Which of the following is not a feature of infantile colic syndrome
**Core Concept**
Infantile colic syndrome, also known as colic, is a common condition characterized by recurrent episodes of intense crying, abdominal distension, and drawing up of the legs in infants. The pathophysiology is multifactorial, including gastrointestinal, nervous system, and environmental factors.
**Why the Correct Answer is Right**
The features of infantile colic syndrome include intense crying, abdominal distension, drawing up of the legs, and a normal physical examination between episodes. The exact cause of infantile colic is unknown, but it is thought to be related to gastrointestinal immaturity, hypersensitivity to milk proteins, and abnormal gut motility.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect as infantile colic is not typically associated with fever, which is a common feature of infectious or inflammatory conditions.
**Option B:** This option is incorrect as infantile colic is not typically associated with vomiting, which is a common feature of gastrointestinal obstruction or gastroesophageal reflux disease.
**Option C:** This option is incorrect as infantile colic is not typically associated with diarrhea, which is a common feature of gastrointestinal infections or malabsorption.
**Clinical Pearl / High-Yield Fact**
Infantile colic is not a sign of any underlying serious disease, and most children outgrow it by 3-4 months of age. Parents should be reassured that it is a benign condition and not a reflection of poor parenting.
**Correct Answer:** D.
