Collagen Induction Therapy
Collagen induction therapy (CIT), also known as microneedling, dermarolling, or skin needling, is a Medical aesthetics, cosmetic procedure that involves repeatedly puncturing the Human skin, skin with tiny, sterile needles (microneedling the skin). CIT should be separated from other contexts in which microneedling devices are used on the skin (e.g., transdermal drug delivery, vaccination). It is a technique for which research is ongoing, but has been used for a number of skin problems including scarring and acne. Some studies have also shown that, when combined with minoxidil treatment, microneedling is able to treat hair loss more effectively than minoxidil treatment alone. Platelet-rich plasma (PRP) can be combined with collagen induction therapy treatment in a form of dermatology, dermatologic autologous blood therapy. PRP is derived from the patient's own blood and may contain growth factors that increase collagen production. It can be applied topically to the entire treatment ...

Medical Aesthetics
Aesthetic medicine is a broad term for specialties that focus on altering cosmetic appearance through the treatment of conditions including scars, skin laxity, wrinkles, moles, liver spots, excess fat, cellulite, unwanted hair, skin discoloration, and spider veins. Traditionally, it includes dermatology, oral and maxillofacial surgery, reconstructive surgery and plastic surgery, surgical procedures ( liposuction, facelifts, breast implants, Radio frequency ablation), non-surgical procedures ( radio frequency skin tightening, non- surgical liposuction, chemical peel, high-intensity focused electromagnetic field, radio frequency fat removal), and a combination of both. Aesthetic medicine procedures are usually elective. Statistics *Worldwide, there were 20 million aesthetic procedures performed from 2014-2015. Cosmetic surgery is a major driver of medical tourism. In February 2018 the president of the British Association of Aesthetic Plastic Surgeons said operations were pe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Human Skin
The human skin is the outer covering of the body and is the largest organ of the integumentary system. The skin has up to seven layers of ectodermal tissue guarding muscles, bones, ligaments and internal organs. Human skin is similar to most of the other mammals' skin, and it is very similar to pig skin. Though nearly all human skin is covered with hair follicles, it can appear hairless. There are two general types of skin, hairy and glabrous skin (hairless). The adjective ''cutaneous'' literally means "of the skin" (from Latin ''cutis'', skin). Because it interfaces with the environment, skin plays an important immunity role in protecting the body against pathogens and excessive water loss. Its other functions are insulation, temperature regulation, sensation, synthesis of vitamin D, and the protection of vitamin B folates. Severely damaged skin will try to heal by forming scar tissue. This is often discoloured and depigmented. In humans, skin pigmentation (a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transdermal
Transdermal is a route of administration wherein active ingredients are delivered across the skin for systemic distribution. Examples include transdermal patches used for medicine delivery. The drug is administered in the form of a patch or ointment that delivers the drug into the circulation for systemic effect. Techniques Obstacles Although the skin is a large and logical target for drug delivery, its basic functions limit its utility for this purpose. The skin functions mainly to protect the body from external penetration (by e.g. harmful substances and microorganisms) and to contain all body fluids. There are two important layers to the human skin: (1) the Epidermis and (2) the Dermis. For transdermal delivery, drugs must pass through the two sublayers of the epidermis to reach the microcirculation of the dermis. The Stratum corneum is the top layer of the skin and varies in thickness from approximately ten to several hundred micrometres, depending on the region of the b ...

Vaccination
Vaccination is the administration of a vaccine to help the immune system develop immunity from a disease. Vaccines contain a microorganism or virus in a weakened, live or killed state, or proteins or toxins from the organism. In stimulating the body's adaptive immunity, they help prevent sickness from an infectious disease. When a sufficiently large percentage of a population has been vaccinated, herd immunity results. Herd immunity protects those who may be immunocompromised and cannot get a vaccine because even a weakened version would harm them. The effectiveness of vaccination has been widely studied and verified. Vaccination is the most effective method of preventing infectious diseases; widespread immunity due to vaccination is largely responsible for the worldwide eradication of smallpox and the elimination of diseases such as polio and tetanus from much of the world. However, some diseases, such as measles outbreaks in America, have seen rising cases due to relati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acne
Acne, also known as ''acne vulgaris'', is a long-term skin condition that occurs when dead skin cells and oil from the skin clog hair follicles. Typical features of the condition include blackheads or whiteheads, pimples, oily skin, and possible scarring. It primarily affects skin with a relatively high number of oil glands, including the face, upper part of the chest, and back. The resulting appearance can lead to anxiety, reduced self-esteem, and, in extreme cases, depression or thoughts of suicide. Susceptibility to acne is primarily genetic in 80% of cases. The roles of diet and cigarette smoking in the condition are unclear, and neither cleanliness nor exposure to sunlight appear to play a part. In both sexes, hormones called androgens appear to be part of the underlying mechanism, by causing increased production of sebum. Another common factor is the excessive growth of the bacterium ''Cutibacterium acnes'', which is present on the skin. Treatments for acne a ...

Minoxidil
Minoxidil, sold under the brand name Rogaine among others, is a medication used for the treatment of high blood pressure and pattern hair loss. It is an antihypertensive vasodilator. It is available as a generic medication by prescription in oral tablet form and over the counter as a topical liquid or foam. Medical uses Minoxidil, when used for hypertension, is generally reserved for use in severe hypertension patients who can not respond to at least two agents and a diuretic. Minoxidil is also generally administered with a loop diuretic to prevent sodium and potassium retention. It may also cause a reflex tachycardia and thus is prescribed with a beta blocker. Minoxidil, applied topically, is widely used for the treatment of hair loss. It is effective in helping promote hair growth in people with androgenic alopecia regardless of sex. Minoxidil must be used indefinitely for continued support of existing hair follicles and the maintenance of any experienced hair regrowth. ...

Platelet-rich Plasma
Platelet-rich plasma (PRP), also known as autologous conditioned plasma, is a concentrate of platelet-rich plasma protein derived from whole blood, centrifuged to remove red blood cells. Though promoted to treat an array of medical problems, evidence for benefit is mixed as of 2020, with some evidence for use in certain conditions and against use in other conditions. As a concentrated source of blood plasma and autologous conditioned plasma, PRP contains several different growth factors and other cytokines that can stimulate healing of soft tissue and joints. There are some indications for use in sports medicine and orthopedics (acute muscle strains, tendinopathy and muscle-fascial injuries and osteoarthritis), or dermatology (androgenic alopecia, wound healing, and skin rejuvenation) or even in proctology (fistula-in-ano). For preparation of PRP, various protocols are used, with an underlying principle of concentrating platelets to 3–5 times physiological levels, then inject ...

Dermatology
Dermatology is the branch of medicine dealing with the skin.''Random House Webster's Unabridged Dictionary.'' Random House, Inc. 2001. Page 537. . It is a speciality with both medical and surgical aspects. A dermatologist is a specialist medical doctor who manages diseases related to skin, hair, nails, and some cosmetic problems. Etymology Attested in English in 1819, the word "dermatology" derives from the Greek δέρματος (''dermatos''), genitive of δέρμα (''derma''), "skin" (itself from δέρω ''dero'', "to flay") and -λογία '' -logia''. Neo-Latin ''dermatologia'' was coined in 1630, an anatomical term with various French and German uses attested from the 1730s. History In 1708, the first great school of dermatology became a reality at the famous Hôpital Saint-Louis in Paris, and the first textbooks (Willan's, 1798–1808) and atlases ( Alibert's, 1806–1816) appeared in print around the same time.Freedberg, et al.

Autologous Blood Therapy
Autologous blood therapy, also known as autologous blood injection or autohemotherapy, comprises certain types of hemotherapy using a person's own blood ('' auto-'' + '' hemo-'' + ''therapy''). There are several kinds, the original belonging only to traditional medicine, alternative medicine and some newer kinds under investigation. The original, unscientific form is "the immediate intramuscular or subcutaneous reinjection of freshly drawn autologous blood". . It was used in the early 20th century, when some physicians believed that it had efficacy and logical mechanism of action; it was abandoned later as advancing science made clear that it lacked those.

Growth Factor
A growth factor is a naturally occurring substance capable of stimulating cell proliferation, wound healing, and occasionally cellular differentiation. Usually it is a secreted protein or a steroid hormone. Growth factors are important for regulating a variety of cellular processes. Growth factors typically act as signaling molecules between cells. Examples are cytokines and hormones that bind to specific receptors on the surface of their target cells. They often promote cell differentiation and maturation, which varies between growth factors. For example, epidermal growth factor (EGF) enhances osteogenic differentiation, while fibroblast growth factors and vascular endothelial growth factors stimulate blood vessel differentiation (angiogenesis). Comparison to cytokines ''Growth factor'' is sometimes used interchangeably among scientists with the term ''cytokine.'' Historically, cytokines were associated with hematopoietic (blood and lymph forming) cells and immune syste ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Infection Control
Infection prevention and control is the discipline concerned with preventing healthcare-associated infections; a practical rather than academic sub-discipline of epidemiology. In Northern Europe, infection prevention and control is expanded from healthcare into a component in public health, known as "infection protection" (''smittevern, smittskydd, Infektionsschutz'' in the local languages). It is an essential part of the infrastructure of health care. Infection control and hospital epidemiology are akin to public health practice, practiced within the confines of a particular health-care delivery system rather than directed at society as a whole. Infection control addresses factors related to the spread of infections within the healthcare setting, whether among patients, from patients to staff, from staff to patients, or among staff. This includes preventive measures such as hand washing, cleaning, disinfecting, sterilizing, and vaccinating. Other aspects include surveillan ...

Vox (website)
''Vox'' () is an American news and opinion website owned by Vox Media. The website was founded in April 2014 by Ezra Klein, Matt Yglesias, and Melissa Bell, and is noted for its concept of explanatory journalism. Vox's media presence also includes a YouTube channel, several podcasts, and a show presented on Netflix. ''Vox'' has been described as left-of-center and progressive. History Prior to founding ''Vox'', Ezra Klein worked for ''The Washington Post'' as the head of Wonkblog, a public policy blog. When Klein attempted to launch a new site using funding from the newspaper's editors, his proposal was turned down and Klein subsequently left ''The Washington Post'' for a position with Vox Media, another communications company, in January 2014. ''The New York Times'' David Carr associated Klein's exit for ''Vox'' with other "big-name journalists" leaving newspapers for digital start-ups, such as Walter Mossberg and Kara Swisher (of '' Recode'', which was later acqu ...
