Differential Diagnosis

• Acid reflux / heartburn
• Appendicitis
• Gastroesophageal Reflux Disease Between the painful episodes, the child may behave relatively normally and be free of pain. As a result, initial presentation can be confused with that of gastroenteritis [45]. As symptoms progress, increasing lethargy often develops, which can be mistaken for meningoencephalitis. Some authors have hypothesized that the lethargy is caused by increased levels of endogenous opioids, suggested by cases with pupillary miosis and reversal with naloxone [46].
