In addition to the increase in the average life expectancy of Mexicans, obesity, diabetes, cardiovascular diseases, various types of arthritis, are largely due to changes in their diet: they became more consumers of carbohydrates -we have the first place as consumers of soft drinks in the world-, a sedentary lifestyle due to the use of 2 screens that appeared in the last five years -the computer screen and the television screen- and the changes in urban life.
Fifty years ago, the inhabitants of Mexican cities used to walk around the city, but today, fearful of insecurity, they travel by vehicle even for short trips.
Its frequency of various types of cancer has increased, those of the breast and uterus in women, and those of the respiratory tract due to smoking in men. Pneumonia and tuberculosis no longer appear among the 10 leading causes of death and others appear, as can be seen in the tables presented.
Also in this second half of the century
New and dangerous diseases appeared, such as acquired immunodeficiency syndrome (AIDS), and others increased in severity, such as tuberculosis, which became a disease difficult to treat due to resistance to antibiotics, which mid-century promised safe treatment of her. Viruses seem to have replaced, in part, bacteria, and the problem with the latter in general is the appearance of resistance to antibiotics, which in some way – like many other drugs – are used without medical supervision.
Advances in diagnostic methods
To diagnose diseases, a doctor at the beginning of the 20th century had a fundamental element: the interview with the patient. This peculiar relationship in which the patient confided his illnesses and fears to the doctor and the doctor tried to understand the disease by assessing the symptoms that the patient reported, generated an understanding of the disease that the doctor completed with a thorough physical examination of the patient.
patient, which focused primarily on the region of the body that seemed to be affected by the disease, but was not limited to it. It was said, and rightly so, that the good doctor was the one who spent the most time learning about the discomforts reported by the patient and the one who explored the patient the most extensively.
The physician at the turn of the century had a limited number of simple laboratory tests and radiological studies to use as aids in establishing a diagnosis.
Currently diagnostic resources have increased considerably
The laboratory tests with which chemical, hormonal, and cellular constants of the organism can be explored today number in the hundreds, with methods as modern as constantly obtaining values of these elements. Auxiliary cabinet methods in patient examination, which began with radiology, today offer methods such as computerized axial tomography in various versions, magnetic resonance imaging and positron emission tomography (PET); With these methods, the tissues of a human being can be explored as in a vivisection.
This last method increases the possibilities of diagnosis.
In endoscopy exploration today it is possible to explore practically all the cavities of the human being, with flexible fiber optic endoscopes, which make these explorations highly valuable and precise auxiliaries without the inconvenience caused by endoscopy with rigid instruments.
- In the treatment of diseases, the great advances in drug therapy and advances in surgical techniques are a great change, which through the use of endoscopic instruments have achieved simple recovery surgeries with less morbidity.
- All these advances, barely outlined, are so large and complex that a book could be written just to mention them all. Today’s medicine would be glorious if some disturbing elements had not been inserted into it.
