RESUMO
Meningitis caused by Listeria monocytogenes is a rare affection: it develops from close contagion as professional illness (veterinarians, butchers) or in newborns by infected mothers; in indirect way for ingestion of contaminated food in subjects at high risk: elderly, immunosuppressed patients, alcoholics, diabetics. Clinically it is not diversified from the other bacterial meningitises. In this paper we present a case of Listeria monocytogenes meningitis in an adult female, without a sure occasion of infection and in absence of the factors of typical risk.

After a careful review of the literature on physiopathological role of the renin-angiotensin-aldosterone system in cases of arterial hypertension with hypokalaemia, a simple diagnostic procedure is suggested to differentiate between this and secondary hypertensions which, though few, are often curable. Three clinical cases examined in the medical department of Casalpusterlengo Hospital are presented in which the study of the renin-angiotensin system proved decisive for a correct diagnosis of the hypertension.
