A Prospective Study

<p><strong>Introduction:</strong> Most of miscarriage events occurred during the first trimester of pregnancy. Recent studies found the beneficial effects of maternal serum markers to predict pregnancy outcomes. However, study in Indonesian setting was still limited, especially in outpatient setting. The aim of this study was to evaluate serum progesterone and β-hCG measurement  as a beneficial predictor of miscarriage.</p><p><strong>Materials &amp; Methods:</strong> This was a prospective study recruiting outpatients pregnant women in Aceh who seek first medical attention for their pregnancy during January 2013 to January 2015. Serum progesterone and β-hCG level were measured beside routine obstetric procedure. The discrimination attained between miscarriage and non-miscarriage groups of pregnant women at the end of first trimester was evaluated using logistic regression and receiver operating curve analysis.</p><p><strong>Results: </strong>Among 70 pregnant recruited in this study, nineteen of them (27.1%) experienced miscarriage. Serum progesterone level of women in miscarriage group was lower than non-miscarriage group (17.85 (IQR 13.26-21.15) ng/dl vs 33.67 (IQR 21.83-44.14), p&lt;0.001). Serum β-hCG level was also lower in miscarriage group (10 681 (IQR 5 787.5-26 577.5) mIU/ml vs 48 109 (IQR 17 137-93 915) mIU/ml, p=0.001). Single progesterone measurement gave a good predictor ability for miscarriage with 82.2% accuracy, 86.3% sensitivity and 73.7% specificity if 19.5 ng/dl was used as a cut-off point.</p><strong>Conclusion: </strong>Maternal serum progesterone level could be a good predictor for miscarriage during the first trimester of pregnancy. Single β-hCG serum in combination with progesterone serum measurement only had little added value for predicting miscarriage.

Detection Rates

The potential efficacy of screening for trisomy 21 in the first trimester, using maternal serum markers α fetoprotein, free β human chorionic gonadotropin, unconjugated oestriol and pregnancy associated plasma protein A, was studied in an unselected population of women between the seventh and fourteenth week of gestation. Using a combination of α fetoprotein and free β human chorionic gonadotropin, 53% of affected pregnancies could be identified at a false positive rate of 5%. Unconjugated oestriol and pregnancy associated plasma protein A levels were lower in cases of trisomy 21, but their inclusion with other markers did not significantly improve detection rate. Monitoring the same pregnancies also in the second trimester showed that screening in the first trimester identified the same cases as in the second. We conclude that first trimester screening using free β human chorionic gonadotropin and α fetoprotein, is a viable possibility and will lead to detection rates in excess of 50%. Prospective studies are needed to confirm these observations.

A Prospective Study

Background: Ectopic pregnancy is one in which the fertilized ovum is implanted and develops outside the endometrial cavity. It is an important cause of maternal morbidity and mortality in first trimester. The present study was conducted to study the risk factors, clinical presentation and management of ectopic pregnancy in RIMS, Ranchi, Jharkhand, India.Methods: This was a prospective study conducted in the department of obstetrics and gynaecology, RIMS, Ranchi, Jharkhand during May 2017 to September 2018. A total of 90 cases were included in the study.Results: 80% of the patients presented with amenorrhoea, 98% had abdominal pain and 69% had vaginal bleeding. Ultrasonography revealed hemoperitoneum in about 93% patients. 16 (18%) patients had history of infertility whereas 10 patients (11%) had taken treatment of infertility.6 (7%) patients had history of STD or PID.14 (16%) had undergone bilateral tubectomy.2 (2%) had history of IUCD insertion and 12 (13%) patients had undergone previously lscs. 54 patients (60%) had undergone D and C and 6 patients (7%) had a previous history of ectopic pregnancy. 68 (76%) underwent only salpingectomy.12 (13%) had salpingo-oophorectomy and 10 (11%) had salpingectomy with contralateral tubectomy.Conclusions:Diagnosis of ectopic pregnancy requires clinical suspicion and supportive investigations like UPT, ultrasonography, β HCG and laparoscopy. It is an important cause of admission to RIMS as maternal near miss cases.Background: Ectopic pregnancy is one in which the fertilized ovum is implanted and develops outside the endometrial cavity.
