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.
How long after sinusitis surgery should a follow-up be conducted?
Sinusitis, which we now generally refer to as sinusitis, is diagnosed based on specific examinations and surgical interventions are considered when indicated. After surgery, regular follow-ups are necessary, along with nasal cavity cleaning to prevent the recurrence of sinusitis. Typically, after discharging the surgical patient, we advise them to return to the clinic for a follow-up after a week. Subsequently, based on specific conditions during the follow-up, patients are instructed to return for further check-ups after two weeks, four weeks, eight weeks, and even up to three months. This process should continue for about half a year, during which regular clinic visits for follow-ups are necessary. During these visits, the doctor will assess the healing of the sinus cavity and schedule the next follow-up appointment accordingly.
Malignant treatment methods for laryngeal cancer
Laryngeal cancer is a malignant tumor of the larynx, clinically mainly squamous cell carcinoma. The treatment method for laryngeal cancer should be based on the patient's age, the pathological type of the patient, the extent of the malignant tumor, and the presence or absence of systemic metastasis. Clinical treatments mainly focus on surgery, combined with radiotherapy and chemotherapy, as comprehensive treatment methods. There may be some differences in surgical approaches for different types of laryngeal cancer, such as total laryngectomy or partial laryngectomies, which can be vertical or horizontal. Therefore, treatment should be tailored to the specific conditions of the patient. In late-stage laryngeal cancer, only palliative symptomatic treatment can be performed.
Can adenoid hypertrophy be prevented by vaccination?
Enlarged glands can lead to sleep apnea, snoring, decreased hearing, and secondary sinus infections. If the enlargement is simple without these symptoms, it does not affect vaccination. However, if the enlargement leads to acute sinus infection, manifested by chills, fever, a large amount of thick nasal discharge, or pus-like discharge, these are symptoms of an acute infection, and vaccination should not be administered. Appropriate treatment should be given first, and after the condition is controlled, vaccination can then proceed. Simple adenoid hypertrophy does not impact vaccination.
How long after vocal cord polyp surgery can one eat normally?
Vocal cord polyps are mucous-like formations on the vocal cords. Clinically, vocal cord polyps are primarily removed through surgery. These polyps are benign lesions located in the vocal fold area, not in the digestive tract or the pharynx, therefore, they do not affect eating or swallowing. After surgery for vocal cord polyps, a patient can normally eat four to six hours after waking from general anesthesia. However, care must be taken not to cough violently while eating, and spicy or irritating foods should be consumed less or avoided altogether. This does not mean that one cannot eat normally after surgery for vocal cord polyps.
How to treat granulation in otitis media?
Granulation tissue proliferation in otitis media indicates an active phase of inflammation. In clinical treatment, the first approach is medication, mainly using antibiotics and hormones, with both local and systemic applications of these drugs concurrently. Treatment usually lasts about two weeks. Generally, most granulations in otitis media are relatively small and can gradually shrink or even completely disappear with such medication. For granulations that fill the middle ear and tympanic cavity, if they cannot be reduced or controlled effectively through medication, then surgical intervention is necessary to remove the granulations in the middle ear cavity and thus treat the otitis media.
