[Communications difficulties during the medical interview].

The aims of medical interview are to obtain diagnostic information, to obtain an empathetic communication with the patient, to educate him about his disease and to establish a personal link allowing a lasting relationship. We analyze some features of communication with patients. Individualized communication, recognizing his identity and personal aspects, "looking from the patient". Context, a shared but not mentioned value, part of the world of emotions and ideas. An analog and digital language, the former precise in words and the latter more diffuse, with gestures, not verbal. Coherence, as the similitude between what we think, feel and say. If there is no coherence, communication is impaired. Emotions, always present, rending communication more valid and real. We need to recognize, express and respond to emotions. An emotionless patient becomes a distant and impersonal object, an "it". When emotions are incorporated the patient is a "him" with whom I share and dialog. Empathy is an emotional comprehension, a personal bond. It improves relationships and creates links. Compassion is a variation of empathy that includes spiritual aspects and values. Negative emotions as rage, frustration and aggression creates communicational difficulties. We must recognize, express and clarify them to improve the situation. Difficult patients with whom communication is difficult such as confuse, agitated, terminal, elder, manipulating or hypochondriac subjects. The idea of transference and counter transference in these complicated situations is analyzed.

Communication

[General features of the patient-physician relationship].

The communication between physicians and patients is often deficient. Little time is devoted to it and the patient receives scanty information with a low emotional content. Some features of our medicine can explain this situation. The rationalist and mechanistic biological model, allows to study only those things that can be undertaken with the scientific method. Psychological, social and spiritual aspects are surpassed. It only looks at material aspects of people, limiting the communication. Patients express their symptoms in an emotional way, with multiple beliefs and fears. The physician converts them to a precise, scientific, measurable and rational medical logical type. This language is not understood by patients, generating hesitancy in the communication. The paternalism is based in the power that physicians have over patients. We give knowledge and ask the patient to subordinate and accept our power. The patient loses his moral right to be informed, to ask, to have doubts or to disagree. Our personal communication is almost always formal, unemotional and with no explanations, further limiting communication.

Communication

[Why do we work in public hospitals? Some ideas to keep in mind].

Why do we work in public hospitals, what do we look for and what do we find working at these places? There are several answers. The heritage, the places where we learnt, the places where medicine is practiced. A model that feeds us. They cannot be improved and it is difficult to accept their limitations. However, many factors such as teaching, research and group work, encourage us to continue working in them. Variation and simultaneity, they are places with many variables, a living organism. The myth, the mother, that transmits its principles and behaviors, gives us a sense of life, feeds us and allows us to feed others. Economical reasons and performance. When performance of physicians is analyzed, positive values such as contact with patients, hours of discussion and study, quality of care, risks, dedication and training difficulties must be taken into consideration. Hospitals are not a patient assembly line. Fantasies and representations. We are participating in a health community and hospitals become a place for personal growth. Respect towards poverty. Helping the less fortunate. Knowledge and learning. Experiencing values. Forgotten words. Bioethics brought back several principles that are present in hospitals such as compassion, empathy, sweetness, service, humility, gratitude.

[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.
