[Influence of breast feeding on nutritional development of infants with persistent diarrhea].

The evolution of some nutritional anthropometric indicators was studied in a 115 breast-feeding infants (52 received breast-feeding during the first four months of life (120 days) exclusively and 63 mixed feeding). Breast feeding infants showed sustained weight increment during the four weeks of evolution. The multivariate repeated measures analysis performed, proved significant changes during evolution's time in all studied indicator in lineal form, as well as interaction between type of feeding and indicators evolution except the subescapular fat fold. Author concluded that it should be reinforced the breast-feeding practice promotion as an effective way for the nutritional recovery of breast-feeding infants with persistent diarrhoea.

[Clinical trial with a preparation based on propolis "propolisina" in human giardiasis].

The results of a clinic assay with an extract made out of propolis (bee glue) or "Propolisina" were showed with the aim of showing its effectivity against giardiasis. One hundred and thirty eight patients were studied 48 children and 90 adults, in 2 groups and they selected aleatorily to be treated with "Propolosina" or an imidazole derivate (tinidazole). The method for an exact diagnosis in children was duodenal aspiration and in adults duodenal mucosa frotis by means of duodenoscopy. Similar studies were carried out as a cure criterium in a 5-day term after being through with the treatment. Propolisina was used with different concentrations: in children (concentration at 10%) results showed a 52% cure. In 40 adults (concentration at 20%) it was obtained a similar result to that of tinidazole; and when propolisina concentration was elevated at 30% in the remaining 50 patients there was a higher effectivity (60 of cure Vs 40% with tinidazole). This work shows the success of this natural product, which is very easy to obtain in Cuba and with no side effects in the treatment of this intestinal parasitism, what is of great economical importance for our countries.

[A proposal for the classification of intestinal complications in giardiasis].

Two hundred children hospitalized in the National Institute of Gastroenterology were studied during the 1972-1980 period. The children, whose ages ranged between six months and ten years, presented chronic diarrhea in which Giardia lamblia was considered the causative agent. The diagnosis of parasitism was made with the detection of Giardia lamblia in the feces and/or duodenal content. A serum D-Xylose and jejunal biopsy were performed on all the patients and the histology of the mucosa was classified in keeping with the degree of atrophy according to Metayer and Laumonier. In our study we divided the patients into three groups: Group 1, parasitism due to Giardia lamblia in patients with a normal D-xylose and different degrees of atrophy of the jejunal mucosa, but with normal D-Xylose and Group 3, malabsorption due to Giardia lamblia, with a pathological D-Xylose and alterations in the intestinal mucosa. There were 35 cases in Group 1 (17.5%), 91 cases in Group 2 (45.5%) and 74 cases in Group 3 (37%). The predominant intestinal lesion was partial atrophy of the villi (143), 20 with subtotal atrophy of the villi and two with complete atrophy of the villi. It was shown that the host's response to infection by Giardia lamblia varies with differing effects on the structures and functioning of the jejunal mucosa. It is important to group patients with chronic diarrhea due to Giardia lamblia in this way since it allows for and individualized clinical approach and provides a prognosis in terms nutritional consequences resulting from possible persistence of the diarrhea and possible associated lactose intolerance.

Coeliac disease in Cuban children.

Coeliac disease is generally considered to be a disease of Europe, North America, and Australasia. A series of well-authenticated cases from Cuba is presented. One of the factors responsible for the presence of this disease in Cuba may be the increase in wheat consumption in the last few years. It is likely that coeliac disease exists in other tropical countries.

Duodenal intubation with secretin stimulus for diagnosis of giardiasis.

The use of secretin to facilitate the demonstration of Giardia lamblia in duodenal juice was studied in children under investigation for chronic diarrhoea. 30 children aged 3 months to 13 years, whose stools were negative for G. lamblia, were studied. G. lamblia was demonstrable in a sample of duodenal juice in 1 of the 30 children before an intravenous injection of secretin (1 or 2 mg/kg), but in 9 of the 30 children after secretin. It is concluded that examination of duodenal juice after secretin stimulus is an effective method of showing giardial infestation.

[Alagille's syndrome in Cuba. A report of 9 cases].

Alagille's syndrome or arteriohepatic dysplasia has been described in Cuba in nine patients between nine months and 12 years of age (8 males and one female). Among the clinical features we found five major abnormalities: chronic cholestasis with neonatal jaundice (9/9), peculiar facies (9/9), peripheral pulmonary artery hypoplasia associated with cardiac murmur (6/9), butter-fly-like arch defects (4/9), and posterior embryotoxon (6/7). Two children had a severe xanthomatosis. Laparoscopy showed green hepatomegaly depending on the degree of cholestasis, and only one patient had incipient signs of micronodular cirrhosis. Liver histology showed a paucity of interlobular bile ducts. Survival was of 60%. One patient survived more than 30 years. Four patients died of liver carcinoma (unique report in infants), broncho-pneumonia, acute renal failure, and sudden death respectively. Among the minor features were mental retardation (5/9), a peculiar voice (3/9), growth retardation observed in some of our patients. This is the first report on Alagille's syndrome in Latin America, because so far reports have come only from Europe and North America.

[Aflatoxin detection in urine in liver diseases in childhood].

During the last decade, a number of epidemiological and laboratory investigations have shown a close association among hepatitis B, dietary exposure to aflatoxin, and an increased incidence of hepatocellular carcinoma. An immunoenzymatic method for aflatoxin detection in urine was developed and assessed at the National Institute of Oncology. Fifty four children (age range 4-16 years) from the pediatric service at the National Institute of Gastroenterology were studied. Thirty patients had a diagnosis of chronic active hepatitis (CHA 17 of which 56%) were found aflatoxin- positive, 20 where HbsAg-positive carriers of which 7 of 35% were positive to aflatoxin, and 4 patients suffered from metabolic diseases from which 1 (25%) was found aflatoxin- positive. Controls and patients were matched by age, with 7.5% of aflatoxin-positive patients. Our results confirm the link between hepatitis B and aflatoxin in this type of patients compared to controls. The immunoenzymatic system proved to be specific for aflatoxin detection with a sensitivity of 100 picograms/milliliter.

[Treatment with Savary-Gilliard bougies in esophageal stenosis in children].

30 patients (less than 15 years old) were admitted for esophageal strictures, 16 of them secondary to corrosive injury. All the patients were treated with endoscopic dilatation with Savary-Gilliard bougie. The dilations were done with general anesthesia using an Olympus GIF-XP10 endoscope and with fluoroscopic control. In the esophageal stenosis secondary to caustic ingestion endoscopic injection with Betamethasone was also used. The most frequent site of the stenosis was the upper third of the esophagus, and the main type of stenosis was tubular in the secondary to caustic burns and annular in the other group. In the post-caustic group 385 dilations were performed in 115 sessions. In the other group 159 dilations were done in 51 sessions. Two perforations and one sepsis were reported in patients with corrosive stenosis. There was no mortality. 43.7% of the patients with corrosive stenosis and 85.7% with stenosis secondary to other causes obtained complete healing. Esophageal dilation with Savary-Gilliard bougies represents a safe and reliable method for the treatment of esophageal strictures.

[Risk factors for persistent diarrhea].

The current concepts in persistent diarrhoea (PD) are reviewed. 102 patients with acute diarrhoea and 85 with PD are studied. All were less than one year old. Information about age, nutritional status, time of breast feeding, previous episodes of acute and persistent diarrhoea and the previous use of drugs is registered. Microbiological and parasitologics studies were done to identify enteric pathogens. To prove the association of PD and the exposure to different risk factors the statistic method of Chi square (chi 2) was used and the odds ratio (OR) estimated. In order of importance and according to the OR the risk factors identified were: previous episodes of PD, malnutrition, less than one month with breast feeding, the use of metronidazol and antibiotics, multiple infections, previous episodes of acute diarrhoea and the identification of enteric pathogens. The most frequent pathogen was Salmonella followed by entero pathogenic Escherichia coli.

[Changes in the liver biopsies of pediatric cancer patients who carry the B virus].

Liver biopsies from 27 patients with malignant diseases and virus B carriers state were studied. The age of the patients ranged from 2 to 14 years. ELISA tests for virus B hepatitis were performed in all patients. Three of them resulted HBV positive at admission, whereas 24 became positive after anti-tumoral treatment onset. One patient was also virus C positive. Morphological disorders findings comprises: symptomless acute hepatitis in 7 patients (including the B-C carrier), minimal hepatocytes damage was found in 17 patients as the result of their carriers state and where also certain drug-induced hepatotoxic effect might be present. In this group there were also 7 biopsies with minimal portal region damage. Three biopsies were reported as normal liver tissue. This results confirmed the significance of the study of serological hepatitis viral test and hepatic biopsy in high risk group patients, where it is also necessary the vaccination against HBV before treatment onset.
