[The intelligence quotient and malnutrition. Iron deficiency and the lead concentration as confusing variables].

This study gave us the opportunity to know the roles iron deficiency and the presence of lead in blood play, as confounding variables, in relation to the state of malnutrition and the intellect of those children. A sample of 169 school children were classified according to their state of nutrition, their condition in reference to serum iron and lead concentrations. In addition, their intelligence was evaluated. The results confirmed that those children with lower weights and heights registered lesser points of intelligence; in fact, iron deficiency cancels out the difference in favor of those taller and weighing more. Lead did not contribute as a confounding variable, but more than half of the children showed possible toxic levels of this metal.

[Behavioral development and nerve conduction velocity during recovery from malnutrition].

OBJECTIVES: To research if the improvement in psychomotor development observed during the treatment of malnutrition, is related to favorable changes in the speed of nerve conduction and in the excretion of hydroxy-indole acetic acid (indole). DESIGNED OF THE STUDY: Prospective, of a descriptive type, includes the follow-up of children during the first month of treatment. APPLICATION: To better know the impact which malnutrition has on mental development. PATIENTS: Nine children, ranging from three to 15 months of age, gravely undernourished. INTERVENTION: The neurological development, the speed of nerve conduction and the excretion of indole were evaluated at 10 day intervals. MEASUREMENTS AND RESULTS: Using the Gesell technique in order to evaluate the development, the measurement of conduction through the medial and external popliteal sciatic nerves and indole excreted in 24 hours, a quantitative increase of all of these variables was seen in 24 hours. At the beginning the conduction speed was slow (less than 30 m/s) and the excretion of indole was very low (0.28 mg/24 h). After the tenth day these measurements returned to normal, although the development coefficient was found to still below at the end of the study (63.9 +/- 21.0). CONCLUSIONS: Simultaneous to the neurological deficit, there is a reduced speed of conduction, which returns to normal after the tenth day without a positive correlation with motor functions and development. Neither does the disponibility of serotonin (judged by the excretion of indole) correlate with the speed of conduction.

[Vitamin E concentration in children with proteino-energetic malnutrition].

Fourty eight malnourished infants were studied in regard to plasma vitamin E levels. The mean plasma vitamin E concentration was 0.41 mg/dL (+/- 0.20); the values ranged from less than 0.10 to 0.96. Only 4 children had an acceptable level of this vitamin (greater than 0.70 mg/dL). The possible interrelationship of vitamin E and red cell fragments in blood was investigated in 24 of the children. The data obtained do not suggest that a low plasmatic vitamin E level is not related to either, red cell fragmented or hemoglobin level.

[Reasoning strategies in biomedical research].

Some modalities of thinking, in order to arise logical presumptions and steady conclusions in research, are presented. The paper aims to provide concepts with which the hypothesis are established, and the way to make inferences in research.

[Iron deficiency in children: metabolic and pathogenic aspects. I].

Iron deficiency is the most commonly recognized form of nutritional deficiency in the world. In recent years, iron metabolism have became better defined and the physiopathology and pathogenesis of the disease have been better understood. In this report is reviewed some of this information.

[Solute charge in milk feeding of babies with diarrhea].

In each one of the samples, investigation of osmolarity, concentration of sodium chloride and proteins and bacteria was carried out. With these data, concentration of solutes in milks was estimated, together with a calculation of renal charge they represented. The most outstanding results showed that mothers offer whole and half skimmed milks at concentrations less than normal dilutions; thus, the solute charge was found in most cases, far below figures reported as average. In a good number of milks, osmolarity showed to very high, specially in those added with corn syrup. Only in 9 of the formulas germs were not identified; in the rest, E. coli predominated and there was high index of contamination.

[Congenital pyloric hyperthrophy. Factors associated with its frequency].

With the idea of clearing out several variables individually found associated with a greater incidence of congenital pyloric stenosis in the same group of children, 298 clinical histories in infants complaining of this deviation were reviewed. Information was obtained as to sex, birth number, blood group and the month these children with stenosis were born. The distribution of frequencies in each one of these variables was compared to that in 309 children surgically operated from peritonitis. The results showed a greater incidence of congenital pyloric stenosis in males than in females; also, the disease appeared more frequently in first-borns. Patients with type A blood group were less prone to present the anomaly. The birth month showed no statistical difference. The findings stress the importance shown by the genetic component of this disease.

[Height of children with G. lamblia and there capacity to absorb d-xylose].

The investigation was carried out with the purpose of studying the capacity to absorb d-xylose in children with G. lamblia establishing also, whether or not their height was reduced. The study is included 25 school age children with giardiasis, pairing them according to sex and age with another 25 without intestinal parasitosis.

[Basic diet in the treatment of infants with prolonged diarrhea].

Fourteen infants between 1 and 9 months of age received elemental diet by continuous nasogastric drip. All had diarrhea (average duration 32 days). All were malnourished. Eight had carbohydrate intolerance. Two had intestinal pneumatosis. Elemental diet was used at first in 12.5% concentration and increased progressively until it reached a 25% concentration. Clinical response was favorably in every case.

[Megaloblastic anemia in the recovery of the malnourished child].

With the purpose of analyzing the evolution in weight before and after treatment of megaloblastic anemia with folic acid, we studied the clinical changes and the evolution in weight in 8 malnourished children who developed this type of anemia during their recovery. Seven out of the 8 cases were less than 20 months of age; 5 of them came from mothers who had had five or more pregnancies; in 7 a history of diarrhea of prolonged course was presented and 2 cases had been given sodium diphenylhydantoin. Increase in weight before treatment of anemia with folic acid was lesser than the one for the days following treatment in seven of the patients. Simultaneously, an important change in behavior was appreciated, without being possible to atribute this change or the increase in weight to a quantitative change favorable to the ingestion of proteins and calories.
