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.
A baby might have a cone shaped head after birth, but this usually quickly reshapes into a round head over a couple days. There are 1-2 soft spots at birth. Usually the one on top to the head (the anterior fontanelle) remains open enough to feel for the first 18-24 months of life.
