What disease causes blisters on an eight-month-old baby’s hands?

When the baby is about eight months old, he can basically do some things by himself, and some parents have already weaned their eight-month-old babies. At this time, the baby can also eat some complementary foods by himself without causing parents to worry. However, an eight-month-old baby is still a little too young and may get sick due to insufficient body resistance. So, what is the disease when blisters appear on the hands of eight-month-old babies?

Pediatric eczema, also known as atopic dermatitis (AD), also known as genetic allergic dermatitis and atopic dermatitis, is a chronic, recurrent, inflammatory skin disease. It usually occurs in infancy and continues into childhood and adulthood. The clinical characteristics are eczematous rash, accompanied by severe itching and recurrent attacks. The patients themselves or their families often have obvious "atopy", which seriously affects the quality of life. It is mainly caused by intolerance or allergy to ingested, inhaled or contacted substances. Children with eczema initially develop red skin and rashes, followed by roughness and flaking of the skin. Touching the child's skin feels like touching sandpaper. Heat and humidity can make eczema more obvious.

Causes

The cause and pathogenesis of atopic dermatitis are still unclear. It is currently believed to be related to genetic, environmental, immune, and biological factors. The onset of the disease is mainly due to the combined effects of genetic and environmental factors. Genetic factors play an important role in this regard. Children with a family history of allergies are more likely to develop eczema. The main cause is intolerance or allergy to ingested, inhaled or contacted substances. Environmental factors, especially changes in lifestyle (such as excessive washing, diet, infection, environmental changes, etc.) are important risk factors for the onset of this disease.

Clinical manifestations

The main symptoms are chronic recurrent itching, which affects sleep. It is often characterized by chronic recurrent dermatitis in flexural areas such as the elbows and popliteal fossa. The initial lesions are dense millet-sized papules, papulovesicles or blisters on an erythematous basis. After the blisters rupture, erosive surfaces are formed with serous exudation and crusting. If acute eczema is not treated properly, it may turn into subacute or chronic eczema. If treated promptly and appropriately, it may gradually improve, but it is prone to relapse. In severe cases, large areas of erythema may occur, covered with groups of papules, papulovesicles, blisters, erosions and exudates, with thick crusts on the surface, and may also extend to the entire head and face or head and neck. Erythematous papules, papulovesicles, blisters and pruritus appear around the lesions. Abrasions may cause erosion and scabs, with pus oozing under the scabs, small pustules on the edges, and local lymph nodes enlargement and tenderness. Parallel linear erythema, papules and blisters caused by scratching may also occur in nearby or distant areas.

The course of the disease often evolves gradually through infancy, childhood, and adolescence. A few cases present with onset in a specific age group. In infancy (1 month to 2 years), it is preceded by yellow desquamation of the scalp, and acute erythema, extensive exudation, and induration may appear on the extensor side of the face and limbs. In children (2 to 12 years old), chronic recurrent dermatitis, accompanied by dry skin, is common on the neck, hands, elbows, popliteal fossa, and extensor side of the calves. Skin lesions in adolescents and adults (>12 years old) are similar to those in children, mostly localized dry dermatitis lesions. Due to long-term scratching and friction, lichenification and prurigo-type nodular rash often occur.
