| ritter disease | This is the scalded skin syndrome, a potentially serious side effect of infection with the staph (staphylococcus) bacteria that produces a specific protein which loosens the cement holding the various layers of the skin together. This allows blister formation and sloughing of the top layer of skin. If it occurs over large body regions it can be deadly (just like a large surface area of the body having been burned). It is necessary to treat scalded skin syndrome with intravenous antibiotics and to protect the skin from allowing dehydration to occur if large areas peel off. The disease occurs predominantly in children under 5 years of age. It is known formally as staphyloccoccal scalded skin syndrome. (12 Dec 1998) |

| Ritter-Rollet phenomenon | On equal electrical stimulation of motor nerve trunks, the flexor and abductor muscle groups react more readily than the extensors and adductors. (05 Mar 2000) |
| Ritter's law | A nerve is stimulated at both the opening and the closing of an electrical current. See: law of polar excitation. (05 Mar 2000) |
| Ritter's opening tetanus | The tetanic contraction that occasionally occurs when a strong current, passing through a long stretch of nerve, is suddenly interrupted. (05 Mar 2000) |
| Hardy-Rand-Ritter test | A test for colour vision deficiency using pseudoisochromatic cards. These excellent cards have not been reprinted by the American Optical Co. Since the plates were accidentally destroyed in 1965. (05 Mar 2000) |

| aaa disease | Endemic anaemia of ancient Egypt, ascribed in the Papyrus Ebers to intestinal infestation with ancylostoma; now called ancylostomiasis. (05 Mar 2000) |
| ABO haemolytic disease of the newborn | Erythroblastosis foetalis due to maternal-foetal incompatibility with respect to an antigen of the ABO blood group; the foetus possesses A or B antigen which is lacking in the mother, and the mother produces immune antibody which causes haemolysis of foetal erythrocytes.

| accumulation disease | A disease characterised by abnormal accumulation of a metabolic product in certain cells and tissues; examples include the mucopolysaccharidoses, lipoidoses. (05 Mar 2000) |
| Acosta's disease | A condition that results from prolonged exposure to high altitude. Symptoms include a continuous dry cough, shortness of breath, poor exercise tolerance, dizziness, headache, sleep difficulty, anorexia, confusion, fatigue and a rapid pulse. Treatment includes the immediate movement to a lower altitude. Prophylaxis has been accomplished successfully with the use of acetazolamide (Diamox). (27 Sep 1997) |

| Addison-Biermer disease | <haematology> A form of anaemia (low red blood cell counts) that results when the bone marrow fails to produce adequate numbers of red blood cells due to a deficiency in vitamin B12. Intrinsic factor, necessary for normal B12 absorption, may be the underlying cause for B12 deficiency if is not produced in the gastric glands (in the stomach). Origin: Gr.
