[A few reflections of a clinician on the language of the somatic symptoms].

This paper presents a series of reflections upon the clinician's activity. His duty begins by having to understand what the words uttered by the patient mean and by assigning a clinical value to somatic symptoms. While the former of these tasks means that the patient must be followed in his particular way of self-diagnosis of his somatic perceptions and in his particular way of inventing his physical reality, the latter is rather easier and it's based on the use of a preformed model of the localization, intensity, duration, sequence and normal interpretation of the symptoms.

[Thoughts concerning the realms of arterial blood pressure].

Several realms of arterial blood pressure are analyzed. 1. The realm of physiological regulation of arterial blood pressure is discussed from the point of view of an intelligent design.

[The renin saga].

This saga is the story of a scientific development. From the search of a mechanism to explain high blood pressure, research was orientated to the functions of an omnipresent biochemical system. And from the search to elucidate the etiology of arterial hypertension, research has ended up studying the local, functional and structural activity of the renin-angiotensin system and the possibilities of interfering with its actions.

[Atheroembolism].

The observation of the eye-ground allows the recognition of atheromatous emboli within the arterial lumen and some of the characteristics of the evolution of such an accident. An analogy is drawn with pathological observations and clinical findings. The increased use of arterial invasive diagnostic and therapeutic procedures has increased the chances of producing atheroembolism giving the opportunity of observing its pathological and clinical consequences.
