We performed a systematic review of the literature to establish conclusive evidence of risk factors for community-acquired pneumonia (CAP). Observational studies (cross-sectional, case-control, and cohort studies) the primary outcome of which was to assess risk factors for CAP in both hospitalized and ambulatory adult patients with radiologically confirmed pneumonia were selected. The Newcastle-Ottawa Scale specific for cohort and case-control designs was used for quality assessment. Twenty-nine studies (20 case-control, 8 cohort, and 1 cross-sectional) were selected, with 44...

Middle East respiratory syndrome-coronavirus (MERS-CoV) resembles a severe form of community-acquired pneumonia initially reported in Saudi Arabia in 2012. The MERS-CoV epidemic poses a big challenge because of its high mortality. In January 2015, a patient who was potentially incubating MERS-CoV arrived from the emergency department of another hospital and was admitted with acute coronary syndrome. This resulted in an outbreak in the cardiac surgery ward that caused the deaths of 5 of 6 patients who had undergone cardiac operations...

Mycoplasma pneumoniae (M. pneumoniae) is a major cause of community acquired respiratory infections. And it also causes a number of extrapulmonary manifestations including cardiovascular, dermatological, musculoskeletal, and hematological systems. But, acute hepatitis without lung involvement is rare in adults. Here, we report a case of 32-year-old man who presented with fever, chilling, myalgia, and headache. Biochemical analysis showed severely impaired liver function and leukopenia. Laboratory tests and liver biopsy demonstrated a hepatocellular pattern of M...

In spite of many attempts to differentiate bacterial from viral disease and predict severity and outcome, the etiologic diagnosis of paediatric community acquired pneumonia and the estimation of potential outcomes remain unsolved problems in most cases. Mycoplasma pneumoniae is one of the major pathogens causing CAP in children. Although MP infection was traditionally thought to be a self-limited process, more and more severe cases even fatal cases of MP infections were reported in recent years. So it is essential for pediatricians to recognize severe or refractory or severe MP early, treat it promptly and prevent the progress of the disease...

RATIONALE: Splenosis is the development of one or more heterotopic splenic tissue autoimplants following rupture of the spleen and remains mostly asymptomatic. PATIENT CONCERNS: We report a case of a 50-year old post-traumatic splenectomized man admitted for a left side community acquired pneumonia resistant to antibiotics. DIAGNOSES: The diagnosis of intrathoracic ectopic spleen was suspected because of the history of spleen trauma with diaphragm rupture and the absence of Howell-Jolly bodies...

INTRODUCTION: Antibiotics represent one of the most widely prescribed therapeutic agents in children. It has been estimated that 30-50% of antibiotic prescriptions for this population are inappropriate. In this scenario, analysis of prescription data provides an invaluable source of information as a basis for implementing strategies for improvement in this field. OBJECTIVE: To assess the appropriateness of antibiotic prescriptions in a paediatric population at an emergency department...

REVIEW
Margarita E Pena, Viviane M Kazan, Michael N Helmreich, Sharon E Mace
In adults, respiratory disorders are the second most frequent diagnoses treated in emergency department observation units (EDOUs) and account for the most frequent indication for placement of pediatric patients into an EDOU. With appropriate patient selection, chronic obstructive pulmonary disease exacerbations, and community-acquired pneumonia can be managed in the EDOU. EDOU management results in equivalent or better outcomes than inpatient care with decreased length of stay, increased patient satisfaction, lower cost and in some studies decreased mortality...

OBJECTIVES: Community-acquired pneumonia (CAP) is associated with a high risk of respiratory failure or septic organ dysfunction. Lactate is an established early marker of prognosis and sepsis severity, but few data exist in patients with CAP. METHODS: We performed a retrospective cohort study of consecutive adult CAP patients without treatment restrictions or direct ICU admission. Lactate was measured as point of care test within the capillary admission blood gas analysis and its prognostic value was compared to the CRB/CURB-65 criteria by multivariate and ROC curve analysis...
