Article Abstract
Purpose: The aim of this study was to determine the influence of H2RAs to the 24-h I-131 uptake in the thyroid gland.
Material And Methods: A prospective study with quasi-experimental pre- and post-study design was done. Subjects with normal fT4 level who fulfilled the inclusion criteria were selected. All subjects received 0.2 mCi of I-131 orally, and the thyroid uptake calculations were performed at 24 h later. The same procedure was performed 4 weeks later. All of the subjects were asked to consume H2RAs 1 h before the administration of I-131 of the second procedure. Both 24-h thyroid uptakes were statistically analysed.
Results: A total of 14 subjects were enrolled in this study. Most of them were women (78%) with an average age of 37.6 years old (range: 20-55). This study showed a median of 24-h thyroid uptake of I-131 before and after H2-receptor antagonist of 20.6% (range: 11.1-57.8%) and 16.7% (range: 8.1-39.4%) respectively.
Conclusion: H2-receptor antagonist caused a significance reduction of 24-h I-131 uptake value in the thyroid gland.

Famotidine (FMD) is an H₂-receptor antagonist with limited oral bioavailability and a short plasma half-life (2.5-4 h). Silk fibroin-chitosan nanoparticles (FBN-CS-NPs) represent a novel nanocarrier approach for treating peptic ulcers, combining biocompatibility, mucoadhesiveness, and pH-sensitive release.

Kawasaki disease (KD) is an acute systemic vasculitis managed mainly through intravenous immunoglobulin (IVIG), aspirin, and steroids. Although gastrointestinal symptoms are common, gastrointestinal bleeding is rare. We present the case of an 11-month-old girl with incomplete KD who developed severe gastrointestinal bleeding due to multiple gastric ulcers, despite prophylactic H2-receptor antagonist therapy, requiring blood transfusion therapy.

Background: The association between proton pump inhibitors (PPIs) and stroke remains controversial, while H receptor antagonists (HRAs) have been less studied in relation to stroke. This study aimed to explore the relationship between PPIs, HRAs, and overall acid-suppressant medications with stroke using data from the National Health and Nutrition Examination Survey (NHANES) 1999-2018.
Methods: Data on acid-suppressant use were obtained from the NHANES prescription medication survey for the past month, classifying individuals using PPIs or H2RAs as acid-suppressant users.

Gastroesophageal reflux disease (GERD) is a common condition in infants, causing vomiting, irritability, and feeding difficulties. Though typically mild and self-limiting, severe cases may result in complications such as esophagitis, failure to thrive, or recurrent aspiration pneumonia. This review highlights a tiered approach to management, emphasizing non-pharmacological methods such as feeding adjustments, and thickened feeds as first-line treatments.
