Jogger's Nipple
Fissure of the nipple, colloquially referred to as "jogger's nipple", is a condition that is the result of chafing of one or both nipples. This can occur in both men and women during physical exercise such as long-distance running where there is prolonged friction between the nipple and clothing. The issue is also commonly seen in surfers who do not wear rash guards or wetsuits. See also * Cracked nipple Cracked nipple (nipple trauma or nipple fissure) is a condition that can occur in breastfeeding women as a result of a number of possible causes.

Petroleum Jelly
Petroleum jelly, petrolatum, white petrolatum, soft paraffin, or multi-hydrocarbon, CAS number 8009-03-8, is a semi-solid mixture of hydrocarbons (with carbon numbers mainly higher than 25), originally promoted as a topical ointment for its healing properties. The Vaseline brand is a well known American brand of petroleum jelly since 1870. After petroleum jelly became a medicine-chest staple, consumers began to use it for cosmetic purposes and for many ailments including toenail fungus, genital rashes (non- STD), nosebleeds, diaper rash, and common colds. Its folkloric medicinal value as a "cure-all" has since been limited by better scientific understanding of appropriate and inappropriate uses. It is recognized by the U.S. Food and Drug Administration (FDA) as an approved over-the-counter (OTC) skin protectant and remains widely used in cosmetic skin care, where it is often loosely referred to as mineral oil. History Marco Polo in 1273 described the oil exportation of B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Disease
A disease is a particular abnormal condition that negatively affects the structure or function of all or part of an organism, and that is not immediately due to any external injury. Diseases are often known to be medical conditions that are associated with specific signs and symptoms. A disease may be caused by external factors such as pathogens or by internal dysfunctions. For example, internal dysfunctions of the immune system can produce a variety of different diseases, including various forms of immunodeficiency, hypersensitivity, allergies and autoimmune disorders. In humans, ''disease'' is often used more broadly to refer to any condition that causes pain, dysfunction, distress, social problems, or death to the person affected, or similar problems for those in contact with the person. In this broader sense, it sometimes includes injuries, disabilities, disorders, syndromes, infections, isolated symptoms, deviant behaviors, and atypical variations of structur ...

Chafing (skin)
Chafing is an irritation of skin caused by friction, moisture or irritating fabric. Prolonged rubbing on the skin may result in skin sting or burn, and development of a mild, red rash; and in severe cases may include swelling, bleeding, or crusting. It often results from body parts that rub against each other or against clothing. It commonly occurs on the inner thighs and buttocks, and nipples, groin, feet, and armpits can also chafe, although there it is less common. Severe chafing is known as friction burn. Causes Repeated rubbing, especially combined with moisture, cause chafing. Chafing may be caused by clothing rubbing against the skin. Chafing can also be caused by improper or overly loose fitting clothing generating extra friction. Wearing a skirt, especially in hot or humid weather, may cause chafing in the upper thighs. Wearing leggings or pants can protect thighs from such rubbing. Ill-fitting clothes can cause chafing; repeatedly rubbing against sleeves, bra straps, ...

Nipple
The nipple is a raised region of tissue on the surface of the breast from which, in females, milk leaves the breast through the lactiferous ducts to feed an infant. The milk can flow through the nipple passively or it can be ejected by smooth muscle contractions that occur along with the ductal system. The nipple is surrounded by the areola, which is often a darker colour than the surrounding skin. A nipple is often called a teat when referring to non-humans. Nipple or teat can also be used to describe the flexible mouthpiece of a baby bottle. In humans, the nipples of both males and females can be stimulated as part of sexual arousal. In many cultures, human female nipples are sexualized, or "regarded as sex objects and evaluated in terms of their physical characteristics and sexiness." Anatomy In mammals, a nipple (also called mammary papilla or teat) is a small projection of skin containing the outlets for 15–20 lactiferous ducts arranged cylindrically around the tip. Ma ...

Surfers
Surfing is a surface water sport in which an individual, a surfer (or two in tandem surfing), uses a board to ride on the forward section, or face, of a moving wave of water, which usually carries the surfer towards the shore. Waves suitable for surfing are primarily found on ocean shores, but can also be found in standing waves in the open ocean, in lakes, in rivers in the form of a tidal bore, or in wave pools. The term ''surfing'' refers to a person riding a wave using a board, regardless of the stance. There are several types of boards. The Moche of Peru would often surf on reed craft, while the native peoples of the Pacific surfed waves on alaia, paipo, and other such water craft. Ancient cultures often surfed on their belly and knees, while the modern-day definition of surfing most often refers to a surfer riding a wave standing on a surfboard; this is also referred to as stand-up surfing. Another prominent form of surfing is body boarding, where a surfer rides the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wetsuit
A wetsuit is a garment worn to provide thermal protection while wet. It is usually made of foamed neoprene, and is worn by surfing, surfers, Underwater diving, divers, windsurfers, canoeists, and others engaged in water sports and other activities in or on water. Its purpose is to provide thermal insulation and protection from abrasion (medical), abrasion, ultraviolet exposure, and stings from marine organisms. It also contributes extra buoyancy. The insulation properties of neoprene foam depend mainly on bubbles of gas enclosed within the material, which reduce its ability to Conduction (heat), conduct heat. The bubbles also give the wetsuit a low density, providing buoyancy in water. Hugh Bradner, a University of California, Berkeley physicist, invented the modern wetsuit in 1952. Wetsuits became available in the mid-1950s and evolved as the relatively fragile foamed neoprene was first backed, and later sandwiched, with thin sheets of tougher material such as nylon or later ...

Cracked Nipple
Cracked nipple (nipple trauma or nipple fissure) is a condition that can occur in breastfeeding women as a result of a number of possible causes. Developing a cracked nipple can result in soreness, dryness or irritation to, or bleeding of, one or both nipples during breastfeeding. The mother with a cracked nipple can have severe nipple pain when the baby is nursing. This severe pain is a disincentive for continued breastfeeding. The crack can appear as a cut across the tip of the nipple and may extend to its base. Cracked nipple develop after the birth of the infant and is managed with pharmacological and nonpharmacological treatment. Signs and symptoms Cracked nipples are classified as a breast disorder. The nipple is not only the structure to deliver milk to the infant, it also contains small, sebaceous glands or Montgomery glands to lubricate the skin of the areola. Cracked nipples are most often associated with breastfeeding and appear as cracks or small lacerations or breaks ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Cutaneous Conditions
Many skin conditions affect the human integumentary system—the organ system covering the entire surface of the body and composed of skin, hair, nails, and related muscle and glands. The major function of this system is as a barrier against the external environment. The skin weighs an average of four kilograms, covers an area of two square metres, and is made of three distinct layers: the epidermis, dermis, and subcutaneous tissue. The two main types of human skin are: glabrous skin, the hairless skin on the palms and soles (also referred to as the "palmoplantar" surfaces), and hair-bearing skin.Burns, Tony; ''et al''. (2006) ''Rook's Textbook of Dermatology CD-ROM''. Wiley-Blackwell. . Within the latter type, the hairs occur in structures called pilosebaceous units, each with hair follicle, sebaceous gland, and associated arrector pili muscle. In the embryo, the epidermis, hair, and glands form from the ectoderm, which is chemically influenced by the underlying mesoderm th ...

Skin Conditions Resulting From Physical Factors
Skin is the layer of usually soft, flexible outer tissue covering the body of a vertebrate animal, with three main functions: protection, regulation, and sensation. Other animal coverings, such as the arthropod exoskeleton, have different developmental origin, structure and chemical composition. The adjective cutaneous means "of the skin" (from Latin ''cutis'' 'skin'). In mammals, the skin is an organ of the integumentary system made up of multiple layers of ectodermal tissue and guards the underlying muscles, bones, ligaments, and internal organs. Skin of a different nature exists in amphibians, reptiles, and birds. Skin (including cutaneous and subcutaneous tissues) plays crucial roles in formation, structure, and function of extraskeletal apparatus such as horns of bovids (e.g., cattle) and rhinos, cervids' antlers, giraffids' ossicones, armadillos' osteoderm, and os penis/os clitoris. All mammals have some hair on their skin, even marine mammals like whales, dolphins, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
