Etiology of hyperparathyroidism and bone disease during chronic hemodialysis. I. Association of bone disease with potentially etiologic factors.

The present study was prompted by the observation that, in patients with chronic renal failure being followed at this center, renal osteodystrophy developed almost exclusively in those who were treated by chronic hemodialysis at home rather than in our center. A systematic comparison was made between the 10 patients with roentgenographic evidence of the bone disease and 18 patients without demonstrable bone disease. The two groups were similar in age, sex, nature of renal disease, and duration of dialysis. The mean duration of kidney disease was almost 2 yr longer in the patients without bone disease than in those with bone disease. Other significant differences related to where the hemodialysis was performed and to the calcium concentration in the dialysate (6.0-7.4 mg/100 ml in the hospital and 4.9-5.6 mg/100 ml at home). If the unknown factors related to where the dialysis was performed were of no consequence, the major factor contributing to the production of bone disease observed in these patients was the use of a dialysate with a calcium concentration less than 5.7 mg/100 ml.

Diabetic neuroarthropathy in the foot: patient characteristics and patterns of radiographic change.

The diagnosis of diabetic neuroarthropathy of the foot can be difficult. A series of 96 patients (116 extremities) who had diabetes and peripheral neuropathy with bone and joint changes was reviewed. Typically, the patients were middle-aged or older, were taking insulin, and had had diabetes for more than 10 years. Retinopathy, nephropathy, and peripheral vascular disease were often present. There were abnormalities of vibratory sensation (94%) and of the gastrosoleus reflex (88%). The finding of specific radiographic abnormalities assisted but did not reliably differentiate neuropathy from infection. Three patterns of radiographic changes were noted: (1) at the metatarsophalangeal and interphalangeal joints, usually with underlying ulceration; (2) at the tarsometatarsal joints; and (3) in the anterior pillar-medial column of the foot, with talus, talonavicular, navicular, or naviculocuneiform destruction. Ulceration and infection in patients with patterns (2) and (3) were rare. When correlated, the demographic features, mode of presentation, physical signs, specific radiographic abnormalities, and patterns of change were distinctive and allowed the diagnosis of this complication of diabetes to be readily made.
