| generalised tonic-clonic epilepsy | tonic-clonic seizure |
|---|---|
| generalised tonic-clonic seizure | <neurology> A type of seizure that results in loss of consciousness, generalised muscle contractions, urinary incontinence, tongue biting and a post-ictal state (confusion and lethargy) following cessation of the seizure. Synonym: grand-mal seizure. See: epilepsy. (03 Jul 1999) |
| generalised vaccinia | Secondary lesions of the skin following vaccination which may occur in subjects with previously healthy skin but are more common in the case of traumatised skin, especially in the case of eczema (eczema vaccinatum). In the latter instance, generalised vaccinia may result from mere contact with a vaccinated person. Secondary vaccinial lesions may also occur following transfer of virus from the vaccination to another site by means of the fingers. (05 Mar 2000) |
| persistent generalised lymphadenopathy | A syndrome characterised by reactive hyperplasia of lymph nodes (of at least one month's duration and at two different body sites, not including the inguinal area) in patients infected with the human immunodeficiency virus. The lymph node lesions progress from benign reactive hyperplasia through a stage of mixed follicular hyperplasia, to follicular involution with lymphocyte depletion. Many go on to a malignant non-Hodgkin's lymphoma. (05 Mar 2000) |
| congenital generalised fibromatosis | Multiple subcutaneous and visceral fibrous tumours present at birth; a rare disorder often fatal in the first week of life, although sometimes undergoing spontaneous remission; probable autosomal recessive inheritance. (05 Mar 2000) |
| primary generalised epilepsy | Epilepsy without evidence of focal or multifocal central nervous system disease. Seizures are generalised from onset, both by EEG and clinical criteria. Often a pure genetic form of epilepsy. See: generalised tonic-clonic seizure. (05 Mar 2000) |
| secondarily generalised tonic-clonic seizure | A generalised tonic-clonic seizure that begins with a partial seizure and evolves into a generalised tonic-clonic seizure. (05 Mar 2000) |
| secondary generalised epilepsy | A group of epilepsy syndromes of diverse aetiologies with diffuse or multifocal cerebral involvement. Patients typically have a variety of generalised seizure types, including tonic, atonic, myoclonic, atypical absence, and generalised tonic-clonic seizures. Partial seizures may also occur. One classic syndrome is the Lennox-Gastaut syndrome. Synonym: symptomatic epilepsy. (05 Mar 2000) |
| infantile generalised GM1 gangliosidosis | One of the hereditary metabolic diseases of infancy; resembles Tay-Sachs disease, except other organ systems (bone, liver, kidney) are affected. Synonym: familial neuroviscerolipidosis, pseudo-Hurler disease, Type 1 GM1 gangliosidosis. (05 Mar 2000) |
| epilepsy, generalised | Epileptic seizures in which the first clinical changes indicate initial involvement of both hemispheres of the brain, as opposed to epileptic seizures involving a particular focal point of the brain (epilepsy, partial). Generalised seizures can be convulsive or non-convulsive. Consciousness may be impaired and this impairment may be the initial manifestation of the seizure. Motor manifestations, if present, are also bilateral. (12 Dec 1998) |
| adenoma, adrenal cortical | A benign neoplasm of adrenal cortical cells resembling normal adrenal cells histologically but possessing functional autonomy. In general it does not exceed 5 cm in its largest dimension, although benign tumours exceeding 20 cm have been reported. Adrenal cortical adenomas produce hypercortisolism and hyperaldosteronism, but seldom produce adrenogenital syndromes. For the most part the prognosis after surgery is reasonably favourable. (12 Dec 1998) |
| adrenal cortical carcinomas | Large invasive and metastasizing tumours which may cause virilism or Cushing's syndrome. (05 Mar 2000) |
| adrenal cortical syndrome | <syndrome> An inexact (and obsolete) term that has been applied to Cushing's syndrome, Addison's disease, or the adrenogenital syndrome. (05 Mar 2000) |
| blindness, cortical | Total loss of vision in all or part of the visual field due to a lesion in the striate area, characterised by the patient's subjective unawareness of his disability and the absence of cortical functions of vision, with the subcortical functions intact. (12 Dec 1998) |
| carcinoma, adrenal cortical | A malignant neoplasm of adrenal cortical cells demonstrating partial or complete histological and functional differentiation. They are rare, comprising between only 0.05% and 0.2% of all cancers. Women develop functional adrenal cortical carcinomas more commonly than men, but men develop nonfunctioning ones more often than women. Hypercortisolism is the most common presentation for this cancer. Virilism and cushing's syndrome may also result. (12 Dec 1998) |
