What is another name for the acute inflammatory disorder known as miliaria rubra?

1. Heat rash

2. Eczema

3. Psoriasis

4. Contact dermatitis

The correct answer is: Heat rash

Miliaria rubra, commonly referred to as heat rash, is an acute inflammatory disorder that occurs when sweat glands become blocked and sweat is trapped under the skin. This often happens in hot and humid conditions, leading to red, itchy, and sometimes painful bumps on the skin. The term "heat rash" aptly describes this condition as it is closely associated with overheating and excessive sweating. The other options mentioned refer to different skin conditions that do not share the same characteristics or triggers as miliaria rubra. Eczema is a chronic condition characterized by inflamed, itchy skin, psoriasis involves rapid skin cell production leading to scaly patches, and contact dermatitis is a skin reaction caused by exposure to an irritant or allergen. Thus, the distinction between these conditions and miliaria rubra highlights why "heat rash" is the correct term for this specific acute inflammatory reaction.
