Haemangiopericytoma of the eyelid and orbit: report of 2 cases
MB Alhassan, F Kyari, A Mohammed
Nigerian Journal of Surgical Research , 2003,
Abstract: Haemangiopericytoma is a rare tumour of the pericytes. This is a report of two adult Nigerians presenting with large orbital masses confirmed at histology to be haemangiopericytoma of the eyelid and orbit respectively. Massive proptosis in both patients produced a clinical diagnostic dilemma, which was only resolved by histopathological studies. Key Words: Haemangiopericytoma, eyelid, orbit, tumour Nigerian Journal of Surgical Research Vol.5(1&2) 2003: 166-170

Jos Journal of Medicine , 2012,
Abstract: Aim: To determine the prevalence of presbyopia, refractive errors and usage of spectacles among Commercial Intercity Vehicle Drivers in Jos-Nigeria. Method: A descriptive cross-sectional survey of commercial intercity vehicle drivers at the Bauchi Road Motor Park, Jos, was undertaken in November 2006. The study instrument was a semi-structured questionnaire. Information obtained included demographic data, operational route, history of involvement in road traffic accident (RTA), cause of RTA and ocular history, type and usage of corrective spectacles if any. Each participant had a detailed ocular examination. Result: Up to 221 of 268 drivers were recruited (coverage: 82.5%). Their age ranged from 20-90 years (mean: 44.2 years, SD 9.2). 78 (35.3%) persons complained of difficulty in reading small prints while 17(7.7%) persons complained of poor distant vision. Ten (4.5%) drivers had a visual acuity of <6/12 and thus did not qualify to possess a driving licence. Presbyopia was the most common ocular diagnosis observed in 94(42.5%) persons. Most presbyopes 63 (67.0%) needed +1.50 to +2.00 DS correction. Only 10(10.6%) presbyopes had spectacles with presbyopic correction. Six (2.7%) persons had myopia while one person (0.5%) had unilateral aphakia. Conclusion: The prevalence of Presbyopia is high. Myopia is the most common refractive error. Usage of corrective spectacles is very low. There is an urgent need for enforcement of minimal visual standards for the purpose of certification and re-certification for drivers licence in Plateau State and Nigeria at large.
Total Lipid Profile, Faecal Cholesterol, very Low Density Lipoprotein Cholesterol (VLDL-C), Atherogenic Index (A.I) and Percent Atherosclerosis with Aqueous Fruit Extract of Solanum macrocarpum in Chronic Triton-Induced Hyperlipidemic Albino Rats

Current Research Journal of Biological Sciences , 2012,
Abstract: Studies were undertaken to investigate the effect of the aqueous fruit extract of Solanum macrocarpum on the total lipid profile [total cholesterol, triglyceride, high density lipoprotein-cholesterol (LDL-C) and low density liprotein cholesterol (LDL-C)], faecal cholesterol, very low density lipoproteincholesterol (VLDL-C), atherogenic index (A.I) and percent atherosclerosis on chronic titron-induced hyperlipidemic rats. The increase in HDL-C was dose-dependent and statistically significant (p<0.05) at both 24 and 72 h. There was no change (p>0.05) with increase in extract dose for both total cholesterol and triglycerides throughout the period of study while the decrease in LDL-C was significant (p<0.05) at 72h. The increase in faecal cholesterol with increase extract dose was significant (p<0.05) at 48 and 72h of study. The VLDL-C and percent atherosclerosis reduced with increase in extract dose. The decrease in VLDL-C was only significant (p<0.05) at 72h whilst that for percent atherosclerosis was significant (p<0.05) at both 48 and 72h. There was no change in A.I. (p>0.05). The results shows that the plant may be capable of reducing circulating lipids in chronic triton-induced hyperlipidemic rats probably by reducing absorption of lipids, thus, reducing hyperlipidemia. At the same time, the aqueous fruit extract probably has the potential to reduce the risk of development of heart diseases since VLDL-C has been shown to be beneficial and indicative of a lower risk of coronary heart diseases. Also, a reduction in percent atherosclerosis is desirable as this implies that atherosclerosis is reduced.

South African Medical Journal , 2011,
Abstract: Objective. To determine the prevalence and causes of visual loss in different ecological zones across Nigeria. Methods. A population-based survey using multi-stage, stratified, cluster random sampling with probability proportional to size comprising a nationally representative sample of adults aged ≥40 years from six ecological zones. Outcome measures. Distance vision was measured using reduced logMAR charts. Clinical examination included basic eye examination for all respondents and a detailed examination including visual fields, gonioscopy and fundus photography for those who were visually impaired or blind (i.e. presenting vision <20/40 in the better eye). A principal cause of visual loss was assigned to all respondents with presenting vision <20/40 in the better eye. Results. A total of 15 122 persons aged ≥40 years were enumerated, 13 599 (89.9%) of whom were examined. The prevalence of blindness varied according to ecological zone, being highest in the Sahel region (6.6%; 95% confidence interval (CI) 4.2 - 10.4) and lowest in the rain forest region (3.23%; 95% CI 2.6 - 3.9). Age/ gender-adjusted analyses showed that risk of blindness was highest in Sahel (odds ratio (OR) 3.4; 95% CI 2.1 - 5.8). More than 80% of blindness in all ecological regions was avoidable. Trachoma was a significant cause only in the Sudan savannah belt. The prevalence of all major blinding conditions was highest in the Sahel. Conclusions. The findings of this national survey may be applicable to other countries in West and Central Africa that share similar ecological zones. Onchocerciasis and trachoma are not major causes of blindness in Nigeria, possibly reflecting successful control efforts for both these neglected tropical diseases.
Extraction and characterization of seed oils
M.Z. Kyari
International Agrophysics , 2008,
Abstract: All the seeds examined in this project have been shown to contain varying levels of oils, mainly in the range of 26-42%, with the exception of Detarium microcarpum which contains about 7% of oils. Characterization of the oils by standard techniques suggest that they contain high levels of saturated fatly acids, judging by their low iodine values (IV) which did not exceed 88 in all cases. They are, hence, not suitable as alkyd resins for paint formulation but may, however, be used for soap production judging by their high saponification values (SV) in the range of 199-261. Lophira lanceolata showed considerable reduction in IV and increase in PV over a period of one month under storage conditions of light, darkness and refrigeration. In light, the IV value of 65 dropped by 50% at the end of one month, while under the same conditions the PV increased by almost tenfold. Less profound changes in both IV and PV were observed for oil stored in darkness and under refrigeration. The observed profound changes were explained as arising from oxidative rancidity of the oils. The nutritional non-oil residue of Lophira lanceolata may be suitable as animal feed judging by the balance of its nutrient composition.

Nigerian Journal of Clinical Practice , 2002,
Abstract: Objective: To determine the Pregnancy Complications and Outcome following Cervical Cerclage Operations. Subject: The case records of 76 patients who underwent Cervical Cerclage Operation for Cervical incompetent at the University of Maiduguri Teaching Hospital between January, 1983 and December 1999 inclusive were reviewed. In all the patients the diagnosis of Cervical incompetence was made based on the history of two or more midtrimester abortions or preterm deliveries and ultra-sound finding of internal OS diameter of 16mm or more in the second trimester of Pregnancy. Result: The MacDonald (81%) and shirodkar (19%) techniques were the two forms of Cerclage employed. Preterm rupture of membranes vulvovaginitis and Urinary tract infection were the Common Post-insertion Complications encountered while antepartum haemorrhage, Perineal/Cervical tear and mal-presentations were the common associated labour complications. 65.3% of the deliveries were term births while preterm deliveries made up 23.1% of the births. The overall foetal salvage rate was 85.3%. There was no maternal death. The Peritanal mortality was 84 per 1000. Conclusion: The overall foetal salvage rate of 88.3% observed in this study is high and in a developing Country like Nigeria with inadequate neonatal facilities and a slim foetal survival between 24-28 weeks, any procedure like cervical cerclage that will prolong pregnancy until foetal maturity is still relevant and beneficial. KEY WORDS: Cervical incompetence, Cervical Cerclage, Pregnancy outcome, Maiduguri, Nigeria. [Nig J Clinical Practice Vol.5(1) 2002: 25-28]
Pattern of requests for interspousal donation and transfusion in University of Maiduguri teaching hospital
SG Ahmed, O Kyari, AU Ibrahim
Nigerian Journal of Surgical Research , 2003,
Abstract: Background: The cases of 66 female patients who needed transfusion and requested for interspousal directed blood donations from their husbands at the UMTH Blood Bank from 1997 to 2001 were reviewed. The patients required blood for elective procedures, and wanted to be transfused with the blood of their husbands (interspousal transfusion) in order to avoid the risk of HIV infection, believing in the safety of their husband's blood but unaware of the remote immunological and clinical consequences of such transfusions, including haemolytic disease of the newborn in subsequent pregnancies. Method: The patients were assessed with respect to age, educational status and past history of transfusion with husbands' blood. The patients were appropriately counseled regarding the risks associated with such transfusions. Result: Out of the 66 patients studied, 51 (77%) were within the ages of 30-39 years while the remaining 15 (23%) patients were aged 20-29 years. Up to 58 (88%) of the patients had post secondary school education while the remaining 8 (12%) patients had secondary school education only. After counselling, 62 (94%) patients relinquished their earlier request for interspousal transfusions and opted for screened non-directed homologous donor blood while the remaining 4 (6%) patients opted for autologous donation. However, 3 (5%) patients had positive history of previous interspousal transfusion. Conclusion: Counseling efforts must be intensified against this apparently safe but undesirable and dangerous form of transfusion. (Nig J Surg Res 2003; 5: 23 – 26)
Global Renewable Energy Consumption and Oil and Gas Export: An Empirical Analysis of the Nigerian Economy
Bukar Zannawaziri,Adam Konto Kyari,Abdulsalam Masud
The International Journal of Applied Economics and Finance , 2012,
Abstract: Since after the Arab oil embargo of 1973, net oil importing countries developed the agenda for substituting fossil fuel and to date, renewable energy has become a major power source for most countries. This motivated for a study which analysed the possible impact of global renewable energy consumption on the Nigerian economy (Net Oil and Gas Export) over the period 1980-2008. The empirical results were obtained by analysing the data using the statistical time trend analyses (descriptive) in explaining the problem under investigation. The findings revealed that renewable consumption by Nigeria’s major oil and gas importers causes significant negative impact on its economy in terms of reduced crude oil and gas export. The result suggests that Nigeria as a mono-cultural economy should uncover alternative corridors other than oil and gas export to provide revenue in order to accelerate Nigeria’s economic growth and development.
