We have explored the baroreceptor reflex on nineteen patients free of all cardiovascular diseases having contracted acute primary polyradiculitis. The tilt test (at 30 degrees from the horizontal line) demonstrates that, at the acute point of the disease, there is a dysregulation of the arterial pressure characterised by an orthostatic hypotension with a lack of normal increase of the peripheric arterial resistances. Once the motor activity restituted, this dysregulation disappears without sequelae. The clinical and pharmacological tests prove a failure in the baroreceptor arc and shows that sympathetic and parasympathetic pathways to the heart and vessels are functionally normal. Thus, this study localizes the defect on the afferent pathways conducting the local information perceived on the baroreceptors.

[Disseminated intravascular coagulation with microangiopathic hemolytic anemia and bone necrosis associated with a prostatic microcarcinoma].

Presentation of a case of disseminated intravascular coagulation with micro-angiopathic hemolytic anemia, associated with a micro-carcinoma of the prostate. In the absence of other etiology it is postulated that the carcinoma was responsible for the hematological disturbance in spite of its small size andlack of either metastases or mucin secretion. The unusual discovery in this disease of bony necroses of the vertebrae, which are attributed to ischemia following micro-thromboses, is also discussed.
