Real-Life Experience of Biologic Treatment for Asthma on Chronic Rhinosinusitis: A Finnish Cohort.

INTRODUCTION: Biologics are used in the treatment of severe asthma and chronic rhinosinusitis with nasal polyps (CRSwNP). The purpose of this retrospective study was to evaluate the effects of biologics initiated for asthma on coexistent CRS and the influence of comorbid factors, including aspirin-exacerbated respiratory disease (AERD) and secretory otitis media (SOM). METHODS: A review of electronic health records (2009-2020) at a Finnish tertiary center was conducted to identify CRS patients treated with biologics for their asthma. We identified the type of biologic and treatment response, by comparing nasal polyp score (NPS), sinonasal outcome test (SNOT)-22, need for oral corticosteroids (OCS) and antibiotics, frequency of visits, and endoscopic sinus surgeries (ESS) pretreatment and during treatment. RESULTS: 55 patients were treated with anti-immunoglobulin E (IgE) (n = 18) or anti-interleukin-5/5-receptor (IL-5/5R) (n = 37) biologics. Treatment lasted for an average of 4.1 years. Seventy-five percent (n = 41) had CRSwNP and 25% (n = 14) had CRSsNP. Of all patients, 24% (n = 13) had comorbid AERD and 22% (n = 12) had SOM. Biologic therapy reduced the need for OCS courses (anti-IgE, n = 17, p = 0.03; anti-IL-5/5R, n = 35, p = 0.01) and for daily OCS in anti-IL-5/5R (n = 35, p = 0.001) but not in anti-IgE patients (n = 16, p = 0.07). Biologics also improved NPS by 0.5 point (n = 32, p = 0.009) and SNOT-22 by 14 points (n = 7, p = 0.02) in CRSwNP patients. The overall discontinuation rate was 37.7% (n = 20) and was independent of type of biologic. CONCLUSION: Treatment with anti-IgE and/or anti-IL-5/5R biologics reduced the overall need for OCS medication in individuals with asthma and concomitant CRS, but despite this, the discontinuation rate was high.

Translation, cross-cultural adaptation, and validation of the sino-nasal outcome test (snot)-22 for Finnish patients.

PURPOSE: The Sino-Nasal Outcome Test-22 (SNOT-22) is the most commonly used disease-specific quality of life questionnaire in rhinology. The purpose of this prospective study was to translate and validate SNOT-22 into Finnish. METHODS: The validation process followed the guidelines proposed for cross-cultural adaptation of health-related measures of quality of life. The study consisted of three groups: rhinologic out-patients (N = 96), FESS patients (N = 49) and healthy controls (N = 79). Out-patient and FESS groups completed the questionnaire twice (answers A and B), out-patients after two weeks and FESS patients after 3 months. Validity, reliability and responsiveness were evaluated. RESULTS: The mean SNOT-22 sum score of the out-patient questionnaires were 35.3 points (answer A) and 32.4 points (answer B). ICC in out-patient group was 0.879. For the FESS patients, the mean pre- and postoperative (answer A and B) SNOT-22 sum scores were 46.8 and 21.9 points, respectively (p < 0.0001). The mean SNOT-22 of healthy controls was 8.9 points. The out-patients (answer A) and healthy controls had statistically significant difference in SNOT-22 scores (p < 0.0001). CONCLUSIONS: The results of our study show that the validated Finnish version of the SNOT-22 questionnaire demonstrates good validity, reliability and responsiveness.

Do aggravating rhinologic symptoms at work indicate occupational exposure? A cross-sectional outpatient clinic study.

BACKGROUND: Air impurities can exacerbate or cause rhinologic diseases. However, only a few studies have assessed rhinologic patients' symptoms at work. OBJECTIVE: This study surveys the impact of work on rhinology clinic patients' quality of life in relation to work-related respiratory exposures. In addition, we surveyed patients' sick leave periods. METHODS: We recruited adult employed rhinology patients referred to the otorhinolaryngology clinic. A total of 177 patients were included. We collected data on patients' medical history, rhinologic disease-specific and generic quality of life, current or most recent job title, a description of current work, nasal symptoms, possible worked-related symptom triggers and sick leave periods during the preceding year. RESULTS: In total, 101 (57.1%) patients reported exacerbated rhinologic symptoms at work and reported more severe rhinologic disease and a lower disease-specific quality of life compared to non-work-related rhinologic patients (P = 0.008). A minority, 24.3% of our patients were exposed to any specific occupational respiratory sensitizer or irritant at work. The mean sick leave period due to rhinologic disease was 7.7 days per year. CONCLUSIONS: Exposure to specific occupational sensitizers or irritants did not associate with increasing symptoms at work or quality of life amongst our patients. Most rhinology patients reported exacerbated symptoms at work. They appeared to be more symptomatic than the rest of the patients and, therefore, possibly hyperreactive to unspecific respiratory triggers at work. Rhinologic diseases caused our patients a marked burden with high work absenteeism.

Eosinophilia, asthma, NERD and the use of oral corticosteroids predict uncontrolled chronic rhinosinusitis with nasal polyps after surgery.

BACKGROUND: Severe uncontrolled chronic rhinosinusitis with nasal polyps (CRSwNP) is a challenging condition to treat. The European Position Paper on Rhinosinusitis and Nasal Polyps 2020 (EPOS2020) has the following criteria when considering biological therapy for severe uncontrolled CRSwNP: eosinophilia, need for oral corticosteroids (OCS), symptom score, loss of sense of smell and co-morbid asthma. OBJECTIVE: This study aimed at finding associations of baseline factors with uncontrolled CRSwNP after endoscopic sinus surgery (ESS). METHODS: Electronic health record data of CRSwNP patients (N = 137) undergoing ESS in 2002-17 were used. Endpoints of uncontrolled CRSwNP were revision ESS, purchased OCS and antibiotic courses during follow up. Baseline factors were chosen based on EPOS2020 and the data available: nasal polyp (NP) eosinophilia, peripheral blood eosinophilia, co-existing asthma and/or non-steroidal anti-inflammatory drug exacerbated respiratory disease (NERD), need for OCS during the previous year, previous ESS, endoscopic NP score, and Lund-Mackay score of sinus computed tomography scans. RESULTS: During the follow-up of 10.1 ± 3.1 (mean ± standard deviation) years, 35 (25.5%) individuals underwent revision ESS. The best predictive model was obtained by a sum of baseline (1) blood eosinophilia ≥ 250 cells/≥l and/or NP eosinophilia ≥ 30% (Eos), (2) asthma/NERD, and (3) ≥ 1 OCS/year. It was significantly associated with revision ESS, purchased doctor-prescribed OCS and antibiotic courses during follow-up. CONCLUSIONS: We identified similar predictive variables for uncontrolled CRSwNP that are used in the EPOS2020 indications of biological therapy, thus suggesting that these estimates are usable in clinical practice.

Different rhinologic diseases cause a similar multidimensional decrease in generic health-related quality of life.

BACKGROUND: Previous studies illustrated that chronic rhinosinusitis and allergic rhinitis represent individual and socioeconomic burdens to a patient. However, few studies exist on the health-related quality of life (HRQoL) amongst other rhinologic patients. Our study investigated the generic HRQoL in different rhinologic diseases. METHODOLOGY: Unselected adult rhinologic patients requiring special care at the Helsinki University Hospital were enrolled in this cross-sectional, questionnaire-based prospective study in February, May, August and November 2014. Patients were mailed a medical history questionnaire and a generic 15-dimension (15D) HRQoL questionnaire. Diagnostic data were collected from electronic patient records following outpatient visits. Patient HRQoL scores were compared to an age- and sex-standardised general population sample obtained from a large national health examination survey. RESULTS: This study consisted of 337 rhinologic patients (mean age 50.2 years, 50.4% men). The mean 15D score amongst rhinologic patients (0.865) was both statistically significant and clinically poorer than that amongst the general population (0.929). Rhinologic patients fared poorly on most dimensions of the 15D instrument, particularly on sleep, discomfort and symptoms, breathing and vitality. Patients with obstructive sleep apnoea (OSA) were particularly affected. Yet, comparing the five most common rhinologic diagnostic groups revealed no significant differences in the mean 15D scores. CONCLUSIONS: Rhinologic diseases, independent of the underlying cause, substantially and negatively affect patients' HRQoL. OSA decreases HRQoL in these patients, although patients without an OSA diagnosis still suffer from a clinically important impairment of HRQoL and poor quality sleep.

CPAP interface: satisfaction and side effects.

PURPOSE: This study aimed to evaluate the care receiver's satisfaction with the continuous positive airway pressure (CPAP) interfaces. METHODS: A questionnaire with visual analog scales was sent to all our CPAP patients (0 = absolutely unsatisfied, 100 = very satisfied). From the ResMed ResScan program, we obtained the CPAP daily use and air leak values. RESULTS: We received 730 answers (70 % of participants); females comprised 22 %. A total of 391 patients had ResMed interfaces, 227 had Respironics, 87 had Fisher & Paykel (F&P), and 25 patients had other interfaces. Interfaces were nasal for 79 %, nasal pillows for 9 %, oronasal for 9 %, and unidentified for 3 % of cases. The mean ± SD satisfaction rate was 68 ± 25. No statistically significant differences were found regarding the type or brand of interface, previous interface experience, or the age or gender of the patient. Users of ResMed interfaces had significantly (p < 0.01) fewer cases of disturbing leaks than did users of Respironics or F&P interfaces (60 vs. 70 and 72 %, respectively). The ResMed Ultra Mirage interface had the fewest cases of disturbing leaks. Values for the measured median leaks were a mean of 5.9 ± 7.2 l/min, and those for the maximum leaks were 39.3 ± 22.2 l/min with no differences between brands. The users of F&P interfaces experienced significantly (p < 0.01) more comfort and used the CPAP device significantly (p < 0.007) more than did users of ResMed or Respironics interfaces (88 % of cases vs. 65 and 57 % and 6.2 ± 2.6 vs. 5.3 ± 2.8 or 5.8 ± 2.8 h/day, respectively). CONCLUSIONS: The majority of patients consider the use of the CPAP interface disturbing even though the satisfaction rate is good with no differences between brands.

Acute versus late endoscopic dacryocystorhinostomy in treatment of acute dacryocystitis: A prospective randomised trial with an 18-month follow-up.

PURPOSE: To compare the long-term symptom resolution and use of resources of performing endoscopic dacryocystorhinostomy (enDCR) in acute or delayed phase in patients with acute dacryocystitis (AD). METHODS: This prospective, randomised controlled trial was conducted in Helsinki University tertiary Eye and Ear, Nose and Throat (ENT) Hospitals between September 2013 and January 2019. Fifty patients aged 18 and above presenting with AD in the emergency care were randomised into acute and delayed enDCR surgery groups, performed in 1 week or 4 months from the diagnosis of AD. The follow-up time was 18 months. Outcome measures were subjective epiphora, lacrimal symptoms and visual analogue scale (VAS) pain scores, the number of hospitalised and unhealthy days, use of medication and openness in lacrimal syringing and dye test. RESULTS: EnDCR was performed on 24 patients in the acute and 19 in the delayed group. There were no significant differences between the groups in follow-up lacrimal symptoms, syringing test, dye test or use of resources. At the 18 months' follow-up, 21/23 (91.3%) in the acute group and 12/13 (92.3%) in the delayed group had no disturbing lacrimal symptoms. When reoperations and dropouts are considered, beneficial outcome was 22/24 (91.7%) in the acute and 12/16 (75%) (p = 0.195) in the delayed group. The acute group had significantly fewer pain medication days than the delayed group, 3 versus 10.5 (p = 0.03). CONCLUSION: Acute enDCR is associated with fewer pain medication days and equal resolution of lacrimal symptoms and use of resources.

Chronic Rhinosinusitis Outcome Registry (CHRINOSOR): Establishment of an International Outcome Registry Driven by mHealth Technology.

BACKGROUND: Real-world evidence (RWE) is a valuable instrument to better understand the patient journey and effectiveness of therapies. RWE on the prevalence of uncontrolled chronic rhinosinusitis (CRS) and CRS natural course of disease across Europe is scarce. In addition, there is limited RWE that enables comparison of the effectiveness of marketed therapies including topical or systemic corticosteroids, sinus surgery, or biologics. OBJECTIVE: To establish an international CHRonic rhINOSinusitis Outcome Registry (CHRINOSOR) based on real-world data collection enabled by mobile health technology. METHODOLOGY: A digital platform, Galenus Health, supporting patients and physicians in the management of chronic respiratory diseases, is used to collect data on patient profile, disease history, patient outcomes, and a set of relevant clinical outcomes. Adult patients with a diagnosis of CRS are eligible for inclusion. RESULTS: A collaborative scientific network of 17 university ear-nose-throat (ENT) clinics from 10 European countries has been established with the aim to collect real-world data in a longitudinal and standardized manner. The Galenus Health digital platform is currently being implemented in these ENT clinics taking into account legal, privacy, and data security aspects. Up to 300 patients have already been included. CONCLUSIONS: CHRINOSOR is a collaborative effort that aims at improving our understanding of CRS, its comorbidities, and the effectiveness of its treatments. Ultimately, these insights will guide us as scientific community to develop future care pathways informed by RWE.

[Nasal polyposis]. / Nenän polyypit.

Nasal polyposis is an adult type mucosal inflammation of unknown etiology. Polyps are found in 4% of the Finns and in 17% of asthma patients. The first-line treatment is corticosteroid nasal spray and, if necessary, corticosteroid nasal drops or orally administered corticosteroids. Lavages with sodium chloride solution can be utilized as supportive therapy. A combination of antibiotics and corticosteroida is worthwhile in purulent rhinosinusitis. Surgery is contemplated, if conservative therapy is ineffective. In ASA-intolerant asthmatics nasal polyposis may be severe and recur in spite of drug and surgical therapy.

Using machine learning for the personalised prediction of revision endoscopic sinus surgery.

BACKGROUND: Revision endoscopic sinus surgery (ESS) is often considered for chronic rhinosinusitis (CRS) if maximal conservative treatment and baseline ESS prove insufficient. Emerging research outlines the risk factors of revision ESS. However, accurately predicting revision ESS at the individual level remains uncertain. This study aims to examine the prediction accuracy of revision ESS and to identify the effects of risk factors at the individual level. METHODS: We collected demographic and clinical variables from the electronic health records of 767 surgical CRS patients ≥16 years of age. Revision ESS was performed on 111 (14.5%) patients. The prediction accuracy of revision ESS was examined by training and validating different machine learning models, while the effects of variables were analysed using the Shapley values and partial dependence plots. RESULTS: The logistic regression, gradient boosting and random forest classifiers performed similarly in predicting revision ESS. Area under the receiving operating characteristic curve (AUROC) values were 0.744, 0.741 and 0.730, respectively, using data collected from the baseline visit until six months after baseline ESS. The length of time during which data were collected improved the prediction performance. For data collection times of 0, 3, 6 and 12 months after baseline ESS, AUROC values for the logistic regression were 0.682, 0.715, 0.744 and 0.784, respectively. The number of visits before or after baseline ESS, the number of days from the baseline visit to the baseline ESS, patient age, CRS with nasal polyps (CRSwNP), asthma, non-steroidal anti-inflammatory drug exacerbated respiratory disease and immunodeficiency or suspicion of it all associated with revision ESS. Patient age and number of visits before baseline ESS carried non-linear effects for predictions. CONCLUSIONS: Intelligent data analysis identified important predictors of revision ESS at the individual level, such as the frequency of clinical visits, patient age, Type 2 high diseases and immunodeficiency or a suspicion of it.

The relative proportion of comorbidities among rhinitis and rhinosinusitis patients and their impact on visit burden.

Background: The aim was to evaluate the relative proportion of Non-steroidal anti-inflammatory drug exacerbated respiratory disease (NERD) and other comorbidities, and their impact on the burden of outpatient visits due to allergic rhinitis (AR), non-allergic rhinitis (NAR), acute rhinosinusitis (ARS), and chronic rhinosinusitis with nasal polyps (CRSwNP) and without (CRSsNP). Methods: We used hospital registry data of a random sample of 5080 rhinitis/rhinosinusitis patients diagnosed during 2005-2019. International Statistical Classification of Diseases and Related Health Problems (ICD10) diagnoses, visits, and other factors were collected from electronic health records by using information extraction and data processing methods. Cox's proportional hazards model was used for modeling the time to the next outpatient visit. Results: The mean (±standard deviation) age of the population was 33.6 (±20.7) years and 56.1% were female. The relative proportion of AR, NAR, ARS, CRSsNP and CRSwNP, were 33.5%, 27.5%, 27.2%, 20.7%, and 10.9%, respectively. The most common other comorbidities were asthma (44.4%), other chronic respiratory diseases (38.5%), musculoskeletal diseases (38.4%), and cardiovascular diseases (35.7%). Non-steroidal anti-inflammatory drug exacerbated respiratory disease existed in 3.9% of all patients, and 17.7% of the CRSwNP group. The relative proportion of subjects having 1, 2, 3 and ≥ 4 other diseases were 18.0%, 17.6%, 17.0%, 37.0%, respectively. All diseases except AR, ARS, and mouth breathing, were associated with a high frequency of outpatient visits. Conclusions: Our results revealed a high relative proportion of NERD and other comorbidities, which affect the burden of outpatient visits and hence confirm the socioeconomic impact of upper airway diseases.

Seasonal Variation in Generic and Disease-Specific Health-Related Quality of Life in Rhinologic Patients in Southern Finland.

BACKGROUND: Seasonal variation in exacerbations, hospitalisations, and mortality statistics has been reported for some diseases. To our knowledge, however, no published studies exist on the seasonality of health-related quality of life (HRQoL) amongst rhinologic patients. AIMS/OBJECTIVES: This study, therefore, aimed to investigate the possible seasonal variation in rhinologic patients' HRQoL using the rhinologic disease-specific Sino-Nasal Outcome Test-22 (SNOT-22) and the generic 15D HRQoL instrument. MATERIAL AND METHODS: We enrolled unselected adult rhinologic patients requiring specialist care at the Helsinki University Hospital in this cross-sectional, questionnaire-based prospective study during four seasons: February (winter), May (spring), August (summer), and November (autumn). Patients received SNOT-22 and 15D questionnaires via post. The Finnish Meteorological Institute supplied climate data from these months. RESULTS: SNOT-22 and 15D data were available for 301 and 298 patients, respectively. We found no statistically significant differences (p = 0.948) between the mean monthly 15D scores or mean SNOT-22 scales. Furthermore, the mean SNOT-22 subscales did not differ between the monthly study periods. CONCLUSIONS AND SIGNIFICANCE: Our study shows that seasonality did not impact rhinologic patients' SNOT-22 or 15D HRQoL scores. Thus, these questionnaires can be used for follow-up amongst rhinologic patients regardless of season.

Factors Affecting the Control of Chronic Rhinosinusitis With Nasal Polyps: A Comparison in Patients With or Without NERD.

OBJECTIVES: The aim was to compare the control of chronic rhinosinusitis with nasal polyps (CRSwNP) after endoscopic sinus surgery (ESS), in patients with/without nonsteroidal anti-inflammatory drug exacerbated respiratory disease (NERD).Study Desing: A retrospective hospital-based sample of CRSwNP patients with/without NERD with follow-up. SETTING: Tertiary rhinology centers. METHODS: Electronic patient record data from 116 CRSwNP patients (46 with NERD and 70 without NERD) undergoing ESS during 2001-17 were studied. Mean follow-up time was 9.9 years (range 1.1-15.3). Endpoints reflecting uncontrolled CRSwNP were revision ESS, and need for rescue/advanced therapy (e.g. antibiotics, oral corticosteroids and/or biological therapy) during follow-up. NERD was variable of interest and gender, age, asthma, allergic rhinitis (AR), smoking, Lund-Mackay (LM) score of sinus computed tomography scans previous ESS and baseline total ethmoidectomy were used as covariates. RESULTS: Twenty-one (49.7%) NERD patients and 18 (25.7%) non-NERD patients underwent revision ESS within a mean ± SD of 4.3 ± 2.8 and 3.7 ± 2.6 years, respectively (p = .013, by Logrank test). In Cox´s regression models, NERD, female gender, young age, asthma, AR, previous ESS, and lack of total ethmoidectomy were associated with revision-ESS. In adjusted model, only the total ethmoidectomy predicted revision-free survival. In adjusted logistic regression model, there was an insignificant trend that NERD and LM score were associated with the need for rescue/advanced therapy in the follow-up. CONCLUSIONS: Patients with NERD had higher risk of uncontrolled CRSwNP than patient group without NERD, as measured by revision ESS and/or need for rescue/advanced therapy in the follow-up. In addition, baseline total ethmoidectomy was associated with revision-free survival.

Frequency of upper airway symptoms before and during continuous positive airway pressure treatment in patients with obstructive sleep apnea syndrome.

BACKGROUND: Upper airway side effects are common during nasal continuous positive airway pressure (nCPAP) treatment and may affect the use of nCPAP. OBJECTIVES: It was our aim to evaluate the prevalence of upper airway symptoms in obstructive sleep apnea syndrome (OSAS) patients before and during nCPAP treatment and to assess the possible association between the symptoms and long-term adherence to the treatment. METHODS: We examined 385 consecutive OSAS patients (79% men, mean age ± SD 52 ± 10 years and apnea-hypopnea index 33 ± 23) by means of a prospective questionnaire-based survey. The patients filled in questionnaires about upper airway symptoms before starting nCPAP and after 2 months of treatment. RESULTS: Upper airway symptoms were common before starting nCPAP: 61% of the patients reported dryness of mouth, 54% dryness of throat, 52% nasal stuffiness, 51% dryness of nose, 30% sneezing, 24% mucus in throat, 17% rhinorrhea, and 6% nose bleeds daily or almost daily. In CPAP users there was a significant decline in the number of patients with frequent mouth (37%), throat (34%), nose (28%) dryness and nasal stuffiness (24%). There was no difference in upper airway symptoms before nCPAP treatment between those who continued the treatment after 1 year and those who terminated the treatment. CONCLUSIONS: The most common upper airway symptoms in patients with untreated OSAS seem to be associated with mucosal dryness. These symptoms improved during nCPAP treatment probably due to the change in breathing pattern. The occurrence of upper airway symptoms before nCPAP start did not predict long-term adherence to the treatment.

[Surgical techniques of the inferior nasal turbinates in the treatment of nasal obstruction]. / Alakuorikoihin kohdistuvat toimenpiteet nenän tukkoisuuden hoidossa.

Chronic nasal obstruction causes sleep disorders and has an adverse effect on quality of life. Inferior turbinate enlargement due to hypersensitive rhinitis is one of the main causes of chronic nasal obstruction. Many of these cases respond to topical corticosteroids. Long standing swelling may become irreversible and a surgical approach to enlarged turbinate becomes necessary. In septal deviation, a compensatory enlargement of contralateral inferior turbinate may indicate reduction at the time of septoplasty. A number of techniques for turbinate reduction have been described. Main target for the operation is submucosal soft tissue and less frequently bony tissue. Radiofrequency ablation, submucosal operation techniques and microdebrider techniques are the methods of choise in reducing inferior turbinate with diminished adverse side effects.

High Discontinuation Rates of Peroral ASA Treatment for CRSwNP: A Real-World Multicenter Study of 171 N-ERD Patients.

BACKGROUND: Nonsteroidal anti-inflammatory drug (NSAID) exacerbated respiratory disease (N-ERD) consists of chronic rhinosinusitis with nasal polyposis (CRSwNP), asthma, and NSAID intolerance. Acetylsalicylic acid treatment after desensitization (ATAD) is a treatment option for uncontrolled N-ERD. OBJECTIVE: To evaluate peroral ATAD's long-term effectiveness on CRSwNP disease control. METHODS: The retrospective data (patient characteristics, sinus surgeries before ATAD, ATAD, follow-up data [2019]) were collected from patient records of 171 patients with N-ERD (102 ATAD patients, 69 controls with CRSwNP+N-ERD without ATAD) who underwent tertiary hospital consultation from 2001 to 2017. Outcome measurements were ATAD discontinuation, revision sinus surgery, and corticosteroid and antibiotic courses for airway infections during 2016-2019. Associations were analyzed by survival and nonparametric methods. RESULTS: The ATAD group had more tissue eosinophilia, symptoms, and sinus surgeries before ATAD than others. The ATAD discontinuation rate was 63%, independent of ATAD dose or duration, usually due to side effects. Compared with the N-ERD group without ATAD, ATAD (mean duration, 2.9 years) did not affect the revision endoscopic sinus surgery rate (P = .21, by the log-rank test) or the number of peroral corticosteroid courses per year (P > .05, by the Mann-Whitney U-test) during the follow-up (mean, 7.6 years) despite the dose or duration of ATAD. CONCLUSIONS: The discontinuation rate of ATAD was high (63%), and ATAD did not affect revision sinus surgery rate nor the need of peroral corticosteroids during follow-up. However, the remaining 37% of the ATAD group did continue the treatment, indicating that they may have benefited from ATAD.

Practical Aspects of Interface Application in CPAP Treatment.

While continuous positive airway pressure (CPAP) is an effective first-line therapy for sleep apnea, CPAP fails in one third of patients mainly due to poor adherence to the CPAP device and masks. The role of the medical team is to guide the patient in choosing the best mask, thus insuring good CPAP therapy adherence. Once a suitable mask is found, the brand of the mask does not affect patient satisfaction or CPAP adherence. For the majority of patients, nasal masks are by far more suitable than oronasal masks. Orosanal masks are indicated in case of nasal stuffiness or when an air leak manifests through the mouth. Re-evaluation of the efficacy of CPAP therapy is recommended when switching to oronasal masks.

All snoring is not adenoids in young children.

OBJECTIVE: To determine the prevalence of snoring in young children and to assess age, growth, previous surgery therapy, respiratory problems and sleep-related symptoms in relation to child's snoring, and to evaluate the relationship between child's snoring and parents' snoring and smoking. CHILDREN AND METHODS: A cross-sectional study evaluated 2100 children 1-6 years of age in Helsinki, Finland. Child's frequency of snoring on a five-point scale (never to every night) and age, height, weight and body mass index, previous adenotonsillectomies, tympanostomies, allergic rhinitis and respiratory infections were determined as was frequency of parental snoring and smoking. Sleep problems were determined based on Finnish or Swedish modified version of the sleep disturbance scale for Children. RESULTS: Of the 2100 eligible children, 1471 (71%) returned questionnaires. Children always or often snoring numbered 92 (6.3%), sometimes snoring, 183 (12.4%), and never or occasionally snoring, 1196 (81.3%). No difference in age (p=0.06) or gender (p=0.39) existed between snorers and non-snorers. History of previous adenotonsillectomies (p<0.001), allergic rhinitis (p<0.001), recurrent respiratory infections (p<0.001), and otitis media (p<0.001) were more common among snorers than among occasional or never-snorers. Nocturnal symptoms such as breathing problems, sleep hyperhydrosis, sleep-wake transition disorders, and daytime somnolence were associated with children's snoring. Frequency of children's snoring was also associated with parental snoring (p<0.001) and smoking (p<0.001). CONCLUSIONS: Snoring is common among young children and is associated with previous adenotonsillectomy, allergic rhinitis, respiratory infections, nocturnal symptoms, and parents' snoring and smoking. The high prevalence of snoring among children with adenotonsillectomy raises the question whether adenotonsillectomy alone is adequate treatment for snoring in young children.

Snoring is not relieved by nasal surgery despite improvement in nasal resistance.

OBJECTIVES: In the present study, we evaluated the effect of nasal surgery on snoring time, snoring intensity, and sleep-disordered breathing. The role of abnormal cephalometry in treatment outcome was assessed. DESIGN: A cross-sectional prospective study. SETTING: University teaching hospital. PATIENTS: Forty consecutive snoring men who were referred to ENT Hospital because of a snoring problem or suspicion of sleep apnea. INTERVENTIONS: The patients underwent anterior rhinomanometry and polysomnography (PSG) with recording of snoring before and after operative treatment of nasal obstruction. Cephalometric radiographs were obtained before surgery. RESULTS: Nasal resistance decreased significantly in the overall patient group. Snoring time, snoring intensity, nocturnal breathing, and sleep architecture did not change after nasal surgery. Cephalometry did not predict operative outcome in these patients. Snoring intensity was found to be significantly higher during non-rapid eye movement (NREM) sleep than during rapid eye movement sleep. CONCLUSIONS: Operative treatment of mainly structural nasal obstruction did not seem to decrease snoring intensity, snoring time, or sleep-disordered breathing in an objective assessment by PSG performed after surgery. The effect of treating inflammatory nasal changes during nocturnal breathing, as well as the role of cephalometry in the prediction of treatment outcome will need further evaluation. Higher snoring intensity related to NREM sleep may add to the sleep disturbance of a bed partner in the evening.

Acoustic rhinometry in small children.

OBJECTIVES: To study how acoustic rhinometry succeeds in a sample of small children of one to six years of age and to evaluate reasons for failed recordings. METHODS: Twenty-six healthy children one to six years of age were invited to the Helsinki University Hospital, Department of Otorhinolaryngology for clinical examination and measurements with acoustic rhinometry. RESULTS: Three children of ten refused recordings in the age group of one to two years. The children's nose adaptor was too small for three of seven children in the age group of three to four years. The anatomical nose adaptor and the adult nose tube were suitable for children between five to six years of age. CONCLUSIONS: Acoustic rhinometry is well tolerated and usually well accepted in small children. The recordings succeeded in most children. However, lack of adequate equipment hinders measurements in part of the children.
