What should I do about dry cough and wheezing caused by lung cancer?
Patients with lung cancer presenting with dry cough and wheezing often require treatment to suppress coughing, alleviate wheezing, and address the symptoms. It is also important to check if the patient has concurrent obstructive pneumonia. Lung cancer combined with obstructive pneumonia can also lead to dry cough and wheezing. In such cases, anti-infection treatment is needed, along with treatment specifically targeting lung cancer itself. Dry cough and wheezing in lung cancer often suggest that the cancer may be in the middle to late stages, where the chances of surgery are generally small. However, it is still necessary to complete relevant examinations to further assess the condition. If the patient is eligible for surgery, surgical treatment should be considered. If the patient is indeed in the middle to late stages of lung cancer and is not suitable for surgery, chemotherapeutic drugs are needed for treatment. Sometimes, targeted drugs can be chosen for treating advanced-stage non-small cell lung cancer. In cases of advanced non-small cell lung cancer with driver gene mutations, targeted therapy might even be the preferred treatment option.
The difference between bronchitis and tracheitis.
Bronchitis and tracheitis are not standardized diagnoses. For bronchitis, it often refers to acute bronchitis, while tracheitis often refers to chronic bronchitis. Acute bronchitis is an infectious respiratory disease, which mostly presents with symptoms of coughing, and may also be accompanied by sputum production and chest tightness. However, the condition of the patient is usually completely curable. Chronic bronchitis, on the other hand, is a chronic respiratory disease. This condition can manifest as chronic cough, sputum production, and chest tightness, and the patient's condition may progress gradually, even possibly complicating with chronic respiratory failure and cor pulmonale. Therefore, chronic bronchitis and acute bronchitis are two completely different diseases. Additionally, it is important to note that sometimes bronchitis may also refer to chronic bronchitis, and tracheitis may also refer to acute bronchitis, so it is impossible to completely distinguish between bronchitis and tracheitis.
Can a pulmonary embolism be detected by an X-ray?
Pulmonary embolism cannot be detected by X-ray. Although in rare cases, some signs might appear on an X-ray, such as localized sparse lung markings, these signs are typically not characteristic. For conditions like pulmonary embolism, color Doppler ultrasound can be used to assist in diagnosis. If the ultrasound suggests deep vein thrombosis in the legs along with pulmonary hypertension, it indicates a high possibility of pulmonary embolism. Additionally, testing for D-dimer and blood gas analysis can also help in diagnosing pulmonary embolism. CT pulmonary angiography can also be used to diagnose the condition. CT and pulmonary angiography have a high diagnostic value for pulmonary embolism, and most cases can be definitively diagnosed through these tests.
Pleurisy is caused by what?
Pleurisy is often caused by various pathogens, such as viral infections, which can lead to pleurisy termed viral pleurisy. Viral pleurisy typically presents with noticeable chest pain, and may even be accompanied by tenderness in the chest wall. Similarly, bacterial infections can also cause pleurisy. If the infection is a purulent bacterial infection, it is known as purulent pleurisy. Generally, those with purulent pleurisy experience high fever symptoms. Another common cause of pleurisy is tuberculosis infection, known as tuberculous pleurisy. Typical symptoms of tuberculous pleurisy include low-grade fever in the afternoon, night sweats, and may also include chest tightness and chest pain.
Can acute bronchitis drink alcohol?
For acute bronchitis, it is generally not recommended to drink alcohol. Patients with acute bronchitis are advised to consume a light diet, avoiding spicy, irritating, and greasy foods, and to refrain from drinking alcohol, coffee, and strong tea. Patients with acute bronchitis, especially those who consume large amounts of alcohol, may experience a decrease in immunity and can even develop complications like pneumonia. Sometimes, acute bronchitis can also be accompanied by bacterial infections, and patients might need to take oral antibiotics for treatment. If a patient with acute bronchitis takes cephalosporin antibiotics, it is absolutely necessary to avoid alcohol, as alcohol can interact with cephalosporins and potentially trigger a disulfiram-like reaction, which in severe cases can lead to sudden stopping of breathing and heart function, posing a life-threatening risk. (Please use medication under the guidance of a doctor.)
Can people with bronchial asthma eat persimmons?
Patients with bronchial asthma can generally eat persimmons, as bronchial asthma is not a contraindication to eating persimmons. However, it should also be noted that some patients with bronchial asthma may have a highly sensitive constitution and may be allergic to various foods and fruits. For instance, in rare cases, some patients with bronchial asthma may be allergic to persimmons, and eating them can lead to rashes, itchy skin, or even worsen symptoms such as chest tightness. If a patient with bronchial asthma has a confirmed allergy to persimmons, then they should avoid eating them. Additionally, patients with bronchial asthma need to be observant of their condition when eating certain foods, including persimmons. It is important to observe whether the patient develops rashes, itchy skin, chest tightness, or other related symptoms. If such symptoms occur, it suggests an allergic reaction to persimmons, and the patient should stop eating them.
Can people with bronchial asthma eat crab?
Patients with bronchial asthma are not absolutely prohibited from eating crabs, but they should be cautious when doing so. Those with bronchial asthma might be allergic to certain foods, potentially triggering an acute asthma attack, or even severe asthma due to food allergies, which could be life-threatening. Seafood is one of the most common triggers for such allergies. Therefore, it is generally advised for patients with bronchial asthma to avoid seafood. Additionally, foods like fish, shrimp, and crabs can also cause allergies. Thus, patients with bronchial asthma need to be cautious when eating crabs, especially if they have never eaten them before. If they do eat crabs, it should be tried in small amounts. If symptoms such as rash, itchy skin, coughing or chest tightness occur during the consumption of crabs, they should immediately stop eating and, if necessary, appropriate medication should be administered.
What are the symptoms of pleurisy?
Common symptoms of pleurisy include chest pain, which often worsens with deep breathing. This condition is also called pleuritic chest pain. It is important to note that the presence of such chest pain does not necessarily indicate pleurisy; it could also be due to pneumonia, pulmonary embolism, or even rib fractures. Patients with pleurisy may also experience a sensation of chest tightness, especially when there is a significant amount of pleural effusion. Furthermore, severe chest pain caused by pleurisy may lead to patients avoiding deep breaths, which can also result in symptoms of chest tightness. Fever is another common symptom in patients with pleurisy, and the severity of fever can vary depending on the infection causing the pleurisy. For example, tuberculous pleurisy, caused by tuberculosis infection, often results in a low-grade fever in the afternoon, but high fevers can also occur. In the case of purulent pleurisy, which is usually due to a bacterial infection leading to pus formation in the pleural cavity, high fevers are common.
What should I do if I have a cold and a sore throat?
In cases of colds with sore throats, appropriate measures should be taken based on the specific condition. A cold with a sore throat may be caused by a viral infection. For viral colds, there are usually no specific treatments, and symptomatic pain relief treatment is often needed, along with adequate hydration and proper intake of fruits and other related measures. Additionally, a sore throat from a cold could also be a bacterial infection, such as acute purulent tonsillitis, which is a type of bacterial cold. Patients with acute purulent tonsillitis often experience significant throat pain, swollen tonsils with purulent secretions on the surface, and may also have a fever. For acute purulent tonsillitis, not only is symptomatic treatment necessary, but also the use of sensitive antibiotics is required.
Can pulmonary embolism cause bloating and abdominal distension?
Pulmonary embolism can, in rare cases, cause bloating and abdominal distension. The primary clinical manifestations of pulmonary embolism are chest tightness and difficulty breathing. Severe pulmonary embolism can also lead to a drop in blood pressure and sometimes may even cause the patient to faint. However, it is important to note that in severe cases of pulmonary embolism, patients may also experience abdominal distension. Patients with pulmonary embolism might also have acute pulmonary heart disease, which could include symptoms of gastrointestinal congestion. In such cases, patients may experience abdominal bloating. Additionally, there is a special condition known as chronic thromboembolic pulmonary hypertension, where patients may experience chronic pulmonary heart disease and chronic hypoxia, which can also lead to abdominal distension.
