Abstract
AIM The aim of the present study was to establish annual prevalence of primary headaches, migraine, and tension-type headache among adults in a post-conflict area of Serbia. METHODS The data for this cross-sectional study was obtained via face-to-face interviews using questionnaires specifically designed for this purpose, in line with the available guidelines. The study sample included adults aged 18-65 years whose native language is Serbian with residence in six predominantly Serbian communities in Kosovo and Metohija. Relevant diagnoses were established according to the diagnostic criteria of the International Classification of Headache Disorders, 3rd edition. RESULTS The study included 1062 adults. Analyses indicated 47.7% prevalence of primary headaches. The 1-year prevalence of migraine (with aura and without aura) and tension-type headache was established at 15.2% (3.3% and 11.9%), and 32.2%, respectively. One-year prevalence of chronic headache was calculated at 3.5%, while the prevalence of medication overuse headache was slightly lower at 2.9%. Primary headaches were more prevalent among women, participants residing south of the river Ibar, married or cohabiting individuals, as well as among interviewees (persons) who reported feeling unsafe in Kosovo and Metohija. This is the first study of the prevalence of primary headache disorders in Serbia. The obtained data is comparable to the data available for other countries, especially those in the Balkan region.

Abstract
Although cerebrovascular disease may be a well recognised trigger for diabetic ketoacidosis (DKA), literature data on the precise mechanisms, characteristics, or treatment guidelines are rare. The risk of developing an ischemic stroke is doubled in adults with diabetes compared to people with normal glucose metabolism. It is important to point out that even children with DKA have a significantly increased risk of cerebrovascular insult and that they can have a stroke with a frequency of about 10%. Given the significant overlap of symptoms between these two diseases, it can be assumed that attributing DKA symptoms as a manifestation of stroke is not uncommon, especially in elderly and less communicative patients. In addition, pH, bicarbonate concentration, and anion gap are not routinely measured in all diabetics suffering from stroke, at least not in secondary health institutions.Children who develop cerebrovascular stroke during DKA often at the beginning have a preserved consciousness or only mild confusion or lethargy. After a few hours, with the institution of therapy, however, loss of consciousness may occur accompanied by signs of increased intracranial pressure. It was previously thought that the cause was too fast fluid replacement. Recent data suggest that reperfusion injury may be a more likely mechanism. Although most of these studies relate to younger individuals with ketoacidosis, it is clear that at least some of them may be operative in adult DKA. Literature therapeutic guidelines for adult diabetics with stroke-related diabetic ketoacidosis are almost lacking, although it is clear that they could not be the same as those utilised in population with normal glucose metabolism. In this paper, we have tried to define our treatment guidelines for these particular patients.

Abstract
Thyroid storm is an acute and severe complication of thyrotoxicosis. It is characterized by high fever, sweating, tachycardia, and often heart failure too. The objectives of the paper is to present the case of a patient with thyroid storm developed after the trauma of the chest at previously apparently healthy individuals, diagnosed on the basis of clinical preview and based on the diagnostic criteria according to Burch and Wartofsky. The most common complication is Mb. Graves - Basedow, but often associated with multi-nodose goiter. Thyroid storm is the most severe form of thyrotoxicosis with a mortality rate of 8 to 25 %. Case report. We present an interesting case from our practice: thyroid storm caused after chest trauma in apparently healthy people, but with unrecognized hyperthyroidism and thyroid gland nodule. Conclusion. The objectives of this presentation were to raise awareness of the association between signs and symptoms of thyroid storm that dominate the clinical picture and complicate the initial presentation and the evolution of the situation caused by trauma. The treatment of hyperthyroidism resulted in conversion in sinus rhythm, withdrawal of symptoms and signs heart failure, and normalization of artery pressure.

Abstract
Liver cholestasis is known to accompany several major liver disorders and is adequately mimicked in rats by ligation of the bile duct (BDL). L-arginine is a semi-essential amino acid which is involved in several important metabolic pathways that are significantly affected during cholestasis. This study was conducted in order to contribute to the understanding of the enrolment of L-arginine supplementation in cholestatic liver function. This was carried out by estimation of serum and liver tissue arginase activity, along with liver tissue citrulline, nitric oxide (NO) and polyamine concentrations. Rats subjected to BDL were treated for nine days with L-arginine (150 mg/kg) or remained without any treatment. Animals from two control groups were either subjected to medial laparotomy (sham/opened group) or were without any surgical treatment and received only L-arginine. Application of L-arginine prevented a significant increase in plasma bile acid and bilirubin concentrations, as well as enzyme biochemical markers that were increased after BDL. It is worth mentioning that L-arginine was able to cause a decrease in arginase activity and liver tissue NO concentrations that were found to be significantly altered during cholestasis. On the other hand, the changes occurring in the concentration of liver polyamines (putrescine, spermidine and spermine) and the activity of polyamine metabolizing enzymes were not notably affected by the administered L-arginine. The results of the present study revealed that exogenous L-arginine was able to ameliorate or prevent changes occurring in its metabolism in liver during cholestasis.

Abstract
AIMS The present study was designed to compare the ameliorating potential of pre- and post-treatments with melatonin, a potent natural antioxidant, in the carbon tetrachloride-induced rat liver damage model by tracking changes in enzymatic and non-enzymatic liver tissue defense parameters, as well as in the occurring pathohistological changes. MAIN METHODS Rats from two experimental groups were treated with melatonin before and after CCl4 administration, while the controls, negative and positive, received vehicle/melatonin and CCl4, respectively. Serum levels of transaminases, alkaline phosphates, γ-GT, bilirubin, and albumin, as well as a wide panel of oxidative stress-related parameters in liver tissue, were determined in all experimental animals. Liver tissue specimens were stained with hematoxylin and eosin and further evaluated for morphological changes. KEY FINDINGS Both pre- and post-treatment with melatonin prevented a CCl4-induced increase in serum (ALT, AST, and γ-GT) and tissue (MDA and XO) liver damage markers and a decrease in the tissue total antioxidant capacity, in both enzymatic and non-enzymatic systems. The intensity of pathological changes, hepatocyte vacuolar degeneration, necrosis and inflammatory cell infiltration, was suppressed by the treatment with melatonin. SIGNIFICANCE In conclusion, melatonin, especially as a post-intoxication treatment, attenuated CCl4-induced liver oxidative damage, increased liver antioxidant capacities and improved liver microscopic appearance. The results are of interest due to the great protective potential of melatonin that was even demonstrated to be stronger if applied after the tissue damage.

Abstract
Psoriasis severity varies by body region, with each affected region having a different impact on patient quality of life (QoL). The aim of this study was to assess the impact of changes in the Psoriasis Area and Severity Index (PASI) scores by body region on QoL in patients with psoriasis after treatment. A total of 100 patients with psoriasis were recruited to the study. All patients completed the generic EuroQol-5D instrument and two specific QoL measures, Dermatology Life Quality Index (DLQI) and Psoriasis Disability Index (PDI) at the beginning of the study, and 50 patients successfully completed the same questionnaires four weeks after the end of the treatment. Clinical severity was assessed using PASI total score and PASI body region (head, trunk, arms, and legs) scores. QoL improved after treatment, and PASI improvements on visible body regions (head, legs, and arms) showed significant correlation with the most sub-areas of the Visual Analog Scale (EQ VAS), DLQI, and PDI. Multiple linear regression analysis revealed that PASI improvement (particularly on the head), sex, age, and disease duration were predictors of QoL score changes for most domains of the three instruments. Improvement of psoriasis in visible body regions has an appreciable influence on QoL improvement, and may positively affect treatment success in patients with psoriasis.

Abstract
<p>The desorption behavior of <em>β</em>-carotene from a bentonite adsorbent under microwave irradiation in isopropanol was studied as a function of temperature and different initial loading concentrations. A first-order, two-component, three-parameter model described the desorption kinetics with a coefficient of determination <em>R</em><sup>2</sup> > 0.9932, and the <em>β</em>-carotene desorption process under microwave irradiation was controlled by both rapid and slow desorption. The activation energies of <em>β</em>-carotene desorption for the rapid and slow desorption processes were 19.61 and 53.04 kJ mol<sup>–1</sup>, respectively. It was observed that the desorption equilibrium data fitted well to both the Freundlich and Langmuir isotherms. The data obtained from the desorption-isotherm model were used to determine the thermodynamic parameters. The positive value of free energy indicates the non-spontaneity of <em>β</em>-carotene desorption. The change in entropy relative to the enthalpy of desorption reveals that the reaction is physical in nature.</p>

Abstract
INTRODUCTION Clinical, epidemiological and biochemical studies strongly support the concept that the non-alcoholic fatty liver disease is a hepatic manifestation of the metabolic syndrome. Insulin resistance is a common factor connecting obesity, diabetes, hypertension and dyslipidemia with fatty liver and the progression of hepatic disease to steatohepatitis, fibrosis, cirrhosis and hepatocellular carcinoma. Since identification of cardiovascular risk factors is the first step in their prevention, the aim of this study was to analyze the prevalence of some risk factors in patients with fatty liver. MATERIAL AND METHODS The study included 130 patients who met metabolic syndrome criteria; their demographic and anthropometric characteristics were analyzed and some clinical characteristics were determined, such as smoking habit, arterial pressure and alcohol intake. Routine biochemical analyses were carried out by a standard laboratory procedure. Hepatic steatosis was detected by the abdominal ultrasound. Modified criteria of the National Cholesterol Education Program Adult Treatment Panel III were used to describe the metabolic syndrome. RESULTS The study group consisted of 72 subjects (55.38%), who had been found by ultrasound to have fatty liver, whereas the control group included 58 respondents (44.62%) without pathological ultrasound findings. Differences in the number of fatty liver were highly statistically significant between the groups. The values of body mass index (33.56 +/- 6.05 vs 30.56 +/- 4.23 kg/m2; p = 0.001), glucose (6.23 +/- 0.95 vs 5.76 +/- 0.88 mmol/l; p < 0.01) and cholesterol (6.66 +/- 1.30 vs 6.23 +/- 0.95; p < 0.05) were significantly higher in the patients with fatty liver than in those without fatty liver. CONCLUSION Our results indicate that the patients from the study group had a high percentage of cardiovascular risk factors.

Abstract
The methodology of quantitative aerobiological control is described and the results of measurements of the intensity and character of air contamination are commented for several places of general surgical ward. The importance of such a control is stressed in the context of general efforts to improve the quality of air in hospitals, to prevent air contamination and decrease the incidence of aerogenic infections. The results of those measurements show that the intensity of air contamination is corresponding to the total volume of physical activity in a milieu. In some very delicate hospital areas (dressing units and operating theatres), the concentration of aerosol sometimes exceeds its permitted level and if this is a case, it is advised to take all possible measures of protection to prevent air contamination and aerogenic infections. It is also found out that at the very beginning of physical activity, there is predominance of relatively big aerosol fractions in air, but soon this predominance is diminished because of the elimination of those fractions by sedimentation.
