Diseases, Illnesses & Ailments Starting from Letter B

  1. Bronchitis
    Bronchitis is a condition that occurs when the inner walls lining the main airways of the lungs become inflamed; usually happening after a previous respiration infection like colds. [read more]

  2. Bronchitis, Chronic
    Chronic bronchitis is the inflammation, or irritation, of the airways in the lungs. Airways are the tubes in the lungs where air passes through. They are also known as bronchial tubes. When the airways are irritated, thick mucus forms inside of them. The mucus plugs up the airways and makes it hard for the person to get air into your lungs. Symptoms of chronic bronchitis include a cough that produces mucus (sometimes called sputum), breathing difficulties, and a feeling of tightness in the chest. [read more]

  3. Bronchopulmonary Dysplasia
    Bronchopulmonary dysplasia involves the abnormal development of lung tissue. It is marked by inflammation and scarring in the lungs. It occurs most often in premature babies, who are born with underdeveloped lungs. "Broncho" is the name of the airways (the bronchial tubes) through which the oxygen we breathe travels into the lungs. "Pulmonary" refers to the lungs' tiny air sacs (alveoli), where carbon dioxide and oxygen are exchanged. "Dysplasia" means abnormal changes in the organization or structure of a group of cells. The cell changes in BPD occur in the smaller airways and lung alveoli, making breathing difficult and causing problems with lung function. [read more]

  4. Bronze Diabetes
    Bronze diabetes, or hemachromatosis, is a kind of diabetes caused by an overload of iron deposits in the body tissues. Without treatment, iron overload may cause complications and eventually lead to organ failure. [read more]

  5. Brown Syndrome
    Brown Syndrome is a rare eye disorder marked by defects in eye movements. This disorder may be present at birth (congenital) or may occur as the due to another underlying disorder (acquired). Muscles control eye movements and activities. Some of these muscles turn the eyeball up and down, move the eyeball from side to side, or let the eyeball to rotate slightly in its socket. The superior oblique tendon sheath of the superior oblique is the muscle that surrounds the eyeball. The symptoms of Brown Syndrome are due to abnormalities of this tendon sheath including shortening, thickening, or inflammation. This leads to the inability to move the affected eye upward. [read more]

  6. Brown-Squard Syndrome
    Brown-S?quard syndrome, also known as Brown-S?quard's hemiplegia and Brown-S?quard's paralysis, is a loss of motricity (paralysis and ataxia) and sensation as a result of the lateral hemisection of the spinal cord. Other names for the syndrome are crossed hemiplegia, hemiparaplegic syndrome, hemiplegia et hemiparaplegia spinalis and spinal hemiparaplegia. It is an incomplete spinal cord lesion characterized by a clinical picture reflecting hemisection of the spinal cord, often in the cervical cord region. It was initially described in the 1840s after Dr. Charles Edouard Brown-Sequard sectioned one half of the spinal cord. It is a rare syndrome, made up of ipsilateral hemiplegia with contralateral pain and temperature sensation deficits because of the crossing of the fibers of the spinothalamic tract. [read more]

  7. Brucellosis
    Brucellosis, also known as undulant fever, undulating fever, or Malta fever, is a zoonosis (infectious disease transmitted from animals to humans) caused by bacteria of the genus Brucella. It is generally a disease of domestic animals (goats, pigs, cattle, dogs, etc) and humans and has a worldwide distribution, mostly now in developing countries. [read more]

  8. Brugada Syndrome
    The Brugada syndrome is a genetic disease that is marked by abnormal electrocardiogram (ECG) findings and an increased risk of sudden cardiac death. It is also known as Sudden Unexpected Death Syndrome (SUDS), and is the most commonly found cause of sudden death in young men without known underlying cardiac disease in Thailand and Laos. Although the ECG findings of Brugada syndrome were first reported among survivors of cardiac arrest in 1989, it was only in 1992 that the Brugada brothers recognised it as a distinct clinical entity, causing sudden death by resulting to ventricular fibrillation (a lethal arrhythmia) in the heart.

  9. Bruton Agammaglobulinemia
    Bruton agammaglobulinemia was the first immunodeficiency disease to be described. Colonel Ogden Bruton noted in 1952 the absence of immunoglobulins in a young male with a history of pneumonias and other bacterial sinopulmonary infections. Bruton was also the first physician to furnish specific immunotherapy for this X-linked disorder by administering intramuscular injections of immunoglobulin G (IgG). The patient improved but died of chronic pulmonary disease in his fourth decade of life. This disorder is now formally known as X-linked agammaglobulinemia (XLA), and the gene defect has been mapped to the gene that codes for Bruton tyrosine kinase (Btk) at band Xq21.3. The BTK gene is big and consists of 19 exons that encode the 659 amino acids that form the Btk cytosolic tyrosine kinase. Mutations can happen in any area of the gene. Btk is needed for the proliferation and differentiation of B lymphocytes. In the absence of working Btk, mature B cells that express surface immunoglobulin and the marker CD19 are few to absent. The lack of CD19 is readily detected with fluorocytometric assays, and this finding usually easily confirms the diagnosis of XLA in a male. As Bruton originally described, XLA shows itself as pneumonias and other bacterial sinopulmonary infections in 80% of cases. Such infections that start in male infants as maternal IgG antibodies, acquired transplacentally, are lost. Thus, XLA is most often diagnosed when unusually severe or recurrent sinopulmonary infections occur in a male infant younger than 1 year. [read more]

  10. Bruxism
    Bruxism is the medical term used in referring to gnashing, grinding or clenching of teeth; usually affecting children and adults alike. Individuals with bruxism clench teeth at daytime usually when anxious or stressed. Long-term bruxism leads to unpleasant conditions such as jaw problems, damaged teeth, and headache. [read more]

  11. Bubonic Plague
    The bubonic plague, also known as bubonic fever, is the best-known variant of the deadly infectious disease caused by the enterobacteria Yersinia pestis (Pasteurella pestis). The epidemiological use of the term ?plague? is currently applied to bacterial infections that cause buboes, although historically the medical use this term has been applied to pandemic infections in general. [read more]

  12. Budd-Chiari Syndrome
    In medicine (gastroenterology and hepatology), Budd-Chiari syndrome is the clinical picture resulted from occlusion of the hepatic vein or inferior vena cava. It presents with the classical triad of abdominal pain, ascites and hepatomegaly. Some examples of occlusion include thrombosis of hepatic veins and membranous webs in the inferior vena cava. The syndrome can be acute, fulminant, chronic, or asymptomatic. It takes place in 1 out of 100,000 individuals and is more common in females. Some 10-20% also have a sort of obstruction of the portal vein. [read more]

  13. Buerger's Disease
    Buerger's disease, also known as thromboangiitis obliterans, is a rare disease of the arteries and veins in the arms and legs. Buerger's disease is marked by a combination of inflammation and clots in the blood vessels, which impairs blood flow. This eventually causes damage or destroys tissues and may lead to infection and gangrene. Buerger's disease typically begins in the hands and feet and may progress to affect larger areas of the limbs. Buerger's disease is uncommon in the United States, but is more common in the Middle East and Far East. Buerger's disease most commonly affects males between ages 20 and 40, though it's becoming more common in women. Basically everyone diagnosed with Buerger's disease smokes cigarettes or uses other forms of tobacco. Quitting all forms of tobacco is the only way to stop Buerger's disease from developing. For those who don't quit, amputation of all or part of a limb may ultimately be required. [read more]

  14. Bulging Disks
    A bulging disk is a medical condition in which the lower back area suffers intense pain when a disk enters a crevice in the spine. Disks are the soft tissues that serve as cushions of the spine. [read more]

  15. Bulimia Nervosa
    Bulimia nervosa, more commonly known as bulimia or "mia", is an eating disorder in which the subject engages in recurrent binge eating followed by feelings of guilt, depression, and self-condemnation. The sufferer will then take part in compensatory behaviors to make up for the excessive eating, which are referred to as "purging". Purging can take the form of fasting, vomiting, using of laxatives, enemas, diuretics or other medications, or overexercising. [read more]

  16. Bullous pemphigoid
    Bullous pemphigoid (BP) is a skin disorder that is characterized by the chronic blistering of the skin. This condition ranges from the mildly itchy welts on the skin to more severe infection and blisters, and may affect a particular area of the body or spread all other, depending on the severity. This medical condition affects mostly elderly individuals but can also be seen on people of different ages. [read more]

  17. Bundle Branch Block

  19. Bunyavirus
    Bunyavirus is a type of virus which causes infection that results damage to the various organs of the person due to a viral infection carried by the Bunyaviridae which may be passed by mosquito bites. [read more]

  20. Burkitt's lymphoma
    Burkitt's lymphoma is categorized as a highly uncommon type of a Non-Hodgkin Lymphoma (NHL). This medical condition commonly affects children than in adults and is known to be a very aggressive kind of B-cell lymphoma that typically involves body parts other than the lymph nodes. However, in spite of its rapid-growing nature, Burkitt's lymphoma is usually very curable with the availability of modern intensive therapies. [read more]
