Case ReportsInfluenza A triggered status asthmaticus requiring emergency ECMO.
We describe a case of acute respiratory failure due to severe pneumonia triggered by the influenza A virus, rapidly evolving into a refractory status asthmaticus requiring emergent ECMO assistance, in order to facilitate the clinical management of patients suffering from this rare but life-threatening condition. This case report demonstrates that infection with influenza A virus can present with severe pneumonia and status asthmaticus refractory to medical and ventilatory treatment. When medical treatment and mechanical ventilation fail, extracorporeal membrane oxygenation therapy should not be delayed as it will avoid injury resulting from inadequate mechanical ventilation and lung hyperinflation.

Review Case ReportsTuberculous pericarditis: three cases and brief review.
Tuberculous pericarditis is a form of extrapulmonary tuberculosis that is considered unusual in western coun-tries. Diagnosis is often challenging, while proper treatment has a major impact on prognosis. We present three interesting cases, with complicated or unusual manifestations of tuberculous pericarditis: a patient with cardiac tamponade as the initial manifestation of tuberculosis; a patient progressing to constriction despite adequate treatment; and a patient receiving anti-TNFalpha, who developed pericarditis in the context of immune reconstitution inflammatory syndrome. ⋯ In conclusion, tuberculous pericarditis remains an active thread in the western world. A high index of suspicion combined with the use of all available diagnostic techniques are important to increase diagnostic yield. Prompt and effective treatment is essential to reduce morbidity and mortality.

ReviewLong-term oxygen therapy in COPD: evidences and open questions of current indications.
Long term oxygen therapy (LTOT) has been shown to improve the survival rate in Chronic Obstructive Pulmonary Disease (COPD) patients with severe resting hypoxemia by NOTT and MRC studies, published more than 25 years ago. The improved survival was found in patients who received oxygen for more than 15 hours/day. The effectiveness of LTOT has been documented only in stable COPD patients with severe chronic hypoxemia at rest (PaO2 < 55 mmHg (7.3 kPa) or PaO2 ranging from 56 to 59 mmHg (7.4-7.8 kPa) in presence of signs of Cor Pulmonale, hematocrit > 55%. ⋯ The prescription of oxygen in these circumstances, as for unstable patients, increases the number of patients receiving supplemental oxygen and the related costs. Comorbidities are likely to affect both prognosis and health outcomes in COPD patients, but at the moment we do not know if LTOT in these patients with complex chronic diseases and mild-moderate hypoxemia could be of any use. For these reasons a critical revision of the actual guide lines indications for LTOT in order to optimise effectiveness and costs, and future research in the areas that have not previously been addressed by NOTT and MRC studies, are mandatory.

Predictors and early outcome of prolonged mechanical ventilation in contemporary heart valve surgery.
During last decades mechanical ventilation has been an important support in the postoperative management of patients undergoing cardiac surgery. This study was designed to determine the predictors of prolonged mechanical ventilation (PMV) in patients undergoing heart valve surgery. ⋯ PMV is associated with significant comorbidities and increased hospital mortality. Strategies to delineate the patients at risk and to modify these risk factors by prophylactic measures should probably lead to a lower incidence of prolonged mechanical ventilation for patients undergoing isolated valve surgery.
