EMERGENCY MEDICINE

Emergency medicine stands as a vital medical specialty within the health landscape, acting as the first line of defense in critical situations that threaten the health and life of patients. Its dynamic and multidisciplinary approach makes it a fundamental pillar for comprehensive health care, providing immediate and specialized support in the most challenging moments". Concept and scope of emergency medicine Emergency medicine is defined as the branch of medicine that is responsible for the evaluation, diagnosis and initial treatment of patients who have acute or traumatic pathologies that compromise their health status immediately. Its scope of action ranges from pre-hospital care, provided at the scene of the incident, to the stabilization and management of the patient in the hospital emergency department.

The culture of a Human Stem Cell laboratory

It was in 1981 when scientists first achieved mouse embryonic stem cell cultures. Although this milestone marked the development of numerous subsequent investigations, until 1998 the culture of a human stem cell laboratory was not achieved. In that year, two teams separately announced that they had isolated and cultivated human stem cells from, in one case, from embryos in the blastocyst phase and, in the other, from aborted fetuses. The research teams were led by biologists John Gearhart, from Johns Hopkins University, and James Thomson, from the University of Wisconsin at Madison. During the 1990s, scientists discovered many other characteristics of these cells, such as adult stem cells from a specific tissue (for example blood), can cause cells from other types of tissues, such as nerve cells (neurons). One of the most interesting results was obtained by researcher Fred Gage at the Salk Institute, who showed that the adult human brain can create new neurons.

Before Gage's discovery, neurobiologists assumed that our brain did not create any new cells after birth. Presumably, this ability comes from the stem cells of this tissue. By the end of the 20th century, researchers had not yet developed any actual clinical application with isolated stem cells and kept in culture. However, doctors used stem cells to treat diseases long before they were isolated. In 1968, scientists successfully developed the first bone marrow transplant, a procedure by which a patient receives an infusion of healthy bone marrow cells. The purpose of such a transplant was to restore the ability of the marrow to generate blood cells in patients who had undergone strong chemotherapy processes, who had deeply damaged that tissue. The researchers suspected that the stem cells present in the bone marrow implant were responsible for such restoration.

Currently, bone marrow transplantation has become a therapy for certain types of cancer (leukemia, lymphoma) and other diseases of the blood or bones. This type of therapy, which consists of extracting stem cells from a tissue to replenish it after damage, could be carried out in other tissues. Currently, there are numerous open lines of research based on stem cells that will allow knowing the mechanisms of cell differentiation and will provide, in the not too distant future, new treatments for various diseases, until now incurable. Some of the therapeutic possibilities offered by stem cells are their use to replace damaged cells and tissues, or their use to test, before doing so in experimental animals or in humans, new drugs.

ORIGIN AND THEORY OF MEDICINE AND NURSING

The knowledge of prehistoric medical practice comes from paleopathology, or study of the pictographs that showed the medical techniques, of the skulls and skeletons, as well as the surgical instruments of ancient societies and non-technological contemporary. Despite the fact that this study concerns anthropology, some of these practices have survived until modern times, which justifies their consideration in the history of medicine. Serious illnesses were of special interest to primitive men even though they could not treat them. They divided the genesis of the disease into two categories, each with a variety of therapies that were mutually exclusive. The first and most numerous were the processes attributed to the influence of malevolent demons, to whom the projection of an alien spirit, a stone or a worm within the body of the trusting patient was attributed. These diseases had to be tackled through spells, dances, sacrifices, spells, talismans and other measures. If in the e...

BRANCHES OF MEDICINE

Medicine, throughout its long history, has experienced a constant evolution, dividing into various specialized branches to offer comprehensive and quality medical care to patients. This specialization process has been driven by scientific and technological advances that have allowed a greater knowledge of the human body and the development of new diagnostic and therapeutic tools. BASIC BRANCHES OF MEDICINE: The basic branches of medicine lay the foundations for the study and practice of medical specialties. Among them we find: * Anatomy:** Study the structure of the human body and its relationships. * Physiology:** Investigates the functioning of the organs and systems of the human body. * Biochemistry:** Analyze the chemical processes that occur in living beings. * PATHOLOGY:** Study the causes, mechanisms and effects of diseases. * Pharmacology:** It is responsible for the study of medicines, their action in the body and their therapeutic applications. THE DOCTORS...

INTERNAL MEDICINE

The field of medicine is divided into various branches and specialties, each with a specific focus and objectives. Among the most important are **internal medicine** and **external medicine**, two areas that, despite sharing the same final objective of preserving the patient's health, differ in their methodology and scope. **Internal Medicine: Deepening complexity** Internal medicine focuses on the diagnosis, treatment and prevention of diseases that affect **adults**. Unlike general medicine, which offers comprehensive primary and preventive care, internal medicine specializes in **complex and chronic pathologies**, which often require a multidisciplinary approach. Internist doctors have extensive training in **physiopathology, clinical diagnosis and management of systemic diseases**. Their work is carried out mainly in hospital settings, where they have the opportunity to evaluate and treat patients with conditions that cover a wide range of specialties, such as: * Car...
