[Q]: Abstract: It has been shown in different groups of patients with variant angina that coronary spasm can be reproduced by physiologic maneuvers and pharmacologic agents. It is not known, however, to what extent different stimuli can induce spasm in the same patient. To investigate whether coronary arterial spasm results from specific abnormal agonist-receptor interactions or from a local nonspecific coronary supersensitivity to different stimuli, 28 patients with vasospastic angina were submitted to a series of diverse vasoconstrictive stimuli known to provoke coronary spasm. Ergonovine, hyperventilation, handgrip, cold pressor, and exercise-tests, were carried out in all 28 patients. In the last 15 patients histamine was also administered. Spasm was provoked by ergonovine in 96% of patients, by hyperventilation in 54%, by histamine in 47%, by exercise in 46%, and by the cold pressor and handgrip tests in 11% and 7%, respectively. No significant differences were found in the responses to provocative tests of patients with normal coronary arteries or nonsignificant stenoses and those with significant lesions. In the same individual, spasm was induced by at least two vasoconstrictive stimuli, although with a different mechanism of action, in 82% of patients and spasm was induced by three or more stimuli in 39%. Tests were repeated in at least 23 patients and short-term reproducibility paralleled sensitivity. These results suggest that in patients with variant angina, a local nonspecific supersensitivity rather than an abnormal specific agonist-receptor interaction plays a major role in the genesis of coronary arterial spasm.

[Q]: Abstract: Of 34 tibia fractures in 28 acute spinal cord injuries, 13 patients had complete and 15 had incomplete neurologic lesions. Tibia fractures were divided into three groups: Group I, nonoperative treatment; Group II, early open reduction and internal fixation; and Group III, Type III open injuries. Group I included 17 fractures, of which nine (53%) had delayed union, malunion, or nonunion. The average time to union was 6.5 months. Seven patients had pressure sores and pulmonary emboli. Eleven fractures were noted in Group II. One delayed union (9%), one superficial wound infection that healed uneventfully, and one deep vein thrombosis were noted. The average time to union was 12 weeks. All six Group III tibias had delayed and nonunions, regardless of treatment. Nonoperative fractures healed at a prolonged rate, while open reduction and internal fixation enhanced the rate and time to union. Fractures treated with early open reduction and internal fixation, excluding Group III patients, had the least orthopedic and medical complications. Open reduction and internal fixation is a justifiable alternative to nonoperative treatment in the uncomplicated tibia fracture regardless of neurologic lesion for improved medical and fracture care.

[Q]: Abstract: A patient is presented who developed chloracne after exposure to lumber which was pressure-treated with pentachlorophenol (PCP). It was presumed that his disease arose via percutaneous absorption of polychlorinated aromatic compounds (dioxins and furans) which are known to contaminate technical grade PCP. The patient's condition improved after treatment with oral isotretinoin.
