Premature rupture of membrane is the most frequent cause of low birth weight infant delivery which increase the maternal and fetal morbidity and perinatal mortality. A retrospective case-control study was performed on 315 mothers who delivered low birth weight infants(< or = 2.5kg) with premature rupture of membrane and as control group 546 mothers who delivered normal birth weight infants(2.9-3.7kg) without premature rupture of membrane were chosen. The results obtained from this study were as follows: 1. The proportion of low birth weight infants due to premature rupture of membrane among all low birth weight infant deliveries was 14.5%, and this is equivalent to 1.1% among all deliveries. 2. The most significant maternal risk factor of low birth weight infant deliveries with premature rupture of membrane was infections on vagina, cervix and uterus during pregnancy. Compared with control, adjusted odds ratio was 7.61(95% confidence interval(CI) 1.88-30.88, p=0.004). Other significant maternal risk factors were the history of induced abortion, spontaneous abortion, and the experience of premature delivery. The risk ratios were 1.82, 2.07, 4.42, respectively. 3. Breech presentation did increase the risk of low birth weight infant delivery with infant delivery with premature rupture of membrane against control(Adjusted odds ratio=2.66, 95% CI 1.35-5.26, p=0.005). 4. Mothers who had not taken antenatal care were having higher risk of low birth weight infant delivery with premature rupture of membrane against control(Adjusted odds ratio=1.73, 95% CI 1.35-5.26, p=0.004). These study results show that maternal factors such as the infection of genital organs during pregnancy, the history of induced abortion and breech presentation are significantly associated with the premature rupture of membrane in the low birth weight deliveries, and that most of these risk factors are controllable ones through proper antenatal cares.

Tuberculous bronchoesophageal fistula is a rare disease. We experienced a case of the tuberculous bronchoesophageal fistula, which was found by endoscopy and surgically confirmed. A sixty seven years old female patient complained of foreign body sensation in the throat and frequent aspiration, especially after liquid meal. Esophagoscopic ex- aminatian showed the orifice of the fistula in the midesophagus at the level of 28 cm from the incisors. Esophagogram showed bronchoesophageal fistula between midesophagus and the right intermediate bronchus. A bronchoscopy visualized fistulous tract with granulation in the right intermediate bronchus. Biopsy specimens obtained from the bronchus revealed the esophageal tissue with granulation and multinucleated giant cells. Fistulectomy with wrapping procedure was performed successfully. Surgical pathologic findings confirmed a small focal granuloma and chronic inflammations, compatible with tuberculosis. There was no evidence of malignancy at the specimens. She was treated with anti-tuberculous agents and became well.

Determmation of the chomosomal constitution of human spermatozoa has been camed out though the human-hamster interspecific in vitro fertilization(IVF) system. In recent years, the introduction of fluorescence in-situ hybridization(FISH) technique has provided an alternative approach to evaluate the cbmmosomal constitution of human spermatozoa. The nuclei of mature spermatozoa are highly condensed with interpmtamine disulphide bridges, therefore the success of FISH on interphase human spermatozoa relies on partial decondensation of the sperm chromatin. In early studies, dithioothreitol(DTT) has been known as an efficient decondensation agent. Since then, several different decondensation methods using D1T have been establisdhed, and in terms of decondensation, we were tried to fix the optimal decondensation protocol using DlT. In our study, the optimal concentration and treatment time were 1-mM and 30 min, respectively. We examined chromosome complements of human sperm to investigate the effect of paternal age on the hequency of nondisjunction in human sperm. We investgated sperm karyotypes ftom two diffaent age groups)28+/-0.5, 46+/-6), A minimum of 1000 spermatozoa for one patient were analyzed. The mean frequencies of YY, XX, XY, 21-disamy spermatozoa ware 0.04%, 0.45%, 0.40%, 0.45% respectively in young age group and 1.06%, 0.62%, 1.06%, 0.76% in old ages. The mean frequency of disomy spermatozoa was higher in old age poup compare with those of young age group.

A pancreatico-pleural fistula (PPF), caused by rupture of a pancreatic pseudocyststectomy or obstruction of the pancreatic duct, is a rare condition. A 48-year-old man with chronic alcoholism was admitted with a massive pleural effusion. Pleural fluid studies revealed elevated amylase and lipase. A PPF complicated by a ruptured pancreatic pseudocyststectomy was diagnosed by computerized tomography scan. Although the symptoms improved with conservative management, (chest tube drainage, NPO, total parenteral nutrition, and a pancreatic secretion inhibitor), a distal pancreatectomy, including a pseudocystectomy and thoracotomy, were performed for an increasing size of the hemorrhagic pancreatic pseudocyststectomy and a recurrent hemorrhagic pleural effusion. There were no post-operative complications and the patient was discharged on post-operative day 27.

PURPOSE: In spite of improved local control and adjuvant therapy in breast cancer, many patients after a modified radical mastectomy suffer from locoregional or systemic failure. The purpose of this study was to assess both the patterns of failure following a mastectomy and the predictive factors affecting the risks of locoregional or systemic failure. METHODS: The study population consisted of 195 patients who developed locoregional or systemic failure from among 1,187 patients treated by using a modified radical mastectomy between July 1989 and October 1998 at the Asan Medical Center's Breast Clinic. The median follow-up time following the mastectomy was 41 months (range; 1-119 months). RESULTS: Isolated locoregional recurrence (LRR) developed in 46 patients (24%), LRR with distant metastasis in 43 (22%), and only distant metastasis in 106 (54%). The sites of LRR were as follows: the chest wall, 52%; the ipsilateral supraclaviclar node, 22%; and the axillary node, 15%; etc. The first sites of distant metastasis were as follows: bone, 46%; lung, 38%; liver, 12%; brain, 6%; and pleura, 6%; etc. Local or systemic failure appeared within the first 3 years following the mastectomy in 75-82% of the patients, and within 5 years in 95-98%. Multivariate analysis showed that increasing initial tumor size, increasing number of involved nodes, negative progesterone receptor, and increasing histologic grade were significant factors for increased risks of LLR or distant metastasis. CONCLUSION: Half of the locoregional recurrences following a mastectomy are isolated. T-stage, nodal status, progesterone receptor, and histo logic grade may help to identify patients at risk for locoregional or systemic failure after a mastectomy.

BACKGROUND: Reversibly dysfunctional myocardium caused by chronic reduction of coronary perfusion was named as hibernating myocardium. The clinical characteristics, however, was not well studied. METHOD: To observed the effects of revascularization on regional wall motion(RWM) abnormalities in patients with chronic ischemic heart disease, letf ventriculogram and dipyridamole stress Tl reinjection scan with reinjection imagine were done in 60 patients with angina or old myocardial infarction before and after PTCA. Subjects were divided into two groups, group A(21 patients, improved RWM after PTCA) and group B(39 patients, no change or aggravated RWM after PTCA). RESULTS: There were no significant differences in age and sex distribution between two group. Single vessel disease was more prevalent in group A (7/21, 33.3%) than in group B(1/39, 2.6%, p<0.05), and old myocardial infarction was more prevalent in group B(24/39, 61.5%) compared to group A(7/21, 33.3%, p<0.05). Reversible perfusion defects on Tl scan were found in 19 patients, 15 of whom(78.9%) showed improved RWM after PTCA. CONCLUSION: Hibernating myocardium was more prevalent in single vessel disease and angina patients. Sensitivity of Tl reinjection scan for detection of viable myocardium was 78.9%.

BACKGROUND: Acute or subacute stent thrombosis, bleeding complications and restenosis remain major clinical concerns in coronary stenting despite high pressure inflation and intravascular ultrasound guidance. A new strategy of local heparin delivery may maintain sustained local concentration and limit systemic complications. To observe the feasibility and efficacy of local heparin delivery in stenting, local heparin deliveries were performed in stented patients. METHOD: Heparin was delivered(5,000 Units, 1.0ml/min over 10 min) using the Dispatch Catheter, after predilation of target lesons in 10 patients(4 unstable angina, 6 acute myocardial infarction, mean age 52+/-7 yr) in the left anterior descending artery without systemic heparin loading. After local heparin delivery. Palmaz-Schatz stents were placed using standard methods. APTT and CK were checked at 1hr, 3hrs and 24 hrs after local heparin delivery and stenting. Follow-up coronary angiograms were done at 48 hrs and 6 months after stenting. RESULTS: All patients had no ischemic symptoms or ECG changes during and after local heparin delivery. All APTT and CK values were unchanged at 3 hrs and 24 hrs after local heparin delivery and stenting. Follow-up quantitative coronary angiograms at 48 hrs and 6 months showed all stents patent, with TIMI III distal flow, and without intra-stent thrombus(%diameter stenosis : 79.4+/-4.2% before predilation, 32.9+/-7.7% after predilation, 32.4+/-13.1% after local delivery, 14.2+/-2.3% immediately after stenting, 13.9+/-2.5% at 48 hrs and 21.7+/-8.8% at 6 months after stenting). CONCLUSION: Intracoronary stenting may be performed safely and effectively without systemic heparin therapy by using local heparin prior to stent implantation. Long-term stent patency and lack of coronary events appear favorable.
