In-hospital psychoeducation for family caregivers of Nigerian children with cancer (The RESCUE Study).

OBJECTIVES: High levels of caregiver burden (CB) are experienced by informal caregivers of pediatric patients with cancer. There is increasing evidence highlighting the extent of CB across sub-Saharan African countries, although there remains lack of interventions that target improvements in their experience. This study aimed to determine the impact of a structured psychoeducation program on caregivers' outcomes relating to preparedness to provide care, burden of caregiving, and quality of life (QoL). METHODS: This quasi-experimental (pre-and-posttest) design, involved family caregivers of children on admission for cancer treatment in 4 Nigerian tertiary hospitals. Eligible participants received 2 structured, psychoeducational training sessions delivered by a multidisciplinary oncology team, focusing on the management of patients' condition, spiritual care, self-care, and support. RESULTS: Subjects were mainly female (79.5%) and mostly mothers to children undergoing cancer treatment (74.7%). Commonest cancer type was acute lymphoblastic leukemia (23.9%) with evidence of metastatic disease found in 9.6% of children. Significant improvements were observed between pre- and posttest for unmet needs (z = -9.3; p < 0.001), preparedness for caregiving in palliative care (PCPC) (z = -7.0; p < 0.001), and overall QoL (z = -7.3; p < 0.001). A significant reduction in CB was also reported (z = -8.7; p < 0.001). SIGNIFICANCE OF RESULTS: This psychoeducational intervention (PEI) resulted in significant improvements in unmet needs, CB and significant improvements in PCPC. However, a reduction in QoL of the family caregivers was also observed. Findings from this study should encourage the use of well-crafted PEIs, delivered within hospital settings to promote improvements in outcomes for informal caregivers of hospitalized children suffering from cancer, in an African context. Further intervention development is required to better understand intervention components influencing changes in outcomes, while exploring feasibility testing and adaptation to similar settings in Nigeria and within Africa.

Assessment of depression in children and adolescents with sickle cell anemia in a low-resource setting: a comparative study.

Children with sickle cell anemia (SCA) usually face psychological complications especially depression. Assessment of depression in resource-limited settings may help identify the extent to which the children with SCA in such settings may need its introduction as part of routine care. This study aimed to assess depression in children and adolescents with SCA in a low-resource setting. This cross-sectional observational study involved 84 children and adolescents with SCA aged 7-17 years who were selected using a systematic random sampling technique. Their controls were 84 age- and sex-matched individuals with AA hemoglobin genotype. A structured questionnaire was used to collect socio-demographic data while depression was assessed with the Children's Depression Inventory. The prevalence of depression was non-significantly higher in subjects compared to the controls (8.3% vs. 2.4%) (Fisher's χ2 = 1.88, p = 0.171). Though not statistically significant, the subjects had 3.7 times higher odds of having depression compared to the controls (OR = 3.7; 95% CI 0.75-18.50; p = 0.107). Of the 5 depression subscales, the subjects had a significantly higher difference in the negative mood (p = 0.042). Despite the comparable prevalence of depression with their normal controls, children and adolescents with SCA had a higher negative mood and higher odds of having depression than normal individuals. Thus, there is a need for the introduction of depression assessment as a complement to routine care of these children with SCA in resource-poor settings.

Sexual and procreation preferences of adolescents and young adults infected perinatally with HIV in Southeast Nigeria: a hospital-based cross-sectional study.

INTRODUCTION: children with perinatal human immunodeficiency virus (HIV) infection now survive to adolescence and adulthood and so are confronted with issues related to sexuality and sexual reproductive health. This study is aimed at determining the sexual knowledge and behaviours of these adolescents, determining their procreation intention and the impact of their age, gender and understanding of the mother to child transmission risk on their procreation intention. METHODS: a hospital-based cross-sectional study of adolescents and young adults aged 15-24 years infected with HIV in the perinatal period, accessing tertiary care in Enugu. A pretested questionnaire was used to obtain information about socio-demographic variables, sexual knowledge and behaviour, procreation intention and knowledge of prevention of mother-to-child transmission of HIV. Data analysis was descriptive and a test association using fisher´s chi square was done on the variables. RESULTS: seventy-one adolescents were studied. The majority (95.8%) were less than 20 years of age. Mean age was 17.01 ± 1.80 years with M: F ratio of 1:1.7. Nineteen (26.8%) were sexually active with 15 (78.9%) having single partners. About 80% had their first sexual activities before the age of 18 years. Fifty-six (78.9%) received some form of sex education. Only gender and socio-economic status was significantly related to marriage and procreation intentions of respondents. CONCLUSION: there´s need for sustained/intensive education programs and policy on sexual practices with focus on perinatally infected adolescents who may not be well informed on risk and consequences of their sexual preferences.

Sexual maturation of HIV-infected and uninfected male children in Abakaliki, South-East, Nigeria: a cross-sectional study.

Introduction: HIV infection, through various mechanisms causes a derangement in sexual maturation. This study compared the Marshal and Tanner staging of HIV-infected and uninfected males. The aim of the study was to determine the sexual maturation in male children infected with HIV on HAART in Abakaliki. Methods: this was a cross-sectional and comparative study involving 80 HIV-infected boys aged 8-17 years and 80 uninfected counterparts matched for age and socio-economic class. Stages of sexual maturation (testicular size and pubic hair) were determined according to the method proposed by Marshall and Tanner. The testicular size was measured using an orchidometer. Data analysis was done with SPSS version 20. Structured questionnaire was used to collect information on socio-demographics. Results: assessment of pubic hair development, showed that 45 (56.2%) of the subjects were in the pre-pubertal stage compared to 27 (33.8%) among the controls, this relationship was statistically significant (p=0.005, OR = 2.5, C.I=1.3-4.8). The mean testicular volume among subjects was found to be 8.29 ± 8.26mls compared to 11.57 ± 8.26mls found in controls. This relationship was also statistically significant. There were significant statistical relationships between duration on HAART and clinical stages of disease with both pubic hair development and testicular volume of subjects and controls. Conclusion: HIV-infected males had significantly delayed onset and progression of sexual maturation. Routine assessment of the sexual maturation of HIV-infected children as well as addressing the modifiable variables influencing sexual maturity is recommended.

Folate levels in children with sickle cell anaemia on folic acid supplementation in steady state and crises at a tertiary hospital in Enugu, Nigeria: a prospective, comparative study.

Introduction: Folic acid supplementation is an integral aspect of the management of children with sickle cell anaemia (SCA) especially in Africa. In spite of this, there have been concerns about lower folate levels, especially during crisis. Aim: To determine red cell folate levels of children with sickle cell anaemia in steady state and during crisis and compare with those with haemoglobin AA genotype. Method: This study was prospective, hospital based, and comparative. Fifty children with sickle cell anaemia were recruited during crises and followed up until they met the criteria for attaining steady state. The controls were fifty children matched with those with SCA for age and gender and had haemoglobin AA genotype. Red cell folate estimation was done with the Electrochemiluminescence Immunoassay (ECLIA) method using the automated Roche Cobas e411 equipment. Results: The median (IQR) red cell folate level in children during sickle cell crisis was 265.95 (134.50) ng/ml, which was significantly lower than the median (IQR) of 376.30 (206.85) ng/ml obtained during steady state. Most children with SCA (41 out of 50) had significantly higher folate levels during steady state (T=1081, Z-score= -4.660, p < 0.001). Median level of red cell folate was lower during anaemic crisis compared to vaso-occlusive crisis, though not significantly so (N(50), U = 214.00, Z-score= -1.077, p = 0.305). The median red cell folate level of normal controls was 343.55 (92.90) ng/ml, which was significantly lower than the 376.30 (206.85) ng/ml obtained during steady state (N(50), U= 209.00, Z-score= -7.177, p <0.001). Conclusion: Median red cell folate levels of the study participants were within normal limits, though most children with SCA had significantly higher levels during steady state compared to crisis. Normal controls had significantly lower red cell folate levels than the children with SCA during steady state.

Clinical depression in children and adolescents with sickle cell anaemia: influencing factors in a resource-limited setting.

BACKGROUND: Sickle cell anaemia (SCA) is the commonest monogenic haematologic disorder resulting from the inheritance of homozygous mutant haemoglobin genes from both parents. Some factors have been identified as important in explaining the variability in depression in sickle cell anaemia (SCA). Information on this is limited in a resource-limited setting like Nigeria. This study aims to determine factors which influence depression in children and adolescents with sickle cell anaemia in a resource-limited setting. METHODS: Systematic random sampling technique was used in this cross-sectional study to select children and adolescents aged 7-17 years at the weekly sickle cell clinic of the University of Nigeria Teaching hospital (UNTH) Enugu, Nigeria. Pretested, structured questionnaire was used to collect sociodemographic and disease severity data while depression was assessed using the Children's Depression Inventory. RESULTS: Age and educational level had significant positive linear relationships with depression (r = 0.253, p = 0.02; r = 0.225, p = 0.04 respectively) while gender (χ2 = 0.531, p = 0.466), socioeconomic status (χ2 = 0.451, p = 0.798) and disease severity (χ2 = 0.422, p = 0.810) had no relationship with depression in children and adolescents with SCA. CONCLUSION: Depression in children and adolescents with SCA increased with increasing age and educational level. Psychological evaluation should be integrated into routine assessment of children with SCA during their follow up visits as they get older and progress in class.

Relationship between disease severity and folate status of children with sickle cell anaemia in Enugu, South East Nigeria.

BACKGROUND: Repeated crises in children with sickle cell anaemia (SCA), which is a manifestation of disease severity, results in depletion of their minimal tissue folate stores, with higher likelihood of folate deficiency. The study aimed to determine the relationship between disease severity and the folate status of children with SCA attending University of Nigeria Teaching Hospital (UNTH), Enugu. METHODS: This was a hospital based, cross-sectional study conducted between September 2018 and March 2019. One hundred participants were recruited, consisting of 50 children having sickle cell crisis and 50 age and gender matched haemoglobin AA genotype controls. Relevant information was documented using a pretested questionnaire. Sickle cell severity score was determined using frequency of crisis, admissions and transfusions in the preceding one year, degree of liver and splenic enlargement, life-time cummulative frequency of specific complications of SCA, leucocyte count and haematocrit. RESULTS: Folate deficiency was observed in eight percent of the subjects and none of the controls. The difference was not significant (Fisher's exact = 4.167, p=0.117). The odds of being folate deficient was 8.5 times more likely during anaemic crisis than in vaso-occlusive crisis, though not significant (95% C.I 0.05 - 89.750, p = 0.075). The mean SCA severity score was 8.06 ± 3.64, signifying a moderate SCA severity in the study population. There was a no relationship between folate status and severity of SCA (Fisher's exact = 0.054, p = 0.949). CONCLUSION: Folate status in children with SCA is not affected by their disease severity. Therefore, there may be no need for additional folate supplementation with increasing severity of sickle cell anaemia.

The effect of sickle cell anemia on the linear growth of Nigerian children.

OBJECTIVES: Despite the high prevalence of children with sickle cell anaemia (SCA) in West Africa, there is paucity of data on the height velocity and prevalence of growth failure in SCA patients. With advances in clinical care of SCA patients, could there be a spatial and secular trend in the growth pattern of these children? Hence, the compelling needs to embark on this study. The objectives of the study were to determine the prevalence of growth failure among patients with SCA and its correlation with age, gender and age at diagnosis. METHODS: A Prospective longitudinal study of a cohort of sickle cell anaemic paediatric patients from Pediatrics SCA Clinic, University of Nigeria Teaching Hospital, Ituku Ozalla. Patients were enrolled over a period of two years using a non-parametric convenient sampling method. Their heights were measured at baseline, three months, six months and at 12 months intervals and subsequently plotted on a standard WHO growth chart. The height velocities at different monthly intervals were calculated and compared with the WHO standard normal linear growth rates) for children (used as control) to identify those with GF. (i.e. <10th percentile). The main outcome measures were the mean height velocities at different months' intervals calculated and compared using the repeated measurement analysis of variance (ANOVA) and the Wilcoxon signed test. RESULTS: A cohort of 316 children aged 1-18 years with SCA was evaluated with a male preponderance of 161 (57.4%). The mean age and age at diagnosis were 11.04 ± 5.56 and 4.2 ± 1.7 years, respectively. The prevalence of growth failure and short stature was 84.7%. The burden of GF was highest among post-pubertal participants (94.1%). The most important predictor of growth velocity deficit was age (R2=0.045, standard ß coefficient = -0.22, t=-03.51, p=0.001). CONCLUSIONS: The study demonstrated high prevalence of growth failure in children and adolescents with SCA which intensified with advancement in age and older age at diagnosis.

Glanzmann's thrombasthenia: a rare bleeding disorder in a Nigerian girl.

INTRODUCTION: Glanzmann's Thrombasthenia (GT) is a rare autosomal recessive bleeding disorder due to defective platelet membrane glycoprotein GP IIb/IIIa (integrin αIIbß3). The prevalence is estimated at 1:1,000,000 and it is commonly seen in areas where consanguinity is high. CASE PRESENTATION: The authors report a 12 year old Nigerian girl of Igbo ethnic group, born of non-consanguineous parents, who presented with prolonged heavy menstrual bleeding which started at menarche 3 months earlier, weakness and dizziness. She had a past history of recurrent episodes of prolonged epistaxis, gastrointestinal bleeding and gum bleeding during early childhood. On examination, she was severely pale with a haemic murmur and vaginal bleeding. The initial diagnosis was menorrhagia secondary to bleeding diathesis possibly von Willebrand's Disease. She was on supportive treatment with fresh whole blood, fresh frozen plasma and platelets until diagnosis of GT was made in the USA. Currently, she is on 3 monthly intramuscular Depo-provera with remarkable improvement. CONCLUSION: To the best of our knowledge, this is the first documented report of GT in our environment where consanguinity is rarely practised. Our health facilities require adequate diagnostic and treatment facilities for rare diseases like GT.

Persistent hematuria among children with sickle cell anemia in steady state

ABSTRACT Introduction: Persistent hematuria is a chronic complication of sickle cell anemia (SCA) which can progress to chronic kidney disease. The practice of early detection of persistent hematuria in children with SCA in steady state is important for timely intervention. Objective: To determine the prevalence of persistent hematuria among children with sickle cell anemia in steady state and compare the result with that of a group of HbAA controls. The outcome will possibly strengthen the health policy on the need for regular screening for persistent hematuria in children with SCA. Methods: Children with sickle cell anemia, aged 2-18 years in steady state, were recruited consecutively from the sickle cell clinic at the University of Nigeria teaching Hospital Enugu. The controls were similarly recruited from the children's outpatient clinic. To determine persistent hematuria, dipstick urinalysis and microscopy were performed for both subjects and controls at enrollment and repeated after four weeks. Results: Out of the 122 children with SCA studied, 5 (4.1%) had persistent hematuria. None (0%) of the 122 age- and gender-matched HbAA controls had persistent hematuria. This difference in prevalence of persistence between HbSS patients and HbAA controls was statistically significant (p= 0.02). Conclusion: Persistent hematuria still occurs significantly more among children with SCA, even among those in steady state. Routine urinalysis at follow-up visits in children with SCA is strongly recommended, as this will aid early detection and prompt management to prevent progression to chronic kidney disease.

Knowledge and awareness of individual sickle cell genotype among adolescents in a unity school in Southeast, Nigeria: a cross-sectional study.

OBJECTIVE: Our study sought to assesses the knowledge and awareness of individual sickle cell genotype among adolescents. METHODS: Participants were recruited from a large school in Southeast Nigeria where adult prevalence of sickle cell trait is 25%. Data was collected through a 50-item survey with previously pretested questions that assessed awareness of individual genotype, general knowledge of sickle cell disease, perception of sickle cell trait and sickle cell anaemia (SCA). Additionally, self-reported genotype was compared to the school's admission records to determine accuracy of self-reported genotype. The knowledge scores were summed on a binary basis with one point assigned for a correct answer while zero was given for an incorrect response. RESULTS: Four hundred and nine (409) students were approached and enrolled in the study. A vast majority (94%) of the respondents reported being aware of their genotype and two-thirds had the awareness during school admission. However, in specific knowledge of sickle cell, majority (89.7%) of the participants miscalculated the probability of having a child with SCA in married carrier couple and 71.9% misidentified the proportion of Nigerians with sickle cell trait. Assessing level of knowledge of sickle cell, only very few of the adolescents (7.3%) were found with the expected high knowledge scores of 7-8. CONCLUSION: Although a significant proportion of respondents were aware of their genotype, most were unaware of the implications of sickle cell trait and thought that people with sickle cell trait also have symptoms of sickle cell disease. Also, only a few of the respondents have the expected level of sickle cell knowledge. A focused educational intervention among this age group is crucial as they embark on making reproductive health decisions.

Pre-Transition Readiness in Adolescents and Young Adults with Four Chronic Medical Conditions in South East Nigeria - An African Perspective to Adolescent Transition.

INTRODUCTION: When a child reaches a certain age, he or she moves over to the adult physician. For this to maximally benefit the child, there has to be a process of equipping the child with skills required for taking on more responsibilities. Transitioning involves a process in which the adolescent with chronic illness is prepared ahead of time to enable them to eventually transfer to adult care with good outcomes. In high-income countries with well-organized health financing, the transitioning process begins as early as 12 years. In Africa, this process is not as organized and most hospitals would write a referral letter once the child turns 18 and transfer to adult clinic. In four of our chronic disease clinics (asthma, HIV, sickle cell anaemia and chronic kidney diseases) patients up to 24 years old are still attending the paediatric clinics. Understanding transition readiness among African adolescents remains a gap. Our findings will form a basis for informed practices for adolescent clinics in African countries. METHODS: This was a descriptive cross-sectional study of pre-transition readiness in adolescents and young adults with chronic illnesses attending four outpatient specialist clinics in a tertiary hospital in Enugu Nigeria. This was done using the validated STARx Questionnaire. Total scores were computed and scores nearer the upper limit of 90 were acceptable, while mean subdomain scores of 4 and above were considered as optimal level of transition readiness. Demographic and clinical data were also collected. Acceptability to move on to adult-oriented care was documented using binary response (yes/no). Cross tabulations were done, and likelihood ratios obtained for predictors of acceptability of transition. Significant value was set at p-value of ≤0.05. RESULTS: A total of 142 adolescents and young adults aged 12 to 24 years were studied. There were 38.0% (54), 24.6% (35), 22.5% (32) and 14.8% (21) from HIV, sickle cell anaemia, asthma and nephrology clinics, respectively. Their mean age was 15.6 years ± 2.4, and 48.6% (69) were male. The mean total transition readiness score was 56±14 and this was not nearer the higher spectrum of total scores obtainable. Highest mean scores (3.7) occurred in the knowledge subdomain while least mean score (2) was noted in the use of medication reminders. The males had highest scores in the knowledge subdomain while the females were better informed about medication adherence and were more inquisitive about their chronic illness. Only about 37% (53) of the adolescents and young adults welcomed the idea of moving on to adult-care clinics. Children who had less frequent emergency hospital visits and better treatment outcome accepted the idea of transfer to adult care. Irrespective of the age all participants had suboptimal subdomain scores. High scores did not influence the participants' choice to embrace transfer to adult care. CONCLUSION: There is suboptimal transition readiness irrespective of the age. The older age groups were less willing to transfer to adult care. Better disease knowledge and better communication skills did not positively influence acceptability of transfer to adult care.

Generalized lymphadenopathy: an unusual presentation of burkitt lymphoma in a Nigerian child: a case report.

INTRODUCTION: Burkitt Lymphoma is the fastest growing tumor in human and the commonest of the childhood malignancies. Generalized lymphadenopathy is a common feature of immunodeficiency associated Burkitt lymphoma but an uncommon presentation of the endemic type in Human Immunodeficiency Virus (HIV) negative children. CASE PRESENTATION: The authors report a 6 year old HIV negative boy who presented with generalized lymphadenopathy, cough, weight loss, fever and drenching night sweat and had received native medication as well as treatment in private hospitals. His examination revealed hepatosplenomegaly, bull neck with generalized significant massive lymphadenopathy. Diagnosis was missed initially until a lymphnode biopsy for histology confirmed Burkitt lymphoma. He was managed on combination chemotherapy with complete resolution and now on follow up. CONCLUSION: To the best of our knowledge, this is the first documented report of its kind of endemic Burkitt lymphoma involving lymphnodes generally as the primary site. High index of suspicion and early biopsy are the key in this uncommon presentation.

Impact of zinc on sexual maturation of female sickle cell anemia (SCA) children in Enugu, Southeast Nigeria.

Adolescence is an important developmental period of childhood. Good health and adequate nutrition consisting major food constituents and trace elements like zinc are fundamental for optimal sexual maturation. To determine the relationship between zinc levels and pattern of breast and pubic hair development, as well as menarcheal age of female SCA children aged 6-18 years and their matched controls with hemoglobin genotype AA. Cross sectional, case-control study. Information on biodata, age at menarche, medical and drug history as well as 24-hour dietary recall was documented using interviewer administered questionnaire. Sexual maturation was assessed using Tanner staging and zinc levels determined using Atomic absorption spectrophotometer. Eighty-one subjects were compared with 81 controls. There was significant delay in the mean age of attainment of various Tanner stages of breast and pubic hair in the subjects. Mean age of 14.81 ± 1.07 years at menarche in subjects was significantly higher than 12.62 ± 1.18 years in controls (p = 0.001). Serum zinc of 58.01 ± 10.58 µg/dl in subjects was significantly lower than 68.37 ± 8.67 µg/dl in controls (p = 0.001). Serum zinc levels were found to have a significant positive relationship with stages of sexual maturation and mean age at menarche. Reduced serum zinc in children with SCA was associated with delayed sexual maturation.

A Multi-centre Survey of Acceptability of Newborn Screening for Sickle Cell Disease in Nigeria.

Background Sickle cell disease (SCD) is a major genetic disease that manifests early in life and may lead to significant morbidities. One of the health care services that have been effective in reducing the burden of SCD in developed countries is newborn screening (NBS) followed by pneumococcal vaccines, penicillin prophylaxis, and hydroxyurea treatment. Yet, in sub-Saharan African countries, where about 75% of annual affected babies worldwide are born, NBS programmes are largely unavailable. It is not clear whether this is due to technical challenges associated with setting up such programmes, or significant cultural and social barriers to its acceptance in such settings. Objective Our aim was to ascertain the attitudes to and acceptability of NBS in Nigeria among various socio-demographic groups including health professionals, undergraduate students, parents of children with SCD and SCD patients. Methods Data on socio-demographic characteristics, knowledge of SCD and attitude towards NBS were collected using a semi-structured pre-tested questionnaire from April to July 2014 across 15 health institutions and university campuses in Nigeria. Data were collected from 1,301 respondents across Nigeria. Results There was good knowledge of SCD as an inherited blood disorder. Although 86% of respondents (n = 1,119) supported NBS, there was a statistically significant relationship between support for NBS and age (p = 003), educational status (p = 000) and religion (p = 000). Conclusion This study suggests that there is a good acceptability of NBS across Nigeria. The main barriers to its use are likely to be financial and practical, rather than social or cultural.

Comparison of Tanner staging of HIV-infected and uninfected girls at the University of Nigeria Teaching Hospital, Ituku/Ozalla, Enugu, Nigeria.

BACKGROUND: A number of factors influence sexual maturation in adolescents, including chronic illnesses like HIV. Marshall and Tanner devised a method of classifying the adolescent based on the level of sexual maturation into five stages. This study compared the Tanner staging of HIV-infected and uninfected girls. METHODS: This was a cross-sectional study of 100 HIV-infected girls aged 8-18 years and 100 uninfected counterparts matched for age and social class. Using standard photographs as a guide, stages of sexual maturation were determined according to the method proposed by Marshall and Tanner. Data analysis was done with SPSS version 20. p-values <0.05 were regarded as significant. RESULTS: The study participants were aged 8-17 years. Fifty-five subjects compared to 39 controls were still in pre-pubertal breast developmental stages while 45 subjects (45%) compared to 61 controls (61%) have commenced breast development (p=0.024). Similarly, 52 subjects compared to 31 controls were in the pre-pubertal pubic hair developmental stages, while 48 subjects (48%) compared to 69 controls (69%) had commenced pubic hair development (p=0.003). CONCLUSIONS: Perinatal HIV infection affected the onset of pubic hair and breast development but did not significantly affect the attainment of sexual maturation.

Preliminary Evaluation of a Point-of-Care Testing Device (SickleSCAN™) in Screening for Sickle Cell Disease.

Sickle cell disease affects about 150,000 births annually in Nigeria. Early diagnosis is hampered by factors such as centralized and urban localization of laboratories, high cost of diagnostic equipment and inadequate skilled manpower to operate them. The need for a low-cost, portable, easy-to-use diagnostic test for sickle cell disease is critical, especially in resource-poor countries. In this study, we evaluated the performance characteristics of a novel point-of-care testing device (SickleSCAN™), and its acceptability and feasibility, as a possible screening tool for sickle cell disease. In the first phase, we assessed the performance characteristics of SickleSCAN™ by evaluating 57 subjects comprising both children and adults attending a primary health center, for Hb SS (ßS/ßS; HBB: c.20A>T), Hb SC (ßS/ßC; HBB: c.19G>A) and Hb AS (ßA/ßS) using SickleSCAN™, cellulose acetate electrophoresis (CAE) and high performance liquid chromatography (HPLC). Performance characteristics such as diagnostic sensitivity and specificity were compared to HPLC as a standard method. We subsequently undertook a second phase wherein the acceptability and feasibility of the device for sickle cell disease screening, was evaluated using semi-structured and structured questionnaires among 197 healthcare personnel and 221 subjects, respectively. Sickle cell disease was carried by 3.4% of the subjects. The diagnostic sensitivity, specificity and test efficiency of SickleSCAN™ for sickle cell disease (Hb SS and Hb SC), were 100.0, 98.2 and 98.2%, respectively. Findings from this study showed SickleSCAN™ to be a viable screening tool that can easily be applied in community-based screening for early diagnosis of sickle cell disease with little expertise and low cost.

Neurocognitive Function of School-aged HIV-infected Children in Enugu, Nigeria.

BACKGROUND: Evidence has shown neurocognitive problems often exist among human immunodeficiency virus (HIV)-infected children. There are limited data for children in Nigeria. METHODS: This was a cross-sectional study of 100 school-aged perinatally HIV-infected children seen in the paediatric HIV clinic and age/sex-matched controls from the general paediatric clinic. Neuro-cognitive functioning was assessed using the Raven's progressive matrices (RPM) that has been adapted for the Nigerian population. RESULTS: The mean RPM score of subjects was 22.97 ± 11.35 compared with 32.93 ± 15.71 among controls (p < 0.001). Twenty-two percent of subjects in the HIV-infected group vs. 56% of controls were in the above-average intelligence group on the RPM. Thirty-four percent had average scores, while 22% were in the below-average scoring range.
