Rome V marks a paradigm shift in pediatric disorders of gut-brain interaction (DGBI). The new Rome V criteria introduced new, updated, and refined definitions for pediatric DGBI. A central feature of this framework is the shift toward anchoring diagnoses more firmly in pathophysiology and anatomic regions rather than age groups. Accordingly, the criteria are now organized into two major categories: upper gastrointestinal DGBI and lower gastrointestinal and biliary DGBI. Several new disorders have been added, including esophageal, feeding, and discomfort disorders, along with additional pain-related conditions. Existing criteria have been further refined, and emerging biomarkers are incorporated to support diagnoses. Finally, there is greater harmony between adult and pediatric diagnoses to support a seamless transition across the age continuum.

Routes of Drug Administration: Parenteral
The intravenous route (IV) of drug administration can be further categorized into two types. The bolus injection administers the entire dose rapidly, while an intravenous infusion slowly delivers smaller doses steadily.
The IV route is often...

Additional Routes of Drug Administration
Administering drugs via inhalation allows for the direct delivery of gaseous, volatile substances or droplets to different parts of the respiratory tract. One of the advantages of the inhalation route is the rapid absorption of drugs into the circulatory system, which is possible because of the large surface area of...

Routes of Drug Administration: Overview
Enteral administration refers to drugs absorbed through the gastrointestinal tract. They can be swallowed (perorally), placed under the tongue (sublingually), or on the inner lining of the cheeks (buccally). Perorally administered drugs take time to be absorbed and have a slower onset of action. The rectal route is another form of enteral administration, which allows for...

Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
