title: [Recurrent obstructive bronchitis in infants].
abstract: The study comprised 458 infants complaining of recurrent obstructive bronchitis from the clinical, chest X-rays and gastroesophageal reflux investigation view points. Spontaneous radiological reflux was found in 49.1% of the patients, although a history of vomiting was present only in 26.6%. In infants with positive radiological reflux, manometrics showed a shorter gastroesophageal sphincter and with lesser pressures than a group of normal infants. With medical treatment of the reflux, remission of the respiratory symptoms was seen in 63.5% of the patients. In a group of infants treated, control X-rays, and manometrics were practiced at the end of the medical treatment showing significant improvement of pressure and length of the gastroesophageal sphincter. The long-term follow-up in infants showing failure of the medical treatment, bronchial asthma appeared in 56.6%.
