BACKGROUND The bacterial flora involved in brain abscess is often complex. In a previous study, using a metagenomic approach based on 16S ribosomal DNA (rDNA) amplification, we demonstrated that the diversity of the microbial flora involved in these infections was underestimated. METHODS We performed a 16S rDNA-based metagenomic analysis of cerebral abscesses from patients diagnosed from 2006...

OBIECTIVE AND IMPORTANCE: We pr€sent a case report of a patient wilh a left frontal brain abccess. Cultures obtained fiom the abecess at lhe time of suqgery were idenlified as dental flora knovm to establish a synergistic relationslrip in polymicrobial infections. Ihis type of synergistic relalionship nukes the clearance of an infeclion more difficult for an intact immune sydem. A serum immunog...

Background/Aim. The most common cause of acute dental infections are oral streptococci and anaerobe bacteria. Acute dentoalveolar infections are usually treated surgically in combination with antibiotics. Empirical therapy in such infections usually requires the use of penicillin-based antibiotics. The aim of this study was to investigate the clinical efficiency of amoxicillin and cefalexin in ...

parapharyngeal abscess is a life-threatening disease. upper respiratory tract infection is the main cause in children. we present a 15-month-old boy admitted to the emergency ward with the chief complaint of difficulty in breathing caused by parapharyngealabscess. his condition deteriorated gradually, and he transferred to the operation theater quickly for abscess drainage and because of the di...

Balo's concentric multiple scleroses (MS) is a rare demyelinating disease and a variant of multiple sclerosis. We report a case with interesting misleading clinical history and typical RI findings of Balo disease. A 19-year-old girl presented with fever and left hemiparesis following dental procedure 15 days ago. On physical examination fever and left limbs forces loss were noted. On CT scan a ...

A 40-year-old female presented to the emergency department with a one-week history of URI symptoms and a one-day history of more severe throat pain and swelling. Upon physical examination the patient was afebrile and although she did not demonstrate any signs of respiratory distress, examination of her neck revealed fullness on the right. A lateral plain film of the neck showed soft tissue swel...

BACKGROUND Brain abscesses and ischaemic strokes complicate pulmonary arteriovenous malformations (PAVMs). At risk individuals are poorly recognised. Stroke/abscess risk factors have not been defined. METHODS A cohort study of 323 consecutive individuals with PAVMs (n = 219) and/or the commonly associated condition hereditary haemorrhagic telangiectasia (HHT, n = 305) was performed. Most of t...

Family physicians commonly encounter patients with dental infections, such as dental caries and periodontal disease. Dental caries is caused by bacteria that destroy the enamel and dentin; it can be detected by an oral examination that shows stained pits or fissures on the tooth surface. Use of fluoride is the most effective prevention measure for dental caries. Untreated caries may progress to...
