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.

Journal of the Korean Ophthalmological Society 1998;39(6):1204-1211
Most of the macular hole retinai detachinents are limited to the perimacular area. Therefore, we must look for the peripheral retinal hole when the macular hole retinal detachment extends beyond equator. And the principle of operation should be on the peripheral retinal hole rather than macular hole. Authors studied the clinical feature of macular hole retinal detachment associated with the peripheral retinal hole. Among the 39 macular hole retinal detachment patients, peripheral hole was found in 12 patients (30.7%). Sex distribution was the same and mean age was 55.9 years old. Retinal detachment was not diagnosed for more than I month in 7 cases (58.4%). Nine cases (75.0%) were extensive retinal detachments extending beyond 3 quardrants. Nine cases (75.0%) had one peripheral hole and most of peripheral holes were found on the ternporal side. Associated diseases were cataract (5 cases, 38. 5%) and high myopia (5 cases, 38.5%). In 4 cases (33.3%) hole was found on the opposite side. Among the 12 macular hole retinal detachment patients, 11 operations were performed with the technique of gas injection and scleral buckling which lead to successful attachment in 5 cases (41.7%). Among the 7 cases in which reoperations were needed, 3 cases (42.9%) were recurred in 3 months. In 8 cases (66.7%) there were improvements of post-operative visual acuity.

OBJECTIVE: To determine if birth weight greater than 4000gm can be predicted by ultrasound measurement of abdominal circumference(AC) and if shoulder dystocia in macrosomic infants can be predicted by ultrasound measurement of the difference between the abdominal diameter(AD) and biparietal diameter(BPD). METHODS: A Retrospective study was performed of births occuring from March, 1998 to August, 1999 at department of Obstetrics and Gynecology, College of Medicine, Chung-Ang University. Among neonates of birth weight greater than 4000 gm, 50 cases in that ultrasound examination was done within 2 weeks before delivery were selected for macrosomic group and 50 cases were selected for control group during the same period, among neonate of birth weight from 3100gm to 3900gm. RESULTS: 1) Normal spontaneous vaginal delivery(NSVD) was 41 cases in control group and 30 cases in macrosomic group. Among NSVD, shoulder dystocia was 1 case in 41 cases of control group and was 7 cases in 30 cases of macrosomic group. 2) On ultrasound measurement, 6 cases had AC greater than 35 cm in control group and 45 cases in macrosomic group. Among 30 cases in NSVD was done in macrosomic group, difference between AD and BPD was 2.9 0.271 cm when shoulder dystocia was existed and was 2.1 0.409 cm when shoulder dystocia was not existed. Between the two groups, statistically significant difference was detected. 3) When AC(cutoff value of 35cm) was used for screening of macrosomia, sensitivity for macrosomia was 88.2% and specificity was 89.8% and when AD-BPD difference(cutoff value of 2.6cm) was used for prediction of shoulder dystocia, sensitivity for shoulder dystocia was 66.6% and specificity was 95.2%. CONCLUSIONS: In prenatal ultrasound measurement, AC measurement at third trimester of pregnancy will be a valuable indicator for macrosomia screening. The AD-BPD difference of shoulder dystocia group was greater than uncomplicated group in macrosomia and the AD-BPD difference cutoff value of 2.6cm was significant value statistically.

OBJECTIVE: To estimate the long-term skeletal responses to hormone replacement therapy(HRT) with or without active vitamin D(VD) by using short-term changes of bone markers in postmenopausal women (PMW). METHODS: Biochemical markers of bone formation(osteocalcin,OC) and (&) resorption(deoxypyridinoline, Dpd ) at 3 months & lumbar bone mineral density(BMD) at 1 year were measured in 64 natural PMW taking HRT(n=41) & HRT with calcitriol 0.25 microgram/day(n=23). The correlation of percent changes of bone markers after 3 months of Tx with those in lumbar BMD after 1 year was evaluated. RESULTS: 1. serum-OC & urine-Dpd showed decrease of 20.9% & 30.1% at 3months respectively & BMD increase of 3.8% after 1 year of Tx. 2. Among 58 PMW with decreased u-Dpd change, 49 (84.5%) revealed increase in BMD, while 40 (81.6%) among 49 PMW with decreased serum-OC change showed increased BMD. 3. Bone gainers showed significant decrease in changes of serum-OC(18.1% vs 9.2% p<0.05) & urine-Dpd(32.6% vs 20.4%, p<0.05) compared with those of bone losers. 4. No correlations of change of serum-OC (r=-0.174 p>0.05) & urine-Dpd (r=-0.091 p>0.05) at 3month with BMD changes at 1year were seen in total PMW, but urine-Dpd changes in HRT without active VD group revealed significantly inverse correlation(r=-0.376 p<0.05). CONCLUSION: Short-term changes of bone markers did not precisely predict the long-term changes of BMD in total PMW except urine- Dpd in HRT without active VD.

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.

OBJECTIVE: Proteinuria is a major clinical manifestation as well as hypertension and generalized edema in pregnancy-induced hypertension(PIH) and it should be considered an important marker of perinatal outcome. We studied the impact of proteinuria on maternal and perinatal outcome according to the degree of urine protein in PIH. METHODS: Maternal urine protein and serum albumin levels were studied in 64 cases of PIH who were admitted to Department of Obstetrics and Gynecology, Pil-Dong Hospital, College of Medicine, Chung-Ang University for the period of 10 years from January 1, 1989 to December 31, 1998. RESULTS: Serum albumin level was 2.9+/-0.7g/dL in mild preeclampsia group and 2.7+/-0.7g/dL in severe peeclampsia group and there was a significant difference between them. Birth weight of infant was 3001+/-659g in mild preeclampsia group and 2446+/-878g in severe peeclampsia group, and there was a significant difference between them. 1 minute Apgar score was 8.4+/-2.4 and 7.6+/-3.4, respectively and there was a significant difference between them. 5 minute Apgar score was 9.5+/-1.8 and 8.4+/-2.9, respectively and there was a significant difference between them. There were several maternal complications above 2(+) urine protein and no maternal complications below 1(+) urine protein. Small for gestational age infant was more common above 2(+) urine protein than below 1(+) urine protein and fetal death was more common in 3(+) urine protein. CONCLUSIONS: There was a decreasing trend in gestational weeks at delivery as proteinuria become more severe and also in birth weight, 1 minute Apgar score and 5 minute Apgar score. Maternal and fetal complications were more common as proteinuria become more severe.

8.Determination of Safe Contrast Media Dosage to Estimated Glomerular Filtration Rate Ratios to Avoid Contrast-Induced Nephropathy After Elective Percutaneous Coronary Intervention.
Korean Circulation Journal 2011;41(5):265-271
BACKGROUND AND OBJECTIVES: To avoid the risk of developing contrast-induced nephropathy (CIN), it has been suggested that patients be subjected to a minimal necessary dose of contrast medium (CM-dose). However, often it is not easy to determine such a dose. This study assessed the usefulness of the ratio of CM-dose to estimated glomerular filtration rate (eGFR) in predicting the risks of CIN and sought to determine the safe level of CM-dose/eGFR in patients undergoing non-emergent percutaneous coronary intervention (PCI). SUBJECTS AND METHODS: We enrolled a total of 226 patients and calculated the ratio of CM-dose using grams of iodine (g-I) to eGFR, thus expressing it as g-I/eGFR. Among the CIN patients, those with ne-phropathy requiring dialysis (NRD) were also evaluated. RESULTS: Overall, there were 16 cases (7.1%) of CIN. On univariate and multivariate regression analysis, g-I/eGFR alone was found to be an independent predictor for CIN (hazard ratio=10.73, p<0.001). In an receiver operating characteristic analysis, fair discrimination for CIN was found at a g-I/eGFR level of 1.42 (C statics=0.867), and at this value, the sensitivity and specificity were 81.3% and 80%, respectively. Of patients (n=51) with g-I/eGFR > or =1.42, 23.6% (13/51) and 7.8% (4/51) developed, while those with g-I/eGFR <1.42 (n=171) had a lower incidences of CIN (1.8%, 2/171, p<0.001) and NRD (0%, 0/171, p<0.001). CONCLUSION: It can be concluded that a g-I/eGFR <1.42 is a simple, useful indicator for determining the safe CM-dose based on the pre-PCI eGFR values. Furthermore, g-I/eGFR might have a close relationship with the development of NRD as well as CIN.

Bone graft and guided tissue regeneration have been used for the regeneration of periodontal tissue which is the ultimate goal of periodontal treatment. Recently, it was reported that some kind of growth factors were used for regeneration. Platelet rich plasma was researched that it could increase the density of bone and the rate of bone regeneration. For that, 25 patients which have pocket depth more than 5mm at any of 6 surfaces, of healthy patient without any systemic disease were treated. Biogran? were grafted into 14 infrabony pockets as controls, and Biogran(R) with PRP were inserted into 31 infrabony pockets. And then, follwing evaluations were made at the end of 1, 3 and 6 months. 1.There was no statistical difference between control and experimental group in pocket depth, gingival recession, minimum probing attachment level and maximum probing attachment level at preoperation(p>0.05). 2.Decrease in probing pocket depth were reduced to 3.32mm for experimental group and 2.71mm for control group. The decrease was evident at the end of 1 month, they were 2.97mm and 2.29mm, and it was statistically difference(p<0.05). 3.Gingival recession was increased by 0.55mm in experimental group and 0.50mm in control group, it was evident at the end of 1 month. And it was statistically difference(p<0.05). 4.Minimum probing attachment level was increased by 0.35mm in experimental group and 0.36mm in control group, it was statistically difference(p<0.05). 5.Maximum probing attachment level was decreased by 3.19mm in experimental group and 2.93mm in control group, it was statistically difference(p<0.05). 6.There was no statistical difference between control and experimental group in pocket depth, gingival recession, minimum probing attachment level and maximum probing attachment level(p>0.05). There was statistical difference in decrease of pocket depth between pre-operation and 1 month after post-operation(p<0.05). In conclusion, bone graft using Biogran? and bone graft using Biogran? with platelet rich plasma were both effective in treatment of infrabony pocket, bone graft using Biogran? with platelet rich plasma was more effective in early soft tissue healing.

10.Optimization of Stent Deployment by Intravascular Ultrasound.
The Korean Journal of Internal Medicine 2012;27(1):30-38
Intravascular ultrasound (IVUS) is a useful diagnostic method that provides valuable information in addition to angiography regarding the coronary vessel lumen, dimensions, plaque burden, and characteristics. The major use of IVUS in coronary intervention is to guide interventional strategies and assess optimal stent deployment. Since the introduction of the drug-eluting stent (DES), concerns about restenosis have decreased. However, high-risk lesion subsets are being routinely treated with DESs, and the incidence of suboptimal results after stent deployment, such as stent underexpansion, incomplete stent apposition, edge dissection, geographic miss, and the risk of stent thrombosis, have correspondingly increased. Thus, optimization of stent deployment under IVUS guidance may be clinically important. In this review, we focus on the potential role of IVUS in stent optimization during percutaneous coronary intervention and its clinical benefits.
