Introduction: Unintentional falls are the leading cause of traumatic injuries, without fatal consequences, with significant morbidity in the population of children and adolescents. Goal: The main goal of this research was to analyze the manner of falling in relation to age and gender, and to assess the type of injury and the anatomical region of the body affected by the injury sustained during a fall in patients ≤19 years of age treated in the emergency medical services in the Republic of Srpska. Material and methods: A cross-section study with retrospective analysis of the national e-database WebMedic from 11 emergency medical services between January 2018 and December 2020 was conducted. Research included patients with diagnosis of unintentional injury caused by a fall, aged ≤19 years. Descriptive statistics and the Chi-square test were used for comparisons between groups. Results: During the observed period, 857 cases of unintentional falls were identified, where 87.5% were referred for hospitalization. The group of children aged 0 to 9 years (55.7%) was more often treated for falls (p<0.001), and boys were affected 6.7 times more often than girls (p<0.001). Falls from the same level caused different types of injuries depending on the age and gender of the children (p<0.001). According to the type of injury, superficial injuries (36.8%) and open wounds (29.4%) were most often identified, and the most frequently affected body region was the head (52.0%). Conclusion: The group of children up to the age of nine and males were more often affected by superficial injuries and open wounds, with head injuries being predominant in all age groups. These results could indicate the necessity of creating programs with targeted prevention.

Background/Aim: With the adoption of legislation over the Austro-Hungarian rule (1878-1918) apothecary in Bosnia and Herzegovina (B&H) became a regulated profession, which enabled the arrival of graduated pharmacists. The aim of the paper was to present in which towns on the B&H territory public pharmacies were opened over this period and their owners. Methods: A retrospective and descriptive research was conducted at the Archives of the Republic of Srpska, the Museum of the Republic of Srpska and the Archives of Bosnia and Herzegovina. The method of the qualitative secondary data analysis was applied. Results: With the arrival of Masters of Pharmacy from all parts of the Austro-Hungary, an increasing number of public pharmacies began to open. Concessions for the opening pharmacies were initially granted to foreigners and among the settlers, pharmacists there were mostly Czechs, Croats, Poles, Hungarians, Slovaks, who completed pharmacy studies at universities in Vienna, Zagreb, Prague, Lviv, Graz, Innsbruck, Krakow. In the beginning, there were no locally educated pharmacists and the first appeared at the end of the 19th and the beginning of the 20th century. During this period at least one pharmacy was opened in many towns, two worked in Banja Luka, Mostar, Tuzla and Bijeljina and seven in Sarajevo. In the first years, each pharmacy was staffed by only one pharmacist and over time there were more pharmacy staff in the pharmacies. Twenty years after the occupation, public pharmacies owned by Masters of Pharmacy were opened in thirty three towns around B&H and in 1918 there were forty eight public pharmacies in thirty eight towns. Conclusion: The number of public pharmacies and qualified pharmacy staff in B&H increased over the Austro-Hungarian rule from 1878 to 1918, which contributed to the improvement of the profession, health and social conditions in the country during this period.

Background / Aim: Up until ten years ago stage four melanoma was considered a disease with extremely poor prognosis. Standard therapy during this period of time was dacarbazine chemotherapy. Patients with better performance status were treated with immunotherapy cytokine IL-2. In the last ten years eight medications have been approved by the FDA for the therapy of melanoma. The goal of this study was to determine objective response rate (ORR), median overall survival (OS), median progression free survival (PFS) and safety in patients with advanced and metastatic cutaneous melanoma treated with targeted therapy and immunotherapy at the University Clinical Centre of the Republic of Srpska (Centre). Methods: A non-randomised observational retrospective/prospective trial was conducted to investigate first experiences with the use of targeted therapy and immunotherapy at the Centre and compare the results with the literature data. A total of 23 patients received BRAF targeted therapy for the treatment of metastatic cutaneous melanoma in the first line of treatment. Nine patients received vemurafenib, fourteen patients received a combination of BRAF/MEK inhibitor. Nine patients were treated with pembrolizumab immunotherapy. The trial was performed in a period from May 2017 until December 2020. Results: In patients receiving vemurafenib ORR was 44.4 %, median PFS was 5 months (95 % CI, 1 to 11) and the median OS was 9 months (95 % CI, 2 to 17). In the vemurafenib/cobimetinib group ORR was 71.4 %. Median PFS was 9 months and median OS was 12 months. ORR in patients receiving pembrolizumab was 22.9 %, median PFS was 3 months (95 % CI, 1 to 11) and the median OS was 4.5 months (95 % CI, 2 to 12). Results in all three groups were inferior compared to the results from the literature except for ORR in patients receiving vemurafenib and vemurafenib/cobimetinib. Adverse events were tolerable and manageable and were similar to those described in the literature. Conclusion: Based on the experience with the targeted and immunotherapy in the Centre, which was presented in this study, it was concluded that in conditions when there is limited access to drugs, the greatest benefit have the patients who meet the inclusion criteria in clinical trials.

The aim of the present study is to improve the solubility and antimicrobial activity of 3-(3-(2-chlorophenyl)prop-2-enoyl)-4-hydroxycoumarin by formulating its inclusion complexes with 2-hydroxypropyl-β-cyclodextrin in solution and in solid state. The phase solubility study was used to investigate the interactions between 3-(3-(2-chlorophenyl)prop-2-enoyl)-4-hydroxycoumarin and 2-hydroxypropyl-β-cyclodextrin and to estimate the molar ratio between them. The structural characterization of binary systems (prepared by physical mixing, kneading and solvent evaporation methods) was analysed using the FTIR-ATM spectroscopy. The antimicrobial activity of 3-(3-(2-chlorophenyl)prop-2-enoyl)-4-hydroxycoumarin and inclusion complexes prepared by solvent evaporation method was tested by the diffusion and dilution methods on various strains of microorganisms. The results of phase solubility studies showed that 3-(3-(2-chlorophenyl)prop-2-enoyl)-4-hydroxycoumarin formed the inclusion complexes with 2-hydroxypropyl-β-cyclodextrin of AP type. The solubility of 3-(3-(2-chlorophenyl)prop-2-enoyl)-4-hydroxycoumarin was increased 64.05-fold with 50% w/w of 2-hydroxypropyl-β-cyclodextrin at 37 o C. The inclusion complexes in solid state, prepared by the solvent evaporation method, showed higher solubility in purified water and in phosphate buffer solutions in comparison with 3-(3-(2-chlorophenyl)prop-2-enoyl)-4-hydroxycoumarin alone. The inclusion complexes prepared by solvent evaporation method showed higher activity on Bacillus subtilis and Staphylococcus aureus compared to uncomplexed 3-(3-(2-chlorophenyl)prop-2-enoyl)-4-hydroxycoumarin due to improved aqueous solubility, thus increasing the amount of available 3-(3-(2-chlorophenyl)prop-2-enoyl)-4-hydroxycoumarin that crosses the bacterial membrane.

This review mainly focuses on nanoparticle-based drug delivery systems fabricated from plants (starch, cellulose, pectin), animals (chitosan, gelatin) and microorganisms (dextran). Herein, the focus is on the physical-chemical properties of biopolymers and its derivatives and the mechanism of action in the treatments of cancer. Nanoparticle-based drug delivery systems improved efficacy by: increasing half-life of vulnerable drugs and proteins, improving the solubility of hydrophobic drugs, and allowing controlled and targeted release of drugs in diseased site. Of all the mentioned biopolymers, only dextran and pure pectin are problematic. Some clinical studies have shown unexpected side effects caused by dextran such as thrombocytopenia and hepatotoxicity and, pure pectin-based materials, undesirable swelling and corrosion properties. Doxorubicin has been used in combination with almost all of these biopolymers because it is widely used as an effective chemotherapeutic agent in the treatment of many types of solid tumors of the breast, lung, colon, ovary, prostate and bladder.

Recently, nanotechnology is widely used in agriculture with the aim of achieving high agricultural yields. Due to the unique surface and physicochemical properties, nanomaterials can be used to deliver nutrients to plants via nanoparticles, for the synthesis of nanopesticides, nanofungicides, and to design nanosensors for the detection of very low concentrations of pesticides and other contaminants. Excessive use of pesticides and fertilizers causes the loss of soil biodiversity and the development of resistance to pathogens. Nenoencapsulation of fertilizers, pesticides and herbicides is used for slow and specific dosed release of nutrients as well as agrochemicals. This paper discusses the applications of nanotechnology and their positive effect in agriculture in relation to the common methods used so far.

Introduction/Objective Cat bites can seriously harm human health, especially if the bite comes from a stray or feral cat who is not under veterinary supervision. Cat bites are the second most common mammal bites, second only to dog bites, and responsible for ¾ of all bites that result in infection. We are presenting the case of a young woman whose hand had been bitten by a stray or feral cat. The objective of this case study is to stress the importance of timely medical treatment and wound management based on guidelines for treating bites inflicted by stray or feral cats, aiming to prevent possible complications. Case report A 32-year-old woman was admitted and examined in the University of Sarajevo Clinical Centre Emergency Department on the third day after being bitten by a stray or feral cat, by which time all signs of inflammation had already developed at the site of the injury-her right hand. Medical help was provided based on guidelines that included specific wound dressings recommended for animal bites, a prescription of antibiotics, analgesics and an anti-tetanus shot. The patient fully recovered with no complications. Conclusion The specific anatomy of the cat's canines enables them to penetrate deeply into the bitten tissue, which can cause an innoculation of a wide range of microorganisms from the cat's mouth into the patient's bloodstream. This can cause serious inflammatory processes, especially in immunocompromised patients. Adequate medical treatment of injuries resulting from cat bites is necessary as soon as possible, but no later than 48 hours after the incident.
