Two hundred and fifty-nine respondents aged older than 18 years completed a standardized, pretested, structured questionnaire as part of activities celebrating World Kidney Day and World Glaucoma Day in 2011. Anthropometric data and blood pressure were recorded, and the data were analyzed using the Statistical Package for Social Sciences version 17.Results: The mean age of the respondents was 49.7 &plusmn; 1.6 years, 100 (38.6%) were males, 84 (32.4%) were farmers, and 111 (42.9%) were traders. The prevalence of hypertension was 13.16% (present in 34 respondents). Seventeen (6.6%) had isolated systolic hypertension, while 11 (4.2%) had isolated diastolic hypertension. Two hundred and thirty-six (91.1%) undertook daily exercise lasting at least 30 minutes and 48 (18.5%) had ever taken antihypertensive drugs on a regular basis. Four respondents (1.6%) claimed a family history of hypertension. The average body mass index (BMI) among respondents was 23.4 &plusmn; 4.9 kg/m2, 51 (19.6%) had a BMI of 25.0&ndash;29.9, and 30 (11.5%) had a BMI &ge; 30. A significant association existed between age older than 40 years and having hypertension (P < 0.05), while no relationship existed between age and BMI or between gender and hypertension (P > 0.05). Rates of older age and high BMI were significantly higher among hypertensives than among normotensives. Respondents with BMI < 25 had at least a three times greater likelihood of developing hypertension than those with BMI < 25 (odds ratio 2.9, 95% confidence interval 0.007&ndash;0.056, P = 0.011).Conclusion: The prevalence of hypertension is high in this study population and we recommend scaling up primary prevention efforts to reduce this in Nigerian communities.Keywords: prevalence, hypertension, anthropometry, body mass index, rural communit

Lymphomas of the female genital tract in Ibadan

Context: Female genital tract cancers are second only to breast malignancies. Cervical cancer is the commonest while epithelial cancers constitute the major histologic type. Lymphoid neoplasms are extremely rare, with the Burkitt's variety accounting for majority of cases seen in the African female.Objective: This is a review of the obstetric/gynaecological patients seen at the University College Hospital, Ibadan between 1976 and 2005, predating the commencement of a nationwide research into non – Hodgkin's lymphoma funded by the Aboderin Foundation.Study Design: Records of subjects were analysed for their  sociodemographic and clinicopathological characteristics, recruiting only those who satisfy the criteria for diagnosing genital tract lymphomas according to Kosari et al1. Retrievable archival paraffin blocks of subjects were also analysed using immunophenotyping.Results: Fifteen cases were identified within the study period; the highest yearly incidence rate being 3 in 1977. In eighteen of the years studied no cases were seen. Most cases (80.0%) occurred in the ovaries. Eighty percent (12) of patients were 25 years or below and nulliparas and grandmultiparas formed 46.7 and 13.4% respectively. Unilateral orbilateral oophorectomy was the commonest surgical procedure (53.3%) while 20.0% had total abdominal hysterectomy with or without bilateral salpingoophorectomy. Data were unavailable concerning use of adjuvanttherapy and outcome of treatment. Four archival paraffin blocks were available for immunophenotyping using the affordable panel of CD20, CD10 and Bcl – 2 antibodies; all were Burkitt's lymphoma.Conclusion: Female genital lymphomas are very rare, affecting the young and nulliparous. The Burkitt's type is commonest

Omics-based molecular techniques in oral pathology centred cancer: Prospect and challenges in Africa

: The completion of the human genome project and the accomplished milestones in the human proteome project; as well as the progress made so far in computational bioinformatics and “big data” processing have contributed immensely to individualized/personalized medicine in the developed world.At the dawn of precision medicine, various omics-based therapies and bioengineering can now be applied accurately for the diagnosis, prognosis, treatment, and risk stratifcation of cancer in a manner that was hitherto not thought possible. The widespread introduction of genomics and other omics-based approaches into the postgraduate training curriculum of diverse medical and dental specialties, including pathology has improved the profciency of practitioners in the use of novel molecular signatures in patient management. In addition, intricate details about disease disparity among diferent human populations are beginning to emerge. This would facilitate the use of tailor-made novel theranostic methods based on emerging molecular evidences

The prevalence of Antithyroglobulin and Antithyroid Microsomal Autoantibodies in Euthyroid Fertile and Infertile Nigerian Women with recurrent spontaneous Abortion and Unexplained Infertility

Plasma levels of antithyroglobulin {TG} and microsomal thyroid peroxidase {TPO} autoantibodies were determined using the ELISA methods, in 87 euthyroid women. These were made up of 44 control women which included 8{18%} nulligravidae, 18{41%} non pregnant multiparous and 18{41%}, pregnant subjects. The infertile groups were made up of 43 women which included 18{42%} with secondary infertility, 17{39%} recurrent spontaneous aborters {RSA} and 8{19%} unexplained {Primary} infertility subjects. The microsomal antithyroid peroxidase and the anti-thyroglobulin auto-antibodies, micro titer mean values, in the infertility subjects were 347.55 units/ml and 35.23 units/ml respectively. These values were higher compared with the micro titer mean values of the control subjects with 284.40 units/ml and 32.51 units/ml respectively. The Micro titer mean value levels of the microsomal antithyroid peroxidase auto-antibodies in the primary infertility group was 437.19 units/ml and in the secondary infertility group was 362.50 units/ml compared with the micro titer mean value of control groups of 284.40 units/ml at

Asymptomatic bacteriuria among elderly and middle-aged rural community-dwellers in South-Western Nigeria

OA Olowe,1 OB Makanjuola,1 KO Olabiyi,1 PO Akinwusi,2 CO Alebiosu,2 MA Isawumi,3 MB Hassan,3 EO Asekun-Olarinmoye,4 WO Adebimpe,4 TA Adewole5 1Department of Medical Microbiology and Parasitology, 2Department of Medicine, 3Department of Ophthalmology, 4Department of Community Medicine, 5Department of Biochemistry, College of Health Sciences, Osun State University, Osogbo, Osun State, Nigeria Abstract: Asymptomatic bacteriuria in elderly individuals has been well described in institutionalized settings, but to a lesser extent in the community. The purpose of this study was to determine the pathogens responsible for asymptomatic bacteriuria in elderly and middle-aged individuals in Alajue-Ede, South-Western Nigeria, and to identify any associated factors. Mid-stream urine samples were collected from apparently healthy elderly and middle-aged volunteers who were participating in community health screening. Samples were processed and bacterial isolates were identified following standard procedures. In total, 128 volunteers (48 men, 76 women) participated in the study. Twenty-eight (22.6%) urinary pathogens were isolated, comprising Klebsiella species in five (17.9%), Pseudomonas aeruginosa in one (3.6%), Escherichia coli in 19 (67.9%), and Proteus species in three (10.7%) cases. Women were identified as being at higher risk of asymptomatic bacteriuria, and the prevalence also increased with increasing age in men. The elderly in this community have a high prevalence of asymptomatic bacteriuria, and screening for comorbid medical conditions may be of benefit.
