Esophageal reflux--an unrecognized cause of recurrent obstructive bronchitis in children.

Forty-three children with recurrent obstructive bronchitis but without prominent gastrointestinal symptoms were studied for esophageal reflux roentgenographically and by manometry. Roentgenographic evidence for reflux was shown in 26; these patients had a mean lower esophageal sphincter pressure of 6.3 mm Hg as compared to a mean LES pressure of 21.9 mm Hg in normal control infants. The remaining 17 patients had a mean LES pressure of 10.0 mm Hg, also significantly lower than that of control subjects. Fifteen of 20 patients with recurrent obstructive bronchitis noted alleviation of their pulmonary symptoms after medical treatment of their reflux. Sequential studies of another group with radiologically demonstrated reflux showed increases in sphincter pressures and disappearance of radiologically observed reflux in one third of the patients. It is suggested that esophageal reflux should be sought in patients with recurrent bronchitis: if found, antireflux therapy might be expected to improve the pulmonary symptomatology.

[Radiological and manometric study of gastroesophageal reflux in normal infants].

The incidence of the gastroesophageal reflux was studied in 39 healthy infants with ages between 2 and 24 months. X-ray studies of gastroesophageal passage and esophageal manometry were practiced in all cases. Only 3 infants showed radiological reflux. The pressure in the gastroesophageal sphincter was normal in all babies and the highest pressures were reached less--than 6 months--old infants. Older infants showed lesser pressures. The same was true for the length of the gastroesophageal sphincter. The factors involved in the genesis of the gastroesophageal reflux are discussed.

[Evolutionary study of 81 children with celiac disease].

A review of 81 children with celiac disease over a period of 5 years is presented. These cases were seen at the Gastroenterological Unit of the Hospital de Nińos Roberto del Río, during years 1970 through 1972. 62% of the patients (50) were placed under control of their disease, the rest were studied and diagnosed only for other centers. The short term evolution was good in 48 children (96%), while the medium and long term evolution, 2 to 5 years, was good only in 56% of the patients. This evolution was in direct relationship to the fulfillment of the dietary indications. The therapeutic test was positive among the studied group. A delay was observed in 80% of the cases that lasted from 1 to 6 months. The clinical and laboratory features of the group are analyzed, and the working method is described.

[Recurrent obstructive bronchitis in infants].

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%.
