Surgical and prosthetic treatment in an elderly patient affected by unilateral idiopathic gingival fibromatosis: a case report.

OBJECTIVES: The aim was to present the diagnosis and treatment of a case of unilateral idiopathic gingival fibromatosis (IGF) in a geriatric patient. BACKGROUND: IGF is a rare condition characterised by an enlargement of the attached and marginal gingivae with no obvious association to any causative factor. Gingival overgrowth causes inaesthetic changes and clinical symptoms such as speech disturbances, tooth movement, and occlusal problems. MATERIALS AND METHODS: A 65-year-old female presented localised enlargement of mandibular gingiva, malpositioning of anterior mandibular teeth, and difficulty in speech and mastication. IGF also causes numerous aesthetic and psychological problems. Treatment consisted of multiple extractions, surgical therapy, and early prosthetic rehabilitation to restore function and appearance and to prevent recurrence. RESULTS: Excellent aesthetic result and psychological benefit were achieved, and no fibromatosis recurrence was detected after 1 year following surgery. CONCLUSION: Gingival resection of the tissue excess and early oral rehabilitation with removable dentures have so far greatly improved patient's quality of life.

[Screening and prevention of tuberculosis, an experiment in Marseille]. / Dépistage et prévention de la tuberculose, une expérience à Marseille.

In order to apply the recommendations of the French High Council on Public Health (CSHPF), the association "Médecins du Monde" and the departmental centre for the fight against tuberculosis led; in 2010-2011, two campaigns for on-site screening, in Marseille, with Roma families in situations of precariousness. These campaigns came up against a number of difficulties which must be addressed in order to make them more effective.

Fe analysis by the ferrozine method: Adaptation to FIA towards in situ analysis in hydrothermal environment.

The target of this study is the adaptation of the ferrozine method to flow injection analysis (FIA) to perform iron analysis in situ using an in situ chemical analyser in hydrothermal environments. The adaptation of the method to FIA was followed by its optimisation using an experimental design screening method. The goals of the optimisation steps were to decrease the detection limit and to increase the measuring range to cope with the constraints of in situ analysis. The method allows the determination of iron in the mixing zone of hydrothermal fluid, enriched in iron, and seawater. A single manifold gives the possibility to analyse either Fe(II) or SigmaFe [Fe(II)+Fe(III)] in situ, or SigmaFe in the lab on hydrothermal seawater samples. The measuring range of the method was increased to up to 2000muM, which is coherent with the study of the chemical environment of communities associated with deep-sea hydrothermal activity. Finally, the method was applied in situ using the chemical analyser Alchimist during the ATOS cruise on hydrothermal vent fields on the Mid Atlantic Ridge.
