BACKGROUND: Clinical studies have demonstrated that the early and empiric use of plasma improves survival after hemorrhagic shock. We have demonstrated in rodent models of hemorrhagic shock that resuscitation with plasma is protective to the lungs compared with lactated Ringer's solution. As our long-term objective is to determine the molecular mechanisms that modulate plasma's protective effects in injured bleeding patients, we have used human plasma in a mouse model of hemorrhagic shock...

BACKGROUND AND RATIONALE: Respiratory system involvement in scrub typhus is seen in 20-72% of patients. In endemic areas, good understanding and familiarity with the various radiologic findings of scrub typhus are essential in identifying pulmonary complications. MATERIALS AND METHODS: Patients admitted to a tertiary care center with scrub typhus between October 2012 and September 2013 and had a chest X ray done were included in the analysis. Details and radiographic findings were noted and factors associated with abnormal X-rays were analyzed...

Non-invasive ventilation (NIV) has assumed an important role in the management of acute respiratory failure (ARF). NIV, compared with standard medical therapy, improves survival and reduces complications in selected patients with ARF. NIV represents the first-line intervention for some forms of ARF, such as chronic obstructive pulmonary disease (COPD) exacerbations and acute cardiogenic pulmonary edema. The use of NIV is also well supported for immunocompromised patients who are at high risk for infectious complications from endotracheal intubation...

A 67-year-old man presented at our hospital with severe edema on the left side of his neck, chest and brachial regions. He had a history of right radical nephrectomy due to renal cell carcinoma (RCC, clear cell subtype, stage II) 15 years earlier. Thereafter, metastases to the pancreatic tail and right lung, and left lung metastasis were removed at 8 years and 11 years, respectively, after the nephrectomy. Four years earlier, he had also undergone total gastrectomy for gastric carcinoma (poorly differentiated adenocarcinoma, stage IV) and subsequent maintenance chemotherapy for gastric carcinoma...

BACKGROUND: The optimal timing of surgery in patients with chronic organic severe mitral regurgitation (MR) continues to be debated, especially for those who are asymptomatic. The aim of the study was to determine independent and additive prognostic value of exercise brain natriuretic peptide (eBNP) in patients with severe asymptomatic MR and normal left ventricular ejection fraction (LVEF). METHODS: Two hundred twenty-three consecutive patients with severe MR defined by effective regurgitant orifice (ERO) area ≥ 40 mm(2) and/or residual volume ≥ 60 mL, LVEF > 60%, and normal LV end-systolic diameter < 40 mm underwent symptom limited exercise treadmill test (TMT)...

Catecholamines, including β-adrenergic and dopaminergic neurotransmitters, have an essential role in regulating the "fight or flight" reflex and also affects immune cell proinflammatory action. However, little is known about whether catecholamines prevent dysfunction of metabolic pathways associated with inflammatory organ injury, including development of acute lung injury (ALI). We hypothesize that selected catecholamines may reduce metabolic alterations in LPS-stimulated macrophages and in the lungs of mice subjected to endotoxin-induced ALI, a situation characterized by diminished activity of AMP-activated protein kinase (AMPK)...

On the fifth day after leaving the Parque Nacional El Rey, province of Salta, Argentina, where she made rural tourism, a woman of Italian origin, aged 47, developed an acute fever followed by a petechial and purpuric rash that progressed rapidly to multiorgan failure. She died on the sixth day after hospitalization. There were references to tick bites and a skin lesion similar to tache noire was found. The autopsy showed generalized vasculitis, ascites, pulmonary edema, acute tubular necrosis and portal centrilobular necrosis...

Sepsis is a serious medical problem and is one of the main causes of high mortality in intensive care units. Fifty percent of patients with severe sepsis will develop acute lung injury (ALI). Amentoflavone (AMF) is a polyphenolic compound possessing potent anti-inflammatory activities. The study aimed to explore the protective effects of AMF against ALI in cecal ligation and puncture (CLP)-induced septic rats. The results showed that AMF administration protected against septic ALI, as reflected by marked amelioration of histological injury of lung tissues and decrease of pulmonary edema in CLP-treated rats...

BACKGROUND: Pericardial decompression syndrome is defined as paradoxical hemodynamic instability, left ventricular or bi ventricular systolic dysfunction and pulmonary edema after pericardial fluid drainage. Pericardial Decompression Syndrome is an unexpected clinical scenario with an incidence less than 5% in all surgically or percutaneously managed pericardial tamponade patients. The aim of this manuscript was to describe a case with cardiac tamponade in whom acute biventricular heart failure and pulmonary edema developed after surgical creation of a pericardial window, and to discuss this case in light of the literature...

PURPOSE: Perfluorocarbons (PFCs) can transport 50 times more oxygen than human plasma. Their properties may be advantageous in preservation of tissue viability in oxygen-deprived states, such as in acute lung injury. We hypothesized that an intravenous dose of the PFC emulsion Oxycyte(®) would improve tissue oxygenation and thereby mitigate the effects of acute lung injury. METHODS: Intravenous oleic acid (OA) was used to induce lung injury in anesthetized and instrumented Yorkshire swine assigned to three experimental groups: (1) PFC post-OA received Oxycyte(®) (5 ml/kg) 45 min after oleic acid-induced lung injury (OALI); (2) PFC pre-OA received Oxycyte(®) 45 min before OALI; and (3) Controls which received equivalent dose of normal saline...

During infection, bacteria might generate adaptive responses to facilitate their survival and colonization in the host environment. The alarmone guanosine 5'-triphosphate-3'-diphosphate (ppGpp), the levels of which are regulated by the RelA and SpoT enzymes, plays a critical role in mediating bacterial adaptive responses and virulence. However, the mechanism by which ppGpp regulates virulence-associated traits in Pseudomonas aeruginosa is poorly understood. To investigate the regulatory role of ppGpp, the ppGpp-deficient strain ΔRS (relA and spoT gene double mutant) and the complemented strain ΔRS(++) (complemented with relA and spoT genes) were constructed...

BACKGROUND AND OBJECTIVE: The systemic responses triggered by burns and resuscitative measures may cause pulmonary damage and edema in the acute phase. These effects may occur in the absence of inhalation injury. Currently, there is a paucity of data on the recovery of the respiratory system postburn. This study aimed to examine 10-year hospital service use for respiratory morbidity in children with cutaneous burns and no smoke inhalation injury. METHODS: A population-based longitudinal study with 10-year follow-up using linked hospital and death from Western Australia for children <5 years when hospitalized for a first burn injury (n = 5290) between 1980 and 2012 and a frequency matched noninjury comparison cohort, randomly selected from Western Australia's birth registrations (n = 27 061)...

BACKGROUND: High altitude retinopathy (HAR) includes a number of diseases related to high altitude such as acute mountain sickness (AMS), high altitude pulmonary edema (HAPE) and high altitude cerebral edema (HACE). High altitude retinopathy is mainly characterized by retinal hemorrhages, usually sparing the macular region, a condition specifically known as high altitude retinal hemorrhages (HARH). The pathogenesis of HARH is unclear. Many studies show that lack of oxygen causes an inadequate autoregulation of retinal circulation, causing vascular incompetence...

BACKGROUND Acute pulmonary edema in a pregnant patient is associated with significant morbidity and mortality. Takotsubo syndrome, or stress-induced cardiomyopathy, is a rare cause of acute pulmonary edema in a pregnant patient, especially prior to delivery of the fetus. CASE REPORT We describe a case of a pregnant patient who presented with acute pulmonary edema and eclampsia and was found to have Takotsubo syndrome. To the best of our knowledge, eclampsia as a precipitating factor for Takotsubo syndrome has not been described in literature...

BACKGROUND: The acute respiratory distress syndrome (ARDS) is a life-threating disorder that contributes significantly to critical illness. No specific pharmacological interventions directed at lung injury itself, have proven effective in improving outcome of patients with ARDS. Platelet activation was identified as a key component in ARDS pathophysiology and may provide an opportunity for preventive and therapeutic strategies. We hypothesize that use of acetyl salicylic acid (ASA) may prevent and/ or attenuate lung injury...

Preexisting donor-specific anti-HLA antibodies (DSA) have been associated with reduced survival of lung allografts. However, antibodies with specificities other than HLA may have a detrimental role on the lung transplant outcome. A young man with cystic fibrosis underwent lung transplantation with organs from a suitable deceased donor. At the time of transplantation, there were no anti-HLA DSA. During surgery, the patient developed a severe and intractable pulmonary hypertension associated with right ventricle dysfunction which required artero-venous ECMO...
