Zhang Q, Huang H, Li J, Niu Y, Sun P, Cheng F. Knowledge, attitudes and practices of patients with chronic pharyngitis toward laryngopharyngeal reflux in Suzhou, China. BMC Public Health 2023; 23:2542. [PMID: 38115020 PMCID: PMC10731724 DOI: 10.1186/s12889-023-17463-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2023] [Accepted: 12/12/2023] [Indexed: 12/21/2023] Open
Abstract
BACKGROUND This study aimed to investigate the knowledge, attitudes and practices (KAP) of patients with chronic pharyngitis in Suzhou, China toward laryngopharyngeal reflux (LPR). METHODS This cross-sectional study was conducted in patients with chronic pharyngitis in Suzhou, China at the otolaryngology outpatient clinic of the First Affiliated Hospital of Soochow University between November, 2022, and May, 2023. Data was collected through a self-designed online questionnaire encompassing the sociodemographic characteristics and three dimensions of KAP. The questionnaire was administered using SoJump, and data were exported from this platform. Subsequently, statistical analysis, including Structural Equation Modeling, was performed using SPSS 22 software to evaluate the KAP scores. RESULTS A total of 487 valid questionnaires were collected, with 275 (56.35%) female patients. The mean score of KAP were 4.76 ± 2.93 (possible range: 0-11), 33.10 ± 4.46 (possible range: 8-40), 31.29 ± 6.04 (possible range: 8-40), respectively. Pearson's correlation analysis showed significant positive correlations between knowledge and attitude dimensions (r = 0.413, P < 0.001), knowledge and practice dimensions (r = 0.355, P < 0.001), and attitude and practice dimensions (r = 0.481, P < 0.001). Structural equation modeling revealed that education exhibited positive effect on knowledge (β = 0.476, P < 0.001) and attitude (β = 0.600, P < 0.001), and having family history of chronic pharyngitis showed positive effect on knowledge (β = 0.580, P = 0.047), experienced with reflux symptoms showed positive effect on knowledge (β = 0.838, P = 0.001) and attitude (β = 0.631, P = 0.085). Moreover, knowledge showed positive effect on attitude (β = 0.555, P < 0.001) and practice (β = 0.351, P < 0.001). Attitude, in turn, showed positive effect on practice (β = 0.511, P < 0.001). CONCLUSION Patients with chronic pharyngitis had inadequate knowledge, positive attitudes and suboptimal practices toward LPR. Education, family history of chronic pharyngitis, experienced with reflux symptoms might have effect on their KAP.

Abstract
Background Helicobacter pylori is assumed to cause many gastric and extragastric diseases. We aimed to assess the possible association role of H. pylori in Otitis media with effusion (OME), nasal polyps and adenotonsillitis. Patients and Methods A total of 186 patients with various ear, nose and throat diseases were included. The study comprised 78 children with chronic adenotonsillitis, 43 children with nasal polyps and 65 children with OME. OME patients were assigned to two subgroups: those who have and those who did not have adenoid hyperplasia. Among the patients with bilateral nasal polyps, 20 individuals had recurrent nasal polyps and 23 had de novo nasal polyps. Patients who have chronic adenotonsillitis were divided into three groups: those with chronic tonsillitis and those who underwent tonsillitis, those with chronic adenoiditis and adenoidectomy was performed, and those with chronic adenotonsillitis and underwent adenotonsillectomy. In addition to examination of H. pylori antigen in stool samples of all included patients, real-time polymerase chain reaction (RT-PCR) for detection of H. pylori in the effusion fluid was performed, additionally, Giemsa stain was used for detection of H. pylori organism within the tissue samples when available. Results Frequency of H. pylori in effusion fluid was 28.6% in patients with OME and adenoid hyperplasia, while in those with OME it was only 17.4% with a p value of 0.2. Nasal polyp biopsies were positive in 13% patients of denovo, and 30% patients with recurrent nasal polyps, p=0.2. De novo nasal polyps were more prevalent in the positive stools than recurrent ones, p=0.7. All adenoid samples were negative for H. pylori, only two samples of tonsillar tissue (8.3%) were positive for H. pylori, and stool analysis was positive in 23 patients with chronic adenotonsillitis. Conclusion Lack of association between Helicobacter pylori and occurrence of OME, nasal polyposis or recurrent adenotonsillitis.

Low Prevalence of HSV-1 and Helicobacter pylori in HNSCC and Chronic Tonsillitis Patients Compared to Healthy Individuals. Diagnostics (Basel) 2023; 13:diagnostics13101798. [PMID: 37238282 DOI: 10.3390/diagnostics13101798] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2023] [Revised: 05/12/2023] [Accepted: 05/16/2023] [Indexed: 05/28/2023] Open
Abstract
Recent studies identified viral and bacterial factors, including HSV-1 and H. pylori, as possible factors associated with diseases such as chronic tonsillitis and cancers, including head and neck squamous cell carcinoma (HNSCC). We assessed the prevalence of HSV-1/2 and H. pylori in patients with HNSCC, chronic tonsillitis, and healthy individuals using PCR after DNA isolation. Associations were sought between the presence of HSV-1, H. pylori, and clinicopathological and demographic characteristics and stimulant use. HSV-1 and H. pylori were most frequently identified in controls (HSV-1: 12.5% and H. pylori: 6.3%). There were 7 (7.8%) and 8 (8.6%) patients with positive HSV-1 in HNSCC and chronic tonsillitis patients, respectively, while the prevalence of H. pylori was 0/90 (0%) and 3/93 (3.2%), respectively. More cases of HSV-1 were observed in older individuals in the control group. All positive HSV-1 cases in the HNSCC group were associated with advanced tumor stage (T3/T4). The prevalence of HSV-1 and H. pylori was highest in the controls compared to HNSCC and chronic tonsillitis patients, which indicates that the pathogens were not risk factors. However, since all positive HSV-1 cases in the HNSCC group were observed only in patients with advanced tumor stage, we suggested a possible link between HSV-1 and tumor progression. Further follow-up of the study groups is planned.

Abstract
Many studies have described the detection of Helicobacter pylori (HP) in the nasal polyps; however, although gastroesophageal reflux has been associated with chronic rhinosinusitis and nasal polyps development, the role of HP remains unclear. Our aim was to describe the prevalence of HP detection in nasal polyps and its association with gastric HP infection and gastroesophageal reflux dsease (GERD). The prospective study involved 36 patients with nasal polyps, who underwent to endoscopic surgery removal of nasal polyps. Before surgical procedure all patients were tested for gastric HP infection by 13 C-urea breath test, while tissue samples from nasal polyps were tested for HP detection, using rapid urease test (CLO test) and histological examination with Giemsa stain. All patients were asked about GERD-related symptoms. HP in nasal polyps was detected in 9 out of 36 patients (25%) using histological examination with Giemsa stain, while the detection rate of HP was 30.5% (11/36) using CLO test. Furthermore, 28 out of 36 patients (77.7%) had gastric HP infection. All patients with HP colonization in nasal polyps had gastric HP infection and all patients with HP in nasal polyps reported symptoms related to GERD. HP was detected in approximately one out of three patients in nasal polyps, while all patients with HP detection in nasal polyps had concurrently gastric HP infection and reported GERD-related symptoms, suggesting a gastro-nasal route of HP.

Pediatric Laryngopharyngeal Reflux in the Last Decade: What Is New and Where to Next? J Clin Med 2023; 12:jcm12041436. [PMID: 36835970 PMCID: PMC9962831 DOI: 10.3390/jcm12041436] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2022] [Revised: 02/06/2023] [Accepted: 02/07/2023] [Indexed: 02/15/2023] Open
Abstract
BACKGROUND Laryngopharyngeal reflux may affect people of any age; still, most of the accumulated knowledge concerns adults, and evidence regarding pediatric populations remains relatively restricted. This study aims to review the most recent and emerging aspects of pediatric laryngopharyngeal reflux from the last ten years. It also attempts to identify gaps in knowledge and highlight discrepancies that future research should urgently address. METHODS An electronic search of the MEDLINE database was conducted, limited to January 2012 through December 2021. Non-English language articles, case reports, and studies that concerned a purely or predominantly adult population were excluded. The information from the articles with the most relevant contribution was initially categorized by theme and subsequently synthesized into a narrative form. RESULTS 86 articles were included, of which 27 were review articles, eight were surveys, and 51 were original articles. Our review systematically maps the research done in the last decade and provides an updated overview and the current state-of-the-art in this subject. CONCLUSIONS Despite discrepancies and heterogeneity in accumulating research, evidence gathered so far endorses a need for refining an escalating multiparameter diagnostic approach. A step-wise therapeutic plan appears to be the most reasonable management approach, starting with behavioral changes for mild to moderate, uncomplicated cases and escalating to personalized pharmacotherapy options for severe or nonresponsive cases. Surgical options could be considered in the most severe cases when potentially life-threatening symptoms persist despite maximal medical therapy. Over the past decade, the amount of available evidence has been gradually increasing; however, its strength remains low. Several aspects remain markedly under-addressed, and further adequately powered, multicenter, controlled studies with uniformity in diagnostic procedures and criteria are urgently needed.

Abstract
BACKGROUND : Helicobacter pylori is a gram-negative bacteria known as the causative agent of chronic gastritis, peptic ulcer, gastric adenocarcinoma, and gastric mucosa-associated lymphoid tissue lymphoma. Several studies have correlated H. pylori in the pathogenesis of upper airway diseases. H. pylori can be detected in saliva, oropharyngeal aphthae, nasal and sinus mucosa, secretions from the tympanic cavities, larynx, and pharyngeal lymphoid tissue. The diagnosis of LPR can be made simply by examining saliva.
AIM : The aim of the study is to analyze the presence of H.pylori in the saliva of LPR and non LPR patients.
METHODS : This study is an analytic observational study with a case control design. The research was conducted in the ENT-KL Department of Dr. M. Djamil Hospital, Padang, Indonesia. PCR examination was carried out at the Biomedical Laboratory of the Faculty of Medicine, Andalas University on saliva samples to detect the presence of H.Pylori. The study was conducted on 22 LPR patients and 22 control subjects.
RESULT : LPR patients are more common in women than men, which were 12 women and 10 men. The average age of LPR patients is 43.7 years. The presence of H.pylori in LPR patients was 86.4%, while in the non-LPR group was 50%. After being tested using the Chi-square test, a significant difference was found between the presence of H. Pylori and the incidence of LPR (P = 0.010).
CONCLUSION : There was an increase in the frequency of the presence of Helicobacter Pylori in patients with LPR compared to Non LPR patients after statistical analysis.

Abstract
OBJECTIVE To investigate the effect of Helicobacter pylori (HP) eradication therapy on salivary pepsin concentration in laryngopharyngeal reflux (LPR) patients with HP infection. MATERIALS AND METHODS A total of 477 patients with suspected LPR were enrolled from June 2020 to September 2021. Reflux symptom index, reflux finding score, the positive rates and disintegrations per minute values of HP infection detected by 14C urea breath test and salivary pepsin concentrations analyzed using enzyme-linked immunosorbent assay were compared in LPR patients and non-LPR patients with or without HP infection. HP-positive patients were treated with HP eradication therapy while HP-negative patients with PPI therapy. RESULTS The scores of nagging cough (0.88 vs. 0.50, P = 0.035), erythema or hyperemia (1.93 vs. 1.78, P = 0.035) and vocal fold edema (1.04 vs. 0.85, P = 0.025) were higher in the LPR (+) Hp (+) subgroup than in LPR (+) Hp (-) subgroup. The concentrations of salivary pepsin in the Hp (+) subgroup were higher than in the Hp (-) subgroup either in LPR patients (75.24 ng/ml vs. 61.39 ng/ml, P = 0.005) or the non-LPR patients (78.42 ng/ml vs. 48.96 ng/ml, P = 0.024). Compared to baseline (before treatment), scores of nagging cough (0.35 vs. 0.84, P = 0.019) and erythema or hyperemia (1.50 vs. 1.83, P = 0.039) and the concentrations of salivary pepsin (44.35 ng/ml vs. 74.15 ng/ml, P = 0.017) in LPR patients with HP infection decreased after HP treatment; yet, this was not observed for the LPR patients without HP infection treated with PPI only (P > 0.05). CONCLUSION HP infection may aggravate the symptoms and signs of LPR patients, partly by increasing their salivary pepsin concentration.

Abstract
PURPOSE The aim of this study was to investigate the correlation between Helicobacter pylori colonization of tonsillar tissue in chronic tonsillitis and in noninfectious hyperplastic tonsils. MATERIALS AND METHODS All included studies investigated the presence of Helicobacter pylori in tonsillar tissue removed for infectious or noninfectious factors. Included studies must have used an accepted method of testing for Helicobacter pylori. We pooled six eligible studies to perform a traditional meta-analysis. RESULTS Six studies were included, including 462 patients. Helicobacter pylori does have a significant role in chronic tonsillitis compared with noninfectious indications for tonsillectomy for children population. Detection methods had effects on results. CONCLUSION The positive rate of Helicobacter pylori in chronic tonsillitis group was significantly higher than that in simple noninfectious group for the pediatric population, but not for adults. We suspected that chronic tonsillitis is likely to be relevant to Helicobacter pylori.

Abstract
Infection with Helicobacter pylori (Hp) is one of the leading causes of stomach cancer. The ability to treat Hp infection is hampered by a lack of stomach gastric acid environment. This work introduces a nanoliposome that can rapidly adjust the gastric acid environment to ensure a drug's optimal efficacy. We introduce CaCO3@Fe-TP@EggPC nanoliposomes (CTE NLs) that are composed of Fe3+ and tea polyphenols (TPs) forming complexes on the surface of internal CaCO3 and then with lecithin producing a phospholipid bilayer on the polyphenols' outer surface. Through the action of iron-TP chelate, the phospholipid layer can fuse with the bacterial membrane to eliminate Hp. Furthermore, CaCO3 can promptly consume the excessive gastric acid, ensuring an ideal operating environment for the chelate. TPs, on the other hand, can improve the inflammation and gut microbes in the body. The experimental results show that CTE NLs can quickly consume protons in the stomach and reduce the bacterial burden by 1.2 orders of magnitude while reducing the inflammatory factors in the body. The biosafety evaluation revealed that nanoliposomes have good biocompatibility and provide a new strategy for treating Hp infection.

[PMID: 34574466 PMCID: PMC8470705 DOI: 10.3390/ijerph18189545] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/28/2021] [Revised: 09/05/2021] [Accepted: 09/07/2021] [Indexed: 12/18/2022]
Abstract
Objective: Oropharyngeal/laryngeal carcinoma are common cancers of the upper aerodigestive system. Human papillomavirus (HPV) is described as the most frequent in the cancer of unknown primary. The presence of Helicobacter pylori (HP) in the oral cavity is discussed in some papers. The aim of study: To analyze the incidence of HPV and HP in oropharyngeal/laryngeal cancer persons versus persons with chronic tonsillar inflammation and healthy persons. Methods: The samples were taken in three groups: (1) tissue of oropharynx/larynx cancer (103 specimens); (2) tissue of palatine tonsils (85 specimens); and (3) healthy control group (50 specimens). We analyzed the presence of HP (PCR) and HPV genomic DNA (Sacace HPV High-Risk Screen Real-TM Quant) in the samples. Results: HP was detected in 86 samples (83.5%) and high-risk HPV in 62 samples (60.2%). We found a very high incidence of HP. In the cancer group, HP was detected in 82.5% cases and HPV positivity in 57.8%. In total, 7.2% of the cancer patients were negative for HP and HPV together. In turn, 53.6% of the cancer patients were positive for HP and HPV together. Four cases (4.2%) were positive for HPV only. VacA positivity was detected in 82 (79.6%) of the cancer cases and VacA negativity in 21 (20.4%) if the cancer cases. The incidence of HP in chronic inflammation (n = 85) was 65 cases (76.5%) and the incidence of HPV was 38 cases (44.7%). VacA positivity was detected in 59 (69.4%) of the chronic inflammation cases and VacA negativity was found in 26 (30.6%) of the chronic inflammation cases. Regarding the control group, we found HP positivity in 5 cases (11.1%) and HPV positivity in 19 cases (42.2%). There was VacA positivity in 6 cases (50.0%) of the control group. Statistically significantly lower prevalence of HP (p < 0.001) and HPV (p = 0.006) was found in the control group. Conclusions: We suggest that the palatine tonsils are colonized by HP. In our study, HP was present in oropharyngeal cancer in more cases in comparison with HPV infection. The presence of VacA from HP can have an influence on the human epithelial and immune cells’ regulation ways. Our results do not support idea that the CagA-positive HP is a primary carcinogen in oropharyngeal area.

Abstract
The data on association between various pathologies of the ENT organs and gastroesophageal reflux disease (GERD) is analysed in the article. The variety of extraesophageal signs of GERD in children and adults is given, what is advisable to inform physicians of different specialties about the possibilities of antireflux therapy. These options are expanded with the emergence of a unique new drug, Alfasoxx. Its bioadhesive formula is based on hyaluronic acid and chondroitin sulphate thereby protecting the esophageal mucosa. Alfasoxx acts on the surface of the esophageal mucosa without penetrating into the systemic bloodstream and it also has a low allergenic potential, which has been confirmed by numerous studies. With its healing and repairing effect on erosive lesions of the esophageal epithelium, Alfasoxx in combination with proton pump inhibitors is more effective in achieving regression of clinical manifestations of the disease and improving patients quality of life (according to SF-36 questionnaire) compared to proton pump inhibitors monotherapy.

Abstract
Helicobacter pylori (H. pylori) infection has ≈75% probability of causing gastric cancer, so it is considered to be the strongest single risk factor for gastric malignancies. However, the harsh gastric acid environment has created obstacles to medical treatment. This work reports a nanomotor with a bottle-shaped container that can be loaded with small molecules of clarithromycin, nano calcium peroxide (CaO2 ), and Pt nanoparticles (Pt NPs) by ultrasound. Nanomotors can quickly consume gastric acid through the chemical reaction of CaO2 to temporarily neutralize gastric acid. The product hydrogen peroxide (H2 O2 ) is catalytically decomposed into a large amount of oxygen (O2 ) by Pt NPs. The local concentration gradient of O2 bubbles causes it to be expelled from the nanobottles through a narrow opening, and then push the nanobottles forward to provide maximum release and prodrug efficacy. Experiments in animal models show that 15 mg nanomotors can safely and quickly neutralize gastric acid in the stomach and simultaneously release prodrugs to achieve good therapeutic effects without causing acute toxicity. H. pylori burden in mice was 2.6 orders of magnitude lower than that in the control group. The stomach returns to normal pH within 1 d after administration.

[PMID: 33152967 DOI: 10.1016/j.ijporl.2020.110376] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/28/2020] [Revised: 09/07/2020] [Accepted: 09/07/2020] [Indexed: 11/24/2022]
Abstract
OBJECTIVES To detect Helicobacter Pylori [HP] in tonsillar tissue of recurrent tonsillitis cases and assess the possible role of Laryngopharyngeal reflux [LPR] in tonsillar HP infection. METHODS A prospective study was done on the cited subject in a sample size of 50 paediatric patients [Age group: 6-18 years] suffering from recurrent tonsillitis. LPR was diagnosed by Reflux Symptom index [RSI] and Reflux Finding score [RFS]. A score of more than 7 and 13 was regarded as significant for RFS and RSI respectively. Patients with both scores significant were regarded to be suffering from LPR. Tonsillar specimen after tonsillectomy were subjected to urease test, histopathology [ Modified Giemsa Staining] and culture to detect HP. A minimum of two positive tests of the mentioned three were taken as gold standard to diagnose colonization of HP. Tabulated data was statistically analysed. RESULTS We recorded an incidence of 9% [18 cases] for LPR in recurrent tonsillitis. No case of HP colonization of tonsils was detected in this case series, even in patients of LPR. CONCLUSION We conclude that tonsils are not an extra gastric reservoir of HP. In addition, there is no aetiological relationship between recurrent tonsillitis and HP. And lastly, LPR is not a significant factor for colonization of tonsils by HP.

Abstract
The bacteria Helicobacter pylori (H. pylori) have been identified in the extragastric tissues in the head and neck. The origin and pathogenicity of these bacteria in the head and neck are not known. Gastric reflux and nasal or oral routes are the possible modes of spread. In many sinonasal, pharyngeal, laryngeal, and middle ear disorders, laryngopharyngeal reflux has been identified as a contributing or causative factor. One possible mode by which laryngopharyngeal reflux may contribute is by seeding of the extragastric mucosa with H. pylori. The clinical significance of the discovery of H. pylori in extragastric tissues in the head and neck is unclear. There is no evidence of a pathologic or active role of H. pylori in otorhinolaryngological disorders. The suggestion that the sinonasal cavities and pharynx may serve as a reservoir for H. pylori and that reinfection of the stomach occurs after eradication therapy awaits further studies for confirmation. No connection was observed between H. pylori found in the stomach and H. pylori found in the head and neck. Also, these bacteria, found in the head and neck tissues, may be accidental or innocent bystanders that do not affect the pathways of otolaryngological and gastroduodenal diseases. This review examines the evidence for a possible relationship of H. pylori with otorhinolaryngological diseases.

Abstract
The objective of the present work was to elucidate the specific features of the clinical picture of allergic rhinitis in the pregnant women. The study included 156 pregnant women presenting with the persisting form of the disease and 63 patients having its intermitting form. The character of the endoscopic manifestations of rhinitis, chronic tonsillitis, and gastroesophageal reflux was evaluated with the use of a scoring system. The progressive development of the clinical symptoms of allergic rhinitis during pregnancy related neither to the contacts with allergens nor to the discontinuation of pharmacotherapy was documented in 33 and 23% of the patients presenting with the persistent and intermitting forms of the disease, respectively. The symptoms of rhinitis in the pregnant women may be influenced by the presence of gastroesophageal reflux (the endoscopic evidence of this condition was documented in 84.6% of the examined patients with persisting form of the disease and in 40.3% of those having intermitting form) and chronic tonsillitis (purulent contents in the palatine tonsil lacunes were found in 46.8 and 40.3% of the women presenting with the persisting and intermitting forms of allergic rhinitis respectively). In 42% of the cases, the cause behind the negative dynamics or the absence of any dynamics during the treatment of allergic rhinitis was the withdrawal of the prescribed pharmacotherapy by the patients themselves. This observation gives evidence of the importance of explaining to the pregnant women suffering from allergic rhinitis the necessity of compliance with the prescribed treatment modalities in order to reduce the probability of development of complications of this condition.

Abstract
BACKGROUND The purpose of the study was to assess the prevalence of Helicobacter pylori infection among the junior high school students in city Grudziądz, Poland. MATERIALS AND METHODS A prospective cross-sectional study among second junior high school students was conducted from September 2008 to June 2015 during seven consecutive school years. The studied group was 3241 students 13-17 years old. The 13 C-urea breath test (UBT) was administered to all participants for current H. pylori infection. Clinical, sociodemographic, and hygienic risk factors for H. pylori positivity were analyzed in children with positive and negative UBT. RESULTS Urea breath test was performed and results were obtained for 3067 of 3241 children, including 723 children (23.6%) with positive result (group 1) and 2344 children (76.4%) with negative result (group 2). The prevalence of H. pylori infection was not different in subsequent seven school years (P = 0.06) and depending on the gender (P = 0.57). In group 1 the cough and in group 2 the epigastric discomfort occurred more frequent (P = 0.04 and P = 0.002, respectively). In multivariate analysis, factors positively associated with prevalence of H. pylori were age >16 years (OR = 2.556; 95%CI 1.293-5.025), living in old town district (OR = 1.374; 95%CI 1.097-1.723), consumption of raw vegetables (OR 1.305; 95%CI 1.038-1.642) or unboiled water (OR = 1.444; 95%CI 1.138-1.832) and using collective catering facilities (OR 1.338; 95%CI 1.039-1.724). Having a cat was protective against H. pylori (OR 0.78; 95%CI 0.614-0.991). CONCLUSIONS Over the past 10 years, the prevalence of H. pylori infection in Polish adolescents has decreased. H. pylori infection remains problem closely associated with socioeconomic and sanitary conditions. Our results are important to develop prevention strategies for H. pylori-related diseases.

Abstract
The review of the most important recent publications concerning the relation of Helicobacter pylori with peptic ulcer disease (PUD), noninvestigated and functional dyspepsia, and gastroesophageal reflux disease (GERD) is presented. H. pylori remains the main etiopathogenetic factor in complicated and uncomplicated PUD. Nevertheless, the role of nonsteroidal anti-inflammatory drugs (NSAIDs) and aspirin is increasing. The novel data did not confirm that PUD caused by NSAIDs and aspirin is less symptomatic. The role of glucocorticoids, immunosuppressants, and antidepressants seems to be of some importance. Although the involvement of H. pylori in functional dyspepsia is controversial, several data support the importance of H. pylori-induced gastritis in the pathogenesis of dyspeptic symptoms. Recent interventional studies have reported that H. pylori eradication improves dyspepsia mainly in areas with a high prevalence of this bacterium. Novel data regarding the relation of gastrointestinal peptides, ghrelin and obestatin, with H. pylori infection are also presented. Intriguing findings support the involvement of the gastric microbiota in the causation of chronic functional dyspepsia. Finally, some data concerning negative, positive, or neutral associations of H. pylori with gastroesophageal reflux disease (GERD) were published. In this context, today there is no evidence indicating that H. pylori eradication could worsen the symptoms or the course of GERD.

Abstract
AbstractObjectiveTo 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.MethodsNasal 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.ResultsThe 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.ConclusionH 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.

Abstract
BACKGROUND Several studies have indicated the larynx as possible Helicobacter pylori (H. pylori) reservoirs. This study explored the association between H. pylori and vocal fold leukoplakia. METHODS The case-control study involved 51 patients with vocal fold leukoplakia and 35 control patients with vocal polyps. Helicobacter pylori was detected in tissues by the rapid urease test, nested polymerase chain reaction (PCR), and single-step PCR. The H. pylori-specific immunoglobulin antibodies were detected in plasma by enzyme-linked immunosorbent assay (ELISA). RESULTS Helicobacter pylori-positive rate of vocal fold leukoplakia and vocal polyps was 23.5% versus 11.4% (P = .157), 37.2% versus 14.3% (P = .020), 27.5% versus 8.6% (P = .031), and 70.6% versus 68.6% (P = .841) detected by rapid urease test, nested PCR, single-step PCR, and ELISA, respectively. Regression analysis indicated that H. pylori infection (P = .044) was the independent risk factor for vocal fold leukoplakia. CONCLUSION Helicobacter pylori infection exists in the larynx and may be associated with vocal fold leukoplakia.
