| acute chorea | A postinfectious chorea appearing several months after a streptococcal infection with subsequent rheumatic fever.

Improvement occurs over weeks or months and exacerbations occur without associated infection recurrence.

| acute crescentic glomerulonephritis | <nephrology> A relatively uncommon (affecting 1 out of 10,000 people) form of acute glomerulonephritis that results in damage within the glomerulus of the kidney. There is rapid loss of kidney function with the formation of crescents on microscopic analysis (kidney biopsy). This disorder may result in acute glomerulonephritis or nephrotic syndrome, but ultimately results in renal failure and end-stage renal disease. Symptoms include smoky coloured urine (pyuria), decreased urine output, swelling and hypertension. Any conditions which can cause a vasculitis increase the risk of this disorder. Some examples include lupus, Goodpasture's syndrome, Henoch-Schonlein purpura, IgA nephropathy, membranoproliferative glomerulonephritis, anti-glomerular basement membrane antibody disease, history for malignant tumours and exposure to hydrocarbon solvents.

| acute cutaneous leishmaniasis | A form of cutaneous leishmaniasis characterised by rural distribution of human cases near infected rodents, particularly communal ground squirrels; characterised by acute rapidly developing dermal lesions that become severely inflamed, with moist necrotizing sores or ulcers that heal in two to eight months after a two to four month incubation period; among nonimmune immigrants, multiple lesions may develop, which heal more slowly and leave disabling or disfiguring scars. A strong delayed hypersensitivity and involvement of immune complexes play a role in necrosis, which is part of the healing process and of the strong specific immunity that follows. Synonym: acute cutaneous leishmaniasis, rural cutaneous leishmaniasis, wet cutaneous leishmaniasis. (05 Mar 2000) |

| acute disseminated myositis | The occurrence of multiple foci of acute inflammation in the muscular tissue and overlying skin in various parts of the body, accompanied by fever and other signs of systemic infection.
