Abstract
Objective: Exercised induced laryngeal obstruction (EILO) is an important cause of exertional dyspnea. The diagnosis rests on visual judgement of relative changes of the laryngeal inlet during continuous laryngoscopy exercise (CLE) tests, but we lack objective measures that reflect functional consequences. We aimed to investigate repeatability and normal values of trans-laryngeal airway resistance measured at maximal intensity exercise.Methods: Thirty-one healthy non-smokers without exercise related breathing problems were recruited. Participants performed two CLE tests enabling verified positioning of two pressure sensors, one at the tip of the epiglottis (supraglottic) and one by the fifth tracheal ring (subglottic). Airway pressure and flow data were continuously collected breath-by-breath and used to calculate trans-laryngeal resistance at peak exercise. Laryngeal obstruction was assessed according to a standardised CLE-score system.Results: Data from 26 participants (16 females) with two successful tests and equal CLE scores on both test-sessions were included in the trans-laryngeal resistance repeatability analyses. The coefficient of repeatability (CR) was 0.62 cmH2O·L−1·s−1, corresponding to a CR% of 21%. Mean (sd) trans-laryngeal airway resistance (cmH2O·L−1·s−1) in participants with no laryngeal obstruction (n=15) was 2.88 (0.50) in females and 2.18 (0.50) in males. Higher CLE scores correlated with higher trans-laryngeal resistance in females (r=0.81, p<0.001).Conclusions: This study establishes trans-laryngeal airway resistance obtained during exercise as a reliable parameter in respiratory medicine, opening the door for more informed treatment decisions and future research on the role of the larynx in health and disease.

Abstract
PURPOSE Exercise-induced bronchoconstriction (EIB) and exercise-induced laryngeal obstruction (EILO) are two disorders commonly considered when athletes complain of exertional dyspnea. They are highly different but often confused. We aimed to address this diagnostic challenge and its consequences in elite athletes. METHODS We included all athletes competing at national or international level, referred to our institution for workup for EILO during 2013-2016. We diagnosed EILO from video-recorded laryngoscopy performed during maximal cardiopulmonary treadmill exercise (CLE-test). Symptoms and previous diagnostic evaluations were obtained from referral letters and chart reviews. RESULTS EILO was diagnosed in 73/101 referred athletes, of whom 70/73 had moderate/severe supraglottic obstruction and 3/73 had primarily glottic obstruction with only minor supraglottic involvement. Of the 73 athletes with EILO, we were able to identify objective tests for asthma in 55 participants, of whom 22 had findings supporting asthma. However, 58/73 had used asthma therapy at some time previously, with current use in 28. Only three reported that asthma medication had improved their exercise related breathing problems, two of whom with tests confirming asthma. Treatment for EILO improved breathing problems in all but four. CONCLUSIONS Objective testing verified EILO in most of the referred athletes. EILO coexisting with asthma was common, and large proportions had used asthma medication; however, few reported effect on exercise related breathing problems. Unexplained persistent exertional dyspnoea must not lead to indiscriminate escalation of asthma treatment, but instead incite investigation for EILO, either as a co-morbidity or as a differential diagnosis.

Abstract
BACKGROUND Exercise-induced laryngeal obstruction (EILO) is a common cause of exertional breathing problems in young individuals, caused by paradoxical inspiratory adduction of laryngeal structures, and diagnosed by continuous visualization of the larynx during high-intensity exercise. Empirical data suggest that EILO consists of different subtypes, possibly requiring different therapeutic approaches. Currently applied treatments do not rest on randomized controlled trials, and international guidelines based on good evidence can therefore not be established. This study aims to provide evidence-based information on treatment schemes commonly applied in patients with EILO. METHODS AND ANALYSIS Consenting patients consecutively diagnosed with EILO at Haukeland University Hospital will be randomized into four non-invasive treatment arms, based on promising reports from non-randomized studies: (A) standardized information and breathing advice only (IBA), (B) IBA plus inspiratory muscle training, (C) IBA plus speech therapy, and (D) IBA plus inspiratory muscle training and speech therapy. Differential effects in predefined EILO subtypes will be addressed. Patients failing the non-invasive approach and otherwise qualifying for surgical treatment by current department policy will be considered for randomization into (E) standard or (F) minimally invasive laser supraglottoplasty or (G) no surgery. Power calculations are based on the main outcomes, laryngeal adduction during peak exercise, rated by a validated scoring system before and after the interventions. ETHICS AND DISSEMINATION The study will assess approaches to EILO treatments that despite widespread use, are insufficiently tested in structured, verifiable, randomized, controlled studies, and is therefore considered ethically sound. The study will provide knowledge listed as a priority in a recent statement issued by the European Respiratory Society, requested by clinicians and researchers engaged in this area, and relevant to 5-7% of young people. Dissemination will occur in peer-reviewed journals, at relevant media platforms and conferences, and by engaging with patient organizations and the healthcare bureaucracy.

Abstract
Purpose Exercise-induced laryngeal obstruction (EILO) is relatively common in young people. Treatment rests on poor evidence; however, inspiratory muscle training (IMT) has been proposed a promising strategy. We aimed to assess laryngeal outcomes shortly after IMT, and to compare self-reported symptoms with a control group 4–6 years later. Methods Two groups were retrospectively identified from the EILO-register at Haukeland University Hospital, Norway; one group had received only information and breathing advice (IBA), and another additionally IMT (IBA + IMT). At diagnosis, all participants performed continuous laryngoscopy during exercise (CLE), with findings split by glottic and supraglottic scores, and completed a questionnaire mapping exercise-related symptoms. After 2–4 weeks, the IBA + IMT-group was re-evaluated with CLE-test. After 4–6 years, both groups were re-assessed with a questionnaire. Results We identified 116 eligible patients from the EILO-register. Response rates after 4–6 years were 23/58 (40%) and 32/58 (55%) in the IBA and IBA + IMT-group, respectively. At diagnosis, both groups rated symptoms similarly, but laryngeal scores were higher in the IBA + IMT-group (P = 0.003). After 2–4 weeks, 23/32 in the IBA + IMT-group reported symptom improvements, associated with a decrease of mainly glottic scores (1.7–0.3; P < 0.001), contrasting unchanged scores in the 9/32 without symptom improvements. After 4–6 years, exercise-related symptoms and activity levels had decreased to similar levels in both groups, with no added benefit from IMT; however, full symptom resolution was reported by only 8/55 participants. Conclusion Self-reported EILO symptoms had improved after 4–6 years, irrespective of initial treatment. Full symptom resolution was rare, suggesting individual follow-up should be offered.

Abstract
Background: Policies assigning low-priority patients treatment delays for care, in order to make room for patients of higher priority arriving later, are common in secondary healthcare services today. Alternatively, each new patient could be granted the first available appointment. We aimed to investigate whether prioritisation can be part of the reason why waiting times for care are often long, and to describe how departments can improve their waiting situation by changing away from prioritisation. Methods: We used patient flow data from 2015 at the Department of Otorhinolaryngology, Haukeland University Hospital, Norway. In Dynaplan Smia, Dynaplan AS, dynamic simulations were used to compare how waiting time, size and shape of the waiting list, and capacity utilisation developed with and without prioritisation. Simulations were started from the actual waiting list at the beginning of 2015, and from an empty waiting list (simulating a new department with no initial patient backlog). Results: From an empty waiting list and with capacity equal to demand, waiting times were built 7 times longer when prioritising than when not. Prioritisation also led to poor resource utilisation and short-lived effects of extra capacity. Departments where prioritisation is causing long waits can improve their situation by temporarily bringing capacity above demand and introducing "first come, first served" instead of prioritisation. Conclusion: A poor appointment allocation policy can build long waiting times, even when capacity is sufficient to meet demand. By bringing waiting times down and going away from prioritisation, the waiting list size and average waiting times at the studied department could be maintained almost 90% below the current level – without requiring permanent change in the capacity/demand ratio.

Abstract
Dynamic obstructions of the larynx are a set of disorders that occur during exercise in equines and humans. There are a number of similarities in presentation, diagnosis, pathophysiology and treatment. Both equines and humans present with exercise intolerance secondary to dyspnea. During laryngoscopy at rest, the larynx appears to function normally. Abnormalities are only revealed during laryngoscopy at exercise, seemingly triggered by increased ventilatory demands, and quickly resolve after cessation of exercise. Lower airway disease (asthma being the most prevalent condition), cardiac disease and lack of fitness are the major differentials in both species. Laryngoscopic examination during exercise should be performed from rest to peak exertion to allow for a comprehensive diagnosis, including where the airway collapse begins, and thereafter how it progresses. Dynamic disorders with most visual similarity between humans and equines are: aryepiglottic fold collapse (both species); equine dynamic laryngeal collapse (DLC) relative to some forms of human combined supraglottic/glottic collapse; and epiglottic retroversion (both species). Quantitative grading techniques, such as airway pressure measurement, that have proven effective in veterinary research are currently being piloted in human studies. Conditions that appear visually similar are treated in comparable ways. The similarities of anatomy and certain types of dynamic collapse would suggest that the equine larynx provides a good model for human upper respiratory tract obstruction during exercise. Thus, close collaboration between veterinarians and medical personal may lead to further advancements in understanding pathophysiologic processes, and enhance the development of improved diagnostic tests and treatments that will benefit both species.

Abstract
Introduction: Exercise induced laryngeal obstruction (EILO) is relatively common in adolescents, with symptoms often confused with exercise induced asthma. EILO often starts with medial or inward rotation of supraglottic structures of the larynx, whereas glottic adduction appears as a secondary phenomenon in a majority. Therefore, surgical treatment (supraglottoplasty) is used in thoroughly selected and highly motivated patients with pronounced symptoms and severe supraglottic collapse. Aim: To investigate efficacy and safety of laser supraglottoplasty as treatment for severe supraglottic EILO by retrospective chart reviews. Methods: The EILO register at Haukeland University Hospital, Bergen, Norway was used to identify patients who had undergone laser supraglottoplasty for severe supraglottic EILO, verified by continuous laryngoscopy exercise (CLE) test, during 2013–2015. Laser incision in both aryepiglottic folds anterior to the cuneiform tubercles and removal of the mucosa around the top was performed in general anesthesia. Outcomes were questionnaire based self-reported symptoms, and laryngeal obstruction scored according to a defined scheme during a CLE-test performed before and after surgery. Results: Forty-five of 65 eligible patients, mean age 15.9 years, were included. Post-operatively, 38/45 (84%) patients reported less symptoms, whereas CLE-test scores had improved in all, of whom 16/45 (36%) had no signs of obstruction. Most improvements were at the supraglottic level, but 21/45 (47%) also improved at the glottic level. Two of 65 patients had complications; self-limiting vocal fold paresis and scarring/shortening of plica ary-epiglottica. Conclusion: Supraglottoplasty improves symptoms and decreases laryngeal obstruction in patients with severe supraglottic EILO, and appears safe in highly selected cases.

Abstract
Objectives/Hypothesis To determine if simultaneous tracheal and supraglottic pressure measurement performed during a continuous laryngoscopy exercise (CLE) test is possible, tolerable, and feasible, and if so, whether measurements can be used to determined airflow resistance over the larynx, thus providing an objective outcome measure for the CLE test, the gold standard for diagnosing exercise‐induced laryngeal obstruction. Study Design Explorative descriptive clinical study. Methods A CLE test was performed with the addition of two pressure sensors (Mikro‐Cath 825‐0101; Millar, Houston, TX) placed at the epiglottic tip and at the fifth tracheal ring. To place sensors, laryngeal anesthesia and a channel scope were required. Tolerability and feasibility was determined by a Likert score and subjective indication from subjects and operators. Adjustments to the technique were made to increase tolerability. The pressure data were continuously collected and analyzed for artifacts, drifts, frequency response, and used with flow data to calculate translaryngeal resistance. Results All subjects (n = 7) completed all procedures. Two main areas of concern were identified regarding tolerability: application of topical anesthesia to the larynx and nasal discomfort due to the added diameter of the laryngoscope. Protocol adjustments improved both. Pressure data were obtained from all procedures in all subjects, were consistent, and followed physiological trends. Conclusions Continuous measurement of the translaryngeal pressure gradient during a CLE test is possible, feasible, and tolerable. A CLE test with direct measurement of the translaryngeal pressure gradient might become a valuable tool in the objective assessment of respiratory function, and normal values should be established in health and disease.

Abstract
Background Exercise-induced laryngeal obstruction (EILO) is common in athletes and presents with dyspnoea, chest tightness, inspiratory stridor and sometimes panic reactions. The evidence for conservative treatment is weak, but case reports suggest effects from inspiratory muscle training (IMT). We aimed to explore effects from IMT used in athletes with EILO. Method Twenty-eight athletes, mean age 16.4 years, diagnosed with EILO at our clinic, participated in a 6-week treatment programme, using a resistive flow-dependent IMT device (Respifit S). Four athletes competed at international level, 13 at national and 11 at regional levels. Video-recorded continuous transnasal flexible laryngoscopy was performed from rest to peak exercise (continuous laryngoscopy exercise (CLE) test) and scored before and 2–4 weeks after the training period. Ergospirometric variables were obtained from this CLE set-up. Lung function was measured according to guidelines. Symptom scores and demographic variables were obtained from a questionnaire. Results After the treatment period, symptoms had decreased in 22/28 (79%) participants. Mean overall CLE score had improved after treatment (p<0.001), with the scores becoming normal in five athletes but worse in two. Most of the improvement was explained by changes at the glottic laryngeal level (p=0.009). Ergospirometric variables revealed significantly higher peak minute ventilation explained by higher tidal volumes and were otherwise unchanged. Conclusion This explorative study underlines the heterogeneous treatment response of EILO and suggests that IMT may become an efficient conservative treatment tool in subgroups, possibly contributing to better control of the vocal folds. The signals from this study should be tested in future controlled interventional studies.

Abstract
OBJECTIVES Patients with voice-related disorders are ideally treated by a multidisciplinary team. Acoustic voice analysis and patient-reported outcome measures are recommended parts of the clinical assessment. The present paper aims at further documenting the importance of acoustic voice analyses, maximum phonation time (MPT) and Voice Handicap Index (VHI) into clinical investigations. STUDY DESIGN The participants (N = 80 larynx cancer, N = 32 recurrent palsy, N = 23 dysfunctional, N = 75 degenerative/inflammation (N = 19 various excluded)) were included consecutively at the outpatient laryngology clinic at Haukeland University Hospital. In addition, a control group of 98 healthy subjects were included. METHOD Voice samples, MPT, and the VHI scores in addition to standard clinical information were obtained. Acoustic analyses were performed from these samples determining level of jitter, shimmer and Noise-to-Harmonic ratio (NHR) as well as analyzing frequency of a prolonged vowel. RESULTS Jitter, shimmer, and NHR scores correlated strongly (r ≈ 0.8; P < 0.001) to each other. By Analysis of Variance analyses, we have determined significant dependence on diagnostic group analyzing all the obtained acoustic scores (all P < 0.001). All patient groups but the dysfunctional group scored to some extent worse than the control group (mostly at P < 0.001). In addition, jitter scores from dysfunction group were lower than recurrent palsy group (P < 0.05) and shimmer scores were lower among dysfunctional than the cancer group (P < 0.05). Regarding NHR the cancer patients scored higher than the degenerative/inflammatory group (P < 0.05). The cancer group scored with longer MPT than the degenerative/inflammatory (P < 0.001) and recurrent palsy groups (P < 0.05). CONCLUSION Among larynx disease patients acoustic and MPT analyses segregated with all determined analyses between patients and control conditions except the dysfunctional group, but also to some extent between various patient groups. VHI scores correlated to jitter, shimmer and NHR scores among cancer and degenerative/inflammatory disease patients. Acoustic analyses potentially add information useful to laryngological patient studies.

Abstract
Inducible laryngeal obstruction (ILO) describes an inappropriate, transient, reversible narrowing of the larynx in response to external triggers. ILO is an important cause of a variety of respiratory symptoms and can mimic asthma. Current understanding of ILO has been hampered by imprecise nomenclature and variable approaches to assessment and management. A task force of the European Respiratory Society (ERS) and European Laryngological Society (ELS) was thus set up to address this, and to identify research priorities.A literature search identified relevant articles published until June 2016, using all identifiable terms for ILO, although including only articles using laryngoscopy. In total, 172 out of 252 articles met the inclusion criteria, summarised in sections on diagnostic approach, aetiology, comorbidities, epidemiology and treatment. The consensus taxonomy published by ERS, ELS and the American College of Chest Physicians (ACCP) in 2015 is used throughout this statement.We highlight the high prevalence of ILO and the clinical impact for those affected. Despite recent advances, most aspects of this condition unfortunately remain incompletely understood, precluding firm guidance. Specifically, validated diagnostic and treatment algorithms are yet to be established, and no randomised control studies were identified in this search; hence we also make recommendations for future research.

Abstract
BACKGROUND Most patients with amyotrophic lateral sclerosis (ALS) are treated with mechanical insufflation-exsufflation (MI-E) in order to improve cough. This method often fails in ALS with bulbar involvement, allegedly due to upper-airway malfunction. We have studied this phenomenon in detail with laryngoscopy to unravel information that could lead to better treatment. METHODS We conducted a cross-sectional study of 20 patients with ALS and 20 healthy age-matched and sex-matched volunteers. We used video-recorded flexible transnasal fibre-optic laryngoscopy during MI-E undertaken according to a standardised protocol, applying pressures of ±20 to ±50 cm H2O. Laryngeal movements were assessed from video files. ALS type and characteristics of upper and lower motor neuron symptoms were determined. RESULTS At the supraglottic level, all patients with ALS and bulbar symptoms (n=14) adducted their laryngeal structures during insufflation. At the glottic level, initial abduction followed by subsequent adduction was observed in all patients with ALS during insufflation and exsufflation. Hypopharyngeal constriction during exsufflation was observed in all subjects, most prominently in patients with ALS and bulbar symptoms. Healthy subjects and patients with ALS and no bulbar symptoms (n=6) coordinated their cough well during MI-E. CONCLUSIONS Laryngoscopy during ongoing MI-E in patients with ALS and bulbar symptoms revealed laryngeal adduction especially during insufflation but also during exsufflation, thereby severely compromising the size of the laryngeal inlet in some patients. Individually customised settings can prevent this and thereby improve and extend the use of non-invasive MI-E.

Abstract
OBJECTIVES Congenital laryngomalacia (CLM) is the major cause of stridor in infants. Most cases are expected to resolve before 2 years of age, but long-term respiratory prospects are poorly described. We aimed to investigate if CLM was associated with altered laryngeal structure or function in later life. METHODS Twenty of 23 (87%) infants hospitalised at Haukeland University Hospital during 1990-2000 for CLM without comorbidities and matched controls were assessed at mean age 13 years. Past and current respiratory morbidity was recorded in a questionnaire, and spirometry performed according to standard quality criteria. Laryngoscopy was performed at rest and continuously throughout a maximal treadmill exercise test (continuous laryngoscopy exercise test (CLE-test)), and scored and classified in a blinded fashion according to preset criteria. RESULTS In the CLM group, laryngeal anatomy supporting CLM in infancy was described at rest in nine (45%) adolescents. Eleven (55%) reported breathing difficulties in relation to exercise, of whom 7 had similarities to CLM at rest and 10 had supraglottic obstruction during CLE-test. Overall, 6/20 had symptoms during exercise and similarities to CLM at rest and obstruction during CLE-test. In the control group, one adolescent reported breathing difficulty during exercise and two had laryngeal obstruction during CLE-test. The two groups differed significantly from each other regarding laryngoscopy scores, obtained at rest and during exercise (p=0.001 or less). CONCLUSIONS CLM had left footprints that increased the risk of later exercise-induced symptoms and laryngeal obstruction. The findings underline the heterogeneity of childhood respiratory disease and the importance of considering early life factors.

Abstract
Individuals reporting episodes of breathing problems caused by re-occurring variable airflow obstructions in the larynx have been described in an increasing number of publications, with more than 40 different terms being used without consensus on definitions. This lack of an international consensus on nomenclature is a serious obstacle for the development of the area, as knowledge from different centres cannot be matched, pooled or readily utilised by others. Thus, an international Task Force has been created, led by the European Respiratory Society/European Laryngological Society/American College of Chest Physicians. This review describes the methods used to reach an international consensus on the subject and the resulting nomenclature, the 2013 international consensus conference nomenclature.

Abstract
The current follow-up study concerning the supraglottic type of exercise-induced laryngeal obstruction (EILO) was performed to reveal the natural history of supraglottic EILO and compare the symptoms, as well as the laryngeal function in conservatively versus surgically treated patients. A questionnaire-based survey was conducted 2-5 years after EILO was diagnosed by a continuous laryngoscopy exercise (CLE) test in 94 patients with a predominantly supraglottic obstruction. Seventy-one patients had been treated conservatively and 23 with laser supraglottoplasty. The questionnaire response rate was 70 and 100% in conservatively treated (CT) and surgically treated (ST) patients, respectively. A second CLE test was performed in 14 CT and 19 ST patients. A visual analogue scale on symptom severity indicated improvements in both the groups, i.e. mean values (± standard deviations) declined from 73 (20) to 53 (26) (P < 0.001) in the CT group and from 87 (26) to 25 (27) (P < 0.001) in the ST group. At follow-up, ST patients reported lower scores regarding current level of complaints, and higher ability to perform exercise, as well as to push themselves physically, all compared to CT patients (P < 0.001). CLE scores were normalized in 3 of 14 (21%) CT and 16 of 19 (84%) ST patients (Z = -3.6; P < 0.001). In conclusion, symptoms of EILO diagnosed in adolescents generally decreased during 2-5 years follow-up period but even more after the surgical treatment. Patients with supraglottic EILO may benefit from supraglottoplasty both as to laryngeal function and symptom relief.

Abstract
The head and neck squamous cell carcinoma microenvironments contain many immune cells and their secretory products. Many of these cells belong to the mononuclear phagocyte system. The aim of this review is to study the interactions between mononuclear phagocytes and head and neck squamous cell carcinoma tissue. The role of inflammation in tumours and the cytokine interleukin-6 will be highlighted. Future therapy strategies in the treatment of head and neck cancer might be directed towards mononuclear phagocytes and their cytokine production.

Abstract
Variable obstruction to airflow at the laryngeal level may cause respiratory distress during exercise. The Continuous Laryngoscopy Exercise (CLE)-test enables direct visualization of the larynx during ongoing exercise. The aims of this study were to establish a scoring system for laryngeal obstruction as visualized during the CLE-test as well as to assess reliability and validity of this scoring system. Continuous video recording of the larynx was performed in parallel with continuous video recording of the upper part of the body, and recording of breath sounds in 80 patients and 20 symptom-negative volunteers, running on a treadmill to respiratory maximal tolerable distress or exhaustion. Each participant scored the degree of symptoms during exercise. The scoring system contains four sub-scores, each graded from 0 to 3. Two independent laryngologists, blinded to clinical data, scored the video recordings of the larynx twice. The proportion of inter- and intra-observer agreement (equal scores) for each sub-score through these four sessions varied between 70 and 100% (weighted kappa values varied from 0.49 to 1.00 correspondingly). A positive correlation was found between CLE-test sum score and symptom score (rho = 0.75, P < 0.001). There was a significant difference in CLE-test sum score between patients (3.34 +/- 1.34) and volunteers (0.65 +/- 0.66) (P < 0.001). The single CLE-test sub-score that correlated most strongly with symptom score was glottic adduction at maximal effort (rho = 0.75, P < 0.001). The presented scoring system is reliable and valid, and we suggest that it can be used when laryngeal function during exercise is evaluated.

Abstract
Background This study was performed in order to determine whether monocyte in vitro function is associated with presence, stage and prognosis of head and neck squamous cell carcinoma (HNSCC) disease. Methods Prospective study describing outcome, after at least five years observation, of patients treated for HNSCC disease in relation to their monocyte function. Sixty-five patients with newly diagnosed HNSCC and eighteen control patients were studied. Monocyte responsiveness was assessed by measuring levels of monocyte in vitro interleukin (IL)-6 and monocyte chemotactic peptide (MCP)-1 secretion after 24 hours of endotoxin stimulation in cultures supplied either with 20% autologous serum (AS) or serum free medium (SFM). Survival, and if relevant, cause of death, was determined at least 5 years following primary diagnosis. Results All patients, as a group, had higher in vitro monocyte responsiveness in terms of IL-6 (AS) (t = 2.03; p < 0.05) and MCP-1 (SFM) (t = 2.49; p < 0.05) compared to controls. Increased in vitro monocyte IL-6 endotoxin responsiveness under the SFM condition was associated with decreased survival rate (Hazard ratio (HR) = 2.27; Confidence interval (CI) = 1.05–4.88; p < 0.05). The predictive value of monocyte responsiveness, as measured by IL-6, was also retained when adjusted for age, gender and disease stage of patients (HR = 2.67; CI = 1.03–6.92; p < 0.05). With respect to MCP-1, low endotoxin-stimulated responsiveness (AS), analysed by Kaplan-Meier method, predicted decreased survival (χ = 4.0; p < 0.05). Conclusion In HNSCC patients, changed monocyte in vitro response to endotoxin, as measured by increased IL-6 (SFM) and decreased MCP-1 (AS) responsiveness, are negative prognostic factors.

Abstract
Conclusion. Tumour-associated macrophages (TAMs) in head and neck squamous cell carcinomas (HNSCCs) secrete interleukin 6 (IL-6) and monocyte chemotactic protein (MCP-1) that can be down-regulated by L-leucine-methylester (LLME); however, there is no qualitative difference between function of TAMs and tissue macrophages in mucosa as measured by IL-6 and MCP-1 secretion. Objectives. TAMs play an important role in the interaction with tumour cells in malignant tumours. The cells in the tumours that are the main sources of the various signal substances need to be further elucidated. The aim of this investigation was to reveal whether TAMs in HNSCCs secrete IL-6 and MCP-1. These cytokines influence tumour cell growth and macrophage influx in tumours, respectively. Materials and methods. In order to inhibit macrophage function in F-spheroids, in some experiments the tissue fragments were initially incubated with LLME, a substance that selectively inhibits function of phagocytes. IL-6 and MCP-1 secretion from untreated F-spheroids was compared to cytokine secretion from LLME-treated F-spheroids as measured by ELISA. Results. LLME did not affect the viability of F-spheroids and reduced IL-6 and MCP-1 secretion from monocyte-derived macrophages in vitro. F-spheroids from LLME-treated tissue fragments showed lower IL-6 and MCP-1 secretion compared with F-spheroids from tissue fragment untreated with LLME.

Abstract
A method for combined ergo-spirometry and continuous laryngeal inspection during exercise, entitled continuous laryngoscopy exercise test (CLE-test) has been developed in order to study airway obstruction at the laryngeal level during exercise. The aim of the study was to apply the CLE-test on patients experiencing respiratory distress during exercise in order to reveal the usefulness of the CLE-test both as a diagnostic tool in the selection of patients for surgery and in evaluation of treatment effects postoperatively. Until now, 81 patients with a history of exercise-induced stridor have undergone the CLE-test. Ten of these patients were selected for surgical treatment based on the severity of symptoms and their motivation for treatment. All ten patients underwent endoscopic supraglottoplasty (ES), with laser incision in both aryepiglottic folds anterior to the cuneiform cartilages and removal of the mucosa around the top of the tubercles. Each patient was examined by the CLE-test before and 3 months after surgery. Eight patients felt subjectively that their breathing capacity during exercise was improved. When pre- and postoperative ergo-spirometry evaluations were compared, increased peak oxygen consumption was observed in four out of ten patients and better maximal minute ventilation in seven out of ten. Postoperative evaluation of the laryngeal images showed less prominent aryepiglottic folds. The typical adduction of the supraglottic structures concomitant with inspiratory stridor found preoperatively was not present in any of the patients during exercise postoperatively. The ES procedure is an efficient surgical treatment for exercise-induced laryngeal supraglottic obstruction and the CLE-test eases the selection of patients for surgery and facilitates the evaluation of treatment effects.

Abstract
CONCLUSIONS The results indicate that a high level of peripheral blood (PB) T-lymphocyte activation in vivo predicts impaired prognosis with and without adjustment for TNM stage in head and neck squamous cell carcinoma (HNSCC). OBJECTIVE To determine if PB T-lymphocyte activation in vivo is associated with the presence of, stage of and prognosis of HNSCC. MATERIALS AND METHODS Sixty-two patients with newly diagnosed HNSCC and 15 control patients were studied. PB T-lymphocyte activation was assessed by measuring by flow cytometry the percentage of PB T lymphocytes (CD3 + ) showing the early activation-related cell surface epitopes CD69+ or CD71+ (transferrin receptor) or the late activation epitopes CD25+ (IL-2 receptor) or HLA-DR+. RESULTS There was no significant difference in expression of T-lymphocyte activation markers between HNSCC patients and control patients, or any difference dependent on TNMG stage. In HNSCC patients a high percentage of CD71+ T lymphocytes predicted worse prognosis with a relative risk (RR) of 2.38 (confidence interval (CI): 1.04-5.47). A high mean value of the early (CD69 + /CD71 + ) (RR 2.37; CI: 1.06-5.29) or late (CD25 + /HLA-DR + ) (RR 3.31; CI: 1.39-7.88) activation markers also predicted worse prognosis. Following adjustment for TNM stage, high mean value of the early activation epitopes CD71+ (RR 2.89; CI: 1.22-6.85), the mean value of CD69 + /CD71+ (RR 2.58; CI: 1.12-5.91) and CD25 + /HLA-DR+ (RR 2.75; CI: 1.14-6.62) predicted worse prognosis.

Abstract
OBJECTIVES/HYPOTHESIS To assess the diagnostic feasibility and patient acceptance of a new developed diagnostic test for exercise induced upper airway flow limitation. STUDY DESIGN Clinical case control study including evaluation of contemporary ergo-spirometry and laryngoscopy continuously performed during exercise. METHODS Twelve nonsymptomatic controls and four young females with documented dyspnea and noisy breathing during exercise were studied. All subjects exercised to exhaustion on a treadmill while attached to a fully equipped ergo-spirometry unit and a fiberoptic laryngoscope linked to a video camera and a sound recorder. RESULTS The test situation was well tolerated. Two control subjects had a minor inspiratory synchronous medial motion of the aryepiglottic folds without limitation of laryngeal airflow. In the four symptomatic subjects, exercise induced inspiratory synchronous medial motion of the dorsal part of the aryepiglottic folds as well as vocal cord adduction and inspiratory stridor was demonstrated. CONCLUSION The continuous laryngoscopy exercise test was easy to perform, well tolerated, and can be implemented in future diagnostic work-up programs of laryngeal dysfunction.

Abstract
BACKGROUND Percutaneous dilatation tracheostomy (PDT) is increasingly being used in the intensive care unit (ICU), and has probably increased the number of procedures performed. The primary aim of this study was to document the short- and long-term outcome of patients with a tracheostomy performed during an ICU stay. METHODS Patients in our ICU who underwent an unplanned tracheostomy between 1997 and 2003 were included in this analysis. The type of tracheostomy (PDT or surgical tracheostomy) and time of the procedure were registered prospectively in our ICU database. Survival was followed using the People's Registry of Norway and morbidity data from the individual hospital record. These patients were also compared with a group of ICU patients ventilated for more than 24 h, but managed without a tracheostomy. We also compared patients who had early tracheostomy (less than median time to procedure) with those who had late tracheostomy. RESULTS Of the 2844 admissions (2581 patients), unplanned tracheostomy was performed during 461 admissions (16.2%) on 454 patients (17.6%). The median time to tracheostomy was 6 days. The ICU, hospital and 1-year mortality rates were 10.8, 27.1 and 37.2%, respectively, significantly less than those of the group ventilated without tracheostomy. The median time to decannulation was 14 days. Patients who had early tracheostomy had a more favourable long-term survival than those who had late tracheostomy. No procedure-related mortality was registered. CONCLUSIONS In our ICU, having a tracheostomy performed was associated with a favourable long-term outcome with regard to survival, and early tracheostomy improved survival in addition to consuming less ICU resources.

Abstract
Biopsies from carcinoma tissue and benign control mucosa from head and neck squamous cell carcinoma (HNSCC) patients were used to establish fragment (F)-spheroids in vitro. We have previously shown that autologous monocytes co-cultured with F-spheroids in vitro augment their secretion of monocyte chemotactic protein-1 (MCP-1). Presently, the aims of the present work were to study whether the metabolic activity, secreted products and/or specific receptor/ligand on the surface of the F-spheroids and monocytes are necessary for stimulation of the monocyte MCP-1 secretion upon F-spheroid co-culture. Actinomycin D (1 mug/ml for 24 h) pre-treatment of the F-spheroids abolished the monocyte MCP-1 co-culture response. Co-culture of monocytes and F-spheroids separated by a semi-permeable membrane showed a decreased, but still present, monocyte MCP-1 co-culture response. Conditioned medium from F-spheroids stimulated allogenous monocytes to secrete MCP-1. The addition of glucose or galactose, but not mannose, to co-cultures partially inhibited the monocyte MCP-1 co-culture response. The addition of anti-CD14 antibody diminished the MCP-1 co-culture response. In conclusion, the monocyte MCP-1 co-culture response is dependent on metabolically active spheroids, secreted stimuli, and is augmented by direct contact with F-spheroids, possibly via lectin-like receptors and the CD14 receptor.

Abstract
Monocyte fragment (F)-spheroid-stimulated and F-spheroid IL-6 and monocyte chemotactic protein (MCP)-1 secretion are related to inflammatory state, macrophage density and the TNM stage of patients with head and neck squamous cell carcinoma (HNSCC). Fragment (F)-spheroids from HNSCC patients in vitro secrete and stimulate autologous monocytes to secrete IL-6 and MCP-1. The aim of this investigation was to study this cytokine secretion in relation to other cytokines, spheroid composition and host factors.In series I (n=14) the densities of epithelial cells, fibroblasts and macrophages were determined in sections from F-spheroids and donor tissue. In series II (n=17) the TNM stage, donor inflammatory state, macrophage density and the secretion of F-spheroid- and monocyte F-spheroid-stimulated IL-6, MCP-1 and tumor necrosis factor (TNF)-alpha were determined. Epithelial cells were partly replaced by interstitial tissue during spheroid formation. Malignant (M) F-spheroids secreted more MCP-1 than benign (B) F-spheroids. No F-spheroid secreted measurable amounts of TNF-alpha. Monocytes secreted more IL-6 when co-cultured with MF- compared to BF-spheroids. Monocyte IL-6 MF- and MCP-1 MB-spheroid-stimulated secretion correlated with macrophage density. In addition, there was an association between MF- and BF-spheroid-stimulated monocyte cytokine secretion, as well as between BF- and MF-spheroid-stimulated MCP-1 secretion. An inverse relation was also noted between the erythrocyte sedimentation rate at monocyte harvest and the monocyte MCP-1 F-spheroid responses.

Abstract
A four-year-old boy had fallen from a tree in nursery school and had minor symptoms immediately after the trauma. He was admitted to the local casualty clinic the same night, but no signs of local injury were detected. The next morning he was admitted to the department of oto-rhino-laryngology at the local hospital due to increasing local swelling and pain in the cheek. A computed tomography examination demonstrated an extensive preauricular soft tissue swelling and a long central hypodensity from the left ear to the oropharynx. The presence of a penetrating foreign body was suspected and the boy was admitted to our hospital. An examination in general anaesthesia revealed a small skin lesion medial to the tragus in the left external auditory meatus and a wooden stick was seen crossing the oropharynx. The eight and a half centimetre long wooden stick had penetrated from the cartilaginous part of the left external auditory meatus to the right palatal tonsil. It was removed through a pre-auricular incision. No complications were observed and the boy could leave the hospital after four days of observation with antibiotic therapy and tetanus prophylaxis.

Abstract
CONCLUSION At diagnosis, control patients had the lowest depression levels and anxiety scores, followed by those with limited HNSCC disease and these with extended HNSCC disease. Anxiety and depression levels at diagnosis predicted prognosis via an association with extent of disease. Sense of humor, but not anxiety or depression level, predicted lower QoL and depression levels at follow-up. OBJECTIVE To study the association between anxiety score, depression level at sense of humor at diagnosis in head and neck squamous cell carcinoma (HNSCC) patients versus TNM stage, prognosis and depression level/quality of life (QOL) 6 years following diagnosis. A control group of patients with benign HN disease was also included. MATERIAL AND METHODS Male patients with newly diagnosed HNSCC (n =78) or benign HN (n =61) disease completed the following questionnaires: the Beck Depression Inventory, the Spielberger Trait Anxiety Inventory (state) and the Svebak humor questionnaire. Patients with cachexia or those aged >80 years were excluded. In the HNSCC patients, TNM stage, prognosis and QOL/depression level (n =27) were determined following successful therapy. RESULTS HNSCC patients reported high anxiety scores and lower depression levels than control patients, although there was overlap between the groups. N stage was associated with high anxiety scores and depression levels, whereas T stage was only associated with depression levels. Both anxiety scores and depression levels at diagnosis predicted prognosis through an association with TNM stage. Sense of humor, but not depression levels or anxiety scores, at diagnosis predicted QoL and depression levels at follow-up.

Abstract
Expression profile of 588 known genes relating to tumour biology, was examined between oral squamous cell carcinomas (OSCCs) and matching normal oral mucosal tissues (NOMTs) obtained from Sudanese (n=11) and Norwegian (n=11) patients. cDNA probes were synthesised from total RNA and hybridised with the Atlas human cancer cDNA expression array membranes. RT-PCR and immunohistochemistry were applied to confirm the expression pattern of a subset of the 588 genes. Differences in expression of the genes examined were found between the OSCCs and the NOMTs on the Atlas membranes. Several of these genes were either up- or down-regulated 1.6-fold or higher in the OSCCs compared to the NOMTs in the cases from the two populations. We found that 181 (31%) and 195 (33%) genes were either up-regulated or down-regulated in the OSCCs from the Sudan and Norway, respectively. From the total number of genes (n=376) found expressed in the OSCCs investigated from the two countries, 53 genes (14%) showed common expression profile [35 (66%) were up-regulated and 18 (34%) were down-regulated] and 70 genes (19%) showed opposite regulation status. Results of the RT-PCR and immunohistochemistry confirmed the hybridisation data. These findings may provide an OSCCs-specific gene expression profile in patients from the two countries, suggesting that alterations of 123 genes are common in these OSCCs regardless of ethnic differences or other socio-cultural risk factors between the patients from the two countries. The findings might further suggest that specific genes are frequently involved in these OSCCs, which may provide novel clues as diagnostic, prognostic biomarkers and/or targets for therapy. The Atlas human cancer cDNA expression array technique can be useful to examine and describe the expression profile of known genes frequently involved in OSCCs from different populations.

Abstract
OBJECTIVE We aimed to study whether personality scores, as measured using the Eysenck Personality Inventory (EPI), are associated with the risk and prognosis of head and neck squamous cell carcinoma (HNSCC). MATERIAL AND METHODS A total of 78 male patients with newly diagnosed HNSCC and 61 male patients with benign HN disease completed the EPI, which assesses the following: neuroticism, extraversion and lie score. The TNM stage, prognosis, diagnostic delay, level of education and smoking and alcohol consumption histories of the patients were also recorded. Patients with cachexia and those aged > 80 years were excluded. RESULTS The cancer patients had higher neuroticism scores (10.7 +/- 0.5 vs 8.3 +/- 0.6; p < 0.01) than the control patients. This association was shown to be secondary to the fact that neuroticism is associated with increased alcohol consumption. The personality trait scores were not associated with the length of diagnostic delay. It was also suggested that a low lie score predicted disease-specific death in the HNSCC patients (p = 0.02). Total survival also seemed to be predictable (p < 0.05). CONCLUSION Neuroticism is probably associated with a risk of HNSCC as a result of increased alcohol consumption. If the prognostic results can be replicated, a potentially important association between this personality trait and the prognosis of HNSCC is suggested.

Abstract
This study was performed in order to determine how monocytes and macrophages in co-culture with autologous head and neck squamous cell carcinoma (HNSCC) tumor tissue regulate the secretion of monocyte chemotactic protein-1 (MCP-1). The levels of MCP-1 were measured when autologous monocytes or monocyte-derived macrophages (MDMs) were co-cultured in vitro with autologous fragment (F)-spheroids established from HNSCC tumors or benign mucosa serving as control. MCP-1 secretion from co-culture stimulated monocytes and MDMs was increased compared to spontaneous MCP-1 secretion. With prolonged co-culture, MDMs showed a steady-state MCP-1 secretion above background levels for up to 96 h, even with change of co-culture media every 24 h. Addition of an anti-MCP-1 antibody to the medium decreased co-culture-induced monocyte IL-6 secretion. Addition of lipopolysaccharide (LPS) (1 [microg/ml) reduced MCP-1 secretion compared to spontaneous secretion in monocyte cultures. F-spheroids also secrete MCP-1, but at insignificant levels compared to the MCP-1 secretion from monocytes and MDMs. MCP-1 secretion from monocytes/MDMs is regulated differently when co-culture stimulation is compared to LPS-stimulation. Monocytes and MDMs expressed MCP-1 mRNA at a high level in all tested conditions: stimulated in co-culture, not stimulated or stimulated with LPS, indicating post-transcriptional regulation of MCP-1 secretion. The secretion of MCP-1 from tumor-derived F-spheroids, and the maintenance of co-culture MCP-1 secretion from MDMs in vitro, suggests that tumor-associated macrophages are a source of MCP-1 in HNSCC tumors.

Abstract
The secretion of interleukin (IL)-1 beta, IL-6 and tumour necrosis factor (TNF)-alpha were compared when freshly isolated autologous monocytes or monocytederived macrophages (MDMs) were co-cultured in vitro with autologous fragment (F)-spheroids established from a series of head and neck squamous cell carcinoma (HNSCC) patients. F-spheroids were generated from the malignant tumour (M-spheroids) or from benign mucosa (B-spheroids) from which the tumour originated control. If monocytes maturated towards MDMs before co-culture, the IL-6 secretion declined dependent on the extent of the MDM maturation by both M- and B-spheroid stimulation. When MDMs maturated in continuous co-culture, a steady-state secretion of IL-6 continued for several days but diminished when the culture medium was changed every 24 h. No co-culture-induced IL-1 beta or TNF-alpha was determined. Both the cytokine secretion and the mRNA gene expression revealed a different monocyte/MDM activation when co-culture and lipopolysaccharide (LPS)-stimulation were compared. Addition of anti-CD14 (10 microg/ml) decreased monocyte LPS-stimulated, but increased monocyte co-culture stimulated IL-6 secretion. In conclusion, M- and B-spheroids similarly stimulated monocytes and to a lesser extent MDMs. MDMs that maturated with F-spheroids present, retained responsiveness at the monocyte level. Co-culture-induced monocyte stimulation, as measured by IL-6 secretion, was not dependent on activation via the CD14 molecule.

Abstract
OBJECTIVES/HYPOTHESIS To determine if the T-lymphocyte and monocyte functions of peripheral blood mononuclear cells (PBMCs) from patients with head and neck squamous cell carcinomas (HNSCC) are predictive factors for outcome. STUDY DESIGN A prospective study describing the outcome, as to total survival and death by disease after at least 40 months observation, of 81 previously untreated male HNSCC patients in relation to PBMC T-lymphocyte and monocyte function. METHODS T-lymphocyte mitogenesis and the cytokine level in culture supernatants of PBMC as well as monocytes were analyzed. These parameters were related to survival by Cox regression and Kaplan-Meier survival analysis. RESULTS When patients with high versus low T-lymphocyte mitogen-stimulated proliferations were compared, a decreased proliferation was seen to be related to worse outcome. The predictive value of T-lymphocyte proliferation was shown to be an independent prognostic factor when adjusted for stage and stratified for anatomic location in survival analysis. The predictive value was also retained when the serum values of the major serum proteins and hormones and scores based on the smoking and alcohol history were added to the survival analysis with lymphocyte proliferation. Supernatant levels of gamma-interferon, interleukin (IL)-2, or IL-4 in PBMC cultures were not related to outcome. Monocyte function measured by endotoxin-stimulated IL-1beta, IL-6, IL-12, and tumor necrosis factor-alpha secretion did not relate to outcome of the patients. CONCLUSION The PBMC T-lymphocyte-stimulated proliferation is an independent prognostic factor for male HNSCC patients.

Abstract
Seventy newly diagnosed Caucasian male patients with head and neck squamous cell carcinomas (HNSCC) were included in the study. All patients were less than 80 years of age, with no cachexia or auto-immune disease, and they were not taking immuno-active medications. Monocytes from these patients were cultured in vitro and supplemented with autologous serum under ex vivo conditions or cultured with serum-free medium. Comparison was made to monocytes from 59 patients with benign HN diseases. Similar physical activity levels prior to testing as well as a minimum stress load were ensured in both groups. Increased monocyte supernatant levels were determined under ex vivo conditions of interleukin-1 beta (IL-1 beta), interleukin-6 (IL-6) and tumor necrosis factor (TNF)-alpha, but not of interleukin-12 (IL-12) with endotoxin stimulated monocytes of HNSCC patients compared to control conditions. Increased monokine levels were not present with mononuclear cell cultures stimulated with a T-cell general stimulatory agent or with purified monocytes not specifically stimulated. With endotoxin-stimulated monocytes under in vitro conditions, an increased supernatant was shown for TNF-alpha, but not IL-6. With serum from the different patients cultured with monocytes employed from a healthy control, no difference between the groups was shown in the IL-6 and TNF-alpha response to endotoxin stimulation. The differences in IL-1 beta and TNF-alpha, but not IL-6 levels were differentiated statistically from the smoking and alcohol histories of the patients. These findings suggest that the function of monocytes in general, and thus possibly all mononuclear phagocyte system cells in HNSCC patients, are altered.

Abstract
We have previously shown an increased T lymphocyte and monocyte responsiveness in peripheral blood mononuclear cells (PBMC) from patients with head and neck squamous cell carcinoma (HNSCC) compared with PBMC from control patients. This study reports T lymphocyte function of PBMC of 81 patients with HNSCC dependent on disease stage and prognosis. Males with HNSCC under 80 years of age without cachexia, with no auto-immune disease or previous cancer and on no immuno-active medication were included at the time of diagnosis of disease. The follow-up was for at least 18 months. When cells from patients with early vs late stage disease according to the T, N or T + N stage of HNSCC were compared, decreased in vitro mitogen-stimulated and spontaneous T cell proliferation was seen with increasing tumour stage. When patients were studied according to disease-specific survival, a decreased T lymphocyte mitogen-stimulated proliferation was observed to be associated with a poorer prognosis. No changes in prognosis were noticed related to decreased gamma-IFN, IL-2 or IL-4 level of the supernatants of the T lymphocyte-stimulated PBMC in vitro cultures. With stratification for disease stage, we determined that PBMC in vitro T lymphocyte-stimulated proliferation predicted outcome for the HNSCC patients. The results were similar for both laryngeal and oral cavity/pharyngeal cancers. The present investigation provides evidence to support the idea that the relationship between HNSCC and the immune system of the host may provide clinically useful information about prognosis.

Abstract
The in vitro responsiveness of peripheral blood mononuclear cells (PBMC) T lymphocytes was studied in 81 patients with limited or extended head and neck squamous cell carcinoma (HNSCC), as judged by T, N and T + N stages. Patients included in the study were males below 80 years of age, without auto-immune disease or cachexia, who were not taking any immuno-active medication at the time of diagnosis. The patients were divided into groups according to TNM stage T0-2 vs T3-4, N0-1 vs N2-3 or T + N0-3 vs T + N4-7. When cells from patients with early and late stage, according to T, N or T + N stage, were compared, we found a decreased level of mitogen stimulated T-cells and decreased spontaneous proliferation with increasing disease stage. The same was true if the in vitro mitogenesis of T-cells was analysed separately, depending on the laryngeal or oral cavity/pharyngeal origin of the patients' tumours. If the patients were divided into two groups based on N stage, decreased gamma-interferon, and to some extent interleukin (IL-2), but not IL-4 levels, were found to be related to the disease stage.

Abstract
T-lymphocyte cell function was studied in vitro in peripheral blood mononuclear cells (PBMC) from 61 male patients with head and neck squamous cell carcinomas compared to 46 control patients. Patients older than 80 years or with reduced tumor-related performance status as measured by Karnofsky score less than 75 were excluded. In contrast to previous similar studies, control subjects ensured a minimum stress load by sampling all patients on the day of either diagnostic or therapeutic surgery. PBMC were separated by density-gradient centrifugation and subsequently cultured with autologous sera in vitro. The mitogen concanavalin A (Con A), which stimulates all T-cell clones, was employed. Findings showed that increased Con A stimulation and PBMC proliferation occurred with PBMC from cancer patients compared to that from control patients. In contrast, no differences could be detected with respect to the stimulated supernatant level of interleukin-2, interleukin-4 or interferon-gamma between the groups. These results suggest that T-lymphocytes from PBMC are generally affected by neoplastic disease through either a supporting cell or serum factor.
