Treatment of Paget's disease of bone with synthetic salmon calcitonin.

Thirteen patients with painful Paget's disease of bone were treated as outpatients with low doses of synthetic salmon calcitonin 22.5-50 mug three times weekly. Treatment produced full remission of pain in a mean time of 5.5 weeks and a mean depression of serum alkaline phosphatase activity of 33%.The interval before symptomatic relief could not be predicted from the variables studied. The ultimate fall in serum alkaline phosphatase activity, however, could be predicted from the initial levels and from the early rate of decrease (P < 0.001). Biochemical resistance to treatment, which occurred in three cases, could be related to the dose and duration of treatment.Prolonged remissions of pain may occur which are not related to biochemical remission, to the dose of calcitonin, or to the duration of treatment. The side effects attributable to salmon calcitonin were transient nausea (in nine patients), transient flushing (in four), diarrhoea (in two), and rash (in one) though in only one patient did treatment have to be withdrawn prematurely because of these effects.

Applying economic principles to health care.

Applying economic thinking to an understanding of resource use in patient care is challenging given the complexities of delivering health care in a hospital. Health-care markets lack the characteristics needed to determine a "market" price that reflects the economic value of resources used. However, resource allocation in a hospital can be analyzed by using production theory to determine efficient resource use. The information provided by hospital epidemiologists is critical to understanding health-care production processes used by a hospital and developing economic incentives to promote antibiotic effectiveness and infection control.

Total hip and total knee arthroplasty in juvenile rheumatoid arthritis.

Total hip arthroplasty (THA) or total knee arthroplasty (TKA) is indicated for patients with juvenile rheumatoid arthritis (JRA) when marked joint destruction is present and pain or deformity compromises function despite optimal medical therapy. Relief of pain, reduction of the deformity, and dramatic improvement in functional status and quality of life can be achieved in most patients. Functional impairment and deformity rather than pain are usually the primary indications for THA or TKA. When there is both hip and knee involvement, hip arthroplasty should probably be done first. Regional anesthetic appears to be the anesthetic of choice. Careful preoperative planning and the availability of custom and minisized components are essential. Small bone size, osteoporosis, and severe soft tissue disease make the surgery technically demanding. Skeletal immaturity may not contraindicate surgery if the patient is otherwise bedridden with progressive deformity. In the hip trochanteric osteotomy is often necessary for adequate exposure, with the possible exception being a patient with juvenile ankylosing spondylitis who is subject to heterotopic bone formation. Although complete capsulectomy and psoas tenotomy may be necessary to relieve a hip flexion contracture, a soft tissue release that produces leg lengthening may lead to nerve palsy. In the hip component loosening has been less common in patients with JRA than in other young patients who have undergone THA, but it is still the most frequent cause of failure. In the knee preoperative and postoperative serial casts can aid in the correction of severe flexion contracture. Secondary patellar pain has been the most common cause of late failure. Patellar resurfacing should probably be performed at the time of the original knee arthroplasty in all patients with JRA.
