[Contribution of CT scan and radio-histological concordance in the diagnosis of maxillomandibular tumors at the Dental University Hospital of BAMAKO]. / Apport de la tomodensitometrie et concordance radio-histologique dans le diagnostic des tumeurs maxillo-mandibulaires au Centre Hospitalier Universitaire-Centre National D'Odonto-Stomatologie (CHU-CNOS) de BAMAKO.

INTRODUCTION: The aim of this study was to investigate the contribution of computed tomography (CT) and its degree of concordance with pathological examination in the etiological diagnosis of maxillomandibulartumours. MATERIALS AND METHODS: Our study was cross-sectional, retrospective and prospective. It took place over a period of five years and six months and included cases of maxilla-mandibulartumours confirmed by pathological examination after clinical examination and CT scan. Data were collected from medical records, entered and analysed with SPSS 21.0 software. RESULTS: Men represented 55.7% of cases with a sex ratio of 1.25. The duration of symptoms on presentation varied from 1 month to 27 years (mean 24.37+/- 48 months). This consultation was motivated in 92.6% of cases by a mandibular swelling. Squamous cell carcinomas were the most common on pathological examination with 34.2% of cases followed by ameloblastomas in 24.2% of cases. There was good agreement between the results of the CT scan and those of the pathological examination (Cohen's Kappa=0.77). CONCLUSION: CT remains a reliable tool in the diagnosis of maxillomandibulartumours.

High prevalence of dental caries among HIV-infected children in West Africa compared to uninfected siblings.

INTRODUCTION: The objectives of this study were to investigate the association between HIV infection and dental caries among children in West Africa, and to identify factors associated with dental caries among HIV-infected children. METHODS: We conducted a multi-center cross-sectional study in Mali, Senegal and Côte d'Ivoire with a random sample of HIV-infected children aged 5-15 years on antiretroviral therapy and their uninfected siblings. A standardized examination was performed by calibrated dentists. The association between the number of decayed, missing or filled permanent and primary teeth surfaces (DMFdefS) and HIV status was investigated by fitting multivariable zero-inflated negative binomial models, for each age group (<12 and ≥12 years). Factors associated with dental caries could be investigated only for HIV-infected children <12 years old. RESULTS: The sample included 420 HIV-infected children and 418 non-infected siblings. The median DMFdefS was 7 for the HIV-infected children and 2 for the uninfected siblings. The proportion of children with DMFdefS ≥1 was significantly higher among the HIV-infected children than uninfected children (86.0 percent versus 64.4 percent, P < 0.001). The HIV-infected children were less likely to be caries-free than the uninfected siblings in both age groups. We found a higher degree of caries experience among HIV-infected children < 12 years old, in whom it was associated with sweet drink consumption, history of night bottle use, immunosuppression, and younger age at study entry. CONCLUSIONS: Although preventable, the burden of dental disease was high in children from families affected by HIV in West Africa and was associated with HIV infection and immunosuppression.

[Mediastinitis complicating cervical cellulite: 8 cases observed in the ear, nose and throat department of the Gabriel Toure university hospital, Bamako (Mali)]. / Mediastinite compliquant une cellulite cervicale : a propos de 8 cas observes dans le service orl du chu Gabriel Toure de Bamako (Mali).

OBJECTIVE: The objective of this work was to analyze the diagnostic circumstances and the therapeutic management of mediastinal disease of a cervical origin. PATIENTS AND METHODS: We conducted a longitudinal prospective and retrospective descriptive study in the ENT department of the Gabriel Touré Hospital in Bamako, involving the records of patients treated for mediastinitis complicating cervical cellulite from January 2011 to April 2014. RESULTS: Eight patients met our inclusion criteria. The median age was 29 years, the standard deviation was 10.23 years with extremes of 25 and 57 years. All were initially admitted for dental reasons. The median time to consultation was 13 days with extremes of 10 days and 1 month. Six patients had non-steroidal anti-inflammatory drugs before entry into the service. Cervical and thoracic CT scan was used to guide diagnosis in all cases. Seven patients underwent mediastinal drainage through cervicotomy, 3 patients underwent percutaneous pleural drainage under ultrasound guidance. We had two deaths. CONCLUSION: Mediastinitis in cervical cellulitis is a serious infectious disease where the mortality rate remains high. Mediastinal drainage was performed by cervical route. Prevention is based on the awareness and the importance of dental hygiene and getting proper and early treatment for dental cavities.

OBJECTIF: L'objectif de ce travail était d'analyser les circonstances de diagnostic et la prise en charge thérapeutique des affections médiastinales à point de départ cervical. PATIENTS ET MÉTHODES: Nous avons mené une étude descriptive longitudinale pro et rétrospective dans le service d'ORL du CHU Gabriel Touré de Bamako et qui a concerné les dossiers des patients traités pour médiastinite compliquant une cellulite cervico-faciale de janvier 2011 à Avril 2014. RÉSULTATS: Huit patients ont répondu à nos critères d'inclusion. L'âge médian était de 29 ans, l'écart type était de 10,23 ans avec des extrêmes de 25 et 57 ans. La porte d'entrée a été dentaire dans tous les cas. Le délai médian de consultation était de 13 jours avec des extrêmes de 10 et 1 mois. Six patients avaient eu des antiinflammatoires non stéroïdiens avant leur admission dans le service. Le scanner a permis d'orienter diagnostic, en montrant des signes en faveur de médiastinite, dans tous les cas. Sept patients ont bénéficié d'un drainage du médiastin par voie de cervicotomie, 3 patients ont bénéficié d'un drainage pleural percutané sous guidage échographique. Nous avons eu deux décès. CONCLUSION: La médiastinite au cours de la cellulite cervicale représente une pathologie infectieuse grave avec une mortalité qui reste élevée. Le drainage médiastinal a été effectué par voie cervicale. La prévention repose sur la sensibilisation de la population et sur l'importance de l'hygiène dentaire et la prise en charge correcte et précoce des caries dentaires.

Oral lesions among HIV-infected children on antiretroviral treatment in West Africa.

OBJECTIVE: To estimate the prevalence of oral mucosal diseases and dental caries among HIV-infected children receiving antiretroviral treatment (ART) in West Africa and to identify the factors associated with the prevalence of oral mucosal lesions. METHODS: Multicentre cross-sectional survey in five paediatric HIV clinics in Côte d'Ivoire, Mali and Sénégal. A standardised examination was performed by trained dentists on a random sample of HIV-infected children aged 5-15 years receiving ART. The prevalence of oral and dental lesions and mean number of decayed, missing/extracted and filled teeth (DMFdefT) in temporary and permanent dentition were estimated with their 95% confidence interval (95% CI). We used logistic regression to explore the association between children's characteristics and the prevalence of oral mucosal lesions, expressed as prevalence odds ratio (POR). RESULTS: The median age of the 420 children (47% females) enrolled was 10.4 years [interquartile range (IQR) = 8.3-12.6]. The median duration on ART was 4.6 years (IQR = 2.6-6.2); 84 (20.0%) had CD4 count<350 cells/mm(3). A total of 35 children (8.3%; 95% CI: 6.1-11.1) exhibited 42 oral mucosal lesions (24 were candidiasis); 86.0% (95% CI = 82.6-89.3) of children had DMFdefT ≥ 1. The presence of oral mucosal lesions was independently associated with CD4 count < 350 cells/mm(3) (POR = 2.96, 95% CI = 1.06-4.36) and poor oral hygiene (POR = 2.69, 95% CI = 1.07-6.76). CONCLUSIONS: Oral mucosal lesions still occur in HIV-infected African children despite ART, but rarely. However, dental caries were common and severe in this population, reflecting the need to include oral health in the comprehensive care of HIV.
