Echocardiographic reference z scores of right ventricular dimension and systolic function of children aged 5-12 years.

Background: Reference values for right ventricular dimension and systolic function in Nigerian children are scarce despite their high burden of right ventricular abnormalities. Reference values from other countries may not be suitable for use in Nigerian children because of possible racial variations in cardiac size.

Purpose: To develop reference values for right ventricular dimension and systolic function in healthy Nigerian children aged 5-12 years.

Rhythm abnormalities among hospitalised children in Lagos: a case series.

Arrhythmias refer to disturbances in heart rate or rhythm which leads to heart rates that are abnormally fast, slow or irregular. Rhythm abnormalities may be common among Nigerian children but there are only a few reports. The current write up is a clinical review of eight patients in various age groups including neonates, infants and older children.

Prevalence and determinants of peripheral arterial disease in children with nephrotic syndrome.

Peripheral arterial disease (PAD) is the least studied complication of nephrotic syndrome (NS). Risk factors which predispose children with NS to developing PAD include hyperlipidaemia, hypertension and prolonged use of steroids. The development of PAD significantly increases the morbidity and mortality associated with NS as such children are prone to sudden cardiac death.
