Skin Tests
|
D012882 |
[Epicutaneous or intradermal application of a sensitizer for demonstration of either delayed or immediate hypersensitivity. Used in diagnosis of hypersensitivity or as a test for cellular immunity.

|
Skin Transplantation
|
D016038 |
[The grafting of skin in humans or animals from one site to another to replace a lost portion of the body surface skin.

|
Skin Ulcer
|
D012883 |
[An ULCER of the skin and underlying tissues.

|
Skin Window Technique
|
D012884 |
[A technique to study CELL MIGRATION in the INFLAMMATION process or during immune reactions. After an area on the skin is abraded, the movement of cells in the area is followed via microscopic observation of the exudate through a coverslip or tissue culture chamber placed over the area.

Skin and Connective Tissue Diseases
|
D017437 |
[A collective term for diseases of the skin and its appendages and of connective tissue.

|
Skin, Artificial
|
D017768 |
[Synthetic material used for the treatment of burns and other conditions involving large-scale loss of skin. It often consists of an outer (epidermal) layer of silicone and an inner (dermal) layer of collagen and chondroitin 6-sulfate. The dermal layer elicits new growth and vascular invasion and the outer layer is later removed and replaced by a graft.

|
Skinfold Thickness
|
D012885 |
[The measurement of subcutaneous fat located directly beneath the skin by grasping a fold of skin and subcutaneous fat between the thumb and forefinger and pulling it away from the underlying muscle tissue. The thickness of the double layer of skin and subcutaneous tissue is then read with a caliper. The five most frequently measured sites are the upper arm, below the scapula, above the hip bone, the abdomen, and the thigh. Its application is the determination of relative fatness, of changes in physical conditioning programs, and of the percentage of body fat in desirable body weight. (From McArdle, et al., Exercise Physiology, 2d ed, p496-8)

Skull
|
D012886 |
[The SKELETON of the HEAD including the FACIAL BONES and the bones enclosing the BRAIN.
] |
|
Skull Base
|
D019291 |
[The inferior region of the skull consisting of an internal (cerebral), and an external (basilar) surface.

|
Skull Base Neoplasms
|
D019292 |
[Neoplasms of the base of the skull specifically, differentiated from neoplasms of unspecified sites or bones of the skull (SKULL NEOPLASMS).
] |
|
Skull Fracture, Basilar
|
D020205 |
[Fractures which extend through the base of the SKULL, usually involving the PETROUS BONE. Battle's sign (characterized by skin discoloration due to extravasation of blood into the subcutaneous tissue behind the ear and over the mastoid process), CRANIAL NEUROPATHIES, TRAUMATIC; CAROTID-CAVERNOUS SINUS FISTULA; and CEREBROSPINAL FLUID OTORRHEA are relatively frequent sequelae of this condition. (Adams et al., Principles of Neurology, 6th ed, p876)

|
Skull Fracture, Depressed
|
D020204 |
[A skull fracture characterized by inward depression of a fragment or section of cranial bone, often compressing the underlying dura mater and brain. Depressed cranial fractures which feature open skin wounds that communicate with skull fragments are referred to as compound depressed skull fractures.
] |
|
Skull Fractures
|
D012887 |
[Fractures of the skull which may result from penetrating or nonpenetrating head injuries or rarely BONE DISEASES (see also FRACTURES, SPONTANEOUS). Skull fractures may be classified by location (e.g., SKULL FRACTURE, BASILAR), radiographic appearance (e.g., linear), or based upon cranial integrity (e.g., SKULL FRACTURE, DEPRESSED).

|
Skull Neoplasms
|
D012888 |
[Neoplasms of the bony part of the skull.

|
Sleep
|
D012890 |
[A readily reversible suspension of sensorimotor interaction with the environment, usually associated with recumbency and immobility.
] |
|
Sleep Aids, Pharmaceutical
|
D000068776 |
[Drugs used to induce SLEEP, prevent SLEEPLESSNESS, or treat SLEEP INITIATION AND MAINTENANCE DISORDERS.
] |
|
Sleep Apnea Syndromes
|
D012891 |
[Disorders characterized by multiple cessations of respirations during sleep that induce partial arousals and interfere with the maintenance of sleep. Sleep apnea syndromes are divided into central (see SLEEP APNEA, CENTRAL), obstructive (see SLEEP APNEA, OBSTRUCTIVE), and mixed central-obstructive types.
] |
|
Sleep Apnea, Central
|
D020182 |
[A condition associated with multiple episodes of sleep apnea which are distinguished from obstructive sleep apnea (SLEEP APNEA, OBSTRUCTIVE) by the complete cessation of efforts to breathe. This disorder is associated with dysfunction of central nervous system centers that regulate respiration.
] |
|
Sleep Apnea, Obstructive
|
D020181 |
[A disorder characterized by recurrent apneas during sleep despite persistent respiratory efforts. It is due to upper airway obstruction. The respiratory pauses may induce HYPERCAPNIA or HYPOXIA. Cardiac arrhythmias and elevation of systemic and pulmonary arterial pressures may occur. Frequent partial arousals occur throughout sleep, resulting in relative SLEEP DEPRIVATION and daytime tiredness. Associated conditions include OBESITY; ACROMEGALY; MYXEDEMA; micrognathia; MYOTONIC DYSTROPHY; adenotonsilar dystrophy; and NEUROMUSCULAR DISEASES. (From Adams et al., Principles of Neurology, 6th ed, p395)

Sleep Arousal Disorders
|
D020921 |
[Sleep disorders characterized by impaired arousal from the deeper stages of sleep (generally stage III or IV sleep).
