This report describes a case of cardiac right auricle rupture (RAR) in a flock of 11,500 broilers that were 14 days old. The birds were housed at an altitude of 300 m, with an external temperature of -10 degrees C and an internal temperature of 15 degrees C. There was 3.6% mortality, due to sudden deaths, from 10 to 14 days of age. All necropsied birds had haemopericardium due to RAR at the point of the junction with the vena cava, and 85% of them had blood in the oral cavity and external acoustic meatus. The vena cava and its caudal branches, the intestinal vessels, and the sinus durae matris and sinus saggitalis were distended. Histological examination showed haemorrhages into the myocardium, degeneration of the cardiac muscle fibres, as well as oedema of the lungs and hypertrophy of the smooth muscle bundles of the parabronchial walls. Blood in the mouth of the broilers may have been due to haemoptysis, which in humans is caused mainly by mitral stenosis. In broilers, mitral stenosis and/or insufficiency, and left ventricular failure with consequent pulmonary hypertension (PH) were considered as possible triggers for right ventricular failure. The alarm reaction in hypoxaemia, due to secondary factors such as cold, caused tachycardia and tachypnoea, may have induced further elevation of PH, and acute myocardial infarction causing cardiac rupture and haemopericardium in this case. Hypertension and PH, due to possible mitral stenosis/insufficiency in association with acute myocardial ischaemia, were probably the determinant factors causing this acute episode. This opens the possibility that the RAR may be cardiogenic.

Current trends in global terrorism mandate that emergency medical services, emergency medicine and other acute care clinicians have a basic understanding of the physics of explosions, the types of injuries that can result from an explosion, and current management for patients injured by explosions. High-order explosive detonations result in near instantaneous transformation of the explosive material into a highly pressurized gas, releasing energy at supersonic speeds. This results in the formation of a blast wave that travels out from the epicenter of the blast. Primary blast injuries are characterized by anatomical and physiological changes from the force generated by the blast wave impacting the body's surface, and affect primarily gas-containing structures (lungs, gastrointestinal tract, ears). "Blast lung" is a clinical diagnosis and is characterized as respiratory difficulty and hypoxia without obvious external injury to the chest. It may be complicated by pneumothoraces and air emboli and may be associated with multiple other injuries. Patients may present with a variety of symptoms, including dyspnea, chest pain, cough, and hemoptysis. Physical examination may reveal tachypnea, hypoxia, cyanosis, and decreased breath sounds. Chest radiography, computerized tomography, and arterial blood gases may assist with diagnosis and management; however, they should not delay diagnosis and emergency interventions in the patient exposed to a blast. High flow oxygen, airway management, tube thoracostomy in the setting of pneumothoraces, mechanical ventilation (when required) with permissive hypercapnia, and judicious fluid administration are essential components in the management of blast lung injury.

A 4-month-old caucasian infant presented non-productive cough, fever associated with hemoptysis, and increasing anemia. He had mild tachypnoea; routine lab tests were normal. The thoracic HRCT scan showed a very large mass in the right lung adherent to the thorax wall, well defined and limiting the medium and upper lobe; the mass was well vascularized, and with central hypodensic areas. Fiberoptic bronchoscopy and bronchoalveolar lavage (BAL) cytology were normal. The definitive histology of the mass showed the presence of inflammatory cells admixed with fibroblasts and rare Touton giant cells in the lesion suggestive of a juvenile xanthogranuloma (JXG) of the lung.

On the emergency department we saw two men aged 19 and 26 with symptoms of lipoid pneumonitis (fire-eater's lung) following aspiration of petroleum during fire-eating. They were both admitted to hospital and treated with amoxicillin and clavulanic acid. Both patients were clinically recovered within a few days. Following aspiration of petroleum there is often a period of latency from 8-24 hours before the symptoms occur; it is recommended that patients should be admitted for observation. Known symptoms are coughing, shortness of breath, thoracic pain, fever, tachypnoea and sometimes haemoptysis. Apart from chest radiographs and laboratory values, taking into account the specific history, unless complications are expected additional diagnostic tests are often considered unnecessary. Treatment is symptomatic: administration of oxygen, pain relief, bronchodilation and potentially antibiotics if a bacterial superinfection is suspected. Clinical recovery is usually quick. Temporary restrictive disorders of lung function and reduced diffusion capacity have been described. Recovery of lung function and radiological recovery are seen within weeks to months. Mortality is less than 1%.

In children, post-obstructive pulmonary edema is a rare condition, caused by a sudden change in upper airway patency. It causes dyspnea, tachypnea, hypoxemia, and at times hemoptysis and respiratory insufficiency. It occurs as a complication in the immediate post-operative period. Pediatricians should be aware of this clinical entity.

A 1-year-old male German shorthaired pointer was referred for evaluation of tachypnea and hemoptysis. A grade VI/VI left basilar continuous murmur was ausculted. Multimodality imaging consisting of thoracic radiographs, transthoracic and transesophageal echocardiography, fluoroscopy-guided selective angiography, computed tomography angiogram (CTA) and magnetic resonance angiogram (MRA), was performed on this patient. The defect included a left-to-right shunting anomalous vessel between the ascending aorta and main pulmonary artery, along with a dissecting aneurysm of the main and right pulmonary artery. An MRA post-processing technique (PC VIPR) was used to allow for high resolution angiographic images and further assessment of the patient's hemodynamics prior to surgical correction. This case report describes the clinical course of a canine patient with a rare form of congenital cardiac disease, and the multiple imaging modalities that were used to aid in diagnosis and treatment.

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.

Kidneys and lungs are the most common organs involved in microscopic polyangiitis (MPA). A retrospective analysis of pediatric MPA patients with pulmonary lesions over the past 10 years was performed to investigate clinical features of MPA in children with pulmonary lesions. There were 9 patients enrolled in our study, including 2 boys and 7 girls, with a median age of 6.6 years at the time of disease onset and a median disease course of 2 months. All of the patients exhibited tachypnea, and 7 exhibited cough and hemoptysis. The most common presentation on pulmonary imaging was ground glass or patchy shadows, which were observed in 6 cases. Seven patients manifested with hematuria and proteinuria, with renal histopathology of fibrinoid necrosis/exudation of the glomerular capillaries. All of the patients presented with normocytic normochromic anemia. Of the 9 patients, 7 were positive for perinuclear antineutrophil cytoplasmic antibody (p-ANCA) and/or myeloperoxidase (MPO), and 2 were positive for p-ANCA/MPO and cytoplasmic ANCA/proteinase 3. Eight patients had normal complement 3 (C3) levels, and one had an elevated C3 level. Five of the 9 patients were positive for antinuclear antibody ANA, and 4 were positive for double strand DNA (ds-DNA) antibody (3 were positive for both). The 7 patients who exhibited renal involvement received steroid plus cyclophosphamide (CTX) treatment. Of these patients, 4 achieved various degrees of remission, 2 were at the beginning of induction therapy, and one was lost to follow-up. Two patients with isolated pulmonary involvement received steroid plus leflunomide treatment and achieved complete remission. Diffuse alveolar hemorrhage was the most frequent presentation of lung involvement in children with MPA, and tachypnea, cough, hemoptysis and anemia were the common clinical symptoms. The majority of these patients exhibited hematuria, proteinuria and renal insufficiency. The efficacy of steroid plus CTX or leflunomide was evident in these patients.

Lipoid pneumonia is an uncommon disease caused by the presence of lipid in the alveoli. Here we described a case of a 50-year-old woman with haemoptysis, cough and tachypnea, who was diagnosed with cholesterol pneumonia accompanying with pulmonary artery hypertension. The extremely high pulmonary artery pressure achieved, in this case, is alarming and should alert the physicians that the cholesterol pneumonia may be one of the underlying causes of pulmonary artery hypertension. After a treatment of methylprednisolone, her clinical symptoms were significantly improved, which suggested that steroid might be a promising therapeutic for patients with cholesterol pneumonia.

Pulmonary embolism is considered a rare disease in India. The diagnosis is likely to be missed as its presentation is often enigmatic. Ten cases of pulmonary embolism are presented. Nine patients presented with acute pulmonary embolism, while one had chronic pulmonary emboli with cor pulmonale. The diagnosis was based on pulmonary angiography (1 case), lung perfusion/ventilation scan (2 cases), autopsy (2 cases) and characteristic ECG, X-ray chest and clinical features (5 cases). The initial diagnosis was often incorrect (7/10 cases). Common presenting clinical features were: sudden breathlessness (10/10), tachypnoea (10/10) and tachycardia (8/10); chest pain (3/10) was uncommon and hemoptysis was not seen in any patient. ECG revealed isolated sinus tachycardia in 2 cases, S1 Q3 T3 pattern in 2, and right axis with ST-T wave changes in 5 patients. X-ray chest showed either an area of oligemia or non-specific opacities in 7 patients and was normal in three cases. Advances in specific diagnostic modalities coupled with heightened awareness should contribute to an early detection of pulmonary embolism, rarity of which may be more apparent than real.
