The congenital dislocation. of the hip is a common congenital disease in the orthopedic field. It is well known that the early diagnosis and effective treatment is very important for the patient to provide a favorable function in the whole life. The Pavlik harness made an important contribution to the treatment of children before standing age. The authors report a clinical experience of 34 patients(35 hips) with congenital dislocation of hip who were treated with Pavlik harness at the Department of Orthopedic Surgery of Chonnam University Hospital. There were total 230 patients(237 hips) diagnosed as congenital dislocation of hip for 10 years from 1978 to 1987. Fifty-one patients(52 hips) of them were treated with Pavlik harness. Only 34 patients(35 hips) were included in this study excluding 17 patients(17 hips) because of inappropriate records or follow-up. The follow-up period ranged from 1 year to 6 years with an average of 2 years and 5 months. The results are as follows ; 1. The most patients were girls, comprising 33 girls and 1 boy. 2. The age of children was 124.6days in average ranging from 13 to 201 days. 3. Of the 35 hips treated with Pavlik harness, satisfactory reduction was obtsined in 30 hips(85.7%). For 5 failed cases, the authors performed closed reduction under the general anesthesia in 3 cases and open reduction in 2 cases. 4. The causes of reduction failure were impossible reduction in 3 cases, nonconcentric reduction in 1 case and repeated redislocation in 1 case. 5. The acetabular and metaphyseal-edge angle improved from the average 33 and 5.8 degrees at the first visit to the average 19.9 and 30.6 degree at the final follow-up (20.7 and 29.2 degrees in normal side). 6. When compared with the value of the 30 hips which were reduced successfully, the initial acetabular angle of 5 failed cases was similar but the metaphyseal-edge angle of them was very low. 7. There was no reduction failure in 27 hips which had metaphyseal-edge angle above 10 degrees. But 5 reduction failures were observed in 8 hips with below −11 degrees. 8. An avascular necrosis was observed in only one patient. In conclusion, the Pavlik harness proved to be a successful means in treating patients with congenital dislocation of hip under 7 months of age with particularly above −10 degrees in metaphyseal-edge angle.

We report herein a case of bowenoid papulosis, which developed on the groin, the shaft of the penis and left parietal area, of scalp in a 31-year-old male. Clinical features present as brown to brown-black papules and verrucous plaques ranging from 2 cm to 12 cm in diameter. Electron microscopic examination of the specimen obtained from our patient fail to reveal viral particles.

Chronic osteomyelitis with protracted clinical course and pretibial skin loss imposes on every orthopaedic surgeon as one of the most difficult problems to deal with. All the conservative treatment hitherto reported have left much to be revised and they often accompany, to the despair of both surgeon and patient, recurrence of the lesion. The authors have had the opportunity of treating such four cases, in which the extensive removal of sclerotic bone as well as soft tissue adjacent to the focus was done, and lo cover the defect thus produced, the soleus muscle transferred anteriorly, followed by skin graft. It proves to have been successful and the rationale to meet the wider clinical applicability of this procedure is described.

Core tissue for histologic study is believed by many pathologists to be more diagnostic than material from needle aspiration. Recently introduced automated biopsy gun simplifies core biopsies with increased quantity and quality of samples. Authors performed 38 percutaneous biopsies from 38 patients with 18G automated biopsy guns under US guide. Diagnostic target tissues were obtained in 33 biopsies(87%), inadequate tissues in 4 (11%), and adequate but not of target tissue in 1(3%). There was no major complication requiring treatment, but pain needing analgesics and pain with nausea/vomiting were experienced in 2 and 1 biopsies respectively. Average number of needle passes was 1.5(1-5) We concluded that US-guided gun biopsy was a easy and safe way to obtained tissue samples of good quantity and quality, especially useful in hospitals without constant availability of specialists in cytopathology.

M-mode, pulsed Doppler and Doppler color flow mapping, in addition to two-dimensional echocardiography, have greatly improved imaging of the fetal heart through identification of abnormal cardiac anatomy and rhythm in utero. The early detection of cardiac disturbance in utero permits alteration in obstetric management such as delivery in a high-risk center for optimal neonatal care and/or decision in optimal delivery time. We report two cases of the neonatal arrhy-thmia which were observed by fetal echocardiography. In the first case, female baby showed neonatal arrhythmias including tachycardia and brady-cardia until 3 days after birth, and then turned to bradyarrhythmia due to non-conducted atrial bigeminy. These events lead us to review the fetal echocardiographs of the patient carefully. Premature atrial contractions were observed in her fetal echocardiography. At 2 months after birth, the patient's electrocardiogram showed normal sinus rhythm. Severe neonatal bradycardia of the second case was due to congenital complete heart block, identified clearly by electrocardiogram after birth. This case also showed complete heart block in her fetal echocardiography. After insertion of the temporary pacemaker, cardiomegaly was improved. Both the neonate and the mother had positive anti-SSA/Ro autoantibody. But any other symptoms and signs of neonatal lupus did not appear in the neonate. Patient's mother also did not show any symptoms and signs of systemic lupus erythematosus. Since the prognosis depends upon the cause of bradyarrhythmia in fetus and neonates, differential diagnosis is important in obstetric management and optimal neonatal treatment.

The superior volume maintenance of membranous over endochondral bone grafts, which was shown in several studies has provided the basis for its preferred clinical use as an onlay grafting material on the craniofacial skeleton. The scientific rationale for this seeming embryological advantage, however, has never been proven, Since the cortical component of membranous bone is proportionally greater than that of endochondral bone, it follows that membranous grafts would show greater volume maintenance over time. Our hypothesis is that the pattern of onlay bone graft resorption is primarily determined by a graft's micro-architecture (relative cortical and cancellous composition) rather than its embryololgical origin(membranous versus endochondral). Fourty adult New Zealand white rabbits were used for this study. There were 8 animals in each of 4 groups. The rabbits of each group were sacrificed at 3, 8, and 16 weeks. Four types of grafts were placed subperosteally, onto each rabbit's cranium: a hydroxyapatite, a cortical bone graft of membranous origin, a cortical bone graft of endochondral origin and a cancellous bone graft of endochondral origin. Membranous bone grafts were obtained from the lateral mandible and endochondral bone grafts were obtained from the ileum. In order to determine post-sacrifice volume and density of the bone grafts, a caliper technique and bone densitometry(bone densitometer: LUNAR, DPX-L, U.S.A.) were performed on all of the bone grafts. Bone graft specimens were histologically examined at 3, 8, and 16 weeks.The measurement of volume and density show that there is a statistically greater resumption in the cancellous endochondral bone grafts for all parameter, compared to either the endochondral or membranous cortical bone grafts or hydroxyapatite at all time points(p< 0.05). In addition, there is no significant difference in the resorption rates between the endochondral and membranous cortical bone grafts for all parameters at all time points. By placing cortical bone grafts and cancellous bone grafts on the recipient sites separately, we have shown that the former grafts maintain their volumes, widths and projections significantly better than the latter grafts. Futhermore, we found no statistical difference in resorption rates between the two cortical bone grafts of different embryologic origins, a finding which has never been previously shown. Bone volume fraction, measured with bone densitometry, was shown to be higher in cortical bone than in cancellous bone at all time points, further illustrating the differences between cortical and cancellous bone.From our results, we believe cortical bone to be a superior onlay-graftiong material, independent of its embryololgic origin.
