All individuals in MESHD

Label	Id	Description
Nicolau Syndrome	D065148	[An uncommon complication of INTRAMUSCULAR INJECTION leading to variable degrees of necrosis of skin and underlying tissue.]
Nidovirales Infections	D030341	[Infections with viruses of the order NIDOVIRALES. The concept includes ARTERIVIRUS INFECTIONS and CORONAVIRIDAE INFECTIONS.]
Niemann-Pick Disease, Type A	D052536	[The classic infantile form of Niemann-Pick Disease, caused by mutation in SPHINGOMYELIN PHOSPHODIESTERASE. It is characterized by accumulation of SPHINGOMYELINS in the cells of the MONONUCLEAR PHAGOCYTE SYSTEM and other cell throughout the body leading to cell death. Clinical signs include JAUNDICE, hepatosplenomegaly, and severe brain damage.]
Niemann-Pick Disease, Type B	D052537	[An allelic disorder of TYPE A NIEMANN-PICK DISEASE, a late-onset form. It is also caused by mutation in SPHINGOMYELIN PHOSPHODIESTERASE but clinical signs involve only visceral organs (non-neuropathic type).]
Niemann-Pick Disease, Type C	D052556	[An autosomal recessive lipid storage disorder that is characterized by accumulation of CHOLESTEROL and SPHINGOMYELINS in cells of the VISCERA and the CENTRAL NERVOUS SYSTEM. Type C (or C1) and type D are allelic disorders caused by mutation of the NPC1 gene, which encodes a protein that mediates intracellular cholesterol transport from LYSOSOMES. Clinical signs include hepatosplenomegaly and chronic neurological symptoms. Type D is a variant in people with a Nova Scotia ancestry.]
Niemann-Pick Diseases	D009542	[A group of autosomal recessive disorders in which harmful quantities of lipids accumulate in the viscera and the central nervous system. They can be caused by deficiencies of enzyme activities (SPHINGOMYELIN PHOSPHODIESTERASE) or defects in intracellular transport, resulting in the accumulation of SPHINGOMYELINS and CHOLESTEROL. There are various subtypes based on their clinical and genetic differences.]
Night Blindness	D009755	[Failure or imperfection of vision at night or in dim light, with good vision only on bright days. (Dorland, 27th ed)]
Night Terrors	D020184	[A disorder characterized by incomplete arousals from sleep associated with behavior suggesting extreme fright. This condition primarily affects children and young adults and the individual generally has no recall of the event. Episodes tend to occur during stage III or IV. SOMNAMBULISM is frequently associated with this condition. (Adams et al., Principles of Neurology, 6th ed, p391)]
Nijmegen Breakage Syndrome	D049932	[A chromosome instability syndrome resulting from a defective response to DNA double-strand breaks. In addition to characteristic FACIES and MICROCEPHALY, patients have a range of findings including RADIOSENSITIVITY, immunodeficiency, increased cancer risk, and growth retardation. Causative mutations occur in the NBS1 gene, located on human chromosome 8q21. NBS1 codes for nibrin, the key regulator protein of the R/M/N (RAD50/MRE11/NBS1) protein complex which senses and mediates cellular response to DNA DAMAGE caused by IONIZING RADIATION.]
No-Reflow Phenomenon	D054318	[Markedly reduced or absent REPERFUSION in an infarct zone following the removal of an obstruction or constriction of an artery.]
Nocardia Infections	D009617	[Infections with bacteria of the genus NOCARDIA.]
Nociceptive Pain	D059226	[Dull or sharp aching pain caused by stimulated NOCICEPTORS due to tissue injury, inflammation or diseases. It can be divided into somatic or tissue pain and VISCERAL PAIN.]
Nocturia	D053158	[Frequent URINATION at night that interrupts sleep. It is often associated with outflow obstruction, DIABETES MELLITUS, or bladder inflammation (CYSTITIS).]
Nocturnal Enuresis	D053206	[Involuntary discharge of URINE during sleep at night after expected age of completed development of urinary control.]
Nocturnal Myoclonus Syndrome	D020189	[Excessive periodic leg movements during sleep that cause micro-arousals and interfere with the maintenance of sleep. This condition induces a state of relative sleep deprivation which manifests as excessive daytime hypersomnolence. The movements are characterized by repetitive contractions of the tibialis anterior muscle, extension of the toe, and intermittent flexion of the hip, knee and ankle. (Adams et al., Principles of Neurology, 6th ed, p387)]
Nocturnal Paroxysmal Dystonia	D020183	[A parasomnia characterized by paroxysmal episodes of choreoathetotic, ballistic, dystonic movements, and semipurposeful activity. The episodes occur during non-rapid eye movement sleep and typically recur several times per night. (Neurology 1992 Jul;42(7 Suppl 6):61-67; Adams et al., Principles of Neurology, 6th ed, p391)]
Nodding Syndrome	D064128	[Unexplained neurologic condition characterized by episodes of atonic seizures, convulsions or staring spells with further cognitive decline.]
Noma	D009625	[A severe gangrenous process occurring predominantly in debilitated and malnourished children, especially in underdeveloped countries. It typically begins as a small vesicle or ulcer on the gingiva that rapidly becomes necrotic and spreads to produce extensive destruction of the buccal and labial mucosa and tissues of the face, which may result in severe disfigurement and even death. Various bacteria have been implicated in the etiology. (Dorland, 27th ed)]
Non-Filarial Lymphedema	D062846	[A form of elephantiasis caused by soil particles which penetrate the skin of the foot. It is limited to tropical regions with soils of high volcanic content.]
Non-ST Elevated Myocardial Infarction	D000072658	[A myocardial infarction that does not produce elevations in the ST segments of the ELECTROCARDIOGRAM. ST segment elevation of the ECG is often used in determining the treatment protocol (see also ST Elevation Myocardial Infarction).]
