A sural nerve biopsy is not required to diagnose most peripheral neuropathies, and conventional methods of clinical investigation such as electromyography, nerve conduction velocity, quantitative sensory and autonomic testing, and relevant laboratory assessment should be performed before embarking on this procedure (5).
Video: Baby's soft spots (fontanels) A baby's skull consists of several bones, and there are soft spots â or fontanels â where they meet. A baby's soft spots are covered by a thick fibrous layer. The soft spots are safe to touch and typically close within 12 to 18 months, when the skull bones fuse together. June 28, 2016.
Joints called cranial sutures, made of strong, fibrous tissue, hold the bones of your baby's skull together until the bones fuse, normally around age 2. Until then, the sutures intersect at the fontanels, the soft spots on your baby's head. The largest of the four fontanels is at the front of the skull (anterior). The anterior fontanel is the soft spot you feel just behind your baby's forehead. The next largest is at the back (posterior). Each side of the skull has a tiny fontanel.
