Glossary for Breathing difficulty

  • 2-Methylbutyric Aciduria: A very rare genetic disorder where an enzyme deficiency prevents the break down of certain proteins into energy and results in a harmful accumulation of acids in the blood and body tissues. More specifically, there is a deficiency of an enzyme (2-methylbutyryl-coenzyme A dehydrogenase) needed to convert the amino acid isoleucine into energy. 2-methylbutyrylglycine levels build up in the body and may cause damage. Symptoms vary according to the degree of enzyme deficiency - can range from asymptomatic to life-threatening.

The condition is characterized by anemia and generally leads to the development of acute myelogenous leukemia. The acute form has more severe symptoms than the chronic form.
  • Acute mercury inhalation: Inhalation of mercury vapor can lead to serious symptoms and even death if sufficient quantities are inhaled. Mercury inhalation is more likely in confined or poorly ventilated spaces. Mercury from a broken thermometer can lead to symptoms if it occurs in a confined space.
  • Acute pharyngitis: A condition which is characterized by an acute inflammatory reaction of the pharynx
  • Acute respiratory distress syndrome, Infant: A breathing disorder that occurs in infants. The underdeveloped lungs fail to functioning adequately and the body becomes deprived of oxygen. The condition is more likely to affect premature infants and the greater the prematurity, the greater the risk.

The body has enough iron but the red blood cells are unable to utilize it in a normal manner and anemia results. The red blood cells become overloaded with iron and are unable to carry out their normal functions. Some forms of sideroblastic anemia are inherited but most tend to be acquired due to such things as exposure to toxins and certain drugs, leukemia, inflammatory conditions such as rheumatoid arthritis and nutritional deficiencies (e.g. copper and pyridoxine deficiency). Inherited forms usually appear in childhood whereas acquired forms usually occur in adulthood.

Animals frequently lick themselves which results in saliva sticking to the fur. Thus a person allergic to animals will often react to the fur even if it is not attached to the animal. Frequent washing of the animal may reduce symptoms. The body's immune system produces immunoglobulin E (IgE - an antibody) and histamine in response to contact with the allergen. The specific symptoms that can result can vary considerably amongst patients e.g. skin and respiratory symptoms.

The green berries are considered the most toxic part of the plant but the leaves are also poisonous but less likely to be eaten. Skin irritation can also result from skin contact with the plant.
  • Laryngeal papillomatosis: A rare disease characterized by the development of tumors in the larynx, vocal cords or respiratory tract. The disease is caused by the human papilloma virus. Symptoms will vary according to the size, location and aggressiveness of the tumor.
  • Latex allergies: When a person has an allergic reaction to latex
  • Limbic encephalitis -- neuromyotonia -- hyperhidrosis -- polyneuropathy: A rare autoimmune disorder involving excessive sweating, dysfunction central nervous system and neuromyotonia. The condition occurs when the body develops antibodies to voltage-gated potassium channels.
  • Lionfish poisoning: The Lionfish is a venomous bottom-dwelling fish which is found in the Pacific and Indian Oceans. Symptoms tend to abate after 8 to 12 hours.
  • Lisinopril -- Teratogenic Agent: There is evidence to indicate that exposure to Lisinopril during pregnancy may have a teratogenic effect on the fetus. A teratogen is a substance that can cause birth defects. The likelihood and severity of defects may be affected by the level of exposure and the stage of pregnancy that the exposure occurred at.
  • Local anaesthetic allergy: Using Local anaesthetic can cause an allergic response in some people however this is considered rare. It involves the body's immune system overreacting to the drug. The type and severity of symptoms can vary considerable though skin symptoms are the most common allergic response to drugs.
  • Lodine -- Teratogenic Agent: There is evidence to indicate that exposure to Lodine (used mainly for arthritis) during pregnancy may have a teratogenic effect on the fetus. A teratogen is a substance that can cause birth defects. The likelihood and severity of defects may be affected by the level of exposure and the stage of pregnancy that the exposure occurred at.
  • Lung cancer: Lung cancer is a disease of uncontrolled cell growth in tissues of the lung. This growth may lead to metastasis, which is the invasion of adjacent tissue and infiltration beyond the lungs. Most lung tumors are malignant.
  • Lung herniation -- congenital defect of sternum: A rare congenital disorder where a some of the lung tissues pushes through and opening in the breast bone. The mid-chest mass may change in size with inhalation and exhalation.
  • Lupine poisoning: A flowering herb which produced long clusters of flowers in various colors. It also produces flat, seed-filled pods. The seeds contain toxic chemicals (alkaloids such as lupinine, anagyrine, sparteine) which can cause poisoning if eaten in large quantities. Different species have different amounts of the toxin and some species are not toxic at all.
  • Lupus: Autoimmune disease with numerous effects on various organs and linings.
  • Lymphocyte depletion Hodgkin's disease: Hodgkin's disease is a type of cancer characterized by the abnormal proliferation of a type of white blood cell called lymphocyte. Hodgkin's lymphoma is classified into classical types and nodular lymphocyte predominant type. The nodular form tends to be more localized than the classical form. Classical Hodgkin's lymphoma is further subdivided into four subgroups depending on the cell composition of the lymphoma: nodular sclerosing, mixed cellularity, lymphocyte rich and lymphocyte depleted. The lymphocyte depleted form is the least common form of Hodgkin's disease.
  • Lymphoid interstitial pneumonia: A relatively rare form of lung disease characterized by the buildup of lymphocytes (a type of white blood cell) in the air spaces or alveoli of the lungs. The condition can affect children or adults and is frequently associated with conditions such as HIV and autoimmune conditions such as rheumatoid arthritis and Hashimoto's thyroiditis. Symptoms may develop gradually over a period of months or even years in some cases.
  • Lymphomatoid Granulomatosis: A rare, progressive blood vessel disease where nodular lesions destroy blood vessels - lungs, skin and nervous system are mainly involved.
  • Marijuana overdose: Marijuana is a relatively common recreational drug sometimes used to manage pain or stress disorders. Very large amounts have to be smoked or eaten in order to result in overdose symptoms and death is extremely unlikely. The symptoms of excessive doses are more unpleasant than dangerous.
  • Mayapple poisoning: The Mayapple is a small flowering plant which is often found growing naturally. It bears small single flowers and apple-like fruit which turns yellow when ripe. The unripe fruit and leaves contain a chemical called podophyllin which can cause poisoning if eaten. The plant is considered highly toxic and death can occur if sufficient quantities are eaten. The leaves, roots and unripe fruit are toxic but the ripe fruit is edible. The plant has been used to treat venereal warts.
  • Measles: Once common viral infection now rare due to vaccination.
  • Medium-Chain Acyl-CoA Dehydrogenase Deficiency: A rare disorder where the body lacks enzymes needed to convert some fats (medium-chain fatty acids) into energy and hence these fats build up in the body and cause damage.
  • Meige syndrome: A neurological movement disorder involving symptoms such as involuntary facial movements and eye muscle spasms.
  • Melioidosis: Bacterial infection from soil or water.
  • Meperidine -- Teratogenic Agent: There is evidence to indicate that exposure to Meperidine during pregnancy may have a teratogenic effect on the fetus. A teratogen is a substance that can cause birth defects. The likelihood and severity of defects may be affected by the level of exposure and the stage of pregnancy that the exposure occurred at.
  • Mercury poisoning: A type of heavy metal poisoning caused by excessive exposure to mercury.
