Residual Effect of Organic Wastes on Productivity of an Ultisol in Abakaliki, South Eastern Nigeria (Published)
An experiment was carried out to study residual effect of organic wastes amendment on productivity of an ultisol.The field was laid out in a Randomized Complete Block Design with four treatments of 20 t ha-1 equivalent to 8kg/plot of burnt rice mill waste (BRMW), unburnt rice mill waste (URMW), sawdust (SD) and control which were replicated five times to give a total of twenty experimental units. The treatments were applied in 2006 and 2007 cropping seasons and residual effect studied in the third season. A hybrid of maize (Oba super II hybrid) variety was used as a test crop. Data obtained were subjected to analysis of variance (ANOVA) while means were separated with Fisher’s Least Significant Difference. The results showed that the textural class remained sandy loam. Hydraulic conductivity of organic wastes amended soil was significantly (P<0.05) higher when compared to control. While bulk density of SD amended plot was 7% lower, total porosity and hydraulic conductivity in same treatment were higher by 16 and 6% when compared to control, respectively. Total porosity, hydraulic conductivity. Available phosphorus and CEC of organic wastes amended soil were significantly (P<0.05) higher than control. Grain yield of maize was higher in BRHD, URHD and SD amended plots by 5, 9 and 13% respectively than control. Residual effect of organic wastes improved the productivity of ultisol more than control, and thus, could be recommended for sustainable soil productivity in Abakaliki agroecological farming system.
The Prognosis of Acute Stroke in a Tertiary Health Centre in South-East Nigeria (Review Completed - Accepted)
Background and purpose: Stroke is a common neurologic disorder and it is the third leading cause of mortality worldwide after ischaemic heart disease and cancer. The purpose of this study was to determine the prognosis of acute stroke in Federal Teaching Hospital Abakaliki (FETHA) South-East Nigeria.
Methods: It was a retrospective, descriptive and hospital based study conducted in a tertiary health centre in Abakaliki south-east Nigeria. The stroke register of the neurology unit was reviewed and relevant data were extracted and analyzed.
Results: Stroke accounted for 12% of medical death with 24hour, 7day and 30day mortality rate of 5%, 10% and 15% respectively. Factors associated with mortality include advanced age, female sex, extremes of blood pressure, loss of consciousness and haemorrhagic stroke.
Conclusions: Stroke accounted for significant proportion of medical deaths and its mortality was highest within the first 24hrs post ictus though lower than most hospital based studies. There should be regular health education with emphasis on primary prevention. Also, stroke patients should be referred early to a stroke unit for adequate management
Pattern of Neurological admissions in the tropics: Experience at Abakaliki South-Eastern Nigeria (Review Completed - Accepted)
Background: The pattern of neurological admissions varies amongst different regions of the world and this depends on many factors including the regional burden of neurological disorders.
Objective: To study the pattern of neurological admissions in a tertiary health centre in Abakaliki South Eastern Nigeria and to compare it with that from other parts of the country.
Methods: A review of admissions into the medical wards of the Federal Teaching Hospital Abakaliki south-eastern Nigeria from July 2012 to June 2013 was done using the register of admissions and discharges.
Results: Out of 1247 patients admitted in medical ward over the study period, 267 (21%) had neurological disorders with mean age of 55.1±20.2years. There were 154(58%) males and 113(42%) females, with a sex ratio of 4:3. Seventy two percent of the patients were between 30 and 69years. Stroke accounted for 62% (166) of the neurologic admissions. Others were central nervous system (CNS) infections, seizure disorders, hypertensive encephalopathy, myelopathies, CNS tumors and neurodegenerative disorders in descending order of frequency.
Conclusion: The burden of neurological disorders is high with male preponderance in Abakaliki south-eastern Nigeria mainly of the productive population. Stroke and CNS infections were the most prevalent neurological disorders identified which are both largely preventable. There should be good health planning that will address the enormous neurological disease burden and emphasize preventive health.
