Instructions. To find the proper medical term, scroll up and down to review the alphabetical listings. Also, you can use the "Page Up" and "Page down" key on your keyboard. Or use the search function of your browser. In both Netscape and Explorer, go to "Edit" and select "Find in Page". Type in the main term of interest. Frequently, it is best to type in only the first 4 or five letters (i.e., "prost" for prostate) because that will find more alternative terms from which to select the proper one.

Jaundice

Definition: A clinical manifestation of hyperbilirubinemia, consisting of deposition of bile pigments in the skin, resulting in a yellowish staining of the skin and mucous membranes. Annotation: GEN or unspecified; prefer specifics & note jaundice see refs ID#: D007565

Jaundice, Chronic Idiopathic

Definition: A benign, autosomally recessive inherited hyperbilirubinemia characterized by the presence of a dark pigment in the centrilobular region of the liver cells. There is a functional defect in biliary excretion of bilirubin, cholephilic dyes, and porphyrins. Affected persons may be asymptomatic or have vague constitutional or gastrointestional symptoms. The liver may be slightly enlarged, and oral and intravenous cholangiography fails to visualize the biliary tract. Annotation: ID#: D007566

Jaundice, Neonatal

Definition: A transient unconjugated hyperbilirubinemia that occurs between the second and fifth days of life because the hepatic enzyme GLUCURONOSYLTRANSFERASE required for BILIRUBIN detoxification is inadquedate. Annotation: do not use /congen & do not coord with INFANT, NEWBORN, DISEASES; check the tag INFANT, NEWBORN ID#: D007567

Jaw Abnormalities

Definition: Congenital absence of or defects in structures of the jaw. Annotation: GEN only: prefer specifics: MAXILLA /abnorm or MANDIBLE /abnorm; do not use /congen & do not coord with INFANT, NEWBORN, DISEASES ID#: D007569

Jaw Cysts

Definition: Saccular lesions lined with epithelium and contained within pathologically formed cavities in the jaw; also nonepithelial cysts (pseudocysts) as they apply to the jaw, e.g., traumatic or solitary cyst, static bone cavity, and aneurysmal bone cyst. True jaw cysts are classified as odontogenic or nonodontogenic. Annotation: non-neoplastic; /blood supply /chem /secret /ultrastruct permitted; coord IM with precoord organ/dis term (IM) ID#: D007570

Jaw, Edentulous

Definition: The total absence of teeth from either the mandible or the maxilla, but not both. Total absence of teeth from both is MOUTH, EDENTULOUS. Partial absence of teeth in either is JAW, EDENTULOUS, PARTIALLY. Annotation: note category: do not confuse with ANODONTIA (see note there); = total absence of teeth from mandible or maxilla; partial absence of teeth from mandible or maxilla = JAW, EDENTULOUS, PARTIALLY; total absence of teeth from both jaws = MOUTH, EDENTULOUS; coord IM with MANDIBLE (NIM) or MAXILLA (NIM) ID#: D007575

Jaw, Edentulous, Partially

Job's Syndrome

Definition: A disorder of neutrophils characterized by the presence of abnormal or absent chemotactic responses and hyperimmunoglobulinemia E. It is transmitted as an autosomal recessive trait and most cases reported have been in girls. Annotation: a phagocyte bactericidal syndrome ID#: D007589

Joint Deformities, Acquired

Definition: Deformities acquired after birth as the result of injury or disease. The joint deformity is often associated with rheumatoid arthritis and leprosy. Annotation: coord IM with specific joint (IM); HAND DEFORMITIES, ACQUIRED & FOOT DEFORMITIES, ACQUIRED are also available ID#: D016916

Joint Diseases

Definition: Annotation: GEN; prefer specifics; inflamm dis = ARTHRITIS ID#: D007592

Joint Instability

Definition: Lack of stability of a joint or joint prosthesis. Factors involved are intra-articular disease and integrity of extra-articular structures such as joint capsule, ligaments, and muscles. Annotation: note category ID#: D007593

Joint Loose Bodies

Definition: Fibrous, bony, cartilaginous and osteocartilaginous fragments in a synovial joint. Major causes are osteochondritis dissecans, synovial chondromatosis, osteophytes, fractured articular surfaces and damaged menisci. Annotation: note category: "fragments in a synovial joint" ID#: D007594
