Evaluation of anticaries activity of selected mouthwash marketed in Nigeria
(Pharmacotherapy Group,, 2010) Oluremi, B. B.; Osungunna, M. O.; Idowu, O. A.; Adebolu, O. O.
Purpose: This work was aimed at evaluating four brands of mouthwash marketed in Nigeria for their anticaries activity. Method: The susceptibility pattern of bacterial isolates obtained from 30 patients having carious teeth to the selected mouthwash was determined using the cup-plate method. The zones of inhibition produced by the mouthwash against the bacterial isolates were measured to determine the degree of susceptibility. Results: The organisms isolated from the patients were Staphylococccus aureus, Klebsiella sp, Streptococcus sp, Escherichia coli and Pseudomonas aeruginosa in the following proportions: 30, 27, 20, 17 and 7 %, respectively. Anticaries evaluation revealed that 0.047 % thymol in ethanol displayed the highest degree of anticaries activity against all the Streptococcal species tested. Incorporation of preservatives in mouthwashes may adversely affect their anticaries activity as indicated by the fact that the preserved mouthwash exhibited lower activity than the unpreserved mouthwash. Conclusion: Anticaries activity is optimally achieved by using appropriate mouthwash combinations as this prevents both the initiation and progression of dental caries. The use of preservatives in mouthwash formulations should be done with caution as this may interfere with mouthwash activity.
A study of the availability and utilisation of library electronic resources by undergraduate students in private Universities in Ogun state, Nigeria
(2014-09) Quadri, G.; Adetimirin, A. E.; Idowu, O. A.
The degree of availability and utilization of e-resources in any university library may influence the information services provision to students. The main objective of the study was to investigate the availability and utilization of e-resources by undergraduate in selected private university libraries in Ogun State, Nigeria. Descriptive survey design was adopted and study population consisted of 9700 undergraduates from Babcock and Redeemer’s universities. Simple random was used to select a sample of 291 and the questionnaire was the main instrument used for data collection. Data were analyzed using SPSS specifically descriptive statistics consisting of tables of frequency and percentage. The findings revealed that the internet was readily available in Babcock (83.5%) and Redeemer (92.8%), while other e-resources were not readily available. Most of the respondents in Babcock (64.0%) and Redeemer (89.1%) used the e-resources for assignment and research/project. Poor internet connectivity, lack of relevant e-resources in various disciplines, erratic power supply, and lack of technical know-how were the major challenges faced by the respondents. The internet and e-journals are important sources of information for both universities undergraduate students. Also, the availability and use of e-resources has no doubt contributed meaningfully to the information acquisition for class work, assignment and research needs of the students.
WHO classification of meningiomas–A single institutional experience
(Elsevier Masson/Elsevier BV, 2020) Salami, A. A.; Idowu, O. A.; Akanji, A. M.; Onakpoma, F.
Introduction Meningiomas are among the most common intracranial neoplasms worldwide. The World Health Organization (WHO) has classified the neoplasm into three grades, with each grade having several histological variants. Several studies conducted in Black populations have shown differences compared with Caucasian populations regarding the occurrence of histological variants. Our study sought to examine the histological variants of meningioma seen in a predominantly Black population using the WHO grading system. Methods We conducted a retrospective study of all meningiomas seen in our hospital facility over a twenty-year period. Data from all patients diagnosed with meningioma, who also had surgical biopsies taken, were analyzed. The meningiomas were graded using the WHO grading system and classified into different histological variants within each grade as described by the WHO study group. Results The study included a total of 163 biopsies. There were more females diagnosed with meningiomas, with a female-to-male ratio of 1.4. Most of the tumors were grade one; however, there were more males with malignant meningiomas. Transitional meningiomas were the most commonly seen variants among the grade one tumors, while atypical and anaplastic variants were most common in grades two and three, respectively. Conclusion A larger population-based study is needed to provide epidemiological data on the occurrence of meningiomas in Black populations.
