How Challenging is the 'Scaling Up' of Orthopaedic Simulation?

Innovation remains a major key to advance research and to develop new techniques. It is an essential need to speed up the valorization of scientific discovery in concrete and rapid implementation for the benefit of patients. Innovation involves collaboration between multidisciplinary researchers because it should enable knowledge transfer in both direction

La dysplasie fibreuse du rocher

La dysplasie fibreuse est une affection bénigne rare dont l’étiologie est inconnue. Elle représente une anomalie dans le développement normal de l’os. L’os temporal est rarement atteint, donnant des complications telles qu’une surdité et une paralysie faciale périphérique. L’imagerie, principalement la tomodensitométrie est capitale pour le diagnostic positif. On rapporte un cas de dysplasie fibreuse retrouvé chez une femme de 43 ans présentant une surdité brutale.Mots clés : os temporal, dysplasie, scanner.Fibrous dysplasia is an uncommon benign disorder of unknown etiology. It most likely represents a disorder of bone normal development. The temporal bone is rarely involved, giving complications such as hearing loss and facial nerve palsy. The imaging, mainly performed with computerized tomography, plays a major role in positive diagnosis. We report a case of fibrous dysplasia found on a 43 year-old women presenting an acute sensorineural hearing loss.Key words: temporal bone, dysplasia, CT

Le syndrome de pourfour du petit : une manifestation rare des cellulites cervico-mediastinales

Le syndrome de Pourfour du Petit (SPdP) relève de diverses étiologies. Nous rapportons le premier cas de SPdP secondaire à une cellulite cervico-médiastinale, a travers lequel nous décrivons l’étiopathogénie, la présentation clinique et les aspects évolutifs de cette entité clinique rare. un homme de 37 ans a été hospitalisé pour cellulite cervico-médiatinale. Outre le blindage inflammatoire cervical, l’examen a objectivé une mydriase gauche associée à une exophtalmie et un élargissement de la fente palpébrale d’installation récente. Le reste de l’examen neurologique et ORL a été sans particularité. Nous avons retenu le diagnostic du SPdP d’origine infectieuse. Le patient a été mis sous antibiothérapie et a eu un drainage et nettoyage de toute la loge viscérale cervicale et du médiastin supérieur. L’évolution a été favorable avec régression partielle des signes ophtalmiques. Le syndrome de Pourfour du Petit est une entité rare. Sa connaissance offre au clinicien des pistes diagnostiques notamment dans les pathologies mettant en jeu le pronostic vital.Mots clés : syndrome de Pourfour du Petit, système nerveux sympathique cervical, mydriase.The Pourfour de Petit syndrome (PdPS) is of various etiologies. We report the first case of SPdP secondary to cervicomediastinal cellulitis through which we describe the etiopathogeny, clinical presentation and evolution aspects of this rare clinical entity. A 37 years old male was hospitalized for cervico-mediastinal cellulitis. Besides the cervical inflammation, examination objectified a recent left mydriasis, exophthalmia and a widening of the palpebral fissure. The rest of the neurological examination was unremarkable. We retained the diagnostic of PdPS of an infectious origin. Beside antibiotherapy, the patient had drainage and cleaning of the visceral lodge and upper mediastinum. The evolution was favorable with partial regression of ophthalmic signs. The PdPS is a rare entity. its knowledge provides the clinician with diagnostic tracks including diseases involving lifethreatening.Key words : Pourfour du Petit syndrome, cervical sympathetic system, mydriasi

Esthesioneuroblastome : dilemme diagnostic et challenge therapeutique

Introduction : L’esthésioneuroblastome est une tumeur maligne rare des fosses nasales. Il s’agit d’une tumeur agressive et récidivante dont le traitement est controversé. Notre objectif est de décrire les particularités diagnostiques et les actualités thérapeutiques de cette tumeur.Matériels et méthode : Etude rétrospective sur une période de 10 ans (2001-2010), ayant intéressé trois cas d’esthésioneuroblastome colligés dans notre service.Résultats : Il s’agit de 3 patients âgés respectivement de 23, 30, 85 ans. Les signes fonctionnels sont l’obstruction nasale, l’épistaxis et les céphalées. L’endoscopie nasale a trouvé un processus tumoral endonasal dans tous les cas. Des adénopathies cervicales ont été retrouvées dans un cas. Le scanner du massif facial et la biopsie tumorale, réalisés dans les trois cas, ont permis de classer la tumeur respectivement aux stades B, C, A, selon la classification de KADISH. L’association chirurgie- radiothérapie a été préconisée dans deux cas et chimio-radiothérapie dans un cas. L’évolution a été favorable dans 2 cas. Le troisième patient a été perdu de vue.Discussion : le diagnostic d’esthesioneuroblastome est souvent tardif. L’imagerie est indispensable pour l’orientation de la stratégie thérapeutique. L’association chirurgie radiothérapie constitue le traitement de référence. La chimiothérapie gagne de plus en plus d’intérêt.Mots Clés: Esthésioneuroblastome; traitement; chirurgie; radiotherapie; chimiotherapie; pronosticIntroduction : Esthesioneuroblastoma is a rare malignant tumor of the nasal cavity. It is an aggressive tumor, associated with a high level of recurrence. Treatment is still controversial. The object of our report is to describe the clinical presentations and new therapeutic approaches of this tumor.Material and methods : We retrospectively reviewed three patients with nasosinusal esthesioneuroblastoma who were managed during a period of 10 years (2001- 2010).Results : the three patients were aged respectively of 23, 30 and 85 years. Functional signs were mainly nasal obstruction, epistaxis and headache. Nasal endoscopy found an endonasal tumor process in all cases. Cervical lymph nodes were noted in one case. The CT scann and the tumor biopsy were performed in all three cases. Esthesioneuroblastoma was classified, respectively in stage B, C and A, according to KADISH classification. The association surgery-radiotherapy has been advocated in both cases and chemo-radiotherapy in one case. The outcome was favorable in two cases. The third patient was lost to view.Discussion : The ENB is a rare neuroepithelial cancer of the nasal cavity. Its diagnosis is often delayed due to its nonspecific clinical presentation. Radiography is of a great contribution for the diagnosis and for guiding the therapeutic strategy. Surgery and radiotherapy are currently the recommended treatment modality. Chimiotherapy is a new therapeutic approach.Key Words : Esthesioneuroblastoma; treatement; surgery; radiotherapy; chimiotherapy prognosis

Mucocèle sphénoïdale bilatérale : a propos d’un cas

Les mucocèles sphénoïdales sont des formations pseudokystiques expansives, d’évolution lente, qui se développent au sein de la cavité sinusienne sphénoïdale. Elles possèdent la capacité d’éroder les parois osseuses et présentent une évolution pseudotumorale. Les rapports neuroméningés et orbitaires font la gravité de cette localisation sinusienne  la présentation clinique qui est souvent d’apparition retardée par rapport à la constitution de la mucocèle. L’imagerie (TDM et IRM) permet le diagnostic positif et le diagnostic différentiel avec certains processus développés au niveau de l’étage moyen de la base du crâne. La marsupialisation chirurgicale par voie endoscopique endonasale permet l’effondrement de la mucocèle.Mots-clés : mucocèle, sinus sphénoïda

Evaluation of a pilot consultation for maternity protection at work in Switzerland.

Switzerland's Labour Law and its Ordonnance on Maternity Protection aim to protect the health of pregnant employees and their unborn children while enabling them to continue to pursue their professional activities. Some companies encounter difficulties implementing the law's provisions. The Department of Occupational and Environmental Health, part of the Center for Primary Care and Public Health (Unisanté), has provided specialist occupational medicine consultations for pregnant employees since 2015. This study aimed to evaluate how well Swiss' maternity protection legislation is implemented by examining a list of relevant indicators measured during the occupational health consultation. The study also sought to investigate the consultation support provided to the relevant stakeholders and the adjustments made to pregnant employees' working conditions. Descriptive variables and indicators relative to the application of the Swiss maternity protection legislation for 83 pregnant employees were collected during the consultation's pilot phase (between 2015 and 2016). Descriptive statistics and cross-analyses of these indicators were made. Most pregnant employees faced multiple exposures to occupational risks. Preventive risk analyses were rare. Few adjustments to workstations were proposed. We found a tendency for employees to leave their workstations early on in their pregnancies due to sick leave certificate prescriptions. Specialist consultation and collaboration with occupational health physicians to recommend interventions for pregnant employees can provide significant benefits and help some pregnant women to continue at their workstations with appropriate adjustments. A specialised occupational health consultation is a useful instrument for identifying occupational hazards for both the pregnant woman and her unborn child. It is also an opportunity to explain employers' legal responsibilities and obligations to safeguard the health of their pregnant employees and to give specific advice for their company's situation. This consultation also enables employers to maintain their employees' valuable professional competencies in the workplace for as long as possible. Finally, occupational health consultation helps and supports healthcare providers who must, according to the law, make decisions about whether pregnant employees can continue working safely or not

Diagnostic Performances of an Occupational Burnout Detection Method Designed for Healthcare Professionals.

We aimed to assess the validity (criterion and cross-cultural validity) and reliability of the first occupational burnout (OB) detection tool designed for healthcare professionals in Belgium in the context of Swiss medical practice. First, we assessed the sensitivity and specificity of the Tool. We developed this tool based on the consultation reports of 42 patients and compared its detection to the results of the Oldenburg Burnout Inventory (OLBI), filled-in by patients before a consultation. Second, we performed an inter-rater reliability (IRR) assessment on the OB symptoms and detection reached by the Tool between a psychiatrist, two psychologists, and an occupational physician. The Tool correctly identified over 80% of patients with OB, regardless of the cutoff value used for OLBI scores, reflecting its high sensitivity. Conversely, its specificity strongly varied depending on the OLBI cutoff. There was a slight to fair overall agreement between the four raters on the detection of OB and the number of OB symptoms. Around 41% of symptoms showed a substantial to an almost perfect agreement, and 36% showed a slight to a moderate agreement. The Tool seems useful for identifying OB of moderate and strong severity in both the Belgian and Swiss contexts

Dacryocystostomies par voieendonasale:indications et technique chirurgicale

Introduction : La dacryocystorhinostomie consiste à dériver le contenu du sac lacrymal directement vers la lumière de la fosse nasale correspondante en réalisant une large ouverture dans la paroi osseuse et muqueuse du sac, court-circuitant ainsi le canal lacrymonasal obturé. nous nous proposons, à travers cette étude rétrospective, de discuter les aspects techniques chirurgicaux de la dacryocystostomie par voie endonasale et de revoir les indications opératoires.Mots-clefs : dacryocystite ; dacryocystorhinostomie ; chirurgie endonasaleThe purpose of dacryocystorhinostomy is to derive the content of the lacrimal sac directly into the light of the corresponding nasal cavity by making a large opening in the bony wall and sac mucosa, by passing the blocked nasolacrimal duct. We intend, through this retrospective study, discuss the technical aspects of surgical dacryocystostomy by endonasal and review the indications for surgery.Keywords : dacryocystitis; dacryocystorhinostomy; endonasal surgery

Evolution of gynaecologists' practices regarding the implementation of Swiss legislation on maternity protection at work between 2008 and 2017.

In accordance with the International Labour Organization’s Maternity Protection Convention (No. 183) and European Union Directive 92/857CEE (1992), Switzerland’s Labour Law and its Maternity Protection Ordinance (OProMa) aim to protect the health of pregnant employees and their future children while enabling them to pursue their working activities. Gynaecologists-obstetricians have a key role in this legislation, particularly through the prescription of preventive leave for patients who would otherwise face dangerous or arduous tasks in the absence of an adequate risk analysis or suitable protective measures. However, international and national literature suggests that gynaecologists-obstetricians may encounter difficulties in fulfilling their role. This study aimed to: (1) describe the practices and difficulties encountered by gynaecologists-obstetricians in the practical implementation of the OProMa; and (2) compare the evolution of these practices and difficulties between 2008 and 2017. A survey by questionnaire was conducted in 2008 and repeated in 2017. Both surveys focused on gynaecologists-obstetricians working in the French-speaking part of Switzerland (in private practices, hospitals or both). Descriptive and comparative analyses were carried out. 83 gynaecologists-obstetricians responded in 2008 and 93 in 2017: response rates of 47% and 32%, respectively. In 2017, gynaecologists-obstetricians were more likely to ask questions about occupational risks faced by their patients when consulted by working mothers about their pregnancies. The estimated percentage of patients exposed to an occupational risk remained constant (20% in 2008 and 22% in 2017). Communication and collaboration with employers were reported to be difficult in both surveys, even though these are key elements in the implementation of the OProMa. Collaboration with occupational physicians, however, was more frequent in 2017. In 2017, gynaecologists-obstetricians showed a greater awareness of occupational risks and collaborated more frequently with occupational health specialists. However, the application of the OProMa remained limited over the studied time period. Improving training of gynaecologists-obstetricians in this field could be a significant factor in encouraging better implementation of the current legislation. Moreover, gynaecologists-obstetricians need to be given the necessary support to enable their clinical practice to evolve towards a more preventive type of medicine. Collaboration with relevant stakeholders, including occupational physicians, midwives and workers, should be encouraged

Épicondylalgies latérales dans une cohorte de salariés ligériens : évolution et déterminants

Objectifs Il n’existe que peu d’éléments concernant le pronostic à long terme des épicondylites latérales en population salariée en général. L’objectif a été d’écrire l’évolution et les déterminants des douleurs du coude et des épicondylalgies latérales vraisemblables dans une cohorte de salariés représentative de la population française au travail. Méthode Des salariés ligériens présentant entre 2002 et 2004 une épicondylalgie latérale vraisemblable ont été suivis pour connaître l’évolution de leurs symptômes quatre ans après (2007 et 2009). Les déterminants possibles de la pathologie ont été étudiés. Résultats Sur les 1611 salariés suivis, 100 sujets présentaient une épicondylalgie latérale vraisemblable en 2002–4. Plus d’un tiers des salariés inclus (39,0 %) présentaient une douleur au coude ou une épicondylalgie lors du second examen. Les travaux sollicitant le coude sont significativement associés à la persistance des épicondylalgies latérales vraisemblables en uni- et multivariée (odds ratio ajusté 5,59 [1,47 ; 21,30]). Conclusion Les épicondylalgies latérales en milieu professionnel évoluent favorablement dans deux tiers des cas environ. Cette évolution dépend du diagnostic et de la prise en compte des facteurs professionnels dans la prise en charge. La déclaration de maladie professionnelle n’apparaît pas comme un déterminant indépendant significatif de mauvais pronostic même si le praticien doit évaluer les avantages et les inconvénients d’une telle démarche et en informer le patient
