Phlegmon peri-amygdalien aspects diagnostiques et thérapeutiques

Introduction: The Peritonsillar abscesse (PTA) is a suppurated complication of the face and the neck often met as a matter of urgency ENT. He can raise diagnostic and therapeutic problems and be life-threatening. The objective of this study is to specify the epidemiological and clinical particularities of this affection and to revise the therapeutic possibilities from a review of the literature.PATIENTS AND METHODS: This retrospective study concerning 75 patients hospitalized for PTA in the Department of Otolaryngology-Head and Neck Surgery of the Hospital of Nabeul over a period of 7 years (in January 2001 to December 2007). The study of files allowed us to find all the clinical and therapeutic data. Our drop is of two years.RESULTS : The average age of our patients was of 26 years with a sex ratio of 1. The classic set of three of the PTA was complete only in 49 % of the cases. All the patients were the object of a needle aspiration, it was positive in 74 % among which 92 % benefited from a drainage under local anesthetic. A germ was identified in 16 cases with a Streptococcus â-hemolytic group A in 13 cases. The clinical and biological cure was noticed on average in the tenth day. Forty-seven patients underwent tonsillectomy at a later date after an interval from 2 to 6 months. No emergency tonsillectomy was realized.CONCLUSION : The Peritonsillar abscesses is a frequent urgency in ENT. The diagnostic is clinical. The practicable of needle aspiration in every case allows to confirm the diagnosis in the incomplete forms. The treatment is medical and surgical.KEYWORDS : Peritonsillar abscesses, diagnostic, treatmen

Adénome pléomorphe du septum nasal: À propos d’un cas

Introduction : L’adénome pléomorphe représente la tumeur la plus fréquente des glandes salivaires principales. Sa découverte au niveau des cavités nasales est rare et méconnue. Matériel et Méthode : Les auteurs se proposent de rapporter une observation originale d’AP du septum, et d’en préciser les particularités diagnostiques et thérapeutiques à partir d’une revue de la littérature. Résultats : Il s’agissait d’une fillette de 9 ans ayant consulté pour une obstruction nasale gauche d’aggravation progressive évoluant depuis 5 mois, accompagnée d’une rhinorrhée intermittente homolatérale. L’examen clinique et l’imagerie ( scanner avec IRM) retrouvaient une formation tissulaire comblant la cavité nasale gauche aux dépens du tiers antérieur du septum sans lyse osseuse. Nous avons effectué l’exérèse chirurgicale de la masse, par voie endonasale sous guidage endoscopique avec un examen anatomopathologique. Les suites opératoires ont été simples. En particulier, nous n’avons pas observé de récidive avec un recul d’un an. Conclusion : Bien que rare dans cette localisation, l’AP doit être évoqué devant toute formation de la fosse nasale. L’imagerie est indispensable. Le traitement est toujours chirurgical. Le diagnostic repose sur l’histologie. Les risques de récidive et de transformation maligne imposent une surveillance post-opératoire prolongée.Mots clés : Adénome pléomorphe, Septum nasal, Chirurgie

Fasciite nodulaire de la cavite buccale

Introduction: Nodular fasciitis is a benign tumour-like lesion characterized by fibroblastic proliferation. It is common in subcutaneous fascia, usually of the upper extremity but it's very rare in the oral cavity. Frequently misdiagnosed as sarcoma due to its rapid growth, rich cellularity and mitotic activity.Patients and Methods: One patient with an oral nodular fasciitis and a review of literature are reported in order to describe the diagnostic and therapeutic management of this tumour.Case presentation: A 50-year-old female with an intraorally swelling that had been growing progressively over one month. There was no history of trauma. Clinical examination revealed a firm mass palpable measuring approximately 4 cm in diameter. She had an excisional biopsy under local anaesthetic with histopathological analysis. The lesion was surgicalremoved under general anaesthesia through an intraoral approach. One year after excision of the tumour, the oral cavity was free of tumour.Conclusion: Nodular fasciitis is an entity characterized by rapid growth, rich cellularity and mitotic activity, although it is not malignant. It can only be diagnosed by histopathological examination of a biopsy with immunohistochemical staining.The treatment of choice is the complete surgical excision.Keywords: Nodular fasciitis, Oral cavity, Surgical treatment

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

Splitting Arabic Texts into Elementary Discourse Units

International audienceIn this article, we propose the first work that investigates the feasibility of Arabic discourse segmentation into elementary discourse units within the segmented discourse representation theory framework. We first describe our annotation scheme that defines a set of principles to guide the segmentation process. Two corpora have been annotated according to this scheme: elementary school textbooks and newspaper documents extracted from the syntactically annotated Arabic Treebank. Then, we propose a multiclass supervised learning approach that predicts nested units. Our approach uses a combination of punctuation, morphological, lexical, and shallow syntactic features. We investigate how each feature contributes to the learning process. We show that an extensive morphological analysis is crucial to achieve good results in both corpora. In addition, we show that adding chunks does not boost the performance of our system
