Breast vs. bottle: differences in the growth of Croatian infants.

The aim of the paper was to compare the growth of rural Croatian infants with 2000 Centers for Disease Control and Prevention (CDC) growth standards and to evaluate the potential preventive influence of breastfeeding on the development of obesity in infancy. Two hundred three infant-mother pairs from Baranja, an Eastern region of Croatia, were enrolled into this study. Retrospective evaluation of infants' medical charts was used to obtain anthropometric data recorded at the birth, 1, 3, 6, 9 and 12 months of age. Infant feeding mode was self-reported by mothers. Breastfed infants gained the least weight of all observed groups. Up to 6 months of age, formula fed infants had the highest weight gain and after 6 months of age, mixed milk fed infants had the highest weight gain. At 12 months of age, 6.4% of all study infants and 7.6% of mixed milk fed infants were at risk of overweight, while the same risk for the group of breastfed infants was 4%. Most of the study infants achieved higher values of body mass and length than the child growth standards. Exclusively breastfed infants, in comparison with other study groups (formula fed infants, mixed milk fed infants and cow's milk fed infants), had lower weight-for-length z-scores during the first year, which suggests that breastfeeding may have a preventive impact on obesity development.

Exclusive breastfeeding and growth in Croatian infants--comparison to the WHO child growth standards and to the NCHS growth references.

The objective of this study was to compare the growth of exclusively breastfed infants and formula fed infants in eastern Croatia. Additionally, we compared growth patterns and estimated overweight based on the World Health Organization (WHO) child growth standards and the National Center for Health Statistics (NCHS) references. The growth of 88 Croatian infants in two feeding groups (44 breastfed and 44 formula fed) has been researched and presented. The feeding mode was obtained by the 24-hour dietary recall method. Anthropometric measurements were performed at birth and at 1, 2, 3, 4, 6, 9 and 12 months of age. There were significantly lower increases in weight and length in exclusively breastfed infants versus formula fed at 12th month (p < 0.05). The weight gain of exclusively breastfed infants was 665 +/- 886g, and among formula fed infants 72 +/- 71254g, and also the exclusively breastfed infants showed significantly lower length gain (25. +/- 3.1 cm) than formula fed infants (27. +/- 3.1 cm) in the period from birth to the end of the first year. Differences shown in assessment of growth, depended of growth chart used WHO child growth standards or NCHS references. A larger number of overweight children were found in the formula fed group in comparison to both references, suggesting that exclusive breastfeeding prevents this occurrence. We conclude that breastfeeding provided the nutrients necessary for infants to keep with the WHO standards of regular growth in children.

Low levels of immunoglobulin A in children with intrinsic asthma: a possible protection against atopy.

Immunoglobulin A and G (IgA, IgG) serum concentrations were detected in children with nonallergic/intrinsic (36 children) or allergic/extrinsic asthma (43 children) and in age-matching control children (40 children). Asthmatic children with allergic asthma had lower IgA (1.36+/-0.54 g/L) and higher IgG (10.48+/-2.77 g/L) levels than the age-matching control children group (1.63+/-0.69 vs. 9.01+/-2.32 g/L). Children with nonallergic/intrinsic asthma had lower IgA (1.03+/-0.41 g/L) ( p = 0.004) and IgG (8.38+/-1.93 g/L) (p = 0.001) levels than the allergic/extrinsic asthma group (1.36+/-0.54 vs. 10.48+/-2.77 g/L). Low IgA levels were found in children with nonallergic/intrinsic asthma and high IgG levels were found in those children with allergic/extrinsic childhood asthma. The hypothesis is that the increased incidence of asthma in the population may be caused by a decrease in childhood infections (hygiene hypothesis). Frequent infections in early life boost the immune system, stimulating Th1-type response in young children and reducing the risk of atopic diseases. Our hypothesis is that low IgA (and/or IgG) levels in our patients might be responsible for infection development among those children with nonallergic/intrinsic asthma. These infections stimulate the normal development of immune system in young children, reducing risk of atopy, so that those children do not get allergic/extrinsic childhood asthma. Intrinsic childhood asthma=nonallergic (nonatopic) childhood asthma. Extrinsic childhood asthma=allergic (atopic) childhood asthma.

Diagnostic value of a peroral sucrose permeability test in children with recurrent upper abdominal pain.

The access of ingested sucrose into blood and urine indicates the presence of mucosal lesions in the upper gastrointestinal tract. The study involved 42 children, aged 5-15, having recurrent upper abdominal pain and 43 peers with minor extra-abdominal complaints. Sucrose in urine was determined by thin layer chromatography. The test was positive in 27 out of 42 children having recurrent abdominal pain (64.3%) and in none of the control children (chi2 = 37.6, p < 0.0001). When correlated with endoscopic findings it was falsely negative in 12 out of 38 patients with endoscopically verified lesions of the stomach or duodenum and falsely positive in 1 out of 4 without lesions. Sensitivity of the test was 68.4%, specificity 97.9%, positive predictive value 96.3%. The test cannot be used as an alternative to endoscopy, but may serve for screening of candidates for it.

Chronic tension-type headache in school-aged children--personality traits and behavior.

Basic personality traits and specific behavior characteristics were assess in 39 patients (12 to 15 years old) having chronic tension-type headache. Patients were referred for clinical examination to the Neural-pediatrics Ward of the Department of Pediatrics, Osijek, Croatia. Eysenck Personality Questionnaire--Juniors (EPQ-J), a new Croatian personality Questionnaire of domination, aggression, introversion and ambition (DAIA), were applied for the testing. The scores obtained by patients in personality questionnaires were compared with averages scores normal sample of healthy pupil same ages. Our patients were found to have no signs of emotional instability. Their behavior is prosocial, nonaggressive, and ambitious, aimed at the achievement of superior results at school and life although already quite successful in their studies. Tensions arising from the school setting seem to be important factors triggering tension-type headaches.
