Metformin induced severe hypophosphatemia in a patient on hemodialysis.

A 67-year-old diabetic and hypertensive woman presented to us with very low serum phosphate levels (PO₄⁻ =1.1 mg/dL) about 40 days after initiation of hemodialysis (HD). The phosphate binders were discontinued, because they were thought to be the cause of hypophosphatemia.

The red blood cell deformability in patients suffering from end stage renal failure on hemodialysis or continuous ambulatory peritoneal dialysis.

Anemia is the main problem for patients suffering from end stage renal disease (ESRD). This study aimed to determine whether the index of rigidity (IR), that shows red blood cells (RBCs) deformability and the possible IR disturbances can provide an explanation about the cause of anemia, in patients undergoing maintenance hemodialysis (HD) or on peritoneal dialysis. The IR was determined in 39 hemodialyzed patients, who were already in dialysis for a period of time ranging from 16 to 120 months (mean+/-SD=41.

The effect of intense passive apnea in the acid-base balance and electrolytes.

The aim of this study was to investigate the disturbances of the acid-base balance and electrolyte disorders in healthy individuals in the greatest passive apnea (prior to apnea and prior to first inhalation). The changes of the acid-base balance, the serum potassium and calcium levels as well as the disturbances of the cardiac rhythm were studied in a group of 15 healthy males aged 18 to 41 years old. Seven individuals part of the original group participated in a second trial.
