| oesophageal stricture, acute | A narrowing or closure of the normal opening of the swallowing tube leading to the stomach, usually caused by scarring from acid irritation. Acute, complete obstruction of the oesophagus occurs when food (usually meat) is lodged in the oesophageal stricture. Patients experience chest pain, and are unable to swallow saliva. Attempts to relieve the obstruction by inducing vomiting at home are usually unsuccessful. Patients with complete oesophageal obstruction can breathe, and are not at any risk of suffocation. Endoscopy is usually employed to retrieve the meat and relieve the obstruction. (12 Dec 1998) |

| encephalomyelitis, acute disseminated | An acute or subacute encephalomyelitis or myelitis characterised by perivascular lymphocyte and mononuclear cell infiltration and demyelination. It occurs most commonly following an acute viral infection, especially measles, but may occur without a recognizable antecedent, and formerly occurred as a complication of rabies and smallpox vaccination. (12 Dec 1998) |
| kidney failure, acute | A clinical syndrome characterised by a sudden decrease in glomerular filtration rate, often to values of less than 1 to 2 ml per minute. It is usually associated with oliguria (urine volumes of less than 400 ml per day) and is always associated with biochemical consequences of the reduction in glomerular filtration rate such as a rise in blood urea nitrogen (bun) and serum creatinine concentrations. (12 Dec 1998) |
| leukaemia, erythroblastic, acute | A myeloproliferative disorder characterised by neoplastic proliferation of erythroblastic and myeloblastic elements with atypical erythroblasts and myeloblasts in the peripheral blood. (12 Dec 1998) |
| leukaemia, megakaryocytic, acute | Nonlymphocytic leukaemia in which 20-30% of the bone marrow or peripheral blood cells are of megakaryocyte lineage. Myelofibrosis or increased bone marrow reticulin is common. (12 Dec 1998) |
| leukaemia, myelocytic, acute | Progressive, malignant disease of the myeloid tissue in which the granular, polymorphonuclear leukocytes and their precursors predominate. (12 Dec 1998) |
| leukaemia, nonlymphocytic, acute | Acute leukaemia distinguished from acute lymphocytic leukaemia (all) by the morphology of the marrow and blood leukaemic cells. Cytoplasmic granules are usually present and the nucleus is usually large and irregular. Anll is more common in adults than all and occurs at any age. (12 Dec 1998) |
| leukoencephalitis, acute haemorrhagic | A rare, fatal postinfection or allergic demyelinating disease of the central nervous system having a fulminating course and occurring mainly in young adults. It is characterised by destruction of white matter to the point of liquefaction; widespread necrosis of blood vessel walls leading to the formation of multiple small haemorrhages in the involved areas and the exudation of fibrin into the surrounding tissue; and cellular infiltration of the necrotic areas. (12 Dec 1998) |
| liver failure, acute | A form of liver failure with rapid onset. It is often induced by the toxic effect of drugs and various toxic substances in experimental studies in animals and in clinical states in humans. If coma ensues, the constellation of neurological symptoms is referred to as hepatic encephalopathy. (12 Dec 1998) |
| Aarskog-Scott syndrome | A syndrome of ocular hypertelorism, anteverted nostrils, broad upper lip, saddle-bag scrotum, and laxity of ligaments resulting in genu recurvatum, flat feet, and hyperextensible fingers; X-linked and autosomal dominant forms. Synonym: Aarskog-Scott syndrome. (05 Mar 2000) |
| Aarskog syndrome | <syndrome> Grier et al. (1983) reported father and 2 sons with typical Aarskog syndrome, including short stature, hypertelorism, and shawl scrotum. They tabulated the findings in 82 previous cases. X-linked recessive inheritance has been repeatedly suggested. The family reported by Welch (1974) had affected males in 3 consecutive generations. Thus, there is either genetic heterogeneity or this is an autosomal dominant with strong sex-influence and possibly ascertainment bias resulting from use of the shawl scrotum as a main criterion. Stretchable skin was present in the cases of Grier et al. (1983). Teebi et al. (1993) reported the case of an affected mother and 4 sons (including a pair of monozygotic twins) by 2 different husbands. They suggested that the manifestations were as severe in the mother as in the sons and that this suggested autosomal dominant inheritance. Actually, the mother seemed less severely affected, compatible with X-linked inheritance. Clinical signs: Mild to moderate short stature,normocephaly, Widow's peak hair, maxillary hypoplasia, broad nasal bridge, anteverted nostrils, long philtrum, broad upper lip, curved linear dimple below the lower lip, hypertelorism, ptosis, down-slanted palpebral fissures, ophthalmoplegia, strabismus, hyperopic astigmatism, large cornea, floppy ears, lop-ears,cleft lip/palate, shawl scrotum, saddle-bag scrotum, cryptorchidism, brachydactyly, digital contractures, clinodactyly, mild syndactyly, transverse palmar crease, lymphoedema of the feet, ligamentous laxity, osteochondritis dissecans, proximal finger joint hyperextensibility, flexed distal finger joints, genu recurvatum, flat feet, stretchable skin, cervical spine hypermobility, odontoid anomaly, macrocytic anaemia, hemochromatosis, hepatomegaly, portal cirrhosis, imperforate anus, rectoperineal fistula, interstitial pulmonary disease, sternal deformity. Inheritance: Sex-influenced autosomal dominant form, also X-linked form. (05 Aug 1998) |
| abdominal muscle deficiency syndrome | <syndrome> Congenital absence (partial or complete) of abdominal muscles, in which the outline of the intestines is visible through the protruding abdominal wall; in males, genitourinary anomalies (urinary tract dilation and cryptorchidism) are also found; genetics unclear. (05 Mar 2000) |
| abstinence syndrome | <syndrome> A constellation of physiologic changes undergone by persons or animals who have become physically dependent on a drug or chemical due to prolonged use at elevated doses, but who are abruptly deprived of that substance. The abstinence syndrome varies with the drug to which dependence has developed. Generally the effects observed are in an opposite direction from those produced by the drug; e.g., the withdrawal syndrome from central nervous system depressants such as barbiturates and benzodiazepines consists of insomnia, restlessness, tremulousness, hallucinations, and, in the extreme, tonic-clonic convulsions which may prove fatal. The onset time and severity of the abstinence syndrome depend upon how rapidly the drug disappears from the body. (05 Mar 2000) |
| Achard syndrome | <syndrome> Arachnodactyly with small receding mandible, broad skull, and joint laxity limited to the hands and feet; genetics unclear. (05 Mar 2000) |
| Achard-Thiers syndrome | <syndrome> One form of a virilizing disorder of adrenocortical origin in women, characterised by masculinization and menstrual disorders in association with manifestations of diabetes mellitus, such as glucosuria. (05 Mar 2000) |
