[Barrett's esophagus: diagnosis and coexistent diseases in childhood].

From 1990 to 1998, 12 patients with columnar metaplasia of the lower esophagus were diagnosed. Only 4 of them displayed a Barrett's epithelium (BE) with a specialized columnar epithelium and globet cells. As it is already published, a male predominance was observed.

[Correlation of IgA class antigliadin and antiendomysial antibodies (IgA-AGA-IgA-EMA) with intestinal histology in celiac disease].

The aim of this work was to establish the diagnostic and follow up value of IgA-class antiendomysium (IgA-EmA) and IgA-class antigliadin (IgA-AGA) antibodies in celiac disease. Correlation with the intestinal histology at the different stages of the disease was evaluated, as well as its therapeutic monitoring ability. Fifty six children, twenty seven girls and twenty nine boys, aged six months to twelve years old, were studied.

[Chronic idiopathic intestinal pseudo-obstruction: visceral myopathy. Report of 4 cases].

Chronic intestinal pseudo-obstruction is the term applied to a heterogeneous group of functional motility disorders sharing a common clinical expression: signs and symptoms of bowel obstruction in absence of mechanical occlusion. It is caused by ineffective intestinal propulsion. The chronic form of intestinal pseudo-obstruction may be primary or secondary.

[The correlation of IgA-class antigliadin and antiendomysial antibodies (AGA-IgA--EmA-IgA) with the intestinal histology in celiac disease (CD)].

The aim of this work was to establish the diagnostic and follow up value of IgA-class antiendomysium (IgA-EmA) and IgA-class antigliadin (IgA-AGA) antibodies in celiac disease. Correlation with the intestinal histology at the different stages of the disease was evaluated, as well as its therapeutic monitoring ability. Fifty six children, twenty seven girls and twenty nine boys, aged six months to twelve years old, were studied.

[Ulcerative colitis in children. Levels of salicylazosulfapyridine and sulfapyridine during treatment].

Salicylazosulfapyridine (SASP) is a drug used in the treatment of ulcerative colitis (UC) owing to the therapeutic action of the 5-aminosalicylic acid produced by the splitting of the molecule in the cecum, which also yields the absorbable compound Sulphapyridine (SP). The aim of our work was to assess the levels of the drug in blood (SASP and SP), to correlate them with undesirable effects in any, to verify their fluctuations in the dosing interval and to investigate the extent of the excretion of the drug in the children who were studied. 10 children (6 to 16 years) with UC, who were treated with SASP (dOsage schedule 0.

[Fecal alpha 1-antitrypsin clearance in protein-losing enteropathies in pediatrics].

Fecal alpha-1-antitrypsin clearance (A-1-At Cl) was performed on 47 pediatric age patients with various digestive diseases: 6 with ulcerative colitis, 5 with celiac disease, 6 with cow milk protein intolerance, 1 with intestinal lymphangiectasia, 1 with non specific diarrhea and the control group was composed of 10 children without digestive disease. The group of patients with digestive disease showed values of fecal A-1-At Cl significantly higher than the control and non specific diarrhea groups (p less than 0.05).

[Determination of amylase creatinine clearance in children and adolescents].

Unlabelled: 24 children whose ages ranged from 10 days to 14 years (x 5.5. ys.

[Fibrocystic disease of the pancreas: a presentation feature. Anatomopathological report].

Five patients with CF (cystic fibrosis) dead between 1974 to 1982 at ages ranging from one to six months are presented. All of them showed edema, hypoalbuminemia and anemia in a severely compromised clinical situation, and failure to gain weight in spite of being breast-fed in the first weeks of life, in four of them. All of them were second or third degree malnourished babies (Gomez classification) at admission.

[Juvenile polyps in childhood].

61 children, from 12 months to 14 years old with colonic juvenile polyps were studied using double contrast radiology and conventional and fiber optic endoscopy. In all cases the tumor excision was performed without fulguration. 43 polyps were located within the rectal area and 17 in the colon.

[Rectal tonometry in the differential diagnosis of constipation in pediatrics].

Based on the difficulties regarding the clinical, radiological, and histological diagnosis of colonic aganglionosis, we resorted the motility studies. Sixty-two children (15 days-10 years of age) were studied by means of rectal motility without knowing the results of the other auxilary methods. We obtained a clear difference between aganglionic and other group formed by constipated functional or psicogenic.

[Gastric polypoid heterotopy in the small intestine].

We present a 14 year old girl with a two years' history of colicky abdominal pain associated with the palpation of a tumor in the left upper quadrant of the abdomen. During these two years, the pain and the tumor appeared and disappeared spontaneously several times. In the operation we found a jejunojejunal intussusception, the head being a sessile polyp placed 20 cm from the ligament of Treitz.

[Radiologic diagnosis of Meckel's diverticulum].

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.
