Abstract:
The inflammatory myopathies are a group of immune-mediated inflammatory muscle disorders that typically present with marked proximal muscle weakness. We report four cases of inflammatory myopathies with marked subcutaneous oedema as their main complaint. Three of the four patients had normal or low levels of creatine kinase, an enzyme often markedly elevated in these disorders. Magnetic resonance imaging of the muscles, followed by a muscle biopsy were used to make a definitive diagnosis.

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...
