Abstract: Background: Terrestrial radiation emitted from naturally occurring radionuclides, such as 40K and radionuclides from the 238U and 232Th series and their decay products represent the main external source of irradiation to the human body. The purpose of this study was to provide a preliminary assessment of the doses from terrestrial exposure of population in Serbia and to estimate a potential radiation hazard for population inhabiting investigated areas. Methods: The gamma dose rates, external hazard indexes, and annual effective doses due to terrestrial naturally occurring radionuclides (238U, 232Th and 40K) were calculated based on their activities in soil samples in Serbia as determined by gamma-ray spectrometry. Results: The total absorbed gamma dose rate due to these radionuclides varied from 16.9 to 125 nGy h-1, with a mean of 62.8 nGy h-1. Assuming a 20% occupancy factor, the corresponding annual effective dose varied from 2.07 to 15.4×10-5 Sv with the mean value of 7.7×10-5 Sv, i.e. annual effective dose was in range of the world wide average values. Conclusion: According to the values of external hazard index obtained in this study (mean Hex = 0.35), the radiation hazard was insignificant for the population living in investigated areas.

Abstract: The aim of this research was to compare physicochemical characteristics of honeydew honeys originating from Croatia and Macedonia. 11 samples of Macedonian and 17 samples of Croatian honeydew honey were collected during the harvest season 2005 and 2006, respectively. All collected samples were subjected to the melissopalynological analysis, and afterwards physicochemical characteristics were determined. In comparison with Croatian samples, the samples of Macedonian honeydew honey show statistically significant higher electrical conductivity, prolin content, free and total acidity, glucose and sucrose, as well as fructose and glucose content (F + G), and lower specific rotation, almost negative values. Croatian samples have higher content of maltose (with celobiose and trehalose) and raffinose, until melezitose (with erlose) content in both sample groups is low.

Abstract: Cervical cancer is the most frequently diagnosed malignant disease in pregnancy. The clinical symptoms are scarce or none. The diagnosis is made primarily with a cervical smear, as well as a colposcopic examination and directed cervical biopsy. The treatment of cervical cancer depends on the stage of the disease, the gestation period, and a patient’s wish to carry a pregnancy to term. The illustrated case is of a patient who with the diagnosed presence of microinvasive squamous cell cancer, due to cervical biopsy, in the 1st trimester of pregnancy. In the 2nd trimester, diagnostic conization was performed in order to exclude the presence of the invasive disease. The definite histopathologic findings indicated the presence of cancer in situ. The conization margins were negative and thus the patient was successfully cured. The patient had a cesarean birth in the 36th week of pregnancy and she gave birth to an alive female newborn. Women are given the chance to have cervical cancer diagnosed and treated in the early stages of pregnancy owing to the introduction of a cervical smear in the modern protocol of antenatal protection.

Abstract: Introduction: Prevalence study is simple, cheap and fast method that provides information about hospital-acquired infections (HAI). Objective: To assess the HAI prevalence at different surgical departments in the Clinical Center of Banjaluka. Method: A point prevalence study design was used. All patients (N = 174) hospitalized on July, 1st, 1999 were included in the study. The study was performed by following the CDC guidelines. All patients with clinically manifested infections on the day of study in all surgical departments were recorded. Infections of more than one site in the same patient were considered separate infections. Results: The overall prevalence of patients with HAI was 16.1% (28/174; 95%CI = 10.4-21.6) and the overall HAI prevalence was 18.4% (32/174). Surgical-site infections were the most prevalent (6.3%) followed by skin/soft tissue infections (4.6%) and urinary tract infections (4.0%). More than two thirds (87.5%) of HAI were microbiologically documented. The most commonly isolated microorganisms were Pseudomonas aeruginosa (29.7%), Enterobacter spp. (24.3%) and Staphylococcus aureus (16.2%). Conclusion: This point prevalence study clearly showed the magnitude of HAI problem at different surgical departments in the Clinical Center of Banjaluka, the most prevalent anatomic localizations of HAI, and the most common causes.

Abstract: Introduction. Sj gren's syndrome (SS) is a chronic autoimmune disorder, with its major clinical manifestations resulting from changes in exocrine glands. Objective The aim of this study was to evaluate serum concentrations of circulating immune complexes (CIC) and immunoglobulin G (IgG), and salivary proteins (SP) and salivary immunoglobulin A (sIgA) in 40 patients with SS, and to correlate these values among themselves, as well as with the unstimulated salivary flow rate (USFR) and the duration of disease. Methods. The total of 40 patients were included in this research. CIC was determined using the solution of polyethylene glycol and IgG with the standard procedure of radial immunodiffusion. SP was investigated by the method of Lowry and sIgA was separated from the whole saliva using the method of immune chromatography. Results. The values of most of the studied parameters exceeded the normal range in a high degree: CIC 72.5%, IgG 70%, SP 80%. The concentrations of CIC were significantly higher in the patients with the duration of disease less than 10 years. With the decrease of USFR, the concentration of sIgA and IgG were increased with statistical significance. Conclusion The increased prevalence of abnormal values of CIC, IgG and SP indicate that the patients with SS have developed a higher level of immune reactivity. These results could be useful in diagnosis and disease activity monitoring.

Abstract: The study aimed to estimate the incidence of bites caused by stray and owned dogs in the population of Belgrade, the capital of Serbia in the period from 1st January 2003 to 31st December 2006. Also, the seasonal influence on dog biting was estimated for the same time period. All data on total, stray and owned dog bites in Belgrade in the analyzed period were obtained from the Institute for Infectious and Tropical Diseases of The Medical School in Belgrade and from the Secretariat for Environmental Protection of the City Assembly of Belgrade. The average annual incidence of bites caused by strays was 95.64 per 100 000 residents; 52.84 per 100 000 residents caused by owned dogs and 148.48 per 100 000 residents caused by both categories of dogs. In this period stray dogs caused a significantly higher (P<0.0001) number of bites to humans than owned dogs. The average value for dog bites was 1507.50±143.57/year for strays and 832.75±211.31/year for owned dogs. The highest average value of total dog bites was observed in the spring months in 2005 (263.67±28.01), as well in the spring months (497.33 ± 36.53) for two consecutive years (2005 and 2006). From the aspect of dog bites our results point to the following risk factors for residents in the Belgrade area: the first is the population of stray dogs without owners and the second is the population of irresponsible and uneducated owners of dogs.

Abstract: It seems that the dog overpopulation in Belgrade is similar to that of many other cities in the world. However, Belgrade does not have problems with inhumane stray dogs' population control methods, nor with their malnutrition, nor with inadequate veterinary care. Moreover, Belgrade has a problem with irresponsible and uneducated dog owners, stray and abandoned dogs on the streets and many unlicensed private animal shelters. The next problem is the existence of only one municipal shelter for abandoned, relinquished pets and stray dogs and cats in Belgrade. The first aim of the study was to estimate the total number and the ratio of dogs that were relinquished to the municipal shelter for adoption and for euthanasia in the period from 1st January 2004 to 31st December 2007. The second aim of the study was to estimate the main reasons for relinquishment of owned dogs for adoption and reasons for euthanasia in the municipal shelter in Belgrade. The most owned dogs were relinquished for euthanasia (N=1005; 86.563%). Only 156 dogs (13.437%) were relinquished for adoption. Therefore, the number of relinquished dogs for euthanasia was significantly higher than the number of relinquished dogs for adoption (P<0.001). Financial problems were the most frequently given reasons for relinquishment of dogs to the municipal shelter for adoption (26.92%). The leading cause of relinquishment of dogs to the municipal shelter for euthanasia was incurable illness of aged dogs (25.77%).

Abstract: A significant factor in the protection of consumer health is the systematic and constant implementation of control for the presence of residue of biologically active substances and their metabolites in raw materials and in primary products of animal origin. As regards meat, an essential aspect of security is definitely the control of possible residue of veterinary medicines and environmental contaminants. In that respect, the objective of the national project entitled Development of technology for drying and fermentation of the sausage petrova ka kobasica (Petrovská klobása - registered geographic origin) under controlled conditions“, Number TR - 20037, was to protect the product petrova ka kobasica (Petrovská klobása) with the appropriate appellation. A part of the compulsory investigations also included the establishing of the presence of residue of veterinary medicines and environmental contaminants in raw materials and in the finished product, which was also the aim of this work.

Abstract: The objective of this work was to establish, on the grounds of obtained results for the total number of bacteria before and after completed disinfection, whether there are differences in the efficiency of disinfection performed by a professional and disinfection carried out by an unqualified employee in a private slaughterhouse. The material used in these investigations were samples of wet-dry swabs taken over a course of five weeks, before and after disinfection carried out by an unqualified employee and the skilled professional, from the following: the knife used for evisceration, the floor in the evisceration area, from the table serving for bristle removal, and from the floor underneath the bristle removal surface. The wet-dry swabs were taken according to the procedure described in the standard method ISO 18593 (Microbiology of food and animal feeding stuffs - Horizontal methods for sampling techniques from surfaces using contact plates and swabs). Analyzing the taken samples, the total number of bacteria was determined using the standard method ISO 4833 (Microbiology of food and animal feeding stuffs - Horizontal method for the enumeration of microorganisms - Colony-count technique at 30°C). Disinfection was carried out using a chlorine preparation (sodium dichloroisocyanurate dihydrate) in a concentration of 0.02% and for an exposure period of 30 min. The results were interpreted on the grounds of the border values in evaluating the hygiene of the equipment, tools, and work surfaces, presented in Commission Decision 471/2001/ EC. The results of the investogations have shown that the disinfection performed by the skilled professional was more efficient than the disinfection performed by the unqualified person, as the total number of bacteria was significantly smaller (p<0.01) in the course of all 5 experimental weeks on the evisceration knife, the floor under the bristle removal surface, during weeks 1, 2 and 5, and on the floor in the evisceration area in weeks 1 and 5.

Abstract: Background/Aim. Detection of metastatic bone disease by skeletal scintigraphy is a classical application of nuclear medicine in cancer patients. Detection of bone metastases in patients with lung cancer is necessary for an appropriate treatment modality. The aim of this study was to report the frequency and imaging characteristics of bone metastases detected by bone scintigraphy (BS) using technetium-99m phosphonates in patients with lung cancer. Methods. We retrospectively analyzed a total of one hundred patients (78 males and 22 females), mean age of 63.3 years, with the diagnosis of lung cancer, who underwent BS during a three-year period (2003 2005). Scintiscans were classified as positive, negative and suspicious with regard to the presence of bone metastases. Results. The incidence of positive, negative and suspicious findings were 57%. 32% and 11%, respectively. Out of 57 patients with bone metastases, 51 had multiple asymmetric foci of increased tracer activity localized in the ribs, spine, extremities, pelvis, sternum, scapula and skull in 72%, 54%, 49%, 37%, 12%, 9% and 5% of scans, respectively. BS revealed solitary metastases in 6 of the patients. The lesions were located in the lower limbs in three patients and in the upper limbs, pelvis and sternum in the remaining three patients. Conclusion. Bone scintigraphy plays a significant role in staging and selecting of patients for curative lung surgery. Due to the fact that metastatic involvment of the extremities was frequently shown, our study suggests that systematic inclusion of the limbs in BS acquisition should be obligatory.
