Improving triage accuracy through a modified nurse-administered emergency department assessment of chest pain score on patients with chest pain at triage (EDACT): A prospective observational study

BackgroundChest pain triage in our emergency department (ED) prioritize patients for consultation based on unstructured nursing gestalt. The Emergency Department Assessment of Chest Pain Score (EDACS) identifies patients at low-risk for major adverse cardiac events and may provide standardization for chest pain triage in ED.MethodsWe conducted a prospective observational study, including adult patients with chief complaint of chest pain who were self-conveyed. We aimed to evaluate the overall diagnostic performance of a modified EDACS in triaging these patients.ResultsData was collected over 6 weeks, with 284 patients included in the final analysis. Nursing gestalt had higher sensitivity (97.6%, 95% confidence interval [CI] 87.4% to 99.9% versus EDACS 45.2%, 95% CI 29.8% to 61.3%), while modified EDACS provided higher specificity (76.4%, 95% CI 70.6% to 81.6%, versus nursing gestalt 29.8%, 95% CI 24.1% to 35.9%). EDACS with electrocardiogram had significantly better area under the receiver operating characteristic curve statistic (0.712; 95% CI 0.631 to 0.793) than EDACS alone (0.608; 95% CI 0.528 to 0.689) and nursing gestalt (0.637; 95% CI 0.600 to 0.674) (p = 0.0324).ConclusionsFurther studies should explore if modified EDACS, together with nursing gestalt, can improve triage accuracy for ED patients with chest pain.     

Respuesta a antiangiogénicos en el edema macular secundario a necrosis retiniana aguda

A 55 year-old female patient with unilateral Acute Retinal Necrosis (ARN) developed macular oedema (MO) after the resolution of her necrosis. The macular oedema (MO) was managed and controlled for four years with intravitreal anti-VEGF injections. Anti-VEGF therapy could be useful for the treatment of MO secondary to ARN, the same as for treating MO resulting from panuveitis, where its efficacy has been already demonstrated.     

Vitrectomy with Silicone Oil Tamponade in Rhegmatogenous Retinal Detachment following Acute Retinal Necrosis: Clinical Outcomes and Prognostic Factors

Purpose: The purpose of the study is to report the prognostic factors and outcomes of vitrectomy (PPV) with silicone oil tamponade in rhegmatogenous retinal detachment (RRD) secondary to acute retinal necrosis (ARN).

Methods: This retrospective, non-randomized, interventional comparative study included 38 eyes of 38 patients. All cases underwent PPV with silicone oil tamponade. The main outcome measure was improvement of final visual acuity relative to the presenting visual acuity and factors affecting the same Group A included eyes with favorable vision of 20/400 or better and Group B included the others.

Results: Group A included 16 eyes (42.10%), group B included 22 eyes (57.89%). In Group A 2 eyes out of 16 (12.5%) and in Group B 12 eyes out of 22 (54.54%) had RRD at presentation (p = 0.02, 95% CI for the difference 7.88–65.78%). The time interval between first presentation and development of RRD in Group A was 30.94 ± 38.8 days (median 30 days) whereas that in Group B was 10.81 ± 11.73 days (median 8 days) (p = 0.02). The odds of visual improvement post-vitrectomy when RRD occurred later was 8.4 (p = 0.01, 95% CI 1.53–46.1). The usage of systemic steroids (odds 5.2, p = 0.03, 95% CI 1.14–23.54) and oral valacyclovir (odds 4.33, p = 0.04, 95% CI 1.05–17.84) were associated with odds favoring a good visual outcome. Recurrent RRD was noted in 3/16 eyes (18.75%) in Group A and 13/22 eyes (59.09%) in Group B (p = 0.03).

Conclusion: Delayed occurrence of RRD after ARN is a good prognostic factor. Usage of systemic steroids and oral valacylocvir are associated with a favorable visual outcome when started before the onset of RRD.     

Safety of Transesophageal Echocardiography to Guide Structural Cardiac Interventions

BackgroundDespite the widespread use of transesophageal echocardiography (TEE) to guide structural cardiac interventions, studies evaluating safety in this context are lacking.ObjectivesThis study sought to determine the incidence, types of complications, and factors associated with esophageal or gastric lesions following TEE manipulation during structural cardiac interventions.MethodsThis was a prospective study including 50 patients undergoing structural cardiac interventions in which TEE played a central role in guiding the procedure (mitral and tricuspid valve repair, left atrial appendage closure, and paravalvular leak closure). An esophagogastroduodenoscopy (EGD) was performed before and immediately after the procedure to look for new injuries that might have arisen during the course of the intervention. Patients were divided in 2 cohorts according to the type of injury: complex lesions (intramural hematoma, mucosal laceration) and minor lesions (petechiae, ecchymosis). The factors associated with an increased risk of complications were assessed.ResultsPost-procedural EGD showed a new injury in 86% (n = 43 of 50) of patients, with complex lesions accounting for 40% (n = 20 of 50) of cases. Patients with complex lesions presented more frequently with an abnormal baseline EGD (70% vs. 37%; p = 0.04) and had a higher incidence of post-procedural dysphagia or odynophagia (40% vs. 10%; p = 0.02). Independent factors associated with an increased risk of complex lesions were a longer procedural time under TEE manipulation (for each 10-min increment in imaging time, odds ratio: 1.27; 95% confidence interval: 1.01 to 1.59) and poor or suboptimal image quality (odds ratio: 4.93; 95% confidence interval: 1.10 to 22.02).ConclusionsMost patients undergoing structural cardiac interventions showed some form of injury associated with TEE, with longer procedural time and poor or suboptimal image quality determining an increased risk. Imaging experts performing this technique should be aware of the nature of potential complications, to take the necessary precautions to prevent their occurrence and facilitate early diagnosis and treatment.     

Genu varum and football participation: Does football participation affect lower extremity alignment in adolescents?

BackgroundGenu varum is one of the most common anatomical variations of knee alignment which is considered a risk factor for anterior knee pain and anterior cruciate ligament injury among football players. Considering that millions of children participate in high-level football training, the purpose of this study was to determine the genu varum development in adolescent football players and non-athlete peers. The hypothesis of this study was that genu varum incidence was higher in adolescent football players compared with non-athletic peers.MethodsThe design was a cross-sectional study. Two-hundred and thirty-seven male football players (FG) and aged-matched and anthropometrically similar non-athletes (CG) were recruited into the study. The quadriceps angle and intercondylar–intermalleolar distance were measured to evaluate the leg alignment. The distance between the medial edges of the condyles and malleoli was measured in millimeters using a digital caliper while angle measurements were performed using a photographic technique in a standing position. To analyze the variables, comparison, correlation and regression statistical tests were performed.ResultsThe intercondylar–intermalleolar distance and quadriceps angle values were significantly higher in FG than CG in all ages. In FG, a very strong correlation was found between number of training years and the intercondylar–intermalleolar distance. The prevalence of genu varum was markedly higher in FG than CG (~37% vs. 2%, respectively) based on intercondylar–intermalleolar distance.ConclusionThis study determined that the prevalence of genu varum and abnormal quadriceps angles in adolescent football players is significantly higher compared with their non-athletic peers.
