An 85-year-old woman with antibiotics-resistant pneumonia after surgery for metastatic brain tumor from lung cancer was consulted to our department. Chest CT showed diffuse GGO bilaterally. BALF showed elevated ratios of lymphocytes and CD4/CD8. Tests for bacteria, mycobacteria, and fungi were negative. She improved following levetiracetam discontinuance and systemic corticosteroid administration, and we diagnosed levetiracetam-induced lung injury. Although levetiracetam is widely used, few reports of levetiracetam-induced pneumonia exist. Changes in chest images may occur after levetiracetam administration if patients have multiple risk factors for development of drug-induced interstitial lung disease. Bronchoscopy is useful for differential diagnosis if new lung lesions appear after starting levetiracetam.

Protective effects of oil, thymoquinone and dexamethasone on bleomycin-induced lung fibrosis in rats.

Pulmonary fibrosis (PF) is a chronic interstitial lung disease with a progressive damage to the air sacs and deposition of collagen fibers in the lung tissue. The study aimed to explore the effects of oil (NSO) or thymoquinone (TQ), alone or in combination with dexamethasone (DEX), on the development of bleomycin (BLM)-induced PF. Forty-two male rats were divided into seven groups: Control (CTRL); BLM, received a single dose of BLM on day 0, intratracheally; all remaining groups received BLM, as well.

Initial imaging in February 2023 showed signs of a renal cell carcinoma and possible lung metastases. A CT-guided biopsy and histopathological analysis ruled out malignancy and confirmed a benign inflammatory pseudotumor.

Approximately 30-50% of SSc patients develop interstitial lung disease (SSc-ILD), with 30-35% of related deaths attributed to it. Even though men are less likely to develop systemic sclerosis, they have a higher incidence of SSc-ILD than women, and they tend to develop it at a younger age with a higher mortality rate.

Background: Pulmonary rehabilitation (PR) is a beneficial intervention for people with interstitial lung disease (ILD), however the effect of PR on survival is unclear. This study compared the survival outcomes in people with ILD who were allocated to PR versus those who were allocated to control in two published randomised controlled trials (RCTs).
Research Question: Does participation in PR impact survival among people with ILD?
Study Design And Methods: The combined data from the two previous RCTs of PR in ILD were included.
