A young child has been admitted with a diagnosis of enterobiasis (pinworm infection). This child will most likely have a history of:

Choice A reason: Perianal itching is the hallmark symptom of enterobiasis, caused by pinworms laying eggs at night, irritating the skin. This aligns with pediatric infectious disease evidence, making it the most likely history in a child admitted with pinworm infection, accurately reflecting the condition’s presentation. Choice B reason: Malnutrition is not typically associated with pinworms, which cause localized irritation rather than systemic nutrient loss. Perianal itching is the primary symptom, making this incorrect, as it does not reflect the usual clinical history of a child with enterobiasis in a hospital setting. Choice C reason: Bedwetting is unrelated to pinworm infection, which primarily causes perianal itching due to nocturnal egg-laying. Itching is the expected history, making this incorrect, as bedwetting does not correlate with the typical presentation of enterobiasis in a young admitted child. Choice D reason: Restlessness may occur due to itching but is less specific than perianal itching, the defining symptom of pinworms. Itching directly ties to the diagnosis, making this less precise and incorrect compared to the primary history expected in a child with enterobiasis infection.
