Impact of pre-hydration duration on high-dose methotrexate induced nephrotoxicity in childhood acute lymphoblastic leukaemia in resource constraint centers: a randomized crossover study.

Purpose: Hydration before starting high-dose methotrexate (HD-MTX) ensures good renal perfusion and alkaline urinary pH. The duration of pre-hydration is not uniform across protocols. We compared 6-h versus 12-h of pre-hydration for HD-MTX therapy in childhood acute lymphoblastic leukaemia (ALL) at our centre where serial MTX level monitoring is not feasible.

Hypereosinophilia: a rare cause of stroke and multiorgan dysfunction.

Eosinophilia can occur due to a plethora of allergic, infective, neoplastic and idiopathic conditions. Hypereosinophilic syndrome (HES) is characterised by sustained eosinophilia and multiorgan dysfunction in the absence of an identifiable cause. It may range from a self-limiting condition to a rapidly progressive life-threatening disorder, of which ischaemic stroke is a rare presentation.
