Brain tumors are a common cause of epilepsy. Tumor type and location are determining factors that significantly influence seizure frequency. The aim of this study was to analyze clinical data of patients diagnosed with brain tumors and epilepsy. Data for this study were obtained from patient medical records over a 6-year period (2000-2005). Patient history and findings obtained by diagnostic methods such as electroencephalography, computerized tomography and magnetic resonance were analyzed. Data were analyzed by appropriate statistical methods and the structure, prevalence, mean and standard deviation were calculated. The significance of results was tested by use of t-test and chi2-test. A total of 15 933 patient charts were analyzed. Out of 15 933 patients, 10.8% were diagnosed with epilepsy and 175 (1.09%) patients had brain tumor, 75 (42.86%) of which were significantly associated with epilepsy (P > 0.05). Almost forty-three percent (42.86%) of tumors were epileptogenic, with no significant sex difference (confidence level of 95%). Fifty-seven (32.5%) brain tumor patients were aged 51-60. The mean age of all patients with brain tumors was 41.6 years. Focal sensorimotor seizures were dominant in 40 (53.3%) cases. Among epilepsy cases with known etiology, 75 (6.8%) patients had epileptogenic tumors. Types of seizures in patients with epilepsy were different from seizures provoked by brain tumors. The most common tumor site was temporal region (43.4%). There was no significant difference according to epileptogenesis. Focal sensorimotor seizures were common in patients with frontal and parietal region tumors.

INTRODUCTION This study investigates association between psychosomatic and traumatic symptoms among adolescents. SUBJECTS AND METHODS This cross-sectional survey using self-completion questionnaires was conducted among 868 adolescent in grade 6th, 7th and 8th of primary schools in Mostar (Bosnia and Herzegovina). RESULTS Psychosomatic symptoms are strongly associated with traumatic symptoms, with exception of symptom of anger. The association is the highest between anxiety, depression and PTS symptoms on the one side and cardiovascular symptoms on the other side. CONCLUSION According to our results, psychosomatic symptoms are strongly associated with psychosomatic symptoms in early adolescence.

By means of ab initio calculations and spin-polarized scanning tunneling microscopy experiments the creation of a complex energy dependent magnetic structure with a tailored spin-polarized interface is demonstrated. We show this novel effect by adsorbing organic molecules containing π(p(z)) electrons onto a magnetic surface. The hybridization of the out-of-plane p(z) atomic-type orbitals with the d states of the metal leads to the inversion of the spin polarization at the organic site due to a p(z)-d Zener exchange-type mechanism. As a key result, we demonstrate the possibility to selectively and efficiently inject spin-up and spin-down electrons from a ferromagnetic-organic interface, an effect which can be exploited in future spintronic devices.

We investigate the spin- and energy-dependent tunneling through a single organic molecule (CoPc) adsorbed on a ferromagnetic Fe thin film, spatially resolved by low-temperature spin-polarized scanning tunneling microscopy. Interestingly, the metal ion as well as the organic ligand show a significant spin dependence of tunneling current flow. State-of-the-art ab initio calculations including also van der Waals interactions reveal a strong hybridization of molecular orbitals and substrate 3d states. The molecule is anionic due to a transfer of one electron, resulting in a nonmagnetic (S=0) state. Nevertheless, tunneling through the molecule exhibits a pronounced spin dependence due to spin-split molecule-surface hybrid states.
