If a toddler presents with unilateral issues and discharge, what should be suspected?

• A. Allergic reaction
• B. Sinus infection
• C. Foreign body
• D. Viral infection

Answer: (C)

In a toddler presenting with unilateral issues and discharge, the suspicion of a foreign body is particularly significant. This is primarily due to the behavior and developmental stage of toddlers, who are naturally curious and often put small objects in their noses or ears.

Unilateral discharge, especially if it is accompanied by signs of irritation or discomfort, strongly points towards the presence of an object lodged in one side. Common symptoms include unilateral nasal obstruction, foul-smelling discharge, or even bleeding in cases where the foreign body causes trauma to the mucosa.

In contrast, allergic reactions typically present bilaterally with itchy, watery eyes and nasal discharge that is clear and bilateral, rather than the more localized and often purulent discharge seen with foreign bodies. Sinus infections, although possible, usually exhibit bilateral symptoms along with systemic signs such as fever and headache, and are less common in very young children compared to other causes. Viral infections tend to cause diffuse symptoms involving both sides of the nasal cavities.

Therefore, when assessing unilateral discharge in a toddler, a foreign body must be considered as a likely and urgent diagnosis in order to prevent further complications.
