BACKGROUND: Chest X-ray (CXR) is a common imaging modality that could impact immediate decision-making for acute chest pathologies. We sought to examine the non-radiologists proficiency of diagnosing acute pathologies manifest on CXR. METHODS: We selected 9 clinical vignettes, each associated with a CXR, wherein only a single acute chest pathology was manifest. We also added a low-risk vignette associated with a normal CXR. We built an electronic survey with the CXR-embedded vignettes and also inquired about the participants' confidence in the diagnosis, and prior exposure to the topics...

Non invasive ventilation (NIV) has a well established role in the treatment of acute-on-chronic respiratory failure and cardiogenic pulmonary oedema. Its role in acute hypoxaemic respiratory failure has been increasingly investigated, but its impact on the management and the outcome of the subset of patients affected by acute respiratory distress syndrome (ARDS) is still to be determined. ARDS could be a risk factor for NIV failure and in these patient delayed endotracheal intubation can lead to an increased mortality...

Increased procoagulant activity in the alveolar compartment and uncontrolled inflammation are hallmarks of the acute respiratory distress syndrome (ARDS). Here, we investigated whether the contact phase system of coagulation is activated and may regulate inflammatory responses in human lungs. Components of the contact phase system were characterized in bronchoalveolar lavage fluids (BALF) from 54 ARDS patients and 43 controls, and their impact on cytokine/chemokine expression in human precision cut lung slices (PCLS) was assessed by a PCR array...

BACKGROUND: Scrub typhus, a potentially fatal rickettsial infection, is common in India. It usually presents with acute febrile illness along with multi-organ involvement caused by Orientia tsutsugamushi. As there was an outbreak of scrub typhus in the Hadoti region of Rajasthan and there is a paucity of data from this region, we studied this entity to describe the diverse epidemiological, clinico-radiological, laboratory parameters and outcome profile of patients with scrub typhus in a tertiary care hospital...

Activation of CXC motif chemokine receptor 4 (CXCR4) has been reported to result in lung protective effects in various experimental models. The effects of pharmacological CXCR4 modulation on the development of acute respiratory distress syndrome (ARDS) after lung injury, however, are unknown. Thus, we studied whether blockade and activation of CXCR4 influences development of ARDS in a unilateral lung ischemia-reperfusion injury rat model. Anesthetized, mechanically ventilated animals underwent right lung ischemia (series 1: 30 min; series 2: 60 min) followed by reperfusion for 300 min...

Zinc chloride smoke bomb exposure is frequently seen in military drills, combat exercises, metal industry works, and disaster simulations. Smoke exposure presents with variety of pulmonary damage based on the intensity of the exposure. Smoke induced severe acute respiratory distress syndrome (ARDS) is often fatal and there are no standard treatment guidelines. We report the first survival of smoke induced severe ARDS in the United States (US) with prolonged use of high dose steroids (five weeks) and lung protective ventilation alone...

The effectiveness of intensive care unit (ICU) care for cancer patients remains controversial. Advances in antitumour and supportive care led to major improvements in outcomes of oncological patients in the ICU. Improved cancer therapies and supportive management of organ dysfunctions have contributed to improved survival rates. As a consequence, the number of cancer patients requiring ICU admission is rising. Frequently, cancer patients have a poor performance status and are vulnerable. It is a heterogeneous population, where the nature and curability of the neoplasm and the severity of critical illness cause a plethora of issues about ICU admissions...

The management of critically ill human immunodeficiency virus (HIV)-positive patients is challenging; however, intensive care unit-related mortality has declined significantly in recent years. There are 10 case reports in the literature of extracorporeal membrane oxygenation (ECMO) use in HIV-positive patients, of whom seven survived to hospital discharge. We describe a 33-year-old Brazilian man who presented with Pneumocystis jirovecii pneumonia and severe hypoxic respiratory failure. He developed refractory acute respiratory distress syndrome (ARDS) and was commenced on veno-venous ECMO...

The aim of this paper is to describe the possibility of using Electrical Impedance Tomography (EIT) as a treatment monitoring tool in the ICU. It was based on case report and literature review. A 19-year-old female was admitted to ICU due to severe acute respiratory distress syndrome. Despite aggressive treatment there was no improvement. We decided to use EIT in the monitoring of treatment because of difficulties in transporting the patient to the radiology department in order to perform a control CT scan...

BACKGROUND: Human metapneumovirus has recently been recognized as an important cause of severe respiratory viral infections and of viral infections in patients admitted to intensive care units. Little is known about the course of this infection in pregnancy. CASE: A late-preterm primigravid woman was admitted to the intensive care unit for acute respiratory distress syndrome and subsequently diagnosed with human metapneumovirus. Because of worsening maternal respiratory status, she was intubated and a primary cesarean delivery was performed...

The extracorporeal CO2 removal device (ECCO2RD) is used in clinics to treat patients suffering from respiratory failures like acute respiratory distress syndrome (ARDS) or chronic obstructive pulmonary disease (COPD). The aim of this device is to decarboxylate blood externally with low blood flow. A mathematical model is proposed to describe protective ventilation, ARDS, and an extracorporeal CO2 removal therapy (ECCO2RT). The simulations are compared with experimental data carried out on ten pigs. The results show a good agreement between the mathematical simulations and the experimental data, which provides a nice validation of the model...

Amiodarone-induced pulmonary toxicity (APT) is a severe side effect that can lead to lung fibrosis or fatal respiratory failure. Usually APT occurs during long term therapy after administration of prolonged loading doses or high cumulative doses. We present the case of a 58 year old woman who underwent thoracic surgery with lobe resection. She developed atrial fibrillation with hemodynamic-instability on the first post-operative day. We initiated amiodarone therapy and four days later she developed respiratory failure...

Acute respiratory distress syndrome (ARDS) is a severe illness characterized by uncontrolled inflammation. The resolution of inflammation is a tightly regulated event controlled by endogenous mediators, such as resolvin D1 (RvD1). Cyclooxygenase-2 (COX-2) has been reported to promote inflammation, along with PGE2, in the initiation of inflammation, as well as in prompting resolution, with PGD2 acting in the later phase of inflammation. Our previous work demonstrated that RvD1 enhanced COX-2 and PGD2 expression to resolve inflammation...
