Dermatology Timmins - A skin rash is defined as a change of the skin which affects its texture, color or appearance. Rashes could be localized in one part of the body or they could affect the entire skin. Typically, rashes can cause the skin to itch, become dry, bumpy, blistered, cracked, painful, swollen or warm. usually, rashes could cause the skin to change color. The treatments and causes for rashes vary considerably depending on the diagnosis. The diagnosis is formed by considering a variety of elements like for example what the person's job is, the rashes' overall appearance, family history, what the person may have been exposed to and different symptoms. The diagnosis could in fact confirm any number of health issues.
Having a rash appear anywhere on the body may indicate connected symptoms and signs that are common of specific diseases. Like for instance, the rash in measles is referred to as an erythematous, morbilliform, maculopapular rash. This typically presents itself a couple of days after the fever starts and naturally it presents at the head and after that works its way downwards.
The most common causes of a skin rash comprise anxieties, food allergies, dyes, medicines and insect stings and bites. Jewelry made of nickels and zincs have been found to be allergens. Skin contact with an irritant usually causes hives. These raised portions of skin can become inflamed, itchy, red, swollen and painful. Rashes can even result from a reaction to vaccination, from a fungal infection like for instance ringworm, from friction because of chafing of the skin, from heat exposure or sunburn, and from skin diseases like for example acne or eczema.
Viral and bacterial infections can cause a rash on the skin. The chickenpox, smallpox, cold sore and measles viruses can cause distinct and uncomfortable rashes. There are some uncommon causes of rashes like: Lyme disease, pregnancy, lead poisoning, autoimmune disorders such as psoriasis and of course frequent and repeated scratching on a particular area.
There are lots of probable causes of a rash, making the evaluation more difficult. To be able to acquire an accurate evaluation, a health provider may need to do a completely thorough history. For example, what is the person's job? Are they taking any kind of medication regularly? Has the individual just traveled to whatever exotic locations? Normally, a complete physical examination would be helpful so as to determine the cause and origin of the rash.
Specific Elements to Include in the Examination Are:
The appearance of the rash, like for instance, is it sandpaper and fine as found with scarlet fever, is it purpuric, which is usual for meningococcal disease and vasculitis? Does the rash consist of circular lesions with a central depression, that is typical of molluscum contagiosum and small pox? Or is the rash consisting of plaques with silver scales that is often seen with psoriasis?
How is the rash distributed on the body? With chickenpox, for instance, the vesicles would follow the hollows of the body. They are hence more prominent in the hollows of both shoulder blades as well as on the depression of the spine on the back. The rash presented with scarlet fever becomes confluent and forms bright red lines in the skin creases of the armpits, groins and neck. These lines are known as Pastia's lines. There are not many rashes which affect the soles of the feet or the palms of the hands, although this can be seen in rikettsia or spotted fever, secondary syphilis, hand, foot and mouth disease as well as guttate psoriasis and also in kertoderma blenorrhagica. The symmetry of the rash is another feature to consider. For example, herpes zoster often just affects one side of the body through an outbreak and does not cross the midline.
Usually, it is good advice not to scratch the rash. This is due to the scratching causing a spread of the rash. It could be tempting to softly rub the affected area in order to provide temporary relief but it is better to avoid contact with the affected parts completely.
