Contact dermatitis
Contact dermatitis is an inflammatory skin condition caused by contact with allergens or irritants, often occurring on exposed body parts. It is not contagious and not life-threatening. The main symptoms include erythema, papules, vesicles, and even bullae, accompanied by severe itching.
View detailsShock
Shock refers to a series of symptoms caused by various pathogenic factors, such as trauma, infection, and allergies, which lead to a reduction in effective systemic circulating blood volume and insufficient blood in the microcirculation. This prevents oxygen and nutrients from being effectively transported to tissues and organs, and metabolic waste products from being removed, ultimately resulting in ischemia and hypoxia of tissue and organ cells. In the early stages of shock, patients experience thirst, pale skin and mucous membranes, and anxiety, but their consciousness remains relatively clear. As the condition progresses, symptoms such as altered mental status, decreased skin temperature, rapid heart rate, and reduced urine output begin to appear.
View detailsPediatric allergic rhinitis
Pediatric allergic rhinitis, also known as pediatric allergic rhinitis, is a non-infectious inflammatory disease of the nasal mucosa that occurs in children after exposure to allergens such as dust mites and pollen. The main symptoms of this disease include nasal itching, sneezing, clear runny nose, and nasal congestion.
Anaphylactic shock
Anaphylactic shock refers to a severe immune reaction triggered by certain allergens entering the body of susceptible individuals, leading to a syndrome affecting multiple internal organs within a short period. It is common in young people and manifests as skin rash, difficulty breathing, and decreased blood pressure.

View detailsHay fever
Hay fever, also known as allergic rhinitis, is primarily caused by an allergic reaction to plant pollen, affecting the eyes, nose, respiratory tract, and skin. It is common in children aged 8-16 years. Main symptoms include an itchy throat, red, itchy, and watery eyes, runny nose, nasal congestion, sneezing, wheezing, or coughing.
View detailsNucleic acid test
Nucleic acid testing uses molecular biology techniques (such as real-time fluorescent polymerase chain reaction, isothermal amplification, in situ hybridization, sequencing, etc.) to detect pathogenic nucleic acids in various body fluid or tissue samples to determine whether a pathogen infection has occurred. Nucleic acid testing is also applied in the diagnosis and treatment of genetic diseases, tumor molecular typing, and other fields. Based on different sampling routes, common clinical methods for nucleic acid collection mainly include oropharyngeal swabs and nasopharyngeal swabs, which are suitable for most people. In addition, depending on clinical needs, there are also anal swabs and blood draws (serological) for nucleic acid testing. Compared with oropharyngeal swabs, nasopharyngeal swabs stay in place for a longer time during sampling. In the detection of pathogens such as influenza and coronaviruses, nasopharyngeal swabs have a higher positive rate than oropharyngeal swabs, and a lower false negative rate.
View detailsDiphtheria
Diphtheria is an acute respiratory infectious disease caused by Corynebacterium diphtheriae, classified as a Class B infectious disease. It is most common in children under 15 years of age and is a very serious bacterial infection that was once a major cause of illness and death in children. The disease is mainly characterized by the appearance of white pseudomembranes in the pharynx, tonsils, and surrounding tissues, as well as symptoms of systemic toxemia. In severe cases, it can be complicated by myocarditis and peripheral neuritis.
View detailsEpstein-Barr virus infection
EB virus infection means infection with the Epstein-Barr virus (EBV). EBV is a member of the Lymphocryptovirus genus within the Herpesviridae family. It is the causative agent of infectious mononucleosis and is closely associated with the development of nasopharyngeal carcinoma and childhood lymphoma, being classified as one of the human tumor viruses potentially causing cancer. This disease commonly affects children and adolescents, but adults can also be infected. Common symptoms include headache, fatigue, fever, loss of appetite, nausea, vomiting, diarrhea, generalized lymphadenopathy, hepatosplenomegaly, and rash.
