Comparative performance of HbA1c 6.5% for FPG ≥ 7.0 vs 2hr PG≥ 11.1 criteria for diagnosis of Type 2 diabetes
AN Adamu
African Health Sciences , 2011,
Abstract: Background: International expert committee on the use of HbA1c to diagnose diabetes mellitus in 2009 and World Health Organization (WHO) in 2011 has advocated the use of HbA1c to diagnose diabetes mellitus. Objective: To determine and compare the relationship between the new cut off value of HbA1c with established criteria. Methods: Thirty-one hypertensive subjects attending Lagos University Teaching Hospital were recruited for HbA1c and standard oral glucose tolerance test. Fasting plasma glucose (FPG) and two-hour plasma glucose (2hrpp) value of e”126mg/dl and >200mg/dl were used as standard respectively for diagnosis of diabetes. The HbA1c of e”6.5% was used to diagnose diabetes. The performance and correlation of HbA1c with FPG and 2hrpp were calculated and results were compared. Results: Mean age of the subjects was 53.97±6.27years. The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), efficiency and correlation of FPG is 50%, 68%, 27%, 85%, 64% and 0.5 respectively while the sensitivity, specificity, PPV, NPV, efficiency and correlation of 2hrpp is 73.91%, 62.5%,85%, 41.66%, 70.97% and 0.73% respectively. There was a significant difference between FPG and 2hrpp interms of sensitivity, PPV and NPV. Conclusion: The results of HbA1c with 2hrpp has better correlation, sensitivity, and PPV compared to HbA1c with FPG.

Abstract: ilical metastasis of unknown primary presenting as umbilical hernia: a case report Case report (3189) Total Article Views Authors: Ibrahim W Adamu, Noubar Kevorkian, Genato Romulo, et al Published Date November 2010 Volume 2010:2 Pages 127 - 129 DOI: http://dx.doi.org/10.2147/PLMI.S13467 Ibrahim W Adamu1, Noubar Kevorkian1, Genato Romulo1, Stephen S Carryl1, Armand Asarian1, Philip Q Xiao2 1Department of Surgery, 2Department of Pathology, The Brooklyn Hospital Center, Brooklyn, NY, USA Abstract: Umbilical metastasis is well known to be a late stage of malignancy and is associated with a poor prognosis. The majority of such cases are associated with primary gastrointestinal and gynecologic malignancies, and fewer cases are noted to derive from the thoracic cavity and the urinary tract. In this report, we describe a rare case of metastasis that presented as incarcerated umbilical hernia with no primary sites found. Extensive work-up, including tumor markers, imaging studies, endoscopies, and immunohistochemical analysis, failed to identify the primary source of this malignancy; this was a rare case of Sister Mary Joseph’s nodule with unknown primary. Therefore, it is very important for a surgeon to consider metastasis among the differential diagnosis of umbilical hernia.

Modeling the Transmission Dynamics of the Monkeypox Virus Infection with Treatment and Vaccination Interventions  [PDF]
Sulaiman Usman, Ibrahim Isa Adamu
Journal of Applied Mathematics and Physics (JAMP) , 2017, DOI: 10.4236/jamp.2017.512191
Abstract: Presently, an ongoing outbreak of the monkeypox virus infection that began in Bayelsa State of Nigeria has now spread to other parts of the country including mostly States in the South-South with the Nigerian Ministry of Health confirming 4 samples out of the 43 sent for testing at WHO Regional Laboratory in Dakar, Senegal. This reminds us that apart from the eradicated smallpox, there are other poxviruses that pose potential threat to people in West and Central Africa. In this paper, we developed a mathematical model for the dynamics of the transmission of monkeypox virus infection with control strategies of combined vaccine and treatment interventions. Using standard approaches, we established two equilibria for the model namely: disease-free and endemic. The disease-free equilibrium was proved to be both locally and globally asymptotically stable if R0 < 1 using the next-generation matrix and the comparison theorem. While the endemic equilibrium point existed only when R0 > 1, was proved to be locally asymptotically stable if R0 > 1 using the linearization plus row-reduction method. The basic reproduction numbers for the humans and the non-human primates of the model are computed using parameter values to be R0,h = 9.1304 x 10-6 and R0,n = 3.375 x 10-3 respectively. Numerical simulations carried out on the model revealed that the infectious individuals in the human and non-human primates’ populations will die out in the course of the proposed interventions in this paper during the time of the study. Sensitivity analysis carried out on the model parameters shows that the basic reproduction numbers of the model which served as a threshold for measuring new infections in the host populations decrease with increase in the control parameters of vaccination and treatment.

Shehu Usman Adamu, D. McGill
Journal of Tuberculosis Research (JTR) , 2018, DOI: 10.4236/jtr.2018.61003
Abstract: A study was conducted in Kaduna State Nigeria to ascertain the impact of Drug Supply and laboratory services towards effective functioning of DOTS system. Six DOTS providing centres were identified for the study and in each centre, three respondents were selected based on their profession, the Medical Officer, the Pharmacist and the Laboratory Technician totaling 18. The officers were interviewed for the purpose of the research. Semi structured Interviews were conducted in this research as a means of obtaining Health workers perspective. The Interview which was conducted in their respective work station was open ended and all questions are same for all respondents. During the course of the study, all respondents agreed that the sources of drugs supply to their respective centres was the Kaduna State Tuberculosis and leprosy control Program office from the state capital and that drugs are been supplied quarterly and are adequate with slight interruption due to Logistic while for Laboratory services the respondents were of the view that there is the need to improve on it as there are cases of shortage of reagents and erratic supply of Electricity for effective Laboratory functioning.

Abstract: Background: The magnitude and causes of eye diseases in Ethiopia has been derived from small scale studies. This information became no longer useful in tracking the success of intensified efforts in preventing and controlling avoidable causes of blindness and eye diseases in line with the goals of Vision 2020: The Right to Sight. Objective: The national household survey was conducted primarily to provide national and regional state level estimates of low vision, blindness and trachoma. The secondary aims include describing the major causes of low vision and blindness. Methods: The national survey utilized cross sectional epidemiological study design with multistage sampling strategy. All nine regional states and two city administrations of the country were involved in the survey. Sample size and sampling strategies were developed taking into account population size of the regional states. Visual acuity was tested using the LogMar chart and trachoma grading was done following the WHO grading system. The cause of low vision and blindness were determined by ophthalmologists. Results: A total of 174 clusters, 6056 households and 30022 individuals were involved in the survey. Of the total 30022 individuals 25650 (85.4%) were present and examined by the survey team. Implementing quality control supervision in the very remote clusters was a major challenge. About 55% of the survey clusters were within 10 Km of health facility that stock tetracycline; 18.3% within 10 Km of health facility that provides Trachomatous Trichiasis (TT) surgery and 18.6% were within 10Km of health facility that provides cataract surgery. Only 29.4% of the survey clusters were fully accessible by car. The majority of survey household head were farmers (70.8%) and illiterate (64.5%). About 48% of the households obtain their water from either a protected well/spring or piped distribution. Only 40.4% of the households reported that no animal is kept around the living quarter. Most households dispose garbage in open field (84.6%) and have no latrine (60.3%). Conclusion: The survey was conducted on a representative sample and provides reliable estimates at the national and regional levels. However, careful interpretations of results from remote and inaccessible areas are warranted. Access to eye care facilities are limited and need expansion in order to reduce the blindness and low vision load. Sanitation conditions favoring fly breeding are rampant and trachoma control program need to emphasize a more integrated approach.

An Appraisal of the Crisis in Darfur in Western Sudan and the Prospect for a Lasting Peace
MM Adamu
African Research Review , 2008,
Abstract: The Darfur crisis in western Sudan started in February 2003. It has to date claimed the lives of an estimated number of 200,000 people and another 2.5 million have been displaced and are now living in make shift refugee camps in Chad and neighbouring countries. All attempts to broker peace among the major warring factions had proved abortive and there is little or no hope that the displaced people would one day return to their villages. The killings, raping, suffering and starvation had continued despite the presence of the African Union troops which numbered about 7000 and deployed since 2004. A lot of propaganda, misinformation, fabrications and distortions have gone across to the public in trying to explain the causes and attendant consequence of the said conflict. These have clearly stood on the way to a real understanding of the genesis of the crisis for a lasting peace to be obtained and peace building to be accelerated, and end this bloodshed and suffering that had been the bane of the region for the past five years. This paper is an appraisal of the various views and opinions that had been put forward by different interest groups on the causes of the crisis, its impact and the way forward towards the attainment of peace.

The Legend of Queen Sheba, the Solomonic Dynasty and Ethiopian History: An Analysis
MM Adamu
African Research Review , 2009,
Abstract: The legend of Queen Sheba is undoubtedly one of the oldest legends, producing the oldest monarchy in Africa comparable, perhaps, only to the imperial dynasty in Japan or the Seifuwa dynasty in the Lake Chad basin. It is clearly one of the most accepted, believed, pervasive and resonant among all the legends of origin in Africa, today. The legend is still widely believed by the majority of Ethiopians and is reflected in their day to day daily lives. The existence of the Orthodox Tewahido church and other religious ceremonies, the presence of Beta Israel, the names of people like Makeda or Sheba and organizations such as the Sheba Miles are all testimonies to the legend living in the present Ethiopian communities. It purported to explain how the Ethiopian ruling dynasty ‘the Solomonic dynasty’ was descended from Solomon and through him from Abraham and the early patriarchs. The dynasty followed a succession of rulers from Yekunno- Amlak in circa 1270AD to the last emperor in the person of Haile- Selassie 1 who was deposed in 1974. This has lasted for a period close to a thousand years and making the dynasty to be one of the longest and oldest monarchies anywhere in the world. This paper is intended to look more closely at some of the claims made by this legend and its implication on the Ethiopian peoples, their heritage and identity. It is strongly argued that the legend is only legendary and a historical travesty. It cannot be proven historically. The paper concluded by examining the political as well as the socio-economic significance of the legend in contemporary discours.
The Somalian Crisis: A Legacy of Colonialism?
MM Adamu
African Research Review , 2009,
Abstract: The Somalian crisis seemed to have defied all solutions since its inception in1991. The country had become increasingly ungovernable and the condition had been described as the worst humanitarian crisis in the world. Somalia is considered by many to be a ‘failed state’ being the only state in the world with a vacant seat at the United Nations. It is not that it has been abolished but that it has entered what some analysts have called an undetermined ‘Gray Zone’. All these have been as a result of the crisis that engulfed the country since the fall of the regime of Siyyad Barre almost two decades ago and further complicated by the Ethiopian /American invasion of 2006. This paper examines the roots of the crisis, the attempts made at reconciliation as well as the role of international bodies in averting or escalating the crisis. The paper also looks at the possibility of finding a lasting peace in the country. It is argued that the Somalian crisis should be largely seen as a legacy of colonialism in the country as well as the misdeeds of some people like Siyyad Barre. The paper shows that the only way to peace is to allow the Somalians to determine the manner in which they want to be ruled.
Fourier Transform Infrared Spectroscopic Determination of Shale Minerals in Reservoir Rocks
MB Adamu
Nigerian Journal of Basic and Applied Sciences , 2010,
Abstract: Attenuated Total Reflectance Fourier transform infrared spectroscopy together with multivariate statistical regression was used to produce calibrations between spectra of standard mineral mixtures and gas shale reservoir rocks. A Classical Least Square (CLS) model was developed from the attenuated spectra of mixtures of five mineral standards chosen to represent the most frequently encountered minerals in shale-type reservoir rocks namely: quartz, illite/smectite (30:70), kaolinite, calcite and dolomite. The CLS model developed was able to quantify the mineral components of independent mixtures with an absolute error between 1 to 3wt% for all the pure minerals in the mixtures. Samples from a suite of shale reservoir rocks were analysed using standard Quantitative X-Ray Diffraction (QXRD) and with FTIR. Unknown mineral concentrations in the samples were then predicted using spectra and the calibration equations. Good correlations were achieved between the QXRD and ATR-CLS predicted concentrations (r2>0.8), with average absolute error of between 1 to 6wt%. This provides evidence that attenuated FTIR is a promising method for rapid and accurate determination of minerals in reservoir rocks for building higher resolution data without additional time consuming and expensive traditional analyses.
