PROBLEM: Abstract: In a survey of wheelchair use in two nursing homes, the authors found a substantial number of cognitively intact nursing home residents who walked, but who also used a wheelchair. Using chart review and interviews with the residents, it was found that multiple physical factors, including pain, strength, endurance, vision and balance, and multiple social and environmental factors, including the fear of falling, were related to the resident's decision to use a wheelchair as an alternative means of mobility. A physical examination focused on aspects of mobility was completed on each resident and was intended to characterize the physical limitations in groups studied. In the nursing home environment, use of the wheelchair is viewed by the residents as a self-initiated choice which the residents believed significantly enhanced their sense of well-being. Finally, there was minimal recognition of mobility as a problem on the part of the medical and nursing staff. The study raises a number of important issues concerning walking versus wheelchair use in the nursing home.

PROBLEM: Abstract: In a prospective study of 295 infantry recruits during 14 weeks of basic training, 41% had medial tibial pain. Routine scintigraphic evaluation in cases of medial tibial bone pain showed that 63% had abnormalities. A stress fracture was found in 46%. Only two patients had periostitis. None had ischemic medial compartment syndrome. Physical examination could not differentiate between cases with medial tibial bone pain secondary to stress fractures and those with scintigraphically normal tibias. When both pain and swelling were localized in the middle one-third of the tibia, the lesion most likely proved to be a stress fracture.

PROBLEM: Abstract: To determine the effects of age on the myocardium, the functional and structural characteristics of the heart were studied in rats at 3, 10 to 12 and 19 to 21 months of age. Systemic arterial pressure, left ventricular pressure and its first derivative (dP/dt) and heart rate were comparable in the three animal groups. In the interval between 3 and 10 to 12 months, mean myocyte cell volume per nucleus increased 53 and 26% in the left and the right ventricle, respectively. The total number of myocyte nuclei remained constant in either ventricle. In the following period, between 10 to 12 and 19 to 21 months, a 39% further cellular hypertrophy on the left side of the heart was found in association with an 18% loss of cells in the ventricle. Cell loss was accompanied by discrete areas of interstitial and replacement fibrosis in the subendocardium. In contrast, no myocardial damage was observed in the right ventricle, and the measured 35% additional enlargement of myocytes occurred without a change in cell number. Thus, the aging left ventricle is composed of a smaller number of hypertrophied cells. Cellular hypertrophy may explain the unaltered cardiac function of the aged myocardium.
