Comparative Study Clinical Trial
Detection of myocardial viability could be improved by rest GIK (glucose-insulin-potassium solution)-Tc 99m sestamibi compared with TL-201 reinjection, in post myocardial infarction patients.
GIK solutions improve detection of myocardium viability after acute infarction because they could change the metabolic conditions, improving myocardial perfusion defects. ⋯ Our data suggest that GIK-MIBI protocol is a safe and easy procedure which improves the detection of perfusion reversible defects compared with Tl-201 reinjection, obtaining better information regarding myocardial viability, with lower acquisition time and less cost.

To evaluate the impact of a triage system on waiting times and patient satisfaction of one secondary care hospital emergency department (ED). ⋯ The triage system largely challenged the not easy ED demand and its waiting times in addition to patient satisfaction. This simple classification scale allows improvement in managing emergency services and cases, the benefits can be potentially extended to other health care services.

Mucormycosis is an invasive fungal infection that affects decompensated diabetics, immunosupressed patients and occasionally healthy individuals. Despite advances in anti-fungal therapy and surgical techniques, the morbidity and mortality remain high. Adjuvant hyperbaric oxygen therapy (HBO) has been proposed based on pathophysiology and several favorable clinical reports. ⋯ Considering the pathophysiology of mucormycosis adjuvant HBO therapy seems reasonable. However, the clinical experience is still too limited to make HBO part of the standard of care. Prospective, randomized, controlled trials will help to define the role of HBO in this devastating infection.

[The surgery and its teaching in Mexico. Historical review 1325-2000].
To relate the outstanding events in the surgical teaching in Mexico since 1325 to 2000. ⋯ The teaching of surgical procedures has been pretty much alike in many cultures around the world, even though this did not happened at the same time in all places; a very good example of this are surgical teachings in ancient Egypt, Greece and Mexico separated by 4,300 and 1,900 years respectively whose surgical methods and its teaching are quite similar. Afterwards the influence of Spanish, French, German and American medical cultures developed faster and efficient changes with the main objective of obtain every time better surgeons.

The idea of transfusing blood of an animal to another or from an animal to a man or from one to another man, is very ancient. When the doctrine of blood circulation was diffused, in the first third of the XVII century, this idea was give fresh impetus. On began also to inject some substance into the blood, wich will permit to introduce medicaments intravenously. ⋯ At the time persisted the problem of blood coagulation, which could be resolved during the XX century in North America (Crile, 1906) as well as in Latin America (Luis Agote, 1914). Moreover the blood groups were described in 1900 by the Austrian physician Karl Landsteiner, who identified later the Rh factor. It seems completely justified the inscription shining on the façade of the National Archive in Washington: "The past is only prologue".
