Histopathological Results and the Outcome of Women Who Underwent Postpartum Evacuation and Pelvic Ultrasound Scan.

Objectives: This study aimed to assess the proportion of women who underwent postpartum evacuation and were histopathologically confirmed to have retained products of conception (RPOC), compare the reliability of histopathology and ultrasound (US) in determining the presence of RPOC, and assess the maternal complications associated with postpartum evacuation. Methods: A retrospective cross-sectional study was conducted on all women who delivered and had postpartum evacuation at a tertiary teaching hospital in Oman over 11 years from May 2009 to May 2020. The participants were divided into two groups based on their histopathology results. McNemar test was used to compare the sonographic results with the histopathological findings. Results: A total of 151 women were included in this study. The diagnosis of RPOC was confirmed in histopathological reports of 64 (42.4%) women (group 1) but not in 87 (57.6%) women (group 2). There was no significant difference between the two groups in maternal characteristics. Parameters of clinical presentation including fever and abdominal pain were significantly different between the two groups (p =0.026 and p =0.028, respectively). Vaginal bleeding was not significantly different between the groups (p =0.255). Pelvic US detected RPOC in 135 (89.4%) women whereas the histopathology confirmed it in 64 (42.4%) women (p < 0.001). The sensitivity of US compared to histopathology in diagnosing RPOC was 98.4% (95% CI: 91.60-99.96) and the specificity was 17.2% (95% CI: 9.98-26.84). The overall diagnostic accuracy of US in detecting RPOC was 51.7%. Two (1.3%) women had hysterectomy as a result of the evacuation. Histopathology showed smooth muscle in 20 (13.2%) women. Significant bleeding during surgery occurred in 17 (11.3%) cases. Conclusions: Diagnosis of postpartum RPOC is challenging. Our results highlighted the complexity of diagnosing RPOC. Special training is needed for doctors to diagnose RPOC from transvaginal scans. A multicenter study in Oman with a larger sample size is recommended to confirm our findings.

Effects of maternal age, parity and pre-pregnancy body mass index on the glucose challenge test and gestational diabetes mellitus.

OBJECTIVES: To study the effects of age, parity and body mass index (BMI) on the incidence of a positive 50 g glucose challenge test (OGCT) and gestational diabetes mellitus (GDM) in healthy pregnant Omani women. METHODS: A 50 g OGCT was performed on 307 healthy pregnant Omani women at 24-28 weeks of gestation. When the venous plasma glucose concentration (VPG) reached >7.8 mmol/l after 1 h, the OGCT was considered to be positive. Women with positive OGCTs had a confirmatory diagnosis of GDM, which was established by performing a 2-h 75 g oral glucose tolerance test (OGTT). When either fasting or post-2-h 75 g OGTT values were >5.5 mmol/l or >8 mmol/l, respectively, women were considered diabetic. RESULTS: This study screened 307 women and identified 83 (27.03%) OGCT-positive and 23 (7.5%) GDM-positive cases. The incidences of a positive OGCT and GDM increased significantly with increasing maternal age from 20.0% to 2.2%, respectively, in women aged ≤25 years to 37.8% and 14.7%, respectively, in women aged >35 years (p = 0.02 and p = 0.009, respectively). The incidences of a positive OGCT and GDM increased markedly with increasing pre-pregnancy BMI, from 19.8% to 3.8%, respectively, in women with BMIs ≤25 kg/m2 to 37.8% and 9.9%, respectively, in women with BMIs >25 kg/m2 (p = 0.02 and p = 0.04, respectively). CONCLUSION: Maternal age and pre-pregnancy BMI have profound effects on the incidences of a positive OGCT and GDM.

50 Grams Oral Glucose Challenge Test: Is It an Effective Screening Test for Gestational Diabetes Mellitus?

AIM: To find out whether 50 g oral glucose challenge test (OGCT) is an effective screening test for all pregnant women between 24 and 28 weeks gestation. METHOD: A 50 g OGCT test was administered to 307 unselected women at 24-28 weeks of gestation. When venous plasma glucose (VPG) concentration after 1 h was >7.8 mmol/l, OGCT was positive. Women with a positive OGCT underwent 2 h 75 grams oral glucose tolerance test (OGTT) as a confirmatory diagnosis of GDM. When fasting and 2 h post 75 g OGTT values were >5.5 mmol/I and >8 mmol/l, respectively, women were considered diabetic. RESULTS: We screened 307 women for GDM by OGCT. Total number of women with positive OGCT was 83 (27.03 %). In the low-risk group, total number of women with GDM was 9/168 (5.35 %) while the total number of women with GDM in the high-risk group was 14/139 (10.07 %). There was no significant difference with respect to the total number of women with GDM in the groups. CONCLUSIONS: A 50 g OGCT seems to be an effective screening test for both groups. More cases of GDM can be discovered when universal rather than risk-related screening is applied.

Early Teenage Pregnancy: Is it Safe?

AIM: To compare obstetric and perinatal outcomes of early and late teenage pregnancies of Omani nulliparous women with singleton pregnancies cared for and delivered at a tertiary teaching hospital. METHOD: In this retrospective study, we reviewed obstetric and perinatal outcomes of early teenage pregnancies (14-16 years), (n = 20) delivered at Sultan Qaboos University Hospital, Muscat, Oman, between 1 July 2006 and 30 June 2013 and compared their outcomes with outcomes of late teenage pregnancies (17-19 years), (n = 287) delivered at the same hospital during same period. RESULTS: When compared with late teenage pregnant women, early teenagers were found to have no significant differences in prevalence of very preterm delivery <32 weeks (P = 0.62), preterm rupture of membranes (P = > 0.99), and anemia (P = 0.34). When compared to late teenagers, early teenagers had similar cesarean sections rates (P = >0.99), instrumental delivery rates (P = 0.56) and spontaneous vaginal delivery rates (P > 0.99). Both groups had similar birth weights (P = 0.87), low birth weights, (P = 0.55), and very low birth weights babies (P = 0.56 %). Perinatal mortality rate was similar in both groups. CONCLUSION: We may conclude that early teenage pregnant Omani women are not at increased risk of obstetric and perinatal complication compared to older teenagers.

Symptomatic Urinary Tract Infection in Diabetic Pregnant Women, Effect of the Type of Diabetes and Glycemic Control.

OBJECTIVES: To compare the prevalence of symptomatic urinary tract infection (S-UTI) in women with gestational diabetes mellitus (GDM), pregestational diabetes mellitus (PGDM), and the effect of glycemic control methods. MATERIALS AND METHODS: This is a retrospective review of women with GDM and PGDM, who had S-UTI treated at Sultan Qaboos University Hospital between January 1, 2009, and December 31, 2010. RESULTS: From a total of 639 women with diabetes mellitus (DM), 91% (n = 581) had GDM and 9% (n = 58) had PGDM. The prevalence of S-UTI was 6.7% (n = 43). The prevalence of S-UTI was 6.5% (n = 38) in women with GDM and 8.6% (n = 5) in women with PGDM. In women with GDM, S-UTI occurred in 4.6% (n = 5) of insulin users compared to 6.9% (n = 33) in noninsulin users. Differences were not statistically significant. CONCLUSION: The prevalence of S-UTI is similar in women with GDM and PGDM regardless of the method used for glycemic control.

Gestational and Pregestational Diabetes Mellitus in Omani Women: Comparison of obstetric and perinatal outcomes.

OBJECTIVES: The aim of this study was to assess the prevalence of gestational diabetes mellitus (GDM) and pregestational diabetes mellitus (PGDM) among pregnant women in Oman and compare their obstetric and perinatal outcomes. METHODS: This retrospective study assessed the obstetric and perinatal outcomes of pregnant Omani women with GDM or PGDM who delivered at the Sultan Qaboos University Hospital in Muscat, Oman, between January 2009 and December 2010. RESULTS: There were a total of 5,811 deliveries during the study period. Of the 5,811 women who gave birth, 639 women were found to have diabetes mellitus (11.0%). A total of 581 of the diabetic women had GDM (90.9%) and only 58 (9.1%) had PGDM. Women with PGDM had a significantly higher incidence of pre-eclampsia (P = 0.022), preterm deliveries (P <0.001) and Caesarean sections (P <0.001). Neonatal complications, such as respiratory distress syndrome (RDS), neonatal hypoglycaemia, neonatal jaundice and subsequent admission to a neonatal intensive care unit (NICU) were significantly higher for neonates born to mothers with PGDM compared to those born to mothers with GDM (P <0.001). The corrected perinatal mortality rates for women with PGDM and GDM were 34.5 and 13.7 per 1,000 live births, respectively. CONCLUSION: In this Omani cohort, women with PGDM were at higher risk of developing obstetric and perinatal complications such as pre-eclampsia, preterm delivery and Caesarean delivery compared to women with GDM. In addition, neonates who had mothers with PGDM had higher rates of RDS, neonatal hypoglycaemia, neonatal jaundice and admission to the NICU.

Obstetric and perinatal outcomes of teenage pregnant women attending a tertiary teaching hospital in oman.

OBJECTIVE: To study the obstetrical and perinatal outcomes of teenage Omani girls with singleton pregnancies at a tertiary teaching hospital. METHODS: This is a retrospective case control study. We reviewed obstetric and perinatal outcomes of teenage nulliparous pregnant Omani girls with singleton pregnancies aged 14 to 19 years, delivered at Sultan Qaboos University Hospital, between 1 July 2006 and 30 June 2013. We compared their outcomes with outcomes of pregnant nulliparous Omani women with singleton pregnancies aged 20 to 25 years old delivered at the same hospital during the same period. RESULTS: When compared with pregnant women (n=307), teenage pregnant girls (n=307) were found to have higher proportion of preterm delivery <32 weeks (7% vs. 3%, p=0.040), preterm pre-labor rupture of membranes (PPROM) (19% vs. 11%, p=0.005) and anemia (58% vs. 44%, p=0.005). Cesarean section rate was higher in women than teenager girls (20% vs. 10%, p=0.001). Teenager girls had lighter babies (mean weight ± standard deviation 2,750±690 vs. 2,890±480, p=0.020), incidence of very low birth weight babies (<1,500g) was higher in teenagers (3.9% vs. 0.3%, p=0.003), but perinatal mortality rate was similar in the two groups. CONCLUSION: Teenage pregnant Omani women are at increased risk of preterm delivery before 32 weeks gestation, PPROM, anemia, and delivering very low birth weight babies.
