Lymphangiomas are benign vascular malformations of the lymphatic system and most commonly present in the neck area. Large lymphangiomas may compress and/or displace the larynx, trachea and esophagus and cause serious respiratory and feeding problems in neonates. Prenatal therapy could eliminate the risks of the mentioned complications. Prenatal therapy may include the EXIT (ex utero intrapartum treatment) procedure. As this procedure has certain risks for both the neonate and mother, the introduction of a safer method is justified. The use of OK-432, as a sclerosing agent, has shown positive results in several published cases of cystic hygroma, but there is no study about the prenatal use of this agent in the treatment of lymphangioma. The aim of this study was to present our experience with intrauterine intralesional injection of OK-432 in the treatment of neck lymphangiomas. Two cases of large multicystic neck lymphangiomas that were closely situated to the fetal airway were treated by single intralesional injection of OK-432. We noticed a progressive decrease in tumor volume throughout gestation. We did not experience any complications and there were no respiratory or feeding problems in the neonates. The esthetical appearance was satisfactory and both children were normal at the age of 2 years and 6 months, respectively. This report suggests that prenatal intralesional injection of OK-432 might be a safe and effective treatment in selected cases with large fetal neck lymphangiomas.

Background: Metamizole is a medication with analgesic, antipyretic, spasmolytic, and weak anti-inflammatory effects. The aim of our study was to evaluate a six-year trend in the utilization and expenditure of metamizole in comparison to other group of licensed non-opioid analgesics in Serbia and Croatia, in order to rationalize its use and prescribing in these countries.Methods: The data of metamizole vs. all other non-opioid analgesics utilization and expenditure in Serbia and Croatia was analyzed according to the WHO methodology and expressed as defined daily doses per 1,000 inhabitants per day (DDD/1,000 inhabitants/per day) and total costs, respectively, during the 6-year period from 2010 to 2015.Results: In the observed period, utilization of metamizole was 3.31 fold higher in Serbia than in Croatia (median in Serbia was 2.238 vs. 0.675 in Croatia DDD/1,000 inhabitants/per day/per year). Expenditure of metamizole in the same period was 5.29-fold higher in Serbia than in Croatia (median in Serbia was 1,738,192.51 €/per year vs. 328,355.03 €/per year in Croatia).Conclusion: Utilization and expenditure of non-opioid analgesics, including metamizole, in Serbia was significantly higher comparing with Croatia.Further research is needed to determine whether the current analgesic consumption in Serbia meets the needs of the patient. The benefits of metamizole should be weighed against the risk of metamizole-induced adverse effects. Until then, its prescribing should be based on indications and the appropriate duration of therapy.

Cardiovascular diseases, including ischemic heart disease, are the most common causes of morbidity and death in the world, including Serbia, as a middle-income European country. The aim of the study was to determine the costs of preventive examinations for ischemic heart disease in active-duty military personnel, as well as to assess whether this was justified from the point of view of the limited health resources allocated for the treatment of the Republic of Serbia population. This is a retrospective cost-preventive study which included 738 male active-duty military personnel, aged from 23 to 58. The costs of primary prevention of ischemic heart disease in this population were investigated. Out of 738 subjects examined, arterial hypertension was detected in 101 subjects (in 74 of them, arterial hypertension was registered for the first time, while 27 subjects were already subjected to pharmacotherapy for arterial hypertension). Average costs of all services during the periodic-health-examination screening program were €76.96 per subject. However, average costs of all services during the periodic-health-examination screening program for patients with newfound arterial hypertension and poorly regulated arterial hypertension were €767.54 per patient and €2,103.63 per patient, respectively. Since periodic-health-examination screening program in military personnel enabled not only discovery of patient with newfound arterial hypertension but also regular monitoring of those who are already on antihypertensive therapy, significant savings of €690.58 per patient and €2,026.67 per patient can be achieved, respectively. As financial resources for providing health care in Serbia, as a middle-income country, are limited, further efforts should be put on screening programs for ischemic heart disease due to possible significant savings.

Colorectal cancer (CRC) is one of the most commonly diagnosed malignant neoplasms. The aim of the study was to evaluate and correlate most important epidemiological and economic indicators of CRC in 11 selected Balkan countries. The number of new CRC cases was 56,960, and the highest 5-year CRC prevalence was in Slovenia, Croatia, and Greece. Age-standardized CRC incidence rates were highest in Slovenia, Serbia, and Croatia, and age-standardized mortality rates were highest in Croatia, Serbia, and Bulgaria. Current Health Expenditure as % of Gross Domestic Product was the highest in Bosnia and Herzegovina and Serbia. The GDP per capita levels have shown positive correlation with the CRC incidence rate and prevalence. Absolute numbers of new and death-related CRC cases and 5-year prevalence in absolute numbers have shown strong positive correlation with GDP in million current US$. It has been shown that various economic indicators can be linked to the rate of incidence and prevalence of the CRC patients in the selected Balkan countries. Therefore, economic factors can influence the epidemiology of CRC, and heavy CRC burden in the Balkan region may be one of the indexes of the economic development.
