Typical episodes of transient neurapraxia only last a few seconds and symptoms dissipate entirely. Though the severity of the injury can range, transient neurapraxia does not lead to permanent paralysis of the affected muscles. Subsequent spinal cord injury after an episode of cervical cord neurapraxia has not been observed. However, athletes who experience an episode of transient cervical neurapraxia face an approximately 50% chance of a repeat episode if they continue to participate in collision sports. American football
Cervical cord neurapraxia among American football players is commonly observed in athletes playing positions involving high-speed collisions and open-field tackling. Cases of neurapraxia in the National Football League were first described in 1986 by Joseph S. Torg, M.D., founder of the National Football Head and Neck Injury Registry (established in 1975). As a result of Dr. Torgs findings the NFL as well as other levels of American football have outlawed the act of spearing, or the lowering of the head and hitting an opponent with the crown of the helmet. The cervical spine cannot properly absorb the force of a collision when the head is even slightly lowered as is the case in spearing. In addition to outlawing acts such as spearing, prevention of neurapraxia on the football field relies on instruction and reinforcement of proper tackling technique by coaches and trainers. In popular culture
In M*A*S*H Season 4 Episode one, Benjamin "Hawkeye" Pierce claims that Walter "Radar" OReilly has neurapraxia as an excuse for driving past a military checkpoint.
Infants who have severe anemia and/or thrombocytopenia can be given blood products; for those who have cardiac failure, diuretics and digoxin are often given. To stop further growth and to speed regression of lesions in infants with more significant clinical sequelae, treatment with corticosteroids or interferon-α-2a is administered. To slow the growth of tumors that are rapidly enlarging, chemotherapy and radiation therapy have been used. Surgical resection, partial hepatectomy, and embolization of afferent vessels should be considered for severe cases. Treatment
Treatment is varied and depends on the site and extent of tumor involvement, sites of metastasis, and specific individual factors. Surgical resection, radiotherapy, and chemotherapy have all been used to treat these masses, although studies on survival have yet to be conducted to delineate various treatment regimens. Kaposiform hemangioendothelioma might respond to chemotherapy or antiangiogenic therapies. Recently propanolol and steroids have been shown to be very effective in kaposiform hemangioendothelioma.
