A carbon monoxide poisoning case due to lung diffusion test.

Carbon monoxide (CO) poisoning occurs due to CO gas which is produced by the incomplete combustion of hydrocarbons. Several causes of CO poisoning have been defined in the literature. The most frequent causes are defective heaters, fires and exposure to exhaust gas in closed areas. The lung diffusion test is a method used to detect alveolar membrane diffusion capacity. The standart gas used in the diffusion test is CO. The case is here presented of a patient who was poisoned by CO during a DLCO test. To the best of our knowledge, this is the first case report defining CO poisoning during a DLCO test and treated at the Emergency Department.

Preventable Diving-related Ocular Barotrauma: A Case Report.

The mystical beauty of the subaquatic world is undoubtedly attractive, and many techniques and forms of equipment have been developed in the last few decades to allow us to explore the underwater world. A swimmer or diver needs swimming goggles or a diving mask to have clear vision because of the refraction problem between the eye and the water interface. Although these items are effective for clear vision, they can result in "ocular or facial barotrauma of descent" during diving. It is possible to prevent these types of barotrauma with correct techniques and precautions, thus enabling the continuation of recreational diving without recurrence. In this paper, we report a case of subconjunctival hemorrhage caused by breath-hold diving and discuss the causes of ocular barotrauma of descent and preventive measures.
