    This study was conducted to determine the effect of ethnicity on maternal, placental and neonatal parameters. Maternal, placental, and the newborn parameters were corrected for gestational age. The male:female sex ratio was 1:1.03. One hundred and forty-four freshly delivered placentae from 55 Malaysian, 51 Chinese, and 38 Indian normal healthy patients were collected and standard stereological methods used to estimate the placental parameters. Pearson's correlation, Spearman's correlation and 1-way ANOVA were used to test significance of differences. Placental surface area, placental weight and placental volume of Indians were lower than Malays (P< 0.05). Placental weight correlated significantly with neonatal length (r=0.527), birthweight (r=0.665), head circumference (r=0.371) and booking weight (r=0.193) while placental volume correlated with neonatal length (r=0.588), birthweight (r=0.688), head circumference (r=0.384), parity (r=0.202) and booking weight (r=0.219) at P< 0.05. Indian babies weight and length were less than Chinese and Malay babies (P< 0.05) while booking weight of Indian mothers was less than those of Chinese mothers (P< 0.05). Even after being corrected for booking weight, placental parameters of Indian patients were still significantly less than Malays and Chinese (P< 0.05).

    INTRODUCTION: The study aims to evaluate and report on the clinical characteristics, incidence, risk factors and associated complications of emergency and planned peripartum hysterectomy in a single training and research tertiary health care centre in Malaysia.

    MATERIALS AND METHODS: We conducted a 6-year retrospective cross-sectional study from the 1st January 2016 until 31st December 2021. Clinical, demographic characteristics, perioperative parameters, operative indications, blood loss, maternal/neonatal outcomes and complications were analysed. Patients were subdivided, analysed and studied in two subgroups- emergency hysterectomy (EH) and planned hysterectomy (PH).

    RESULTS: There were 65 cases of peripartum hysterectomy out of total 100,567 deliveries, with a prevalence rate of 0.06%. Overall, the majority of patients were multiparous (96.9%), having previous caesarean scar (73.8%) or diagnosed with placenta praevia (75.4%). More than half of the total patients (61.5%) have both previous caesarean scar and concomitant placenta praevia. EH was carried out in 39(60%) patients while 26(40%) patients underwent PH. The only indication for surgery in the PH group (100%) was abnormal placentation while the most common indication for surgery in the EH group (53.8%) was postpartum haemorrhage related to abnormal placentation. Patients who underwent EH were more likely to have massive blood loss (p=0.001), require ICU admissions (p=0.001), have DIVC cycles transfused (mean [SD] regime: 1.35 [0.95] vs 0.54 [0.99]; p=0.002), have lower postoperative haemoglobin level (mean [standard deviation, SD] haemoglobin: 9.23g/l [SD1.8] vs. 10.8 g/l [SD1.86]; p=0.001) and have higher difference between pre/post operative haemoglobin level (mean [SD] haemoglobin difference: 1.78g/l [SD6.34] vs 0.32g/l [SD1.7]; p=0.008) compared to patients with PH. Red blood cell transfusion, operating time, length of stay, weight of babies and Apgar score between two groups showed no significant differences. A significant reduction of blood loss between the first and the second half duration of the study (mean [SD] blood loss: 6978 ml [SD 4999.45] vs. 4100ml [SD2569.48]; p=0.004) was also observed. In the emergency group, 'non-placental cause' EH required significantly more red blood cell transfusion than 'placental cause' (p<0.05) while in the PH group, no significant difference was observed between the occlusive internal iliac artery 'balloon' and 'no balloon' subgroup in terms of operating time, total blood loss or blood transfusion. Overall complications showed more cases of post operative fever and relaparotomy in the EH group (18.4% vs. 7.6%) while urinary tract injuries including injuries to bladder and ureter occurred only in the PH group (9.4% vs. 0%).

    CONCLUSION: The majority of peripartum hysterectomy cases are due to placenta accreta spectrum disorders. Planned peripartum hysterectomies have a lower morbidity rate compared to emergency hysterectomies. Therefore, early identification of placenta accreta spectrum disorders and timely planning for elective procedures are crucial to minimise the need for emergency surgery.

    Dioscorea hispida var. daemona (Roxb) Prain & Burkill (DH), also known a tropical yam or intoxicating yam is a bitter wild tuber which is consumed as a staple food and traditionally used as a remedy in Malaysia. However, DH is also notorious for its intoxicating effects and there is currently a dearth of study of possible effects of DH on liver and placental tissues and hence its safe consumption warrants in-depth investigation. This study was therefore designed to investigate into the effect of DH on liver and placenta of pregnant rat via histopathological examination. Thirty pregnant Sprague-Dawley rats were randomly divided into five groups consisting of a control (distilled water) and four DH aqueous extract groups (250, 500, 1000 and 2000 mg/kg body weight). The extracts were administered via oral gavage daily throughout the study and animals were sacrificed on day 21. Paraffin-embedded, hematoxylin and eosin stained sections of placenta and liver were examined. Significant changes (p placenta of rats. However, the underlying mechanism and phytochemicals inducing the observed toxicity require further investigation.

    A 40-year-old woman, a grand multipara with uncertain gestation, presented with severe, prolonged diarrhoea. She was previously diagnosed to have melanoma. Examination revealed gross ascites with hepatosplenomegaly and uterus corresponding to 29 weeks gestation. An emergency caesarean section confirmed widespread metastases to the ovaries, mesentery and placenta. A viable male foetus was delivered with features of intrauterine growth restriction. The baby survived, but the mother died a week later. This case highlights the importance of thoroughly assessing placentas and babies of patients with melanoma for metastases.

    We report a case of congenital cytomegalovirus and Herpes simplex virus infection suspected via ultrasound indicated by the presence of fetal cerebral abnormalities. The pregnancy was electively terminated at 31 weeks of gestation. The postmortem examination of the foetus showed brain with lissencephaly. The histopathological examination revealed numerous enlarged cells containing cytomegalic inclusions and multinucleated giant cells in multiple fetal organs and placenta. Documented evidence of histopathological detection of cytomegalovirus inclusions in multiple organs are very sparse in literature. This case highlights the causal relationship of viral infections in early pregnancy and abnormalities of the central nervous system.

    Placenta praevia  is a known obstetric condition  that causes complications  to mother and fetus. This study was done to evaluate the knowledge of placenta praevia amongst the obstetric patients. A cross sectional study was carried out in Hospital Ipoh, Perak among 323 antenatal and postnatal patients. Socio-demographic parameters (ie age, race, parity, occupation, educational  level) and history of placenta praevia were studied  in relation to level of knowledge and attitude towards placenta praevia. Twenty (6.2%) from 323 women had current or past history of placenta praevia. Three had history of placenta praevia while 17 had current placenta praevia with prevalence of 5.3%. The mean score of knowledge achieved by patients was 11.8 which indicated overall poor knowledge. Occupation, level of education and history of placenta praevia were found to have a relationship with level of knowledge regarding placenta praevia in all obstetric patients. There was a significant relationship between attitude of patients with current and history of placenta praevia to level of knowledge regarding placenta praevia. (p=0.037,

    Placenta previa is a condition when the placental tissue extends over the internal cervical os. It is associated with
    maternal and fetal morbidity and mortality. With intrauterine death, the mode of delivery will be more difficult to
    decide. Here, we report a case of 30 years old G3P2 with placenta previa major diagnosed with intrauterine death at
    29 weeks gestation who was managed conservatively and delivered vaginally with minimal complication. A good
    patient selection and thorough counseling, patient with placenta previa major and intrauterine death still can be safely
    delivered vaginally.

    OBJECTIVES: Fingerprints have so far been used for determining the basis of certain malignant diseases, with positive outcomes. Considering the high rates of cancer-related mortality in Iran, this study was conducted for the purpose of examining the dermatoglyphic pattern of fingers in patients with gynecological cancers as compared to healthy people.

    STUDY DESIGN: The present study was conducted on 151 women with gynecological cancers as the case group and 152 healthy women with no history of such cancers as control group. The dematographic details of participants from both control and case groups were collected using a checklist, and the pattern of their fingerprints was prepared and examined. The data were analyzed for their significance using chi-square test and t- test. Odds ratio with 95% confidence intervals were calculated.

    RESULTS: Dermatoglyphic analysis showed that arch and loop patterns significantly changed in cases group as compared to control. However, the odds ratio suggested that loop pattern in 6 or more fingers might be a risk factor for developing gynecological cancers.

    CONCLUSION: Our results showed that there is an association between fingerprint patterns and gynecological cancers and so, dermatoglyphic analysis may aid in the early diagnosis of these cancers.

    The outbreak of the coronavirus disease 2019 (COVID-19) pandemic, caused by novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has resulted in a global public health crisis, causing substantial concern especially to the pregnant population. Pregnant women infected with SARS-CoV-2 are at greater risk of devastating pregnancy complications such as premature delivery and stillbirth. Irrespective of the emerging reported cases of neonatal COVID-19, reassuringly, confirmatory evidence of vertical transmission is still lacking. The protective role of the placenta in limiting in utero spread of virus to the developing fetus is intriguing. The short- and long-term impact of maternal COVID-19 infection in the newborn remains an unresolved question. In this review, we explore the recent evidence of SARS-CoV-2 vertical transmission, cell-entry pathways, placental responses towards SARS-CoV-2 infection, and its potential effects on the offspring. We further discuss how the placenta serves as a defensive front against SARS-CoV-2 by exerting various cellular and molecular defense pathways. A better understanding of the placental barrier, immune defense, and modulation strategies involved in restricting transplacental transmission may provide valuable insights for future development of antiviral and immunomodulatory therapies to improve pregnancy outcomes.

    Pre-natal diagnosis of intra-abdominal pregnancy is difficult. Ultrasound has been the frontline modality to date; however, it gives a diagnostic error of 50-90% and its use is disappointing. In recent years, MRI has emerged as an appealing imaging modality. With its good soft tissue contrast and non-ionizing property, it acts as a means of definitive non-invasive assessment before surgical intervention when ultrasound is inconclusive.

    Intra-umbilical injection of oxytocin has been used to hasten placental separation in retained placenta. A randomised controlled trial was done on 35 consequent women who fulfilled the criteria for retained placenta at the Department of Obstetrics & Gynaecology Ipoh Hospital. Nineteen patients who were recruited into the study group received intraumbilical injection of 301U oxytocin in 27mls saline. Another 16 patients who were in the control group received 30mls of 0.9% sodium chloride (placebo). The primary outcome measured was the need for manual removal of placenta (MRP). Nine out of the 19 patients in the oxytocin group required MRP while 10/16 in the control group required MRP. There was a 24% reduction (95% C.I. 0.41 to 1.39) in the need for MRP in the study group compared to the saline group. our results indicate that intra-umbilical vein injection of oxytocin is not clinically useful for the removal of a retained placenta.

    Caesarean hysterectomy is a useful surgical procedure. However, the increased blood supply to the pelvis during pregnancy, distortion of the anatomy caused by the enlarged uterus, fragility of oedematous pelvic tissues and adhesions from prior caesarean sections predispose to poor haemostasis and urinary tract injuries. In this series all the cases were done as an emergency procedure and, despite the multiple obstetric complications, there was no maternal mortality and the incidence of post-operative morbidity was low.

    Acid alpha-glucosidase from the placenta was electrophoretically surveyed in a total of 633 Malaysians, 236 of Malay, 261 of Chinese and 136 of Indian ancestries. A new variant, alpha-glucosidase 3-1 was observed in 1 Malay and 3 Indians. A polymorphism for this enzyme was observed among Indians, but in Chinese and Malays variants are rare. Phenotype 2-1 was observed once in a Chinese and once in a Malay.

    Malaysians of Malay, Chinese, and Indian ancestries were electrophoretically phenotyped for Amy1 and saliva esterase region 1 (Set-1) from saliva, Amy2 from plasma, soluble and mitochondrial GOT and PGM3 from leukocyte and placenta. Kadazans and Bajaus, the indigenous people of Sabah, East Malaysia were surveyed for Amy2. Three types of variants were observed for Amy1, one type for Amy2. Only Indians were found to be polymorphic for Amy1. Two GOTs 2-1 and three GOTm 2-1 variants were found among 281 Chinese while three GOTm 2-1 variants were found among 311 Malays. Malaysian Malays, Chinese, and Indians were found to be polymorphic for Set-1 and PGM3. The gene frequencies in Malays are Set-1F=0.601 +/- 0.021, Set-1S = 0.399 +/- 0.021; PGM13 = 0.788 +/- 0.020, PGM23 = 0.212 +/- 0.020; in Chinese Set-1F = 0.497 +/- 0.028, Set-1S = 0.503 +/- 0.028; PGM13 = 0.745 +/- 0.24, PGM23 = 0.255 +/- 0.024; in Indians, Set-1F = 0.449 +/- 0.031, Set-1S = 0.551 +/- 0.031; PGM13 = 0.755 +/- 0.029, PGM23 = 0.245 +/- 0.029.

    AIMS: This trial was conducted to determine the efficacy of umbilical vein injection of 400 versus 800 μg misoprostol to deliver retained placenta and to compare both regimens regarding the time of placental delivery and amount of vaginal blood loss.

    METHODS: A double-blind, multicenter randomized clinical trial was undertaken in four teaching hospitals in the North of Iraq and Al-Azhar University Hospital in Egypt, from March 2016 to May 2019. Group I (274 women) received 400 μg misoprostol and group II (249 women) received 800 μg misoprostol. Data regarding the time of placental separation and amount of vaginal blood loss were analyzed and proportions were compared between groups using Chi-squared test. Mean values were compared using the Student's t-test. The Mann-Whitney test was used to determine the median of vaginal blood loss.

    RESULTS: The proportion of placental separation was 84.3% among women in group I and 86.7% of women in group II. The mean time of placental separation was 18.86 ± 234.2 and 17.86 ± 213.09 min in groups I and II, respectively (P placenta.

    Mesenchymal stem cells (MSC) generated from human umbilical cord (UC-MSC) and placenta (PLC-MSC) were assessed and compared for their immunomodulatory function on T cells proliferation by analysis of the cell cycle. Mitogen stimulated or resting T cells were co-cultured in the presence or absence of MSC. T-cell proliferation was assessed by tritiated thymidine ((3) H-TdR) assay and the mechanism of inhibition was examined bycell cycle and apoptosis assay. Both UC-MSC and PLC-MSC profoundly inhibited the proliferation of T-cell, mainly via cell-to-cell contact. MSC-mediated anti-proliferation does not lead to apoptosis,but prevented T cells from entering S phase and they therefore accumulated in the G(0) /G(1) phases. The anti-proliferative activity of MSC was related to this cell cycle arrest of T-cell. UC-MSC produced a greater inhibition than PLC-MSC in all measured parameters.

    Our aim was to determine the disposition of creatine in ovine pregnancy and whether creatine is transferred across the placenta from mother to fetus. Pregnant ewes received either1) a continuous intravenous infusion of creatine monohydrate or saline from 122 to 131 days gestation, with maternal and fetal arterial blood and amniotic fluid samples collected daily for creatine analysis and fetal tissues collected at necropsy at 133 days for analysis of creatine content, or2) a single systemic bolus injection of [13C]creatine monohydrate at 130 days of gestation, with maternal and fetal arterial blood, uterine vein blood, and amniotic fluid samples collected before and for 4 h after injection and analyzed for creatine, creatine isotopic enrichment, and guanidinoacetic acid (GAA; precursor of creatine) concentrations. Presence of the creatine transporter-1 (SLC6A8) and l-arginine:glycine amidinotransferase (AGAT; the enzyme synthesizing GAA) proteins were determined by Western blots of placental cotyledons. The 10-day creatine infusion increased maternal plasma creatine concentration three- to fourfold (P< 0.05) without significantly changing fetal arterial, amniotic fluid, fetal tissues, or placental creatine content. Maternal arterial13C enrichment was increased (P< 0.05) after bolus [13C]creatine injection without change of fetal arterial13C enrichment. SLC6A8 and AGAT proteins were identified in placental cotyledons, and GAA concentration was significantly higher in uterine vein than maternal artery plasma. Despite the presence of SLC6A8 protein in cotyledons, these results suggest that creatine is not transferred from mother to fetus in near-term sheep and that the ovine utero-placental unit releases GAA into the maternal circulation.

    BACKGROUND: This study assessed the effects of propolis alone or combined with insulin on maternal status, pregnancy outcomes and placental oxidative stress in streptozotocin-induced diabetic rats.

    METHODS: Forty female rats were randomly assigned into five groups (n = 8/group) i.e. non-DM (non-diabetes), DM (diabetes), DM + Propolis (diabetes on propolis orally); DM + Insulin (diabetes on insulin subcutaneously) and DM + Combined (diabetes on propolis and insulin) groups. Propolis and insulin were given at 300 mg/kg/day orally and 5.0 IU/kg/day subcutaneously, respectively, for 4 weeks.

    RESULTS: Fasting blood glucose, conception period, implantation losses, foetal blood glucose and placental oxidative stress markers such as malonaldehyde and protein carbonyl were significantly higher while maternal weight gain, foetal body weight and total antioxidant capacity were significantly lower in DM group compared with non-DM group. These changes were significantly improved in rats treated with propolis or insulin alone with greater significant effects in rats treated with both propolis and insulin.

    CONCLUSION: This study may suggest the protective effects of propolis against DM-induced impaired pregnancy outcomes and placental oxidative stress with greater effects when combined with insulin.
