Problem lists are tools to improve patient management. In the medical record, they connect diagnoses to therapy, prognosis, and psychosocial issues. Computer-based problem lists enhance paper-based approaches by enabling cost-containment and quality assurance applications, but they require clinically expressive controlled vocabularies. Because existing(More)
Definition This nerve supplies the sternocleidomastoid and trapezius muscles, which have the following functions : 1. Rotation of head away from the side of the contracting sternocleidomastoid muscle. 2. Tilting of the head toward the contracting sterno-cleidomastoid muscle. 3. Flexion of the neck by both sternocleidomastoid muscles . 4. Elevation of the(More)
Optical coherence correlation spectroscopy (OCCS) allows studying kinetic processes at the single particle level using the backscat-tered light of nanoparticles. We extend the possibilities of this technique by increasing its signal-to-noise ratio by a factor of more than 25 and by generalizing the method to solutions containing multiple nanoparticle(More)
Definitions Hyperosmia is increased olfactory acuity, and hypoosmia is diminished olfactory acuity. Anosmia, the inability to recognize odors, may be unilateral or bilateral. Dysosmia is an abnormal sense of smell. Technique Carry a vial of a nonirritating substance in your bag ; vanilla, lemon, and freshly ground coffee are good examples, and tobacco or(More)
Definition The suck reflex consists of sucking movements by the lips when they are stroked or touched. The snout reflex involves puckering or protrusion of the lips with percussion. The muscles around the mouth and base of the nose contract. In the palmomental reflex, a stimulus to the thenar area of the hand causes a reflex contraction ipsilaterally of the(More)
Definition Stroking the lateral part of the sole of the foot with a fairly sharp object produces plantar flexion of the big toe ; often there is also flexion and adduction of the other toes. This normal response is termed the flexor plantar reflex. In some patients, stroking the sole produces extension (dorsiflexion) of the big toe, often with extension and(More)
