Idiopathic acute eosinophilic pneumonia (IAEP), characterized by acute febrile respiratory failure associated with diffuse radiographic infiltrates and pulmonary eosinophilia, is rarely reported in children. Diagnosis is based on an association of characteristic features including acute respiratory failure with fever, bilateral infiltrates on the chest X-ray, severe hypoxemia and bronchoalveolar lavage fluid >25% eosinophils or a predominant eosinophilic infiltrate in lung biopsies in the absence of any identifiable etiology. We present a 14-month-old girl who was admitted to our pediatric intensive care unit because of acute respiratory distress. She had a fever, dry cough, and progressive dyspnea for 1 day. Chest X-ray showed multifocal consolidations, increased interstitial markings, parenchymal emphysema and pneumothorax. IAEP was confirmed by marked pulmonary infiltrates of eosinophils in the lung biopsy specimen. Most known causes of acute eosinophilic pneumonia, such as exposure to causative drugs, toxins, second-hand smoking and infections were excluded. Her symptoms were resolved quickly after corticosteroid therapy.

Not a few patients in children and adolescents are suffering from right ventricular (RV) dysfunction resulting from various conditions such as chronic lung disease, left ventricular dysfunction, pulmonary hypertension, or congenital heart defect. The RV is different from the left ventricle in terms of ventricular morphology, myocardial contractile pattern and special vulnerability to the pressure overload. Right ventricular failure (RVF) can be evaluated in terms of decreased RV contractility, RV volume overload, and/or RV pressure overload. The management for RVF starts from clear understanding of the pathophysiology of RVF. In addition to correction of the underlying disease, management of RVF per se is very important. Meticulous control of volume status, inotropic agents, vasopressors, and pulmonary selective vasodilators are the main tools in the management of RVF. The relative importance of each tool depends on the individual clinical status. Medical assist device and surgery can be considered selectively in case of refractory RVF to optimal medical treatment.

Acute respiratory failure has become an increasingly frequent cause of death following shock or trauma. Interstitial or diffuse alveolar edema, as chief pathophysiologic change of acute respiratory insufficiency, can be the result of sepsis, fat embolism, cardiac failure, lung congestion, and oxygen toxicity. These pulmonary problems are extremely difficult to treat without early recognition of their development and aggressive management. If the treatment is delayed, the progressive respiratory failure is almost uniformly fatal. Authors have experienced two cases of acute respiratory insufficiency following the blunt chest trauma, which were healed uneventfully. Literatures were briefly reviewed.

IgA nephropathy usually presents as asymptomatic microscopic hematuria or proteinuria or episodic gross hematuria after upper respiratory infection. It is an uncommon cause of end-stage renal failure in childhood. Pulmonary hemorrhage associated with IgA nephropathy is an unusual life-threatening manifestation in pediatric patients and is usually treated with aggressive immunosuppression. Pulmonary hemorrhage and renal failure usually occur concurrently, and the pulmonary manifestation is believed to be caused by the same immune process. We present the case of a 14-year-old patient with IgA nephropathy who had already progressed to end-stage renal failure in spite of immunosuppression and presented with pulmonary hemorrhage during oral prednisone treatment. His lung disease was comparable to diffuse alveolar hemorrhage and was successfully treated with plasmapheresis followed by oral prednisone. This case suggests that pulmonary hemorrhage may develop independently of renal manifestation, and that plasmapheresis should be considered as adjunctive therapy to immunosuppressive medication for treating IgA nephropathy with pulmonary hemorrhage.

A clinical evaluation was performed with a population of 49 patients of chest trauma, who were diagnosed to undergo ventilator therapy, and had gone through ventilator therapy at the Department of Thoracic and Cardiovascular Surgery, Kyungpook University Hospital. One of most common causes of chest trauma was vehicle accidents [77.5%] with the prevalent age group being their forties. The common findings were multiple rib fractures [89.8%], hemopneumothrax [81.6%], lung contusion [61.2%] and flail chest [44.9%]. Their common combined injuries were the orthopedics and neurosugical injuries [86.7%]. Complications caused by chest trauma were pneumonia, respiratory failure, atelectasis, barotrauma and empyema. Pulmonary infections were commonly associated with mechanical ventilation in the long term group and were best prevented by using bronchial hygiene therapy.The mortality rate was 5.8% of the total patients and that was 38.8% of the patients, who needed ventilator therapy. The causes of death were pneumonia, respiratory failure, acute renal failure and hypovolemic shock. Mechanical ventilation has an important place in the treatment of patients with severe chest trauma.

An eight-year-old, 28-kg male bull terrier who showed signs of lethargy and cough was referred for further evaluation of congestive heart failure. On presentation, physical examination revealed a systolic murmur at the left apex of the heart. Moreover, chest radiograph evaluation confirmed the mild alveolar and interstitial patterns in the caudal lung lobes and a grossly enlarged left atrium and left ventricle. Electrocardiography showed atrial fibrillation with a wide QRS complex, and transthoracic echocardiography revealed marked enlargement of the left atrium with abnormal morphology of the mitral valve. The thickened, hammer-like appearance and abnormal diastolic motion of the mitral valve leaflets were characterized by decreased leaflet separation and doming of the valve. The diagnosis was mitral stenosis with congestive heart failure and atrial fibrillation. The owner declined interventional valvuloplasty. Medical treatment included furosemide, pimobendan and diltiazem. Regular health check-ups have shown that vitality and clinical signs have improved considerably, and the dog have remained stable for 6 months after the presentation.

Background: Extracorporeal membrane oxygenation (ECMO) during severe acute respiratory failure helps to recover the pulmonary function. This study evaluated our experience with veno-venous ECMO in adult patients with acute respiratory failure. Methods: From January 2007 to July 2009, ECMO was used on 54 patients. Of these 54 patients, 7 were placed on veno-venous ECMO for acute respiratory failure. The indications of ECMO were based on the lung dysfunction measured as a $PaO_2/FiO_2$ ratio <100 mm Hg on $FiO_2$ of 1.0, or an arterial blood gas pH <7.25 due to hypercapnia despite the optimal treatment. $EBS^{(R)}$, $Bio-pump^{(R)}$, and Centrifugal Rotaflow $pump^{(R)}$ were used and all cannulations were performed percutaneously via both femoral veins. When the lung function was improved, an attempt was made to wean on ECMO at moderate ventilator settings followed by decannulation. Results: Five of the 7 patients were male and the mean age was $46.3{\pm}18.3$. The causes of acute respiratory failure were 3 cases of pneumonia, 2 near-drownings, 1 pulmonary hemorrhage due to acute hepatic failure and 1 mercury vapor poisoning. The mean support time of ECMO was $17.3{\pm}13.7$ days. Of the 7 patients implanted with ECMO, 5 patients (71%) were weaned off ECMO and 3 patients (43%) survived to hospital discharge after a mean 89.6 hospital days. Conclusion: The early use of ECMO for acute respiratory failure in adults due to any cause is a good therapeutic option for those unresponsive to the optimal conventional treatments.

Hyperhidrosis is the distressing condition of abnormal sweating which affects the palm, sole and axillary region. Transthoracic endoscopic sympathectomy is recommended as the treatment of choice for hyperhidrosis, especially when the upper limbs are affected. We experienced a case of accidental cauterization of right azygos vein in a healthy 23 year old male during endoscopic transthoracic sympathectomy. We changed the single lumen endotracheal tube to a double lumen tube which made it easier to perform the explo-thoracotomy and bleeder ligation under one lung ventilation. Crystalloid and colloid solutions, and packed RBC were loaded during explo-thoracotomy. Monitoring showed the signs indicating pulmonary edema. Pulmonary arterial catheterization revealed global heart failure. The patient was transfered to ICU for intensive management for heart failure. On the 4th postoperative day, pulmonary edema and heart failure were cured; and the patient was extubated. But in the evening of the same day ST-segment elevation and Q-wave were noted on ECG monitoring. On the 13th postoperative day coronary angiography was performed. This revealed left apex focal hypokinesia, patent coronary artery and accidental right coronary spasm, treated by vasodilator. On the 14 day, after surgery, he was discharged to return to work.

Bronchiolitis obliterans (BO), which is associated with graft-versus-host disease after allogenic hematopoietic stem cell transplantation, is a major obstacle to survival after bone marrow transplantation due to its gradual progress, eventually leading to respiratory failure. Pumpless extracorporeal interventional lung assist (iLA) is effective in treatment of reversible hypercapnic respiratory failure. In this paper, we present a 23-year-old female patient who underwent allogeneic peripheral blood stem cell transplantation (PBSCT) for acute lymphocytic leukemia. After 6 months, she complained of shortness of breath and was diagnosed with BO. Five months later, she developed an upper respiratory tract infection that worsened her BO and caused life-threatening hypercapnia. Since mechanical ventilation failed to eliminate $CO_2$ effectively, iLA was applied as rescue therapy. Her hypercapnia and respiratory acidosis showed significant improvement within a few hours, and she was successfully weaned off iLA after 12 days. This is the first case report of iLA application for temporarily aggravated hypercapnia of PBSCT-associated BO followed by successful weaning. This rescue therapy should be considered in ventilator-refractory reversible hypercapnia in BO patients.

Primary anaplastic large cell lymphoma (ALCL) of the lung is highly aggressive and quite rare. We report here a case of anaplastic lymphoma kinase-positive endobronchial ALCL, that was initially thought to be primary lung cancer. A 68-year-old woman presented with hemoptysis, dyspnea, and upper respiratory symptoms persisting since 1 month. The hemoptysis and and bronchial obstruction lead to respiratory failure, prompting emergency radiotherapy and steroid treatment based on the probable diagnosis of lung cancer, although a biopsy did not confirm malignancy. Following treatment, her symptoms resolved completely. Chest computed tomography scan performed 8 months later showed increased and enlarged intra-abdominal lymph nodes, suggesting lymphoma. At that time, a lymph node biopsy was recommended, but the patient refused and was lost to follow up. Sixteen months later, the patient revisited the emergency department, complaining of persistent abdominal pain since several months. A laparoscopic intra-abdominal lymph node biopsy confirmed a diagnosis of ALCL.
