Severe odontogenic infections : epidemiological, microbiological and therapeutic factors
2010
Objectives: A retrospective study is made of the odontogenic infections treated in La Paz University Hospital (Madrid, Spain) during 2007 and 2008, with an epidemiological and microbiological analysis of a large group of patients.Study Design: A retrospective descriptive study was made, involving the consecutive inclusion of all patients with odontogenic infection requiring admission to our hospital in the period between January 2007 and December 2008. Results: A total of 151 patients were included, with a mean age of 40.3 years and a balanced gender distribution. The most frequently affected teeth were those located in the posterior mandibular segments, caries being the main underlying cau…
Portraying infective endocarditis
2019
Infective endocarditis is a growing problem with many shifts due to ever-increasing comorbid illnesses, invasive procedures, and increase in the elderly. We performed this multinational study to depict definite infective endocarditis. Adult patients with definite endocarditis hospitalized between January 1, 2015, and October 1, 2018, were included from 41 hospitals in 13 countries. We included microbiological features, types and severity of the disease, complications, but excluded therapeutic parameters. A total of 867 patients were included. A total of 631 (72.8%) patients had native valve endocarditis (NVE), 214 (24.7%) patients had prosthetic valve endocarditis (PVE), 21 (2.4%) patients …
Viridans streptococcal infective endocarditis associated with fixed orthodontic appliance managed surgically by mitral valve plasty
2018
Abstract Rationale: Streptococcus viridans, a heterogeneous group of alpha-hemolytic streptococci, is part of the normal flora of the mouth, usually responsible for dental caries (Streptococcus mutans, Streptococcus sanguinis), and pericoronitis, as well as for subacute infective endocarditis. They are responsible for 40-60% of the endocarditis cases occurring on the normal valves, especially in male patients and over 45 years of age. A change in the bacterial flora of the oral cavity is taking part after orthodontic fixed appliances are introduced into the oral cavity, change that is associated with an increased concentration of the acidogenic bacteria. Bacteraemia is the consequence of or…
