Local hyperthermia cleared multifarious viral warts in a patient with Cushing's syndrome.

A female Cushing's syndrome patient had been suffering from extensive viral warts for months. She was diagnosed with flat warts, common warts and plantar warts. The plantar warts on her right foot were initially treated using local hyperthermia at 44°C for 30 min according to a defined protocol, followed by treatment targeting a common wart on her left thumb. In response to hyperthermia, the flat warts on her eyelid dissipated within 12 weeks, and when combined with a 1 week administration of imiquimod, the common warts and plantar warts completely disappeared within 8 weeks. There were no signs of recurrence and during this treatment her Cushing's syndrome was alleviated. This pioneer trial suggests that local hyperthermia may serve as an effective mean for treating multiple cutaneous warts under the conditions of a systemic immuno-compromised disease.

Kinetic spectrophotometric determination of rutin by its inhibitory effect on the oxidation of amaranth by potassium periodate.

A novel kinetic spectrophotometric method is described for the determination of rutin. The method is based on the inhibitory effect of rutin on the oxidation reaction of amaranth by potassium periodate in acidic media at 100 degrees C. The linear range for the determination of rutin is 0.02 - 0.50 microg/ml, and the detection limit is 0.014 microg/ml. The method has been successfully applied to the determination of rutin in medicine of rutin tablet and traditional Chinese medicine.
