BACKGROUND: Enterococci exhibit intrinsic resistance or high-level minimum inhibitory concentration (MIC) to beta-lactams than other streptococci. This appears to be due to low affinity of penicillin-binding proteins and rarely production of beta-lactamase, which gives the reason of testing beta-lactamase for blood and cerebrospinal fluid isolates. Ampicillin is more effective than penicillin in vitro, and MIC of ampicillin is generally 1 dilution lower than that of penicillin. The purpose of this study is to detect beta-lactamase producing enterococci an6 to compare MICs of ampicillin and penicillin by Vitek system (bioMerieux, Hazelwood, MO, USA) with those by agar dilution method. METHODS: We collected 110 isolates of Enterococcus faecalis and 51 isolates of E. faecium from clinical specimens in 1998. MICs of antibiotics were determined by agar dilution method and Vitek system. We also performed beta-lactamase test by the Cefinase (Becton Dickinson, USA) for 512 isolates of E. faecalis and 189 isolates of E. faecium collected in 1998. RESULTS: The most common sites of isolates were blood, bile, surgical/traumatic wounds, closed and open pus and urine. MICs of ampicillin were 1 to 2 dilution lower than those of penicillin for E. faecalis (P=0.03). But there were no significant differences in MICs for E. faecium (P=0.19). Five isolates (4 E. faecalis and 1 E. faecium) were susceptible to ampicillin but resistant to penicillin. There were no beta-lactamase producing enterococci among 701 isolates tested. CONCLUSIONS: MIC by Vitek system tends to be 1 to 2 dilution lower than MIC by agar dilution method to beta-lactams, and MIC of ampicillin is 1 to 2 dilution lower than MIC of penicillin, which could result in discrepancy in interpretation of susceptibilty tests. A beta-lactamase test for enterococci is not recommeneded for routine test in Korea.

The effect of IDU and cryocautery in the treatment of Herpes Simplex Keratitis was presented. The cryoapplicator was a model of Krwawlcz probe (2 mm in diameter) which was refrigerated in a mixture of dry ice and methyl alcohol. The applicator was appJied on the lesions 7 seconds each and antibiotics and atropine solutions were instilled. A good result was experienced in the treatment of several cases of dendritic kenititis by freezing the corneal lesions by means of cryoappJicator, which had not been responded to IDU therapy speedy. The deep neovascularization of the cornea in a case of stromal keratitis was disappeared after cryocautery for the treatment of the superficial corneal ulcers.

A case of retroperitoneal teratoma was presented in a 40-year-old Korean Male. The radiologic studies were evaluated a space occupying mass containing tooth like a density in the retroperitoneal region. Surgical removal of mass wag performed and histological finding was conformed the benign teratoma.

We performed total hip arthroplasty on a young male adult with paralytic dislocation of the hip due to poliomyelitis. Because of extreme shortening, as well as instability and weakness, the patient was unable to bear weight on the limb. Pastoperative course was complicated by ectopic ossification that compromised the hip and knee motion. Another young male adult with severe spastic cerebral palsy underwent total hip arthroplasty because of an intractable pain due to degenerative arthritis. Initial attempt coupled with adductor tenotomy and obtuator neurectomy ended in gross loosening and acetabular protrusion. Revision consisted of extensive soft tissue release and bone grafting of acetabular defect and use of a protrusion cup and an extra-long stem. Postoperative course was complicated by long-standing serous aseptic discharge from the wound which was controlled by antibiotics and prolonged recumbency. Indications for total hip arthroplasty in paralytic hips are rare and should be reserved for the most crippling conditions and one must be prepared fvr technical difficulties and a variety of complications with a prospecs for less than optimum results.

A histological and electron microscopic study were conducted in order to observe a morphological changing pattern of patellar ligament autograft after endoscopic ACL reconstruction. Seventeen patients among 117 consecutive series which underwent endoscopic ACL reconstruction from January 1990 to March 1995, were involved in this study according to the various follow-up periods. In second-look arthroscopic finding at 6 months follow-up after ACL reconstruction, reconstructed ACL was covered with synovium and round-shaped, and after the biopsy active bleeding could be seen. In histological study, 6 months follow-up, spindle or ovoid shaped fibroblast with hypercellularity, high crmp patterns of collagen fiber, and parallel arrangement of fibroblast to collagen fiber were noted. The cellularity of fibroblast decreased in according to periods of follow up. At 12 months follow up, spindle or ovoid fibroblast, its cellularity and arrangement pattern and crimp pattern of collagen fiber seemed to be almost similar to those of normal ACL. This similaryity continued up to 2 years and 2 months after reconstruction. In EM study, until 6 months follow-up after reconstruction, the graft showed randomly arranged fibroblasts with hypercellularity, which had abundant cytoplasm with marked irregular cytoplasmic borders and prominent nuclear indentation, Collagen fibrils were immature and showed a unimodel distribution with small diameter. At 12 months follow-up, elongated fibroblasts appeared, but these cells contained folded nuclei and abundant cytoplasm. Collagen fibrils had parallel arrangement and sparse cross striation, and comprised of mainly small fibrils and scattered large fibrils. After 24 months follow-up, the cellularity decreased more. The regular arrangement of collagen fibrils with wavy pattern similar to normal anterior cruciate ligament was noted. Two distinctive population of the small and large diameter of fibrils was also observed (bimodal distribution). At 26 months, the large and small collagen fibrils compresed a characteric bimodal pattern with parallel arrangement, but the majority of fibroblasts had irregular cytoplasmic contour, and abundant cytoplasm with increased organelles, which indicated the active function. These findings suggest that the graft are still immature even at 26 months in postoperative follow up despite considerable maturation of collagen fibril.
