What should I do about my baby's dry eczema?

Babies with dry eczema still need proactive treatment, as dry eczema can cause local skin flaking and itching, leading to extreme discomfort for the child. The primary treatment for dry eczema consists largely of moisturizing; using a baby-specific moisturizing cream applied thickly three to four times a day typically controls most cases of dry eczema effectively. If this approach doesn't manage the condition, under the guidance of a hospital doctor, the use of mild corticosteroid creams can be considered, alongside dietary controls for the child. If the baby is breastfed, the mother should avoid consuming beef, mutton, nuts, and seafood. If the baby is formula-fed, depending on the severity of the eczema, an amino acid-based formula or a hydrolyzed protein formula can be chosen.

How to distinguish eczema from prickly heat

Eczema and heat rash have clear differences, including different causes. Eczema is primarily caused by allergens, as well as excessive mental stress, anxiety, and hormonal imbalances. Heat rash, on the other hand, usually arises from overly humid and hot environments that affect normal sweating function, leading to blocked sweat ducts. Their clinical manifestations also differ. Eczema typically presents as polymorphic and symmetrically distributed lesions, usually manifesting as papules and vesicular papules, and in severe cases, erosion, exudation, and significant itching are observed. Heat rash clinically appears as tiny, pin-sized blisters that emerge in clusters and merge into patches, typically found at skin folds without symmetry. White heat rash generally has less noticeable itching, whereas red heat rash is itchy and can also feel burning.

Symptoms of eczema

Eczema is an intensely itchy skin inflammation reaction caused by various internal and external factors. It is categorized into three phases: acute, subacute, and chronic. 1. Acute eczema: Initially, the skin lesions appear as numerous, densely packed millet-sized papules, vesicopapules, or small vesicles with a reddish base that gradually merge into patches. Due to scratching, the tops of the papules, vesicopapules, or vesicles break open, leading to distinctive punctate exudation and minor erosion with unclear margins. If secondary infection occurs, the inflammation becomes more pronounced, possibly forming pustules, crusts, folliculitis, and boils. There is severe itching. Commonly affected areas include the head, face, behind the ears, extremities, scrotum, and perianal region, often symmetrically distributed. 2. Subacute eczema: Following the reduction of acute eczema inflammation, skin lesions primarily consist of small papules, crusts, and scales, with only a few vesicopapules and erosions, yet intense itching persists. 3. Chronic eczema: Often, chronic eczema results from reoccurring episodes of acute and subacute eczema that do not resolve, or it may start as chronic eczema. Characteristics include thickened, infiltrated skin at the affected sites, which tend to be brownish-red or have pigmentation, a rough surface covered with scales, or crusting caused by scratching. There is severe itching. Common sites include the lower legs, hands, feet, elbows, knees, genitals, and anus. The duration of the disease is variable, it is prone to relapse, and is often long-lasting without resolution.

Is infantile eczema contagious?

Pediatric eczema is a chronic, recurrent inflammatory skin condition that typically presents during infancy and early childhood. Some children may continue to experience symptoms into childhood and even adulthood. It is characterized by skin damage but is not infectious; thus, pediatric eczema is not contagious, which should reassure parents. The causes of pediatric eczema are complex and relate to immune dysfunction or deficiency, and nutritional disorders. External factors also play a role, such as allergies to milk, fish, shrimp, or eggs, as well as mechanical irritation or improper care, all of which can lead to eczema. However, it is not contagious. Poor care can lead to local bacterial infections of the skin, which parents must be careful to avoid.

Can eczema patients eat crab?

People with eczema should not eat crab, as well as mutton, chili peppers, fish, and shrimp. They should also abstain from alcohol, as eczema is an allergic condition and it's difficult to pinpoint specific allergens. Foods like seafood, crab, and chili peppers can potentially trigger a relapse or worsen the symptoms. After the onset of eczema, the affected areas should not be washed with hot water. Instead, antiallergic medications should be used for treatment, such as oral loratadine tablets, and topical application of corticosteroid creams like compound flumethasone ointment. If symptoms persist long-term, it's advisable to visit a dermatology department at a reputable hospital to identify specific allergens and receive targeted treatment. Overall, eczema is a chronic condition that can recur frequently, so attention must be paid to one's diet and lifestyle habits.
