We meet much difficult problem to solve in the treatment of the forearm fractures which are not encountered in the treatment of fractures of the other long bone and there are many reports on the results of treatment of forearm fractures and many methods have been introduced. In the late 1950's ASIF compression plate was invented and developed by Muller, Allgower, and Willenegger and it has shown excellent union rate and functional results in the treatment of forearm fractures. From Jan. 1971 to Dec. 1979, we have experienced 71 cases of fresh or old forearm fractures treated by different methods and devices and among them, 53 patients, those were treated with compression plate and other various internal fixation devices, were possible to trace for more than 3 months. The Author divided the traceable patients into two groups, the one was the group treated with compression plate and the othtr one was the group treated with other various internal fixations, and compared the results in the aspect of healing time and functional results. The results were as follows; 1. Among 71 patients, 45 patients (36.6%) were fresh and 26 were old cases. Of 61 adult patients 21 cases (34.4%) exhibited severe soft tissue injury due to crushing machinary injury. 2. There was 24 (33.8%) cases of open fractures and the most common fracture site was middle one-third of both radius and ulna. 3. The period between operation and exercise was 7.3 weeks in fresh cases which were treated with compression-plate fixation and 10.3 weeks in old cases with other fixation devices. 4. The time of radlological union was comparatively rapid in compression-plate fixation group, acute cases and radial fractures when compared it with those treated with other fixation devices, old cases and ulnar fractures, respectively. Radiological union time in average was as follows; Radius, compression-plate fixation: 12.1 weeks ulna, compression-plate fixation: 12.4 weeks redius, other fixation devices 14.9 weeks ulna, other fixation devices 15.5 weeks 5. By Anderson's functional criteria, the ratio of excellent or good results was as follows, Acute compression-plate fixation: 87% Acute, other fixation devices 67% Old, Compression-plate flxation: 67% Old, Other fixation devices 23% 6. Achieved bony union in all cases in compression-plate fixation group and experienced 3 cases of non-union in the group treated with other fixation devices. Among 3, two cases of non-union were due to post-operative infection and technical failure and the other one was a solitary ulnar fracture which was treated with rush pin.

Ewing's sarcoma had never been described as a primary tumor outside bone, although other malignant skeletal tumors, such as osteogenic sarcoma & chondrosarcoma, are known to arise from extraskeletal soft tissues. In 1975, Angervall & F.M. Enzinger reported 39 cases of small, round or oval cell sarcomas occuring in the soft tissues and considered histologically indistinguishable from Ewing's sarcoma of bone. Recently, We experienced one case of extraskeletal neoplasm resembling Ewing's sarcoma of bone which it was located deeply in the calf area of young female patient and the case review has been followed until the death, approxlmately 10.5 months after removal.

A very rare case of multifocal eosinophilic granuloma without extraskeletal involvement in 35 year-old ma was experienced. The patient was admitted for the painful swelling of the right clavicular region and was treati with curettage and autograft of iliac bone. Five months later newly developed the pain in the trochanteric lesion left femur without fever, and also was confirmed as the same lesion. Both lesions were treated with curettage and iliac bone graft, and were followed by radiotheraphy. According to the pathological study, those lesions were confirmed as the multifocal eosinophilic granuloma.

Monitoring of the central venous pressure is a simple, relatively inexpensive method of assessing a patient's cardiac status, circulating blood volume, and vasomotor tone. The simplest way of checking the intrathoraeic location of the catheter tip is by observing oscillation of 2~4cmH2O in the manometer column, synchronous with respiratory cycle. Inaccurate measurements are often obtained by the misplacement of the central venous catheter tip, in addition to the other well-known complications. Radiographic identification of the catheter tip is essential to eliminate these problems. We experienced a case of arrhythmia which appeared upon misplacement of the central venous catheter tip, and confirmed its misplacement by radiographic study.

BACKGROUND: Antibiotics are used prophylactically in surgery to prevent postoperative infection. However, antibiotics administered in large doses can cause a bleeding diathesis as a result of platelet dysfunction. We wondered whether these antibiotics might impair platelet function by interfering with the initial step of platelet activation: the binding of agonists to their specific receptors on the platelet surface. METHODS: In 30 patients (male 18, women 12) undergoing primary elective knee arthroscopic surgery, the whole blood coagulation system was prospectively evaluated before, and 10 and 40 minutes after administration of 1 g of augmentin. All patients who had abnormal preoperative coagulation profiles or who received anticoagulant or antiplatelet, antibiotics therapy within 7 days prior to surgery were precluded. RESULTS: At 10 minutes after augmentin administration 25 of 30 patients had a significant impairment in all phases of whole blood coagulation as monitored by thromboelastography. In contrast, three of 30 patients had a significantly decreased coagulation time. Two of 30 patients had no significant changes of TEG variables. TEG variables were restored toward baseline in fourty minutes after augmentin administration. CONCLUSIONS: Augmentin can cause a significant but transient change in the viscoelastic properties of blood. Coagulation parameters of the TEG should be measured prior to augmentin administration to prevent and prospect a bleeding diathesis as a result of platelet dysfunction.

The authors studied the lung injury induced by endotoxemia and the effects of proteolytic agent on the lung changed by endotoxemia. Sprague-Dawley rats were intraperitoneally administrated with a single dose of endotoxin (4 mg/kg, E. coli 025 : B6 lipopolysaccharide) or with endotoxin and gabexate mesilate (200 mg/kg), a proteolytic agent, concomitantly. Rats of each group were scarificed at 9, 18, and 27 hours after injection. Light and electron microscopic examination were done. The results obtained were summarized as follows: Light microscopic exmination revealed congested capillaries and neutrophilic infiltration in both groups. Electron microscopic findings were interstitial and alveolar neutrophilic infiltration, endothelial swelling with increased pinocytotic vesicles and cytoplasmic process formation, and interstitial edema. Decrease of osmiophilic bodies in the type II pneumocytes had appeared at 9 hours after endotoxin injection. These changes were increased in severity at 18 hours and 27 hours after endotoxin injection. In the group of concomitant treatment of gabexate mesilated and endotoxin, there was no edema at 9 hours after injection. After 18 hours welling of endothelial cell and interstitial edema had appeared. However, the severity of the edema was markedly decreased. Type II pneumocytes showed well preserved osmiophilic bodies. According to these results, it is considered that administration of gabexate mesilate can significantly redeced the lung injury induced by endotoxemia.

In the unusual manifestation of right upper lobe collapse confusing with mediastinal or parenchymal mass, both alteration of the pulmonary vessels and shifting pattern of the collapsed lobe to the periphery on supine positionare the key to the diagnosis of it rather than mediastinal or parenchymal mass. The mechanisms of these unusual manifestation s are obscure, however lobar torsion and gravity factor are considered to be a main process. Authors have experienced 2 cases of unusual manifestations of right upper lobe collapse due to bronchogenic carcinomaduring resent 2 years in Kyung Hee University hospital, and prsent radiologic findings.

One hundred and two patients with fracture of the tibial shaft were treated conservatively at the Department of Orthopaedic Surgery, National Medical Center from 1977 to 1982. In this article, we have analyzed early and late influencing factors upon healing process of the tibial shaft fractures treated with conservative methods. Early factors: Age, fracture type, initial displacement, comminution, open fracture, ipsilateral fibular fracture and associated injuries. Late factors: Interval between accident & final manipulation, distraction of fracture site after skeletal traction, and condition of final apposition. Also, we had the result that the mean healing time of tibial shaft fx. was 17.9 weeks by conservative treatment.

One may sometimes complicated with non-union of the tibia with intact fibula or comparatively early united fibular fracture during the cause of treatment of crural fractures. So that the fibula is to strut the tibial fragment preventing effective contact. Several authors have sporadically reported the removal of a portion of fibula may increase potential compression force across the tibial fracture site and promote bony union of non-delayed union of the tibia. Partial fibulectomy was performed in 9 patients with established nonunion of the tibia at National Medical Center from 1975 to 1982. The results were as follows: 1. Healing occurred in 8 of the 9 cases, and average time to union was 7.4months after fibulectomy. 2. In one case performed B-K amputation due to intractable infection after partial fibulectomy. 3. The average shortening of the involved lower limb was about 1.9cm. 4. All cases did not have significant symptoms at the fibulectomy site after union. 5. Partial fibulectomy proved to be a relatively effective method for the treatment of nonunion of the tibia.

A case of pulmonary alveolar proteinosis is reported. Most of the alveolar spaces were filled with amorphous deep eosinohilic material which revealed strong positive reaction to periodic acid-Schiff staining. Electron microscopic observation of this material showed numerous lamellar bodies in the alveolar spaces and cytoplasms of alveolar macrophages. A part of them were concentric multilamellated type A lamellar bodies and the other were finger printlike type B bodies. Combined type A and type B lamellar bodies were rarely present. From the above features it is suggested that both type A and B lamellar bodies could be transformed one another and those lamellar bodies may be originated from pulmonary surfactant.
