| congenital adrenal hyperplasia | <endocrinology> A genetic disorder present at birth characterised by a deficiency of the hormones aldosterone and cortisol and an overproduction of male sex hormones (androgens). In males this may manifest as enlarged penis, small testes and early development of masculine characteristics. In females features include ambiguous genitalia, failure to menstruate, deep voice and excessive hair. Origin: Gr. Plassein = to form (27 Sep 1997) |

| congenital virilizing adrenal hyperplasia | A series of inherited inborn errors of metabolism with hyperplasia of the adrenal cortex and overproduction of virilizing hormones. Most common forms are due to partial or complete 21-hydroxylase deficiency, leading to increased ACTH production by the pituitary, stimulating adrenal growth and function. Severe form is characterised by salt-losing state. (05 Mar 2000) |
| foetal adrenal cortex | An extensive area of the adrenal gland present in primates during foetal life and for a short period after birth; located between the definitive cortex and the medulla, it contains large steroid-secreting cells arranged in a reticular pattern; involution of this zone in humans is largely completed by three months after birth. Synonym: androgenic zone, foetal reticularis, foetal zone, provisional cortex. (05 Mar 2000) |
| acute miliary tuberculosis | A rapidly fatal disease due to the general dissemination of tubercle bacilli in the blood, resulting in the formation of miliary tubercles in various organs and tissues, and producing symptoms of profound toxaemia. Synonym: acute miliary tuberculosis, disseminated tuberculosis. (05 Mar 2000) |
| acute tuberculosis | A rapidly fatal disease due to the general dissemination of tubercle bacilli in the blood, resulting in the formation of miliary tubercles in various organs and tissues, and producing symptoms of profound toxaemia. Synonym: acute miliary tuberculosis, disseminated tuberculosis. (05 Mar 2000) |
| adult tuberculosis | Tuberculosis found in adults and characterised by lesions near the apex of an upper lobe, which may cavitate or heal with scarring without spreading to lymph nodes; theoretically, secondary tuberculosis may be due to exogenous reinfection or to reactivation of a dormant endogenous infection. Synonym: adult tuberculosis, postprimary tuberculosis, reinfection tuberculosis. (05 Mar 2000) |
| aerogenic tuberculosis | Infection with the Mycobacterium tuberculosis spread by inhalation of infected droplets. (05 Mar 2000) |
| anthracotic tuberculosis | <chest medicine> Fibrosis and scarring of the lungs secondary to the repeated inhalation of dust associated with some occupation. Examples include silica, asbestos and coal dust exposure. (29 Oct 1998) |
| arrested tuberculosis | A scar or a calcified, fibrous, or caseous nodule in the lung pleura, lymph node, or other organ, resulting from previous tuberculosis that has regressed; reactivation is possible. Synonym: arrested tuberculosis, inactive tuberculosis. (05 Mar 2000) |
| attenuated tuberculosis | A mild chronic form marked by caseous tubercles of the skin and the occurrence of cold abscesses. (05 Mar 2000) |
| basal tuberculosis | Tuberculosis of the basilar portions of the lungs. (05 Mar 2000) |
| general tuberculosis | Usually a chronic tuberculosis infection where spread of the original primary infection has occurred via the patients lymphatic system (or bloodstream). Disseminated disease occurs primarily in the immunocompromised individual (for example AIDS, cancer patient). The elderly are at increased risk for dissemination. In disseminated disease, organs and tissues that can be affected include pericardium, peritoneum, larynx, bronchus, bone, joints, lymph nodes, stomach, meninges, eyes, kidneys and skin. Treatment is with INH, rifampin, ethambutol and other antibiotics. (27 Sep 1997) |
| reinfection tuberculosis | Tuberculosis found in adults and characterised by lesions near the apex of an upper lobe, which may cavitate or heal with scarring without spreading to lymph nodes; theoretically, secondary tuberculosis may be due to exogenous reinfection or to reactivation of a dormant endogenous infection. Synonym: adult tuberculosis, postprimary tuberculosis, reinfection tuberculosis. (05 Mar 2000) |
| cerebral tuberculosis | Inflammation of the cerebral leptomeninges marked by the presence of granulomatous inflammation; it is usually confined to the base of the brain (basilar meningitis, internal hydrocephalus) and is accompanied in children by an accumulation of spinal fluid in the ventricles (acute hydrocephalus). Synonym: cerebral tuberculosis. (05 Mar 2000) |
| childhood tuberculosis | Initial (primary) infection with Mycobacterium tuberculosis, characterised by pneumonic lesions in middle parts of lungs, rarely cavitary, with rapid spread to lymph nodes in hilar and paratracheal areas; more often seen in childhood, but pattern is not limited to children.
