DIFFERENT TYPES OF ECZEMA
There are different types of eczema including atopic eczema, contact allergic eczema, discoid eczema, irritant eczema, and varicose eczema. These can be acute (presenting within 6 weeks) or chronic ( more than 6 weeks).
1. Atopic Eczema is common in children and is also related to conditions, such as allergic asthma. Studies show that 6.75% of children in India suffer from atopic eczema. What is more alarming is that the number of affected children has increased tremendously in the last decade. Eczema is troublesome in the way that it causes, lack of sleep, slowing growth, and causing tiredness, and irritability. Atopic eczema presents as a red, itchy, and sometimes weepy rash. In most babies, these rashes start on the face while in older children it appears in the skin folds first including the elbows and knees. It is a chronic condition and sometimes can flare up badly, and may also become infected. Most children find relief from this ski condition with age. However, many of them have to deal with chronic (long-term) atopic eczema.
2. Seborrhoeic Eczema is mainly caused by Malassezia, a naturally occurring yeast on the skin. Malassezia is also the main cause of dandruff. The symptoms of seborrhoeic eczema include redness, scaling, or dandruff on the scalp. However, it is not limited to the scalp, and red, dry, scaly patches may be observed in the skin folds like the sides of the nose, back, chest. Those who have a tendency to develop psoriasis or rosacea are usually at more risk of getting seborrhoeic eczema. Seborrhoeic eczema generally responds very well to treatment with antifungal shampoos and anti-inflammatory skin creams prescribed by dermatologists.
3. Contact Allergic Eczema is caused by an allergic reaction to a chemical that comes in contact with the skin. The most common cause of these allergies is skin’s contact with metals like nickel, fragrant perfumes, and other skin/ hair products, chemical preservatives in cosmetic products, and sometimes medications or topical antibiotics. Sometimes, these allergies can also happen because of the products one has been safely using for long but suddenly develops an allergic reaction and it might remain the same for life. Diagnosis of contact allergic eczema is made by identifying the allergen, history of its use, and physical examination of the affected sites. A patch test (allergic test) may also be suggested by the eczema specialist doctor in Delhi if required.
4. Discoid Eczema is caused by chronic stress and a reaction to staphylococci bacterial antigens commonly seen in adults and typically causes a few well-defined, very itchy, and weepy coin-shaped patches of inflamed skin and generally affect the entire body. It is usually chronic and recurrences can also be experienced.
5. Pompholyx is one of the endogenous eczemas. The root cause of this type of eczema is unknown. However, it has been found that heat or emotional upsets or small amounts of nickel in food can also trigger this condition.
It is an unpleasant form of eczema presenting as recurrent bouts of vesicles or larger blisters that appear on the palms, fingers, and/or the soles of adults lasting a few weeks only to recur at irregular intervals.
6. Asteotic Eczema
This occurs in old age patients who always have had dry skin and a tendency to chap.
Over-washing, low humidity, central heating, use of diuretics, and hypothyroidism can aggravate this type of eczema. It is characterized by red superficial fissures and dry skin. Most commonly it affects the legs of elderly patients.
Sometimes association with malabsorption syndromes, zinc deficiency, or internal malignancy is also observed.
7. Varicose Eczema or gravitational eczema affects the lower legs. It is caused by poor blood circulation and leakiness of some of the valves in the lower leg veins. Ultrasound investigations are required to diagnose the condition and treatments focusing to improve blood circulation are advised.
Most of these eczemas can also present with episodes of remissions and exacerbations and can be associated with aggravating factors.
A proper and thorough workup needs to be done to identify the triggers as they vary from patient to patient. Some eczemas can really impact the quality of life of patients.
