A mouth watering case of Mycoplasma salivarium native mitral valve endocarditis: 'case report'.

BACKGROUND: Mycoplasma salivarium is part of our commensal oral flora and readily resides in dental plaque. Although considered indolent, few case reports have documented its pathogenic potential in humans. To this day no case of Mycoplasma salivarium infectious endocarditis has ever been described. CASE PRESENTATION: Our report describes a challenging case of Mycoplasma salivarium endocarditis, with a patient presenting with oligoarticular joint swelling, and later on in the course of his disease developed signs of right-sided heart failure. The diagnosis was initially mistaken for septic gonarthritis and was later established on the basis of echocardiography and eubacterial PCR of joint fluid. CONCLUSION: This report describes a first documented case of Mycoplasma salivarium culture negative endocarditis that was successfully treated with targeted antimicrobial therapy. Specific antimicrobial therapy targeting Mycoplasma spp, lead to clinical improvement, with radiological regression of the lesion and the resolution of the serum inflammation biomarkers.

Predictive Value of HAS-BLED and HEMORR2HAGES Bleeding Risk Scores After Percutaneous Coronary Intervention.

BACKGROUND: Various scoring systems have been developed to assess the risk of bleeding in medical settings. HAS-BLED and HEMORR2HAGES risk scores are commonly used to estimate bleeding risk in patients receiving anticoagulation for atrial fibrillation, but data on their predictive value in patients undergoing percutaneous coronary intervention (PCI) are limited. METHODS: This study evaluated and compared the predictive abilities of the HAS-BLED and HEMORR2HAGES bleeding risk scores in all-comer patients undergoing PCI. The PARIS score, specifically designed for patients undergoing PCI, was used as a comparator. The scores were calculated at baseline and compared with the occurrence of events during a 2-year clinical follow-up period. Between 2015 and 2017, all consecutive patients undergoing PCI we re prospectively enrolled and divided into risk tertiles based on bleeding risk scores. The primary end points were hierarchical major bleeding events, defined by Bleeding Academic Research Consortium types 3 through 5, and patient-oriented composite end points according to Bleeding Academic Research Consortium classification, which were assessed during the 2-year follow-up period. RESULTS: A total of 1,080 patients completed the follow-up period. Two years after index, 189 patients (17.5%) had experienced any bleeding, with 48 events (4.4%) classified as Bleeding Academic Research Consortium types 3 to 5. All bleeding risk scores showed statistically significant predictive ability for bleeding events. The HEMORR2HAGES score (C statistic, 0.73) was more effective than the HAS-BLED score (C statistic, 0.66; P = .07) and the PARIS score (C statistic, 0.66; P = .06) in predicting risk of major bleeding. Patients in high-risk bleeding groups also experienced a higher incidence of patient-oriented composite end points. CONCLUSIONS: The HEMORR2HAGES, HAS-BLED, and PARIS risk scores exhibited good predictive abilities for bleeding events following PCI. Patients at high risk of bleeding also demonstrated increased ischemic risk and higher mortality during the 2-year follow-up period.

Ischemic and Bleeding Outcomes According to the Academic Research Consortium High Bleeding Risk Criteria in All Comers Treated by Percutaneous Coronary Interventions.

Background: The Academic Research Consortium have identified a set of major and minor risk factors in order to standardize the definition of a High Bleeding Risk (ACR-HBR). Aims: The aim of this study is to stratify the bleeding risk in patients included in the Cardio-Fribourg registry, according to the Academic Research Consortium for High Bleeding Risk (ACR-HBR) definition, and to report ischemic and hemorrhagic events at 2-year of clinical follow-up. Methods: Between 2015 and 2017, consecutive patients undergoing percutaneous coronary intervention were prospectively included in the Cardio-Fribourg registry. Patients were considered high (HBR) or low (LBR) bleeding risk depending on the ARC-HBR definition. Primary endpoints were hierarchical major bleeding events as defined by the Bleeding Academic Research Consortium (BARC) grade 3-5, and ARC patient-oriented major adverse cardiac events (POCE) at 2-year follow-up. Results: Follow-up was complete in 1,080 patients. There were 354 patients in the HBR group (32.7%) and 726 patients in the low-bleeding risk (LBR) group (67.2%). At 2-year follow-up, cumulative BARC 3-5 bleedings were higher in HBR (10.5%) compared to LBR patients (1.5%, p < 0.01) and the impact of HBR risk factors was incremental. At 2-year follow-up, POCE were more frequent in HBR (27.4%) compared to LBR group (18.2%, <0.01). Overall mortality was higher in HBR (14.0%) vs. LBR (2.9%, p < 0.01). Conclusions: ARC-HBR criteria appropriately identified a population at a higher risk of bleeding after percutaneous coronary intervention. An increased risk of bleeding is also associated with an increased risk of ischemic events at 2-year follow-up.

Bleeding Risk Profile in Patients on Oral Anticoagulation Undergoing Percutaneous Coronary Interventions: A Prospective 24 Months Cohort Study.

Background: The Academic Research Consortium has identified a set of major and minor risk factors in order to standardize the definition of a high bleeding risk (ACR-HBR). Oral anticoagulation is a major criterion frequently observed. Aims: The objective of this study is to quantify the risk of bleeding in patients on oral anticoagulation with at least one additional major ACR-HBR criteria in the Cardio-Fribourg Registry. Methods: Between 2015 and 2017, consecutive patients undergoing percutaneous coronary intervention were prospectively included in the Cardio-Fribourg registry. The study population included patients with ongoing long-term oral anticoagulation (OAC) and planned to receive triple antithrombotic therapy. Patients were divided in two groups: patients on OAC with at least one additional major ACR-HBR criteria vs. patients on OAC without additional major ACR-HBR criteria. The primary endpoint was any bleeding during the 24-month follow-up. Secondary bleeding endpoint was defined as Bleeding Academic Research Classification (BARC) ≥3. Results: Follow-up was completed in 142 patients at high bleeding risk on OAC, of which 33 (23%) had at least one additional major ACR-HBR criteria. The rate of the primary endpoint was 55% in patients on OAC with at least one additional ACR-HBR criteria compared with 14% in patients on OAC without additional ACR-HBR criteria (hazard ratio, 3.88; 95%CI, 1.85-8.14; p < 0.01). Patients with additional major ACR-HBR criteria also experienced significantly higher rates of BARC ≥ 3 bleedings (39% at 24 months). Conclusion: The presence of at least one additional ACR-HBR criterion identifies patients on OAC who are at very high risk of bleeding after percutaneous coronary intervention.

Pitfalls in the triage and evaluation of patients with suspected acute ethanol intoxication in an emergency department.

Acute ethanol intoxication (AEI) is frequent in emergency departments (EDs). These patients are at risk of mistriage, and to leave the ED without being seen. This study's objective was to describe the process and performance of triage and trajectory for patients with suspected AEI. Retrospective, observational study on adults admitted with a suspected AEI within 1 year at the ED of an urban teaching hospital. Data on the triage process, patients' characteristics, and their ED stay were extracted from electronic patient records. Predictors for leaving without being seen were identified using logistic regression analyzes. Of 60,488 ED patients within 1 year, 776 (1.3%) were triaged with suspected AEI. This population was young (mean age 38), primarily male (64%), and professionally inactive (56%). A large proportion were admitted on weekends (45%), at night (46%), and arrived by ambulance (85%). The recommendations of our triage scale were entirely respected in a minority of cases. In 22.7% of triage situations, a triage reason other than "alcohol abuse/intoxication" (such as suicidal ideation, head trauma or other substance abuse) should have been selected. Nearly, half of the patients (49%) left without being seen (LWBS). This risk was especially high amongst men (OR 1.56, 95% CI 1.12-2.19), younger patients (< 26 years of age; OR 1.97, 95% CI 1.16-3.35), night-time admissions (OR 1.97, 95% CI 1.16-3.35), and patients assigned a lower emergency level (OR 2.32, 95% CI 1.58-3.42). Despite a standardized triage protocol, patients admitted with suspected AEI are at risk of poor assessment, and of not receiving optimal care.

Profound hyponatraemia in the emergency department: seasonality and risk factors.

AIMS OF THE STUDY: Profound hyponatremia (<125 mmol/l) is frequent in the emergency department. Its incidence appears to increase during hot weather. Our objectives were to investigate seasonal variations in the incidence of profound hyponatraemia and identify its risk factors. METHODS: The incidence of profound hyponatremia among patients admitted to the emergency department of a university hospital was compared between summer and winter periods over two successive years. Risk factors for profound hyponatraemia were analysed in a case-control retrospective study. Each adult patient admitted during the study periods with a blood sodium level <125 mmol/l was matched with two patients who had normal blood sodium concentrations. RESULTS: Of 28 734 analysed patients, 264 cases of profound hyponatraemia (0.92%) were identified. The incidence of profound hyponatraemia was higher in summer than in winter (1.29% vs 0.54%; odds ratio [OR] 2.39, 95% confidence interval [CI] 1.83-3.12). In a multivariate analysis, age (OR 1.02, 95% CI 1.01-1.03), psychiatric disorders (OR 2.69, 95% CI 1.86-3.89), and use of thiazide diuretics (OR 7.79, 95% CI 4.73-12.85) or potassium-sparing diuretics (OR 4.69, 95% CI 2.31-9.52) were associated with increased risk. Mortality was higher in cases than in controls (11.7% vs 6.9%, OR 1.75, 95% CI 1.05-2.92). CONCLUSIONS: The incidence of profound hyponatraemia was higher during the summer than the winter and was associated with excess risk of overall mortality. The use of thiazide and potassium-sparing diuretics was associated with the highest risk of hyponatraemia.
