Causes respiratory tract infection

Currently the trend of social development, the global climate change, environmental pollution, emissions, dust ... has led to the percentage of people infected with respiratory diseases increasing, especially upper respiratory tract infection.

 
Respiratory tract infections in patients with mostly moderate, but may aggravate up in subjects susceptible, causing more severe variant.

What causes tuberculosis?

 Grandparents old adage of "Lao Feng shrink from them incurable" to speak of the dangers of tuberculosis.

People also know that tuberculosis is a disease that is very contagious and common disease. When medical examination and chest x-ray or illuminated glass, patients with TB often hear doctors said was burnt lungs so it is often referred to as melasma pulmonary tuberculosis.

cause pulmonary fibrosis

Pulmonary fibrosis is a chronic condition in which tissue deep within the lungs are damaged, thickened, hard due to loss of elasticity (elasticity), and scarring. The scar is called pulmonary fibrosis. Because pulmonary fibrosis and scarring stiffer, will limit the ability of the patient to breathe.

 

There are many causes of pulmonary fibrosis

- Lung disease secondary to lung injury: tuberculosis, pneumonia, pulmonary embolism, ..

. Clinical signs of lung cancer

Lung cancer (lung cancer is often called) is the most common type of cancer in men. Lung cancer is a malignant proliferation of bronchial epithelial cells. The cause of lung cancer, but so far it is not clear that smoking tobacco is the leading risk factor.
 
  Clinical symptoms of lung cancer are varied; change from no symptoms only discovered accidentally when an X-ray examination

Pleural effusion

Each lungs in the chest is surrounded by two very thin membrane called the pleura. Two membranes form a virtual compartment, normally only a few ml to make the pleural surface is smooth when rubbed together.


  When you have a medical condition that affects the pleura, the body's fluid can accumulate in the pleural cavity. When we say that there is pleural effusion. Pleural effusion is a common manifestation of many different diseases. In Vietnam, the common diseases that cause pleural effusion as tuberculosis, cancer, heart failure, liver, kidney, and lung inflammation.

Pneumonia

Pneumonia is a common disease, showing inflammation of lung tissue caused by pathogens mostly bacteria. Typical symptoms are high fever, chills, cough and purulent sputum test pleural chest pain (pain when inhaling deeply, coughing). Tests to help diagnose the disease is X-ray. When not diagnosed and treated promptly, usually progressive severe pneumonia can cause acute respiratory failure, sepsis and death. Go see a doctor soon to be medical examination, chest x-rays, blood tests and antibiotic therapy appropriate timely treatment is the key to success.

The common symptoms as pneumonia?

Clinical signs:

Pneumonia Patients often appear fever, cough purulent sputum production, chest pain type pleura (ie, chest pain when coughing, deep breathing, postural changes).

Chronic Obstructive Pulmonary Disease

Chronic Obstructive Pulmonary Disease (COPD English acronym) is very common in Vietnam and worldwide. COPD is a chronic inflammation of the airways caused by exposure to harmful elements from the environment led by tobacco, dust, smoke and pollution.

Chronic inflammation has been swollen airways, then fibrosis, excessive salivation and bronchial smooth muscle contraction as airway obstruction, the walls of the alveoli are destroyed as the alveoli stretch unusual cause gas accumulation in the lungs.

Asthma

ABSTRACT

Asthma is a very common disease in Vietnam and worldwide. Asthma is a chronic inflammation of the airways as a result of the interaction between atopic allergy and asthma triggers from the environment. Chronic inflammation has been airway swelling, excessive salivation and bronchial smooth muscle contraction as airway obstruction. 

 

Typical symptoms of asthma include coughing, wheezing, shortness of breath, tightness in the chest several times repeated, occurs when the body exposed to the factors that cause asthma symptoms such as changing weather, pollen , dust, odor, respiratory viral exposure. Tests help confirm the diagnosis of asthma is up there as test Respiratory ± dilated bronchial stimulation test. Progression of chronic asthma can not be cured completely but can be treated to control the disease thoroughly. Go see a doctor soon to be doctor, Respiratory Measurement sign, anti-inflammatory therapy with inhaled long-term follow-up treatment is the key to successful asthma control.

The common symptoms of asthma when ?

Typical clinical symptoms :

Patients with asthma often have respiratory symptoms have the following characteristics:

+          The symptoms: cough or coughing white mucus phlegm, dyspnea primarily on the exhale, wheezing and tightness in the chest.

+         Features hint: the above symptoms come back up again and always changing. Symptoms vary with time: more night than during the day; more time allocated two rainy seasons - the sun, the cold season. Symptoms vary with exposure to allergens: more after physical activity, exposure to dust, odor pungent, after eating food allergies such as shellfish, marine fish, beef, chicken, when see things melancholy sadness or worry too high. Among the symptomatic phase completely normal patients as many misdiagnosed as neurological disorders or diseases plant "Imagine" by "psychological"

+         The comorbid conditions: contact dermatitis: eczema, rashes; allergic rhinitis: nasal itching, nasal congestion, runny nose; conjunctivitis allergy: itching eyes, red eyes.

Clinical symptoms of asthma varied so GINA (organization and management of asthma worldwide) gave the symptoms suggestive of asthma and advised people to have these symptoms, they must have a doctor to examination and respiration signed definitive diagnosis of asthma:

+         There bouts of recurrent wheezing.

+         There cough at night to wake the patient.

+         There wheezing and cough after physical activity.

+         There wheezing, tightness in the chest or coughing after exposure to airborne allergens such as pollen, strong odors, dust pollution.

+         Flu symptoms "into the lungs," more than 10 days out.

+         The symptoms improve with asthma medication such as bronchodilators, anti-inflammatory steroids.

Clinical symptoms are not typical - especially the clinical possible :

GINA has launched two clinical asthma may not particularly like the typical asthma symptoms in the form of cough and asthma that is triggered asthma after exercise.

+         Asthma, coughs: asthma patients only major coughs sometimes the only symptom is a cough. Asthma is the most common form of cough in children and occurs at night or during the examination that took place during the day can be completely normal. Patients often have visit so many places and was diagnosed with many different diseases, but no response to treatment. To diagnose asthma, coughs need to track changes in respiratory function during the day, assess bronchial response properties and affinity cell counts attempted in negotiations.

+         Asthma after exertion: for some patients with asthma, symptoms appear only after physical exertion. Symptoms typically appear from 5-10 minutes after the end of exertion (very rarely symptoms appear during exertion), patients with typical symptoms of asthma, or sometimes just a million very irritating cough, symptoms will recover naturally after 30-45 minutes. Asthma after exertion can appear in any weather conditions, but the most common is when the motor in cold and dry weather. To diagnose asthma after exertion should be done after signing measuring respiratory effort by the 8-minute test run

Subclinical symptoms :

Respiration is up standard test for diagnosing asthma.

>> Patients need to prepare before measuring respiratory Register

+         Case, respiratory sign indicates airway obstruction with complete recovery after bronchodilator test methods.

+         Where the patient to doctor outside asthma, respiratory measurement can sign completely normal. So if breathing is normal sign does not exclude the diagnosis of asthma.

+         In case of normal respiratory signed, to completely eliminate the diagnosis of asthma need to make up for respiratory measurements do not test specific bronchial stimulation with methacoline or histamine. Negative test results allow the exclusion sure asthma.

+         Where do sign respiratory stimulation test nonspecific bronchial histamine by methacholin or positive, can not exclude the diagnosis of asthma, but also does not allow definitive diagnosis of asthma, this time can be used to treat asthma as a diagnostic measure.

X-ray of asthma completely normal, X-ray tests to help diagnose asthma but does not eliminate the diagnosis of other symptoms such as asthma, pneumonia, tuberculosis, lung cancer.

CBC tests may show increased eosinophils evidence for allergic condition of the body.

Examination of skin prick test with the specific allergen, measured the levels of specific IgE antibodies in serum contribute diagnosed atopic sensitization to allergens.

 

6 causes of respiratory disease

You often suffer from respiratory diseases. Check that, around you there are "enemies" of the following is not:

1. "Addiction" alcohol, tobacco

Wine, beer, tobacco is one of the factors leading to damage liver function, kidney, respiratory system. In tobacco smoke contains more than 4,000 chemicals, including nicotine is not only harmful to the lungs, but also adversely affect the human brain.

What causes upper respiratory infections

Inflammation of the upper respiratory tract due to many different causes, may be due to an allergy to the weather, with different types of allergens (antigens) in the air, the effects of dust or chemicals, cigarette smoke ( smoking or inhaling secondhand smoke, pipe tobacco by others released) or by pathogenic microorganisms (fungi, bacteria, viruses). In this article, we mentioned pathogens are bacteria.
 
By the research and scientific experiments, it was found mostly cause upper respiratory tract infections are viral.
