Thus, patients nal cortex (a process mediated by adrenocorticotropic hormone [ACTH]), epineph- with diabetes mellitus may require higher rine from the adrenal medulla, and both insulin and glucagon from the pancreas. Although insulin is elevated during sepsis, the tissues exhibit an insulin resistance that is similar to that of the non–insulin-dependent diabetes mellitus patient, possi- bly resulting from the elevated levels of the insulin counterregulatory hormones (glucocorticoids, epinephrine, and glucagon). Changes in the rate of acute phase protein synthesis are mediated, at least in part, by effects of TNF, IL-1, and IL-6 on the synthesis of groups of proteins in the liver.

Acute dislocations should be reduced and the position causing the dislocation avoided purchase propecia 1 mg amex, which may require the use of a sling but needs to be individualized to each child propecia 5 mg lowest price. Parents and therapists need to be advised to avoid moving the arm into the position where the insta- bility occurs. Caretakers need to be advised to avoid lifting the children by holding the arms and definitely never lift them by pulling the arms into the extended and flexed overhead position. If recurrent dislocations get worse and do not slowly resolve, which almost always happens in childhood and adolescence, surgical reconstruction should be considered using standard shoulder stabilization procedures. If reconstruction fails or if the joint has severe degenerative arthritis, fusion of the shoulder joint is a good option. Occasionally, athetoid or dystonic patients will have an unstable shoul- der. An unstable shoulder is an extremely difficult problem to treat because standard soft-tissue repairs tend to stretch out when patients continue to posture the shoulder in an unstable position. Careful positioning of the shoulder, trying to avoid surgical treatment, is first attempted. Shoulder fu- sion may be required in resistant cases. We have had one dystonic patient whose shoulder became increasingly unstable as her scoliosis progressed. After correction of her spinal curvature with a spine fusion, her shoulder re- duced and became stable. Elbow and Forearm Elbow Flexion Contracture The elbow flexors have a significant mechanical advantage over the elbow extensors; therefore, when severe spasticity occurs, the flexors tend to shorten, which causes an elbow flexion contracture. The biceps is a two-joint muscle and is the primary cause of the contracture. The brachialis and brachio- radialis are one-joint muscles that also develop contractures, especially with severe and long-standing contractures. Natural History Fixed contractures tend to develop in late childhood and adolescence. For individuals with severe quadriplegia, the flexion contracture may become so severe that bathing and keeping the elbow flexion crease clean becomes dif- ficult. In individuals with hemiplegia, the position of the flexed elbow causes a significant cosmetic concern. Usually, by young adulthood, the contracture is fixed and not progressive. Treatment In young childhood and middle childhood the use of extension splinting may be helpful, although there is no good documentation. Injection of the elbow flexors with botulinum toxin has been reported, but none of these reports 400 Cerebral Palsy Management suggest that any significant lasting benefits occurred. As the contracture becomes very severe and causes problems with hygiene, a surgical release of the elbow flexors is indicated. In individuals with severe quadriplegia and severe contractures, the release should include a complete transection of the distal biceps, brachialis, and brachioradialis. This level of release usually allows el- bow extension to be between approximately 60° and 90° of flexion, which is enough to allow for bathing and keeping the elbow clean. In individuals with hemiplegia, the release of the flexion contracture is indicated because of a cosmetic concern of the elbow always being in a flexed position. If individuals are very functional with their arms and the contrac- tures are mainly dynamic, a Z-lengthening of the biceps tendon is indicated. If the arms are less functional or a fixed contracture of 10° to 20° is present, a complete release of the biceps tendon is indicated. For children with more severe positioning, especially if their arms are held to almost 90° during am- bulation, a myofascial lengthening of the brachialis is added. Elbow flexor lengthening during late childhood and adolescence does seem to provide a permanent improvement in elbow extension. In rare occasions, a severe contracture may present in hemiplegia, where there is an indication to gain extension for a specific func- tional gain or cosmetic concern. Treatment with an extension osteotomy of the distal humerus is a safer and simpler approach than trying to do a com- plete capsulotomy. Elbow joint resection with a flexor release has been re- ported as a treatment of severe elbow flexion contractures,19but we have no experience with this procedure. Complications of Treatment Complications of elbow flexor release are rare. The most serious com- plication is injury to the brachial artery or the medial nerve during flexor lengthening. This complication is best avoided by doing the lengthenings through an open incision and under tourniquet control for optimal visuali- zation of the operative field. Loss of elbow flexor power is only of con- cern in a few individuals with very heavy use of the extremity. Lack of ac- tive flexion has never been encountered and complaints of elbow weakness are almost never reported. Most individuals are happy with the degree of improvement. Radial Head Dislocation Radial head dislocation is a relatively common problem in severe quadri- plegia with elbow flexion contracture and pronation contracture. Radial head dislocation reportedly occurs in 2% of all children with CP involving the upper extremity when elbow radiographs are carefully evaluated.
