Syndromic craniosynostosis (SCS) is known to be associated with sleep-disordered breathing (SDB) in childhood. Problems can occur at various levels, but midface hypoplasia is a major factor in affected infants. Adenotonsillectomy (AT) has been proven to be efficacious as a first-line treatment of SDB in healthy children. However, its role in the treatment of this issue in those with SCS has not been evaluated. Owing to the multiple possible levels of obstruction in such individuals, AT may have no benefit. This study therefore aimed to evaluate the effectiveness of AT in this group of patients. Twenty-six children with SCS with moderate to severe obstructive sleep apnea (OSA) were treated with AT. The mean age at surgery was 4.5 years (range, 1.6-13.9 y). Seven had severe OSA, 11 had moderate OSA, and 7 had mild OSA preoperatively. Of 25 children, 15 (60%) demonstrated an improvement in sleep severity scores postoperatively. Overall, there was a significant improvement in the mean number of saturation dips greater than 4%/h and in the mean nadir of dips in saturation after the operation. There was no significant difference in mean oxygen saturation, number of pulse rate rises per hour, or percentage time spent less than 90% SaO2. Clinically, there is thought to be some benefit in performing AT in these groups of patients. In children with SCS, in whom the cause of obstruction might be at multiple levels, AT should still to be considered as first-line treatment in the management of OSA/SDB. We acknowledge that some children may still go on to require further airway intervention. Further multicenter trials would be useful to examine more closely the significance of the effects of AT in children with craniofacial disorders experiencing SDB.

OBJECTIVES Voice problems affect up to 30% of the population at some time during their life, and in particular it affects those who use their voice professionally. Patients who commonly present with dysphonia are often found to have symptoms of both allergy and reflux. Clinical examination of the larynx often makes it difficult to differentiate between the main causative factors of dysphonia, as the clinical findings on nasendoscopy between reflux and allergy are similar. Laryngopharyngeal reflux (LPR), an entity of gastro-oesophageal reflux, is a common diagnosis made in the voice out-patient clinic. Few studies have been able to successfully correlate management of LPR and outcome of dysphonia. Allergy or more specifically allergic rhinitis is said to affect approximately 24% of the population, but few studies have investigated its role in dysphonia. DESIGN Prospective observational study. SETTINGS University teaching hospital otolaryngology department. PARTICIPANTS Fifteen new patients with primary voice disorder were investigated for possible LPR and allergy from April 2007 to October 2007. All patients were tested using the validated reflux symptom index (RSI), reflux finding score (RFS) to diagnose LPR, and both skin prick tests (SPT) and nasal nitric oxide (NO) levels to diagnose the presence of allergy. MAIN OUTCOME MEASURES Prevalence of symptoms of reflux and allergy in patients presenting with primary voice disorders, and also whether dysphonia thought to be caused by LPR could actually be due to allergy. RESULTS No positive correlation or statistical significance was found between reflux and allergy. From our sample 20% (three patients) were diagnosed with LPR and 67% (ten patients) with allergy. The three patients diagnosed with LPR also had concomitant allergy. CONCLUSIONS In our patient cohort, three times as many patients demonstrated allergy compared with LPR. This has led us to question if some patients with allergic laryngitis are being misdiagnosed with LPR and thereby being over-treated with proton pump inhibitors (PPIs).

Abstract Objectives. To investigate the relationship between air-borne allergen exposure and Voice Handicap Index scores in patients seeking medical treatment for rhinitis. Methods. As we had previously identified a higher-than-expected incidence of allergy in patients presenting to a voice clinic, we undertook a prospective audit of patients without specific voice-related complaints presenting to a rhinology clinic to see if these patients might have unrecognized vocal dysfunction. To this end 70 consecutive patients with no pre-reported voice-related symptoms presenting to a teaching hospital rhinology clinic underwent skin prick testing to common air-borne allergens and completed the Voice Handicap Index (VHI) questionnaire. Discriminant performances in the Voice Handicap Index and its individual domains and questions were determined using analysis of variance. An allergy-specific subset of the VHI was constructed and tested using receiver operating characteristic (ROC) statistics. Results. There were 30 males and 40 females. Mean age was 36 ± 12 years. Dust mite (83%), house dust mite (55%), and grass pollen (40%) were the commonest allergens, and 23 patients did not react to common allergens. Mean VHI score was 23.7 ± 20.1 in patients with ≥4 allergens, 10.8 ± 21.3 in patients with fewer than 4 allergies, and 7.8 ± 8.5 in non-allergics (P = 0.044; analysis of variance). Nine VHI questions best discriminated between allergic and non-allergic patients (P < 0.05), and the combined VHI-9 score had a ROC area under the curve of 0.85. Conclusions. Patients with more air-borne allergies have a higher incidence of undiagnosed vocal dysfunction, as determined by the raised Voice Handicap Index score, than those with fewer or no such allergies. As noted, earlier work has shown that, conversely, patients with vocal dysfunction have a high incidence of undiagnosed allergy.

Obstructive sleep apnea in children with syndromic craniosynostosis is a well-documented entity, and airway management in these group of children is difficult, with well-documented cardiorespiratory and neurodevelopment consequences. Numerous well-documented techniques are available for airway management in this group of children. In our center, the nasopharyngeal airway (NPA) is the first-line treatment. This study aimed to evaluate the improvement in health-related quality of life in this group of children using the Glasgow Childrens Benefit Inventory.We conducted a retrospective postal study of 24 patients with craniofacial disorders who had an NPA inserted as part of their airway management. A 79.2% (n = 19) response rate was obtained. Mean (SD) age was 5.8 (4.1) years. Patients were classified into 3 main groups: Crouzon (n = 11), Apert (n = 6), and Pfeiffer (n = 2) syndromes.There was improvement in 3 of the 4 domains, namely, learning (P = 0.006), vitality (P = 0.003), physical (range, −3 to 8; mean, 2; P = 0.005). There was significant improvement in the sleep study parameters; however, no correlation was found between this and the Glasgow Childrens Benefit Inventory findings. Parents also preferred an NPA as opposed to a tracheostomy when given a choice.Our study shows that NPA confers significant improvement not only in health-related quality of life but also in severity of obstructive sleep apnea as judged by sleep study parameters. The NPA is also well tolerated by patients and is much preferred by parents for airway management for their children as opposed to having a tracheostomy. We think that this should be considered in other centers as first-line management in children with syndromic craniosynostosis.

BACKGROUND According to the Federal Institution of Health Insurance, ENT doctors perform more skin prick tests for the diagnosis of allergic rhinitis (AR) than other medical specialties in Belgium. However, immunotherapy (IT) is not practiced by all. This study aims to obtain insight into IT practice by ENT doctors, the type of IT performed and the reasons not to perform IT. METHODOLOGY A questionnaire was sent to all registered ENT doctors of Belgium (n=648), involving questions on type and duration of ENT practice, geography and gender. In addition, the questionnaire informed about diagnosis of AR, indication for IT, type of IT performed, and reasons not to perform IT and referral pattern. RESULTS The response rate among ENT doctors was 54%, with 7% of responders being excluded as they do not diagnose AR. 81% of Belgian ENT doctors make the indication for IT in AR patients, with 19% neglecting the indication for IT in AR patients. The two main reasons for not indicating IT are lack of expertise and the perception of high costs associated with IT. 70% of ENT specialists are practicing IT themselves, with sublingual IT being mostly performed. Interestingly, IT is mostly frequently performed by those ENT doctors with long-standing ENT practice, in private practice and in Wallonia. CONCLUSION Despite the high prevalence of AR in ENT practice, IT is most frequently performed by ENT doctors with longstanding practice, working in private practice and/or in the French speaking part of Belgium. Among the different types of IT, sublingual IT is the most frequently performed means of IT by ENT doctors.OBJECTIVE To investigate the role of inflammation in non-allergic rhinitis (NAR) patients in a large series to establish the prevalence of different NAR-subtypes, clinical features and the role of nasal cytology in the diagnostic algorithm. METHODOLOGY Patients were selected out of 3650 individuals who spontaneously presented at our institution. We consecutively enrolled 519 NAR-patients in an analytical cross-sectional study between November 2007 and June 2013 (level of evidence: 3b). All patients underwent rhinological evaluation including symptoms questionnaire, endoscopy, CT scan, allergy tests and nasal cytology. RESULTS The inflammatory cell infiltrate affects the severity of symptoms differently, allowing for identification of different phenotypes of NAR. We distinguished two groups: “NAR without inflammation”(NAR-) and “NAR with inflammation”(NAR+), in addition to different NAR-subtypes with inflammation. A significant difference was observed in terms of clinical symptoms and association with comorbidities (previously diagnosed asthma and aspirin intolerance) between NAR–, NAR+ and between different NAR+ subtypes. CONCLUSION Our data suggest that NAR- and NAR with neutrophils behave similarly, showing lower symptom score values and a lower risk of association with comorbidities compared to NAR with eosinophils and mast cells (singularly or mixed). In our belief it is very important to establish the presence and type of inflammation in non-allergic rhinitis patients and nasal cytology is a very useful test in correct differential diagnosis.OBJECTIVE To assess the applicability of the Peak Nasal Inspiratory Flow (PNIF) curves in follow-up of children in the treatment of allergic rhinitis. METHODS Prospective study of 40 patients with AR, grouped in corticosteroid spray versus physiological saline solution use. Follow up for 10 weeks through clinical score and PNIF percentages in relation to the reference curves, with was-out at week 8. Statistical assessment of the effect of treatment on variation of PNIF and clinical score was calculated by ANOVA model and Multiple Comparison of Means Test - Least Significant Difference. RESULTS There was a statistically significant influence of the group, time and interaction between time and group on PNIF percentages. Throughout follow up, patients from the treatment group had mean PNIF percentages significantly higher than the placebo group. Clinical score results also demonstrated a statistically significant influence between the groups, time and interaction between time and group. CONCLUSION Increase in PNIF percentage values observed in children treated with intranasal corticosteroids revealed the applicability of PNIF curves in their follow up.OBJECTIVE This study aims to examine humans ́ abilities to localize odorants within the open field. METHODOLOGY Young participants were tested on a localization task using a relatively selective olfactory stimulus (2-phenylethyl-alcohol, PEA) and cineol, an odorant with a strong trigeminal component. Participants were blindfolded and had to localize an odorant source at 2 m distance (far-field condition) and a 0.4 m distance (near-field condition) with either two nostrils open or only one open nostril. RESULTS For the odorant with trigeminal properties, the number of correct trials did not differ when one or both nostrils were used, while more PEA localization trials were correctly completed with both rather than one nostril. In the near-field condition, correct localization was possible in 72-80% of the trials, irrespective of the odorant and the number of nostrils used. Localization accuracy, measured as spatial deviation from the olfactory source, was significantly higher in the near-field compared to the far-field condition, but independent of the odorant being localized. CONCLUSION Odorant localization within the open field is difficult, but possible. In contrast to the general view, humans seem to be able to exploit the two-nostril advantage with increasing task difficulty.BACKGROUND This study was designed to assess if illness perception, mood state and coping strategies differ according to allergic rhinitis (AR) persistence and severity. METHODS Illness perception, mood profiles, coping behaviors and rhinitis symptoms were assessed by means of validated tools inpatients classified according to the Allergic Rhinitis and Its Impact on Asthma (ARIA) guidelines. RESULTS Two hundred and thirty-one patients underwent data analysis. No difference in age, sex, socio-economic status, smoking habits was detected comparing patients according to AR severity, duration or 4 ARIA classes. Patients with intermittent AR reported higher scores than those with persistent AR in confusion-bewilderment of Profile of Mood States (POMS); patients with moderate/severe rhinitis had significantly higher scores than those with mild rhinitis in TSSS, Identity and Consequences. No differences were detected in all assessed outcomes in the 4 ARIA classes. CONCLUSIONS The patients perspective about AR is independent of persistence and severity of symptoms. This may explain why AR remains under-diagnosed and under-treated, even in its most severe forms. Self-management plans should consider the patients perspective.The assessment of Chronic Rhinosinusitis, like any other disease, may involve multiple possible disease manifestations, including subjective patient-reported outcomes, objective disease (e.g. endoscopy or radiographic), and physician-driven (e.g. need for systemic medications). Disease control is often used as a global metric of disease burden and represents the extent to which disease manifestations are within an acceptable range. Achieving control is an important treatment goal.The European Position Paper on Rhinosinusitis and Nasal Polyps 2020 is the update of similar evidence based position papers published in 2005 and 2007 and 2012(1-3). The core objective of the EPOS2020 guideline is to provide revised, up-to-date and clear evidence-based recommendations and integrated care pathways in ARS and CRS. EPOS2020 provides an update on the literature published and studies undertaken in the eight years since the EPOS2012 position paper was published and addresses areas not extensively covered in EPOS2012 such as paediatric CRS and sinus surgery. EPOS2020 also involves new stakeholders, including pharmacists and patients, and addresses new target users who have become more involved in the management and treatment of rhinosinusitis since the publication of the last EPOS document, including pharmacists, nurses, specialised care givers and indeed patients themselves, who employ increasing self-management of their condition using over the counter treatments. The document provides suggestions for future research in this area and offers updated guidance for definitions and outcome measurements in research in different settings.BACKGROUND Endoscopic dacryocystorhinostomy (EN-DCR) is a commonly used procedure in the treatment of nasolacrimal duct obstruction (NLDO). However, there is no generally accepted disease-specific questionnaire for assessing outcomes. METHODOLOGY We conducted a prospective study to initially validate a Nasolacrimal Duct Obstruction Symptom Score questionnaire(NLDO-SS) and to evaluate the long-term success of EN-DCR procedures. Seventy-six patients (86 eyes) were evaluated in follow-up visits at 1-8 years after EN-DCR. The patients completed the NLDO-SS questionnaire twice, first, at home and, second,after receiving information from the otorhinolaryngologist, during the visit. The surgical outcome was considered successful if the irrigation succeeded and if the patient symptoms were relieved as assessed with the NLDO-SS. RESULTS The diagnostic accuracy of the NLDO-SS was 84%, sensitivity 82%, specificity 85%, positive predictive value 58%, negative predictive value 95%, odds ratio 26, risk ratio 11 and usefulness index 0.55. Cronbachs alpha was 0.85, and the test-retest reliability coefficient was 0.87. The long-term success rate after EN-DCR was 79%. CONCLUSION The NLDO-SS iss a feasible clinical tool in assessing the success of EN-DCR. The success rate was found to decrease EN-DCR at long-term follow-up.
