Glucan-induced keratoderma in acquired immunodeficiency syndrome.

Six of 20 patients with acquired immunodeficiency syndrome (AIDS) or AIDS-related complex receiving intravenous infusions of soluble glucan (beta-1-3 polyglucose) developed a keratoderma of the palms and soles. The eruption began during the first two weeks of therapy and resolved two to four weeks after its discontinuation. The eruption was different in appearance from our previously reported keratoderma blennorrhagica in AIDS-associated psoriasis. None of the other 735 patients with AIDS or AIDS-related complex not treated with soluble glucan developed a similar keratoderma. The correlation between receiving glucan and the hyperkeratosis is highly significant. Since glucan is a naturally occurring component of the cell walls of yeast, fungus, and some bacterial organisms, recognition of its ability to induce such a striking reaction pattern may be of general significance and interest, although the reaction itself may be limited to patients with AIDS.

Elbow moment and forces at the hands during swing-through axillary crutch gait.

We investigated swing-through axillary crutch gait (nonweight bearing on the left lower extremity) to determine the effects of gait speed, crutch length, and handle position on the forces exerted at the hands and on the moments exerted about the elbow joints. Ten healthy subjects, skilled in swing-through crutch gait, walked at three speeds using fitted crutches, at a fixed speed with four different crutch lengths, and at a fixed speed with four different handle positions. We collected ground reaction forces that exerted simultaneously on the right crutch and motion data with a force plate and three high-speed movie cameras. A biomechanical model was developed to calculate the forces exerted at the right hand and the moments exerted about the right elbow joint. Changing gait speed from slow to the normal gait of the subject showed statistically significant effects (p less than .05) on the forces at the hand. When we changed crutch heights for the subjects, we found no significant effects on the forces at the subjects' hands. Changing handle position significantly affected the moment at the elbow. Increasing the elbow-flexion angle above 30 degrees by raising the crutch handle 1 to 2 in resulted in a 100 percent increase in elbow-extension moment. We found a correlation of .82 between actual average elbow-flexion angle and elbow-extension moment. Changing gait speed or crutch length did not affect elbow moment.
