Dermatology Kitchener - A skin rash is defined as a change of the skin which affects its texture, color or appearance. Rashes could be localized in one area of the body or they can affect the whole skin. Usually, rashes could cause the skin to itch, become bumpy, dry, blistered, cracked, painful, swollen or warm. Normally, rashes can cause the skin to change color. The causes and treatments for rashes differ considerably depending on the diagnosis. The diagnosis is formed by considering different elements like for instance the rashes' overall appearance, what the individual's job is, other signs, family history and what the patient may have been exposed to. The diagnosis may in fact confirm any number of health problems.
The rash may help to indicate some associated symptoms and signs that are common to particular diseases. Measles for instance, can give a rash that is referred to as an erythematous, morbilliform, maculopapular rash. This normally presents itself a couple of days after the fever begins and naturally it presents at the head and then works its way downwards.
The most common causes of a skin rash comprise food allergies, anxieties, dyes, medicines and insect stings and bites. Jewelry made of nickels and zincs have been found to be allergens. Skin contact with an irritant often causes hives. These raised portions of skin could become red, inflamed, itchy, swollen and painful. Rashes may also result from a reaction to vaccination, from a fungal infection such as ringworm, from sunburn or heat exposure, from friction because of chafing of the skin, and from skin diseases like for instance acne or eczema.
Bacterial and viral infections can lead to a rash on the skin. The smallpox, chickenpox, cold sore and measles viruses can result in uncomfortable and distinct rashes. There are some uncommon causes of rashes like for example: Lyme disease, pregnancy, lead poisoning, autoimmune disorders like for instance psoriasis and of course repeated and frequent scratching on a particular area.
There are many probable causes of a rash, making the evaluation harder. To be able to obtain an accurate evaluation, a health provider may have to do a completely thorough history. For example, what is the individual's occupation? Are they taking any kind of medication on a regular basis? Has the person recently traveled to whatever exotic locations? Normally, a complete physical examination will help in order to determine the cause and origin of the rash.
Particular Factors to Include in the Examination Are:
The appearance of the rash, for instance, is it sandpaper and fine as found with scarlet fever, is it purpuric, which is normal for vasculitis and meningococcal disease? Is the rash consisting of plaques with silver scales that is usually seen with psoriasis? Or does the rash consist of circular lesions with a central depression, that is typical of molluscum contagiosum or small pox?
What is the distribution of the rash? For instance with chicken pox, the vesicles often follow the hollows of the body; therefore, they are most prominent along the depression of the spine on the back as well as in the hollows of both shoulder blades. The rash presented with scarlet fever becomes confluent and forms bright red lines in the skin creases of the neck, armpits and groins. These lines are referred to as Pastia's lines. There are not many rashes that affect the soles of the feet or the palms of the hands, although this could be seen in spotted fevers or rikettsia, secondary syphilis, hand, foot and mouth disease as well as guttate psoriasis and even in kertoderma blenorrhagica. The symmetry of the rash is another feature to think about. Like for instance, herpes zoster normally just affects one side of the body during an outbreak and does not cross the midline.
It is generally good advice never to scratch a rash, because whichever scratching may cause it to spread. It could be tempting to softly rub the affected area to be able to provide temporary relief but it is better to avoid contact with the affected parts completely.
