What is Seborrheic Dermatitis?

Seborrheic dermatitis, otherwise known as seborrheic eczema is a common inflammatory skin disorder characterized by scaly, flaky, itchy red skin and persistent dandruff patterned especially on sebum-gland rich areas.

Seborrheic dermatitis is thought to be due to the contribution of yeast Malassezia, to the abnormal immune response. The yeast hydrolyzes sebum and releases toxic substances that cause skin irritation and inflammation.

Other causes include environmental changes, stress, genetics, Vitamin A, pyridoxine and riboflavin deficiencies, medications, hormonal imbalance, and abnormal immune response.

The clinical manifestations come out steadily, with dandruff as the usual first sign. It may occur on the scalp, face and on areas where skin folds, with areas becoming red, itchy and flaky.

Seborrheic dermatitis in infants is termed as cradle cap. It is not dangerous and is just a temporary condition. It comes out as thick, crusty, yellow scales over the infant’s scalp. When it happens in infants, the disorder will resolve itself within days and without any treatment.

Once you get this skin condition, it is likely to become persistent and there are no measures to stop it permanently. But there are a number of treatment options to control the symptoms. Applying medicated creams and lotions to the affected body areas is the mainstay measure. Topical corticosteroid is only for short-term use because of rebound effect which may promote dependence. Frequent shampooing ang longer periods of lathering can reduce dandruff.

What is Dermatitis Herpetiformis?

Dermatitis Herpetiformis, otherwise known as Duhring’s disease, is a chronic autoimmune blistering dermatological condition characterized by clustered excoriations, urticaria and vesicles located on the elbows, knees, back and buttocks. As the name suggests, the inflammation is similar to herpes, but it is not related to herpes virus. It was Dr. Louis Duhring who originally described the disease in the year 1884 at the University of Pennsylvania.

The papulovesicular eruptions are intensely itchy and chronic distributed symmetrically on extensor surfaces. This condition also involves the appearance of a rash. The rash results when gluten joins with IgA, both enter the bloodstream and circulates in the system and finally, gluten and IgA clog up the small blood vessels in the skin. This will draw neutrophils and release chemicals which really produce the rash. At first, the person will notice a slight pigmentation at the site where the lesions come out. Then later it will become vesicles that occur in groups.

Dermatitis herpetiformis responds well to Dapsone. For most patients, this drug is an effective treatment that will improve the disease in just a few days. It responds so quickly that itching is significantly reduced in two to three days. However, when the damage has reached the gastrointestinal tract, this pharmacological treatment has no effect.

To help control the disease, a strict gluten-free diet should be observed as lifetime management. This modification can radically decrease related intestinal damage and other complications.

What is Tick bite?

In the United States alone, ticks are considered to be the primary vectors of human diseases. The concern here is not the bite itself but the toxins and microorganisms present in the tick’s saliva transmitted via tick bites.

Ticks are arthropods that feed on the blood of warm-blooded animals. Painlessly, they excavate into the skin with their feeding part, bite, withdraw blood and finally drop off after they become swollen as they are filled with blood.

There are roughly 800 species but only two families of ticks, namely Ixodidae and Argasidae, are identified to spread infections to humans. Ixodidae or the hard ticks possess a tough back plate that defines their appearance. They are likely to attach and feed for hours to several days. On the other hand, Argasidae or the soft ticks have rounded bodies and do not possess a hard back plate. They feed only for less than an hour.

In almost all cases of tick bites, the area bitten by ticks develops usually painless, red rashes. Usually, there is a formation of classic bull’s eye on the skin surface. Classifying theses rashes is a significant problem as it is very similar to skin infection and inflammation. Later, the bite site develops burning, itching and hardly ever, a localized intense pain is experienced. Some individuals may develop shortness of breath and paralysis.

When a tick is spotted in the body, remove it right away to avoid a skin reaction and decrease the odds of getting infected. With a pair of curved forceps, snatch the head of the tick held as near to the skin and pull it straight up. Never squeeze the tick. Pull the head of the tick gently away from the skin until the tick lets go. Put it in a container with a tight-fitting lid for examination. Clean the area of the bite with a rubbing alcohol and afterwards, wash hands with soap and water.

People living in regions where the risk of getting Lyme disease is relatively high, a single dose of doxycycline can prevent the disease if taken in 3 days of a tick bite.

To help decrease pain, itching and inflammation, ice application for about 15 to 20 minutes every hour for as long as necessary is recommended. Doctors may suggest antibiotics, antihistamines, local anesthetics, skin protectants such as calamine and topical corticosteroids.

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.

Eczema Pictures

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 Seborrheic Keratosis?

Known also as Seborrheic verruca and senile wart, Seborrheic Keratosis is a noncancerous growth of idiopathic origin and is the most common benign tumor in older population.

The wart may just be single or may come in clusters of dozens and its size ranges from being tiny to larger than 1 inch in diameter. Usually, they come out as white to light tan and darken to brown or black as time goes by. At first, they are flat but as they grow thicker over time, they rise above the skin surface giving rise to a dome-shaped appearance. The characteristic feature of this skin condition is the waxy, stuck-on appearance, but their texture may become dry, rough and bumpy. When they start appearing on the face, they may become unsightly. This is asymptomatic. However, they can tingle, swell and hemorrhage easily.

The primary cause of Seborrheic Keratosis is yet undecided. Commonly affected are the sun-exposed areas such as the back, arms, face and neck, so perhaps, prolonged exposure to ultraviolet rays may play a role. The second factor is genetics. Some families have innate predisposition to have these multiple lesions.

After proper diagnosis, no treatment is necessary except in cases where it becomes irritated or unattractive. Remember also that there is no way to prevent new dark spots from forming. Picking at the lesion will just cause a small risk of a localized infection. If the tumor becomes terribly itchy or is irritated by clothing, a mild topical steroid cream can be used. Also, it can be removed by cryosurgery or freezing. If the lesion is small, it can be treated with light electrocautery while larger lesions can be removed by electrodessication and curettage, shave biopsy, or cryotherapy with liquid nitrogen. Except in patients with dark complexion, when properly performed, the removal of seborrheic keratoses will not cause much noticeable scarring.

What is Folliculitis?

It is a common dermatological condition characterized by the appearance of numerous small red or pink lesions with accompanying red halo indicating inflammation in one or more hair follicles. The pus-filled, red lesions cause the skin to appear like a chicken skin. Any part of the skin can be affected; ten to one hundred small bumps may come out in the chest, back, scalp, underarms, groin, extremities, face and buttocks. Mild to moderate folliculitis may often involve itchiness. In more severe cases where the infection is deeper and affects the entire follicle, the problem is pain. Scratching off the top exposes a small locked in hair within.

When hair follicles are damaged by tension from uncomfortable clothing, follicular blockage or shaving, folliculitis begins. In the majority of cases, the damaged follicles become infected with Staphylococcus aureus.

On the whole, it may be cosmetically disturbing but it medically undisruptive. The prognosis is very good as it is an easily curable condition. Most cases may resolve suddenly without undergoing any medical treatment.

To prevent folliculitis, use the following self-care guidelines. Shave in the same direction of hair growth using electric razor and avoid trimming the irritated areas. Avoid tight, constrictive clothing. Washing personal items such as linens and towels frequently is important.

An effective measure to promote drainage of the infected follicles is the application of hot, moist compresses. Depending on the result of the bacterial culture, the physician may endorse the use of antibacterial wash and antibiotic pills. Antibiotics can be applied directly to the skin or taken per orem to control infection To prevent further damage to the hair follicles and infection avoid shaving the area but if it becomes necessary, use a clean, new razor blade or an electric razor each time.

What is Basal Cell Carcinoma?

The most common type of skin cancer is the basal cell carcinoma. It is a type of non-melanocytic skin cancer that takes place from basal cells and accounts for approximately 75% of all skin cancer cases. Metastasis and mortality are rare, yet, it can bring considerable damage and disfigurement by invading proximate tissues of the eyes, ears or nose. Fair-skinned people with a family history of thus cancer are mainly affected.

Two thirds of the cases involves sunlight exposure as a significant factor, which confirms why tumors develop typically on sun-exposed areas such as the face, scalp, neck, torso, back, and legs. Exposure to sunlight leads to the formation of thymine dimmers which is DNA damage. Another risk factor is exposure to ultraviolet waves in tanning booths.

A basal cell carcinoma may appear at first as a little, shiny, semi-transparent dome-shaped tumor with rolled margins frequently covered by small, superficial blood vessels termed as telangiectases. Some basal cell carcinomas include melanin pigment causing a brown pigmentation. The open sore may bleed and heal again and again.

To make an accurate diagnosis, a shave biopsy is performed. A sample of the affected skin is taken out and is viewed under magnification to verify presence of cancer cells.

The modes of treatment adjust conditional on the size, level of penetration, and location of the basal cell tumor. Excision takes the cancer out. In curettage and electrodessication, the tumor is scraped away and electricity destroys any remaining cancerous cells. If the cancer has metastasized to organs or lymph nodes or in such cases when surgery cannot treat the cancer, radiation is desirable. If the basal cell carcinoma is under the superficial type, then topical creams with Imiquimod or 5-fluorouracil may be prescribed by the physician.

Ringworm Pictures

What is Ringworm?

Ringworm or Dermatophytosis is a very common skin disease caused by several different fungal infections collectively known as tinea. The term ringworm originates from the early belief that the disease was caused by a parasitic worm which is untrue. The lifetime risk of an individual to develop this superficial fungal disease is between 20 to 30%.

Ringworm Symptoms

  • The infection causes flaking, ring-shaped, itchy red patches that develop on various parts that could erupt and ooze. The patches often have sharply-defined borders growing to nearly one inch crossways. They are frequently redder around the outside with clear tone in the middle. This forms the manifestation of a ring wherein the infection remains active.
  • There are hairless patches and scales on the scalp, and scratchy, scaling irritation under a beard.
  • Nails thicken, become discolored, crusty and rough and could even crumble.
  • There is dry scaling and fissuring of the skin between the toes.
  • The groin is a usual area of infection. Usually on the inner area of the upper thigh, scaly, red-brown patches develop.

Ringworm Causes

Naturally, bacteria and fungi live on our bodies. A number of these microorganisms are helpful while others are opportunistic, multiply in haste to form contagious diseases. When a specific fungus thrives and multiplies anywhere, ringworm arises. The mode of transmission is via direct skin-to-skin contact, and contact with inanimate, personal objects. Exposure to infected animals is one mode of transmission. In very uncommon cases, infection can be attributed to exposure to infected soil. If the soil does have ample nutrients, the fungus that causes ringworm in humans can survive for an extended period of time. Still, for a person to become infected in this mode, the individual would have to have prolonged contact with harshly contaminated soil or else the odds are thin.

Ringworm Treatment

Individuals with ringworm respond well to self-care treatment. They are advised to keep their affected skin as clean and dry as possible. If it starts to erupt, apply damp compress to clear out the area. Use OTC antifungal powders, creams and lotions especially those containing ketoconazole, clotrimazole, terbinafine and miconazole. These are generally used once or twice a day. Infection begins to disappear within a week. With continued application for the recommended amount of time will guarantee the total eradication of the fungal infection.

When there is a severe or persistent infection and OTC treatments fail, it may require treatment by a physician. Antifungal oral agents may be given.

If there is ring worm on the groin, the individual should wear cotton underwear and change it more than once per day. If there is athlete’s foot, change the socks frequently to keep the feet dry.
