RESUMO
BACKGROUND: Speculum lubrication may help to reduce the pain experienced during Pap-smear collection and hence increase uptake of cervical cancer screening and repeat testing, but there are fears of its interference with cytological results. AIM: To determine and compare the adequacy of cervical cytology smears and the mean pain scores of women undergoing cervical cancer screening with or without speculum lubrication. METHODS: This was a randomised controlled study of 132 women having cervical cancer screening at a tertiary hospital in Nigeria. Sixty-six participants were randomly assigned to the 'Gel' and 'No Gel' groups, respectively. Pap smears were collected from each participant with a lubricated speculum ('Gel group') or a non-lubricated speculum ('No Gel group'). The primary outcome measures were the proportion of women with unsatisfactory cervical cytology smears and the mean numeric rating scale pain scores, while the secondary outcome measures were the proportion of women who were willing to come for repeat testing and the cytological diagnosis of Pap-smear results. RESULTS: The baseline socio-demographic variables were similar in both groups. There was no significant difference in the proportion of unsatisfactory cervical smear results between the two groups (13.6% vs. 21.2%, p = 0.359). However, the mean pain scores were significantly lower in the gel group than in the no gel group (45.04 vs. 87.96; p<0.001). An equal proportion of the participants in each group (90.9% vs. 90.9%; p > 0.999) were willing to come for repeat cervical smears in the future. CONCLUSION: Speculum lubrication did not affect the adequacy of cervical smears but significantly reduced the pain experienced during pap smear collection. Also, it did not significantly affect the willingness to come for repeat cervical smears in the future. TRIAL REGISTRATION: The trial was registered with the Pan-African Clinical Trial Registry with a unique identification and registration number: PACTR2020077533364675.

Background: Uterine cavity pathology may affect the endometrium or myometrium, resulting in distortion of the uterine cavity, and is responsible for 2%-5% of infertility. The methods for its assessment usually involve imaging modalities like pelvic ultrasonography, often transvaginal-(TVS), and hysterosalpingography-(HSG), with hysteroscopy-(HSC) as the gold standard. However, HSC is not readily available in resource-poor-settings. Purpose: To determine and compare the diagnostic accuracy of TVS and HSG in detecting uterine cavity pathology using HSC as a gold standard. Materials and Methods: A cross-sectional analytical study of consenting infertile women for evaluation of the uterine cavity using transvaginal-ultrasonography, hysterosalpingogram, and hysteroscopy. The primary-outcome-measures were the sensitivity, specificity, and accuracy of TVS and HSG in detecting uterine cavity abnormalities using HSG as the gold standard. Results: Eighty-eight participants were analysed for this study. The lesions confirmed on HSC were intrauterine-adhesions (43.1%), endometrial polyps (14.8%), submucous fibroids (18.2%), intrauterine-septum (13.6%), and cavity distortion (14.8%). The overall sensitivity with TVS was 57.7%, with a specificity of 97.6%, a positive-predictive-value (PPV) of 88.2%, and a negative-predictive-value (NPV) of 88.2%, giving a percentage-accuracy of 88.2%. In comparison, HSG had a sensitivity of 72.1%, a specificity of 99.4%, a PPV of 97.4%, and an NPV of 92.0%, giving an overall accuracy of 92.9%. The detection rates of TVS and HSG in this category were: fibroids (97.7% vs 89.8%; p = .0004) and adhesions (73.9% vs 87.5%; p = .0002), respectively. Conclusion: HSG appears to be the superior modality for detection of obliterative uterine cavity pathologies, while TVS is better suited for myometrium and endometrial lesions.
RESUMO
Objectives: To compare Premaquick biomarkers (combined insulin-like growth-factor binding protein 1 and interleukin-6) and cervical length measurement via transvaginal ultrasound for pre-induction cervical evaluation at term among pregnant women. Methods: A randomized clinical trial of consenting pregnant women at the Nnamdi Azikiwe University Teaching Hospital, Nnewi, Nigeria. The women were randomized equally into Premaquick group (n = 36) and transvaginal ultrasound group (n = 36). The cervix was adjudged 'ripe' if the Premaquick test was positive or if the trans-vaginal measured cervical length was less than 28 mm. The primary outcome measures were the proportions of women who needed prostaglandin analogue for cervical ripening and the proportion that achieved vaginal delivery after induction of labour. The trial was registered in Pan African clinical trial registry (PACTR) registry with approval number PACTR202001579275333. Results: The baseline characteristics were similar between the two groups (p > 0.05). There was no statistically significant difference between the two groups in terms of proportion of women that required prostaglandins for pre-induction cervical ripening (41.7 versus 47.2%, p = 0.427), vaginal delivery (77.8 versus 80.6%, p = 0.783), mean induction to delivery interval (22.9 ± 2.81 h versus 24.04 ± 3.20 h, p = 0.211), caesarean delivery (22.2 versus 19.4%, p = 0.783), proportion of neonate with birth asphyxia (8.30 versus 8.30%, p = 1.00) and proportion of neonate admitted into special care baby unit (16.7 versus 13.9%, p = 0.872). Subgroup analysis of participants with 'ripe' cervix at initial pre-induction assessment showed that the mean induction to active phase of labour interval and mean induction to delivery interval were significantly shorter in Premaquick than transvaginal ultrasound group. Conclusion: Pre-induction cervical assessment at term with either Premaquick biomarkers or transvaginal ultrasound for cervical length is effective, objective and safe with similar and comparable outcome. However, when compared with women with positive transvaginal ultrasound at initial assessment, women with positive Premaquick test at initial assessment showed a significantly shorter duration of onset of active phase of labour and delivery of baby following induction of labour.
RESUMO
Objective: The aim of this study was to determine the pattern and outcomes of higher-order multiple pregnancies in a tertiary hospital in Nigeria. Methods: This is a retrospective review of all cases of higher-order multiple pregnancies that were managed between 1 January 2012 and 31 December 2016 in Alex Ekwueme Federal University Teaching Hospital Abakaliki, Nigeria. Data obtained were represented with frequency tables, percentages, bar charts, and odds ratio. Results: There were 22 higher-order multiple pregnancies over the study period and 12,002 deliveries, giving a higher-order multiple prevalence rate of 0.2%. Five of the mothers (four triplets and one quadruplet) had in vitro fertilization (0.4 per 1000 deliveries), while other mothers conceived naturally. Many of the women (12, 54.6%) were in the 30-34 years age group, and more than half (16, 72.7%) were multiparas. More than half of the neonates were delivered preterm (13, 59.1%). Being booked is associated with better neonatal outcomes although not significant (odds ratio = 3.06. 95% confidence interval: 0.55-16.83, p = 0.197). Anemia was common in the antepartum and postpartum periods. Half of the women (11, 50%) were delivered by elective cesarean section and 7 (31.8%) by emergency cesarean section (C/S), while 4 (18.2%) had a spontaneous vaginal delivery. The neonates had a mean birth weight of 2.14 ± 0.35 kg. Overall, 61 neonates (91.0%) were born alive and 6 (9.0%) suffered perinatal deaths, giving a perinatal mortality rate of 89.8 neonates per 1000 live births. Conclusion: Our study shows that higher-order multiple pregnancies are high-risk pregnancies that are associated with fetal and maternal complications. Anemia is the commonest complication seen in our study. The majority had preterm delivery. Proper antenatal care and close feto-maternal monitoring are important in reducing adverse outcomes associated with these pregnancies.
