BACKGROUND: Coronary artery disease (CAD) accounts for more than half of all cardiovascular events. Stress testing remains the cornerstone for non-invasive assessment of patients with possible or known CAD. Clinical utilization reviews show that most patients presenting for evaluation of stable CAD by stress testing are categorized as low risk prior to the test. Attempts to enhance risk stratification of individuals who are sent for stress testing seem to be more in need today. The present study compares artificial neural networks (ANN)-based prediction models to the other risk models being used in practice (the Diamond-Forrester and the Morise models)...

Inflammation plays a major role in colon carcinogenesis. Endogenously produced specialized proresolving lipid mediators (SPMs) play a central role in inflammation and tissue homeostasis, and have been implicated in carcinogenesis. We studied the associations of plasma levels of two SPMs [lipoxin A4 (LXA4 ) and resolvin D1(RvD1)] with risk for recurrent adenoma. In this pilot study, we used data and biosamples from an adenoma chemoprevention study investigating the effects of aspirin and/or folic acid on the occurrence of colorectal adenomas...

INTRODUCTION: There have been several reports on arthroscopically assisted removal of the bullet imbedded in hip joint in the literature. Similarly, in this case, a bullet lodged in acetabulum was extracted with arthroscopic technique. What makes this case unique in the literature is that the bullet removed from the acetabulum traversed the femoral neck. CASE REPORT: Male patient aged 32 years with a low-velocity gunshot wound was referred to the emergency room on August 28, 2012...

Septal reduction therapy (SRT) is the accepted therapeutic option for symptomatic hypertrophic obstructive cardiomyopathy (HOCM). At this time, surgical septal myectomy is the gold standard method, but alcohol septal ablation is an acceptable alternative treatment for patients with suitable anatomy. Endocardial septal ablation (ESA) therapy is a little-known method of SRT. Presently described is case of successful ESA procedure performed for HOCM.

OBJECTIVE: An imbalance between parasympathetic and sympathetic tone is a main cause of neurally mediated reflex syncope (NMRS). These patients may be very symptomatic and the condition may require cardiac pacemaker implantation. Cardioneuroablation (CNA) is a relatively novel technique based on radiofrequency ablation of vagal ganglia that can be used in treatment of NMRS. The aim of this analysis was to compare potential role of CNA in patients with NMRS. METHODS: In accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Statement, literature search was conducted using the keywords "cardioneuroablation," "vagal denervation," "reflex syncope," "vagal ablation," and "ganglionic plexi ablation...

REVIEW
Charles N Serhan
Practitioners of ancient societies from the time of Hippocrates and earlier recognized and treated the signs of inflammation, heat, redness, swelling, and pain with agents that block or inhibit proinflammatory chemical mediators. More selective drugs are available today, but this therapeutic concept has not changed. Because the acute inflammatory response is host protective to contain foreign invaders, much of today's pharmacopeia can cause serious unwanted side effects, such as immune suppression. Uncontrolled inflammation is now considered pathophysiologic and is associated with many widely occurring diseases such as cardiovascular disease, neurodegenerative diseases, diabetes, obesity, and asthma, as well as classic inflammatory diseases (e...

Uncovering mechanisms that control immune responses in the resolution of bacterial infections is critical for the development of new therapeutic strategies that resolve infectious inflammation without unwanted side effects. We found that disruption of the vagal system in mice delayed resolution of Escherichia coli infection. Dissection of the right vagus decreased peritoneal group 3 innate lymphoid cell (ILC3) numbers and altered peritoneal macrophage responses. Vagotomy resulted in an inflammatory peritoneal lipid mediator profile characterized by reduced concentrations of pro-resolving mediators, including the protective immunoresolvent PCTR1, along with elevated inflammation-initiating eicosanoids...

Nodular fasciitis is a benign, reactive, tumor-like lesion composed of fibroblasts and myofibroblasts. It typically occurs in the extremities and the trunk. Head and neck localization is 13-20%. As it grows rapidly, clinicians frequently misdiagnose it as an aggressive or a malignant lesion. Some lesions show moderate cellularity, mild cellular atypia, and mitosis histologically causing pathologists to over-diagnose the lesion as a malignant tumor. It is important to diagnose nodular fasciitis correctly to avoid unnecessary additional surgery and treatment...

Sialadenosis is a rare entity characterized by bilateral diffuse, painless swelling of the parotid glands. Its etiology is not clear; however, it may occur due to adverse effects of some drugs. To our knowledge, sialadenosis due to valproic acid has not been reported in the literature up to date in any child. In this article, the authors presented a child who developed sialadenosis due to valproic acid, and improved after stopping use of the drug.

Sudden bilateral hearing loss are seen rarely and the toxic substance exposure constitutes a small part of etiology. A Fifty-eight-year-old woman admitted to our clinic with sudden bilateral hearing loss shortly after chlorpyrifos-ethyl exposure. Otolaryngologic examination findings were normal. The patient had 40 dB sensorineural hearing loss (SNHL) on the right ear and 48 dB SNHL on the left ear. Additional diagnostic tests were normal. The conventional treatment for sudden hearing loss was performed. On the second week following organophosphate (OP) exposure the patient's hearing loss almost completely resolved...

Resolution of acute inflammation is an active process governed by specialized proresolving mediators, including resolvin (Rv)D2, that activates a cell surface G protein-coupled receptor, GPR18/DRV2. In this study, we investigated RvD2-DRV2-dependent resolution mechanisms using DRV2-deficient mice (DRV2-knockout [KO]). In polymicrobial sepsis initiated by cecal ligation and puncture, RvD2 (∼2.7 nmol/mouse) significantly increased survival (>50%) of wild-type mice and reduced hypothermia and bacterial titers compared with vehicle-treated cecal ligation and puncture mice that succumbed at 48 h...

Unresolved inflammation is key in linking metabolic dysregulation and the immune system in type 2 diabetes. Successful regulation of acute inflammation requires biosynthesis of specialized proresolving lipid mediators, such as E-series resolvin (RvE) 1, and activation of cognate G protein-coupled receptors. RvE1 binds to leukotriene B4 (BLT-1) on neutrophils and to ERV-1/ChemR23 on monocyte/macrophages. We show novel actions of RvE1 and expression patterns of neutrophil receptors in type 2 diabetes. Neutrophils from healthy subjects express functional BLT-1, low levels of minimally functional ERV-1, and inversed coexpression when compared to neutrophils from type 2 diabetes subjects...

Transseptal puncture (TSP) may not be possible in cases of an elastic, aneurysmal, or thickened interatrial septum (IAS). During deep inspiration (DI), the chest wall expands and the diaphragm descends. This makes intrapleural pressure to become more negative, which leads to movement of the IAS to the right side. The aim of this study was to verify prospectively the feasibility, safety, and outcome of DI associated with conventional TSP technique in patients with challenging IAS anatomy. From September 2012 to May 2016, 224 patients underwent TSP due to different indications...
