Q

Q: What rare syndrome is associated with GERD and an abnormal posture?

A

A: Sandifer syndrome

17
Q

How does Sandifer syndrome respond to treatment?

A

A: It responds to acid suppression.

18
Q

How is benign GER typically diagnosed in infants?

A

A: Through history and examination alone.

19
Q

Name a condition associated with GERD and dental issues.

A

A: Dental erosion

20
Q

What is the typical length range of the LES in adults?

A

A: 3-6 cm.

21
Q

What happens to the LES location and length during the first year of life?

A

A: It lengthens and moves inferiorly

22
Q

What is a significant risk factor for GERD in children?

A

A: Large volume feeds causing gastric distention.

23
Q

Q: What is secondary GERD?

A

A: GERD that arises due to other underlying conditions.

24
Q

Q: How often do infants by age 4 months experience GER symptoms?

A

A: Two-thirds of infants experience GER symptoms.

25
Q

Q: What can be a physical complication of GER that characterizes GERD?

A

A: Esophageal stricturing

26
Q

Name one rare complication of pediatric GERD.
A:

A

Barrett’s esophagus

27
Q

Q: What symptom is commonly seen in Sandifer syndrome?

A

A: Opisthotonus positioning (arched back).

28
Q

Which diagnostic group recommends the definition of GER as the passage of gastric contents into the esophagus?
A:

A

NASPGHAN (North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition).

29
Q

Q: What role does esophageal clearance play in GERD?

A

A: It helps reduce esophagitis by clearing refluxed content

30
Q

Q: What is the main difference in the LES between infants and adults?

A

A: In infants, the LES is shorter and located higher.

31
Q

Q: What is the significance of mucosal defense in GER?

A

A: It protects the esophagus from acid damage.

32
Q

Q: Why might certain drugs exacerbate GERD symptoms?

A

A: They can increase LES relaxation.

33
Q

What is Zollinger-Ellison syndrome, and what is its primary symptom?
