Fibrosclerotic lymphedema: pathophysiology and therapy.

We describe our experience with 12 patients with severe fibrotic lymphedema treated between 1979 and 1987. Each patient initially underwent nonoperative treatment (postural drainage and pneumatic compression) and in 10 patients who required operation, these measures were continued postoperatively. Operation included excision of subcutaneous tissue (debulking), which was extensive in 8 and limited in 2 patients. Only 2 patients were satisfactorily managed by nonoperative treatment alone. Based on the extensive pathophysiologic changes that occur in the tissue microenvironment with lymph stasis, it is unlikely that at this advanced stage of lymphedema that nonoperative treatment alone or "physiologic" operations such as lymphatic-venous shunt or lymphatic collector reconstruction is satisfactory. Rather, nearly all such patients require limited or extensive excision of the fibrotic-edematous subcutaneous tissue.

The effect of grip strength on radial bone in postmenopausal women.

This communication explores the correlation in 255 postmenopausal women of grip strength to bone tissue density (BTD) and cross-sectional area (CSArea) of the radius. While grip strength correlated cross-sectionally with the baseline measures of both BTD and CSArea, grip strength affected differentially the changes that transpired in the two bone parameters over the 3 years of the study. Thus, the increases in the CSArea of the radius were significantly enhanced by higher grip strength, while BTD losses were not. Since the power of muscle contraction is a factor in the mechanical loading of a bone, it is argued that the differential effects of grip strength on the two bone parameters of the radius suggest that moderate loading can effect favorable changes in the geometry of the bone, without necessarily affecting changes in BTD.

Functions of dietetic personnel in ambulatory care.

By observation in ten ambulatory care settings and a literature review, the author found that dietetic service is being delivered by a variety of personnel--trained lay aides, nurses, and physicians, as well as professional dietitians. Employers in such settings agree that nutrition is an important component of total health care but question whether it must necessarily be delivered by dietetic personnel. The dietitian, to survive, must justify on a cost-benefit basis the unique value of her competency to the outcome of patient care. Sixty-eight nutritional care functions, appropriate for dietitians and/or dietetic technicians working in ambulatory care organizations, are identified and listed. In contrast to hospital-based, in-patient care, the author concludes that performance of these functions requires greater interest in helping others and greater flexibility, and she sees such service as the wave of the future.
