[Low bone mass in a 17-year-old girl in the course of yolk sac tumor treatment--case report].

The aim of the paper was to present symptoms and results of biochemical and densitometric examination in a 17-year-old girl. The girl had yolk sac tumor at the age of 12, in course of which she developed secondary osteoporosis.

[Comparison of body fat measurement methods in children].

Introduction: In the last decades the prevalence of overweight and obesity in pediatric population has increased. The cardiovascular diseases and type 2 diabetes are the consequences of fat tissue disturbances, so measurements of body fat in children might be expedient. Aim of the study was to compare the results of percent body fat measured on bioelectric impedance (BIA) and anthropometric method with reference method--dual-energy X-ray absorptiometry (DXA).

Extensively and partially hydrolysed preterm formulas in the prevention of allergic diseases in preterm infants: a randomized, double-blind trial.

Aim: A randomized, double-blind study was conducted to evaluate whether use of protein hydrolysate-based preterm formulas in infants with an atopic predisposition helps prevent the development of allergic diseases.

Methods: Preterm infants (n = 122) with at least one first-degree relative (parent or sibling) with allergic disease were randomly assigned to receive an extensively or partially hydrolysed preterm formula (intervention groups) or a standard preterm formula until 4 to 5 mo of age. Infants whose parents preferred that they be breastfed received their mothers' fortified breast milk.

Extensive and partial protein hydrolysate preterm formulas: the effect on growth rate, protein metabolism indices, and plasma amino acid concentrations.

Background: The use of protein hydrolysate preterm formulas is restricted because data on their nutritional adequacy are scarce. The authors evaluated the rate of growth and indices of protein metabolism in low-birth weight infants fed extensive and partial protein hydrolysate preterm formula followed for 12 weeks.

Methods: A total of 61 low-birth weight infants were assigned randomly to receive extensive protein hydrolysate preterm formula (EH: n = 16), partial protein hydrolysate preterm formula (PH: n = 15), and standard preterm formula (SF; n = 15), or were fed their own mother's fortified breast milk (FBM; n = 15).

Clinical and immunological condition of newborns of mothers treated for recurrent spontaneous abortions with paternal lymphocytes immunization.

Objective: The aim of this study was to evaluate the clinical condition at birth and some laboratory parameters in newborns of mothers treated for recurrent spontaneous abortion (RSA) of unknown etiology with paternal lymphocytes immunization.

Study Design: The study comprised 104 newborns delivered by 102 women with RSA, who underwent alloimmunization and 90 randomly chosen control newborns. The following parameters were analysed in two groups of newborns: general condition at birth, physical development, course of adaptation period, values of hematological and immunological (percentage of CD3, CD4, CD8, CD19 and CD3/CD25 lymphocytes, chemiluminescence of neutrophils at rest and stimulated with opsonized zymosane) parameters in umbilical arterial blood.
