Dermatitis
DERMATITIS, also known as ECZEMA, is a group of diseases that results in inflammation of the skin . These diseases are characterized by itchiness , red skin , and a rash. In cases of short duration there may be small blisters while in long-term cases the skin may become thickened . The area of skin involved can vary from small to the entire body. Dermatitis
Dermatitis
is a group of skin conditions that includes atopic dermatitis , allergic contact dermatitis , irritant contact dermatitis , and stasis dermatitis . The exact cause of dermatitis is often unclear. Cases are believed to often involve a combination of irritation, allergy , and poor venous return . The type of dermatitis is generally determined by the person's history and the location of the rash. For example, irritant dermatitis often occurs on the hands of people who frequently get them wet. Allergic contact dermatitis, however, can occur following brief exposures to substances a person is sensitive to. Treatment of atopic dermatitis is typically with moisturizers and steroid creams. The steroid creams should generally be of mid- to high strength and used for less than two weeks at a time as side effects can occur. Antibiotics may be required if there are signs of skin infection . Contact dermatitis is typically treated by avoiding the allergen or irritant. Antihistamines may help with sleep and to decrease nighttime scratching

Itch
ITCH (also known as PRURITUS) is a sensation that causes the desire or reflex to scratch. Itch has resisted many attempts to classify it as any one type of sensory experience. Modern science has shown that itch has many similarities to pain , and while both are unpleasant sensory experiences, their behavioral response patterns are different. Pain creates a withdrawal reflex, whereas itch leads to a scratch reflex . Unmyelinated nerve fibers for itch and pain both originate in the skin ; however, information for them is conveyed centrally in two distinct systems that both use the same nerve bundle and spinothalamic tract .

Erythema
ERYTHEMA (from the Greek _erythros_, meaning red) is redness of the skin or mucous membranes, caused by hyperemia (increased blood flow) in superficial capillaries. It occurs with any skin injury, infection, or inflammation. Examples of erythema not associated with pathology include nervous blushes. CONTENTS * 1 Causes * 2 Diagnosis * 3 Types * 4 See also * 5 References * 6 External links CAUSESIt can be caused by infection , massage , electrical treatment, acne medication, allergies , exercise, solar radiation (sunburn ), cutaneous radiation syndrome , mercury toxicity, blister agents , niacin administration, or waxing and tweezing of the hairs—any of which can cause the capillaries to dilate, resulting in redness. Erythema is a common side effect of radiotherapy treatment due to patient exposure to ionizing radiation . DIAGNOSIS Erythema disappears on finger pressure (blanching ), while purpura or bleeding in the skin and pigmentation do not. There is no temperature elevation, unless it is associated with the dilation of arteries in the deeper layer of the skin

Complication (medicine)
COMPLICATION, in medicine , is an unfavorable evolution or consequence of a disease , a health condition or a therapy . The disease can become worse in its severity or show a higher number of signs, symptoms or new pathological changes, become widespread throughout the body or affect other organ systems. A new disease may also appear as a complication to a previous existing disease. A medical treatment, such as drugs or surgery may produce adverse effects and/or produce new health problem(s) by itself. Therefore, a complication may be iatrogenic , i.e., literally brought forth by the physician. Medical knowledge about a disease, procedure or treatment usually entails a list of the most common complications, so that they can be foreseen, prevented or recognized more easily and speedily. Depending on the degree of vulnerability, susceptibility, age , health status, immune system condition, etc. complications may arise more easily. Complications affect adversely the prognosis of a disease. Non-invasive and minimally invasive medical procedures usually favor fewer complications in comparison to invasive ones. Disorders that are concomitant but are not caused by the other disorder are comorbidities . This conceptual dividing line is sometimes blurred by the complexity of the causation or the lack of definite information about it

Atopic Dermatitis
ATOPIC DERMATITIS (AD), also known as ATOPIC ECZEMA, is a type of inflammation of the skin (dermatitis ). It results in itchy , red, swollen, and cracked skin. Clear fluid may come from the affected areas, which often thicken over time. The condition typically starts in childhood with changing severity over the years. In children under one year of age much of the body may be affected. As children get older, the back of the knees and front of the elbows are the most common areas affected. In adults the hands and feet are the most commonly affected areas. Scratching worsens symptoms and affected people have an increased risk of skin infections . Many people with atopic dermatitis develop hay fever or asthma . The cause is unknown but believed to involve genetics , immune system dysfunction, environmental exposures, and difficulties with the permeability of the skin. If one identical twin is affected, there is an 85% chance the other also has the condition. Those who live in cities and dry climates are more commonly affected. Exposure to certain chemicals or frequent hand washing makes symptoms worse. While emotional stress may make the symptoms worse it is not a cause. The disorder is not contagious . The diagnosis is typically based on the signs and symptoms. Other diseases that must be excluded before making a diagnosis include contact dermatitis , psoriasis , and seborrheic dermatitis

Allergic Contact Dermatitis
ALLERGIC CONTACT DERMATITIS (ACD) is a form of contact dermatitis that is the manifestation of an allergic response caused by contact with a substance; the other type being irritant contact dermatitis (ICD). Although less common than ICD, ACD is accepted to be the most prevalent form of immunotoxicity found in humans. By its allergic nature, this form of contact dermatitis is a hypersensitive reaction that is atypical within the population. The mechanisms by which these reactions occur are complex, with many levels of fine control. Their immunology centres on the interaction of immunoregulatory cytokines and discrete subpopulations of T lymphocytes. CONTENTS * 1 Signs and symptoms * 2 Cause * 3 Mechanism * 3.1 Memory Response * 4 Diagnosis * 5 Treatment * 6 References SIGNS AND SYMPTOMSThe symptoms of allergic contact dermatitis are very similar to the ones caused by irritant contact dermatitis, which makes the first even harder to diagnose. The first sign of allergic contact dermatitis is the presence of the rash or skin lesion at the site of exposure. Depending on the type of allergen causing it, the rash can ooze, drain or crust and it can become raw, scaled or thickened

Irritant Contact Dermatitis
IRRITANT CONTACT DERMATITIS is a form of contact dermatitis that can be divided into forms caused by chemical irritants and those caused by physical irritants. CONTENTS * 1 Chemical irritant contact dermatitis * 2 Physical irritant contact dermatitis * 2.1 Low humidity * 2.2 Plants * 3 References CHEMICAL IRRITANT CONTACT DERMATITISChemical irritant contact dermatitis is either acute or chronic, which is usually associated with strong and weak irritants respectively. The following definition is provided by Mathias and Maibach (1978): The mechanism of action varies. Detergents, surfactants, extremes of pH, and organic solvents all directly affecting the barrier properties of the epidermis. These effects include removing fat emulsion, defatting of dermal lipids, inflicting cellular damage on the epithelium, and increasing the transepidermal water loss by damaging the horny layer water-binding mechanisms and damaging the DNA, which causes the layer to thin. Concentrated irritants have an acute effect, but this is not as common as the accumulative, chronic effect of irritants whose deleterious effects build up with subsequent doses (ESCD 2006). Chemical irritants are often strong alkalis as found in drain cleaners and soap with lye residues. Many other chemical compounds can also cause contact dermatitiis

Stasis Dermatitis
STASIS DERMATITIS refers to the skin changes that occur in the leg as a result of "stasis" or blood pooling from insufficient venous return; the alternative name of VARICOSE ECZEMA comes from a common cause of this being varicose veins . Insufficient venous return results in increased pressure in the capillaries with the result that both fluid and cells may "leak" out of the capillaries. This results in red cells breaking down, with iron containing hemosiderin possibly contributing to the pathology of this entity. CONTENTS * 1 Symptoms * 2 Treatment * 3 See also * 4 References SYMPTOMS * The skin appears thin, brown and tissue-like, with possible skin lesions (macule or patches), red spots, superficial skin irritation and/or darkening and/or thickening of the skin at the ankles or legs * The skin may be weakened and may ulcerate in areas * Legs, ankles, or other areas may become swollen * Open sores, ulcers * Itching and/or leg pains * Sometimes pain may persist from swollen tissues and may feel like "stabbing" or "needle pricks"The cracks and poor skin-condition of this disorder predisposes for the entry of bacterial infection causing spreading cellulitis infection in the leg. If the skin condition deteriorates further and breaks down, a venous ulcer (also known as a stasis ulcer) may form

Diagnostic Method
MEDICAL DIAGNOSIS (abbreviated DX or DS) is the process of determining which disease or condition explains a person's symptoms and signs . It is most often referred to as DIAGNOSIS with the medical context being implicit. The information required for diagnosis is typically collected from a history and physical examination of the person seeking medical care. Often, one or more DIAGNOSTIC PROCEDURES, such as diagnostic tests , are also done during the process. Sometimes Posthumous diagnosis is considered a kind of medical diagnosis. Diagnosis
Diagnosis
is often challenging, because many signs and symptoms are nonspecific . For example, redness of the skin (erythema ), by itself, is a sign of many disorders and thus doesn't tell the healthcare professional what is wrong. Thus differential diagnosis , in which several possible explanations are compared and contrasted, must be performed. This involves the correlation of various pieces of information followed by the recognition and differentiation of patterns. Occasionally the process is made easy by a sign or symptom (or a group of several) that is pathognomonic . Diagnosis

is a major component of the procedure of a doctor\'s visit . From the point of view of statistics , the diagnostic procedure involves classification tests

Differential Diagnosis
In medicine , a DIFFERENTIAL DIAGNOSIS is the distinguishing of a particular disease or condition from others that present similar clinical features. Differential diagnostic procedures are used by physicians and other trained medical professionals to diagnose the specific disease in a patient , or, at least, to eliminate any imminently life-threatening conditions. Often, each individual option of a possible disease is called a differential diagnosis (for example, bronchitis could be a differential diagnosis in the evaluation of a cough that ends up with a final diagnosis of common cold ). More generally, a DIFFERENTIAL DIAGNOSTIC PROCEDURE is a systematic diagnostic method used to identify the presence of a disease entity where multiple alternatives are possible. This method is essentially a process of elimination or at least a process of obtaining information that shrinks the "probabilities" of candidate conditions to negligible levels, by using evidence such as symptoms, patient history, and medical knowledge to adjust epistemic confidences in the mind of the diagnostician (or, for computerized or computer-assisted diagnosis, the software of the system). Differential diagnosis can be regarded as implementing aspects of the hypothetico-deductive method , in the sense that the potential presence of candidate diseases or conditions can be viewed as hypotheses that physicians further determine as being true or false

Scabies
SCABIES, previously known as the SEVEN-YEAR ITCH, is a contagious skin infestation by the mite Sarcoptes scabiei . The most common symptoms are severe itchiness and a pimple -like rash. Occasionally, tiny burrows may be seen in the skin. Once infected, a never-before-infected person will usually develop symptoms in between two and six weeks. If a person has a second exposure later in life, the body's immune system will often respond much more quickly and symptoms may begin within as little as 24 hours. These symptoms can be present across most of the body or just certain areas such as the wrists, between fingers, or along the waistline. The head may be affected, but this is typically only in young children. The itch is often worse at night. Scratching may cause skin breakdown and an additional bacterial infection of the skin. Scabies
Scabies
is caused by infection with the female mite Sarcoptes scabiei var. hominis . The mites burrow into the skin to live and deposit eggs. The symptoms of scabies are due to an allergic reaction to the mites. Often, only between 10 and 15 mites are involved in an infection. Scabies
Scabies
is most often spread during a relatively long period of direct skin contact with an infected person (at least 10 minutes) such as that which may occur during sex. Spread of disease may occur even if the person has not developed symptoms yet
