Aerosol Burn
An aerosol frostbite of the skin is an injury to the body caused by the pressurized gas within an aerosol spray cooling quickly, with the sudden drop in temperature sufficient to cause frostbite to the applied area. Medical studies have noted an increase of this practice, known as "frosting", in pediatric and teenage patients. Adiabatic expansion and/or evaporative cooling (with a low boiling temperature) causes the gas to rapidly cool on exit from the aerosol applier. In freeze sprays, a controlled amount of this cooling is useful. Uncontrolled cooling, however, can result in freeze burns to the skin. According to controlled laboratory experiments, the gas from a typical deodorant spray can reduce skin temperature by up to sixty degrees Celsius. The form of injury is freezing of the skin, a type of frostbite. It is highly advised for those who develop frostbite to seek medical attention. In rare cases aerosol-induced burns can be severe enough to necessitate skin grafting. Si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Emergency Medicine
Emergency medicine is the medical specialty concerned with the care of illnesses or injuries requiring immediate medical attention. Emergency physicians (or "ER doctors") specialize in providing care for unscheduled and undifferentiated patients of all ages. As frontline providers, in coordination with emergency medical services, they are responsible for initiating resuscitation, stabilization, and early interventions during the acute phase of a medical condition. Emergency physicians generally practice in hospital emergency departments, pre-hospital settings via emergency medical services, and intensive care units. Still, they may also work in primary care settings such as urgent care clinics. Sub-specialties of emergency medicine include disaster medicine, medical toxicology, point-of-care ultrasonography, critical care medicine, emergency medical services, hyperbaric medicine, sports medicine, palliative care, or aerospace medicine.

Substance Intoxication
Substance intoxication is a transient condition of altered consciousness and behavior associated with recent use of a substance. It is often maladaptive and impairing, but reversible. If the symptoms are severe, the term "substance intoxication delirium" may be used. Slang terms for the state include: getting ''high'' (generic), and being ''stoned'', ''cooked'', or ''fried'' (usually in reference to cannabis). Substance intoxication may often accompany a substance use disorder (SUD); if persistent substance-related problems exist, SUD is the preferred diagnosis. The term "intoxication" in common use most often refers to alcohol intoxication, or drug addiction usually opioids consisting of an overdose; resulting in death. Classification The ICD-10 ''Mental and Behavioural Disorders due to psychoactive substance use'' shows: * F10. alcohol * F11. opioids * F12. cannabinoids * F13. sedatives and hypnotics * F14. cocaine * F15. caffeine * F16. hallucinogens * F17. t ...

Huffing
Inhalants are a broad range of household and industrial chemicals whose volatile vapors or pressurized gases can be concentrated and breathed in via the nose or mouth to produce Substance intoxication, intoxication, in a manner not intended by the manufacturer. They are inhaled at room temperature through volatilization (in the case of gasoline or acetone) or from a pressurized container (e.g., nitrous oxide or butane), and do not include drugs that are sniffed after burning or heating. While a few inhalants are prescribed by medical professionals and used for List of medical inhalants, medical purposes, as in the case of inhaled anesthetics and nitrous oxide (an anxiolytic and pain relief agent prescribed by dentists), this article focuses on inhalant use of household and industrial propellants, glues, fuels, and other products in a manner not intended by the manufacturer, to produce Substance intoxication, intoxication or other psychoactive effects. These products are used as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fluorinated Hydrocarbon
Fluorocarbons are chemical compounds with carbon-fluorine bonds. Compounds that contain many C-F bonds often have distinctive properties, e.g., enhanced stability, volatility, and hydrophobicity. Several fluorocarbons and their derivatives are commercial polymers, refrigerants, drugs, and anesthetics. Nomenclature Perfluorocarbons or PFCs, are organofluorine compounds with the formula CxFy, meaning they contain only carbon and fluorine. The terminology is not strictly followed and many fluorine-containing organic compounds are also called fluorocarbons. Compounds with the prefix perfluoro- are hydrocarbons, including those with heteroatoms, wherein all C-H bonds have been replaced by C-F bonds. Fluorocarbons includes perfluoroalkanes, fluoroalkenes, fluoroalkynes, and perfluoroaromatic compounds. Perfluoroalkanes Chemical properties Perfluoroalkanes are very stable because of the strength of the carbon–fluorine bond, one of the strongest in organic chemistry. Its stre ...

Air Freshener
Air fresheners are products designed to reduce unwanted odors in indoor spaces, to introduce pleasant fragrances, or both. They typically emit fragrance to mask odors but may use other methods of action such as absorbing, bonding to, or chemically altering compounds in the air that produce smells, killing organisms that produce smells, or disrupting the sense of smell to reduce perception of unpleasant smells. There are many different types of air fresheners that deliver their active ingredients in different ways, including sprays, candles, reed diffusers, scented beads, gels, passive and active evaporating diffusers, atomizers, automatically timed metered aerosol dispensers, electric fan air fresheners, and plug-ins. Air fresheners are used in domestic and commercial settings and in both small and large spaces. Some air fresheners are produced for specific spaces and odors, such as Car Freshner, car fresheners and urinal deodorizer blocks. Some air fresheners contain ingredients t ...

Dermatological
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. 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.

Asthma Inhaler
A metered-dose inhaler (MDI) is a device that delivers a specific amount of medication to the lungs in the form of a short burst of aerosolized medicine that is usually self-administered by the patient via inhalation. It is the most commonly used delivery system for treating asthma, chronic obstructive pulmonary disease (COPD) and other respiratory diseases. The medication in a metered dose inhaler is most commonly a bronchodilator, corticosteroid or a combination of both for treating asthma and COPD. Other medications less commonly used but also administered by MDI are mast cell stabilizers, such as cromoglicate or nedocromil. Description A metered-dose inhaler consists of three major components: the canister, which is produced in aluminum or stainless steel by means of deep drawing, where the formulation resides; the metering valve, which allows a metered quantity of the formulation to be dispensed with each actuation; and an actuator (or mouthpiece) which enables the patie ...

Deodorants
A deodorant is a substance applied to the body to prevent or mask body odor caused by bacterial breakdown of perspiration, for example in the armpits, groin, or feet. A subclass of deodorants, called antiperspirants, prevents sweating itself, typically by blocking sweat glands. Antiperspirants are used on a wider range of body parts, at any place where sweat would be inconvenient or unsafe, since unwanted sweating can interfere with comfort, vision, and grip (due to slipping). Other types of deodorant allow sweating but prevent bacterial action on sweat, since human sweat only has a noticeable smell when it is decomposed by bacteria. The first commercial deodorant, Mum, was introduced and patented in the late nineteenth century by an inventor in Philadelphia, Pennsylvania, Edna Murphey. The product was briefly withdrawn from the market in the US. The modern formulation of the antiperspirant was patented by Jules Montenier on January 28, 1941. This formulation was first found in " ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cinnamon Challenge
The cinnamon challenge is a food challenge that gained viral recognition on social media in the early 2010s. Participants generally film themselves attempting to eat a spoonful of ground cinnamon in under 60 seconds without drinking anything. The challenge is difficult and carries substantial health risks because the cinnamon can coat and dry the mouth and throat, possibly resulting in coughing, gagging, vomiting, and inhalation of cinnamon, which can in turn lead to throat irritation, breathing difficulties, and risk of pneumonia or a collapsed lung. The challenge has been described online since 2001, and increased in popularity in 2007, peaking abruptly in January 2012 and falling off almost as sharply through the first half of that year, then tapering off almost to its previous level by 2014.

Tide Pod Challenge
Like most detergent products, Tide Pods, a laundry detergent pod sold by Procter & Gamble (P&G) since 2012, can be deadly if ingested. Media reports have discussed how children and those with dementia could mistake laundry pods for candy and endanger their health or life by consuming them, and they were named an emerging health risk by the Centers for Disease Control and Prevention in 2012. Between 2012 and 2013, poison control centers reported over 7,000 cases of young children eating laundry pods, and ingestion of laundry pods produced by P&G had resulted in six deaths by 2017. In response to the dangers, P&G changed Tide Pod containers to an opaque design, introduced warning labels, and added a bitter-tasting chemical to the pod contents. In late December 2017, Tide Pods emerged within Internet meme culture. In early 2018, their presence in Internet memes led to the "Tide Pod Challenge", which involved a dare to intentionally consume the pods. Responding to the growing med ...
