OBJECTIVE: To evaluate the pregnancy outcome, designate the predicting factor of neonatal thrombocytopenia, and reevaluate the treatment scheme of idiopathic thrombocytopenic purpura (ITP) in pregnancy. METHODS: Medical records of 83 patients(98 deliveries) who were diagnosed as having ITP and delivered at the Department of Obstetrics and Gynecology, Yonsei University College of Medicine from January 1990 to May 1999 were reviewed. For statistical analysis Chi-square test and Fisher's exact test were used. RESULTS: Among various maternal characteristics, inability to raise platelet counts more than 100,000/mm3 by any means of treatment, categorized as ""poor response to treatment"", could be designated as the predicting factor of neonatal thrombocytopenia (p<0.05). Pregnant women treated with prednisolone had significantly greater chance of having preterm delivery (p<0.001). The occurrence of postpartum anemia requiring transfusion was higher in the group undertaking cesarean section (p<0.05). Although a control group was missing, the pregnancy outcome was poor in the category of pregnancy induced hypertension(PIH) and preterm labor being 17.3% and 33.7%, respectively. CONCLUSION: The ITP patient should be carefully monitored during the antenatal care visits because of the increased incidence in adverse pregnancy outcome such as PIH and preterm labor. Neonatal thrombocytopenia could be predicted in the presence of inability to raise platelet counts to more than 100,000/mm3 by any means of treatment. Cesarean section should not be performed routinely under the indication of ITP due to the accompanynig morbidity and low incidence of bleeding sequalae in the neonate. The accompanying complications of prednisolone treatment raises questions and warnings about its usage, therefore a prospective study is warranted to evaluate the effect and complications of prednisolone treatment.

There are a number of published reports aimed at clarifying the effect of hormonal contracept -ives upon the quantity and quality of breast milk during postpartum and lactation periods. As to the volume of milk produced by breast feeding mothers, many authors seem to have agreed on a decrease as an established pattern in the periods following regular administration of oral contraceptives containing estrogen in varying dosage. The quality of milk following administration of hormonal contraceptives, however, remsins a controversial issue. Korea's experience in oral contraceptive is rather a brief one, but use of Eugynon has been widespread and frequent since this hormonal contraceptive was introduced into the national program in 1967. The authors have reviewed the potential significance of data concerning regular use of an oral contraceptive as affecting lactation, and have sought to clarify the interrelationship between the administration of Eugynon and quantity and quality of breast milk from mothers contracepting. with Eugynon in different periods following confinement. A total of 85 women, who were at different periods following deliveries, have been divided into, two groups, one comprising 28 women regularly taking oral pills and the other (57 women) not resorting to hormonal contraceptives if they were contracepting at all. 1. Milk Volume. In view of the possible influence of suckling on the amount of milk produced, efforts were made in this study to standardize the technique by extracting breastmilk by applying manual pressures on one side of the maw-nae, While the nipple on the other side was being sucked by the mother's own baby. The effetct of an exogenic ovarian hormone on the quantity as well as quality of breastmilk is generally understood to be inapparent until the drug is administered to women whose milk secreting function has been normalized. ") In the present study, it was observed that the decrease in the ammount of milk obtained from mothers in the periods following the 4th cycle of oral contraceptives or thereafter has turned out to be statistically insignificant. This result conforms i.u the findings by Tubari and others. It is assumed that it takes at lest 2 to 3 cycles of use before mammary glands are functionally adjusted to the use of exogenic hormonal contraceptives. 2. Specific Gravity and Composition of Milk There was no noticeable change in the protein and chloride content following continuous administration of ore.l contraceptives, while meaningful changes were observed in fat (increase) and calcium (decrease up to the 5th cycle use) contents. Also, there was a rather significant decrease in the specific gravity in the period following administration of the first cycle of the oral contraceptive. The findings from the present study partially conforms the results published by Ramadan and others, who reported that little change was noticed in the contents of total solids. ash, chlorides and lactose in the breast milk of women who had taken 4 cycles of ovosiston, although in our study lactose was not measured. Ramaden, however, reported that fat content did increase in the same milk, as in our study. A definitive conclusion, however, could not be made unless measures are taken to rule out the physiological changes of the maternal body affecting the composition of milks.

The blue rubber bleb nevus syndrome(CRBNS) is a rare disorder characterized by distinctive vascular malformations of the skin and gastrointestinal tract. The syndrome is associated commonly with iron deficiency anemia due to gastrointestinal bleeding. Most cases are sporadic, although a few have been reported with autosomal dominant inheritance. We report a case with clinical characteristics of the blue rubber bleb nevus syndrome. The patient had typical skin manifestations of the BRBNS and chronic iron deficiency anemia. However, we could not find any gastrointestinal vascular malformations radiologically.

From May, 1978 through Oct., 1979 the effect of Coenzyme Q10 was evaluated on 10 patients with chronic heart failure. The subjects selected for this study consisted of 7 patients with cardiomyopathy and 3 patients with valvular heart disease admitted to Severance Hospital, Yonsei University College of Medicine, All these patients had symptoms and signs of congestive heart failure which was stable for at least one month before starting Coenzyme Q10. Coenzyme Q10 was administered 30mg daily for eight weeks, one hour before meal and in combination with digitalis and/or diuretics. The drug effects were determined by measuring the cardio-thoracic ratio by chest X-ray, the sum of 'S' wave in V1 and 'R' wave in V5 in electrocardiogram, and PEP/LVET (pre-ejection period/left ventricular ejection time) by simultaneous tracings of carotid pulse and phonocardiogram every two weeks during medication. The cardio-thoracic ratio was improved in 4 of 10 cases, the sum of RV+SV5 was decreased in all 5 cases who showed voltages above 40mm before medication, and PEP/LVET ratio was decresed in 4 of 10 cases. The difference of average values before and after medication were not statistically significant(p<0.05) in all 3 parameters when examined by t-test. During treatment, there was improvement, if any, from two weeks after medication and no significant side effects were noted throughout the study period.

The investigation of systolic time intervals and hemodynamics was performed in 42 patients with liver cirrhosis by noninvascive methods. The patients were divided into four groups according to the presence or absence of anemia and/or ascites: i.e. group I; cirrhosis without anemia and ascites, group II; cirrhosis with ascites only, group III; cirrhosis with anemia only, and group IV; cirrhosis with ascites and anemia. In the resting state of the patients, the systolic time intervals and hemodynamic data were measured by the high speed simultaneous recordings of electrocardiogram, phonocardiogram, carotid and femoral arterial pulse tracings, and compared with those obtained from 155 normal adult subjects. 1. The pulse were increased considerably in group IV, and diastolic blood pressure was elevated in group II with significance. 2. The stroke volume and cardiac output were increased significantly in group III. 3. The peripheral resistance was reduced particularly in group III, and the volume elasticit coefficient was decreased in group IV. 4. The QS1 interval was prolonged significantly in group II and IV, but QS1 interval corrected by multiple regression equation proposed by our laboratory (illustrated in the text) did not show significant difference compared with that of normal subjects. 5. The left ventricular ejection time(LVET) and total electromechanical systole(QS 2) appeared to be shortened in group II and IV, but the corrected LVET and QS 2 were not different significantly from those of the normal subjects

In male reproducible health, fertility and IVF (in-vitro fertilization), semen analysis has been most important. Semen analysis can be divided into concentration, motional and morphological analysis of sperm. The existing method which was developed earlier to analyze semen concentrated on the sperm motility analysis. To provide more useful and precise solutions for clinical problems such as infertility, semen analysis must include sperm morphological analysis. But the traditional tools for semen analysis are subjective, imprecise, inaccurate, difficult to standardize, and difficult to reproduce. Therefore, with the help of development of microcomputers and image processing techniques, we developed a new sperm morphology analyzer to overcome these problems. In this study the agreement on percent normal morphology was studied between different observers and a computerized sperm morphology analyzer on a slide-by-slide basis using strict criteria. Slides from 30 different patients from the SNUH andrology laboratory were selected randomly. Microscopic fields and sperm cells were chosen randomly and percent normal morphology was recorded. The ability of sperm morphology analyzer to repeat the same reading for normal and abnormal cells was studied. The results showed that there was no significant bias between two experienced observers. The limits of agreement were 4.1%~-3.8%. The Pearson correlation coefficient between readers was 0.79. Between the manual and sperm morphology analyzer, the same findings were reported. In this experiments the slides were stained by two different methods, PAP and Diff-Quik staining methods. The limits of agreement were 7.2%~-5.7% and 6.0%~-6.3%, respectively. The Pearson correlation coefficients ware 0.76 and 0.91, respectively. The limits of agreement was tighter below 20% normal forms. In the experiments of repeatability, 52 cells stained by PAP and Diff-Quik staining methods were analyzed three times in succession. Estimating pairwise agreement, the kappa statistic for the pairs were 0.76, 0.81, 0.86, and 0.75, 0.88, 0.88 respectively. In this study it was shown that there was good agreement between manual and computerized assessment of normal and abnormal cells. The repeatability and agreement per slide of computerized sperm morphology analyzer was excellent. The computer's ability to classify normal morphology per slide is promising. Based on results obtained, this system can be of clinical value both in andrology laboratories and IVF units.
