What should be avoided in the diet for acute tonsillitis?
Acute tonsillitis is primarily caused by an acute infectious inflammation of the tonsils due to bacterial infection, which may also initially involve viral infections. The main bacteria involved are Staphylococcus aureus and hemolytic streptococcus. The dietary restrictions for acute tonsillitis mainly include the following: Firstly, in terms of diet, it is important to eat light, nutritious, and easily digestible foods. Spicy and stimulating foods such as tobacco and chili peppers should be avoided, as these irritants can cause further congestion and swelling of the mucous membranes, exacerbating the condition during the acute phase. Secondly, attention should be given to substances such as mangoes and seafood, which can cause allergies. If a patient is allergic to these substances, consuming them can trigger allergic symptoms, aggravating the clinical symptoms of acute tonsillitis and worsening the condition. Thirdly, it is important to ensure that the food consumed is neither too hot nor too cold, as extreme temperatures can affect the recovery from the illness.
How is acute otitis media treated?
Acute otitis media is caused by bacterial infection. It is an infectious inflammation of the middle ear chamber, eardrum, or mastoid cavity. Since it is a bacterial infection, the primary treatment choice is anti-infection therapy, specifically the use of antibiotics. Currently, in clinical practice under the guidance of a doctor, cephalosporin antibiotics are mainly used. At the same time, certain antibiotic ear drops should not be used, such as ofloxacin ear drops and lomefloxacin ear drops, especially in cases of acute otitis media with severe symptoms like fever and headache. Based on the condition, we also consider anti-infection treatment through infusion. Infusion refers to the intravenous use of cephalosporin antibiotics, among others. Additionally, some corticosteroids can be used to enhance the anti-infection effects.
How to treat a deviated nasal septum?
Deviated nasal septum refers to the deviation of nasal septum cartilage and bone tissues towards one or both nasal cavities, causing symptoms such as nasal congestion, nosebleeds, and even headaches. Generally speaking, when these symptoms of nasal septum deviation occur, surgical treatment is typically adopted. This involves correcting and removing the deviated cartilage and bone tissues under endoscopic guidance to restore normal airflow in the nasal passages. If a patient only has structural or radiographic evidence of a deviated nasal septum but lacks clinical symptoms, surgery may not be necessary. Alternatively, temporary observation and medical management to control inflammation of the nasal mucosa can be considered.
Can nasal polyps be felt by touch?
Nasal polyps are benign neoplasms that occur in our nasal cavity. Clinically, nasal polyps in their early stages are primarily located in the middle nasal passage. As the nasal polyps enlarge, they can also be found in the middle nasal passage, and severe ones might even protrude from our anterior nostrils onto our face. Thus, for larger nasal polyps, we can physically feel them; they feel very soft and not very elastic. However, they are somewhat resilient and can move significantly because most nasal polyps are pedunculated within our nasal cavity. Additionally, there is often a lot of nasal mucus.
How is nasal polyps treated?
Nasal polyps are a common clinical condition, prevalent in the nasal and sinus cavities as benign space-occupying lesions. Clinically, these polyps appear as translucent, lychee-like neoplasms. The primary clinical treatment for nasal polyps is surgical, typically performed with an endoscope to remove the polyps, mainly using a powered system. After nasal polyp surgery, the treatment is not completely finished; regular outpatient follow-ups are necessary to infiltrate the nasal and sinus cavities and remove some of the swollen mucosal tissue, thus preventing the recurrence of nasal polyps.
Is acute pharyngitis contagious?
Acute pharyngitis is an acute infectious inflammation of the pharyngeal mucosa, submucosal tissue, and local lymphatic tissue. Acute pharyngitis can occur independently or as part of an upper respiratory tract infection. In its early stages, acute pharyngitis is primarily a viral infection, or a mixed infection of viruses and bacteria. In the later stages of acute pharyngitis, bacterial infection often occurs secondarily. Acute pharyngitis is contagious and tends to occur mainly in winter or spring. The contagion is not by reverse transmission but is generally infectious. Wearing masks or avoiding close contact can generally prevent it, and special isolation measures are usually unnecessary for prevention.
Can pharyngitis cause coughing?
Pharyngitis refers to the inflammation of the mucous membrane of the pharynx. There are many clinical causes of pharyngitis, such as allergic pharyngitis, reflux pharyngitis, and infectious pharyngitis. Regardless of the type, pharyngitis can lead to clinical symptoms such as coughing and throat clearing actions, especially intense dry coughs in allergic pharyngitis, which tend to last a long time. For infectious pharyngitis, the coughing duration is short and the coughs are less intense. Therefore, it is certain that pharyngitis can cause coughing. Clinically, different types of medication are used to treat coughs caused by different types of pharyngitis. For coughs caused by allergies, anti-allergy treatments are required, and for coughs caused by reflux pharyngitis, medications that suppress stomach acid are needed.
What causes rhinitis?
There are many causes of rhinitis in clinical settings, such as acute rhinitis, which is primarily due to infections, especially viral infections. Chronic rhinitis has many influencing factors, such as incomplete treatment of acute rhinitis leading to chronic conditions, or originating directly from chronic rhinitis. For instance, physical and chemical irritants, inappropriate use of medications in the nasal cavity, such as rhinitis medicamentosa caused by the use of nasal mucosa constrictors, and some inappropriate self-actions like habitual nose-picking, can all cause chronic rhinitis. Other forms of rhinitis, such as allergic rhinitis, are mainly caused by allergic factors. There is also vasomotor rhinitis, mainly due to inconsistent vasoconstriction, among other reasons. These are the main factors. (For specific medications, please follow the guidance of a professional physician and do not medicate blindly.)
Is a hemangioma in the nose dangerous?
Nasal hemangiomas are primarily caused by congenital or acquired vascular malformations. The risks associated with them include the following points: First, the vessel walls of hemangiomas are imperfect and prone to bleeding. Excessive bleeding can lead to hemorrhagic shock. Furthermore, significant bleeding can cause blood to flow back into the respiratory tract, leading to coughing fits and even the risk of suffocation. Second, although hemangiomas are benign in nature, a few of them possess the biological characteristic of expansive growth. This characteristic can damage surrounding tissues, such as destroying the wall of the vessel and the structure of the tumor, thereby exhibiting malignant-like biological behavior. Therefore, active treatment is necessary.
"What is allergic rhinitis allergic to?"
Allergic rhinitis is a type of pathological reactive disease that occurs in the nasal area. The allergens of allergic rhinitis usually require examination, and there are many methods of examination, such as skin prick tests, hat tests, etc. According to the epidemiological survey of allergens for allergic rhinitis, the main allergens include allergies to dust mites, pollen, and ragweed. In the eastern coastal regions, allergies to dust mites are more common, while in the north and west, allergies to ragweed are more frequent. During the spring season, pollen allergies are relatively common.
