A 14-year-old girl was referred for evaluation of a several-year history of growth failure, chronic abdominal pain, and intermittent emesis. The parents described the child as a "picky eater," and various foods (eg, meat products and beans) frequently caused abdominal distention.

A 4-year-old girl presents with a highly pruritic rash. The day before, she had been playing outdoors at her grandmother's house. No pets were present, and the patient does not recall being stung or bitten by insects. There are bushes on the grandmother's property.

The child has orbital cellulitis, an infection with sometimes serious sequelae that involves the soft tissue of the orbit posterior to the orbital septum. Children are more likely than adults to contract orbital cellulitis; the median age of those affected is 7 years. Preseptal cellulitis--the other major infection of the ocular and adnexal orbital tissue--involves the soft tissue of the eyelids and periocular region anterior to the orbital septum and is considered less severe.

The parents of a 4-year-old girl are concerned because she has experienced hair loss for several weeks. The child is otherwise healthy and active, has no known disorders, and takes no medications.

The mother of this 3-year-old boy noticed that his smile was asymmetric when he awoke that morning. He had been seen 3 days previously for left ear discomfort, sore throat, and a low-grade fever. Otitis media was diagnosed, and amoxicillin was prescribed. The child has an unremarkable history and is otherwise healthy. He has been acting normally and tolerating food and liquids without difficulty.

A 10-year-old girl has had a worsening rash for 1 week. The mildly pruritic, nontender eruption initially appeared on the child's thighs and then spread to the arms and face. The child's right hand, feet, and ankles have been swollen for the past 4 days, which has made ambulation intermittently painful.

Photo Finish: Acute Dx: What Cause of Sudden Illness?

he parents of a 16-year-old girl report that during the past several months, she has exhibited behavioral changes, irritability, increased anger, depression, and anxiety. The girl had previously been healthy, and there has been no recent illness or trauma.

For several days, a 9-year-boy has had painful swelling on the top and left side of his forehead, bilateral eye swelling, intermittent fever, and nasal congestion. He was seen in the office 4 weeks earlier, after he had hit his left eye on a school desk. At that time, he presented with a left retro-orbital headache, nasal congestion and discharge, and intermittent fever.

THE CASE: A 3-year-old boy is brought to the office by his mother. The previous evening, she had noticed a single large red spot on the back of his thigh. This morning, his whole body was covered with a similar rash, and he had a temperature of 38.8°C (102°F). The mother administered 1 dose of acetaminophen at home for the fever; the rash was asymptomatic.
