This paper describes our experience with pre-surgical diagnosis of Meckel's diverticulum. We used a naso-jejunal-ileal tube, through which, we injected small amounts of radio-opaque fluid and air, thus utilizing double contrast. In seven children diverticulum was shown to be present by radioscopic and radiographic techniques; this was later confirmed during laparotomy. X-ray findings were compared with Tc99 scanning results.
The aerobic flora of 2 groups of children (normal and with malnutrition) with acute diarrhoea was studied, by intubation of the upper and middle small intestine and by stool culture. All the 27 children studied presented bacterial concentrations of 10(5) germs/ml at one or both levels studied. In 9 cases enteropathogen bacteria e were isolated from stools, and in 6 of these they were also found in the small intestine. The results show the elevated incidence of overgrowth of the small intestinal aerobic flora in children with acute diarrhoea. This fact is mentioned as another etiological factor to be taken into consideration in this pathology.
Circulating antibodies to cow's milk protein were investigated in 35 normally nourished infants aged 2 to 11 months. Nine were healthy (control group), and the remaining 26 were convalescents from acute diarrhoea. At the time of assay they were normally hidrated and being fed diluted cow's milk. The results showed elevated hemagglutinating antibody titers in the group of children with diarrhoea, statistically different to the control (p less than 0.001). The existence of an enhanced absorption of non degraded milk protein during the disease is assumed. This observation constitutes one more element in favour of the risk of exposing the digestive tract to antigenic loads in pathological situations as those considered.
