The Authors report a case of Lyell's syndrome. Previous administration of sulfadossine was identified as the precipitating cause of the syndrome. The clinical history and the treatment of the case are described. Two aspects of the latter were considered to be particularly important: a careful control of the hydroelectrolytic balance and positive action to favour the rapid re-epithelialization of the cutaneous area affected.

A study on the contamination of antiseptics was done in a teaching hospital, during March and April 1989. Ninety-five samples of 9 antiseptics from 23 wards were cultured. Results showed that 2 of 12 and 3 of 5 samples of mercurochrome and chlorhexidine-cetrimide compound were contaminated. This led to a wider scale study on the two products. It was found that over one-half of the samples of mercurochrome and 6 of 54 samples of chlorhexidine-etrimide compound were contaminated. Mercurochrome was contaminated by gram-positive and chlorhexidine-cetrimide compound by gram-negative bacteria. Contamination of mercurochrome was found in samples taken from the pharmacy and wards, and of chlorhexidine-cetrimide compound from wards only. Mercurochrome was removed from the hospital formulary and the use of chlorhexidine-cetrimide compound was more restricted.
Two new methods were recently introduced for the determination and quantification of egg viability in Schistosoma haematobium infections by staining eggs filtered from urine on Nytrel filters with mercurochrome and iodine. Both methods showed reasonable agreement with the best currently available method, centrifugation hatching, but it appeared that improved agreement could be obtained by modifications of timing and technique. The present paper describes the standardization of staining times and microscopic counting techniques; the modifications made gave substantially improved agreement with the reference method and achieved the most important objective, not to have zero estimates of viability when the centrifugation method detected hatching.
Mercurascan (MSC), a mercury derivative of fluorescein, was studied as to its effect on the survival of allogeneic kidney grafts in dogs. A single perfusion of the donor's kidney with saline solution with MSC added in a ratio of 1 mg/100 ml was found to have significantly extended the graft survival time from 10.8 days (SE +/- 0.6) to 15.4 days (SE +/- 1.6). Graft survival time extension proved to be even more significant after a single dose of MSC given to the donor (0.5 mg/kg b.w.) and repeated administration of an equal MSC dose to the recipient twice weekly. Listed are detailed morphological changes in tissue specimens from the kidney, lymph nodes, spleen, and many other organs of a dog surviving for 42 days. A very moderate rejection lesion with merely tiny lymphocytic infiltrates was proved in the kidney. Lymph node structure was almost entirely obliterated with lymphoid tissue extinction. There was loss of white pulp in the spleen. The absence of morphological changes in the other organs suggested good tolerance of the preparation. More studies are called for to elucidate the complex MSC intervention in the process of rejection.
Since the end of 1974 we have used Betaisodona instead of Mercurochrome for Grob's three stage tanning because the harmful effects of the mercury contained in the Mercurochrome could not be excluded with certainty. The results were compared in 80 patients in each case. The two groups were comparable with regard to age, degree and extent of the burns. We obtained an equally firm and rapidly drying scab using Betaisodone as with Mercurochrome. Complete loosening of the scab took 16 days with Betaisodona and 14 days with Mercurochrome. Wound infection was no more frequent than with Mercurochrome disinfection.
