Dermatitis, also known as eczema:
It is a chronic inflammatory skin condition characterized by the appearance of red patches or skin rashes. It affects approximately 20% of children and 10% of adults. It can manifest anywhere on the body, from the head to the soles of the feet
Causes:
Dry skin, exposure to irritants, genetic factors
Symptoms:
- Itching, often accompanied by pain (the most common symptom)
- Severe skin dryness
- Skin peeling and inflammation
- Red patches or pustules, which can be oozing (these symptoms are more severe)
Types:
Firstly: Atopic Dermatitis:
- It is the most common type of eczema, especially in children
- It's a chronic condition, treatable but can recur
- Intense itching, especially at night, is a prominent symptom
- It appears as a skin rash or dry red patches that may bleed when scratched
- Those affected are more prone to developing asthma and various allergies, including seasonal allergies
Secondly: Contact Dermatitis
- This type of eczema occurs due to environmental triggers
- It exhibits the same general symptoms as eczema
- It has three subtypes
Irritant Contact Dermatitis:
- Represents approximately 80% of all cases
- Its main causes include exposure to irritating chemicals
- It manifests as an undefined skin rash at the site of direct exposure
- There is no immune system involvement in this type
Allergic Contact Dermatitis:
- Occurs due to an immune system response to a particular substance
- Causes include:
- Products containing preservatives
- Continuous occupational exposure to allergenic substances such as rubber or latex
Photocontact Dermatitis:
Photocontact dermatitis occurs when a person comes into contact with a substance and sunlight simultaneously. These irritants or allergenic substances are usually external, such as certain sunscreen products, or a result of medication ingestion
Thirdly: Neurodermatitis:
- Appears in the form of one or two patches on the body
- It has a thickened appearance and a rough texture
- Can form anywhere, such as the feet, ankles, hands, and wrists
- Prominent symptoms include nocturnal itching. The more the itching intensifies, the more scratching occurs, leading to skin irritation, inflammation, and worsening of the condition
Fourthly: Dyshidrotic Eczema:
- This type of eczema causes small, itchy blisters on the hands or feet. These blisters may be open and red
- Causes include allergies and moisture on the hands and feet
Fifthly: Nummular Eczema:
- Nummular eczema can occur at any age
- It affects males more than females
- It can affect any part of the body except the face and scalp
- The causes are not clear, but they may include skin irritants, severe skin dryness, insect bites, scratches, and chemical burns
- The patches are coin-shaped on the arms and legs
- The skin around the patches is scaly and inflamed
Treatment for the aforementioned types of eczema:
Topical Moisturizers:
- Topical moisturizers are a fundamental aspect of skin care
- Their use should be continuous, even if the skin appears healthy
- It is recommended to use them 2-3 times a day in generous amounts
Examples include:
Panthenol Domina Cream, a suitable moisturizer for all skin types
LinolaDerm Cream, suitable for severely dry skin
Topical Steroids:
- They are considered the primary treatment for mild to moderate cases
- When used correctly, they are safe and effective
- They help reduce inflammation, itching, and swelling
- Apply a thin layer to the affected areas
- The choice of steroid is based on the severity of the condition and the affected area, as follows:
- Low potency steroids are used on thin-skinned areas, such as the face or neck
- High potency steroids are used on thicker-skinned areas, like the palms, soles of the feet
- Low potency steroids are used for mild cases, while high potency steroids are used for severe cases
To achieve the desired benefit from topical steroids:
- Begin by applying topical moisturizers
- Wait for approximately 30 minutes
- Then apply the topical steroid
Topical Steroids Used in Treating Eczema:
- Hydrocortison Domina cream
- Motasone cream
- Betamethason Domina cream, ointment
- Motasone ointment
- Domivat cream, ointment
Note: The strength of the steroid ranges from weakest to strongest (Hydrocortison Domina being the weakest, and Domivat being the strongest). Treatment typically starts with Hydrocortisone Domina as it is the safest option, considering the method of application for the steroid
Sixthly: Stasis Dermatitis:
- Also known as venous eczema, it's a skin condition that occurs as a result of varicose veins
- Its symptoms are similar to the aforementioned types of eczema
- It is more common in individuals aged 50 and above
- Women are more susceptible to this condition than men
Treatment:
Treatment begins by addressing the cause through the following measures:
- Avoiding prolonged standing and wearing compression stockings to reduce swelling and improve blood flow
- Keeping the feet elevated above heart level for 15 minutes every two hours and during sleep
- Using an appropriate moisturizer to treat dry skin
- If there is pain, redness, or swelling, topical steroids are used
Seventhly: Seborrheic Dermatitis:
- It is considered a chronic inflammatory form of eczema
- It appears in areas rich in sebaceous glands, especially the scalp
- It causes various symptoms ranging from dandruff to skin rashes in the affected area
- Seborrheic dermatitis occurs due to a combination of genetic and environmental factors
- Typically, the trigger is a fungal infection that leads to changes in the skin's nature
- Certain medical conditions, such as psoriasis and acne, can increase the risk of individuals developing seborrheic dermatitis
- It is not contagious
Treatment:
For cases of scaling, options include:
- Salicylic acid
- Topical steroids
Note: Betasalic solution contains both betamethasone and salicylic acid
3. For fungal infections, you can use topical antifungals like Kenazole shampoo
In cases of infants with seborrheic dermatitis, often referred to as "cradle cap," which appears as greasy, scaly patches on the scalp, you can wash the baby's scalp daily with warm water and baby shampoo. However, be cautious with anti-dandruff shampoos, as they may irritate the baby's skin. It's advisable to consult a paediatrician for suitable shampoo options. To remove thick patches, apply oil and gently comb the area with a small hairbrush to help remove the scales
Prevention of Eczema in General:
- Maintain Skin Moisture and Protect from Dryness: Ensure your skin stays moisturized to prevent dryness
- Avoid Sudden Temperature Changes: Sudden temperature changes can trigger eczema flare-ups, so try to maintain a stable environment
- Avoid Contact with Allergenic Substances: Stay away from substances that trigger allergies, such as certain cleaning agents and chemicals
- Maintain Mental Health and Avoid Stress: Taking care of your mental health, reducing stress, and managing anxiety can positively impact your overall well-being and may help in preventing eczema flare-ups
