ABSTRACT

Background Several studies have reported that severe reflux esophagitis is rare in infants despite the well known high occurrence of regurgitation in early infancy. There is evidence of the importance of saliva for the pre-epithelial protection of the esophageal mucosa. Results A longitudinal study conducted on healthy infants indicated that the stimulated capacity of saliva secretion (saliva output per kg of body weight) was significantly higher during their first year of age compared to older children and adults. In addition, this secretion pattern was also observed in low weight newborns during the first weeks of life and persisted in infants with severe protein-calorie malnutrition (marasmus). Conclusion The greater ability to secrete saliva is an important physiological condition that may protect the infant from acid/pepsin aggression to the esophagus during early stages of development. .


Contexto Vários estudos têm indicado que a esofagite de refluxo é rara em lactentes no primeiro ano de vida a despeito da elevada ocorrência de regurgitação nesta fase da vida. Há evidências da importância da saliva para a proteção pré-epitelial da mucosa esofágica. Resultados Um estudo longitudinal conduzido em lactentes saudáveis indicou que a capacidade estimulada da secreção de saliva (volume de saliva/kg de peso) foi significativamente elevada no primeiro ano de vida comparada com crianças com mais idade e adultos jovens. Este padrão também foi observado nas primeiras semanas de vida de recém-nascidos com baixo peso e persistiu em lactentes com desnutrição proteico-calórica grave (marasmo) Conclusão A grande habilidade para secretar saliva é uma importante condição fisiológica que pode proteger o lactente da agressão ácido/péptica do esôfago durante os primeiros estágios do seu desenvolvimento. .

ABSTRACT

OBJECTIVE: To assess whether corpus gastritis due to Helicobacter pylori protects against erosive esophagitis in an area with high prevalence of H. pylori infection. METHODS: Biopsies obtained from gastric corpus and antrum in 151 patients with symptoms of gastroesophageal reflux disease were studied for presence of H. pylori and endoscopic evidence of gastritis. Presence and grade of esophagitis at endoscopy was recorded. RESULTS: Fifty-four (36%) patients had endoscopic esophagitis. Patients with severe esophagitis (>or= grade II) less often had active gastritis (15/45 vs. 55/98; p=0.02) and had a lower density of H. pylori (p=0.0003) than those without esophagitis. CONCLUSION: Active corpus gastritis due to H. pylori infection may protect against erosive esophagitis in patients with gastroesophageal reflux disease in the Middle East.

ABSTRACT

Se analizó la experiencia obtenida en el Servicio de Cirugía General del Hospital Docente "General Calixto García" en 90 valvuloplastias de Toupet realizadas consecutivamente. Las indicaciones para la operación fueron la hernia hiatal deslizante en 87 pacientes y la incompetencia del esfínter esofágico inferior en 3 pacientes. Se plantea que el tiempo de seguimiento posoperatorio osciló entre 1 y 9 años en los 80 operados que pudieron ser controlados tardíamente (88,9% de la casuística). Se informa que no hubo mortalidad imputable al procedimiento quirúrgico y que se obtuvo mejoría de los síntomas en el 95% de los pacientes; de los cuales, el 85% no presentaba ningún síntoma dependiente de la valvuloplastia realizada, ni de la enfermedad de base
