ABSTRACT
Background: The prevalence of Attention Deficit Hyperactivity Disorder (ADHD) or its risk in North Central Nigeria has not been adequately reported. The consequences of missing the disorder and its co-morbidities are usually costly to the society. Method: Using a multi-stage sampling technique, nine primary schools from where a total of 1,480 pupils were selected across the three local government areas within Ilorin metropolis (two public and one private school from each LGA) we selected. An ADHD assessment tool - the short version of Conner's Teacher Rating Scale was administered on the pupils through their respective class teachers after training the teachers on how to administer the tool. They were classified into Inattention ADHD and Hyperactive/impulsive ADHD. Results: Of the 1480 (741 males and 739 female) pupils recruited, public schools contributed 1033 (69.8%) pupils while 447(30.2%) were from the private schools. A prevalence of 15.8% was found for ADHD risk. Statistically significant differences were present in the male to the female distribution of the Inattention ADHD, Hyperactivity ADHD (each with p< 0.05) but not in the overall ADHD index(p> 0.05). The ADHD Index was higher in the public schools. Conclusion: Prevalence of primary pupils aged 6-12 years in Ilorin at risk of ADHD is 15.8%, no significant gender variation was found. It is hereby recommended that Pre-primary school entry screening for ADHD should be instituted considered to enhance early recognition and prompt intervention so as to save the country from bad childhood that develops into bad adulthood with its myriads of anti-social and behavioural consequences

Background: The need to identify the intellectual capability of neurologically impaired children dictates their educability which can be estimated through their intelligence quotient (IQ). Draw-a-man test for IQ estimation is available, easy and has been validated in Nigeria. Method: Through a prospective, cross-sectional study that lasted 12 months (January-December, 2011), children aged 4 years and above attending neurology clinic were recruited once they have no severe motor or sensory limitations affecting their upper limbs and can obey the instruction to draw a person. Anthropometry was carried out on them and they were comfortably seated to draw a person. The parents or caregivers were instructed not to make any suggestion or hint to them and no time limit was given. Their drawings were assessed using the 52 parameters of Ziler and interpreted accordingly. Ethical procedures were adhered to. The analysis was done using SPSS version 16 and an interactive calculation tool for chi-square tests of goodness of fit and independence. Results: Seventy-five (45 male, 30 female) children met the inclusion criteria. Their clinical conditions were Epilepsy 48 (64%), Cerebral Palsy 6 (8%), ADHD 5 (6.7%), Down Syndrome 4 (5.3%), Speech/Hearing impairment 3 (4.0%), Hypothyroidism 2 (2.7%) and 7 (9.3%) others. Their ages ranged from 4 years to 16 years (mean±SD = 9.7± 3.8 years). Their IQ distribution were Normal 4 (5.3%), Borderline 12 (16.0%), Mild Mental Retardation 16 (21.3%), Moderate Mental Retardation 19 (25.3%), Severe and Profound Mental Retardation 24 (32.0%) with no significant difference in relation to their birth order. Conclusions: Ninety-six per cent of the study population had IQ below normal. Epilepsy was the commonest condition seen in the Paediatric Neurology clinic and all categories of IQ are seen among children with epilepsy

Objective: The study was carried out to document the pattern of childhood malignant tumors which were diagnosed at the University of Ilorin Teaching Hospital, Ilorin, and compare with previous reports from other parts of Nigeria and elsewhere and also highlight the challenges and strategies for effective management of these diseases in our environment. Methods: A ten year retrospective analysis of all cancers diagnosed in children below the age of 18 years at the study centre between January 2000 and December 2009 was carried out. Case folders of all children diagnosed with malignant tumors within the study period were retrieved from the Cancer Registry Department of the Hospital and were analyzed with respect to age, gender, morphological or histological type of malignancy, extent of disease, treatment modality, and survival outcome. Results: Ninety nine (99) children were diagnosed with various malignancies during the study period. Sixty seven (67; 67.7%) were boys and 32 (32.3%) were girls giving a male to female ratio of 2:1. There were 22 cases (22.2%) recorded in children aged below 4 years and 72 cases (72.7%) were diagnosed in children between 4 -14 years. Lymphomas were the most prevalent malignancies encountered accounting for 54 cases (54.5%), Burkitt’s lymphoma constituted 43 (79.6%) of all lymphoma cases. The distribution of the five foremost malignancies recorded were as follows: Burkitt’s lymphoma (43 cases), Nephroblastoma (10 cases), Retinoblastoma (8 cases), Non Hodgkin’s lymphoma (7 cases) and Acute leukaemias (5 cases). Other malignancies included Osteogenic sarcoma (5), Hodgkin’s lymphoma (4), and 2 cases each of primary liver cell carcinoma, neuroblastoma, rhabdomyosarcoma and nasopharyngeal tumor. Conclusion: The distribution of the various childhood malignant tumors recorded in this study is similar to the pattern reported in previous studies from Nigeria and other countries. However, there appears to be a lower prevalence of leukemia recorded in this study compared to the earlier findings. The challenges which were identified in the diagnosis, management and overall outcome of our patients included limited number of diagnostic tools, late presentation in the hospital, high patient default rate, poverty, and shortage of chemotherapeutic drugs.
