Hair Tourniquet
Hair tourniquet is a condition where hair or thread becomes tightly wrapped around most commonly a toe, and occasionally a finger, genitals, or other body parts. This results in pain and swelling of the affected part. Complications can include tissue death due to lack of blood flow. It occurs most commonly among children around 4 months of age, though cases have been described in older children and adults. Most cases occur accidentally. Risk factors may include autism and trichotillomania. The mechanism is believed to involve wet hair become wrapped around a body part and then tightening as it dries. Diagnosis involves examination of the entire child. Prevention is by keeping the parent's hair from contact with the baby such as by the parent keeping their hair brushed and back and washing the baby's clothing separately. Treatment is with a substance that breaks down hair or cutting through the hair. The condition is rare. Males and females are equally frequently affected. Th ...

Autoamputation
Autoamputation is the spontaneous detachment (amputation) of an appendage or organ from the body. This is not to be confused with self-amputation. It is usually due to destruction of the blood vessels feeding an extremity such as the finger tips. Once the vessels are destroyed, the tissue is starved of oxygen and dies, which is often followed by gangrene. Autoamputation is a feature of ainhum, cryoglobulinemia and thromboangiitis obliterans. In 1881, Thornton made the case of autoamputation. Autoamputation could be the result of severe cases of certain chronic wounds, such as frostbite. These chronic wounds might be due to some vascular and pathogenic conditions like Buerger disease or Reynaud's phenomenon. Also, uncontrolled diabetes can predispose one to autoamputation. However, autoamputation has been described as spontaneous. Autoamputation has often been associated with fingers and toes but other parts of the body can suffer this condition as well. There have been reported ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arteries
An artery (plural arteries) () is a blood vessel in humans and most animals that takes blood away from the heart to one or more parts of the body (tissues, lungs, brain etc.). Most arteries carry oxygenated blood; the two exceptions are the pulmonary and the umbilical arteries, which carry deoxygenated blood to the organs that oxygenate it (lungs and placenta, respectively). The effective arterial blood volume is that extracellular fluid which fills the arterial system. The arteries are part of the circulatory system, that is responsible for the delivery of oxygen and nutrients to all cells, as well as the removal of carbon dioxide and waste products, the maintenance of optimum blood pH, and the circulation of proteins and cells of the immune system. Arteries contrast with veins, which carry blood back towards the heart. Structure The anatomy of arteries can be separated into gross anatomy, at the macroscopic level, and microanatomy, which must be studied with a microscop ...

Injuries
An injury is any physiological damage to living tissue caused by immediate physical stress. An injury can occur intentionally or unintentionally and may be caused by blunt trauma, penetrating trauma, burning, toxic exposure, asphyxiation, or overexertion. Injuries can occur in any part of the body, and different symptoms are associated with different injuries. Treatment of a major injury is typically carried out by a health professional and varies greatly depending on the nature of the injury. Traffic collisions are the most common cause of accidental injury and injury-related death among humans. Injuries are distinct from chronic conditions, psychological trauma, infections, or medical procedures, though injury can be a contributing factor to any of these. Several major health organizations have established systems for the classification and description of human injuries. Occurrence Injuries may be intentional or unintentional. Intentional injuries may be acts of vio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tourniquet
A tourniquet is a device that is used to apply pressure to a limb or extremity in order to stop the flow of blood. It may be used in emergencies, in surgery, or in post-operative rehabilitation. A simple tourniquet can be made from a stick and a rope, but the use of makeshift tourniquets has been reduced over time due to their ineffectiveness compared to a commercial and professional tourniquet. This may stem the flow of blood, but side effects such as soft tissue damage and nerve damage may occur. Types There are three types of tourniquets: surgical tourniquets, emergency tourniquets, and rehabilitation tourniquets. Surgical tourniquets Silicone ring tourniquets, or elastic ring tourniquets, are self-contained mechanical devices that do not require any electricity, wires or tubes. The tourniquet comes in a variety of sizes. To determine the correct product size, the patient's limb circumference at the desired occlusion location should be measured, as well as their bloo ...

Nair (hair Removal)
Nair is a hair-removal product manufactured by Church & Dwight. It was purchased from Carter-Wallace in 2001 via a partnership with Kelso. Also in 2001 Nair introduced its line of men's products. Nair is a portmanteau of "No hair." The brand is mainly known for its depilatories that work by breaking the disulfide bonds of the keratin molecules in hair. This reduces the tensile strength of the keratin so greatly that the hair can be wiped away. Nair's slogans include: ''"The Less That You Wear the less you have to fix your hair'', ''the More You Need Nair!"''; ''"Like Never Before"''; and ''"We wear short shorts, Nair for short shorts"''. The initial ad for the "short shorts" commercial won a Clio. It was based on the 1958 song "Short Shorts". As of 2007, Nair had 25 products ranging from hair removal waxes to bleaches. Active ingredients Calcium hydroxide is an active ingredient that chemically breaks down the hair for removal. Some formulations also contain potassium thiog ...

Depilatory
Hair removal, also known as epilation or depilation, is the deliberate removal of body hair or head hair. Hair typically grows all over the human body and can vary in thickness and length across human populations. Hair can become more visible during and after puberty and men tend to have thicker, more visible body hair than women.) Both males and females have visible body hair on the head, eyebrows, eyelashes, armpits, genital area, arms, and legs. Males and some females may also have thicker hair growth on their face, abdomen, back, buttocks, anus, areola, chest, nasal, and ear. Hair does not generally grow on the lips, the underside of the hands or feet, or on certain areas of the genitalia. Hair removal may be practiced for cultural, aesthetic, hygienic, sexual, medical, or religious reasons. Forms of hair removal have been practiced in almost all human cultures since at least the Neolithic era. The methods used to remove hair have varied in different times and regions. The ...

Hair Tourniquet After
Hair is a protein filament that grows from follicles found in the dermis. Hair is one of the defining characteristics of mammals. The human body, apart from areas of glabrous skin, is covered in follicles which produce thick terminal and fine vellus hair. Most common interest in hair is focused on hair growth, hair types, and hair care, but hair is also an important biomaterial primarily composed of protein, notably alpha-keratin. Attitudes towards different forms of hair, such as hairstyles and hair removal, vary widely across different cultures and historical periods, but it is often used to indicate a person's personal beliefs or social position, such as their age, sex, or religion. Overview The word "hair" usually refers to two distinct structures: #the part beneath the skin, called the hair follicle, or, when pulled from the skin, the bulb or root. This organ is located in the dermis and maintains stem cells, which not only re-grow the hair after it falls out, but also ...

Ischemia
Ischemia or ischaemia is a restriction in blood supply to any tissue, muscle group, or organ of the body, causing a shortage of oxygen that is needed for cellular metabolism (to keep tissue alive). Ischemia is generally caused by problems with blood vessels, with resultant damage to or dysfunction of tissue i.e. hypoxia and microvascular dysfunction. It also implies local hypoxia in a part of a body resulting from constriction (such as vasoconstriction, thrombosis, or embolism). Ischemia causes not only insufficiency of oxygen, but also reduced availability of nutrients and inadequate removal of metabolic wastes. Ischemia can be partial (poor perfusion) or total blockage. The inadequate delivery of oxygenated blood to the organs must be resolved either by treating the cause of the inadequate delivery or reducing the oxygen demand of the system that needs it. For example, patients with myocardial ischemia have a decreased blood flow to the heart and are prescribed with medi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Veins
Veins are blood vessels in humans and most other animals that carry blood towards the heart. Most veins carry deoxygenated blood from the tissues back to the heart; exceptions are the pulmonary and umbilical veins, both of which carry oxygenated blood to the heart. In contrast to veins, arteries carry blood away from the heart. Veins are less muscular than arteries and are often closer to the skin. There are valves (called ''pocket valves'') in most veins to prevent backflow. Structure Veins are present throughout the body as tubes that carry blood back to the heart. Veins are classified in a number of ways, including superficial vs. deep, pulmonary vs. systemic, and large vs. small. * Superficial veins are those closer to the surface of the body, and have no corresponding arteries. *Deep veins are deeper in the body and have corresponding arteries. *Perforator veins drain from the superficial to the deep veins. These are usually referred to in the lower limbs and feet. *Communic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bedwetting
Nocturnal enuresis, also informally called bedwetting, is involuntary urination while asleep after the age at which bladder control usually begins. Bedwetting in children and adults can result in emotional stress. Complications can include urinary tract infections. Most bedwetting is a developmental delay—not an emotional problem or physical illness. Only a small percentage (5 to 10%) of bedwetting cases have a specific medical cause. Bedwetting is commonly associated with a family history of the condition. Nocturnal enuresis is considered ''primary'' when a child has not yet had a prolonged period of being dry. ''Secondary'' nocturnal enuresis is when a child or adult begins wetting again after having stayed dry. Treatments range from behavioral therapy, such as bedwetting alarms, to medication, such as hormone replacement, and even surgery such as urethral dilatation. Since most bedwetting is simply a developmental delay, most treatment plans aim to protect or improve sel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Autism
The autism spectrum, often referred to as just autism or in the context of a professional diagnosis autism spectrum disorder (ASD) or autism spectrum condition (ASC), is a neurodevelopmental condition (or conditions) characterized by difficulties in social interaction, verbal and nonverbal communication, and the presence of repetitive behavior and restricted interests. Other common signs include unusual responses to sensory stimuli. Autism is generally understood as a ''spectrum disorder'', which means that it can manifest differently in each person: any given autistic individual is likely to show some, but not all, of the characteristics associated with it, and the person may exhibit them to varying degrees. Some autistic people remain nonspeaking over the course of their lifespan, while others have relatively unimpaired spoken language. There is large variation in the level of support people require, and the same person may present differently at varying times. Historically ...
