RESUMO
A 21-year-young man had an episode of myalgia and chilling 3 days prior to hospital admission. He had consumed common doses of acetaminophen for one day, and was presented in the sauna room for an hour. On the next morning, he complained of dyspnea and was admitted. He presented in rhabdo-myolysis and acute renal failure with increased up-take in the proximal muscles by (99m)Tc-MPD bone scan. He was treated by hemodialysis and discharged on the twenty-eighth hospital day. Rhabdomyolysis has the variable causes. The causes of this case are two, the first cause is common doses of acetaminophen. But, there is no reports for rhabdomyolysis by common doses of acetaminophen only. However, we should consider that acetaminophen is a contributing factor in this case. The second cause is viral infection. Our patient had myalgia and chilling prior to hospital admission. Heat- stroke is well known cause of rhabdomyolysis. The mechnisms for rhabdomyolysis in this disease are hypovolemia, total body potassium deficit, and increased variable cytokines. Sauna, the last cause of our rhabdomyolysis case may have the same mechanisms with heatstroke. Our case had two causative factors, common doses of acetaminophen and sauna. These factors might be cooperated in our case of rhabdomyolysis and acute renal failure.
