The non-dry 'dry eye' complex.

Abstract

Tactile sensations may derive from non-specific stimuli and lead to erroneous diagnosis and treatment. A perception of dryness may be caused by non-dry conditions of which four are presented here: (1) lid margin touch, (2) conjunctival laxity, (3) cilia touch, and (4) fibrin accumulation in conjunctival inflammation.

Four-dimensional sonographic assessment of fetal facial expression early in the third trimester.

OBJECTIVE: To evaluate the characteristic patterns of facial expression in fetuses aged from 28 to 34 weeks using 4-dimensional (4-D) ultrasonography. METHODS: The faces of 10 healthy fetuses aged from 28 to 34 weeks were recorded continuously for 15 min with a 4-D ultrasonographic machine performing up to 25 frames per second. The occurrence rates of blinking, mouthing, yawning, tongue expulsion, smiling, scowling, and sucking were evaluated. RESULTS: Mouthing was the most frequent facial expression (median, 6.5; range, 2-19) whereas the least frequent were scowling (median, 1; range, 0-9) and sucking (median, 1; range, 0-2). Mouthing was evident in all fetuses and significantly more frequent than any other movement (P<.05). Yawning (median, 3; range, 0-6), smiling (median, 2; range, 0-9), and blinking (median, 1.5; range, 0-6) were observed in most cases. Tongue expulsion (median, 1.5; range, 0-5), scowling, and sucking were each observed in 6 cases. CONCLUSION: 4-D sonography provides a means of evaluating fetal facial expression early in the third trimester. It may be a key to predicting fetal brain function and well-being and an important modality in future fetal neurophysiologic research.

Motor system inhibition in dopa-responsive dystonia and its modulation by treatment.

Dopa-responsive dystonia (DRD) causes dystonia-parkinsonism, which is abolished by levodopa. The authors assessed short intracortical inhibition and facilitation, silent period, blink reflex recovery cycle, and reciprocal inhibition in seven patients with DRD on and off treatment. Short intracortical inhibition and blink reflex recovery cycle were reduced, but increased with treatment. Silent period was normal on and off treatment. Third phase of reciprocal inhibition was reduced on and off treatment. A discrete pattern of motor inhibitory dysfunction occurs in DRD.
