Child, hypertension and oral health.

Hypertension is a major public health issue in industrialized nations. Many efforts have focused on the primary prevention and control of hypertension in adults. Nevertheless, the increasing incidence of hypertension in younger age groups has drawn attention to the severity and complications of the disease in children and adolescents. Public health implications of hypertension in children are overwhelming because many of these individuals will eventually face medical squeal into adulthood. Reproducibility of blood pressure in children can be challenging, especially in younger individuals, and the practitioner should be alert for shallow reading ranges in young children. Safe provision of dental care to hypertensive children requires knowledge about the aetiology of the elevation in blood pressure, oral manifestations, target organ damage, and possible drug interactions. This article provides an overview of hypertensive children and their oral health management. The recommendations presented in this article have been formulated using the available data regarding hypertension in children.

Remediation of lead from lead electroplating industrial effluent using sago waste.

Heavy metals are known toxicants, which inflict acute disorders to the living beings. Electroplating industries pose great threat to the environment through heavy load of metals in the wastewater discharged on land and water sources. In the present study, sago processing waste, which is both a waste and a pollutant, was used to adsorb lead ions from lead electroplating industrial effluent. Two types of sago wastes, namely, coarse sago waste and fine sago waste were used to study their adsorption capacity with the batch adsorption and Freundlich adsorption isotherm. The parameters that were considered for batch adsorption were pH (4, 5 and 6), time of contact (1, 2 and 3 hrs), temperature (30, 37 and 45 degrees C) and dosage of the adsorbent (2,4 and 6 g/L). The optimal condition for the effective removal of lead was found to be pH 5, time of contact 3 hrs, temperature 30 degrees C and dosage 4 g/L with coarse sago waste than fine sago waste.
