What are Cold Sores?

Medically known as orolabial herpes, fever blisters or cold sores are tiny, painful, erythematous-based clusters of grouped vesicles that come out on the lips that are caused by a herpes simplex virus (HSV-1). The herpes simplex virus can easily penetrate the body via cracks in the skin around the mouth. The virus can be transmitted through sharing of eating utensils, kissing and touching the affected individual’s saliva.

A premonitory symptom of a tingling and burning pain heralds the appearance of the fluid-filled blisters by up to a day. They are typically limited to the mouth area, but they can still occur on the nose, chin and cheeks. After the sores emerge, they typically burst open leading to a clear fluid leakage. After it becomes dry, it crust over and fades away after two weeks at most. Some individuals may carry the herpes virus but they don’t get the condition.

Prevention is the best way to keep away from getting the viral infection. Avoid sharing eating utensils, drinking cups or any other personal items to any person. Avoid being exposed to body fluids of an infected individual.

Orolabial herpes usually heal on their own just within several days. Be cautious not to use topical creams with steroids as they exacerbate manifestations. There are more than a few medications available that can reduce the period or symptoms of fever blisters. Treatment options include topical Acyclovir creams, ointments and other prescription-strength topical antiviral medications.

What are Bed sores?

Bed sores, also identified as pressure ulcers or decubitus ulcers, are confined area of tissue death that are likely to progress when soft tissue is compressed between a bony prominence and an outside surface for an extended period of time. This kind of skin ulceration is mostly observed in patients who are bedridden and those who are improperly positioned in bed.

Because of the compression, blood flow to that area is radically reduced which causes blanching. The common compensatory response of the body when there is absent or reduced blood flow is vasodilation, so if the pressure is removed, the skin area takes on a brighter color or what we call reactive hyperemia. If the area blanches with fingertip pressure or if redness on the area fades away within 1 hour, tissue damage is negative. But if after one hour and there is still redness, then tissue damage exists. Other warning signs are discolored and swollen skin especially above the bony prominences and signs of infection.

In combination with pressure, there are few other forces which contribute to the formation of decubitus ulcers, such as shearing and friction. Shearing, which accounts for a high frequency of sacral bed sores, is the force applied against the skin surface when a patient is moved or repositioned in bed, by log rolling, pulling, pushing in bed. This action results in the straightening and tearing of small blood vessels, leading to a reduction of blood flow and later, necrosis. The second factor is friction. When two objects move across one another, for instance, when a client is pulled up in bed, the skin is rubbed against the bed sheet. This factor can eliminate the superficial layers of the skin, making it at risk to ulceration.

To prevent skin breakdown, it is essential to maintain proper skin care. The skin should be assessed once a day, paying particular attention to surfaces of bony prominences. The area must be kept clean and dry and free from irritation by urine, sweat, feces and others. The sacral area can be applied with a moisture-barrier cream. Massaging the bony prominences must be avoided since it will cause further deep tissue damage. If the tissue is already necrotic, it is an absolute must to get rid of it by debridement since necrotic or dead tissue is an perfect region for bacterial growth and has the capacity to seriously compromise healing of wound.
