The difference between bronchial asthma and pulmonary emphysema.
Bronchial asthma and emphysema are two different diseases. Bronchial asthma typically manifests as episodic coughing, chest tightness, and wheezing. Patients often develop this condition in childhood and adolescence, and it is relatively rare in the elderly. Emphysema, on the other hand, is often related to long-term smoking and is usually seen in middle-aged and older patients. Early stages of emphysema may only be evident on a chest CT and may not show significant symptoms of chest tightness. However, as the disease progresses, patients often experience noticeable chest tightness and difficulty breathing, and the condition tends to progressively worsen. Patients typically eventually develop complications such as chronic respiratory failure and chronic pulmonary heart disease. Therefore, the characteristics of bronchial asthma and emphysema are different. However, it is important to note that in patients with bronchial asthma, if the condition is not controlled and continues to progress, it might also lead to the development of emphysema, chronic respiratory failure, pulmonary heart disease, and other related conditions.
What are the symptoms of pleurisy?
Pleurisy often presents with symptoms of chest pain, which tends to worsen with deep breathing. Patients with pleurisy may also experience a feeling of tightness in the chest, possibly caused by a significant accumulation of fluid in the chest cavity due to the pleurisy. Sometimes, this tightness could also be due to severe chest pain that makes the patient reluctant to inhale deeply. Patients with pleurisy are likely to exhibit symptoms of fever. It is important to note that pleurisy caused by different factors may have distinct clinical features. For example, purulent pleurisy often presents with high fever, while tuberculous pleurisy may show symptoms of tuberculosis intoxication like low-grade fever in the afternoon and night sweats. However, some cases of tuberculous pleurisy might present with high fever, and others may not have noticeable fever at all. Additionally, viral pleurisy usually features prominently painful symptoms in the chest.
Can you eat oranges with an upper respiratory tract infection?
Upper respiratory infections can include orange in the diet; these infections are usually viral, and typically there are no specific therapeutic drugs available, only symptomatic treatment is provided. Additionally, patients should also consider eating some fruits and drinking more plain water while maintaining a light diet; fruits like oranges and apples are suitable. Furthermore, patients with severe symptoms of upper respiratory infection may also need to use some cold medicines to alleviate their symptoms. Generally, upper respiratory infections are self-limiting, and patients can gradually recover with symptomatic treatment and dietary adjustments mentioned above. However, it is important to note that some upper respiratory infections may be bacterial, such as acute suppurative tonsillitis, which is a bacterial infection and requires anti-infection treatment.
Does bronchial asthma have wheezing sounds?
During an acute attack of bronchial asthma, patients often have wheezing sounds in their lungs, but it's important to note that some patients may not exhibit wheezing, such as those with chest tightness or cough variant asthma, who only show symptoms of chest tightness and typically do not have wheezing on auscultation. However, administering inhaled corticosteroids and bronchodilators can relieve their condition. Additionally, during a severe acute attack of bronchial asthma, severe airway spasms can occur, leading to a situation where the patient might not have any wheezing sounds, a condition referred to as "silent lung." In such cases, patients often experience difficulty breathing or even respiratory distress, which is usually quite serious and requires active intervention.
What should I do if I have a heavy nasal voice due to a cold?
Cold with nasal voice, in most cases, does not require special treatment. A cold can cause symptoms such as runny nose, sneezing, nasal congestion, sore throat, and coughing. These symptoms can lead to a nasal voice in patients, and this condition usually does not require special treatment. If the symptoms of runny nose, sneezing, and nasal congestion are particularly severe and affect the patient's daily life, some compound cold medicines can be used to alleviate the symptoms, such as compound cold medicines like Ammaminamide tablets. Additionally, for a heavy nasal voice due to a cold, it is also necessary to assess the patient's condition. If the patient has a lot of purulent nasal discharge and is accompanied by headaches, it is important to be alert to the possibility of sinusitis, which also needs to be treated. (Please use medication under the guidance of a doctor.)
Does tuberculous pleuritis belong to pulmonary tuberculosis?
Tuberculous pleurisy is not classified as pulmonary tuberculosis. Tuberculous pleurisy is a common manifestation of extrapulmonary tuberculosis, often referred to as tuberculosis of the pleura, typically presenting with pleural effusion. Symptoms can sometimes include low-grade fevers in the afternoon and night sweats, which are typical of tuberculosis intoxication. However, the clinical presentation of tuberculous pleurisy can sometimes be atypical, with some patients experiencing high fevers, and there are cases of tuberculous pleurisy without any fever. Additionally, tuberculous pleurisy often coexists with pulmonary tuberculosis. Sometimes, patients with tuberculous pleurisy who undergo a chest CT scan may find lesions in the lungs, but there are also cases where tuberculous pleurisy may exist independently, without the presence of pulmonary tuberculosis.
Does increased lung markings indicate tuberculosis?
Increased pulmonary markings are not an exclusive indicator of tuberculosis. The increase in pulmonary markings could be a sign of acute bronchitis or chronic pulmonary congestion. Additionally, although patients with bronchiectasis often show characteristics in a chest CT, it might only appear as increased pulmonary markings in a chest X-ray. Tuberculosis can present in various forms of lesions, often coexisting in multiple forms. Such forms may include infiltrative lesions, fibrous strip-like lesions, nodular lesions, or even lesions with calcification. For diagnosing tuberculosis, relying solely on chest X-rays or CT scans is sometimes insufficient. Further confirmation often requires additional tests such as sputum acid-fast staining and bronchoscopy.
Difference between acute upper respiratory tract infection and upper respiratory tract infection
In clinical terms, acute upper respiratory infection and upper respiratory infection usually mean the same thing, and there is no significant difference between them. Upper respiratory infections are typically acute, so sometimes they are simply referred to as upper respiratory infections without specifically mentioning 'acute.' Acute upper respiratory infections and upper respiratory infections generally have no difference; patients are often infected by viruses, typically presenting symptoms such as runny nose, sneezing, sore throat, coughing, and sometimes accompanied by fever. There may also be associated muscle soreness, fatigue, and headaches, but patients often experience low-grade fever rather than high fever. For these issues, symptomatic treatment is usually needed, and through such treatment, patients often recover on their own.
Is pulmonary fibrosis always caused by tuberculosis?
Pulmonary fibrosis foci do not necessarily result from tuberculosis, although tuberculosis is a relatively common cause of such fibrosis. After tuberculosis is cured, pulmonary fibrosis foci may remain. However, in cases of general pulmonary inflammation, sometimes the lesion is not completely absorbed, which may also result in fibrosis. If the pulmonary fibrosis foci are a result of tuberculosis, there is a certain risk of recurrence. In such cases, measures should be taken to prevent recurrence, such as ensuring balanced nutrition and engaging in appropriate exercise to enhance one's resistance. These measures help prevent the recurrence of tuberculosis. Additionally, pulmonary fibrosis foci can also lead to changes in lung structure, making patients relatively more susceptible to respiratory infections. Therefore, for pulmonary fibrosis foci, it is also important to keep warm and prevent respiratory infections.
Is bacterial cold serious?
Bacterial colds are generally not severe and typically manifest symptoms such as sore throat and fever. Active anti-infection treatment is necessary, along with adjunctive non-pharmacological measures like a light diet and adequate hydration, which usually help control the condition. However, it is important to note that even bacterial colds require standardized treatment, as neglecting this can increase the risk of complications such as pneumonia. Additionally, in pediatric patients, bacterial colds caused by streptococcal infections can lead to severe complications like nephritis. Therefore, more aggressive treatment is crucial for children with bacterial colds to avoid delaying treatment and preventing potential complications.
