Microalbuminuria and hypertensive retinopathy among newly diagnosed nondiabetic hypertensive adult Nigerians

Objective: Microalbuminuria (MA) is a marker of vascular damage and has prognostic implications in hypertension. The objective of this study was to determine if the presence of MA increases the risk of hypertensive retinal damage in nondiabetic adult Nigerians with hypertension.Materials and Methods: A total of 96 consecutive newly diagnosed hypertensive patients attending the outpatient clinic and who consented and met the criteria for the study were recruited. There was also the same number of age- and sex-matched normotensive controls.Results: MA was present in 31 (32.3%) of the patients and 6 (6.3%) of the controls. The mean (±SD) ages of patients with and without MA were 52.5 ± 11.9 years and 48.3 ± 13.0 years, respectively. The diastolic blood pressure (P = 0.03) and mean arterial pressure (P = 0.01) were statistically higher in hypertensive patients with MA than in their counterparts without it. Patients with MA were more likely to have hypertensive retinopathy (HRP) than patients without it (71% vs 37%, P = 0.001). Advanced HRP, i.e., Grades III - IV, was more common in patients with MA than in those without it (22.6% vs 1.5%).Conclusion: This study shows a high prevalence of HRP in Nigerian hypertensives with MA

Factors affecting farmers’ participation in irrigation schemes of the lower Niger River Basin and rural development authority, Kwara State, Nigeria

In Nigeria the performances of many governments owned irrigation schemes have fallen short of expectation. Management issues and steps required to ensure sustainable growth in irrigated agriculture were not given proper attention. This study therefore examined those factors affecting farmers’ participation in irrigated agriculture at the Lower Niger River Basin Development Authority (LNRBDA) in Kwara State, Nigeria. One hundred and sixty (160) respondents were selected from communities around LNRBDA site at Oke Oyi for this study through a two-stage sampling procedures. Data collected were analyzed using descriptive statistics and logistic regression model. The result showed that majority of respondents were farmers within the economic active age and relatively literate. They identified factors affecting farmers’ participation in the scheme to include poor knowledge of irrigation techniques(78.3%), Insufficient water for irrigation during the dry season (80.5%), high cost of labour (75.8%), Lack of access to credit facility (76.6%), poor response to farmers’ needs by the Authority (85.2%), Irregular pumping of water (86.7),. Consequently, the study recommended encouragement of participatory irrigation scheme (PIM) in which farmers would take charge of daily allocation of water while the authority serves as supervisory body and stepping up of extension activities within the surrounding villages.Keywords: Irrigation, Water, Participatory Irrigation Management, LNRBD

Clinico-pathological pattern of nasopharyngeal carcinoma in Ilorin, Nigeria

Nasopharyngeal carcinoma is an uncommon tumour in Nigeria but the burden of the disease in terms of morbidity and mortality is very high.The aim of the study was to document the clinic-pathological characteristics of nasopharyngeal carcinoma in Ilorin, North central Nigeria.This was a retrospective review of all patients seen in ENT department, University of Ilorin Teaching Hospital with the diagnosis of nasopharyngeal carcinoma between January 1st 1999 and December 31st,2008. The patient's biodata, clinical presentation and histopathological findings are presented. The histopathological diagnosis was in accordance with the 1991WHOclassification. A total of 30 patients with histologically confirmed nasopharyngeal carcinoma seen during the study period accounted for 2% of the total cancers recorded in Ilorin cancer registry. There were 20 males and 10 females with a mean age of 48.7 ± 15.9 years. The commonest presenting complaint was cervical lymphadenopathy in 96.7% of patients followed by epistaxis (66.7%) and hearing loss (66.7%). Identifiable riskfactors included regular intake of ungutted salted smoked fish (76.7%) and tobacco use (23.3%) with some having both risk factors. Histologically, undifferentiated carcinoma was the commonest (70%) followed by welldifferentiated keratinizing squamous cell carcinoma (20%) and differentiated nonkeratinizing squamous cell carcinoma (10%).Undifferentiated carcinoma was the commonest type of nasopharyngeal carcinoma reported from this study especially among males in the 4th and 5th decades of life. Identifiable risk factors included consumption of ungutted salted smoked fish with tobaccon usage. Early diagnosis with effective referral system and easy access to radiotherapy would improve the survival outcome in patients with the disease

Uncommon complications of Otitis media in a tertiary center: A Case Series

Background: The aim is to report cases of unusual and infrequent complication of otitis media in North-central Nigeria, as well as evaluate their outcome. We present 7 case reports of patients with unusual complications from otitis media in our setting.Case 1: A fifteen year old Yoruba girl presented at the Accident and emergency of our hospital with a 2 week history of left sided ear ache, 10 day history of left sided ear discharge and 3 day history of jaw and neck stiffness. There was a positive history of use of ‘Turari’ locally prepared perfume and application of an ear drop from a local chemist. Caregiver said patient was fully immunized. Examination revealed a young girl, conscious and alert, not pale, anicteric with stiff neck, positive and rigid joints on movement.Case 2: An 8 year old Yoruba girl presented first to the eye clinic with 2 days history of swelling of the right eye, associated pain, reduction in vision and eyelid swelling without eye discharge or itch. There was a of purulent ear discharge 8 days prior to eye symptoms. No history of trauma was obtained. Examination revealed proptosis with zygomatic abscess extending to the post-auricular. She had incision and drainage with systemic and topical antibiotics for ear dressing. Outcome was uneventful.Conclusion: The unusual complication of otitis media still occurs in our environment usually due to late presentation and contamination of wound. Prevention is still the best option.  Keywords: Otitis Media, Complications, Otogenic Tetanus, Ophthalmic, Proptosi

Diabetic foot care: Self reported knowledge and practice among patients attending three tertiary hospital in Nigeria

Background: Diabetes Mellitus (DM) foot complications are a leading cause of mortality in developing countries and the prevalence of diabetes is expected to increase in the next decades in these countries. Theaim of this study was to determine the knowledge and practice of foot care among diabetes patients attending three tertiary hospitals in Nigeria.Methods: This is a cross-sectional study carried out from November 2009 to April 2010. Pre-tested structured questionnaires were administered by medical officers to diabetes patients. The outcome variables were knowledge and practice regarding foot care. The knowledge and practice scores were classified as good if score .70%, satisfactory if score was 50-69% and poor if score was < 50%.Results: Of 352 diabetes patients, 30.1% had good knowledge and 10.2 % had good practice of DM foot care. Majority (78.4%) of patients with poor practice had poor knowledge of foot care. With regard toknowledge, 68.8% were unaware of the first thing to do when they found redness/bleeding between their toes and 61.4% were unaware of the importance of inspecting the inside of the footwear for objects. Poor footpractices include; 89.2% not receiving advice when they bought footwear and 88.6% failing to get appropriate size footwear. Illiteracy and low socioeconomic status were significantly associated with poor knowledge and practice of foot care.Conclusion: This study has highlighted the gaps in the knowledge and practice of foot care in DM patients and underscores the need for an educational programme to reduce of diabetic foot complication

Performance of traditionally-managed Bunaji (White Fulani) cattle under smallholder dairy production systems in Oyo State, South-West, Nigeria

The remarkable reduction in tsetse fly and its vector trypanosomosis in the South-West zone of Nigeria have led to the development of smallholder dairy production which is predominantly practised by the Fulani agropastoralists in the zone. This study was conducted by the administration of structured questionnaires to farmers in the Derived savannah area of Oyo State in the South-West zone of Nigeria with aim of assessing the performance of traditionally managed Bunaji (White Fulani) cattle in this newly encroached zone by the Fulani pastoralists from the northern parts of the country. The survey showed that milk offtake or partial milk yield (0.6 kg/day), pregnancy rate (53.2%), calving rate (49.5%), calf crop (37.11%) and body condition score (4.3) were low and typical of tropical breeds of cattle. Also, average age at first calving (47.8 months) and calving interval (18.1 months) were on the high side. Majority (80%) of the dams produced their young ones during the wet season while a few ones (20%) calved during the dry season. Diarrhoea (84%), helminthosis (72%) and sand eating (64%) were the major diseases of calves in wet and dry season, respectively; whereas in addition to diarrhoea and sand eating, low milk production (90%) was peculiar to adult cattle in dry season. Calves’ overall mortality was 24.11% with majority (73.77%) occurring during the first week of life; it was higher in wet season (86.89%) compared to the dry season (13.11%). Overall mortality for adult cattle was 5.83% with the mortality, in contrast to the calves’ mortality, being higher in dry season (69.39%) than in wet season (30.61%), and the females (91.84%) more susceptible than the males (8.16%). The results indicate that the performance of traditionally-managed cattle in smallholder dairy production systems in Oyo State, South-West, Nigeria is poor and below their genetic potentials due to poor management.Keywords: Major diseases, mortality, milk offtake, reproductive performance, seaso
