A Case of Pneumothorax Secondary to Marijuana Use Disorder.

In recent decades, the general tendency has switched from the use of tobacco products to the inhalation of marijuana with or without the addition of tobacco. The majority of existing research on marijuana use focuses on its euphoric effects. Pneumothorax, pneumomediastinum, and subcutaneous emphysema are infrequently described in the medical literature in association with cannabis use. It is a diagnostic and therapeutic challenge because of its infrequency of occurrence. We see a huge diversity of multisystem involvement linked with marijuana smoking, and physicians should be aware of this uncommon clinical presentation, which might be observed more often because of the recent upsurge in its consumption. We describe a case of a 20-year-old male with a chronic history of marijuana use disorder who was found to have non-tension type pneumothorax, pneumomediastinum, and subcutaneous emphysema on chest imaging. The patient was managed conservatively and did not require any surgical intervention.

Two-dimensional transthoracic echocardiographic demonstration of reduction in fibrin content in purulent pericarditis following intrapericardial fibrinolytic agent administration.

We describe an adult patient who presented with purulent pericarditis (PP) in whom two-dimensional transthoracic echocardiography demonstrated a marked decrease in the area of the right ventricular (RV) wall together with the overlying fibrin following intrapericardial administration of a fibrinolytic agent. Documentation of this decrease by measurements performed and illustrated on two-dimensional images has not been reported previously in an adult patient with PP, to the best of our knowledge.
