These lesions appear and evolve in a very similar manner. These inflammatory skin conditions are among the top ten common consults in a physician’s clinic. • Lesions most commonly start on the face (Figure 1); often spare the ‘napkin area’ • When the child begins to crawl, the extensor surfaces of the knees can be involved • Chronic, fluctuating course, varying with factors such as teething, infections, emotional upset and climate changes Common Features of Eczematous Dermatitis (ED) Childhood Phase 1. ACUTE STAGE: The primary clinical presentation of acute ED begins with an itchy edematous and red patch which then develops fluid-filled vesicles which may later coalesce to become larger bullae. When these vesicles or bullae erupt and become eroded, they become more pruritic with occasional pain and edema. • Lesions commonly involve the elbow (Figure 2) and knee flexures (Figure 3), the sides of the neck, the wrists and the ankles • Hand involvement is sometimes associated with nail changes (pitting and ridging) • Acute vesiculation should always suggest the possibility of bacterial or viral infection. 2. SUBACUTE STAGE: Almost immediately, secondary changes develop. The fluid filled vesicles or blisters turn into a wet crust, then into a dry scab, resulting in a dry, scaly patch. Adult phase 3. CHRONIC STAGE: The inevitable scratching and excoriations of the itchy patch lead to varying degrees of infection which further lead to thickening or lichenification, and post-inflammatory hyperpigmentation or hypopigmentation of the involved skin. The series of primary and secondary changes re-occur at the initial patch, or spread to other areas depending on the continued activity or presence of the primary cause in subacute ED. CAUSES B. COMMON TYPES OF ECZEMA Classification of eczema is largely empirical, and in most circumstances, the diagnosis is based only on clinical findings. There are many types of eczema recognized clinically and are discussed below. 1. Atopic Dermatitis 2. Contact Dermatitis 3. Dyshidrotic Dermatitis 4. Nummular Dermatitis 5. Asteatotic Dermatitis 6. Stasis Dermatitis • Similar to the childhood phase, although erythroderma is more common • Multifactorial • 70% have family history • Related to mutations in fillagrin (FLG) gene • Positive food allergy tests are common in children with AD, but skin prick testing and RASTs poorly predict actual food reactions in patients. DIAGNOSIS • Seldom aided by investigations • Serum IgE, specific radioallergosorbent tests (RASTs) and prick tests usually only confirm the atopic diathesis • 20% of individuals with atopic dermatitis have normal IgE levels and negative results on RASTs • Bacteriology to identify bacterial infection and potential antibiotic resistance • Viral swab if herpes simplex infection (eczema herpeticum, Figure 4) is suspected. • Patch-testing is particularly useful in adults to identify contact allergens responsible for deterioration of atopic dermatitis. I. ATOPIC DERMATITIS DEFINITION • Chronic inflammatory skin disease that usually occurs in persons with a personal or family history of other atopic conditions, such as asthma and allergic rhinitis. • Lifetime prevalence is 10–20% in children and 1–3% in adults • Prevalence has increased two- to three-fold over the last 30 years in industrialized countries • A family history of atopic disease remains the strongest predictor for the development of AD 132 Figure 1. Infantile AD with facial involvement Eczema nocturnal itching, but can cause drowsiness the next morning. • Non-sedating antihistamines have limited effectiveness for pruritus in AD. SECOND-LINE TREATMENT 1. Topical immunomodulators (tacrolimus and pime­ crolimus) • Approved for intermittent use in mild-to-moderate disease in patients aged 2 years or above. • Useful for maintenance therapy after establishing acute control of disease flares with topical corticoste­ roids. • Especially helpful in head and neck dermatitis where steroid use should be limited. 2. Phototherapy (UVB) or photochemotherapy (psoralen UVA) • Beneficial in adult atopic dermatitis that is unres­ ponsive to topical treatment or so widespread that topical treatment is impractical. • Broadband UVA and UVB, narrowband UVB, combination UVAB, oral and bath psoralen plus ultraviolet A (PUVA), and UVA1 have all shown clinical safety and efficacy in the treatment of AD. Figures 2 & 3. Childhood AD with involvement of the flexural areas SPECIAL CONSIDERATIONS FOR THERAPY OF ATOPIC DERMATITIS FIRST-LINE TREATMENT 1. Reduction of trigger factors – atopic dermatitis can be aggravated by various trigger factors. • Environmental Control • Contact allergy: consider this if exacerbation of previously controlled eczema or patient reacts to topical treatments. • Infection: both bacterial (Staphylococcus aureus and Streptococcus) and viral (herpes simplex) can worsen eczema. • House dust mites: reduction of exposure by regular cleaning of the home by means of vacuuming and damp dusting may be helpful. Animal dander also can aggravate atopic dermatitis. 2. Bathing and emollients • Most patients have dry skin and avoidance of detergents is important. • Soap substitutes and emollients can improve skin hydration and barrier function. 3. Topical corticosteroids • Principal treatment for the inflammation and pruritus of atopic dermatitis • Less potent topical corticosteroids should be used on the eyelids, face and flexural areas • Shorter periods of medium-potency topical corticosteroid use are as effective as a longer course of low-potency corticosteroids in controlling AD flares. Maintenance therapy follows once disease has been stabilized. 4. Antihistamines • Sedating antihistamines are useful in patients with THIRD-LINE TREATMENT 1. Systemic corticosteroids – although oral corticoste­ roids are effective for acute exacerbations of dermatitis, they are seldom used as continuous treatment. 2. Systemic immunosuppressant therapy • Reserved for severe, recalcitrant cases • Before starting therapy, the long-term side effects should be discussed. • Cyclosporin is most studied; an intermittent, 12-week course of cyclosporine at dose levels of 5 mg/kg has been shown to be effective. Side effects include: hypertension and renal toxicity. • Azathioprine is effective in severe atopic dermatitis, but has a slow onset of action (usually 4–6 weeks) and can cause bone marrow suppression. PROGNOSIS • Although there is currently no cure for atopic dermatitis, various interventions can control symptoms. The condition can be expected to clear in 60–70% of children by their early teens, although relapses may occur. • The mainstay of preventive therapy is avoidance of skin irritation and dryness. Adults with atopic dermatitis are advised to avoid occupations such as car mechanic, hairdresser and nurse. OTHER SUPPLEMENTAL THERAPIES • There is no definitive evidence that routine diet restrict­ ion or allergen avoidance has a role in the treatment of AD except in cases where acute clinically relevant reactions have occurred. • Studies regarding breastfeeding as a primary prevent­ ive measure in AD have not shown a consistent protect­ ive effect. • Breastfeeding during the first 4 months has a protective effect when compared with cow’s milk, but on its own does not constitute an effective prevention strategy. • The preventive effects of probiotics on AD may appear Learn to access drug info on your cellphone. Send PPD to 2600 for Globe/Smart/Sun users. 133 Eczema to extend beyond infancy although further studies needed. • Preliminary studies of massage therapy, hypnotherapy, and biofeedback have been encouraging. II. CONTACT DERMATITIS CLINICAL FEATURES • Altered state of skin reactivity induced by exposure to an external agent. • 2 TYPES: 1. ALLERGIC -Immunologic: Represents a delayed (type IV) hyper­sensitivity reaction to the over 3700 allergens reported -Exogenous chemicals that have been described to provoke this reaction 2. IRRITANT -Non-immunologic: Based on the irritability of the skin and amount of the contactant -Direct tissue damage results from contact with irritants • Airborne CD due to contactants affect exposed areas, spare covered areas; with involvement of eyelids, inner arms creases of the neck. • Clothing-related allergens affect covered areas especially posterior aspect of neck, upper back, lateral thorax, flexor surfaces, axilla (Figures 4 & 5) • Complete healing may take 4 weeks, with a good prognosis • Topical treatment • indicated for mild cases of contact dermatitis • Systemic treatment • Indicated for control of itching even in cases of limited extent. • Also indicated for moderate to severe acute and/or chronic contact dermatitis. Figure 4. Dermatitic plaque in the peri-umbilical area due to nickel allergy CAUSES • COMMON CONTACT ALLERGENS: o METALS: chrome, nickel o PERFUME INGREDIENTS o RUBBER CHEMICALS o DYES: formaldehyde • STRONG CONTACT IRRITANTS: o ETHYLENE OXIDE o HYDROFLUORIC ACID o WET CEMENT • MILD TO MODERATE CONTACT IRRITANTS: o Soaps, solvents, detergents, fiberglass, metalworking fluids, bleaches, grease removers, insecticides, fertilizers, rodenticides, waxes, polishers DIAGNOSIS 1. Patch testing - standardized diagnostic procedure of choice for contact dermatitis 2. Skin Biopsy: dermal infiltrate with marked eosinophilia 3. In vitro lymphocyte stimulation tests, migration inhibition factor, and other laboratory tests of lymphokine production remain investigational tools that at present are insufficiently standardized to allow clinical application. TREATMENT • Identify contactant by history or by patch testing • Observe for prompt improvement when contactant is discontinued, slow or no improvement when another cross-reacting product is still used. • Use barrier creams including petrolatum jelly when exposure to contact allergen cannot be avoided, or use cotton gloves under plastic gloves, not rubber gloves • Irritants: forceful and prolonged irrigation with water 134 Figure 5. Erythematous scaly plaque in the neck area due to necklace III. NUMMULAR DERMATITIS CLINICAL FEATURES • Also known as discoid eczema; a chronic disorder of unknown etiology • Acquired and multifactorial; rare in children • Some worsen in summer, exacerbated by heat and humidity • Single, multiple or episodic, and recurrent at previously affected sites • Start out as papules and papulovesicles coalescing to form well-demarcated, coin-shaped plaques with pinpoint oozing, crusting, and scale (Figure 6) • Plaques range from 1 to 3 cm in size • Pruritus varies from minimal to severe • Most common sites of involvement are upper extremities, including the dorsal hands in women, and the lower extremities in men CAUSES The following may cause flare-ups: • Wool • Topical medicines: topical steroids • Drugs: gold, methyldopa, streptomycin, aminosalicylic acid, INH Eczema DIAGNOSIS COMMON CONTACTANTS: 1. Serum immunoglobulin E levels are normal 2. Skin Biopsy a. Acute: spongiosis, with or without spongiotic microvesicles. b. Subacute: parakeratosis, scale-crust, epidermal hyperplasia, and spongiosis with mixed cell infiltrates c. Chronic: may resemble lichen simplex chronicus - Nickel, chrome, PPDA, fragrance, balsams - Neomycin - Poison oak or ivy related to mango, lacquer tree oil for furniture, cashew nut shells - Implanted metals - Secondary to distant focus of infections which clear when primary is treated: • Fungal: dermatophytid • Bacterial: bacterid 3. Patch testing • may be useful in chronic recalcitrant cases to rule out a superimposed contact dermatitis TREATMENT • Topical steroids in the mid- to high potency range are the mainstay of treatment • Topical calcineurin inhibitors, tacrolimus and pimecrolimus, and tar preparations are also effective • Emollients can be added adjunctively if there is accompanying xerosis. • Phototherapy with broad or narrow band ultraviolet B may be beneficial • Trial of suspected allergen withdrawal and/or challenge • Treatment of suspected or identified infection: bacterial or fungal • Improve ambient humidity • Avoid skin-drying conditions like overuse of air-conditioning and contact with water (e.g., water compresses) • Oral antihistamines are useful if pruritus is severe DIAGNOSIS 1. Elevated serum IgE demonstrates atopic background 2. KOH/fungal culture of skin scrapings to rule out fungal infection 3. Giemsa staining to rule out viral infection 4. Gram stain and bacterial culture if bacterial super­ infection is suspected 5. Skin Biopsy: Eczematous Dermatitis with mild eosino­ philia TREATMENT • Does not respond well to treatment • Intact, large blisters can be drained, but should not be unroofed • Avoidance of commonly encountered allergens, such as foods and plants, and irritants (e.g., soaps, solvents, acids, and alkalis, can be helpful • Treatment of suspected or identified infection: bacterial or fungal • Use of pure cotton gloves for dry work, plastic or rubber glove on top of cotton gloves for wet work • For maintenance, frequent use of emollients helps to preserve normal skin barrier function Figure 6. Nummular Eczema. Coin-shaped plaques on the arms IV. DYSHIDROTIC DERMATITIS (a.k.a. pompholyx) CLINICAL FEATURES Figure 7. Tapioca-like vesicular eruption on lateral surface of fingers • Acute and/or chronic dermatitis clinically characterized by small vesicles to large blisters on the sides of fingers with or without palms or soles • Discomfort and itching usually precede the development of the blisters, which have been described as having a “tapioca” appearance (Figures 7 & 8) • Blisters may coalesce then desiccate and resolve without rupture • Affects adolescents and young adults • Secondary infections common CAUSES Can be endogenous (intrinsic) or exogenous (due to contactants) Figure 8.

ASTEATOTIC DERMATITIS CLINICAL FEATURES • Acquired dermatitis super imposed on xerosis usually found in the elderly during cold seasons • Manifests as dry, fissured skin with fine scale • Primarily on the extensor aspects of the limbs and trunk • May be extremely pruritic CAUSES OF XEROSIS - Aging - Post-inflammatory change - Post-use of irritants - Low ambient humidity from seasonal change of weather, prolonged airline flights, air-conditioning - Frequent bathing using soaps with high or alkaline pH - Diminished use of emollients - Familial tendency for dry skin Occasionally a presenting sign of hypothyroidism, lymphoma, other systemic diseases DIAGNOSIS 1. Usually clinical diagnosis 2. Skin Biopsy: Hyperkeratosis with a thin granular layer similar to Ichtyosis 3. Thyroid function tests 4. Organs check-up as indicated by history and physical examination • Venous thrombosis from pelvic/lower abdominal ­operations, prolonged recumbency, leg injuries, varicose veins, thrombophlebitis • Multiple pregnancies • Heredity for incompetent valves, causing backflow of blood • Common in wheelchair bound patients • All other situations with decreased muscle pump function for assisting blood return DIAGNOSIS 1. Venous Ultrasonography to rule out deep venous thrombosis (DVT) in cases with acute onset 2. Skin Biopsy shows dilated capillaries with thick walls, abundant melanin and hemosiderin pigment deposition TREATMENT • Weight reduction • Minimize trauma especially from excoriations • Decrease venous hypertension - Use of support hose for prevention of varicosities in those with family history for varicosities • Avoid irritants and contactants including antibiotic, stabilizer and steroid ingredients in topical medications TREATMENT • Responds to application of medium-potency topical steroid ointments and/or liberal application of emollients. • Use emollients liberally, frequently and massage well into moistened skin • Correct hyperthyroidism medically • Correct environment to increase humidity in regards to use of air conditioning/fans. • Wrap with flexible plastic overnight to increase moisture content of skin • Diminish use of soaps V. STASIS DERMATITIS CLINICAL FEATURES • Acquired, due to chronic venous insufficiency • Characterized by erythema, scaling, oozing, crusting and pigmentary changes • Often with pruritus and eczematous changes from scratching and topical medicines used • Typically occurs in the medial supramalleolar region where microangiopathy is most intense • Lesions may lichenify or ulcerate over time (Figure 9) CAUSES OF POOR VENOUS DRAINAGE • Obesity • Trauma 136 Figure 9. Hyperpigmented scaly plaque with ulceration. B.GENERAL GUIDELINES FOR TREATMENT OF ECZEMAS I. TOPICAL A.STEROIDAL PREPARATIONS •Anti-inflammatory medications •Ointments (oil-based) are more effective than creams, although creams and lotions (waterbased, not alcoholic) are useful when the skin is inflamed. •Use topical steroids according to strength and class (See Table 1). •Cutaneous complications such as striae, atrophy, and telangiectasia limit the long-term use of these agents.

SYSTEMIC A. ANTIHISTAMINES •Bedtime: sedating antihistamines e.g., Hydroxy­zine or Benadryl •Daytime: non-sedating antihistamine e.g., Cetirizine, Loratadine •Role of antihistamines in controlling itching in eczema remains to be defined •For patients with significant sleep disruption due to itch, allergic dermatographism, or allergic rhinoconjunctivitis, sedating antihistamines may be useful. B. ANTIBIOTICS •Oral antibacterials or antifungals if infected; or, to reduce bacterial or fungal population of dermatitic skin •Oral anti-viral medications when viral infections occur •Without signs of infection, oral antibiotics general­ly have a minimal therapeutic effect on the dermatitis C. INTRALESIONAL STEROID •Employed to rapidly thin down thick dry patches D. IMMUNOMODULATORY DRUGS •Systemic corticosteroids are known to be effect­ ive in the short-term treatment of eczemas, but no evidence exists to support their use, and rebound flaring and long-term side effects are limiting. •Cyclosporine is effective in the treatment of severe AD, but its usefulness may be limited by side effects. •Conflicting data exist about the efficacy of azathio­ prine, mycophenolate mofetil, and intravenous immunoglobulin (IVIg). III. PHOTOTHERAPY • To suppress the immune system and decrease skin hyper-reactivity • UVA, PUVA, UVB (Broad band or narrow band) NON-MEDICAL TREATMENT I. EMOLLIENTS • Emollients are the first line treatment for atopic ­eczema, having a steroid sparing effect and helping to restore epidermal barrier function. II. OTHERS • Acute Exudative lesions: i. Oil baths ii. Soaks with NSS, Burrows Solution (1:20 dilution) 15 – 30 mins twice a day iii. If infected – 1. potassium permanganate 1:25,000 – 1:50,000 dilution 2. benzalkonium chloride 1:5,000 aqueous solution (may cause contact dermatitis) 3. 5% acetic acid aqueous solution especially for Pseudomonas infection • Subacute: Antipruritic soothing lotions: Calamine lotion (8% zinc oxide/8% calamine); Witch Hazel Solution; Camphor 1% - 3%; Coal tar solution 3% - 10% , Menthol 0.25% - 2.00%; Phenol 0.5% - 1.5%; Salicylic acid 1.0 – 2.0% • Chronic dry thickened lesions: Soak affected areas 5 min in water. Immediately apply a hydrophilic ointment (petrolatum) liberally, massage into the skin thoroughly. • Occlusion using a thin flexible plastic enhances penetration of medications.
