Focal nodular hyperplasia (FNH) is a rare, benign hepatic tumor which was usually discovered incidentally by imaging procedure performed for some other reasons. FNH is typically asymptomatic and, it seldom bleeds. There is no evidence to support any relation with primary liver cancer. Accordingly, the preferred management is conservative, and excision is reserved for large symptomatic and complicated lesion, or when the diagnosis remains uncertain. Although many cases of FNH has been described to date in the other countries, only four cases of FNH has been reported in Korean literature. In the present report we describe a 7 cm sized asymptomatic lesion of FNH in a 23-year-old woman, that was disclosed by various kinds of imaging procedure. The left lateral segmentectomy was performed. The mass was firm and showed areas of localized growth of mature hepatocytes and septal fibrosis accompanied with marginal ductal proliferation, consistent with FNH. It also displayed an incomplete stellate architectual configration consisted of a central fibrous scar.

Transfollicular extrusion of sebaceous gland lobules was observed in a case of actinic keratosis and 2 cases of sebaceous hyperplasia. The patient of act.inic keratosis was a 44-year-old white man and the patients of sebaceous hvperplasia were a i3-year-old Korean girl and a 28-year-old Korean man. The sebaceous gland lobules located within the dilated infundibular area and partly between separated granular layers were intact and partly surrounded by keratin materjal. No histopathologic overlapping of sebaceous gland lobules was observed. We suppose that transfollicular ext,rusion of sebaceous gland lobules may not be artifact. but one of natural phenomena. But further study will be necessary to evaluate the significance of this peculiar histopathologic findings.

The long-term studies of total knee arthroplasty (TKA) have confirmed reliable relief of pain and maintenance of function. However there have been few generalized studies of factors influencing the results of TKA. We evaluated retrospectively 187 TKAs (137 patients) which had been performed between January 1987 and May 1995. The follow-up period was from one year to eight years (mean, 3 years and 8 months). There were 133 knees of osteoarthritis (OA), 43 knees of rheumatoid arthritis (RA) and 11 knees of other causes including septic knee sequelae. We considered the preoperative factors as age, sex, side (right or left), body weight, height, primary disease, flexion contracture (FC), further flexion (FF), range of motion (ROM) of joint, deformity of varus and valgus and pain score, muscle strength score, instability score, total knee score according to the knee rating scale of the Hospital for Special Surgery (HSS). We considered the clinical results as FC, FF, ROM, pain, muscle strength, instability, total knee score according to the knee rating scale of the HSS and the radiological results as Roentgenographic Evaluation and Scoring System of American Knee Society and radiolucent line more than 2mm in width. We evaluated the clinical and radiological results of TKAs followed up more than I year and analyzed the results based on above factors. The results were as follows: 1. The preoperative factors influencing final FC were not the primary disease and FC, but the FF and ROM. The preoperative factors influencing final FF and ROM were the primary disease, the FF and ROM. 2. The pain, muscle power, instability scores were improved but there was no significant factor influencing them. The HSS knee scores were higher in OA group than RA group postoperatively. 3. There was no preoperative factor influencing the complication, revision, the radiological results. The preoperative factors influencing the results of TKA were the FF, ROM and the primary disease.

Dermatofibrosarcoma protuberans(DFSP) is an uncommon recurrent soft-tumor of skin and is locally highly invasive and aggressive, although it rarely metastasizes. When possible, of the many treatment modalities, the surgical excision is indicated primarily. There are three surgical modalities, which are excision with undefined or conservative surgical margins, excision with wide surgical margins and Mohs micrographic surgery(MMS). And the classical standard surgery was the local wide excision with at least 3cm margin around the primary tumor and through the deep fascia. However recent studies has showed that MMS decreased the recurrent rate of the tumor, conserving the normal uninvolved tissue, and MMS is accepted as the first choice treatment modality of DFSP. Some studies reported that the margin of 2.5cm is necessary to clear the tumor in MMS. We present two cases of recurrent DFSP treated by Mohs micrographic surgery, one through 4-staged resection, the other, 3-staged resection of the tumor.

Agenesis of the right lobe of the liver is a rare anomaly which may be associated with stone diseases, portal hypertension, and other congenital anomalies. The radiological differential diagnosis includes lobar atrophy due to cirrhosis or hilar cholangiocarcinoma. We present a case of agenesis of the right lobe of the liver with characteristic clinical and radiological findings.

OBJECTIVES: The purpose of this study is to analyze the previously unreported effect of fetal sex on the fetal heart rate and to measure its magnitude in relation to the effects of other independent clinical variables. METHODS: Three hundred and seventeen pregnant women who were able to provide electronic fetal heart rate monitoring were evaluated. On the basis of fetal sex after birth, 167 pregnant women who delivered male neonate were for males group and 146 examples who delivered female neonate were for female group. We analyzed fetal heart rate data using the Catholic Computer Assisted Obstetric Diagnosis System(CCAOD). RESULTS: Female fetuses had significantly faster basal heart rate(140.51+/-12.43bpm) than male fetuses(137.64+/-13.68 bpm).(P=0.007) Percent acceleration time(PAT) increased significantly for males(6.10+/-4.00bpm), comparing to females(4.90+/-3.34bpm).(P=0.001) Also percent deceleration time(PDT) was significantly higher in male fetuses(7.50+/-8.70bpm) than female fetuses(6.18+/-7.70bpm).(P=0.039) But there was no differences in standard deviation(SD)(8.84+/-10.11bpm, 8.11+/-3.56bpm), long term variation(LTV)(80.38+/-62.79msec, 73.65+/-54.60msec), and short term variation(STV)(14.06+/-9.79msec, 13.33+/-12.32msec) between male and female fetuses. CONCLUSION: The fetal heart rate of female fetuses differ from that of male fetuses. Computerized linear analysis and nonlinear analysis of antepartum fetal heart rate will need to take into account the multiple factors that influence the fetal heart rate to identify precisely which pattern predict clinical outcome.
