Glucose tolerance tests and diurnal profiles of glucose, insulin, free fatty acids, serum triglycerides, total and high-density lipoprotein cholesterol levels were performed in 8 male patients with mild essential hypertension as well as in 20 normotensive subjects. Although glucose tolerance and postprandial glucose levels appeared equal in both groups, the insulin response after a glucose load and after each meal was significantly increased in hypertensive subjects as compared with the controls (p less than 0.01). The levels of free fatty acids were higher in the postabsorptive phase of patients with hypertension in comparison to normotensive subjects, but decreased markedly when plasma insulin levels rose after meals. In both subject groups serum triglyceride levels showed the typical postprandial increase. Total and high-density lipoprotein cholesterol levels showed neither diurnal variations nor differences between hypertensive subjects and normotensive controls. Postprandial hyperinsulinemia in patients with mild essential hypertension possibly may provoke lipid accumulation in the arterial wall and therefore may be a relevant risk factor for atherosclerosis in these subjects.

Auditory and somatosensory evoked potentials in a case of "locked-in" syndrome: a clinical and pathological study.

Brainstem auditory evoked potentials were bilaterally normal, and somatosensory evoked potentials were unilaterally abnormal in a patient with a large pontine infarct causing a "locked-in" syndrome. In the post mortem examination, the lesion extended unilaterally into the pontine tegmentum, partially involving the left medial lemniscus. The P14 potential was absent and the N20 potential was diminished in amplitude with right median nerve stimulation. The origin of the P14 potential has been debated in the literature. This case provides evidence for the P14 generator being located at the pontine level, in relation to a lemniscal area above the decussation of the somatosensory pathway. Evoked potentials can help to determine the tegmental extension of the pontine infarcts in the "locked-in" syndrome, especially in patients unable to cooperate with clinical examination.
