Resume Les dyskinesies ciliaires primitives (DCP) sont des maladies genetiques rares dues a des anomalies de structure et/ou de fonction des cils mobiles, responsables d’un defaut d’epuration muco-ciliaire. Ces dysfonctions ciliaires conduisent a des infections chroniques des voies aeriennes superieures et inferieures, de debut possiblement neonatal. L’evolution, de gravite variable, se fait vers une rhinosinusite chronique parfois invalidante et des bronchiectasies progressives, mais l’esperance de vie est consideree comme peu diminuee. Environ la moitie des patients presentent des anomalies de lateralisation des visceres pouvant alors s’inscrire dans la triade du syndrome de So (sinusite chronique, bronchiectasies, situs inversus). Une infertilite masculine est possible, par mobilite anormale du flagelle des spermatozoides dont la structure interne est tres proche de celle des cils mobiles. Le diagnostic repose sur la mesure du debit nasal de monoxyde d’azote et l’analyse de la fonction et de l’ultrastructure des cils respiratoires. La genetique des DCP est complexe du fait de l’heterogeneite des anomalies ciliaires et du grand nombre de genes impliques (45 genes impliques a ce jour). Les patients requierent un suivi multidisciplinaire regulier, clinique, microbiologique, fonctionnel et radiologique. La prise en charge au long court repose principalement sur le drainage nasal et bronchique quotidien et l’antibiotherapie, permettant de reduire la morbidite et de proteger le capital pulmonaire des enfants atteints de DCP.

Resume Objectifs Rediger un consensus formalise sur le management ORL associe a la chirurgie implantaire avec ou sans surelevation du plancher sinusien. Materiels et methodes La methodologie suit les regles de la Haute Autorite de sante : « Bases methodologiques pour l’elaboration de recommandations professionnelles par consensus formalise ». La methode choisie est dite RAND/UCLA (« RAND appropriateness method ») dans sa version courte. Resultats Il est recommande lors du bilan pre-implantaire de rechercher systematiquement une pathologie nasosinusienne a l’interrogatoire et de privilegier une imagerie tridimensionnelle (scanner ou cone-beam). Il est recommande d’inclure a l’imagerie la totalite du sinus maxillaire lorsque le patient ne presente pas d’antecedent nasosinusien ou de signes fonctionnels a l’interrogatoire. Dans le cas contraire, un examen de la totalite des cavites nasosinusiennes est recommande. Cette attitude permet simultanement de faire l’analyse de l’infrastructure du maxillaire pour le bilan pre-implantaire et de caracteriser l’etat de l’organe nasosinusien. Les incidentalomes muqueux sinusiens sont tres frequents dans la population saine, ils doivent etre confrontes au contexte clinique, endoscopique et radiologique. Conclusion Ce consensus formalise d’experts permet d’etablir un socle de connaissance commune, de clarifier les enjeux, les situations cliniques et d’homogeneiser les pratiques.

Objectives To draw up guidelines for ENT management associated with dental implant surgery with or without sinus lift. Materials and methods The methodology followed the rules of laid down by the French Health Authority (HAS): “Methodological bases for drawing up professional recommendations by formalized consensus”. The chosen method was the RAND/UCLA “RAND appropriateness method” (short version). Results In the pre-implantation check-up, it is recommended to systematically screen for sinonasal pathology on medical interview and to favor 3D CT or cone-beam imaging. It is recommended that imaging include the entire maxillary sinus when the patient does not have sinonasal history or functional signs on interview. Otherwise, examination of all sinonasal cavities is recommended. This attitude enables simultaneous analysis of maxillary infrastructure for pre-implantation work-up and assessment of sinonasal cavity status. Sinus mucosal incidentalomas are very common in the healthy population and must be assessed with reference to the clinical, endoscopic and radiological context. Conclusion This formalized expert consensus establishes a common base of knowledge, to clarify the issues and clinical situations and to standardize practices.

Aim Altered sense of smell and/or taste is a leading symptom of SARS-CoV-2 infection, but its prevalence at a population-level is unknown. Methods From a questionnaire addressed to a representative subset of the French general adult (≥ 18-year) population over a 6-week period during the first French lockdown (April 7 to May 19 2020), self-reported new cases of altered sense of smell and/or taste were collected. Results From 29,660 participants, new altered sense of smell and/or taste was 2.18% and 2.11% after direct standardization on the French population representing more than 1,110,000 subjects in France. Moreover, 0.5% of participants reported a positive SARS-CoV-2 test, among which 47.4% reported a newly altered sense of smell and/or taste. Male participants, younger ones together with those presenting with chronic condition had higher odds of reporting a newly altered sense of smell and/or taste. Conclusion This study provides an accurate estimate of new cases of altered sense of smell and/or taste in the general population at a nationwide level during the Covid-19 first wave.

Resume Ces conseils de bonne pratique concernant les indications et les modalites de la corticotherapie en ORL en periode d’epidemie COVID-19 ont ete rediges sous l’egide de l’Association francaise d’otologie et d’oto-neurologie (AFON) et de la Societe francaise d’ORL et de chirurgie cervico-faciale (SFORL). Il n’y pas actuellement de donnees suggerant un danger ou un benefice particulier des corticoides dans la COVID-19, et il convient donc, tant que cette question n’est pas tranchee, de limiter leurs indications aux tableaux cliniques les plus severes et pour lesquels il est bien etabli que ce type de traitements a un effet favorable sur l’evolution des symptomes. Dans les paralysies faciales aigues a frigore de grade V ou VI dans la classification de House Brackmann, une corticotherapie orale d’une semaine est recommandee. Dans les surdites brutales avec un deficit auditif superieur a 60 dB, une corticotherapie est la-aussi conseillee, soit sous la forme d’injections intratympaniques soit en cures orales d’une semaine. En rhinologie, il n’y a pas d’indication a une corticotherapie par voie generale dans le contexte actuel. En revanche, il est conseille aux patients de poursuivre leur corticotherapie locale en spray nasal ou par inhalation. L’instauration de traitements par sprays nasaux de corticoides reste possible s’il n’existe pas d’alternative. Enfin, il n’y aucune indication aux corticotherapies par voie generale ou locale dans les infections ORL bacteriennes.

Resume La rhinite allergique (RA) est une pathologie frequente dont la severite ou le mauvais controle peut aboutir a une alteration significative de la qualite de vie des patients. L’immunotherapie antiallergenique (ITA) constitue a l’heure actuelle le seul traitement etiologique susceptible de modifier l’histoire naturelle de la maladie allergique. Bien connue des allergologues, cette option therapeutique est encore insuffisamment maitrisee par les ORL. Cette mise au point basee sur les meta-analyses et les essais les plus recents souligne l’efficacite de l’ITA sur l’amelioration des symptomes de la RA et sur la reduction de la consommation des traitements medicaux (corticoides, antihistaminiques). L’ITA serait aussi susceptible de reduire le risque d’apparition d’un asthme et de nouvelles sensibilisations lorsqu’elle est introduite suffisamment precocement. Les analyses immunobiologiques montrent bien une modification du profil inflammatoire apres ITA en faveur d’une immunotolerance impliquant les lymphocytes T regulateurs et la production d’IgG. La voie sublinguale en gouttes apporte des resultats comparables a ceux de la voie sous-cutanee tout en proposant une utilisation plus simple reduisant le risque anaphylactique. Une standardisation des protocoles d’etude en termes de mesure de l’effet therapeutique et de gradation des effets indesirables est neanmoins necessaire pour ameliorer les etudes comparatives. Les formes sublinguales en comprimes plus recemment introduites constituent une reelle opportunite pour ouvrir le champ de l’ITA aux ORL dans la RA pollinique et prochainement la RA aux acariens.

• Idiopathic non allergic rhinitis (i-NAR) is a frequent cause of non-allergic rhinitis and associates nonspecific symptoms. There is no simple direct procedure to establish i-NAR diagnosis. • Diagnosis of i-NAR is currently based on an absence of a definite causal factor and a lack of evidence for IgE-mediated allergy by skin prick tests and allergen-specific serum IgE • Measurement of nasal compliance with acoustic rhinometry evaluates the vasomotricity-related deformability of the nasal mucosa. It has been already suggested that nasal compliance could be abnormal in i-NAR. • In this prospective case-controlled study of 42 patients with chronic rhinitis and 21 control patients, after topical decongestion, compliances in i-NAR group were significantly increased compared to allergic rhinitis (AR) and Control group (n=21) (p

International audience; La paralysie unilatérale du nerf récurrent peut être responsable d’une dysphonie et de troubles de la déglutition. La physiopathologie de l’apparition d’une dyspnée induite par une paralysie récurrentielle unilatérale n’est pas complètement élucidée. Notre hypothèse est que la fuite d’air au niveau glottique pourrait être responsable du développement d’un syndrome d’hyperventilation (SHV).ObjectifL’objectif de cette étude était de déterminer, chez les patients atteints de paralysie récurrentielle unilatérale, si la dyspnée pouvait être associée au SHV.Matériel et méthodesSur une période de 12 mois, tous les patients atteints de paralysie récurrentielle unilatérale permanente (> 6 mois) après thyroïdectomie se plaignant de l’apparition d’une dyspnée inexpliquée ont été explorés. Les tests suivants ont été réalisés : score de Nijmegen, test d’hyperventilation provoquée, gazométrie artérielle, épreuves fonctionnelles respiratoires et tests cardiaques. Le diagnostic de SHV a été posé si au moins deux critères étaient présents parmi les suivants : score de Nijmegen > 23 ; reproduction d’au moins 2 symptômes habituels lors du test d’hyperventilation ; pression télé-expiratoire en CO2 (PetCO2) < 30 mmHg ou < 90 % de la PetCO2 initiale après une période de récupération de 5 min à la suite d’une hyperventilation volontaire de 3 min.RésultatsDix patients sur 366 opérés d’une thyroïdectomie pour une maladie bénigne présentaient une paralysie récurrentielle unilatérale permanente et une dyspnée. Parmi les 10 patients inclus, chez 8 le diagnostic de SHV a été retenu lors du test d’hyperventilation provoquée sans dysfonctionnement cardiaque/pulmonaire.ConclusionEn résumé, cette étude est en faveur de l’implication du SHV dans la dyspnée associée à la paralysie récurrentielle unilatérale.

Background Primary ciliary dyskinesia (PCD) is an inherited otosinopulmonary ciliopathy in which respiratory cilia are stationary or dyskinetic. Digital high speed videomicroscopy (DHSV) is highly sensitive and specific for PCD diagnosis, but lacks standardization, particularly about the conditions for the storage of ciliated epithelial samples before ciliary functional analysis (CFA). Indeed, storage temperature and duration may impact ciliary function, but this has never been extensively studied. We aimed to evaluate the stability of ciliary function over time when nasal brushing samples are conserved either in the fridge (4 °C)or at room temperature (22 °C). Methodology Ciliated epithelial samples were obtained by brushing nasal from 9 healthy subjects. These samples were divided equally and conserved either at 4 °C or at 22 °C. Beating cilia were recorded using DHSV at 37 °C immediately, 3 hours and then 9 hours after sampling. CFA was assessed by ciliary beat frequency (CBF) and the % of normal ciliary beat pattern (CBP). Results There was no significant difference in CFA over time after sampling, regardless of the sample storage temperature ( Table 1 ). Conclusion This pilot study suggests that stability of CFA may be preserved during 9 hours after sampling, whatever if the sample is conserved at 4 °C or at 22 °C. Larger studies are needed to confirm these preliminary results notably in pathological conditions.

Allergic rhinitis is a common condition, with significant impact on quality of life depending on severity and quality of control. Allergen-specific immunotherapy (allergen-SIT) is the only known treatment able to alter the natural course of allergic rhinitis. Although well known to allergologists, it has yet to be fully adopted by the ENT community. This review, based on the most recent meta-analyses and clinical studies, shows that SIT significantly reduces symptoms and medication requirements (nasal corticosteroids, H1-antihistamines) in allergic rhinitis. It can reduce the risk of progression to asthma and, if initiated early enough, of developing new sensitizations. Immunobiological analysis shows an altered inflammatory profile following SIT, with immune tolerance involving T-regulatory lymphocyte induction and IgG production. Sublingual SIT with drops is as effective as subcutaneous SIT and is simpler to use, with less anaphylactic risk. Standardization of trial protocols in terms of treatment response assessment and side effect grading is recommended to improve comparative studies. Sublingual SIT with tablets has recently been introduced, providing a good opportunity for ENT practitioners to adopt the SIT approach in rhinitis triggered by allergy to pollens and, in the near future, to house dust mites.

Transmission electron microscopy (TEM) analysis of ciliary ultrastructure is classically used for the diagnosis of primary ciliary dyskinesia (PCD). We report our extensive experience of TEM analysis in a large series of patients in order to evaluate its feasibility and results. TEM analysis performed in 1,149 patients with suspected PCD was retrospectively reviewed. Biopsies (1,450) were obtained from nasal (44%) or bronchial (56%) mucosa in children (66.5%) and adults (33.5%). TEM analysis was feasible in 71.4% of patients and showed a main defect suggestive of PCD in 29.9%. TEM was more feasible in adults than in children, regardless of the biopsy site. Main defects suggestive of PCD were found in 76.9% of patients with sinopulmonary symptoms and in only 0.4% of patients with isolated upper and 0.4% with isolated lower respiratory tract infections. The defect pattern was similar in children and adults, involving dynein arms (81.2%) or central complex (CC) (18.8%). Situs inversus was never observed in PCD patients with CC defect. Kartagener syndrome with normal ciliary ultrastructure was not an exceptional condition (10.2% of PCD). In conclusion, TEM analysis is feasible in most patients and is particularly useful for PCD diagnosis in cases of sinopulmonary syndrome of unknown origin.

19. Obstrucción nasal crónica

J.-F. Papon
- Abstract
La obstruccion nasal cronica es un sintoma muy poco especifico que representa un motivo frecuente de consulta. El caracter cronico se confirma cuando la obstruccion nasal persiste de un modo permanente o intermitente durante mas de 3 meses. El proceso diagnostico consiste en una anamnesis exhaustiva dirigida a caracterizar con precision la obstruccion nasal, asi como los signos que se puedan asociar. La endoscopia nasal realizada por un medico otorrinolaringologo es la primera exploracion que debe solicitarse en caso de duda diagnostica, sobre todo si se sospecha un tumor. La sintesis de la anamnesis y la exploracion fisica permite distinguir cuatro tipos de etiologias que se asocian en ocasiones: cuerpos extranos de las fosas nasales, tumores rinosinusales, enfermedades de la mucosa rinosinusal y malformaciones de la estructura osteocartilaginosa. Siempre debe recordarse que una obstruccion nasal puede ser el signo de revelacion de un tumor maligno rinosinusal, lo que, en caso de duda (exposicion al aserrin, dolor craneofacial, epistaxis, deformacion facial, trastornos visuales, anestesia facial, fracaso del tratamiento antibiotico) justifica la realizacion de una endoscopia nasal y una tomografia computarizada del macizo facial.

Nasal valve collapse is a dynamic abnormality that is currently diagnosed purely on the basis of clinical features and thus subject to certain interpretation. The aim of this study was to develop a new and reliable functional test to objectively characterize nasal valve collapse. This was an observational prospective study including consecutive patients referred to our center for exploration of chronic nasal congestion. The patients were classified into two groups according to their symptoms and clinical abnormalities: the nasal valve collapse (NV+) group when nasal valve collapse was clinically detected during moderate forced inspiration and/or when the feeling of nasal congestion improved during passive nasal lateral cartilage abduction (n = 32); and the no-nasal valve collapse (NV-) group for the others (n = 23). All patients underwent nasal functional tests (posterior rhinomanometry and acoustic rhinometry) before and after topical nasal decongestion. We compared the difference between the pressure flow of the inspiratory and expiratory phases during posterior rhinomanometry [flow rate inspiratory-expiratory difference (FRIED) test] between the two groups. The difference between the absolute value of inspiratory and expiratory flow was significantly higher in the NV+ group than in the NV- group both before and after topical decongestion. The cutoff value for the FRIED test was -0.008 l/s with a good sensitivity (82%) and a specificity of 59%. We suggest that the FRIED test constitutes an objective and easy-to-apply technique to diagnose nasal valve collapse in daily practice.

International audience; Cilia are slender, microscopic, hair-like structures or or-ganelles that extend from the surface of nearly all mam-malian cells. Motile cilia, such as those found in the lungs and respiratory tract, present a beating motion that keep the airways clear of mucus and dirt. They are thus of primary importance in many respiratory diseases. The performance of mucous transportation in the nasal cavity can be represented by a ciliary beating frequency. In this paper, we propose a fully automated method that computes the beating frequency from a sequence of images taken with high-speed videomi-croscopy. The advantage of our approach is its capacity in computing regionalized frequencies, i.e., various frequencies each associated with one region in the image. Moreover we propose a preprocessing pipeline to alleviate acquistion artefacts due to the camera or to the cell proper motions. We demonstrate the robustness of our approach, and illustrate its performance in comparison to the state-of-the-art.

Pulmonary and Respiratory Medicine - Abstract
Introduction Les dyskinesies ciliaires primitives (DCP) sont un groupe de maladies genetiques rares responsable d’une anomalie du mouvement des cils respiratoires. Le diagnostic est classiquement confirme grâce a l’identification d’une anomalie de l’ultra-structure ciliaire par microscopie electronique a transmission. L’analyse genetique ne peut etre proposee en premiere intention, etant donne le nombre (> 30 genes) et la taille (> 80 exons) des genes impliques. Nous avons souhaite etudier si la mesure objective du mouvement ciliaire par video-microscopie a haute vitesse pourrait predire le phenotype ultra-structural et ainsi guider l’analyse genetique. Methodes Nous avons prospectivement inclus 75 patients ayant un diagnostic certain de DCP, presentant un des 5 principaux phenotypes ultra-structuraux identifie par microscopie electronique (15 patients par groupe), et pour lesquels tous les genes correspondants ont ete sequences. L’etude du mouvement ciliaire a inclus le pourcentage de cil battant, la frequence de battement ciliaire, une evaluation qualitative et la mesure quantitative de 12 parametres du mouvement ciliaire. Resultats L’absence combinee des bras de dyneine externe et interne induit une immobilite ciliaire totale, quel que soit le gene implique. L’absence de bras de dyneine externe permet un rare mouvement ciliaire residuel avec une frequence de battement effondre en rapport avec un allongement du temps de pause, notamment en cas de mutation de DNAH1. L’absence de bras de dyneine interne avec desorganisation axonemale induit un faible pourcentage de cil battant avec une diminution de l’angle de battement, associe en cas de mutation de CCDC39 a une frequence maximale de battement augmentee. L’absence de complexe central permet un mouvement ciliaire relativement conserve, malgre une minorite de cil presentant un mouvement ciliaire circulaire, quel que soit le gene implique. Dans les DCP avec ultra-structure normale, les parametres de mouvement ciliaires ont des valeurs particulierement heterogenes, malgre une frequence de battement ciliaire augmentee avec une frequence maximale extreme. Conclusion L’analyse quantitative du mouvement ciliaire par video-microscopie a haute vitesse permet l’identification de parametres objectifs caracteristiques du phenotype ultra-structural des DCP.

The characteristics of sinus fungal ball (SFB), classically considered being a non-invasive form of fungal infection, in patients with host factors for invasive fungal infection (IFI) are unknown.To characterize SFB and their management in patients with host factors for IFI.Retrospective single-centre study of the clinical, radiology, histology and mycology records of patients treated for SFB between 1997 and 2007. Patients with and without host factors for IFI were compared.One hundred eighty one patients were classified into two groups: 19 (group 1) with and 162 (group 2) without host fac- tors for IFI. In group 1, SFB were asymptomatic in 26.3% of the cases, ethmoido-sphenoidal sinuses were more frequently involved than in group 2 and fungal culture was positive in 37.5% of the cases. The main species was Aspergillus sp. in both groups. Four cases of complicated SFB were observed, only in patients of group 1. Cure without recurrence was obtained in both groups by endonasal surgery, combined with triazole therapy in complicated forms with osteolysis.In patients with host factors for IFI, SFB more frequently involves deep sinuses and can be complicated by clinical signs suggestive of invasion and radiological signs of osteolysis, with no histological evidence of fungal invasion.

Centrioles, cilia, and flagella are ancestral conserved organelles of eukaryotic cells. Among the proteins identified in the proteomics of ciliary proteins in Paramecium , we focus here on a protein, Bug22p, previously detected by cilia and basal-body high-throughput studies but never analyzed per se . Remarkably, this protein is also present in plants, which lack centrioles and cilia. Bug22p sequence alignments revealed consensus positions that distinguish species with centrioles/cilia from plants. In Paramecium , antibody and green fluorescent protein (GFP) fusion labeling localized Bug22p in basal bodies and cilia, and electron microscopy immunolabeling refined the localization to the terminal plate of the basal bodies, the transition zone, and spots along the axoneme, preferentially between the membrane and the microtubules. RNA interference (RNAi) depletion of Bug22p provoked a strong decrease in swimming speed, followed by cell death after a few days. High-speed video microscopy and morphological analysis of Bug22p-depleted cells showed that the protein plays an important role in the efficiency of ciliary movement by participating in the stroke shape and rigidity of cilia. The defects in cell swimming and growth provoked by RNAi can be complemented by expression of human Bug22p. This is the first reported case of complementation by a human gene in a ciliate.

To subjectively evaluate the efficiency and tolerance of polypectomy using the microdebrider followed by local corticosteroids in nasal polyposis (NP) after medical therapy failure.Between 2000 and 2003, a polypectomy using the microdebrider was performed in 24 patients with NP. Efficiency was evaluated retrospectively by comparing pre- and postoperative functional and polyp scores. Efficiency was also evaluated regarding extension of NP on preoperative computed tomography (CT). Overall satisfaction was evaluated using a standardized phone questionnaire.Mean follow-up was 23.6+/-12.5 months. The overall and individual functional scores and the anatomical score were very significantly improved after polypectomy using the microdebrider. Extension of NP on preoperative CT was not related to polypectomy efficiency. Among the patients surveyed, 87.5% were globally satisfied, 73% considered the operative conditions as satisfactory, and 83% qualified the postoperative period as simple.Polypectomy using the microdebrider followed by local corticosteroids appears to be an efficient and well-tolerated treatment for improving functional symptomatology of patients with NP.

But de la presentation Les patients atteints d’un syndrome du nez vide (SNV) se plaignent souvent d’une dyspnee chronique, pouvant potentiellement correspondre a un syndrome d’hyperventilation (SHV). L’objectif principal de ce travail est d’evaluer la prevalence du SHV chez les patients presentant un SNV. Materiel et methodes Cette etude prospective monocentrique a inclus successivement tous les patients majeurs presentant un syndrome du nez vide de septembre 2013 a avril 2014. Dans un contexte de chirurgie endonasale anterieure (turbinoplastie, turbinectomie, septoplastie ou meatotomie),le SNV etait defini par i/deux des symptomes suivants : obstruction nasale paradoxale, douleur nasale, sensation de vide nasale, secheresse nasale ou pharyngee, ii/sans image sinusienne scannographique pouvant expliquer ces symptomes, iii/sans resistances uninasales elevee ( 2 (PetCO 2 ) apres 3 minutes d’hyperventilation suivie de 3 minutes de repos 2 de repos). En cas de positivite du test d’hyperventilation, un bilan comprenant des explorations fonctionnelles respiratoires, une radiographie de thorax et une mesure de VO 2 maximale etaient realises pour ecarter les autres causes de dyspnee, notamment cardio-pulmonaire. Le diagnostic de SHV etait retenu si ces derniers examens etaient normaux. Resultats Sur les 12 patients atteints d’un SNV inclus jusqu’en avril 2014, 9 avaient un test d’hyperventilation positif, soit une prevalence de 75 %. Dans ce groupe 5 patients avaient des manifestations cliniques attribuables au SHV avec un score de Nijmegen superieur a 23. Parmi les 3 autres patients, un presentait un trouble diffusif pulmonaire secondaire a un tabagisme sevre et deux ne se plaignaient pas de dyspnee. Conclusion Ces resultats preliminaires evoquent une prevalence elevee (75 %) du SHV chez les patients atteints de SNV. Les symptomes du SHV laissent penser qu’ils pourraient partager, en partie, une physiopathologie commune avec le SNV.

But de la presentation La dyskinesie ciliaire primitive (DCP) est une maladie genetique rare caracterisee par des anomalies ciliaires alterant la clairance mucociliaire. Les manifestations cliniques ORL sont bien connues chez les enfants mais la prevalence des symptomes et la description clinique sont mal connues chez les adultes. L’objectif de cette etude est de decrire l’atteinte ORL de la DCP chez l’adulte. Materiel et methodes Etude retrospective multicentrique sur 64 patients ayant une DCP confirmee par etude ciliaire et/ou genetique. Les patients etudies ont eu un examen ORL standardise (avec endoscopie nasale), une audiometrie + tympanometrie, des prelevements bacteriologiques des secretions nasales et un scanner des sinus. Resultats L’echantillon etudie comptait 63 % d’hommes, un âge median de 37 ans et 34 % de syndrome Kartagener. La consanguinite etait retrouvee dans 30 % des cas. Des antecedents de rhinosinusite et d’otite seromuqueuse (OSM) etaient presents chez 98 % et 73 % des patients, respectivement. La rhinorrhee (95 %) et l’hypoacousie (53 %) sont les principales plaintes. L’endoscopie nasale a montre une rhinosinusite chronique dans 60 % et des polypes dans 34 % des cas. Une OSM a ete diagnostiquee chez 48 % et une surdite de perception dans 15 % des cas. L’etude bacteriologique endonasale a montre la presence d’ Haemophilus influenzae , de Streptococcus pneumoniae et de Pseudomonas aeruginosa dans 28 %, 19 % et 19 % des cas, respectivement. Le scanner des sinus montrait des hypoplasies/agenesies sinusiennes dans 83 % des cas. Conclusion La DCP chez les adultes est caracterisee par l’importance des manifestations rhinosinusiennes. L’OSM reste cependant frequente et une surdite de perception n’est pas rare.

But de la presentation Le larynx joue un role dans la respiration par regulation de la pression intra pulmonaire. La paralysie recurrentielle (PR) unilaterale peut s’associer a des symptomes respiratoires du fait d’une diminution de la pression sous glottique et d’une fuite glottique. Ces symptomes sont varies, peu etudies et pourraient correspondre a un syndrome d’hyperventilation (SHV). Le SHV est un ensemble de symptomes induits par une hyperventilation physiologiquement inappropriee, reproductible et volontaire. Le but du travail est de rechercher si le SHV pourrait etre la cause des dyspnees chroniques inexpliquees chez des patients ayant une PR unilaterale post chirurgicale. Materiel et methodes Une recherche de SHV par questionnaire de Nijmejjen et test d’hyperventilation avec mesure de la pression du CO 2 en fin d’expiration (PETCO 2 ) a ete realise prospectivement dans une serie de 8 patients ayant une PR unilaterale iatrogene (chirurgie thyroidienne) de plus de 3 mois et se plaignant de symptomes respiratoires a type de dyspnee chronique avec intolerance a l’effort. Des explorations respiratoires et cardiaques ont ete realisees pour rechercher une autre cause de dyspnee chronique. Resultats Parmi les 8 patients testes, 2 patients ont ete exclus car l’un presentait une cardiomyopathie hypertrophique et l’autre un trouble ventilatoire mixte. Parmi les 6 patients inclus, 3 avaient un score superieur a 23/64 au questionnaire de Nijmejjen, faisant suspecter un SHV. Finalement, le diagnostic de SHV etait confirme chez 5 patients dont le test d’hyperventilation etait positif (i. e. PETCO 2 apres 3 minutes d’hyperventilation + 3 minutes de repos 2 de base). Conclusion Cette etude pilote montre que le SHV peut etre evoque chez les patients ayant une PR unilaterale et se plaignant d’une dyspnee inexpliquee. Une etude a plus large echelle serait necessaire afin d’evaluer l’incidence du SHV au cours de la PR. L’interet de ce travail permettrait de proposer un traitement simple et efficace du SHV, reposant sur la kinesitherapie respiratoire avec readaptation a l’effort.

Results There was no recent history of throat infection in patients or their relatives. Compliance to SSI preventive measures (pre operative showers, skin antisepsis, and laminar air flow) was adequate, and wearing of mask in the OR was adequate for 88% of 332 HCWs. A GAS isolate was recovered from throat swabs of 2 of the 6 HCWs caring for the 1 case, one of which was identical to the patient’s isolate. Auditing this HCW revealed a lack of adequate fitting of the mask during preparation of the OR. Educational sessions were implemented. After the 2 case occurred, the same HCW was again found colonized with a GAS isolate identical to the patient’s isolate, but different from the 1 one. A more in-depth investigation revealed that one of his children had recurrent tonsillitis. Decolonization of the HCW was attempted, but GAS carriage recurred until tonsillectomy was performed on his child.
