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 Rosacea?

Rosacea is a very common erythematous, acne-like chronic dermatological condition that affects an estimated 45 million people worldwide.

Still, there is no particular cause that can sufficiently explain the pathogenesis of this disorder. It could be a pattern of genetic predisposition and environmental factors that has caused for it to arise. There is also a link connecting the condition to mites, sun exposure, medications that may cause blood vessel dilation, gastrointestinal diseases and Helicobacter pylori.

The major clinical symptoms of rosacea consist of red patches, development of telangiectases, which are small blood vessels that form just under the skin surface, diffuse facial redness, red cysts, and pink or irritated eyes. These manifestations tend appear, then disappear for weeks, months or even years and then reappear.

It frequently begins with a tendency to go red much more easily than other people do. In time, individuals may see irreversible redness on the face.

Characteristically, the nose can become red and bumpy and develop visible dilated superficial blood vessels. If left untreated, later stages can bring a disfiguring nasal condition called rhinophyma, a condition described by a bulbous, enlarged red nose and puffy cheeks.

Currently, rosacea isn’t regarded as a curable disorder, but it can usually be managed with appropriate, standard treatments. With lasers, intense pulse light, photodynamic therapy and isotretinoin made available, some cases of this condition may be drastically cleared for a long time.
