BACKGROUND: Factors leading to coronary remodeling and relationship between remodeling patterns and clinical presentation remain unclear. METHODS: Seventy-five culprit lesions of 75 patients with acute coronary syndrome(ACS)(n=9) and stable angina(SA)(n=6)(60 men and 15 women; mean age 56+/-10 years) were studied by intravascular ultrasound. Remodeling index(RI) was calculated as culprit lesion vessel area(VA)/proximal reference VA.

BACKGROUND: Recent data suggest that the colonization rate of group B streptococci(GBS) in pregnant women and the incidence of neonatal infections by GBS is increasing trend in Korea, but the antimicrobial susceptibilities and serotypes in pregnant women have not been reported in Korea. So, we studied to define the antimicrobial susceptibility patterns and frequency of serotypes of GBS in pregnant women. METHODS: The susceptibility and serotyping of 60 GBS isolates from 27 pregnant women and four isolates from their two neonates were tested by an agar dilution method and agglutination test, respectively. The typing sera used in this study were Ia, Ib, II, III, IV, and V. RESULTS: Minimal inhibitory concentration range of 60 GBS from pregnant women were penicillin G 0.015-0.12 microgram/ml, vancomycin 0.5-2 microgram/ml, clindamycin 0.015-4.0 microgram/ml, chloramphenicol 2-4 microgram/ml, erythromycin 0.015-2 microgram/ml, tetracycline 0.5-256 microgram/ml, cephalothin 0.12-0.25 microgram/ml, ceftriaxone 0.03-0.12 microgram/ml, respectively. The resistance rate of GBS were 6.7% to clindamycin, 0% to erythromycin, and 98.3% to tetracycline. Most of GBS serotypes from pregnant women in decreasing order were Ib(48.3%), Ia(24.1%), III(20.7%). CONCLUSION: All GBS strains isolated from pregnant women are highly susceptible to commonly used antimicrobial agents with the exception of tetracycline. The low prevalence of severe neonatal GBS infections in Korea is not due to the absence of serotype III, but probably due to a low genital carriage rate of GBS by pregnant women.

PURPOSE: To evaluate the merits of this technique and to provide a standard for comparison with futuretreatment alternatives. MATERIALS AND METHODS: We retrospectively reviewed the records of 52 patients withdirect CCF treated at the Yonsei Medical Center between 1983 and 1997 by transarterial or transvenous embolizationusing detachable balloon(s) and/or coils. RESULTS: Among the 52 cases, 51 were traumatic in origin, while onlyone was the result of a ruptured aneurysm. The three most common presentations were chemosis, bruit, andpulsatile proptosis. Forty-five patients were successfully treated with detachable balloon(s) and/or coils andinternal carotid blood flow was preserved in 35. When coils were used (1993-7), the ICA preservation rate washigher than when they were not used (1983-92). To confirm statistical significance, however, more studies areneeded. Four patients who initially presented with incomplete occlusion showed spontaneous occlusion on follow upangiography. In two patients, surgical ligation was performed because embolization failed and there was incompleteocclusion of the fistula. We experienced complications such as transient 3rd and 6th cranial nerve palsy,migration of deflated balloons and coils to the lung, and loss of vision. CONCLUSION: Transarterial andtransvenous embolization with detachable balloon(s) and/or coils provides a high rate of fistula obliteration withlow morbidity. In particular, the use of coils led to an increased rate of ICA preservation, thus and isconsidered as a good treatment modality for CCF obliteration.

Nonimmune hydrops fetalis is becoming a predominant form of fetal hydrops due to the declining incidence of immune hydrops fetalis triggered by Rh isoimmunization. Infantile polycystic kidney appeared to be related to hydrops fetalis whether it is causal or merely coincidental and may represent another entry to differential diagnoses. Infantile polycystic kidney was diagnosed by an elevated maternal serum alpha-fetoprotein (AFP) value coupled with an ultrasonographic abnormality scanned as a multicystic mass with ascites in the fetal abdomen antenatally. This study presents a case of infantile polycystic kidney that resulted in a stillborn baby with hydrops fetalis and extensive placental calcification; it was the first case in Korea in which nonimmune hydrops fetalis was associated with infantile polycystic kidney in consecutive siblings by autosomal recessive inheritance in one family. In addition, this paper comprehensively reviews the incidence, etiology, prenatal diagnosis and proper management of nonimmune hydrops fetalis.

BACKGROUND AND OBJECTIVES: It is well known that anti-platlet agents decrease the rate of subacute thrombosis after intracoronary stenting significantly. The aim of this study is to assess the antithrombotic effect and safety of 2-month combined regimen of cilostazol and aspirin on intracoronary stenting. METHODS: The study population consisted of 78 lesions of 57 patients (age: 58.1+/-10.3, male 47, female 10) with ischemic heart disease who were underwent successful intracoronary stenting. They were received cilostazol(200mg/day) and aspirin(100mg/day) two days before intracoronary stenting and continued for 8 weeks, and then aspirin was medicated continuously during the study. The laboratory and clinical findings were evaluated before cilostazol administration, 4 weeks, 8 weeks and 6 months after intervention. The excercise treadmill test was done at 6 months after intervention. RESULTS: Subacute thrombosis occurred in 2 patients(3.5%). Target lesion revascularization(TLR) was done in 4 patients(7.3%). Clinical restenosis (symptomatic or positive stress test, subacute thrombosis and TLR) occurred in 15 patients(26.3%). There was no granulocytopenia, or severe liver dysfunction. HDL-cholesterol was increased significantly at 2 months(36.6+/-7.4 mg/dl versus 41.6+/-9.3 mg/dl. p<0.01) and 6 months(36.6+/-7.4 mg/dl versus 42.4+/-10.6 mg/dl. p<0.01) follow up. CONCLUSION: Two-month combined regimen of cilostazol and aspirin was effective and safe after intracoronary stenting. Subacute thrombosis and clinical restenosis rate were comparable with pervious reports. Further large randomized trials are needed for the evaluation of favorable effect of cilostazol on lipid metabolism.
