Comparative efficacies of amoxicillin, clindamycin, and moxifloxacin in prevention of bacteremia following dental extractions.

We evaluated the efficacies of oral prophylactic treatment with amoxicillin (AMX), clindamycin (CLI), and moxifloxacin (MXF) in the prevention of bacteremia following dental extractions (BDE). Two hundred twenty-one adults who required dental extractions under general anesthesia were randomly assigned to a control group, an AMX group, a CLI group, and an MXF group (the individuals in the drug treatment groups received 2 g, 600 mg, and 400 mg, respectively, 1 to 2 h before anesthesia induction). Venous blood samples were collected from each patient at the baseline and 30 s, 15 min, and 1 h after the dental extractions. The samples were inoculated into BACTEC Plus aerobic and anaerobic blood culture bottles and were processed in a BACTEC 9240 instrument. Subculture and the further identification of the isolated bacteria were performed by conventional microbiological techniques. The prevalences of BDE in the control group, AMX group, CLI group, and MXF group were 96, 46, 85, and 57%, respectively, at 30 s; 64, 11, 70, and 24%, respectively, at 15 min; and 20, 4, 22, and 7%, respectively, at 1 h. Streptococcus spp. were the most frequently identified bacteria in all groups (44 to 68%), with the lowest percentage being detected in the AMX group (44%). AMX and MXF prophylaxis showed high efficacies in reducing the prevalence and duration of BDE, but CLI prophylaxis was noneffective. As a consequence, MXF prophylaxis is a promising antibiotic alternative for the prevention of BDE when beta-lactams are not indicated.

"Scheduling delay" in oral cancer diagnosis: a new protagonist.

Diagnostic delays in oral cancer have been classified as "patient delay" and "delay by the clinicians". However, the influence of the accessibility (scheduling delay) to the health care system in oral cancer diagnosis has not been studied before. To assess scheduling delay, a descriptive, cross-sectional study was designed. This study was based upon role-play telephone conversations with two standardised patients (lingual ulceration-SP1 and patient seeking fixed prosthodontics-SP2). that followed a structured script. The variables considered in the study were days to go until the arranged appointment, professional degree of the contacted person and referral to other provider of care. The scheduling delay for SP1 reached a median value of 1 day, and for SP2 was 6 days. When the professional degree (receptionist vs GDP) of the person arranging the appointment for the patient with lingual ulceration was considered, the scheduling delay was significantly shorter when the appointment was fixed by the GDP (X approximately i-X approximately j=4.5; 95%CI=-7.48,-1.51). GDPs gave priority to the patients with lingual ulcerations over those demanding fixed bridgework (X approximately i-X approximately j=6.48; 95%CI=-9.46,-3.50). The GDPs showed a high level of awareness of the oral cancer, however, educational interventions seem to be necessary for dental surgery receptionists.

An update on infective endocarditis of dental origin.

OBJECTIVES: The aim of this study was to analyse the prevalence of dental treatment and oral infections related to the development of infective endocarditis (IE). METHODS: A retrospective study of 103 cases of IE diagnosed from 1997 to 1999 was conducted in Galicia, Spain. RESULTS: According to the Duke's endocarditis criteria (1994), 87 cases (84.5%) were considered definite IE. A presumed oral portal of entry was recorded in 12 patients (13.7%). Oral infections were held responsible in six cases while the remaining six had received dental treatment in the previous three months (three tooth extractions, one scaling, one cleaning, one fillings). In eight cases of IE (66.6%) typical oral pathogenic microflora was identified, with Streptococcus viridans being the most frequent. In four patients no previous cardiac disease was recorded. CONCLUSIONS: These results suggest that prevalence and characteristics of IE cases of dental origin did not change significantly in the last decades. The need for increased oral hygiene and improved dental care should be emphasized on preventing IE of dental origin. Continued education of physicians and dentists on the importance of the knowledge of current prophylactic protocols should also be considered.

[Guidelines for antibiotic prophylaxis of bacterial endocarditis in patients undergoing dental therapy].

The objective of the present work was to know the guidelines of antibiotic prophylaxis in bacterial endocarditis used in different spanish health centers. A general dental practitioner asked orally in 50 Cardiology and/or Internal Medicine departments throughout Spain which prophylaxis should be administered to a patient with a mitral valve prosthesis before a dental extraction. The results obtained showed that only 36 (72%) departments used the latest prophylactic guidelines recommended by the American Heart Association or the British Society for Antimicrobial Chemotherapy. Among penicillin allergic patients the antibiotic of choice was erythromycin (60%) followed by clindamycin (28%), although administered at very different dosages (11 and 3, respectively). Only in 44% of the surveyed departments did the guidelines for allergic and non allergic patients correspond to the recommended protocol by the same study group. The controversy generated regarding the prophylactic indications for bacterial endocarditis might partially account for the results obtained in this study.

Intra-alveolar granulocytic sarcoma developing after tooth extraction.

Granulocytic sarcoma (GS) is a malignant tumour composed of poorly differentiated myeloid cells forming in an extramedullary site. It is generally associated with acute leukaemia, particularly the myelocytic type. Its appearance in patients with chronic myeloid leukaemia is exceptional. GS can appear in multiple locations with the oral cavity being rarely involved. A mandibular GS detected in a patient with chronic myeloid leukaemia 10 days after a tooth extraction is reported. The pathogenesis (by metastatic cells or migration through the Haversian canals) of the tumour is discussed.

Bacterial endocarditis of oral etiology in an elderly population.

The aim of this study was to analyze the prevalence and characteristics of bacterial endocarditis (BE) of oral origin in a group of elderly people. A retrospective study of 115 BE clinical records was performed, focusing on the demographic and predisposing features, as well as on the analytical and clinical variables. Twenty-two of the 115 cases were excluded as they were detected in intravenous drug users. Of the remaining 93 cases, 54.8% were diagnosed in patients older than 60 years of age (group A) and 45.2% in patients younger than 60 years (group B). There were 16 cases (17.2%) of oral origin; 4 BE cases mainly associated with tooth extractions were found in group A and 12 BE (most of them related with odontogenic abscesses) in group B. Within group A, 1 patient (25%) had not an underlying cardiac condition versus 5 cases (41.6%) in group B. Even though the prevalence of BE of oral origin in patients older than 60 is low, the high frequency of cardiopathies, poor oral health and high number of dental procedures shown by the old population makes them a risk group for BE of oral origin.

Extraoral etiology of halitosis.

Halitosis is a frequent complaint which is estimated to be found in around 50 to 60% of the general population and that carries serious personal and social repercussions. Although the majority of cases are due to oral problems, it is considered that 10-13% of halitosis cases are of extraoral etiology. In these cases the responsibility of the general dental practitioner, who is frequently the first person to examine and treat these patients, is to refer the patient for evaluation to an otorhinolaryngologist in order to rule out the presence of chronic tonsillitis or chronic sinusitis. If the otorhinolaryngologist does not detect alterations concerning his specialty, the digestive system should be explored in order to detect gastric pathology, obstructions or inflammatory gastrointestinal processes, the liver to rule out hepatic insufficiency or cirrhosis, the endocrine system to exclude diagnoses of diabetes or trimethylaminuria, the airways to rule out bronchiectasis or pulmonary abscesses, and the kidney to eliminate possible renal insufficiency. Finally, in the absence of any systemic organic pathology, the possibility of halitosis of psychiatric etiology, which requires the patient's psychological profile to be checked by the corresponding specialist, should be considered.
