Weight-gain inhibition by lactose in Australian Aboriginal children. A controlled trial of normal and lactose hydrolysed milk.

Weight-gain in 35 slightly undernourished Australian Aboriginal infants was studied in hospital (49 admissions) during a blind controlled trial of a pre-hydrolysed low-lactose milk preparation and reconstituted full-cream milk powder. Infants fed the lactose hydrolysed milk gained 70% more weight than those receiving normal milk. Better weight-gains were achieved in those on the lactose hydrolysed milk irrespective of percentage standard weight for age, the presence of diarrhoea on admission to the trial, and stool sugar concentrations. The use of low-lactose milk should be considered in nutritional aid programmes for undernourished children throughout the world.

High frequency of lactose absorbers among adults with idiopathic senile and presenile cataract in a population with a high prevalence of primary adult lactose malabsorption.

22% of a group of adult Neapolitans were found to have persistent high lactase activity, and 16% were lactose absorbers as indicated by measurement of breath hydrogen concentration and rise in blood glucose after oral lactose administration. Among adults in the same area with idiopathic senile or presenile cataract 49% were identified as lactose absorbers with the breath hydrogen test and 55% by the rise in blood glucose. These results suggest that adults able to absorb galactose from a lactose-containing diet are especially susceptible to senile or presenile cataract.

Recurrent abdominal pain in children: a review of psychological factors and treatment.

This paper reviews current knowledge regarding recurrent abdominal pain (RAP) and the physiological, dietary, and psychological variables that may have some influence in pain episodes. Emphasis is placed on psychological factors and studies that have investigated psychological treatment modalities. There is some limited evidence of physiological dysfunction in RAP patients, and while some researchers have asserted that RAP may be a dietary disorder, results of several studies do not support this assertion. Studies examining psychological variables in RAP patients show elevated anxiety levels; however, elevated anxiety is also associated with organic abdominal pain. Psychological treatments focusing on cognitive-behavioral methods have demonstrated success in treating RAP. Follow-up studies are needed to determine the long-term success of these treatments, and continued research examining which children benefit from treatment would also be beneficial.

Methane and hydrogen exhalation in normal children and in lactose malabsorption.

UNLABELLED: Methane (CH4) and hydrogen (H2) are gases produced in the colon by the breakdown of carbohydrates, due to the action of anaerobic methanogenic bacteria. No papers have been published in pediatrics concerning these gases production and exhalation. Understanding of the pattern of H2, CH4, carbon dioxide (CO2), butyrates, indolellipsis,etc., production and exhalation, which may differ in gastrointestinal diseases, may be helpful as far as the diagnosis and treatment of some gastrointestinal conditions is concerned. Exhalation of H2, CH4 and CO2 by breath air was studied in basal conditions in 338 normal infants and in 27 lactose malabsorbers. Moreover, stools collected and stored for 10-12 h in anaerobic and aerobic conditions were incubated in anaerobiosis at 38 degrees C. After a 4-h incubation period, H2, CH4 and CO2 were determined. RESULTS: Methane production is independent of hydrogen production; the number of children producing CH4 increases from 0% at 12 months of age to 44% at the age of 9 years. In lactose malabsorption, we found 26 children producing increased quantities of H2 and no methane, and only one producing methane but no hydrogen, which proves that methanogenic bacteria are independent of H2-producing bacteria, and that CH4 determination is compulsory in the study of lactose malabsorption. The incubation of stools in an anaerobic milieu at 38 degrees C for 4 h, in an attempt to imitate the human colon, showed a great production of methane and less of H2 in the stools collected and stored in anaerobic conditions. The same incubation method was applied to the stools collected and stored in aerobic conditions: production of H2 and CH4 was much lower than in the collected and stored anaerobic group. The appearance of CH4 in the stools of the aerobic group proves that methanogenic bacteria are, to a small degree, resistant to oxygen. CONCLUSIONS: The study of gas exhalation in pediatrics merits more study by researchers, with a view to defining a special pattern of gas production in pathological conditions. The anaerobic stool incubation method is a good model for studying gas production under the effect of different diets and the gas production pattern in gastrointestinal diseases.
