Abstract: Asphyxia i a condition caused by lack of oxygen in tissues and organs. The basic pathogenic mechanisms of asphyxia are: 1)hypoxemia, 2) ischemia. The effects of perinatal asphyxia on the brain of a neonatal baby are critical in development of hypoxic-ischemic encephalopathy. The diagnosis of hypoxic-ischemic encephalopathy is based on clinical data including course of pregnancy and delivery (Apgar score) and especially on the neurological status of the newborn (consciousness, tonus, convulsions, reflexes, vegetative functions, etc.) and it can be confirmed by biochemical analysis and neurological examinations. The aim of this paper is to determine the importance of prenatal and perinatal risk factors for hypoxic-ischemic encephalopathy, as well as their effects on the development of neurological complications and further neurological problems. The research included 148 newborn infants born in the period from January 1, 1996 to January 1, 1999, with gestational age of 27 to 42 weeks, with hypoxic ischemic lesions of the central nervosus system. The control group included 58 children of the same age and the same gestation, with generalized hypotonia ("floppy infant") but without any signs of hypoxic ischemic lesions of the central nervous system. In the group of examined newborn infants with hypoxic ischemic lesions, from 149 children 1 (0.67%) died, 87 (53.89%) had normal findings, whereas the handicap was established in 61 (40.94%). Perinatal asphyxia affects the fetus and newborn infants not by individual factors, but with at least three or four associated factors. The disorders caused by asphyxia are in inverse proportion to the duration and intensity of hypoxic insults and the gestational age of the newborn. .

Abstract: The establishment of policies and incentives for the issuance and card acceptance worldwide is the necessary basis for the development of card based payment instruments. Multilateral interchange fees (MIF) played a major role in creating the appropriate sets of incentives for acceptance and issuance while balancing the interests of market participants. The goal of this paper is to present the developments in the area of MIF regulation across the European Member States, as well as in Serbian payment cards market, and to suggest the way forward towards possible Serbian payment systems participation in the Single European Payment Area (SEPA) in the future.

Abstract: Background/Aim. Multiple sclerosis (MS) is an immunemediated central nervous system disease characterized by inflammation, demyelination and axonal degeneration. Cytokines are proven mediators of immunological process in MS. The aim of this study was to investigate whether there is a difference in the production of the tumor necrosis factor alpha (TNF-alpha) and interleukin-4 (IL-4) in cerebrospinal fluid (CSF) and plasma in the MS patients and the controls (other neurological non-inflammatory diseases) and to determine a possible difference in these cytokines in plasma and CSF in different clinical forms of MS. Methods. This study involved 60 consecutive MS patients - 48 patients with relapsing-remitting MS (RRMS) and 12 patients with secondary progressive MS (SPMS). The control group consisted of 20, age and sex matched, nonimmunological, neurological patients. According to the clinical presentation of MS at the time of this investigation, 34 (56.7%) patients had relapse (RRMS), 14 (23.3%) were in remission (RRMS), while the rest of the patients, 12 (20.0%), were SPMS. TNF-alpha and IL-4 concentrations were measured in the same time in CSF and plasma in the MS patients and the controls. Extended disability status score (EDSS), albumin ratio and IgG index were determined in all MS patients. Results. The MS patients had significantly higher CSF and plasma levels of TNF-alpha than the controls (p < 0.001 for both samples). IL-4 CSF levels were significantly lower in the MS patients than in the controls (p < 0.001), however plasma levels were similar. The patients in relapse (RRMS) and with progressive disease (SPMS) had higher concentrations of CSF TNF-alpha levels than the patients in remission (p < 0.001). IL-4 CSF levels in relapse (RRMS) and SPMS groups were lower than in the patients in remission. The patients in remission had an unmeasurable plasma TNF-alpha level and the patients with SPMS had significantly lower IL-4 levels in plasma than the patients in relapse and remission (p < 0.001). The only significant correlation between cytokine level with either EDSS, or albumin ratio, or IgG index, was found between CSF TNF-alpha levels and albumin ratio in the patients with relapse (R square = 0.431, p < 0.001). Conclusion. According to the obtained data MS relapse was characterized by high concentrations of TNF-alpha in CSF and plasma and low concentrations of IL-4 in CSF. Remission was characterized by high concentrations of IL-4 and low concentrations of TNF-alpha both in CSF and plasma. SPMS was characterized with lower concentrations of TNF-alpha

Abstract: Introduction. Takotsubo cardiomyopathy is a transient acute heart failure syndrome caused by stress that provokes left ventricular mid-apical akinesis and mimics acute coronary syndrome. Case report. A 66-year-old woman had chest pain and dispnoea a few hours before hospitalization. A sudden emotional stressful event preceded the symptoms. Electrocardiographic abnormalities - precordial ST elevation and modest increase of cardiac troponin mimiced acute myocardial infarction. However, echocardiographic examination showed apical ballooning with markedly diminished left ventricle ejection fraction and the obstruction in the outflow tract of the left ventricle. Coronary angiography at admission showed no coronary stenosis and slower blood flow through the left anterior descending artery. According to anamnesis, echocardiography and coronarography finding we established the diagnosis of stress cardiomyopathy - takotsubo cardiomyopathy. We described in details the slow but dynamic electrocardiographic changes, levels of brain natriuretic peptide, cortisol and echocardiography evolution of disease during a 4-month follow-up till the full recovery. Conclusion. Stress (takotsubo) cardiomyopathy - became an important differential diagnosis of acute anterior myocardial infarction and it should be reconsidered every time when emotionally stressed patients with transient-apical akinesis or dyskinesis of the LV are present.

Abstract: Brain abscesses were neurosongraphically diagnosed in 3 out of 44 neonates who had confirmed purulent meningitis. In two cases, the cause was Proteus mirabillis, whereas in one the cause could not be isolated. The ultrasound finding indicated abscess cavities localized in the frontal (in one case bilaterally) and temporal regions of the CNS. Neurosurgical interventions were carried out on all of the neonates who had abscesses (including the evacuation of purulent cavity contents, and later on a ventriculoperitoneal shunt in two cases, because of the development of hydrocephalus). Follow-up on the operated infants revealed that one infant died at the age of 9 months; one, who had a bilateral abscess, demonstrated significant neurodevelopmental retardation in the third month of his life (so far it has not been brought under control); while the third one, whom we monitored until the age of 2, displayed regular psychomotor development (preserved intellect, motor skills, sight, and hearing).

Abstract: Anticholinergic drugs block muscarinic effect of acetylcholine on the receptors of postjunctional membranes and so inhibit the answer of the postganglionic parasympathetic nerve. The loss of M2 muscarinic receptors function occurs in asthmatics and it contributes to bronchial hyperresponsiveness and it is not a chronic feature of asthma, instead it characterizes asthma exacerbation. The loss of M2 muscarinic receptor function in children and adults happens during antigen bronchoprovocation or during exposition of asthmatics to ozone. After inhalation, ipratropium bromide (IB) can be found in a small quantity in circulation and it links less readily to muscarinic receptors on airway smooth muscles as related to its absorption after intravenous application. In the stepwise approach of asthma inhaled anticholinergics is recommended if the symptoms of the disease cannot be adequately controlled by a regular inhalation of antiinflammatory drugs with β2-agonist and oral steroids. The improvement of the airway inspiratory capacity is more elevated than the improvement of FEV1 after inhalation of IB. IB has similar effect as salbutamol and it is recommended to control a stable chronic obstructive disease. During our numerous investigations and up-to-date experience in the usage of 5-7 μg/kg/body mass of IB repeated every 4-6 hours in combination with salbutamol, we did not notice adverse effects of the drug in infants. IB is recommended for hospital treatment of children. .

Abstract: Numerous epidemiological studies, conducted in both developed and developing countries, have shown that the rotavirus is an important aetiological agent in severe diarrhoeal diseases among preschool children. In recent years, different biochemical techniques for the genetic and phenotypic analysis of rotaviruses have been developed. The aim of this study was to define the biological and genetic differences among rotaviruses isolated from the faeces of affected children, by using the Polyacrylamide Gel Electrophoresis technique, as well as to type the viruses and establish the number of strains circulating within our population. In total, 124 faeces samples from children up to 5 years of age were analysed. With the use of the ELISA test, rotaviruses were isolated in 10.3% of cases. The extraction of viral RNA was carried out directly from the faeces samples, which was followed by electrophoresis, and finally observation using a UV lamp, and documentation with a photo camera. The analysis of viral RNA, using Polyacrylamide Gel Electrophoresis (PAGE), revealed equal mobility in all segments of the genome. The results of our analysis demonstrated that the same strains of rotaviruses do circulate within our population. Such a result can be explained as a consequence of our years-long isolation as well as of the decreased mobility of our population. However, the results do not signify that the rotavirus genome in this region will not be susceptible to variations and that, consequently, new strains will not be created.
