Quantitative Evaluation of Cutaneous Thermal Sensation in Psoriasis, Morphoea and Vitiligo
Abstract:
A quantitative assessment of cutaneous thermal sensation was undertaken in 12 psoriasis, 7 morphoea and 12 vitiligo patients. The thermal sensory threshold (TST) was determined both at the lesion site and the lesion-Eree contralateral site (control) by an electronic device fitted with a probe and a temperature sensor. As the differences in T-ST between the contralateral regions hardly exc I eed I'C in normal individuals a difference in TSC was considered significant. It was observed that about 83% of psoriasis and 71% of morphoca cases showed a significant differencrin TST (3C), but no such difference existed among the vitiugo patients.

Sensory Functions of the Skin
There are two main categories of receptors on the skin: capsulated and non-capsulated. The non-capsulated ones are mainly the pain receptors. The capsulated ones can be further categorized based on the...

Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above...
