How should pharyngitis be treated?
Pharyngitis refers to the chronic inflammation of the mucosa and submucosa in the throat, which can extend to the lymphatic tissue around the pharynx. The causes of pharyngitis may include bacterial infection, viral infection, environmental factors, and the patient's diet and lifestyle habits. It may also be related to excessive use of the voice or excessive talking. Traditional Chinese medicine considers it a type of heat syndrome. Therefore, one should avoid spicy and irritating foods, avoid shouting loudly, drink plenty of water, gargle with salt water, maintain oral hygiene, and consume foods that clear heat, detoxify, strengthen the spleen, and stimulate the appetite. Avoid smoking, drinking alcohol, staying up late, and overheating. Under the guidance of a doctor or pharmacist, one may use some traditional Chinese medicines that clear heat and detoxify. If pharyngitis is accompanied by symptoms such as pain and fever, taking anti-inflammatory medications can enhance the treatment effect.
How to treat adenoid hypertrophy?
Adenoid hypertrophy mainly occurs in infants and children. It is a congenital disease, meaning that most children are born with varying degrees of adenoid hypertrophy. However, in many children, the adenoids begin to shrink after six months and generally do not cause symptoms. If the adenoids are enlarged, it can lead to the child breathing through their mouth, snoring, and gasping, which may cause facial changes, brain hypoxia, and delayed brain development. In such cases, adenoidectomy might be considered, generally performed under general anesthesia. However, some children with adenoid hypertrophy also have enlarged tonsils, so both surgeries are often performed together. Otherwise, if only the adenoid hypertrophy is treated without addressing enlarged tonsils, problems such as mouth breathing and snoring may not improve.
How to treat vocal cord nodules
Vocal cord nodules, also known as singer's nodules, are typically located at the junction of the anterior and middle thirds of both vocal cords, featuring symmetrical nodular protrusions. They are more commonly found in individuals who use their voices professionally, such as singers, teachers, or other vocations that involve frequent shouting, as well as in children. Prolonged or improper use of the voice is a major cause of this condition. Therefore, during treatment, voice rest is primarily advised. Early stage vocal cord nodules can spontaneously resolve with sufficient vocal rest, and nodules in children often disappear naturally during puberty. Additionally, medication can be used for treatment, such as traditional Chinese medicines, including Jin Sang San Jie Wan and Kai Yin Pills. If conservative treatment fails, surgical removal of the vocal cord nodules under fiberoptic laryngoscopy can be performed, followed by a two-week voice rest period. Post-surgery, it is recommended to inhale medicated vapors, avoid spicy and irritating foods, drink plenty of water, avoid staying up late, and refrain from excessive voice use or shouting.
Can nasopharyngeal carcinoma be treated with surgery?
Nasopharyngeal cancer is a malignant tumor in the nasopharynx, which is mainly found in coastal and Guangdong areas, and is more common among Mongoloid races. The treatment methods for nasopharyngeal cancer include radiotherapy, chemotherapy, and combined chemoradiotherapy. If the tumor does not disappear after combined chemoradiotherapy and is insensitive to drugs, surgery can be considered. Surgery is not the first-line treatment option for nasopharyngeal cancer; the first-choice treatments are radiotherapy and combined chemoradiotherapy, which are very effective and have a high five-year survival rate. If the cancer is insensitive to radiation and drugs, surgical treatment can be an option in such cases.
What bacteria cause suppurative tonsillitis?
Purulent tonsillitis primarily refers to an acute purulent inflammation of the tonsils, often accompanied by varying degrees of mucosal lymphatic tissue inflammation. The primary bacterium responsible for this condition is Group A beta-hemolytic Streptococcus, although non-hemolytic Streptococcus, Staphylococcus, Streptococcus pneumoniae, Haemophilus influenzae, as well as adenovirus, rhinovirus, and simplex herpes virus can also cause purulent tonsillopharyngitis. Mixed bacterial and viral infections are not uncommon, and in recent years, there has been an increase in yeast and Gram-negative bacilli infections. The pathogens of acute purulent tonsillitis can be transmitted via droplets or direct contact. Normally, some pathogens reside in the crypts of the pharynx and tonsils of healthy individuals. When the body's resistance is lowered, the pathogens proliferate extensively, and their toxins damage the crypt epithelium, allowing bacteria to invade the tissue and cause purulent changes. Factors such as exposure to cold, dampness, excessive fatigue, excessive smoking and drinking, and exposure to harmful gases can provoke this disease. Avoiding spicy and irritating foods, gargling with salt water, and maintaining oral hygiene are measures that can prevent or mitigate the occurrence of this condition.
Causes of Nasopharyngeal Carcinoma
Nasopharyngeal carcinoma is a highly prevalent malignant tumor in China, especially common in the Guangdong and Guangxi regions, as well as other coastal areas including Hunan, Fujian, and Jiangxi. These regions are among the highest incidence areas for nasopharyngeal carcinoma worldwide. The incidence rate in males is three times that of females, with the age group of 40 to 50 years being particularly at risk. The occurrence of nasopharyngeal carcinoma is associated with genetic, viral, and environmental factors, exhibiting racial and familial patterns. In areas like Guangzhou and the Pearl River Delta, it is possible for five out of nine people in the same family to have nasopharyngeal carcinoma. Infection with the Epstein-Barr virus is also one of the causes of nasopharyngeal carcinoma, in addition to environmental factors. Areas with low trace elements in rice and water, as well as low fluoride levels, are prone to higher incidences of this cancer. Patients with nasopharyngeal carcinoma typically have higher fluoride levels in their hair, and nitrites are also one of the major contributing factors to the condition.
What medicine is used for chronic rhinitis?
Chronic rhinitis refers to the chronic inflammation of the mucous membranes and submucosal layer inside the nasal cavity. It may be related to allergic states, bacterial infections, viral infections, environmental factors, and the dietary and lifestyle habits of the patient. In traditional Chinese medicine, it is considered a type of heat syndrome or a manifestation of having excessive internal heat. Therefore, it is important to avoid catching colds, avoid overexertion, and refrain from consuming spicy and irritating foods. One should also avoid smoking, drinking alcohol, and staying up late. Consuming some cooling foods that relieve heat and, under the guidance of a doctor or pharmacist, using some heat-clearing and detoxifying traditional Chinese medicines, as well as antihistamines and topical nasal corticosteroids, can be beneficial. Generally, with such treatment, rhinitis can be cured in about four weeks.
Early symptoms of vocal cord nodules
Vocal cord nodules, also known as singer's nodules, typically present as symmetrical nodular protrusions at the junction of the anterior and middle one-thirds of the vocal cords, with a relatively broad base. The main symptom is hoarseness of voice. Initially, the hoarseness is mild, characterized by a rough voice or nearly normal voice, such as when the voice is overused and feels fatigued, leading to intermittent bouts of hoarseness. Over time, the symptom of hoarseness worsens, progressing from intermittent to persistent hoarseness, affecting singers who cannot sing and teachers who are unable to teach. Examination with a laryngoscope may reveal small nodular protrusions on the anterior-middle one-third of the vocal cords, with incomplete closure of the glottis.
What are the symptoms of pharyngitis?
Pharyngitis refers to the chronic inflammation of the mucous membrane and submucosal layer of the pharynx, which can extend to the lymphatic tissue adjacent to the pharynx. Its causes are related to bacterial infections, viral infections, environmental factors, and the dietary habits of the patient. In traditional Chinese medicine, it is considered to be caused by excessive internal heat. Thus, symptoms of pharyngitis can include dry throat, a sensation of heat, a foreign body sensation, discomfort when swallowing, and an irritating cough. In severe cases, it might lead to pain, coughing, and expectoration of phlegm, which are some of the main symptoms of pharyngitis. Severe cases might also involve throat pain and swelling of the submandibular lymph nodes.
What are the symptoms of pharyngitis and influenza?
Pharyngitis influenza mainly involves inflammation of the mucosa or submucosal tissues of the pharynx, generally affecting the lymphatic tissue of the throat, primarily caused by viral or bacterial infections. Clinically, symptoms include dryness and a burning sensation in the throat, a rough feeling, and during severe cases, swallowing pain that may even radiate to the ear. If accompanied by systemic symptoms, such as acute inflammation, the symptoms may vary depending on age, immunity, and the virulence of the virus or bacteria. These symptoms can include fever, headache, decreased appetite, and limb soreness, which are all characteristic of pharyngitis, and during an acute attack, resemble symptoms of influenza.
