Dermatology: The art of purifying yourself through the skin

Among scientific specialties, dermatology is the one that closest to the precepts and techniques of cosmetological aesthetics. This is in charge of the study of the structure and functions of the skin and purifying the skin, in addition to treating the diseases pharmacologically. Dermatologists are doctors who, after completing the degree, which has an average duration of 4 years, specialize in dermatology and become suitable in diagnosing, preventing and indicating the most appropriate treatment. Skin diseases are sometimes isolated as vitiligo, however, on other occasions they are externalizations of internal ailments, as occurs in skin cancer and other conditions. In addition to knowing about infectious diseases, they must have knowledge of immunology, neurology, rheumatology and endocrinology. Cosmetic dermatology: It is a subspecialty of this branch of health that uses various techniques of cosmetics and appliances to treat scars left by acne using the laser, application of...

NUCLEAR MEDICINE

Nuclear medicine has become an indispensable tool in the diagnosis and treatment of various diseases. This medical specialty uses radioisotopes, radioactive substances that emit energy in the form of gamma rays or beta particles, to obtain functional images of the human body and treat diseases accurately and effectively.


Concept of Nuclear Medicine:**

Nuclear medicine is based on the principle that certain organs and tissues of the human body absorb radioisotopes differently. When administering a specific radiopharmaceutical to the patient, it accumulates in the target areas, allowing special gamma cameras to detect emitted radiation and generate detailed images of the internal functioning of the body.

Types of nuclear medicine:**

Nuclear medicine is divided into two main branches: diagnosis and therapy.

1. Diagnostic Nuclear Medicine:** Diagnostic nuclear medicine uses radioisotopes to obtain functional images of the human body, providing valuable information about the function of organs and tissues, blood flow, metabolic activity and the presence of diseases. Some of the most common diagnostic tests include:

* Scans:** Allow visualization of radiopharmaceutical distribution in the body, identifying abnormalities in the function or structure of organs such as the heart, bones, kidneys, liver, brain and the lungs.

* Positron emission tomography (PET):** Combines nuclear medicine with computed tomography (CT) to generate three-dimensional high-resolution images of the body's metabolic activity, being useful for the diagnosis of cancer, heart disease and neurological disorders.

* Hybrid Nuclear Medicine studies:** Combine nuclear medicine with other imaging techniques, such as nuclear magnetic resonance imaging (NMR) or CT, to obtain even more complete information on the structure and function of the body.

**2. Therapeutic Nuclear Medicine:** Therapeutic nuclear medicine uses radioisotopes to destroy diseased cells precisely, minimizing damage to healthy tissues. Some of the most common treatments include: * **Radioisotopic therapy:** Administers intravenous or intra-arterial radioisotopes to directly attack cancer cells, being useful for the treatment of malignant tumors in various organs, such as the thyroid, bones and liver. * **Molecular Nuclear Medicine:** Use radioisotopes attached to specific molecules to selectively attack diseased cells, such as cancer cells or infected cells.

**Objectives of nuclear medicine in medical services:** Nuclear medicine has as main objectives:

* **Precise diagnosis of diseases:** It allows identifying the cause and scope of various diseases in a precise and non-invasive way, facilitating timely medical decision-making.

* **Treatment evaluation:** Allows you to monitor the response to treatment effectively, determining if the treatment is effective and making adjustments as necessary.

* Illness prognosis:** Provides valuable information on the prognosis of the disease, helping to predict the evolution of the patient and plan long-term treatment.

* MEDICAL INVESTIGATION: Contributes to the advancement of medical knowledge through the study of the mechanisms of diseases and the development of new radiopharmaceuticals and diagnostic and treatment techniques.

Conclusion:** Nuclear medicine has revolutionized the diagnosis and treatment of various diseases, offering precise and effective tools to improve the health of patients. Its continuous development and constant research allow us to expand its scope and applications in the medical field, opening new possibilities for health care.

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...

ALTERNATIVE MEDICINE

Alternative medicine, also known as complementary and integrative medicine (MCI), encompasses a wide spectrum of practices and approaches that are not part of conventional medicine. These therapies are used to treat or prevent diseases, improve general well-being and complement traditional medical treatments. Types of alternative medicine: The MCI can be classified into various categories, some of the most common are: * Complete Medical Systems:** Ayurveda, Traditional Chinese Medicine, Homeopathy. * Mind-Body Techniques:** Yoga, Meditation, Tai Chi, Mindfulness. * Biology-based practices:** Phytotherapy, nutrition, dietary supplements. * Manipulative therapies:** Chiropractic, osteopathy, therapeutic massage. * Energy therapies:** Reiki, acupuncture, biomagnetism.
