Transfusion-related acute lung injury (TRALI) is an underdiagnosed and underreported syndrome which by itself is the third leading cause of transfusion-related mortality. The incidence of TRALI is reported to be 1 in 2000 to 5000 transfusions. When combined with uncontrollable bleeding, survival is unachievable. We report the case of a 25-year-old man, who underwent open heart surgery as an infant to correct his congenital heart disease in association with right pulmonary artery atresia. He presented with hemoptysis secondary to aspergilloma and required a pneumonectomy of the nonfunctional right lung. During pneumolysis, significant bleeding occurred from the superior vena cava. The patient required a blood transfusion and was placed on cardiopulmonary bypass to control the bleeding. Simultaneous occurrence of severe pulmonary edema and retroperitoneal bleeding were noted. Approximately 8 L of frothy edema fluid were drained from the only functional left lung starting ~15 minutes after the transfusion and lasting for several hours until the end of the case. It most likely represented TRALI syndrome. Increasing abdominal girth and poor volume return to the pump were consistent with and pathognomonic for retroperitoneal bleeding. Though primary surgical bleeding in the chest was controlled successfully and a pneumonectomy performed without further difficulty, we were unable to separate the patient from cardiopulmonary bypass due to the inability to oxygenate. As a result, we could not reverse the anti-coagulation which potentially exacerbated the retroperitoneal bleeding. After multiple unsuccessful attempts the patient succumbed. This ill-fated case demonstrates the quandary of obtaining vascular access for emergency cardiopulmonary bypass while in the right thoracotomy position. It may be beneficial to have both the femoral artery and vein cannulated before positioning a patient in a lateral decubitus position. In addition, early direct access to the right atrium may obviate a need for femoral venous cannulation. Also, adult extracorporeal membrane oxygenation may be indicated if faced with such a severe pulmonary edema without ongoing hemorrhage.

We report five patients who presented to an on-site medical team with concurrent haemoptysis and shortness of breath at a recent triathlon event. After initial management in the field, three of the five patients were transported to hospital via ambulance for further management, resulting in patients with haemoptysis and dyspnoea being 17 times more likely to require hospital transport. It is important to consider the differential diagnoses for this presentation, particularly exercise-induced pulmonary oedema.

A previously healthy woman in her early 20s presented in week 38 of pregnancy with a 2-week history of haemoptysis, positional dyspnoea and an examination suggestive of pulmonary oedema. A chest CT showed a left lower lobe lung mass invading through the inferior pulmonary vein into the left atrium and abutting the posterior mitral leaflet. Pulmonary oedema consequent on left inferior pulmonary vein occlusion was initially restricted to the left lower lobe, but progressed to involve the contralateral lung following extension of the mass to the mitral orifice, resulting in functional mitral stenosis. A biopsy was positive for poorly differentiated spindle cell neoplasm. This is the first reported case of a pregnant patient with spindle cell neoplasm of lung and of a spindle neoplasm causing mitral stenosis, as well as the youngest known case of this disease.

Haemoptysis and pulmonary oedema following deep breath-hold diving have been described in recent years. We describe the case of a 33-year-old healthy military diver who presented symptoms suggestive of pulmonary oedema after two breathhold dives, the first lasting 0.5-1 min and the second 1-2 min, to 6 metres' depth in the sea. The diagnosis was promptly confirmed with chest computed tomography showing bilateral interstitial infiltrates in the upper regions of the lungs. To our knowledge, this is the first report to document pulmonary oedema in this setting of shallow breath-hold diving with atypical radiological presentation. A definite mechanism for this specific distribution of lung injury remains unclear.

Damage to lungs may occur from systemic as well as inhalational exposure to various illegal drugs of abuse. Aspiration pneumonia probably represents the most common pulmonary complication in relation to consciousness impairment. Some pulmonary consequences may be specifically related to one given drug. Prolonged smoking of marijuana may result in respiratory symptoms suggestive of obstructive lung disease. Non-cardiogenic pulmonary edema has been attributed to heroin, despite debated mechanisms including attempted inspiration against a closed glottis, hypoxic damage to alveolar integrity, neurogenic vasoactive response to stress, and opiate-induced anaphylactoid reaction. Naloxone-related precipitated withdrawal resulting in massive sympathetic response with heart stunning has been mistakenly implicated. In crack users, acute respiratory syndromes called "crack-lung" with fever, hemoptysis, dyspnea, and pulmonary infiltration on chest X-rays have been reported up-to 48h after free-base cocaine inhalation, with features of pulmonary edema, interstitial pneumonia, diffuse alveolar hemorrhage, and eosinophil infiltration. The high-temperature of volatilized cocaine and the presence of impurities, as well as cocaine-induced local vasoconstriction have been suggested to explain alveolar damage. Some other drug-related pulmonary insults result from the route of drug self-administration. In intravenous drug users, granulomatous pneumonia with multinodular patterns on thoracic imaging is due to drug contaminants like talcum. Septic embolism from right-sided endocarditis represents an alternative diagnosis in case of sepsis from pulmonary origin. Following inhalation, pneumothorax, and pneumomediastinum have been attributed to increased intrathoracic pressure in relation to vigorous coughing or repeated Valsalva maneuvers, in an attempt to absorb the maximal possible drug amount. In conclusion, pulmonary consequences of illicit drugs are various, resulting in both acute life-threatening conditions and long-term functional respiratory sequelae. A better understanding of their spectrum and the implicated mechanisms of injury should help to improve patient management.

Diffuse alveolar hemorrhage (DAH) can be caused by several etiologies including vasculitis, drug exposure, anticoagulants, infections, mitral valve stenosis, and regurgitation. Chronic mitral valve regurgitation (MR) has been well documented as an etiological factor for DAH, but there have been only a few cases which have reported acute mitral valve regurgitation as an etiology of DAH. Acute mitral valve regurgitation can be a life-threatening condition and often requires urgent intervention. In rare cases, acute mitral regurgitation may result in a regurgitant jet which is directed towards the right upper pulmonary vein and may specifically cause right-sided pulmonary edema and right-sided DAH. Surgical repair of the mitral valve results in rapid resolution of DAH. Acute MR should be considered as a possible etiology in patients presenting with unilateral pulmonary edema, hemoptysis, and DAH.

We report the case of a 75-year old woman who presented with shortness of breath and haemoptysis. She had been treated for presumed essential hypertension for many years. On admission she was found to be severely hypertensive. Chest X-ray showed pulmonary oedema. However, an echocardiogram reported good systolic ventricular function. Her hypertension and pulmonary oedema did not respond to medical treatment necessitating intubation. A CT angiogram identified the cause--undiagnosed bilateral severe. We discuss this increasingly common condition that is difficult to manage and easily missed.

Pulmonary manifestations of hyperthyroidism not only include pulmonary hypertension and hydrostatic pulmonary oedema, but also treatment/drug-associated pulmonary diseases have to be considered as an exclusion diagnosis. A 27-year-old woman with hypoxaemic respiratory failure under an arterial-venous extra-corporeal membrane oxygenator (AV-ECMO) was admitted to the intensive care unit (ICU). The patient had progressive dyspnoea with haemoptysis, palpitations and failure to thrive. The patient had Graves' disease treated previously with propylthiouracil (PTU). Diffuse alveolar haemorrhage is a non-specific syndrome characterised by evidence of diffuse alveolar damage, exclusion of infectious aetiology and progressively bloodier bronchoalveolar lavage (and/or 20% hemosiderin laden macrophages on cytological examination). PTU associated perinuclear antineutrophil cytoplasmic antibodies (p-ANCA) vasculitis appears to be more common in younger female patients presenting with leukocytoclastic vasculitis, myalgias and arthralgias. The latter compared to non-drug associated ANCA vasculitis which are more common in older males with visceral involvement. PTU-induced ANCA vasculitis prognosis appears to be better compared to primary ANCA syndromes.

Propofol is frequently used in the emergency department to provide procedural sedation for patients undergoing various procedures and is considered to be safe when administered by trained personnel. Pulmonary edema after administration of propofol has rarely been reported. We report a case of a 23-year-old healthy male who developed acute cough, hemoptysis and hypoxia following administration of propofol for splinting of a foot fracture. Chest radiography showed bilateral patchy infiltrates. The patient was treated successfully with supportive care. This report emphasizes the importance of this potentially fatal propofol-associated complication and discusses possible underlying mechanisms and related literature.

Pulmonary embolism in children is a rare condition, associated with high mortality. Clinical presentation is nonspecific. Pulmonary embolism may present initially similar to bacterial endocarditis of the right heart, septic thrombophlebitis, or osteomyelitis. We report the case of a 6-year-old girl who had dyspnea over the four months before consultation, complicated three months later by hemoptysis. She was diagnosed with subacute bacterial endocarditis secondary to group D Streptococcus, developed upon a ventricular septal defect. Two weeks later, the child had sudden chest pain and tachypnea. Lung scintigraphy showed multiple pulmonary embolisms. The therapeutic approach was to continue antibiotics without anticoagulant treatment. The outcome was favorable with apyrexia and stabilization on the respiratory level. Pulmonary embolism is a rare disease in children with an incidence of 3.7%. Classically, it presents with fever, hemoptysis, and nonspecific infiltrates on chest X-ray. These signs were noted in our patient, although the infiltrates on the chest X-ray were hidden by the pulmonary edema associated with heart failure. The persistence of these left basal opacities after antidiuretic treatment suggested an infectious origin. Subsequently, lung scintigraphy showed that it was a pulmonary infarct. The therapy of septic pulmonary embolism is the same as that for infective endocarditis. Antibiotic treatment alone was maintained without anticoagulants because of the high risk of bleeding at the seat of the pulmonary embolism and the insubstantial significant benefit of this therapy. Pulmonary embolism in children is a rare disease, but its incidence is underestimated. Better knowledge on its actual impact and etiologies in children is necessary. Multicenter studies are needed to establish recommendations.
