Lung cancer kills more men and women than any other form of cancer. Eight out of 10 lung cancers are due
to tobacco smoke. Lung cancers are classified as either small cell or non-small
cell cancers.
Sinus infection (sinusitis) signs and symptoms include headache, fever, and facial tenderness, pressure, or pain. Treatments of sinus infections are generally with antibiotics and at times, home remedies.
GERD (gastroesophageal reflux disease) is a condition in which the acidified liquid
contents of the stomach backs up into the esophagus. The symptoms of uncomplicated GERD are heartburn,
regurgitation, and nausea. Effective treatment is available for most patients with GERD.
Pneumonia is inflammation of one or both lungs with consolidation. Pneumonia is frequently but not always due to infection. The infection may be bacterial, viral, fungal or parasitic. Symptoms may include fever, chills, cough with sputum production, chest pain, and shortness of breath.
A pulmonary embolism occurs when a piece of a blood clot from deep vein thrombosis (DVT) breaks off and travels to an artery in the lung where it blocks the artery and damages the lung. The most common symptoms of a pulmonary embolism are shortness of breath, chest pain, and a rapid heart rate.
Allergic rhinitis symptoms include an itchy, runny nose, sneezing, itchy ears, eyes, and throat. Seasonal allergic rhinitis (also called hay fever) is usually caused by pollen in the air. Perennial allergic rhinitis is a type of chronic rhinitis and is a year–round problem, often caused by indoor allergens, such as dust, animal dander, and pollens that may exist at the time. Treatment of chronic rhinitis and post nasal drip are dependant upon the type of rhinitis condition.
Whooping cough (pertussis) is highly contagious respiratory infection that is caused by the bacteria Bordetella pertussis. There are an estimated 300,000 plus deaths annually from whooping cough (pertussis). Whopping cough commonly affects infants and young children, but can be prevented with immunization with the vaccine. First stage whooping cough symptoms are a runny nose, sneezing, low-grade fever, a mild cough with the cough gradually becoming more severe. After one to two weeks, the second stage of whooping cough begins.
Angina is chest pain that is due to an inadequate supply of oxygen to the heart muscle.
Angina can be caused by coronary artery disease or spasm of the coronary
arteries. EKG, exercise treadmill, stress echocardiography, stress thallium, and cardiac
catheterization are important tests used in the diagnosis of angina.
An upper respiratory infection is a contagious infection of the structures of the upper respiratory tract, which includes the sinuses, nasal passages, pharynx, and larynx. Common causes of an upper respiratory infection include bacteria and viruses such as rhinoviruses, group A streptococci, influenza, respiratory syncytial, whooping cough, diphtheria, and Epstein-Barre. Examples of symptoms of upper respiratory infection include sneezing, sore throat, cough, fever, and nasal congestion. Treatment of upper respiratory infection are generally with OTC medication and home remedies.
Bronchitis is a disease of the respiratory system in which the bronchial passages become inflamed. There are two types of bronchitis, acute and chronic. Symptoms of acute bronchitis include frequent cough with mucus, lack of energy, wheezing, and possible fever. Treatment may require medication such as bronchial inhalers and predinsone. Supportive treatment is focused on relieving the symptoms with fever reducers, cough suppressants, and rest. Treatment may be more aggressive in patients with pre-existing conditions such as empyema, COPD, or cigarette smoking.
Esophageal cancer is a disease in which malignant cells form in the esophagus. Risk factors of cancer of the esophagus include smoking, heavy alcohol use, Barrett's esophagus, being male and being over age 60. Severe weight loss, vomiting, hoarseness, coughing up blood, painful swallowing, and pain in the throat or back are symptoms. Treatment depends upon the size, location and staging of the cancer and the health of the patient.
Sepsis (blood poisoning) is a potentially deadly infection with signs and symptoms that include elevated heart rate, low or high temperature, rapid breathing and/or a white blood cell count that is too high or too low and has more than 10% band cells. Most cases of sepsis are caused by bacterial infections, and some cases are caused by fungal infections. Treatment requires hospitalization, IV antibiotics, and therapy to treat any organ dysfunction.
Polycythemia (elevated red blood cell count) causes are either primary (aquired or genetic mutations) or secondary (diseases, conditions, high altitude). Treatment of polycythemia depends on the cause.
Chest pain is a common complaint by a patient in the ER. Causes of chest pain include broken or bruised ribs, pleurisy, pneumothorax, shingles, pneumonia, pulmonary embolism, angina, heart attack, costochondritis, pericarditis, aorta or aortic dissection, and reflux esophagitis. Diagnosis and treatment of chest pain depends upon the cause and clinical presentation of the patient's chest pain.
Non-Hodgkin's lymphoma is cancer of the lymphatic system, a vital part of the body's immune system. Symptoms include swollen lymph nodes, fever, night sweats, coughing, weakness, chest pain, unexplained weight loss, and abdominal pain. Treatment depends on which type of non-Hodgkin's lymphoma you have, the stage of the cancer, your age, how fast the cancer is growing, and whether you have other health problems.
Emphysema is a progressive disease of the lungs. The primary cause of emphysema is smoking. Alpha 1-antitrypsin deficiency is a rare disorder that has a genetic predisposition to emphysema. Aging, IV drug use, immune deficiencies, and connect tissue illnesses are also risk factors for emphysema. Emphysema is a subtype of COPD (chronic obstructive pulmonary disease, COLD). Symptoms include shortness of breath and wheezing. Management of symptoms may be achieved with medications, quitting smoking, pulmonary rehabilitation, or surgery.
COPD (chronic obstructive pulmonary disease) is a disorder that persistently obstructs bronchial airflow. COPD mainly involves three related conditions, chronic bronchitis, chronic asthma, and emphysema. Symptoms of COPD include chronic cough, shortness of breath, frequent respiratory infections, wheezing, morning headaches, and pulmonary hypertension. Treatment of COPD is focused on the related condition(s).
Pulmonary fibrosis is scarring throughout the lungs. Pulmonary fibrosis can be caused by many conditions including chronic inflammatory processes, infections, environmental agents, exposure to ionizing radiation, chronic conditions, and certain medications. Symptoms include shortness of breath, coughing, and diminished exercise tolerance. Treatment options are dependent on the type of pulmonary fibrosis; lung transplant and/or medications are optons.
Cystic fibrosis is a disease of the mucus and sweat glands. Cystic fibrosis is an inherited disease. The outcome of the disease leaves the body malnourished, bulky and fouls smelling stools, vitamin insufficiency, gas, painful or swollen abdomen, infertility, susceptible to heat emergencies, and respiratory failure. There is no cure for cystic fibrosis, treatment of symptoms is used to manage the disease.
Asthma is a common disorder in which
chronic inflammation of the bronchial tubes (bronchi) makes them swell, narrowing the airways. Signs and symptoms include shortness of breath, chest tightness,
cough and wheezing.
Mold exposure may cause symptoms in people who are sensitive to molds. Symptoms of mold allergy include sneezing, runny nose, wheezing, coughing, redness of the eyes, and rash. Prevent mold growth by keeping indoor humidity low, between 30%-50%, using bathroom fans when showering, repairing plumbing leaks quickly, and using an air conditioner during humid seasons.
Croup is a contagious viral infection that affects children's respiratory system. Symptoms include a barking cough, stridor, fever and difficulty breathing.
The common cold (viral upper respiratory tract infection) is a contagious illness that may be caused by various viruses. Symptoms include a stuffy nose, headache, cough, sore throat, and maybe a fever. Antibiotics have no effect upon the common cold, and there is no evidence that zinc and vitamin C are effective treatments.
A subconjunctival hemorrhage is bleeding under the eye's conjunctiva. There is usually no obvious cause for a subconjunctival hemorrhage, but it may be caused by sneezing, vomiting, infections on the outside of the eye, coughing, and clotting disorders. Symptoms and signs include blood in the white of the eye and a sense of fullness under the lid. No treatment is needed.
Barrett's esophagus occurs as a complication of chronic gastroesophageal reflux disease (GERD), primarily in white males. GERD refers to the reflux of acidic fluid from the stomach into the esophagus (the swallowing tube), and is classically associated with heartburn.
Laryngitis is an inflammation of the voice box (vocal cords). The most common cause of acute laryngitis is infection, which inflames the vocal cords. Symptoms may vary from degree of laryngitis and age of the patient. Common symptoms include croup, hoarse cough, fever, cold, runny nose, dry cough, and loss of voice. Chronic laryngitis generally lasts more than three weeks. Causes other than infection include smoking, excess coughing, GERD, and more. Treatment depends on the cause of laryngitis.
Pleurisy, an inflammation of the lining around the lungs, is associated with sharp chest pain upon breathing in. Cough, chest tenderness, and shortness of breath are other symptoms associated with pleurisy. Pleurisy pain can be managed with pain medication and by external splinting of the chest wall.
Chronic fatigue syndrome is a debilitating and complex disorder characterized by profound fatigue that lasts 6 months or longer, is not improved by bed rest, and may be worsened by physical or mental activity.
Chronic bronchitis is a cough that occurs daily with production of sputum that lasts for at least three months, two years in a row. Causes of chronic bronchitis include cigarette smoking, inhaled irritants, and underlying disease processes (such as asthma, or congestive heart failure). Symptoms include cough, shortness of breath, and wheezing. Treatments include bronchodilators and steroids. Complications of chronic bronchitis include COPD and emphysema.
Swine flu (swine influenza) is a respiratory disease caused by viruses
(influenza viruses) that infect the respiratory tract of pigs and result in
nasal secretions, a barking cough, decreased appetite, and listless behavior.
Swine flu viruses may mutate (change) so that they are easily transmissible among humans.
The 2009 swine flu outbreak is due to infection with the so-called H1N1 virus and was first observed in Mexico.
Symptoms of swine flu in humans are similar to most influenza infections: fever (100 F or greater), cough, nasal secretions, fatigue, and headache.
Two antiviral agents, zanamivir (Relenza) and oseltamivir (Tamiflu), have been reported to help prevent or reduce the effects of swine flu if taken within 48 hours of the onset of symptoms.
