Rhinogenic Laryngitis, Cough, and the Unified Airway

To investigate the prevalence of self-reported dysphonia and dysphagia in patients with positive allergy test in comparison to patients with negative allergy tests.

A total of 52 patients who presented to the allergy clinic of a tertiary medical referral center for skin testing between June 2019 and December 2019 were were recruited for this study. Demographic data included age, gender, history of smoking, family history for eczema, atopy, asthma, food and drug allergy. A control group of 20 subjects was matched according to age and gender. All subjects were asked to fill the voice handicap index -10 and the eating assessment tool (EAT-10) questionnaires.

Thirty-six of 52 patients were positive for at least one allergen, and 23 tested positive for at least three allergens. On the other hand, there was no significant difference in the mean score of VHI-10 in patients with allergy to at least one allergen, in comparison to patients with no allergy (3.667 vs 3.066, respectively, P value 0.307). Similarly, there was no significant difference in the mean score of EAT-10 between the two groups (0.305 vs 0.00, respectively, P value 0.270). There was also no significant difference in the mean score of VHI-10 in patients with allergy to at least three allergens in comparison to patients with no allergy (3.304 vs 3.066, respectively, P-value 0.603). Similarly, there was no significant difference in the mean score of EAT-10 between the two groups (0.435 vs 0.00, respectively, P-value 0.667). There was a significant difference in mean VHI-10 scores between patients testing positive for at least one allergen and the control group (P = 0.0002).

The results of this investigation did not show any significance in the prevalence of self-reported dysphonia and dysphagia in patients with positive allergy skin testing in comparison to those with negative allergy skin-testing. More clinical studies on the prevalence of self-reported phonatory complaints in patients with allergy are warranted.

Latest literature proposes laryngopharyngeal reflux (LPR) as the underlying contributory factor for chronic inflammation in both upper and lower airways. In this study, we investigated LPR symptoms and signs of CRS patients and the various factors on their LPR symptoms and signs. We also evaluated the effect of the LPR symptoms and signs of CRS patients after endoscopic sinus surgery (ESS).

We performed a retrospective analysis from 91 patients who underwent primary ESS. They were assessed for LPR symptoms with Reflux Symptom Index (RSI) and Reflux Finding Scores (RFS) before ESS. Sino-Nasal Outcome Test (SNOT)-22, Lund–Mackay (LM) scoring system, and Lund-Kennedy (LK) scoring system were evaluated for CRS severity. They had to fulfill SNOT-22, RSI, and RFS at 6 months after surgery.

Nasal polyps, smoking, asthma, allergy, LM scores and LK scores didn't have significant correlations with preoperative RSI and RFS (P > .05 for all). RSI had significant correlations with SNOT-22 preoperatively and postoperatively (P < .05 for all). RFS had a significant correlation with postoperative SNOT-22 (P = 0.034). RSI and RFS decreased significantly more after ESS (P < 0.001 for both). Smoking had a significant effect on the postoperative RFS (P = 0.003). Non-smoker showed significantly lower scores of postoperative RFS (P = .0.003).

Our study suggests that subjective CRS symptoms were related with subjective LPR symptoms and ESS was effective in reducing signs and symptoms of LPR in CRS patients. Especially, smoking was associated with less improvement of laryngoscopic findings after ESS.

To describe the prevalence of laryngopharyngeal reflux (LPR)-related symptoms in allergy patient using the Reflux Symptom Index (RSI) by Belafsky et al and the Reflux Symptom Score (RSS) by Lechien et al.

A total of 84 patients were enrolled in this study. Fifty-two consecutive patients were asked to fill RSI. Similarly, 32 patients were asked to fill RSS. Demographic data included age, gender, history of smoking, family history for eczema, atopy, asthma, food and drug allergy.

Fifty-seven of the 84 patients were positive for at least one allergen and hence were diagnosed with allergy. Of the 52 patients who received the RSI, 36 patients were allergic to at least one allergen (36/52). Of the 32 patients who filled the RSS, 21 tested positive for at least one allergen (21/32). There was no significant difference in the number of positive RSI scores (>13) between patients with allergy to at least one allergen in comparison to patients with no allergy (P = 0.329). There was a significant difference in the number of positive RSS scores (>13) between patients with allergy to at least one allergen in comparison to patients with no allergy (P-value 0.0345). The odds of having RSS >13 in an allergic patient was significant (OR = 5.6, CI 95% = 1.15-27.37).

The results of this study provide evidence that patients with allergy have increased incidence of LPR related symptoms using the RSS. The cross-cutting in the clinical picture of patients with allergy and LPR stresses the need for objective testing such as double probe Ph-metry and impedance to diagnose this latter. Future studies are needed to explore further the cause-effect relationship between allergy and LPR.

To determine predictive fiberoptic findings of upper airway in children with allergic rhinitis.

129 children had fiberoptic evaluation of nasal cavity, pharynx and larynx. They were divided into allergic rhinitis group and normal group based on skin prick test results. All video recordings were randomly reviewed by three independent national board-certified otolaryngologists who were blinded to the clinical details and outcomes of the participants’ allergy testing. Each physician assessed and documented 10-item questionnaire. Intra-rater, inter-rater reliability and correlation between items and allergic status was calculated.

Intra-rater reliability was moderate to perfect for all physicians on all items (kappa = 0.578–0.962). Inferior turbinate hypertrophy (κ = 0.714, p = 0.02), middle turbinate hypertrophy (κ = 0.728, p = 0.01), discoloration of inferior turbinate (κ = 0.685, p = 0.01), adenoid hypertrophy (κ = 0.662, p = 0.02) had good inter-rater reliability and these findings were predictive of allergic rhinitis. Adenoid hypertrophy was less encountered in allergic rhinitis. All other endoscopic findings beyond the nasal cavity were not predictive for allergic rhinitis in children.

Nasal cavity findings including inferior turbinate hypertrophy, middle turbinate hypertrophy, discoloration of inferior turbinate and adenoid tissue assessment rather than pharyngolaryngeal findings are predictive of allergic rhinitis in children.

Allergies are among the most common chronic conditions worldwide affecting 10%–30% of adult individuals and 40% of children. Phonation can be affected by different allergic conditions in various ways. The role of allergy in phonation has been under-researched and poorly understood and the respective literature is poor. Several studies have investigated the role of certain allergic diseases in phonation. In this review, we tried to include all allergic conditions that can affect voice production.

We conducted a bibliography review looking for allergic conditions that can affect phonation. Allergic asthma, allergic laryngitis, allergic rhinitis and sinusitis, oral allergy syndrome, and angioedema were included in our search.

The literature on the impact of allergy in phonation remains poor and many key questions concerning basic information for epidemiology, pathophysiology, and larynx pathology in allergic patients with phonation problems still remain unanswered.

The role of allergy in voice production remains underinvestigated and many basic questions still remain open. Further research is needed to improve our understanding for these very common conditions.

L’auteur présente une revue de la littérature sur la laryngite allergique, qui est une pathologie encore trop sous-diagnostiquée à ce jour. L’insuffisance de diagnostic peut être liée, soit à la complexité des symptômes, soit aux plaintes trop peu importantes par rapport au reste du tableau clinique ou liée à la méconnaissance de la pathologie. Les symptômes du patient qui peuvent consister entre autres en une dysphonie ou aphonie sont, cependant, très gênants dans un contexte social où la communication prend beaucoup d’importance. L’allergologue, l’ORL et le phoniatre pourront enfin collaborer ensemble afin d’optimaliser le diagnostic.

The author presents a review of the literature concerning allergic laryngitis. This condition continues to be underdiagnosed today. The inadequacy of diagnosis may be due to the complexity of symptoms or to patient complaints that seem trivial against the overall clinical picture, or to poor knowledge of the disease. The patient's symptoms, which may include dysphonia or aphonia, are nevertheless very troublesome in social contexts where communication is very important. Ultimately, allergists, ENT specialists and phoniatricians may work together to ensure optimal diagnosis.
