The aim of this study was to determine whether there is a correlation of latency and amplitude of P300 cognitive potential and the degree of lateralization of brain hemispheres. The study included 60 subjects whose age was between 45 and 56 years. Bioelectric brain activity was recorded using argentum chloride (AgCl) electrodes that were placed at central line of the scalp (over Fz and Cz regions) according to the international 10-20 standard. P300 was generated using “oddball” paradigm with randomized stimuli: A frequent 1000 Hz tone with an occurrence of 80 % and a 2000 Hz tone (target) with a 20 % occurrence. The measurement is done with the right hand (first recording) and left hand (second recording). All subjects in this study were tested for usage lateralization and showed that they are right-handed. Based on the results of gestural lateralization subjects are divided in three groups. In the group with high degree of lateralization latencies of P300 were significantly lower when dominant hand was used in comparison to non-dominant hand, on Fz electrode (t = 4,162, p<0,01) and Cz electrode (t = 5,302, p<0,01 (p<0.01) and amplitudes of P300 were significantly higher, on Fz electrode (t=-2,725, p<0,05), on Cz electrode (t=2,527, p<0,05). However, there were no statistically significant differences (p>0.05) for latencies and amplitudes of P300 between dominant and non-dominant hand for the group of subjects with weak and average degree of lateralization. In both subject groups, significantly faster RT was measured when dominant hand was used. The P300 cognitive potential and reaction time can contribute to the study of indicators of the functional hemispheric asymmetry of the brain.

It is known in the literature that the incidence and prevalence of suicide and attempted suicide in psychiatric patients is significantly higher than in the general population. The paper examined risk factors for suicidal behavior in the category of admitted patients hospitalized with the diagnosis of sleep disorders and affective (Unipolar resp. Bipolar depression). Study activated by 80 patients, 40 in both diagnostic groups received treatment at the Special Psychiatric Hospital in Gornja Toponica near Nis. The work methodology used are: psychiatric interview, Hamilton Depression Rating Scale (HAMD), and the C-SSRS (Columbia-Suicide Severity Rating Scale)- assessment tool that assesses suicidal ideation and behavior. The study results show that there is a relationship between suicidal behavior (suicide attempts and suicidal ideation) and the diagnosis of bipolar affective disorder, positive history of previous suicide attempts, so that these factors are stronger, to the degree of suicidality higher. On this sample, clearly suicidal behavior, with the same purpose, intensity of suicidal thoughts and medical impairment after suicide attempts were significantly more frequent in patients with Bipolar Affective Disorder in the depressive phase of the illness. Patients with a previous suicide attempt, and poor personal and social circumstances had a higher rate of attempted suicide.

Anatomy of the female pelvic viscera was investigated before and after the Tension free Vaginal tape (TVT-O). Forty patients were included in the study. Surgery was performed between 2009 and 2012 in Clinic of Urology (Clinical Center Nis) and Department of Urology (Municipal Hospital Prokuplje). Stress Urinary Incontinence (SUI) and anterior vaginal wall prolapse was confirmed in all patients. In all patients with anterior vaginal wall prolapse (grade≥2) both tension free vaginal tape (TVT-O) and anterior vaginal wall repair were performed. Pelvic Organ Prolapse Quantification (POPQ) system was used for the evaluation of prolapse before and after the surgery. Mean age of patients was 61 years. Spinal anesthesia was performed in thirty patients and general anesthesia in 10 patients. Intraoperative blood loss was under 50 ml. There were no bladder, nerve and blood vessels injuries . Thirty eight out of forty patients (95%) were satisfied with the outcome of the surgery. There was a significant correction of prolapse after the surgery. Recurrence of prolapse was found in patients with the high grade prolapse before the surgery, as well as, in patients with the history of previous anterior vaginal repair. Pelvic organ prolapse, congenital or acquired, is supported by the congenital weakness of the pelvic floor.

In care of minimal partial edentulism, ie the lack of a tooth, as an alternative method can be used inlay retained adhesive restorations. The aim of this paper is to present possibilities for the application ceramic systems used for adhesive prosthetic restorations. In the making inlay restorations in the region of the posterior teeth can be applied ceramic system of higher strength which can be veneered with translucent ceramics. With the development of adhesive dentistry, it is possible to establish a strong link between restoration and teeth by means of composite cements and thus ensure sustainability of recovery. The clinical procedure is simple, minimally invasive, and provides a glimpse into a way of making inlay retained fixed restorations.

The aim of the present study is to investigate the antioxidant properties of the lichen Cetraria aculeata. Antioxidant activity of the methanol and ethyl acetate extracts of lichen was tested by different methods including determination of total phenolics content, determination of total antioxidant capacity, DPPH free radical scavenging activity, inhibitory activity towards lipid peroxidation, ferrous ion chelating ability and hydroxyl radical scavenging activity. The extracts of the lichen C. aculeata showed significant antioxidant activity. The methanol extract showed higher values for total phenolics and total antioxidant capacity compared to the ethyl acetate extract, while the ethyl acetate extract demonstrated better results for DPPH radical scavenging, inhibitory activity towards lipid peroxidation, chelating ability and hydroxyl radical scavenging than the methanol extract. This is the first report of the antioxidant properties of Cetraria aculeata growing in Serbia. The results of antioxidant activity indicate the application of this lichen as source of natural antioxidants that could be used as a possible food supplement, in the pharmaceutical industry and in the treatment of various diseases.

Meniscus injuries occupy an important place among damages to the knee joint and are crucially important for athlets. Arthroscopy is a method of choice in both diagnostic as well as therapeutic treatment. After the intervention, it is necessary to start physical tretmeant as soon as possible. The study presents the treatment of 14 year old female patient, who started physical therapy five days after the removal of part of the lateral meniscus. Procedures involved electrical and kinesy therapy. Within the kinesy treatment static contractions were included, lymphatic drainage, and also passive exercises in order to increase range of motion. In the end, exercises against resistance were conducted to strengthen the musculature. After one month of therapy the treatment was completed, and patient was advised to continue strengthening the musculature at home. During the last examination the absence of swelling was noted, with painful sensitivity and limited motion in the knee. The MMT score for qvadriceps femoris was 4. The patient was advised to start with the lighter recreative activities. Arthroscopic meniscotomy is relatively rare intervention with adolescents, which was the motive for displaying this case. Applying early rehabilitation is fully exploited regenerative potential of this age and the optimal time for patients to return completely to usual activities.

Quality of life (QoL) is used in the natural and social sciences as a relatively new category which deserves more attention in research. Quality of life related to health is a term commonly used when QoL on health. An increasing number of research studies that are based on an examination of the QoL. This paper analyzes the concept of the QoL, the possibilities of measuring the QoL, a special emphasis is placed on measuring QoL in dermatovenereology. Given that the skin disease are of particular significance for the patient, the said indices are dermatologically quality of life, especially the quality of life of patients dermatological (DLQI).

Maligni tumori pljuvačnih žlezda su retka oboljenja i u najvećem broju se javljaju u velikim pljuvačnim žlezdama. Cilj istraživanja bio je da se analizira trend incidencije malignih tumora velikih pljuvačnih žlezda kod stanovništva grada Beograda. Podaci su dobijeni iz Registra za maligne tumore centralne Srbije. Analizirani su svi slučajevi malignih tumora velikih pljuvačnih žlezda registrovani u Beogradu od 01. januara 1999. godine do 31. decembra 2010. godine. Trend kretanja i godišnji procenat promene incidencije izračunat je regresionom analizom uz pomoć tačaka spajanja (engl. joinpoint regression analysis). U ispitivanom periodu Registru je prijavljeno je 283 pacijenta (168 muškaraca i 115 žena) sa malignim tumorima velikih pljuvačnih žlezda. Standardizovana stopa incidencije svih tumora u ispitivanom periodu, za oba pola, bila je 0,87/100,000 stanovnika, odnosno 1,13 za muškarace i 0,67 za žene. Standardizovana stopa incidence se uvećavala sa godišnjim procentom promene od 6,4% kod oba pola (p<0,001). Rezultati su pokazali konstantno povećanje trenda incidencije malignih tumora velikih pljuvačnih žlezda kod stanovništva grada Beogradu između 1999. i 2010. godine.
