FALDH deficiency
|
|
FALDH deficiencyAlso known as the Sjogren-Larsson syndrome, this is a genetic (inherited) disease usually characterized by a triad of clinical findings consisting of ichthyosis (thickened fish-like skin), spastic paraplegia (spasticity of the legs) and mental retardation.
RELATED TERMS--------------------------------------
Syndrome
A grouping of signs and symptoms, based on their frequent co-occurrence, that may suggest a common underlying pathogenesis, course, familial pattern, or treatment selection.
Genetic
Hereditary. Having to do with the genes.
Disease
Illness or sickness often characterized by typical patient problems (symptoms) and physical findings (signs). Disruption sequence: The events that occur when a fetus that is developing normally is subjected to a destructive agent such as the rubella (German measles) virus.
Triad
Triad is a prescription or over-the-counter drug which is (or once was) approved in the United States and possibly in other countries. Active ingredient(s): acetaminophen; butalbital; caffeine.
Clinical
That which can be observed in patients. Research that uses patients to test new treatments, as opposed to laboratory testing or research in animals.
Ichthyosis
An inherited skin disorder that produces dry, rough, scaly skin.
Paraplegia
Paraplegiai nvolves a loss of sensation and movement in the legs and in part or all of the trunk. This varies according to the level of the injury. Generally, the lower the injury, the less the loss of movement and sensation. Paraplegia usually results from an injury to the spinal cord in the mid and lower back.
Retardation
Delay or halt of any process such as mental or physical development.
SIMILAR TERMS--------------------------------------
PREVIOUS AND NEXT TERMS--------------------------------------
Fahrenheit
Thermometer scale in which the freezing point of water is 32°F and the boiling point of water 212°F. The Fahrenheit scale is still obstinately in use in the US. This anachronism requires conversion from Centigrade (°C) to Fahrenheit (°F), and vice versa. One degree °C = (5/9)(°F - 32). One degree °F = (9/5)(°C) + 32.
Failure to thrive (FTT)
Refers to a child whose physical growth is significantly less than that of peers. There is no official consensus on what constitutes failure to thrive (FTT). It usually refers to a child whose growth is below the 3rd or 5th percentiles for their age or whose growth has fallen off precipitously and crossed two major growth percentiles (for example, from above the 75th percentile to below the 25th percentile). Failure to thrive in early infancy sometimes results in death, and in older infancy or childhood is an important marker for underlying disease. Causes of failure to thrive are probably many, including unrecognized food allergies leading to refusal of food and vomiting, undiagnosed metabolic disorders, and disease.
Failure, adrenal
A condition in which the adrenal glands do not produce enough of the adrenal hormones that control important functions such as blood pressure. The adrenal glands sit on top of the kidneys. The adrenal is made up of an outer layer (the cortex) and an inner portion (the medulla). The adrenal glands produce hormones that help control the heart rate, blood pressure, the way the body uses food, and other vital functions. The adrenal cortex secretes steroid (cortisone-related) hormones and mineralocortoids that regulate the levels of minerals such as sodium and potassium in the blood.
Fainting (syncope)
Partial or complete loss of consciousness with interruption of awareness of oneself and ones surroundings. When the loss of consciousness is temporary and there is spontaneous recovery, it is referred to as syncope or, in nonmedical quarters, fainting. Syncope accounts for one in every 30 visits to an emergency room. It is pronounced sin-ko-pea. Syncope is due to a temporary reduction in blood flow and therefore a shortage of oxygen to the brain. This leads to lightheadedness or a "black out" episode, a loss of consciousness. Temporary impairment of the blood supply to the brain can be caused by heart conditions and by conditions that do not directly involve the heart.
Falciparum malaria
The most dangerous type of malaria. Red blood cells infected with the parasite tend to sludge and form microinfarctions (small areas of dead tissue due to lack of oxygen) in capillaries in the brain, liver, adrenal gland, intestinal tract, kidneys, lungs, and other organs. Treatment is in a hospital setting, using intravenous medications.
FALDH deficiency
False labor
Intermittent non-productive muscular contractions of the womb (uterus) during pregnancy, most commonly in the last two months before full term. These contractions are non-productive in the sense that they do not produce any flattening (effacement) or dilation (opening up) of the cervix.
False negative
A result that appears negative but fails to reveal a situation. An example of a false negative: a particular test designed to detect cancer of the toenail is negative but the person has toenail cancer.
False positive
A result that is erroneously positive when a situation is normal. An example of a false positive: a particular test designed to detect cancer of the toenail is positive but the person does not have toenail cancer.
False rib
One of the last 5 pairs of ribs. A rib is said to be "false" if it does not attach to the sternum (the breast bone). All 12 pairs of ribs attach to the building blocks of the spine (vertebrae) in the back. The 12 pairs of ribs consist of: True ribs: The first seven ribs attach to the sternum (the breast bone) in the front and are known as true (or sternal) ribs. False ribs: The lower five ribs do not directly connect to the sternum and are known as false ribs. The upper three false ribs connect to the costal cartilages of the ribs just above them. The last two false ribs, however, usually have no ventral attachment (no anchor at all in front) and are called floating, fluctuating or vertebral ribs.
False vocal cord
A fold of mucous membrane covering muscle in the larynx. The false vocal cord separates the ventricle of the larynx from the vestibule of the larynx. Also called the false vocal fold.
