We observed clinical features of 18 bronchopulmonary dysplasia (BPD) patients who were admitted to the neonatal intensive care unit in the Severance Hospital of Yonsel University College of Medicine from January 1. 1987 to June 30. 1991. Eight patients in whom ventilator settings were unchanged for more than 5 days because of lack of improvement in pulmonary function. The effects of dexamethasone in ventilator-dependent were included in the short-term dexamethasone therapy. 1) Eighteen BPD patients consisted of 15 premature infants (83%), 1 full-term infant, and 2 post-term infants, The mean gestational age of the patients were 30 weeks and the mean birth weight was 1,420gm. And there were 13 male and 5 female infants. 2) The underlying conditions which necessitated ventilatory support support were hyaline membrane disease in 13 patients (72%), apnea in 2 (11%), and meconium aspiration syndrome in 3. There patients with meconium aspiration syndrome were either full-term or post-term infants, of whom 2 had neonatal persistent pulmonary hypertension. 3) The mean age at the start of ventilator care was 8 hours and the mean PIP was 32 cm H2O. The mean duration of ventilator care of oxygen therapy and of high O2 requirement (FiO2>0.8) were 39 days, 75 days and 20 days, respectively. 4) Patent ductus arteriosus developed in 8 patients during mechanical ventilation, but they were all closed with the use of mefenamic acid, There were also 4 cases of pneumothorax, 2 cases of pulmonary parenchymal emphysema, and 1 case each of pneumomediastinum and pneumoperitoneum. 5) The mean gestational age of the dexamethasone-treated group was 30 weeks and the mean birth weight was 1,320gm, The mean age at which dexamethasone therapy was started was 39 days after birth, and in only 3.3 days 6 patients were successfully weaned from ventilator, In 5 cases the first trial of dexamethasone therapy was enough but the rest needed the 2nd trial for ventilator weaning. 6) In 6 BPD patient who were weaned from the ventilator after dexamethasone therapy, there were significant decreases in MAP (11.1 vs 8.0 cmH2O), and FiO2 (0.73 vs 0.61), but a significant increase in the urine output (2.56 vs 3.7ml/kg/hr) for the pretreatment (5 days prior to therapy) versus posttreatment period (first day of therapy). 7) The complications of dexamethasone treatment were transient hypertension and hyperglycemia in 3 patients, and systemic candidiasis and gastrointestinal bleeding in 2 patients who failed to be weaned after dexamethasone therapy. Our results suggest that the short-term dexamethasone therapy in bronchopulmonary dysplasia patients who are dependent on mechanical ventilation enables weaning in a short period of time. The inspiratory oxygen concentration and the mean airway pressure may be decreased and the urine output may be increased from the first day of medication, improves pulmonary function and decreases pulmonary interstitial edema.

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.

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.

Autogenous costal cartilage graft has been commonly used for reconstruction of auricular deformity. However, the risk of complication and discomfort at the donor site, as well as distortion of the graft due to morphological change in the cartilage have been serious drawbacks to this procedure. Previous studies examining the chondrogenic potential of perichondrium have suggested that perichondrium may be used as graft for cartilage reconstruction. When a perichondrial flap or a free perichondrium was used as graft, new cartilage formed appositional to the grafted perichondrium. However, the neocartilage was often irregular in shape and varied considerably in quantity. In this study, the feasibility of controlling the shape and the mass of neocartilage was investigated using coral, a porous biomaterial, as a template. A coral a template was wrapped with perichondrial flap from the ears of New Zealand white rabbits and placed into a subcutaneous pocket in the rabbits and placed into a subcutaneous pocket in the rabbit's back by incision. A total of 12 animals were used. Formation of new cartilage was later evaluated by gross and histological examination of the perichondrial flap and the coral template. New cartilage was formed in 11 animals. Immature chondrocytes were visible by 3 weeks after the surgery, and by 8 weeks the immature chondrocytes had formed a cartilage. New cartilage was formed only on the surface of the coral template. These results indicated that the shape and the mass of new cartilage may be controlled by using coral template. Therefore, the desired shape of cartilage may be achieved using a coral template of corresponding shape, and this may help in correcting subtle auricular contour defect and in correcting other structural defects that also require new cartilage formation.
