BACKGROUND Pulmonary edema is the accumulation of fluid in the lung secondary to increased hydrostatic pressure. Hypertensive cardiogenic pulmonary edema presents with a sudden onset of severe dyspnea, tachycardia, and tachypnea, and can occur when the systolic blood pressure exceeds 160 mmHg in association with acute decompensated congestive cardiac failure (CCF). A case is presented of hypertensive cardiogenic pulmonary edema treated with high-dose nitroglycerin and includes a review of the literature. CASE REPORT A 63-year-old Hispanic male with a medical history of hypertension, coronary artery disease, heart failure with a reduced ejection fraction of 35%, chronic kidney disease (CKD) and diabetes mellitus, presented as an emergency with acute, severe dyspnea...

Headaches are highly disabling and are among the most common neurological disorders worldwide. Despite the high prevalence of headache, therapeutic options are limited. We recently identified the delta opioid receptor (DOR) as an emerging therapeutic target for migraine. In this study, we examined the effectiveness of a hallmark DOR agonist, SNC80, in disease models reflecting diverse headache disorders including: chronic migraine, post-traumatic headache (PTH), medication overuse headache by triptans (MOH), and opioid-induced hyperalgesia (OIH)...

An 83-year-old man with a previous right coronary artery (RCA) stent presented to the emergency department with syncope, dynamic lateral ST depression, and a serum troponin of 6148 ng/L (< 17). Coronary angiography revealed a patent proximal RCA stent and significant left-sided disease. The procedure was complicated by inferior ST elevation, urticaria, hypotension, and acute proximal RCA occlusion. This required stenting, which acted as a scaffold to ameliorate subsequent vasospasm that responded to intracoronary glyceryl trinitrate...

A 79-year-old man with a heavy smoking history presented with threatened lower limbs due to acute exacerbation of peripheral artery disease (PAD). He underwent emergent distal bypass surgery for the right leg and external iliac stenting for the left leg. Fatal coronary artery spasm (CAS) with ST segment changes on electrocardiography was observed 28 h after the procedures, resulting in cardiac arrest. Coronary angiography showed widespread CAS with improvement after intra-arterial nitroglycerin infusion. We should keep in mind that CAS may occur more frequently than expected in PAD patients, especially those who have not stopped smoking prior to revascularization...

Coronary spastic angina (CSA) is relatively more common in young people than in elderly people. Here, we present three cases of elderly male patients who experienced out-of-hospital cardiac arrest (OHCA) likely due to coronary spasm-induced ventricular fibrillation (Vf) from 2013 to 2016. After defibrillation, emergency coronary arteriography demonstrated severe coronary vasospasm that resolved following intracoronary infusion of nitroglycerin in the right coronary arteries in all three patients, with no organic obstructive lesion in the coronary arteries after nitroglycerin infusion...

BACKGROUND: Acute heart failure (AHF) is a common presentation to the emergency department (ED), with the potential to cause significant morbidity and mortality. It is important to tailor treatments to the appropriate type of heart failure. OBJECTIVES: This review provides an evidence-based summary of the current ED management of acute heart failure. DISCUSSION: Heart failure can present along a spectrum, especially in acute exacerbation. Treatment should focus on the underlying disease process, with guidelines focusing primarily on blood pressure and hemodynamic status...

Burrowing, or the removal of material from an enclosed tube, is emerging as a prominent means of testing changes in a voluntary behavior in rodent models of various pain states. Here, we report no significant differences between male and female mice in terms of burrowing performance, in a substantially shorter time frame than previous reports. We found that the color of the burrow tube affects the variability of burrowing performance when tested in a lit room, suggesting that light aversion is at least a partial driver of this behavior...

Background: Quorum sensing is a cell-to-cell communication system in bacteria that controls the production of virulence factors. Serratia marcescens is a causative agent of hospital-acquired infections that shows high resistance to antibiotics. This makes the treatment of these infections difficult. Quorum sensing regulates the production of virulence factors of S. marcescens such as prodigiosin, protease, swimming and swarming motilities and formation of biofilms. Inhibition of quorum sensing may be an alternative to antibiotic treatment to avoid emergence of resistance...

BACKGROUND: Uterine tachysystole (more than 5 contractions per 10 minutes in 2 consecutive intervals) is common during labour, particularly with use of labour-stimulating agents. Tachysystole may reduce fetal oxygenation by interrupting maternal blood flow to the placenta during contractions. Reducing uterine contractions may improve placental blood flow, improving fetal oxygenation. This review aimed to evaluate the use of tocolytics to reduce or stop uterine contractions for improvement of the condition of the fetus in utero...

Acute pulmonary edema due to sympathetic surge and increased peripheral vascular resistance often present to the emergency department (ED) with markedly elevated blood pressure, severe dyspnea, and desaturation. This condition is known as "SCAPE" (sympathetic crashing acute pulmonary edema). We present three SCAPE patients who were successfully treated with high-dose nitroglycerin (NTG) and bilevel positive airway pressure (BiPAP) ventilation. All three patients presented with respiratory failure on arrival but rapidly improved after treatment and did not require endotracheal intubation or admission to the intensive care unit (ICU)...

INTRODUCTION: Acute heart failure (AHF) accounts for a significant number of emergency department (ED) visits, and the disease may present along a spectrum with a variety of syndromes. OBJECTIVE: This review evaluates several misconceptions concerning heart failure evaluation and management in the ED, followed by several pearls. DISCUSSION: AHF is a heterogeneous syndrome with a variety of presentations. Physicians often rely on natriuretic peptides, but the evidence behind their use is controversial, and these should not be used in isolation...

BACKGROUND: Takotsubo cardiomyopathy or stress cardiomyopathy is characterized by transient left ventricular apical ballooning in the absence of coronary occlusion. The underlying pathophysiological mechanism is still unclear but possible causes have been proposed mainly catecholamine cardiotoxicity, followed by metabolic disturbance, coronary microvascular impairment, and multivessel epicardial coronary artery vasospasm. Takotsubo cardiomyopathy accounts for 1-2% of patients presenting with acute coronary syndrome with the majority of patients diagnosed with Takotsubo cardiomyopathy being women > 55 years of age...

OBJECTIVE: Hypertensive emergencies are potentially life threatening and require prompt blood pressure control with intravenous agents. Preparation of intravenous infusions is time consuming. Usefulness of sublingual nitroglycerin in this setting is not known. We aimed to assess the benefit of sublingual nitroglycerin as a bridge to IV therapy. In a clinical audit in an emergency department, patients presenting with hypertensive emergencies requiring intravenous nitroglycerin were administered single spray of sublingual nitroglycerin awaiting commencement of intravenous infusion...

RATIONALE: Brain metastasis of choriocarcinoma is a highly malignant gestational trophoblastic neoplasia (GTN) and has a notoriously poor prognosis. Hemorrhagic choriocarcinoma lesions may lead to life-threatening conditions also. Treatment of brain metastases of choriocarcinoma with hemorrhage in multiple sites is very difficult in clinical practices. A patient has been successfully treated in our hospital, which provides as clinical references for this difficulty in treating brain metastases of choriocarcinoma with hemorrhage in multiple sites...

INTRODUCTION: Endovascular aortic interventions are suitable alternatives to open surgery, being less invasive and having lower mortality and complications. Accurate positioning of the stent graft is a critical point because of systolic thrush. Techniques used to prevent it include pharmacological (antihypertensive drugs, nitroglycerin, adenosine) and mechanical methods (temporary caval occlusion by balloon). Rapid Right Ventricular Pacing (RRVP) is an emerging alternative with good patient tolerance and low level of complications...

BACKGROUND AND AIMS: Circulating endothelial microparticles (EMPs) are increased in arterial hypertension. The role of physicomechanical factors that may induce EMP release in vivo is still unknown. We studied the relationship of EMPs and physicomechanical factors in stable arterial hypertension and hypertensive emergencies, and investigated the pattern of EMP release after mechanical endothelial injury. METHODS: In a pilot study, 41 subjects (50% hypertensives) were recruited...

BACKGROUND: Esophageal food impaction is a common illness presenting to emergency departments (ED), and is frequently resistant to pharmacologic therapy. Several medications have been promoted for this indication, but so far have not proven effective. Endoscopic removal is frequently required to resolve the impaction, resulting in risks from anesthesia and the physical procedure, and in prolonged hospital stay for recovery. Oral nitroglycerin solution was recently used in two such cases and may represent a new therapeutic option...
