We report herein two cases of leukemia cutis. One case is a 54-year-old woman who came to our department with complaints of a solitary ulcerating nodule on her left leg that had been present for 2 months since prior to her visit. Through histopathological studies, the diagnosis of myelocytic leukemia cutis was made before the final diagnosis of acute myelocytic leukemia was made by hematological studies. When combined chemotherapy was finished, she was in a partial remission state and the nodule disappeared after 1 month of chemotherapy. The other case is a 77-year-old man having multiple infiltrative nodules on the right forearm and right thigh for 1 month prior his visit. He was diagnosed as having leukemia cutis for his skin lesions histopathologically. This was redefined as chronic myelomonocytic leukemia of the myelodysplastic syndrome with blastic transfor- mation by hematological examination. He developed septicemia and died 3 weeks after the dermato- logical diagnosis.

OBJECTIVE: This study was designed to evaluate whether maternal serum human chorionic gonadotropin(hCG) level measured during second trimester could be used as a predictor of pregnancy-induced hypertension. METHODS: Between March 1996 and November l997, 505 pregnant women undergoing second trimester(14-22 weeks of amenorrhea) triple marker screening for neural tube defect and Down syndrome who delivered at our institution were reviewed. All samples were assayed in the same laboratory and medical records were reviewed about medical and obstetrical history. RESULTS: Maternal serum human chorionic gonadotropin level(multiples of the median, MoM) was significantly higher in the pregnancy-induced hypertension group than in the control group. With the use of 2. l multiples of the median as a cutoff value, the sensitivity of human chorionic gonadotropin as a screening marker for development of pregnancy-induced hypertension was 38.7%, the specificity was 95.9%, positive predictive value was 38.7% and negative predictive value was 95.9%. Conlusion: We suggest that second trimester maternal serum human chorionic gonadotropin levels can be used clinically as an early predictive marker for pregnancy-induced hypertension.

Marjolin is ulcer may be defined briefly as a cancer arising in a bum scar. A 41-year-old female had a Marjolin is ulcer(12x10x3cm) on her right lower leg. This ulcerated tumor has been present for two and half months and the induction period sinnc her bum was 29 years. The pathologic diagn.osis was squamous cell carcinoma, grade 2. Roentgenograms of her right lower leg revealed several soft tissue masses densities which, in part, horizontally connected with the periosteum of the tibia. So she was treated by above-knee amputation with dissection of several, unenlarged inguinal nodes which showed no evidence of metastases. She developed large, single, fixed metastatic node in right inguinal area one month after amputation and dissection was done.

Total hip arthroplasty(THA) is applied to various hip diseases, and the results are different according to the disease entities. We have made the functional evaluation of three groups of the patients who had undergone THA in Seoul National University Hospital from 1981 to 1990: the first group-fused hips (28 hips of 27 patients), the second group partially ankylotic hips whose total range of motion were less than 60°(46 hips of 46 patients), and the third group-hips of ankylosing spondylitis (22 hips of 14 patients). The results were summerized as follows: No statistically significant difference was seen in the postoperative average Harris hip score between three groups. In the postoperative average range of motion, statistically significant difference was seen only between the first and second groups. Therefore, similar clinical results can be obtained from the THA in the fused hips to those of the partially ankylotic hips such as tuberculous or septic hip sequelae.

Since 1983, the transtrochanteric rotational osteotomy has been performed in 38 hips of 36 patients for the nontraumatic avascular necrosis of the femoral head at the department of orthopaedic surgery of Seoul National University Hospital. Out of them, 26 hips(18 cases of Sugioka grade I and 8 cases of Sugioka grade II ) were followed up for more than 1 year. The average period of follow-up was 3 years and 5 months(range, 1 year and 2 months to 7 years). These cases include 3 cases of failure before 2 years after operation. Overall, the result was satisfactory in 20 cases(77%)out of a total of 26 cases(success in 18 cases(69%)and good in 2 cases(8%)). The results of the grade I lesions(14 cases of success and 1 case of good result out of 18 cases) were better than those of the grade I lesions(4 cases of success and 1 case of good result out of 8 cases). Complications occurred in 5 cases. These include an ectopic ossification, a stress fracture of the neck, a nonunion of the osteotomy site, a nonunion of the greater trochanter and a delayed union of the greater trochanter. There were 6 cases of failure. For the 4 cases of them, hip replacement arthroplasy was performed. The MRI images axial to the longitudinal axis of the femoral neck gave excellent information for the operation.

Although the incidence of tuberculous arthritis of the hip is being decreased with improvement of hygiene and preventive measures and chemotheraphy, it remains as important disease in orthopedic surgery. In order to evaluate which treatment is best in the view of eradication of the tuberculosis and preservation of the function, seventy two patients of tuberculous arthritis of the hip who were treated at the Department of Orthopedic Surgery, Seoul University Hospital for periods of 14 years between January 1970 and August 1983 were analysed clinically. The results are as follows: 1. Age distribution showed that patients below 15 years were thirty (41.7%) and those above 16 years were forty two (58.3%). 2. Onset of the symptoms above 1 year occupied forty two patients (58.3%). 3. Duration of follow up is between 1 year and 14 years with average duration of 3.5 years. 4. Recurrence rate according to the modality of treatment was 12.9% as 4 cases among 31 cases of hip fusion group, 15,2% as 5 cases among 33 cases of synovectomy group, and 28.6% as 2 cases among 7 cases of conservative group. 5. Follow up of the functional evaluation of the hip was 92.9% of “above Fair” as 26 cases among 28 cases of synovectomy group, 60% of “above Fair” as 3 cases among 5 cases of conservetive treatment group, and 25.7% of “above Fair” as 9 cases among 35 cases of hip fusion group. 6. Although the recurrence rate of synovectomy group is a little higher than that of hip fusion group, synovectomy is a better treatment in the view of the preservation of the function of the hip considering Korean life style.

BACKGROUND: Specified clinical observations regarding skin changes in viral hepatitis have not yet been accomplished in Korea, especially in view of serotypes. OBJECTIVE: This study was conducted to identify various cutaneous manifestations of viral hepatitis according to viral serotypes and the stages of the disease. METHODS: We performed a clinical observation of cutaneous manifestations in 450 patients who were diagnosed with viral hepatitis. RESULTS: 1. Cutaneous manifestations were found in 383(85.1%) patients. Patients with a longer duration seemed to have skin lesions more frequently. 2. The frequency of cutaneous manifestations was highest in HAV(94.4%) and HBV(84.9%) serotypes. The most common cutaneous manifestation was pruritus(32.4%) in all studied subjects. In HBV hepatitic patients, the most common cutaneous manifestation was pruritus(35.4%), in HCV hepatitic patients, vasculitic purpura(74.5%), in HAV hepatitic patients, urticaria(88.8%), in the hepatitic patients with the mixed form, spider angioma(30.2%) and vasculitic purpura(30.2%). 3. Urticarial lesions in non-HCV hepatitis were of the lymphocytic vasculitis type but HCV hepatitis was associated with neutrophilic vasculitis. The purpuric lesions with HCV hepatitis were of the neutrophilic vasculitis type while lymphocytic vasculitis was present in non-HCV hepatitis. 4. The most severe pruritus was present in HBV hepatitic patients. CONCLUSION: The cutaneous manifestations in viral hepatitis have different clinical features depending on the viral types.

INTRODUCTION: In this study, we compared sleep structure, EEG characteristic of pediatric obstructive sleep apnea (OSA) and normal controls which were matched in sex and age. METHODS: Fifteen children (male:female=4:11) who complained snoring and were suspected to have sleep apnea and their age and sex matched normal controls (male:female=5:10) have been done nocturnal polysomnography (NPSG). Sleep parameters, sleep apnea variables and relative spectral components of EEG from NPSG have been compared between both groups. RESULTS: Pediatric OSA group were distinguished from normal controls in terms of apnea index, respiratory disturbance index and nadir of oxyhemoglobulin desaturation. Pediatric OSA group showed increased percent of sleep stage 1, decreased rapid eye movement sleep percent and increased delta power in O1 EEG channel. However other sleep parameters and spectral powers were not different between two groups. CONCLUSION: In pediatric OSA group, sleep structure parameter disruption may be not prominent as the previous studies for adult OSA group because of including mild OSA data in diagnostic criteria. In addition, EEG changes might not be distinct due to low arousal index compared to adult OSA patients. We can observe general characteristics and particularity of pediatric OSA through this study.
