbant assay. RESULTS: l. After stimulation with TSST-1, IL-4, IL-10, IL-12 and INF- r, production of peripheral mononuclear cells from both atopic patients and healthy volunteers were increased. 2. After stimulation with TSST-1, the amount of IFN- r in the culture supernatants was significantly greater in the healthy controls than in the atopic patients. 3. After stimulation with TSST-1, the amount of IL-10 in the culture supernatants was significantly greater in the healthy controls than in the atopic patients. CONCLUSION: This data indicates that TSST-1 induces Thl-type and Th2-type cytokines associated with parallel Thl and Th2 stimulation in atopic patients and healthy donors. In addition, peripheral mononuclear cells from atopic patients have a diminished capacity to synthesize IFN- r and IL-10 in vitro in response to stimulation with TSST-1. Our results suggest that TSST-1 is not considered as a really important aggravating factor in atopic dermatitis.
