OBJECTIVES: Mulberry-like changes of the posterior inferior nasal turbinate (MPINT) can lead to nasal obstruction. Extraesophageal reflux (EER) characterized by lower pH causes mucosal inflammation and therefore can contribute to sinonasal pathologies. No prior studies have objectively examined the possible association between acidic pH and MPINT formation. Therefore, this study is aimed to investigate the 24-h pharyngeal pH value in patients with MPINT. STUDY DESIGN: Prospective case-control multi-center study. METHODS: Fifty-five patients with chronic EER symptoms were included in the study. They filled in questionnaires aimed at reflux and sinonasal symptoms (RSI®, SNOT-22) and underwent video endoscopy evaluating the laryngeal findings (RFS®) and the presence or absence of the MPINT. And, 24-h oropharyngeal pH monitoring was used to detect the acidic pH environment in the pharynx. RESULTS: Out of the 55 analyzed patients, 38 had the MPINT (group 1), and in 17 patients, the MPINT was absent (group 2). Based on the pathological RYAN Score, in 29 (52.7%) patients, severe acidic pH drops were detected. In group 1, the acidic pH drops were diagnosed significantly more often (68.4%) compared with those in group 2 (p = 0.001). Moreover, in group 1, a significantly higher median total percentage of time spent below pH 5.5 (p = 0.005), as well as a higher median number of events lasting more than 5 min (p = 0.006), and higher median total number of events with pH drops (p = 0.017) were observed. CONCLUSION: In this study, the MPINT was significantly more often present in patients with acidic pH events detected by 24-h oropharyngeal pH monitoring. Acidic pH in the pharynx might lead to MPINT formation. LEVEL OF EVIDENCE: 3 Laryngoscope, 134:62-68, 2024.

Gastroesophageal reflux disease (GERD) as a possible cause of chronic cough is known for decades. However, more than 75% of patients with extraoesophageal symptoms do not suffer from typical symptoms of GERD like pyrosis and regurgitations and have negative upper gastrointestinal endoscopy. For such a condition term laryngopharyngeal reflux (LPR) was introduced and is used for more than two decades. Since the comprehensive information on relationship between chronic cough and LPR is missing the aim of this paper is to summarize current knowledge based on review of published information during last 13 years. Laryngopharyngeal reflux is found in 20% of patients with chronic cough. The main and recognized diagnostic method for LPR is 24-h multichannel intraluminal impedance-pH (MII-pH) monitoring, revealing reflux episodes irritating the upper and lower respiratory tract mucosa. The treatment of LPR should be initiated with dietary and lifestyle measures, followed by proton pump inhibitor (PPI) therapy and other measures. Despite progress, more research is needed for accurate diagnosis and targeted therapies. Key areas for exploration include biomarkers for diagnosis, the impact of non-acid reflux on symptom development, and the efficacy of new drugs. Further studies with a focused population, excluding other causes like asthma, and using new diagnostic criteria for LPR are essential. It's crucial to consider LPR as a potential cause of unexplained chronic cough and to approach diagnosis and treatment with a multidisciplinary perspective.

OBJECTIVE: This study was designed to evaluate the possibility of predicting the minimum size of septal resection for safe tumor extraction in transnasal paraseptal pituitary adenoma resection from preoperative computed tomography scans. METHODS: A retrospective CT scan analysis was performed on 20 patients who underwent endoscopic pituitary surgery at the University Hospital in Ostrava. Virtual insertion of the straight instrument into the sphenoid cavity was simulated using a CT scan. The minimum septal resection size was predicted and compared to various diameters in the nasal cavity. The results were then compared with cadaveric dissections, in which septal resections were performed at 1 cm and 2 cm distances from the anterior sphenoid wall. The association between cadaver dissections and CT scan results was studied. RESULTS: A total of 20 patients who underwent endoscopic transnasal surgery for pituitary adenoma between the years 2020 and 2021 were enrolled in the study. The mean virtual posterior septal size resection needed to reach the medial edge of the ICA with the straight instrument, without infracturing the nasal septum, was 13.2 mm. In cadavers with a 1 cm posterior septal resection, the medial edge of the ICA was reached with the straight instrument. In 2 cm resections, it was possible to reach beyond the lateral edge of the ICA. CONCLUSION: There is no significant correlation between the minimum septal size resection and measured diameters in the nasal cavity. According to our study, a 1 cm resection is sufficient for a non-extended pituitary tumor extraction. More extensive septal resections allow for better maneuverability and overview in the surgical field.

Úvod a cíl: Mimojícnový reflux (EER) je zpětný tok žaludečních šťáv (nejčastěji kyselých) nad úroveň horního jícnového svěrače (tím se liší od gastroezofageálního refluxu). Příznaky mimojícnového refluxu jsou nespecifické, různé intenzity a závisí na lokalizaci patologického působení refluxátu. V případě působení refluxátu na zubní tkáň může EER přispívat ke vzniku zubních erozí. Vedle refluxátu jsou zvažovány i další faktory, jako je složení slin a mikrobiom ústní dutiny. V posledních letech došlo k významnému posunu v chápání mimojícnového refluxu, zejména patogeneze a z toho vyplývajících důsledků pro diagnostiku a léčbu. Cílem článku je informovat o EER a podat přehled o současných možnostech diagnostiky a jeho léčby a také shrnout výsledky nedávných metaanalýz týkajících se role EER při vzniku zubních erozí. Metodika: Podkladem pro článek byly odborné publikace získané v databázích PubMed, Cochrane Library a Scopus z let 2002–2022. Publikace se vyhledávaly pomocí kombinace klíčových slov v anglickém i českém jazyce: mimojícnový reflux, gastroezofageální reflux, zubní eroze. Celkem bylo analyzováno 21 studií pojednávajících o souvislosti mezi refluxem a zubními erozemi prostřednictvím přehledových, klinických prospektivních a retrospektivních studií a metaanalýz. Zahrnuté studie byly provedeny u dospělé populace a informace o gastroezofageálním refluxu ve vztahu ke vzniku zubních erozí byly využity jen za předpokladu jeho diagnostiky multikanálovým intraluminálním monitorováním pH impedance. V první části článku je prezentován současný pohled na patofyziologii, diagnostiku a léčbu EER. Druhá část shrnuje poznatky o dentálních erozích. Ve třetí části jsou prezentovány studie zabývající se vlivem EER na zubní eroze. Výsledky: Získané informace svědčí o vyšší prevalenci dentálních erozí u pacientů s EER v porovnání se zdravou populací. Důvodem je, že kyseliny jak exogenního, tak endogenního původu hrají důležitou roli v rozpouštění minerálů skloviny, což ve výsledku vede ke vzniku zubních erozí. Na základě analyzovaných studií nelze v současnosti považovat vztah mezi refluxem a vznikem zubních erozí za kauzální, a to zejména z důvodu nízké kvality studií. Autoři doporučují provádění dalších studií, ve kterých by byl vztah mezi EER a zubními erozemi dále zkoumán. Závěr: Na základě dosavadních poznatků lze předpokládat účast mimojícnového refluxu na rozvoji dentálních onemocnění. Možnou souvislost podporuje i fakt, že prevalence dentálních erozí v populaci s refluxem nebo prevalence refluxu v populaci s dentálními erozemi je ve srovnání se zdravou populací mnohem vyšší. V budoucnosti je potřeba dalších studií, které by zkoumaly kauzalitu mimojícnového refluxu při vzniku zubních erozí.
Introduction, aim: Extraesophageal reflux (EER) is the backflow of gastric fluids (most often acidic) above the level of the upper esophageal sphincter (it differs from gastroesophageal reflux). The symptoms of extraesophageal reflux are non-specific, of varying intensity and depend on the location of the pathological action of the refluxate. In the case of the effect of refluxate on the hard dental tissue, EER can contribute to the formation of dental erosions. In addition to refluxate, other factors such as the composition of saliva and the microbiome of the oral cavity are discussed. In recent years, there has been a significant shift in the understanding of extraesophageal reflux, especially the pathogenesis, and the resulting implications for diagnosis and treatment. The aim of the article is to inform about EER and give an overview of the current possibilities of diagnosis and its treatment, as well as to summarize the results of recent meta-analyses regarding the role of EER in the development of dental diseases. Methods: The basis for the presented article was professional publications obtained in the PubMed, Cochrane Library and Scopus databases from 2002 to 2022. Publications were searched using a combination of keywords in English and Czech languages: extraesophageal reflux, gastroesophageal reflux, dental erosion. A total of 21 studies discussing the association between reflux and dental erosions were analyzed through review, clinical prospective and retrospective studies and meta-analyses. The included studies were conducted in the adult population and information on gastroesophageal reflux in relation to the occurrence of dental erosions was used only if it was diagnosed by multichannel intraluminal pH impedance monitoring. The first part of the article presents a current view of the pathophysiology, diagnosis and treatment of EER. The second part summarizes knowledge about dental erosions. In the third part, studies dealing with the effect of EER on dental erosion are presented. Results: The obtained information indicates a higher prevalence of dental erosions in patients with EER compared to the healthy population. The reason is that acids of both exogenous and endogenous origins play an important role in dissolving enamel minerals, which ultimately leads to tooth erosion. Based on the analyzed studies, the relationship between reflux and the development of dental erosions cannot currently be considered causal, mainly due to the low quality of the studies. The authors recommend that further studies investigating the relationship between EER and dental damage should be conducted. Conclusions: Based on the findings, it can be assumed that extraesophageal reflux is involved in the development of dental diseases. A possible link is also supported by the fact that the prevalence of dental erosions in population with reflux or the prevalence of reflux in the population with dental erosions is much higher compared to the healthy population. In the future, however, further studies are needed to investigate the causality of extraesophageal reflux in the occurrence of dental erosions.

Importance: To the authors' knowledge, no prior studies have examined the association between inferior turbinate hypertrophy (ITH) and extraesophageal reflux (EER). If EER were a cause or cofactor of ITH, antireflux treatment can be considered prior to surgical intervention. Objective: To evaluate EER presence and severity in patients with different degrees of ITH. Design, Setting, and Participants: Prospective multicentric cohort study conducted at 3 referral centers treating patients with EER and certified for 24-hour monitoring of oropharyngeal pH. The monitoring was performed between October 2020 and October 2021. A total of 94 adult patients with EER symptoms were recruited, 90 of whom were analyzed. Interventions: Nasal endoscopy was performed to determine the degree of ITH, according to the Camacho classification. Presence and severity of EER were examined using 24-hour monitoring of oropharyngeal pH. Main Outcomes and Measures: Primary outcomes were presence of EER according to RYAN Score, total percentage of time below pH 5.5, and total numbers of EER events below pH 5.5. Results: Of the 90 analyzed patients (median [IQR] age, 46 [33-58] years; 36 [40%] male patients), 41 had a maximum of second-degree ITH (group 1), and 49 patients had at least third-degree ITH (group 2), according to the Camacho classification. On the basis of the RYAN Score, EER was diagnosed more often in group 2 (69.4%) than in group 1 (34.1%; difference, 35.3% [95% CI, 13.5%-56.9%]). Moreover, compared with group 1, group 2 exhibited higher median total percentage of time below pH 5.5 (median [IQR], group 1: 2.1% [0.0%-9.4%], group 2: 11.2% [1.5%-15.8%]; difference, 9.1% [95% CI, 4.1%-11.8%]) and higher median total number of EER events (median [IQR], group 1: 6 [1-14] events, group 2: 14 [4-26] events; difference, 8 [95% CI, 2-15] events). Patients with proven EER demonstrated no difference in the degree of ITH between the right and left nasal cavity (Cohen g, -0.17 [95% CI, -0.50 to 0.30]), or between the anterior and posterior parts of the nasal cavity (Cohen g, -0.21 [95% CI, -0.50 to 0.17]). Conclusions and Relevance: In this cohort study, patients with a higher degree of ITH had more severe EER. A possible association between severe ITH and EER was demonstrated.

BACKGROUND: The PeptestTM is a non-invasive diagnostic test for measuring the pepsin concentration in saliva, which is thought to correlate with laryngopharyngeal reflux (LPR). The aim of this study was to investigate the diagnostic value of the Peptest in detecting LPR based on 24-h multichannel intraluminal impedance-pH (MII-pH) monitoring using several hypopharyngeal reflux episodes as criterion for LPR. METHODS: Patients with suspected LPR were examined with the Reflux Symptom Index (RSI), Reflux Finding Score (RFS), fasting Peptest, and MII-pH monitoring. We calculated the accuracy, sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of the Peptest, RSI, and RFS based on the threshold of one and six hypopharyngeal reflux episodes. RESULTS: Altogether, the data from 46 patients were analyzed. When one hypopharyngeal reflux episode was used as a diagnostic threshold for LPR, the accuracy, sensitivity, specificity, PPV, and NPV were, respectively, as follows: 35%, 33%, 100%, 100%, and 3%, for the Peptest; 39%, 40%, 0%, 95%, and 0%, for the RSI; and 57%, 58%, 0%, 96%, and 0%, for the RFS. The accuracy, sensitivity, specificity, PPV, and NPV of the Peptest for diagnosing gastroesophageal reflux disease (GERD) were 46%, 27%, 63%, 40.0%, and 48%, respectively. CONCLUSIONS: A positive Peptest is highly supportive of a pathological LPR diagnosis. However, a negative test could not exclude LPR.
