Care of the adolescent undergoing an allograft procedure.

During the last 25 years, substantial progress has been made in the detection and treatment of bone tumors in adolescents and young adults. Due to more effective chemotherapy treatments, patients are now surviving these illnesses and living quality lives. In the past, the only surgical option for treatment of these tumors was amputation. Today, however, limb-sparing procedures such as allograft implantation, together with effective chemotherapy treatments, provide patients with another treatment option. The allograft procedure includes removing the tumor and affected bone and replacing it with bone procured from deceased donors. During the following 2 years, the body does the work of incorporating the allograft and replacing it, at least in part, with new host bone. After a long rehabilitation process, the patient will have a functioning limb. Nursing care of the adolescent undergoing allograft procedure encompasses meeting important physical and psychosocial needs. Adolescents are often still dealing with the emotional and physical stress of having cancer and chemotherapy or chemotherapy side effects at the time of surgery. They are concerned not only with their immediate recovery but also with their long-term prognosis. All treatment modalities, including allograft surgery, impinges on the normal developmental tasks of adolescents. The nursing challenge is to help the adolescent balance the limits of their illness and recovery with normal developmental needs.

A strength training program for postmenopausal women: a pilot study.

This pilot study examined a specific exercise program designed for skeletal muscle strengthening in postmenopausal women. The program consisted of patterns of movement using diagonal and spiral patterns, superimposed on a progressive weight-bearing sequence from prone lying to standing. Progressive resistance was provided with the use of progressively thicker elastic straps. Eighteen of an initial 22 healthy volunteer women aged 50 to 64 years completed 8 weekly hour-long group exercise sessions supplemented with twice weekly sessions at home to pilot test the program's safety, acceptability, and effectiveness in changing muscle strength. A physical therapist conducted baseline and final quadriceps, hamstrings, and grip strength assessments using a portable isokinetic dynamometer. Participants achieved a 21% increase in quadriceps (p < or = .001), 9% increase in hamstrings (p < or = .07), and a 14% increase in grip strength (p < or = .002). A positive dose-response relationship was observed between strength gains and compliance with the program. This approach to strength training in postmenopausal women is feasible and effective in increasing muscle strength. It has considerable promise and deserves further testing and evaluation.
