Objective:
To determine the prevalence of Helicobacter pylori infection in nasal biopsy specimens from patients with chronic rhinosinusitis with polyposis versus control patients, and to assess the correlations between H pylori infection identified in the nasal tissue and patients' sociodemographic data and reflux-related symptoms and signs.
Methods:
Nasal biopsy samples were taken from 75 adult patients who underwent nasal surgery for chronic rhinosinusitis with polyposis (clinical group, n = 45) and a deviated septum (control group, n = 30). H pylori infection was identified using histochemical and rapid urease tests.
Results:
The prevalence of intranasal H pylori infection was significantly higher in the clinical group (28.9 per cent) compared to the control group (3.3 per cent) (p = 0.005). A significant yet weak association was found between positive H pylori status and laryngopharyngeal reflux related hypertrophy of the posterior commissure of the larynx. No other correlations reached statistical significance.
Conclusion:
H pylori infection is potentially related to chronic rhinosinusitis with polyposis. Further research is needed to clarify the role of H pylori as a risk factor for the development of sinonasal diseases and to examine its link with laryngopharyngeal reflux.

Chronic Pharyngitis
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...
Infection
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...
Chronic Pancreatitis I: Introduction
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...
