(Informa Healthcare USA, Inc, 2008) Akinwuntan, A. I.; Adesina, O. A.; Okolo, C. A.; Oluwasola, O. A.; Oludokun, A.,; Ifemeje, A. A.; Adewole, I. F.
The prevalence of squamous intraepithelial lesion is higher among human immunodeficiency virus (HIV)-positive women. These lesions when they occur in these patients are also more difficult to treat. A total of 205 consenting HIV-seropositive women were recruited. A cervical cytology (Pap smear) was taken, followed by visual inspection with freshly prepared 5% acetic acid and cervical biopsy taken from the squamocolumnar junction as the reference for diagnosis to avoid verification bias. The sensitivity of VIA was 76.0% (95% CI 52.0-91.0); specificity 83.0% (95% CI 77.0-88.0); positive predictive value 34.0% (95% CI 21.0-49.0). The sensitivity of cervical cytology (Pap smear) was 57.0% (95% CI 34.0-77.0), specificity of 95.0% (95% CI 90.0-97.0), and positive predictive value of 55.0% (95% CI 33.0-75.0). In HIV-seropositive women, the sensitivity of VIA is 76.0%, making it a useful screening test for preinvasive lesion of the cervix in low resource settings.
Knowledge dissemination and evaluation in a cervical cancer screening implementation program in Nigeria
(Elsevier Inc., 2007) Miller, D.; Okolo, C. A.; Mirabal, Y.; Guillaud, M.; Arulogun, O. S.; Oladepo, O.; Crain, B.; Follen, M.; Adewole, I. F.
Objectives: Our goals were to train health professionals in Nigeria using the text, "Planning and Implementing Cervical Cancer Prevention and Control Programs: A Manual for Managers", and then evaluate the knowledge dissemination process using a pre- and post-test assessment. The manual was developed by the ACCP, WHO, TARC, PATT-T,Engender Health, TI-TPTEGO, and PAT-TO with funding from the Gates Foundation. It is an inclusive guide to implementation and maintenance of screen-and-treat cervical cancer prevention clinics and is ideally suited for programs operating in the developing world. Methods. Training took place at a conference in Ibadan, Nigeria. Participants included teams of physicians, nurses, bioengineers, data managers, and administrators who met in joint and parallel sessions to "train the trainers". This meeting was designed to provide both training and equipment to personnel to be involved in the implementation of a cervical cancer control initiative in Nigeria. A 36 item pre-test was administered prior to a group study sessions. A slide presentation summarized salient points before the post-test was given. The results were entered into an MS Excel spreadsheet for descriptive statistics about (I) the participants, (2) the test, (3) an examination of profession, years of work experience, years of education, and gender as predictors of two outcomes (low pre-test score and large difference between pre- and post-tests) and (4) overall performance on the exam. Results. There were 70 participants and trainers, of which 53 took the exam. Most of the examinees were physicians. Some participants did not fill out the post-test, leaving their tests inevaluable. A closer look at the test revealed eight questions that were confusing and nine that were too easy. All participant subgroups performed better on the post-test than the pre-test; the improvements were statistically significant. While profession impacted the results, profession was not statistically significant. Years of work experience, years of education, and gender did not affect test results. Conclusions. While the study suffers from a small sample size, a few ambiguous questions, and the need for pilot testing the instrument prior to the meeting, the report evaluates the manual very favorably. The authors showed a significant gain in knowledge. The manual gives "the big picture" and does so with clarity. The text and supplementary material outline the work that needs to proceed in an organized program, and the material was easily understandable in Nigeria. Future evaluations could benefit from more participants and varied learning structures.
Knowledge of the human papilloma virus vaccines, and opinions of gynaecologists on its implementation in Nigeria
(Women’s Health and Action Research Centre, 2013) Morhason-Bello, I. O.; Adesina, O. A.; Adedokun, B. O.; Awolude, O.; Okolo, C. A.; Aimakhu, C. O.; Akinwunmi, B. O.; Oladokun, A.; Adewole, I. F.
The objective of this study was to determine the knowledge and perception of Nigerian Obstetricians and Gynaecologists towards human papilloma virus vaccine use in Nigeria. A cross sectional study was conducted amongst participants that attended the 42nd Society of Gynaecology and Obstetrics of Nigeria. The findings revealed that 44.5% knew the correct HPV vaccine schedule. Regarding implementation in Nigeria, 87.4% suggested its incorporation into the national immunization program and about a third agreed that it should be a precondition for school enrollment. Regression analysis showed that senior residents were more likely to have adequate knowledge of the vaccine compared to junior residents (AOR 7.181 95% CI OR=1.792 – 28.782). We conclude that the knowledge of eligibility and schedule is poor. It is recommended that adequate information should be provided to this group of health workers because of their strategic position in its implementation in Nigeria.

Low field MR imaging of sellar and parasellar lesions: Experience in a developing country hospital
(2011) Ogbole, G. I; Adeyinka, O. A.; Okolo, C. A.; Ogun, A. O.; Atalabi, O. M.
Background: Magnetic resonance imaging (MRI), an advancement which followed computed tomography (CT) is expensive and inaccessible in most dveloping countries. However it is the procedure of choice in evaluating sellar and parasellar lessions. Its major advantages are its superior soft tissue contrast differentiation, its capacity for multiplanar imaging and nonexistence of ionising radiation. Its use is relatively new in Nigeria, a developing economy in Africa. Since its introduction in 2005, it has been utilised extensively for neuroimaging at the University College Hospital (UCH), Ibadan; a large hospital is south-western Nigeria. Objective: To review the role and pattern of low field MR imaging in sellar and parasellar lesions presenting to a tertiary care centre in Nigeria. Methods: All 62 patients with clinically suspected sellar and parasellar masses, referred to the department of Radiology, UCH Ibadan for MRI between December 2006 and January 2010 were retrospectively analysed. The examinations were performed using an open 0.2T permanent magnet MR unit. T1W, T2W,T2/ FLAIR, TOF and T1W post gadolinium DTPA sequences of the sellar region were obtained. Result: Of the 62 patients, there were 27 males and 35 females. The modal age group was 40-49 years with a mean age of 39.94 years (±16.65years). Twenty-four cases (38.7%) had histological daignosis, of which 20(83.3%) were consitent with initial MRI diagnosis. Pituitary adenomas were the commonest (58.06%) lesions of the sellar and parasellar regions. Others include parasellar meningiomas, cranipharyngiomas, and gaint aneurysms. Headache and visual impariment were the major presenting features and showed no significant correlation with tumor size. Conclusion: The use of low filed MRI in the diagnostic evalauation of patients with suspected sellar or parasellar lesions in developing countries of low economic resource is commendable as it provides beneficial outcomes in management.
Pediatric head and neck malignancies in sub-Saharan Africa
(2012) Adeyemo, A. A.; Okolo, C. A.
Introduction: Cancers are relatively rare in children however recent reports suggest that malignancies are becoming a major source of pediatric deaths. Method: Using the database of the cancer registry of the University College Hospital, Ibadan we reviewed all newly diagnosed cases of head and neck cancers in children under 19years old at the hospital between 1981 and 2008. Results: A total of 1,021 cases of Head and Neck cancers were seen in children. The hospital based incidence of pediatric head and neck cancers is 36 cases per year. There were 627 males and 394 females [M:F ratio of 1.6:1] with mean ages of 8.21 and 7.70 years respectively. Boys were more affected than girls in all years of life while the peak age of onset for both sexes is the third year of life. The commonest anatomical site involved is the eye/orbit; other common sites were the nasopharynx, paranasal sinuses, nasal cavity and thyroid gland. Neural malignancies constitute the commonest malignancies seen (35.3%), other are lymphomas (33.1%), squamous cell carcinoma (9.1%) and soft tissue sarcoma (8.6%). Retinoblastoma is the commonest lesion seen among the patients with a slight male preponderance [M:F ratio of 1.2:1] Burkitt lymphoma (BL) is seen in all age groups but there is greater frequency in the older ages. The incidence of carcinomas is higher in the older age groups, relatively rare lesions like Hodgkins lymphoma and thyroid malignancies are almost exclusive to older children. Conclusion: The pattern of head and neck malignancies in children in sub-Saharan Africa is changing; dominant lesions like lymphomas are being gradually replaced by other malignancies such as neural malignancies, soft tissue sarcomas and squamous cell carcinoma
A review of vulvar and vaginal cancers in Ibadan, Nigeria
(2013) Okolo, C. A.; Odubanjo, M. O.; Awolude, O. A.; Akang, E. E. U.
The objectives of this study are to give an update on the previous studies on vulvar and vaginal cancers from the University College Hospital (UCH), Ibadan, Nigeria, to elucidate any changes in pattern, and to enumerate some of the factors affecting the management of these cancers at the UCH today. All the cases of cancer of the vulva and vagina seen at the UCH between January 1981 and December 2008 were reviewed and re-classified according to the World Health Organization (WHO) histological classification of 2004. The results are as follows: Vaginal and vulvar cancers were the 4th (1.4%) and 5th (1.2%) most common of the 5913 gynecological cancers seen. The mean age was 49.7 years. Squamous cell carcinoma (SCC) was the most common histological type. Notably, vulvar cancer is more common than vaginal cancer in the US and the UK and this opposes our findings. We studied time periods before and after the year 2000, and found vaginal cancer to be more common before and vulvar cancer after the year 2000. We suggest that this may be related to the introduction of the FIGO guidelines in 2000. We conclude that it is important to strictly adhere to the FIGO guidelines in determining the primary site of origin of these cancers in patients with advanced local disease as this distinction has implications for clinical management.
