Abstract
BACKGROUND COVID-19 and other respiratory infections spread through aerosols produced in respiratory activities and in certain surgical procedures considered as aerosol-generating procedures (AGP). Due to manipulation of the upper airway mucosa, rhinosurgery has been considered a particular risk for spread of respiratory infections. Our aim was to assess staff exposure to aerosols during common rhinosurgical procedures METHODS: Staff exposure to generated particle concentrations and size distributions between 0.3 μm and 10 μm were measured during rhinosurgery using an optical particle sizer without any additional collection methods. Similarly measured aerosol exposure during coughing (a commonly used risk reference for aerosol generation) and the operating room's background concentration were chosen as reference values. RESULTS Altogether 16 common rhinological surgeries (septoplasties and endoscopic sinus surgery) were measured. The use of suction produced significantly lower aerosol concentration compared to coughing. Low aerosol generation was observed during injection anaesthesia of the nasal mucosa. Instrument comparison revealed that the microdebrider produced fewer aerosols than cold dissection in particles of 1-5 μm and >5 μm. CONCLUSIONS Common rhinosurgeries do not seem to generate as high aerosol concentration exposures as previously believed. Rather, the observed aerosol exposure is lower or similar to exposures during coughing. Therefore, the classification of common rhinosurgeries as AGPs should be re-assessed or possibly discarded.

Abstract
Background Developing tools to identify chronic rhinosinusitis with nasal polyps
(CRSwNP) patients requiring surgical treatment would help clinicians treat
patients more effectively. The aim of this retrospective cross-sectional
study was to identify cut-off values for eosinophil percentage, nasal
polyps (NP), and Lund-Mackay (LM) scores that may predict the need for
surgical treatment in Finnish CRSwNP patients. Methods Data of CRSwNP patients (N = 378) undergoing consultation for ESS in 2001–19
were used. Data was collected from patient records and Lund-Mackay scores
were determined from sinus computed tomography scans. The percentage of
eosinophils was microscopically evaluated from the polyp samples available
(n = 81). Associations were analyzed by Mann Whitney U test, and cut-off
values by the area under the receiver operating characteristic curve
(AUROC). Results ESS was performed to 293 (77.5%) of patients. Polyp eosinophilia was
associated significantly with ESS (p = 0.001), whereas peripheral blood
eosinophil count, LM- score and endoscopic NP- score were not (p > 0.05).
AUROC values (95% CI) for detecting those needing ESS were for polyp
eosinophilia 0.71 (0.60–0.83), p = 0.001, for LM score 0.59 (0.50–0.67),
p = 0.054; for NP score 0.56 (0.48–0.64), p = 0.17, and for blood eosinophil
count 0.68 (0.46–0.90), p = 0.08. With the threshold value of polyp
eosinophilia (>25%), the sensitivity and specificity were optimal for
detecting the group needing ESS from the group not undergoing ESS. The
cut-off value of blood eosinophil count (>0.26 × 109/L) had
relatively good, yet statistically insignificant (underpowered), predictive
potential. Moderate cut-off values were found for endoscopic LM score
(≥14/24) and NP score (≥4/8). Conclusions Polyp eosinophilia (>25%) predicted ESS among Finnish hospital-level
CRSwNP patients. A future challenge would be to find less invasive and
cost-effective clinical factors predicting uncontrolled CRSwNP.

Abstract
The first European Rhinology Research Forum organized by the European Forum for Research and Education in Allergy and Airway Diseases (EUFOREA) was held in the Royal Academy of Medicine in Brussels on 17th and 18th November 2016, in collaboration with the European Rhinologic Society (ERS) and the Global Allergy and Asthma European Network (GA2LEN). One hundred and thirty participants (medical doctors from different specialties, researchers, as well as patients and industry representatives) from 27 countries took part in the multiple perspective discussions including brainstorming sessions on care pathways and research needs in rhinitis and rhinosinusitis. The debates started with an overview of the current state of the art, including weaknesses and strengths of the current practices, followed by the identification of essential research needs, thoroughly integrated in the context of Precision Medicine (PM), with personalized care, prediction of success of treatment, participation of the patient and prevention of disease as key principles for improving current clinical practices. This report provides a concise summary of the outcomes of the brainstorming sessions of the European Rhinology Research Forum 2016.
