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.
Eventually the fontanelles close as the cranial bones grow together. The posterior fontanelle usually closes about two months after birth; the sphenoid fontanelle closes at about three months, the mastoid fontanelle closes near the end of the first year, but the anterior one may not close until the middle or end of the second year.
