How to determine if a pulmonary embolism is acute or chronic?
Pulmonary embolism can be distinguished between acute and chronic based on the duration of the patient's illness, symptoms, and supplemental examinations. Typically, patients with acute pulmonary embolism have no prior similar symptoms and suddenly experience severe symptoms such as chest pain, difficulty breathing, and coughing up blood. Additionally, through supplemental examinations like blood tests, abdominal ultrasound, and pulmonary artery CT angiography, it is possible to determine whether the thrombus is fresh or old. In contrast, chronic pulmonary embolism often presents with prolonged symptoms. Patients usually do not experience chest pain or cough, and the main issue is chronic breathing difficulty. In severe cases, pulmonary heart disease may occur, and patients may have swelling in the face and limbs. Ultrasound and pulmonary artery CT angiography can reveal the characteristics of the thrombus, which differ from those seen in acute pulmonary embolism. Thus, these examinations can help determine whether the condition is acute or chronic.
Asthma cough symptoms
Asthma is a chronic airway inflammation involving multiple inflammatory cells. After being diagnosed with asthma, a patient may exhibit airway hyperresponsiveness. Upon exposure to allergens or cold stimuli, the patient often experiences wheezing, breathlessness, chest tightness, and coughing. These coughing symptoms generally worsen during the early morning and night, especially after exposure to odors or cold air, which can easily trigger coughing. The cough is primarily dry, without phlegm or with a small amount of white sticky phlegm, accompanied by symptoms like nasal itchiness, throat itchiness, and itchiness in the voice box. Treatment can involve the use of bronchial asthma medications or warm water, which can also lead to improvement. This describes some unique aspects of cough-variant asthma.
Does the flu cause vomiting?
Influenza refers to a group of diseases characterized by cough, sore throat, and fever following upper respiratory tract infection by influenza virus. However, influenza has its peculiarities. Apart from respiratory symptoms, influenza can also present with nausea, vomiting, and even abdominal pain and diarrhea. Thus, it is entirely possible for influenza patients to experience vomiting. However, due to some doctors' lack of understanding of influenza, the vomiting caused by influenza is often mistaken for acute gastroenteritis or treated as acute gastritis. This can lead to inappropriate medication use, resulting in prolonged illness. Therefore, if a patient has fever, nausea, vomiting, or sore throat, it is crucial to promptly consider the possibility of influenza to avoid delaying the diagnosis and treatment.
Can lungs be transplanted in the late stage of pneumoconiosis?
Pneumoconiosis can consider lung transplantation in its late stages. Lung transplantation, which is suited for end-stage lung diseases such as pneumoconiosis, pulmonary interstitial fibrosis, pulmonary hypertension, and even certain lung cancer patients can undergo this procedure. Regarding the current requirements for lung transplantation, the primary criteria include the patient’s overall condition meeting the standards for transplantation. Additionally, the function of other organs, apart from the lungs, must be maintained to a certain level to endure a lengthy surgery lasting 6-8 hours. If they cannot withstand this, there could be risks involved. Therefore, screening before lung transplantation is crucial. Moreover, as donor organs are relatively scarce, it is necessary to wait for the right opportunity to proceed with the transplantation.
How to test for allergens in allergic asthma
Allergic asthma is a subtype of bronchial asthma. As the name suggests, allergic asthma refers to asthma symptoms that are related to contact with external allergens, such as dust, pollen, dust mites, pet dander, etc. When these substances are inhaled into the trachea, they can trigger asthma symptoms. Clinically, when testing which substances a patient is allergic to, it is called allergen testing. Common methods include blood tests and skin prick tests, which can be combined for comparison to identify the allergens.
Why do patients with pulmonary embolism feel sleepy?
Patients with pulmonary embolism primarily suffer from emboli within the venous system, which travel back to the right heart and then become lodged in the pulmonary artery, forming a pulmonary artery thrombus. This reduces pulmonary blood flow and impacts the exchange of air in the lungs, leading to hypoxia in the patient. Following hypoxia, the brain tends to enter a sleepy state, thus many patients with pulmonary embolism exhibit sleepiness. This sleepiness is related to the pathophysiological mechanisms of pulmonary embolism. At this point, it is crucial to provide sufficient oxygen to the patient to address their hypoxemia. Ultimately, the most fundamental treatments are prompt thrombolysis or anticoagulation therapy to resolve the embolus, addressing the condition fundamentally.
Can the flu cause diarrhea?
Influenza can cause diarrhea, but this is a minority occurrence. Influenza is a disease that appears after the respiratory system of a human body gets infected with the influenza virus. After infecting the human body, influenza primarily manifests symptoms like coughing, sore throat, and fever. However, some patients may develop gastrointestinal symptoms such as diarrhea, nausea, and vomiting after being infected with influenza. This situation is related to viral infection, not the commonly thought stomach flu or food poisoning. Some patients may also experience joint pain and a decrease in appetite. If a patient experiences diarrhea accompanied by respiratory infection symptoms and has tested positive for influenza antibodies, it is necessary to promptly use antiviral drugs for influenza. However, many doctors who do not have such experience in diagnosing influenza might mistake the nausea and diarrhea caused by influenza for gastroenteritis, leading to a delay in proper treatment. Therefore, if one has respiratory symptoms accompanied by gastrointestinal symptoms, the possibility of influenza should be considered.
Sequelae of pleurisy with pulmonary effusion
The main sequelae of pleurisy with pleural effusion are pleural adhesions, which can affect respiratory function. Pleurisy is mostly caused by infectious diseases, although a portion is also due to non-infectious diseases. In the case of pleural effusion caused by infectious diseases, it contains a large amount of fibrinogen, which has the function of adhering to our pleura, thereby causing the pleura to thicken. At this time, the pleura will compress our lungs, significantly reducing the respiratory volume of our lungs, which greatly affects our respiratory function. Patients mainly exhibit symptoms such as shortness of breath, chest tightness, and rapid breathing even with slight activity or while lying in bed. Therefore, if pleurisy is detected, it is crucial to drain the fluid from the patient as soon as possible to avoid delaying treatment and the subsequent development of severe sequelae.
Routes of influenza transmission
Influenza, also known as the flu, is a disease caused by infection of the upper respiratory tract with the influenza virus. It is characterized mainly by sore throat, cough, and fever, and some patients may also experience nausea, vomiting, and diarrhea. The primary mode of transmission of influenza is through droplets, which occur when an infected person sneezes or coughs, and their secretions, such as nasal discharge, are inhaled by others. Additionally, the virus can be transmitted through the digestive tract and mucous membranes of the skin. If a healthy person comes into contact with the secretions of an infected person, such as through skin contact or orally, they may also be infected. Therefore, it is crucial to isolate from those infected with the flu.
Do acute upper respiratory infections require infusion?
Whether acute upper respiratory infections require fluid administration mainly depends on the patient's condition; the vast majority of acute upper respiratory infections do not require fluid administration. An acute upper respiratory infection, commonly referred to as a cold, is primarily caused by various pathogens, such as viruses or bacteria, infecting our upper respiratory tract, including the nose, pharynx, and larynx, which are commonly referred to as the upper respiratory tract. The symptoms of an upper respiratory infection mainly manifest as a runny nose, nasal congestion, cough, etc. For most people with normal immune function, young and middle-aged adults, or older adults in good health, upper respiratory infections can heal on their own, with or without medication. However, for some individuals in poor health, or older adults, an upper respiratory infection could potentially trigger heart failure, pneumonia, etc. Therefore, in these cases, some fluid therapy might be necessary, so the decision should be made based on the individual and specific medical condition, not arbitrarily applied across all cases.
