Background/Aim: The objective of this research was to evaluate the level of oral hygiene, the prevalence of caries, and the condition of the soft tissues in children and adolescents referred for their first orthodontic examination. Material and Methods: The research was conducted at the Department of Orthodontics of Sarajevo University - at the Faculty of Dentistry with the Dental Clinical Center. A total of 300 patients with mixed and permanent dentition who were referred for their first orthodontic examination were included in the study. The patients were offered to sign a Letter of Informed Consent for this study. All patients were assigned a Decayed, Missing, and Filled Teeth (dmft/DMFT) index. Periodontal indices were evaluated on all first permanent molars and all permanent central incisors. The periodontal indices included the determination of PI,CI,GI, PBI. Results: The results were processed with the application of standard statistical methods, by using the SPSS computer program for statistical analyses (SPSS-Statistical Package for Social Sciences) Version 21.0. The results of this study show a high dmft and DMFT indices in patients referred for orthodontic examination. The dmft index value in the respondents with mixed dentition was 3.0 (1.0 - 6.0). The DMFT index value in the respondents with permanent dentition was 4.0 (0.0 - 6.0), while in the respondents with mixed dentition, it was 1.0 (0.0 - 3.0). Our research also shows that out of 300 patients referred to an orthodontist for their first orthodontic examination, 250 of them (83.33%) have demonstrated an increased value of the Plaque index. Conclusions: The results of this research should be peculiarly alarming for pedodontists and general dentists, cautioning them to implement caries prevention measures more intensively and make referrals to an orthodontist only in case of those patients who have been cured previously.

The Una-Sana Canton (the northwest part of Bosnia and Herzegovina) abounds in large forest areas, where the self-sown sweet chestnuts Castanea sativa Mill. grow. However, the plant has been endangered due to the negative effects of disease-causing agents, harmful insects, and human factors (uncontrolled forest logging). Moreover, the chestnut weevil Curculio elephas causes significant damage to the local chestnut fruit. This study aims to analyze the emergence of the pest and the damage which it produces in the forest areas of the northwestern Bosnia and Herzegovina, precisely in Una-Sana Canton. The presence of the chestnut weevil has been examined on samples taken from 15 locations in chestnut forest in the municipalities of Cazin, Velika Kladuša and Bužim. In order to research this phenomenon more precisely, each fruit has been cut, the larvae have been separated from it and damage in the inner part of the fruit has been observed. The number of larvae has been noted per a sample. With respect to each sample, the mass of healthy and damaged part of the fruit has been measured. The number of larvae ranges from 5 to 15 per sample. The percentage of damaged fruit parts ranges from 4,2% to 13,6%. The reason for the increased presence of the chestnut weevil in the analyzed chestnut forest is in addition to the beneficial chemical composition of the fruit and the late detection of the presence of insect existing in severely large populations. The use of chemical preparations (pesticides) as a solution to this issue is ecologically unacceptable, especially in a larger area. It is mandatory to manually collect all the fruit that fells of the chestnut trees prematurely and, moreover, to stop the further development of the larvae. Considerable results can also be achieved by separating individual chestnut stands and changing the purpose of its use, as well as combining the method with the limited use of pesticides.

This article aims to summarise the current situation regarding digital archaeological archives in Bosnia and Herzogivina.

Background: Bone morphogenetic protein -4 (BMP-4) plays important role in many aspects of carcinogenesis but is also involved in progression and metastasis of breast cancer where its precise role is yet to be elucidated. Objective: Since the majority of studies related to BMP-4 expression in breast cancer were conducted on cell lines of mouse models, we aimed to investigate BMP-4 tissue expression in primary human breast cancer and to correlate it with standard pathological factors for breast cancer, progression and survival. Methods: We analyzed immunohistochemical expression of BMP-4 in primary breast cancer tissue of 97 patients, correlated it with standard pathological factors for breast cancer and investigated its impact on progression and survival. Results: BMP-4 expression was positive in 74.23% breast cancer tissue specimens. We found that hormone positive breast tumors are more likely to show BMP-4 strong granular staining pattern (p<0.01; p=0.029, respectively). There was significant association between stage group and BMP-4 expression in order that stage III breast cancer group were predominantly BMP-4 positive tumors (p=0.046). Although the most common site of distant metastases in patients with BMP-4 positive tumors were bones, we found no significant association (p>0.05). Patients with BMP-4 positive breast cancer showed longer overall and progression-free survival, but the results did not reach statistical significance (p>0.05). Conclusion: The results of our study in some extent can confirm the current available data and suggest that the role of BMP-4 in breast cancer is ambiguous, acting both as tumor suppressor and tumor promoter in breast cancer. For final elucidation of its impact on survival and progression in breast cancer, multicentric studies on larger sample size are required.

Introduction/Objective. The purpose of this study was to assess the effectiveness of different approaches in the treatment of metastatic melanoma in daily clinical practice in a situation with limited and late availability of new drugs in a resource-limited country and to compare these parameters with those reported in clinical studies and from other real-world data. Methods. Main methods included assessment of overall survival (OS) and progression-free survival (PFS). Patients were included in the study if they were treated with first or second-line systemic therapy for radiologically/pathologically confirmed metastatic melanoma. Patients were divided into four groups based on the type of therapy they received: chemotherapy (dacarbazin), BRAF inhibitor (vemurafenib), BRAF/MEK inhibitors (vemurafenib/cobimetinib and trametinib/dabrafenib) and anti PD-1 therapy with pembrolizumab. Results. Regardless of the line of therapy, the calculated median OS in chemotherapy and vemurafenib group was nine months. The median OS in the BRAF/MEK inhibitor group was 14 months and 15 months in the pembrolizumab group. Median PFS in the chemotherapy group was four months, seven months for vemurafenib, in the BRAF/MEK inhibitor group nine months and in the pembrolizumab group six months. There was a statistically significant difference in survival between first and second-line therapy in the pembrolizumab group. Conclusion. Our results showed lower median OS and PFS in comparison to reported data from clinical trials. Compared to other real-world data from countries with similar problems related to the late reimbursement of new drugs, our research has shown similar results.
