The epineurium of the nerve is contiguous with the dura mater, providing extra support to the nerve.Brachial plexus lesions typically result from excessive stretching; from rupture injury where the nerve is torn but not at the spinal cord; or from avulsion injuries, where the nerve is torn from its attachment at the spinal cord. A bony fragment, pseudoaneurysm, hematoma, or callus formation of fractured clavicle can also put pressure on the injured nerve, disrupting innervation of the muscles. A trauma directly on the shoulder and neck region can crush the brachial plexus between the clavicle and the first rib.Although injuries can occur at any time, many brachial plexus injuries happen during birth: the babys shoulders may become impacted during the birth process causing the brachial plexus nerves to stretch or tear. Obstetric injuries may occur from mechanical injury involving shoulder dystocia during difficult childbirth, the most common of which result from injurious stretching of the childs brachial plexus during birth, most often during vaginal birth, but occasionally Caesarean section. The excessive stretch results in incomplete sensory and/or motor function of the injured nerve.Injuries to the brachial plexus result from excessive stretching or tearing of the C5-T1 nerve fibers. These injuries can be located in front of or behind the clavicle, nerve disruptions, or root avulsions from the spinal cord. These injuries are diagnosed based on clinical exams, axon reflex testing, and electrophysiological testing. Brachial plexus injuries require quick treatment in order for the patient to make a full functional recovery (Tung, 2003).
In one of the alternative medical uses of honey bee products, apitherapy, bee venom has been used to treat arthritis and other painful conditions. All currently available evidence supporting this practice is either anecdotal, animal studies, or preliminary evidence, most of which has poor methodology. Apitherapy is not currently accepted as a viable medical treatment for any condition or disease; the risk of allergic reaction and anaphylaxis outweighs any benefits. According to the American Cancer Society, there is no scientific evidence that apitherapy or bee venom therapy can treat or change the course of cancer or any other disease. Clinical trials have shown that apitherapy is ineffective in treating multiple sclerosis or any other disease, and can exacerbate multiple sclerosis symptoms. Treatment
The first step in treatment following a honey bee sting is removal of the stinger itself. The stinger should be removed as quickly as possible without regard to method: a study has shown the amount of venom delivered does not differ whether the sting is pinched or scraped off and even a delay of a few seconds leads to more venom being injected. Once the stinger is removed, pain and swelling should be reduced with a cold compress. A topical anesthetic containing benzocaine will relieve pain quickly and menthol is an effective anti-itch treatment. Itching can also be relieved by antihistamine or by a topical steroid cream.Many traditional remedies have been suggested for bee stings.
