This study aimed to analyze the performance and utilization of SDP(Super Absorbent Polymer) applied technology of polymer hygroscopic material. As SDP is a polar material that adsorbs polar molecules such as water molecules and odor molecules, it is 5 times superior in moisture absorption ability compared to the existing inorganic dehumidifying materials and that can be used semi-permanently by repeating moisture absorption and moisture resistance in response to ambient humidity. Also, SDP regenerates at a low temperature and has a very fast moisture absorption rate which can dramatically increase energy efficiency if applying it to systems such as dehumidifiers and dehumidifiers. In addition, it functions as an antibacterial and antifungal due to the characteristics of the electrolyte polymer. Currently, it has been developed as a sheet material and will expand the field of application.

Benign metastasizing leiomyoma (BML) is a rare entity, defined as a muscle tumor in association with one or more smooth muscle tumor of the uterus and without evidence of any extra uterine primary site. The lung is the most common site of involvement,2 and the etiology of BML remains unknown. We experienced a case of BML arising in pelvic and para-aortic lymph nodes and report with a brief review of literature.

Pelvic organ prolapse complicating pregnancy is a rare clinical condition and its incidence is one in 10,000~15,000 deliveries. It is associated with multiparity, low socioeconomic status, inadequate perinatal care, maternal malnutrition, previous abdominal surgery, and weakness of pelvic muscular and connective tissue. It can cause cervical dystocia, which leads to cervical laceration, uterine rupture, maternal and fetal death. We experienced a case, first in Korea, of cervical swelling that developed during labor, prolapsed beyond the vaginal introitus and thus obstructed the birth canal. The patient underwent cesarean section and subsequently received MgSO4 topical therapy and resulted in complete resolution. We report this case with a brief review of literature.

Placenta increta is a kind of placental adhesion which can cause severe postpartum hemorrhage and life-threatening condition. It might necessitate a hysterectomy, but conservative management can be considerable for preserving reproductive potential when possible. A 34-years-old woman in her 41st week of pregnancy had normal full term spontaneous delivery. Retained placenta after removal by placenta forceps resulted in mild bleeding. Placenta increta was clinically diagnosed on computerized tomography. Remnant placenta in situ was nearly disappeared 2 months later after five-time intramuscular injection of 50 mg methotrexate and three-times curettage was done for conservative management.

One of the moot important goals of modem gynecologic oncology is the adequate management of ovarian cancer. This includes early detection and differenciation of recurrence or residual tumor. A promising method is available today with the use of metabolic substrates used by tumor cells that are labeled with positron emitting isotopes and a special instrument capable of detecting the radiations in vivo. Measuring tumor metabolic characteristics appear also to differenciate tumor recurrence or residual tumor from surgical or irradiation changes which is important since this will not be defferentiaited by other modalities such ac CT or MRI. The goal of this study was to determine the potential utility of whole-body PET using the glucose analogue 2-(18F)-fluoro-2-deoxy-D-glucose(F-18-FDG) for the detection of primary, metastatic, and recurrent ovarian cancer. Six patients had imaging studies prior to laparotomy for suspected ovarian cancer. PET(Positron Emission Tomography) scans were done with an ECAT 921(Emission Computed Axial Tomography 921, Siemens/CTI. The result of this study show good correlation between PET and pathological findings The tumor detection rate of CT, MRI, CA-125, PET for ovarian cancer was 50%, 75%, 25%, 100% respectively. In summary, this work indicates that PET may be useful in the management of patients with ovarian cancers by identifying occult foci of metabolically active tumor that do not appear on morphological studies.

Background: Postpartum thyroiditis(PPT) is one of syndromes of thyroid dysfunction that occurs in the first year after parturition. Reported incidence of PPT is 3.9-8.2% of postpartum women in several studies from different countries. The fact that 52-100% of patients with PPT have thyroid autoantibodies, and that lymphocytic infiltration of thyroid gland is the characteristic pathological feature of PPT suggest that PPT is an autoimmune disease. High iodine intake in short term period is known to aggrevate the experimental autoimmune thyroiditis. This study was performed to investigate the incidence and clinical features of PPT in Korean postpartum women who usually ingest excessive amount of idine in immediate postpartum period and to investigate the predictive value of thyroid autoantibodies in the development of PPT in them. Method: Between March 1996 and February 1997, 99 women without previous history of any thyroid disease who delivered babies at Boramae hospital were enrolled. Thyroid function parameters(T3, T4, free T4, TSH), thyroid autoantibodies(anti-microsomal antibody, anti-thyroglobulin antibody) and urinary iodine excretion were measured prospectively before and 1, 3 months after delivery. Dietary iodine intake during postpartum period was evaluated by questionnaire, and clinical parameters were followed up. Results: During 3 months of observation, PPT developed in 8.1%(8/99) of postpartum women. Five cases had typical course having thyrotoxic phase and the other 3 cases had hypothyroid phase without toxic phase. However, only one of those required thyroid hormone replacement therapy in the latter group. There were no differences in age, baseline thyroid function parameters, parity, percent cases with family history of thyroid disease between those developed PPT (n=8) and those did not develop PPT(n=91). Duration of high iodine intake(3.8 +- 0.5 wk. vs. 3.7 +- 0.8 wk., p$gt;0.05), total ingested amount of high iodine diet(77 +- 28 vs. 79 +- 24 bowels of miyokguk, p)0.05), and the urinary iodine excretion(1.9 +- 1.4 mg/g creatinine vs. 3.7 +- 3.7mg/g creatinine, p0.05) at 1 month postpartum were not different between two groups. Of 99 total subjects, anti-microsomal antibody(AMA) was present in 13.1%(13/99) before delivery in their sera. Positive predictive value of the presence of AMA before delivery in predicting the development of PPT was 30.8%. Conclusion: The fact that incidence of PPT in normal Korean postpartum women who usually have high iodine intake in immediate postpartum period is not higher than those of other countries, and that there was no difference in the amount of iodine intake between those developed PPT and those did not suggest that high iodine intake in immediate postpartum period do not influence on the incidence of PPT. The presence of AMA before delivery had low specificity in prediction of development of PPT, so the measurement of AMA seems not to be a useful screening test (J Kor Soc Endocrinol 13:339-350, 1998).
