Hepatitis B and C in doctors and dentists in Nigeria
(Oxford University Press, 1997) Olubuyide, I. O.; Ola, S. O.; Aliyu, B.; Dosumu, O. O.; Arotiba, J. T; Olaleye, O. A.; Odaibo, G. N.; Odemuyiwa, S. O.; Olawuyi, F.
"We surveyed a random sample (n=75) of doctors and dentists at University College Hospital, Ibadan, Nigeria. They were offered anonymous testing for hepatitis B surface antigen (HBsAg), hepatitis B antibodies to hepatitis B core antigen (anti-HBc) and to hepatitis C virus (anti-HCV) by enzyme immunoassay. The results suggest a high prevelance of hepatitis B virus (HBV) with a high potential of transmissibility, as well as a high prevalence of HCV infection. The majority of the doctors and dentist use universal precaution for protection against viral hepatitis on <50% of the occasion when they carry out procedures on their patients. Infection with HBV was associated with type of specialty (surgeaon, dentists) and lack of HBV vaccination (p<0.05). After logistic regression, these factors, were independently associated. with HBV infection (p<0.05). Sixty (80%) had not hepatitis received prior HBV vaccination. Unvaccinated personnel were more likely to be surgeons, dentists, <37 years of age, and have fewer years of professional activity (p<0.05). After logistic regression, only fewer years of professional activity remained independently associated with lack of vaccination (p<0.05). To reduce the occupational exposure of doctors and dentists use universal precaution must be rigorously adhered to when the doctors and dentists carry out procedures on their procedures on their patients, and all health-care workers should be vaccinated with HBV vaccine and the HCV vaccine, when it becomes available."
Isolation of 3-(4-hydroxyphenyl) methylpropenoate and bioactivity evaluation of Gomphrena celosioides Extracts
(IfADo - Leibniz Research Centre for Working Environment and Human Factors, 2010) Dosumu, O. O.; Idowu, P. A.; Onocha, P. A.; Ekundayo, O.
The efficacy of Gomphrena celosioides extracts in traditional medicine in the treatment of infectious diseases was evaluated by biological assays. The bioactivities of the extracts of this plant were tested against organisms. The ethyl acetate and methanol extracts of the plant dis played inhibition activities on Staphylococcus aureus, Bacillus subtilis, Pseudomonas aeruginosa, Escherichia coli and Salmonella typhi. Methanol extract was active against Candida albicans, Aspergillus niger and Trichophyton species with diameter zones of inhibition between 14 and 20 mm. Fractionation of the methanol extract produced 3-(4-hydroxyphenyl) methylpropenoate with mild antimicrobial activity against the test microorganisms. The anthelmintic assay showed ethyl acetate and methanol extracts to be active against Fasciola gigantica, Taenia solium and Pheretima pasthuma. Ethyl acetate was the most toxic of the extracts causing paralysis of Taenia solium within 15 minutes and the death of Fasciola gigantica within 20 minutes of application. The brine shrimp assay gave an LC50 of 52.15 and 77.98 µg/ml on hexane and methanol extracts respectively. The result of this work corroborated the folkloric use of Gomphrena celosioides in the treatment of infectious diseases.
Quality of records keeping by undergraduate dental students in Ibadan, Nigeria
(2012-06) Dosumu, E. B.; Dosumu, O. O.; Lawal, F. B.
Background: Recording the interaction between a patient and the dentist is of primary importance in dental practice. The completeness of recordings of undergraduate students, often inadequate, has been found to subsequently impact on the quality of dental care offered by professionals. Once identified, correcting the inadequacies has also been shown to improve the quality of dental practice. Objective: We aimed to evaluate the quality of records keeping by dental students in Ibadan, Nigeria. Method: A retrospective review of records of patients seen by dental students, at the clinics of the dental school in Ibadan, Nigeria, over a six months period was conducted. The charts were reviewed for: demographic data, medical and dental history, clinical findings, diagnosis, treatment plan and note on informed consent. Assessment of the quality of data obtained was done using a modified CRABEL’s scoring system. Results: A total of 318 case files were retrieved for this study. The median modified CRABEL score was 95%, with a range of 65 to 95%. Eighty-two recordings (25.2%) had a score < 90%, while 236 recordings (74.2%) had a score > 90%. The most frequently unrecorded data was written consent in all the charts, followed by procedure done with the documentation absent in 20.4%. All the supervisors signed at the end of the consultation. Conclusion: The quality of records keeping by dental undergraduates is fair but there is a need to emphasize deficient areas and improve upon the quality of record keeping
