Hemoptysis

Hemoptysis in American English, spelled haemoptysis in British English, is the act of coughing up blood or blood-stained mucus from the bronchi, larynx, trachea, or lungs. This can occur with lung cancer, infections such as tuberculosis, bronchitis, or pneumonia, and certain cardiovascular conditions. Hemoptysis is considered massive if there is more than 300 mL (11 imp fl oz; 10 US fl oz) of blood lost in 24 hours. In such cases, the primary danger comes from choking, rather than blood loss.

Differential diagnosis

There are many conditions involving hemoptysis, including but not limited to bronchitis and pneumonia most commonly, but also lung cancers (in smokers, hemoptysis is often persistent), aspergilloma, tuberculosis, bronchiectasis, coccidioidomycosis, pulmonary embolism, pneumonic plague, and cystic fibrosis. Rarer causes include hereditary hemorrhagic telangiectasia (HHT or Rendu-Osler-Weber syndrome), Goodpasture's syndrome, and granulomatosis with polyangiitis. In children, hemoptysis is commonly caused by the presence of a foreign body in the airway. The condition can also result from over-anticoagulation from treatment by drugs such as warfarin.

Hemoptysis (band)

Hemoptysis is an American extreme metal band, named after the medical term for the coughing up of blood. Founded in 2007, the band's music is built around a solid core of old-school thrash/death metal. However, they incorporate strong European elements of black metal and melodic death metal, as well as traditional metal. 2011 has proven a productive year for the Hemoptysis, as they have released their full length, debut album, Misanthropic Slaughter, signed a European distribution deal with Rock It Up Records, and appear on Heavy Metal Magazine's Gates Volume 1 – Ascension soundtrack.

History

Formation and Who Needs a Shepherd? (2007–2009)

Masaki Murashita (guitar/vocals) and Travis Thune (drums) were introduced by way of a mutual friend in February 2007. Bass player Sunao Arai, who had practiced with the band for several months, became an official member in February 2008. Brian Bieganski joined the band as lead guitarist, later that year. While they originally practiced with a singer, Masaki eventually stepped up as the band's front man. In naming the band, Travis' wife, a pharmacist specializing in infectious diseases, suggested Hemoptysis, a medical term meaning the coughing up of blood.
