Infections and allergies are cyclic cause-effect relationships (a) Infections and allergies in children with chronic cough are mostly manifested by pan-infections and immune (immune) inflammatory reactions, with parents often complaining of “recurrent colds; low immunity” and specialists diagnosing “chronic recurrent rhinitis, laryngitis, peri-bronchiolitis, pneumonia, mycoplasma infection, cough variant asthma CVA”. Pan-infection and anti-inflammatory reactions are causally related and are mostly caused by internal/external factors (diet or feeding, environment) that disrupt the body’s own microbiota; in case of prolongation, a systemic disruption of the neurological/endocrine/immune network regulation occurs. It requires dynamic and careful observation of local respiratory symptoms and overall systemic manifestations, careful analysis to detect them, and doctor-patient communication. Laboratory tests, including multiple high-tech molecular biology assays (e.g., allergens, inflammatory immune indicators), chest CT, and pulmonary function are only auxiliary reference roles. (2) Current common misconceptions and problems: a. Parents (children): anxiety, fear of asthma, pneumonia, “root of the disease”, the pursuit of a definite diagnosis, the most famous doctors, looking for special drugs; lack of overall dynamic observation and analysis of the child; ignore the role of family atmosphere and environmental factors Beijing Children’s Hospital, Department of Infectious Diseases Chen Xiannan b. Doctors Aspects: simple mechanical diagnosis by routine blood, chest X-ray; simple or excessive reliance on drugs; c. Specific manifestations: (a) infants simple type diagnosis of pneumonia peri-bronchitis long-term repeated antibiotics, diagnosis of asthma single long-term nebulized aspiration resulting in oral upper airway phyla disorder; (b) children complex type: ignore psychosomatic (psychological, behavioral, habitual) comprehensive factors, one-sided to mycoplasma antibodies (currently quantitative determination of antibodies) (c) My thoughts and response ideas a. Refine the traditional concepts and classifications of infection, inflammation and allergy; avoid the mechanical static “infection/allergy? Differential diagnosis and treatment”. b. Refine integrated interventions and medication (person/time/place; physiological/psychological): alternate synergistic regulation of pan-infection/inflammation-free responses; c. Explore Internet medical intervention models: popularization of science, mother-to-mom exchange, physician participation, continuous refinement of symptom observation and doctor-patient communication. “”humidifier-related cough”; children’s psychological development – secrets of childhood: cough during sensitive periods; children’s chronic cough and mycoplasma infection: composition and evolution of mycoplasma antibodies; diagnosis and treatment patterns of children’s chronic cough and the doctor-patient relationship; diseases of children’s cough Positioning: psychosomatic disorders, subhealth states; TCM evidence-based thinking about chronic cough in children Lung heat/internal heat and damp heat; physical problems, etc.
