Histologic study of bone-forming capacity on polydeoxyribonucleotide combined with demineralized dentin matrix / 대한악안면성형재건외과학회지

BACKGROUND: This study examined the osteoinductive activity of demineralized dentin matrix (DDM) from human and polydeoxyribonucleotide (PDRN) for nude mice. METHODS: Twenty healthy nude mice, weighing about 15~20 g, were used for the study. DDM from human and PDRN were prepared and implanted subcutaneously into the dorsal portion of the nude mice. The nude mice were sacrificed at 1, 2, and 4 weeks after grafting and evaluated histologically by hematoxylin-eosin and Masson's trichrome staining. The specimens were also evaluated via a histomorphometric study. RESULTS: The DDM and PDRN induced new bone, osteoblasts, and fibroblasts in soft tissues. The histological findings showed bone-forming cells like osteoblasts and fibroblasts at 1, 2, and 4 weeks. New bone formation was observed in the histomorphometric study. In particular, the ratio of new bone formation was the highest at 2 weeks compared with the first week and fourth week. CONCLUSIONS: In this study, we showed that the PDRN used in this experimental model was able to induce bone regeneration when combined to the DDM.

The Influence of Labor and Cesarean Section in Uroflowmetry / 대한산부인과학회잡지

OBJECTIVE: The purpose of this study is to evaluate the uroflow parameters of the pregnant women before delivery and immediate postpartum period. METHODS: Forty four patients delivered by spontaneous vaginal delivery (NVD group) and 46 patients by Cesarean section (C/SEC group) and 28 non-pregnant young women (Control group) were included in this study. Uroflow were checked 1 day before and 2 days after delivery by Jupiter 8000 (FM Wiest(R)) uroflowmetry. Mean value of the uroflow parameters in each group was compared using ANOVA t-test. For continuous data, linear associations with each of the uroflow parameters were assessed using a Pearson correlation coefficient. RESULTS: Maximal (18.48+/-5.21 mL/sec) and mean flow rate (9.45+/-3.73 mL/sec) of pregnant women were lower than control group (22.75+/-5.14 mL/sec), and were not changed after delivery (18.79+/-6.03 mL/ sec). Total flow time of pregnant woman (14.06+/-6.09 sec) was longer than control group (8.05+/-5.32 sec) before delivery, and increased after delivery especially after cesarean delivery. Time to peak flow of pregnant women (8.44+/-9.48 sec) was shorter than control group (16.33+/-6.11 sec) before delivery, and was similar to control group after delivery. Total voided volume (121.39+/-50.17 mL) was less than control group before delivery, and was increased after delivery (246.77+/-127.42 mL). Total voided volume after delivery was not different with control group statistically. CONCLUSION: There was no statistically differences before and after delivery in maximal flow rate, but was lower than non-pregnant women. Total flow time was much prolonged after delivery, especially after cesarean delivery. Time to peak flow and voided volume were restored to levels of non-pregnant women after delivery.

Two Cases of Myxoid Change in Decidualized Cutaneous Endometriosis in the Abdominal Scar Following Cesarean Section and immunohistochemical study / 대한산부인과학회잡지

Decidualized cutaneous endometriosis infrequently arises in the abscence of pelvic disease. It is described in which the histologic features included cytologic atypia, circumscription of endometrial epithelial cells with glandular or cystically dilated space, mononuclear cells within and around the endometrial nodules, and accompanied myxoid change. This histologic pseudomalignancy is not common and be misinterpreted as metastatic carcinoma or malignant tumors arising from soft tissue due to location of nodule and histologic feature. We have experienced two cases of myxoid change in decidualized cutaneous endometriosis in the abdominal scar following Cesarean section, which is presented with a brief review of the literature.

Malignant Struma Ovarii: two cases report and literature review / 대한산부인과학회잡지

Struma ovarii consists of thyroid tissue which is derived from germ cells in a mature teratoma. Five percent of struma ovarii are malignant, and of these only five percent metastasize. The rarity of this disease has resulted in difficulty in agreeing on treatment regimens and in limited imaging and monitoring difficulties encountered in their management. We have experienced two cases of malignant struma ovarii with brief review of the literature.

Hepatocellular Carcinoma Metastatic to the Ovary: one case report and review literature / 대한산부인과학회잡지

Metastatic hepatocellular carcinoma of the ovary is an extremely rare ovarian tumors and may cause a diagnostic problem. This tumor was first described by Ooartman and Elliot in 1983. The differential diagnosis in cases of hepatocellular carcinoma metastatic to the ovary is with primary and metastatic hepatoid tumors of the ovary and diverse other tumors of the ovary composed of oxyphil cells, which may be primary or metastatic. We have experienced one case of metastatic hepatocellular carcinoma of the ovary with brief review of the literature.

The Clinical Usefulness of Cervicovaginal Fetal Fibronectin as a Prediction of the Time of Induction / 대한산부인과학회잡지

OBJECTIVES: Fibronectin is a high-molecular-weight glycoprotein found in the plasma and extracellular matrix. The presence of fetal fibronectin in cervicovaginal secretion of pregnant women during the second and the third trimester has been suggested as a means of identifying women in preterm labor who be delivered prematurely. Therefore, our purpose was to determine the clinical efficacy of the presence of fetal fibronectin in cervicovaginal secretion of patient in full term as biochemical predictor of Time of Induction. METHODS: Fetal fibronectin was obtained at external os and posterior vaginal fornix in 30 women in full term who had no uterine contraction with intact membrane. The cervix was assessed by digital vaginal examination and scored with a modified Bishop score. RESULTS: There was a good correlation in delivery time after induction between the fetal fibronectin and the modified Bishop score (r=0.695,P<0.005) CONCLUSION: The presence of fetal fibronectin is better than Bishop score that is dependent on clinical experience as biochemical predictor of Time of Induction.

Antenatal Screening for Gestational Diabetes by 50-g, 1-hour Glucose Screening Test / 대한산부인과학회잡지

OBJECTIVE: Gestational diabetes mellitus is defined as carbohydrate intolerance of variable severity first diagnosed during pregnancy. It is associated with adverse outcomes of pregnancy including obstetrical complications such as increased rate of cesarean sections, preeclampsia, and birth trauma, and perinatal morbidities, such as macrosomia, hypoglycemia, hypocalcemia, and hyperbilirubinemia. Therefore, screening for gestational diabetes mellitus and early diagnosis of this condition allows intervention to be carried out, thereby, the reduction of the untoward effects mentioned above can be minimized. METHODS: Screening for abnormal glucose metabolism was carried out in 489 pregnant women. A 50-g oral glucose load without regard to time of day or last meal, and a 1-hour plasma glucose determination with a threshold of 140mg/dl were used as a glucose screening test(GST). Patients with an abnormal GST underwent an oral glucose tolerance test(GTT). RESULTS: The overall incidence of gestational diabetes was 2.7%. The occurrence of this disorder was significantly related to the age of pregnant women, parity, or the presence of risk factors for gestational diabetes and obesity(Body Mass Index> or =26kg/m2). CONCLUSION: This study suggests that Korean pregnant women should be screened for gestational diabetes.

Decision-making process and satisfaction of pregnant women for delivery method / 예방의학회지

This study was conducted to assess the attitude of pregnant women toward delivery method, understanding of the reason for determining her own delivery method, participation in decision-making process and satisfaction with delivery method after labor. Study subjects were 693 pregnant women who had visited obstetric clinic for prenatal care in the last month of pregnancy in one general hospital and one obstetrics-gynecology specialty hospital in Taegu city from February 1 to March 31 in 1998. A questionnaire was administered before and after labor and a telephone interview was done one month after labor. Proportion of women who had health education and/or counselling about delivery method during prenatal care was 24.0% and this proportion was higher for women who had previous c-section(35.5%) than others. Women thought vaginal delivery is better than c-section for both maternal and baby's health regardless of previous delivery method. About 90% of primipara and multiparous women who had previous vaginal delivery wanted vaginal delivery for the index birth, while 85.6% of multiparous women who had previous c-section wanted repeat c-section. Reasons for choosing c-section in pregnant women who preferred vaginal delivery before labor were recommendation of doctors(81.9%), recommendation of husband(0.8%), agreement between doctor and pregnant woman(4.7%), and mother's demand(12.6%). Reasons for choosing vaginal delivery were mother's demand(30.6%) and no indication for c-section(67.2%). Reasons for choosing c-section in pregnant women who preferred c-section before labor were recommendation of doctors(76.2%), mother's demand(20.0%), recommendation of husband(1.3%), and agreement between doctor and pregnant woman(2.5%). Of the pregnant women who had c-section, by doctor's recommendation, the proportion of women who had heard detailed explanation about reason for c-section by doctor was 55.1%. Mother's statement about the reason for c-section was consistent with the medical record in 75.9%. However, over 5% points disparities were shown between mother's statement and medical record in cases of the repeat c-section and mother's demand. In primipara and multiparous women who had previous vaginal delivery, the delivery method for index birth had statistically significant association with the preference of delivery method before labor(p<0.05). All of the women who had previous c-section had delivered the index baby by c-section. Among mothers who had delivered the index baby vaginally, 84.9% of them were satisfied with their delivery method immediately after labor and 85.1% at 1 month after labor. However, mothers who had c-section stated that they are satisfied with c-section in 44.6% immediately after labor and 42.0% at 1 month after labor. Preferred delivery method for the next birth had statistically significant association with delivery method for the index birth both immediately after labor and in 1 month after labor. The proportion of mothers who prefer vaginal delivery for the next birth increased with the degree of satisfaction with the vaginal delivery for the index birth but the proportion of mothers who prefer c-section for the next birth was high and they did not change significantly with the degree of satisfaction with the c-section for the index birth. These results suggest that the current high technology-based, physician-centered prenatal and partritional cares need to be reoriented to the basic preventive and promotive technology-based, and mother-fetus-centered care. It is also suggested that active involvement of pregnant woman in decision-making process for the delivery method will increase the rate of vaginal birth after c-section and decrease c-section rate and improve the degree of maternal satisfaction after delivery.

Perineal Endometriosis

Endometriosis is an enigmatic disease of menstruating females affecting the reproductive life. We report herein a case of perineal endometriosis in a 33-year-old woman. The patient presented two rounded, thickened plaques bilaterally on the perineum for about four year. The plaque on the right side was located mainly at the episiotomy scar. Histologic examination showed confirmative feature of glandular structures embedded in the cellular stroma and predecidual changes of late secretory phase of endometrium. Radical operation of total hysterectomy with bilateral oophorectomy and partial excision of perineal lesions were performed. There was complete resolution with no relapse by the 6-month follow-up. This is of a very rare occurrence and three cases have been reported in the Korean literatures up to date.
