RESUMO
The aim of our study was to determine whether the immunohistochemical expression of placental vitamin D receptors is altered in pregnancies complicated by preeclampsia. Vitamin D receptor expression was immunohistochemically analysed in the placentas of three groups: a control group, and early- and late-onset preeclampsia groups. Total immunohistochemical intensity staining of placentas showed that the control group had a median vitamin D receptor (VDR) expression significantly higher than the placentas of mothers with early- and late-onset preeclampsia. There was no difference among the three groups in a semiquantitative analysis of VDR staining of the stroma only. Vitamin D receptors showed lower median expression in preeclampsia-affected pregnancies, especially early-onset preeclampsia. Therefore, Vitamin D receptor expression may be an important marker for normal placentation and preeclampsia onset.

Our aim was to investigate the incidence of respiratory infections in children treated at the Pediatric Department of the University Hospital Mostar during war (1993 and 1994) and after the war (2003 and 2004). In order to collect data we used medical histories of children with respiratory infections. Incidence of respiratory infections in children in war period was 230/1000, while in post-war period it was 190/1000. There was no significant difference in the incidence of respiratory infections in children during war and after the war (p = 0.051). We have not found increase in respiratory infections prevalence in children treated during war period at the Pediatric department of University Hospital Mostar, compared to the period after the war. However, we did report certain differences related to age, clinical parameters, seasonal pattern, diagnosis, therapy and mean hospitalization time.
