Background: This study aimed to characterize and test the antimicrobial susceptibility of Lactococcus lactis isolated in endodontic infections in Burkina Faso. Material and methods: This was a prospective study conducted at the Municipal Oral Health Center of Ouagadougou, Burkina Faso, from June to October 2014. Clinical data were collected using a questionnaire form. The method of streaking on selective medium was used to isolate bacteria. Identification was made using the API 20 Strep gallery. Antibiotic susceptibility was performed by the diffusion method on solid medium. Results: One hundred and twenty-five (125) patients were received with a significant proportion from the age group of 19 to 40 years (55.2%). Apical periodontitis accounted for 50.4% and cellulitis for 49.6% of cases. Lactococcus lactis ssp. lactis was identified in five exudate samples. Isolates were 100% resistant to cefixime and metronidazole, 80% to ceftriaxone, cefuroxime, cefotaxime, chloramphenicol and 60% to penicillin G, amoxicillin, amoxicillin clavulanic acid. A multidrug resistance of more than three families of antibiotics was noticed. No strains produced extended spectrum ß-lactamases. Conclusion: Lactococcus lactis is part of endodontic biofilm. The reported strong antibiotic resistance involving endodontic therapy will focus on the effect of the disinfectant solution and the mechanical action of the canal instruments.
In some developing countries wire is still widely used in facial fractures internal fixation. This study presents the effectiveness and complications of wire osteosynthesis in a university teaching hospital in Burkina Faso and discusses some of its other benefits and disadvantages. Notes of 227 patients with facial fractures treated by wire internal fixation at department of stomatology and maxillofacial surgery of CHU Souro Sanou, Burkina Faso between 2006 and 2010 are reviewed retrospectively. A satisfactory treatment outcome was recorded in 91.2% of the 227 patients. Complications occurred in 8.8% of the patients who had operative site infection (3.1%), malocclusion (1.8%), sensory disturbance (1.8), facial asymmetry (1.3%), delayed bone union (0.9%) or enophtalmos (0.4%). The overall complications rate was 7.4% after mandibular osteosynthesis, 6.9% after Le Fort osteosynthesis and 6.5% after zygoma osteosynthesis. Post operative infections occurred irrespective to the surgical site. The other complications were more specific to the surgical site. Wire internal fixation may be a reasonable alternative for the surgical treatment of non-comminuted facial fractures and those without bone substance loss, in the setting of limited resources.
Résumé -Introduction : L'objectif de cette étude était de contribuer à l'amélioration de la prise en charge des accidents d'évolution de la dent de sagesse inférieure au centre hospitalier universitaire Yalgado Ouédraogo. Patients et méthode : Il s'agit d'une étude de cohorte descriptive allant du 01/01/2010 au 31/12/2012. Résultats : Nous avons enregistré 110 cas d'accidents d'évolution de la dent de sagesse inférieure. La tranche d'âge de 20 à 30 ans était la plus touchée avec une prédominance féminine (57,7 %). Les élèves et les étudiants (52,7 %) étaient les plus représentés. La douleur, retrouvée dans 59,1 % des cas, a été le principal motif de consultation. Le type de malposition le plus fréquent était la dent de sagesse inférieure enclavée (81,3 %) en position mésio-angulaire (56,6 %), le plus souvent bilatérale. Les accidents infectieux et nerveux étaient le plus fréquemment rencontrés. Le traitement était l'avulsion des dents de sagesse sous anesthésie générale ou sous anesthésie locale. Conclusion : Un dépistage précoce suivi d'une germectomie permettrait de réduire la morbidité liée aux accidents d'évolution de la dent de sagesse inférieure.Abstract -Accidents due to the development of the bottom wisdom tooth in the odonto-stomatology and maxillofacial surgery department at yalgado ouedraogo teaching hospital.
