RESUMEN
OBJECTIVES: To evaluate the maternal serum ischemia-modified albumin (IMA) concentration as an oxidative stress biomarker in pregnancies complicated by preterm pre-labor rupture of membranes (PPROM) without maternal clinical infection and compare these results with healthy pregnancies. MATERIAL AND METHODS: The present cohort study included 40 pregnancies complicated by PPROM and 49 similar gestational age healthy pregnancies in the third trimester of gestation. Maternal venous blood specimens were obtained at the day of first diagnosis. Maternal serum IMA level was assayed with an Albumin Cobalt Binding test. The subjects were followed up until delivery and perinatal outcomes were recorded. RESULTS: The maternal serum IMA concentrations were significantly higher in the study group (0.56 ± 0.05 absorbance units) as compared to controls (0.54 ± 0.03 absorbance units) (p = 0.020). The maternal serum IMA concentrations were not significantly correlated with the initial maternal white blood cell count (r: 0.118, p = 0.269) and C-reactive protein levels (r: 0.066, p = 0.541). The maternal serum IMA concentrations were negatively correlated with gestational age at delivery (r: -0.248, p = 0.019), birthweight (r: -0.247, p = 0.020) and Apgar scores (r: -0.200, p = 0.049; r: -0.245, p = 0.020). The threshold value of maternal serum IMA concentration above 0.55 absorbance units indicated the pregnancy complicated by PPROM by 57.5% sensitivity and 57.1% specificity (Area under curve 0.613, confidence interval 0.50-0.73). CONCLUSIONS: The current study supported for the first time that there is an association between increased maternal serum IMA levels and the development of PPROM in the third trimester of gestation without maternal clinical infection. Elevated maternal serum IMA levels may alert the obstetrician about poor ongoing perinatal outcomes in the early phase of PPROM before increased maternal C-reactive protein and white blood cell count.
RESUMEN
OBJECTIVE: Energy drinks have an impact on concentration levels, physical performance, speed of reaction, and focus, but these drinks cause many adverse effects and intoxication symptoms. The main goal of this study was to determine the effect of energy drink consumption on ovarian reserve and serum anti-mullerian hormone (AMH) levels. MATERIALS AND METHODS: Female Wistar albino rats (n=16) were included and randomized into two groups (n=8). Serum AMH levels were checked before and after energy drinks were given. Eight weeks later, the ovaries and uteruses of the rats were analyzed histopathologically. The number of follicles in the ovaries was counted. RESULTS: The total number of the preantral plus small antral follicles, which show the ovarian reserve, was decreased at the end of eight weeks in both the control group and the energy drink group. There was a statistical difference between them (p=0.021). Also, there was a statistically significant difference in the initial/final AMH (ng/mL) reduction levels between the control group and the energy drink group (p=0.002). AMH levels were decreased more in the energy drink group. CONCLUSION: The consumption of energy drinks can lead to a decrease in ovarian reserve and AMH values and may cause weight gain.
RESUMEN
OBJECTIVES: We aimed to investigate the thiol/disulfide balance in ketone positive (hyperemesis gravidarum) and ketone negative pregnant women with nausea and vomiting. MATERIAL AND METHODS: A total of 60 patients under the 14th week of pregnancy were included in this study, and they were divided into two groups. Group 1 included 30 pregnant women with ketone positive, group 2 included 30 ketone negative pregnant women with nausea, and vomiting. RESULTS: The native thiol, disulfide, and total thiol concentrations were measured using an automated method and compared among the two groups. There were also three indexes that are derived from disulfide, native and total thiol (Index 1 = 100 × disulfide/native thiol); (Index 2 = 100 × disulfide/total thiol); (Index 3 = 100 × native thiol/total thiol). When compared with Group 1 and Group 2, total thiol was high, native thiol was low but not statistically significant. Disulphide (p = 0.046), index 1 (p = 0.036) and index 3 (p = 0.034) were statistically significant. CONCLUSIONS: Patients with ketone positive are shifting to OS direction due to lack of nutrients and electrolytes. This study emphasizes the therapeutic potential of antioxidant supplementation, which is becoming an increasingly used approach in treating the symptoms of women with ketone positive.

AIM: The reproductive hormone levels and systemic physiology of women with hepatic cirrhosis are altered. Existing data have indicated the adverse effects of cirrhosis on both the mother and the fetus. Pregnancy is successful in most of the patients with chronic liver disease. But maternal and fetal complication rates are still high for decompensated hepatic cirrhosis. In this study, we aimed to evaluate the clinical features, etiological factors, medications, morbidity, mortality, and obstetric outcomes of pregnant women with hepatic cirrhosis. METHODS: Pregnant women, who were diagnosed with maternal hepatic cirrhosis and followed up in our clinic between 2014 and 2017, were retrospectively evaluated. The pregnant women that had been followed up for hepatic cirrhosis were classified as compensated disease and decompensated disease. Eleven cases were included in this period. RESULTS: The mean age of cases was 33.5 ± 5.5 years. The mean gravida number was 3.2 ± 1.1, and the mean parity number was 1.7 ± 1. Six cases were in the compensated cirrhosis stage, and 5 cases were in the decompensated cirrhosis stage. A pregnancy with decompensated cirrhosis was terminated after the fetal heart sound was negative in the 9th week of pregnancy. Spontaneous abortus occurred in one case (<20 weeks). The mean gestational week of the 9 cases was 33.3 ± 6.2. Two of the 9 cases delivered birth vaginally. Seven cases delivered by cesarean section. The mean first- and fifth-minute APGAR scores were 6.6 ± 1.41 and 8.2 ± 1.56, respectively. The mean birth weight was 2303 ± 981 g. Among 9 cases with live birth, 6 had compensated cirrhosis and 3 had decompensated cirrhosis. In the second trimester, upper gastrointestinal endoscopy was performed to all patients in terms of esophageal varices. Endoscopic band ligation was performed in 3 cases with upper gastrointestinal bleeding. The postpartum mortality did not occur. Discussion. Pregnancy is not recommended for patients with hepatic cirrhosis due to high maternal and fetal morbidity and mortality. The pregnancy course of cases with cirrhosis changes according to the stage of liver injury and severity of disease. Although the delivery method is controversial, delivery by cesarean section is recommended for patients with esophageal varices by the reason of bleeding from varices after pushing during labor. The bleeding risk must be kept in mind as coagulopathy is common in hepatic diseases. The maternal-fetal morbidity and mortality rates have been decreased by the current developments in hepatology, prevention of bleeding from varices with drugs and/or band ligation, improvement in liver transplantation, and increasing experience in this issue.
RESUMEN
BACKGROUND AND AIM: We aimed to compare the levels of clinical, biochemical, hormonal, and metabolic parameters as well as serum CRP, fibrinogen, leptin, and adiponectin in cases with PCOS and control group to investigate whether they play a role in the etiology of the syndrome. MATERIALS AND METHODS: The present study included a total of 90 subjects, 45 subjects were diagnosed with PCOS (n = 45) and 45 subjects served as control group (n = 45). Serum CRP, fibrinogen, leptin, and adiponectin levels were analyzed for each subject. RESULTS: Serum CRP, fibrinogen, and leptin were found to be higher (statistically significant) in the group with PCOS as compared to the control group (p < 0.05). Serum Adiponectin was higher in the control group (statistically significantly) as compared with the patients in the PCOS group (p < 0.05). CONCLUSION: CRP and fibrinogen (cardiac risk factor markers) increase in women with PCOS. The levels of leptin which affects metabolism increase, whereas the levels of adiponectin decrease.
RESUMEN
We aimed to evaluate maternal serum thiol/disulphide homeostasis in pregnancies complicated by fetal distress (FD). A total of 100 patients beyond the 34th week of pregnancy were included in this study, and they were divided into two groups. The study group included 50 patients who had been diagnosed with FD; the control group was composed of 50 patients who had shown no signs of FD and who had undergone an elective (previous) caesarean section (CS). The native thiol, total thiol and native thiol/total thiol (%) concentrations were lower in Group 1 patients than Group 2 patients (p < .001). The disulphide, disulphide/native thiol (%) and disulphide/total thiol (%) concentrations were higher in Group 1 patients than Group 2 patients (p < .001). This study suggests that maternal thiol/disulphide homeostasis is impaired in pregnancies complicated by FD.IMPACT STATEMENTWhat is already known about this subject? Oxidative stress (OS) has previously been investigated in FD. This study reports for the first time a new novel and automatic measurement method.What do the results of this study add? This study shows that the thiol balance shifts in the direction of disulphide in the cases of FD.What are the implications of these findings for clinical practice and further research? Thiol balance can be used for the timely diagnosis of FD.

OBJECTIVES: To investigate maternal serum catalase, myeloperoxidase and ferroxidase levels in pregnant women withHyperemesis Gravidarum and to compare the results with healthy pregnancies. MATERIAL AND METHODS: In this study, 60 female patients admitted to the Health Sciences University, Gazi Yasargil Trainingand Research Hospital, Gynecology and Obstetrics Department were evaluated. The patients were divided into two groups:Group 1 included 30 pregnant women with hyperemesis gravidarum; Group 2 included 30 healthy pregnant women.Pregnancies over 14 weeks were excluded from the study. RESULTS: The laboratory and laboratory characteristics of both groups are shown in Table 1. No significant differences werefound between the groups in terms of the maternal age, gestational age, gravidity, parity, fasting glucose level, and BMI.The maternal blood CAT levels were significantly higher in the HG group (219.6 ± 111.3 kU/L) when compared to the controlgroup (71.5 ± 52.5 kU/L) (p < 0.001). The maternal blood MPO levels were lower in the control group (121.5 ± 36.3 U/L)than in the study group (90.9 ± 56.4 U/L) (p = 0.016). However, the ferroxidase levels were similar between the twogroups. The independent variables BMI, age, parity, gravidity and gestational week effects were adjusted according to thelogistic regression method with groups. Significant differences were observed between the two groups in the levels ofCAT (0.001), MPO (0.005) values. CONCLUSIONS: This study suggests that antioxidants in response to oxidative stress gave different reactions with differentmechanisms; Also, we believe that insufficient food intake suppresses the immune system and this has an important roleon antioxidants.

The aim of the present study was to present a case with secondary hydatid cysts in both uterus and colon. The patient was a 71-year-old female living in Hakkari, Turkey. She was admitted to the Van Yuzuncu Yil University Faculty of Medicine Medical Center with complaints of chronic abdominal and pelvic pain, and swelling in the abdomen. First, the sagittal T2 weighted magnetic rezonance imaging (MR) showed a type-3 cyst hydatid with daughter vesicles located at the posterior of uterus. Later, MR revealed a type-2 cystic lesion with detached membrane adhered to the anterior wall of colon and it was reported to be associated with abdomen. When the previous liver surgery history of the patient was kept in mind, the new finding was suggestive of a secondary cystic hydatid . In conclusion, it is possible to diagnose secondary cystic echinococcosis in patients with a history of primary cyst surgery in liver or any other organ by combining the symptoms and imaging findings.

OBJECTIVE: In this study, we aimed to evaluate the elasticities of fetal placentas with a single umbilical artery using the Virtual Touch Tissue Quantification (VTTQ) technique. MATERIALS AND METHODS: Pregnant women with fetuses with a single umbilical artery (SUA) and pregnant women with fetuses having three vessel cord (3VC) at 18-22 weeks of gestation were enrolled in the research. The placentas were evaluated and divided into three equal parts as the inner 1/3 of the placenta (fetal edge), the outer 1/3 of the placenta (maternal edge) and the central 1/3 of the placenta (central part). Shear-wave velocity (SWV) measurements were used in the elastographic evaluation of placentas by VTTQ. RESULTS: Forty pregnant women were included in the study (n = 20 SUA, n = 20 three vessel cord pregnant women). The placental Acoustic Radiation Force Impulse (VTTQ) of the placenta regarding SWV measurement values of the fetal edge of the placenta in the fetuses with SUA and the control group were 0.876 and 0.957 m/sec, respectively. A significant statistical difference was found between the groups regarding the measurement of the stiffness of fetal placenta (p = 0.021). There was no significant difference between the measured stiffness values of the central or outer region of the placentas. CONCLUSIONS: In this study, we found lower SWV scores for the fetal edge of the placenta with SUA. This finding may reflect tissue elasticity level, and we hope that the use of the VTTQ technique may contribute to predicting the pregnancy-related morbidities of fetuses with SUA in the future.

OBJECTIVES: Ghrelin levels can play an important role in maintaining the energy balance of pregnant women. Therefore, we investigated the relationship between HG and Ghrelin. MATERIAL AND METHODS: 50 female patients admitted to the VAN Yüzüncü Yil University, Gynecology and Obstetrics Department were evaluated. The patients were divided into two groups: Group 1 included 25 pregnant women with HG, Group 2 included 25 healthy pregnant women. RESULTS: The two groups showed similarities in terms of age, gravidity, B-HCG and gestational age. There was no statistically significant difference between the two groups in terms of the Ghrelin levels (p = 0.867). CONCLUSIONS: This study shows that there is no difference between Ghrelin levels and HG during pregnancy. Increased Ghrelin in previous studies was attributed to low oral intake. Another study reported lower Ghrelin levels are not the result of, but are rather the cause of, reduced oral intake during. The balancing of these two conditions does not lead to a change in the level of Ghrelin.

OBJECTIVE: To assess whether the abdominal scar characteristics and closure of the peritoneum were associated with pelvic adhesions. MATERIALS AND METHODS: Patients who had undergone cesarean section between December 2015 and February 2016 were assessed prospectively in terms of age, gravida, body mass index, number of living children, number of cesarean sections, time passed since the last cesarean section, closure status of the peritoneum in the last cesarean section, presence of other diseases, smoking status, location of incision in the abdomen (medial, pfannenstiel) scar dimensions (length, width), scar status with respect to skin (hypertrophic, flat, depressive), scar color [color change/no color change (hyperpigmented/hypopigmented)], adhesion of bowel-omentum-uterus, omentum-anterior abdominal wall, uterus-anterior abdominal wall, uterus-bladder, bladder-anterior abdominal wall, fixed uterus, and uterus-omentum-anterior abdominal wall in abdominal exploration. RESULTS: One hundred five pregnant women who had undergone previous ceserean section surgery by the same physician, were at least in their 30th gestational week, had surgery notes about their previous operation, and had no chronic diseases were included in the study. Age, gravida, body mass index, number of children, number of cesarean sections, time passed since the previous cesarean section, closure/non-closure of peritoneum in the previous cesarean section, and smoking status had no effect on pelvic adhesions. Intraabdominal adhesion was not found to be associated with scar length [odds ratio (OR): 1.54, 95% confidence interval (CI): 1.1-2.2; p=0.02], depressive scar (OR: 9.3, 95% CI: 3.2-27.2; p<0.001), or hypopigmented scar [OR: 0.01, 95% CI: 0.003-0.11; p<0.001]. CONCLUSION: Adhesions following surgical operations are of great importance due to complications for the patient, complications in relaparotomy, and high costs. Depressive and hypopigmented abdominal scars may be associated with pelvic adhesions. We believe that closure or non-closure of the parietal peritoneum is not associated with pelvic adhesions.
RESUMEN
We aimed to evaluate the efficiency of placental elasticity in predicting a placental invasion anomaly with the Virtual Touch Quantification (VTQ) technique. Pregnant women in the third trimester with suspected placental invasion anomaly were enrolled into the research (n = 58). The placenta was evaluated and divided into three equal parts as foetal edge (inner 1/3 of placenta), maternal edge (outer 1/3 of placenta) and the central part (central 1/3 of placenta). Shear wave velocity (SWV) measurements were used in the elastographic evaluation of placentas by VTQ. We performed the measurements at the different regions of placenta for sampling the variety areas of the placenta. Acoustic Radiation Force Impulse (ARFI) Elastography scores were significantly higher in the group in which an invasion was detected during the surgery of patients with preoperative placental invasion suspicion. A significant difference in the measurements of the inner, central and outer third of the placenta between the groups was found (p < .001). In this study, we have shown higher SWV scores of placental measurements of the patients with preoperative suspected anomalies and an invasion detected during their surgery. These findings may reflect an event at the tissue elasticity level and we hope that the use of the VTQ technique may contribute to an early prediction of placental invasions before surgery in the future via new research. Impact statement What is already known on this subject? Placenta invasion anomalies (PIA's) are characterized by haemorrhages which can threat the mother's life. Placental invasion anomalies are among the most important causes of maternal mortality and morbidity. Early diagnosis is very important condition in reducing the mortality and morbidity. Gray scale ultrasonography (US) is mostly used in early diagnosis of PIA's. Acoustic radiation force impulse elastography (ARFI) is a new elastographic ultrasonography technic. We aimed to evaluate a new method in the early diagnosis of PIA's using ARFI technique. There is no study in the diagnosis of PIA's by ARFI in the literature to our knowledge. We think that this original study will contribute to the literature. What do the results of this study add? We showed the accuracy of ARFI in determination of PIA's. ARFI scores were significantly higher in the group in which invasion was detected during surgery of patients with preoperative placental invasion suspicion. What are the implications are of these findings for clinical practice and/or further research? Our findings may reflect an event at the tissue elasticity level and we hope that the use of VTQ technique may contribute to early predict of placental invasions before surgery in the future via new researches. Early diagnosis of placental invasion anomalies may reduce mortality and morbidity.

PURPOSE: To evaluate the maternal thiol/disulfide homeostasis in pregnant women complicated by preterm prelabor rupture of membranes (PPROM) and to compare the results with healthy pregnancies. MATERIALS AND METHODS: This cohort study consisted of thirty-nine pregnancies complicated by PPROM and 44 gestational age-matched healthy pregnancies in the third trimester of gestation. Maternal serum samples were obtained at the day of diagnosis, and thiol/disulfide profiles were measured by using an automated assay method. The patients were followed till delivery, and perinatal outcomes were noted. RESULTS: The maternal native thiol (319.9 ± 30.5 µmol/L versus 305.1 ± 49.2 µmol/L, p: .100), total thiol (379.2 ± 38.8 µmol/L versus 363.6 ± 56.4 µmol/L, p: .142) and disulfide (29.7 ± 11.7 µmol/L versus 29.3 ± 10.1 µmol/L, p: .864) levels were similar between the groups. Maternal disulfide/native thiol, disulfide/total thiol and native thiol/total thiol ratios were similar between the groups (p: .610, p: .565 and .562, respectively). The maternal serum thiol/disulfide profiles were not significantly correlated with maternal serum C-reactive protein, white blood cell count values and ongoing pregnancy outcomes (p > .05). CONCLUSIONS: The current study demonstrated that there was not any disturbance in maternal thiol/disulfide homeostasis in pregnancies complicated by PPROM at the time of initial diagnosis. Follow-up studies with larger sample size are needed to confirm our results.

Objective This study aimed to evaluate the oxidant-antioxidant status of amniotic fluid in pregnant women with foetal congenital malformations of the central nervous system. Methods We studied pregnant women with foetal congenital nervous system anomalies at 16-22 weeks' gestation (n = 36). The control group (n = 30) consisted of pregnant women at the same gestational age who underwent amniocentesis, resulting in a normal karyotype. We analysed glutathione, catalase, and malondialdehyde levels in amniotic fluid. Enzyme activation was measured by spectrophotometry. Results The demographic features of the groups were similar in terms of age, parity, body mass index, and gestational weeks. We detected lower glutathione and catalase levels in the foetal congenital anomaly group than in the control group. We detected higher malondialdehyde levels in the foetal congenital anomaly group than in the control group. Conclusion In the organism, the rate of formation of free radicals and their rate of removal are balanced, and this is called oxidative balance. As long as oxidative stability is achieved, the organism is not affected by free radicals. This fact should be kept in mind to avoid any type of teratogenic agent that could lead to congenital disorders.

AIM: To evaluate the efficacy and safety of levonorgestrel-releasing intrauterine system (LNG-IUS) in the long-term treatment of heavy menstrual blood loss in women unrelated to intrauterine pathology. METHODS: One hundred and six parous women aged 33-48 years with recurrent heavy menstrual bleeding (HMB) participated in this study. The women were followed up for 24 months and were assessed for intensity of bleeding both for pre- and post-insertion periods. An LNG-IUS was inserted in each patient within 7 days of the start of menstrual flow. The women were followed up at 1, 3, 6, 12, 18, and 24 months following the insertion of the intrauterine device. RESULTS: One hundred and two women completed the follow-up period and had a significant reduction in the amount of menstrual blood loss. The LNG-IUS was well tolerated by all women. Pre-treatment of the use of the LNG-IUS, endometrial biopsy patterns for irregular proliferative endometrium and for atypical simple hyperplasia were 34/106 (32.08%) and 61/106 (57.55%) respectively and after treatment no abnormal pathologic findings were determined (p < 0.001). CONCLUSION: Our findings indicate that the LNG-IUS is effective for significantly reducing the amount of menstrual blood loss in women with HMB.

OBJECTIVES: The exact pathogenesis of neural tube defects (NTDs) is poorly understood. We aimed at evaluating maternal anti-oxidant capacity (ceruloplasmin level, myeloperoxidase and catalase activity) in pregnancies complicated by NTDs. MATERIAL AND METHODS: Fifty-four mothers with NTD-affected pregnancies and 61 healthy mothers, matched for gestational age, were recruited. Maternal venous blood samples were obtained after detailed fetal ultrasound examination to measure myeloperoxidase, catalase activity and ceruloplasmin levels. The clinical characteristics of all participants were collected. RESULTS: Maternal blood catalase activity was significantly lower in the study group (117.1 ± 64.8 kU/L) as compared to controls (152.2 ± 110.6 kU/L) (p = 0.044). Maternal blood ceruloplasmin levels were also significantly lower in the study group (180.5 ± 37.7 U/L) as compared to controls (197.9 ± 35.9 U/L) (p = 0.012). Myeloperoxidase activity was similar in both groups (112.6 ± 22.2 U/L vs. 113.6 ± 38.1 U/L) (p = 0.869). CONCLUSIONS: In the present study, maternal blood ceruloplasmin level and catalase activity were found to be lower in NTD-affected pregnancies as compared to healthy controls. Thus, it seems safe to conclude that impaired antioxidant capacity may play a role in the development of NTDs during pregnancy, in addition to the genetic, environmental and metabolic factors.

AIMS: Maternal red blood cell alloimmunization is an important cause of fetal morbidity and mortality in the perinatal period, despite well-organized prophylaxis programs. The objective of the study was to evaluate placental elasticity by using Acoustic Radiation Force Impulse (ARFI) in Rhesus (Rh) alloimmunized pregnant women with hydropic and nonhydropic fetuses and to compare those with healthy pregnant women. MATERIAL AND METHODS: This case-control and descriptive study comprised twenty-eight healthy pregnant women, 14 Rh alloimmunized pregnant women with nonhydropic fetuses, and 16 Rh alloimmunized pregnant women with hydropic fetuses in the third trimester of pregnancy. Placental elasticity measurements were performed by ARFI elastosonography at the day of delivery. The maternal characteristics and neonatal outcomes of the patients were also noted. RESULTS: The highest mean placental ARFI scores were observed in Rh alloimmunized pregnant women with hydropic fetuses (1.13 m/s) (p=0.001). Healthy controls and Rh alloimmunized pregnant women with nonhydropic fetuses had similar mean placenta ARFI scores (0.84 m/s, 0.88 m/s, respectively) (p<0.05). CONCLUSIONS: Based on the present findings, the placenta becomes stiffer in Rh alloimmunized pregnancies complicated with hydrops fetalis. The increased placental ARFI scores may be a supplemental marker for adverse pregnancy outcomes, additional to Doppler evaluation of middle cerebral artery. This data should be confirmed with a large sample size and prospective studies by using serial measurements of ARFI elastosonography in maternal red blood cell alloimmunization.

PURPOSE: Intrahepatic cholestasis of pregnancy (ICP) is a pregnancy-specific liver disorder characterized by maternal pruritus and impaired liver function. The objective of the study was to evaluate maternal liver elasticity by acoustic radiation force impulse (ARFI) elastosonography in ICP and to compare it with that in healthy pregnant women. METHODS: This descriptive, case-control study consisted of 33 women with healthy pregnancies and 22 women with ICP in the third trimester of gestation. Maternal liver elasticity measurements were performed by ARFI elastosonography. The maternal characteristics and perinatal outcomes of the participants were also collected. RESULTS: All maternal liver ARFI elastosonography scores were elevated in women with ICP compared to healthy controls (p = 0.015, p = 0.011, and p = 0.004, respectively). There was a significant positive correlation between maternal liver enzymes and ARFI elastosonography scores (r = 0.404, p = 0.002 and r = 0.389, p = 0.003, respectively). The optimal cut-off point of maternal liver ARFI-mean elastography score to identify the risk of ICP was >1.23 m/s, and the sensitivity and specificity were 68.2 and 69.7%, respectively [area under curve (AUC) 0.731, 95% confidence interval (CI) 0.594-0.869). CONCLUSION: The current study found that maternal liver stiffness measured by ARFI elastosonography was increased in pregnancies complicated with ICP.

OBJECTIVE: To evaluate and describe a surgical approach for uterine preservation and management of postpartum hemorrhage in placenta percreta. METHODS: We analyzed the data of patients who were diagnosed with placenta percreta prenatally and subsequently underwent cesarean section in which local resection technique was used to manage postpartum hemorrhage and uterine preservation at our tertiary care center between 2013 and 2016. The technique includes local resection of placental invasion site and suturing the new uterine edges. RESULTS: The technique of local resection described above was successful in preserving the uterus and stopping the bleeding in 8 of 12 cases. The diagnosis of placenta percreta in all cases was confirmed intraoperatively and postoperatively by histological examinations. Four cases were resorted to hysterectomy. The mean number of transfused erythrocyte suspension was 4.8 ± 2.6. One complication of bladder injury was encountered in which treated conservatively. CONCLUSION: Local resection of percreta site is an effective, safe and fertility preserving approach that can be applied to manage the postpartum hemorrhage and preservation of uterus in patients with placenta percreta.

PURPOSE: To compare maternal liver elasticity scores by Acoustic Radiation Force Impulse (ARFI) elastosonography in healthy and preeclamptic pregnancies and its association with the severity of the disease. MATERIALS AND METHODS: Forty-two healthy, 33 mild, 33 severe preeclamptic and 28 pregnant women with Hemolysis, Elevated Liver enzymes and Low Platelets (HELLP) syndrome were included into the study. Maternal liver elasticity was measured by ARFI elastosonography at the first day of puerperium. The maternal and neonatal outcomes of the patients were retrieved from the medical records. RESULTS: The ARFI-Mean liver elastosonography scores of controls and mild preeclamptic women were lower than severe preeclamptic and HELLP syndrome women (p: 0.001). The mean ARFI elastosonography score >1.22 m/s indicated the effect of severe preeclampsia on maternal liver elasticity with 72.7% sensitivity and 74.7% specificity (Area under curve [AUC], 0.835, 95% confidence interval [CI], 0.757-0.913). The mean ARFI elastosonography score >1.31 m/s indicated the effect of HELLP syndrome on maternal liver elasticity with 78.6% sensitivity and 75.9% specificity (AUC, 0.794, 95% CI, 0.695-0.892). CONCLUSIONS: The maternal liver becomes stiffer in severe preeclampsia and HELLP syndrome measured by ARFI elastosonography. The increased maternal liver ARFI scores may alert the obstetrician about the possible maternal puerperal morbidity.
