Pentazocine with rectal diclofenac versus pentazocine alone for pain relief following caesarean delivery in Enugu, Nigeria: A randomized controlled trial.

OBJECTIVE: To measure postoperative pain relief following the use of rectal diclofenac combined with intramuscular pentazocine compared with intramuscular pentazocine alone in patients undergoing a caesarean delivery. METHODS: This single-blind randomized controlled trial enrolled pregnant women that had a caesarean section at the Enugu State University of Science and Technology Teaching Hospital, Enugu, Nigeria. Study participants were randomized to receive either 100 mg of rectal diclofenac given every 12 h plus 30 mg of intramuscular pentazocine given every 6 h (group A) or 60 mg of intramuscular pentazocine given every 6 h (group B). The primary outcome was the level of pain as measured using a visual analogue scale. The secondary outcomes were the level of satisfaction with pain relief and need for rescue analgesia. RESULTS: A total of 200 participants were randomized equally into the two groups. Participants in group A had significantly better pain control and satisfaction over the 48 h after surgery compared with group B. Significantly more of group B required rescue analgesia for breakthrough pain compared with group A. CONCLUSION: Rectal diclofenac combined with intramuscular pentazocine was significantly better at controlling pain compared with pentazocine alone in the first 48 h following caesarean section.Trial registration number: PACTR202107706925314 at www.pactr.org on 28 July 2021.

Effect of treatment with single total-dose intravenous iron versus daily oral iron(III)-hydroxide polymaltose on moderate puerperal iron-deficiency anemia.

BACKGROUND: Iron-deficiency anemia is the most common nutritional cause of anemia in pregnancy and is often responsible for puerperal anemia. Puerperal anemia can impair postpartum maternal and neonatal well-being. OBJECTIVE: To determine the effect of treatment of moderate puerperal iron-deficiency anemia using a single intravenous total-dose iron dextran versus daily single dose oral iron(III)-hydroxide polymaltose. METHODOLOGY: A randomized controlled study in which postpartum women with moderate iron-deficiency anemia were randomized into treatment with either a single total-dose intravenous iron dextran or with daily single doses of oral iron(III)-hydroxide polymaltose tablets for 6 weeks. Effects on hemoglobin concentration using either method were compared at 6 weeks postpartum. Analysis was per protocol using SPSS version 17 for windows. P-values ≤0.05 were considered significant. RESULTS: Two hundred eighty-four women were recruited for the study: 142 women received single total dose intravenous infusion of iron dextran while 142 received daily oral iron(III)-hydroxide polymaltose tablets. Approximately 84.0% (237/282) completed the study and were analyzed including 81% (115/142) of those randomized to injectable iron therapy compared to 85.9% (122/142) of those randomized to oral treatment. The proportions of women who had attained hemoglobin concentration of at least 10 g/dL by the 6 weeks postpartum visit did not differ significantly between cases and controls (95.7% vs 94.3%; P=0.73). Similarly, the mean increases in hemoglobin following either therapeutic route were comparable (1.03±0.56 g/dL for intravenous iron and 0.97±0.46 g/dL for the oral group; P=0.42). CONCLUSION: Single total-dose intravenous iron for treatment of puerperal iron-deficiency anemia was as effective as daily single doses of ferric iron tablets. For puerperal patients with iron-deficiency anemia in whom compliance with and tolerability of oral iron are not certain, a single total-dose intravenous iron can be safely offered.

Accuracy of a combined insulin-like growth factor-binding protein-1/interleukin-6 test (Premaquick) in predicting delivery in women with threatened preterm labor.

PURPOSE: To determine values of combinations of interleukin-6 (IL-6)/cervical native insulin-like growth factor-binding protein-1 (IGFBP-1)/total IGFBP-1 (Premaquick©) in predicting spontaneous deliveries and spontaneous exclusive preterm deliveries in women with threatened preterm labor. METHODS: Women with singleton pregnancies between gestation age (GA) of 24 weeks and 36 weeks and 6 days with preterm labor were recruited during a prospective multicenter study. Premaquick© was positive when at least two of three biomarkers were positive. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and accuracy were estimated for both prediction of spontaneous deliveries and spontaneous exclusive preterm deliveries. RESULTS: Ninety-seven (99.0%) out of 98 women enrolled were analyzed. Based on delivery status 7/14 days post-enrollment of general study population, Premaquick© had a sensitivity of 87.1/85.7%, a specificity of 92.4/96.8%, a PPV of 84.4/93.8% and a NPV of 93.9/92.3% for prediction of spontaneous delivery. Predictive accuracy of Premaquick© test in relation to days of enrollment were: 90.7% (≤7 days) and 92.8% (≤14 days). For women enrolled at GA <35 weeks, Premaquick© had a sensitivity of 100.0/87.5%, a specificity of 94.1/96.9%, a PPV of 70.5/87.5%, a NPV of 100.0/96.9% and an accuracy of 95.0/95.0% for prediction of preterm delivery within 7/14 days of enrollment, respectively. PPV was most significantly different in both groups when outcomes were compared between 2 days and 14 days post-enrollment (P<0.001). CONCLUSION: This novel triple biomarker model of native and total IGFBP-1 and IL-6 appears to be an accurate test in predicting spontaneous deliveries and spontaneous exclusive preterm deliveries in threatened preterm labor in singleton pregnancies.

Comparison of the duo of insulin-like growth factor binding protein-1/alpha fetoprotein (Amnioquick duo+®) and traditional clinical assessment for diagnosing premature rupture of fetal membranes.

PURPOSE: To determine the diagnostic accuracy of insulin-like growth factor binding protein-1/alpha fetoprotein (Amnioquick duo+®) compared with traditional clinical assessment (TCA) of nitrazine, ferning and pooling for the diagnosis of prelabor rupture of membranes (PROM). METHODS: A double-blinded, multicenter clinical study was conducted between February 2015 and August 2015 among pregnant women presenting with symptoms or features suggestive of PROM between 24 and 42 weeks gestation. Confirmation of PROM was done after delivery based on the presence of any two of these criteria: delivery within 48 h to 7 days, evidence of chorioamnionitis, membranes explicitly ruptured at delivery and adverse perinatal outcomes strongly correlated with prolonged PROM. Sensitivity, specificity and accuracy were outcome measures assessed. RESULTS: Two hundred and thirty-six women were recruited. Three women were excluded from the final analysis due to lack of follow-up data and failure to meet inclusion criteria. Two hundred and thirty-three women had complete data for analysis. The specificity and sensitivity values for TCA were 76.2% and 85.2%, which were lower than those of Amnioquick duo+, which were 97.6% and 97.9%, respectively. The accuracy of Amnioquick duo+ was statistically higher (97.9% vs. 83.7%; RR=1.17; 95%CI=1.10-1.24; P<0.001). In equivocal cases (pooling=negative), the accuracy of Amnioquick duo+ vs. TCA was 98.4% vs. 69.4% (RR=1.42; 95%CI=1.20-1.68; P<0.001) at ≥34 weeks gestation and 100.0% vs. 71.4% (RR=1.40; 95%CI=1.07-1.83; P=0.021) at <34 weeks gestation. CONCLUSION: The performance matrix of Amnioquick duo+® was superior to that of TCA for diagnosing PROM even in equivocal cases.

Rate and predictors of low serum ferritin levels among healthy parturient women in Enugu, Nigeria.

BACKGROUND: Low serum ferritin levels signify low iron stores and this could predispose to iron deficiency anemia. OBJECTIVE: To determine the rate and predictors of low serum ferritin levels during the puerperium in Enugu, Southeast Nigeria. STUDY DESIGN: A hospital-based prospective longitudinal study involving parturient women who delivered singleton fetuses at term. Venous blood samples were collected to determine the serum ferritin concentration at 48 hours and 6 weeks postpartum. Data analysis involved descriptive and inferential statistics at 95% confidence interval (CI) using Statistical Package for Social Sciences (SPSS) computer software version 20.0. RESULTS: Two-hundred and two women who carried singleton pregnancies to term were studied. The mean serum ferritin levels at 48 hours and 6 weeks were 27.82±18.41 µg/L and 36.12±21.53 µg/L, respectively. Forty-eight hours postdelivery, 29.2% had low ferritin levels and this decreased to 12.4% at 6 weeks postpartum. There was a significant positive correlation between the serum ferritin level at 48 hours postdelivery and the serum ferritin level at 6 weeks postpartum (r=0.89, P<0.001). Predictors of the low ferritin level at 6 weeks included age <20 years (odds ratio [OR] =0.70, 95% CI =0.53, 0.93), multiparity (OR =63.7, 95% CI =3.18, 127.5), anemia at 48 hours postpartum (OR =61.7, 95% CI =13.27, 116.6), a low ferritin level at 48 hours (OR =78.1, 95% CI =8.8, 108.3), and intake of antenatal hematinics for <3 months (OR =0.04, 95% CI =0.01, 0.20). CONCLUSION: There was a significant occurrence of low ferritin levels during the puerperium in the study centers, and this was associated mainly with pregnancy and delivery factors. Efforts to improve the iron stores in parturient women could benefit from early booking and compliance with antenatal hematinics and optimizing hemoglobin and iron levels before delivery.

Successful pregnancy following myomectomy for giant uterine fibroid in an infertile woman.

BACKGROUND: Giant uterine fibroid is a rare tumor of the uterus, usually symptomatic requiring surgical intervention. Uterine fibroid is generally common among black women. CASE PRESENTATION: In this study, a case of 31 year old nullipara was reported who presented to the Gynaecology unit of Enugu State University Teaching Hospital (ESUTH), Nigeria with a history of progressive abdominal swelling of 8 years duration, six years duration of infertility and weight loss and dyspnoea on exertion. Physical examination and transabdominal ultrasound revealed a huge abdominopelvic mass. She had myomectomy. She had a histologically confirmed giant uterine fibroid that weighed 16.8 kg. She subsequently achieved a live birth. CONCLUSION: Giant uterine fibroids are relatively rare. It poses great challenges in its management. The surgical option of management should consider the fertility preservation and aspiration of couples especially in developing countries.

Challenges associated with the management of gynecological cancers in a tertiary hospital in South East Nigeria.

BACKGROUND: There are reports of increasing incidence of gynecological cancers in developing countries and this trend increases the need for more attention to gynecological cancer care in these countries. OBJECTIVE: The purpose of this study was to describe the presentation and treatment of gynecological cancers and identify barriers to successful gynecological cancer treatment in a tertiary hospital in South East Nigeria. METHODS: This study was a retrospective longitudinal analysis of the presentation and treatment of histologically diagnosed primary gynecological cancers from 2000 to 2010. Analysis was by descriptive and inferential statistics at the 95% level of confidence using Statistical Package for the Social Sciences version 17 software. RESULTS: Records of 200 gynecological cancers managed during the study period were analyzed. Over 94% of cervical cancers presented in advanced stages of the disease and received palliative/symptomatic treatment. Only 1.9% of cervical cancer patients had radical surgical intervention, and postoperative mortality from these radical surgeries was 100%. Approximately 76% of patients with ovarian cancer had debulking surgery as the mainstay of treatment followed by adjuvant chemotherapy. Postoperative mortality from ovarian cancer surgery was 63%. Cutting edge cytotoxic drugs were not used as chemotherapy for ovarian and chorionic cancers. Compliance with chemotherapy was poor, with over 70% of ovarian cancer patients failing to complete the prescribed courses of chemotherapy. Most patients with endometrial and vulval cancers had only surgical treatment, as compliance with follow-up for adjuvant chemotherapy or radiotherapy was poor. Functional radiotherapy facilities were not available at the center during the study period, thereby necessitating external referrals to centers hundreds of kilometers away. CONCLUSION: Late presentation of cases, noncompliance with treatment regimens, lack of use of cutting edge cytotoxic drugs, the poor outcome of radical surgeries, and lack of a functional radiotherapy facility combined to create a very difficult gynecological cancer care environment at the study center.

Membrane stripping to prevent post-term pregnancy in Enugu, Nigeria: a randomized controlled trial.

OBJECTIVES: This study aimed at evaluating the effectiveness and safety of membrane stripping at 40-41 weeks of gestation as a means of preventing post-term pregnancy and the need for formal induction of labor in Enugu, Nigeria. METHODOLOGY: A randomized controlled trial of 134 post-date pregnant women at the University of Nigeria Teaching Hospital, Enugu, Nigeria, from February to November 2012. The intervention group received membrane stripping while the control group did not receive membrane stripping. RESULTS: The incidence of post-term pregnancy in the membrane stripping group was 16.1% (10/62) versus 39.3% (24/61) in the control group (RR 0.41; 95% CI 0.22-0.78; P = 0.004; NNT = 4). Membrane stripping reduced the duration of pregnancy by 3 days (P < 0.001). The procedure also significantly reduced the need for 'formal' labor induction [7/62 (11.3%) vs. 23/61 (37.7%); RR 0.30; 95 CI 0.14-0.65; P = 0.002]. However, maternal and neonatal complications were similar between the two groups. CONCLUSION: Membrane stripping reduces the incidence of post-term pregnancy and need for formal induction of labor in post-date pregnant women, without increased maternal or neonatal complications.
