Pulmonary Edema Occurring after Nitric Acid Exposure.

Nitric acid (HNO) is a strong acid and oxidizing agent used for various applications including production of ammonium nitrate in the fertilizer industry. Nitrogen oxides formed when nitric acid interacts with the environment have been implicated in inhalation injuries. This describes a case of a 49-year-old male who presented to the emergency department complaining of an acute onset of shortness of breath approximately 12 hours after being exposed to nitric acid fumes.

Lionfish envenomation.

Lionfish (Pterois volitans) are venomous fish most often found as aquarium pets throughout the United States. Lionfish envenomations frequently occur on the upper extremities, with pain as the predominant symptom. Immersing the injured part in warm (45 degrees C) water is considered the first and foremost important treatment as it is reported to relieve pain and inactivate the venom.
