Local symptoms of pulmonary tuberculosis
The local symptoms of tuberculosis primarily require us to understand where tuberculosis occurs. Currently, tuberculosis in the lung tissues, trachea, bronchi, and pleura are all classified as pulmonary tuberculosis. The primary local symptoms are still respiratory symptoms, with the most common being cough and expectoration. Patients with tuberculosis generally have a slow onset, with most experiencing cough and expectoration that can persist for two weeks or more. Some patients may also exhibit symptoms like blood in the sputum or hemoptysis. Additionally, some patients may experience other symptoms; for example, those with pleural involvement might have irritative cough, chest pain, and difficulty breathing, while those with tracheobronchial involvement might exhibit a prolonged irritative cough. Some patients may also develop bronchial stenosis, which can lead to difficulty breathing.
Does tuberculosis cause a runny nose?
Do patients with tuberculosis have a runny nose? First, we need to understand what tuberculosis is. The pathogen of tuberculosis is Mycobacterium tuberculosis, commonly referred to as TB bacillus. Its primary site of infection is the lungs, but now we also classify and manage tracheobronchial and tuberculous pleurisy under pulmonary tuberculosis. However, these sites do not include the nasal part. Generally, patients with pulmonary tuberculosis show symptoms of the respiratory system and systemic symptoms. The most common respiratory symptoms include coughing and phlegm production for more than two weeks. Some patients may also experience hemoptysis, with varying amounts from mild to severe. A few patients may also experience chest pain. Additionally, patients with caseous pneumonia or significant pleural effusion may experience difficulty in breathing. Systemic symptoms of tuberculosis include fever, mainly characterized by afternoon tidal fever, with some patients exhibiting high fevers, and other general symptoms such as loss of appetite, weight loss, night sweats, and fatigue. However, the majority of patients with pulmonary tuberculosis do not exhibit nasal symptoms, meaning a runny nose is generally not a manifestation of tuberculosis. It could be possible that a tuberculosis patient might also have other infections or causative diseases, such as allergic rhinitis.
Can pneumonia vaccines prevent mycoplasma pneumonia?
Can pneumonia vaccines prevent Mycoplasma infections? First, we need to understand what pneumonia vaccines are. In our country, the most commonly used pneumonia vaccines are aimed at Streptococcus pneumoniae, which are divided into polysaccharide vaccines and conjugate vaccines. Polysaccharide vaccines are mainly suitable for individuals over two years old and include the 23-valent polysaccharide vaccine. This vaccine can prevent infections caused by twenty-three serotypes that often lead to S. pneumoniae infections, with over 90% of pneumonia caused by these twenty-three serotypes. However, the 23-valent polysaccharide vaccine does not prevent infections caused by other serotypes of S. pneumoniae. Additionally, the conjugate vaccine only prevents infections caused by either seven or thirteen serotypes. Since Mycoplasma is neither a bacterium nor a virus, it cannot be prevented by pneumonia vaccines, and currently, there is no vaccine available specifically for Mycoplasma infections.
Is respiratory failure contagious?
First, it's important to understand what respiratory failure is. Respiratory failure is a syndrome, not a disease, meaning it can result from many causes. For instance, airway obstruction, lung tissue pathology, diseases of the pulmonary vessels, and diseases of the thorax and pleura, as well as neuromuscular diseases, can all lead to impaired ventilation or gas exchange in the lungs. This impairment makes it impossible for the body to maintain adequate gas exchange even in a resting state, resulting in hypoxemia, with or without hypercapnia, which is referred to as respiratory failure. Therefore, there are many causes of respiratory failure, and some diseases are indeed contagious, such as SARS, H1N1, and H3N2. However, other causes, such as tumors or pulmonary embolism, are generally not contagious.
Does tuberculosis cause fever?
Does tuberculosis cause fever? The answer is definitely yes. Fever is one of the most common clinical manifestations of tuberculosis. Many tuberculosis patients experience low fevers, and a minority of patients, such as those with caseous tuberculosis or tuberculous pleurisy, may experience high fevers that can recur and persist. Moreover, tuberculosis patients may sometimes also have concurrent bacterial infections, which can cause the fever to last longer and be more difficult to control.
What are the symptoms of chronic bronchitis?
Chronic bronchitis is also colloquially known as "old chronic bronchitis." From this name, we can tell that patients usually develop the disease slowly with a long duration, lasting for years, even decades. The symptoms, such as coughing and expectoration, can acutely worsen repeatedly. Most patients cough and produce phlegm mostly when indoors, particularly noticeable upon waking in the morning and also possibly at night. The phlegm is typically white, sticky, or serous and foamy; occasionally, it may be blood-streaked. During acute exacerbations of chronic bronchitis or when accompanied by an infection, pus-like yellow phlegm or green bloody sputum may appear. Additionally, a small number of patients may experience wheezing, also known as asthmatic bronchitis.
Does chronic bronchitis cause chest tightness?
Chronic bronchitis is commonly known as "old chronic bronchitis." Its main symptoms are coughing and expectoration. These symptoms are chronic and recurrent, and the onset is gradual. Coughing and expectoration are usually more pronounced in the morning and may consist of white, sticky phlegm or frothy sputum. Occasionally, there may be blood in the phlegm, but significant hemoptysis or chest pain generally does not occur. A small portion of chronic bronchitis patients may experience wheezing, which some of them might describe as chest tightness, meaning that chest tightness can occur in some chronic bronchitis patients. Those experiencing wheezing are referred to as having asthmatic bronchitis. Additionally, some patients may also have coexisting conditions like bronchial asthma or, in later stages, chronic obstructive pulmonary emphysema, which can also lead to symptoms of chest tightness, shortness of breath, or respiratory difficulty.
Does chronic bronchitis hurt?
Chronic bronchitis, commonly known as "chronic bronchitis", generally does not involve pain. The main symptoms of chronic bronchitis are coughing and expectorating phlegm, which may or may not be accompanied by wheezing. The coughing and expectorating in chronic bronchitis are typically long-term and gradual, with recurrent episodes. The symptoms are usually more pronounced in the morning, characterized by white, sticky phlegm, and generally do not involve chest pain or pain in other areas. If a patient with chronic bronchitis experiences pain in various parts of the body, it is typically considered that they might have other concurrent illnesses.
Pneumothorax, which department should it go to?
Which department is better for pneumothorax treatment? There isn't a strict definition dictating which specific department one must visit for pneumothorax. Generally, you can visit the respiratory department or the cardiothoracic surgery department. If the patient's condition is very severe, then the first choice should be the emergency department, where emergency treatment can be provided before further referral.
How is chronic bronchitis diagnosed?
Chronic bronchitis: how is it diagnosed? First, we need to understand what chronic bronchitis is defined as. It refers to the chronic nonspecific inflammation of the trachea, bronchial mucosa, and surrounding tissues. We emphasize the chronic process, and currently, diagnosis is primarily based on clinical symptoms. This means the patient must exhibit symptoms such as coughing and expectoration, and these symptoms must persist for more than three months for at least two consecutive years. Additionally, it is crucial to exclude other diseases. Any organic disease that presents with symptoms of coughing, expectoration, and wheezing must be ruled out, such as tuberculosis, pneumoconiosis, lung abscess, lung cancer, heart disease, bronchiectasis, bronchial asthma, gastroesophageal reflux, and pulmonary interstitial fibrosis, among others.
