A retrospective review was performed in 33 knees of 30 patients who had undergone arthroscopic debridement for degenerative osteoarthritis of the knee. The mean age of the patients at operation was 55 years and the mean follow-up after operation was 15 months. We divided the knec:s into 2 groups; meniscectomy group (23 knees) and non-meniscectomy group (10 knees). The preoperative radiographic findings were divided into 3 groups according to the classification systern by Lotke et al. The postoperative results were evaluated using the nine-point scale by Baumgaertner et al. Our study was conducted to: 1) assess the overall efficacy of arthroscopic debridement, 2) compare the results between the. Meniscectomy group and nonmeniscectomy group, and 3) identify the relationship between the preoperative radiographic findings and out- come at the final follow-up time. Overall excellent or good results were ac.hieved in 22 knees (67%) and the preoperative radiographic findings correlated with the outcome at the final follow-up time. But the results in the meniscectomy and non-meniscectomy poups showed no significant differences statistically. We believe that arthroscopic debridement is an effective option of treatments for mild I:o moderate degenerative arthritis of the knee after failure of conservative measures.

It is well known that the merit of total hip replacement is to provide rather satisfactory range of motion with relief of pain among reconstructive procedures. Therefore it is presumed that the ankylosed hip could gain range of motion by reconstruction of artificial joint, it the muscles around the hip is adequate. Furthermore when the patient has some problems in the back or knee secondary to ankylosed and deformed hip, any kind of reconstructive surgery, maybe total hip replacement is necessary which gives range of motion and correct deformity of the hip. Our result total hip replacements for fifteen ankylos d hips of twelve patients that were followed more than one year is gratifying to all patients with relief of pain and relatively satisfactory range of motion.

Total hip replacement arthroplasty has become an established procedure in the management of painful arthritic hip in past two decades. However there is no many reports that concern follow-up study in total hip replacement arthropiasty. This is a follow-up study in 100 total hip replacement arthroplastics in 86 patients of 157 total hip replacement arthroplasties in 135 patients, performed at the Department of Orthopedic Surgery, Seoul National University Hospital, between November 1973 and December 1979. The longest fallow-up was 5 years and the shortest 6 months, the average being 2 years and 6 months. 1. There were 54 males (63%) and 32 females (37%). 2. The underlying diseases of 100 hips were avascular necrosis of 35 hips, septic hip residua of 31 hips, primary osteoarthritis of 9 hips, old hip fracture of 9 hips, Legg-Perthes disease of 7 hips, rheumatoid arthritis of 5 hips, congenital dislocation of 3 hips, and failed endoprosthesis of 1 hip. 3. The types of prosthesis used were Muller ones in 82 hips, T-28 in 17 hips, and Charniey and Harris type one case respectively. 4. In the half cases of a hundred total hip replacement arthroplasties, the anterolateral or posterolateral approach was used without trochanteric osteotomy. 5. Postoperative complications were as follows: 13 cases of wound problem including 3 early deep infections, 2 dislocations, 1 femoral nerve palsy, 3 peroneal nerve palsies, 1 acetabular perforation, 2 femoral shaft perforations, 14 trochanteric problems including 11 cases of wire breakage, 2 nonunions, and 3 cases of trochanteric bursitis 3 ectopic ossifications, 3 cases of radiological loosening including 2 femoral and 1 acetabular. 6. The range of motion were improved from 28 to 5 of flexion contracture, from 91 to 101 of further . flexion, and from 16 to 48 of abduction in the average. 7. The improved ranges of motion were varied with disease group rather than type of prosthesis and the length of neck of prosthesis. 8. The function of each hip was evaluated preoperatively and postoperatively by the method of Harris and d'Aubigne, and improved from 55.3 and to 88.2 by Harris score and from 11.2 to 15.8 d Aubigne respectively.

Intravascular papillary endothelial hyperplasia is a relatively rare benign tumor, which is charaterized by the development of endothelial-lined papillary projections in a vascular lumen. They can occur as a pure form in which endothelial proliferation developes in a dilated vessel, a mixed form in which endothelial proliferation occurs within a pre-existing angioma. We herein report a case of intravascular papillary endothelial hyperplasia coexistent with angioleiomyoma occuring in a 54-year-old man, who had a slowly growing tumor on the right sole for 2 years. The histologic findings revealed a solitary encapsulated mass composed of smooth muscles and blood vessels in deep dermis and papillary endothelial hyperplasia in a neighboring blood vessel.

A review of the literature, provided by a MEDLINE search from 1980 through June 1999, was performed. This study was screened that 649 patients received 679 sinus lift grafts in which 2056 implants were placed. The types of grafts in sinus augmentation were autogenous bone, corticocancellous block bone, allogenic bone, and a variety of alloplastic materials. Results of these grafts are presented. The most frequent complications was the infection of maxillary sinus. Long-term follow-up is necessary to advance the sinus elevation and to support posterior maxillary restorations.

PURPOSE: Antenatal steroid(ANS) therapy in premature infants is an effective therapeutic strategy in reducing the incidence of respiratory distress syndrome, intraventricular hemorrhage, necrotizing enterocolitis, and patent ductus arteriosus. For premature infants to gain improved survival, adequate weight loss during early postnatal days and maintenance of electrolyte balance is important, however, it is uncertain that ANS affect them. We hypothesized that ANS augment fluid and electrolyte balance and dinical outcome of very low birth weight(VLBW) who had received restricted fluid regimen. METHODS: Mechanically ventilated VLBW infants who survived over 30 days were selected. We reviewed medical records to compare weight loss, urine output, electrolyte concentration, blood pressure during five days of life and clinical outcome between premature infants who received ANS(n=15) and who were not(n=58). RESULTS: Gestational age, birth weight were similar between two groups. Volume of administered fluid, urine output, and initial weight loss during first five days of life were similar, however, weight loss on postnatal day five were lower in study group than control group(p=.039). Blood pressure, serum sodium concentration, serum potassium concentration, and urine specific gravity were similar between two groups. Incidence of respiratory distress syndrome was lower in study group(20%) than control group(48%)(p=.041), however, incidence of sepsis were greater in study group(33%) than control group(7%)(p=.029). CONDUSION: ANS did not affect fluid and electrolyte balance of very low birth weight(VLBW) infants who had received restricted fluid regimen. ANS decreased the incidence of respiratory distress syndrome in this population, however, increased the incidence of sepsis.

Porokeratosis is a specific disorder of keratinization characterized histologically by the presence of a cornoid lamella. Clinically, the basic lesion is a sharply demarcated hyperkeratotic plaque which may be linear, punctated, or annular with central atrophy. The etiology of the various types of porokeratosis is unknown. However, heredity, UV radiation, immunosuppression, trauma, burns, and occult infection are known to be precipitating or exacerbating factors. A 32-year-old female was burnt on her right arm and chest at the age of 12. Several years later, brownish plaques developed in these burn areas. Seven years prior to visiting our clinic, nu- merous match-head sized, peripherally elevated macules developed on the forearms and have gradually spread to the other areas of her upper and lower extremities. The histological findings of two lesions from the burn areas showed the same features including cornoid lamellae in the epidermis and fibrosis in the dermis. Howerer, the histological finding of a lesion from a non-burn area showed cornoid lamellae in the epidermis without evidence of dermal fibrosis. We believe our case is the first to be reported in Korea in which porokeratosis arose in previous burn areas.
