Coughing Blood
Hemoptysis or haemoptysis is the discharge of blood or blood-stained mucus through the mouth coming from the bronchi, larynx, trachea, or lungs. It does not necessarily involve coughing. 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 . 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 history ** history 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 there is blood-streaked sputum ** Probable source of bleeding: Is the blood coughed up, or vomited? * Bloody sputum ** color, characters: blood-streake ...

Pneumonia
Pneumonia is an Inflammation, inflammatory condition of the lung primarily affecting the small air sacs known as Pulmonary alveolus, alveoli. Symptoms typically include some combination of Cough#Classification, productive or dry cough, chest pain, fever, and Shortness of breath, difficulty breathing. The severity of the condition is variable. Pneumonia is usually caused by infection with viruses or bacteria, and less commonly by other microorganisms. Identifying the responsible pathogen can be difficult. Diagnosis is often based on symptoms and physical examination. Chest X-rays, blood tests, and Microbiological culture, culture of the sputum may help confirm the diagnosis. The disease may be classified by where it was acquired, such as community- or hospital-acquired or healthcare-associated pneumonia. Risk factors for pneumonia include cystic fibrosis, chronic obstructive pulmonary disease (COPD), sickle cell disease, asthma, diabetes, heart failure, a history of smoking, ...

Hereditary Hemorrhagic Telangiectasia
Hereditary hemorrhagic telangiectasia (HHT), also known as Osler–Weber–Rendu disease and Osler–Weber–Rendu syndrome, is a rare autosomal dominant genetic disorder that leads to abnormal blood vessel formation in the Human skin, skin, mucous membranes, and often in organs such as the lungs, liver, and brain. It may lead to epistaxis, nosebleeds, Gastrointestinal bleeding, acute and chronic digestive tract bleeding, and various problems due to the involvement of other organs. Treatment focuses on reducing bleeding from telangiectasias, and sometimes surgery or other targeted interventions to remove arteriovenous malformations in organs. Chronic bleeding often requires iron supplements, iron infusions and sometimes blood transfusions. HHT is transmitted in an Dominance (genetics), autosomal dominant fashion, and occurs in one in 5,000–8,000 people in North America. The disease carries the names of Sir William Osler, Henri Jules Louis Marie Rendu, and Frederick Parkes Weber ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cystic Fibrosis
Cystic fibrosis (CF) is a genetic disorder inherited in an autosomal recessive manner that impairs the normal clearance of Sputum, mucus from the lungs, which facilitates the colonization and infection of the lungs by bacteria, notably ''Staphylococcus aureus''. CF is a rare genetic disorder that affects mostly the lungs, but also the pancreas, liver, kidneys, and intestine. The hallmark feature of CF is the accumulation of thick mucus in different organs. Long-term issues include Shortness of breath, difficulty breathing and coughing up mucus as a result of frequent pneumonia, lung infections. Other signs and symptoms may include Sinusitis, sinus infections, failure to thrive, poor growth, Steatorrhea, fatty stool, Nail clubbing, clubbing of the fingers and toes, and infertility in most males. Different people may have different degrees of symptoms. Cystic fibrosis is inherited in an autosomal recessive manner. It is caused by the presence of mutations in both copies (alleles) ...

Pneumonic Plague
Pneumonic plague is a severe lung infection caused by the bacterium '' Yersinia pestis''. Symptoms include fever, headache, shortness of breath, chest pain, and coughing. They typically start about three to seven days after exposure. It is one of three forms of plague, the other two being septicemic plague and bubonic plague. The pneumonic form may occur following an initial bubonic or septicemic plague infection. It may also result from breathing in airborne droplets from another person or animal infected with pneumonic plague. The difference between the forms of plague is the location of infection; in pneumonic plague the infection is in the lungs, in bubonic plague the lymph nodes, and in septicemic plague within the blood. Diagnosis is by testing the blood, sputum, or fluid from a lymph node. While vaccines are being developed, in most countries they are not yet commercially available. Prevention is by avoiding contact with infected rodents, people, or cats. It is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pulmonary Embolism
Pulmonary embolism (PE) is a blockage of an pulmonary artery, artery in the lungs by a substance that has moved from elsewhere in the body through the bloodstream (embolism). Symptoms of a PE may include dyspnea, shortness of breath, chest pain particularly upon breathing in, and coughing up blood. Symptoms of a deep vein thrombosis, blood clot in the leg may also be present, such as a erythema, red, warm, swollen, and painful leg. Signs of a PE include low blood oxygen saturation, oxygen levels, tachypnea, rapid breathing, tachycardia, rapid heart rate, and sometimes a mild fever. Severe cases can lead to Syncope (medicine), passing out, shock (circulatory), abnormally low blood pressure, obstructive shock, and cardiac arrest, sudden death. PE usually results from a blood clot in the leg that travels to the lung. The risk of blood clots is increased by advanced age, cancer, prolonged bed rest and immobilization, smoking, stroke, long-haul travel over 4 hours, certain genetics, ...

Coccidioidomycosis
Coccidioidomycosis (, ) is a mammalian mycosis, fungal disease caused by ''Coccidioides immitis'' or ''Coccidioides posadasii''. It is commonly known as cocci, Valley fever, California fever, desert rheumatism, or San Joaquin Valley fever. Coccidioidomycosis is endemic (epidemiology), endemic in certain parts of the United States in Arizona, California, Nevada, New Mexico, Texas, Utah, and northern Mexico. Description ''C. immitis'' is a Polymorphism (biology), dimorphic saprophytic fungus that grows as a mycelium in the soil and produces a spherule form in the Host (biology), host organism. It resides in the soil in certain parts of the southwestern United States, most notably in California and Arizona. It is also commonly found in northern Mexico, and parts of Central America, Central and South America. ''C. immitis'' is dormant during long dry spells, then develops as a mold with long filaments that break off into airborne spores when it rains. The spores, known as arthroc ...

Bronchiectasis
Bronchiectasis is a disease in which there is permanent enlargement of parts of the bronchi, airways of the lung. Symptoms typically include a chronic cough with sputum, mucus production. Other symptoms include shortness of breath, hemoptysis, coughing up blood, and chest pain. Wheezing and nail clubbing may also occur. Those with the disease often get lung infections. Bronchiectasis may result from a number of infection, infectious and acquired causes, including measles, pneumonia, tuberculosis, immune system problems, as well as the genetic disorder cystic fibrosis. Cystic fibrosis eventually results in severe bronchiectasis in nearly all cases. The cause in 10–50% of those without cystic fibrosis is unknown. The mechanism of disease is breakdown of the airways due to an excessive inflammatory response. Involved airways (bronchi) become enlarged and thus less able to clear secretions. These secretions increase the amount of bacteria in the lungs, resulting in airway blockage ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aspergilloma
An aspergilloma is a clump of mold which exists in a body cavity such as a paranasal sinus or an organ such as the lung. By definition, it is caused by fungi of the genus ''Aspergillus''. Signs and symptoms People with aspergillomata typically remain asymptomatic until the condition is fairly advanced; in some cases even for decades. Diagnosis is often made as a result of an incidental finding on a chest X-ray or CT scan that may be performed as part of the workup for another unrelated condition. However, a small percentage of aspergillomata invade into a blood vessel which can result in bleeding. Thus, the most common symptom of associated with aspergillomata is coughing up blood (hemoptysis). This may result in life-threatening hemorrhage, though the amount of blood lost is usually inconsequential. Aspergillomata can also form in other organs. They can form abscesses in solid organs such as the brain or kidney, usually in people who are immunocompromised. They can also develop ...

Respiratory Tract
The respiratory tract is the subdivision of the respiratory system involved with the process of conducting air to the alveoli for the purposes of gas exchange in mammals. The respiratory tract is lined with respiratory epithelium as respiratory mucosa. Air is breathed in through the nose to the nasal cavity, where a layer of nasal mucosa acts as a filter and traps pollutants and other harmful substances found in the air. Next, air moves into the pharynx, a passage that contains the intersection between the oesophagus and the larynx. The opening of the larynx has a special flap of cartilage, the epiglottis, that opens to allow air to pass through but closes to prevent food from moving into the airway. From the larynx, air moves into the trachea and down to the intersection known as the carina that branches to form the right and left primary (main) bronchi. Each of these bronchi branches into a secondary (lobar) bronchus that branches into tertiary (segmental) bronchi, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Foreign Body
A foreign body (FB) is any object originating outside the body of an organism. In machinery, it can mean any unwanted intruding object. Most references to foreign bodies involve propulsion through natural orifices into hollow organs. Foreign bodies can be inert or irritating. If they irritate they will cause inflammation and scarring. They can bring infection into the body or acquire infectious agents and protect them from the body's immune defenses. They can obstruct passageways either by their size or by the scarring they cause. Some can be toxic or generate toxic chemicals from reactions with chemicals produced by the body, as is the case with many examples of ingested metal objects. With sufficient force (as in firing of bullets), a foreign body can become lodged into nearly any tissue. Gastrointestinal tract One of the most common locations for a foreign body is the alimentary tract. It is possible for foreign bodies to enter the tract from the mouth or rectum. Both c ...
