Abstract:
Pain is one of the most debilitating symptoms in epidermolysis bullosa (EB) leading to reduced quality of life. Pain in EB comprises both neuropathic and non-neuropathic qualities. An assessment of pain qualities has not formerly been completed in EB. The Pain Quality Assessment Scale (PQAS) is an adjusted version of the validated Neuropathic Pain Scale and includes 20 pain qualities and descriptors. Patients with EB (n = 43) rated the pain qualities in the PQAS on 20 numerical scales and 1 multiple choice question. Pain was experienced by 39 patients (91%). In general, patients with EB experience intense and unpleasant pain on the surface of the skin; the hands and feet are most commonly affected. The subtypes, recessive dystrophic EB and junctional EB reported pain qualities pathognomonic of neuropathic pain. The PQAS adds value to the current practice of global pain intensity scoring in EB.

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...

Few clinical manifestations differentiate gastric ulcers from duodenal ulcers. Distinctions in the location, timing, and pain relief are crucial for healthcare providers in differentiating between gastric and duodenal ulcers during clinical assessments.
