The advent of globalization has changed our perspectives radically. It presents increased understanding of world affairs, new challenges and exciting opportunities. The inequitable distribution and use of finite energy resources and global warming are just two examples of challenges that can only be addressed by concerted international collaboration. Globalization has become an increasingly important influence on dentistry and dental education. The International Federation for Dental Educators and Associations (IFDEA) welcomes the challenges it now faces as a player in a complex multifaceted global community. This report addresses the new circumstances in which IFDEA must operate, taking account of the recommendations made by other working groups. The report reviews the background and evolution of IFDEA and describes the extensive developments that have taken place in IFDEA over the past year with the introductions of a new Constitution and Bylaws overseen by a newly established Board of Directors. These were the consequence of a new mission, goals and objectives for IFDEA. An expanded organization is planned using as the primary instrument to facilitate the exchange of knowledge, programmes and expertise between colleagues and federated associations throughout the world, thereby promoting higher standards in oral health through education in low-, middle- and high-income countries of the world. Such aspirations are modified by the reality and enormity of poverty-related global ill health.

Owotade, F, Ogunbodede E, Lawal AA.  2005.  Oral Diseases in the Elderly, A Study in Ile-Ife, Nigeria, 2005/03/01. Journal of Social Sciences. 10:105-110. Abstract

To highlight oral diseases found in an elderly Nigerian population. The records of 494 elderly patients were retrospectively reviewed. The presenting complaints, relevant extraoral and intraoral findings, clinical diagnosis and investigations carried out were recorded. The ages ranged from 55 years to 120 years with almost half (44.0%) in the 60 to 69 year age group. Pain was the commonest presenting complaint (66.2%). Attrition was present in only 8% and was not related to age or sex. Coronal and root surface caries was present in 12.8% and 0.8% respectively and caries was significantly commoner in females and those who were presenting for the first time (p<0.05 and 0.01 respectively). Chronic periodontitis was the most prevalent oral disease (73.9%) and appeared to worsen with age, and decline with the state of the oral hygiene (p<0.05). Denture sore mouth was present in only females (p<0.01). Majority of the elderly (96.0%) had more than 20 teeth while only 16(3.2%) were edentulous. Squamous cell carcinoma was found in 11 patients and it affected significantly more males than females (p<0.05). Significant differences exist in the pattern of oral diseases in Nigeria when compared with the findings in other countries. Such differences might be due to socio-cultural, genetic and environmental factors.

Ogunbodede, E, Lawal O, Lamikanra A, N Okeke I, Rotimi O, A Rasheed A.  2002.  Helicobacter pylori in the dental plaque and gastric mucosa of dyspeptic Nigerian patients, 2002/07/01. Tropical gastroenterology : official journal of the Digestive Diseases Foundation. 23:127-33. Abstract

Presence of helicobacter pylori (H.Pylori) in the dental plaques may be associated with the presence of the same organism in gastric mucosa.To assess and compare the prevalence of H. pylori in dental plaques and gastric mucosa of dyspeptic Nigerians.
Sixty-six consecutive patients undergoing endoscopy for investigation of dyspepsia were included in the study. A predesigned questionnaire was used to collect information on socio-demographic and other factors. Each patient also had clinical dental examination. Dental plaque scrapping was collected before endoscopy for helicobacter pylori culture, and at endoscopy, two gastric biopsy specimens were taken for culture and histology.
The mean age (+/- SD) of the patients was 44.8 (+/- 17.4) years (range 5 to 80 years). The positivity rate of helicobacter pylori in gastric biopsy was 35 of 66 (53.0%) while the same for dental plaque was 46 of 66 (69.7%). The correlation (Spearman's) between gastric mucosa and dental plaque colonization with helicobactor pylori was significant (R = 0.30, P = 0.01). When concordant positivity of gastric biopsy culture and histology was taken as diagnostic, the sensitivity of dental plaque culture was found to be 82.9% and the specificity was 45.2%.
This study revealed that helicobactor pylori has a high prevalence in the dental plaque of the population that we have studied and may therefore be of potential relevance in screening for such infection.

L Ugboko, V, Olasoji O, Ogunbodede E.  1998.  Cervicofacial actinomycosis after partial mandibular resection: Case report, 1998/03/01. East African medical journal. 75:122-3. Abstract

An unusual case of cervicofacial actinomycosis in a 60-year old male Nigerian is reported. The patient had had partial mandibular resection for plexiform ameloblastoma one year earlier with insertion of Kirschner wire to serve as a splint. The authors highlight the possible pathophysiology of this condition. It is suggested that clinicians be aware of the various modes of presentation and natural history of the disease to facilitate prompt diagnosis and appropriate treatment. This will assist in forestalling the numerous complications that may result from actinomycosis.

Ogunbodede, E, Olusile A, Ogunniyi SO, L Faleyimu B.  1996.  Socio-economic factors and dental health in obstetric population, 1996/07/01. West African journal of medicine. 15:158-62. Abstract

The relationship between socio-economic factors and dental health in an Obstetric Nigerian population was studied. The mean gestational age (+/-standard deviation) was 30.16 + 5.45 weeks (range 16-40 weeks). Acquisition of dental education was found to be unrelated to level of education. When the prevalence of dental caries and periodontal disease were considered, the difference between the high, middle and low socio-economic groups were found to be significant (p < 0.05).

This study fabricated and characterized a self-sustaining hydrogenous content clay-polyethylene composite opted for ionizing radiation shielding. Composites designated A–G were fabricated each containing 0–30 wt% of recycled low density polyethylene (LDPE), respectively. To know the effects of the incorporated LDPE on the morphology, microstructural, compressive strength, thermal property and displacement effect on the vital elements were studied using scanning electron microscopy (SEM), X-ray diffractometry (XRD), universal mechanical testing machine, differential thermal analysis (DTA), Rutherford backscattering (RBS) technique and particle induced X-ray emission (PIXE), respectively. The bulk densities of the clay composites ranged between 1.341 and 2.030 g/cm3. The samples’ XRD analysis revealed similar patterns, with a sharp and prominent peak at angle 2θ equals ~26.11°, which matched with card number 16-0606 of the Joint Committee on Powder Diffraction Standards (JCPDS) that represents Aluminum Silicate Hydroxide (Al2Si2O5(OH)4), a basic formula for Kaolin clay. The compressive strength ranged between 2.52 and 5.53 MPa. The ratio of Si to Al in each composite is about 1:1. The dehydroxylation temperature for samples ranged between 443.23 °C and 555.23 °C.

Abstract

An online survey was conducted to identify factors associated with financial insecurity, food insecurity and poor quality of daily lives of adults in Nigeria during the first wave of the COVID-19 pandemic. The associations between the outcome (experience of financial loss, changes in food intake and impact of the pandemic on daily lives) and the explanatory (age, sex, education level, anxiety, depression, HIV status) variables were determined using logistic regression analysis. Of the 4439 respondents, 2487 (56.0%) were financially insecure, 907 (20.4%) decreased food intake and 4029 (90.8%) had their daily life negatively impacted. Males (AOR:0.84), people who felt depressed (AOR:0.62) and people living with HIV -PLHIV- (AOR:0.70) had significantly lower odds of financial insecurity. Older respondents (AOR:1.01) had significantly higher odds of financial insecurity. Those depressed (AOR:0.62) and PLHIV (AOR:0.55) had significantly lower odds of reporting decreased food intake. Respondents who felt anxious (AOR:0.07), depressed (AOR: 0.48) and who were PLHIV (AOR:0.68) had significantly lower odds of reporting a negative impact of the pandemic on their daily lives. We concluded the study findings may reflect a complex relationship between financial insecurity, food insecurity, poor quality of life, mental health, and socioeconomic status of adults living in Nigeria during the COVID-19 pandemic.

Journal of Clinical Hypertension. 23(4) Abstract

Hypertension is one of the most important risk factors for stroke and cardiovascular diseases (CVD) globally. Understanding risk factors for hypertension among individuals with matching characteristics with stroke patients may inform primordial/primary prevention of hypertension and stroke among them. This study identified the risk factors for hypertension among community-dwelling stroke-free population in Ghana and Nigeria. Data for 4267 community-dwelling stroke-free controls subjects in the Stroke Investigative Research and Education Network (SIREN) study in Nigeria and Ghana were used. Participants were comprehensively assessed for sociodemographic, lifestyle and metabolic factors using standard methods. Hypertension was defined as a previous diagnosis by a health professional or use of an anti-hypertensive drug or mean systolic blood pressure ≥ 140 mmHg and/or diastolic blood pressure ≥ 90 mmHg. Logistic regression analysis was used to estimate adjusted odds ratios (aOR) of hypertension and their 95% confidence intervals (CI) at p <.05. Overall, 56.7% of the participants were hypertensive with a higher proportion among respondents aged ≥60 years (53.0%). Factors including physical inactivity (aOR: 9.09; 95% CI: 4.03 to 20.53, p <.0001), diabetes (aOR: 2.70; CI: 1.91 to 3.82, p <.0001), being ≥60 years (aOR: 2.22; 95% CI: 1.78 to 2.77, p <.0001), and family history of CVD (aOR 2.02; CI: 1.59 to 2.56, p <.0001) were associated with increased aOR of hypertension. Lifestyle factors were associated with hypertension in the current population of community-dwelling stroke-free controls in west Africa. Community-oriented interventions to address sedentary lifestyles may benefit this population and reduce/prevent hypertension and stroke among them.

Journal of Stroke and Cerebrovascular Diseases. 30(10) Abstract

Background: Stroke risk can be quantified using risk factors whose effect sizes vary by geography and race. No stroke risk assessment tool exists to estimate aggregate stroke risk for indigenous African. Objectives: To develop Afrocentric risk-scoring models for stroke occurrence. Materials and Methods: We evaluated 3533 radiologically confirmed West African stroke cases paired 1:1 with age-, and sex-matched stroke-free controls in the SIREN study. The 7,066 subjects were randomly split into a training and testing set at the ratio of 85:15. Conditional logistic regression models were constructed by including 17 putative factors linked to stroke occurrence using the training set. Significant risk factors were assigned constant and standardized statistical weights based on regression coefficients (β) to develop an additive risk scoring system on a scale of 0–100%. Using the testing set, Receiver Operating Characteristics (ROC) curves were constructed to obtain a total score to serve as cut-off to discriminate between cases and controls. We calculated sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) at this cut-off. Results: For stroke occurrence, we identified 15 traditional vascular factors. Cohen's kappa for validity was maximal at a total risk score of 56% using both statistical weighting approaches to risk quantification and in both datasets. The risk score had a predictive accuracy of 76% (95%CI: 74–79%), sensitivity of 80.3%, specificity of 63.0%, PPV of 68.5% and NPV of 76.2% in the test dataset. For ischemic strokes, 12 risk factors had predictive accuracy of 78% (95%CI: 74–81%). For hemorrhagic strokes, 7 factors had a predictive accuracy of 79% (95%CI: 73–84%). Conclusions: The SIREN models quantify aggregate stroke risk in indigenous West Africans with good accuracy. Prospective studies are needed to validate this instrument for stroke prevention.
