Dermatology Penticton - A skin rash is defined as a change of the skin which affects its texture, color or appearance. Rashes can be localized in one part of the body or they may affect the entire skin. Usually, rashes could cause the skin to itch, become dry, bumpy, blistered, cracked, painful, warm or swollen. Often, rashes may 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 such as what the person's occupation is, the rashes' overall appearance, what the patient may have been exposed to, different signs and the family history. The diagnosis can in fact confirm whatever number of health issues.
The rash can help to indicate certain related symptoms and signs which are common to specific diseases. Measles for instance, can give a rash that is known as an erythematous, morbilliform, maculopapular rash. This normally presents itself a few days after the fever begins and classically it presents at the head and afterward works its way downwards.
The most common causes of a skin rash include food allergies, anxieties, dyes, medicines and insect bites and stings. Jewelry made of zincs and nickels have been found to be allergens. Skin contact with an irritant usually leads to hives. These raised portions of skin can become red, inflamed, itchy, painful and swollen. Rashes can also result from a reaction to vaccination, from a fungal infection such as ringworm, from friction because of chafing of the skin, from heat exposure or sunburn, and from skin diseases like for instance acne or eczema.
Viral and bacterial infections can lead to a rash on the skin. The smallpox, chickenpox, cold sore and measles viruses could cause uncomfortable and distinct rashes. There are various uncommon causes of rashes like: lead poisoning, Lyme disease, pregnancy, autoimmune disorders like for instance psoriasis and of course frequent and repeated scratching on a particular part.
There are lots of probable causes of a rash, making the evaluation harder. To be able to get an accurate evaluation, a health provider may have to do a completely thorough history. Like for example, what is the patient's occupation? Are they taking any type of medication on a regular basis? Has the individual just traveled to whatever exotic locations? Often, a complete physical examination would help so as to determine the cause and origin of the rash.
Particular Elements to Include in the Examination Are:
When referring to the appearance of the rash, is it for example purpuric, that is normal for vasculitis and maningococcal disease, or is it sandpaper and fine as found with scarlet fever? 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, which is usual of small pox and molluscum contagiosum?
What is the distribution of the rash? Like for instance with chicken pox, the vesicles normally follow the hollows of the body; thus, 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 which affect the palms of the hands or the soles of the feet, although this can be seen in rikettsia or spotted fever, secondary syphilis, mouth, hand and foot disease as well as guttate psoriasis and likewise in kertoderma blenorrhagica. The symmetry of the rash is another feature to think about. For instance, herpes zoster often only affects one side of the body through an outbreak and does not cross the midline.
It is generally good advice never to scratch a rash, as whichever scratching may cause it to spread. It could be tempting to gently rub the affected area so as to provide temporary relief but it is better to avoid contact with the affected parts completely.
