Photodynamic therapy is a new therapeutic technique that utilizes a photosensitizer selectively localized in tumors and activated by exposure to laser light, resulting in tumor necrosis. Photodynamic therapy has proved to be effective in the treatment of early cancers of the lung, esophagus, stomach, and uterine cervix, and was approved by the Japanese goverment. We consider early oral cancers to be good candidates for photodynamic therapy. This report describes two cases of tongue carcinoma treated by photodynamic therapy.

Abstract: Cresol is commonly used in homes and hospitals as a disinfectant. In dentistry, formocresol (FC) is often used for infectious root canal therapy. Too much cresol ingestion causes severe systemic failure. An autopsy of fatal cresol poisoning is described.Case report: A 23-year-old Japanese female was admitted to ICU of Tohoku University Medical Hospital with a history that she had taken up to 100 ml of cresol soap solution 4 hours earlier. On arrival, she was semiconscious with cresol breathodor, 32.5°C body temperature and 75/50 mmHg blood pressure. Gastric lavage was not performed because of severe esophageal edema. She died after blood plasma transfusion, hemodialysis and blood filtering performed for about 60 hours. Post-mortem examination demonstrated 1) digestive tract failure: necrotizing inflammation of oro-pharynx, larynx, esophagus and stomach, 2) respiratory tract failure: sputum in trachea and bronchi, edema and hemorrhage of lung, 3) hepatic failure: severe centrolobular necrosis, 4) renal failure: tubular degeneration and 5) hemorrhagic diathesis.
