Cerebral Air Embolism Triggered by Infection of a Pulmonary Cyst in the Context of Air Travel: A Case Report.

Cerebral air embolism (CAE) is a rare and potentially fatal event. While most cases result from iatrogenic causes, such as central venous catheterization, pulmonary sources, especially infected cysts, are scarcely reported. We describe a case of a previously healthy 61‑year‑old man who lost consciousness immediately after a flight.

Alternative Gene Expression by TOLLIP Variant Is Associated With Lung Function in Chronic Hypersensitivity Pneumonitis.

Background: Chronic hypersensitivity pneumonitis (CHP) is a heterogeneous fibrotic interstitial pneumonia resulting from the immune response of susceptible individuals to inhaled antigens. Genetic predispositions have been suggested in CHP; however, the link between susceptibility genes and fibrotic progression has not been elucidated fully. Recent data suggest that variants in Toll-interacting protein gene (TOLLIP) are associated with lung diseases.

[A Case of Pulmonary Enteric Adenocarcinoma with Soleus Muscle Metastasis].

Pulmonary enteric adenocarcinoma is a unique pulmonary adenocarcinoma subtype and has histopathological findings that are similar to those of colorectal adenocarcinoma. A man in his 50s visited our hospital because of discomfort in his right lower leg for the last 9 months. Imaging studies revealed a mass in his right soleus muscle, and needle biopsy was performed.
