Obstetric Outcomes in High-Order Repeat Caesarean Deliveries in Nigeria: A Single-Center Retrospective Study.

Objective: Our aim was to evaluate the trend of effect of prior caesarean delivery (CD) on obstetric outcomes; and to investigate the existence of a threshold for order of CD associated with geometrical increase in complications. Materials and methods: We performed a retrospective cohort study of 942 parturients who undergone CD between June 2012 and May 2015 in a teaching hospital in Nigeria. The participants were stratified by the order of caesarean deliveries. We used linear-to-linear association to assess presence of a trend between the order of CD and categorical variables while Jonckheere-Terpstra was used to investigate whether a trend exist between order of CD and continuous variables. We also used multivariate logistic regression to evaluate the relative risk ratio of the outcome variables for each order of CD. Results: Composite adverse maternal outcome depicted a significant increasing trend from 1st CD (5.2%) to the 5thCD (50%). The relative risk ratio for composite adverse maternal outcome increased arithmetically from 1st CD to 3rd CD: RRR2.21, 95%CI 1.2-3.98 for 2ndCD; RRR3.39, 95%CI 1.60-9.27 for 3rdCD; followed by a geometric increase between 3rdCD and 4thCD (RRR11.64, 95%CI 3.20-18.86). In contrast, composite adverse fetal outcome did not depict a significant trend. However, perinatal death increased significantly from primary CD (4.6%) to 5thCD (33.3%). Conclusion: Maternal and fetal complications of repeat CD increase with increasing order of CD; and this trend became astronomical after the third CD. Couples should be counselled that both maternal and fetal complications increase with each additional CD and advised strongly to forgo future pregnancies after the 3rd CD.

Eight-hour versus 24-h urethral catheter removal following elective caesarean section for reducing significant bacteriuria: A randomized controlled trial.

BACKGROUND: There is no consensus on the preferred time to remove urethral catheter post caesarean section. AIM: To compare rate of significant bacteriuria and urinary retention following 8-h (study) and 24-h urethral catheter removal (control) post elective caesarean section. METHODS: A randomized controlled trial of eligible participants that underwent elective caesarean section under spinal anaesthesia between March 2019 and November 2019 was conducted. Participants (150 in each arm) were randomly assigned (1:1 ratio) to either 8-h or 24-h group. Primary outcome measures included rates of significant bacteriuria 48-h post-operatively and acute urine retention 6-h post urethral catheter removal. Analysis was by Intention-to-treat. (www.pactr.org:PACTR202105874744483). RESULTS: There were 150 participants randomized into each arm and data collection was complete. Significant bacteriuria was less in 8-h group (3% versus 6.0%; risk ratio (RR): 0.85 CI: 0.60 to 5.66; p = 0.274), though not significant. Acute urinary retention requiring repeat catheterisation was significantly higher in 8-h group (11(7.3%) versus 0(0.0%); RR: 0.07; CI: 0.87 to 0.97; p = 0.001). Mean time until first voiding was slightly higher in 8-h group (211.4 ± 14.3 min versus 190.0 ± 18.3 min; mean difference (MD): 21.36; CI: -24.36 to 67.08; p = 0.203); but patient in this group had a lower mean time until ambulation (770.0 ± 26.1 min versus 809 ± 26.2 min; MD: -38.8; CI: -111.6 to 34.0; p = 0.300). The 8-h group were significantly more satisfied (82/150 (54.7%) versus 54/150 (36.0%); p = 0.001). CONCLUSIONS: An 8-h group was associated with significant clinical satisfaction and acute urine retention compared to 24-h removal. The timing of urethral catheter removal did not affect rate of significant bacteriuria and other outcomes.

The incidence of lower mid-trunk hyperpigmentation (linea nigra) is affected by sex hormone levels.

The incidence of linea nigra was studied in 1,550 Nigerians of both sexes and of different age groups and among pregnant women and men with benign and malignant prostatic diseases over a nine-month period. From the study, it would appear that linea nigra increases in incidence from the age group 0-15 years (31.4%) to the age group 16-30 years (47.3%) before starting to fall in clinically normal individuals >30 years to 19.2%. For age groups 0-5 years, 6-10 years and 16-30 years, females more often than males have a linea nigra. For age group 11-15, males are equally as likely as females to have a linea nigra. The results suggest that women over 30 are more likely to have a linea nigra than men, but there are too few patients to make a definite statement, given the number of statistical tests performed. Pregnant women far more often have a linea nigra than nonpregnant women of the same age. The findings suggest that the likelihood of having a linea nigra depends on the level of sex hormones. This means that changes in the levels of hormones, either due to disease or drugs, may be reflected in changes in the incidence of a linea nigra. If this finding is confirmed, the linea nigra may serve as a convenient, noninvasive, free marker of alterations in sex hormones.
