[Evaluation of an educational program on calcium and phosphorus metabolism for patients on hemodialysis].

This cohort study evaluated the effects of an educational program about metabolism and control of serum levels of calcium (Ca), phosphorus (PO4), parathormone (PTH), Ca x PO4 product on 33 stable patients on hemodialysis. Patients were randomized into two groups: control (n = 17) and intervention (n = 16). The control group received information on vascular access.

Thyrotoxic hypokalemic periodic paralysis: a life-threatening syndrome.

Hypokalemic periodic paralysis is a rare life-threatening syndrome, potentially reversible when detected at an early stage. Hypokalemia may also occur in other conditions characterized by muscle weakness. Acute myopathy associated with thyrotoxicosis has been described in Asian populations, although it seldom affects Caucasians or African-Americans.
