[Informed consent].

The informed consent, in which the physician informs about procedures to be performed and requests approval, puts into practice the communication between physicians and patients. The consent will always be verbal and will only put writing in complex or risky situations. This doctrine, that promotes the recognition of patients autonomy, is employed since the end of World War II. Its main features are mental competence to know and elect, adequate and comprehensible information and voluntary acceptance or denial. In the situations of requested paternalism, therapeutic privilege and placebo use, information is not given and the consent is not requested. In all research protocols, a written informed consent must be requested. The consent is a form of communication that tries to defend patients rights as something close and alive, and should not become a ritual.

[In the search of a language for medical ethics].

After World War II, the interest in medical ethics increased and several international codes defending patients rights appeared. Four pragmatic, non ideological and non religious principles were defined to analyze clinical ethical problems. Autonomy, the capacity of self management and to reach our own informed decisions; the informed consent is the way to accomplish this principle. Beneficence, the basic principle of medical acts, with the risk of being transformed in an extreme paternalism. A reinterpretation of beneficence equilibrates the rights of patients physicians. Non wickedness, first of all not to harm, a Hippocratic idea to prevent iatrogenesis and Justice, to maintain personal, social and political equity. These principles are a language, an ethical analysis methodology and give clues for our relationship with patients. They are a guide for personal analysis, reflection and change and show a collective and individual path to incorporate ethics to our daily work.

Gastricsin and cathepsin D in normal and hypertrophic human prostates.

The relative contents of gastricsinogen, the inactive zymogen precursor of gastric gastricsin (EC 3.4.23.3), and cathepsin D (EC 3.4.23.5) in normal and benign hyperplasia of the prostate gland have been determined. Gastricsinogen levels are significantly lower (0.116 +/- 0.02 U/gm. wet tissue) in the hyperplastic than in normal prostates (0.65 +/- 0.06 U/gm.). Conversely, cathepsin D levels are higher in the diseased (0.705 +/- 0.17 U/gm.) as opposed to normal prostatic tissue (0.39 +/- 0.12 U/gm.). The average gastricsin-cathepsin D differences between the 2 tissues (0.26 +/- 0.025 for normal prostates and -0.59 +/- 0.057 SEM for hyperplastic tissue) are also significantly different (p less than 0.001). It is suggested that the simple determination of these 2 acid proteinases in prostate homogenates could be used as alternative and complementary marker enzymes for the study of the physiopathologic status of the prostate gland.
