Itching & rash treatment
Itching is an irritating sensation that has some parallels to pain yet is quite different. Insect bites, exposure plants or foods, skin diseases and skin disorders are examples of the kind of insult which can result in itching. Pruritus may also be caused by systemic diseases (such as obstructive bilary disease) or be of unknown origin. The cutaneous sensation currently referred to as itching may be considered as a uniform response to a wide variety of physical and chemical stimuli, which may be of an endogenous or exogenous nature. Such stimuli act on the receptors of the free nerve endings located at the dermalepidermal junction and around the hair follicles. Scratching is a unique response to the sensation of itching, thought to be a reflex to remove noxious agents from the skin surface. Scratching brings about a transient sense of relief and may even give pleasure (due to morphine receptors). Itching may be a localized or generalized phenomenon. Localized itching includes skin disease like psoriasis or scabies or flea bites, which can all produce pruritus. Generalized pruritus can be the result of certain environmental factors, including an excessively dry or humid climate, dry centralized heating, perspiration, overbathing, and harsh soap. Itching has been known to be accompanied by diseases such as atopic dermatitis, urticaria, allergic rhinitis, allergic conjunctivitis and the like as well as inflammatory responses such as swelling and the like. Moreover, the action accompanied by itching, for example scratching, knocking and the like may worsen the condition of the above-mentioned diseases. Application of a cool, moist washcloth to the area or application of pressure with the palm of the hand near the pruritus area can abate the urge of scratching. Topical preparations may also be used for moisturizing and emollients to fight dryness, but avoiding products with sensitizing potential is vital. Oral medications have been used to treat pruritus, and antihistamines remain the cornerstone of oral therapy. Diaper rash is a common form of irritation and inflammation of those parts of an infant's or adult's body normally covered by a diaper. It frequently occurs also in areas immediately adjacent to the diapered area. This condition is also referred to as diaper dermatitis, napkin dermatitis, napkin rash, and nappy rash. The principal cause of the irritation that characterizes diaper dermatitis or diaper rash is the mixture of urine and stools.
