Natural killer (NK) cell number and function were determined in 69 systemic sclerosis (SSc) patients (41 with diffuse cutaneous SSc, 24 with limited cutaneous SSc, and 4 with scleroderma in an overlap syndrome). The results were compared with those obtained from 5 patients with Raynaud's disease and from 27 normal controls. Natural and antibody-dependent killing was reduced in the total group of SSc patients compared with controls, but these differences were primarily attributable to patients with the diffuse form of the disease who were seen early in their illness (less than 5 years after onset). NK cell numbers were not significantly reduced in patients compared with controls, although lower numbers were observed in individuals with early diffuse disease. Other clinical parameters, such as treatment with D-penicillamine or the presence of scleroderma-specific autoantibodies, did not exert an independent effect on NK cell function. These findings suggest a possible central role for NK cells in the pathogenesis of SSc.

Five mentally disturbed patients had flexion contractures of the middle, ring, and little fingers of one or both hands. All gave a history of psychiatric illness manifested by depression. Since no organic etiology for the contractures was found, the authors name this condition the "psycho-flexed hand." Four of the five patients were middle-aged women who suffered long-term depression, hypochondriasis, and/or schizophrenia. The patients' severely contracted fingers often macerated the palm. Manipulation under anesthesia and splinting only temporarily relieved the contractures. Multiple complications occurred following splinting and hand therapy, as well as surgery. Therefore, caution is urged when attempting surgical correction before resolving the mental illness.

Radial collateral ligament injuries accounted for 35% of 26 patients undergoing surgery for lateral instability of the thumb metacarpophalangeal joint in a 3-year period. Nine patients with chronic radial instability presented with significant disability but with a symptom complex distinct from the weak pinch and grasp of chronic ulnar instability. Functional and clinical stability was obtained in these patients with a surgical procedure that consisted of repair of the callateral ligament at the site of injury, distal advancement of the abductor pollicis brevis tendon, and repair of the abductor aponeurosis.
