Background: Chordoma is a rare malignant neoplasm that predominantly arises from the axial skeleton, but can also develop in unusual locations. However, there are also rare cases of „NOS“ chordoma involving the oropharyx and epithelial-myoepithelial carcinoma of the parotid gland in the same patient. According to contemporary research, chordoma is a rare malignant neoplasm that arises from the embryonic remnants of the notochord. and typically involves the clivus, sacrococcygeal bones or vertebrae. Studies have shown that the incidence of chordoma has been estimated to be one per one million people per year. Chordoma can occur at any age, but most commonly it is diagnosed in the 40–60 year old age group with the male predominance. Objective: The aim of this article was to review the case of a 74-year-old female patient with epithelial-myoepithelial carcinoma of the parotid gland and a case of „NOS“ chordoma involving the oropharyx. Methods: Diagnostic methods were used to examine a female patient with two primary malignant tumors: CT neck scan, CT of paranasal sinuses, ultrasound examination, scintigraphy and operative finding. Case presentzation: Due to the anatomy complexity, complete resection of the tumor through a transoral-transpharyngeal approach was not possible. Intraoperative palpation of the mass revealed well defined submucosal lesion 20x43x46mm beginning at the level of the oro- and hypopharynx and extending superiorly to the nasopharynx, and posteriorly into the spinal canal and intervertebral foramen causing near complete occlusion of the oro and hypopharynx. The patient also underwent extracapsular dissection of the parotid tumor. Postoperative palliative radiotherapy was performed. Conclusion: Surgical treatment remains the mainstay of treatment for EMC and radiation is imperative for patients who refuse surgery and for those with advanced or inoperable diseases.

Background: Lyme borreliosis is a multisystemic infection caused by the spirochete Borrelia burgdorferi. Erythema migras is the main clinical marker of the disease. Objective: This study aimed was to investigate the frequency and clinical manifestations of European borreliosis on the skin, and to determine the significance of these findings for diagnosis and therapy. Methods: A retrospective-prospective clinical study of outpatients treated and monitored in a private clinic of an infectologist was conducted over nine years from to 2013-2021. The study was clinical, descriptive and analytical in nature. Results: In the investigated period, 509 (30.8%) patients with borreliosis symptoms were treated. EM in our patients occurred under the following conditions: a) ringed redness, b) redness of target cels and d) continuous round or oval redness of different sizes of individual redness, or multiple occurrences with primary dissemination. Skin changes with multiorgan chronic symptoms of borreliosis occurred in 67.7% of cases the including: walking redness of different shapes and sizes, pink borreliosis stretch marks, white borreliosis stretch marks, borreliosis palms and soles, psoriatic changes, Acrodermatitis chronica atrophicans, Scleroderma circumscripta-morphae, Erythema nodosum, Granuloma anulare and Lichen striatus et atrophicans. Of the 509 patients treated for borreliosis, 32.3% with multi-organ symptomatology had no skin changes. Conclusion: The skin manifestations of European borreliosis are multi-layered and Erythema migrans are basic, but not the only markers of the disease. ‘Pink borreliose stretch marks, “white borreliosis striae”, “borreliosis palms or soles”, and intermittent redness accompanied by itching are unique markers for the diagnosis of chronic borreliosis, if they are manifested.

To behave in a socially responsible manner and to support the concepts of sustainable development, organizations apply various processes and activities for greening their business. In addition to green marketing, supply and distribution chain, production, packaging and recycling, green human resources management (GHRM) also plays a big role. For this purpose, organizations incorporate a green component into all human resources management (HRM) phases, thereby building a green employer brand. This paper examines the extent to which organizations in Serbia and Bosnia and Herzegovina apply GHRM activities and practices, and whether there are differences in the application of these practices depending on the size and business sector. Empirical research carried out in Serbia and Bosnia and Herzegovina has found that green activities and HRM practices are applied to a small extent, with slightly higher results achieved by small and manufacturing organizations. The findings indicate the need for greater engagement of organizations to strengthen the awareness of the importance of GHRM, support their sustainable development and strengthen the brand in domestic and foreign markets.

The aim of the research was to examine the prevalence of unpleasant emotional states among students. An online survey was conducted in the month of April, 2023, and the participants were students of public universities in Bosnia and Herzegovina (N=170). Among the measuring instruments used was the DASS-21questionnaire (The Depression, Anxiety and Stress Scale-21, Lovibond and Lovibond 1995) and a sociodemographic questionnaire, constructed for the purposes of this research. It is expected that students will experience unpleasant emotional states such as anxiety, depression and stress, and that there will be certain differences in the manifestation of symptoms with regard to gender and age. The obtained findings showed that 34.3% of the subjects are in the category of moderate, severe and extremely severe depressive symptoms, then 49,9% of the subjects feel moderate, severe or extremly severe anxiety, while 38.2% of the subjects show moderate, severe and extremly severe symptoms of stress. As for gender and age differences, the results show that female students are more susceptible to the prevalence of unpleasant emotional states, while the hypotesis related to age differences was not confirmed. Namely, the findings indicate that there are no age differences in the manifestation of unpleasant emotional states. Considering the obtained findings, we believe that it is necessary to raise awareness about the significant growing problems of mental health among students and to highlight the need for preventive and intervention programs at universities.
