Brain stem glioma presenting as gastro - oesophageal reflux

Patients with chronic renal failure treated by dialysis must often restrict their fluid intake. Children find this restriction one of the most difficult aspects of treatment by dialysis, particularly if dialysis was preceded by a phase of polyuria. As a result many children experience episodes of fluid overload, which may have fatal consequences. Fluid removal by dialysis may be slow to begin and we have found that oral administration of 20% mannitol is effective for the rapid removal of body water through the gastrointestinal tract.
