There are many yellow bubbles on the throat wall

The most common discomfort symptoms in our throat are redness, swelling and pain. However, some friends, for unknown reasons, have many yellow bubbles growing on the throat walls. After going to the hospital for examination, they found that they were suffering from pharyngitis. In fact, pharyngitis is mainly caused by weak resistance or bacterial infection. Generally speaking, medication can provide relief. Let us now take a closer look at the disease of pharyngitis.

Pharyngitis is an acute inflammation that occurs in the pharyngeal isthmus and is a special type of pharyngitis. The pharyngeal isthmus refers to a ring-shaped structure on the vertical plane of the pharynx. The upper part is the uvula and the free edge of the soft palate on both sides, the lower part is the root of the tongue, and the left and right sides are the palatoglossal arch and palatopharyngeal arch. These four structures together form a narrow annular part called the pharyngeal isthmus. Pharyngitis can be caused by bacteria, viruses and other pathogens, and manifests as sore throat, dry throat, foreign body sensation, herpes, ulcers, etc., which are similar to the symptoms of acute tonsillitis.

There are several specific types of pharyngitis. ① Herpetic pharyngitis in children is mainly caused by infection with enterovirus Coxsackie group A virus. Characterized by acute onset of fever and sore throat, red halos on the mucosa and characteristic surrounding vesicular rash; ② Vincang pharyngitis, also known as ulcerative pharyngitis or ulcerative tonsillitis, is a subacute tonsillitis caused by infection with Fusobacterium and Vincang Borrelia, characterized by obvious localized inflammatory reaction and ulcer formation.

Causes

It is often part of an upper respiratory tract infection but can also occur alone. It often occurs in autumn and winter and between winter and spring.

1. Viral infection

Coxsackievirus, adenovirus, and parainfluenza virus are the most common, and are mostly transmitted through droplets and close contact.

2. Bacterial infection

The main bacteria are streptococci, staphylococci and pneumococci, as well as fusobacteria and others. If bacteria or toxins enter the blood, purulent lesions may even occur in distant organs.

3. Other pathogens

Spirochete, etc.

4. Causes

Many pathogens are conditional pathogens, which usually coexist in the oral cavity of healthy people without causing disease. However, when the body's resistance is reduced, such as due to excessive fatigue, malnutrition, excessive stress, depression, poor environmental hygiene, vitamin deficiency, gastrointestinal diseases, unclean mouth, caries, cachexia, blood disease, poisoning, etc., this disease can be induced. It can also be transmitted through sharing eating utensils.

Herpetic pharyngitis is more common in children aged 3 to 10 years old, and is more common in summer and autumn. The disease may occur multiple times in the same patient, each time caused by a different type of virus. The incubation period is 3 to 10 days. It usually starts with a sudden high fever, which can reach a peak within 24 to 48 hours, rising to 39 to 41°C, accompanied by headache, throat discomfort, myalgia, etc. Infants and young children often vomit, refuse to eat, and even have febrile convulsions. However, most of them are mild cases, which are self-limited and improve in 1 to 2 weeks.

examine

Examination revealed obvious congestion of the pharyngeal isthmus, and edema of the soft palate and uvula was partially visible. The submandibular lymph nodes are swollen and tender.

In children with herpetic pharyngitis, red halos can be seen on the back of the soft palate, pharynx, tonsils, etc., surrounded by characteristic vesicles or white papules (lymph nodes).

People with Fan Shang's pharyngitis often have bad breath and thick tongue coating. The lesions are usually confined to one tonsil but may also involve the palatine arch, gums and pharyngeal wall. The lesion is covered with a thick and dirty pseudomembrane, which is yellow or grayish white and is composed of necrotic material of the ulcer. It is easy to wipe off, and there are small bleeding spots on the ulcer surface after wiping.

If the total white blood cell count and neutrophil count in a routine blood test are elevated, it indicates a bacterial infection. If not, it may be a viral infection.
