• Inadequate diagnosis 
• The lack of a comprehensive program of 
monitoring of the patients 
• The lack of continuity of treatment in the hospital 
and continuing of treatment on an outpatient basis 
• The need for rehabilitation and social adaptation

• Symptom complex of BOS: obstructive bronchitis, 
bronchitis caused by atypical flora (chlamydia, 
mycoplasma), asthma, cystic fibrosis and other 
pathological conditions have close clinical, diagnostic 
and therapeutic parallels between them.

1. Bronchoobstructive syndrome (BOS) is a symptom 
complex associated with impaired bronchial patency 
of functional or organic origin.

• In Western literature this clinical symptom complex is 
currently called wheezing - wheezing syndrome.
• The term "BOS" can not be used as an independent diagnosis. 
BOS is a symptom complex of any disease, the etiology of 
which is necessary to determine in all cases of the 
development of bronchial obstruction.

• The prevalence of obstructive conditions of the airways is quite high, 
especially in children during the first 6 years of life which is associated 
with anatomico-physiological features of the respiratory tract in infants.
• Prevalence of BOS on the background of respiratory infections in infants 
ranges from 5% to 50%.
• Most often obstructive conditions occur in children with a family history of 
allergies, as well as in children, who often suffer from respiratory 
infections (more than 6 times).
