Pneumatosis intestinalis or spontaneous pneumomediastinum are rarely associated with nonspecific interstitial pneumonia (NSIP). However, the development of both conditions in the same patient simultaneously has not been reported previously. A 56-year-old man with NSIP developed spontaneous pneumomediastinum accompanied by subcutaneous emphysema and pneumatosis intestinalis after the treatment with intravenous high dose steroid. The development of spontaneous pneumomediastinum, subcutaneous emphysema and pneumatosis intestinalis in this patient was possibly due to the factors such as NSIP, high dose steroid therapy and subclinical dermatomyositis. Treatment with corticosteroid and cyclosporin gradually improved his exacerbated NSIP and pneumomediastinum, subcutaneous emphysema, pneumatosis intestinalis.

Interstitial lung disease refers to a group of pulmonary disorders characterized by inflammation of the interstitium, derangements and loss of alveolar capillary units leading to disruption of alveolar gas exchange, which induces symptoms of restrictive lung disease. Cases of interstitial pneumonia in children are uncommon and mostly have unknown causes. We have experienced an 8-year old boy who had symptoms of cyanosis, dry cough, dyspnea and abrupt weight loss. He had not been exposed to organic dusts, allergens or any other systemic disease infections. Chest radiology showed diffuse ground glass opacity in both lung fields. High resolution computed tomography(HRCT) showed multiple small patchy areas of consolidation with an underlying ground glass appearance in both lungs. The pathologic findings of lung biopsy tissue showed patchy areas of interstitial fibrosis, alveolar obliteration and nodular fibrotic areas, strongly suggesting interstitial pneumonia. No specific finding of viral inclusion or any other evidence of infection was found under electromicroscopy. We used peak flow meters to compare functional improvement. Forced expiratory volume in one second ($FEV_1$) was decreased to 25 percent of predicted value. The boy was given treatment with prednisone and showed improvements in HRCT findings after two months. He was able to tolerate easy exercise in school and showed clinical improvements after one year of follow up.

Background: Most studies of Mycoplasma pneumonia involve a group of admitted patients in hospital, usually with major medical illness. So we investigated the epidemiologic and radiologic features during the course of outbreak of pneumonia in Chunnam coastal area. Methods: We retrospectively studied the epidemiologic and clinical feature of 105 patients with serologically proven Mycoplasma pneumonia treated at Kwang-Yang Hospital during a epidemic period of Jun.1993 to Dec.1993. All cases of pneumonia developed in this period were also reviewed and compared with serologically proven group. Results: 1) There were 63 males and 42 females. 2) More than half(57%) of cases belonged to 5-9 years of age group, and mean age was 6.5 years old. Mean age was steadily decreased as prevalence of Mycoplasma pneumonia had been subsided. 3) A major determinant of the outbreak seemed to be the population density rather than the population size. 4) The common radiologic features were interstitial in type, and 67 cases was restricted to one lobe. Lobar types are more common in late childhood, and interstitial or diffuse types in early childhood. Conclusion: These epidemiologic and radiographic characteristics would contribute to the diagnosis of Mycoplasma pneumonia.

Systemic lupus erythematosus frequently has thoracic involvement among connective tissue diseases. One of the pleuropulmonary manifestations is diffuse interstitial lung disease including nonspecific interstitial pneumonia(NSIP). NSIP is a newly classified disease among interstitial lung diseases. Systemic lupus erythematosus has a better prognosis than usual interstitial peumonia(UIP) and responds well to steroids. In this report, a 34 year-old woman who complained of a dry cough, and exertional dyspnea for 2 months is described. The chest X-ray showed fine reticular opacities and a mild honeycomb appearance in both basal lungs. High resolution computed tomography(HRCT) showed bilateral patchy areas of ground-glass attenuation and a mild honeycomb appearance in the subpleural of both the lower and the middle portion of the lung fields. An open lung biopsy showed prominent lymphocytic interstitial inflammation and fibrosis with small areas with a honeycomb appearance. This case was diagnosed as NSIP associated with systemic lupus erythematosus and was managed with oral steroids. Here we report a case of nonspecific interstitial pneumonia associated with systemic lupus erythematosus confirmed by HRCT and an open lung biopsy with a review of the relevant literature.

Gefitinib is a novel drug used to treat advanced non-small cell lung cancer. However, drug-related interstitial pneumonia is a major life-threatening side effect, which has a worldwide prevalence of 0.3-0.4%. In Japan, the prevalence is high as 3-4% but the actual frequency in Korea has not been officially assessed. We report two cases of gefitinib-induced interstitial lung disease during the treatment of non-small cell lung cancer. High-resolution computerized tomography (HRCT) of one case showed nonspecific ground glass opacity and the chest x-ray of another case showed diffuse bilateral ground glass opacity. The former patient showed a rapid good response to corticosteroid treatment whereas the latter died despite receiving aggressive treatment with high dose corticosteroid and empirical antibiotics.

Background: Open lung biopsy is used for diagnosis of diffuse infiltrative lung diseases (DILD), but it is invasive and relatively expensive procedure. Fluoroscopy-guided cutting needle lung biopsy (FCNLB) has merits of avoidance of admission and rapid diagnosis. But diagnostic accuracy and safety were not well known in the diagnosis of DILD. Methods: We included 52 patients (37 men, 15 women) having DILD on HRCT with dyspnea, except the patients who could be confidently diagnosed with clinical and HRCT findings. FCNLB was performed using 16G Ace cut needle (length 1.5 cm, diameter 2 mm) at the area of most active lesion on HRCT. Final diagnoses were made by the consensus. Results: The mean interval between the HRCT and FCNLB was 4.5 days. Most cases were performed one biopsy during 5~10 minutes. Specific diagnosis was obtained in 43 of 52 biopsies (83%). The most common diagnosis was nonspecific interstitial pneumonia (11 cases) and followed by cryptogenic organizing pneumonia (7 cases), diffuse alveolar hemorrhage and usual interstitial pneumonia (5 cases in each), hypersensitivity pneumonitis (3 cases), tuberculosis and drug induced interstitial pneumonitis (2 cases in each), the others are in one respectively. Mild complication was developed in 9 patients (8 pneumothorax, 1 hemoptysis). Most of complications were regressed without treatment except one case with chest tube insertion for pneumothorax. Conclusion: Fluoroscopy-guided 16 G cutting needle lung biopsy was an useful method for the diagnosis of DILD.

In the average adult with a normal immune state, Epstein-Barr virus pneumonia is very rare, especially in the form of interstitial lung disease. According to recent studies, the Epstein-Barr virus is also associated with lymphocytic interstitial pneumonia, AIDS and Langerhans cell histiocytosis, but not with sarcoidosis. BOOP is caused by lung injury due to an infection or drug intoxication, and is related to connective tissue disease or bone marrow transplantation, but is sometimes idiopathic. We experienced a patient with symptoms and signs of interstitial lung disease, with confirmed BOOP and EBV ingection from an open lung biopsy and serologic examination, respectively Herein, this case is reported, with a review of the literature.

From September 1994 to October 1995, we are reporting clinical results of 67 patients whom underwent video-assisted trio rabic surgery(VATS). 1. They were diagnosed as spontaneous pneumothorax In )5, diffuse interstitial lung disease in 9, empyema in 7, hemothorax in 5, malignant pleural effusion in 3, hyperhidrosis in 3, foreign body in chest cavity in 2, mesothelioma in 1, miliary tuberculosis in 1 and organizing pneumonia in 12. In pneumothorax, bullectomy in 33 and open bellectoiny in 2 due to pleural adhesion was done Hemostasis in 5, irrigation in 7, foreign body removal in 2, talcum powder insufrlation in 3, sympathectomy 3 as done. Thoracoscopic biopsy watt done In 12 3. For pneumothorax, operation was indicated as recurrent pneumothorax in 18, persistent air leak in 12, visible bullae In chest X-ray in 5. 4 Thoracoscopic biopsy was done in 12. They were interstitial pulmonary fibrosis in 9, miliary tuberculosis in 1, mesothelioma in 1, and organizing pneumonia in 1 .Among interstitial pulmonary fibrosis, usual interstitial pneumonia were 2 and diffuse interstitial pneumonia were 7. 5. Wo complication was found in 6) patients among 67 patients. The complication was found in 4 patients (2 persistent air leak, 2 contralateral lung atelectasis). We concluded that VATS was safe and beneficial in reducing postoperative complication and the role of thoracic surgery will increase markefdly.

Lymphocytic interstitial pneumonia (LIP) is a rare disorder characterized by a diffuse infiltration of the alveolar space, interstitium by lymphocytes, plasma cells, and reticuloendothelial cells. Although its etiology is unknown, LIP has been associated with autoimmune disorders and with viral infections. Because it's clinical and radiographic features are nonspecific, a confirmatory diagnosis is performed by open lung biopsy. A 59-year-old female presented dry cough, which had been present for 1 month. On initial findings of multifocal consolidation at the right middle lobe on both lower lobes in chest radiography, the first diagnosis of cryptogenic organizing pneumonia was suggested. On open lung biopsy, LIP was diagnosed. The patient had no autoimmune disease, viral infection or monoclonal gammopathy. After 3 months of corticosteroid treatment, the patient experienced improved symptoms, reduced abnormalities on chest radiography, and improved pulmonary function testing.
