Hemoptysis is the coughing up of blood or blood-stained mucus from the bronchi, larynx, trachea, or lungs. In other words, it is the airway bleeding. This can occur with lung cancer, infections such as tuberculosis, bronchitis, or pneumonia, and certain cardiovascular conditions. Hemoptysis is considered massive at 300 mL (11 imp fl oz; 10 US fl oz). In such cases, there are always severe injuries. The primary danger comes from choking, rather than blood loss. Diagnosis
Past history, history of present illness, family historyhistory of tuberculosis, bronchiectasis, chronic bronchitis, mitral stenosis, etc. history of cigarette smoking, occupational diseases by exposure to silica dust, etc. Blood
duration, frequency, amount
Amounts of blood: large amounts of blood, or is there blood-streaked sputum
Probable source of bleeding: Is the blood coughed up, or vomited? Bloody sputum
color, characters: blood-streaked, fresh blood, frothy pink, bloody gelatinous. Accompanying symptoms
fever, chest pain, coughing, purulent sputum, mucocutaneous bleeding, jaundice. Imaging examination
chest X-ray, CT scan and 3D reconstruction images or CT virtual bronchoscopy, bronchial angiography. Laboratory tests
blood test: WBC
Sputum: cells and bacterial examinations, sputum culture
Bronchial fiber endoscopy

Differential diagnosis
The most common causes for hemoptysis in adults are chest infections such as bronchitis or pneumonia. In children, hemoptysis is commonly caused by the presence of a foreign body in the airway. Other common causes include lung cancers and tuberculosis. Less common causes include aspergilloma, bronchiectasis, coccidioidomycosis, pulmonary embolism, pneumonic plague, and cystic fibrosis. Rarer causes include hereditary hemorrhagic telangiectasia (HHT or Rendu-Osler-Weber syndrome), Goodpastures syndrome, and granulomatosis with polyangiitis.
More common in women because of post-menopausal osteoporosis. History
The Colles fracture is named after Abraham Colles (1773–1843), an Irish surgeon, from Kilkenny who first described it in 1814 by simply looking at the classic deformity before the advent of X-rays. Ernest Amory Codman was the first to study it using X-rays. His article, published in the Boston Medical and Surgical Journal, now known as The New England Journal of Medicine, also developed the classification system.It is sometimes said that Claude Pouteau was the first to describe the Colles fracture (which is sometimes called the Pouteau-Colles fracture), but, according to P. Liverneaux, it is not the case. See also
