Pediatric Nutrition — MCQs

Q: Flaky paint appearance of the skin is seen in

Kwashiorkor. ***Kwashiorkor*** - The **flaky paint appearance** of the skin is a classic sign of Kwashiorkor, resulting from widespread **dermatitis**, skin peeling, and hyperpigmentation/desquamation. - This symptom is due to severe **protein deficiency**, leading to impaired tissue repair and skin integrity. *Dermatitis* - This is a general term for **skin inflammation** and can have various causes, but it does not specifically describe the "flaky paint" appearance in the context of malnutrition. - While Kwashiorkor involves dermatitis, simply stating "dermatitis" is not as specific as the named condition. *Pellagra* - Characterized by the "3 D's": **dermatitis**, diarrhea, and dementia, caused by **niacin (vitamin B3) deficiency**. - The dermatitis in pellagra typically presents as a symmetric, pigmented rash in sun-exposed areas, often described as a **"Casal's necklace"** or glove-like distribution, not "flaky paint." *Marasmus* - Involves severe **overall calorie and protein deficiency**, leading to extreme thinness and a **wasted appearance**. - While skin changes can occur, the characteristic "flaky paint" dermatosis with skin peeling and edema is more typical of Kwashiorkor, which has a predominant protein deficiency.

Q: Deficit in weight for height in a 3-year-old child indicates a type of malnutrition:

Acute malnutrition. ***Acute malnutrition*** - A deficit in **weight for height** is a key indicator of **acute malnutrition**, often referred to as **wasting**. - This condition reflects a recent and often rapid loss of weight, indicating insufficient nutritional intake or severe disease over a short period. *Chronic malnutrition* - **Chronic malnutrition** is characterized by a deficit in **height for age**, indicating **stunting**. - This reflects prolonged undernutrition, leading to impaired growth over a longer duration. *Concomitant acute and chronic* - This describes a situation where both **weight for height** (wasting) and **height for age** (stunting) are deficient. - While possible, a deficit in **weight for height** *specifically* refers to acute malnutrition, even if chronic malnutrition is also present. *Underweight* - **Underweight** refers to a deficit in **weight for age**, which can be caused by either **acute** or **chronic malnutrition**, or both. - It is a more general term and does not specifically differentiate between the acute or chronic nature of the malnutrition as precisely as weight-for-height or height-for-age.

Q: A 2-year-old child presents with severe acute malnutrition with features of kwashiorkor. Which of the following clinical signs is most indicative of this condition?

Edema. ***Edema*** - The presence of **bilateral pitting edema**, particularly in the feet and legs, is the **hallmark sign of kwashiorkor**, a form of severe acute malnutrition (SAM). - Edema is a **critical diagnostic criterion** for kwashiorkor and distinguishes it from marasmus (the other major form of SAM which presents with severe wasting without edema). - According to **WHO criteria**, bilateral pitting edema in the presence of malnutrition is diagnostic of kwashiorkor-type SAM. *Hyperpigmentation* - While skin changes including **hyperpigmentation** can occur in kwashiorkor, they are not the most specific or consistent diagnostic feature. - Hyperpigmentation may be seen in various nutritional deficiencies and dermatological conditions, making it less definitive than edema for diagnosis. *Alopecia* - **Hair changes** (sparse, thin, easily pluckable hair with flag sign) can occur in kwashiorkor as part of protein-energy malnutrition. - However, alopecia is not as specific or diagnostic as bilateral pitting edema, which is the defining clinical feature of kwashiorkor. *Scaly dermatitis* - **Dermatosis** with desquamating skin lesions (flaky paint dermatosis) can be seen in kwashiorkor, often in areas of friction. - While supportive of the diagnosis, scaly dermatitis is less specific than edema and can occur in various nutritional deficiencies including zinc deficiency and pellagra.
