Hyper-IgM Immunodeficiency Syndrome
|
D053306 |
[Hyper-IgM immunodeficiency subtype resulting from mutation in the gene encoding activation-induced CYTIDINE DEAMINASE.
, A rare inherited immunodeficiency syndrome characterized by normal or elevated serum IMMUNOGLOBULIN M levels with absence of IMMUNOGLOBULIN G; IMMUNOGLOBULIN A; and IMMUNOGLOBULIN E. It results in a profound susceptibility to BACTERIAL INFECTIONS and an increased susceptibility to OPPORTUNISTIC INFECTIONS. Several subtypes of hyper-IgM immunodeficiency syndrome exist depending upon the location of genetic mutation.
, Hyper-IgM immunodeficiency subtype resulting from mutation in the gene encoding CD40 ANTIGEN.

Hyperacusis
|
D012001 |
[An abnormally disproportionate increase in the sensation of loudness in response to auditory stimuli of normal volume. COCHLEAR DISEASES; VESTIBULOCOCHLEAR NERVE DISEASES; FACIAL NERVE DISEASES; STAPES SURGERY; and other disorders may be associated with this condition.

|
Hyperaldosteronism
|
D006929 |
[Primary hyperaldosteronism caused by the excess production of ALDOSTERONE by an ADENOMA of the ZONA GLOMERULOSA or CONN ADENOMA.
, A condition caused by the overproduction of ALDOSTERONE. It is characterized by sodium retention and potassium excretion with resultant HYPERTENSION and HYPOKALEMIA.

Hyperalgesia
|
D006930 |
[An increased sensation of pain or discomfort produced by minimally noxious stimuli due to damage to soft tissue containing NOCICEPTORS or injury to a peripheral nerve.

|
Hyperammonemia
|
D022124 |
[Elevated level of AMMONIA in the blood. It is a sign of defective CATABOLISM of AMINO ACIDS or ammonia to UREA.
] |
|
Hyperamylasemia
|
D034321 |
[A benign condition in which the circulating AMYLASES are of high molecular masses, macroamylases. Macroamylases are amylase-plasma protein complexes, usually with immunoglobulins. Macroamylases cannot be cleared by the renal glomeruli.
, A condition with abnormally elevated level of AMYLASES in the serum. Hyperamylasemia due to PANCREATITIS or other causes may be differentiated by identifying the amylase isoenzymes.

|
Hyperandrogenism
|
D017588 |
[A condition caused by the excessive secretion of ANDROGENS from the ADRENAL CORTEX; the OVARIES; or the TESTES. The clinical significance in males is negligible. In women, the common manifestations are HIRSUTISM and VIRILISM as seen in patients with POLYCYSTIC OVARY SYNDROME and ADRENOCORTICAL HYPERFUNCTION.

|
Hyperargininemia
|
D020162 |
[A rare autosomal recessive disorder of the urea cycle. It is caused by a deficiency of the hepatic enzyme ARGINASE. Arginine is elevated in the blood and cerebrospinal fluid, and periodic HYPERAMMONEMIA may occur. Disease onset is usually in infancy or early childhood. Clinical manifestations include seizures, microcephaly, progressive mental impairment, hypotonia, ataxia, spastic diplegia, and quadriparesis. (From Hum Genet 1993 Mar;91(1):1-5; Menkes, Textbook of Child Neurology, 5th ed, p51)

|
Hyperbaric Oxygenation
|
D006931 |
[The therapeutic intermittent administration of oxygen in a chamber at greater than sea-level atmospheric pressures (three atmospheres). It is considered effective treatment for air and gas embolisms, smoke inhalation, acute carbon monoxide poisoning, caisson disease, clostridial gangrene, etc. (From Segen, Dictionary of Modern Medicine, 1992). The list of treatment modalities includes stroke.

|
Hyperbilirubinemia
|
D006932 |
[A condition characterized by an abnormal increase of BILIRUBIN in the blood, which may result in JAUNDICE. Bilirubin, a breakdown product of HEME, is normally excreted in the BILE or further catabolized before excretion in the urine.
] |
|
Hyperbilirubinemia, Hereditary
|
D006933 |
[Inborn errors of bilirubin metabolism resulting in excessive amounts of bilirubin in the circulating blood, either because of increased bilirubin production or because of delayed clearance of bilirubin from the blood.
] |
|
Hyperbilirubinemia, Neonatal
|
D051556 |
[Accumulation of BILIRUBIN, a breakdown product of HEME PROTEINS, in the BLOOD during the first weeks of life. This may lead to NEONATAL JAUNDICE. The excess bilirubin may exist in the unconjugated (indirect) or the conjugated (direct) form. The condition may be self-limiting (PHYSIOLOGICAL NEONATAL JAUNDICE) or pathological with toxic levels of bilirubin.

|
Hypercementosis
|
D006936 |
[A regressive change of teeth characterized by excessive development of secondary cementum on the tooth surface. It may occur on any part of the root, but the apical two-thirds are most commonly affected. (Dorland, 27th ed)

|
Hypercholesterolemia
|
D006937 |
