What is Acne?

Acne is a skin condition characterized by minor, although infrequently serious, skin eruptions due to inflammation around the sebaceous glands. It is most prominent on the face, chest, arms and back. Roughly about 85% of all people have acne outbreaks in some point in their lives.

Normally, the sebaceous glands produce a fatty, oily substance known as sebum, to protect and lubricate the skin. Acne results when the sebum flow is obstructed by dead skin cells, dried sebum or by bacteria. When there is a complete blockage, whitehead is produced. When the blockage is incomplete, blackhead results. In time, the clogged hair follicle enlarges, producing a bump. The follicles continue to enlarge until the walls rupture, permitting the normal skin bacteria to enter into the deeper layer of the skin. This will result to an inflammation. If the inflammation is close to the surface, this is termed as pustule, pimple for deeper inflammation and much deeper is called cyst.

Remove excess oil by regular gentle washing of the face with non-irritating unscented soaps. However, avoid vigorous washing and scrubbing as these may irritate the skin, making the acne worse. The use of over-the-counter preparations and topical solutions with benzoyl peroxide improves acne. If the acne is severe, dermatologists may prescribe topical and oral antibiotics. If the patient has drug-resistance to antibiotics, Accutane may be used as a substitute. If acne is fully managed, scars can be dealt with resurfacing derma procedure called dermabrasion. Except in severe cases where the skin eruption is widespread, normally acne is undisruptive and responds well to treatment.

What is Psoriasis?

Psoriasis is a common T-cell-mediated autoimmune, persistent skin disorder, characterized by circumscribed patches of raised, thickened, red bumps covered with silvery-white, flaking scales. Naturally in the deepest layer of skin, there are new skin cells continuously being formed. From there, they ascend to the epidermal layer where dead surface cells are shed in a 28-day-process. In areas affected by psoriasis, however, the problem is new cells only need three to four days to reach the epidermal surface, leading to an increased epidermal cell turnover with marked thickening which causes the typical scaly plaques.

In almost all cases, the primary cause is unspecified. It is believed that activated T lymphocytes produce chemical messengers that stimulate abnormal growth of keratinocytes and dermal blood vessels. Other factors may be associated with heredity. Flare-ups may be elicited by infection, skin trauma and injury, stress, certain medications, corticosteroid withdrawal, alcohol and cold temperature and various environmental factors.

There is no known way to prevent psoriasis, and there is no cure either. The primary goal of treatment is to suppress the signs and symptoms of the disease. The treatment regimen depends on the severity of the condition as well as the patient’s age, history, compliance to therapy, and sex.

Exposure to sunlight improves many individuals with the condition. Maintaining the skin soft and well moisturized is effective. Application of heavy moisturizing creams can prevent skin dehydration especially when applied straight away after bathing. Never use irritating cosmetics and soaps. Do no scratching or skin rubbing or any aggressive action which can cause bleeding and irritation. Bath soaks with coal tar can eliminate and trim down the plaques. A physician-directed light therapy may be necessary.

The three fundamental modes of treatments for psoriasis are topical therapy, phototherapy and systemic therapy; all these therapies may well be used unaccompanied or in combination. Under topical therapy, the major remedies are corticosteroids, vitamin D-3 derivatives, coal tar and retinoids. In cases where psoriasis is extensive, as characterized by more itchy patches than can simply be counted, then UV-B light and PUVA are used. The third treatment mode is systemic therapy which includes drugs that are usually established after both topical treatment and light therapy have become unsuccessful.

What is Shingles?

Herpes zoster, also known as shingles is a highly contagious disease attributable to the reactivation of the dormant human herpes virus type 3 virus situated in the dorsal nerve root ganglion of the spinal nerves. The virus can migrate along the path of a nerve to the skin surface causing a rash of painful blisters. This disorder affects only those who once have had chicken pox and commonly hits over age 50. In a client with a history of chickenpox, shingles can occur at some immunocompromised situations. Prognosis is good except when the virus extends to central nervous system.

It is still undefined how and why reactivation happens. It is assumed that the virus reactivates when, as a result of old age, illness, cancer, stress or immunosuppressant medications, the immune system turns out to be too vulnerable to keep the virus in a state of dormancy. After viral reactivation, the chicken pox virus travels down the sensory nerve into the skin to cause shingles.

In early stages, there is a tingling, itching, lightning bolt sensation followed by pain on one side of the body. One to three days after the pain starts, a rash with raised, red lumps and blisters erupts on the skin surface following a dermatomal outline or a ray-like distribution as blisters follow the pathway of individual nerves. They start to become pustules, and then scabs form by 10 days.

Separate the infected person from others because exudates from the lesions hold the virus. Maintain standard precautions. Use an air mattress on the bed and keep the atmosphere cool. Never scratch the skin where the rash is located to avoid the risk of secondary infections and scarring. To soothe the blisters, render cool water compress to suppurating blisters for 20 minutes many times a day. In the early stage of the disease, antiviral drugs may be combined with a strong corticosteroid to speed up healing and diminish the extent of pain. In the most critical situations, blocking agents are given via injection to stop pain signals from reaching the brain.

What is Eczema?

Eczema is a general term used for common inflammatory dermatological conditions. The most constant features of eczema which are associated to significant amounts of histamine on the skin are pruritus and hyperirritability. Because of the alteration in the lipid content, sebaceous gland activity and sweating, too much dryness with consequential itching develops. This leads to crusting, flaking, cracking and bleeding of the skin. In reaction to skin rubbing, instant redness comes out on the skin. Scratching exposes a healing lesion which may increase the rash. Over time, burning cracks become visible.

The common classifications of eczema are atopic eczema, contact dermatitis, xerotic eczema and seborrheic dermatitis. Atopic eczema is an allergic disease with a hereditary element. Contact dermatitis is a cell-mediated skin sensitivity which results from a direct exosure with a chemical or allergen. A very common skin disorder among the older population is xerotic eczema where the skin becomes so dehydrated it turns into eczema. This type of eczema gets worse in dry winter conditions. Seborrheic dermatitis is a skin condition directly related to dandruff. There is dry and oily flaking in the scalp, face and eyebrows.

Eczema can be genetically inherited but still there is no exact cause but a defect of the skin weakens its role as a barrier. Some people have more than one gene defect leading to abnormalities in proteins which are known to be essential in maintaining skin integrity. Some forms of eczema can be triggered by environmental allergens direct contact with irritants, temperature, humidity, and psychological stress.

The course of action for the treatment of eczema includes decreasing irritation and scratching, lubricating the skin and preventing secondary infections. Individuals should stay away from allergenic substances such as harsh soaps and detergents. Scratching the affected area must be avoided since it will just worsen the condition ang may spread the irritation. Keep the fingernails short and clean. To prevent it from being scratched, it is effective to cover the area with clothing or sterile bandage. If exposed to allergenic substances, immediate washing of the exposed area with soap ang running water can remove the irritating chemical. To soothe the skin, intermittently apply wet compresses for short periods. OTC corticosteroid creams and oral antihistamines can help to relieve the intense itching. If secondary bacterial infection develops, antibiotics may well be needed.

What is Tinea Versicolor?

Dermatomycosis furfuracea, also called as Tinea versicolor is a condition distinguished by a rash on the trunk and proximal extremities, majorly caused by Malassezia globosa. This yeast is naturally living on the human skin and only becomes disruptive under special circumstances, including high temperature, weakened immunity, and hormonal abnormalities. It is assumed that the yeast feeds on lipids on top of dead skin cells.

Generally, oval-shaped spots with sharp borders roughly about ¼ to 1 inch in diameter often come into the skin surface together to form a bigger patch. Frequently affected body areas are the back, upper arm, torso, lower legs, armpit, and could also be show on the face. There is an infrequent fine scaling of the skin which gives an external ash-like scale. During a strenuous activity or in warm days, the body temperature is elevated. Sometimes when there is an elevation of the body temperature, pin-prick itching is felt in the affected areas. The warmer the temperature, the worse it gets. The distressing itch stops once sweating begins.

Pigmentary alterations occur. The term versicolor presents the detail that it brings about color shifts to the involved skin by either becoming lighter or darker than the adjacent skin surfaces. Commonly, people who have dark complexion will have hypopigmentation, while those with lighter skin tone will have hyperpigmentation. These temporary discolorations are termed as sun fungus.

For the treatment of tinea versicolor, wash and dry the affected skin area. A thin layer of antifungal agents are applied to the skin two times a day for less than 2 weeks. Some doctors prescribe the most economical yet effective treatment which is selenium sulfide shampoo to be applied for 10-15 minutes before rinsing; done twice a week for about 2 to 4 weeks. In severe, massive and recurring cases, Nizoral pills will eliminate the fungus and relieve any itch.
