Multicenter Study Observational Study
Utility of point-of-care biliary ultrasound in the evaluation of emergency patients with isolated acute non-traumatic epigastric pain.
To determine the utility of emergency physician-performed point-of-care biliary ultrasound in the evaluation of emergency department (ED) patients with isolated acute non-traumatic epigastric pain. This was a multi-center prospective observational study of adult patients presenting to the ED with isolated acute non-traumatic epigastric pain. Patients with abdominal tenderness at any site other than the epigastric region, or with a history of gall stones, cholecystectomy, gastrointestinal bleeding, chronic abdominal pain, trauma, or altered mental status were excluded. ⋯ Point-of-care biliary ultrasound detected gall stones in more than one-third of ED patients with isolated acute non-traumatic epigastric pain. All patients presenting to the ED with non-traumatic epigastric pain should be evaluated for biliary disease with an ultrasound imaging study. Bedside ultrasound can avoid misdiagnosis and expedite management in these patients.

COPD patients with and without metabolic syndrome: clinical and functional differences.
Chronic obstructive pulmonary disease (COPD) and the metabolic syndrome (MetS) are considered public health challenges of the 21st century. The coexistence of MetS in COPD patients and any clinical differences between COPD patients with and without MetS have not been extensively studied. We aimed to describe the clinical characteristics of patients with MetS and COPD. ⋯ They had been hospitalized more frequently for any cause but not for COPD. In multivariate analysis, the presence of MetS was independently associated with greater FEV1, inhaled steroids use, osteoporosis, diabetes, and heart failure. MetS is a frequent condition in COPD patients, and it is associated with greater FEV1, more dyspnea, and more comorbidities.

Drug-induced angioedema: experience of Italian emergency departments.
Acute angioedema represents a cause of admission to the emergency department requiring rapid diagnosis and appropriate management to prevent airway obstruction. Several drugs, including angiotensin-converting enzyme inhibitors (ACE-I), nonsteroidal anti-inflammatory drugs (NSAIDs) and oral antidiabetics, have been reported to induce angioedema. The aim of this prospective observational study conducted in a setting of routine emergency care was to evaluate the incidence and extent of drug-induced non-histaminergic angioedema in this specific clinical setting, and to identify the class of drugs possibly associated with angioedema. ⋯ Of the remaining patients, 15 received antibiotic treatment and 10 antihypertensive treatment. In addition, we observed in our series some cases of angioedema associated with drugs (such as antiasthmatics, antidiarrheal and antiepileptics) of which there are few descriptions in the literature. The present data, which add much needed information to the existing limited literature on drug-induced angioedema in the clinical emergency department setting, will provide more appropriate diagnosis and management of this potentially life-threatening adverse event.

Smoking is associated with increased morbidity and mortality in cardiac patients. However, data on the prognostic impact of smoking in heart failure (HF) patients on cardiac resynchronization therapy with defibrillator (CRT-D) are absent. We investigated the effects of smoking on all-cause mortality and on a composite endpoint (all-cause death/appropriate device therapy), appropriate and inappropriate device therapy, in 649 patients with HF who underwent CRT-D between January 2003 and October 2011 in 6 Centers (4 in Italy and 2 in USA). 68 patients were current smokers, 396 previous-smokers (patients who had smoked in the past but who had quit before the CRT-D implant), and 185 had never smoked. ⋯ After adjusting for age, left ventricular ejection fraction, QRS width and ischemic etiology, both current and previous smoking were independent predictors of all-cause death [HR = 5.07 (95 % CI 2.68-9.58), p < 0.001 and HR = 2.43 (95 % CI 1.38-4.29), p = 0.002, respectively) and of composite endpoint [HR = 1.63 (1.04-2.56); p = 0.033 and HR = 1.46 (1.04-2.04) p = 0.027]. In addition, current smokers had a significantly higher rate of inappropriate device therapy compared to never smokers [HR = 21.74 (4.53-104.25), p = 0.005]. Our study indicates that in patients with HF who received a CRT-D device, current and previous smoking increase the event rate per person-time of death and of appropriate and inappropriate ICD therapy more than other known negative prognostic factors such as age, left ventricular dysfunction, prolonged QRS duration and ischemic etiology.

The IRYSS-COPD appropriateness study was developed in 16 hospitals belonging to the Spanish National Health Service from June 2008 to September 2010 (n = 2,877). The objectives were to apply a set of explicit criteria for the appropriateness of hospital admission created by the RAND/UCLA methodology to patients evaluated in the emergency department (ED) for exacerbations of COPD. This is a prospective cohort study. ⋯ Among patients classified by the explicit criteria as appropriate for hospital admission, 81.3 % were admitted, compared with 64.81 % of those classified as uncertain and 48.65 % of those classified as inappropriate for admission. Severity of exacerbation was the most influencing variable in the decision. Application of our explicit criteria for appropriate hospital admission among a large sample of patients experiencing an exacerbation of COPD in the ED setting suggests that these criteria could be used as the basis for clinical decision-making and health-care assessment.
