Atelocollagen have been used recently in skin and other soft tissue defect regions more than silicone fluid because of the low incidence of an immune reaction and complications. Several cases of acute pneumonitis after a subcutaneous injection of silicone have been reported. The symptoms were dyspnea, fever, chest pain and hemoptysis. Previous reports have explained the pathophysiology of acute pneumonitis to a pulmonary microembolism and cellular inflammation. We experienced two cases of an acute interstitial pneumonitis and pulmonary hemorrhage after a subcutaneous injection of atelocollagen. They were all healthy young women and complained of dyspnea, fever and blood tinged sputum. The chest radiography and computerized tomography showed a bilateral ground glass opacity in both lung fields. One case recovered completely with conservative treatment but the clinical course of the other case was aggravated to the degree that invasive positive pressure ventilation therapy was required. We report a rare case of a diffuse pulmonary alveolar hemorrhage and an interstitial pneumonitis after the subcutaneous injection of atelocollagen for cosmetic purposes.

So far more than 350 drugs have been reported to be the cause for lung injury and the incidence tends to increase. Although infiltrative lung disease is the most common pattern of drug-induced lung injury, it can appear in the form of alveolar changes, vasculitis and other injury. Herbal medicine also has been known as a cause for interstitial pneumonitis, but it is difficult to identify the key herbal medicine because of the complex components of the contents. Till date, there is no report of pneumonitis caused by golden thread. Here we report a case of a 54-year-old male who developed interstitial pneumonitis with acute liver injury caused by herbal medicine made from golden thread.

Leflunomide, a disease-modifying antirheumatic drug (DMARD) for the treatment of rheumatoid arthritis has been available in Korea since 2003. Leflunomide-associated interstitial pneumonitis has been appearing recently. A 25-year-old woman with a 12-month history of seronegative rheumatoid arthritis (RA) presented with acute respiratory insufficiency. She developed fever, dyspnea, and non-productive cough. Her medication history included methotrexate (15 mg/week. commencing 1 year prior) and leflunomide (20 mg/day, no loading dose, commencing 4 months prior). She was diagnosed with leflunomide-associated interstitial pneumonitis based on history, physical examination, laboratory and radiologic findings. She recovered quickly after leflunomide was withdrawn and steroids and cholestyramine were initiated quickly. We report a case of leflunomide-associated interstitial pneumonitis treated successfully with intravenous high-dose steroid and cholestyramine.

Ulcerative colitis (UC) is a chronic idiopathic inflammatory bowel disease. Mesalizine for the first-line therapy of UC has adverse effects include pancreatitis, pneumonia and pericarditis. UC complicated by two coexisting conditions, however, is very rare. Moreover, drug-related pulmonary toxicity is particularly rare. An 11-year-old male patient was hospitalized for recurring upper abdominal pain after meals with vomiting, hematochezia and exertional dyspnea developing at 2 weeks of mesalizine therapy for UC. The serum level of lipase was elevated. Chest X-ray and thorax computed tomography showed interstitial pneumonitis. Mesalizine was discontinued and steroid therapy was initiated. Five days after admission, symptoms were resolved and mesalizine was resumed after a drop in amylase and lipase level. Symptoms returned the following day, however, accompanied by increased the serum levels of amylase and lipase. Mesalizine was discontinued again and recurring symptoms rapidly improved.

Background: In Korea, a healthy 36-year-old man developed acute interstitial pneumonitis soon after inhaling a waterproofing spray which he had applied at home to his outdoor jacket. Objectives: The objectives of this study were to review cases of varying degrees of respiratory toxicity and poisoning in connection with the use of waterproofing spray and summarize major reasons for cases of poisoning. Methods: We searched articles reporting on a combination of a waterproofing agent and/or respiratory symptoms, including acute respiratory syndrome, lung injury, pneumonia, pulmonary toxicity, and respiratory disease. Results: We reviewed a number of cases of varying degrees of respiratory toxicity and poisoning resulting from inhalation of waterproofing spray containing fluorocarbon co-polymer, solvents and propellants reported in a variety of countries. The literature searches concluded that among the ingredients of waterproofing agents, fluorinated polymer may cause acute respiratory health effects. Conclusion: Environmental policy should be implemented in order to prevent consumers from using household and industrial products including waterproofing agents. In addition, a national surveillance system should be created to collect cases of poisoning caused by the use of consumer products.

A 16 years old girl with systemic lupus erythematosus had a high fever for 20 days. Skin and renal biopsy showed diffuse granular deposits (IgG, IgM, $C_3$, $C_{1q}$ at dermo-epideral junction and IgG, IgA, IgM, $C_3$, $C_{1q}$, fibrinogen in the renal mesangium and segmentally along the capillary walls) which were compatable with systemic lupus erythematosus. The chest X-ray revealed patchy mottled densities in whole lung field when she complained more dyspnea at 9th hospital days. Even with the parenteral administration of broad-spectrum antibiotics, the symptoms of high fever, cough, tachydyspnea and hypoxia were continued. At 24th hospital day, the clinical course was rapidly deteriorated after sudden loss of consciousness with focal seizure which suggested CNS involvement during hydrocortisone administration for 10 days. She died of respiratory failure despite the mechanical ventilatory support with PEEP. The limited necropsy showed interstitial pneumonia, alveolar hemorrhage and occlusive necrotizing vasculitis of acute lupus pneumonitis.

Methotrexate is commonly used in rheumatoid arthritis as an anti-inflammatory agent, but treatment with methotrexate can lead to severe side effects, especially pulmonary complication. Interstitial pneumonitis is one of the most important pulmonary adverse effects of methotrexate and most patient present with a subacute febrile illness and peripheral eosinophilia is seen in about a half of patients. Almost all patients have abnormal chest roentgenograms and bibasilar interstitial infiltration with alveolar pulmonary consolidations is the most characteristic finding. Interstitial inflammation with mononuclear cell infiltration is a characteristic pathologic feature and findings that suggest acute hypersensitivity pneumonitis, such as bronchiolitis, granuloma formation with giant cells, and infiltration with eosinophils are often present. Methotrexate-induced pneumonitis is a potentially life threatening and unpredictable complication but it is difficult to make a definite diagnosis in the absence of high index of clinical suspicion. Early recognition and appropriate management may avoid the serious outcome. Herein we report a case of methotrexate-induced pneumonitis in a patient with rheumatoid arthritis.

Interstitial pneumonitis may be the presenting manifestation of polymyositis-dermatomyositis (PM-DM), or may occur later in the evolution of disease. The clinical picture is characterized by non-productive cough, dyspnea and hypoxemia. The chest radiograph demonstrates interstitial infiltrates with predilection for the lung bases, often with an alveolar pattern in addition. We experienced a case of polymyositis associated with diffuse alveolar damage(DAD) that was proven in open lung biopsy. The patient was a 52 year-old woman who was presented with 6 months' duration of generalized ache, edema on ankle and wrist, non-productive cough and mild dyspnea. She had typical symptoms and physical findings of interstitial pneuminitis, and elevated muscle enzyme levels in serum with characteristic histologic findings of myositis on muscle biopsy. She also had typical interstitial lung disease pattern on high resolution CT and restrictive pattern on pulmonary function tests. The findings of open lung biopsy was compatible with diffuse alveolar damage(DAD). She failed to respond to the therapeutic trials with corticosteroid and cyclophosphamide, and finally expired due to acute respiratory distress syndrome.

Amiodarone is widely used to control fatal arrhythmia. However, amiodarone therapy is associated with a relatively high incidence of pulmonary toxicity, up to 5 to 10%. Typical symptoms are nonspecific and often manifest as nonproductive cough, dyspnea and interstitial infiltrates in patients with acute pneumonitis or chronic fibrosis. However, hemoptysis is a very rare symptom of amiodarone pulmonary toxicity. We report a case of amiodarone pulmonary toxicity, who presented with hemoptysis and was successfully treated with the cessation of amiodarone, with review of the relevant literature.

Background : Methotrexate (MTX) has been used to treat a wide range of malignant and benign diseases including osteosarcoma, advanced stage non-Hodgkin's lymphoma, psoriasis, severe rheumatoid arthritis, sarcoidosis, and Wegener's granulomatosis. MTX-induced lung injury occurs in up to 10% of treated patients. Although both acute and chronic presentations have been described, typical manifestation of MTX-induced lung injury is subacute with symptoms usually developing within several months after starting therapy. Nonspecific interstitial pneumonia (NSIP) is the most common histopathologic manifestation of MTX-induced lung disease, while bronchiolitis obliterans organizing pneumonia (BOOP) and diffuse alveolar damage (DAD) are less common. Granuloma formation is reported in 34.7%. In Korea, Two reports of MTX pneumonitis have been published. The one presented with NSIP and the other with DAD. We recently experienced a case of MTX pneumonitis with presentation of hypersensitivity pneumonitis.
