Abstract
Purpose The primary aim of this review was to identify environmental irritants known to trigger chronic cough through the life span and develop a comprehensive clinically useful irritant checklist. Method A scoping review was conducted using the Preferred Reporting Items for Systematic Review and Meta-Analysis Extension for Scoping Reviews, checklist, and explanation. English-language, full-text resources were identified through Medline, PsycINFO, SPORTDiscus, Web of Science, and ProQuest Dissertations and Theses Global. Results A total of 1,072 sources were retrieved; of these, 109 were duplicates. Titles of abstracts of 963 articles were screened, with 295 selected for full-text review. Using the exclusion and inclusion criteria listed, 236 articles were considered eligible and 214 different triggers were identified. Triggers were identified from North America, Europe, Africa, Asia, and Australia. Occupational exposures were also delineated. Conclusions A clinically useful checklist of both frequently encountered triggers and idiosyncratic or rare triggers was developed. The clinical checklist provides a unique contribution to streamline and standardize clinical assessment of irritant-induced chronic cough. The international scope of this review extends the usefulness of the clinical checklist to clinicians on most continents.

Abstract
The objectives of this prospective study are to determine the prevalence of laryngopharyngeal reflux (LPR) symptoms in patients with endoscopic esophagitis, to investigate the relationship between LPR symptoms and upper abdominal symptoms of gastroesophageal reflux disease (GERD) and to compare the treatment responses of both symptom groups. 120 consecutive patients having complaints of GERD were included. Group I consisted of 62 patients with a diagnosis of endoscopic esophagitis. The second group consisted of 58 subjects with no detectable pathology at gastroscopy. LPR symptoms and upper abdominal symptoms were graded. Proton pump inhibitors (PPI) were prescribed to patients. Both groups of symptoms were compared in two groups of patients. The improvement in symptoms was evaluated after treatment. The frequencies of LPR symptoms were statistically higher in patients with endoscopic esophagitis. All LPR symptoms were statistically relieved in their frequency after treatment. The decrease in LPR symptom scores after treatment in group I was statistically significant. FSSG (frequency scale for the symptoms of GERD) scores were statistically higher in group I than in group II before treatment. After treatment, FSSG scores were significantly decreased in group I. There was statistically significant positive correlation between the LPR symptom scores and FSSG scores before treatment. In conclusion, there is a high incidence of LPR symptoms and upper abdominal symptoms in patients with endoscopic esophagitis. LPR and upper abdominal symptoms responded well to antireflux treatment in patients with endoscopic esophagitis.

Abstract
PURPOSE OF REVIEW Laryngopharyngeal reflux should no longer be underestimated because of its negative impact on the lives of patients and its potentially dangerous long-term complications. RECENT FINDINGS Both laryngopharyngeal reflux and gastroesophageal reflux disease are caused by mucosal injury from acid and pepsin exposure, but the esophagus has intrinsic antireflux defenses that prevent mucosal injury (bicarbonate production, mucosal tissue resistance and esophageal motor function with acid clearance) whereas the pharynx and the larynx do not. Symptoms felt to be most related to reflux (>or= 95%) are throat clearing, persistent cough, heartburn/dyspepsia, globus sensation (lump in the throat) and voice-quality change, while the physical examination findings include (>or= 95%) arytenoid erythema, vocal-cord erythema and edema, posterior commissure hypertrophy, and arytenoid edema. In this regard, the reflux symptom index and the reflux finding score are very useful clinical tools. Patients are proposed an empirical therapeutic trial including behavioural and dietary recommendations and a 3-month twice-daily proton-pump inhibitor therapy. The proton-pump inhibitor should be taken 30-60 min before meals. Nonresponders undergo an assessment, ideally based on esogastroduodenoscopy and ambulatory multichannel intraluminal impedance and pH monitoring. Transnasal esophagoscopy in the outpatient setting is a safe alternative. When medical management fails, patients with demonstrable high-volume reflux and lower sphincter incompetence are often candidates for surgical intervention. SUMMARY The algorithm proposed by Ford has structured and confirmed our attitude on a day-to-day basis.

Abstract
PURPOSE OF REVIEW Laryngopharyngeal reflux has shown high prevalence and it is an interesting issue for otorhinolaryngologists, head and neck surgeons, and gastroenterologists. The present paper presents the most recent findings in diagnosis and management of laryngopharyngeal reflux. RECENT FINDINGS Clinical presentation of laryngopharyngeal reflux is widely varied and it may be manifested by a wide range of signs and symptoms. Other diseases that affect the larynx may also show the same signs and symptoms, such as, for example, vocal abuse, allergy, asthma, sinusitis, and smoking. Overvaluation of signs and symptoms related to reflux may be responsible for overdiagnosis of laryngopharyngeal reflux disease. The 24-hour dual-probe pH monitoring is considered the gold standard for the diagnosis of laryngopharyngeal reflux disease, and is essential in cases of pharyngolaryngeal complaints. The management of laryngopharyngeal reflux cases should be based on severity of symptoms, laryngoscopic findings, and frequency of reflux episodes. Proton-pump inhibitors are the preferred drugs for managing patients with laryngopharyngeal reflux and the best control can be achieved by prescribing high doses, twice a day. Patients that do not respond satisfactorily to clinical management are candidates for surgical fundoplication. SUMMARY Laryngopharyngeal reflux is characterized by a set of signs and symptoms resulting from extraesophageal manifestations of gastroesophageal reflux disease; however, this set of signs and symptoms may be related to other causes and the results of management, based on clinical presentation, vary widely and have low cure index.

Abstract
OBJECTIVES To confirm feasibility of transnasal placement of a wireless pH-monitoring capsule in the upper esophagus, and to determine the positive predictive value of LPR and GERD signs and symptoms for diagnosis of LPR in patients with OSAHS. STUDY DESIGN Prospective, nonrandomized, IRB-approved study of 89 OSAHS patients with and without symptoms and signs of LPR. METHODS After complete history including QOL survey and fiberoptic laryngoscopy, patients underwent transnasal placement of the pH-monitoring capsule and wireless data collection for 24 hours. RESULTS 77 of 89 consecutive patients underwent successful placement of wireless pH-monitoring capsule (86.5% success rate) and completed the study. 55 (71.4%) OSAHS patients had positive pH studies. 10.4% of these patients reported no symptoms or signs of LPR, indicating occult disease. CONCLUSION Success rates of placement, tolerability, morbidity, and complications are excellent. Wireless upper esophageal pH monitoring is safe and effective for diagnosing LPR in patients with OSAHS.

Abstract
BACKGROUND Published yields of pH monitoring for suspected laryngopharyngeal reflux (LPR) vary greatly. Hypopharyngeal pH artifacts may be responsible for these inconsistencies. OBJECTIVE To determine the impact of potential artifacts on pH monitoring of the hypopharynx and esophagus. METHODS Patients with suspected LPR were prospectively studied. Single-catheter, triple-sensor pH monitoring was performed off antireflux therapy. Subjects recorded meal times and marked liquid swallows outside of meals on the data recorder. Results were analyzed by excluding six potential pH artifacts individually and all together. Positive pH test was defined as three or more reflux episodes in hypopharynx, total percent of time pH less than 4 was 1.0% or greater in the proximal esophagus, and total percent of time pH less than 4 was 4.2% or greater in the distal esophagus. Wilcoxon rank sum and chi-square tests were used. RESULTS Thirty-eight subjects (24 females; median age, 47 yr) completed the study. A total of 2,225 hypopharyngeal pH drops less than 4 were identified; 48% were short pH drops at less than 5 seconds, 17% within meal periods, 16% liquid swallows outside of meals, 16% isolated proximal pH drops, 12% pH out of range, and 5% pH drift. Eighty percent of the hypopharyngeal pH drops were at least one of the potential pH artifacts. The yield of the hypopharyngeal sensor was reduced by 45% (from 92% to 47%) after all potential pH artifacts were excluded. Yields of proximal and distal esophageal pH sensors were reduced by 19% and 8%, respectively, significantly less than the hypopharyngeal sensor (P < .01). CONCLUSIONS Patients should record all liquid swallows outside of meals. It is essential to exclude all potential artifacts for hypopharyngeal pH monitoring in patients with suspected LPR.

Abstract
The role of laryngopharyngeal reflux (LPR) on hoarseness is widely assumed and accepted. Few articles present objective information on the subject. One of the main problems in establishing a relationship is our lack of knowledge of what is normal. We compared patients with chronic hoarseness and healthy controls to establish three goals: (1) to demonstrate the presence of additional symptoms and signs of LPR in patients with hoarseness; (2) to find the prevalence of LPR by utilizing 24 h double-probe in patients with hoarseness and compare it with that of the control group; (3) to contribute data to establish prevalence of LPR in healthy population. Forty-three patients with hoarseness and 20 healthy volunteers were enrolled in the study. All the patients in the study group had hoarseness of more than 3 months duration. The subjects recieved videolaryngoscopic evaluation and 24 h double-probe pH monitoring, and the results were compared. In the study group, 27 patients (62.8%) out of 43 had LPR episodes, compared to 6 (30%) of 20 healthy volunteers. Mean number of LPR episodes recorded by the pharyngeal probe was 7.0 [standard deviation (SD): 8.8] in 24 h, and this was significantly higher than that of the healthy controls [0.9/24 h (SD: 1.9)] (P = 0.003). Mean number of LPR episodes of the study group in upright position was 5.8 (SD: 7,0) and in supine position was 1.2 (SD: 3.3). These numbers were also significantly higher from the controls (P = 0.005 and P = 0.014 respectively). The results of this study show that: (1) most common additional symptoms were heartburn and chronic throat clearing and most common finding is pachydermia; (2) LPR incidence in patients with chronic hoarseness is significantly higher than the LPR incidence in healthy controls; (3) LPR is present in healthy people. However, the severity of LPR seems to be the causative factor rather than its presence.

Abstract
Laryngopharyngeal reflux (LPR) as a causative irritating factor in the development of laryngeal carcinoma has been suggested. However, the association between LPR and laryngeal carcinoma remains unclear. The aim of this study was to compare the prevalence and severity of reflux between patients with laryngeal carcinoma and clinical LPR. The intention was to find out if a correlation exists between the laryngeal findings and the level of acid reflux. The study population consisted of 29 patients with laryngeal cancer (group I), 33 LPR patients with normal laryngeal findings (group II) and 70 LPR patients with related laryngeal pathology (group III). The results of 24-h, double-channel ambulatory esophageal pH monitoring were analyzed comparing the three groups. The occurrence and severity of abnormal acid reflux at the upper and lower esophageal segments were evaluated. The incidence of LPR or gastroesophageal reflux (GER) did not vary in any of the three groups (LPR was present in 62, 42 and 56% of the patients, while GER was present in 45, 24 and 37% of the patients, respectively). Patients with LPR or GER from the three groups did not differ significantly in terms of the number of acid reflux episodes and percentage of times when the pH was <4. Our data do not support the hypothesis that LPR can be an independent risk factor in the development of larynx cancers. However, the data also do not thoroughly exclude the possibility. The reason why LPR leads to variable pathologies in the larynx may be uncovered by studies probing the differences between patients via detailed examinations of the local anti-reflux barriers such as epithelial morphology and functions.

Abstract
BACKGROUND Endogenous airway acidification evaluated as pH in exhaled breath condensate (EBC) has been described in patients with chronic cough. Proton pump inhibitors improve gastro-oesophageal reflux (GOR)-associated cough. METHODS We examined pH levels in EBC and capsaicin cough response in 13 patients with chronic cough (mean age 41 years, SD 9) associated with GOR before and after omeprazole treatment (40 mg/day for 14 days) and its relationship with clinical response. RESULTS Omeprazole abolished symptoms associated with GOR. Patients with chronic cough had an EBC pH of 8.28 (SD 0.13) prior to treatment but this did not change with omeprazole treatment. There was a significant improvement in the Leicester Cough Questionnaire symptom scores from 80.8 points (SD 13.2) to 95.1 (SD 17) (p = 0.02) and in a 6-point scale of cough scores, but there was no change in capsaicin cough response. CONCLUSION An improvement in GOR-associated cough was not associated with changes in EBC pH or capsaicin cough response. These parameters are not useful markers of therapeutic response.

Abstract
Gastroesophageal reflux disease (GERD) is a common, chronic disorder. The main symptom of GERD is heartburn, although a diverse range of symptoms can be associated with the disease including acid regurgitation and epigastric pain. GERD is also a risk factor for Barrett's oesophagus and esophageal adenocarcinoma. The impact of GERD symptoms on patients' lives can be profound and is unrelated to the presence or absence of esophagitis. The impact of GERD can be measured by assessing the patient perspective using Patient Reported Outcomes (PROs). There are two categories of questionnaires that can be used to measure the effect of GERD on health-related quality of life (HRQoL), namely generic and disease or treatment specific. The use of PRO instruments has become more accepted in the assessment of disease treatment. Well-designed instruments that assess physical, psychological and emotional factors can provide clinicians with the data that will promote effective management decisions for the treatment of GERD. The most frequently used instruments in GERD are reviewed here, in terms of their psychometric properties.
