RESUMO
Invasive amebiasis is a very serious health problem in Mexico as it is presumably related to the presence of virulent strains of Entamoeba histolytica and poor hygienic and sanitary conditions; other factors related to invasive amebiasis are undernutrition, alcoholism, and homosexuality. We present three patients with pulmonary amebic hematogenous abscess. Clinically all patients had the typical "chocolate" exudate. The three patients had pulmonary consolidations by chest roentgenogram; one of them had multiple opacities with air fluid level, and the others had an isolated opacity with air fluid level. The ultrasound and hepatogammagram were negative for diaphragmatic communication in all; in one of them the pneumoperitoneum was negative for diaphragmatic communication. The transthoracic needle biopsy of the lesions was positive to ameba in two patients. The serologic tests were positive in all. We treated the patients with metronidazole and emetine during 10 days; since the clinical picture and the radiologic findings did not remit completely, we gave a second course of metronidazole during 10 days more and achieved complete resolution.

Ethical values and principles are singular and immutable, but this is not true of their interpretation and application. In Mexico, even though these values and principles are respected in medical practice, the teaching of bioethics is non-existent and in most of the schools for health professionals the subject is not included in the curriculum. Nevertheless, Mexican society has made notable progress in the legislation and regulation of ethical aspects of such activities as research on human subjects, fertility regulation, the right to death with dignity, organ transplants, and AIDS.

In Mexico, as in many other countries, there are numerous situations involving bioethics that are not necessarily covered by officially sanctioned policies or guidelines. In such cases, it is reasonable to describe commonly accepted rules, opinions, and practices in a general way so as to illustrate how bioethical questions are being managed. This article describes certain goals and practices relating to education in bioethics in Mexico. It then outlines Mexican laws and procedures governing research on human subjects, cites certain official rules and activities relating to regulation of human reproduction, quotes literature dealing with intervention in human procreation, discusses artificial prolongation of life, describes laws and practices governing organ transplants, considers ethical issues relating to such transplants, reviews the AIDS situation, and describes how the need for confidentiality is dealt with in managing AIDS cases and related data. In this manner it indicates how bioethical questions in these various areas are being handled and points out certain priority areas needing work.
