Clostridial deep neck infection developed after extraction of a tooth: a case report and review of the literature in Japan

The necessity of administrating antibiotic prophylaxis to patients with diabetes mellitus prior to oral surgical procedures-a systematic review

BACKGROUND AND AIMS

Μany studies suggest the use of antibiotic prophylaxis (AP) as an appropriate preventive measure for patients with diabetes mellitus (DM) due to the increased possibility of an impaired wound healing and infections after surgical procedures in the oral cavity. Existing recommendations regarding antibiotic prophylaxis before surgical procedures are not definitive and are based on expert opinions. The purpose of this study was to review the available scientific data about the necessity of administrating AP as a preventive measure prior to oral surgical procedures.

METHOD

PubMed®, Scopus® και Cochrane Central Register of Controlled Trials (CENTRAL) were used as databases to search for published research. All articles were initially identified and classified based on the title and subsequently on their abstract. For the next level the full scientific paper was read and evaluated.

RESULTS

Overall, 22 articles were included in the study, of which 2 were systematic reviews, 2 cohort studies, 2 case-control studies, 1 case series, 8 case reports and 7 professional association publications.

CONCLUSIONS

In the scientific literature, there is a wide range of recommendations and inconsistency regarding the need to administer AP prior to surgical dental operations in patients with DM, while there is no scientific evidence demonstrating its' effectiveness as a precautionary measure. Both blood glucose level measurements and recent HbA1c measurement should be evaluated before any dental procedure. Poor regulation may result to life-threatening infections after tooth extraction. AP is recommended prior to the placement of dental implant. Randomized, controlled, clinical trials with large number of participants and greater variety of surgical dental procedures are needed.

Streptococcus oralis Meningitis with Gingival Bleeding in a Patient: A Case Report and Review of the Literature

An 81-year-old man with a history of gingival bleeding presented with a fever, headache, and drowsiness. His mouth and full dentures were unsanitary. Laboratory tests revealed Streptococcus oralis meningitis caused by odontogenic bacteremia. We reviewed eight reported cases, including the present case, because S. oralis meningitis is rare. Our review indicated that S. oralis meningitis needs to be considered when encountering cases of a fever, disturbance of consciousness, and headache with episodes of possible odontogenic bacteremia.

Infections and infestations

●

Increasing population mobility means that a wide range of infections is seen globally

●

Infections are especially common in immunodeficient people

Is there association between severe multispace infections of the oral maxillofacial region and diabetes mellitus?

PURPOSE

This study aims to identify the impact of diabetes on the final outcome (length of hospital stay and development of complications) in patients with severe multispace infections in the head and neck. Furthermore, it intends to characterize significant clinical features of these patients compared with nondiabetics.

MATERIALS AND METHODS

A retrospective study was conducted in 117 patients who received treatment for multispace infections of the head and neck region from 2007 through 2010 at the Department of Oral and Maxillofacial Surgery, Shanghai Ninth Hospital. The study identified diabetic patients and compared them with nondiabetic patients. Demographics, etiology of infection, clinical parameters (time from first onset of symptoms to hospital admission, number of spaces affected, and distribution of involved spaces), and laboratory values (bacteriology, admission blood glucose level, admission white blood cell count, and percentage of neutrophils on admission) were analyzed for clinical significance. Statistical analyses of the results between groups were performed using the Student t test, χ(2) test, variance analysis, logistic regression analysis, and linear regression analysis.

RESULTS

Admission blood glucose level was the only factor influencing the complications in multispace infections in the oral-maxillofacial region. Compared with nondiabetic patients, diabetics had infections that involved more spaces, longer hospital stays, and more frequent complications. Some diabetic patients died. The disease status (with or without diabetes) was associated with clinical outcomes (length of hospital stay and complications) in the therapy procedures.

CONCLUSIONS

This study identifies uncontrolled diabetes mellitus as an important indicator of clinical features and outcomes in treating multispace infections of the oral-maxillofacial region.
