    PMID: 16018776
    To ascertain the characteristics, clinical features, and maternal fetal outcome in eclampsia in a tertiary referral center with 24 000 deliveries per year.
  2. Comparison of maternal-fetal outcomes in gestational diabetes and lesser degrees of glucose intolerance
    Nordin NM, Wei JW, Naing NN, Symonds EM
    J Obstet Gynaecol Res, 2006 Feb;32(1):107-14.
    PMID: 16445535 DOI: 10.1111/j.1447-0756.2006.00360.x
    AIM: To determine the relationships between maternal and fetal outcomes and gestational diabetes mellitus (GDM), impaired fasting glucose (IFG) and impaired glucose tolerance (IGT), respectively.
    METHODS: A retrospective cohort study design was used with 149 patients with abnormal oral glucose tolerance test (OGTT) and 149 normal patients. Statistical analysis used was the chi-squared test, Fisher's exact test or the Student's t-test, as appropriate. P < 0.05 was considered significant.
    RESULTS: The level of hyperglycemia according to the OGTT (World Health Organization criteria) was associated with pre-eclampsia, polyhydramnios and macrosomia in GDM patients. There was no increase in the complications of preterm labor and premature rupture of membranes, despite the increased risk of polyhydramnios. Although treated with insulin, macrosomia still occurred in patients with GDM, but there was no shoulder dystocia as there was an increase in the incidence of cesarean section (CS). The IGT group was not associated with adverse fetal or maternal outcomes, but there was an increase in intervention and the incidence of CS. The IFG group was associated with a significantly increased risk of pre-eclampsia and macrosomia. These findings challenge the concept of IFG being a lesser pathology than GDM. Further prospective studies with a larger number of patients are needed to ascertain the significance of these findings.
    CONCLUSION: There was an increased risk of pre-eclampsia and macrosomia in both the GDM and IFG patients, but IGT was not associated with adverse fetal or maternal outcomes.

  3. Thrombophilic mutations in pre-eclampsia and pregnancy-induced hypertension
    Omar SZ, Qvist R, Khaing SL, Muniandy S, Bhalla S
    J Obstet Gynaecol Res, 2008 Apr;34(2):174-8.
    PMID: 18412778 DOI: 10.1111/j.1447-0756.2008.00755.x
    The aim of the present study was to determine the existence or prevalence of thrombophilic markers such as Factor V Leiden, prothrombin G20210A, protein S, protein C, activated protein C and anti-thrombin in pre-eclampsia and pregnancy-induced hypertensive patients.
  4. A questionnaire study on disparity of cervical cancer prevention programs in Asia-Oceania
    Oncology Committee, Asia and Oceania Federation of Obstetrics and Gynecology, Tse KY, Ushijima K, Tan AL, Intasorn P, Pariyar J, et al.
    J Obstet Gynaecol Res, 2023 Apr;49(4):1230-1243.
    PMID: 36726190 DOI: 10.1111/jog.15566
    BACKGROUND: Despite the introduction of cervical cancer screening and human papillomavirus (HPV) vaccines, the utilization pattern was not standardized. The aim of this study was to elicit the current prevention care in Asia-Oceania.

    METHODS: An online questionnaire was circulated to different countries/cities in Asia-Oceania. The primary objective was to evaluate the coverage of HPV vaccination and cervical screening programs. The secondary objectives were to study the structures of these programs. Five case scenarios were set to understand how the respondents manage the abnormal screening results.

    RESULTS: Fourteen respondents from 10 countries/cities had participated. Cervical cancer ranked the first in Myanmar and Nepal. About 10%-15% did not have national vaccination or screening program. The estimated coverage rate for vaccination and screening varied from less than 1% to 70%, which the coverage ran in parallel with the incidence and mortality rates of cervical cancer. All regions approved HPV vaccines, although only four provided free or subsidized programs for nonavalent vaccine. Cervical cytology remained the most common screening tool, and 20%-30% relied heavily on visual inspection using acetic acid. The screening age groups varied in different regions. From the case scenarios, it was noted that some respondents tended to offer more frequent screening tests or colposcopy than recommended by international guidelines.

    CONCLUSION: This study revealed discrepancy in the practice of cervical cancer prevention in Asia-Oceania especially access to HPV vaccines. There is an urgent need for a global collaboration to eliminate cervical cancer by public education, reforming services, and medical training.

  5. Strangulated small bowel 14 years after abdominal sacrocolpopexy
    Pue LB, Lo TS, Wu PY, Tan YL
    J Obstet Gynaecol Res, 2014 Feb;40(2):611-3.
    PMID: 24245849 DOI: 10.1111/jog.12174
    Abdominal sacrocolpopexy is a well-established procedure for the reconstruction of apical support in pelvic organ prolapse. Its long-term efficacy is well known; however, it is also associated with higher perioperative morbidity when compared with the less invasive transvaginal approach. Long-term risk of bowel-related complication from abdominal sacrocolpopexy is rare, but can be significant as it is often serious and requires major surgical intervention. Here we highlight an unusual case of strangulated small bowel (in this instance complicated with sepsis secondary to peritonitis), 14 years after an abdominal sacrocolpopexy procedure. This example amplifies the need for proper preoperative counseling; also, life-long follow-up is necessary for patients undergoing this procedure.
  6. Prenatal diagnosis of an extensive haemangioma of the fetal leg: a case report
    Raman S, Ramanujam T, Lim CT
    J Obstet Gynaecol Res, 1996 Aug;22(4):375-8.
    PMID: 8870422
    Extensive haemangioma with platelet consumption (Kasabach-Merritt syndrome) is rare. The lesion is usually a single cutaneous cavernous haemangioma similar to that found in our patient. Multiple superficial strawberry naevi were also seen all over the rest of the body. This condition was diagnosed antenatally in this patient with the use of colour Doppler. There is one recent report where the thrombocytopaenia was diagnosed by cordocentesis. Unfortunately the baby developed heart failure with intractable coagulopathy and died 2 days later.
  7. Dysmenorrhea in young people: Experiences from a tertiary center with a focus on conservative management
    Sachedina A, Abu Bakar M, Dunford AM, Morris A, Nur Azurah AG, Grover SR
    J Obstet Gynaecol Res, 2021 Jan;47(1):352-358.
    PMID: 33084069 DOI: 10.1111/jog.14532
    AIM: To describe the characteristics, management and outcomes of a cohort of young people with dysmenorrhea presenting to a tertiary adolescent gynecology service, managed primarily with medical interventions.

    METHODS: A retrospective cohort study was conducted at the Royal Children's Hospital in Melbourne, Australia. Data were collected from medical records of patients presenting with dysmenorrhea and/or pelvic pain.

    RESULTS: Of 154 patients, mean age of presentation was 15.7 years (SD = 2.2) and mean duration of pain was 14.9 months (SD = 10.8). Regular cycles were reported by 64.5%, and heavy menstrual bleeding (HMB) in 67.8%. Patients self-reporting HMB reported less pain on the day prior to menses than those not reporting HMB (P

  8. Third S. S. Ratnam memorial lecture 2007. Ovarian cancer: Is there hope for women?
    Sivanesaratnam V
    J Obstet Gynaecol Res, 2009 Jun;35(3):393-404.
    PMID: 19527374 DOI: 10.1111/j.1447-0756.2009.01049.x
    Ovarian cancer is today the most lethal female cancer with an overall survival of only 49.9%. The currently available screening modalities are disappointing in detecting highly curable early stage ovarian cancer. Natural history of ovarian cancer is unknown; it appears it can develop quickly from normal looking ovaries. Timely referral of women with non-specific symptoms (such as abdominal bloating, pelvic pain) for an ultrasound scan or blood CA125 assessments may help in the early diagnosis. Patients with Stage IA or IB disease with grade 1 tumors have a cure rate of >90%; this is likely to be compromised by laparoscopic surgery. In selected patients fertility preservation with good obstetric outcome is possible. However, the relapse rate in 'high risk' early stage ovarian cancers is 40-45%; adjuvant chemotherapy is needed. Only 20-25% of those with stage III and IV disease are cured. Despite a high primary response (70%) majority (70-75%) will relapse and all are likely to succumb. Optimal debulking surgery followed by adjuvant chemotherapy are needed for stages III and IV disease; the outcome is superior if managed by gynecologic oncologists. Where cost of drugs is an important consideration, an alternative is carboplatin (an affordable and equally effective drug). The role of vaccines needs further study. When relapses occur palliation will be the aim in most instances. Oral contraceptives, breast feeding, tubal sterilization and hysterectomy also have a protective effect. Risk-reducing salpingo-oopherectomy has been suggested in women with BRCA mutations.
  9. Chien-Tien Hsu Memorial Lecture. Fertility and gynaecologic malignancies
    Sivanesaratnam V
    J Obstet Gynaecol Res, 2001 Feb;27(1):1-15.
    PMID: 11330724
    Fertility and gynaecological malignancies have an important relationship. A clear inverse relationship exists between family size and the incidence of ovarian and endometrial cancer. Current methods of fertility control have an influence on subsequent development of various gynaecological malignancies. A slightly increased risk of breast cancer has been reported in current users and those who had used hormonal contraceptives (OCs) within 10 years; this risk declined with time and disappeared after 10 years. Women who started OC before age 20 had a higher relative risk; the disease did not spread beyond the breast in the majority. Most studies found OC to reduce the risk of ovarian and endometrial cancer. The relative risks of squamous cell carcinoma and adenomatous carcinoma of the cervix have been reported to be 1.3 and 1.5, respectively in ever-users of OCs; however, the aetiology of cervical cancer is multifactoral. Several reports suggest the beneficial effect of tubal ligation and breast feeding in reducing the risk of ovarian cancer. Therapy of gynaecological malignancies may have an influence on subsequent fertility. Amenorrhoea developing after treatment of hydatidiform mole may be due to choriocarcinoma, recurrent mole or a normal pregnancy. Choriocarcinoma can also develop after a partial mole. The risk of fetal teratogenicity from chemotherapy is present only if conception occurs during or immediately following the treatment cycles. Fertility is not impaired following chemotherapy. Successful pregnancies have occurred in women who have had widespread GTD including cerebral metastases. In the young patient with gynaecological malignancy preservation of fertility is possible. Fertility-sparing surgery may be safe in early ovarian epithelial cancers and even in advanced germ cell tumours. Recently, the fertility-sparing surgery of radical trachelectomy and pelvic lymphadenectomy has been carried out for early invasive cervical cancer in young women. Gynaecological cancer occurring in pregnancy is uncommon; it presents the clinician with a difficult situation to manage. In most instances the cancer is treated as though the patient is not pregnant; the timing and mode of delivery needs individualization. The overall prognosis for breast cancer complicating pregnancy is poor. Survival in cervical cancers diagnosed antepartum is similar to the non-pregnant patient. Ovarian cancer in pregnancy has a good prognosis because of the early stage at diagnosis.
  10. Umbilical artery resistance index in diabetic pregnancies: the associations with fetal outcome and neonatal septal hypertrophic cardiomyopathy
    Tan AE, Norizah WM, Rahman HA, Aziz BA, Cheah FC
    J Obstet Gynaecol Res, 2005 Aug;31(4):296-301.
    PMID: 16018775 DOI: 10.1111/j.1447-0756.2005.00291.x
    Aim: To determine the incidence of an abnormal umbilical artery resistance index (UARI) in diabetic pregnancies and the relation to fetal outcome and the development of neonatal septal hypertrophic cardiomyopathy.

    Methods: A case-control study with subjects comprising 50 randomly selected diabetic mothers and a matched control group of 50 non-diabetic pregnancies. Doppler studies of the UARI were carried out at least once per week, beginning from 36 weeks' gestation for both groups. Within 48 h post delivery, echocardiograms were carried out on the newborn infants to identify those with hypertrophic cardiomyopathy, particularly asymmetrical septal hypertrophy.

    Results: The numbers of patients with abnormal UARI were similar in both the diabetic and control groups. A higher proportion of operative deliveries for intrapartum fetal distress was seen in patients with an abnormal UARI in the diabetic group. However, the groups did not differ in the numbers of infants who were small for gestational age, who had low Apgar scores or umbilical artery acidosis, and who required admission to the special care nursery. Six infants of diabetic mothers (12%) had septal hypertrophy, but none of these were associated with abnormal antenatal UARI.

    Conclusion: Diabetic pregnancy is not associated with a significantly higher incidence of abnormal UARI on Doppler study than non-diabetic pregnancy. UARI is not a useful single indicator by which to predict subsequent fetal outcome or the development of neonatal septal hypertrophic cardiomyopathy in diabetic pregnancies.
  11. Unusual form of superficial spreading microinvasive squamous cell carcinoma of uterine cervix involving the endometrium of uterus
    Tan GC, Isa MR, Ng SP, Jamil YM
    J Obstet Gynaecol Res, 2004 Oct;30(5):363-7.
    PMID: 15327449
    Microinvasive squamous cell carcinoma of the uterine cervix is a recognized entity and is defined as carcinoma with invasion of less than 5 mm penetration of the stroma and seldom metastasized. Our patient was a 70-year-old, multiparous woman who had a microinvasive, cervical, squamous cell carcinoma. The tumor had spread superficially into the entire endometrial cavity up to the fundus, totally replacing the columnar epithelium. This is an extremely rare phenomenon, with fewer than 20 cases reported so far in the literature.
  12. Evaluation of the efficacy of constitutional array-based comparative genomic hybridization in the diagnosis of aneuploidy using genomic and amplified DNA
    Tan NH, Palmer R, Wang R
    J Obstet Gynaecol Res, 2010 Feb;36(1):19-26.
    PMID: 20178523 DOI: 10.1111/j.1447-0756.2009.01110.x
    Array-based comparative genomic hybridization (array CGH) is a new molecular technique that has the potential to revolutionize cytogenetics. However, use of high resolution array CGH in the clinical setting is plagued by the problem of widespread copy number variations (CNV) in the human genome. Constitutional microarray, containing only clones that interrogate regions of known constitutional syndromes, may circumvent the dilemma of detecting CNV of unknown clinical significance.
  13. Screening for urinary tract infection in women with hyperemesis gravidarum
    Tan PC, King AS, Omar SZ
    J Obstet Gynaecol Res, 2012 Jan;38(1):145-53.
    PMID: 21955280 DOI: 10.1111/j.1447-0756.2011.01652.x
    AIM: The aim of this study was to evaluate urine microscopy, dipstick analysis and urinary symptoms in screening for urinary tract infection (UTI) in hyperemesis gravidarum (HG).
    MATERIALS AND METHODS:   A prospective cross-sectional study was performed on women at first hospitalization for HG. A clean-catch mid-stream urine sample from each recruit was sent for microscopy (for bacteria, leucocytes and erythrocytes), dipstick analysis (for leukocyte esterase, nitrites, protein and hemoglobin) and microbiological culture. The presence of current urinary symptoms was elicited by questionnaire. UTI is defined as at least 10(5) colony-forming units/mL of a single uropathogen on culture. Screening test parameters were analyzed against UTI.
    RESULTS: UTI was diagnosed in 15/292 subjects (5.1%). Receiver-operator characteristic curve analysis of microscopic urine leucocytes revealed area under the curve=0.64, 95% confidence interval (CI) 0.5-0.79, P=0.063 and erythrocytes area under the curve=0.53, 95%CI 0.39-0.67, P=0.67 for UTI indicating the limited screening utility of these parameters. Microscopic bacteriuria (likelihood ratio [LR] 1.1, 95%CI 0.7-1.5) and urine dipstick leukocyte esterase (LR 1.4, 95%CI 1.1-1.8), nitrites (LR 2.3, 95%CI 0.3-17.2), protein (LR 1.0, 95%CI 0.7-1.6) and hemoglobin (LR 0.8, 95%CI 0.4-1.5) were not useful screening tests for UTI in HG. Elicited symptoms were also not predictive of UTI.
    CONCLUSION: Urine microscopy, dipstick analysis and urinary symptoms were not useful in screening for UTI in HG. UTI should be established by urine culture in HG before starting antibiotic treatment.
  14. Gamma-glutamyltransferase level in pregnancy is an independent risk factor for gestational diabetes mellitus
    Tan PC, Mubarak S, Omar SZ
    J Obstet Gynaecol Res, 2008 Aug;34(4):512-7.
    PMID: 18937705 DOI: 10.1111/j.1447-0756.2008.00815.x
    AIM:
    To evaluate the relationship between gamma-glutamyltransferase (GGT) level in pregnant women at oral glucose tolerance test (OGTT) and the diagnosis of gestational diabetes (GDM).

    METHODS:
    Blood was taken for analyzing GGT level from women at high risk of GDM at the time of their scheduled OGTT. GDM was diagnosed according to World Health Organization 1999 criteria.

    RESULTS:
    GGT level correlated positively with the 2-hour glucose level (Spearman's rho = 0.112: P < 0.05). GGT values that were stratified into quartiles demonstrated a significant trend with diagnosis of GDM (chi(2) for trend; P = 0.03). Multivariable logistic regression analysis taking into account maternal age, gestational age at OGTT, body mass index and a positive 50-g glucose challenge test (GCT) indicated that high GGT was an independent risk factor for GDM (adjusted odds ratio [AOR] 2.1 95% CI 1.2-3.8: P = 0.01). In the subset of women identified by a positive GCT, on multivariable logistic regression analysis, only high GGT was an independent risk factor for GDM (AOR 2.3 95% CI 1.3-4.2: P = 0.007).

    CONCLUSION:
    Raised GGT level is an independent risk factor for GDM in high risk pregnant women undergoing OGTT.
  15. Pregnancy outcome in hyperemesis gravidarum and the effect of laboratory clinical indicators of hyperemesis severity

    J Obstet Gynaecol Res, 2007 Aug;33(4):457-64.
    PMID: 17688612
    To determine pregnancy outcome in hyperemesis gravidarum and the effect of metabolic, biochemical, hematological and clinical indicators of disease severity on outcome.
  16. Rare postpartum ruptured degenerated fibroid: a case report
    Tan YL, Naidu A
    J Obstet Gynaecol Res, 2014 May;40(5):1423-5.
    PMID: 24689652 DOI: 10.1111/jog.12334
    Spontaneous rupture of uterine fibroid is rarely encountered. We present a case of a 31-year-old who presented with acute abdominal pain at 9 weeks postpartum. On examination, the abdomen had diffuse tenderness, with rebound tenderness in the suprapubic area and in both iliac fossae. On ultrasonography, a 12.7 × 8.6 × 8.9-cm sized hyperechoic mass was visible on the posterior wall of the uterus. A large amount of fluid was visible in the paracolic gutters and the Pouch of Douglas (POD). The patient underwent an exploratory laparotomy. A ruptured, cystic degenerated uterine fibroid with active bleeding was found, as well as approximately half a liter of free, bloodstained peritoneal fluid and pus. Myomectomy was performed, followed by evacuation of the fluid and clots. The patient's postoperative course was uneventful. In conclusion, preoperative diagnosis of a perforated, uterine fibroid with spontaneous intra-abdominal hemorrhage is difficult; exploratory laparotomy is both diagnostic and therapeutic in this rare, life-threatening condition.
  17. Outcome of external cephalic version: our experience
    Teoh T
    J Obstet Gynaecol Res, 1996 Aug;22(4):389-94.
    PMID: 8870425
    The aim is to assess the outcome of external cephalic version (ECV) for term breech in our clinical setting and the factors involved. Patients with no contraindications and who consented to ECV were recruited into this prospective study. Terbutalin infusion was used. There were 42 ECV attempts of which 21 (50%) were successful. Seventeen of the patients with successful ECV delivered vaginally and 4 had cesarean section for various indications. Only 5 of the 21 unsuccessful ECV delivered vaginally. Thirteen had elective cesarean section and 2 had emergency cesarean during trial of breech. One patient from the unsuccessful ECV group was lost to follow-up. There were 31 (74%) primipara. The birth weight of the babies was not a significant factor in the outcome of ECV. The type of breech and parity did influence the success rate. External cephalic version should be included in the routine management of our breech presentation.
  18. Fulltext COVID-19 and gynecological cancers: Asia and Oceania Federation of Obstetrics and Gynecology oncology committee opinion
    Tse KY, Domingo EJ, Konar H, Kumarasamy S, Pariyar J, Tjokroprawiro BA, et al.
    J Obstet Gynaecol Res, 2021 May;47(5):1643-1650.
    PMID: 33650217 DOI: 10.1111/jog.14579
    Since the outbreak of COVID-19, there have already been over 26 million people being infected and it is expected that the pandemic will not end in near future. Not only the daily activities and lifestyles of individuals have been affected, the medical practice has also been modified to cope with this emergency catastrophe. In particular, the cancer services have faced an unprecedented challenge. While the services may have been cut by the national authorities or hospitals due to shortage of manpower and resources, the medical need of cancer patients has increased. Cancer patients who are receiving active treatment may develop various kinds of complications especially immunosuppression from chemotherapy, and they and their carers will need additional protection against COVID-19. Besides, there is also evidence that cancer patients are more prone to deteriorate from COVID-19 if they contract the viral infection. Therefore, it is crucial to establish guidelines so that healthcare providers can triage their resources to take care of the most needed patients, reduce less important hospitalization and visit, and to avoid potential complications from treatment. The Asia and Oceania Federation of Obstetrics and Gynecology (AOFOG) hereby issued this opinion statement on the management of gynecological cancer patients during the COVID-19.
  19. α-thalassemia-associated hydrops fetalis: A rare cause of thyrotoxic cardiomyopathy
    Tumian NR, Wong M, Wong CL
    J Obstet Gynaecol Res, 2015 Jun;41(6):967-70.
    PMID: 25510540 DOI: 10.1111/jog.12648
    α°-thalassemia is a well-known cause of hydrops fetalis in South-East Asia and can be detected in utero. We report a very rare case of thyrotoxic cardiomyopathy associated with hyperplacentosis secondary to α°-thalassemia-associated hydrops fetalis. A 22-year-old primigravida with microcytic anemia presented at 27 weeks' gestation with pre-eclampsia, hyperthyroidism and cardiac failure. Serum β-human chorionic gonadotrophin was markedly elevated and abdominal ultrasound revealed severe hydropic features and enlarged placenta. Serum β-human chorionic gonadotrophin, cardiac function and thyroid function tests normalized after she delivered a macerated stillbirth. Histopathology of the placenta showed hyperplacentosis. Blood DNA analysis revealed that both patient and husband have the α°-thalassemia trait. This case illustrates a very atypical presentation of α°-thalassemia-associated hydrops fetalis and the importance of early prenatal diagnosis of α-thalassemia in women of relevant ethnic origin with microcytic anemia so that appropriate genetic counseling can be provided to reduce maternal morbidity and the incidence of hydrops fetalis.
  20. Management of bleeding irregularities among etonogestrel implant users: Is combined oral contraceptives pills or nonsteroidal anti-inflammatory drugs the better option?
    Upawi SN, Ahmad MF, Abu MA, Ahmad S
    J Obstet Gynaecol Res, 2020 Mar;46(3):479-484.
    PMID: 31958877 DOI: 10.1111/jog.14195
    AIM: This study is to evaluate whether unacceptable bleeding among the etonogestrel implant user could be better alleviated using combined oral contraceptive pills (COCP) or nonsteroidal anti-inflammation drugs (NSAID).

    METHODS: This is a prospective randomized study for evaluation of 84 etonogestrel implant (Implanon) users with prolonged or frequent bleeding. They were assigned to either receiving a COCP containing 20 mcg ethinyl estradiol/150 mg desogestrel for two continuous cycle or NSAID; mefenamic acid 500 mg TDS for 5 days, 21 days apart for two cycles. Bleeding pattern during the treatment was recorded and analyzed.

    RESULTS: A total of 32 women (76.2%) in COCP group and 15 women (35.7%) in NSAID group stop bleeding within 7 days after the initiation of treatment which was statistically significant (P
