A 12-year-old patient case is reported, presented with a desmoid fibroma of the left pterygoid region, extended to the cortical and endosteal regions of the mandible, reconstructed immediately with a free peroneal flap, recovering with this both form and function. To date, 3 years from surgery, he has no complications. Evolution of this case and a brief review of the literature is reported. It is concluded that free peroneal graft for mandible reconstruction is safe and has excellent results, both aestethic and functional.

Cardiovascular disease is the leading cause of mortality in Mexico, as well as in other Western countries. Conventional risk factors for atherosclerosis, such as cigarette smoking, systemic hypertension, diabetes mellitus, and hypercholesterolemia, do not explain this association completely. ⋯ Elevated plasma levels of this amino acid (higher than 15 mmol/L or lower in the presence of other cardiovascular risk factors) promote the development of atherosclerosis. Folic acid and vitamin B6 and B12 supplements decrease plasma levels of homocysteine effectively and may play an important role in the prevention and treatment of atherosclerotic vascular disease.

We review death, thanatology and bioethics concepts and precepts, the value scale and hierarchization; the changes in death vision according to culture, religion and hierarchy, changes in perception of, according to culture, religion and mores in different communities and times, as well with scientific and technological advances. We analyzed patient's reactions to death, and the reactions of people close to them. We describe and analyze the principal bioethical dilemmas associated with death: therapeutic overkill or dysthanasia, passive and active euthanasia, assisted suicide, orthothanasia, and organ transplants. We discuss the relationship between death and science, bioethics and thanatology, as a necessary discipline today.

Multicenter Study Clinical Trial
[Safety and efficiency of Echogen. Transthoracic echocardiography study].
This study was performed to determine the safety and efficacy of intravenous dodecafluoropentane emulsion (Echo Gen), to determine the efficacy and duration of contrast agent in left cavities by transthoracic echocardiography and to evaluate the clinical impact of Echogen. Fifteen patients were studied, by transthoracic echocardiography. Duration of contrast intensity of left ventricular cavity opacification and endocardial border definition were studied. The adverse effects were assessed immediately, 24 hours and 7 days after Echogen. Both the vital signs and electrocardiogram did not show any significant changes. Minimal changes in hepatic function in one patient and in renal function in other one were observed. The mean duration of left ventricular opacification was 4 minutes 47 seconds and full or intermediate opacification was more frequently observed after Echogen. Endocardial border delineation was poor in one patient, intermediate in five and excellent in nine. In 86.7% the diagnostic information obtained was sufficiently and allowed other studies. ⋯ This study demonstrates that Echogen is effective for Left ventricular cavity opacification, endocardial border definition and assessment of left ventricular volume and ejection fraction 2) The obtained information with the use of Echogen allowed other studies. 3) The intravenous administration of Echogen is safe in doses of 0.05 ml/Kg.
