Using natural and modified Ca-bentonite as an adsorbent to observe a satisfactory trend in the removal of heavy metal ions As(V) and Hg(II) from simulated wastewaters. In this original scientific paper, Ca-bentonite was modified in two ways, thermally activated at a temperature of 300 °C for 3 hours and acid activated with HCl and H2SO4, molar concentrations 0,4 mol/L. Ca-bentonite used in this original scientific work was used from the Shipovo mine (Šipovo mine), Bosnia and Herzegovina and proved to be an excellent bioadsorbent for the removal of present ions from simulated wastewaters. Also this is eco-friendly adsorbent and low costed compared to other expensive adsorbents. Due to its chemical composition in which two oxides predominate, namely SiO2 (48.28 mass %) and Al2O3 (23.04 mass%), it can be concluded that Ca-bentonite from the Shipovo mine (Šipovo mine), Bosnia and Herzegovina belongs to the group of refractory materials. The highest removal efficiency of As(V) ions expressed in % was 75.11 at the initial concentration of 1.5 mg/L and was recorded using HCl acid-activated Ca-bentonite. The efficiency of Hg(II) ion removal was the highest using thermally activated Ca-bentonite and this value was 99.66% at an initial concentration of 1 mg/L.

Determining the demographic characteristics of a person post-mortem is a fundamental task for forensic experts, and the dental system is a crucial source of those information. Those characteristics, namely age and sex, can reliably be determined. The mandible and individual teeth survive even the harshest conditions, making them a prime target for forensic analysis. Current methods in forensic odontology rely on time-consuming manual measurements and reference tables, many of which rely on the correct determination of the tooth type. This study thoroughly explores the applicability of deep learning for sex assessment, age estimation, and tooth type determination from x-ray images of individual teeth. A series of models that use state-of-the-art feature extraction architectures and attention have been trained and evaluated. Their hyperparameters have been explored and optimized using a combination of grid and random search, totaling over a thousand experiments and 14076 hours of GPU compute time. Our dataset contains 86495 individual tooth x-ray image samples, with a subset of 7630 images having additional information about tooth alterations. The best-performing models are fine-tuned, the impact of tooth alterations is analyzed, and model performance is compared to current methods in forensic odontology literature. We achieve an accuracy of 76.41% for sex assessment, a median absolute error of 4.94 years for age estimation, and an accuracy of 87.24% to 99.15% for tooth type determination. The constructed models are fully automated and fast, their results are reproducible, and the performance is equal to or better than current state-of-the-art methods in forensic odontology.

Introduction. Ovarian cancer is the most lethal gynecological cancer. The most common manifestation of thoracic metastasis is pleural effusion. Pleural effusion with positive cytology is regarded as stage IVa of the International Federation of Gynecology and Obstetrics classification, and the overall five-year survival in these patients is less than 20%. We analyzed the data of patients with ovarian cancer who were treated at the Oncology Institue of Vojvodina, in order to establish the incidence of malignant pleural effusions, laterality of pleural effusions, and clinical manifestations. Material and Methods. The study included 731 patients with ovarian cancer who were treated at the Oncology Institue of Vojvodina from January 2012 to May 2020. The obtained data were compared with data found in the literature in the same period. Results. The incidence of malignant pleural effusion in our study was 5.75%; right-sided pleural effusion was found in 57.15% of patients, 33.33% of patients had effusion on the left side, and 9.52% had bilateral effusions. Thus, unilateral effusion was found in 90.48% of cases, and bilateral in only 9.52%. The most common symptom was dyspnea, reported in 33 patients (78.6%). Conclusion. The incidence of malignant pleural effusion in our study was most similar to data found by Zamboni et al. published in 2015; the right side was the dominant side of pleural effusions. The most common symptoms were dyspnea, shortnes of breath and chest pain.

Organophosphorus compounds induce irreversible inhibition of acetylcholinesterase, which then produces clinically manifested muscarinic, nicotinic and central effects. The aim of the study was to analyse the clinical signs of acute paraoxon poisoning in rats and to determine the relationship between the intensity of signs of poisoning and the dose of paraoxon and/or the outcome of poisoning in rats. Animals were treated with either saline or atropine (10 mg/kg intramuscularly). The median subcutaneous lethal dose (LD50) of paraoxon was 0.33 mg/kg and protective ratio of atropine was 2.73. The presence and intensity of signs of poisoning in rats (dyspnoea, lacrimation, exophthalmos, fasciculations, tremor, ataxia, seizures, piloerection, stereotypic movements) were observed and recorded for 4 h after the injection of paraoxon. Intensity of these toxic phenomena was evaluated as: 0 - absent, 1 - mild/moderate, 2 - severe. Fasciculations, seizures and tremor were more intense at higher doses of paraoxon and in non-survivors. In unprotected rats piloerection occurred more often and was more intense at higher doses of paraoxon as well as in non-survivors. In atropine-protected rats, piloerection did not correlate with paraoxon dose or outcome of poisoning. The intensity of fasciculations and seizures were very strong prognostic parameters of the poisoning severity.

Background/Aim: Coma is the most severe disturbance of consciousness from which the patient cannot wake up and in which there is no verbal and motor response or opening of the eyes. The aim of the research was to establish the frequency of occurrence of coma and the aetiology of coma in the Banja Luka Emergency Department (ED). Also, the goal was to analyse the accuracy of the referral diagnosis and potential factors that can help the doctor in making a correct diagnosis. Methods: A retrospective cross-sectional study was conducted. In the ED database, in the period from January to September 2022, all patients diagnosed with coma have been found. The gender and age of the patient, vital parameters, performed diagnostic methods and therapy were recorded. The referral diagnosis, the department to which the patient was referred, as well as the final diagnosis determined in hospital conditions were recorded. Results: In the period from January to September 2022 there were 95 patients who were diagnosed with coma. The average age of the patients was 67.76 ± 16.56 years, there were 56 (58.9 %) men and 39 (41.1 %) women. Of that number, 41 (43.2 %) patients were diagnosed with hypoglycaemic coma and those patients were treated in the field. Out of 54 patients, 32 (59.3 %) patients had a confirmed referral diagnosis, while 22 (40.7 %) patients had another diagnosis established at the hospital. All patients with suspected intracranial bleeding or stroke were correctly diagnosed and adequately referred, while all patients with a confirmed diagnosis of sepsis and shock were incorrectly referred (ch2 = 30.563, p < 0.001). Conclusion: The most frequent were coma caused by hypoglycaemia and coma caused by brain ischaemia and non-traumatic bleeding, which were adequately recognised and treated and/or referred. Coma caused by sepsis and shock of different aetiology was not recognised as such and was referred to a neurologist, where precious time was wasted. In order to reduce errors in the field, it is necessary to pay more attention to the anamnestic data on diseases and perform a somatic and neurological examination adequately.

Background / Aim: The concept of general balanced anaesthesia was devised in order to assure cardiovascular stability and fast post-anaesthesia recovery. This clinical trial was organised in order to investigate the parameters of cardiovascular function and emergence from anaesthesia in elective ear, nose and throat (ENT) surgery patients. Methods: A total of 40 ASA I and II patients of both sexes scheduled for elective ENT surgery were randomly divided into two equal groups. Both groups received a continuous IV infusion of glucose 5 % solution and in the esmolol group this infusion also contained esmolol. Esmolol infusion rate was 0.3 mg/kg/min during the first 5 min and thereafter 0.1 mg/kg/min. In critical phases of anaesthesia and operation (induction, intubation, first incision, surgical manipulations, wound suture, extubation), systolic and diastolic blood pressure were monitored. Recovery after anaesthesia was assessed based on times of eye opening on command, spontaneous eye opening and regaining of full orientation. Increases in cardiovascular parameters by 20 % of the baseline values or more were treated with IV boluses of fentanyl, alone or with droperidol and, if necessary, by adding isoflurane 0.5 % to the inhalational mixture. Consumption of drugs was recorded. Results: Esmolol assured stable values of cardiovascular parameters that were in most critical phases of anaesthesia and operation lower than in the control group. The duration of anaesthesia did not differ between the groups. In the esmolol group, lower consumption of fentanyl, droperidol and sevoflurane was registered. Patients in the esmolol group emerged from anaesthesia faster than patients in the control group. Conclusion: Continuous IV infusion of esmolol assures better cardiovascular stability, necessitates lower consumption of analgesics and anaesthetics and results in faster emergence from general anaesthesia in elective ENT surgery.

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.

Background/Aim: Breast-conserving surgery is a type of surgery used as a treatment option for breast cancer. It was introduced at the end of the 20th century following and in accordance with relevant clinical studies. With heightened public awareness of breast cancer and the introduction of new diagnostic procedures, despite the proven oncological safety of this type of surgery, a growing number of women choose to undergo total mastectomy. The aim of this study was to confirm the oncological safety of breast-conserving surgery performed on breast cancer patients at the University Clinical Centre of the Republic of Srpska. Methods: This study analysed 305 female patients with I and II stage of breast cancer, operated on between March 2009 and December 2013. One group of patients underwent breast-conserving surgery (BCS), followed by adjuvant radiation therapy and the other total mastectomy (MX). The patients were followed up for 5 years after the surgery. Analysed herein were the local-regional recurrence, distant metastases, disease-free survival and overall survival rates. Results: After a five-year follow-up, the local-regional recurrence rate for patients in the BCS group was 4.3 %, while for the MX group it was 4.2 %. The overall survival rate of patients in the BCS group was 90.9 %, as opposed to 89.1 % for MX patients. Conclusion: After a five-year follow-up, no statistically significant difference was observed between the two groups of patients regarding the local-regional recurrence (p = 0.967) and overall survival rates (p = 0.610). Breast-conserving surgery is an oncologically safe surgical treatment for breast cancer.

Background/Aim: Dehiscence of the colorectal anastomosis is one of the most serious complications in digestive surgery that is still present in a large percentage today, which significantly increases the cost of treatment and can lead to death. Due to all the above, early detection of anastomotic dehiscence is very important, as well as the decision on surgical treatment. Procalcitonin (PCT) is thought to be an important marker of inflammation and sepsis. Aim of this paper was to confirm PCT as a marker of great sensitivity in early diagnosis of anastomotic leakage. Methods: The study included patients who underwent surgery for colorectal cancer in the period from 2016 to 2020. Patients were operated according to an elective protocol and with an open surgical approach. In patients, PCT values were measured on the 2nd and 4th postoperative day (POD) to determine the association between elevated PCT values and the onset of dehiscence of the colorectal anastomosis. Results: A study was conducted in 118 patients in whom a stapler colorectal anastomosis was created. Colorectal anastomosis dehiscence occurred in 10 patients. In 4 patients with dehiscence, no re-surgical intervention was required, but they were taken care of by conservative methods. Repeated surgery was performed in 6 patients. In all patients with dehiscence, there was a multiple increase in the value of PCT above normal. Conclusion: PCT has high sensitivity and specificity (85 and 74 % respectively) as a marker in dehiscence of colorectal anastomosis. In this study it was found that PCT values were significantly correlated with the dehiscence of anastomo-sis 2nd POD and especially 4th POD.

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.

Leser-Trélat (LT) sign (syndrome) is a rare, distinctive clinical phenomenon that is manifested by a sudden, eruptive, appearance of multiple itchy seborrheic keratoses (SK) that sometimes coincide with occult malignancy. A 73-year-old patient came for examination of numerous, large seborrheic keratoses (SK) on the skin. According to the patient's statement, SK did not occur suddenly and "eruptively". Nevertheless, ultrasound and endoscopic evaluation were suggested to the patient to exclude the Leser-Trélat phenomenon. The patient was then diagnosed with an occult, asymptomatic rectal neoplasm. The occurrence of numerous seborrheic keratoses (especially if they are "eruptive", large and bizarre in shape), should raise suspicion of LT phenomenon, or internal malignancy in the patient, and result in relevant diagnostic procedures to detect possible latent malignancy. It would be wise for the doctors of all disciplines to be acquainted with the existence of the LT sign (syndrome) and possible clinical implications of it.

Introduction/Objective. The aim of this study was to examine the immunohistochemical features of the vascularization of the anterior cruciate ligament (ACL), as well as the quantification of capillaries within the three segments of the ACL; proximal, middle and distal. The quantification and metric characteristics of mast cells of the ACL are the second goal of this research. Methods. Thirty human ACL of 30 persons, obtained during routine autopsy, were examined under the microscope, following immunohistochemical reactions against CD34 of blood vessels and MastTrip of mast cells. Results The middle genicular artery (MGA) close to the ACL gave off branches for the supply of ligament itself. Each field of mm2 contained an average number of 1113.84 (959-1240), microvessels in ACL proximal third, an average number of 1145.43 (924-1310) microvessels in ACL middle third, and an average number of 1134.55 (889 to 1451) microvessels in ACL distal third. An average number of mast cells of the ACL was 3.8 per mm2. In the peripheral synovial zone of the ACL we counted 12.6 mast cells per mm2. An average area value of the mast cells was 124.7 ?m2, and an average value of shorter and longer axis of the mast cells was 11.2 x 15.0 ?m. Conclusion. There was no statistically significant differences between the average numbers of intraligamentous microvessels of the ACL thirds (p>0.05), confirming and supporting our hypothesis of uniform distribution of blood supply within the ACL.

Background/Aim: Unintentional injuries among children and adolescents have become a common issue in public healthcare. The study objective was to analyse the characteristics and identify predictors associated with unintentional injuries in children and adolescents treated in emergency medical services (EMS) in the Republic of Srpska, Bosnia and Herzegovina. Methods: A cross-section study with retrospective analysis of WebMedic e-database from 14 EMS, in the period between January 2018 and December 2020 was conducted. Research included patients with unintentional injuries, aged ≤ 19 years, of both sexes. For comparison between groups, Chi-squared and multivariate logistic regression were used in risk factor analysis. Results: A total of 1,856 cases were identified, most injuries resulted from falls (46.7 %) and traffic injuries (26.9 %). Boys were significantly more affected by injuries than girls (p < 0.001). Falls were the major cause for reporting to EMS among age groups of children (0-9 years) and adolescents (10-14 years), whereas injuries in traffic were dominant in adolescents aged 15 to 19. The most common injuries were head injuries (35.7 %). Risk factors of unintentional injuries were age (p < 0.001), sex (p = 0.046), weekday (p = 0.016), winter (p = 0.014), body region (head, abdomen, lower and upper limbs (p < 0.001), thorax (p = 0.009)). Conclusions: There were significant differences in characteristics of unintentional injuries according to age and sex. Chances for occurrence of unintentional injuries among children increased with their age, especially for boys. These differences might indicate areas where preventive measures should be undertaken.
