Acute pharyngitis, acute tonsillitis, chronic pharyngitis and chronic tonsillitis are common inflammatory diseases. Acute pharyngitis is an acute inflammation of the pharyngeal mucosa, submucosal tissues and their lymphoid tissues, often as part of an upper respiratory tract infection. It can occur alone or secondary to acute rhinitis. It occurs mostly in autumn and winter and at the turn of winter and spring. Etiology】 1, viral infection Coxsackie virus adenovirus, parainfluenza virus caused by the most common, the virus through droplets and intimate contact and transmission. 2, bacterial infection Streptococcus, Staphylococcus and S. pneumoniae are the main ones, among which group A type B streptococcus causes more severe symptoms. 3, physical and chemical factors such as high temperature, dust, smoke, irritating gases, etc. In young children, acute pharyngitis is often the first symptom or accompanying symptoms of acute infectious diseases, such as measles, scarlet fever, influenza, rubella, etc. In adults and older children, it is often followed by acute rhinitis and acute tonsillitis. Cold, fatigue, excessive smoking and alcohol consumption, and a decrease in systemic resistance are all triggers for this disease. Clinical manifestations] The onset of the disease is rapid, with a dry, burning pharynx at the beginning. The pain is often more pronounced when emptying the throat than when eating, and the pain can be radiated to the ear. The systemic condition is generally mild, but the degree varies depending on age, immunity and virulence of virus and bacteria. Generally, the duration of the disease is about 1 week. Examination】 The mucosa of oropharynx and nasopharynx shows acute diffuse congestion, palatal arch and uvula edema, lymphatic follicles of posterior pharyngeal wall and lateral pharyngeal cord redness and swelling. In cases of bacterial infection, yellowish-white exudate may appear in the center of the lymphatic follicles of the posterior pharyngeal wall. The submandibular lymph nodes are enlarged and have pressure pain. Diagnosis】 Based on the history, symptoms and local examination, the diagnosis is not difficult. To clarify the causative factors, pharyngeal bacterial culture can be performed. Attention should be paid to whether it is a precursor or concomitant symptom of acute infectious diseases (such as measles, scarlet fever, influenza and pertussis), which is especially important in childhood. In addition, if pseudomembrane necrosis is present in the oral cavity, pharynx, or tonsils, blood tests should be performed to rule out blood disorders. Complications] It can cause otitis media, sinusitis, laryngitis, tracheobronchitis and pneumonia. If the pathogenic bacteria and their toxins invade the blood circulation, it can cause acute nephritis, rheumatic fever, sepsis and other systemic complications. Treatment】 1. If the infection is serious and the systemic symptoms are obvious, bed rest, more water and a liquid diet should be taken, antiviral drugs and antibiotics or sulfonamides and Chinese medicine preparations with antiviral and antibacterial effects should be used. 2, systemic symptoms are light or no, local treatment can be used. Compound borax solution with gargle, oral iodine tablets and silver yellow tablets, etc., 4 to 6 tablets per day. In addition, can also be used 1% to 3% iodine glycerin, 2% silver nitrate coated swollen lymphatic follicles of the posterior pharyngeal wall, has an anti-inflammatory effect. 3, traditional Chinese medicine Chinese medicine believes that this disease is mostly external wind-heat, it is appropriate to remove wind and detoxify the surface, clear heat and detoxify the toxin, with Yin Qiao San plus reduction, and can also use the six Shen Wan, etc..
