Prevalencia de endocarditis infecciosa a partir de procedimientos odontológicos / Prevalence of infective endocarditis from dental procedures

Resumen Introducción: Los procedimientos dentales han sido asociados a bacteriemia y endocarditis infecciosa. Objetivo: Determinar la prevalencia de endocarditis infecciosa a partir de procedimientos odontológicos. Materiales y métodos: Se realizó un estudio descriptivo de tipo retrospectivo cuantitativo. Se incluyeron historias clínicas de pacientes con endocarditis infecciosa a los cuales se les registró identificación general, sexo, edad, estrato socioeconómico, reporte de procedimiento odontológico, tipo de procedimiento odontológico, endocarditis infecciosa no especificada y reporte de procedimiento médico-quirúrgico. Adicionalmente, se registró información sobre el tipo de procedimiento médico-quirúrgico o condición médica relacionada. Los datos fueron compilados en hoja de cálculo para su procesamiento en software estadístico (SPSS ver. 25). Resultados: De 154 casos de endocarditis infecciosa registrados, solo en uno (0.7%) se reportó procedimiento odontológico del tipo endodoncia previo a la hospitalización. La causa relacionada más comúnmente reportada fue cateterismo para hemodiálisis (37%) seguido de bacteriemia no específica (22%) y condición cardiovascular asociada a válvulas cardíacas y marcapasos (18.8%). En el 15.6% de los casos se reportó como endocarditis infecciosa no especificada. Los microorganismos más comúnmente aislados pertenecen al género Staphylococcus, seguido de Streptococcus. Conclusiones: La frecuencia de endocarditis bacteriana relacionada con procedimientos odontológicos fue menor del 1%. Los procedimientos médico-quirúrgicos siguen siendo la causa más común de endocarditis bacteriana.

Abstract Introduction: Dental procedures have been associated with bacteriemia and infective endocarditis. Objective: To determine the prevalence of infective endocarditis from dental procedures. Materials and methods: A descriptive, retrospective quantitative study was carried out. Records of infective endocarditis of which the general identification, sex, age, socioeconomic status, dental procedure report, type of dental procedure and non-specified infective endocarditis information was collected. Additionally, information was recorded on the type of medical/surgical procedure or medical condition that was associated. Categorical variables are presented as absolute and relative frequencies. The data were compiled in a spreadsheet for processing in statistical software (SPSS ver. 25). Results: Of the 154 cases of infective endocarditis registered, only 1 case (0.7%) reported an endodontic-type dental procedure prior to hospitalization. The most reported related cause was catheterization for hemodialysis (37%) followed by unspecified bacteriemia (22%) and cardiovascular condition associated with heart valves and pacemakers (18.8%). In 15.6% of the cases, it was reported as non-specific infective endocarditis. The most isolated microorganisms belonged to the genus Staphylococcus followed by Streptococcus. Conclusions: The frequency of bacterial endocarditis related to dental procedures was less than 1%. Medical-surgical procedures remain the most common cause of bacterial endocarditis.

Antibiotic Prophylaxis Before Invasive Dental Procedures for Patients atHigh Risk of Infective Endocarditis - A Systematic Review

Background: Clinical use of antibiotics prophylaxis (AP) for preventing infective endocarditis (IE) after invasive dental procedures is controversial. Expert consensus guidelines are inconsistent, either restricting its use to high?risk individuals or advising its use again. Objectives: To determine whether there is a genuine need for AP to prevent IE in high?risk patients undergoing invasive dental procedures. Methods: Online search was performed on PubMed, Science Direct, British Dental Journal and Cochrane Register of Controlled Trials. The methodological quality of each study was assessed using the Cochrane Handbook for Systematic Reviews of Interventions. Results: Seventeen (17) clinical trials were included in the final analysis recruiting 2,410 patients (AP = 1,366; placebo = 1,044). Bacteraemia was detected in 302 AP patients (22.1%) and 362 placebo patients (34.7%). AP reduced the risk of bacteraemia by 49% (risk ratio: 0.51; 95% CI; 0.45 to 0.58; P = 0.0001). Conclusion: Although using AP for IE may be pragmatic and justified for high?risk patients undergoing invasive dental procedures, the evidence is inconclusive because post?procedural bacteraemia may not be a good surrogate marker for IE. Moreover, trials investigating the direct association between AP and IE are lacking due to low disease prevalence and high?cost challenges

Evaluation of patients' compliance to recall visits after tooth extraction at the Dental Centre, University of Benin Teaching Hospital (UBTH): A two-year retrospective study

ABSTRACT Objective: This study aims to evaluate the level of patients' compliance with recall / follow-up visits attending the dental Centre of the University of Benin Teaching Hospital (UBTH).Methods: This study adopted a descriptive retrospective study of case notes retrieved from the medical records department of the dental Centre, University of Benin Teaching Hospital. The period under study covers 2019 to 2021. The data was collected by means of 1232 questionnaire and analyzed using descriptive statistics such as frequency and percentages. Results: The result showed that the participants in the age bracket of 18-40 years of age (277) complied better to recall visit in comparison with the study age distributions which are 41-65 years (218) and age above 65 years (188). As per the influence of gender on compliance of patients with post-extraction recall visits, it was observed that the male participants (288) responded better to the recall visits compared to the female participants (251). The Relationship between distance away from the hospital and compliance of patients with post-extraction recall visits was also evaluated, and it was observed that the patients closer to the hospital within 5km (442) complied better to recall revisit in comparison to the participants who were within 10km (224) from the hospital as well as the participants that were 10km & above (17). Finally, the influence of interval between procedure and recall visit was also evaluated, and the result revealed that the participants that were given 7 days of recall revisit (663) complied better compared with the participants who were given 14days duration for recall revisit (478). Conclusion: The data from this study highlighted the possible need for a paradigm shift in patient-doctor interphase especially as it concerns recall visits. Compliance to recall appointment by the patients depends largely on age, gender, distance from hospital and interval between procedures and is mainly responsible for the noncompliance of patients to recall visit

Safety and Cost-Effectiveness of Bridge Therapies for Invasive Dental Procedures in Patients with Mechanical Heart Valves

PURPOSE: Bridge anticoagulation therapy is mostly utilized in patients with mechanical heart valves (MHV) receiving warfarin therapy during invasive dental procedures because of the risk of excessive bleeding related to highly vascular supporting dental structures. Bridge therapy using low molecular weight heparin may be an attractive option for invasive dental procedures; however, its safety and cost-effectiveness compared with unfractionated heparin (UFH) is uncertain. MATERIALS AND METHODS: This study investigated the safety and cost-effectiveness of enoxaparin in comparison to UFH for bridge therapy in 165 consecutive patients (57+/-11 years, 35% men) with MHV who underwent invasive dental procedures. RESULTS: This study included 75 patients treated with UFH-based bridge therapy (45%) and 90 patients treated with enoxaparin-based bridge therapy (55%). The bleeding risk of dental procedures and the incidence of clinical adverse outcomes were not significantly different between the UFH group and the enoxaparin group. However, total medical costs were significantly lower in the enoxaparin group than in the UFH group (p or =65 years) was significantly associated with an increased risk of total bleeding independent of bridging methods (odds ratio, 2.51; 95% confidence interval, 1.15-5.48; p=0.022). Enoxaparin-based bridge therapy (beta=-0.694, p<0.001) and major bleeding (beta=0.296, p=0.045) were significantly associated with the medical costs within 30 days after dental procedures. CONCLUSION: Considering the benefit of enoxaparin in cost-effectiveness, enoxaparin may be more efficient than UFH for bridge therapy in patients with MHV who required invasive dental procedures.

Anesthetic Management of a Patient with Glanzmann's Thrombasthenia: A case report / 대한마취과학회지

Glanzmann's thrombasthenia is a rare autosomal recessive disorder characterized by bleeding tendency due to decreased coagulation function of platelets. Perioperative adequate blood transfusion including preoperative platelet transfusion seems to be the most important component affecting anesthetic management. Also, minimally invasive techniques should be used at the time of induction of anesthesia and the use of recombinant activated coagulation factor VII may be considered. We successfully conducted an anesthetic management for dental procedure in a four-year-old child with Glanzmann's thrombasthenia using preoperative platelet transfusion. Thus we present this anesthetic experience and share informations on anesthetic management of patients with Glanzmann's thrombasthenia.
