- Pyloric stenosis (HP:0002021): Pyloric stenosis, also known as infantile hypertrophic pyloric stenosis, is an uncommon condition in infants characterized by abnormal thickening of the pylorus muscles in the stomach leading to gastric outlet obstruction. Clinically infants are well at birth. Then, at 3 to 6 weeks of age, the infants present with projectile vomiting, potentially leading to dehydration and weight loss. Evidence: PCS. Frequency: 1/1. (PMID:22052856)
- Flexion contracture (HP:0001371): A flexion contracture is a bent (flexed) joint that cannot be straightened actively or passively.

According to the WHO criteria, osteoporosis is defined as a BMD that lies 2.5 standard deviations or more below the average value for young healthy adults (a T-score below -2.5 SD). Evidence: PCS. Frequency: 1/1. (PMID:22052856)

Large fontanelles are diagnosed if the fontanelles are larger than age-dependent norms. Evidence: PCS. Frequency: 1/1. (PMID:22052856)
