Diseases, Illnesses & Ailments Starting from Letter N

  1. Niemann-Pick Disease
    Niemann-Pick disease is classified as an autosomal recessive disorder. It primarily affects the way fats or lipids are metabolized in the body. This means that the normal process of breaking down fats within the body and the manner in which they are being utilized for daily activities is impaired. This disorder severely affects the body because it can cause excessive and unhealthy buildup of lipids or fats in the liver, bone marrow, lungs, spleen and even in the brain. There are three variants of Niemann-Pick Disease which are Types A, B and C. Classification is based on the genetic cause and on the symptoms being presented. [read more]

  2. Niemann-Pick Disease Type C
    Niemann-Pick disease Type C is classified as an autosomal recessive disorder. It mainly affects the metabolism of fats and lipids in the body. The process of fat breakdown in the body and the manner of utilizing it for daily activities is greatly affected. This disorder which impairs fat metabolism in the body causes excessive and abnormally high amounts of lipids to accumulate in the liver, bone marrow, lungs, spleen and even in the brain. Niemann-Pick Disease Type C usually occurs during the childhood stages. However, it may also manifest during infancy and adulthood. Incidence for this type of disease had been estimated to be 1 in every 150,000 individuals. Niemann-Pick Disease Type C is more common among individuals of French-Acadian descent living in Nova Scotia. [read more]

  6. Nijmegen Breakage Syndrome
    Nijmegen Breakage Syndrome or NBS is also referred to as Berlin Breakage Syndrome and Seemanova Syndrome. This condition is a rare form of disease syndrome. It is mainly characterized by chromosomal instability. Probable reason could be as a result of an abnormality or clinical defect in the Double Holliday junction DNA repair mechanism. Nijmegen Breakage Syndrome is usually manifested by several distinctive characteristics. Major clinical presentation includes microcephaly, distinct appearance and expression of the face, shortness in stature, immunodeficiency and sensitivity to radiation. Patients who are diagnosed with NBS are found to have an increased risk of having lymphoid malignancy. The name, Nijmegen Breakage Syndrome, was derived from the Dutch city, Nijmegen which was where the first description of this disease had been established. Majority of the people afflicted with NBS have origins from the West Slavic. A significant percentage live in Poland. [read more]

  8. Nocardiosis
    Nocardiosis is an infectious disease which affects the lungs or the whole body. Affectation of the lungs is termed as Pulmonary Nocardiosis while affectation of the entire body is referred to as Systemic Nocardiosis. Nocardiosis is caused primarily of an infection by bacterium of the genus Nocardia. The common forms are Nocardia asteroides and Nocardia brasiliensis. Men are more commonly affected particularly those whose immune systems are already compromised. Among patients afflicted with brain infection, rate of mortality goes beyond 80%. Among the other forms, mortality rate is at 50% even with therapy. [read more]

  9. Nocturia
    Nocturia pertains to a condition characterized by excessive urination at night. Patients with nocturia constantly need to get up during the night to urinate and may thus suffer from sleep distortions. While it can occur in children and younger adults, nocturia more typically affects the elderly. [read more]

  10. Nocturnal Enuresis
    Nocturnal Enuresis also known as bedwetting is involuntary urination while asleep after the age at which bladder control would normally be anticipated. Primary Nocturnal Enuresis (PNE) is during a child has not yet stayed dry on a regular basis. Secondary Nocturnal Enuresis is when a child or adult starts wetting again after having stayed dry. [read more]

  11. Nodules, Thyroid
    Thyroid Nodules is a condition whereby there is one or more nodules that develop within the person's gland. It is usually a water-filled lump and is usually noncancerous but develops and become large to press on the person's windpipe. [read more]

  12. Noise Induced Deafness
    Noise Induced Deafness may be a full or partial reduction in the ability to determine and understand sounds. This condition is usually caused by a wide range of environmental factors. Sound waves have varying frequencies and amplitudes. A person who has lost his ability to detect some frequencies and some low-amplitude sounds which should normally be detected is a characteristic of this condition. Whenever humans are exposed to harmful noise and sounds that are too loud and last a long time, the sensitive structures found in the inner ear may be damaged thereby causing noise-induced hearing loss (NIHL) or Noise Induced Deafness. These sensitive structures which are also called hair cells, are small sensory cells found in the inner ear. They convert sound energy into electrical signals which travel towards the brain. Once the hair cells are damaged, they cannot grow back. [read more]

  13. Noma
    Noma came from the Greek term numein which means to devour. This condition is also referred to as Cancrum Oris or Gangrenous Stomatitis. Noma is a form of gangrenous disease which leads to destruction of the tissues of the face. Commonly affected areas are the cheeks and mouth. Noma has significantly high rates of morbidity and mortality. A rough estimate of 80% had been reported. Children under the age of 12 years who are living in the poor countries of Africa have high predisposition to this disease. Asian children as well as several countries within South America also present a certain degree of predisposition. Majority of the children who develop Noma are around the ages 2 to 6 years old. An estimated number of 500,000 individuals had developed this disease according to the WHO. 100,000 new cases arise every year. [read more]

  14. Non-Hodgkin Lymphoma
    Non-Hodgkin Lymphoma or NHL is characterized by a certain group of cancers which arise from lymphocytes. NHL has distinctive clinical presentation from Hodgkin Lymphoma based on its pathology and epidemiology. It is also different from Hodgkin Lymphoma based on the commonly involved sites, clinical behavior and medical treatment. Diseases associated with non-Hodgkin Lymphomas presents diversity. The course of the diseases varies as well as the treatments. Prognoses for recovery among patients are also variable. Non-Hodgkin lymphoma usually develops in the spleen, lymph nodes and tonsils or in other organs which are related to the lymphatic system. Majority of the cases initially present as infiltration of lymph nodes. However, there are some subtypes which are restricted to other organs of the lymphatic system. [read more]

  15. Non-ketotic Hyperglycinemia
    Non-ketotic Hyperglycinemia (NKH) more commonly known as Glycine encephalopathy is an autosomal recessive metabolic disorder. Clinical presentation shows abnormally high level of Glycine which is a form of amino acid. This works as a neurotransmitter or chemical messenger in the brain. Primary cause of non-ketotic hyperglycinemia is insufficient amounts of the enzyme which normally metabolizes the amino acid, glycine, in the body. Shortage or lack of this enzyme allows abnormally high levels of glycine to accumulate in the organs and tissues. Particularly affected is the brain which leads to complicated medical problems.

  16. Non-Small Cell Lung Cancer
    The non-small cell lung cancers are taken as one group because their prognoses for recovery and treatments are basically the same. There are three main sub-types of non-small cell lung cancer namely adenocarcinoma, squamous cell lung carcinoma and large cell lung carcinoma. Squamous cell lung carcinoma accounts for 31.1% of the cases. This type of non-small cell lung carcinoma usually starts in close proximity to central bronchus. Development of cavities and necrotic tissues within the center of the cancer site is a major and common finding. Squamous cell lung cancers which are well-differentiated often develop and spread at a slower pace compared to other cancer types. Adenocarcinoma accounts for 29.4% of the cases. This type usually starts in peripheral lung tissue. Majority of the cases are related to smoking. Adenocarcinoma is the most common type of lung cancer among non-smokers. Bronchioloalveolar carcinoma is another subtype. Women who are non-smokers are more predisposed to this cancer form and responses to treatment vary. Large cell lung carcinoma accounts for 10.7% of lung cancers. This type grows rapidly and develops near the lung surface. It is poorly differentiated most of the time and has a tendency to metastasize during its early stages. [read more]

  17. Non-Specific Urethritis
    Non-Specific Urethritis (shortened as NSU) is a type of urethritis characterized by inflammation of the urethra that cannot be attributed to Chlamydia, gonorrhea, or any infectious cause. Most cases of non-specific urethritis are sexually transmitted, while some have no evidence of infections at all. [read more]

  18. Nonalcoholic Fatty Liver Disease
    Nonalcoholic fatty liver disease or NAFLD for brevity, is a medical condition where there is are presence of conditions involving the liver of the person who does not drink or just drink a little. Liver scarring and liver damaging inflammation are the result of a type of NAFLD which is called th e Nonalcoholic Steatohepatitis or NASH. [read more]

  19. Nonalcoholic Steatohepatitis
