[Emphysematous pyelonephritis: 3 cases].

We report 3 patients who developed emphysematous pyelonephritis. All were diabetic females over 50 years of age with unilateral necrotizing pyelonephritis. Intra and perirenal gas was demonstrated and all patients had infection by E coli.

[Enalapril in essential arterial hypertension].

The hypotensive effect of enalapril, a converting enzyme inhibitor, given as a single agent once daily, was evaluated prospectively over a 16 week period in 20 subjects. One patient abandoned therapy and 2 were withdrawn (increased creatinine levels in one and the need for associated therapy in the other). Side effects developed in 3 patients: creatinine elevation, skin rush and a "salty taste", respectively.
