Hemangiomes Larynges De L\'adulte A Propos De 9 Cas

L\'hémangiome laryngé de l\'adulte est extrêmement rare et présente des spécificités histologiques et évolutives. Il peut représenter un véritable défi thérapeutique. Les auteurs rapportent 9 cas d\'hémangiomes laryngés de l\'adulte colligés rétrospectivement sur une période de 20 ans (1984- 2004). Il s\'agissait de 6 hommes et 3 femmes, âgés en moyenne de 46 ans (17 à 75 ans). Les signes d\'appel étaient la dysphonie dans tous les cas, associée à des hémorragies de sang rouge extériorisées par voie buccale chez 3 patients. Le diagnostic reposait dans tous les cas sur la laryngoscopie directe qui retrouvait une tuméfaction glottique de couleur bleutée, à surface lisse. Une biopsie avec examen anatomo-pathologique a été systématique. Tous les patients ont bénéficié d\'une exérèse instrumentale de la masse par voie endoscopique, avec hémostase locale. Deux récidives ont été notées, pour lesquels une seconde exérèse instrumentale par voie endoscopique a été réalisée avec une évolution favorable. Le recul moyen était de 9 ans.The adult laryngeal hemangioma is extremely rare and presents histological and evolutionary particularities. It can represent a real therapeutic challenge. The authors report 9 cases of adult laryngeal hemangiomas over a period of 20 years (1984-2004). It was about 6 man and 3 women, old on average of 46 years ( 17 - 75 years). The signs of appeal were the dysphonia in every case, associated to bleedings of red blood exteriorized with oral way in 3 cases. Diagnosis based in every case on the direct laryngoscopy which found a glottic tumefaction of bluish colour, in smooth surface. A biopsy with anatomo-pathological exam was realized in every case. All the patients benefited from an instrumental excision of the mass by endoscopic way, with local haemostasis. Two recurrences were noted, which benefited from a second endoscopic instrumental excision, with a favorable evolution. Average follow up was of 9 years.

Rubber Clay Nanocomposites

The use of nanofillers allows the development of nanocomposites with improved properties and novel applications. The technological goal is possible due to the new compounding method that allows a particle dispersion in the nanometer scale increasing the specific surface area.Fil: Cova Sánchez, Mariajose.

Pure mucinous carcinoma of breast cancer in 56 Tunisian women

Background: Pure mucinous carcinoma breast cancer (PMBC) is a relatively rare subtype cancer of breast malignancy and associated with favorable prognosis. This retrospective study aims to investigate clinical, pathological features and clinical long-term outcomes. Methods: A retrospective review of 56 patients' files with pure mucinous breast cancer was performed. We evaluated the clinic-pathologic characteristics and survival status. Results: The mean age was 59 years. 37 patients underwent modified radical mastectomy; 14 underwent breast-conserving surgery. The 5-years overall survival (OS) and disease free survival (DFS) rates were respectively 75,3% and 74%. According to univariate analysis for OS, age (p = 0,049), menopausal status (p = 0,024), clinical T stage (p = 0,037), N stage (p = 0,002) and pathological T stage (p = 0,033) were statistically significant factors for survival. The DFS was better in postmenopausal women (p = 0,02), histological tumor size smaller than 20 mm (p = 0,024), and negative lymph nodes (p = 0,049). Conclusion: Pure mucinous breast cancer has a favorable prognosis and is characterized by lower tumor grade, higher hormone receptor expression and lower incidence of nodal involvement. Thanks to its good prognosis, this subtype of cancer should be treated less aggressively than invasive ductal carcinoma
