This study was performed to evaluate histopathologic and physical characteristics of anterior capsule during capsulorhexis with a new high-frequency diathermy.The authors investigated the histopathologic characteristics of anterior capsule according to coagulation time and anterior capsular diameter in diathermy capsulorhesxis(DC),comparing with those in continuous curvilinear capsulorhexis(CCC). Thermally induced histopathologic alter-ation was localized at anterior capsule with coagulation for 0.5 second, while it was extended into cortex with coagulation for 2 seconds.When capsulorhexis was performed with diameter of 6 mmand the margin was pulled with iris retractor,anterior capsular edge was fully extended both in CCC and DC.But with diameter of 3.5 mm,DC mostly led to tear of capsular edge on its extension,while CCC permitted full extension of anterior capsular edge.These results suggest that strength of anterior capsular edge in DC is inferior to that in CCC.However diathermy capsulorhexis is a useful alternative technique in cases,which CCC is difficult to perform,such ashypermature or congenital cataracts.

OBJECTIVE: To evaluate the current status and new trends in gynelcological pelviscopy in Korea. METHODS: A survey was conducted and analyzed based on 20997 cases of operative pelviscopy hom May, 1985 to February, 1998 reported from twenty four university hospitals in Korea. RESULTS: The results obtained were ss followings; 1) 45.9 % of the total cases was 30 to 39 years old age group and it was the most dominant age group, 2) The previous operative history was found in 10.9% of the tota1 cases and included cesarean section(30.0%), ectopic pregnancy(20.3%), etc. 3) The operative indications were diagnostic(26.2%), myoma uteri(23.1%), ectopic pregnancy(21.4%), adnexal mass(18.4%), etc. In cases of diagnostic indication, the most common post-operative diagnosis of pelviscopic surgery was tubal pregnancy(30,6%). 4) The operative titles were salpingectomy(25.1%), hysterectomy(19.9%), salpinghorectomy(19.8%), etc. 5) The complications of operative pelviscopy were composed of subcutaneous emphysema(0.58%), preperitoneal bleeding(0.3%), bladder injury(0,3%), bowel injury(0.3%), etc. 6) lhe survey showed that 57.1% of the respondents desired more than 1 year of period for well peration between the operator and the assistant. 56.7% of respondents indicated that the surgical technique of the operator was the most important factor for a successful pelvisocopic surgery. 7) The most beneficial effect of the pelviscopy included the comfortableness of the patient(40.0%), cosmetic effect(22.8%), decrease of complications(14.2%), etc. CONCLUSION: The modem methods of operative pelviscopy have been successfully used in the treatment of gynecological disease. Today, pelviscopic surgery is being applied in almost all the cases of gynecological disease. Hence, the majority of pelviscopy techniques and pracedures being performed by surgeon must be taught in the controlled setting of a residency or a fellowship training program.

Pyogenic arthritis remain a difficult problem, despite the availability of a wide range of powerful modernantibiotics. Early and correct diagnosis is imperative to assure the prompt initiation of an effective therapeuticregimen and the prevent of late sequela. Careful clinical, laboratory and roentgenological analysis arefundamental to early and precise diagnosis. Therefore, plain roentgenogram shold not be overlooked. A radiologicaland clinical observation was made in 51 cases of pyogenic arthritis admittted to Chosun University Hospital duringthe period from January 1976 to Dec. 1983 and following results were obtained. 1. Among the 51 cases, 36 cases(70.6%) were male and 15 cases(29.4%) were females. The most prevalent age was 5 to 9 (27.6%). 2. Symptom durationless than 5 days was in 21 cases (41.2%) and more than 31 days was in 6 cases (11.7%). 3. The most common symptomon admission was pain around the involved joint and others are limitation of motion, swelling, tenderness, fever,local heating and erythema. 4. The underlying causes were composed of unknown in 21 cases(41.2%), trauma in 18cases(35.3%), infections focus in 8 cases (15.7%) and iatrogenic reasone 4 cases(7.8%) 5. The msot commonlyaffected joint was hip joint (45.1%). The other affected sites in order of frequency were knee, ankle, shoulder,S-I and elbow joint. In infants and children, hip and knee joint are commonly affected; In adults, knee joint ismost commonly affected. 6. In laboratory findings, the number of W.B.C and E.S.R were increased in 56.9%. Symptomduration more than 31 days in 5 cases were increased E.S,R only. Causative microorganism was isolated in 31 cases;the most common microorganism was Staphylococcus auterus in 22 cases. Others are B-hemolytic Streptococcus,Enterobacteriaceae species and Pseudomonas aeruginosa. 7. In 26 cases(50.9%) of the patients, roentgenographicfinding was negative. The most common radiological findig was soft tissue swelling and the others are include inorder of frequency: joint space widening, small erosions in articular cortex, subchondral osteoporosis. The comonradiological findings of symptom duration more than 31 days in 6 cases were lost of entire cortex, ankylosis andjoint space narrwoing.

OBJECTIVES: Early diagnosis of intrauterine growth retardation is important to ensure optimal monitoring and delivery with the introduction of real-time and Doppler ultrasound systems, a noninvasive method of measuring human fetal blood flow has become available. The aim of this study is to compare blood flow velocity waveforms at the fetal descending aorta and umbilical artery in normal and in patients with pregnancy induced hypertension. METHODS: Using a combination of linear array real-time and pulsed Doppler ultrasound, blood flow velocity measurements were carried out at the fetal descending aorta and umbilical artery in 35 normal pregnancies and 18 cases of pregnancy induced hypertensive patients. RESULTS: The mean systolic/diastolic ratio of umbilical artery and aorta was significantly higher in PIH patients than in normal pregnancies(3.8 +/- 0.81 versus 2.97 +/- 0.52, p<0.05) and to predict perinatal morbidity, umbilical velocimetry is more sensitive than that of descending thoracic aorta. CONCLUSION: This study suggests that umbilical artery velocimetry could be used as a marker to predict adverse perinatal outcome.

Endometriosis is a common, benign, and chronic gynecologic disorder. It is an Estrogen dependent disease that can cause pelvic pain, dysmenorrhea, and infertility. GnRH agonists, Danazol, progestogens, and oral contraceptives have been conventionally used for the medical treatment of endometriosis. Increasing knowledge about endometriosis has introduced more new targeted agents for endometriosis. Further study might be required to evaluate effectiveness and safety of new agents.

OBJECTIVE: This study is proposed to examine the relationship between bone loss after hormone replacement therapy for one year and initial bone markers. METHODS: One hundred postmenopausal women were studied for one year. At first visit, measurements were made of bone mineral density(BMD) at the lumbar spine and femoral neck, and of serum osteocalcin and urine deoxypyridinoline. After hormone replacement therapy was done for one year, BMD was rechecked. RESULTS: Serum osteocalcin was correlated with the rate of bone change(r=0.150, 0.262) and urine deoxypyridinoline was weakly correlated(r=-0.003, 0.038). The changes of femoral BMD in women with higher concentration of osteocalcin and deoxypyridinoline were significant different from those in women with normal concentration. At the lumbar spine, no significant differences were showed. In women with higher concentration of osteocalcin, the incidence of subjects with increased spine BMD was increased up to around 71.1%, which showed not significant increase compared with normal concentration of osteocalcin. And the incidence of increased spine BMD in women with higher concentration of osteocalcin was marked increased compared with the incidence of normal concentration. The level of the osteocalcin with increased spine BMD was 11.5+/-6.6 ng/ml, and the level with decreased spine BMD was 9.2+/-4.7 ng/ml, respectively. And the level of the deoxypyridinoline was 7.2+/-4.2 pmol/ mol cr in women with increased spine BMD and 7.2+/-2.7 pmol/ mol cr in women with decreased spine BMD, which was not statistically different. The concentration of deoxypyridinoline with increased and decreased in BMD in spine and femur was not statistically different. but the concentration of osteocalcin was 12.2 +/-5.5 ng/ml in significantly increased in BMD and 8.5 +/-4.5ng/ml in significantly decreased in BMD, which was showed significant different. CONCLUSION: Present study indicates that the serum osteocalcin more reflcets bone turnover changes at the menopause than deoxypyridinoline, however, the clinical utility of measurements of osteocalcin only to response to therapy is uncertain.

To identify significant prognostic factors in patients undergoing simple hysterectomy in the presence of invasive cervical cancer, the records of 45 patients who had taken such a procedure between 1993 and 1997 were reviewed. Overall relapse-free survival and 5-year survival rates were 91.1 and 92.1%, respectively. Factors found to be significantly related to survival were the retrospectively determined stage(p=0.0000), the presence of residual disease(p=0.0001), and cell type(p=0.0000). By multivariate analysis, factor emerging as significantly detrimental to survival was the cell type. The presence of residual disease was a marginally significant factor(p=0.067). The expectations for survival of patients with residual tumor mass and/or with adenocarcinoma after simple hysterectomy appear to be markedly worse than those with others, so radical reoperation should be considered in those patients.

We report a case of atypical eruption due to chemotherapeutic agent in a 60-year-old man who presented with asymptomatic, erythematous, 0.5cm in diameter, confluent, and elevated papules and plaques confined to the face. The patient was previously diagnosed with small cell carcinoma of the lung with liver metastasis. Two months after the diagnosis, a first course of chemotherapy including etoposide was started. Five days after starting the chemotherapy, the patient developed a facial eruption. Histopathologic examination demonstrated increased epidermal mitotic figures, cells in metaphase arrest, basal cell layer hyperpigmentation, prominent dyskeratosis, and squamous atypia. The most distinctive histologic feature was the presence of starburst cells, which are markedly enlarged pale staining keratinocytes containing small basophilic fragments of nuclear debris haphazardly scattered throughout the cytoplasm in a starburst pattern.

OBJECTIVE: In this study, we examined the reliability and validity of the Korean version of the Prodromal Questionnaire-Brief (PQ-B), a self-report screening instrument for clinical high risk for psychosis (CHR). METHODS: A total of 3,400 middle, high school and college students participated, and 261 subjects with a PQ-B total score ≥3 completed both the PQ-B and the Structured Interview for Prodromal Syndromes (SIPS). Receiver operating characteristic (ROC) curves were used to examine the psychometric properties of the PQ-B. RESULTS: A cut-off of 7 for the PQ-B total score and a cut-off of 22 for the PQ-B distress score showed the best balance of sensitivity (72.2%, 77.8%) and specificity (71.4%, 75.0%). CONCLUSION The Korean version of the PQ-B showed good reliability and validity for predicting prodromal risk symptoms in the community population.

We report a case of pigmented spindle cell nevus which occurred in a 4-year-old male. Several months earlier, his mother noticed a 3x3mm sized annular, hyperpigmented macule on his right thigh. Histopathologic findings showed nests of spindle cells with sharply defined lateral margins in the dermoepidermal junction and cleft around the spindle cell nests with heavy melanin pigmentation.
