Pheochromocytomas are rare neoplasias of the adrenal medulla which generally present with paroxysmal or sustained hypertension. Cardiogenic pulmonary edema is a common feature of these tumors, but few cases have been described with noncardiogenic pulmonary edema. We report a pheochromocytoma with the principle manifestation of noncardiogenic pulmonary edema and characterize a genetic lesion associated with the disorder. A 30-year-old man was admitted with abdominal pain and breathlessness. x-Ray examination of the chest revealed a massive, diffuse infiltration of the left lung without cardiomegaly. No paroxysmal blood pressure fluctuations or heart failure were evident during the entire course, and the infiltrate and dyspnea resolved in three days without inotropic or diuretic agents. Serum norepinephrine and epinephrine levels were elevated twenty and fifty times above normal, respectively. The patient was ultimately diagnosed with multiple endocrine neoplasia type 2A (MEN 2A). Mutations in the RET proto-oncogene have been described recently in patients with MEN 2A. Mutation analysis of selected RET exonic sequences identified a germline mutation at codon 634 in exon 11 of the RET proto-oncogene. The mutation introduces a transition encoding a non-conservative substitution from TGC (Cys) to CGC (Arg) and creates a novel restriction site recognized by HhaI. We further screened for this mutation among four of the proband's relatives by HhaI restriction analysis. One asymptomatic family member was identified who subsequently elected prophylactic total thyroid removal. Histological examination of this specimen confirmed the presence of medullary thyroid carcinoma.

Noninvasive ventilation (NIV) is a safe and effective technique that can prevent side effects and complications related to endotracheal intubation. Acute cardiogenic pulmonary edema is currently the second most common indication for NIV, mainly in emergency departments. In this article we examine recent literature related to the applications of NIV in the acute setting with regard to patients with acute cardiogenic pulmonary edema. In addition, we examine the epidemiology and the pathophysiology of acute heart failure.

Acute cardiogenic pulmonary edema (CPE) is a pathology frequently seen in patients presenting to emergency departments (EDs) and can usually be attributed to preexisting cardiovascular disease. Heart failure alone accounts for more than 1 million hospital admissions annually and has one of the highest ED morbidity and mortality to date (). Historically, CPE has been managed by the treating clinician in a manner that is based largely on anecdotal evidence. Furosemide (Lasix), morphine, and nitroglycerin have historically been the baseline standard for drug therapy in CPE management. A lack of drastic improvement in the patient's condition over the course of the ED visit may reflect a management style that results in higher morbidity and mortality for CPE patients. Several recent articles provide evidence-based outcomes that suggest changing standard therapy along with the adjunctive use of other medications. These articles also describe treatment modalities that result in a marked improvement in the management of patients with CPE along with decreases in adverse outcomes and hospital length of stay. The goal of this article is to present a summary of the evidence regarding the management of CPE and discuss the implications for current practice.

Acute cardiogenic pulmonary edema and cardiogenic shock are two of the main forms of presentation of acute heart failure. Both entities are serious, with high mortality, and require early diagnosis and prompt and aggressive management. Acute pulmonary edema is due to the passage of fluid through the alveolarcapillary membrane and is usually the result of an acute cardiac episode. Correct evaluation and clinical identification of the process is essential in the management of acute pulmonary edema. The initial aim of treatment is to ensure hemodynamic stability and to correct hypoxemia. Other measures that can be used are vasodilators such as nitroglycerin, loop diuretics and, in specific instances, opioids. Cardiogenic shock is characterized by sustained hypoperfusion, pulmonary wedge pressure > 18 mmHg and a cardiac index < 2.2l/min/m(2). The process typically presents with hypotension (systolic blood pressure < 90 mmHg or a decrease in mean arterial pressure > 30 mmHg) and absent or reduced diuresis (< 0.5 ml/kg/h). The most common cause is left ventricular failure due to acute myocardial infarction. Treatment consists of general measures to reverse acidosis and hypoxemia, as well as the use of vasopressors and inotropic drugs. Early coronary revascularization has been demonstrated to improve survival in shock associated with ischaemic heart disease.

Cardiogenic pulmonary edema is a common presentation of acute heart failure normally treated with continuous positive airway pressure (CPAP), diuretics and nitrates. This therapy is contraindicated in case of cardiac tamponade. We describe a case of pulmonary edema due to cardiac tamponade in which integrated lung-heart ultrasound examination allowed prompt diagnosis and pericardiocentesis before administration of CPAP thus avoiding circulatory collapse.
