Default principal diagnosis: inpatient Yes · outpatient Yes

Clinical InformationClinical

  • Hydrops Fetalis

    abnormal accumulation of serous fluid in two or more fetal compartments, such as skin; pleura; pericardium; placenta; peritoneum; amniotic fluid. general fetal edema may be of non-immunologic origin, or of immunologic origin as in the case of erythroblastosis fetalis.

  • Altitude Sickness

    multiple symptoms associated with reduced oxygen at high altitude.

  • Aryl Hydrocarbon Receptor Nuclear Translocator

    aryl hydrocarbon receptor nuclear translocator is a basic helix-loop-helix motif containing protein that forms a complex with dioxin receptor. the complex binds xenobiotic regulatory elements and activates transcription of a variety of genes including udp glucuronosyltransferase. ahr nuclear translocator is also a subunit of hypoxia-inducible factor 1.

  • Cell Hypoxia

    a condition of decreased oxygen content at the cellular level.

  • Fetal Hypoxia

    deficient oxygenation of fetal blood.

  • Hypoxia

    sub-optimal oxygen levels in the ambient air of living organisms.

  • Hypoxia, Brain

    a reduction in brain oxygen supply due to anoxemia (a reduced amount of oxygen being carried in the blood by hemoglobin), or to a restriction of the blood supply to the brain, or both. severe hypoxia is referred to as anoxia and is a relatively common cause of injury to the central nervous system. prolonged brain anoxia may lead to brain death or a persistent vegetative state. histologically, this condition is characterized by neuronal loss which is most prominent in the hippocampus; globus pallidus; cerebellum; and inferior olives.

  • Hypoxia-Inducible Factor 1

    a basic helix-loop-helix transcription factor that plays a role in apoptosis. it is composed of two subunits: aryl hydrocarbon receptor nuclear translocator and hypoxia-inducible factor 1, alpha subunit.

  • Hypoxia-Inducible Factor 1, alpha Subunit

    hypoxia-inducible factor 1, alpha subunit is a basic helix-loop-helix transcription factor that is regulated by oxygen availability and is targeted for degradation by vhl tumor suppressor protein.

  • Hypoxia-Inducible Factor-Proline Dioxygenases

    dioxygenase enzymes that specifically hydroxylate a proline residue on the hypoxia-inducible factor 1, alpha subunit. they are oxygen-dependent enzymes that play an important role in mediating cellular adaptive responses to hypoxia.

  • Hypoxia-Ischemia, Brain

    a disorder characterized by a reduction of oxygen in the blood combined with reduced blood flow (ischemia) to the brain from a localized obstruction of a cerebral artery or from systemic hypoperfusion. prolonged hypoxia-ischemia is associated with ischemic attack, transient; brain infarction; brain edema; coma; and other conditions.

  • Tumor Hypoxia

    hypoxic conditions in tumor cells due to the tumor outgrowing its blood supply. it is associated with increased metastasis and resistance to radiotherapy and drug therapy.

  • Acidosis

    a pathologic condition of acid accumulation or depletion of base in the body. the two main types are respiratory acidosis and metabolic acidosis, due to metabolic acid build up.

  • Acidosis, Lactic

    acidosis caused by accumulation of lactic acid more rapidly than it can be metabolized. it may occur spontaneously or in association with diseases such as diabetes mellitus; leukemia; or liver failure.

  • Acidosis, Renal Tubular

    a group of genetic disorders of the kidney tubules characterized by the accumulation of metabolically produced acids with elevated plasma chloride, hyperchloremic metabolic acidosis. defective renal acidification of urine (proximal tubules) or low renal acid excretion (distal tubules) can lead to complications such as hypokalemia, hypercalcinuria with nephrolithiasis and nephrocalcinosis, and rickets.

  • Acidosis, Respiratory

    respiratory retention of carbon dioxide. it may be chronic or acute.

  • Diabetic Ketoacidosis

    a life-threatening complication of diabetes mellitus, primarily of type 1 diabetes mellitus with severe insulin deficiency and extreme hyperglycemia. it is characterized by ketosis; dehydration; and depressed consciousness leading to coma.

  • Hypoaldosteronism

    a congenital or acquired condition of insufficient production of aldosterone by the adrenal cortex leading to diminished aldosterone-mediated synthesis of na(+)-k(+)-exchanging atpase in renal tubular cells. clinical symptoms include hyperkalemia, sodium-wasting, hypotension, and sometimes metabolic acidosis.

  • Altitude

    a vertical distance measured from a known level on the surface of a planet or other celestial body.

  • Fetal Blood

    blood of the fetus. exchange of nutrients and waste between the fetal and maternal blood occurs via the placenta. the cord blood is blood contained in the umbilical vessels (umbilical cord) at the time of delivery.

  • Oxygen

    an element with atomic symbol o, atomic number 8, and atomic weight [15.99903; 15.99977]. it is the most abundant element on earth and essential for respiration.

  • Compensated Metabolic Acidosis|Compensated metabolic alkalosis

  • Diabetic Ketoacidosis|DKA|DKA|Elevated ketones/Diabetic Ketoacidosis

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
