Objective: The objective was to investigate the presence of Helicobacter pylori with polymerase chain reaction in the sinonasal mucosa of patients with or without chronic rhinosinusitis (CRS).
Study Design: A prospective clinical trial.
Methods: Mucosal tissue samples were collected from ethmoid cells of 12 patients with CRS and the removed mucosal part of the middle concha of 13 patients with concha bullosa who were treated surgically in our institution. DNA extracted from these samples was used for the amplification of 16S ribosomal RNA gene of H pylori by nested polymerase chain reaction.
Results: Helicobacter pylori DNA was detected in 4 of 12 patients with CRS, but it was not detected in patients with concha bullosa. Three of four patients with positive results for H pylori had gastroesophageal reflux-related complaints.
Conclusions: It is possible to detect H pylori in the sinus mucosa of some patients with CRS. However, whether H pylori is a causative agent for CRS or a result of CRS is not known.

Background: Adherence of Helicobacter pylori to the surface of the gastric mucosa is the initial and crucial step for its survival and colonization in the harsh conditions of the stomach. We had previously demonstrated that daphnetin has anti-adhesion effect.
Purpose: This study aims to explore the mechanisms of daphnetin to reduce H.

Objective: Globally, over 50% of the population is affected by , yet research on its prevalence and impact in patients with obesity undergoing laparoscopic sleeve gastrectomy (LSG) is inconclusive. This study aimed to assess the prevalence of infection in individuals with obesity undergoing LSG, evaluate the percentage of postoperative staple-line leaks, and explore the potential link between infection and staple-line leaks.
Methods: This retrospective analysis assessed adult patients with class III obesity who underwent LSG between 2015 and 2020 at a tertiary care hospital in Riyadh, Saudi Arabia.
