Mothers/caregivers' knowledge of routine childhood immunization and vaccination status in children aged, 12-23 months in Ilorin, Nigeria.

Background: Immunization has averted millions of hospitalizations and deaths from vaccine-preventable diseases. It is a strong public health tool for childhood infection control and prevention. Many mothers are aware of routine immunization but with doubtable knowledge. Objectives: This study determined the mothers/caregivers' knowledge of routine childhood immunization and vaccination status of their children, aged 12-23 months in Ilorin East Area of Kwara State, Nigeria. It also identified some of the socio-demographic factors associated with good knowledge status of the mothers/caregivers. Methods: This was a community-based cross-sectional study, carried out between December, 2019 and January, 2020, among 456 mothers / caregivers-children's pairs. Subjects were recruited using multistage cluster sampling technique. Data were collected using a pretested, semi-structured, interviewer-administered questionnaire. Results: Up to 98.0% of the respondents were aware of childhood immunization with healthcare providers (92.1%) being their major source of information. Majority of the respondents (85.3%) had good knowledge of immunization, defined by a score ≤6 out of the 10 questions tested. There was a significant relationship between respondents' knowledge and full vaccination status of the children (p=0.001). The significant factors associated with good knowledge from binary logistic regression were mothers / caregivers' age >30 years, antenatal clinic attendance and at least secondary education (OR, p value = 10.60, 0.013; 8.50, <0.001; and 3.98, <0.001 respectively). Conclusion: Mothers / caregivers' knowledge on immunization was good and this positively affected the full vaccination status of their children. There is a need to sustain female education and encourage antenatal clinic attendance, as tools to improve childhood immunization.

Determinants of Exclusive Breastfeeding Practices Among Mothers of Infants Less Than Six Months Attending an Immunization Clinic in Southwestern Nigeria.

Background Despite being a cost-effective means of improving the childhood health indices, exclusive breastfeeding (EBF) remains low in the low middle-income countries. Hence, we evaluated the determinants of EBF among mothers of infants less than six months in Southwestern Nigeria. Methods This was a cross-sectional descriptive study that involved 271 mothers of infants aged less than six months attending the immunization clinic of the Bowen University Teaching Hospital, Ogbomoso, Nigeria. Pretested semi-structured questionnaires were used to get relevant information from the mothers who were recruited using convenience sampling method. Descriptive statistics was carried out while chi square test and binary logistic regression were used for inferential statistics. Results The mean age (±SD) of the respondents was 30.4 ± 5.0 years. The EBF rate in this study was 46.1% (125/271); 40.6% of mothers breastfed their infants within an hour of birth, with most (91.1%) breastfeeding their babies on demand. Factors associated with EBF included mothers' age > 30 years (OR 2.080, 95% CI 1.274-3.395). After controlling for potential confounders, family size > 4, (adjusted OR 2.053, 95% CI 1.120-3.762) and having vaginal delivery (adjusted OR 2.769, 95% CI 1.585-4.829) were the significant determinants of EBF practices among the study participants. Conclusion EBF practice was average in the studied population. Family size >4 and vaginal delivery were the determinants of EBF. There is a need to sustain the promotion of appropriate breastfeeding practices.

Haematological Profile of Children With Sickle Cell Anaemia in Steady State.

Introduction Sickle cell anaemia (SCA) is an inherited, autosomal recessive condition that results from a mutation in the ß-globin gene. Vascular occlusion is the underlying mechanism behind a myriad of complications encountered. This vascular occlusion is primarily caused by the increased tendency of red blood cells (RBC) to adhere to the vascular endothelium, and the activation of platelets and total leucocyte count (TLC), hence the need for a steady-state haematological profile in these patients. Method This was a cross-sectional study conducted over four months at a sickle cell clinic. Haemoglobin (Hb) concentration, haematocrit, platelet, TLC, mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH) and mean corpuscular haemoglobin concentration (MCHC) of the subjects were recorded and analysed. Results Ninety-nine subjects aged 1-18 years were recruited for the study. There were 53 (53.5%) males. Leucocytosis was seen in 80 (80.8%), anaemia in 99 (100%), and thrombocytosis in 30 (30.3%) patients. The mean Hb, TLC and platelets were 7.9 ± 1.3g/dl, 14.3 ± 4.5 x 103/mm3 and 391.5 ± 182.6 x 103/mm3 respectively. Mean MCV, MCH and MCHC were 81.3 ± 7.1 fl, 28.6 ± 2.9 pg and 35.2 ± 1.7 g/dl respectively. Children aged one to four years had the highest TLC (p=0.002) but the lowest mean Hb and platelet (p=0.094 and 0.06) respectively. The mean MCV, MCH and MCHC were lowest in children aged one to four years (p=0.047, 0.001 and 0.001). Conclusion Anaemia, leucocytosis and thrombocytosis are characteristics features of children with SCA, especially in male and younger subjects. Although Iron markers are generally normal in children with SCA, those under the age of five years tend to have lower values.

Acute Kidney Injuries in Children with Severe Malaria: A comparative study of diagnostic criteria based on serum cystatin C and creatinine levels.

OBJECTIVES: Serum creatinine levels are often used to diagnose acute kidney injury (AKI), but may not necessarily accurately reflect changes in glomerular filtration rate (GFR). This study aimed to compare the prevalence of AKI in children with severe malaria using diagnostic criteria based on creatinine values in contrast to cystatin C. METHODS: This prospective cross-sectional study was performed between June 2016 and May 2017 at the University of Ilorin Teaching Hospital, Ilorin, Nigeria. A total of 170 children aged 0.5-14 years old with severe malaria were included. Serum cystatin C levels were determined using a particle-enhanced immunoturbidmetric assay method, while creatinine levels were measured using the Jaffe reaction. Renal function assessed using cystatin C-derived estimated GFR (eGFR) was compared to that measured using three sets of criteria based on creatinine values including the Kidney Disease: Improved Global Outcomes (KDIGO) and World Health Organization (WHO) criteria as well as an absolute creatinine cut-off value of >1.5 mg/dL. RESULTS: Mean serum cystatin C and creatinine levels were 1.77 ± 1.37 mg/L and 1.23 ± 1.80 mg/dL, respectively (P = 0.002). According to the KDIGO, WHO and absolute creatinine criteria, the frequency of AKI was 32.4%, 7.6% and 16.5%, respectively. In contrast, the incidence of AKI based on cystatin C-derived eGFR was 51.8%. Overall, the rate of detection of AKI was significantly higher using cystatin C compared to the KDIGO, WHO and absolute creatinine criteria (P = 0.003, <0.001 and <0.001, respectively). CONCLUSION: Diagnostic criteria for AKI based on creatinine values may not indicate the actual burden of disease in children with severe malaria.

Prevalence and risk factors for hypertension among school children in Ilorin, Northcentral Nigeria.

BACKGROUND: The global prevalence of childhood hypertension has increased from 1% to 2% to 4%-5%, with a value as high as 9.8% reported in Nigeria. However, the various risk factors associated with childhood hypertension in Nigeria are less explored. The aim of this study was to determine the prevalence of hypertension and related risk factors (sociodemographic, family history of hypertension, history of snoring, birth order, and anthropometric indices) in primary school children in Nigeria. MATERIALS AND METHODS: A total of 1745 school children aged 6-12 years were selected using systematic random sampling method. Blood pressure (BP) was measured using the fourth report guideline. Those with BP higher than 90th percentile had repeated BP measurements on two more occasions (2 and 4 weeks after initial measurement). Relevant history was obtained, and anthropometric measurements were taken by the standard methods. Data were analyzed using SPSS version 20. RESULTS: Prevalence of systolic and or diastolic hypertension at the third visit was 3.0%. Prevalence of systolic hypertension (3rd visit) was more in females (3.3%) than males (1.3%), P = 0.004. Prevalence of diastolic hypertension (3rd visit) was higher in females (1.4%) than males (0.3%), P = 0.019. Hypertension showed no significant relationship with socioeconomic class, family history of hypertension, birth order, and history of snoring. Of the anthropometric indices (weight, height, body mass index (BMI), hip circumference, waist circumference, waist-to-hip ratio, and waist-to-height ratio, and only obesity (BMI ≥ 95th centile) was related with hypertension (odd ratio 8.3, 95% confidence interval 1.7, 40.3). CONCLUSIONS: Prevalence of hypertension is low (3.0%), and only obesity (BMI ≥ 95th centile) is associated with hypertension.

Iron-deficiency anemia with lithobezoar (pica): a rare cause of intestinal obstruction in a 5-year-old Nigerian child.

BACKGROUND: Despite a high prevalence of iron-deficiency anemia (IDA) in developing countries such as Nigeria, intestinal obstruction secondary to lithobezoar (an accumulation of ingested stones within the gastrointestinal tract) is uncommon. CASE PRESENTATION: Herein, we report a case of acute intestinal obstruction secondary to ingestion of large pebbles and IDA in a 5-year-old Nigerian boy. The patient was managed conservatively with the use of laxatives and a rectal wash-out, and the pebbles were excreted over 3 days. Oral iron therapy was also commenced with cessation of pica. DISCUSSION: Although the direction of causal relationship between pica and IDA remains debatable, routine screening for iron deficiency among children with lithobezoar is recommended. Besides managing complications associated with lithobezoar, such as intestinal obstruction, prompt initiation of iron therapy among those who present with features of iron deficiency may be beneficial.
