Reserpine in propranolol-resistant thyroid storm.

beta-Adrenergic blockers are considered the drugs of choice in the management of the hyperadrenergic state in hyperthyroidism. However, we observed a patient in thyroid storm and coma who failed to respond to large doses of oral and intravenous propranolol hydrochloride but who responded promptly to intramuscular reserpine. Reserpine may have been lifesaving and should be considered in propranolol-resistant hyperthyroidism and in hyperthyroid patients in whom propranolol is contraindicated.

Biochemical markers of bone metabolism.

Bone metabolic homeostasis is regulated by a number of hormones and local modulators, and the study of these factors has been of major help in our understanding of bone disease. However, these parameters do not, in a strict sense reflect the metabolic and biochemical changes in the diseased bone tissue. Thus, there is a great interest in the study of biochemical specific "markers" of bone metabolic processes, namely of bone formation and bone resorption. Alkaline phosphatase, osteocalcin, osteonectin, and procollagen type I propeptides are the currently known markers of bone formation, whereas urinary hydroxyproline and hydroxylysine glycosides, plasma tartrate resistant acid phosphatase, and urinary hydroxy-pyridinium crosslinks of collagen are considered markers of bone resorption. In this paper, we review the background work on each of these markers, and subsequently give an overview of the currently available data on their usefulness in metabolic bone diseases, namely in Paget's disease of bone, primary hyperparathyroidism, osteoporosis, and renal osteodystrophy.
