Catamenial pneumothorax is a spontaneous pneumothorax that recurs during menstruation, within 72 hours before or after the onset of a cycle. [1] It usually involves the right side of the chest and right lung, and is associated with thoracic endometriosis . [ 2 ]
Small fiber peripheral neuropathy is a type of peripheral neuropathy that occurs from damage to the small unmyelinated and myelinated peripheral nerve fibers. These fibers, categorized as C fibers and small Aδ fibers , are present in skin , peripheral nerves , and organs. [ 1 ]
No treatment is known to speed the healing of a pulmonary contusion; the main care is supportive. [39] Attempts are made to discover injuries accompanying the contusion, [ 20 ] to prevent additional injury, and to provide supportive care while waiting for the contusion to heal. [ 39 ]
Peripheral neuropathy may be classified according to the number and distribution of nerves affected (mononeuropathy, mononeuritis multiplex, or polyneuropathy), the type of nerve fiber predominantly affected (motor, sensory, autonomic), or the process affecting the nerves; e.g., inflammation (), compression (compression neuropathy), chemotherapy (chemotherapy-induced peripheral neuropathy).
Acute motor axonal neuropathy (AMAN) is a variant of Guillain–Barré syndrome. It is characterized by acute paralysis and loss of reflexes without sensory loss. Pathologically , there is motor axonal degeneration with antibody-mediated attacks of motor nerves and nodes of Ranvier .
Therefore, pneumothorax is usually more of a problem than hemothorax. [8] A pneumothorax may form or be turned into a tension pneumothorax by mechanical ventilation, which may force air out of the tear in the lung. [12] The laceration may also close up by itself, which can cause it to trap blood and potentially form a cyst or hematoma. [8]
Spontaneous pneumothorax is, as in humans, classified as primary or secondary, while traumatic pneumothorax is divided into open and closed (with or without chest wall damage). [65] The diagnosis may be apparent to the veterinary physician because the animal exhibits difficulty breathing in, or has shallow breathing.
Subcutaneous emphysema is not typically dangerous in and of itself, however it can be a symptom of very dangerous underlying conditions, such as pneumothorax. [7] Although the underlying conditions require treatment, subcutaneous emphysema usually does not; small amounts of air are reabsorbed by the body.
