Bronchogenic - inflammatory process in the lymph nodes adjacent to the bronchi, trachea, and located in the mediastinum. Increased intrathoracic lymph nodes in children, detected mainly radiographically, you can meet with pneumonia, measles, whooping cough, acute and chronic diseases of nasopharynx. As an independent form of the disease bronchogenic is tubercular etiology.
Conditionally TB bronchogenic divided into inflammatory (infiltrative and granulomas (rumoroso) form. The latter is common in young children. Beginning of the disease is usually acute. There are common symptoms of tuberculosis intoxication (see Tuberculosis, peculiarities of the course in children). In children of early age sometimes experience symptoms compression mediastinum: bitonal, rarely coloradony cough, expiratory stridor (whistling noise during exhalation). Blood changes similar selected at primary tuberculosis complex. Radiographically detected the increase of the size of the root of the lung, when tumorosan bronchogenic - isolated shadow of the sentinel lymph node. Characteristic of unilateral lesion. More precise information can be obtained at tomography (see) and bronchoscopy. Diagnosis is confirmed by a positive tuberculin responses (see Tuberculosis tuberculin), the discovery in the lavage of the stomach and bronchus Mycobacterium tuberculosis. To differentiate you from nonspecific bronchodilator with acute infectious diseases, pneumonia, chlamydia, enlarged thymus gland.
With timely early treatment prognosis is good. With a massive caseous bronchodilator possible perforation of the bronchi and education of atelectasis. In children of early age TB bronchogenic severe than the older, and often complicated by the hematogenous generalization and meningitis. In the reverse process of the development of patients developing the syndrome of chronic tuberculosis intoxication.
Treatment: antibiotics (streptomycin, tubazide and PAS), usually held in the hospital for a long time, within 10-12 months. Daily dose of the following drugs: streptomycin children up to 3 years - 0,2-0,25 g, from 4 to 7 years - 0.25-0.3 g, from 8 to 12 years - 0.3-0.5 g; children up to tubazide 3 years - 0.1 g, from 4 to 7 years - 0.25 g, from 8 to 12 years - 0.45 g; PAS children up to 3 years, 1.5 - 2 g, from 4 to 7 years 4 g, from 8 to 12 years - 6, the Food should be high in proteins and vitamins (fresh vegetables and fruit). After remitting the process activity of the child should be sent to the sanatorium to full clinical recovery. Cm. also Tuberculosis.
