What type of dermatitis cannot be cured but can be well controlled?

A. Polyuria (frequent urination) is a hallmark symptom of hyperglycemia, not hypoglycemia. It occurs because elevated blood glucose levels exceed the renal threshold, leading to osmotic diuresis and subsequent fluid loss. Children experiencing hypoglycemia do not typically present with increased urination.

B. Dry mucous membranes are a sign of dehydration, which can occur in diabetic ketoacidosis (DKA) or prolonged hyperglycemia due to fluid loss. Hypoglycemia does not cause dehydration; instead, the child may appear clammy and moist due to sweating.

C. Fruity or acetone-smelling breath is associated with DKA, resulting from ketone accumulation due to uncontrolled hyperglycemia. This symptom does not occur in hypoglycemia, which is characterized by low blood glucose without ketone buildup.

D. Diaphoresis (excessive sweating) is a classic sign of hypoglycemia, caused by sympathetic nervous system activation in response to falling blood glucose levels. Additional symptoms include tremors, palpitations, pallor, irritability, hunger, headache, and anxiety. These neurogenic and neuroglycopenic symptoms occur because the brain is highly dependent on glucose, and the body initiates counter-regulatory hormonal responses (epinephrine, glucagon) to raise blood sugar. Recognizing these signs early is critical to prevent severe hypoglycemia, seizures, or loss of consciousness.Top of FormBottom of Form

A. Diaper dermatitis typically affects the diaper area and presents as red, inflamed skin, sometimes with small papules, but it rarely forms moist, weeping blisters over widespread areas or becomes thickened and scaly as seen in chronic eczema.

B. Contact dermatitis occurs after exposure to an irritant or allergen. It usually presents as localized redness, itching, and sometimes vesicles, but it does not typically lead to chronic skin thickening or widespread scaling unless exposure is recurrent and prolonged.

C. Seborrheic dermatitis usually affects areas with high sebaceous gland activity, like the scalp, face, and upper trunk. It presents with greasy, yellowish scales and mild erythema but rarely causes moist, weeping blisters or the thickened, raw skin described in this question.

D. Atopic dermatitis (eczema) is a chronic, relapsing inflammatory skin disorder. It is characterized by red bumps, intense pruritus, and lesions that can form moist, weeping blisters in acute flares. Over time, the skin may become scaly, raw, or lichenified (thickened) due to chronic scratching and inflammation. These features help distinguish atopic dermatitis from other pediatric skin conditions.
