RESUMEN
OBJECTIVE: To compare the mRNA expression of placental iron transporters (TfR-1 and FPN), markers of placental vascularization (VEGF and sFLT1) and marker of structural integrity (LMN-A) in term women with and without iron deficiency anemia. MATERIALS AND METHODS: A total of 30 pregnant women were enrolled; 15 cases of iron deficiency anemia (Hb 7-10.9 gm/dL) and 15 gestational age matched healthy controls (Hb ≥ 11 gm/dL). Peripheral venous blood was collected for assessment of hemoglobin levels and serum iron profile. Placental tissue was used for assessing the mRNA expression of TfR-1, FPN, VEGF, sFLT-1 and LMN-A via real time PCR. RESULTS: Placental expression of TfR-1, VEGF and LMN-A was increased in pregnant women with anemia compared to healthy pregnant controls. Placental expression of sFLT-1 was decreased in pregnant women with anemia compared to healthy pregnant controls. There was no change in the placental expression of FPN. CONCLUSION: The increased expression of TfR-1, VEGF and LMN-A in cases of iron deficiency anemia are most likely to be compensatory in nature to help maintain adequate fetal iron delivery. WHAT DOES THIS STUDY ADDS TO THE CLINICAL WORK: Compensatory changes in the placenta aimed at buffering transport of iron to the fetus are seen in pregnant women with anemia compared to healthy pregnant controls.

OBJECTIVE: We compared efficacy of weight-based (0.4 IU/kg/h) versus fixed-dose (34 IU/h) oxytocin infusion during cesarean section. METHODS: The oxytocin infusion in either group (n = 32 each) was initiated upon cord clamping. Primary outcome measure was adequacy of uterine tone at 4 min after initiating oxytocin infusion. Oxytocin associated side effects were also observed. RESULTS: Significantly less oxytocin was used with the weight-based versus fixed-dose regimen (16.3 [11.2-22.4] IU vs 20.4 [15.8-26.9] IU; P = 0.036). Incidence of adequate uterine tone was clinically greater but not significantly different with the weight-based versus fixed-dose regimen (81.3% vs 71.9%; P = 0.376). The weight-based regimen was associated with clinically lesser, although not statistically significant need for rescue oxytocin (25% vs 46.9%; P = 0.068) and additional uterotonic (9.4% vs 15.6%; P = 0.708); as well as oxytocin associated side effects (hypotension [34.4% vs 46.9%; P = 0.309], nausea/vomiting [18.8% vs 40.6%; P = 0.055], and ST-T changes [0% vs 3.1%; P = 1.000]). CONCLUSION: Weight-based oxytocin was not significantly different from the fixed-dose regimen in terms of uterotonic efficacy or associated side-effects, despite significantly lower doses being used. Use of weight-based oxytocin infusion (0.4 IU/kg/h) can be considered in clinical practice. TRIAL REGISTRATION: Clinical Trial Registry of India (ctri.nic.in, number. CTRI/2021/01/030642).

OBJECTIVE: The aim of the study was to explore the utility of fluorescein sodium (FNa) as a contrast agent for colposcopy to detect premalignant and malignant lesions of cervix. The primary objective was to determine and compare the percentage detection of premalignant and malignant lesions of FNa and acetic acid (AA) positive areas. METHODS: This study included 120 screen positive women who underwent colposcopy using both 3% AA and FNa (0.06%). Observations for FNa staining were made under blue filter and directed biopsies were taken from acetowhite and fluorescent green areas. Benign lesions were considered as disease-negative and low grade squamous intraepithelial lesions (LSIL), high grade SIL (HSIL), and invasive cancer were considered as disease-positive. Correlation between histopathology and FNa and AA was determined by Kappa statistics. RESULTS: The mean age was 39.59 ± 10.73 years and median parity was 2. Out of 120 patients, 57 had benign lesions, 18 had LSIL, 33 had HSIL and 12 had invasive carcinomas. Sensitivity was 98.41% versus 64.91% respectively and specificity was 85.71% versus 35.09% respectively with FNa and AA. Diagnostic accuracy of FNa and AA was 82.50% versus 61.60%. There was good agreement between FNa staining and final histopathology and fair agreement between AA application and HPE (κ = 0.643 vs 0.213, P < 0.001). CONCLUSION: Using FNa as a contrast agent during colposcopy results in greater accuracy for detection of premalignant and malignant lesions of the cervix as compared to AA.

Medical devices and materials commonly used in management of common gynecological conditions or during surgical procedures may present with acute or chronic complications due to incorrect application, improper use and lack of follow up. We present two interesting cases highlighting this problem. A strong index of suspicion is very crucial in early diagnosis and successful management.
RESUMEN
OBJECTIVE: To compare the feasibility of vagino-hysteroscopy using alginate gel Interface (VAGI) with conventional vaginoscopic hysteroscopy (CVH). METHODS: Thirty women undergoing diagnostic vagino-hysteroscopy were randomly allocated into Group I (VAGI): Alginate occluder was used at introitus to facilitate hydrodistension during hysteroscopy; or Group II: Underwent no-touch hysteroscopy. Primary outcome was feasibility, defined as successful visualization of uterine cavity. Secondary outcomes included operative time, hydrostatic pressures for optimum visualization, pain experienced by patient on visual analog scale, maneuverability and surgeon satisfaction. Data analysis was performed using χ2 and Fisher exact tests for qualitative variables and Student t test for quantitative variables. RESULTS: VAGI was significantly better than CVH (80% vs. 33.3%; relative risk 8, P = 0.025). With VAGI, optimum visualization was achieved at significantly lower pressures at all levels (vagina, P = 0.034; cervix, P = 0.01; uterus, P < 0.001), in less time (P = 0.007), and using less irrigation fluid (P < 0.001). Surgeon satisfaction was significantly higher for VAGI (P = 0.009). Subgroup analysis showed higher likelihood of success of VAGI in women who were premenopausal (P = 0.015), younger than 45 years (P = 0.024), and had a history of vaginal birth (P = 0.03). CONCLUSIONS: VAGI is quicker to perform and provides optimum visualization at much lower pressures than CVH. Use of alginate is patient friendly and yields higher surgeon satisfaction rate.

Postpartum haemorrhage remains a significant cause of maternal morbidity and mortality with the commonest reason being uterine atony. For prevention of uterine atony during caesarean delivery, oxytocin is advocated as a first line drug. There is however no published data regarding utility of a weight-based oxytocin infusion. The present study evaluated dose-response relationship for oxytocin infusion when used as weight-based regimen. A total of 55 non-labouring patients without risk factors for uterine atony and scheduled for caesarean delivery under spinal anaesthesia were enrolled. Randomization was done to receive oxytocin infusion in a dose of 0.1, 0.15, 0.2, 0.25 or 0.3 IU kg-1 h-1 (n = 11 each), initiated at the time of cord clamping and continued until the end of surgery. Successful outcome was defined as attaining an adequate uterine response at 4 min of initiation of infusion and maintained till end of surgery. Oxytocin associated hypotension, tachycardia, ST-T changes, nausea/vomiting, flushing and chest pain were also observed. A significant linear trend for adequate intraoperative uterine tone was seen with increasing dose of weight-based oxytocin infusion (P < 0.001). The effective dose in 90% population (ED90) was 0.29 IU kg-1 h-1 (95% CI = 0.25-0.42). Amongst the oxytocin associated side effects, a significant linear trend was seen between increasing dose of oxytocin infusion and hypotension as well as nausea/vomiting (p = 0.016 and 0.023 respectively). Thus, oxytocin infusion during caesarean delivery may be used as per the patient's body weight.

BACKGROUND: Term small for gestational age (SGA) babies are at risk for developing iron deficiency anemia. The association between maternal and infant iron stores is not clear. OBJECTIVE: To assess proportion of term SGA neonates developing iron deficiency anemia by 10 weeks of age, and measure correlation between iron profile and hepcidin of babies at birth and at 10 weeks of age with maternal iron profile. DESIGN: Prospective cohort study conducted from November, 2018 to April, 2020. PARTICIPANTS: 120 term SGA babies and their mothers. INTERVENTION: Hemogram, iron profile and serum hepcidin (every fourth case) estimated in mother, cord blood and baby at 10 weeks. Babies developing anemia at 6 weeks detected by hemogram and ferritin were started on iron supplementation and excluded from the study. OUTCOME: Proportion of babies developing iron deficiency anemia at 10 weeks of age. RESULTS: 35 (29.2%) of 120 term SGA babies developed anemia (hemoglobin <9 g/dL) at 6 weeks. Proportion of infants who developed iron deficiency anemia (hemoglobin <9 g/dL and serum ferritin <40 µ/dL) at 6 and 10 weeks of age was 14.2% and 23.3%, respectively. No significant correlation was found bet-ween hemoglobin, iron and hepcidin of the baby in cord blood and at 10 weeks of age with that of mothers. Serum hepcidin in babies at birth (137.5 ng/mL) were higher than maternal values (128 ng/mL). CONCLUSION: A significant proportion of term SGA infants deve-loped anemia during early infancy, irrespective of maternal iron status.

Objectives: DNA methylation of paired box-1 (PAX-1) gene has been shown to be a potential biomarker for the detection of high-grade cervical intra-epithelial neoplasia (CIN) and invasive cervical cancer. The objective of this pilot study was to quantify and compare methylation percentage of PAX1 gene in benign cervical lesion, pre-invasive and invasive cervical cancer. Methods: A total of 200 screen positive women (VIA, VILI and Pap test) underwent colposcopy. Cervical scrapes taken were taken and stored for DNA analysis and PAX 1 methylation status. Women with Swede score of 5 or more (n = 98) were biopsied. Cervical scrapes and biopsy were taken from women with obvious cervical growth (n = 14), without prior colposcopy. Sixty women were recruited to the study and allocated into three groups on the basis of histopathology, i.e., benign cervix (Group 1; n = 20), CIN 2/3 (Group 2; n = 20) and invasive cervical carcinoma (Group; n = 20). PAX 1 methylation percentage was calculated from the DNA extracted from the cervical scrapes of the women recruited. Results: The mean PAX1 methylation percentage in benign lesions, CIN 2/3 and invasive cancer was 9.58% (SD ± 2.37%), 18.21% (SD ± 2.67%) and 24.34% (SD ± 4.09%), respectively, with p-value of < 0.001. Conclusions: PAX 1 gene methylation has a promising role in identifying high-grade lesions and invasive cancer.

RESUMEN
PURPOSE: The prognostic role of endometriosis amongst women with ovarian clear cell carcinoma (OCCC) remains debatable. The aim of this study was to ascertain the effect of endometriosis on the prognosis of OCCC. METHODS: A retrospective review of the medical records of 94 women diagnosed and treated for OCCC at a tertiary gynaecological cancer centre in the UK, spanning the period 2010-2019. Women were divided into two groups according to the presence of endometriosis. Clinico-pathological characteristics, progression-free survival (PFS) and overall survival (OS) were collated between the two groups. RESULTS: Forty-six cases of endometriosis-free OCCC (Ef-OCCC) were collated with 48 cases of endometriosis-related OCCC (Er-OCCC). There was no significant difference between the two groups regarding age (p-value = 0.2), FIGO stage (p-value = 0.8), residual disease (RD) (p-value = 0.07), adjuvant chemotherapy agent (p-value = 0.4) or chemo-resistance (p-value = 0.9). The presence of endometriosis did not significantly affect either OS or PFS. The median OS in the Ef-OCCC and Er-OCCC was 55.00 (95% CI 32.00-189.00) and 71.00 (95% CI 47.00-97.00; log rank = 1.35, p-value = 0.2) months. The median PFS in the Ef-OCCC and Er-OCCC group was 39.00 (95% CI 19.00-143.00) and 39.00 (95% CI 19.00-62.00; log rank = 0.7, p-value = 0.4) months. Survival differences between the two groups were not significant after stratification analysis for independent prognosticators. CONCLUSION: Endometriosis was not independently associated with the prognosis of OCCC either in crude analysis or after stratification for stage and RD. Further larger, well-designed prospective studies are warranted to draw firmer conclusions on the intrinsic link between endometriosis and OCCC.

Cervical cancer is the fourth most common cancer in women in the world. To eliminate cervical cancer by 2030, the World Health Organization has given the target of 70 per cent coverage of twice lifetime screening. A multitude of screening methods are available, including cytology, human papillomavirus (HPV) DNA testing and visual inspection tests. Precision tests, including molecular and protein biomarkers such as DNA methylation, p16 immunostaining, and HPV mRNA testing help to enhance specificity of the screening. Worldwide HPV DNA testing with or without cytology is used as a screening method of choice, while in resource-poor settings, visual inspection tests are recommended. The major hurdle is a uniform and systematic implementation with a recall method in the population. Besides, controversies still exist regarding strategies to manage HPV-positive women and developing guidelines to screen the vaccinated population.

OBJECTIVE: To study the accuracy of frozen section biopsy for endometrial pathology in high-risk women with abnormal uterine bleeding (AUB). STUDY DESIGN: A case-control study was conducted between November 2017 to April 2019, a total of 150 women with postmenopausal bleeding, perimenopausal AUB, and high-risk women of age < 40 years with AUB were recruited. All women underwent transvaginal sonography and Doppler, based on age-appropriate endometrial thickness cut-offs 80 women then underwent hysteroscopy. Based on hysteroscopy, women suspicious of malignancy were taken as cases (n = 40) and those with benign findings as controls (n = 40). All cases and controls underwent dilatation and curettage (D & C) with frozen section (FS) and routine histopathology. RESULTS: The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), positive likelihood ratio (LR), negative LR, and overall test accuracy of FS were 90.9%, 93.19%, 83.33%, 96.19%, 13.8, 0.1 and 86.25% respectively for diagnosing endometrial hyperplasia and cancer taking histopathology as the gold standard. Correlation between frozen section biopsy and histopathology was highly significant (p < 0.001) on D & C specimens and the level of agreement was good (K = 0.778). CONCLUSION: In women suspicious of malignancy on hysteroscopy, frozen section has high accuracy on D&C specimen and can be used to diagnose endometrial hyperplasia and cancer in an effort to fast-track investigations and work-up for definitive treatment while awaiting final histopathology.

BACKGROUND: To assess the efficacy of the combined maneuvers in evaluation of post-laparoscopic pain. MATERIAL AND METHODS: A randomized controlled study was conducted. Sixty-four women were included in the study and were randomly divided into two groups. Intervention group received combined maneuvers such as intraperitoneal normal saline infusion, pulmonary recruitment maneuver and local bupivacaine instillation at port sites after laparoscopic surgery. Control group received routine care. MAIN OUTCOME MEASURES: Upper abdominal pain, shoulder pain and incision site pain were noted in both groups at 3, 6, 12, 24 and 48 h postoperatively. RESULTS: The median interquartile range (in centiles) of upper abdominal pain score 3, 6 and 12 h postoperatively in the intervention group was 1.0 (0.25-1.0), 1.0 (0.0-1.0) and 0.50 (0.0-1.0), and in the control group, the values were 2.0 (2.0-1.0), 2.0 (2.0-1.0) and 1.0 (0-1.0) at 3, 6 and 12 h, respectively (p < 0.000). The median interquartile range of shoulder pain score 3, 6 and 12 h postoperatively in the intervention group was 0.0 (0.0-1.0), 0.0 (0.0-0.75) and 0.0 (0.0-1.0), and in the control group, the values were 1.0 (0.0-2.0), 1.0 (0.0-1.75) and 1.0 (0-1.0) at 3, 6, and 12 h. The upper abdominal pain and shoulder pain relief was significantly more in the intervention group than in the control group in the first 12 h of surgery. CONCLUSION: Combined maneuvers could significantly reduce post-laparoscopic upper abdominal and shoulder pain.Clinical Trial CTRI Registration Number-CTRI/2017/07/0089, web address of CTRI-http://ctri.nic.in.
RESUMEN
OBJECTIVE: To compare the AV Magnivisualizer with colposcopy to detect cervical intraepithelial neoplasia (CIN) using the Swede scoring system. METHODS: Cross-sectional study conducted in a tertiary care hospital from May 2017 to March 2018. One hundred women with positive results at visual inspection with acetic acid underwent cervical inspection using the Magnivisualizer followed by a colposcope. Biopsies were taken if the Swede score was greater than 4. Pregnant women, women with an obvious cervical growth, acute cervicitis, or prior cervical surgery were excluded. Diagnostic accuracy of the Magnivisualizer and colposcope was calculated for high-grade lesions (CIN 2/CIN 2+) and agreement was compared between the two modalities. RESULTS: The sensitivity, specificity, and positive and negative predictive values of the Magnivisualizer were 88.2%, 70.0%, 50.0%, and 94.6%, respectively, to detect high-grade lesions at a Swede score cutoff of 5 or more. The area under the curve for the Magnivisualizer was 0.80 (95% CI, 0.67-0.92), which was comparable with colposcopy (AUC 0.86; 95% CI, 0.76-0.96). There was very good agreement between the Magnivisualizer and colposcopy (κ=0.865, P<0.001) for high-grade lesions. CONCLUSION: The Magnivisualizer had high diagnostic accuracy to detect high-grade CIN in screen-positive women, which was comparable with colposcopy.

OBJECTIVE: To compare the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and platelet indices between women with pre-eclampsia and normotensive pregnant women. METHODS: A cross-sectional study conducted from January to July 2017 at a tertiary care hospital in Delhi, India. The study compared pregnant women aged 18-40 years with pre-eclampsia diagnosed at term with healthy pregnant women matched for gestational age. Venous blood samples were drawn and complete blood count was analyzed. The parameters recorded were hemoglobin, red cell distribution width (RDW), platelet count, mean platelet volume (MPV), plateletcrit, and platelet distribution width. RESULTS: There were 67 women included in each group. NLR was higher in women with pre-eclampsia compared with the control group (6.8 ± 7.6 vs 3.0 ± 0.98; P=0.001). Both PLR (14.18 ± 14.4 vs 9.54 ± 3.6; P=0.012) and MPV (9.45 ± 1.19 vs 9.02 ± 1.1; P=0.029) were higher in the study group compared with the control group. Platelet count was lower in pre-eclamptic women compared with the control group (188 ± 89.7 vs 200.1 ± 62.36; P=0.014). RDW was also higher in the study group (P=0.025). CONCLUSIONS: The present study found that the inflammatory markers NLR, PLR, RDW, and MPV were higher in women with pre-eclampsia. Measuring NLR and PLR may be useful in predicting pre-eclampsia among women at high risk during prenatal follow-up.

BACKGROUND: Ovarian cancer is associated with a high relapse rate and is the fifth leading cause of cancer deaths in women. The genetic profile of a tumor is responsible for deciding response to chemotherapeutic agents. In this study, we investigate the relation between survivin and p53 expression and response to chemotherapeutic agents of primary cultures of ovarian cancer cells established from ascitic fluid. MATERIALS AND METHOD: Ascitic fluid and Dulbecco's modified Eagle medium was mixed in equal proportion in culture flasks and incubated to establish primary culture. The cells were treated with different combinations of carboplatin and paclitaxel with and without survivin small interfering RNA transfection. Cell survival was estimated by MTT assay. Survivin and p53 expression was quantified by real-time polymerase chain reaction. RESULTS: Out of 19 ascitic fluid samples, 13 primary cultures of ovarian cancer cells were established. The half maximal inhibitory concentration doses of carboplatin (≥70 µg/mL) and paclitaxel (≥18 µg/mL) were high for 10/13 and 5/13 patients, respectively. Survivin messenger RNA expression was significantly downregulated on treatment with carboplatin (100 µg/mL), paclitaxel (12.5 µg/mL), and a combination of carboplatin (50 µg/mL) and paclitaxel (6.25 µg/mL). Only paclitaxel-treated ovarian cancer cells showed decrease in expression of p53. Survivin small interfering RNA increased sensitivity of the primary cultures to chemotherapeutic agents. CONCLUSIONS: The present study highlights the fact that establishing primary cultures from ascitic fluid may help to develop personalized treatment regime for individual patients based on their molecular profile. Our study also shows that supplementing taxols drugs with survivin inhibitors may prove to be beneficial in the treatment of ovarian cancer patients.

OBJECTIVE: Ovarian cancer is the seventh leading cause of cancer death worldwide. This is mainly due to late diagnosis and high rate of relapse and resistance following chemotherapy. In the present study, we describe simple and cost-effective method to establish primary culture from ascitic fluid and solid tumor obtained from epithelial ovarian carcinoma patient, which may provide a better tool for in vitro testing of drug sensitivity and designing individualized treatment protocol. METHODS: Complete Dulbecco modified Eagle medium (DMEM) was prepared by supplementing DMEM with 10% fetal bovine serum and antibiotics (ciprofloxacin and amphotericin B). Establishment of primary culture of ovarian cancer cells from ascites fluid and solid tumor was done by using complete DMEM media. RESULTS: Primary cultures of ovarian cancer cells were established from ascitic fluid and solid tumor tissue. Of the 7 ascitic fluid samples, we were able to establish 5 primary cultures of ovarian cancer cells. All the 7 samples were diagnosed as serous papillary adenocarcinoma. Some fibroblasts were also attached to culture flask on day 4; they were removed by exposing them to trypsin for a brief period. On day 7, grape-like clusters were visualized under inverted microscope. The cells became confluent on the 10th and 11th day and showed cobblestone appearance, which is a hallmark of ovarian cancer cells. Senescent irregularly shaped cells that have ceased dividing were seen after 8 to 10 passages. CONCLUSION: This study highlights the fact that establishing primary cultures from ascitic fluid or solid tumor tissue may help us to understand the molecular profile of the cancer cells, which allow us to select the best chemotherapeutic agent for ovarian cancer patients and thus take a step toward patient-tailored therapy so that patients are not exposed to drugs to which they are not likely to respond.

Collision tumours are defined by co-existence of two tumours in the same or adjacent organs which are topographically and histologically distinct with minimal or no histological admixture. Collision tumours have been described in many organs notably thyroid, brain, adrenal gland, stomach and rarely uterus. Most of the collision tumours reported in uterus have two components; an adenocarcinoma and a sarcoma. We report a case of a 60-year-old lady who presented with complaints of post-menopausal bleeding. A cervical biopsy was performed which showed a non-keratinizing squamous cell carcinoma of cervix. Intra-operatively the uterus was bulky with a 6 cm x 5 cm polypoidal mass in the endometrial canal along with a 2 cm friable cervical growth. The fleshy uterine cavity mass was a spindle cell tumour with moderate pleomorphism and frequent mitosis. It was immunopositive for CD10 and negative for smooth muscle actin and cytokeratin 5/6. The other growth showed non-keratinizing squamous cell carcinoma which was positive for cytokeratin 5/6. Based on the distinct topographical location and limited areas of tumour admixture of the two tumours, a diagnosis of collision tumour of uterus comprising of endometrial stromal sarcoma (high grade) uterus and squamous cell carcinoma cervix was made.
RESUMEN
Levetiracetam (LEV) is a relatively newer anticonvulsant drug used to treat epilepsy and is approved by United States Food and Drugs Administration (USFDA). The drug binds to a synaptic vesicle glycoprotein and inhibits presynaptic calcium channels, thus reducing neurotransmitter release. Commonly reported side effects include drowsiness, weakness, unsteady gait, mood changes and loss of appetite. Like most other antiepileptics, it is a Category C drug in pregnancy. We report the first case of facial dysmorphism in the neonate of a mother taking LEV antenatally. A 30-year-old lady, G2P1L1 presented at 38 weeks gestation with history of previous caesarean and leaking per vaginum. She was a known epileptic, taking carbamazepine since three to four years. She was switched over to LEV at fifth week of pregnancy. Her antenatal period was uneventful. Basic investigations including anomaly scan were normal. Unfavourable cervix necessitated caesarean section. Neonate (female) had dysmorphic facies with bilateral preauricular appendages and lateral cleft. Infantogram was suggestive of bifid vertebra in thoracic region. Computed Tomography (CT) scan chest revealed bifid vertebral body at D5 level with fusion of spinous process of D5 and D6 vertebra on left side. This is the first case of LEV induced facial dysmorphism, highlighting the need of further studies on LEV safety during pregnancy.
