| sexually transmitted diseases in women | Gonorrhoea and chlamydia are bacterial sexually transmitted diseases (stds) frequently found together. Gonorrhoea is not transmitted from toilet seats. Women infected with it may not have any symptoms but can end up later with severe pelvic infection. Early syphilis causes a mouth or genital ulcer (chancre) and later can cause hair loss, headaches, sore throat, and skin rash. Even later, syphilis can lead to heart and brain damage. Genital herpes is a viral infection that can cause painful genital sores. Genital warts are caused by viruses and can increase a woman's risk for cancer of the cervix. Aids is caused by the human immunodeficiency virus (HIV). Hepatitis b is a virus that causes liver inflammation and can lead to cirrhosis and cancer of the liver. Hepatitis b can now be prevented with a vaccine. There is no safe sex. Condoms do not necessarily prevent stds. (12 Dec 1998) |

| sheep diseases | Diseases of domestic and mountain sheep of the genus ovis. (12 Dec 1998) |
| single-gene diseases | Hereditary disorders caused by a change (mutation) in a single gene. There are thousands of single-gene diseases including achondroplastic dwarfism, huntington disease, cystic fibrosis, sickle cell disease, duchenne muscular dystrophy, and haemophilia. Single-gene diseases typically describe classic simple mendelian patterns of inheritance (as autosomal dominant, autosomal recessive, and x-linked traits) by comparison with polygenic diseases.

| skin diseases, bacterial | Skin diseases caused by bacteria. (12 Dec 1998) |
| skin diseases, eczematous | Any of a variety of eruptive skin disorders characterised by erythema, oozing, vesiculation, and scaling. Aetiology is varied. (12 Dec 1998) |
| skin diseases, genetic | Diseases of the skin with a genetic component, usually the result of various inborn errors of metabolism. (12 Dec 1998) |

| skin diseases, papulosquamous | A group of dermatoses with distinct morphologic features. The primary lesion is most commonly a papule, usually erythematous, with a variable degree of scaling on the surface. Plaques form through the coalescing of primary lesions. (12 Dec 1998) |

| skin diseases, vesiculobullous | Skin diseases characterised by local or general distributions of blisters. They are classified according to the site and mode of blister formation. Lesions can appear spontaneously or be precipitated by infection, trauma, or sunlight. Aetiologies include immunologic and genetic factors. (12 Dec 1998) |
| skin diseases, viral | Skin diseases caused by viruses. (12 Dec 1998) |
| slow virus diseases | Diseases of viral origin, characterised by incubation periods of months to years, insidious onset of clinical manifestations, and protracted clinical course. Though the disease process is protracted, viral multiplication may not be unusually slow. Conventional viruses produce slow virus diseases such as subacute sclerosing panencephalitis, progressive multifocal leukoencephalopathy (leukoencephalopathy, progressive multifocal), and aids. Diseases produced by unconventional agents were originally considered part of this group. They are now called prion diseases. (12 Dec 1998) |
