We described a case of necrolytic migratory erythema without glucagonoma in a 33-year-old man. The patient had been heroin-dependent, HIV negative since the age of 23. He had no medical history of note and all the investigations revealed normal parameters. This is the first case of necrolytic migratory erythema without glucagonoma associated with heroin abuse.
Diurnal variation of plasma aldosterone and cortisol concentration in man was studied in 13 anephric subjects and 7 normal subjects. All subjects were ambulatory and active throughout the study except during an 8-hour sleep period. Six anephric subjects received Kayexalate (sodium polystyrene sulfonate) during the studies to prevent potassium accumulation and increase in plasma potassium concentration. Diurnal variation of plasma aldosterone concentration with peak and nadir concentrations at 12:00 noon and 12:00 midnight respectively was demonstrated in the studies on normal subjects. Changes in plasma aldosterone concentration were not significantly correlated with changes in plasma concentration but were highly correlated with changes in PRA (P less than 0.001). There was a highly significant correlation between plasma aldosterone and potassium concentration in the anephric subjects studied without Kayexalate administration (P less than 0.001). In the anephric subjects who received Kayexalate, plasma aldosterone and potassium concentration remained stable, and no correlation could be demonstrated. No diurnal variation of plasma aldosterone concentration could be demonstrated in either group of anephric subjects, whereas plasma cortisol concentration varied as in the studies on normal subjects. Conclusion. Diurnal variation of plasma aldosterone concentration is dependent on continued stimulation by the renin-angiotensin system. Loss of this stimulation has no demonstrable effect on the diurnal variation of plasma cortisol concentration.
We analyzed the cutaneous reactions to systemic analgesic-antipyretics and nonsteroidal anti-inflammatory drugs reported to the spontaneous reporting system of the Gruppo Italiano Studi Epidemiologici in Dermatologia (GISED). The system has been active since 1988, with periodic intensive surveillance exercises, and 202 dermatologists have collaborated. Up to December 1991, 2,137 reactions had been collected, of which 713 were reactions to systemic analgesic-antipyretics and nonsteroidal anti-inflammatory drugs. A general profile of the reactions was identifiable. It included, in order of frequency, urticaria/angioedema, fixed eruptions, exanthemas, erythema multiforme and Stevens Johnson syndrome. Fixed eruptions and Stevens Johnson syndrome were reported with exceedingly high frequency in association with feprazone. Our system also revealed previously unreported reactions, including fixed eruption to nimesulide, fixed eruption to piroxicam and fixed eruption to flurbiprofen.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
