Non-voice-related throat symptoms: comparative analysis of laryngopharyngeal reflux and globus pharyngeus scales

'Persistent throat symptoms' versus 'laryngopharyngeal reflux': a cross-sectional study refining the clinical condition

Objective

Many patients are assessed for chronic symptoms including: dysphonia, ‘globus’, throat clearing, postnasal secretions and cough; commonly grouped together and attributed to ‘laryngopharyngeal reflux’. This study aimed to explore a clinical trial’s baseline dataset for patterns of presenting symptoms, which might provide a more rational basis for treatment.

Design

Baseline data were analysed for participants entering the Trial Of Proton-Pump Inhibitors in Throat Symptoms: age, body mass index, Reflux Symptom Index, Comprehensive Reflux Symptom Score, Laryngopharyngeal Reflux-Health-related Quality of Life questionnaire and Reflux Finding Score (RFS-endoscopic examination). The relationships between the questionnaires and demographic factors were assessed. Exploratory factor analysis (EFA) was conducted on individual symptom items in the combined questionnaires. The EFA factors were applied to a Cluster Analysis of participants, to explore the presence of identifiable patient.

Results

Throat clearing and globus were the highest ranked scores in the 344 participants. Increasing age was inversely associated with symptom severity (p<0.01). There was no relationship between the RFS and any of the three questionnaires. EFA resulted in a seven-factor model with clinically meaningful labels: voice, cough, gastrointestinal symptoms, airway symptoms and dysphagia, throat clearing, lump in throat, and life events. Cluster analysis failed to demonstrate any clinically meaningful clusters of patients.

Conclusion

This study offers a framework for future research and demonstrates that individual symptoms cannot be used to group patients. The analysis supports the use of a broad ‘umbrella’ term such as persistent throat symptoms.

Reliability and Validity of the Turkish Version of the Glasgow-Edinburgh Throat Scale: Use for a Symptom Scale of Globus Sensation in Turkish Population

Objective

In this study, we aimed to translate the Glasgow-Edinburgh Throat Scale (GETS) into Turkish and test its reliability and validity.

Methods

A total of 69 patients with globus sensation and no signs of otolaryngologic or gastroenterological disease in etiology were included in the study. The patients were asked to complete the translated Turkish version (GETS-T) of GETS and the Hospital Anxiety and Depression Scale (HADS).

Results

The Cronbach's alpha coefficient of the patients in the study group was calculated based on the 12 questions in the GETS-T scale and found as 0.868. The correlation between the GETS-T total score and the total HADS score in the study group was found to be very low and statistically insignificant. As a result of factor analysis, it was found that the first 10 problems in GETS-T were divided into two sub-groups, unlike GETS.

Conclusion

Translation of GETS into Turkish (GETS-T) showed high reliability and validity, suggesting that translation and cross-cultural adaptation was appropriate. The GETS-T can be used in studies about globus pharyngeus in future.

Frequency and severity of globus pharyngeus symptoms in patients undergoing thyroidectomy: a pre-post short term cross-sectional study

Background

Globus pharyngeus is a sensation of a lump or foreign body in the throat, sometimes associated with thyroid diseases and surgery. Previous studies investigated this condition with contradictory results, mainly because not standardized instruments of measure were used. The aim of this study was to evaluate the prevalence and severity of globus pattern symptoms in a population of patients three months after a thyroidectomy, and the reduction or increase of pre-existing symptoms or the onset of new symptoms.

Methods

Ninety-five patients (65 women, 30 men, mean age 56.03 ± 12.45) were assessed for globus pattern symptoms before and three months after thyroid surgery (72 patients: benign goiter, 23 patients: papillary cancer). The Glasgow-Edinburgh Throat Scale (GETS) was translated into Italian and used as a validated instrument of measure of the severity of globus pattern symptoms.

Results

The Italian version of the GETS was reliable (Cronbach alpha = 0.85) and valid. Normative data were used to classify patients into 4 groups of severity. A significant decrease of the mean GETS score was observed at the postoperative assessment (13.02 ± 11.84 vs 8.00 ± 11.26; p < 0.01), but beside symptomatic patients who improved we could observe also two other significant groups of patients: asymptomatic patients who developed symptoms and symptomatic patients who remained symptomatic.

Conclusions

The significant decrease of the mean GETS postoperative score was mainly due to the improvement of strongly symptomatic patients. Two other significant outcomes exist and further studies are needed to understand their pathophysiological mechanism.

Honey plus coffee versus systemic steroid in the treatment of persistent post-infectious cough: a randomised controlled trial

BACKGROUND

Persistent post-infectious cough (PPC) is a cough that remains after a common cold or an upper respiratory tract infection for more than three weeks or perhaps for many months. Two of the suggested treatments for PPC are systemic steroid and honey plus coffee.

AIMS

The aim of this study was to evaluate and compare scientifically the therapeutic effects of these two regimens.

METHODS

A double-blind randomised controlled trial was conducted from 2008 to 2011 at the Baqiyatallah University Hospital, Tehran, Iran. Included in the study were 97 adults who had experienced PPC for more than three weeks. Patients with other causes of chronic cough, systemic disease, or abnormal routine laboratory tests were excluded. The participants were distributed into three groups. A jam like paste was prepared which consisted of honey plus coffee for the first group ('HC'), prednisolone for the second group (steroid, 'S'), and guaifenesin for the third group (control, 'C'). The participants were told to dissolve a specified amount of their product in warm water and to drink the solution every eight hours for one week. All the participants were evaluated before treatment and one week after completion of treatment to measure the severity of their cough. The main outcome measure was the mean cough frequency before and after one week's treatment calculated by a validated visual analogue cough questionnaire score.

RESULTS

There were 97 adult patients (55 men) enrolled in this study with the mean of age of 40.1 years. The mean (+/- SD) cough scores pre- and post-treatment were: HC group 2.9 (0.3) pre-treatment and 0.2 (0.5) post-treatment (p < 0.001); steroid ('S') group 3.0 (0.0) pre-treatment and 2.4 (0.6) post-treatment (p < 0.05); control ('C') group 2.8 (0.4) pre-treatment and 2.7 (0.5) post-treatment (p > 0.05). Analysis of variance showed a significant difference between the mean cough frequency before and after treatment in the HC group versus the S group (p< 0.001). Honey plus coffee was found to be the most effective treatment modality for PPC.

CONCLUSIONS

A combination of honey and coffee can be used as an alternative medicine in the treatment of PPC.

Assessing Laryngopharyngeal Reflux Symptoms with the Reflux Symptom Index

Objective. To validate the Reflux Symptom Index (RSI) in Greek patients and estimate the prevalence of laryngopharyngeal reflux (LPR) symptoms in the Greek population.

Study Design. Prospective, controlled validation study.

Setting. Tertiary referral hospital and primary care.

Subjects and Methods. For validation purposes, the instrument was administered to 53 patients with confirmed LPR. Sex- and age-matched controls with no LPR or gastroesophageal reflux disease (GERD) symptoms presenting in a primary care setting composed the control group. Reliability and construct validity were statistically appraised. Using the RSI, the authors estimated the prevalence of LPR in a randomly selected sample of the Greek adult population.

Results. The mean (SD) RSI score of the 172 sex- and age-matched controls was 3.2 (3.5). The mean (SD) RSI score of the 53 confirmed LPR patients was 19.9 (6.8). Cronbach α was 0.865. Factor analysis verified that the RSI instrument consists of 2 principal factors. To estimate the prevalence of LPR, a representative sample of the Greek adult population (188 subjects) completed the RSI questionnaire: 36.3% were male, and 29.6% were smokers. Mean (SD) age was 53.4 (17.7) years. The instrument was able to discriminate 16 patients with LPR symptoms with a mean (SD) score of 18.91 (6.39).

Conclusion. The authors evaluated the internal consistency, reliability, and construct validity of the RSI for the Greek population. Factor analysis of the Greek translation of the RSI demonstrated that it can be a reliable tool in the diagnostic approach of LPR patients. Using the RSI, the authors recorded that the prevalence of LPR in a representative sample of the Greek population is 8.5%.
