Fulltext Uterine arteriovenous malformation

Hashim H, Nawawi O

Malays J Med Sci, 2013 Mar;20(2):76-80.

Uterine arteriovenous malformation (AVM) is a rare condition, with fewer than 100 cases reported in the literature. Despite it being rare, it is a potentially life-threatening condition. This case report describes a 33-year-old woman who presented with secondary post-partum hemorrhage. Transabdominal ultrasound (US) of the pelvis showed increased vascularity with multidirectional flow of the uterus and a prominent vessel, located on the left lateral wall. She also had retained product of conception, which complicated the diagnosis. A uterine artery angiogram confirmed an AVM in the fundal region with an early draining vein. Embolisation of the AVM was performed successfully.

A 66-year-old Malay woman, known hypertensive, presented with post menopausal bleeding associated with clot for three months. She was postmenopausal for last ten years. She also complaints of developing a mass in the abdomen which was growing in size also for last three months. Abdominal examination revealed a twenty week size mass, movable from side to side but unable to get below the mass. Vaginal examination revealed a fleshy fungating mass arising from the uterus coming out through the vagina. Cervix could not be visualized properly. Subsequent histopathology of the removed mass was reported as a Malignant Mixed Mullerian Tumour - Heterologous.

PMID: 25152902 DOI: 10.1155/2014/201514

Leukaemia inhibitory factor (LIF) plays an indispensible role in embryo implantation. Aberrant LIF production is linked to implantation failure. LIF regulates multiple processes prior to and during implantation such as uterine transformation into a receptive state, decidualization, blastocyst growth and development, embryo-endometrial interaction, trophoblast invasion, and immune modulation. Due to its critical role, LIF has been a target for a nonhormonal contraception. In this review, we summarize up-to-date information on the role of LIF in implantation and its role in contraception.

Hassan CH, Karim AK, Ismail NA, Omar MH

Acta Medica (Hradec Kralove), 2011;54(3):125-6.

PMID: 22250483

Ruptured pregnancy in the rudimentary horn of women who have had a vaginal delivery is rare and unpredictable. However, when undiagnosed, this condition could lead to maternal morbidity and mortality. We report a pregnancy at 19 weeks gestation presented with acute abdomen and hypovolemic shock. She was initially thought to have an intrauterine pregnancy with the provisional diagnosis of a ruptured uterus. Intraoperatively, a ruptured non-communicating right rudimentary horn with ex utero pregnancy was discovered.

PMID: 17435832

The possible role of insulin-like growth factors (IGFs) and their receptors (IGFRs) in the pathogenesis of diabetic embryopathy was investigated. Sexually mature female ICR mice of 6-8 weeks old were made diabetic by a single intraperitoneal injection with 200 mg/kg streptozotocin ten days prior to mating. Fallopian tubes and uterine tissues were obtained from the superovulated diabetic and normal mice 48, 72 and 96 hours following human chorionic gonadotropin (hCG) injection. The mRNA expression of IGF-1 and IGF-2 as well as their receptors was determined in the tissues using Real-time Polymerase Chain Reaction (Real-time PCR). The mRNA expression of IGF-1 in the fallopian tube and uterus of the diabetic mice was significantly lower 72 and 96 hours after hCG treatment, respectively, as compared to the controls. The mRNA expression of IGF-1R at 96 hours post-hCG treatment was significantly higher in the fallopian tube and lower in the uterus of the diabetic mice as compared to the controls. The mRNA expression IGF-2 in the fallopian tube was significantly higher 48 and 96 hours after hCG treatment, but was lower in the uterus of diabetic mice 96 hours after hCG treatment as compared to controls. The mRNA expression of IGF-2R in the diabetic mice was significantly higher 48 and 96 hours (the fallopian tube) and 48 hours (uterus) after hCG treatments as compared to the controls. In conclusion, an alteration in mRNA expression of IGFs and their receptors in the diabetic mice as observed in this study could possibly result in diabetic embryopathy.

Fulltext Symphysial fundal height (SFH) measurement in pregnancy for detecting abnormal fetal growth

Robert Peter J, Ho JJ, Valliapan J, Sivasangari S

Cochrane Database Syst Rev, 2015 Sep 08.

PMID: 26346107 DOI: 10.1002/14651858.CD008136.pub3

BACKGROUND: Symphysis fundal height (SFH) measurement is commonly practiced primarily to detect fetal intrauterine growth restriction (IUGR). Undiagnosed IUGR may lead to fetal death as well as increase perinatal mortality and morbidity.

OBJECTIVES: The objective of this review is to compare SFH measurement with serial ultrasound measurement of fetal parameters or clinical palpation to detect abnormal fetal growth (IUGR and large-for-gestational age), and improving perinatal outcome.

SEARCH METHODS: We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (14 July 2015) and reference lists of retrieved articles.

SELECTION CRITERIA: Randomised controlled trials including quasi-randomised and cluster-randomised trials involving pregnant women with singleton fetuses at 20 weeks' gestation and above comparing tape measurement of SFH with serial ultrasound measurement of fetal parameters or clinical palpation using anatomical landmarks.

DATA COLLECTION AND ANALYSIS: Two review authors independently assessed trials for inclusion and risk of bias, extracted data and checked them for accuracy.

MAIN RESULTS: One trial involving 1639 women was included. It compared SFH measurement with clinical abdominal palpation.There was no difference in the two reported primary outcomes of incidence of small-for-gestational age (risk ratio (RR) 1.32; 95% confidence interval (CI) 0.92 to 1.90, low quality evidence) or perinatal death.(RR 1.25, 95% CI 0.38 to 4.07; participants = 1639, low quality evidence). There were no data on the neonatal detection of large-for-gestational age (variously defined by authors). There was no difference in the reported secondary outcomes of neonatal hypoglycaemia, admission to neonatal nursery, admission to the neonatal nursery for IUGR (low quality evidence), induction of labour and caesarean section (very low quality evidence). The trial did not address the other outcomes specified in the 'Summary of findings' table (intrauterine death; neurodevelopmental outcome in childhood). GRADEpro software was used to assess the quality of evidence, downgrading of evidence was based on including a small single study with unclear risk of bias and a wide confidence interval crossing the line of no effect.

AUTHORS' CONCLUSIONS: There is insufficient evidence to determine whether SFH measurement is effective in detecting IUGR. We cannot therefore recommended any change of current practice. Further trials are needed.

PMID: 14556339

A case of spontaneous rupture of uterine artery in the second trimester of pregnancy is described. Haemorrhage from rupture of uterine artery during pregnancy was discovered at laparotomy. This was an unusual but serious complication of pregnancy. This condition is extremely rare and one must consider it in cases of incomprehensible abdominal pain with or without haemodynamic collapse. A review of the literature revealed only four similar cases so far. This pregnancy continued till 37 weeks pregnancy and had a spontaneous vaginal delivery. Immediate institution of effective resuscitative measures and early surgical intervention were essential to both foetal and maternal survival.

Automated detection of premature delivery using empirical mode and wavelet packet decomposition techniques with uterine electromyogram signals

Acharya UR, Sudarshan VK, Rong SQ, Tan Z, Lim CM, Koh JE, et al.

Comput Biol Med, 2017 06 01;85:33-42.

PMID: 28433870 DOI: 10.1016/j.compbiomed.2017.04.013

An accurate detection of preterm labor and the risk of preterm delivery before 37 weeks of gestational age is crucial to increase the chance of survival rate for both mother and the infant. Thus, the uterine contractions measured using uterine electromyogram (EMG) or electro hysterogram (EHG) need to have high sensitivity in the detection of true preterm labor signs. However, visual observation and manual interpretation of EHG signals at the time of emergency situation may lead to errors. Therefore, the employment of computer-based approaches can assist in fast and accurate detection during the emergency situation. This work proposes a novel algorithm using empirical mode decomposition (EMD) combined with wavelet packet decomposition (WPD), for automated prediction of pregnant women going to have premature delivery by using uterine EMG signals. The EMD is performed up to 11 levels on the normal and preterm EHG signals to obtain the different intrinsic mode functions (IMFs). These IMFs are further subjected to 6 levels of WPD and from the obtained coefficients, eight different features are extracted. From these extracted features, only the significant features are selected using particle swarm optimization (PSO) method and selected features are ranked by Bhattacharyya technique. All the ranked features are fed to support vector machine (SVM) classifier for automated differentiation and achieved an accuracy of 96.25%, sensitivity of 95.08%, and specificity of 97.33% using only ten EHG signal features. Our proposed algorithm can be used in gynecology departments of hospitals to predict the preterm or normal delivery of pregnant women.

Uterotrophic, fetotoxic and abortifacient effect of a Malaysian variety of Plumbago rosea L. on isolated rat uterus and pregnant mice

Abdul Sattar M, Abdullah NA, Khan MA, Dewa A, Samshia D

Pak J Biol Sci, 2007 Mar 01;10(5):763-7.

PMID: 19069860

Traditionally Plumbago rosea L. is used as an abortifacient in the Southeast Asian region. Methanolic root extract of a local species of Plumbago rosea L. was studied to evaluate its traditional antifertility claim. Interestingly, it was found to possess dose related inhibitory effect on uterine contractile responses elicited by oxytocic agents on isolated uteri of pregnant and pseudo-pregnant rats. Furthermore, it was found to possess significant (p < 0.05) fetotoxic activity along with mild abortive potential in pregnant mice when given orally at high doses (400 and 800 mg kg(-1)) once daily for ten days starting from day 10 of gestation. The results derived indicated possible presence of utero-active compound (s) in this plant that inhibited oxytocic agents induced uterine motility. Moreover, pronounced fetotoxic and mild abortifacient potentials observed at higher doses in pregnant mice might support its accredited traditional use to avoid unwanted pregnancy.

BMC Complement Med Ther, 2020 Feb 05;20(1):31.

PMID: 32024514 DOI: 10.1186/s12906-020-2814-z

BACKGROUND: Each year 1.5 million women experience menopause when menstrual cycles cease resulting from the loss of ovarian function and oestrogen deprivation, a hormone that helps prevent bone loss. This study investigated the effects of Physta®, a standardized herbal extract of Eurycoma longifolia Jack (PEL), on hormonal balance and parameters associated with hormonal imbalance, namely body and uterus weight and bone biochemical markers relevant in menopausal symptoms.

METHODS: Forty-eight Sprague Dawley rats were randomly divided into six groups of eight rats each: (A) Sham operated; control (B) Untreated (ovariectomised (OVX) with vehicle), (C) PEL 100 (OVX + 100 mg/kg body weight (bw)), (D) PEL 300 (OVX + 300 mg/kg bw), (E) PEL 500 (OVX + 500 mg/kg bw) and (F) Positive control, testosterone undecanoate (TU) (OVX+ 10 mg/kg bw). Group A and B received daily oral administrations of the vehicle, Group C-E received daily oral administration of PEL and Group F received testosterone undecanoate intramuscularly weekly. At the end of 8 weeks, serum calcium, phosphate, bone alkaline phosphatase (BALP), osteocalcin, follicle stimulating hormone (FSH), luteinising hormone (LH), oestrogen, progesterone and testosterone were measured, then the animals were sacrificed and uterus was isolated, while weight was recorded in all experimental groups.

RESULTS: Treatment of OVX rats with PEL at a dose of 500 mg/kg showed decreased serum FSH (P

Evaluation of copper-7 intrauterine device in Malaysian women

Sivanesaratnam V, Puvan IS, Sinnathuray TA

Med J Aust, 1975 Aug 23;2(8):298-301.

PMID: 1165736

A study of 300 Malaysian women who were fitted with the Copper-7 intrauterine device is presented. Two per cent of the acceptors were nulliparous. Insertion was easy in 97-7% of the cases and the side effects were minimal. In a study of over 4,634 women-months a low cumulative expulsion rate, at 12 and 24 months of use, of 3-1 and 3-6 respectively, was observed. However, relatively high cumulative rates of pregnancy of 4-3 and 9-2 occurred at 12 and 24 months of use respectively. Out of a total of 19 pregnancies, in 12 cases the device was found to have descended, a finding not commonly reported. One woman experienced translocation of the device five months after insertion, and in this instance, the device was removed by laparotomy. The findings in this study and their implications are discussed.
