Electrical power lines and childhood leukemia: a study from Greece.

Residential proximity to electrical power lines of different voltage in relation to childhood leukemia was investigated through a case-control study undertaken in Greece during 1993-1994. The study comprised 117 incident cases of childhood leukemia and 202 age-, gender- and place-of-residence-matched controls. Four measures of exposure to magnetic fields were developed, using data provided by the Public Power Corporation of Greece: Voltage (V) divided by the distance (d), V/d2, V/d3 and an adaptation of the Wertheimer-Leeper code.

Hypersensitivity reactions during hemodialysis related to the use of acetate dialysate. A case report.

A patient developed a hypersensitivity reaction two weeks after being put on hemodialysis with acetate dialysate. The reactions appeared exclusively during hemodialysis and were relieved immediately after its termination. These allergic manifestations disappeared with substitution of bicarbonate for acetate dialysate and reappeared upon rechallenge with acetate dialysate.
