| laryngeal diseases | Disorders of the larynx, general or unspecified. (12 Dec 1998) |
| lipid storage diseases | A series of disorders due to inborn errors in lipid metabolism resulting in the abnormal accumulation of lipids in the wrong places (examples include gaucher, fabry and niemann-pick diseases and metachromatic leukodystrophy). (12 Dec 1998) |
| liver diseases, alcoholic | Liver diseases associated with alcoholism. It usually refers to the coexistence of two or more subentities, i.e., alcoholic fatty liver, alcoholic hepatitis, and alcoholic liver cirrhosis, but may be the general entity when subentities are not specified. (12 Dec 1998) |
| liver diseases, parasitic | Infections of the liver with a parasite. They are caused most commonly by trematodes (flukes). (12 Dec 1998) |
| lung diseases, interstitial | A heterogeneous group of noninfectious, nonmalignant disorders of the lower respiratory tract, affecting primarily the alveolar wall structures but also often involving the small airways and blood vessels of the lung parenchyma. "interstitial" refers to the fact that the interstitium of the alveolar walls is thickened, usually by fibrosis. This group of diseases is usually inflammatory. (12 Dec 1998) |
| lung diseases, obstructive | Any disorder marked by persistent obstruction of bronchial air flow. (12 Dec 1998) |
| lung diseases, parasitic | Infections of the lungs with a parasite. They are caused most commonly by nematodes (roundworms). (12 Dec 1998) |
| lymphatic diseases | Diseases of lymph or lymph vessels. (12 Dec 1998) |
| lysosomal diseases | Diseases (also called storage diseases) in which a deficiency of a particular lysosomal enzyme leads to accumulation of the undigested substrate for that enzyme within cells. Not immediately fatal, but within a few years lead to serious neurological and skeletal disorders and eventually to death. See: the following conditions: Hurler sundrome, Hunter syndrome, San Fillipo, Gaucher's disease, Niemann-Pick, Pompe's disease, Tay Sachs disease. (18 Nov 1997) |
| lysosomal storage diseases | Inborn errors of metabolism characterised by defects in specific lysosomal hydrolases and resulting in intracellular accumulation of unmetabolised substrates. (12 Dec 1998) |
| abnormal heart chamber dimensions | <radiology> Left ventricular volume overload, left ventricular hypertrophy, right ventricular volume overload, right ventricular hypertrophy, fixed subvalvular aortic stenosis, hypoplastic left/right ventricle; common ventricle, congestive cardiomyopathy (12 Dec 1998) |
