The most common adverse effect of intravenous heparin is hemorrhage. Of the these, retroperitoneal hemorrhage and femoral neuropathy secondary to heparin anticoagulation has reported in 1966 for the first time by DeBolt and Jordan. We experienced a case of spontaneous retroperitoneal hemorrhage due to iliopsoas muscle hematoma in patient with myocardial infarction receiving intravenous heparin for a 3 days in therapeutic doses. The pathophysiology of iliopsoas muscle hematoma has not yet been cleared. But because of the possibility of large amount in volume, retroperitoneal hemorrhage has been known as a serious adverse effect that leads to the hypovolemic shock and death. In this article, we described the clinical manifestation, the importance of the early diagnosis and diagnostic clues and associated factors of the retroperitoneal hemorrhage in patient receiving intravenous heparin.

Arteriovenous fistula could occur rarely followed by lumbar disk operation. There are very few case reports in the literature. We have experienced a case of arteriovenous fistula, which has been corrected surgically.

Colloidal gold 198Au were injected into 40 knee joints of rabbits for the study of the change of synovial membrane. We verified even distribution of Colloidal gold 198Au about knee joints by use of scintigraphy. After then, histopathological examinations were performed by periodic intervals. The following results are obtained form this study. l. Intra-articular injection of Colloidal gold 198Au into rabbit's knee joints resulted in a mild resctive inflammation at synovium. In was charscterized by an infiltration of eosinophils and by sclerotic changes in the subsynovium and by fibrosis of synovial vessels. 2. From this study, intra-articular injection of Colloidal gold 198Au may by benefit to treat the chronic synovial effusion in human.

In fusion of lumbar spine, every fused motion segments shows varisble limitation of motion in flexion, extension and lateral bending according to their types and level of fusion. The motion segment of lumbar spine is three joint complex which consists of posterior two articular facet joints and an anterior intervertebral disc. Nowadays, orthopedic surgeon prefer anterior fusion due to direct identification and removal of diseased tissue, reduction of fractured fragments, restoration of intrevertebral space, early rehabilitation and no damage of nerve root and cord, and is prefered short Segmental Spinal Instrumentation(e.g. Cotrel Dubousset Instrumentation, etc.) due to short and rigid fusion, no necessity of external support and low limitation of motion. We studied 58 cases of fused lumbar spine which had been operated since Sep.1983, by X-ray overlay method and 20 cases of healthy lumbar spine as eontrol group. In this study, we obtained following results ; 1. Harrington Rod Instrumentation reveals the most remarkable limitation of motion, whereas, C.D.I. and A.I.F. reveal the least limitation of motion. 2. Distinct differencies of motion are repersented by its range of fusion and range of motion in 2 segmental fusion reveals remarkable decreasement from range of motion in single segmental fusion. 3. In single segmental fusion, the most limitation of motion was represented in Harrington Rod Instrumentation and posterior fusion with bone graft. There is remarkable decreasement of flexion at lumbosacral junction by its site of fusion. 4.In double segmental fusion, the most limitation of motion was represented in Harrington Rod Instrumentation and there is no significant difference of motion by its site of fusion.

This case report describes the treatment of a 23-year, 8-month-old female patient with a Class II malocclusion who showed severe bidentoalveolar protrusion and anterior crowding. The treatment plan consisted of extracting all the first premolars, decrowding and en masse retraction of the upper six anterior teeth and lower anteriors. The upper C-plate placed in the midpalatal area combined with lingual sheath fixtures were used as substitutes for posterior anchorage teeth during upper anterior retraction. Preadjusted brackets (0.022-inch) were used for upper anterior decrowding. A 0.9 mm diameter stainless steel lever-arm soldered to the main arch wire facilitated controlled retraction of upper anteriors. The upper and lower dentition was detailed using a tooth positioner during the finishing stage. Correct overbite and overjet were obtained by decrowding and retraction of the upper six anterior teeth into their proper positions. Use of the C-plate and lingual appliances provided ideal anchorage to enhance the improvement in facial balance. The active treatment period was 19 months. The treatment result was stable 13 months after debonding.

Purpose: To obtain an overview of the surgical practices for the management of intermittent exotropia among experienced surgeons. Methods: We conducted a survey of members of the Korean Association for Pediatric Ophthalmology and Strabismus, who had experience of > 15 years in strabismus surgery, via e-mail. Surgical methods for basic-type intermittent exotropia, angle of deviation for determining the surgical dose, reasons for surgical dose adjustment, and the postoperative target angle of deviation were analyzed. Results: Bilateral lateral rectus recession was preferred over unilateral recession and resection for basic-type intermittent exotropia with or without a dominant eye. The preoperative maximum angle of deviation was preferred for determining the surgical dose by 56% of the participants. Two-thirds of the participants preferred to reduce the surgical dose in specific circumstances, lateral incomitancy being the most common reason. In case of true divergence excess-type intermittent exotropia, 47.7% of the participants reduced the surgical dose. The most preferred target angle of deviation at 1 day postoperatively was 11-15 prism diopter esodeviation, as reported by 40% of the participants. Conclusions Although experienced surgeons had different surgical preferences for intermittent exotropia, a general trend was found. This survey may be a useful reference for beginners in strabismus surgery.

PURPOSE: The aims of the present study were to quantitatively assess graft height changes after sinus lift procedures and to analyze the factors that influenced graft height changes, including the residual bone height before surgery, surgical approach, and tooth type. METHODS: A total of 39 maxillary posterior implants placed during a simultaneous sinus lift procedure were evaluated. Panoramic radiographs of all patients were taken immediately after implant installation and at 3 months, 6 months, 1 year, 2 years, and 3 years. To analyze graft height changes over time, we measured the distance between the implant platform and the base of the grafted sinus floor at 3 locations. The radiographs were analyzed by a single examiner. RESULTS: Graft height tended to decrease over time, and a statistically significant difference was observed at 2 years compared to baseline (P < 0.05). There was no statistically significant difference in graft height change according to the surgical approach or tooth type. For residual bone height, a statistically significant difference in graft height change was found between those with 4–7 mm of residual bone height and those with ≥7 mm (P < 0.05). CONCLUSIONS: Graft height after sinus lift procedures significantly decreased at 2 years compared to baseline after sinus augmentation. Further studies should be done with controlled variables, and prospective studies with 3-dimensional images are needed to clarify the factors that influence graft height changes.
