Diseases

Tick-borne encephalitis

A viral infection (flavivirdae) of the central nervous system which is transmitted by ticks. Ticks usually feed on small rodents who are the main carriers of the virus. Transmission may also occur through the consumption of untreated milk. The incubation period is usually 1 to 2 weeks. The symptoms occur in two phases: the first involves symptoms of a general viral illness (fever, headache, nausea, aching muscles) followed by a period of remission and then central nervous system inflammation such as meningitis. However, many patients only suffer the first phase of the disease.

Tièche-Jadassohn nevus

A rare genetic disorder characterized by characteristic blue, slightly raised, sharply defined skin growths. The lesions can vary in size.

Tietz syndrome

Tietz syndrome is a condition characterized by deafness and albinism. (Tietz syndrome is not to be confused with Tietze's syndrome, which is a benign inflammation of the cartilages connecting to the sternum or ribs.)

Tietze syndrome

A rare disorder characterized by inflammation, swelling, redness and tenderness of the rib cartilage (costochondrial cartilage) in the upper chest. The condition causes pain and can last from hours to weeks. The cause of the condition is unknown. Also called Tietze's syndrome.

Tiglic acidemia

Tiglic acidemia: Increased blood tiglic acid levels due to a metabolic disorder involving the breakdown of isoleucine to propionic acid.

Timothy syndrome

Timothy syndrome is a rare autosomal dominant disorder characterized by physical malformations, as well as neurological and developmental defects, including heart QT-prolongation, heart arrhythmias, structural heart defects, syndactyly (webbing of fingers and toes) and autism spectrum disorders. Timothy syndrome often ends in early death.

Togaviridae disease

Togaviridae disease: Infection with any of a number of togaviridae viruses which can caused conditions such as Equine encephalitis, Ross River virus and Rubella virus. Symptoms are determined by the type of virus involved. Togaviridae are arboviruses and are transmitted by arthropods.

Tollner Horst Manzke syndrome

Tollner Horst Manzke syndrome (medical condition): A very rare syndrome characterized by extra fingers, cleft lip, cleft palate and abdominal organ anomalies.

Tolosa-Hunt syndrome

Tolosa-Hunt syndrome (THS) is a rare disorder characterized by severe and unilateral headaches with extraocular palsies, usually involving the third, fourth, fifth, and sixth cranial nerves, and pain around the sides and back of the eye, along with weakness and paralysis (ophthalmoplegia) of certain eye muscles.

Tomaculous neuropathy

Tomaculous neuropathy (medical condition): A rare disorder where the peripheral nerves are more sensitive to pressure than normal which results in recurring periods of numbness, tingling and sometimes loss of muscle function. The condition can affect one or more nerves such as the carpal tunnel nerve. Permanent damage to peripheral nerves can result from recurring episodes. The severity of symptoms are greatly variable from virtually asymptomatic to disability.

Tome Brune Fardeau syndrome

Tome-Brune-Fardeau syndrome: A rare syndrome involving neurological impairment which manifests as movement disorders and dementia.

Tongue neoplasm

Tongue cancer is one type of cancer of the internal oral region;

Toni-Debre-Fanconi syndrome

Toni-Debré-Fanconi syndrome: Another name for Toni-Fanconi syndrome type 1 (or close medical condition association).

Toni-Fanconi syndrome

Fanconi syndrome is a disorder of the kidney tubes in which certain substances normally absorbed into the bloodstream by the kidneys are released into the urine instead.

TORCH syndrome

TORCH Syndrome: Infection of a fetus by any of a group of infectious agents which have been transmitted from the mother through the placenta. The infections include toxoplasmosis, rubella, cytomegalovirus, herpes virus, hepatitis and syphilis. The severity and nature of symptoms is determined by the type of infection.

Toriello Lacassie Droste syndrome

Toriello-Lacassie-Droste syndrome (medical condition): A very rare syndrome characterized by increased skin pigmentation, a localized absence of skin (aplasia cutis congenital) and epibulbar dermoids (a benign eye tumor).

Toriello syndrome

Toriello syndrome: A rare syndrome characterized by brachial arch defects and other abnormalities such as short stature, mental retardation and small head.

Toriello-Carey syndrome

Toriello-Carey syndrome (medical condition): A very rare syndrome characterized by abnormal brain development, various facial anomalies, heart defects and other symptoms.

Torsion dystonia

Torsion dystonia is a disease characterized by painful muscle contractions resulting in uncontrollable distortions. This specific type of dystonia is found in children, with symptoms starting around the ages of 11 or 12. It commonly begins with contractions in one general area such as an arm or a leg that continue to progress throughout the rest of the body. It takes roughly 5 years for the symptoms to completely progress to a debilitating state.

Torsion dystonia 7

Torsion dystonia 7: A rare inherited movement disorder where the patient suffers involuntary muscle contractions and distortion of body position. Usually the onset of symptoms is focused on one part of the body, usually the neck, eyes or hands.

Torsion dystonia with onset in infancy

Torsion dystonia with onset in infancy: A rare inherited movement disorder where the patient suffers involuntary muscle contractions and distortion of body position. The disorder occurs during infancy and tends to affect the legs severely and the face and arms to a lesser degree.

Torticollis keloids cryptorchidism renal dysplasia

Torticollis, keloids, cryptorchidism, renal dysplasia: A rare genetic condition characterized by undescended testes, kidney defects, torticollis and the formation of keloids which are scar-like elevations on the skin. The symptoms occur in males though females carriers can have mild symptoms.

Torticollis- familial

Torticollis, familial (medical condition): A familial neck disorder where the neck movement is limited and the head is tilted to one side.

Torulopsis

Torulopsis (medical condition): A type of yeast infection caused by Torulopsis glabrata. The fungus is often found in normal healthy skin, respiratory system, genitourinary system and gastrointestinal system and it generally only becomes a problem in weakened or immunocompromised people. They type of symptoms are determined by where and how severe the infection is.

Total anomalous pulmonary venous connection

Total anomalous pulmonary venous connection (TAPVC), also known as total anomalous pulmonary venous drainage (TAPVD) and total anomalous pulmonary venous return (TAPVR), is a rare cyanotic congenital heart defect (CHD) in which all four pulmonary veins are malpositioned and make anomalous connections to the systemic venous circulation.(Normally, pulmonary venous return carries oxygenated blood from the lungs to the left atrium where it can then be pumped to the rest of the body). A patent foramen ovale or an atrial septal defect must be present, or else the condition is fatal due to a lack of systemic blood flow.

Total Hypotrichosis- Mari type

Total Hypotrichosis, Mari type: A rare inherited form of congenital alopecia (hair loss). It occurs primarily in the Mari population in a part of Russia.
