Pediatric interstitial lung disease comprises a diverse group of rare conditions characterized by an infiltrative process, abnormal gas exchange, and restrictive lung disease. Although the disorder is similar to its adult counterpart, its course is complicated by the continued need for lung growth and differentiation in infants and children. ⋯ Clinicians continue to define the various types of interstitial lung disease and to evaluate the roles of bronchoalveolar lavage, radiography, and biopsy in diagnosis. Together, investigators are working toward the development of specific, targeted therapy that will reduce the significant morbidity and mortality seen in pediatric interstitial lung disease.

Case Reports
Lung adenocarcinoma in lymphocytic interstitial pneumonitis associated with primary Sjögren's syndrome.
We experienced a rare case of lung adenocarcinoma associated with lymphocytic interstitial pneumonitis caused by primary Sjögren's syndrome. A 78-year-old woman was referred to our hospital because of progressive sicca syndrome and nodular opacities in the right lower lobe on chest radiograph. This patient was diagnosed as primary Sjögren's syndrome by a labial gland biopsy and classical clinical features including xerophthalmia, xerostomia and immunoserological findings. ⋯ There was no evidence of malignant lymphoma in the lymph nodes or resected lung tissue. Pulmonary involvement of Sjögren's syndrome is now regarded both clinically and histopathologically as a wide spectrum of lymphoproliferative disorders ranging from benign to malignant. However, lung cancer associated with primary Sjögren's syndrome, as in our case, has apparently not been reported previously.

To characterize the computed tomographic (CT) findings of acute interstitial pneumonia and to correlate the pattern and the extent of abnormalities with the time between symptom onset and CT. ⋯ A combination of ground-glass attenuation, airspace consolidation, traction bronchiectasis, and architectural distortion is seen in the majority of patients with acute interstitial pneumonia. The extent of ground-glass attenuation and traction bronchiectasis increases with disease duration.

We report a case of drug-induced pneumonitis associated with the herbal medications Sho-saiko-to and Ouren-gedoku-to. A 62-year-old man experienced fever and dry cough after using Ouren-gedoku-to for 2 months. He was admitted to our hospital because a subsequent 5-day course of Sho-saiko-to for suspected bronchitis aggravated these symptoms and caused exertional dyspnea. ⋯ While drug-induced lymphocyte stimulation tests gave negative results, challenge tests for Ouren-gedoku-to and Sho-saiko-to were both positive. A diagnosis of drug-induced pneumonitis was made. Our findings suggested the involvement of Ougon, the only common ingredient in the two medications.

A 72 year old female with rheumatoid arthritis was treated with methotrexate for nine months. Four days before admission she complained of dyspnea NYHA III. Chest-X-ray revealed diffuse interstitial pneumopathy. ⋯ Methotrexate-induced pneumonitis remained the most probable diagnosis. We halted methotrexate and initiated therapy with glucocorticoids. This treatment led to rapid clinical improvement and complete resolution of radiological changes.
