Endoscopic treatment of spondylodiscitis: systematic review.

BACKGROUND: Spondylodiscitis is a severe condition where standalone antibiotic therapy resolves most cases. In refractory infections, open surgery may aid with infection debulking. However, significant morbidity can occur. Nowadays, endoscopic approaches are emerging as an alternative. However, until now, only small-scale studies exist. Being so, we carried the first systematic review on spondylodiscitis endoscopic debridement indications, technique details, and outcomes. METHODS: Search for all English written original studies approaching the spondylodiscitis endoscopic treatment was performed using PubMed and EBSCO host. Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed, and a pre-specified protocol was registered at PROSPERO (CRD42020183657). RESULTS: Fourteen studies involving 342 participants were included for analysis. Data overall quality was fair. Indications for the endoscopic approach were poorly defined. The most consensual indication was refractory infection to conservative treatment. Spinal instability or neurological deficits were common exclusion criteria. All authors described similar techniques, and despite the frequent severe co-morbidities, procedure morbidity was low. Re-interventions were common. Microorganism identification varied from 54.2 to 90.4%. Treatment failure among studies ranged from 0 to 33%. Pain, functional status, and neurological deficits had satisfactory improvement after procedures. CONCLUSIONS: The endoscopic debridement of spondylodiscitis seems to be an effective and safe approach for refractory spondylodiscitis. A novel approach with initial endoscopic infection debulking and antibiotic therapy could improve the success of spondylodiscitis treatment.

COVID-19 vaccines-associated Takotsubo cardiomyopathy: A narrative review.

Takotsubo cardiomyopathy (TTC) is a severe, acute, reversible, and self-limited cardiac dysfunction. It usually affects postmenopausal women and is mostly triggered by physical or emotional stressors. Following the COVID-19 pandemic, millions of doses of different types of COVID-19 vaccines are being administered globally. There have been reports of different cardiac complications after receiving COVID-19 vaccines. To our knowledge, there have been 16 reported cases of COVID-19 vaccination-associated TTC. In this study, we first provide a brief overview of TTC and then an overview of selected reported TTC cases following COVID-19 vaccinations. It is crucial to highlight that the occurrence of TTC after vaccination does not establish a direct cause-and-effect relationship between immunization and TTC. Further investigations are necessary to examine any potential association between COVID-19 vaccines and the incidence of TTC. Additionally, the benefits of receiving COVID-19 vaccines significantly outweigh the potential risks of developing adverse events.

Role of the Electrocardiogram for Identifying the Development of Atrial Fibrillation.

Atrial fibrillation (AF), a prevalent cardiac arrhythmia, is associated with increased morbidity and mortality worldwide. Stroke, the leading cause of serious disability in the United States, is among the important complications of this arrhythmia. Recent studies have demonstrated that certain clinical variables can be useful in the prediction of AF development in the future. The electrocardiogram (ECG) is a simple and cost-effective technology that is widely available in various healthcare settings. An emerging body of evidence has suggested that ECG tracings preceding the development of AF can be useful in predicting this arrhythmia in the future. Various variables on ECG especially different P wave parameters have been investigated in the prediction of new-onset AF and found to be useful. Several risk models were also introduced using these variables along with the patient's clinical data. However, current guidelines do not provide a clear consensus regarding implementing these prediction models in clinical practice for identifying patients at risk of AF. Also, the role of intensive screening via ECG or implantable devices based on this scoring system is unclear. The purpose of this review is to summarize AF and various related terminologies and explain the pathophysiology and electrocardiographic features of this tachyarrhythmia. We also discuss the predictive electrocardiographic features of AF, review some of the existing risk models and scoring system, and shed light on the role of monitoring device for screening purposes.

Unveiling a Critical Subacute Complication: Right Apical Septum Pacemaker Lead Dislodgement Leading to Right Ventricular Perforation and Minimal Pericardial Effusion.

The implantation of cardiac pacing devices, such as pacemakers and implanted cardioverter-defibrillators (ICDs), has significantly improved patient outcomes in the treatment of a range of cardiac arrhythmias. Right ventricular (RV) pacing lead perforation is an uncommon but potentially dangerous complication that can occur despite technical breakthroughs. RV lead perforation, which can result in right ventricular perforation as well as possible pulmonary or vascular harm, is caused by the pacing lead breaking through the myocardial wall. Despite being rare, this complication warrants attention because of the risks for morbidity and mortality that are involved. We present a case of right ventricular perforation caused by a pacemaker lead and examine the nuances of RV lead perforation in this instance, including its prevalence, clinical presentation, diagnostic difficulties, and treatment strategies, illuminating the many factors to be taken into account while properly managing this issue.

A Rare Occurrence of Spontaneous Coronary Artery Dissection in Elderly: Diagnostic Challenges and Clinical Implications.

Spontaneous coronary artery dissection (SCAD) is the ripping of the epicardial coronary artery wall without any trauma, coronary procedures, or rupture of atherosclerotic plaque. Intimal rip, intramural hematoma, and false lumen formation are the hallmarks of this disease, which may result in coronary blood flow obstruction and myocardial ischemia. The role of SCAD in acute coronary syndrome (ACS), and sudden death has come to light more and more, particularly in young females and those with few typical atherosclerotic risk factors. This study details a 65-year-old female with a history of hypertension, hyperlipidemia, asthma, and chronic kidney disease who presented with severe chest pain and elevated troponin levels. Upon investigation, spontaneous dissection of the left anterior descending artery (LAD) involving its mid and distal segments was identified. The present case highlights a rare occurrence of spontaneous coronary artery dissection (SCAD) in a demographic typically unaffected by the condition - females aged 65 years and over. The atypical presentation underscores the importance of reporting such cases to prevent oversight. This patient's case is particularly noteworthy as it deviates from the typical predisposing factors associated with SCAD, such as youth, pregnancy, or stressors. Additionally, the case is unique in that it presented both SCAD and imaging findings consistent with takotsubo cardiomyopathy, suggesting a complex cardiac pathology deserving of further study and consideration.

Black Cohosh: An Uncommon Culprit of Bradycardia in Postmenopausal Women.

The use of herbal supplements has become increasingly prevalent, with black cohosh (BC) gaining popularity for managing menopausal symptoms. However, reports of adverse effects associated with BC are limited. We present a case of bradycardia linked to prolonged BC ingestion. A 76-year-old postmenopausal woman who has been taking BC for years has had syncopal attacks multiple times during the past years associated with bradycardia with the heart rate dropping to 30 beats/minute with no identifiable cause. Discontinuation of BC resulted in a gradual resolution of bradycardia, highlighting a plausible association. There were no additional pharmacological or invasive interventions required.

Association of Paroxysmal Versus Persistent Atrial Fibrillation with In-hospital Outcomes and 30-day Readmission After Inpatient Atrial Fibrillation Ablation.

Knowledge of the impact of paroxysmal and persistent atrial fibrillation (AF) after catheter ablation on in-hospital outcomes and 30-day readmission remains limited. This study aimed to evaluate the procedural outcomes and 30-day readmission rates among patients with paroxysmal or persistent AF who were hospitalized for AF ablation. Using the Nationwide Readmissions Database, our study included patients aged ≥18 years with AF who were hospitalized and underwent catheter ablation during 2017-2020. Then, we compared the in-hospital procedural outcomes and 30-day readmission rates between patients with paroxysmal and persistent AF, respectively. Our study included 7310 index admissions for paroxysmal AF ablation and 9179 index admissions for persistent AF ablation. According to our analysis, there was no significant difference in procedural complications-namely, cerebrovascular accident, vascular complications, major bleeding requiring blood transfusion, phrenic nerve palsy, pericardial complications, and systemic embolization-between the persistent and paroxysmal AF groups. There was also no significant difference in early mortality between these groups (0.5% vs. 0.7%; P = .22). Persistent AF patients had significantly higher rates of prolonged index hospitalization (9.9% vs. 7.2%; P < .01) and non-home discharge (4.8% vs. 3.1%; P < .01). The 30-day readmission rates were comparable in both groups (10.0% vs. 9.5%; P = .34), with recurrent AF and heart failure being two of the most common causes of cardiac-related readmissions. Catheter ablation among hospitalized patients with paroxysmal or persistent AF resulted in no significant difference in procedural complications, early mortality, or 30-day readmission. This suggests that catheter ablation of AF can be performed with a relatively similar safety profile for both paroxysmal and persistent AF.

Impact of Sarcoidosis on In-hospital Outcomes Among Patients with Atrial Fibrillation: A Nationwide Readmissions Database Analysis.

Sarcoidosis is a disease that involves multiple organs, including the cardiovascular system. While cardiac sarcoidosis has been increasingly recognized, the impact of sarcoidosis on atrial fibrillation (AF) is not well established. This study aimed to analyze the impact of sarcoidosis on in-hospital outcomes among patients who were admitted for a primary diagnosis of AF. Using the all-payer, nationally representative Nationwide Readmissions Database, our study included patients aged ≥18 years who were admitted for AF between 2017-2020. We stratified the cohort into two groups depending on the presence of sarcoidosis diagnosis. The in-hospital outcomes were assessed between the two groups via propensity score analysis. A total of 1031 (0.27%) AF patients with sarcoidosis and 387,380 (99.73%) AF patients without sarcoidosis were identified in our analysis. Our propensity score analysis of 1031 (50%) patients with AF and sarcoidosis and 1031 (50%) patients with AF but without sarcoidosis revealed comparable outcomes in early mortality (1.55% vs. 1.55%, P = 1.000), prolonged hospital stay (9.51% vs. 9.70%, P = .874), non-home discharge (7.95% vs. 9.89%, P = .108), and 30-day readmission (13.29% vs. 13.69%, P = .797) between the two groups. The cumulative cost of hospitalization was also similar in both groups ($12,632.25 vs. $12,532.63, P = .839). The in-hospital adverse event rates were comparable in both groups. Sarcoidosis is not a risk factor for poorer in-hospital outcomes following AF admission. These findings provide valuable insights into the effectiveness of the current guideline for AF management in patients with concomitant sarcoidosis and AF.

Amniocentesis in HIV pregnant women: 16 years of experience.

The iatrogenic risk of HIV vertical transmission, calculated in initial epidemiologic studies, seemed to counterindicate invasive prenatal diagnosis (PND) procedures. The implementation of highly active antiretroviral therapy (HAART) represented a turning point in PND management, owing to a rapid and effective reduction of maternal viral load (VL). In the present study, we identified cases of vertical transmission in HIV-infected pregnant women who did amniocentesis in the second trimester of pregnancy (n = 27), from 1996 to 2011. We divided our sample into Group A--women under HAART when submitted to amniocentesis (n = 20) and Group B--women without antiretroviral therapy before amniocentesis (n = 7). We had 1 case of vertical transmission in Group B. Preconceptional or early first trimester HIV serology is essential to avoid performing an amniocentesis without antiretroviral therapy or viral suppression. When there is an indication for amniocentesis in an HIV-infected pregnant woman, it should be done if the patient is on HAART and, if possible, when VL is undetectable. Nowadays, with combined first trimester screening test to select pregnancies with high risk of aneuploidies, advanced maternal age is a less frequent indication to perform PND invasive procedures, representing an outstanding gain in prenatal diagnosis of this population.

Massive Atrial Thrombosis: A Serious Complication of the Maze Procedure Triggered by Heparin-Induced Thrombocytopenia (HIT).

Atrial fibrillation is one of the most common cardiac arrhythmias, classically presenting with an "irregularly irregular" rhythm with or without chest pain, palpitations, shortness of breath, lightheadedness, or fatigue. The maze procedure is an open-heart operation that creates a carefully designed maze of incisions and ablations in the atrial myocardium. Although it is a common procedure, serious complications may happen. Herein, we report on a 76-year-old man who presented with chest pain and atrial fibrillation and was found to have multi-vessel disease on a coronary angiogram. He underwent coronary artery bypass and the COX-maze procedure, which was complicated by a massive thrombosis in the atria and the superior vena cava following the ablation line, secondary to heparin-induced thrombocytopenia, which is extremely rare. The central focus of this paper is to present this rare complication to stress the importance of rigorous follow-up and anticoagulation therapy in patients undergoing the maze procedure. To our knowledge, we are the first to report such a rare case of diffuse large atrial thrombi triggered by heparin-induced thrombocytopenia (HIT) type II after a COX-maze procedure.
