Abstract
AIMS Gestational diabetes (GDM) is often accompanied by maternal overweight. Our aim was to evaluate the separate and concomitant effects of GDM and maternal overweight/obesity on perinatal outcomes. METHODS We used the Finnish Medical Birth Register to identify all 24,577 women with a singleton pregnancy who delivered in 2009 in Finland and underwent an oral glucose tolerance test (OGTT). Women were divided into groups according to the result of OGTT (GDM/no GDM) and pre-pregnancy body mass index (BMI): normal weight (≤24.9 kg/m2), overweight (25.0-29.9 kg/m2), and obese (≥30.0 kg/m2). Primary outcomes included macrosomia, caesarean delivery, and treatment at neonatal ward. Normal weight women without GDM constituted the reference group. RESULTS Compared to reference group, overweight or obese women without GDM had an increased risk of macrosomia [odds ratio adjusted for age, parity, smoking and socio-economic status (aOR)1.18 (95% CI 1.09-1.28) and 1.50 (95% CI 1.19-1.88)], and caesarean delivery [aORs 1.17 (95% CI 1.07-1.28) and 1.52 (95% CI 1.37-1.69)], respectively. In normal weight GDM women the risk of macrosomia [aOR 1.17 (95% CI 0.85-1.62)] and caesarean delivery [aOR 1.10 (95% CI 0.96-1.27)] was not significantly increased as compared to normal weight women without GDM. GDM increased the risk of treatment at neonatal ward in all BMI categories and maternal obesity without GDM was also a risk factor for treatment at neonatal ward. Interaction p values between BMI and GDM on these outcomes were <0.001. CONCLUSIONS Maternal overweight and obesity without GDM increased the risk of macrosomia and caesarean delivery when compared to the reference group. These risks were amplified when overweight/obesity was accompanied by GDM. Obesity without GDM was a risk factor for treatment at neonatal ward; GDM increased this risk in all BMI categories. Our results suggest that especially maternal obesity should be considered as a risk factor for adverse pregnancy outcomes and GDM further amplifies this risk.

Abstract
One out of seven of all parturients and one out of five primigravid women deliver by caesarean section. Of four women having undergone caesarean section, three will give birth vaginally, provided that the indication for surgery has been temporary by nature. Spontaneous beginning of labor and a previous vaginal delivery improve the chances of succesful of vaginal delivery. Rupture of the uterus in subsequent pregnancies is the most feared sequel to a caesarean section, with an occurrence of 0.2 to 1.5%. Delivery by caesarean is indicated in case of previous rupture of the uterus, hysterotomy through vertical incision, and more than two previous caesarean sections.

Abstract
Objectives To compare the Foley catheter and misoprostol for induction of labor in term women with premature rupture of membranes. Study Design A randomized controlled trial was performed in three university hospitals in Finland between March 2012 and September 2014. A total of 202 term women with ruptured membranes >18 hours, singleton pregnancies in cephalic presentation, unfavorable cervix, and no prior cesarean section were enrolled. Participants were randomly allocated to induction of labor by Foley catheter or oral misoprostol in a 1:1 ratio. All women received prophylactic antibiotics. The main outcomes were cesarean section and maternal and neonatal infections. Results Labor induction by Foley catheter or misoprostol showed no difference in cesarean delivery rates (23.6 vs. 18.2%; odds ratio [OR], 1.39; 95% confidence interval [CI], 0.69-2.82; p = 0.36), maternal intrapartum infections (2.2 vs. 2%; OR, 1.12; 95% CI, 0.15-8.9; p = 1.00), postpartum infections (1.1 vs. 2.0%; OR, 0.55; 95% CI, 0.05-6.18; p = 1.00), or neonatal infections (1.1 vs. 5.1%; OR, 0.21; 95% CI, 0.24-1.87; p = 0.22). The total time from induction to delivery was similar (1,311 vs. 1,435 minutes; p = 0.31) in the two groups. Conclusions Foley catheter or misoprostol can both be used for induction of labor in women with term premature rupture of membranes.

Abstract
Finnish grand multiparae (4 to 7 previous childbirths) use maternal care services to the same extent, weigh more and smoke less compared with primigravidae and multiparae (1 to 3 previous childbirths). Problems in pregnancy and delivery are least common in multiparae. Frequency of the hypertension problem in grand grand multiparae (8 or more previous childbirths) is 1.3-fold and the risk of ablation in all grand multiparae approximately 1.5-fold higher in comparison with multiparae. Compared with primigravidae and multiparae, childbirths by grand multiparae proceed in a more regular manner, although the number of induced labors is higher with the latter.

Abstract
OBJECTIVE Gestational diabetes mellitus (GDM) is associated with an increased risk of subsequent diabetes and metabolic syndrome (MS). The independent significance of overweight, often associated with GDM, is controversial. This study was aimed to investigate the prevalence of MS and carotid intima-media thickness (CIMT) values in normal and overweight women with previous insulin-treated GDM and control without GDM 19 years after the index pregnancy. METHODS The study group consisted of 61 women with prior GDM and 55 controls who gave birth in Oulu University Hospital between 1988 and 1993. These women were further divided into subgroups according to pre-pregnancy BMI (<25 or ≥25 kg/m(2)). In 2008-2010, anthropometrics and blood pressure were measured, blood samples were taken, and an oral glucose tolerance test was performed to investigate the components of MS. CIMT was measured by Doppler ultrasound. RESULTS Total prevalence of MS was 62% in the GDM group and 31% in the control group (P=0.001); it was highest (86%) in GDM women with pre-pregnancy overweight. CIMT was significantly thicker (0.67 vs 0.56 mm, P=0.007) and more often abnormal (71.7 vs 45.3%, P=0.004) in the GDM group compared with the controls. In logistic regression analysis, the strongest factor predicting MS in the whole study population was pre-pregnancy overweight. CONCLUSIONS Pre-pregnancy overweight was the strongest predictive factor for later MS, whereas GDM indicated increased risk of subsequent diabetes and subclinical atherosclerosis. The risk of MS was highest when both of these factors were present.

Abstract
OBJECTIVE The aim of this study was to compare the rate of cesarean sections in 12 delivery units in Finland, and to assess possible associations between cesarean section rates and maternal and neonatal complications. DESIGN Prospective multicenter cohort study. SETTING The 12 largest delivery units in Finland. POPULATION Total obstetric population between 1 January 2005 and 30 June 2005 (n = 19 764). METHODS Prospectively collected data on 2496 cesarean sections and data derived from the Finnish Birth Register on all deliveries in these units were compared. Cesarean section rates and maternal complication rates were adjusted for known risk factors. MAIN OUTCOME MEASURES Cesarean section rate, maternal complications related to cesarean section, and neonatal asphyxia. RESULTS The cesarean section rates varied significantly between the hospitals (12.9-25.1%, p < 0.0001), as did the maternal complication rates related to cesarean section (13.0-36.5%, p < 0.0001). There was no relation between maternal complications and the cesarean section rate. The differences remained after adjusting for risk factors. Neonatal asphyxia rates varied between 0.14 and 2.8% (p < 0.0001) and were not related to the cesarean section rates. CONCLUSIONS The rates of cesarean section, maternal complications and neonatal asphyxia vary markedly between different delivery units. Good maternal and neonatal outcomes can be achieved with cesarean section rates <15%.

Abstract
BACKGROUND Remifentanil labour analgesia is superior to nitrous oxide but less potent than epidural analgesia. The short onset and offset times of effect suggest that the timing of the bolus in the contraction cycle could have importance. We hypothesised that administering a remifentanil bolus during contraction pause would improve analgesia in early labour. METHODS With permission from the ethical committee and the National Authority of Medicines, 50 parturients with uncomplicated singleton pregnancies and informed consent participated in a double blind cross-over study. Intravenous doses of 0.4 μg/kg remifentanil with 1-min infusion times were used during two study periods lasting six to eight contractions. Remifentanil and saline syringes were attached to two patient-controlled devices, one of which administered the bolus immediately after a trigger and the other targeted to start 140 s before the next contraction. The parturients assessed contraction pain, pain relief, sedation and nausea. Oxygen saturation (SaO(2)) pulse and blood pressure were recorded. SaO(2)<95% was the indication for oxygen supplement. RESULTS Forty-one parturients were included in the analyses. Because of the period effect, pain and pain relief scores were analysed separately for each of the study periods. The mean pain and pain relief scores were similar during the two different dosing regimens. Side effects, the need for supplemental oxygen, SaO(2) and haemodynamics were similar. In a subgroup with long and regular contractions, however, delayed boluses were associated with lower pain scores. CONCLUSIONS Administering a remifentanil bolus during the uterine contraction pause does not improve pain relief.

Abstract
OBJECTIVE To examine if oral metformin is as effective as insulin in the prevention of fetal macrosomy in pregnancies complicated with gestational diabetes mellitus (GDM). DESIGN Open-label prospective randomised controlled study. SETTING Maternity outpatient clinics in a secondary and tertiary level hospital in Finland. SAMPLE One hundred women with GDM who did not attain euglycaemia with diet. METHODS Women were randomised to therapy with insulin (n = 50) or oral metformin (n = 50). MAIN OUTCOME MEASURES Incidence of large-for-gestational-age (LGA) infants and neonatal morbidity. RESULTS There were no statistically significant differences in the incidence of LGA (8.5 versus 10.0%, P = 0.97), mean birthweight, mean cord artery pH or neonatal morbidity between the insulin and metformin groups. Fifteen (31.9%) of the 47 women randomised to metformin needed supplemental insulin. They were more obese (with a body mass index of 36 versus 30 kg/m(2), P = 0.002), had higher fasting blood glucose levels in an oral glucose tolerance test (6.1 versus 5.0 mmol/l, P = 0.001) and needed medical treatment for GDM earlier (26 versus 31 gestational weeks, P = 0.002) than women who were normoglycemic with metformin. There was a tendency to a higher rate of caesarean sections in the metformin group than in the insulin group (RR 1.9; 95% CI 0.99-3.71). CONCLUSIONS Metformin seems to be suitable for the prevention of fetal macrosomy, especially in lean or moderately overweight women developing GDM in late gestation. Women with considerable obesity, high fasting blood glucose and an early need for pharmacological treatment may be more suitable for insulin therapy.

Abstract
Abdominal pregnancy is a rare form of ectopic pregnancy with potentially life-threatening complications both to mother and the fetus. Due to infrequency of abdominal pregnancy, it is often unsuspected and remains a diagnostic challenge despite improvements in imaging techniques. We report a case of advanced abdominal pregnancy after in vitro-fertilization. The diagnosis was made by magnetic resonance imaging (MRI) at 30 weeks' gestation, and a healthy baby was successfully delivered by laparotomy. The mother and the baby survived without any long-term complications.

Abstract
BACKGROUND We hypothesised that intravenous patient-controlled analgesia (IV PCA) with remifentanil could provide as satisfactory pain relief for labour as epidural analgesia. METHODS Fifty-two parturients with singleton uncomplicated pregnancies were randomised to receive either IV PCA with remifentanil or epidural analgesia with 20 ml levobupivacaine 0.625 mg/ml and fentanyl 2 microg/ml in saline. The PCA dose of remifentanil was given over 1 min with a lockout time of 1 min. The dose was increased starting from the bolus of 0.1 microg/kg and following a dose escalation scheme up until the individual-effective dose was reached. The parturients assessed contraction pain (0-10), pain relief (0-4), sedation and nausea during 60 min. RESULTS Forty-five parturients were included in the analysis. The median cervical opening was 4 cm before the study and 7 cm after the study. The median pain scores were 7.3 and 5.2 during remifentanil and epidural analgesia, respectively (P=0.009). The median pain relief scores were 2.5 and 2.8 (P=0.17). There was no difference between the groups in the proportion of parturients who discontinued due to ineffective analgesia, nor in the proportion of parturients who would have liked to continue the given medication at the end of the study. Sedation and low haemoglobin oxygen saturation were observed more often during remifentanil analgesia. Foetal heart rate tracing abnormalities were as common in both groups. CONCLUSIONS In terms of pain scores, epidural analgesia is superior to that provided by IV remifentanil. However, there was no difference in the pain relief scores between the treatments.

Abstract
BACKGROUND To evaluate indications, efficacy, and complications associated with arterial embolization and prophylactic balloon catheterization in the management of obstetric hemorrhage at a university hospital. METHODS Twenty-two women underwent arterial embolization between February 2001 and November 2003 for the treatment for primary postpartum hemorrhage resulting from abnormal placentation (n=11), uterine atony (n=7), paravaginal laceration (n=3), and disseminated intravascular coagulopathy (n=1). Blood loss was between 3.2 and 15 l. In seven patients, abnormal placentation was diagnosed prenatally and in these patients balloon catheterization was performed prophylactically before elective cesarean section. RESULTS Of the seven patients, who underwent prophylactic catheterization, embolization was successful in five resulting in adequate hemostasis. Hysterectomy was performed in three, in two patients for uncontrolled hemorrhage and in one patient for placental invasion to bladder. There were no complications associated with prophylactic catheterization and embolization. The other 15 patients were treated in an emergency setting. In eight patients, embolization was performed as a primary surgery, and it was successful in six. In the other seven patients, hysterectomy was performed as an emergency surgery, but bleeding continued. Of these, in six patients, hemostasis was achieved with embolization. Complications associated with emergency embolization were observed in three patients. These were thrombosis of left popliteal artery, vaginal necrosis, and paresthesia of the right leg. CONCLUSIONS Arterial embolization is of significant value in treating obstetric hemorrhage. Prophylactic insertion of balloon catheters before cesarean section seems to be a safe and effective method in controlling anticipated bleeding. In patients with persistent bleeding following cesarean section and hysterectomy, embolization could be a primary procedure before re-surgery.

Abstract
OBJECTIVE To compare the risk for congenital malformations in offspring between women with epilepsy being treated with antiepileptic drugs (AEDs) during pregnancy and those who discontinued their antiepileptic medication before pregnancy in a population-based cohort of female patients with epilepsy. METHODS All patients with epilepsy (n = 20,101) eligible for AED reimbursement for the first time during 1985 to 1994 were identified from the Social Insurance Institution of Finland. Information on births during 1991 to 2000 was obtained from the National Medical Birth Registry. Information on AED use during pregnancy and on pregnancy outcomes was abstracted from medical records. RESULTS Congenital malformations were more common among offspring of women on antiepileptic medication (65/1,411; 4.6%) than among offspring of untreated patients (26/939; 2.8%) (p = 0.02). The risk of malformations was substantially higher in the offspring of patients using valproate as monotherapy (OR = 4.18; 95% CI: 2.31, 7.57) or valproate as polytherapy (OR = 3.54; 95% CI: 1.42, 8.11) than of untreated patients. Polytherapy without valproate was not associated with increased risk of malformations. CONCLUSION Excess risk was confined to patients using valproate during pregnancy. The risk for malformations was not elevated in offspring of mothers using carbamazepine, oxcarbazepine, or phenytoin (as monotherapy or polytherapy without valproate).

Abstract
BACKGROUND We compared the efficacy and side-effects of remifentanil with those of nitrous oxide during the first stage of labour. METHODS Twenty parturients participated in a randomized, double-blind, cross-over study. Intravenous remifentanil in 0.4 microg kg(-1) PCA doses with 1-min infusion and lock-out times and intermittent inhaled 50% nitrous oxide were compared during 20-min study periods with a 20-min wash-out sequence after each period. The parturients assessed the intensity of contraction pain (verbal numerical score 0-10), pain relief (score 0-4) and side-effects every 10 min. Noninvasive blood pressure, heart rate (HR), oxyhaemoglobin saturation (SaO2), end-tidal carbon dioxide, fractions of inhaled and exhaled oxygen and nitrous oxide and foetal heart rate (FHR) were recorded. Hypoxaemia and bradycardia were defined as SaO2<90% and HR<50, respectively. RESULTS Fifteen parturients completed the study. There was no period effect or treatment-period interaction. The median decrease in pain score for remifentanil was 1.5 and that for nitrous oxide 0.5 (P=0.01). The parturients gave better pain relief scores with remifentanil than with nitrous oxide (median 2.5 vs. 0.5, respectively, P<0.001). Sedation was reported more often, and SaO2 was slightly lower during remifentanil administration. No episodes of hypoxaemia occurred. There was no difference in maternal blood pressure and HR or the incidence of abnormal FHR during remifentanil compared to nitrous oxide. Most parturients preferred remifentanil to nitrous oxide (14 vs. 1, P<0.001). CONCLUSIONS This study suggests that IVPCA remifentanil provides better labour analgesia than intermittently inhaled nitrous oxide.

Abstract
OBJECTIVE AND METHODS To study the effects of hormone replacement therapy on glucose metabolism, 31 obese (body mass index > or =27 kg/m(2)) postmenopausal women were randomized to treatment with tibolone (2.5 mg once daily; TIB; n=16) or to oestradiol valerate (2 mg daily)-dydrogesterone (20 mg daily for 2 weeks every 3 months; ED; n=15) for 12 months. Oral (OGTTs) and intravenous glucose tolerance tests (IVGTTs) and a euglycaemic hyperinsulinaemic clamp were performed before and at 6 and 12 months of treatment. RESULTS TIB decreased the rates of whole body glucose uptake (WBGU) at 6 (P=0.04) and 12 months (P<0.001), but it did not have a significant effect on glucose tolerance. In OGTTs, serum insulin and C-peptide concentrations 2 h after the oral glucose load were increased (P<0.001 and P=0.05 respectively) at 12 months of treatment with TIB, but no changes in the areas under the curve (AUC) of insulin or C-peptide were observed. Furthermore, TIB did not have a significant effect on insulin secretion, the metabolic clearance rate (MCR) of insulin or hepatic insulin extraction. Treatment with ED did not modify the rates of WBGU, but it increased the MCR of insulin (P=0.017) and hepatic insulin extraction (P<0.001) and tended to decrease the insulin AUC (P=0.07). Moreover, glucose tolerance slightly deteriorated during this treatment (P=0.02). Although early phase insulin secretion evaluated by the serum C-peptide response at 30 min in the OGTT increased (P=0.046), the first-phase insulin response during the IVGTT decreased (P=0.05) during ED treatment. CONCLUSIONS Despite the impairment in peripheral insulin sensitivity, TIB treatment had a neutral effect on glucose tolerance, possibly due to a compensatory decrease in endogenous glucose production. The increased demand on insulin induced by ED, due to both a stimulatory effect on pancreatic beta cells and increased insulin metabolism, may explain the slightly detrimental effect on glucose tolerance with this treatment.

Abstract
BACKGROUND To test the hypothesis that sufficient pain relief during delivery decreases the risk of postnatal depression. METHODS As part of a prospective follow-up study of the risk factors for postnatal depression and its impact on the mother-infant interaction and child development, 185 parturients filled in the Edinburgh Postnatal Depression Scale (EPDS), first during the first postpartum week and again (n = 162) 4 months later. The incidence and the risk of high EPDS scores was calculated according to the mode of delivery and the mode of pain relief during vaginal delivery, also after adjusting for the length of labor. RESULTS Mothers who received epidural/paracervical blockade during their delivery spent less time in the delivery room than mothers in the nitrous oxide/acupuncture group (p = 0.033) or mothers with no pain relief (p = 0.026) and had shorter length of labor than mothers without pain relief (p = 0.04). The adjusted risk of depressive scores at the first postnatal week was decreased in the epidural/paracervical group when compared with no analgesia group (OR: 0.25, 95% CI: 0.09-0.72). This difference was not shown at 4 months postpartum. Elective or emergency cesarean section did not increase the risk of high EPDS scores at the first week or at 4 months postpartum. CONCLUSION The mode of pain relief during vaginal delivery seems to be associated with the incidence of postpartum depression, especially immediately after delivery.

Abstract
UNLABELLED IV patient-controlled analgesia (PCA) with remifentanil is a new approach in systemic opioid analgesia during labor. We determined the minimum effective dose of IV remifentanil by increasing the PCA bolus from 0.2 microg/kg with 0.2 microg/kg increments during a 60-min study period until the analgesia was considered adequate by the parturient. Twenty healthy parturients with singleton pregnancies participated in the study during the first stage of labor. Remifentanil hydrochloride was given IV via PCA over 1 min with a lockout time of 1 min. The parturient started the PCA bolus at the first subjective sign of uterine contraction. All 17 patients who completed the study reached adequate pain relief. The median effective PCA bolus was 0.4 microg/kg and consumption was 0.066 microg x kg(-1) x min(-1), with wide individual variation (0.2-0.8 microg/kg and 0.027-0.207 microg x kg(-1) x min(-1), respectively). The pain scores were reduced by a median of 4.2 (25th-75th percentiles, 3.1-5.2; P < 0.001) on an 11-point numeric scale. Although there was a wide individual variation in the dose required, remifentanil seems effective for labor analgesia. However, maternal oxygen desaturation, sedation, and reduced fetal heart rate beat-to-beat variability were observed frequently. There was wide individual variation in the dose required for effective labor analgesia. Potentially serious side effects, which were observed frequently during remifentanil analgesia, may limit remifentanil's use in obstetrics. IMPLICATIONS We determined the minimum effective dose of patient-controlled IV remifentanil for labor analgesia. There was wide individual variation in the dose required for effective labor analgesia. Potentially serious side effects, which were observed frequently during remifentanil analgesia, may limit its use in obstetrics.

Abstract
OBJECTIVE The clinical and endometrial efficacy and lipid response of two different doses of intrauterine levonorgestrel were assessed in comparison with sequential oral medroxyprogesterone acetate in postmenopausal women receiving continuous oral E2-valerate. DESIGN One-year prospective multicentre randomised control trial. SETTING Four outpatient clinics in Oulu, Helsinki and Jyväskylä, Finland. POPULATION A total of 163 healthy volunteer postmenopausal women with climacteric complaints or already using hormone replacement therapy (HRT). INTERVENTIONS Subjects were randomly allocated to receive a new intrauterine system releasing 10 microg of levonorgestrel daily or an established intrauterine system (Mirena) releasing 20 microg of levonorgestrel daily or sequential oral medroxyprogesterone acetate (5mg/day, 14/30 days). All three regimens were combined with an oral daily dose of 2mg of E2-valerate. MAIN OUTCOME MEASURES Bleeding patterns were assessed by diaries kept by the subjects. Endometrial effects were evaluated by histologic biopsies taken at the baseline and after six and 12 months of therapy. Serum concentrations of total, HDL and LDL cholesterol, triglycerides and lipoprotein(a) were determined at the baseline and after six and 12 months of therapy. RESULTS Insertion of the smaller 10 microg levonorgestrel system was easy in 70% and difficult in 4% and that of Mirena was easy in 46% and difficult in 21% of the subjects. After six months of therapy, 43 (95.6%) of the 47 subjects receiving 10 microg levonorgestrel and 54 (98.2%) of the 55 subjects receiving 20 microg levonorgestrel had no bleeding, while the sequential medroxyprogesterone acetate regimen produced typical cyclic withdrawal bleedings. Endometrial hyperplasia was not observed in any of the treatment groups during the 12-month study. After 12 months of therapy, strong endometrial suppression was found in 46/47 and 55/55 of the subjects receiving 10 microg and 20 microg of levonorgestrel, respectively, while the endometrium was proliferative in 18/47 of the subjects in the medroxyprogesterone acetate group. Serum total cholesterol decreased in all treatment groups. HDL cholesterol increased in women receiving medroxyprogesterone acetate or the smaller intrauterine dose of levonorgestrel. CONCLUSIONS Both intrauterine doses of levonorgestrel provided good endometrial protection in postmenopausal women on oestrogen replacement therapy. The advantage of the 10 microg system with a smaller size is the easier insertion of the system and a minimal attenuation of the favourable effects of oral oestrogen on the serum lipid profile.

Abstract
BACKGROUND The study was devised to measure the effect of intrauterinely delivered levonorgestrel and transdermal estradiol on insulin sensitivity in postmenopausal women and compare this effect with that induced by transdermal estradiol alone. METHODS An open, prospective, comparative study of healthy postmenopausal women without earlier use of hormone replacement therapy. The estrogen therapy group consisted of eight hysterectomized women, who used a transdermal patch delivering a daily dose of 50 microg of estradiol continuously for 6 months. The estrogen-progestin therapy group consisted of 13 women with an intact uterus, who received a simultaneous combination of a transdermal patch and a levonorgestrel (20 microg/day) intrauterine system for the same length of time. Fasting plasma concentrations of glucose, insulin and C-peptide and an insulin tolerance test were used to measure glucose metabolism and insulin sensitivity. RESULTS Neither therapy changed the fasting plasma levels of glucose, insulin or C-peptide. Transdermal estrogen improved insulin sensitivity by 22%, as measured by an insulin tolerance test, while a small increase of 3.6% was observed using the combination therapy. CONCLUSIONS Transdermal estradiol improves insulin sensitivity in healthy postmenopausal women. Combining intrauterine levonorgestrel to transdermal estradiol reverses this effect. This combination does not, however, seem to induce insulin resistance.

Abstract
OBJECTIVE We determined the effects of continuous combined nonoral and oral estrogen-progestin therapy on plasma levels of insulin-like growth factor-I (IGF-I) and its binding proteins 1 (IGFBP-1) and 3 (IGFBP-3). DESIGN Forty women complaining of climacteric symptoms were randomized to receive either transdermal estradiol patches (50 microg daily) in combination with an intrauterine system releasing 20 microg of levonorgestrel daily or an established regimen of an oral dose of 2 mg of estradiol and 1 mg of norethisterone acetate daily for 1 year. Fifteen women in the nonoral therapy group and 17 in the oral therapy group completed the 1-year prospective study. RESULTS Plasma levels of IGF-I decreased significantly in the oral therapy group, but no changes were observed in the plasma levels of its binding proteins. Transdermal estrogen in combination with intrauterine levonorgestrel did not induce any change in plasma IGF-I, whereas the plasma levels of IGFBP-3 decreased. IGFBP-1 concentrations increased, which may be related to the induction of this protein into the endometrium by the intrauterine levonorgestrel delivery. CONCLUSIONS Both the nonoral and oral continuous combined estrogen-progestin therapies used in this study produced only minor changes in the circulating concentrations of IGF-I and its binding proteins.

Abstract
OBJECTIVES Nonoral administration of hormone replacement therapy avoids the first pass metabolism of steroids in the liver. We wanted to determine to what extent it has an effect on the serum concentrations of sex-hormone binding globulin and the free testosterone index. METHODS Postmenopausal women received 50 microg per day transdermal estradiol associated with the use of a levonorgestrel-releasing intrauterine device (20 women) or a daily oral dose of 2 mg of estradiol and 1 mg of norethisterone acetate (20 women) for 1 year. Eight women, five in the nonoral and three in the oral therapy group discontinued the study. RESULTS Although serum sex-hormone binding globulin concentrations decreased in women receiving transdermal estradiol in combination with a levonorgestrel-releasing intrauterine device, the free testosterone index did not change significantly. In the continuous oral regimen, no significant changes in serum sex-hormone binding globulin or free testosterone index were observed. The free testosterone index, however, was significantly higher in the nonoral therapy group after 6 and 12 months of treatment than in the oral therapy group. CONCLUSIONS Continuous progestin combined with continuous estrogen in oral and nonoral replacement therapy does not lead to a substantial androgenic excess in postmenopausal women. The intrauterine administration of levonorgestrel appears to have some hepatic effect.

Abstract
The aim of this study was to determine the effect of continuous intrauterine release of progestin on the uterine artery pulsatility index (PI) in women on postmenopausal hormone replacement therapy (HRT). The voluntary participants, 13 symptomatic postmenopausal women received transdermal estradiol (50 micrograms/day) for 1 month before combining the levonorgestrel-releasing (20 micrograms/day) intrauterine system (LNG-IUS) with estrogen replacement therapy. The PI of uterine artery blood flow was measured by transvaginal color Doppler ultrasonography before the onset of HRT, 1 month after the treatment with estradiol (estradiol-only phase) and 1, 3 and 6 months after insertion of the LNG-IUS. The mean uterine artery PI decreased significantly from its pretreatment level after 1 month of transdermal estradiol treatment (p < 0.05), but the LNG-IUS induced an increase in PI, and 6 months after its insertion the PI did not differ significantly from the pretreatment level (p > 0.05). Compared with the estradiol-only phase, the last measurement of the PI was significantly increased (p < 0.05). The results suggest that continuous intrauterine release of levonorgestrel abolishes the vasodilatory effect on the uterine arteries accomplished by postmenopausal estradiol treatment.

Abstract
OBJECTIVES To study the effect of postmenopause and postmenopausal hormone replacement therapy (HRT) on the measured fundamental frequency (F0) and sound pressure level (SPL) of sustained phonation and speaking voice samples and on subjective vocal/laryngeal symptoms. METHODS Forty-three postmenopausal women (mean age 51.6) were divided into three groups: a group with no HRT, an estrogen group (daily oral dose of 2 mg of estradiol valerate), and an estrogen-progestin group (daily oral dose of 2 mg of 17-B-estradiol and 1 mg of northisterone acetate). Voice measurements were made before and after 1 year of treatment. Subjective symptoms were registered using a questionnaire. RESULTS The mean F0 and SPL decreased significantly in the group with no HRT in spontaneous speech and reading samples as did SPL in the normal phonation sample. In both groups with HRT, the mean F0 decreased significantly only in the spontaneous speech sample and the decrease was smaller than in the group with no HRT. The mean SPL decrease in the estrogen group was significant in the normal phonation sample while in the estrogen-progestin group it was significant in both the normal phonation and the reading sample. The number of subjective symptoms was smallest in the estrogen group. CONCLUSIONS The changes in the measured voice values and the subjective symptoms experienced suggest that at least the early postmenopausal years are associated with vocal changes and that HRT counteracts this phenomenon. This seems to be more pronounced with estrogen than with a combination of estrogen and progestin.

Abstract
OBJECTIVES To investigate the effect of estrogen alone or combined with progestin on the amount and synthesis of skin collagen in postmenopausal women. METHODS Forty-three early postmenopausal women were enrolled into this open, non-randomized parallel-groups study. Fifteen women received a continuous oral dose of 2 mg of 17 beta-estradiol and 1 mg of norethisterone acetate daily and 14 women an oral dose of 2 mg estradiol valerate daily. Fourteen subjects served as controls. The histology and type I and III procollagen immunohistochemistry of the skin, skin thickness, the amount of total collagen determined by a colorimetric method and the synthesis of type I and III collagens determined by analysing procollagen propeptides in the suction blister fluid were studied before the treatment and at 6 and 12 months. The proportional area of elastic fibers and the thickness of the epidermis were assessed from the sections obtained before the treatment and at 12 months, with computerized image analysis. RESULTS Skin thickness, the amount and rate of collagen synthesis, the proportional area of elastic fibers and the thickness of the epidermis were not affected by either 17 beta-estradiol and 1 mg of norethisterone acetate or 2 mg of estradiol valerate. No histological or immunohistological changes were detected in the skin specimens during the 12-month treatment period compared to the baseline or to the skin specimens of the control group. CONCLUSIONS A 1-year treatment with systemic estrogen alone or combined with progestin does not change the amount of collagen or the rate of collagen synthesis in postmenopausal women.

Abstract
In an open, multicentre study, transdermal administration of oestradiol (E2) by means of skin patches was investigated in a Finnish patient population suffering from typical post-menopausal symptoms. A total of 249 women applied a patch twice weekly for 6 months. Whereas 85% of the subjects were experiencing hot flushes and 83.5% sweating before therapy, only 5.7% and 11.8%, respectively, reported these symptoms at the end of the trial. Furthermore, 97.6%, 95.7% and 94.8% of the subjects reported that depression, headache and sleep disturbances, respectively, had disappeared during therapy. Skin irritation occurred in 18.2% of these predominantly fair-skinned women. Frequent sauna bathing did not interfere with the patch therapy. General acceptance of the treatment was excellent, 84.8% of the patients completing the treatment, of whom 78% were willing to continue the treatment after the trial. These results show that transdermal administration of E2 is effective in relieving post-menopausal symptoms. Local tolerability was good and the majority of the patients considered the transdermal treatment to be superior to their previous oral replacement therapy.
