PURPOSE: In order to know the clinical usefulness of the Bioscrew(Linvatec, USA) and the Semi-Fix (Arthrex, USA) technique for femoral fixation in ACL reconstruction using hamstring double loops, we scrutinized and compared the 24 knees. Materials and Methods: We compared Lysholm score, Hospital for Special Surgery(HSS) knee rating scores, Lachman tests, Pivot-Shift tests and KT side to side difference in 24 knees after arthroscopic ACL reconstruction using hamstring double loops from August 1996 to January 1998. We have used fourteen bio-absorbable interference screws and ten Semi-fixs for femoral tunnel fixation. RESULTS: We took the data; the Lysholm score of 96.1 and 94.1; HSS score of 98.6 and 98.1; KT differ- ence of 1.3 +- 2.13(mm) and 1.2 +- 1.89(mm) after ACL reconstruction using Bioscrew or Semi-Fix respec- tively. Femoral tunnel enlargement showed 2.51 +- 1.03(mm) and 1.95 +- 2.33(mm) respectively. And we got the similar results of Pivot-shift test, Lachman test and anterior drawer test after reconstructive surgery. CONCLUSION: Since we got the similar good data in comparative clinical study between the Bioscrews and the Semi-Fix technique, we anticipatd that either the use of Semi-fix technique or the biodegradable interference screws would be bright in the fixation to femoral tunnel in ACL reconstruction using ham- string double loops.

Nine strains (6%) were confirmed as resistant (MIC=20ug/ml) to methicillin (MT) among 150 isolates of staphylococcus aureus. These MT-resistant staphylococcus aureus (MRSA) strains were also turned out to be more less resistant to other antibiotics tested, such as penicillin, chloramphenicol, tetracycline, and gentamicin except for cephaloridine. It was noteworthy, however, that strain MRSA 5 showed a relatively susceptible attitude toward most of the antibiotics tested, while being extremely resistant to MT only. Salt (NaC1) containing (5-3%) media did not have any significant effect on the degree of MT-resistance of MRSA strains. There was, however, such a tendency as that by the addition of salt the degree of MT-resistance was lowered in the highly MT-resistant strains while enhanced in MT-susceptible ones. It was confirmed that penicillinase did not have any effect on the MT-resistance while most of the penicillin- resistant strains produced the enzyme.

The present study was carried out to investigate the HHsAg in the normal skin, dis- eased skin and skin specimens of window period of HBsAg positive patients in their serum with normal liver function. This study was done by immunoperoxidase techniques using the monoclonal antibody to hepatitis E3 surface antigen and by electron microscopy. Immunoperoxidase staining was dane on twenty specimeris of normal skin Group .D twenty specimens of diseased skin (15 cases of dermographism, 2 cases of purpura, 1 case of follicuht,is and 1 cases of morbilliform eruption) (Ciroup II ) and three specimens of normal skin af window period (Group III ) of HBsAp positive patients in their serum. Twelve cases of Group I, eleven cases of Group IL (1(J cases of dremographism and 1 rase of purpura) and two cases of Group II were stained positively for HBsAg. Positive sites were keratinocyte of epidermis, sweat gland, blood vessel and hair follicle. Electron microscopy failed to reveal viral particle, The above resuts suggest the possibility of transmission of viral hepatitis B thraugh the skin and skin appendages.

Experimental osteoarthritis has been studied by various methods such as local compression of the joint, immobilization of the joint, relief of the contact and incision of the meniscus. The instability caused by the ligament injuries of the knee joints of the rabbits induced degenerative changes of the articular cartilages. After excision of the medial collateral ligament, medial meniscus and both cruciate ligament, the articular cartilages were observed serially after 1, 2, 3, 4, 6, 8, 10 and 12 weeks, grossly and microscopically. The results obtained are as follows; 1. Loss of transluscency and luster was observed even in the early group of the first week, and was followed by erosion and fissure on the articular cartilage in the groups of the third and later weeks grossly. 2. Microscopically, cluster formation of the chondrocytes on the articular cartilage was observed in the group of the first week and there was tendency of increase in its numbers and extents in the subsquent groups. Fibrillation and cleft formation was also observed in these groups. 3. Loss of metachromasia was observed in the groups of the second and subsquent weeks, but it was most prominant in the groups of the sixth and eighth weeks. 4. The tendancy of cluster formation was more prominent, compared with those of fibrillation or erosion.

Nickel is widely known throughout the world as a common source of contact dermatitis. Korea is one of the rapidly developing countries where the use of nickel and nickel by-products is on the rise. Lacking in ore, Korea imports most of its nickel. In the last ten years, in relation to rapid industrial development, the amount of nickel imported has increased over 1, 000 times. Nickel dermatitis is becoming an increasing problem in the patch test clinic. With regards to this, we have tried the dimethylglyoxime spot test to all materials mentioned in the textbooks which are regarded as nickel sources in other industrialized societies, so as to make an up-to-date list of nickel sources applicable to Korea. In addition, we have also included traditional nickel sources such as acupuncture needles, fire pot, old and new coins and chest of drawers etc. We also have analyzed data concerning nickel imports to Korea during the past 10 years.

The brief report of Zeisler (1922) of a pregnant woman with scattered telangiectasia in a unilateral distribution is perhaps the first recorded case of this syndrome. The syndrome has been described in association with pregnancy, puberty, alcoholisrn and cirrhosis, hormonal therapy and congenital status. The authors observed in a 17-year-old male unilateral telangiectatic lesions over the left C, C, C, Tl and T, dermatomal regions. The lesions developed at first at his puberty on the anterior part of the chest as speckled bright red discoloration. Thereafter, the lesion has been progressed to involve the left upper extremity, sholder, upper middle part of the chest, eventually. Family history was negative and physical, lahoratory and X-ray examination were all negative or within normal limit. No mucous membrane involvement was observed. On histopathologic examination of the skin lesion, thin walled ectatic vessels lined with single layer of endothelial cells were observed in the upper dermis. The lesions were partly dermabrased with favorable result.

Antiseptics are substances that kill or prevent the growth of microorganisms when applied to living tissue. They must be effective against microorganisms but must also retain their activity in presence of body fluids without being harmful locally or systemically. Among many antiseptics, Betadine(R) has been widely used because of its low toxicity and high germicidal efficacy. We reported 2 cases of allergic contact dermatitis to Betadine(R) in surgical patients. They had eczematous eruption along the Betadine(R) applying sites. Path tests Betadine(R) confirmed the diagnosis.

The microform cleft lip is the mildest expression of cleft lip and nose deformity, but it has no specific definition, classification, and few methods have been reported for its correction. It is characterized by deformity of the nostril, skin striae of the upper lip, notching of peaked Cupid's bow, deformity of the vermilion, and anomaly of the upper lateral incisior and alveolar ridge on the affected region. Sixty-three microform cleft lip patients were operated on between Dec. 1993 and Sep. 1998 in our department(29 males and 34 females). The age of the patients ranged from 5 months to 30 years(Mean 9 years). We classified and treated the microform cleft lip as follows: Class I: Cleft lip nose with very slight lip deformity Class II: Minimal lip deformity without vermilion notching Class III: Mild lip deformity with slight vermilion notching. The goals in the correction of a microform cleft lip are to obtain an esthetically pleasing upper lip and nose, and to reestablish muscle continuity for improved function. To attain these goals, we used the above classification and satisfactory results were obtained by treating the microform cleft according to the classification.

Pigmented contact dermiatitis is a disease resulting from recirrent contact dermatitis due to hypersensitivity to cosmetic components, which produces secondery bizarre dark brown hyperpigmentation. Histological examinaition of this condition reveals liquefaction degeneration of the basal cells of the epidermis and melanopbages in the upper dermis. We report a case of pigmented contact dermatitis from musk tibeten, which was diagnosed by the histological examination, the patch and photopatch tests. Residul hisperpigmentation was seen on the region of the patch testing.
