The goal of total knee replacement is to relieve pain, to stabilize joint movement and to correct deformity. It is indicated for patients with rheumatoid arthritis, osteoarthritis and severe post-traumatic arthritis. The author analyzed 71 patients(106 cases), who received the PFC type of total knee replacement from August 1992 and the results were as follows; 1. Among the 71 patients, male was 8 patients and female was 63 patients whose average age was 56 years and average follow up period was 24 months, ranged from 8 months to 3 years 8 months. 2. Rheumatoid arthritis was the most common cause with 31 patients(56 cases) followed by osteoarthritis with 39 patients(49 cases). There was also one patient(1 case) that showed bony union of the knee due to old tuberculosis. The average duration of the illness was 12 years and the average weight of the patients was 57.7kg. 3. Flexion contracture decreased from an average of 21 degrees to 5 degrees after the operation. The range of motion increased from an average of 92 degrees before the operation to 117 degrees afterwards in cases of rheumatoid arthritis and decreased slightly from 108 degrees to 106 degrees in cases of osteoarthritis. 4. The tibiofemoral angle was corrected from an average 1.5 degrees varus before the operation to an average 6.7 degrees valgus after operation. Eighty seven percent of patients with rheumatoid arthritis showed valgus deformity and seventy eight percent of degenerative osteoarthritis patients showed varus deformity preoperatively. 5. Radiographically, the joint line position shifted an average 2.3mm in rheumatoid arthritis and an average 0.3mm in osteoarthritis. The component position, the femoral flexion was an average 89.6 degrees in the anteroposterior view, an average 87 degrees in the lateral view. 6. The thickness of the patella measured in the operating room of 61 cases was an average 21mm and after resection of patella, the remaining bone measured an average of 13.6mm. 7. To achieve soft tissue balance, 29 patients(33 cases) underwent medial stripping and 23 patients(30 cases) had patella lateral release. 8. The Insall Knee Rating Score was used to evaluate the results. The results were 69 cases excellent, 33 cases good, 3 fair and 1 poor. Ninety two percent of the patients had good or excellent results in average 24 months follow-up. 9. The complications consisted of one case of delayed deep infection, one case of patellar subluxation and one case of supracondylar fracture of the femur.

This study was conducted to evaluate the effect of PTSD on memory funtion and hippocampal volume, and to identify major variables correlated to hippocampal volume and memory function. Thirty four Vietnam veterans were collected for this study, among whom eighteen were PTSD patients and sixteen were combat control subjects. The author used Impact of Event Scale(IES), Combat Exposure Scale(CES), Hamilton Depression Rating Scale(HDRS) and Beck Depression Inventory(BDI). Korea Memory Assessment Scale(K-MAS) was assessed for memory function. Magnetic resonance imaging(MRI) was used to measure hippocampal volume. There were significant differences between PTSD and Non-PTSD veterans in IES, HDRS and BDI. Significant difference was found in verbal memory and total memory of K-MAS between PTSD and Non-PTSD veterans. There was significant difference in hippocampal volume between PTSD and Non-PTSD veterans. Short term memory, verbal memory and total memory were positively correlated to hippocampal volume. Hippocampal volume was negatively correlated to IES, HDRS, and BDI. These results suggest that PTSD severity be associated with hippocampal atrophy and memory dysfunction. Reduced or smaller hippocampal volume may be preexisting risk factor for stress exposure or the development of PTSD on combat exposure.

We report a case of morphea profunda in a 21-year-old male who had diffuse brown sclerotic plaques on his extremities. Laboratory findings showed peripheral eosinophilia and an increased titers for anti-DNA and anti-nuclear antibodies. Histopathologic findings showed diffuse fibrosis and a thickening of the lower dermis and subcutaneous tissue. He has been treated with hydroxychloroquine 400mg per day and the sclerosis of the skin improved.

A clinical observation of the nail pigmentation change was made on 200 patients receiving cancer chemotheray who were seen at; the Department of Internal Medicine, Seoul National University Hospital, from January through May, 1986. The results were as follows: l. Among the 200 patients, 118 cases(59%,) showed nail pigmentation changes. 2. The patterns of nail pigmentation change were as follows: Parallel transverse band(70 cases 59.3%), longitudinal pigmentated band(32 cases, 27. 1%), brown arc(25 cases, 21. 2%), Proximal black pigmentation(10 cases, 8. 5%), diffuse pigmentation(5 cases, 4.2%), parallel transverse white line(5 cases, 4.2%), half and half nail(3 cases, 2. 5%), pigmentations with transverse white band(1 case, 0. 8%). 3. Various cambinations of nail pigmentation pattern were found in 33 patients (28. 0%). 4. 11 cases of the nail dystrophy with nail pigmentation change were observed: Longitudinal ridge(7 cases), transverse groove(3 cases), wavy transverse fissure (1 case).

A clinical observation of cutaneous complications was made on 200 patients receiving cancer chemotherapy at the Department of Internal Medicine, Seoul National University from January through May, 1986. The results were as follows: 1. Among the 200 patients, 191 case(95. 5%) showed cutaneous complications 2. The cutaneous complications included the following; hyperpigmentation(14l cases, 70. 5%), alopecia(138 cases, 69.4%), nail change(118 cases, 59.0%), mucositis(47 cases, 23.5%), dryness of the skin(40 cases, 20.0%), seborrheic dermatitis(24 cases, 12. 2%), increase of seborrheic keratosis(11 cases, 5.6%), folliculitis or acneiform eruptions(9 cases, 4,5%), melasma(6 cases, 3.0%), gynecomastia(3 cases, 1.5%), vessel hardening or dimpling(3 cases, 1.5%), radiation recall(2 cases, 1.0%), hyperhydrosis(2 cases), photosensitivity(1 case, 0.5%), tissue necrosis(1 case), facial flushing(1 case), purpura(1 case) and obesity(1 case), 3 Steps were taken to determine the chemotherapeutic agents causing these cutaneous complications, though in some cases it was difficult in determining exaetlr which chemotherapeutic agent was the cause of the observed cutaneous complication.

Adenoma of the nipple is a benign tumor of the lactiferous ducts of the nipple which frequently causes erosion of the surface. It can clinically mmic Paget's disease and histologically be misdiagnosed as a well-differentiated adenocarcinoma. A 20-year-old woman developed an erythematous oozing patch on the right nipple two years ago, which subsequently developed iiito verrucous surfaccd papules. A biopsy specimen of the lesion showed focal acanthosis of the epidermis. The tumor was composed of fairly well-circumscribed, glandlike structures within the nipple stroma. Ductlike struciures, papillary areas, solid nests of cells and cysts lined by squarnous epithelium, could be seen, Two cell types lining the ducts were recognized; inner columnar cells and peripherally located cuboidal cells. Although simple excision of the adenoma is the treatment of choice, our case was treated successfully by electrucoagulation.

We analysed the results of total knee replacement arthroplasty without patellar resurfacing in 20 patients(28 knees) retrospectively. The patella was not resurfaced when it maintained relatively healthy cartilage in osteoarthritis or the patella was too thin to be replaced in rheumatoid arthritis. The diagnoses were osteoarthritis in 11 and rheumatoid arthritis in 17 cases. The follow up period was 30.3 months in average(12-70 months). A lateral retinacular release was performed in 22 knees(78.6%). The mean knee society score improved from 45.4 preoperatively to 84.1 postoperatively and the functional score improved from 21.4 preoperatively to 63.3 postoperatively. The modified Kujala score was 43.2 points in osteoarthritis and 43.6 points in rheumatoid arthritis. We conclude the total knee replacement arthroplasty without patellar resurfacing shows good results, without high risk of postoperative peripatellar complication.
