Food-induced anaphylaxis in infancy compared to preschool age: A retrospective analysis.

OBJECTIVE: Little is known regarding food anaphylaxis in infancy. We aimed to describe specificities of food anaphylaxis in infants (≤12 months) as compared to preschool children (1-6 years). METHODS: We conducted a retrospective study of all food anaphylaxis cases recorded by the Allergy Vigilance Network from 2002 to 2018, in preschool children focusing on infants. RESULTS: Of 1951 food anaphylaxis reactions, 61 (3%) occurred in infants and 386 (20%) in preschool children. Two infants had two anaphylaxis reactions; thus, we analyzed data among 59 infants (male: 51%; mean age: 6 months [SD: 2.9]); 31% had a history of atopic dermatitis, 11% of previous food allergy. The main food allergens were cow's milk (59%), hen's egg (20%), wheat (7%) and peanut (3%) in infants as compared with peanut (27%) and cashew (23%) in preschool children. Anaphylaxis occurred in 28/61 (46%) cases at the first cow's milk intake after breastfeeding discontinuation. Clinical manifestations were mainly mucocutaneous (79%), gastrointestinal (49%), respiratory (48%) and cardiovascular (21%); 25% of infants received adrenaline. Hives, hypotension and neurologic symptoms were more likely to be reported in infants than in preschool children (P = .02; P = .004; P = .002, respectively). Antihistamines and corticosteroids were more often prescribed in preschool children than in infants (P = .005; P = .025, respectively). CONCLUSION: Our study found that in infants presenting with their first food allergy, in a setting with a high rate of infant formula use, the most predominant trigger was cow's milk. As compared to older preschool children, hives, hypotonia and hypotension were more likely to be reported in infants. We believe that this represents a distinct food anaphylaxis phenotype that can further support developing the clinical anaphylaxis criteria in infants.

Evaluation of upper esophageal sphincter in benign vocal lesions.

PURPOSE: To evaluate upper esophageal sphincter (UES) activity in patients with benign glottic lesions. METHODS: Twenty-three patients with benign vocal fold (VF) lesions scheduled for manometric evaluation were enrolled as the study group (SG); 20 healthy subjects without vocal pathology or dysphagia were included as the control group (CG). UES residual, basal, relaxation time and peak pharyngeal pressures were evaluated by manometry. The reflux symptom index (RSI) and reflux finding score (RFS) were used to estimate the clinical findings of laryngopharyngeal reflux, and the voice handicap index (VHI) was measured in both groups. The patients' data were compared using the Mann-Whitney test and t test. RESULTS: The diagnoses in the SG were vocal nodules, vocal polyps, vocal cysts, sulcus vocalis, or Reinke's edema. The evaluation scores (RSI, RFS, and VHI) were significantly higher in the SG than in the CG (P < 0.05). UES basal and relaxation pressures, relaxation time, and peak pharyngeal pressures did not differ between the SG and the CG (P > 0.05). CONCLUSION: UES manometric pressure was similar in patients with VF mucosal lesions and controls. Studies involving larger populations are necessary to confirm the manometric changes in the UES and to elucidate the pathogenesis of benign VF lesions.

[The clinical and functional condition of the larynx in the patients of the elder age group presenting with chronic oedematous polypoidal laryngitis]. / Kliniko-funktsional'noe sostoianie gortani u patsientov starshei vozrastnoi gruppy s khronicheskim otechno-polipoznym laringitom.

This article was designed to report the results of the evaluation of the clinical and functional condition of the larynx in the patients of the elder age group presenting with chronic oedematous polypoidal laryngitis before and after their surgical treatment. A total of 60 patients at the age from 60 to 72 years were available for the examination; all of them had a concomitant somatic or ENT pathology. The clinical and functional conditions of the larynx in the patients of the elder age group were studied, with special reference to those suffering from chronic oedematous polypoidal laryngitis before the surgical intervention, that determined the overall clinical picture of the disease characterized in the first place by the predominance of the severe polypoid process with the combination of the organic and functional laryngeal pathology. The specific clinical and functional features of the larynx were identified after the surgical treatment that exerted the appreciable influence on the postoperative course of the disease and the duration of dysphonia. The peculiarities of postoperative laryngitis are described. Its catarrhal form was diagnosed in 42% of the patients. The strong inflammatory reaction with exudation and formation of fibrin films was documented in 58% of the patients while 83% of them exhibited formation of the functional component of dysphonia that required the application of the additional therapeutic measures for the complete restoration of the vocal function taking into consideration the age-related alteration of the larynx together with the long-term postoperative observation of the patients.

Two rare cases of laryngeal intralymphatic histiocytosis.

We report two rare cases of intralymphatic histiocytosis causing, respectively, recurrent and persistent episodes of upper airway swelling and breathing difficulties. Case 1 was a 39-year-old man who was referred with recurrent upper airway swelling causing difficulty in breathing. A direct laryngoscopy was performed under general anesthesia due to minimal effect from treatment with antibiotics and anti-oedema medication. On examination, the larynx was found to be swollen and oedematous but not inflamed. Biopsies from the aryepiglottic folds showed intralymphatic histiocytosis. The patient was extensively examined but the only abnormal finding was a low CD4 count. The breathing difficulties fluctuated during the diagnostic process and settled after a year. Case 2 was a 35-year-old man who presented with persistent laryngeal swelling. Biopsies from the epiglottis showed intralymphatic histiocytosis. Extensive investigations were performed but discovered no abnormal findings. He received CO2 laser treatment twice and the swelling decreased. Intralymphatic histiocytosis is extremely rare in upper airway pathology. It is an important differential diagnosis in patients with recurrent and chronic laryngeal swelling and dyspnoea.

Analysis of Potassium Titanyl Phosphate Laser Settings and Voice Outcomes in the Treatment of Reinke's Edema.

OBJECTIVE: Despite increased clinical utility of the 532-nm potassium titanyl phosphate (KTP) laser, no studies have examined outcomes for Reinke's edema (RE) as a function of laser parameters and initial treatment effects. Variability in delivery parameters, fiber-to-tissue distance, and immediate end-tissue effects limits universal application of existing study outcomes. We examine voice outcomes using standardized treatment classification, providing justification for laser parameter selection and immediate tissue effect in clinical use. METHODS: Retrospective review of 9 patients who underwent KTP laser treatment for RE. Demographics, RE severity, laser settings, total laser energy, and immediate tissue effects were correlated with quantified voice outcomes. RESULTS: An average of 157 joules (6-640 J) was delivered over a 0.369-second exposure time (0.1-0.9 seconds). Immediate tissue effects varied from nonablative treatment (type I and type II) to ablation without tissue removal (type III). Overall, Voice Handicap Index-10 (VHI-10) decreased by 8.23; improvement was most pronounced with type II treatments (delta VHI-10=12). No complications were encountered. CONCLUSION: Potassium titanyl phosphate laser can be safely and effectively used to improve voice in RE patients regardless of severity. This is the first study to provide detailed information on laser settings, energy delivery, and treatment effect in RE management; these results may guide clinical use of this modality, especially for novice laser surgeons.

Angiotensin converting enzyme inhibitor-related angioedema: onset, presentation, and management.

OBJECTIVE: This study aimed to determine the duration of use, presentation, and management of angiotensin converting enzyme (ACE) inhibitor-related angioedema patients at an urban academic medical center. METHODS: Retrospective chart review. RESULTS: Eighty-eight patients who presented with ACE inhibitor-related angioedema between January 1, 2012, and December 31, 2012, were identified. They presented anywhere from 1 day to 20 years after starting an ACE inhibitor. About half the patients (50.7%) presented after taking an ACE inhibitor for at least 1 year. Fifty-five patients were female (62.5%). Twenty-eight patients (31.8%) had an airway intervention with 27 intubated and 1 requiring cricothyroidotomy. Six patients were intubated after more than 1 flexible laryngoscopy. The percentage of patients with involvement of the face, lips, tongue, floor of mouth, soft palate/uvula, and larynx were 12.5%, 60.2%, 39.7%, 6.8%, 17.0%, and 29.5%, respectively. Sixty-eight percent of patients with laryngeal edema were intubated. The majority of patients were treated with a corticosteroid and H1 and H2 receptor antagonists. CONCLUSION: Angioedema can occur at any time after starting ACE inhibitor use, with nearly half occurring after 1 year of use. Laryngeal involvement occurred in a minority of patients, but most of these patients were felt to require airway protection.

Exploring the Pathophysiology of Reinke's Edema: The Cellular Impact of Cigarette Smoke and Vibration.

OBJECTIVES: To explore the isolated or combined effects of cigarette smoke extract (CSE) and vibration on human vocal fold fibroblasts (hVFF) in an in vitro setting in order to elucidate their influence in the pathophysiology of Reinke's edema (RE). STUDY DESIGN: Immortalized hVFF were exposed to CSE or control medium under static or vibrational conditions. A phonomimetic bioreactor was used to deliver vibrational patterns to hVFF over a period of 5 days. METHODS: Cytotoxicity was quantified using a lactate dehydrogenase assay. We employed reverse transcription-quantitative polymerase chain reaction, enzyme-linked immunosorbent assay, and Magnetic Luminex(R) assays (R&D Systems, Minneapolis, MN) to assess the influence on extracellular matrix production, fibrogenesis, inflammation, and angiogenesis. RESULTS: We observed significant changes induced by CSE alone (hyaluronic acid, matrix metalloproteinase 1, Interleukin-8, cyclooxygenase [COX]1, COX2, vascular endothelial growth factor [VEGF]D), as well as settings in which only the combination of CSE and vibration led to significant changes (transforming growth factor beta 1, VEGFA, VEGFC). Also, CSE-induced levels of COX2 were only significantly reduced when vibration was applied. CONCLUSION: We were able to explore the cellular effects of CSE and vibration on hVFF by employing a phonomimetic bioreactor. Whereas cigarette smoke is generally accepted as a risk factor for RE, the role of vibration remained unclear as it is difficult to study in humans. Our data showed that some genes and proteins in the pathophysiological context of RE were only affected when CSE in combination with vibration was applied.

Pathogenic Role of Reinke's Edema in Snoring and Obstructive Sleep Apnea.

OBJECTIVE: To investigate the association between vocal fold Reinke's edema, snoring, and obstructive sleep apnea. DESIGN/METHODS: Twenty-five patients diagnosed with Reinke's edema and 25 patients with normal laryngeal examination, matched according to age, gender, and body mass index were recruited for this prospective study. Demographic data included age, gender, and body mass index. All patients filled the Berlin Questionnaire, STOP-BANG Sleep Apnea Questionnaire, and the Epworth Sleepiness Questionnaire. RESULTS: Out of 25 patients with Reinke's edema, 36% had Obstructive Sleep Apnea (OSA) as evidenced by having two or more positive categories in the Berlin Questionnaire. In the control group, only 4% had OSA.The difference between the two groups was statistically significant (P value = 0.005). With respect to Epworth Sleepiness Scale and the STOP-BANG Sleep Apnea Questionnaire (P value > 0.05), there was no statistically significant difference between the two groups. CONCLUSIONS: This investigation revealed higher prevalence of snoring and obstructive sleep apnea in patients with Reinke's edema as evidenced by the Berlin Questionnaire. The caring physician should be alert to symptoms of airway obstruction for possible early intervention.

Reinke's Edema.

Reinke's edema (RE) is the polypoid degeneration of one or both vocal folds within Reinke's space. The viscoelastic properties of the mucosal folds are characteristically altered by the expansion of the subepithelial space. Most frequently, patients present with dysphonia, with women being more affected than men. The primary risk factor is tobacco use. Voice overuse and laryngopharyngeal reflux are also considered to be contributory. Although RE shares the same primary risk factor as malignancy, the risk of malignancy is low, and dysplasia is found only in 0% to 3% of cases. Treatment is focused on decrease of risk factors, such as implementation of smoking cessation, voice therapy, and reflux control. Surgical techniques aim to decrease redundant polypoid mucosa in order to improve voice and restore the glottic airway. Recurrence of RE is high.

Cigarette Smoke Exposure to Pig Larynx in an Inhalation Chamber.

OBJECTIVES: This study investigated the effects of cigarette smoke exposure on the pig larynx using an inhalation chamber. Specifically, we compared the effects of cigarette smoke exposure from either 3 cigarettes per day (3cd) or 15 cigarettes per day (15cd) for 20 days. STUDY DESIGN: In vivo prospective design. METHODS: Female pigs were exposed via an inhalation chamber to cigarette smoke (3R4F research cigarettes) from 3cd (n = 6) or 15cd (n = 6) for 20 days. Outcomes included histopathology of vocal fold and airway tissues; gene expression of interleukins, TNF-α, and VEGF; protein levels of TNF-α and IL-6; and number of coughs recorded in the chamber. RESULTS: Pigs exposed to cigarette smoke from 15cd exhibited mild vocal fold edema as compared to the 3cd group on histopathological evaluation. There was also minimal inflammation of nasal and tracheal tissue characterized by presence of more granulocytes in the 15cd group compared to the 3cd group. Cough frequency was significantly greater for the 15cd group compared to the 3cd group. CONCLUSIONS: A custom-designed large animal inhalation chamber successfully challenged pigs repeatedly, to varying levels of cigarette smoke. Future studies will combine such low levels of smoke exposure with other common challenges such as acid reflux to understand the multifactorial causation of laryngeal pathologies.

Inhalational injury and the larynx: A review.

OBJECTIVE: To review and discuss the existing research on the pathophysiology, impact and management of inhalational injury on the larynx and lower respiratory tract. DATA SOURCES: A literature search was conducted on the PubMed, MedLine, Embase, Web of Science and Google Scholar databases based on the keywords "airway burn", "inhalational injury" and "larynx". REVIEW METHODS: Inclusion criteria included English language studies containing original and review data on airway injury. Data was reported using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. CONCLUSIONS: Abnormal laryngeal and lower airway findings are common in burns patients and the incidence tends to increase with severity of the burns. Most patients with abnormal findings remain dysphonic decades after the initial injury. Larynx, the inlet to the airway, is exposed to the most intense thermal damage and highest concentration of chemical in inhalational injury. Airway injury is common and may result in long term morbidity. Healing of this tissue architecture is prolonged and different from cutaneous burn. Many patients receive prolonged intubation for medical complications that arise due to the burn injury. The degree of subglottic damage, however, is more extensive and occurs sooner compared with those without inhalational injuries. IMPLICATIONS FOR PRACTICE: With advances in acute medical and surgical management of burn and inhalational injury, airway injury is an important secondary outcome with lasting impact. Awareness of these potential complications and early involvement of medical and allied health team are important steps in improving patient care. A multi-disciplinary approach to management will optimise the short and long-term morbidity management and ultimately our patients' quality of life.

Permeability and Weibel-Palade Bodies of the Blood Vessels in the Human Vocal Fold Mucosa.

OBJECTIVES: Transendothelial exchange and permeability of the capillaries in Reinke space (the superficial layer of the lamina propria) of the vocal fold mucosa affect physiological and pathological conditions of the human vocal fold mucosa. The mechanism of permeability and Weibel-Palade bodies of the blood vessels in the human vocal fold mucosa were investigated using electron microscopy. STUDY DESIGN: Histologic analysis of the human vocal fold. METHODS: Six normal human vocal folds (three adults and three newborns) obtained from autopsy cases and three human vocal folds with Reinke edema from surgical specimens were investigated under transmission electron microscopy. RESULTS: There were three possible capillary wall transport systems related to the permeability of the blood vessels in the vocal fold mucosa: 1) Fenestra transport, plasma exuded from the capillaries into surrounding tissue via the fenestration with or without a diaphragm; 2) vesicular transport (transcellular transport via vesicles), the use of vesicles to ferry fluid and solutes across endothelial cells; and 3) junctional transport (intercellular transport), molecules passed through intercellular gaps between endothelial cells. Weibel-Palade bodies were present in the cytoplasm of endothelial cells both in adults and newborns. They were present in high numbers in the cytoplasm of endothelial cells, with intercellular transport in the vocal folds with Reinke edema. CONCLUSION: There were three types of mechanisms for the permeability of the blood vessels in the human vocal fold mucosa. Some physiologically active substances, such as histamine produced by Weibel-Palade bodies, may adversely influence the permeability of the blood vessels. LEVEL OF EVIDENCE: NA. Laryngoscope, 2588-2592, 2018.

"Cold-Steel" Phonosurgery of Reinke Edema Evaluated by the Multidimensional Voice Program.

OBJECTIVES: "Cold-steel" phonosurgery (PS) of Reinke edema is challenging, as the delicate structures of the vocal folds are difficult to preserve. This study aimed to evaluate the results of PS using the Multidimensional Voice Program (MDVP) . MATERIALS AND METHODS: From 2003 to 2007, 76 consecutive patients with Reinke edema were treated with PS for the first time. Reliable MDVP data were available in 37 female patients with both pre- and postoperative values in 14 patients. Voice quality and outcome after PS were evaluated by jitter, shimmer, soft phonation index, and fundamental frequency (f0) using MDVP, videostroboscopy, and a five-step voice outcome score. RESULTS: In the 14 patients, the mean f0 increased from 172 to 222 (P = 0.01), and jitter decreased from 2.03 to 1.17 (P = 0.04) 3 months postoperatively. Vocal fold grading based on videostroboscopy correlated significantly with jitter (P = 0.01). Patients with high preoperative values of jitter, shimmer, or soft phonation index had larger reductions than those with normal values. All had a postoperative reduction of the edemas. The mean voice outcome score increased postoperatively. None of the 37 patients reported complications, but seven patients were reoperated. Preoperatively, 95% of the 37 patients were smokers and only 9 (24%) changed smoking habits. Pre- or postoperative voice therapy was used in 23 (62%) patients. CONCLUSIONS: f0 and jitter by MDVP adequately reflected the postoperative voice improvement and reduction of the edema. Removal of large amounts of edematous tissue, many years of vocal abuse, and unchanged smoking habits may prevent optimal results.

Hyaluronidase Injection in the Vocal Folds for Vocal Hemorrhage, Reinke Edema, and Hyaluronic Acid Overinjection: A Novel Application in the Larynx.

Hyaluronidase (HAase) injection into the vocal folds is an off-label use of an enzyme for liquefaction of hyaluronic acid (HA). HAase injection was performed in 14 cases in 13 patients. Office and operative injections of HAase were performed. The indications were five cases of overinjection of HA, six cases of Reinke edema and polypoid corditis, and three cases of acute vocal hemorrhage with early fusiform polyp formation. All the patients tolerated the HAase without complications. Significant voice improvements were noted between pre- and postinjection procedures as evaluated by a self-rating of voice by the Voice Handicap Index-10. A marked decrement in the mass on the side of the injection of HAase was noted in all groups successfully injected upon viewing by videostroboscopy. HAase prevented an additional operative phonosurgery in 10 patients. In conclusion, HAase injection can be used in the vocal folds with good effect in patients. The indications are polypoid corditis with overproduction of HA, acute vocal hemorrhage, and correction of iatrogenic HA overinjection.

Laryngopharyngeal abnormalities in hospitalized patients with dysphagia.

OBJECTIVES: To determine the prevalence of laryngopharyngeal (LP) abnormalities in hospitalized patients with dysphagia referred for flexible endoscopic evaluation of swallowing (FEES). STUDY DESIGN: Retrospective, blinded review by two otolaryngologists of 100 consecutive FEES studies performed and video-recorded by a speech-language pathologist (SLP). METHODS: Two otolaryngologists reviewed videos of 100 consecutive FEES studies on hospitalized patients with dysphagia for the presence of abnormal LP findings. RESULTS: Sixty-one male and 38 female patients comprised the hospital dysphagia cohort. The mean age was 62. One subject could not be evaluated because of the severity of the retained secretions, leaving 99 subjects in the cohort. Seventy-six percent had been previously intubated, with a mean intubation duration of 13 days. The overall prevalence of abnormal LP findings was 79%. Forty-five percent of the patients presented with two or more findings, which included arytenoid edema (33%), granuloma (31%), vocal fold paresis (24%), mucosal lesions (17%), vocal fold bowing (14%), diffuse edema (11%), airway stenosis (3%), and ulcer (6%). There was a significant difference in LP findings between those individuals who had or had not been intubated. CONCLUSIONS: Hospitalized patients with dysphagia are at high risk for LP abnormalities, particularly if they have been intubated, and may benefit from either 1) an initial joint examination by the SLP and otolaryngologist or 2) an otolaryngologist's review of the recorded examination conducted by the SLP. Such otolaryngology involvement could identify airway stenosis patients at an earlier stage, initiate granuloma treatment sooner, enable earlier biopsy of unexpected lesions, and allow follow-up of mucosal and neuromuscular findings that do not respond to medical management.

Videostroboscopic characteristics of young adult female smokers vs. nonsmokers.

OBJECTIVES: The purpose of this study was to provide a foundation of information concerning the early effects of smoking on the laryngeal structures and phonatory physiology of young adult women using videostroboscopy. STUDY DESIGN: Cross-sectional, observational. METHODS: Subjects were 34 female nonsmokers and 30 female smokers (Total N=64) between the ages of 18 and 30 years of age. For the purposes of this study, a smoker was defined as any subject who, at the time of this study, had smoked at least two cigarettes per day for at least 1 year. All subjects in the nonsmoker category were those who, at the time of this study, did not smoke and who had not smoked for at least 5 years before the study. Videostroboscopic evaluations were rated by experienced judges on various parameters describing the structure and function of the laryngeal mechanism during comfortable pitch and loudness phonations. RESULTS: Results showed significant relationships between smoking and the increased presence of edema, erythema, and abnormal laryngeal color. In addition, smokers were observed to have significantly more occurrences of abnormal phase symmetry and increased glottal gap size during the closed phase of phonation. Glottal gap size was significantly correlated with the number of cigarettes smoked in the lifetime. CONCLUSIONS: The findings of increased erythema and edema in this study are consistent with previous descriptions of the effects of smoking on laryngeal structures, whereas our observations regarding glottal gap size and phase symmetry are unique contributions derived from the stroboscopic method. The results of this study indicate that observable signs of laryngeal irritation and disturbed phonatory physiology occur even in young adults with relatively brief smoking habits.

Voice analysis of patients with diverse types of Reinke's edema and clinical use of electroglottographic measurements.

CONCLUSIONS: Reinke's edema shows a variety of clinical patterns and differences in voice analysis depending on its type. Electroglottographic measurements help to objectively assess the severity of edema and voice quality before and after surgery. OBJECTIVES: Reinke's edema manifests various clinical findings and different voice characteristics depending on the degree of swelling and the severity of voice impairment. The aim of this study was to compare the aerodynamic, acoustic and electroglottographic parameters for the different types of Reinke's edema according to its morphological, perceptual and histopathological classifications, and to assess voice quality in patients with Reinke's edema before and after laryngomicrosurgery. We also aimed to determine which parameter was most associated with the improvement in postoperative voice quality and to investigate the clinical usefulness of electroglottographic analysis in Reinke's edema. MATERIAL AND METHODS: The clinical and voice records of 61 patients with Reinke's edema were reviewed. All the patients were classified according to stroboscopic findings (Yonekawa's classification), perceptual grade and histopathological findings. Voice analysis of the perceptual, acoustic, aerodynamic and electroglottographic measurements was carried out using various classifications, and the voices of 23 patients who underwent laryngomicrosurgery were evaluated 2 months after surgery. Furthermore, the voices of 30 normal speakers (controls) were recorded and analyzed. RESULTS: The fundamental frequency (FxM) of Yonekawa Type III was significantly lower than those of the other types of Reinke's edema, and the SD of the FxM, the percentage irregularity of the FxM (CFx) and the percentage irregularity of the amplitude were larger than those of the other types of Reinke's edema. The closed quotient was significantly higher in Yonekawa Type III. In addition, the mean flow rate (MFR), maximum phonation time and harmonics:noise ratio (HNR) differed significantly among the different types of Reinke's edema. The postoperative results showed an increase in the FxM and an improvement in the MFR, subglottic pressure, shimmer and HNR. Correlation analysis showed that jitter, the HNR, the mean closed quotient and the irregularity of the frequency were the parameters that had the best correlation with improvement in postoperative voice quality.

[Influence of treatment of inhaled corticosteroids on the function of the larynx in asthmatic patients]. / Wplyw glikokortykosteroidów wziewnych na czynnosc fonacyjna krtani u chorych na astme.

UNLABELLED: The objective of the study was to examine influence of inhaled glycocorticosteroids on phoniatric function of the larynx in patients suffering from asthma. MATERIAL AND METHODS: Thirty minutes after the administration and long-term therapy effect of the inhaled glycocorticosteroids on local condition of the phoniatric organ was assessed in 15 patients with recently diagnosed bronchial asthma. The diagnostics of asthma included: subjective and objective examination, prick tests, spirometry, total IgE and histamine test for bronchial hyperactivity. Evaluation of voice function was implemented subjectively and objectively with use of videolaryngostroboscopy (VLSS). Acoustic assessment of voice was also performed. RESULTS: Administration of glycocorticosteroids as inhaled discs resulted in incidents of cough, mouth and throat dryness, sensation of polydipsia and skin inflammation around the mouth. Occasionally, hoarseness and discomfort in the larynx area were noted. On long-term administration, dysphonia, hoarseness and voice fatigue due to dysfunction of innermost larynx muscles, particularly vocal fold adductors. After 30 minutes of the glycocorticosteroid administration in patients with recently diagnosed asthma, irritation of the pharynx and larynx mucosa was recorded. CONCLUSION: The long-term treatment with inhaled glycocorticosteroids resulted in myopathy of proper muscles of the larynx.
