[Qualitative malnutrition due to incorrect complementary feeding in Bush Negro children in Suriname].

OBJECTIVE: To determine whether the increase in the percentage of stunted growth in Bush Negro infants in the interior of Surinam is related to an absolute food (i.e. energy) shortage or to a shortage of protein. DESIGN: Descriptive. METHOD: In the villages of Dan and Botopasi, children aged 2-5 years from two schools and their mothers were examined. Growth during the first year of life, duration of breastfeeding, age of introduction of and composition of complementary feeding and current nutritional status of mother and child were determined. RESULTS: Sixteen children and their mothers were included. Compared to the Dutch growth charts, birth weight was significantly lower (p = 0.03). After the age of 6 months there was a significant dropping off in weight gain (p = 0.018). Five of the 16 children received protein-poor complementary feeding, which did not lead to catch-up growth. Between the ages of 2-5, 6 of the 16 children showed stunted growth but none of the children or their mothers was wasted. Five of the 16 mothers had a body mass index > 25. CONCLUSION: The nutritional status of the mothers showed that there was no absolute shortage of energy. The protein content coming from the complementary food for the Bush Negroes in our research group was below recommended levels. Stunted growth in these children is better explained by a shortage of well-balanced complementary feeding rather than by an absolute shortage of energy. Education about food recommendations for the young child is of great importance in the prevention of chronic malnutrition.

Heminasal aplasia: a case report and review of the literature of the last 25 years.

We report a child with right-sided heminasal aplasia in combination with anomalies of the right eye and maxilla. Unilateral aplasia of the nose is a rare congenital malformation. It is often associated with other malformations of the facial region, including abnormalities of the eye and lacrimal system, proboscis lateralis, and facial bone malformations. The eye anomalies in our patient consisted of microphthalmia with blepharophimosis and coloboma of the iris, retina and upper eyelid. Also hypoplasia of the lacrimal apparatus and right maxilla, and a rudimentary alveolar cleft on the same side were present. The embryological development of the midface can explain this association of anomalies.

Apple juice malabsorption: fructose or sorbitol?

Carbohydrate malabsorption after apple juice ingestion may produce abdominal symptoms and diarrhea, especially in children. The carbohydrates suggested to play roles in this process are fructose, as it is present in excess of glucose, and sorbitol. Absorption of the carbohydrates in apple juice was investigated in 17 children and 12 adults by means of the hydrogen breath test. Apple juice was given at a dose of 15 ml/kg body weight, with a maximum of 375 ml. Fructose (0.6 g/kg) and sorbitol (0.06 g/kg), alone and in combination, were administered in amounts similar to their contents in apple juice (fructose as excess over glucose content). Apple juice malabsorption, as judged by a peak breath H2 excretion of > or = 20 ppm, was found in 11 children (65%) and 4 adults (33%). Of those malabsorbing apple juice, 7 of 11 children malabsorbed fructose, 1 of 11 sorbitol, and 4 of 11 the combination; the four adults absorbed all test solutions completely. We could not find an additive effect of sorbitol on breath H2 excretion after fructose ingestion. Peak breath H2 concentrations after apple juice ingestion (mean +/- SEM: 43 +/- 7 ppm) were higher than those with fructose (23 +/- 5 ppm; p < 0.05) or the fructose-sorbitol combination (20 +/- 5 ppm; p < 0.05). Fructose, and not sorbitol, is the sugar responsible for the increase in breath H2 after apple juice consumption and therefore for the diarrhea accompanying excessive apple juice consumption in toddlers.

Fructose breath hydrogen tests.

Fructose absorption was studied by the breath hydrogen test in 114 healthy children aged 0.1-6 years, given either 2 g/kg or 1 g/kg of fructose. All 57 children given 2 g/kg had peak breath hydrogen excretions > or = 20 ppm. At 1 g/kg only 25/57 (44%) showed incomplete absorption and the percentage incompletely absorbing fructose and the peak breath hydrogen value were significantly higher in children aged 1-3 years. Interestingly, this age distribution correlates with that of toddler diarrhoea.

[Intraosseous infusions in children].

Tibial intraosseous infusions can be invaluable in the management of the pediatric patient who is in cardiac arrest or severe shock when vascular access by the intravenous route is unattainable. Recently there has been renewed interest in this procedure. There is a small risk of complications.
