| diffuse cutaneous mastocytosis | A benign process consisting of focal cutaneous infiltrates composed of mast cells; lesions are flat or slightly elevated, form wheals and itch when stroked; bone lesions may occur. Synonym: urticaria pigmentosa. (05 Mar 2000) |

| diffuse deep keratitis | An inflammation of the posterior corneal stroma. Synonym: diffuse deep keratitis. (05 Mar 2000) |
| diffuse emphysema | Emphysema affecting all parts of the lobules, in part, or usually the whole, of the lungs, and usually associated with a1-antiprotease deficiency emphysema. Synonym: diffuse emphysema, generalised emphysema, panacinar emphysema. (05 Mar 2000) |
| diffuse gallbladder wall thickening | <radiology> Criterion: gall bladder wall greater than 3 mm may appear thicker due to surrounding ascites, cholecystitis (acute or chronic), non-fasting state, chronic hypoalbuminaemia, hepatitis, congestive heart failure, fat in gall bladder fossa Cf: focal thickening (12 Dec 1998) |
| diffuse ganglion | A cystic swelling due to inflammatory effusion into one or several adjacent tendon sheaths. (05 Mar 2000) |
| diffuse glomerulonephritis | Glomerulonephritis affecting most of the renal glomeruli; it may lead to azotemia. (05 Mar 2000) |
| diffuse goiter | Goiter in which the morbid process involves the whole gland, as opposed to nodular goiter or thyroid adenoma. (05 Mar 2000) |
| diffuse idiopathic skeletal hyperostosis | A form of degenerative arthritis characteristically associated with flowing calcification along the sides of the vertebrae of the spine and commonly with inflammation (tendinitis) and calcification of the tendons at their attachments points to bone. Because areas of the spine and tendons can become inflamed, antiinflammatory medications (NSAIDs), such ibuprofen, can be helpful in both relieving pain and inflammation. Also called Forestier's disease. (12 Dec 1998) |
| diffuse infantile familial sclerosis | <radiology> Dysmyelinating disease, autosomal recessive, usually presents by 1 yr, specific enzyme deficiency identified, rapid spontaneous nystagmus, poikilothermia Synonym: Krabbe leukodystrophy (12 Dec 1998) |
| diffuse interstitial fibrosis | Progressive fibrous changes and scarring within the lung tissue, eventually interfering with normal gas exchange. (27 Sep 1997) |
| diffuse interstitial pulmonary fibrosis | This represents a group of pulmonary disorders (lower respiratory tract) that leads to a functional loss in the alveolar air sacs and a compromise in the diffusion of oxygen from air to blood. There is widespread inflammation and scar tissue (fibrosis) formation within the lung. The causes are varied and include: inorganic and organic dusts, gases, fumes, vapors, infections, radiation, medications, coal dust, silicosis and byssinosis. When the cause is not identifiable it is referred to as idiopathic diffuse interstitial pulmonary fibrosis (27 Sep 1997) |
| diffuse leishmaniasis | Leishmaniasis caused by several New and Old World species and strains of Leishmania (L. Mexicana amazonensis, L. M. Pifanoi, possibly L. M. Garnhami and L. M. Venezuelensis; in Ethiopia, L. Aethiopica, and unidentified leishmanial agents in Namibia and Tanzania). The condition is associated with a suppressed cell-mediated immune response, so that the non-ulcerating, non-necrotizing cutaneous lesions can spread widely over the body; great numbers of parasite-filled macrophages are found in the dermal lesions. Healing does not appear to occur unless an acquired cellular hypersensitivity can develop. Synonym: anergic leishmaniasis, diffuse leishmaniasis, disseminated cutaneous leishmaniasis, leishmaniasis tegumentaria diffusa, pseudolepromatous leishmaniasis. (05 Mar 2000) |
| diffuse mastocytosis | Infiltration of many organ systems by mast cells with varied clinical manifestations that can include fever, weight loss, flushing, bronchospasm, rhinorrhoea, palpitations, dyspnea, diarrhoea, gastrointestinal bleeding, and hypotension. Synonym: systemic mastocytosis. (05 Mar 2000) |
| diffuse mesangial proliferation | <nephrology, pathology> Inflammation of the kidney glomerulus (blood filtering portion of the kidney) due to the abnormal deposition of IgM antibody in the mesangium layer of the glomerular capillary. A form of glomerulonephritis that appears to be caused by an abnormal immune response. This disorder generally manifests as nephrotic syndrome. Symptoms include swelling, dark urine, weight gain, hypertension, anorexia and bloody urine. Acronym: MPGN (05 Jan 1998) |
| diffuse nontoxic goitre | A common cause of hyperthyroidism thought to be caused by an underlying autoimmune mechanism. (27 Sep 1997) |
| diffuse sclerosing osteomyelitis |
chronic diffuse inflammatory response of bone to low-grade infection, with inflammatory cell infiltrate, fibrous replacement of marrow, and dense sclerotic masses of trabecular bone. Polymorphonuclear leukocytes, plasma cells, and focal osteoblasts may be present. Oral lesions occur predominantly in the mandible of older persons and are often sequelae of chronic periodontal disease.

| diffraction |
Diffraction is the apparent bending and spreading of waves when they meet an obstruction. It can occur with any type of wave, including sound waves, water waves, and electromagnetic waves such as light and radio waves. Diffraction also occurs when any group of waves of a finite size is propagating; for example, a narrow beam of light waves from a laser must, because of diffraction of the beam, eventually diverge into a wider beam at a sufficient distance from the laser. ...
