A study of the factors associated with the pattern of gestational weight gain / 대한산부인과학회지

OBJECTIVE: To examine the pattern of gestational weight gain using maternal characteristics and pregnancy outcomes. METHODS: We used maternal weight data from 1,825 women who had noncomplicated pregnancy between Jan. 2002 and Aug. 2009. The rate of maternal weight gain in each trimester, the associations between gestational weight gain per trimester and maternal characteristics and pregnancy outcomes, and the relationship between maternal characteristics and trimester weight gain were analyzed. RESULTS: The average rate of weight gain (kg/week) was lowest during the first trimester (0.06+/-0.30), peaked during the second trimester (0.52+/-0.23), and slowed slightly in the third trimester (0.47+/-0.23). With the exception of infant sex, all six maternal characteristics and pregnancy outcomes included in the multivariate analyses (parity, maternal age, height, BMI, preeclampsia, gestational DM) were associated significantly with maternal weight gain in at least one trimester. The important maternal predictors of weight gain per trimester were prepregnancy BMI, height and age in the first trimester; prepregnacy BMI, parity and height in the second; and height, age and parity in the third. CONCLUSION: The pattern of gestational weight gain is associated with a number of maternal characteristics and pregnancy outcomes, and these relationships vary according to which trimester is being examined.

A Study of the Pregnancy Weight Gains of Noncomplicated Primiparas and Multiparas / 대한주산의학회잡지

OBJECTIVE: To establish the biweekly standard values of pregnancy weight gains for primiparas and multiparas, and to investigate the influence of prepregnancy body mass index on biweekly weight gain during pregnancy. METHODS: We analyzed the biweekly weight gain data from 536 primiparas and 114 multiparas who had noncomplicated singleton term pregnancy. Data was categorized according to parity and body mass index (BMI). RESULTS: Biweekly weight gain was significantly different among prepregnancy BMI groups from the 15th week but was not different between primiparas and multiparas. CONCLUSION: To prevent a lot of complications which may be associated with abnormal weight gain during pregnancy, more careful prenatal care according to the prepregnancy BMI groups is needed. To establish the Korean standard value for antenatal weight gain, a nationwide multicenter study is needed.

A study of the biweekly weight gains of noncomplicated pregnancies / 대한산부인과학회지

OBJECTIVE: To establish the standard values for proper antenatal weight gain, biweekly mean weight gains, standard deviations were calculated from the 5th to the 42nd gestational week and their percentiles were determined. And the influence of prepregnancy body mass index and/or parity on biweekly weight gain was investigated. METHODS: We analyzed the biweekly weight gain data from 910 women who had noncomplicated singleton term pregnancy. Data was categorized in three groups according to body mass index (BMI). RESULTS: The biweekly weight gain table has been determined and 'Sigmoid(S) shaped' weight gain curves were presented. Primipara and multipara have significantly less weight gain than nullipara beyond the 25th weeks. Biweekly weight gain was significantly different among prepregnancy BMI groups from the 13th week. CONCLUSION: More careful prenatal care according to the biweekly weight gain-gestational week tables is needed to prevent a lot of complications which may be associated with abnormal weight gain during pregnancy. To establish Korean standard value for antenatal weight gain, a nationwide multicenter study is needed.

A study of the monthly weight gains of noncomplicated pregnancies among 20s, early and late 30s / 대한산부인과학회지

OBJECTIVE: To calculate monthly weight gains during pregnancy among 20s, early and late 30s, and to investigate the influence of age groups on monthly weight gains. METHODS: We analyzed the monthly weight gain data from 892 women who had visited before 20 weeks of gestation and had healthy singleton term pregnancy. Data was categorized in three groups according to age (20s, early and late 30s). RESULTS: The monthly weight gain tables among 20s, early and late 30s have been determined. Monthly weight gain was not significantly different among three age groups. CONCLUSION: Although statistically insignificant among three age groups, more cautious prenatal care according to the monthly weight gain-gestational month tables for each age group is needed to prevent complications which may be associated with abnormal weight gain during pregnancy.

A Case of Spontaneous Uterine Rupture in 17 Weeks of Pregnancy / 대한산부인과학회지

Placenta percreta occurs when chorionic villi penetrate through the myometrium up to the serosa. The incidence of placenta percreta is extremely rare, but it is accompanied by serious complications of pregnancy and their prediction is very difficult. Since spontaneous uterine rupture during the second trimester is an obstetric emergency, it is critical that the proper management should be taken promptly in order to decrease the maternal morbidity and mortality. We present a case of spontaneous uterine rupture in 17 weeks of pregnancy.

A Case of Imperforate Hymen with Hematocolpometra / 대한산부인과학회지

Imperforate hymen is a rare congenital malformation, but it can make hematocolpometra and complications. In most cases definite finding is noticed after menarche as retention of menstrual flow results in abdominal pain, distension of the lower abdomen and often in acute urinary retention. A case of imperforate hymen associated with hematocolpometra at age of 12 was treated satisfactorily by simple crucial incision of hymen and drained of about 450 cc of tarry blood. We present a case of imperforate hymen with a brief review of literatures concerned.

A Case of Metastatic Ovarian Adenocarcinoma in Pregnancy / 대한산부인과학회잡지

Metastatic ovarian adenocarinoma (Krukenberg tumor) is rare ovarian neoplasm and hard to detect early. The tumor characterized by the infiltration of the interstitium and the signet ring cell was metastasized from GI tract, predominantly. Gastroscopy should be performed in pregnant women with persistent gastro-intestinal complaints after the first trimester. We have experienced a case of metastatic ovarian adenocarcinoma at near term pregnancy, and report this case with a brief review of the concerned literatures.

Three Cases of Endometriosis in the Abdominal Scar Following Cesarean Section / 대한산부인과학회잡지

Endometriosis in the abdominal scar following cesarean section is very rare condition among the extrapelvic endometriosis. Abdominal wall endometriosis secondary to cesarean section is being reported in less than 0.5% of patients undergoing cesarean section and has a distinct presentation and treatment. Three patients with history of cesarean section presented with a painful, enlarging mass involving the cesarean section scar. The pain was cyclic and the strongest just prior to menstruation. These patients were treated with surgical excision and specimens had endometriosis confirmed by histopathology. We have experienced three cases of endometriosis in the abdominal scar following cesarean section. So, we report the cases with a brief review of the concerned literatures.

A Study of the Prepregnancy Body Mass Index and Two-month-postpartum Weight Loss in the Uncomplicated Term Pregnancy / 대한산부인과학회잡지

OBJECTIVE: To determine the mean two-month-postpartum weight loss, standard deviations and the 10th, 25th, 50th, 75th, and 90th percentiles in the uncomplicated term pregnancy and to examine association between prepregnancy body mass index and two-month-postpartum weight loss. METHODS: We analyzed the two-month-postpartum weight loss data from 175 women who had healthy singleton term pregnancy in Han-il Hospital (Jan 2002-Dec 2002). Data were categorized in three groups according to body mass index. RESULTS: Mean two-month-postpartum weight loss was 9.46 +/- 3.42 kg. There was no statistically significant difference between prepregancy BMI groups and two-month-postpartum weight loss. The more weight gained during pregnancy, the more that was lost at two-month-postpartum. Parous women retained more of their pregnancy weight. Compared with women who delivered vaginally, women who delivered cesarean experienced greater weight loss at two-month-postpartum. CONCLUSION: More careful postpartum care according to the two-month-postpartum weight loss table is needed to prevent long-term obesity.

A Case of Primary Ovarian Pregnancy / 대한산부인과학회잡지

Ovarian pregnancy is a rare form of ectopic pregnancy that is often difficult to diagnose. The diagnostic criteria were described in 1878 by Spiegelberg, which comprise that the pregnancy is in the ovary and does not involve the tube. Ovarian pregnancy occurs in the corpus luteum, and is usually accompanied with the rupture of the ovary and massive hemoperitoneum. It presents as a hemorrhagic ovary and frequently misdiagnosed as a ruptured corpus luteum. We have experienced a case of ovarian pregnancy and reviewed it briefly.

A Study of the Monthly Weight Gains of Noncomplicated Pregnancies / 대한주산의학회잡지

OBJECTIVE: Mean weight gains, standard deviations were calculated for each gestational months and the 10th, 25th, 50th, 75th, and 90th percentiles were determined. And the influence of prepregnancy body mass index and/or parity on monthly weight gain was investigated. METHODS: We analyzed the monthly weight gain data from 876 women who had healthy sigleton term pregnancy in Han-il Hospital(Jul 2001-Jun 2002). Data were categorized in three groups according to the prepregnancy body mass index. RESULTS: The monthly weight gain table has been determined and 'Sigmoid(S) shaped' monthly weight gain curve was presented. Primipara and multipara have less weight gain than nullipara in the 5th and the 7th-11th months. Monthly weight gains adjusted for parity and age were significantly different among prepregnancy body mass index groups from the 4th month. CONCLUSIONS: More careful prenatal care according to the monthly weight gain-gestational month tables is needed to prevent a lot of complications which may be associated with abnormal weight gain during pregnancy.

A Case of Ruptured Rudimentary Uterine Horn Pregnancy / 대한산부인과학회잡지

The incidence of pregnancy in a rudimentary uterine horn is very rare. We experienced a case of ruptured rudimentary uterine horn pregnancy in the second trimester. The patient was treated by resection of the ruptured horn. Some articles concerned to this subject are reviewed briefly.

A Case of Heterotopic Pregnancy after Tubal Reanastomosis / 대한산부인과학회잡지

Heterotopic pregnancy is the coexistence of intrauterine and extrauterine pregnancy. It is a rare obstetrical phenomenon with an incidence rate about 0.003%. The risk factors of heterotopic pregnancy are IUD, PID, endometriosis, tubal surgery, etc resulting in functional and anatomical injury to tubes. Recently, the wide use of ovulation induction and in vitro fertilization has increased the incidence rate. The clinical manifestation are low abdominal pain, adnexal mass, peritoneal irritation signs, vaginal bleeding, etc. Early detecion of heterotopic pregnancy is very difficult. However, recently, due to development of pelviscopy, ultrasonogram and other diagnostic procedures, the diagnostic rate has increased.Because of the high maternal morbidity and mortality resulted from intraabdominal bleeding after rupture of ectopic pregnacy, immediate termination of ectopic pregnancy is required usually by operative methods. We experienced a case of heterotopic pregnancy after tubal reanastomosis and report this case with a brief review of literatures.

One Case of Prenatal diagnosed 48, XXYY / 대한산부인과학회잡지

Despite the rarity of 48, XXYY, having an incidence rate of 1 in 50,000 persons, 1 in 300 persons are reported to have a mental disorder of criminal behavior. The clinical characterics of 48, XXYY are similar to Klinefelter's syndrome such as small testis, tall stature, gynecomastia and can show mental retardation and skeletal anomaly. When the cause of elevated maternal serum AFP is not explained by USG or measurement of amniotic fluid AFP, during the second trimester of pregnancy, it is defined as unexplained elevation of maternal serum AFP. We report a case of 48, XXYY with unexplained elevation of maternal serum AFP which has been experienced in our hospital with brief review of literature.

A Case of Cervical Pregnancy treated by Intraamniotic Injection of Methotrexate Guided by Transabdominal Ultrasonography / 대한산부인과학회잡지

Cervical pregnancy is a rare form of ectopic gestation and it can cause serious bleeding, shock and death. Although hysterectomies are still performed due to massive hemorrhages, there are some conservative approaches to cervical pregnancies to conserve fertility. Methotrexate is a very useful agent in the management of trophoblastic disease, and has been utilized recently for the successful management of tubal, interstitial, and cervical ectopic gestations. We report a case of viable cervical pregnancy treated successfully with intraamniotic injection of methotrexate guided by transabdominal ultrasonography.

Two Cases of Hyperemesis Gravidarum Managed by Enteral Feeding via Nasogastric Tube / 대한산부인과학회잡지

Traditionally, total parenteral nutrition(TPN) has been used when patients with hypaemesis gravidarum failed to respond to conservative management, but now many physicians attempt to enteral feeding via nasogastric tube because TPN is expensive and has many complications. Recently, we experienced 2 cases of hyperemesis gravidarum successfully managed by enteral feeding via nasogastric tube, therefore we think that this method may be carefully considered to the patients with hyperemesis gravidarum failed to respond to conservative management. So we report them with brief review of the literatures.
