Introduction: Elderly persons have higher risk for falls, compared to younger population. Although no single risk factor causes all falls, a great deal of risk factors to which an individual is exposed, i.e. osteoporosis, lack of physical activity, impaired vision, usage of drugs, living settings etc, can be treated. Objective: To investigate the risk for falls in elderly patients treated in Family medicine teaching center (ECPM), Primary Health Care Center Banja Luka. Method: This prospective study was conducted in June 2012. The study included 150 patients aged 65 years and older. Patients were chosen randomly. In study were included patients who have visited their family doctors on every of Mondays in June 2012. The Tinetti Gait and Balance Instrument was used to asses the risk for falls. Patients were examined to asses gait and balance according to Tinetti questionnaire, and supplementary questionnaire was created to record data about age, sex, chronic diseases and drugs that patients take. Results: The study included 91 (60.7%) female and 59 (39.3%) male patients. The average age of patients was 74.71 years. 77 (51.3%) were aged 65 to 75 years and 73 (48.7%) were more than 75 years old. Results of Tinetti Gait and Balance Instrument showed that the risk for falls was high in 55 (36.7%), moderate in 31 (20.7%) and low in 64 (42.7%) patients. Conclusion: Approximately, one third of investigated patients had high risk for falls, what indicates that family doctors should be more involved in fall prevention in elderly and in constant educating of older adults and their families.

In this article, we briefly summarize our results gained from recent density functional theory simulations aimed to investigate the interaction between organic materials containing π-electrons (i. e., several benzene-like molecules and graphene) with ferromagnetic surfaces. We show how the strong hybridization between the pz-electrons that initially form the π molecular orbitals with the magnetic d-states of the metal influences the spin polarization, the magnetic exchange coupling, and the magnetization direction at hybrid organic-ferromagnetic interface. From a practical perspective, these properties play a very important role for device applications based on organic materials and magnetic surfaces.

Obturator hernia rarely occurs; it represents less than 2% of all abdominal hernias. It is a protrusion of the preperitoneal fat tissue or peritoneal defect through the obturator channel. Rule is that it is a disease of skinny, older women (seventh or eighth decades), usually multiparous, predominantly right-sided, usually incarcerated, rarely diagnosed preoperatively. The clinical diagnosis is rarely set due to the unclear signs and symptoms. Because of the delayed diagnosis the postoperative morbidity and mortality is significantly increased. CT of the pelvis is almost 100% accurate in the diagnosis of the obturator hernias and should be the modality of choice in elderly patients with the bowel obstruction of an unknown etiology. We report a case of a 70 -yearold woman who had been admitted to our department on several occasions due to the suboclusive problems and the obturator hernia with a Meckel’s diverticulum was verified intraoperatively.
