What department should I go to for asthma?
What department should you visit for asthma? First, we need to clarify the definition of asthma. The term "asthma" most commonly refers to bronchial asthma, but also to cardiac asthma. Starting with bronchial asthma, it is a respiratory system disease, and the most appropriate department to visit is the Department of Respiratory Medicine. Of course, in the case of an acute attack of bronchial asthma, if the condition of the patient is very severe, then they may choose to visit the emergency department. Additionally, in some areas where there is no Department of Respiratory Medicine available, such as in rural areas or community health centers, patients can only visit a general internal medicine department. As for cardiac asthma, it is a concept that is gradually being phased out. Cardiac asthma, as the name suggests, is associated with cardiovascular system diseases. Under these circumstances, the most fitting department to visit is the Department of Cardiology. Of course, if the patient's condition is critical, then the most suitable choice is still the emergency department, where emergency physicians will decide how to handle the patient's condition based on their specific medical needs.
How is tuberculosis transmitted?
How is pulmonary tuberculosis transmitted? First, we need to know the pathogen of pulmonary tuberculosis, which is the tuberculosis bacillus. Tuberculosis bacillus is a type of bacterium that can live in our surrounding environment. Pulmonary tuberculosis also needs a source of infection, that is, a patient carrying the tuberculosis bacillus. The most common source of tuberculosis infection is usually patients with secondary pulmonary tuberculosis. Then, its mode of transmission mainly includes coughing, sneezing, laughing, and talking loudly, which can release the tuberculosis bacilli from the patient into the air, spreading them through droplets. Droplet transmission is the most important route for the spread of pulmonary tuberculosis. Additionally, pulmonary tuberculosis can also be transmitted through other routes such as the gastrointestinal tract or the skin, although these methods of transmission are less common.
COPD and chronic bronchitis differences
COPD stands for Chronic Obstructive Pulmonary Disease, also commonly referred to as chronic obstructive lung disease. It is a chronic inflammation of the respiratory tract caused by inhalation of tobacco smoke, other types of smoke, harmful gases, or particulate irritants. This inflammation persists, eventually leading to structural changes in the airways, and symptoms such as coughing up phlegm and difficulty breathing. Chronic bronchitis is diagnosed primarily based on symptoms. Also known as chronic obstructive bronchitis, it is defined by symptoms of coughing, phlegm, or wheezing lasting more than three months per year and persisting for over two years, while excluding other diseases. There is a close connection between chronic bronchitis and COPD. If a patient with chronic bronchitis experiences worsening of their condition characterized by restricted airflow, as identified through pulmonary function tests indicating airflow limitation, they can then be diagnosed with Chronic Obstructive Pulmonary Disease. However, if a patient only exhibits symptoms of chronic bronchitis and maintains normal lung function, they cannot be diagnosed with Chronic Obstructive Pulmonary Disease under such circumstances.
Does bronchitis cause asthma?
Bronchitis can be classified into acute bronchitis and chronic bronchitis based on the onset and progression of the condition. Acute bronchitis usually begins suddenly, with generally mild systemic symptoms. It can include fever and is mostly characterized by a dry cough or a small amount of mucous sputum. Over time, the amount of sputum may increase and the coughing may intensify, occasionally accompanied by blood-streaked sputum. There is generally no significant hemoptysis or chest pain. The duration of cough and expectoration can be quite long, potentially lasting two to three weeks. A small portion of patients may experience prolonged symptoms, eventually progressing to chronic bronchitis. The most common symptoms of chronic bronchitis are also cough and expectoration, but these symptoms last much longer, typically persisting for more than two years and occurring for three months each year. A small number of bronchitis patients may experience bronchial spasms or bronchial asthma, leading to varying degrees of chest tightness, shortness of breath, or wheezing.
Which department should I go to for bronchial asthma?
In our common areas, we would visit the Department of Respiratory Medicine for conditions such as bronchial asthma, which is a respiratory system disease. The Department of Respiratory Medicine is the most specialized department for treating bronchial asthma. However, in some areas, such as those below the county level like town health centers or community clinics, a respiratory medicine department might not be available. In such cases, we can only visit the general internal medicine department, also known as the major internal medicine department. Generally, bronchial asthma is treated in the outpatient clinics of these departments. However, if an acute attack of bronchial asthma occurs, causing breathing difficulties and a sudden exacerbation of the condition, it then becomes necessary to visit the emergency medicine department. Emergency doctors will handle the situation and then decide whether the patient should continue treatment under observation in the emergency department or need hospitalization, etc.
What department should I go to for pneumonia?
Pneumonia, as the name suggests, is inflammation of the lungs and belongs to the category of respiratory diseases. Therefore, the primary department to consult is Respiratory Medicine. In places where there is no Respiratory Medicine department, such as community health service centers or township health clinics, patients would have to consult the general internal medicine department instead. Of course, if the symptoms of pneumonia are severe and the condition is critical, and it happens outside of regular outpatient hours, then the patient must be seen by the emergency medicine department. The emergency medicine department will manage and triage pneumonia patients, and then decide their next steps, such as whether to transfer them to the ICU, a regular Respiratory Medicine department, or keep them for observation in the emergency department.
The difference between silicosis and pneumoconiosis.
The difference between silicosis and pneumoconiosis. First, let's understand pneumoconiosis. Pneumoconiosis is a systemic disease characterized primarily by diffuse fibrosis of lung tissues, caused by the inhalation of occupational dusts during production activities. There are many types of dust that can cause pneumoconiosis, such as silica dust, coal dust, asbestos, talc, and some dusts produced during the manufacturing and transportation of cement. Silicosis is the most common type of pneumoconiosis. It is caused by the long-term inhalation of substantial amounts of free silica dust, and it primarily presents as extensive nodular fibrosis in the lungs. Silicosis belongs to the category of pneumoconiosis, and it is the most common, fastest progressing, and most dangerous type of pneumoconiosis. In simple terms, silicosis is a type of pneumoconiosis, but not all pneumoconiosis is silicosis.
Causes of Chronic Bronchitis
The causes of chronic bronchitis are not yet very clear. It is currently speculated that it may be the result of multiple factors interacting over a long period. The factors most closely associated with the occurrence of chronic bronchitis primarily include smoking, cigarette smoke, dust, and irritants such as sulfur dioxide, nitrogen dioxide, chlorine, ozone, etc. Additionally, some infectious factors may also be somewhat related to the occurrence of chronic bronchitis, with the most common possibly being infections by mycoplasma, bacteria, or viruses. Furthermore, chronic bronchitis may be related to age, climate, and other factors. Overall, the triggers of chronic bronchitis are not very clear at present, and it is advised to eliminate these risk factors as much as possible if present.
What is tuberculosis?
Tuberculosis is a disease where the bacterium Mycobacterium tuberculosis infects the lungs. It is a persistent bacterium that grows slowly. Tuberculosis is an infectious disease and quite common historically, often referred to as consumption in the past, as mentioned in the novels of Lu Xun. In modern times, tuberculosis is relatively manageable if the infection has not developed resistance to drugs. Proper anti-tuberculosis treatment can result in a cure rate exceeding 90% on the first attempt. However, if the treatment is not adhered to correctly—if the patient stops taking the medication prematurely or does not follow the prescribed regimen—the bacteria may develop resistance, reducing the effectiveness of the treatment. This is particularly problematic in elderly patients, who might also experience adverse reactions to tuberculosis medications, making treatment difficult. Thus, while tuberculosis is generally treatable, infections with drug-resistant strains can be fatal if not managed properly.
Do people with asthma cough?
The asthma commonly referred to is bronchial asthma, which is primarily characterized by recurrent episodes of breathing difficulty. This difficulty in breathing is mainly manifested as chest tightness and shortness of breath. Additionally, asthma is often triggered by upper respiratory tract infections. Therefore, most asthma patients experience coughing and expectoration during acute attacks. There is also a special type of asthma known as cough variant asthma, which, as the name suggests, is primarily characterized by coughing. This type of cough is generally dry with little to no sputum, or it involves a small amount of mucous sputum. The coughing can occur during the day but is generally more pronounced at night.
