Human Immunodeficiency Virus (HIV) Seropositivity In African Patients Presenting To The Eye Clinic - A Preliminary To Prevention Of Occupational Exposure
CO Adeoti, AO Ashaye, MA Isawumi
African Journal of Clinical and Experimental Microbiology , 2008,
Abstract: A seroprevalence study of Human immunodeficiency virus (HIV) infection in new patients attending the eye clinic of LAUTECH Teaching Hospital in Osogbo, Osun State, Nigeria showed that twenty-nine patients 2.7%) were positive to HIV1. No patient was positive to HIV 2. There were 21 males (72.4%) and 8 females (27.6%). The clinical diagnosis in the HIV positive patients was as shown in Table 1. Cataract was found in nine cases (31.03%), herpes zoster 4 (13.79%), glaucoma, optic atrophy (nonglaucomatous) and corneal abscess were responsible for 3 (10.35%) of cases each; presbyopia, bacterial conjunctivtis 2 (6.89%) while maculopathy, orbital cellulitis and adherent leucoma were found in 1 (3.45%) patient each. These findings suggest that, patients with ocular disorders and who are otherwise healthy looking may infact be HIV seropositive and as such it may be necessary to observe all rules relating to HIV transmission so as to prevent occupational exposure and cross infection in our clinics and operating theatres. Necessary measures to reduce occupational HIV infection and post exposure treatment if exposure occurs are discussed.

Abstract: nterior segment of the eye in diabetes Original Research (2528) Total Article Views Authors: Adeoti CO, Isawumi MA, Ashaye AO, Olomola BV Published Date May 2012 Volume 2012:6 Pages 667 - 671 DOI: http://dx.doi.org/10.2147/OPTH.S27313 Received: 13 October 2011 Accepted: 11 December 2011 Published: 07 May 2012 CO Adeoti1, MA Isawumi1, AO Ashaye2, BV Olomola1 1Ladoke Akintola University of Technology Teaching Hospital, Osogbo, Nigeria; 2Ophthalmology Department, University College Hospital, Ibadan, Nigeria Purpose: A prospective study to examine the anterior segment of the eye in patients with diabetes mellitus. Materials and methods: The anterior segments of the eyes of 181 patients with diabetes mellitus were examined. The commonest finding in the lids was warts, followed by poliosis and chalazia, and, in the conjunctiva, tortuous conjunctival vessels inferiorly (36.50%), pterygium (14.92%), and pingueculum (14.37%). Corneal sensitivity was reduced in 25 (13.80%) patients. Iris atrophy was the commonest finding in the iris. Dilatation of the pupil was delayed in 34 (18.79%) patients. Cataract was found in 119 (65.75%) patients. Forty-one (22.65%) patients had intraocular pressure greater than 21 mmHg. Seven (3.87%) patients, four (2.21%) patients, and one (0.55%) patient had seventh, third, and fourth palsy, respectively. No patient had sixth nerve palsy. Conclusion: Primary care physicians and other allied health care professionals who are first in contact with patients are enjoined to familiarize themselves with the anterior segment features of diabetes mellitus and take necessary action when they are detected.

Abstract: EO Asekun-Olarinmoye,1 PO Akinwusi,2 WO Adebimpe,1 MA Isawumi,3 MB Hassan,3 OA Olowe,4 OB Makanjuola,4 CO Alebiosu,2 TA Adewole51Department of Community Medicine, 2Department of Medicine, 3Department of Surgery, 4Department of Microbiology, 5Department of Chemical Pathology, College of Health Sciences, Osun State University, Osogbo, Osun State, NigeriaBackground: The purpose of this study was to determine the prevalence of hypertension in two rural communities of Osun State, Nigeria.Methods: A consenting adult population of the Alajue and Obokun rural communities in southwestern Nigeria that presented for the screening exercise participated in this community-based cross-sectional descriptive study. 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 ± 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 ± 4.9 kg/m2, 51 (19.6%) had a BMI of 25.0–29.9, and 30 (11.5%) had a BMI ≥ 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 0.007–0.056, 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 community

Sierra Leone Journal of Biomedical Research , 2011,
Abstract: Female genital mutilation with its attendant complications has been a harmful traditional practice that is difficult to eliminate despite all efforts by various government and non-governmental agencies in Nigeria. The aim of this study is to assess the experience and the knowledge of the health workers practicing in our environment on Female genital cutting (FGC). Two hundred and fifty were interviewed with self-administered structured questionnaire. Their mean age was 35.2±8.3 years. Type I 82(66.6%) was the commonest FGC seen by the health workers, type II 31(25.2%), type III 9 (7.3%) and type IV constituted 0.8%. Two hundred and two (202) (80.0%) of the respondents admitted to having sufficient knowledge in preventing FGC while 42 (16.8%) did not have. One hundred and twenty one (121) (48.4%) had been asked to perform FGC. It was concluded that female genital cutting is still a major health problem in Nigeria. There is need for all concerned to step up efforts in the elimination of the practice.

AS Adeyemi, S E Akinola, A I Isawumi
Nigerian Journal of Clinical Practice , 2007,
Abstract: We report a case of successful myomectomy in pregnancy. The patient, a 27 year old nulliparous, presented with 2 year history of progressive abdominal swelling and 13 weeks of amenorrhoea. Abdomino-pelvic ultrasonography revealed a viable intrauterine pregnancy at 18 weeks and 3 days; there was also a huge mass with cystic component, extending from the pelvis to the whole of the abdomen, with associated dilatation of the renal calyces bilaterally; sonographic diagnosis of ovarian mass in pregnancy was made. At exploratory laparotomy, a huge subserous leiomyoma coexisting with pregnancy was found; myomectomy was done. The rest of the pregnancy was uneventful, and the patient had spontaneous vertex delivery of a live infant at term.

African Journal of Biotechnology , 2008,
Abstract: The antimicrobial activity of extracts of twelve Nigerian medicinal plant species and a “wonder cure” concoction (Epa –Ijebu) used in traditional medicine for the treatment of tuberculosis and cough were screened for activity against Mycobacterium tuberculosis isolated from tuberculosis patient sputum and the control strains of M. tuberculosis (H37RV). Both ethanolic and aqueous solution of the extract of Allium ascalonicum, Terminalia glaucescens, Allium cepa and Securidaca longepedunculata (ethanolic extract only) at 0.05 g/ml as well as aqueous solution of “wonder cure” concoction at same concentration inhibited the growth of M. tuberculosis. The phytochemical analysis of the plant extract and the Epa-Ijebu showed the presence of bioactive compounds: tannin, flavonoid, alkaloids, phylobatanin, anthocyanin, reducing sugar, saponin and anthraquinone. Our results offer a scientific basis for the traditional use of aqueous and ethanolic extracts of A. ascalonicum, T. glaucescens, A. cepa, S. longepeducunlata (ethanolic extract only) and aqueous solution of the “wonder cure” concoction against M. tuberculosis. However local herbs such as Nicotiana tabacum, Allium sativum, Aframomum melegueta, Aprus precatorius, Xylopia aethiopica, Tetrapleura tetraptera, Crinium jagus, and Garcinia kola were ineffective in vitro.

Annals of African Medicine , 2006,
Abstract: Background / Purpose : To assess the prevalence and identify the causes of eye diseases among students in Ilesa east local government area, in south-western Nigeria, so that prevention strategies could be mapped out. Methods : A cross-sectional survey that utilised a multi-stage random sampling method to select 1144 primary and secondary students comprising 504 males and 640 females. Their ages ranged from 4 to 24 years. Majority (97.8%) were below 18 years of age. Results : A total of 177 (15.5%) of the school children were found to have eye diseases. These included conjunctival diseases (8%) constituted mainly by allergic/vernal conjunctivitis (7.4%), refractive error (5.8%), lid disorders (0.6%), squint (0.3%), corneal scarring (0.3%) and cataract (0.2%). Conclusion : Eye diseases are common amongst school children. Health education will go a long way in the prevention of ocular diseases amongst school children. Wearing of corrective glasses should be emphasised for children with refractive error.Eye examination for all new intakes into both public and private primary and secondary schools is advocated.This will allow for early detection and prompt treatment of eye diseases in the young, which will go a long way in reducing ocular morbidity and unnecessary blindness.
Improvements and Generalizations of Stochastic Knapsack and Multi-Armed Bandit Approximation Algorithms: Full Version
Will Ma
Computer Science , 2013,
Abstract: The multi-armed bandit (MAB) problem features the classical tradeoff between exploration and exploitation. The input specifies several stochastic arms which evolve with each pull, and the goal is to maximize the expected reward after a fixed budget of pulls. The celebrated work of Gittins et al. [GGW89] presumes a condition on the arms called the martingale assumption. Recently, A. Gupta et al. obtained an LP-based 1/48-approximation for the problem with the martingale assumption removed [GKMR11]. We improve the algorithm to a 4/27-approximation, with simpler analysis. Our algorithm also generalizes to the case of MAB superprocesses with (stochastic) multi-period actions. This generalization captures the framework introduced by Guha and Munagala in [GM07a, GM07b], and yields new results for their budgeted learning problems. Also, we obtain a (1/2-eps)-approximation for the variant of MAB where preemption (playing an arm, switching to another arm, then coming back to the first arm) is not allowed. This contains the stochastic knapsack problem of Dean, Goemans, and Vondrak [DGV08] with correlated rewards, where we are given a knapsack of fixed size, a set of jobs each with a joint distribution for its size and reward, and the objective is to maximize expected reward before the knapsack size is exhausted. Our (1/2-eps)-approximation improves the 1/16 and 1/8 approximations of [GKMR11] for correlated stochastic knapsack with cancellation and no cancellation, respectively, providing the first tight algorithm for these problems that matches the integrality gap of 2. We sample probabilities from an exponential-sized dynamic programming solution, whose existence is guaranteed by an LP projection argument. We hope this technique can also be applied to other dynamic programming problems which can be projected down onto a small LP.
