    The aim of the present study was to analyze the immunolocalization of insulin-like growth factor (IGF)-1 and IGF-2 and their receptors in the oviduct and uterus of control and diabetic mice. Sexually mature female ICR mice aged 6-8 weeks were rendered diabetic by streptozotocin (200 mg/kg, administered intraperitoneally). Oviductal and uterine tissues were obtained from the superovulated control and diabetic mice at 48, 72 and 96 h post-human chorionic gonadotropin (hCG) treatment. Localization of IGF-1, IGF-2, IGF-1R and IGF-2R was determined by immunohistochemistry and a semi-quantitative scoring of immunolabelling was performed using a standardized 5-point system. The immunohistochemical scorings for both IGF-1 and IGF-1R were significantly decreased in the oviducts of diabetic mice at 96 h post-hCG treatment. The scores for IGF-2 were significantly increased in the oviducts of diabetic mice at 48 and 72 h post-hCG treatment, and for IGF-2R at 72 h post-hCG treatment. However, there was no significant difference in the scores of IGFs and their receptors in the uterus of control and diabetic mice. In conclusion, the oviductal immunolabelling for IGFs and their receptors was significantly altered by maternal diabetes, which may be of importance in the pathogenesis of preimplantation diabetic embryopathy.

    Of 36 cases of choriocarcinoma treated at the University Hospital Kuala Lumpur during 1980-84 inclusive, 6 patients were found to have cerebral metastases. Intrathecal methotrexate and combination chemotherapy were started in all cases, with monitoring of tumor growth by serial beta-HCG assays and CT scanning of brain and lung. Chemotherapy was reduced because of severe toxicity in 2 patients, one of whom received radiotherapy to the brain. Four patients (66%) have now been in remission for 2.5-6 years. Two did not respond to therapy and died. The factors involved in therapy and response are discussed.

    INTRODUCTION: Testicular cancer mainly affects young men worldwide. There is lack of published data on patients with this malignant condition from the Southeast Asian region. The aim of this study was therefore to determine the clinicopathologic features of testicular cancer patients treated in a Southeast Asian university hospital and their overall survival rate.

    MATERIALS AND METHODS: This was a retrospective study of testicular cancer patients treated between January 2001 and February 2011. Their epidemiological data, clinical presentation, pathologic diagnosis, stage of disease and treatment were gathered and the overall survival rate of this cohort was analyzed.

    RESULTS: Thirty-one patients were included in this study. The majority of them were of Malay ethnicity. The average age at presentation was 33.7 years. The commonest testicular cancer was non-seminomatous germ cell tumour, followed by seminoma, lymphoma and rhabdomyosarcoma. More than half of all testicular germ cell tumour (GCT) patients had some form of metastasis at diagnosis. All the patients were treated with radical orchidectomy. Adjuvant chemotherapy was given to those with metastatic disease. Four seminoma patients received radiotherapy to the para-aortic lymph nodes. The 5-year survival rate for all testicular cancers in this cohort was 83.9%. The survival rate was 88.9% in 5 years when GCT were analyzed separately.

    CONCLUSION: GCT affects patients in their third and fourth decades of life while lymphoma patients are generally older. Most of the patients treated for GCT are of Malay ethnicity. The majority have late presentation for treatment. The survival rate of GCT patients treated here is comparable to other published series in other parts of the world.

    A 25-year-old gravida 2 para 1 with 12-week amenorrhoea presented a second time for recurrent vomiting in pregnancy. She was diagnosed to have a missed miscarriage following absent fetal heart seen in an early scan. She opted for conservative management. However, on the third presentation, her vomiting continued. Repeated transvaginal ultrasound scan showed a fetus with a crown rump length of 19 mm, which is equivalent to 8 weeks and 4 days, with absence of fetal heart pulsation. Thyroid function tests and β human chorionic gonadotropin were then requested. Results showed that the patient's serum β human chorionic gonadotropin level was markedly raised to 147,000. A molar pregnancy was suspected. Her thyroid function tests came back normal. Suction curettage was performed and histopathology confirmed a partial molar pregnancy. On follow-up, the β human chorionic gonadotropin level was normal by 7 weeks after the curettage.

    Rationally designed biosensing system supports multiplex analyses is warranted for medical diagnosis to determine the level of analyte interaction. The chemically functionalized novel multi-electrode polysilicon nanogap (PSNG) lab-on-chip is designed in this study, facilitates multiplex analyses for a single analyte. On the fabricated 69nm PSNG, biocompatibility and structural characteristics were verified for the efficient binding of Human Chorionic Gonadotropin (hCG). With the assistance of microfluidics, hCG sample was delivered via single-injection to 3-Aminopropyl(triethoxy)silane (APTES) and Glycidoxypropyl(trimethoxy)silane (GPMS) modified PSNG electrodes and the transduced signal was used to investigate the dielectric mechanisms for multiplex analyses. The results from amperometric response and impedance measurement delivered the scale of interaction between anti-hCG antibody and hCG that exhibited 6.5 times higher sensitivity for the chemical linker, APTES than GPMS. Under optimized experimental conditions, APTES and GPMS modified immunosensor has a limit of detection as 0.56mIU/ml and 2.93mIU/ml (at S/N=3), with dissociation constants (Kd) of 5.65±2.5mIU/ml and 7.28±2.6mIU/ml, respectively. These results suggest that multiplex analysis of single target could enhance the accuracy of detection and reliable for real-time comparative analyses. The designed PSNG is simple, feasible, requires low sample consumption and could be applied for any given multiplex analyses.

    We assessed the analytical performance of the Abbott IMxTM immunoassay analyser for total beta human chorionic gonadotropin (Beta hCG), follicle-stimulating hormone (FSH) and luteinising hormone (LH). The within-run CVs for various analyte concentrations were 2% to 6% while those for between-run imprecision in routine assay ranged from 4% to 10%. IMxTM values correlated well with radioimmunoassay for beta hCG, and immunoradiometric assay for FSH and LH; the correlation coefficients (r) were 0.97, 0.99 and 0.98 for total beta hCG, FSH and LH respectively. The average sensitivities were approximately 3.1, 0.2 and 0.5 iu/l for beta hCG, FSH and LH, respectively. Sample carry-over was not detected and there was negligible cross-reaction between LH and beta hCG in the respective assays. The automatic sample dilution protocol for beta hCG was superior to the manual procedure. The IMxTM is easy to operate and is able to process 24 samples in 40-45 minutes.

    Serum human chorionic gonadotropin (hCG) and estradiol levels are higher in women with hyperemesis gravidarum (HG) than in unaffected pregnant controls. We postulated that higher levels of these hormones may be associated with clinically more severe HG. The aim of this study was to evaluate the effect of maternal hCG and estradiol levels on the severity of HG.

    Intramyometrial ectopic pregnancy (IMEP) is a rare form of ectopic pregnancy. It is defined as a conceptus implanted within the myometrium and is completely surrounded by myometrium with clear separation from both the uterine cavity and tubes. IMEP possesses not only diagnostic but also therapeutic challenge. The majority of reported cases were managed by hysterectomy. Early management of unruptured IMEP using methotrexate may help to preserve fertility. We, for the first time, report a case of ruptured IMEP managed successfully using suction and curettage followed by Bakri balloon tamponade and avoiding hysterectomy. Post-procedure, the patient received two doses of intramuscular methotrexate 50 mg/m2 due to plateauing serial beta human chorionic gonadotropin (β-hCG) levels and subsequently achieved undetectable level 10 weeks post-methotrexate. She also had complete resolution of the ectopic intramyometrial mass.

    The microheterogeneity property of hCG with regards to its sialic acid contents resulted in variable mobility of the glycoprotein in SDS-PAGE. The intact hCG molecule is composed of two dissimilar subunits, namely alpha- and beta-subunits. The identification of hCG bands in SDS-PAGE was accomplished by the immunoblotting experiment, whereby the antibody directed toward the specific region of beta-subunit of hCG was used. The data shows that the different mobility of intact hCG was attributed to the different degree of desialylation of the glycoprotein. Nevertheless, unlike the intact hCG, the mobility of its beta-subunit was not affected by its variety sialic acid content. This characteristic of beta-hCG is beneficial when semi-quantification of total hCG is required. Quantification of hCG using the HPLC-reversed phase C18 analytical column is not possible as the glycoprotein was eluted in multiple fractions at different retention times. The identification of denatured hCG (HPLC eluted fractions) was carried out by immunoblotting experiment whilst immunoassay technique failed to detect its presence in any fraction.

    OBJECTIVE: hCG is commonly used as an ovulation trigger in IVF. Its usage is associated with OHSS. GnRH agonist is an alternative to hCG and is associated with reduced incidence of OHSS. This study compared the cycle outcomes of GnRH agonists with hCG as an ovulation trigger in IVF cycles.

    METHODS: The medical notes of 209 IVF cycles receiving GnRH agonist and hCG as ovulation trigger over 18 months were reviewed in this retrospective study. The number and quality of mature oocytes, the number and quality of embryos, pregnancy rates, and outcomes were compared using Independent T-test or One-way ANOVA for normal distribution. The Mann-Whitney test or Kruskal-Wallis test was used for not normally distributed. p<0.05 was considered statistically significant.

    RESULTS: The cycle outcomes of 107 GnRH agonist-trigger and 102 hCG-trigger were compared. The MII oocytes retrieved and 2PN count was significantly higher in the GnRH agonist trigger group (p<0.001). Clinical pregnancy rate and ongoing pregnancy were higher in the GnRH agonist trigger group but were not statistically significant. The GnRH agonist trigger group was associated with low OHSS than the hCG trigger group (n=2(1.9%) and n=12(11.8%) respectively, p=0.004).

    CONCLUSION: GnRH agonist trigger is an option as a final maturation trigger in high-responder women undergoing IVF or ICSI cycles.

    Heterotopic interstitial pregnancy in natural conception is very rare. Definitive diagnosis is
    made by systematic pelvic ultrasound. Simultaneous viable conception observed in both intraand extra-uterine is pathognomonic of heterotopic interstitial pregnancy. We report a 34-yearold woman primigravida at 10 weeks’ amenorrhoea who underwent evacuation of retained
    product of conception for missed miscarriage. Intraoperatively, minimal product of conception
    was retrieved. Bedside pelvic ultrasound showed cystic mass at right superolateral part of
    uterine fundus suspicious of interstitial pregnancy. Cornual resection was performed via
    laparotomy. Histopathological examination showed presence of product of conception and
    interstitial pregnancy. Serum β-human chorionic gonadotropin dropped from 10,027 IU/l on day
    one post-ERPC to 210 IU/l at day three post-cornual resection. This case report highlighted
    the challenge in diagnosing heterotopic interstitial pregnancy conceived naturally. Timely
    diagnosis may avert dire consequences of massive haemorrhage from ruptured uterine cornua

    Ectopic pregnancy in the interstitial part of the fallopian tube (cornual pregnancy) is a rare condition but can be fatal. Traditionally, the treatment had been cornual resection or hysterectomy. More conservative approaches had been advocated recently. There is no consensus on the dose or number of methotrexate injections that should be used in the treatment of interstitial pregnancies. Single dose intramuscular methotrexate is one of the treatment options. However, the failure rate is higher if the serum beta-hCG (beta-human chorionic gonadotrophin) level is more than 5000 IU/L. We report a case of cornual ectopic pregnancy with high initial serum beta-hCG level being successfully treated with multiple doses of systemic methotrexate. MRI was used to assess clinical resolution of cornual ectopic pregnancy.

    A confirmatory and quantitative HPLC-tandem mass spectrometry (MS-MS) method for human chorionic gonadotropin hormone (hCG) at concentrations as low as 5 IU/l following immunoaffinity extraction of the glycoprotein from urine was developed. The extraction method involved retention of urinary hCG in the immunoaffinity column via specific antigen-antibody interaction. A variety of eluents were then used to quantitatively elute hCG from the immunoaffinity column. Qualitative and quantitative analysis of hCG were undertaken using MS-MS by identifying the amino acid sequence of the marker peptide betaT5 obtained from hCG by tryptic digestion and the peak areas of three product ions b(6)(+), b(9)(+) and y(11)(+), respectively.

    OBJECTIVES: Level of βhCG and the presence of any uterine mass of hydatidiform mole need a careful review or monitoring in order to prevent metastasis, provide an early treatment and avoid unnecessary chemotherapy.

    CASE PRESENTATION: A 36-year old fifth gravida patient who had a missed abortion was diagnosed as having a molar pregnancy with beta human chorionic gonadotrophin (βhCG) level of 509,921 IU/L. Her lung field was clear and she underwent suction and curettage (S & C) procedure. However, after six weeks, AA presented to the emergency department with a massive bleeding, although her βhCG level had decreased to 65,770 IU/L. A trans-abdominal ultrasound indicated the presence of an intra-uterine mass (3.0 × 4.4 cm). Nevertheless, her βhCG continued to show a declining trend (8,426 IU/L). AA was advised to undergo a chemotherapy but she refused, citing preference for alternative medicine like herbs instead. She opted for an "at own risk" (AOR) discharge with scheduled follow up. Subsequently, her condition improved with her βhCG showing a downward trend. Surprisingly, at six months post S & C, her βhCG ameliorated to 0 IU/L with no mass detected by ultrasound.

    CONCLUSIONS: Brucea javanica fruits, Pereskia bleo and Annona muricata leaves can potentially be useful alternatives to chemotherapy and need further studies.

    45,X/46,XY mosaicism is a rare disorder with a wide heterogeneity in its manifestations. An 18-year-old girl was referred to the endocrine clinic for investigation of her primary amenorrhea. Clinical examination was unremarkable. Hormonal profile was consistent with primary ovarian insufficiency and human chorionic gonadotropin (hCG) stimulation did not show evidence of active testicular tissue. Karyotyping studies by G-banding revealed a 45,X/46,XY karyotype. She was diagnosed with mosaic Turner syndrome with Y chromosomal material and investigation was performed to identify the presence of male gonads due to the risk of gonadal malignancy. Magnetic resonance imaging (MRI) of the pelvis did not show evidence of gonads. Laparoscopic exploration was proposed but the patient and parents refused opting for conservative management. This case highlights the challenges in the management of this rare condition.

    Case of co-existence of twin pregnancy of complete hydatidiform molar with viable intrauterine pregnancy is extremely rare with low incidence of 1 case for 20,000 – 100,000. It is associated with high risk of spontaneous abortion, preterm delivery, intrauterine death, bleeding, pre-eclampsia, and persistence trophoblastic disease (PTD). It may associate with biochemical derangement that may induce symptomatic manifestation to the mother. There are few cases reported in Asia population with significant clinical dilemma and management to the maternal and foetus. Here, we report a case of a young woman with previous bad obstetric history who presented with antepartum per-vaginal bleeding and was noted to have a twin pregnancy with complete hydatidiform molar and viable foetus. It was complicated with markedly elevated human chorionic gonadotropin (hCG) and hyperthyroidism. Postpartumly, her hCG level was persistently high and her condition progressed into gestational trophoblastic neoplasm.

    Objectives: Estradiol (E2) plays an important role in the pathophysiology of ovarian hyperstimulation syndrome (OHSS). This study aimed to evaluate the effect of fenugreek seed aqueous (FSA) extract on serum E2 levels in a rat model of OHSS.

    Methods: A total of 34 female Sprague Dawley rats, aged 18 days old, weighing 40 to 45 g, were randomly divided into negative control, positive control, and treatment groups. A daily dose of 1500 mg/kg per body weight of FSA extract was administrated orally to rats in the treatment group for 13 days. On day eight of the study, OHSS was induced in both positive control and treated groups by subcutaneous injection of pregnant mare's serum gonadotropin 50 IU for four consecutive days, followed by human chorionic gonadotropin 25 IU on the fifth day. The effect of FSA extract was evaluated by measuring the concentration of serum E2 using the enzyme-linked immunosorbent assay.

    Results: FSA extract reduced serum E2 level significantly in the treated OHSS model (p-value < 0.050) compared to the positive control group.

    Conclusions: The finding has important implications on the development of female infertility adjuvant drugs for safe assisted reproduction technology cycles in terms of OHSS prevention.

    Examination of routinely stained haematoxylin and eosin sections may sometimes prove inadequate in differentiating partial hydatidiform moles (PHM) from complete hydatidiform moles (CHM). While cytogenetic analysis can aid in the distinction, such facilities are not always available. The possibility of using immunohistochemistry to aid in the differentiation was studied. Twenty-five histologically proven CHM and 11 PHM were studied for their patterns of expression of human chorionic gonadotrophin (hCG), human placental lactogen (hPL) and placental alkaline phosphatase (PIAP). All CHM stained diffusely with hCG and focally with both hPL and PIAP irrespective of gestational age. Of PHM, 63.6% were diffusely positive for hCG, 27.3% for hPL and 54.5% for PIAP; the rest were focally positive. The hCG pattern changed from diffuse to focal with increasing gestational age of PHM, while those of hPL and PIAP became increasingly diffuse with gestational age. While these protein expressions may be applied in differentiating late PHM from CHM, it is not useful in first trimester cases. The most helpful application is that focal expression of hCG and diffuse expressions of hPL and PIAP is not seen in CHM, thereby excluding such a diagnosis. PHM, in contrast, can show either diffuse or focal expression of all 3 antigens.
