TIPIC Syndrome: Beyond the Myth of Carotidynia, a New Distinct Unclassified Entity.

Background And Purpose: The differential diagnosis of acute cervical pain includes nonvascular and vascular causes such as carotid dissection, carotid occlusion, or vasculitis. However, some patients present with unclassified vascular and perivascular changes on imaging previously reported as carotidynia. The aim of our study was to improve the description of this as yet unclassified clinico-radiologic entity.

Effect of fasting and feeding on measurement of carbon dioxide production using doubly labeled water.

The doubly labeled water method is a noninvasive technique for measurement of rates of CO2 production and total energy expenditure in free-living human subjects. The experimental protocol used in validation studies usually involves prolonged fasting before and after the isotope dose is given to start the study, although it is not clear whether this intrusive aspect of the method is necessary. We investigated this issue in four healthy adults [3 women and 1 man: age 29 +/- 2 (SD) yr, body mass index 22 +/- 2.

Decreased HDL cholesterol in subclinical hypothyroidism: the effect of L-thyroxine therapy.

Thyroid function and lipid tests were measured in 29 premenopausal women with subclinical hypothyroidism. This group was compared with 41 euthyroid women matched for age and metabolic parameters. In basal condition there was no difference in thyroid hormone levels between the two groups except for TSH concentration (P less than 0.
