Pelvic exenteration for recurrent or persistent gynecologic malignancies: Clinical and histopathologic factors predicting recurrence and survival in a modern cohort.

OBJECTIVES: To explore pre-operative factors and their impact on overall survival (OS) in a modern cohort of patients who underwent pelvic exenteration (PE) for gynecologic malignancies. METHODS: A retrospective review was performed for all patients who underwent a PE from 1/1/2010 through 12/31/2018 at our institution. Inclusion criteria were exenteration due to recurrent or progressive carcinoma of the uterus, cervix, vagina or vulva, with histologically confirmed complete surgical resection of the malignancy. Exclusion criteria included PE for palliation of symptoms without recurrence, and for ovarian or rare histologic malignancies. Univariable and multivariable analysis were performed to identify factors predicting prolonged survival. RESULTS: Overall, 71 patients met the inclusion criteria. Median age at time of exenteration was 62 years (range, 28-86 years). Vulvar cancer was the most common primary diagnosis (32%); 30% had cervical cancer; 23%, uterine cancer; 15%, vaginal cancer. Median OS was 55.1 months (95% confidence interval (CI): 36-not estimable) with a median follow-up time of 40.8 months (95% CI: 1-116.1). On univariable analysis, age > 62 years (hazard ratio (HR) 2.71, 95% CI 1.27-5.79), American Society of Anesthesia (ASA) 3-4 (HR: 3.41 (95% CI 1.03-11.29), and vulvar cancer (HR 4.19 (95% CI 1.17-14.96) predicted worse OS. Tumor size and prior progression-free interval (PFI) did not meet statistical significance in OS analyses. On multivariable analysis, there were no significant factors associated with worse OS. CONCLUSIONS: PE performed with curative intent may be considered a treatment option in well-counseled, carefully selected patients, irrespective of tumor size and PFI before exenteration.

Urinary incontinence: prevalence, pattern, and opportunistic screening in Ile-Ife, Nigeria.

INTRODUCTION AND HYPOTHESIS: Urinary incontinence is a source of health-related poor quality of life. It is, however, rarely disclosed, except when specifically enquired about by the healthcare provider. This study determined the prevalence of urinary incontinence and opportunistic screening for it in women attending a general outpatient clinic. METHODS: A total of 1,250 consenting women attending a general outpatient clinic in Ile-Ife, a semi-urban town in Southwest Nigeria, were recruited into this cross-sectional study. Confidential post-consultation interviews were performed in each patient to determine whether they had been asked about urinary incontinence and whether they felt that they ought to have been asked. The Questionnaire for Urinary Incontinence Diagnosis (QUID) was administered to determine the prevalence and pattern of urinary incontinence. Results were expressed as proportions and compared using the Chi-squared test. RESULTS: The subjects' ages ranged from 20 to 100 years (mean = 46.8 ± 17.7 years). Sixty-five women had urinary incontinence (prevalence = 5.2 %). QUID classified 30 (2.4 %), 23 (1.8 %), and 12 (1.0 %) of them as having urge, stress, and mixed incontinence respectively. None of them self-reported incontinence to their physicians. Only 9 incontinent (13.8 %) and 44 continent women (3.7 %) had opportunistic screening (p < 0.001). Fifty of the incontinent women (76.9 %) felt that their physician ought to have asked them about it. Forty-eight of them (73.8 %) did not consider incontinence a sufficient reason for presentation in hospital, but the majority (90.7 %) desired treatment. CONCLUSION: Urinary incontinence was occasionally present, but usually undisclosed by women attending the general outpatient clinic, unless when specifically asked by their physicians. Opportunistic screening is therefore recommended in this setting.

Adjunctive rectal misoprostol versus oxytocin infusion for prevention of postpartum hemorrhage in women at risk: a randomized controlled trial.

AIM: The aim of this study was to evaluate the efficacy of adjunctive rectal misoprostol compared to oxytocin infusion in the prevention of primary postpartum hemorrhage after routine active management of the third stage of labor in women with identifiable risk factors for uterine atony. MATERIAL AND METHODS: A double-blind randomized controlled trial was carried out at Obafemi Awolowo University Teaching Hospitals Complex, Ile-Ife, Nigeria. A total of 264 parturients with known risk factors for postpartum hemorrhage were randomized to receive either rectal misoprostol (600 µg; n = 132) or oxytocin infusion (20 IU in 500 mL; n = 132) after routine active management of the third stage of labor. Intrapartum blood loss was measured using a combination of the BRASSS-V calibrated drapes and differential pad weighing. Hematocrit was measured intrapartum and 24 h postpartum. RESULTS: There was no significant difference (P = 0.07) in the mean intrapartum blood loss between the misoprostol (387.28 ± 203.09 mL) and oxytocin (386.73 ± 298.51 mL) groups. There was also no difference in the requirement for additional intervention for uterine atony (P = 0.74). Postpartum hematocrit drop and blood transfusion were, however, significantly less in the misoprostol group. CONCLUSION: Rectal misoprostol is as effective as oxytocin infusion as an adjunct for prevention of postpartum hemorrhage in women with risk factors for uterine atony and is associated with a lower hematocrit drop and blood transfusion postpartum. However, shivering, pyrexia and vomiting are more frequent with misoprostol, though usually self-limited.

Normative references and clinical correlates of fetal umbilical artery Doppler indices in southwestern Nigeria.

OBJECTIVE: To derive normative references for umbilical artery (UA) Doppler indices, including pulsatility index (PI), resistance index (RI), and systolic/diastolic (SD) ratio, for singleton pregnancies in Ile-Ife, Nigeria, and compare them with reference values from other populations. METHODS: A longitudinal study involving 415 women with a singleton fetus at 26-40 gestational weeks attending Obafemi Awolowo University Hospital, Ile-Ife, between July 2015 and March 2019. Fetal UA PI, RI, and SD ratio were measured every 4 weeks until delivery. Reference values from the 2.5th to the 97.5th centiles were derived from 1375 measurements. Correlations between indices and bio-demographic characteristics were assessed; regression equations were generated. RESULTS: The RI, PI, and SD ratio decreased by 0.013, 0.027, and 0.71, respectively, for each additional week of pregnancy. There was a negative correlation between the three indices and birthweight (P<0.001), but not maternal parity, age, or fetal gender. Regression equations for RI, PI, and SD ratio were, respectively, 1.004 - 0.013x, 1.78 - 0.027x, and 4.77 - 0.71x, where x is gestational age (weeks). CONCLUSION: The derived normative references for fetal UA Doppler indices are recommended for monitoring high-risk pregnancies in Nigeria. The indices are comparable to those derived from Norwegian, Thai, and British cohorts.

Factors associated with the desire for companionship during labor in a Nigerian community.

OBJECTIVE: To determine preferences for companionship during labor and to identify associated factors. METHODS: The present prospective cross-sectional survey was conducted at a university teaching hospital in Nigeria between September 1, 2011, and February 28, 2012. Participants included women who underwent the first stage of labor and delivery at the facility, male partners, and healthcare workers from the maternity unit. Data were collected using a pretested questionnaire. RESULTS: There were 226 parturients, 158 male partners, and 69 healthcare workers included in the final analysis; in all, 50 (22.1%) parturients and 37 (23.4%) male partners approved of companionship during labor, whereas 62 (90%) healthcare workers supported it. Among those who approved, a parturient's male partner was stated to be the preferred companion by 33 (66%) parturients, 32 (86%) male partners, and 58 (94%) healthcare workers. The perception of conduciveness of the labor ward for companionship was associated with approving of companionship among both the parturients (adjusted odds ratio [aOR] 2.74) and male partners (aOR 15.79). Previous home delivery (aOR 31.43) and companionship during a previous delivery (aOR 23.00) were also associated with approval. CONCLUSION: Most couples had negative attitudes toward companionship during labor. Intensive education programs and restructuring of facilities could enable Nigerian labor wards to improve the delivery experience for both parturients and their male partners.

Pregnancy-related acute kidney injury requiring dialysis as an indicator of severe adverse maternal morbidity at a tertiary center in Southwest Nigeria.

OBJECTIVE: Despite being a Critical Intervention in the WHO Near-miss concept, the indications and clinical outcomes of patients with Pregnancy-Related Acute Kidney Injury (PRAKI) requiring dialysis at the Obafemi Awolowo University Teaching Hospitals Complex, Nigeria remain unknown. This retrospective review was conducted to facilitate counselling, prognostication and introduction of preventative measures by providing contemporary data on the aetiology and clinical outcomes of women with PRAKI. STUDY DESIGN: A retrospective review. The indications for dialysis and feto-maternal outcomes of women with PRAKI requiring dialysis between January 2007 and December 2016 were reviewed. Analysis was performed with IBM SPSS 21.0. RESULTS: There were 43 patients with PRAKI that required dialysis and 11,242 live births, with Maternal Near Miss Ratio (MNMR) of 3.8/1000 live births. Preeclampsia/ecclampsia (40%), Sepsis (37.5%) and Haemorrhage (20%) were the leading aetiologies of kidney injury, while oligo-anuria (100%) was the commonest clinical presentation. Majority (78%) of them had ≤four dialysis sessions before recovery of renal function. The mean (±SD) gestational age and birth weight at delivery were 36 (±3.1) weeks and 2.9 (±0.6)kg, while the Maternal Mortality Index and Perinatal mortality rates were 18% and 34% respectively. Delayed referral, and lower number of dialysis sessions were the significant predictors of mortality, while four women discontinued care due to cost. CONCLUSION: The high rate of Pregnancy-related acute kidney injury requiring dialysis, with its attendant morbidity and mortality are largely preventable. The prognosis is however good with standardised care. Functional emergency obstetric services, and a review of the Nigerian healthcare financing system are advocated.

Clinical correlates of leiomyoma estrogen and progesterone receptors among Nigerian women.

OBJECTIVE: To compare the expression of estrogen receptor α (ERα) and progesterone receptor (PR) in myometrium and leiomyomata tissue, and to correlate their expression with symptoms of uterine leiomyomata. METHODS: In a cross-sectional study, intraoperative biopsy samples of leiomyomata and adjacent myometrial specimens were obtained from premenopausal women with uterine leiomyomata treated at a center in Nigeria between September 2013 and August 2014. Immunohistochemistry for ERα and PR expression was performed on the samples. The immunoscores of both receptors were correlated with the size and symptoms of the leiomyomata. RESULTS: Among 60 pairs of samples, leiomyomata had a higher mean expression of ERα (H-score 193.42±64.55 vs 153.29±69.13; P=0.01) and PR (214.86±66.56 vs 171.53±63.53; P<0.001) than did myometrial tissues. The tumor diameter correlated negatively with the immunoscores of both receptors irrespective of age, parity, and body mass index, but this was only significant for PR (ρ=-0.44; P<0.001). Downregulation of PR on leiomyomata was predicted to occur at a diameter of 11cm. Menorrhagia, dysmenorrhea, and infertility occurred independently of steroid-receptor expression. CONCLUSION: Leiomyomata seem to depend on steroid hormones, but only during early tumor development. This could have implications for the selection of patients for medical management, especially with steroid-receptor modulators.
