RESUMEN
Background: Hypertension complicates 5-10% of pregnancies and is a common cause of perinatal death. The perinatal mortality is estimated to be 3 to 5 times higher in hypertensive women compared to those without hypertension. Methods: A hypertensive mother either with a stillbirth or if baby died within 7 days of life was included as a case. Once a case was recognized, the next two consecutive hypertensive mothers who delivered a live baby, who survived up to 7 days of life, were taken as controls. Fetuses with congenital malformations incompatible with life and multiple pregnancies were excluded from the study. One hundred and twelve women in cases and 224 women in controls were studied. Results: Among 112 cases of perinatal death, 70% had died in utero before labor. Among the 33 fetuses alive, 50% were born still after labor and 50% died within 7 days of birth. We found that early onset hypertension (< 34 weeks) (p-< 0.001 (Chi2-23.819)), gestational age at termination of 28-32 weeks (OR 2.76), value of serum creatinine > 1.1 mg/dl (OR 10.1), abruption (OR 6.2) and birth weight < 1.5 kg was significantly associated with perinatal mortality (p-0.007, OR 5.7). Abnormal Doppler findings was a predictor of perinatal deaths. Conclusion: Severely growth retarded fetuses in association with early onset severe preeclampsia are likely to die in utero and need vigilant monitoring antenatally. Abnormal umbilical artery Dopplers predict perinatal mortality. Caesarean section at the gestational age of ≥ 32 weeks and an estimated fetal weight of ≥ 1.2 kg in our hospital resulted in favorable outcome.
RESUMEN
PURPOSE: Traditional microscopy-based methods may provide inaccurate estimates of Soil transmitted helminth (STH) infections in mild intensity of infection. Therefore, we aimed to determine the prevalence of STH infections using molecular diagnostic methods and compare the diagnostic performance of microscopy with polymerase chain reaction (PCR) in stool samples collected from pregnant women in primary care settings in Puducherry, India. METHODOLOGY: A singleplex PCR assay was developed to detect three species of STHs, namely Ascaris lumbricoides, Necator americanus, and Ancylostoma duodenale, by targeting the internal transcribed spacer regions (ITS1 and ITS2) of 5.8S rRNA. The PCR generated 420, 662, and 515 base pairs of DNA for the respective organisms. In addition to singleplex PCR, wet and concentration microscopy techniques were used. The results were expressed as percentages with 95% confidence intervals, and the diagnostic performance of microscopy was compared with PCR in terms of sensitivity, specificity, and positive, negative predictive values and kappa statistics. RESULTS: Among the 650 pregnant women included, 48.8% were aged 25 years or less, 59% were primigravida, and half were from rural areas. The overall prevalence of any STH infection was higher in PCR compared to microscopy (8.9% vs. 7.2%). The prevalence of Ascaris lumbricoides was higher by microscopy (5.4% vs 2.6%), while the prevalence of Necator americanus was higher by PCR (6.3%) than by microscopy (1.8%). No species of Ancylostoma duodenale was detected. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of microscopy for detecting any STH infection was 22.4%, 94.3%, 27.7%, and 92.5%, respectively. The agreement between microscopy and PCR for the identification is as follows: for any STH infection, k â= â0.12, Ascaris k â= â0.16, and Necator k â= â0.20, respectively. CONCLUSION: The prevalence of any STH infection identified by PCR was higher than microscopy, and the agreement between the two methods was poor.

Identifying preeclamptic women with an increased risk of severe maternal complications can aid in timely interventions to optimize pregnancy outcomes. Newer biomarkers such as Decorin and markers of endo glycocalyx disruption were assessed in earlier studies for its role in predicting preeclampsia, but their role in identifying those with adverse maternal outcomes is limited. This study aimed to evaluate the association of these biomarkers with adverse maternal outcomes in women with severe pre-eclampsia. Markers of glycocalyx disruption may be further explored for their role along with clinical features and other biomarkers in identifying women at higher risk of maternal complications.

Background: The optimum time of labour induction among women with a previous caesarean without any pregnancy complication and eligible and willing for vaginal delivery is not specified. This study compares the vaginal birth rates between induction at 40 weeks and expectant management till 41 weeks. Method: We conducted this parallel design nonblinded, randomized controlled trial in a tertiary care teaching institution in South India on women with a previous lower segment caesarean section eligible for a trial of labour with singleton foetus without any pregnancy complication at recruitment. We screened 1886 women. Sixty women underwent block (of 6 each) randomization into two groups of thirty each at 40 weeks. We induced the women in the intervention group at 40 weeks with oxytocin or a single 24-hour application of a Foley catheter followed by oxytocin infusion and amniotomy. The expectant group underwent maternal and foetal surveillance and induction at 41 weeks with the same protocol if not delivered by then. We compared the primary outcome of the proportion of vaginal birth rate with a chi-square test. Result: Data from all sixty women were analyzed. Twenty (66.67%) in the induction compared to ten (33.33%) in the expectant group delivered vaginally. This difference was significant (RR 2.0, 95% CI: 1.13-3.52; P = 0.016). One woman in the expectant group had scar dehiscence. Conclusion: Among women with a previous caesarean scar, labour induction at 40 weeks has a significantly higher vaginal birth rate than those managed expectantly till 41 weeks. More extensive trials are feasible and recommended. Trial Registry. The trial was prospectively registered with the clinical trial registry of India. This trial is registered with CTRI/2018/09/015719 (date of registration 14th September 2018).

Background & objectives: Postpartum intrauterine contraceptive device (PPIUCD) is well accepted and recommended for contraception. However, anxiety at the time of delivery may restrict the acceptance of a PPIUCD for its immediate insertion. So far there is limited evidence to conclude anything concrete on the association between the expulsion rates and the timing of insertion following a vaginal delivery. Thus, this study was undertaken to compare the expulsion rates in immediate and early insertions and their safety and complications. Methods: This prospective comparative study was carried out over 17 months on women delivering vaginally in a tertiary care teaching hospital in South India. A copper device (CuT380A) was inserted using Kelly's placental forceps either within 10 min of placental delivery (immediate group, n=160) or between 10 min upto 48 h postpartum (early group, n=160). Ultrasound was done before discharge from the hospital. The expulsion rates and any other complications at six-week and three-month follow up were studied. Chi-square test was used to compare the difference in expulsion rates. Results: The expulsion rate was five per cent in the immediate compared to 3.7 per cent in the early group (no significant difference). In ten cases, the device was found to be in the lower uterus upon ultrasound before discharge. These were repositioned. There was no case with perforation, irregular bleeding or infection up to the three-month follow up. Higher age, higher parity, lack of satisfaction and motivation to continue were predictors of expulsion. Interpretation & conclusions: In the present study PPIUCD was found to be safe with overall expulsion in 4.3 per cent. It was marginally, though not significantly, higher in the immediate group.

Introduction: The incidence of neonatal mortality has declined over the past few decades, but it remains a major concern. Identifying risk factors associated with adverse outcomes may help prevent and manage neonatal morbidity and mortality. The study aimed to explore the associated antenatal risk factors among pregnant women delivering in a tertiary care hospital in South India with adverse neonatal outcomes. Material and Methods: This was a hospital-based, matched case-control study among pregnant women belonging to Puducherry and admitted for delivery. Cases were pregnant women who gave birth to adverse neonatal outcomes, while controls were pregnant women who gave birth to alive and healthy babies. Data was collected from various sources, primarily from medical records, and triangulated. Results: Adverse neonatal outcomes were ten times more if pregnant women had placental complications and seven times more for intrauterine growth restriction noted during pregnancy. Pregnant women referred from peripheral care centers had 1.6 times more risk of adverse neonatal outcomes. Prior hospital admission during the present pregnancy had a protective effect in the final adjusted analysis. Conclusion: Risk factors should be routinely monitored in all health centers. Women with high-risk pregnancies should be identified earlier, and appropriate care should be provided.
RESUMEN
Community-based studies from India on prevalence of soil-transmitted helminth (STH) infections have reported estimates as high as 50% in children. However, prevalence estimates during pregnancy in India are lacking. We aimed to describe the burden, associated factors of STH and cure rate after deworming in primary care settings. Pregnant women were recruited from four urban and five rural centers in Puducherry, South India, from December 2019 to April 2022. One stool sample was collected from each participant before deworming and one repeat sample was collected from STH positive woman after three weeks of deworming. The samples were processed with saline; iodine wet mount, and microscopic concentration techniques. Cure rate (CR) was assessed using Kato-Katz thick smear. Of 650 women included, 49 (7.5%, 95% CI 5.6-9.8) had one of the STH infections; the prevalence of Ascaris lumbricoides, hookworm and Strongyloides was 5.4%, 1.8% and 0.3%, respectively. The prevalence of any STH was higher among ages 26-30 years (9.1%), working women (8.3%), multigravida (8.3%), urban setting (8.3%), those who did not wash their hands before food (9%) and anemic women (8.9%), compared to their counterparts, but not statistically significant. The CR for hookworm was 100% and Ascaris lumbricoides was 88.6%. To conclude, the prevalence of STH was low among pregnant women compared to school aged children. Continued deworming activities along with improved sanitation could further reduce the burden.
RESUMEN
Background: The purpose of antenatal care (ANC) is to identify 'at-risk' pregnant women, to provide quality care for all, and maximize the allocation of resources for those who need them the most. To address the synergistic effect of risk factors, clinicians across the globe developed antenatal scoring systems. Objective: This review aims to investigate various antenatal risk scoring systems developed and used in India to predict adverse neonatal outcome. Methods: We reviewed articles published between January 2000 and April 2020, which have either developed a scoring system or used a scoring system, among the Indian population. This systematic review is reported based on Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. Prediction model study Risk Of Bias Assessment Tool (PROBAST) was employed for the assessment of the quality of included studies. Data sources such as Embase, MEDLINE/Pubmed, APA PsycExtra, PsycINFO, CINHAL Plus, Cochrane Library, IndMED, LILACS, Scopus, WHO Reproductive Health Library and Web of science were searched. Results: An initial search retrieved a total of 6246 articles. This systematic review identified six studies, of which one study developed an antenatal scoring system and the other five studies used two antenatal systems for predicting adverse neonatal outcome. The study which developed a risk scoring system had a high risk of bias (ROB) and concern for applicability. The overall sensitivity of the antenatal scoring system was high (77.4%), but the specificity was low (45%). Similarly, the positive predictive value is low (15.3%), and the negative predictive value is high (94.2%). A meta-analysis was not conducted due to the heterogeneity of the studies and insufficient data. Conclusions: There is a need for a systematically developed antenatal scoring system for India. Such scoring systems can be promising in public health, proposing a paradigm shift in the implementation of effective mother and child health programmes locally as well as nationally.

RESUMEN
BACKGROUND: Induction of labor in women with previous cesarean section is associated by the fear of scar rupture, resulting in high rates of repeat scheduled cesarean section. Mechanical methods are being advocated as a safe method. We present our experience of vaginal birth rates and safety profile with single-balloon Foley's catheter for induction of labor in women with previous one cesarean section. METHODS: We studied 96 women admitted in Women and Children Hospital JIPMER, India, with a previous cesarean section at term having unfavorable cervix and undergoing induction of labor. Foley's catheter inflated to 60 ml was used for cervical ripening for 24 h followed by strict oxytocin infusion protocol. RESULTS: The mean Bishop score before induction of labor was 3.3 ± 0.88. Ripening with Foley's catheter resulted in mean improvement in the Bishop score by 2.56 ± 0.67. Forty-seven percent women spontaneously expelled the Foley's catheter, and 53.1% achieved contractions spontaneously. The successful vaginal birth rate was 40%. Emergency caesarean section was more likely in women with poor post ripening Bishop score, meconium stained liquor and abnormal fetal heart rate pattern during labour. There was one scar dehiscence, one neonate with low Apgar score. There was no rupture uterus. CONCLUSION: Induction of labor with Foley's catheter resulted in a 40% successful vaginal birth rate and was found to be safe with only one scar dehiscence and no perinatal or maternal mortality. There was no perinatal or maternal mortality.
RESUMEN
BACKGROUND: Pregnancy is a metabolic state which demands increased iron bioavailability. While in preeclampsia, due to the placental vascular events there is an iron surplus environment along with inflammation and placental hypoxia. Routinely in India iron is supplemented to all pregnant women irrespective of their general physical condition. Hepcidin a regulator of iron metabolism protects the cells from iron mediated cytotoxicity. OBJECTIVE: To find out whether hepcidin gets induced as a protective mechanism in preeclampsia patients in order to combat the environment of iron overload, oxidative stress, and endothelial dysfunction. METHODS: A cross-sectional study with follow up was carried out in a South Indian Tamil population. Forty healthy pregnant women and forty preeclampsia patients in the gestational age 32 ± 4 weeks were recruited (n = 80). Biochemical analysis to assess the serum levels of the following were carried out (1) indices of iron homeostasis - serum iron, ferritin, transferrin, hepcidin, (2) endothelial dysfunction -serum assymetric dimethyl arginine (ADMA) (3) oxidative stress - Malon di aldehyde (MDA) and ferric reducing ability of plasma (FRAP). Kolmogorov-Smirnov test, Mann-Whitney U test, Spearman's correlation, linear regression and ROCAUC analysis were performed to understand their relationship with each other. RESULTS: Levels of serum iron, ferritin, transferrin saturation, hepcidin, and MDA/FRAP ratio were elevated significantly in preeclampsia patients compared to controls, while serum transferrin levels were significantly decreased in them. Hepcidin levels showed a significant positive correlation with serum ADMA, and MDA/FRAP. Serum hepcidin, transferrin saturationand MDA/FRAP ratio is useful in differentiating pre-eclampsia patients from healthy pregnant women. CONCLUSION: Iron supplementation in preeclampsia patients might have led to a state of iron overload, which might have caused oxidative stress and endothelial dysfunction in preeclampsia patients. The rise in hepcidin levels in this scenario may be viewed as a protective mechanism to combat the iron overload mediated cytotoxicity.

Malakoplakia is a chronic xanthogranulomatous condition that affects the genitourinary tract reported earlier as urinary granulomas and pelvic masses. We report a different clinical manifestation of malakoplakia presenting as postmenopausal pyometra. A 64-year-old postmenopausal female presented with foul-smelling vaginal discharge with a past history of induced abortion, followed by dilatation and evacuation. On examination, abdomen was soft, vaginal examination revealed pus discharge, parous size uterus with free fornices, and pap smear ruled out malignancy. Ultrasonography revealed linear, echogenic structures in the endometrial cavity suspicious of bony spicules with fluid around. Hysteroscopy revealed congested endometrium with multiple pieces of shredded bone-like structures that were removed followed by curettage. Histopathological examination was suggestive of malakoplakia with osseous metaplasia. Retained bony spicules can cause chronic granulomatous inflammation that may become symptomatic postmenopause due to absent cyclical shedding. This is the first reported case of malakoplakia of uterus following retained bony spicules.
RESUMEN
Mitrofanoff operation or vesico-appendicostmy is a continent conduit operation performed for intractable incontinence. The long-term complications reported in the literature are related to the stoma. Pelvic organ prolapse among women who have undergone this surgery is not reported earlier. A woman of 27 years of age presented with uterovaginal prolapse. She had sustained bladder neck transection following a road traffic accident at 16 years of age. The same was primarily repaired but incontinence had remained. Many standard operations for incontinence were performed. Finally, Mitrofanoff operation was carried out 9 years back because of persisting intractable incontinence. She got married and had two uneventful vaginal deliveries 5 and 2 years back. There was supravaginal elongation of the cervix with a rectocele. After counseling Fothergills operation with laparoscopic ligation was performed. The challenges and details of the management of the case are highlighted.
RESUMEN
BACKGROUND: As a mitigation measure for COVID-19 pandemic, lockdown was implemented in India for a period of 2 months (24 March-31 May 2020). Disruption in antenatal care (ANC) provisions during lockdown is expected due to diversion of public health facilities on pandemic. OBJECTIVE: To assess the proportion of pregnant women who had not completed the ideal number of antenatal visits, availability of iron-folic acid (IFA) supplements and challenges in availing health services during the period of lockdown. METHODS: A concurrent mixed-methods study was conducted among pregnant women in Puducherry, India. Information on obstetric characteristics and details regarding antenatal visits were collected through telephonic interviews. In-depth interviews were conducted to understand the perceived challenges in availing health services during the lockdown period. RESULTS: Out of 150 pregnant women, 62 [41.3%; 95% confidence interval (CI) 33.6-49.3] did not complete the ideal number of visits and 61 (40.7%, 95% CI 32.7-49.0) developed health problems. Out of 44 women who received medical care for health problems, 11 (25%) used teleconsultation. Of all the women, 13 (8.7%, 95% CI 4.9-14.0) had not taken the IFA supplements as prescribed by the health provider. Economic hardship, restricted mobility, lack of information about the health system changes and psychological stress due to the fear of COVID were the challenges in accessing care. CONCLUSIONS: Two out of five pregnant women did not complete the ideal number of visits and developed health problems during the lockdown period.

BACKGROUND: Childbirth experience is unique to every woman. Negative experience is detrimental to both mother and child. This study was undertaken to understand the positive and negative experience and felt need of women undergoing labor and the factors affecting them. METHODOLOGY: This cross-sectional descriptive quantitative study was conducted among women who delivered in JIPMER and consented to participate through a questionnaire that captured four areas of childbirth experience. The study was carried out before the LaQshya guidelines were implemented. RESULTS: Three hundred and seventy women completed the study. The mean age of women in this study was 24.5 years and 60% were primipara. Five women (1.3%) experienced physical abuse. Another 47 (12.7%) experienced disrespect in the form of scolding/insult/discrimination or nonconsented care. Three-fourths of the women wanted a relative (majority preferred their mother) with them, and 54% wanted a prayer hall in the labor room. On univariate analysis, no significant determinant was found for negative experience constituting disrespect and abuse. Complete pain relief as a need was found to be significantly higher (X2 = 11.0783, p < 0.004) in women of lower parity. The women educated beyond scholastic level felt that information given about delivery is inadequate when compared to participants who were illiterate or had primary education only. CONCLUSIONS: In our hospital 12.7% women undergoing labor experienced disrespectful behavior and 1.3% experienced physical abuse. Need for prayer hall, complete pain relief and presence of relative was felt by more than half of the participants. We did not find any specific factor influencing the negative experience.
RESUMEN
BACKGROUND: The literature on neonatal outcomes in preterm twins delivered before 34 weeks but within and after 14 days of a single initial steroid course is limited. MATERIAL AND METHODS: This bidirectional (226 prospective and 42 retrospectives) cohort study was performed at a tertiary care teaching hospital in South India. We compared the respiratory distress syndrome and neonatal death amongst preterm twins from 28 to 34 weeks born < 14 days (Group A, n=268) and after 14 days (Group B, n=268) of completion of a single course of antenatal steroids. We used multivariable regression analysis (log-binomial model) to adjust for confounding variables. We generated a propensity-matched score with probit regression to analyse outcomes (respiratory distress and neonatal deaths). RESULTS: The two groups had significant differences in the distribution of birthweight, gestation period and mode of delivery. On adjusted analysis, the period of gestation below 33 weeks and weight below 1.5 kg had the maximum influence on respiratory and other morbidities, and weight less than 1 kg on neonatal death. [adjusted relative risk (ARR) 26.06, (95%CI=2.37-285.5), p=0.008]. On propensity scoring after matching all these variables, we found an [ARR of 2.0 (95% CI: 1.03-3.88), P=0.017] for neonatal death after 14 days of steroid injection. The ARR for respiratory distress syndrome was 1.13 in those born after 14 days of steroids, though it did not reach statistical significance. CONCLUSION: On propensity scoring, the steroid-delivery interval more than 14 days was associated with a significantly increased risk (ARR of 2) of neonatal death.

BACKGROUND: Low birth weight and prematurity are the major contributors to neonatal mortality and morbidity. Preeclampsia which is associated with both maternal and fetal mortality and morbidity is a major contributor to such poor fetal outcomes. Hepcidin an acute phase peptide hormone gets elevated in conditions of iron overload, inflammation, infections, and cytotoxicity. Hepcidin levels can get elevated in pregnancies with such pathologies which invariably will be having a poor fetal outcome. OBJECTIVE: To study the role of hepcidin as a diagnostic marker in predicting a poor fetal outcome. MATERIALS AND METHODS: A cross-sectional study with follow up was carried out in a South Indian Tamil population. Forty healthy pregnant women and forty preeclampsia patients were recruited between the gestational age of 34 ± 4 weeks and followed up till delivery. Serum levels of hepcidin were analyzed for all the participants and comparisons were done between preeclampsia and healthy pregnancies as well as between pregnancies with good and poor fetal outcomes. Fetal outcome variables such as birth weight, gestational age at the time of delivery and NICU admission status of the newborn were collected during the follow-up period. ROC curves were constructed to determine the ability of maternal serum hepcidin levels in predicting poor fetal outcomes with good sensitivity, specificity and likelihood ratios. RESULTS: Maternal hepcidin levels were found to be significantly elevated in preeclampsia patients (p < .001) as well as in mothers with the poor fetal outcome (p < .001). On ROC curve analysis, AUC were 0.686, 0.788, 0.749 and LR + were 2.18, 2.44, 2.14, respectively for predicting low birth weight, preterm delivery and NICU admission status of the newborn. Hepcidin was able to predict the overall poor fetal outcome in our preeclampsia patients above a cut off level of 615 pg/ml. CONCLUSION: Above a cut off level of 615 pg/ml and at the gestational age of 34 ± 4 weeks, maternal hepcidin levels were able to predict poor fetal outcomes such as low birth weight, preterm delivery, and NICU admission.

INTRODUCTION: Gestational diabetes mellitus (GDM) exhibit altered placental lipid metabolism. The molecular basis of this altered metabolism is not clear. Altered placental expression of proteins of lipogenesis and fatty acid oxidation may be involved in the placental accumulation of triacylglycerols (TG). The present study was aimed at investigating the differential expressions of placental proteins related to lipid metabolism among GDM women in comparison with control pregnant women (CPW) and to correlate them with maternal and fetal lipid parameters as well as altered fetal growth. MATERIALS AND METHODS: Maternal blood, cord blood, and placental samples were collected from GDM and CPW. The biochemical parameters, glucose, lipid profile and free fatty acids (FFA) were measured. The placental TG content was measured. Differential placental expressions of proteins; phosphatidylinositol-3-kinase (PI3K) p85α, PI3K p110α,liver X receptor alpha (LXRα), sterol regulatory element binding protein1(SREBP1), fatty acid synthase (FAS), stearyl CoA desaturase1 (SCD1), lipoprotein lipase (LPL),Peroxisome proliferator-activated receptor (PPAR)α and PPARγ were analysed by western blotting and immunohistochemistry. RESULTS: Placental protein expressions of PI3K p110α, LXRα, FAS, SCD1, and LPL were found to be significantly higher, whereas PPARα and PPARγ were lower in GDM women compared with CPW. The placental TG content and cord plasma FFA were increased in GDM women compared with CPW. The placental TG content positively correlated with Ponderal index of GDM new-borns. CONCLUSION: Differential expressions of placental proteins related to lipid metabolism in GDM might have led to placental TG accumulation. This might have contributed to the fetal overgrowth in GDM.

INTRODUCTION: The placental glucose transporter - 1 (GLUT-1) is involved in the transplacental glucose transport to the fetus. GLUT-1 expressions are increased in diabetic pregnancies and associated with altered fetal growth. However, the factors regulating the GLUT-1 expressions are largely unknown. We hypothesised that maternal adipokines and insulin-like growth factor-1 (IGF1) modulate the placental expressions of GLUT-1 through the activation of insulin/IGF-1 signalling which may contribute to a fetal overgrowth in GDM. METHODS: Maternal blood, cord blood and placental samples were collected from GDM and control pregnant women (CPW). The biochemical parameters, IGF1, adipokines, and high sensitive C- reactive protein were measured. We analysed the placental expressions of GLUT-1 and proteins related to insulin/IGF-1 signalling - insulin receptor -ß, insulin receptor substrate - 1, phosphatidylinositol-3-kinase p110α, phospho Akt-1, phospho extracellular signal-regulated kinase 1/2, and nuclear factor-κB p65 in GDM and CPW. RESULTS: Increased maternal IGF-1 and decreased adiponectin levels were found in the GDM women. Maternal IGF-1 levels were positively correlated, whereas adiponectin levels were negatively correlated with the birth weight of GDM newborns. Increased phosphorylation of Akt and ERK 1/2 was found in the placenta of GDM women. Placental expressions of GLUT-1 were significantly higher in the GDM women and positively correlated to the maternal IGF-1 levels in the GDM group. DISCUSSION: Decreased maternal adiponectin and increased IGF-1 levels might have caused increased GLUT-1 expression via the increased activation of insulin/IGF-1 signalling in the placenta of GDM women which might have influenced the fetal growth.

Pregnant women presenting with isolated cranial palsies are uncommon. Isolated sixth nerve (abducens nerve) palsy can occur for a variety of reasons and neuroimaging is often performed to identify an underlying cause. We report a case of a woman in her third pregnancy with preeclampsia who presented with an isolated sixth nerve palsy. The diagnosis of aseptic cavernous sinus thrombosis was made and she subsequently made a full recovery.
