Treatment of disseminated malignant melanoma with cisplatin in combination with whole-body hyperthermia and doxorubicin.

Twenty-three patients with disseminated malignant melanoma were entered in a pilot study conducted from January 1983 to January 1988. There were 14 men and nine women. Fifteen patients were available for final evaluation. The criterion for evaluation was the completion of the two thermochemotherapy cycles. Patients received multiple-drug chemotherapy consisting of cisplatin (80 mg/m2, i.v., day 1) and doxorubicin (50 mg/m2, i.v., day 2); applications were repeated on days 22-29. Cisplatin was administered concurrently with whole-body hyperthermia (WBH) on day 1 (body core temperature 41 +/- 0.5 degrees C/h). The following response rates were achieved: complete remission (CR) 0/15; partial remission (PR) 3/15; minor response (MR) 4/15, no change (NC) 3/15; progressive disease (PD) 5/15. These findings are within the range known from the literature of the response to multiple-drug chemotherapy without hyperthermia. Toxicity, in particular renal toxicity, was not enhanced by the combined application of cisplatin and hyperthermia, with the exception of the bone marrow toxicity, which seemed to be slightly more pronounced than that known from normothermic application. Concurrent administration of thermochemotherapy with cisplatin and WBH (41 +/- 0.5 degrees C/h) is no more effective than the multiple-drug chemotherapy without hyperthermia as reported in the literature.

Hair removal in 40 hirsute women with an intense laser-like light source.

Until recently, previously applied methods to remove hair have ultimately proven ineffective or resulted in the formation of scars and small wounds. Different methods for removing hair in a more or less permanent way have been used: electrolysis, thermolysis and the blend method. In this study we describe the removal of hair without side-effects by means of non-laser incoherent emitted light, produced by the ILS flashlamp. In a multicenter study we treated 40 women with a median age of 38.6 years with hirsute hair growth of different hair colours on the upper lip and chin. In general 76.7% of the hair was removed within 6 treatments, with an average fluence of 38.7 J/cm2 and a mean wavelength of 585 nm per patient. A correlation was found between the percentage reduction of hairs and the number of treatments and between hair removal and needle epilation before treatment. Furthermore, a correlation was seen between hair reduction and wavelengths of 570 nm and 550 nm. No association was found between hair removal and clinical data of the patients, nor between hair reduction and technical data of the device. This study presents a new alternative for hair removal.
