ABSTRACT
BACKGROUND: For appropriate management of hemolytic disease of the fetus and newborn (HDFN), it is important to detect irregular red cell antibody in the antenatal period. Though it is a simple one-step method, it is not part of routine antenatal screening in many developing countries. To reiterate the importance of antenatal antibody screening, we have assessed the frequency and clinical significance of irregular red cell antibodies in our patient population. MATERIALS AND METHODS: A prospective study was carried out from October 2013 to May 2015 at a tertiary care center from south India. All antenatal samples received by the laboratory for red cell antibody screening were screened using a commercial three-cell screening panel. Antibody identification along with further Immunohematological techniques as required were performed for cases with positive screening results. Neonates of the alloimmunized cases were followed up to determine the clinical significance of the antibody. RESULTS: A total of 2336 antenatal mothers were screened for red cell antibodies. The overall rate of alloimmunization in the study group was 2.27%. Alloimmunization rate among RhD-negative pregnancies was 6.9%. Other than anti-D (49%), we identified anti-D + anti-C (5%), anti-G (5%), anti-c (5%), anti-E (2%), anti-e (2%), anti-H (Bombay phenotype) (7%), anti-M (2%), anti-Lea (2%), anti-Leb (12%), and autoantibodies (9%) in the maternal serum. Anti-D, anti-D + anti-C, anti-G, anti-c, and anti-H were found to be clinically significant in this study. CONCLUSION: This study showed that 1 in 125 RhD-positive pregnancies can develop red cell alloantibodies. Hence, implementing routine antenatal antibody screening irrespective of RhD status is essential.

Background: Present study carried out in a tertiary referral hospital in South India attempts to determine the predictive value of integrated screening at 11-14-week antenatal visit. Objectives: To determine the detection rate of fetal abnormalities at 11-14 weeks and also to predict the placental dysfunction disorders based on early integrated evaluation. Method: Integrated screening performed on 440 women between 11 and 14 weeks, including detailed maternal history [medical history, bad obstetric history (BOH)], body mass index (BMI), mean arterial pressure (MAP), detailed ultrasound and maternal serum biochemistry as part of combined first-trimester screening for aneuploidy. Results: There were two proven Down's syndrome foetuses; both detected with combined screening test. There were 12 fetuses with major anomalies, out of whom 7 (58.3%) detected in 11-14-week scan. Among 440, 114 pregnancies (25.9%) developed complications in pregnancy, including 33 (7.5%) gestational hypertension, 8 (1.8%) pre-eclampsia, 41 (9.38%) SGA, 13 (2.9%) abortions, 22 (5%) indicated and 9 (2.04%) spontaneous preterm deliveries, 38 (8.63%) GDM and 3 (0.6%) stillbirth/IUD. Among the risk factors, age >35 years, BMI >23 kg/m2, BOH, MAP >105 mmHg and PAPP-A <0.5 MoM correlated well with adverse outcome. Using early integrated screening, 78.9% of obstetric complications could be predicted although 306 (69.5%) were labeled high risk, among whom 90 (29.4%) developed adverse pregnancy outcomes. Conclusions: Majority of fetal abnormalities can be detected, and majority adverse pregnancy outcomes can be predicted at 11-14-week antenatal visit, although this study shows high screen positivity and low specificity in a tertiary referral unit.
ABSTRACT
OBJECTIVES: To study the neonatal respiratory morbidity in late-preterm neonates. MATERIALS AND METHODS: This study was done over a period of 6 months (November 2014-April 2015) including 120 late-preterm births at a tertiary referral center. RESULTS: Among the 120 late-preterm babies, 42 (35 %) developed respiratory morbidity. Respiratory distress syndrome (RDS) developed in 43 % of the babies who had not received steroid prophylaxis against 25.8 % receiving the same (p < 0.05). Among the indicated late-preterm deliveries, 45 % of babies developed respiratory morbidity in comparison with 22 % of the babies born following spontaneous onset of labor (p < 0.05). In the neonates with respiratory morbidity, male babies had a higher incidence than their female counterparts (48 vs. 24 % p < 0.05). Severity of RDS declined from 57 % for babies born at 34 weeks of gestation to 26.3 % for those born at 36 weeks (p 0.14). With each advancing week of gestation a significant reduction in the need for ventilator support (78 % at 34 weeks to 15 % at 36 weeks of gestation p < 0.05) was observed. Presence of antenatal risk factors did not significantly contribute to the respiratory morbidity. CONCLUSION: The severity of respiratory morbidity and need for ventilator support declines with advancing gestational age; hence, every attempt must be made to prolong pregnancy till 36 weeks of gestation.
ABSTRACT
INTRODUCTION: Neurological disorders in pregnancy can be pregnancy related or can be caused by exacerbation of a pre-existing neurological condition or sometimes may even be detected for the first time during pregnancy in which it might be an incidental finding. The diagnosis and management of the neurological disorders in pregnancy is always a challenging task due to varied symptomatology and risks to the fetus. The evaluation and management should be performed in a stepwise fashion and requires multidisciplinary approach. AIM: The present study was conducted with the aim to study the influence of neurological disorders on outcome of pregnancy. MATERIAL AND METHODS: This was a prospective observational study conduted over a period of 1 year (2013-2014) including 54 pregnant women with neurological manifestations. The spectrum of neurological manifestations was divided into-pregnancy specific, incidental and pre-existing neurological disorders for analysis. Five unusual cases with varied manifestations were studied in detail. Any pregnant woman presenting with neurological manifestation, irrespective of gestational age were included in the present study. The neurological manifestation and the obstetric outcome were analysed in the present study. RESULTS: There were 54 women with varied neurological manifestations, majority (74%) of them being primigravida. Seizure was the most common (63%) manifestation. The incidence of pregnancy specific disorder (eclampsia), pre-existing disease (epilepsy) and incidental causes were 40.8%, 37% and 22.2% respectively. Of the 22 women with eclampsia, 15(68%) had seizure during antepartum period and 7(32%) in the postpartum period. Three patients out of 22 who had eclampsia had intrauterine fetal demise on arrival itself, whereas the perinatal outcome was good in the other 19 patients who had live born babies. The most common incidental cause in the present study was tubercular meningitis (44%). There was however a maternal and perinatal mortality in woman with structural malformation who had massive intra-ventricular haemorrhage, secondary to ruptured cerebral cavernoma. Here we have described in detail 5 patients with varied clinical manifestation causing diagnostic dilemma. They are spinal arterio-venous malformation, disseminated toxoplasmosis, massive intra-ventricular haemorrhage (ruptured cerebral cavernoma), tubercular meningitis with cortical venous thrombosis, suspected Bartter syndrome presenting as coma. CONCLUSION: Neurological manifestation during pregnancy may not always be a primary neurological disorder, instead may be manifestation secondary to any systemic illness. Hence, a wide index of suspicion and neuroimaging aids in arriving at the diagnosis certainly improves the pregnancy outcome.
ABSTRACT
INTRODUCTION: Induction of labour (IOL) nowadays is a common procedure in obstetric practice. The success of IOL largely depends upon "favourability" or "readiness" cervix which is traditionally assessed by manual examination and Scored as Bishop Score. However, this method is limited by subjectivity and reproducibility and though done in all the patients prior to IOL, several studies have demonstrated poor correlation between Bishop Score and outcome of labour. OBJECTIVE: To evaluate the role of preinduction transvaginal ultrasonographic (TVS) cervical assessment in predicting labour outcome and to compare its performance against Bishop Score in patients undergoing induction of labour (IOL). SETTING: A tertiary medical college hospital in Southern India. DESIGN: Prospective observational and investigational study. MATERIALS AND METHODS: Transvaginal ultrasound was performed in 131 patients who underwent labour induction at term with intact membranes and live fetus. Bishop Score was assessed by pervaginal examination and was compared with preinduction TVS cervical Score (parameters being cervical length, funneling, position of cervix and distance of presenting part from external os). Labour was induced within one hour of cervical assessment. The labour induction was considered successful if patient could get into active labour i.e., onset of regular uterine contractions (at interval of 2-3 minutes) and cervical dilatation of 4 cm or greater within 24 hours of induction. RESULTS: Labour induction was successful in 86.9% of patients. At cut off Scores of ≥ 4, TVS cervical Score performed better than Bishop Score (Sensitivity 77% vs. 65%, Specificity 93% vs. 86%). ROC analysis indicated that Area Under Curve (AUC) was more for TVS Score (0.90, 95% CI 0.84 - 0.95), compared to Bishop Score. It was found that an increase in cervical length and distance from the os by 1 mm from their means were associated with an increase in odds for failure of induction and there by caesarean delivery by 6.5% and 11% respectively. CONCLUSION: In women experiencing labour induction, transvaginal ultrasound score comprising of five different parameters indicated success of induction better than Bishop Score. Further, two of its components (longer cervical length and increased distance of presenting part from external os) demonstrated significant and independent prediction of the likelihood of failure of induction and risk of operative delivery.
ABSTRACT
An ultra-sensitive high performance liquid chromatography-laser induced fluorescence (HPLC-LIF) based technique has been developed by our group at Manipal, for screening, early detection, and staging for various cancers, using protein profiling of clinical samples like, body fluids, cellular specimens, and biopsy-tissue. More than 300 protein profiles of different clinical samples (serum, saliva, cellular samples and tissue homogenates) from volunteers (normal, and different pre-malignant/malignant conditions) were recorded using this set-up. The protein profiles were analyzed using principal component analysis (PCA) to achieve objective detection and classification of malignant, premalignant and healthy conditions with high sensitivity and specificity. The HPLC-LIF protein profiling combined with PCA, as a routine method for screening, diagnosis, and staging of cervical cancer and oral cancer, is discussed in this paper. BIOLOGICAL SIGNIFICANCE: In recent years, proteomics techniques have advanced tremendously in life sciences and medical sciences for the detection and identification of proteins in body fluids, tissue homogenates and cellular samples to understand biochemical mechanisms leading to different diseases. Some of the methods include techniques like high performance liquid chromatography, 2D-gel electrophoresis, MALDI-TOF-MS, SELDI-TOF-MS, CE-MS and LC-MS techniques. We have developed an ultra-sensitive high performance liquid chromatography-laser induced fluorescence (HPLC-LIF) based technique, for screening, early detection, and staging for various cancers, using protein profiling of clinical samples like, body fluids, cellular specimens, and biopsy-tissue. More than 300 protein profiles of different clinical samples (serum, saliva, cellular samples and tissue homogenates) from healthy and volunteers with different malignant conditions were recorded by using this set-up. The protein profile data were analyzed using principal component analysis (PCA) for objective classification and detection of malignant, premalignant and healthy conditions. The method is extremely sensitive to detect proteins with limit of detection of the order of femto-moles. The HPLC-LIF combined with PCA as a potential proteomic method for the diagnosis of oral cancer and cervical cancer has been discussed in this paper. This article is part of a Special Issue entitled: Proteomics in India.

Choriocarcinoma of the fallopian tube is a rare form of gestational trophoblastic disease. It can be gestational or non gestational choriocarcinoma, based on the origin. Fallopian tube choriocarcinoma has been reported commonly after ectopic pregnancy. Choriocarcinomas are germ cell tumours formed by trophoblastic elements. A 26-year-old lady presented with pain and mass abdomen of 15 days duration. Clinical examination revealed a ovarian tumour with elevated beta HCG. The working diagnosis was ovarian choriocarcinoma. Patient was also found to be having pulmonary artery hypertension due to the metastasis to lungs. Staging laparotomy was done. Histopathology revealed it to be metastatic gestational choriocarcinoma of fallopian tube with vascular emboli. The stage was stage III and WHO scoring of 15. She received Etoposide, Methotrexate, Actinomicin, Cyclophosphamide and Oncovin therapy. Following treatment there was a significant drop in the beta HCG. Patient tolerated the chemotherapy well. This is a rare presentation of choriocarcinoma with good prognosis.
ABSTRACT
Aims and Objectives. (i) To determine the predictive value of cerebrouterine (CU) ratio (middle cerebral artery to uterine artery pulsatility index, MCA/UT PI) in assessing perinatal outcome among hypertensive disorders of pregnancy. (ii) To compare between CU ratio and CP ratio (MCA/Umbilical artery PI) as a predictor of adverse perinatal outcome. Methods. A prospective observational study was done in a tertiary medical college hospital, from September 2012 to August 2013. One hundred singleton pregnancies complicated by hypertension peculiar to pregnancy were enrolled. Both CU and CP ratios were estimated. The perinatal outcomes were studied. Results. Both cerebrouterine and cerebroplacental ratios had a better negative predictive value in predicting adverse perinatal outcome. However, both CU and CP ratios when applied together were able to predict adverse outcomes better than individual ratios. The sensitivity, specificity, positive predictive value, and the negative predictive values for an adverse neonatal outcome with CU ratio were 61.3%, 70.3%, 56%, and 78.9%, respectively, compared to 42%, 57.5%, 62%, and 76% as with CP ratio. Conclusion. Cerebrouterine ratio and cerebroplacental ratio were complementary to each other in predicting the adverse perinatal outcomes. Individually, both ratios were reassuring for favorable perinatal outcome with high negative predictive value.
ABSTRACT
BACKGROUND: Amniotic fluid index (AFI) is one of the major and deciding components of fetal biophysical profile and by itself it can predict pregnancy outcome. Very low values are associated with intrauterine growth restriction and renal anomalies of fetus, whereas high values may indicate fetal GI anomalies, maternal diabetes mellitus, and so forth. However, before deciding the cut-off standards for abnormal values for a local population, what constitutes a normal range for specific gestational age and the ideal interval of testing should be defined. OBJECTIVES: To establish reference standards for AFI for local population after 34 weeks of pregnancy and to decide an optimal scan interval for AFI estimation in third trimester in low risk antenatal women. MATERIALS AND METHODS: A prospective estimation of AFI was done in 50 healthy pregnant women from 34 to 40 weeks at weekly intervals. The trend of amniotic fluid volume was studied with advancing gestational age. Only low risk singleton pregnancies with accurately established gestational age who were available for all weekly scan from 34 to 40 weeks were included in the study. Women with gestational or overt diabetes mellitus, hypertensive disorders of the pregnancy, prelabour rupture of membranes, and congenital anomalies in the foetus and those who delivered before 40 completed weeks were excluded from the study. For the purpose of AFI measurement, the uterine cavity was arbitrarily divided into four quadrants by a vertical and horizontal line running through umbilicus. Linear array transabdominal probe was used to measure the largest vertical pocket (in cm) in perpendicular plane to the abdominal skin in each quadrant. Amniotic fluid index was obtained by adding these four measurements. Statistical analysis was done using SPSS software (Version 16, Chicago, IL). Percentile curves (5th, 50th, and 95th centiles) were constructed for comparison with other studies. Cohen's d coefficient was used to examine the magnitude of change at different time intervals. RESULTS: Starting from 34 weeks till 40 weeks, 50 ultrasound measurements were available at each gestational age. The mean (standard deviation) of AFI values (in cms) were 34 W: 14.59 (1.79), 35 W: 14.25 (1.57), 36 W: 13.17 (1.56), 37 W: 12.48 (1.52), 38 W: 12.2 (1.7), and 39 W: 11.37 (1.71). The 5th percentile cut-off was 8.7 cm at 40 weeks. There was a gradual decline of AFI values as the gestational age approached term. Significant drop in AFI was noted at two-week intervals. AFI curve generated from the study varied significantly when compared with already published data, both from India and abroad. CONCLUSION: Normative range for AFI values for late third trimester was established. Appreciable changes occurred in AFI values as gestation advanced by two weeks. Hence, it is recommended to follow up low risk antenatal women every two weeks after 34 weeks of pregnancy. The percentile curves of AFI obtained from the present study may be used to detect abnormalities of amniotic fluid for our population.

Cervical cancer, the second most common cancer in women, progresses silently over long periods before producing any clinical manifestation. Research in early detection of this condition using proteomic techniques is of very recent origin. We used high-performance liquid chromatography combined with laser-induced fluorescence method in our lab to record the protein profiles of tissue homogenate, cell lysate and serum samples of normal and different stages of malignant conditions of the cervix. Information on protein markers in the protein profiles was derived using various data processing methods including curve resolution. The variations in relative intensities of different peaks with respect to peak height, width and area under the curve from different sample types were compared to get information regarding the concentration of the various proteins and their significance in the induction and metastasis of cervical cancer. The method can be used in diagnosis, follow-up with respect to the progression, remission and effective therapy, in cervical malignancy.

Background. Progressive proteinuria indicates worsening of the condition in hypertensive disorders of pregnancy and hence its quantification guides clinician in decision making and treatment planning. Objective. To evaluate the efficacy of spot dipstick analysis and urinary protein-creatinine ratio (UPCR) in hypertensive disease of pregnancy for predicting 24-hour proteinuria. Subjects and Methods. A total of 102 patients qualifying inclusion criteria were evaluated with preadmission urine dipstick test and UPCR performed on spot voided sample. After admission, the entire 24-hour urine sample was collected and analysed for daily protein excretion. Dipstick estimation and UPCR were compared to the 24-hour results. Results. Seventy-eight patients (76.5%) had significant proteinuria of more than 300 mg/24 h. Dipstick method showed 59% sensitivity and 67% specificity for prediction of significant proteinuria. Area under curve for UPCR was 0.89 (95% CI: 0.83 to 0.95, P < 0.001) showing 82% sensitivity and 12.5% false positive rate for cutoff value of 0.45. Higher cutoff values (1.46 and 1.83) predicted heavy proteinuria (2 g and 3 g/24 h, resp.). Conclusion. This study suggests that random urinary protein : creatine ratio is a reliable investigation compared to dipstick method to assess proteinuria in hypertensive pregnant women. However, clinical laboratories should standardize the reference values for their setup.
ABSTRACT
OBJECTIVE: To compare third stage blood loss in induced vs. spontaneous vaginal deliveries and to correlate the amount of blood loss with the decrease in haemoglobin following deliveries. SETTING: Department of Obstetrics and Gynaecology, Kasturba Hospital Manipal, Karnataka, India. MATERIALS AND METHODS: Blood loss following placental deliveries was measured by using special collection bags in 150 pregnant ladies who delivered vaginally by labour induction and it was compared with that of another 50 women who had spontaneous vaginal deliveries. Haemoglobin values were recorded for each patient prior to labour and after delivery of child. RESULTS: The mean blood loss in induced group was 30 mL more than that in spontaneous group (202 ± 117 mL vs. 172 ± 114 mL), but this was not statistically significant (p=0.12). However, when different methods of induction were compared, oxytocin group was found to have significantly higher blood loss (327 ± 140 mL) as compared to that in other types of labour inductions as well as spontaneous deliveries. Labour induction using prostaglandins did not produce more blood loss as compared that produced by spontaneous deliveries. Both induced and spontaneous delivery groups showed statistically significant drops in post-delivery haemoglobin values, but the drop was relatively more in induced group as compared to that in spontaneous vaginal delivery group (0.96gm/dL vs. 0.56gm/dL), which appeared to be statistically significant (p=0.002). CONCLUSION: Labour induction using prostaglandins is safe as compared to oxytocin usage. Accurate estimation of blood loss is important in all types of deliveries, in order to detect postpartum haemorrhage early, so that appropriate measures can be undertaken.
ABSTRACT
PURPOSE: To assess chemoradiation related acute morbidity in women with carcinoma cervix and to find and correlation between hematologic toxicity and organ system specific damage. MATERIALS AND METHODS: A prospective study was carried out between August 2012 and July 2013 enrolling 79 women with cancer cervix receiving chemo-radiotherapy. Weekly assessment of acute morbidity was done using the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) version 4 and the toxicities were graded. RESULTS: Anemia [77 (97.5%)], vomiting [75 (94.8%)] and diarrhea [72 (91.1%)], leukopenia [11 (13.9%)], cystitis [28 (35.4%], dermatitis [19 (24.1%)] and fatigue [29 (36.71%)] were the acute toxicities noted. The toxicities were most severe in 3rd and 5th week. All women could complete radiotherapy except two due to causes unrelated to radiation morbidity; seven (8.86%) had to discontinue chemotherapy due to leukopenia and intractable diarrhea. Though there was no correlation between anemia and other toxicities, it was found that all with leukopenia had diarrhea. CONCLUSIONS: Chemoradiation for cancer cervix is on the whole well tolerated. Leukopenia and severe diarrhea were the acute toxicities that compelled discontinuation of chemotherapy in two women. Though anemia had no correlation with gastrointestinal toxicity, all of those with leukopenia had diarrhea.

OBJECTIVES: To evaluate the effect of preeclampsia on the cord blood and maternal NRBC count and to correlate NRBC count and neonatal outcome in preeclampsia and control groups. STUDY DESIGN: This is a prospective case control observational study. PATIENTS AND METHODS: Maternal and cord blood NRBC counts were studied in 50 preeclamptic women and 50 healthy pregnant women. Using automated cell counter total leucocyte count was obtained and peripheral smear was prepared to obtain NRBC count. Corrected WBC count and NRBC count/100 leucocytes in maternal venous blood and in cord blood were compared between the 2 groups. RESULTS: No significant differences were found in corrected WBC count in maternal and cord blood in cases and controls. Significant differences were found in mean cord blood NRBC count in preeclampsia and control groups (40.0 ± 85.1 and 5.9 ± 6.3, P = 0.006). The mean maternal NRBC count in two groups was 2.4 ± 9.0 and 0.8 ± 1.5, respectively (P = 0.214). Cord blood NRBC count cut off value ≤ 13 could rule out adverse neonatal outcome with a sensitivity of 63% and specificity of 89%. CONCLUSION: Cord blood NRBC are significantly raised in preeclampsia. Neonates with elevated cord blood NRBC counts are more likely to have IUGR, low birth weight, neonatal ICU admission, respiratory distress syndrome, and assisted ventilation. Below the count of 13/100 leucocytes, adverse neonatal outcome is quite less likely.

Double C2-like domain ß (DOC2B) gene encodes for a calcium-binding protein, which is involved in neurotransmitter release, sorting, and exocytosis. We have identified the promoter region of the DOC2B gene as hypermethylated in pre-malignant, malignant cervical tissues, and cervical cancer cell lines by methylation-sensitive dimethyl sulfoxide-polymerase chain reaction and bisulfite genome sequencing; whereas, it was unmethylated in normal cervical tissues (p < 0.05). The promoter hypermethylation was inversely associated with mRNA expression in SiHa, CaSki, and HeLa cells and treatment with demethylating agent 5-aza-2-deoxycytidine restored DOC2B expression. The region -630 to +25 bp of the DOC2B gene showed robust promoter activity by a luciferase reporter assay and was inhibited by in vitro artificial methylation with Sss1 methylase prior to transient transfections. Overexpression of the DOC2B gene in SiHa cells when compared with controls showed significantly reduced colony formation, cell proliferation, induced cell cycle arrest, and repressed cell migration and invasion (p < 0.05). Ectopic expression of DOC2B resulted in anoikis-mediated cell death and repressed tumor growth in a nude mice xenograft model (p < 0.05). DOC2B expressing cells showed a significant increase in intracellular calcium level (p < 0.05), impaired AKT1 and ERK1/2 signaling, and induced actin cytoskeleton remodeling. Our results show that promoter hypermethylation and silencing of the DOC2B gene is an early and frequent event during cervical carcinogenesis and whose reduced expression due to DNA promoter methylation may lead to selective cervical tumor growth.

This is a case report of a twin pregnancy with one fetus and a coexistent mole diagnosed at 13 weeks. After thorough counseling, the pregnancy was continued as per the patient's desire. The pregnancy was closely monitored with serial S ß hCG, ultrasound for fetal growth, size of molar sac, and theca lutein cysts, which gradually decreased in size during the second trimester of pregnancy. An emergency caesarean delivery was done at 36 weeks due to breech in early labour. A live baby weighing 1.8 kg was delivered in good condition. Her S ß hCG reached normal levels at the end of three weeks, and she is now on post-molar surveillance. Though the general trend is to terminate pregnancy in twins with coexistent mole in anticipation of complications, under close surveillance, optimal outcomes can be achieved. Monitoring of S ß hCG, serial ultrasound for fetal growth, size of molar component, and theca lutein cysts can help to predict good patient outcomes.
ABSTRACT
An extra-adrenal paraganglioma is a rare tumour derived from chromaffin cells of sympathetic ganglia. This report documents a rare case of a non-functional aortocaval paraganglioma in a 24-year-old woman with persistent abdominal pain. Computed tomography revealed a solid mass, measuring 2.5x3cms, localized between the celiac trunk and superior mesenteric artery in aortocaval location along with right ovarian cystic mass. A clinical diagnosis of malignant ovarian tumour with celiac nodal metastasis was made. Excision and pathological analysis of both revealed an aortocaval extra-adrenal paraganglioma and benign ovarian cyst. On serial follow-up the patient was in a good health, asymptomatic and without evidence of tumour recurrence. This case emphasizes the necessity of including extra-adrenal paraganglioma in the differential diagnosis and management of retroperitoneal tumours, despite its rarity.
ABSTRACT
OBJECTIVES: (1) To determine the frequency of maternal near miss, maternal near miss incidence ratio (MNMR), maternal near miss to mortality ratio and mortality index. (2) To compare the nature of near miss events with that of maternal mortality. (3) To see the trend of near miss events. DESIGN: Audit. SETTING: Kasturba Hospital, Manipal University, Manipal, India. POPULATION: Near miss cases & maternal deaths. METHODS: Cases were defined based on WHO criteria 2009. MAIN OUTCOME MEASURES: Severe acute maternal morbidity and maternal deaths. RESULTS: There were 7390 deliveries and 131 "near miss" cases during the study period. The Maternal near miss incidence ratio was 17.8/1000 live births, maternal near miss to mortality ratio was 5.6 : 1, and mortality index was 14.9%. A total of 126 cases were referred, while 5 cases were booked at our hospital. Hemorrhage was the leading cause (44.2%), followed by hypertensive disorders (23.6%) and sepsis (16.3%). Maternal mortality ratio (MMR) was 313/100000 live births. CONCLUSION: Hemorrhage and hypertensive disorders are the leading causes of near miss events. New-onset viral infections have emerged as the leading cause of maternal mortality. As near miss analysis indicates the quality of health care, it is worth presenting in national indices.

AIM: The study objective was to evaluate the pathological changes of the placenta in foetal death and foetal growth restriction and to find correlation of the findings with clinical causes. SETTING AND DESIGN: Prospective study at a tertiary care hospital. MATERIAL AND METHODS: Gross and histopathological examinations of the placentae were carried out in pregnancies with foetal demise (IUD) and Foetal Growth Restriction (FGR). STATISTICAL ANALYSIS: SPSS, version 11.5. RESULTS: Placentae of twenty seven women with foetal demise and of equal number of women with foetal growth restriction were studied. Placental weight was less than 10(th) percentile in 61.5% women in IUD group and in 93% women in the FGR group. Gross examination of placentae showed abnormalities in 12 (44%) women of IUD group and in 16 (59%) women of FGR group. Histopathological abnormalities were observed in 74.1% women of the IUD group and in 66.7% women of FGR group. Placental histopathology correlated with clinical risk factors in 60% women of IUD group and in 40% women of FGR group. Among the women with no clinically explainable cause for IUD and FGR, 86% and 57% had placental histopathological abnormalities respectively. CONCLUSION: The histopathological abnormalities of the placenta can be used to document the clinical causes of foetal demise and growth restriction; it may explain the causes in cases of clinically unexplained foetal demise and foetal growth restriction.
ABSTRACT
A highly objective method, High Performance Liquid Chromatography with Laser Induced Fluorescence (HPLC-LIF) technique was used to study the protein profiles of normal and cervical cancer tissue homogenates. A total of 44 samples including normal cervical biopsy samples from the hysterectomy patients and the patients suffering from different stages of the cervical cancer were recorded by HPLC-LIF and analysed by Principle Component Analysis (PCA) to get statistical information on different tissue components. Discrimination of different stages of the samples was carried out by considering three parameters--scores of factor, spectral residual, and Mahalanobis Distance. Diagnostic accuracy of the method was evaluated using Receiver Operating Characteristic (ROC) analysis, and Youden's index (J) plots. The PCA results showed high sensitivity and specificity (~100) for cervical cancer diagnosis. ROC and Youden's index curves for both normal and malignant standard sets show good diagnostic accuracy with high AUC values. The statistical analysis has shown that the differences in protein profiles can be used to diagnose biochemical changes in the tissue, and thus can be readily applied for the detection of cervical cancer, even in situations where a histopathology examination is not easy because of nonavailability of experienced pathologists.
