Dermatology Prince George - A rash on the skin is normally defined as a change to the skin in its texture, color or appearance. A skin rash can effect the whole skin or may be localized on one particular area of the body. Rashes can normally cause the skin to itch, become dry, bumpy, blistered, cracked, painful, swollen or warm. Normally, rashes could cause the skin to change color. The causes and treatments for rashes differ considerably depending on the diagnosis. The diagnosis is formed by taking into account various factors like what the individual's occupation is, the rashes' overall appearance, different signs, family history and what the patient may have been exposed to. The diagnosis could in fact confirm whatever number of health problems.
The rash could help to indicate certain connected symptoms and signs which are common to specific diseases. Measles for instance, may give a rash that is called 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 then works its way downwards.
There are several common causes of rashes including: food allergies, anxiety, dyes, medicines and insect stings and bites. The metals zinc and metal are commonly found in jewelry and are commonly known allergens too. Skin contact with an irritant often results in hives. These raised portions of skin can become itchy, red, inflamed, painful and swollen. Rashes can also result from a reaction to vaccination, from a fungal infection like ringworm, from sunburn or heat exposure, from friction due to chafing of the skin, and from skin diseases like for instance eczema or acne.
A skin rash could likewise become present due to a bacterial or viral infection. For instance, the viruses which lead to chickenpox, smallpox, cold sores and measles can be uncomfortable and distinct. There are some uncommon causes of rashes like for example: Lyme disease, pregnancy, lead poisoning, autoimmune disorders like psoriasis and of course repeated and frequent scratching on a specific area.
Because there are a lot of possible causes of a rash, the evaluation may be quite difficult. A health provider may have to do a completely thorough history in order to acquire an accurate evaluation. For instance, what is the patient's occupation? Are they taking any type of medication on a regular basis? Has the patient just traveled to whatever exotic locations? Normally, a complete physical examination would help to determine the cause and origin of the rash.
Particular Factors to Include in the Examination Are:
When referring to the appearance of the rash, is it like for example purpuric, that is usual for vasculitis and maningococcal disease, or is it sandpaper and fine as found with scarlet fever? Does the rash consist of circular lesions with a central depression, which is usual of small pox and molluscum contagiosum? Or is the rash consisting of plaques with silver scales which is often seen with psoriasis?
What is the distribution of the rash? Like for example 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 groins, neck and armpits. These lines are called Pastia's lines. There are not many rashes that affect the soles of the feet or the palms of the hands, however this could 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 normally only affects one side of the body through an outbreak and does not cross the midline.
Generally, it is good advice not to scratch the rash. This is due to the scratching causing a spread of the rash. It can be tempting to gently rub the affected area in order to provide temporary relief but it is better to avoid contact with the affected areas completely.
