A review of the literature revealed 8 cases of this association and, analyzing together the series of findings of cancer in chagasic organomegalies, we found a frequency of 4.8% in megaesophagus and 0.1% ...
متن کاملChagasic megaesophagus and megacolon diagnosed in childhood and probably caused by vertical transmission.
Reports on children presenting symptoms compatible with the chronic phase of Chagas disease are sporadic.

The etiology was established by means of laboratory and histological features. Based on epidemiological data, the authors concluded that vertical transmission was the...
متن کاملLower oesophageal sphincter response to pentagastrin in chagasic patients with megaoesophagus and megacolon.
Intraluminal manometric studies were performed in 14 chagasic patients with megaoesophagus, 10 chagasic patients with megacolon, and 15 control subjects. Basal lower oesophageal sphincter pressure was 20.27+/-1.16 mmHg (mean+/-SEM) in controls as compared wtih 15.16+/-1.53 mmHg in chagasics with megaoesophagus and 14.38+/-1.50 mmHg in chagasics with megacolon. Dose-response studies to intraveno...
