    OBJECTIVE: To quantify circulating fetal DNA (fDNA) levels in the second and third trimesters of normal healthy pregnant individuals and pregnant women with the following clinical conditions: gestational diabetes mellitus (GDM), iron deficiency anemia and gestational hypertension (GHT).
    METHODS: The SRY gene located on the Y chromosome was used as a unique fetal marker. The fDNA was extracted from maternal plasma and the SRY gene concentrations were measured by quantitative real-time polymerase chain reaction (PCR) amplification using TaqMan dual labeled probe system.
    RESULTS: No significant differences were observed in the mean fDNA concentration between normal and GDM pregnancy samples (p > 0.05) and also between normal and anemic pregnancy samples (p > 0.05) in both trimesters, but significant differences were observed between the third trimester normal and GHT pregnancy samples (p = 0.001). GDM and iron deficiency anemia do not affect the levels of fDNA in maternal plasma while GHT significantly elevates the levels of fDNA in maternal plasma.
    CONCLUSIONS: Increased amount of circulating fDNA in maternal plasma could be used for early identification of adverse pregnancies. GDM and anemia do not affect the levels of fDNA in maternal plasma while GHT significantly elevates the levels of fDNA in maternal plasma. Hence, the elevated fDNA values could be used as a potential screening marker in pregnancies complicated with GHT but not with GDM and iron deficiency anemia.

    Varicella or chickenpox is an infectious disease caused by Varicella Zoster Virus (VZV), which commonly affects the children. It is a mild, self-limiting disease and rarely complicate to serious conditions except in adults. Decreasing incidence of chickenpox among children, probably owing to improved living conditions ,prevention and health care, is worrisome as growing number of adults are being infected. This creates disturbing concerns in many parties as women at childbearing age might get infected and not only are them at a great risk of serious complications, but also their unborn fetus or their newborn babies.

    Gestational breast cancer (GBC) or pregnancy-associated breast cancer was defined as breast cancer diagnosed during pregnancy and within 1 year of delivery. Breast cancer is the second commonest cancer after cervical seen in pregnancy and lactation. Nevertheless, the incidence is low and accounts for approximately 1 in 3000 of pregnancies. A delay in diagnosis is common and 70% to 89% of patients with operable primary lesions already have positive axillary lymph nodes. Breast cancer identified during pregnancy can be extremely distressing for the mother despite it has similar course of disease and prognosis seen in non-pregnant women of the same age and stage of disease. Diagnostic and treatment options should be carefully decided to prevent further harm to the mother or any potential risk to the developing fetus.

    Previous research reported that prolonged benzene exposure during in utero fetal development causes greater fetal abnormalities than in adult-stage exposure. This phenomenon increases the risk for disease development at the fetal stage, particularly carcinogenesis, which is mainly associated with hematological malignancies. Benzene has been reported to potentially act via multiple modes of action that target the hematopoietic stem cell (HSCs) niche, a complex microenvironment in which HSCs and multilineage hematopoietic stem and progenitor cells (HSPCs) reside. Oxidative stress, chromosomal aberration and epigenetic modification are among the known mechanisms mediating benzene-induced genetic and epigenetic modification in fetal stem cells leading to in utero carcinogenesis. Hence, it is crucial to monitor exposure to carcinogenic benzene via environmental, occupational or lifestyle factors among pregnant women. Benzene is a well-known cause of adult leukemia. However, proof of benzene involvement with childhood leukemia remains scarce despite previously reported research linking incidences of hematological disorders and maternal benzene exposure. Furthermore, accumulating evidence has shown that maternal benzene exposure is able to alter the developmental and functional properties of HSPCs, leading to hematological disorders in fetus and children. Since HSPCs are parental blood cells that regulate hematopoiesis during the fetal and adult stages, benzene exposure that targets HSPCs may induce damage to the population and trigger the development of hematological diseases. Therefore, the mechanism of in utero carcinogenicity by benzene in targeting fetal HSPCs is the primary focus of this review.

    The G antigen of Rh blood group system is present in almost all D-positive or C-positive red cells but absent from red cells lacking D and C antigens. The differentiation of anti-D and anti-C from anti-G is not necessary for routine transfusion; however, during pregnancy, it is important because anti-G can masquerade as anti-D and anti-C with initial antibody testing. The false presence of anti-D will exclude the patient from receiving anti-D immunoglobulin (RhIG) when the patient actually is a candidate for RhIG prophylaxis. Moreover, patients with positive anti-D or anti-G are at risk of developing hemolytic disease of the fetus and newborn and need close monitoring. Thus, proper identification allows the clinicians to manage patients properly. This case report highlights a rare case of anti-G together with anti-D and anti-C in a pregnant woman. This report disseminates knowledge on identification of anti-G and its importance in pregnant women.

    A systematic collection of fetal morphometric measurements was started seven years ago in 1987 with the prospective entry of data into personal computer-based stations in the Department of Obstetrics and Gynaecology, Singapore General Hospital. A cross-sectional study was done, comparing 2392 Chinese fetuses with 2117 Malay fetuses and 459 Indian fetuses from 18 to 40 weeks. The mean values of the head circumference (HC), abdominal circumference (AC) and femur length (FL) of the 3 ethnic groups were analysed. There were no statistical significant differences in the head circumference and abdominal circumference of Chinese, Malay and Indian fetuses in Singapore. The Chinese and Malay fetal femur length appeared similar but were apparently shorter than the Indian femur length. Nomograms of head circumference, abdominal circumference and femur length were constructed for application to fetuses of all 3 ethnic groups.

    OBJECTIVE: To evaluate the association between intrauterine growth restriction (IUGR) and the incidence of fetuses with patent ductus arteriosus (PDA) and Hemodynamically significant PDA (Hs-PDA) in dichorionic twins (DC) with selective IUGR.

    MATERIALS AND METHODS: This is an observational cohort study and retrospective case assessment, involved twins born at Linkou Chang Gung Memorial Hospital, Taoyuan, Taiwan between 2013 and 2018. DC twins with selective IUGR (sIUGR) were defined as the presence of a birth weight discordance of >25% and a smaller twin with a birth weight below the tenth percentile. PDA was diagnosed using echocardiography between postnatal day 3 and 7. Hs-PDA was defined as PDA plus increased pulmonary circulation, poor systemic perfusion, cardiomegaly, pulmonary edema, or hypotension requiring pharmacotherapeutic intervention.

    RESULT: A total of 1187 twins were delivered during the study period, and 53 DC twins with selective IUGR were included in this study. DC twins with PDA have higher rate of preterm birth, lower gestational age of delivery, and lower mean birth weight of both twins compared with DC twins without PDA. In a comparison of the sIUGR twin with the appropriate for gestational age co-twin, both the incidences of PDA (28.30% vs. 7.55%, respectively; P = 0.003) and Hs-PDA (24.53% vs. 5.66%, respectively; P = 0.002) were higher in sIUGR fetuses than in the appropriate for gestational age co-twins. Small gestational age of delivery was the only variable to predict PDA and Hs-PDA [p = 0.002, Odds ratio = 0.57 (0.39-0.82), p = 0.009, Odds ratio = 0.71 (0.55-0.92), respectively].

    CONCLUSION: An analysis of dichorionic twins with sIUGR indicated that IUGR increased the risk of PDA and hemodynamically significant PDA.

    Fetus-in-fetu (FIF) is a rare entity in which malformed parasitic twin grows inside the body of its twin. It is most commonly presented with mass in the abdomen. We present a case of a 15-year-old boy who presented with abdominal mass since infancy. Radiological investigations are suggestive of FIF. Intraoperatively, malformed fetus in a sac was found and excised. Postoperatively the patient recovers well and was put on follow-up.

    Hemoglobin disorders which include thalassemias are the most common heritable disorders. Effective treatment is available, and these disorders can be avoided as identification of carriers is achievable using simple hematological tests. An in-depth understanding of the awareness, attitudes, perceptions, and screening reservations towards thalassemia is necessary, as Malaysia has a multi-ethnic population with different religious beliefs. A total of 13 focus group discussions (70 participants) with members of the general lay public were conducted between November 2008 and January 2009. Lack of knowledge and understanding about thalassemia leads to general confusions over differences between thalassemia carriers and thalassemia major, inheritance patterns, and the physical and psychologically impact of the disorder in affected individuals and their families. Although most of the participants have not been tested for thalassemia, a large majority expressed willingness to be screened. Views on prenatal diagnosis and termination of fetuses with thalassemia major received mixed opinions from participants with different religions and practices. Perceived stigma and discrimination attached to being a carrier emerged as a vital topic in some group discussions where disparity in the answers exhibited differences in levels of participants' literacy and ethnic origins. The two most common needs identified from the discussion were information and screening facilities. Participants' interest in knowing the severity of the disease and assessing their risk of getting the disorder may imply the health belief model as a possible means of predicting thalassemia public screening services. Findings provide valuable insights for the development of more effective educational, screening, and prenatal diagnostic services in the multi-ethnic Asian society.

    BACKGROUND: The placenta is a most interesting but unfortunately often ignored and misunderstood organ. Placental abnormalities, therefore, can be an "early warning system" for fetal problems. A complete prenatal sonographic examination of the placenta is an essential component as its abnormalities can have a direct effect on fetal or maternal outcomes, obstetrical management and future fertility.

    OBJECTIVE: To determine whether any association exists between the finding of an increased thickness of placenta, abnormal placenta shape, placental calcification, placental lake and abnormal cord insertion site at 20-22 and 30-32 weeks gestation with an increased risk of uteroplacental complications or a poor pregnancy outcome.

    METHODOLOGY: A real-time ultrasound was used at the time of detail scan (at 20-22 weeks gestation) and at 30-32 weeks gestation to look for placenta appearance, fetal growth and anomaly. The main outcome measures were risk of hypertension disease in pregnancy, fetal growth restriction and poor fetal outcomes such as low Apgar score and low cord pH.

    RESULT: The majority of the participants were Malay (77.9%). Abnormal placenta found at both gestations were placental lakes and thickness, and only one case had marginal cord insertion. Approximately 6% of the cases were confirmed placenta previa. No abnormal shape or abnormal calcification found at both gestations. About 10% patient developed hypertensive disease in pregnancy, 15% of the fetus was found to have growth restriction and another 16% have low umbilical cord pH. Majority of them delivered at term (90%) and via vaginal delivery (81%). There was no significance between presence of abnormal placental lake and thickness at both gestations with the maternal and fetal outcome.

    CONCLUSION: Presence of abnormal placental thickness and lakes at 30-32 weeks scan associated with maternal hypertensive disease, fetal growth restriction and low umbilical cord pH, however these were not statistically significant.

    Background: Gemcitabine (GEM) is a chemotherapeutic agent, which is known to battle cancer but challenging due to its hydrophilic nature. Nanoemulsion is water-in-oil (W/O) nanoemulsion shows potential as a carrier system in delivering gemcitabine to the cancer cell.

    Methods: The behaviour of GEM in MCT/surfactants/NaCl systems was studied in the ternary system at different ratios of Tween 80 and Span 80. The system with surfactant ratio 3:7 of Tween 80 and Span 80 was chosen for further study on the preparation of nanoemulsion formulation due to the highest isotropic region. Based on the selected ternary phase diagram, a composition of F1 was chosen and used for optimization by using the D-optimal mixture design. The interaction variables between medium chain triglyceride (MCT), surfactant mixture Tween 80: Span 80 (ratio 3:7), 0.9 % sodium chloride solution and gemcitabine were evaluated towards particle size as a response.

    Results: The results showed that NaCl solution and GEM gave more effects on particle size, polydispersity index and zeta potential of 141.57±0.05 nm, 0.168 and -37.10 mV, respectively. The optimized nanoemulsion showed good stability (no phase separation) against centrifugation test and storage at three different temperatures. The in vitro release of gemcitabine at different pH buffer solution was evaluated. The results showed the release of GEM in buffer pH 6.5 (45.19%) was higher than GEM in buffer pH 7.4 (13.62%). The cytotoxicity study showed that the optimized nanoemulsion containing GEM induced cytotoxicity towards A549 cell and at the same time reduced cytotoxicity towards MRC5 when compared to the control (GEM solution).

    We illustrate a case of giant placental chorioangioma presenting at 20 weeks of gestation. Subsequent monitoring revealed enlargement of the lesion, associated with fetal anemia and cardiac failure, prompting in utero intervention. Amnioreduction followed by percutaneous embolization of the tumour with enbucrilate:Lipiodol Ultra-Fluid™ at a dilution of 1:5 was successfully performed. No repeat intervention or additional supportive measures were required throughout pregnancy and the baby was delivered at 36 weeks of gestation, following spontaneous labour. Due to prolonged neonatal jaundice, further investigations were undertaken, demonstrating subacute right portal vein thrombosis. Other previously reported causes of neonatal portal vein thrombosis such as umbilical vein thrombosis, neonatal umbilical vein catheterization, thrombophilia and sepsis were excluded. There was resolution of the thrombus by 6 months of life. A brief discussion of measures to minimize the risk of such an event and the long-term outcomes of neonatal portal vein thrombosis was included. Whilst the simplicity and efficacy of the procedure has been demonstrated in a handful of patients, judgment on its safety is best deferred. Counselling should be comprehensive, as even rare complications can result in significant postnatal morbidity.

    OBJECTIVE: Maternal allo-antibody production is stimulated when fetal red blood cells are positive for an antigen absent on the mother's red cells. The maternal IgG antibodies produced will pass through the placenta and attack fetal red cells carrying the corresponding antigen. Allo-immune hemolytic disease of the fetus and newborn caused by anti-E rarely occurs.

    CASE SUMMARY: We report two cases of anti-E hemolytic diseases in neonates. One of the neonates had severe hemolysis presenting with severe anemia, thrombocytopenia, and conjugated hyperbilirubinemia, while the other had moderate anemia and unconjugated hyperbilrubinemia. Although both the neonates were treated by phototherapy and intravenous immunoglobulin, one of them received double volume exchange transfusion.

    CONCLUSION: There appeared to be an increase in the occurrence of hemolytic disease of the fetus and newborn caused by Rh antibodies other than anti-D. In this case report, both patients presented with anemia and hyperbilirubinemia but were successfully treated, with a favorable outcome.

    Introduction: Doppler mode ultrasound is widely used in prenatal scanning and known to produce a higher acoustic
    output which later leads to higher heat energy conversion compared to other ultrasound modes. It has been reported
    that the use of Doppler imaging might increase the temperature of tissues, thus, when Doppler is used in combination with 2D ultrasound, the risks of bioeffects tend to increase more. It is also known that prolonged exposure to
    ultrasound during pregnancy can cause irreversible biological destructions to the fetus. Despite the benefits of using
    Doppler ultrasound, its potential adverse effects have received scant attention in the research literature. Therefore,
    this study aimed to examine a correlation between gestational stages (GS) and newborn rabbit’s body weight at different prenatal Doppler ultrasound exposure durations. Methods: Twelve pregnant New Zealand white rabbits (NZWR)
    were exposed once using three different Doppler ultrasound exposure durations (30, 60, 90 minutes exposure) at
    three different GSs (1st, 2nd, and 3rd GS). After delivery, the mean weights of the 62 newborns were statistically analysed. Results: Strong negative and positive correlation between newborn’s body weight at different GSs and Doppler
    ultrasound exposure durations with a significant result found in 60 minutes exposure (p =

    In pregnancy, the diagnosis of primary hyperparathyroidism (PHP) may be delayed due to physiological changes that occur during this period. The maternal related complications of PHP during pregnancy has been reported to be as high as 67%, whilst fetal complications up to 80% of cases.1 The therapeutic gold standard and definitive treatment for PHP in pregnancy is minimally invasive parathyroidectomy in the second trimester. We report a case of a 22-year old primidgravida who underwent parathyroidectomy in the third trimester of her pregnancy for PHP with persistent hypercalcemia. She was also found to have Vitamin D deficiency which probably led to secondary hyperparathyroidism and made her hypercalcemia more apparent during pregnancy

    BACKGROUND: Recombinant Keratinocyte Growth Factor (rHuKGF) is a therapeutic protein used widely in oral mucositis after chemotherapy in various cancers, stimulating lung morphogenesis and gastrointestinal tract cell proliferation. In this research study, chitosan-rHuKGF polymeric complex was implemented to improve the stability of rHuKGF and used as rejuvenation therapy for the treatment of oral mucositis in cancer patients.

    OBJECTIVE: Complexation of rHuKGF with mucoadhesive low molecular weight chitosan to protect rHuKGF from proteolysis and investigate the effect of chitosan-rHuKGF complex on the proliferation rate of FHs 74 Int cells.

    METHODS: The interaction between chitosan and rHuKGF was studied by molecular docking. Malvern ZetaSizer Nano Zs and Fourier-Transform Infrared spectroscopy (FTIR) tests were carried out to characterize the chitosan-rHuKGF complex. In addition, SDS-PAGE was performed to investigate the interaction between chitosan-rHuKGF complex and pepsin. The effect of chitosan-rHuKGF complex on the proliferation rate of FHs 74 Int cells was studied by MTT assay.

    RESULTS: Chitosan-rHuKGF complex was formed through the hydrogen bonding proven by the docking studies. A stable chitosan-rHuKGF complex was formed at pH 4.5 and was protected from proteolysis and assessed by SDS PAGE. According to the MTT assay results, chitosan-rHuKGF complex increased the cell proliferation rate of FHs 74 Int cells.

    CONCLUSION: The developed complex improved the stability and the biological function of rHuKGF.

    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,

    The association between female fetal sex and hyperemesis gravidarum is well established in European and North American populations. The association between female fetuses and severity of hyperemesis remains uncertain. A retrospective study based on case notes review of 166 Asian women hospitalised for hyperemesis was performed. Female fetuses were significantly associated with hyperemesis in our population (P= 0.004, OR 1.6, 95% CI 1.2-2.2) as well as associated with severe ketonuria and high urea. When both severe ketonuria and high urea were present at initial hospital admission for hyperemesis, 83% (95% CI 66-93) of the fetuses were female.

    Tritrichomonas foetus is known to cause chronic diarrhea in the feline species in many different regions of the world. However, there is a paucity of information on T. foetus among cats in Malaysia. This study was conducted to determine the prevalence of Tritrichomonas foetus in the pet and stray cat population in Klang Valley, Malaysia. A total of 201 pet and stray cats' fecal samples were collected in Klang Valley. 24 samples were cultured in the InPouch® TF Feline to observe for motile trophozoites. A nested PCR protocol was used to screen for T. foetus in the collected samples. The prevalence of T. foetus in the cat population in Klang Valley was 33%. There was no association between Tritrichomonas infection and age, sex, breed or management of the cats. However, statistical analysis revealed that stray cats were more likely to be infected with T. foetus compared to pet cats. This study confirmed for the first time the presence of T. foetus among the cat population in Klang Valley, Malaysia.

    Porcine circovirus 3 (PCV3) was first discovered in 2016, almost concomitantly by two groups of researchers in the United States. The novel case was reported in a group of sows with chronic reproductive problems with clinical presentation alike porcine dermatitis and nephropathy syndrome (PDNS), where metagenomic sequencing revealed a genetically divergent porcine circovirus designated PCV3. The discovery of PCV3 in a PDNS case, which used to be considered as part of PCVAD attributed to PCV2 (porcine circovirus 2), has garnered attention and effort in further research of the novel virus. Just when an infectious molecular DNA clone of PCV3 has been developed and successfully used in an in vivo pathogenicity study, yet another novel PCV strain surfaced, designated PCV4 (porcine circovirus 4). So far, PCV3 has been reported in domestic swine population globally at low to moderate prevalence, from almost all sample types including organ tissues, faecal, semen and colostrum samples. PCV3 has been associated with a myriad of clinical presentations, from PDNS to porcine respiratory disease complex (PRDC). This review paper summarizes the studies on PCV3 to date, with focus on diagnosis.
